  anatomical location - lungs and the airways

etiology: the primary etiology of the patient's problem could be the the occupation of the patient . The patient works in a paddy field which increases the risk of being exposed to fine dust. Prolonged exposure to the dust can cause COPD (most common cause being smoking) 

                                           

QUESTION: What are mechanism of action, indication and efficacy over placebo of each of the pharmacological and non pharmacological interventions used for this patient?

   ANS) 1)Head end elevation_ 30-45°

. It is recommended in this patient since she is on mechanical ventilation to reduce the incidence of VENTILATOR ASSOCIATED PNEUMONIA that occurs due to aspiration of contaminated oropharyngeal secretions following endotracheal tube intubation. 

 Efficacy based on studies: Moderate quality evidence from eight studies involving 759 participants demonstrated that a semi-recumbent (30º to 60º) position reduced clinically suspected VAP by 25.7% when compared to a 0° to 10° supine position. 

 2)O2 inhalation-

 It is given for this patient as her spo2 levels at the time of presentation were 75% at room air

.Indication for o2 inhalation: supplemental o2 therapy / inhalation is given when spo2 levels are below <92% at room air.

 3)Intermittent BiPAP-

 Bilevel positive airway pressure (BiPAP) ventilation is a non invasive technique  used to provide support to a spontaneously, but insufficiently, breathing patient using a  nasal mask. 

MOA:

 BiPap machine supplies pressurized air into your airways. It is called “positive pressure ventilation” because the device helps 

     open your lungs with this air.

 The machine has 2 pressure settings

   1) for inhalation IPAP

    2) low pressure foe exhalation EPAP

.Indication: it is given to the patient to provide respiratory support as she is diagnosed with COPD.

 4)Injection Augmentin 1.2gm IV /BO

 .It is given to the patient to treat Broncheictasis

 .augmentin is a combination of

  AMOXICILLIN- binds to penicillin binding proteins in bacterial cell wall and thereby inhibits bacterial  cell wall synthesis.

  CLAVULINIC ACID - is a beta lactamase enzyme inhibitor , thereby facilitates action of Amoxicillin.

 MOA-

Amoxicillin binds to penicillin-binding proteins within the bacterial cell wall and inhibits bacterial cell wall synthesis. Clavulanic acid is a β-lactam, structurally related to penicillin, that may inactivate certain β-lactamase enzymes.

 5)Tab. Azithromycin 500mg OD

  .It is given to the patient to provide symptomatic relief and reduce incidence of acute exacerbations of COPD.

MOA-

Azithromycin binds to the 23S rRNA of the bacterial 50S ribosomal subunit. It stops bacterial protein synthesis by inhibiting the transpeptidation/translocation step of protein synthesis and by inhibiting the assembly of the 50S ribosomal subunit 

 EFFICACY BASED ON A STUDY:

A randomized controlled trial found that patients hospitalized for an acute exacerbation of chronic obstructive pulmonary disease (COPD) experienced reduced rates of treatment failure when adding azithromycin to their standard of care.

 During the study, patients received a low dose of azithromycin in addition to their prescribed medications while in the hospital and continued taking the antibiotic for 3 months following hospitalization. The result, according to the data, was reduced treatment failure compared with standard of care alone. Rates of treatment failure were under 50% for patients taking azithromycin (49%) compared with 60% for patients receiving standard of care.

 6)INJ. LASIX IV BO if SBP greater than 110 mmHg

.It is given to the patient to relieve symptoms of fluid retention(edema)

.It is also used to treat hypertension

.MOA:

Furosemide(LASIK) acts by inhibiting the luminal Na-K-Cl cotransporter in the thick ascending limb of the loop of Henle,

                                                                                            

                                              increase the excretion of Na+ and water by the kidneys

                                                                                           

                                                                         Increased urine output

 7)TAB PANTOP 40mg PO OD

 MOA-

The mechanism of action of pantoprazole is to inhibit the final step in gastric acid production. In the gastric parietal cell of the stomach, pantoprazole covalently binds to the H+/K+ ATP pump to inhibit gastric acid and basal acid secretion. The covalent binding prevents acid secretion for up to 24 hours and longer.

 8)INJ. HYDROCORTISONE 100 mg IV 

. It acts by reducing inflammation in the body

MOA-

Hydrocortisone binds to the glucocorticoid receptor leading to downstream effects such as inhibition of phospholipase A2, NF-kappa B, other inflammatory transcription factors, and the promotion of anti-inflammatory genes.

Based on a study in comparison to placebo, systemic corticosteroids 

1)improved airflow,

2) decreased the rate of treatment failure and risk of relapse 

improved symptoms and decreased the length of hospital stay. 

 EFFICACY:

In this study, patients hospitalized with acute respiratory insufficiency and COPD were randomized to receive either intravenous (IV) corticosteroid (n=22) or matching placebo (n=22) for 72 hours. All patients received standardized treatment consisting of oxygen, aminophylline, nebulized isoproterenol, and antibiotics. The mean percentage change in both pre- and postbronchodilator forced expiratory volume in 1 second (FEV1) was significantly greater in patients receiving corticosteroid in comparison to placebo at all measured time points. 

 9)NEB. with IPRAVENT, BUDECORT 6 hrly

MOA-

ipravent belongs to a group of medicines known as anticholinergic bronchodilators, work by relaxing the bronchial tubes that carry air in and out of your lungs and makes breathing less difficult.

BUDECORT (Budesonide ) belongs to a group of medicines called 'corticosteroids'. It works by reducing and preventing swelling and inflammation in your lungs’. 

EFFICACY-

Efficacy based on a study where Patients received 2 mg of budesonide every 6 h (n = 71),placebo (n = 66). All received standard treatment, including nebulized beta(2)-agonists, ipratropium bromide, oral antibiotics, and supplemental oxygen. The mean change (95% confidence interval) in postbronchodilator FEV(1) was greater with active treatments than with placebo: budesonide versus placebo, 0.10 L (0.02 to 0.18 L)

 10)TAB PULMOCLEAR 100 mg PO OD

Pulmoclear Tablet is a combination of two mucolyticmedicines: 

   1)  Acebrophylline 

     2) Acetylcysteine. 

It thins and loosens mucus (phlegm) making it easier to cough

It also relaxes the airway muscles and thereby promotes easy inflow and outflow of air

 11)chest physiotherapy

Chest physiotherapy improves lung function . ChestPT, or CPT expands the lungs, strengthens breathing muscles, loosens and improves drainage of thick lung secretions.

 12)GRBS 6 hrly -

 .to monitor blood sugar levels

 13)INJ. HAI SC ( 8 am- 2pm- 8pm)

 Human Actrapid Injection contains human insulin(short acting)

 It is given to the patient to lower blood sugar levels as she is a diabetic.

 14)Temp, BP, PR, SPO2 monitoring 

 15)I/O charting - 

           Is used to record fluid intake and output

 16)INJ. THIAMINE 1 amp in 100 ml of NS

MOA-

Thiamine combines with adenosine triphosphate (ATP) in the liver, kidneys, and leukocytes to produce thiamine diphosphate. Thiamine diphosphate acts as a coenzyme in carbohydrate metabolism, in transketolation reactions, and in the utilization of hexose in the hexose-monophosphate shunt.

EFFICACY-

  Based on a study-  The administration of a single dose of thiamine was associated with a trend toward increase in oxygen consumption in critically ill patients

.thiamine deficieny is seen in patients taking loop diuretics(lasik), as this patient is receiving LASIK, the use of thiamine could be prophylactic.

                                    

QUESTION:What could be the causes for her current acute exacerbation?

The patient has three factors causing an exacerbation:

1.      1)History of the previous attacks

2.       2)The patient is a known case of hypertension this can lead to an increase in the pressure of the pulmonary artery. The resulting hypoxia will further exacerbate the condition leading to right sided heart failure

3.       3)She also is a known case of diabetes which is a risk factor 

What could be the causes for her electrolyte imbalance?

Answer: 

The cause of Hyponatraemia and Hypochloremia can be due vigorous high ceiling diuretic therapy in order to control right heart failure.

            

SYSTEM: NEUROLOGY

QUESTION: What is the evolution of the symptomatology in this patient in terms of an event timeline and where is the anatomical localization for the problem and what is the primary etiology of the patient's problem?

 

The evolution of the symptomatology is as follows:

 

1 year ago

First episode of seizure

 

4 months ago

Second episode of seizure (24 hours after with the withdrawal of alcohol, leading to restlessness, sweating and tremors)

 

9 days ago

Started talking and laughing to himself, decreased food intake, unable to recognize family members, has short term memory loss.

 

 

Anatomical localization: There are lesions in the peripheral and central nervous system

 

Etiology:

Since the Patient has a history of consumption of alcohol, this will lead to a deficiency in thiamine. A thiamine deficiency gives rise to Wernicke’s Encephalopathy.

https://www.ncbi.nlm.nih.gov/books/NBK470344/

https://med.virginia.edu/ginutrition/wp-content/uploads/sites/199/2014/06/ThomsonArticle-09.pdf

Thiamine, also known as Vitamin B1, is a coenzyme that is essential for intricate organic pathways and plays a central role in cerebral metabolism. This vitamin acts as a cofactor for several enzymes in the Krebs cycle and the pentose phosphate pathway, including alpha-keto-glutamic acid oxidation and pyruvate decarboxylation. Thiamine-dependent enzymes function as a connection between glycolytic and citric acid cycles. Therefore, deficiency of thiamine will lead to decreased levels of alpha-keto-glutarate, acetate, citrate, acetylcholine and accumulation of lactate and pyruvate. This deficiency can cause metabolic imbalances leading to neurologic complications including neuronal cell death.

 

QUESTION: What are mechanism of action, indication and efficacy over placebo of each of the pharmacological and non-pharmacological interventions used for this patient?

 

1)IVF NS and RL @150ml/hr

- Normal saline and ringer lactate solutions are both crystalloid fluids. NS contains 154 mM Na+ and Cl-, with an average pH of 5.0 and osmolarity of 308 mOsm/L. LR solution has an average pH of 6.5, is hypo-osmolar (272 mOsm/L), and has similar electrolytes (130 mM Na+, 109 mM Cl-, 28 mM lactate, etc.) to plasma.\

2)Inj. 1amp THIAMINE in 100ml NS, TID

- Thiamine is given in patients that are chronic alcoholics, due to the pathology which causes the thiamine levels in the body are deficient and thiamine is required in the breakdown of glucose.

-efficacy:https://www.cochrane.org/CD004033/DEMENTIA_thiamine-for-prevention-and-treatment-of-wernicke-korsakoff-syndrome-in-people-who-abuse-alcohol

in the above study randomised controlled trials comparing thiamine with placebo or alternative treatments, or comparing different thiamine treatments. Two studies were identified that met the inclusion criteria, but  one reported no data that they could analyse, and analysis of the other study was limited by shortcomings in design and in presentation of the results. 

3)Inj. Lorazepam

Lorazepam is mostly given to reduce the anxiety the patient feels.

Mechanism of action: Lorazepam binds to benzodiazepine receptors on the postsynaptic GABA-A ligand-gated chloride channel neuron at several sites within the central nervous system (CNS). It enhances the inhibitory effects of GABA, which increases the conductance of chloride ions into the cell.

Efficacy study: https://pubmed.ncbi.nlm.nih.gov/6120058/#:~:text=Subjective%20and%20objective%20data%20clearly,(P%20less%20than%200.01).

 Subjective and objective data clearly demonstrated that lorazepam was effective for both inducing and maintaining sleep. Sleep latency was reduced from a baseline value of 34.6 min to 17.9 min

4)T. Pregabalin 75mg/PO/ BD

Mechanism of action: Pregabalin has demonstrated anticonvulsant, analgesic, and anxiolytic properties in preclinical models. The drug's exact mechanism of action is unclear, but it may reduce excitatory neurotransmitter release by binding to the α2-δ protein subunit of voltage-gated calcium channels.

Indication: Pregabalin is indicated for the management of neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, fibromyalgia, neuropathic pain associated with spinal cord injury, and as adjunctive therapy for the treatment of partial-onset seizures in patients 1 month of age and older.

 Efficacy:https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2453685/#:~:text=RESULTS%E2%80%94Pooled%20analysis%20showed%20that,BID%20(P%20%E2%89%A4%200.001).

CONCLUSIONS—Treatment with pregabalin across its effective dosing range is associated with significant, dose-related improvement in pain in patients with DPN.

5)Lactulose 30ml/PO/BD

Mechanism of action: 

efficacy:https://pubmed.ncbi.nlm.nih.gov/21971378/

Conclusion: Lactulose has significant beneficial effects for patients with MHE compared with placebo or no intervention.

6)Inj 2 ampoule KCl (40mEq) in 10 NS over 4 hours

Mechanism of action: Supplemental potassium in the form of potassium chloride may be able to restore normal potassium levels.

Indication: For use as an electrolyte replenisher and in the treatment of hypokalemia.

 efficacy: https://pubmed.ncbi.nlm.nih.gov/2310280/

7)Syp Potchlor 10ml in one glass water/PO/BD

It is a supplement potassium and helps in replenishing in cases of hypokalemia

 

QUESTION: Why have neurological symptoms appeared this time, that were absent during withdrawal earlier? What could be a possible cause for this?

 

The patient mainly deals with two main neurological symptoms- seizures and memory loss

The process of repeated alcohol intake and withdrawal is known as kindling. During the kindling effect, the brain and body become incredibly sensitive to alcohol and the withdrawal symptoms that occur during cessation. Every relapse and subsequent detox from alcohol becomes more intense and painful. More severe withdrawal symptoms can occur because of the kindling effect during each incidence of relapse and withdrawal. The risk of seizures and a potentially dangerous condition called delirium tremens increase due to the kindling effect.

 Alcohol may have a direct neurotoxic effect on cortical neurons, but much of the damage may be secondary to a pre-existing pathology caused by thiamine deficiency.

The continuous use of alcohol must have resulted in thiamine deficiency which could be causing neurological symptoms. Previously there must have not been a decrease in levels of thiamine in a patient and that can be the reason why he never displayed neurological symptoms before. With increase in alcohol and withdrawal processes the patient’s thiamine deficiency is now causing neurological symptoms

 

QUESTION: What is the reason for giving thiamine in this patient?

 

-Thiamine is usually given in patients with this type of presentation because of the history of alcohol withdrawal and alcohol habituation.

-A chronic alcoholic has a depleted supply of thiamine in the body which can give rise to neurological symptoms, such as Wernicke Encephalopathy.

-To abate some of the symptoms, thiamine is given to replenish the supply of the patient.

 

QUESTION: What is the probable reason for kidney injury in this patient? 

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6826793/

 

Both acute and chronic alcohol consumption can compromise kidney function, particularly in conjunction with established liver disease. Excessive alcohol consumption can have profound negative effects on the kidneys and their function in maintaining the body’s fluid, electrolyte, and acid-base balance, leaving alcoholic people vulnerable to a host of kidney-related health problems.: Chronic alcohol consumption induces profound injury in several organs that may affect and aggravate the effect of ethanol on the kidney. Ethanol itself markedly induces the expression of the microsomal ethanol oxidation system (CYP2E1), producing reactive oxygen species as a byproduct. Increased gastrointestinal permeability and endotoxin load may lead to alcoholic steatohepatitis resulting in excessive immunoglobulin A (IgA) load. IgA deposits may accumulate in the kidney, leading to glomerulopathy. Renal microcirculatory changes in advanced liver cirrhosis leads to hepatorenal syndrome. Alcohol-induced skeletal muscle damage leads to excessive amounts of circulating myoglobin, causing renal tubular injury because of increased oxidative stress. Due to the development of alcoholic cardiomyopathy, chronic renal hypoxia develops, activating the renin–angiotensin–aldosterone system (RAAS), which in turn leads to further free radical production and to the propagation of fibrotic pathways.

Though there only a few studies which talk about the alcohol’s direct effect on kidney. Alcohol cause various other imbalances which cause decrease in their function.

 

QUESTION: What is the probable cause for the normocytic anemia?

 

Kidney disease is associated with normocytic anemia

 

QUESTION: Could chronic alcoholism have aggravated the foot ulcer formation? If yes, how and why?

Similar to diabetes chronic alcoholism causes a depression in the immune system. This can aggravate the for ulcer formation.  It can also cause alcoholic neuropathy Alcoholic neuropathy involves coasting caused by damage to nerves that results from long term excessive drinking of alcohol and is characterized by spontaneous burning pain, hyperalgesia, and allodynia. Chronic presentation will increase the chances of foot ulcer formation and also increase the time of recovery.   

                                                   

CASE: https://kausalyavarma.blogspot.com/2021/05/a-52-year-old-male-with-cerebellar.html?m=1

 

QUESTION: What is the evolution of the symptomology in this patient in terms of an event timeline and where is the anatomical localization for the problem and what is the primary etiology of the patient’s problem?

Timeline of the patient is as follows-

7 days back

a history of giddiness that started around 7 in the morning; subsided upon taking rest; associated with one episode of vomiting

4 days back

Patient consumed alcohol; He developed giddiness that was sudden onset, continuous and gradually progressive. It increased on standing and while walking.

H/O postural instability- falls while walking

Associated with bilateral hearing loss, aural fullness, presence of tinnitus

Associated vomiting- 2-3 episodes per day, non-projectile, non-bilious without food particles

 

Present day of admission

Slurring of speech, deviation of mouth that got resolved the same day

 

Anatomical location- There is a presence of an infarct in the inferior cerebellar hemisphere of the brain.

Etiology- Ataxia is the lack of muscle control or co-ordination of voluntary movements, such as walking or picking up objects. This is usually a result of damage to the cerebellum. There are many conditions causing ataxia such as head trauma, alcohol abuse, stroke, tumors, cerebral palsy etc. this patient was diagnosed with hypertension for which he was prescribed medication but the patient did not use the medication. This must have caused uncontrolled blood pressure leading to stroke.

QUESTION: What are the mechanism of action, indication and efficacy over placebo of each of the pharmacological and non-pharmacological interventions used for this patient?

ANS.

1)Tab Vertin 8mg-

This is an anti-vertigo medication known as betahistine

MOA-Betahistine has two mechanisms of action. Primarily, it is a weak agonist on the H1 receptors located on blood vessels in the inner ear. This gives rise to local vasodilation and increased permeability, which helps to reverse the underlying problem of endolymphatic hydrops.

More importantly, betahistine has a powerful antagonistic effects at H3 receptors, thereby increasing the levels of neurotransmitters histamineacetylcholinenorepinephrineserotonin, and GABA released from the nerve endings. The increased amounts of histamine released from histaminergic nerve endings can stimulate receptors

Indications- Prescribed for balance disorders. In this case it is used due to patient’s history of giddiness and balance issues.

2)Tab Zofer 4mg-

This is ondanseteron, an anti-emetic

MOA- It is a 5H3 receptor antagonist on vagal afferents in the gut and they block receptors even in the CTZ and solitary tract nucleus.

Indications- Used to control the episodes of vomiting and nausea in this patient.

3)Tab Ecosprin 75mg-

This is a NSAID(aspirin)

MOA- They inhibit COX-1 and COX-2 thus decreasing the prostaglandin level and thromboxane synthesis

Indications- They are anti platelet medications and in this case used to prevent formation of blood clots in blood vessels and prevent stroke.

efficacy: https://pubmed.ncbi.nlm.nih.gov/3966266/

40 mg aspirin daily inhibited platelet responses as effectively as higher doses of aspirin in patients who had recent cerebral ischemia and showed a cumulative antiplatelet effect.

4)Tab Atorvostatin 40mg-

-This is a statin

MOA- It is an HMG CoA reductase inhibitor and thus inhibits the rate limiting step in cholesterol biosynthesis. It decreases blood LDL and VLDL, decreases cholesterol synthesis, thus increasing LDL receptors in liver and increasing LDL uptake and degeneration. Hence plasma LDL level decreases.

Indications- Used to treat primary hyperlipidemias. In this case it is used for primary prevention of stroke

efficacy: https://pubmed.ncbi.nlm.nih.gov/17910521/.

atorvastatin has developed a well defined role in the primary and secondary prevention of cerebrovascular disease, and appears to have a particularly prominent place in preventing such disease in CHD patients, and in the post-stroke and post-TIA setting in patients without CHD

5)Clopidogrel 75mg-

-It is an antiplatelet medication

MOA- It inhibits ADP mediated platelet aggregation by blocking P2Y12 receptor on the platelets.

Indications- In this case it decreases the risk of heart disease and stroke by preventing clotting

6)Thiamine-

- It is vitamin B1

 In this case, the patient consumes excess alcohol which can cause thiamine deficiency causing many neurological disorders.

Indications- Given to this patient mainly to prevent Wernicke’s encephalopathy- that can lead to confusion, ataxia and opthalmoplegia.

7)Tab MVT-

-This is methyl cobalamin

-given to the patient for vit b12 deficiency

QUESTION: Did the patients history of DE novo hypertension contribute to his current condition?

High blood pressure damages arteries throughout the body, creating conditions where they can burst or clog more easily. Weakened arteries in the brain, resulting from high blood pressure, put you at a much higher risk for stroke. high blood pressure can cause several problems in the brain, including:

Transient ischemic attack (TIA). Sometimes called a ministroke, a TIA is a brief, temporary disruption of blood supply to your brain. Hardened arteries or blood clots caused by high blood pressure can cause TIA. TIA is often a warning that you're at risk of a full-blown stroke.

Stroke. A stroke occurs when part of your brain is deprived of oxygen and nutrients, causing brain cells to die. Blood vessels damaged by high blood pressure can narrow, rupture or leak. High blood pressure can also cause blood clots to form in the arteries leading to your brain, blocking blood flow and potentially causing a stroke.

QUESTION: Does the patient’s history of alcoholism make him more susceptible to ischemic or hemorrhagic stroke?

According to a Cambridge study, heavy drinkers have 1.6 more chance of intracerebral hemorrhage and a 1.8 increased chance of subarachnoid hemorrhage. The adverse effect on BP that is seen due to increased drinking is a major stroke risk factor and increase the risk of heart stroke.

Many studies show that with mild and moderate drinking. the risk of ischemic stroke decreases due to decreased level of fibrinogen which helps in the formation of blood clots. However, heavy alcohol intake is associated with impaired fibrinolysis, increased platelet activation and increased BP and heart rate.

So in this case, patient’s history of alcoholism, coupled with his hypertension could be a causative factor of his current condition.

CASE: https://bejugamomnivasguptha.blogspot.com/2021/05/a-45-years-old-female-patient-with.html 

QUESTION: 1) What is the evolution of the symptomatology in this patient in terms of an event timeline and where is the anatomical localization for the problem and what is the primary aetiology of the patient's problem?

10 years back – episode of right and left upper limb paralysis

1 year back: right and left paresis due to hypokalaemia

8 months ago- bilateral pedal oedema, gradually progressing, present in both sitting and                                                            standing position, relieved on taking medication

7 months ago – diagnosed with infection in the blood

2 months ago – visited our hospital for neck pain and received medication

6 days ago – pain in the left upper limb, radiating along the upper limb, dragging type, nocturnal increase in the pain, aggravated during palpitations and relieved on medication

5 days ago –

palpitations, sudden in onset, more during night time, aggravated by lifting weights and speaking continuously, relieved by drinking more water, medication

dyspnoea during palpitation (NYHA CLASS 3)

chest pain associated with chest heaviness

the anatomical location is the cervical spine

the patient experienced episodes of palpitations, paresis, paralysis and oedema because of hypokalaemia

neck pain is due to cervical spondylosis

QUESTION:  What are the reasons for recurrence of hypokalaemia in her? Important risk factors for her hypokalaemia?

ANS) since the patient complains of oedema the drugs used to relieve it such as diuretics can cause hypokalaemia

The patient also no albumin which is a cause for both oedema and hypokalaemia

The risk factors include-

1.    Alcohol use(excessive)

2.    Chronic kidney disease

3.    Diabetic ketoacidosis

4.    Diuretics (water retention relievers)

5.    Excessive laxative use

6.    Folic acid deficiency

7.    Primary aldosteronism

8.    Some antibiotic use

QUESTION: What are the changes seen in ECG in case of hypokalaemia and associated symptoms?

ANS) The earliest electrocardiogram (ECG) change associated with hypokalaemia is a decrease in the T-wave amplitude. As potassium levels decline further, ST-segment depression and T-wave inversions are seen, while the PR interval can be prolonged along with an increase in the amplitude of the P wave. The U wave is described as a positive deflection after the T wave, often best seen in the mid-precordial leads





                                                                 

CASE: https://rishikoundinya.blogspot.com/2021/05/55years-old-patient-with-seizures.html 

QUESTION: Is there any relationship between occurrence of seizure to brain stroke. If yes, what is the mechanism behind it?

 -stroke is one of the most common cause of seizures in the elderly.

 post seizure stroke is of 2 types:

Early onset seizures have peak within 24 hours after stroke.

Late onset seizures occur after 2 week of stroke onset, peak within 6-12 months after the stroke, has a higher rate of recurrence

PATHOGENESIS OF SEIZURES FOLLOWING STROKE-

  There are several causes for early onset seizures after ischaemic strokes. An increase in intracellular Ca2+ and Na+ with a resultant lower threshold for depolarisation, glutamate excitotoxicity, hypoxia, metabolic dysfunction, global hypo perfusion, and hyper perfusion injury (particularly after carotid end arterectomy) have all been postulated as putative neurofunctional aetiologies. Seizures after haemorrhagic strokes are thought to be attributable to irritation caused by products of blood metabolism. The exact pathophysiology is unclear, but an associated ischaemic area secondary to haemorrhage is thought to play a part. Late onset seizures are associated with the persistent changes in neuronal excitability and gliotic scarring is most probably the underlying cause. Hemosiderin deposits are thought to cause irritability after a haemorrhagic stroke.In childhood, poststroke seizures can occur as part of perinatal birth trauma.

 

QUESTION: In the previous episodes of seizures, patient didn't lose his consciousness but in the recent episode he lost his consciousness what might be the reason?

The patient has a history of seizure activity, causing increased mechanical and chemical activity in the brain, which can lead to the development of organic lesions in the brain. The size of the lesion is directly proportional to the severity of the symptoms.

This patient has a history of recurrent seizures- 15 episodes in the last 5 years

There might be an aggravation of his symptoms during this episode when compared to the previous episodes. This severity could be the cause for his loss of consciousness.

QUESTION: What could have been the reason for the patient for developing ataxia in the past 1 year?

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4492805/

The patient has a history of alcohol consumption in excess the past three years. Excessive alcohol consumption is a risk factor for development of cerebellar dysfunction or cerebellar ataxia.

The alteration in GABAA receptor-dependent neurotransmission is a potential mechanism for ethanol-induced cerebellar dysfunction. Recent advances indicate ethanol-induced increases in GABA release are not only in Purkinje cells (PCs), but also in molecular layer interneurons and granule cells. Ethanol is shown to disrupt the molecular events at the mossy fiber – granule cell – Golgi cell (MGG) synaptic site and granule cell parallel fibers – PCs (GPP) synaptic site, which may be responsible for ethanol-induced cerebellar ataxia. Aging and ethanol may affect the smooth endoplasmic reticulum (SER) of PC dendrites and cause dendritic regression. Ethanol withdrawal causes mitochondrial damage and aberrant gene modifications in the cerebellum. The interaction between these events may result in neuronal degeneration, thereby contributing to motoric deficit. Ethanol activates double-stranded RNA (dsRNA)-activated protein kinase (PKR) and PKR activation is involved ethanol-induced neuroinflammation and neurotoxicity in the developing cerebellum. Ethanol alters the development of cerebellar circuitry following the loss of PCs, which could result in modifications of the structure and function of other brain regions that receive cerebellar inputs. Lastly, choline, an essential nutrient is evaluated for its potential protection against ethanol-induced cerebellar damages. Choline is shown to ameliorate ethanol-induced cerebellar dysfunction when given before ethanol exposure.

QUESTION: What was the reason for his IC bleed? Does alcoholism contribute to bleeding diathesis?

https://pubs.niaaa.nih.gov/publications/arh21-1/42.pdf

as mentioned this patient has a history of excessive alcohol consumption. Alcohol causes various hematological complications as described in the study above.

Bleeding diathesis is an unusual susceptibility to bleed (hemorrhage) mainly due to hypercoagulability. Heavy drinking can cause thrombocytopenia, as well as impact shape and functions of platelets. Impaired platelet function, together with reduced platelet count, can contribute to this condition associated with chronic alcoholism. This can also cause an increased incidence and recurrence of gastrointestinal hemorrhage associated with excessive alcohol intake

Another study conducted by Cambridge indicates, heavy drinkers have 1.6 more chance of intracerebral hemorrhage and a 1.8 increased chance of subarachnoid hemorrhage

QUESTION: Does the patient’s history of road traffic accident have any role in his present condition?

ANS: https://www.ahajournals.org/doi/pdf/10.1161/01.STR.14.4.617

The above study is similar to the case discussed where an accident occurring years ago has eventually led to an infarct.

Similarly, the accident that occurred in our patient 4 years ago can be the reason for his present condition.

QUESTION: What are warning signs of CVA?

  • Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body.
  • Sudden confusion, trouble speaking, or difficulty understanding speech.
  • Sudden trouble seeing in one or both eyes.
  • Sudden trouble walking, dizziness, loss of balance, or lack of coordination.
  • Sudden severe headache with no known cause.

QUESTION: What is the drug rationale in CVA?

1)thrombolysis- The NINDS rtPA Stroke Study compared the use of intravenous rtPA given within three hours after stroke onset versus placebo [21]. The rtPA-treated group showed a significant neurological improvement when compared to the untreated group.

Therapy with rtPA is given at a dose of 0.9 mg/kg IV without exceeding a maximum dose of 90 mg with 10% given as a loading bolus over 1 minute and the remainder as an infusion over 60 minutes. During the infusion and for one hour after concluding the infusion, the patient’s vital signs should be monitored and neurological assessment done every 15 minutes. Thereafter, observations should be carried out every 30 min for the next 6 hours and hourly afterward until 24 hours have transpired since treatment.

2)antiplatelet Therapy-Due to the thrombotic origin of AIS and the involvement of platelet aggregation in the development of said thrombus, antiplatelet drugs play an obvious and pivotal role in the medical treatment. Perhaps the most widely used antiplatelet agent is non-steroidal anti-inflammatory drugs (NSAID) acetylsalicylic acid (aspirin)

Aspirin at low doses binds and inhibits the platelet COX-1 irreversibly and consequently impairs the production of prostaglandins and thromboxane’s, noting thromboxane A2 (TXA2) in particular. The absence of TXA2 leads to the reduction in the TXA2-mediated amplification of platelet activation and thus hinders the platelet aggregation phenotype that includes morphological changes and expression of the fibrinogen receptor necessary for platelet aggregation.

3. Anticoagulant therapy

Anticoagulants are a heterogeneous group of pharmacological agents that by interacting with the coagulation cascade disrupt the formation of the fibrin mesh that forms the scaffold of the clot. When in homeostasis, the blood elements that participate in this process are kept at check thus preventing the formation of a blood clot in situ, or thrombus, inside the blood vessels.

QUESTION: What is myelopathy hand?

https://pubmed.ncbi.nlm.nih.gov/3818752/

https://online.boneandjoint.org.uk/doi/abs/10.1302/0301-620X.69B2.3818752

A characteristic dysfunction of the hand has been observed in various cervical spinal disorders. These are termed as myelopathy hand and appear to be due to pyramidal tract involvement. There is loss of power of adduction and extension of the ulnar fingers and inability to grip and release rapidly with these fingers.

 

QUESTION: What is finger escape?

finger escape sign is a component of WARTENBERG’S SIGN.

it is one of the signs in cervical cord damage particularly cervical myelopathy

When a patient holds fingers extended and adducted, the small finger spontaneously adducts indicating a weakness of intrinsic muscle. This commonly results from weakness of the ulnar nerve innervated intrinsic hand muscles.

 

QUESTION: What is Hoffman’s reflex?

Also known as DIGITAL reflex, SNAPPING reflex, JACOBSON’S reflex.

. It is used to examine the reflexes of upper extremities.

Hoffman’s reflex is a neurological examination finding elicited by a reflex test which can help verify the presence or absence of issues arising from the corticospinal tract.

Procedure: The Hoffmann's reflex test itself involves loosely holding the middle finger and flicking the fingernail downward, allowing the middle finger to flick upward reflexively. A positive response is seen when there is flexion and adduction of the thumb on the same hand

INTERPRETATION: If there is no movement in the index finger or thumb after this motion, the person has a negative Hoffman’s sign. If the index finger and thumb move, the person has a positive Hoffman’s sign.

A positive Hoffman sign indicates an upper motor neuron lesion and corticospinal pathway dysfunction likely due to cervical cord compression. (ex: CERVICAL MYELOPATHY)

However, a positive Hoffman sign can be present in an entirely normal patient. This happens in individuals who are hyper reflexive.

                                                                                 

CASE: https://neerajareddysingur.blogspot.com/2021/05/general-medicine-case-discussion.html?m=1

QUESTION:  What can be the cause of her condition?   

The patient’s GTCS episodes can be due to acute cortical vein thrombosis as seen in her MRI.

Seizures are the most common symptoms of CVT.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5771304/

this case report illustrates that CVT can occur in the setting of anaemia and thrombocytopenia. 

the above case is similar to our patient. Though neurological manifestations are not common in iron deficiency anaemia our patient presented with CVT. Also, our patient had thrombocytopenia which one would have expected to cause a bleeding tendency but paradoxically could have contributed to the development of the venous thrombosis as explained in the article above.

The associated symptoms such as headache and vomiting can be explained by the midline shift.

QUESTION:  What are the risk factors for cortical vein thrombosis?

·       -  birth control or excess oestrogen use.

·        - dehydration.

·         -ear, face, or neck infection.

·         -protein deficiencies.

·         -head trauma or injury.

·         -obesity.

·         -cancer.

·         -tumour.

 

QUESTION: There was seizure free period in between but again sudden episode of GTCS why? Resolved spontaneously why?      

The patient developed high grade fever (the patient had thrombophlebitis) with could have been the cause of the seizures. The decrease in the fever could have resolved the seizures.

QUESTION: What drug was used in suspicion of cortical venous sinus thrombosis?

The approach to treatment includes anticoagulation (intravenous heparin or subcutaneous low molecular weight heparin), thrombolysis (systemic or local), and symptomatic treatment (including antiepileptic therapy, lowering intracranial pressure, decompressive craniotomy)

CASE: https://muskaangoyal.blogspot.com/2021/05/a-78year-old-male-with-shortness-of.html

QUESTION:What is the difference btw heart failure with preserved ejection fraction and with reduced ejection fraction?

Ejection fraction is expressed as a percentage for measuring how much blood the left ventricle pumps out with each contraction.

-HF with reduced ejection fraction(HFrEF) is also known as systolic heart failure.

in this there is no adequate chamber dilatation as the heart muscle is unable to contract. Therefore, expels less oxygen rich blood into the body. Patients will have lower than normal left ventricular ejection fraction.

Causes: diabetes, valvular heart disease etc.

-HF with preserved ejection fraction(HFpEF) is also known as diastolic HF. In this the muscles of the heart contract normally and the heart pumps a normal amount of blood that enters it. There is heart muscle thickening which may cause the ventricle to hold small amount of blood. Therefore, the hearts output is normal but its limited capacity is inadequate to meet the body’s requirement.

Causes: hypertrophic cardiomyopathy, aortic stenosis, CAD, high blood pressure

 

QUESTION: Why haven't we done pericardiocenetis in this patient?  

Pericardiocenetis is a procedure done to remove fluid that has built up in the pericardium. This process requires a lot of precision as it can lead to a damage in the surrounding pleura. The patient has mild-moderate pericardial effusion, for which he was given symptomatic treatment rather than an invasive procedure like pericardiocenetis. The patient also has pleural effusion which can make the process difficult. Taking the patients state into account an invasive therapy that might cause damage was avoided.

 

QUESTION: What are the risk factors for development of heart failure in the patient?

The patient has the following risk factors:

the patient is a chronic alcoholic- 90ml/day for the last 30 years

chronic alcoholism is a major risk factor towards developing alcoholic cardiomyopathy.

The patient is a chronic smoker-30 years

Cigarette smoking can cause vascular changes and also directly effects the myocardium through increased oxidative stress and activated inflammatory pathways leading to systolic and diastolic dysfunction.

The patient is diabetic:

Diabetes can eventually cause damage to vessels and nerves supplying the heart along with having certain effects on myocardial structure and function increasing the risk of heart failure.

The patient has hypertension:

Hypertension increases the load on the heart muscles causing hypertrophy which can lead to a heart failure

The patient was diagnosed with first degree AV block

This is associated with increased risk of heart failure.

 

 

QUESTION: What could be the cause for hypotension in this patient?

 The patient is using a diuretic called LASIX and a hypertension drug telmasaratn, along with pericardial effusion. The fluid around the heart is effecting its pumping ability (decreased) along with this the diuretic and telmasartan are further causing a decrease in the pressure which has led to hypovolemia and thereby hypotension

Hypotension in this patient could be due to combination of pericardial effusion and use of diuretic LASIX.

The pumping ability of the heart in this patient is compromised, along with this he is on Diuretic and anti-hypertensive (Telma 40 mg), fluid restriction- all this might result in Hypovolemia and thereby Hypotension.

                                                                                                       

CASE: https://muskaangoyal.blogspot.com/2021/05/a-73-year-old-male-patient-with-pedal.html

QUESTION: What are the possible causes for heart failure in this patient?

the patient has various comorbidities which could have led to a heart failure

1.    The patient was diagnosed with type 2 diabetes mellitus 30 years ago and has been taking human mixtrad insulin daily and was also diagnosed with diabetic triopathy indicating uncontrolled diabetes which is major risk factor for heart failure

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5494155/

2.    The patient was also diagnosed with hypertension 19 yrs. ago which is also a risk factor for heart failure

https://pubmed.ncbi.nlm.nih.gov/31472888/

3.    He is a chronic alcoholic since 40 years which is a risk factor towards heart failure

https://www.nmcd-journal.com/article/S0939-4753(19)30360-6/fulltext

The findings in this article provide longitudinal evidence that moderate and heavy alcohol consumption are associated with decreased LVEF and trend towards a higher risk of incident LV systolic dysfunction, compared to light drinkers.

4.    The patient has elevated creatinine and AST/ALT ratios is >2 and was diagnosed with chronic kidney disease stage IV. CKD is also one of the risk factors for heart failure

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2900793/

 

QUESTION: what is the reason for anaemia in this case?

The patient has normocytic normochromic anaemia. it could be anaemia of a chronic disease as the patient is diagnosed with CKD stage IV.

Chronic kidney disease results in decreased production of erythropoietin which in turn decreases the production of red blood cells from the bone marrow.

Patient’s with anaemia and CKD also tend to have deficiency in nutrients like iron, vitamin B12 and folic acid essential in making healthy red blood cells

 

QUESTION: What is the reason for blebs and non-healing ulcer in the legs of this patient?

The most common cause for blebs and non-healing ulcer in this patient is diabetes mellitus. CKD is also known to cause delay in healing of wounds along with poorly controlled diabetes. Anaemia can also slow down the process of healing due to low oxygen levels.

                                                   

QUESTION: What sequence of stages of diabetes has been noted in this patient?

There are 4 stages in type 2 diabetes- insulin resistance, prediabetes, type 2 diabetes and type 2 diabetes and vascular complications, including retinopathy, nephropathy or neuropathy and, or, related microvascular events.

The patient is diagnosed with diabetic triopathy exhibiting sequence of neuropathy, retinopathy and nephropathy

The patient has been diagnosed with diabetic retinopathy, CKD stage IV and shows signs of diabetic neuropathy such as numbness

                                                                               

CASE: https://preityarlagadda.blogspot.com/2021/05/biatrial-thrombus-in-52yr-old-male.html

QUESTION: What is the evolution of the symptomology in this patient in terms of an event timeline and where is the anatomical localization for the problem and what is the primary etiology of the patient’s problem?

ANS. Timeline of the patient is as follows-

1 year ago

shortness of breath (Grade II- SOB on exertion); He visited the hospital where he was diagnosed to be hypertensive (on medication

2 days ago

Shortness of breath Grade II (on exertion) which progressed to Grade IV (at rest) for which he visited local RMP and was referred to our hospital. Patient also complains of decreased urine output since 2 days.

 

Present day

SOB grade IV (on rest) and anuria for the past one day.

 

Anatomical Location- the cardiac region.

Etiology- Congestive heart failure is a chronic progressive condition that affects the pumping power of the cardiac muscle. It occurs if the heart cannot pump (systolic) or fill (diastolic) adequately. Loss of atrial contraction and left atrial dilation in this case cause stasis of blood in the left atrium and may lead to thrombus formation in the left atrial appendage. This predisposes to stroke and other forms of systemic embolism.

QUESTION: What are the mechanism of action, indication and efficacy over placebo of each of the pharmacological and non-pharmacological interventions used for this patient?  

1)INJ. Dobutamine-

Mechanism of action- It is a synthetic catecholamine, that acts on B1, B2 and alpha 1 receptor.

Indications- It is a potent inotropic agent but only causes a slight increase in heart rate. It is given to patients with acute heart failure as iv infusion.

Efficacy: https://www.ncbi.nlm.nih.gov/books/NBK470431/

While the drug is safe, its use requires close monitoring as it has the potential to raise blood pressure and heart rate severely. Overall, the effects of dobutamine are short-lived. As soon as the infusion stops, the hemodynamic parameters will reverse.

 2)TAB. Digoxin-

Mechanism of action- It acts on the digitalis receptor and inhibits NA-K-ATPase, increasing cardiac output.

Indications- Digitalis is used in patients with low output failure especially when associated with atrial fibrillation, as indicated in this case.

 Efficacy: https://pubmed.ncbi.nlm.nih.gov/26913372/

3)INJ. Unfractionated Heparin 5000-

Mechanism of action- At low concentration, heparin selectively inhibits the conversion of prothrombin to thrombin, thus preventing thrombus formation. High dose heparin has antiplatelet action and prolongs bleeding time.

Indications- Patient had a biatrial thrombus and it was used to prevent further thrombus formation.

 Efficacy:https://pubmed.ncbi.nlm.nih.gov/2882339/

according to the study: Low-dose heparin appears to be effective, safe, well tolerated, and free from haemorrhagic risk for the prevention of myocardial reinfarction.

4)TAB. Carvedilol 3.125mg BD

Mechanism of action- It blocks B1, B2, Alpha 1 adrenergic receptors and no intrinsic sympathomimetic activity.

Indications- Used as a long term drug to reduce mortality in patients with congestive heart failure.

 

5)TAB. Acetyl cysteine 600mg PO TID

Mechanism of action- Acetyl cysteine is a sulfhydryl compound and acts to increase synthesis of glutathione in the liver. Glutathione subsequently acts as an antioxidant and facilitates conjugation to toxic metabolites, particularly the toxic metabolites of acetaminophen

6)TAB. Acitrom 2mg OD 

Mechanism of action- It is an anticoagulant that functions as a vitamin K antagonist.

Indications- oral anticoagulant which helps to prevent formation of harmful blood clots in the legs, lungs, brain and heart. It is used for deep vein thrombosis, pulmonary embolism and stroke prevention.

7)TAB. Cardivas 3.125mg PO/BD

Mechanism of action- It is carvedilol. It blocks B1, B2, Alpha 1 adrenergic receptors and no intrinsic sympathomimetic activity.

Indications- Used as a long term drug to reduce mortality in patients with congestive heart failure.

8)TAB. Dytor 10mg PO/OD

Mechanism of action- It is torsemide, a loop high ceiling diuretic. It acts on the thick ascending limb of the loop of Henle, increases Na, K and Cl excretion in the urine.

Indications- preferred in cases of hypertension associated with CCF and renal failure.

9)TAB Pan D 40mg PO/OD

Mechanism of action- It is a combination of domperidone and pantoprazole. It is a proton pump inhibitor and helps decrease acid production in the stomach.

Indications- used to treat gastroesophageal reflux disease (Acid reflux) and peptic ulcer disease by relieving the symptoms of acidity such as indigestion, heartburn, stomach pain, or irritation.

10)TAB. Taxim 200mg PO/OD

Mechanism of action- It is cefixime. They are beta-lactam antibiotics that inhibit synthesis of bacterial cell wall and produce a bactericidal effect.

Indications- Given mainly to prevent development of bacterial infections.

11)INJ. Thiamine 100mg in 50ml NS IV/TID

It is vitamin B1. It is naturally found in many foods in the human diet. In this case, the patient consumes excess alcohol- so he may get thiamine deficiency due to poor nutrition and lack of essential vitamins due to impaired ability of the body to absorb these vitamins.

12)INJ. HAI S.C 8U-8U-6U

Insulin given in this case to treat the patients DE novo diabetes mellitus.

 

QUESTION: What is the pathogenesis of renal involvement due to heart failure (cardio renal syndrome)? Which type of cardio renal syndrome is this patient? 

https://www.ahajournals.org/doi/full/10.1161/CIR.0000000000000664

Cardio renal syndrome encompasses a spectrum of disorders involving both the heart and kidneys in which acute or chronic dysfunction in 1 organ may induce acute or chronic dysfunction in the other organ. It represents the confluence of heart-kidney interactions across several interfaces. These include the hemodynamic cross-talk between the failing heart and the response of the kidneys and vice versa, as well as alterations in neurohormonal markers and inflammatory molecular signatures characteristic of its clinical phenotypes. There is immediate stress on the kidney through pathophysiological connections when CHF develops. The connectivity of the vascular bed, and its regulation by the sympathetic nervous system (SNS) and renin-angiotensin-aldosterone system (RAAS), continues the stress on the nephron. The long-term process results in scarring and fibrosis to both organs.

 CHF as a syndrome occurs due to the over expression of biologically active molecules that are capable of deleterious effects. The cells such as the myocardial myocytes, are capable of producing these potentially toxic effectors within close vicinity of the injury with the capacity for ongoing autocrine and paracrine activity. The spillover of this toxic milieu reaches the kidney, which has to regulate salt and water retention to compensate for loss of cardiac output. Finally, an important source of renal stress is increased cardiac preload.

The kidneys receive 25% of blood flow, where the majority goes to the cortex, which also has the greatest neural innervations to regulate changes acutely. The medulla receives only 10% of the blood supply. The renal microvascular bed however is continuous throughout. Thus, disease in any glomeruli could have implications when placed under supraphysiological stress from SNS or RAAS and matched with early disease in vascular endothelium and nitric oxide systems.

Compensation to ensure adequate GFR includes increased renal blood flow (afferent arteriolar vasodilatation), filtration pressure (via efferent arteriolar vasoconstriction) and glomerular hypertrophy, and hyper filtration (leads to scarring).

In this case the patient has Type 4 cardio renal syndrome: a chronic decline in kidney function that results in chronic cardiac dysfunction.

 

 QUESTION: What are the risk factors for atherosclerosis in this patient?

 

ANS. In this case, the risk factors for the development of atherosclerosis include:

-Patient has Diabetes mellitus type 2

 diabetes can accelerate atherosclerosis by driving inflammation and slowing down blood flow.

-Patient has history of alcohol abuse

 it can lead to atherosclerosis and increase the risk of stroke.

-Patient has a history of NSAID abuse

 which can change the vessels ability to relax and also stimulate growth of smooth muscle cells inside the arteries, thus leading to the clogging of the arteries.

-Patient also has a history of hypertension

 effect on the arterial wall also results in the aggravation and acceleration of atherosclerosis, particularly of the coronary and cerebral vessels. Moreover, hypertension appears to increase the susceptibility of the small and large arteries to atherosclerosis.

QUESTION: Why was the patient asked to get those APTT, INR tests for review?

ANS. APTT- Activated partial thromboplastin time; this is a blood test that characterizes coagulation of blood. The patient has a propensity for thrombus formation, which needs to be monitored by keeping check on the aPTT levels which is an indicator for the coagulability of the blood.

INR- It is international normalized ratio; it is also a measure of the ability of the blood to clot. This is an important test for patients who are on blood thinners (i.e.) anticoagulants. The patient in this case was taking heparin, so everyday reports of his INR value were needed.

                                                                                                  

CASE: https://daddalavineeshachowdary.blogspot.com/2021/05/67-year-old-patient-with-acute-coronary.html?m=1

 QUESTION: What is the evolution of the symptomatology in this patient in terms of an event timeline and where is the anatomical localization for the problem and what is the primary aetiology of the patient's problem?

 

TIMELINE OF EVENTS-

12 YEARS AGO

Diagnosed with diabetes and the patient is on medication ever since

ONE YEAR AGO

Heart burn like episodes since 1 year and relieved without medication

7 MONTHS AGO

Diagnosed with pulmonary TB completed full course of treated, presently sputum negative

6 MONTHS AGO

Diagnosed with hypertension, is on medication

HALF AN HOUR AGO

SOB since half an hour

 

Anatomical localisation - Cardiovascular system

Aetiology:  The patient is both Hypertensive and diabetic, both these conditions can cause Atherosclerosis: there is build-up of fatty and fibrous material inside the wall of arteries. (PLAQUE)

 

QUESTION: What are mechanism of action, indication and efficacy over placebo of each of the pharmacological and non-pharmacological interventions used for this patient?

 

Pharmacological interventions:

 

1)TAB MET XL 25 MG/STAT-

 contains Metoprolol as active ingredient

 MOA: METOPROLOL is a cardio selective beta blocker

 Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause your heart to beat more slowly (negative chronotropic effect)

and with less force (negative inotropic effect). Beta blockers also help open up your veins and arteries to improve blood flow.

Indications: it is used to treat Angina, High blood pressure and to lower the risk of heart attacks.

2)Non pharmacological intervention advised to this patient is: PERCUTANEOUS CORONARY INTERVENTION.

Percutaneous Coronary Intervention is a non-surgical procedure that uses a catheter (a thin flexible tube) to place a small structure called a stent to open up blood vessels in the heart that have been narrowed by plaque build-up (atherosclerosis).

 

QUESTION: What are the indications and contraindications for PCI?

     INDICATIONS:

- Acute ST-elevation myocardial infarction (STEMI)

- Non–ST-elevation acute coronary syndrome (NSTE-ACS)

-  Unstable angina.

-  Stable angina.

- Anginal equivalent (e.g., dyspnoea, arrhythmia, or dizziness or syncope)

-High risk stress test findings.

   CONTRAINDICATIONS:

-  Intolerance for oral antiplatelet long-term.

-Absence of cardiac surgery backup.

-Hypercoagulable state.

-High-grade chronic kidney disease.

-Chronic total occlusion of SVG.

-An artery with a diameter of <1.5 mm.

 

QUESTION: What happens if a PCI is performed in a patient who does not need it? What are the harms of overtreatment and why is research on over testing and overtreatment important to current healthcare systems?

 

Although PCI is generally a safe procedure, it might cause serious certain complications like 

A) Bleeding 

B) Blood vessel damage

C) Allergic reaction to the contrast dye used

D) Arrhythmias

E) Need for emergency coronary artery bypass grafting.

Because of all these complications it is better to avoid PCI in patients who do not require it.

Research on over testing and overtreatment is important as they can be more harmful than useful in many conditions. Such as:

Harms to patients

. Performing screening tests in patients with who at low risk for the disease which is being screened.

For example: Breast Cancer Screenings Can Cause More Harm Than Good in Women Who Are at Low Risk. A harmless lump or bump could incorrectly come up as cancer during routine breast screenings. This means that some women undergo surgery, chemotherapy or radiation for cancer that was never there in the first place.

. Overuse of imaging techniques such as X- RAYS AND CT SCANS as a part of routine investigations. 

 Overuse of imaging can lead to a diagnosis of a condition that would have otherwise remained irrelevant - OVER-DIAGNOSIS.

Also the adverse effects due to this are more when compared to the benefits.

. Over-diagnosis through over testing can psychologically harm the patient.

Hospitalisations for those with chronic conditions who could be treated as outpatients [ can lead to economic burden and a feeling of isolation.

Harm to health care systems

The use of expensive technologies and machineries are causing economic burden on health care systems.

                                                                                           

CASE: https://bhavaniv.blogspot.com/2021/05/case-discussion-on-myocardial-infarction.html?m=1

 QUESTION: What is the evolution of the symptomatology in this patient in terms of an event timeline and where is the anatomical localization for the problem and what is the primary etiology of the patient's problem?

 

3 days ago

Developed chest pain on the right side of the chest.

 

Anatomical Localization: Cardiovascular system – Occlusion of the right coronary artery.

Etiology:

Atherosclerosis – Also known as coronary artery disease, this condition is the most common cause of heart attacks and occurs when the buildup of fat, cholesterol, and other substances forms plaque on the walls of the coronary arteries

Coronary artery spasm – A rare cause of blockage, spasms of the coronary arteries can cause them to become temporarily constricted. 

Coronary artery tear – Also known as a spontaneous coronary artery dissection, a tear in a coronary artery can prevent blood from reaching the heart and cause a heart attack.

 

QUESTION: What are mechanism of action, indication and efficacy over placebo of each of the pharmacological and non pharmacological interventions used for this patient?

 

TAB. ASPIRIN 325 mg PO/STAT

-MECHANISM OF ACTION- Aspirin is a NSAID. They inhibit COX-1 and COX-2 thus decreasing the prostaglandin level and thromboxane synthesis.

-Indications- They are anti platelet medications and, in this case, used to prevent formation of blood clots in blood vessels.

-Efficacy over Placebo: According to the study, there was a clear reduction in some serious cardiovascular adverse events.  Aspirin use was associated with a lower risk of myocardial infarction than placebo use or no treatment (risk ratio [RR], 0.83, 95% confidence interval [CI]: 0.73–0.95, P = 0.005).

 

TAB ATORVAS 80mg PO/STAT

--MECHANISM OF ACTION: Atorvastatin is a statin medication and a competitive inhibitor of the enzyme HMG-CoA reductase, which catalyzes the conversion of HMG-CoA to mevalonate, an early rate-limiting step in cholesterol biosynthesis. Atorvastatin acts primarily in the liver, where decreased hepatic cholesterol concentrations stimulate the upregulation of hepatic low-density lipoprotein receptors, which increases hepatic uptake of LDL. Atorvastatin also reduces Very-Low-Density Lipoprotein-Cholesterol, serum triglycerides and Intermediate Density, but increases High-Density Lipoprotein Cholesterol. In vitro and in vivo animal studies also demonstrate that atorvastatin exerts protective effects independent of its lipid-lowering properties, also known as the pleiotropic effects of statins. These effects include improvement in endothelial function, enhanced stability of atherosclerotic plaques, reduced oxidative stress and inflammation, and inhibition of the thrombogenic response. Statins were also found to bind allosterically to β2 integrin function-associated antigen-1, which plays an essential role in leukocyte movement and T cell activation.

-Indication: Atorvastatin is indicated for the treatment of several types of dyslipidemias. Dyslipidemia describes an elevation of plasma cholesterol, triglycerides or both as well as to the presence of low levels of high-density lipoprotein. This condition represents an increased risk for the development of atherosclerosis. Atorvastatin is indicated, in combination with dietary modifications, to prevent cardiovascular events in patients with cardiac risk factors and/or abnormal lipid profiles. Atorvastatin can be used as a preventive agent for myocardial infarction, stroke, and angina, in patients without coronary heart disease but with multiple risk factors and in patients with type 2 diabetes without coronary heart disease but multiple risk factors. Atorvastatin may be used as a preventive agent for non-fatal myocardial infarction, fatal and non-fatal stroke, revascularization procedures, hospitalization for congestive heart failure and angina in patients with coronary heart disease.

-Efficacy over Placebo: Out of 18 studies done, statins were shown to help in 16 studies. The studies show a 27% reduction in the onset of MI.

               TAB CLOPIBB 300mg PO/STAT

-MECHANISM OF ACTION- Clopidogrel is metabolized to its active form by carboxylesterase-1.3 The active form is a platelet inhibitor that irreversibly binds to P2Y12 ADP receptors on platelets. This binding prevents ADP binding to P2Y12 receptors, activation of the glycoprotein GPIIb/IIIa complex, and platelet aggregation.

-Indications- Clopidogrel is indicated to reduce the risk of myocardial infarction for patients with non-ST elevated acute coronary syndrome, patients with ST-elevated myocardial infarction, and in recent MI, stroke, or established peripheral arterial disease.   


QUESTION:  Did the secondary PTCA do any good to the patient or was it unnecessary?

- PTCA is known to improve the patient’s vessel patency if it is done within 4 hours of the symptom onset or if it is used as adjunctive therapy along with some systemic thrombolytic therapy. It can restore up to 90% of the vessel’s natural state if implemented within enough time.

-Though there are certain benefits from PTCA, there are some disadvantages too. If done along with systemic thrombolytics then it can lead to a higher incidence of bleeding complications. Just PTCA alone, has not proven to show any ventricular function improvement or decreased mortality.

                                                                   

CASE: https://kattekolasathwik.blogspot.com/2021/05/a-case-of-cardiogenic-shock.h

 QUESTION: How did the patient get relieved from his shortness of breath after i.v fluids administration by rural medical practitioner?

- Rapid breathing along with other presentations like cold, clammy extremities is an indicator of cardiogenic shock.

-In cardiogenic shock, there is hypovolemia, which will reduce perfusion to major organs in the body. when there is decreased perfusion, the body slows starts shutting down. To halt this process, iv fluids are given rapidly to continue the perfusion of fluids at the normal rate.

-When this patient was given fluids, the perfusion returns to normal which helps abate the shortness of breath.

 

QUESTION: What is the rationale of using torsemide in this patient?

- In patients who have cardio renal syndrome, there is a renal dysfunction along with cardiac abnormalities. In such patients there is a volume overload and heart failure, the combination of increased pulmonary artery or central venous pressure with low systemic pressure may lead to a severe compromise of the net renal perfusion pressure.

- Furosemide is a commonly used diuretic to treat volume overload state in heart failure, yet it is particularly prone to the problem of diuretic resistance because of its particular pharmacokinetics. 

Unfortunately, chronic diuretic use also induces hypertrophy in distal tubular cells, leading again to enhanced sodium reuptake, contributing further to diuretic resistance. Alternatives to furosemide, such as torsemide, have been shown to have a slight advantage in selected studies because of somewhat more favorable pharmacokinetics.

 

 

QUESTION: Was the rationale for administration of ceftriaxone? Was it prophylactic or for the treatment of UTI?

- Patients with cardio renal syndrome are known to have systemic inflammation which can be drawn parallel to end stage kidney disease. Here there is an inflammation of monocytes and other inflammatory cells. This puts the patient in an immune suppressive state.

-Due to this state, do reduce the chances of infection, as a prophylactic measure, ceftriaxone might have been started.

CASE: https://63konakanchihyndavi.blogspot.com/2021/05/case-discussion-on-pancreatitis-with.html

QUESTION: What is the evolution of the symptomatology in this patient in terms of an event timeline and where is the anatomical localization for the problem and what is the primary aetiology of the patient's problem?

 

TIMELINE OF THE PATIENT:

 

5YEARS AGO

An episode of pain abdomen and vomiting. Treated conservatively at a local hospital. Stopped alcohol consumption. Symptom free for almost 3 YEARS

. Patient started consuming alcohol, this lead to recurrent episodes of pain abdomen and vomiting.

 

1 YEAR AGO

 5-6 episodes of pain abdomen and vomiting. Treated by a RMP.

 

 

1 WEEK AGO

Binge of alcohol, following this he had pain abdomen and vomiting 

SINCE 4 DAYS

High grade fever with chills and rigors. Developed constipation

Burning MICTURITION associated with suprapubic pain, increased frequency and urgency.

 

 

 

Anatomical localisation- GASTROINTESTINAL SYSTEM. (stomach and pancreas)

  Aetiology:  the patient is a chronic alcoholic, episodes of abdominal pain and vomiting are following alcohol consumption. therefore, it is heavy drinking that has led to the above condition in the patient.

 

QUESTION: What is the efficacy of drugs used along with other non-pharmacological treatment modalities and how would you approach this patient as a treating physician?

 

Drugs used in this patient -

1) ING. MEROPENEM; TID for 7 days

. Meropenem is a broad spectrum carbipenem antibiotic used to treat abdominal and skin infections.

Mechanism of action: Meropenem is bactericidal except against Listeria monocytogenes, where it is bacteriostatic. It inhibits bacterial cell wall synthesis like other β-lactam antibiotics. In contrast to other beta-lactams, it is highly resistant to degradation by β-lactamases or cephalosporinases.

BASED ON A STUDY-In patients with moderate to severe intra-abdominal infections, empirical monotherapy with meropenem achieved clinical response rates ranging from 91 to 100% in 7 randomised comparative trials. Meropenem also achieved clinical response rates of over 80% in patients with severe intra-abdominal infections. 

 

2) ING. METROGYL 500 mg IV TID for 5 days

 Composition- METRONIDAZOLE.

. Metronidazole belongs to Nitro imidazole group of antibiotics, is used to treat gastrointestinal infections, skin and blood infections.

Mechanism of action: Metronidazole diffuses into the organism, inhibits protein synthesis by interacting with DNA and causing a loss of helical DNA structure and strand breakage. Therefore, it causes cell death in susceptible organisms.

Optimal Treatment for Complicated Intra-abdominal Infections ...https://www.ncbi.nlm.nih.gov › articles › PMC5047423

Based on the above study metronidazole when combined with another antimicrobial agent is more effective in the treatment of complicated intra-abdominal infections (particularly those caused by ENTEROBACTERIACEAE MEMBERS as they are resistant to carbipenem).

 

3) ING. AMIKACIN 500 mg IV BD for 5days

. AMIKACIN is an amino glycoside antibiotic used in the treatment of serious bacterial infections.

Mechanism of action: The primary mechanism of action of amikacin is the same as that for all aminoglycosides. It binds to bacterial 30S ribosomal subunits and interferes with mRNA binding and tRNA acceptor sites, interfering with bacterial growth.

 

All the above three antibiotics are given to control infection and prevent sepsis in the patient.

 

4) ING. OCTREOTIDE 100 mg SC, BD

Octreotide is a long acting analogue of Somatostatin

. It inhibits exocrine secretion of the pancreas, also has anti-inflammatory and cytoprotective effects. 

Mechanism of action:  octreotide decreases the release of growth stimulating hormones, decreases blood flow to the digestive organs, and inhibits the release of digestive hormones such as serotonin, gastrin, vasoactive intestinal peptide, secretin, motilin, and pancreatic polypeptide

EFFICACY - Octeotride based on several studies did not provide any symptomatic relief or better cure when compared to other drugs. However, it played a significant role in reducing SERUM AMYLASE AND LIPASE LEVELS.

 

5) ING. PANTOP 40 mg IV, OD

. Pantoprazole a proton pump inhibitor, is known to have pancreatic anti secretory effect.

. Oxidative stress is common in acute pancreatitis- Pantoprazole has an inhibitory effect on hydroxyl radicals (free radicals)- thereby reduces the progression of the disease and helps in reducing oxidative stress.

 . PPZ treatment also reduces tissue infiltration of inflammatory cells and acinar cell necrosis in severe AP.

 

6) ING. TRAMADOL in 100 ml NS IV, OD

Tramadol is an opioid analgesic used to relieve severe pain in acute pancreatitis.

Mechanism of action: Tramadol is a centrally acting analgesic with a multimode of action. It acts on serotonergic and noradrenergic nociception, while its metabolite O-desmethyltramadol acts on the µ-opioid receptor. Its analgesic potency is claimed to be about one tenth that of morphine.

 

7)ING. THIAMINE 100 mg in 100 ml NS IV, TID* 

. Thiamine -  Vitamin B1 supplement.

. As the patient is on TPN there is a chance of B1 deficiency

. Wernicke’s encephalopathy (due to B1 deficiency) has been noted in several cases of pancreatitis so to prevent this Thiamine is given as a prophylactic measure

 

8) TPN (Total Parenteral Nutrition)

 (TPN) is a method of feeding that bypasses the gastrointestinal tract. Fluids are given intravenously to provide nutrients the body needs. The method is used when a person cannot or should not receive feedings or fluids by mouth.

Parenteral nutrition is used to prevent malnutrition in patients who are unable to obtain adequate nutrients by oral or enteral routes.

 

 9) IV NS / RL at the rate 12l ml per hour

 

MY APPROACH TO THIS PATIENT AS A TREATING PHYSICIAN:

-When the patients present with the complaints of pain abdomen and vomiting, along with fever, burning micturition, certain investigations must be done.

- First, a general examination must be done, including inspection, percussion, palpation and auscultation of the abdomen. 

-Other investigations are CBP (Complete Blood Picture), LFT (Liver Function tests), RFT (Renal Function Test), Urine analysis, Serum amylase, ABG (Arterial Blood Gas), Pleural tapping.

-Some imaging studies like, contrast enhanced CT and chest x-ray should be taken as well.

-Now depending on the diagnosis based on the results, chemotherapy must be started. In the case of pancreatitis in this patient, the following treatment can be given. 

-- Antibiotic like MEROPENAM, METROGYL, AMIKACIN

-- Fluid levels should be maintained with RL or NS

--Somatostatin analogue like SOMATOSTATIN, decreases the exocrine secretion in the pancreas

-- Proton pump inhibitor

--Vitamins such as Thiamine

--Anti-analgesic such as TRAMADOL

QUESTION: What is causing the patient's dyspnoea? How is it related to pancreatitis?

Pancreatitis is associated with shortness of breath( https://www.mayoclinic.org/diseases-conditions/pancreatitis/symptoms-causes/syc-20360227#:~:text=Breathing%20problems.,fall%20to%20dangerously%20low%20levels )

Acute pancreatitis is associated with release of inflammatory factors which the lungs, fluid accumulation which is also associated with pancreatitis (the patient was diagnosed pleural effusion) results in shortness of breath.

QUESTION:  Name possible reasons why the patient has developed a state of hyperglycaemia.

1.    Pancreatitis damages cells that produce insulin and glucagon which are hormones that control the levels of blood sugar. Insufficiency of these hormones can lead to hyperglycaemia

2.    Patient is a known alcoholic with increased consumption since 2 months (2 litres of toddy everyday) which could also be a cause of diabetes in the patient. But the patient was never tested before he came to our OPD and did not recall any notable signs.

 

QUESTION:  What is the reason for his elevated LFTs? Is there a specific marker for Alcoholic Fatty Liver disease?

Excess alcohol consumption is known to elevate LFT’s. alcohol is a known hepatotoxin which effects liver functioning and there is no certain linear relation between the amount consumed and the stage of liver damage.

CASE: https://chennabhavana.blogspot.com/2021/05/general-medicine-case-discussion-1.html

QUESTION: What is the most probable diagnosis in this patient?

-Differential Diagnosis:

a)    Ruptured Liver Abscess.

b)    Organized Intraperitoneal Hematoma.

c)    Organized collection secondary to Hollow Viscous Perforation.

d)    Free fluid with internal echoes in Bilateral in the Sub diaphragmatic space.

e)    Grade 3 RPD of right Kidney

-The most probably diagnosis is there is abdominal hemorrhage. This will give reasoning to the abdominal distention, and the blood which is aspirated.

QUESTION: What was the cause of her death?

-After getting discharged from the hospital, the patient went to Hyderabad and underwent an emergency laparotomy surgery. The patient passed away the next day. Cause of her death can be due to complications of laparotomy surgery such as, hemorrhage (bleeding), infection, or damage to internal organs.

QUESTION:  Does her NSAID abuse have something to do with her condition? How? 

-NSAID-induced renal dysfunction has a wide spectrum of negative effects, including decreased glomerular perfusion, decreased glomerular filtration rate, and acute renal failure. Chronic NSAIDs use has also been related to hepatotoxicity. While the major adverse effects of NSAIDs such as gastrointestinal mucosa injury are well known, NSAIDs have also been associated with hepatic side effects ranging from asymptomatic elevations in serum aminotransferase levels and hepatitis with jaundice to fulminant liver failure and death.

  QUESTION: What could be the reason for his SOB?

This patient underwent a TURP around two months ago, post which he came back to the hospital with Hyponatremia, and elevated creatinine levels (5.2 mg/dl). These were both corrected and he was discharged.

After discharge, he came for routine testing about 1 week later, with elevated creatinine levels (6.2 mg/dl), and then presented to the hospital with SOB on exertion with a serum creatinine level raised to 10 mg/dl.

The increased creatinine levels are known to cause shortness of breath.

 QUESTION: Why does he have intermittent episodes of drowsiness?

In this case, post TURP in the patient he presented to the hospital with drowsiness and excessive sleep that attenders felt difficult to wake him up from sleep and attenders were regularly monitoring his BP, which was found to be fluctuating and patient was brought to the hospital. The patient was diagnosed with hyponatremia. The common symptoms of hyponatremia related to this case are- headache, confusion, loss of energy, drowsiness and fatigue. This could have been the cause for drowsiness.

QUESTION:  Why did he complaint of fleshy mass like passage in his urine?

 The patient in this case has a history of dysuria and urine is cloudy in appearance. On investigation, there is a presence of pus cells in the urine. The patient has an indication of hydronephrosis, which is a condition that typically occurs when the kidney swells due to urine failing to properly drain from the kidney to the bladder. Due to stasis of fluid, these patients become predisposed to development of urinary tract infection (UTI), which can be the cause of fleshy type masses or gritty particles in the urine.

QUESTION: What are the complications of TURP that he may have had?

ANS. Some possible complications may include:

a)    Bladder injury

b)    Bleeding

c)     Blood in the urine after surgery

d)    Electrolyte abnormalities

e)    Infection

f)      Painful or difficult urination

g)    Retrograde ejaculation (when ejaculate goes into the bladder and not out the penis)

CASE: https://drsaranyaroshni.blogspot.com/2021/05/an-eight-year-old-with-frequent.htm

QUESTION: Why is the child excessively hyperactive without much of social etiquettes?

ANS. According to the case history, the patient, in this case an 8-year-old boy, is excessively hyperactive, impulsive, does not have proper social etiquettes as is expected of his age, too active to pay any attention at school, talk so fast that even comprehending sentences becomes quite difficult. These issues are ongoing in the boy, and are prominent enough to be negatively affecting his daily life. This indicates towards the boy possibly having ADHD (attention deficit hyperactivity disorder), a mental health disorder that can cause above-normal levels of hyperactive and impulsive behaviors. People with ADHD may also have trouble focusing their attention on a single task or sitting still for long periods of time.

People who have ADHD present with the combination of these symptoms:

a)    Overlook or miss details, make careless mistakes in schoolwork, at work, or during other activities

b)    Have problems sustaining attention in tasks or play, including conversations, lectures, or lengthy reading

c)    Seem to not listen when spoken to directly

d)    Fail to not follow through on instructions, fail to finish schoolwork, chores, or duties in the workplace, or start tasks but quickly lose focus and get easily sidetracked

e)    Avoid or dislike tasks that require sustained mental effort, such as schoolwork or homework.

f)     Lose things necessary for tasks or activities, such as school supplies, pencils, books, tools, wallets, keys, paperwork, eyeglasses, and cell phones

g)   (Reference link- https://www.nimh.nih.gov/health/publications/attention-deficit-hyperactivity-disorder-adhd-the-basics/)

Before ADHD is made as a proper diagnosis, these activities can often be interpreted as the child being hyperactive, out of control, and lacking in social etiquette.

QUESTION: Why doesn't the child have the excessive urge of urination at night time?

ANS. The child in this case has gotten a series of tests done in order to come to a conclusion about his diagnosis.

a)    They have done a complete urine exam, a urine culture and sensitivity test, and checked levels of serum electrolyte and they were normal.

b)    From the history of excessive hyperactivity, impulsiveness, lacking of attentivity, a thought goes towards Attention Deficit Hyperactivity Disorder (ADHD) and in turn towards the association urination disorders. Studies indicate that children with ADHD have a higher tendency to lack bladder control, and are prompted to go to the bathroom more frequently.

c)    Since the child does not get the urgency to urinate when he is asleep, there can be a chance of the manifestation being psychosomatic, or as a result of an undiagnosed anxiety disorder, or a stressor triggering this manifestation.

When you feel anxious, your body’s fear response can be triggered, overwhelming your bladder’s mechanisms for retaining urine, causing you to want to urinate. The child may be free from the triggers while asleep, especially because he does not have a history of nocturnal enuresis, thus enabling him to sleep well through the night.

 

 

QUESTION: How would you want to manage the patient to relieve him of his symptoms?

ANS. The diagnosis of the child is leaning towards the possibility of a psychosomatic overactive bladder, which can be triggered by various stressors or the possibility of the child having undiagnosed ADHD, a conclusion based on history of his behavior. In either of these cases, change in the daily habits and behavior, along with conservative therapy such as bladder exercises can go a long way before doing medical or surgical intervention.

      -The most common treatment options include bladder retraining and pelvic floor exercises.

-          Bladder retraining involves putting the child on a “voiding schedule” where they go to the restroom to urinate on a schedule. This helps to slowly train the bladder to hold more and more urine, as it is designed to.

-          Pelvic floor exercises provide a way to strengthen the muscles that are used to slow and stop the flow of urine and prevent wetting.

If the above methods do not work drugs like oxybutynin can help in controlling an overactive bladder.

QUESTION: Which clinical history and physical findings are characteristic of tracheoesophageal fistula?

-In adults, the characteristic history is recurrent pneumonia, hemoptysis, and coughing after eating.

- In children, the features found in cases of congenital tracheoesophageal fistula are- there is frothy, white bubbles in the mouth, coughing or choking when feeding, vomiting, blue color of the skin (cyanosis), especially when the baby is feeding, difficulty breathing.

- The physical findings are, in the presence of TEF, abdominal distention may occur secondary to collection of air in the stomach.

 

QUESTION: What are the chances of this patient developing immune reconstitution inflammatory syndrome? Can we prevent it? 

- Immune reconstitution inflammatory syndrome (IRIS) is a condition seen in some cases of AIDS or immunosuppression, in which the immune system begins to recover, but then responds to a previously acquired opportunistic infection with an overwhelming inflammatory response that paradoxically makes the symptoms of infection worse.

-There are chances that this patient can develop IRIS due to the patient being RVD positive. She is more susceptible to any infection and therefor prone to reinfection. To prevent IRIS, the most effective method is to involve the initiation of ART before immunosuppression is advanced. IRIS is uncommon in individuals who initiate antiretroviral treatment with a CD4+ T-cell count greater than 100 cells/uL. Aggressive efforts should be made to detect asymptomatic mycobacterial or cryptococcal disease prior to the initiation of ART, especially in areas endemic for these pathogens and with CD4 T-cell counts less than 100 cells/uL.

                                                                                       

INFECTIOUS DISEASE AND HEPATOLOGY

CASE: https://kavyasamudrala.blogspot.com/2021/05/liver-abscess.html

 QUESTION:  Do you think drinking locally made alcohol caused liver abscess in this patient due to predisposing factors present in it? What could be the cause in this patient?

 

Patient is toddy drinker since 30 years and by occupation he is a palm tree climber. Toddy is locally fermented beverage and can be contaminated with various organisms. The organism that is known to cause liver abscess is enatamoeba histolytica. The patient belongs to the low socio-economic group and is malnourished which favours the survival of the parasite

 

QUESTION: What is the etiopathogenesis of liver abscess in a chronic alcoholic patient? (since 30 years - 1 bottle per day)

 

Alcohol causes AMOEBIC LIVER ABSCESS(ALA) through a multitude of mechanisms:

a)    Alcohol induced hepatic dysfunction

b)    It lowers body resistance and suppresses immune mechanisms in the habitual consumers.

c)     Locally prepared alcohol (toddy) when brewed in unhygienic conditions may be contaminated by pathogens (bacteria, parasites- ENTAMOEBA HISTOLYTICA.)

d)    Toddy has very less alcoholic content (< 5%) - this favours the survival of Entamoeba and promotes the conversion of latent forms to virulent forms resulting in more symptomatic cases.

alcohol-induced hepatic dysfunction and possible suppression of amoebistatic immune mechanisms by substances in the beverages could also be attributed in the mechanism

 

QUESTION: Is liver abscess more common in right lobe?

Liver abscess is more common in right lobe than left lobe. The ratio is 2:1.

 Liver abscess is more common in the right lobe than left lobe because

a)    The right hepatic lobe receives blood from both the superior mesenteric and portal veins, whereas the left hepatic lobe receives inferior mesenteric and splenic drainage

b)    It also contains a denser network of biliary canaliculi and overall more hepatic mass.

 

QUESTION: What are the indications for ultrasound guided aspiration of liver abscess?

 Indications for aspiration of a liver abscess include the following:

a)    Presence of a left lobe abscess of more than 10cm in diameter. 

b)    Pain and impending rupture.

c)     Abscess that does not respond to medical treatment within 3-5 days. 

                                                                                                                            


CASE: https://63konakanchihyndavi.blogspot.com/2021/05/case-discussion-on-liver-abcess.html

QUESTION: Cause of liver abscess in this patient?

Patient is an occasional Toddy drinker. Toddy when collected in unhygienic environment, might get contaminated with pathogens such as bacteria, parasites (Entamoeba histolytica).

These pathogens though portal circulation reach the liver and might result in ABSCESS formation in the patient.

 

QUESTION: How do you approach this patient?

 

. When patient presents with chief complaints of abdominal pain, fever -

1.    Detailed history regarding each of the symptom should be taken.

2.    General examination to know the overall health status should be carried out.

3.    Following general examination, systemic examination (CVS, RESPIRATORY, PER ABDOMEN, CNS) should be done.

       Patient’s symptoms point out to the involvement of GASTROINTESTINAL SYSTEM, therefore special emphasis should be on per abdominal examination.

 4. Through history and examination, we arrive at provisional diagnosis.

 5. To confirm the diagnosis, investigations, imaging tests should be taken.

 6. For this patient based on his symptomatology, the following investigations should be done.

       CBP, LIVER FUNCTION TESTS, RENAL FUNCTION TESTS, URINE ANALYSIS.

 7. Imaging tests- CXR, USG abdomen.

  Based on the results of these the diagnosis can be confirmed; treatment can be initiated.

 

This patient is diagnosed with LIVER ABSCESS (by the above approach), the following treatment can be given.

. In practice an empirical treatment is given to treat both amoebic and pyogenic liver abscess -

  This includes use of Broad spectrum antibiotics (for pyogenic liver abscess), Metronidazole (for amoebic liver abscess)

. Analgesics and anti inflammatory drugs -to relieve pain and fever.

. Multivitamin supplements

. Saline infusion- to maintain fluid levels. 

All the above medicines should be given for 7- 10 days.

 

Following this review, the patient and see if there is any improvement.

USG abdomen should be done se if the abscess is resolving.

Investigations (CBP, LFT, RFT) should be done to check for the improvement.

If the abscess did not resolve ULTRASOUND GUIDED ASPIRATION SHOULD BE DONE.

    

 

QUESTION: Why do we treat here; both amoebic and pyogenic liver Abscess? 

 The presentation for both amoebic, pyogenic liver abscess is the same I.e, pain abdomen, fever, constitutional symptoms like nausea and vomiting, loss of appetite, in some cases there may be pulmonary symptoms.

INVESTIGATIONS-

There is leucocytosis, elevated alkaline phosphatase, ALT, AST  

USG-a hypo echoic mass for both type of abscess.

Amoebic and pyogenic liver abscess can be differentiated only by culture and sensitivity of the aspirate obtained by USG GUIDED ASPIRATION OF THE ABSCESS.

USG GUIDED ASPIRATION has the following risk factors associated with it:

1) if abscess is thin walled there is a risk of rupture.

2)if abscess is on the posterior aspect of the liver, it will not be accessible.

3)there is also a risk of bleeding.

. Blood culture taken prior to the administration of antibiotics is helpful for identifying the causative organism but as this patient had already taken antimicrobials before he came to the hospital, there is severe abdominal pain treatment is started immediately without a blood culture report.

Considering that it is difficult to distinguish amoebic liver abscess from pyogenic liver abscess,

We treat both forms of Liver abscess empirically using-

·         Broad spectrum antibiotics- a combination of penicillin, cephalosporin, ahminoglycosides

·         Metronidazole- has both antibacterial and antiprotozoal activity.

Liver abscess: diagnostic and management issues found in ...https://academic.oup.com › bmb › article

This article highlights the difficulties in distinguish the two forms of liver abscess.

 

 

QUESTION: Is there a way to confirm the definitive diagnosis in this patient?

Liver abscess can be confirmed by USG ABDOMEN - it presents as single / multiple, round / oval, hypoechoic - hyper echoic mass more commonly is the right lobe of the liver.

However, USG cannot differentiate an amoebic liver abscess from pyogenic liver abscess.

For this 

·         Blood culture 

·         USG guided aspiration of the abscess should be done.

This aspirate should be subjected to antigen testing for –

  Subjected to microbiological culture and sensitivity - to identify pyogenic organisms.

                                  

INFECTIOUS DISEASE (MUCORMYCOSIS)

CASE: https://manikaraovinay.blogspot.com/2021/05/50male-came-in-altered-sensorium.html

 QUESTION:  What is the evolution of the symptomatology in this patient in terms of an event timeline and where is the anatomical localization for the problem and what is the primary aetiology of the patient's problem?

1.    3 years ago- diagnosed with hypertension

2.    21 days ago- received vaccination at local PHC which was followed by fever associated with chills and rigors, high grade fever, no diurnal variation which was relieved on medication

3.    18 days ago- complained of similar events and went to the the local hospital, it was not subsided upon taking medication(antipyretics)

4.    11 days ago - c/o Generalized weakness and facial puffiness and periorbital oedema. Patient was in a drowsy state

5.    4 days ago-  

a.    patient presented to casualty in altered state with facial puffiness and periorbital oedema and weakness of right upper limb and lower limb

b.    towards the evening patient periorbital oedema progressed

c.    serous discharge from the left eye that was blood tinged

d.    was diagnosed with diabetes mellitus

6.    patient was referred to a government general hospital

7.    patient died 2 days ago

 

patient was diagnosed with diabetic ketoacidosis and was unaware that he was diabetic until then. This resulted in poorly controlled blood sugar levels. The patient was diagnosed with acute oro rhino orbital mucormycosis . rhino cerebral mucormycosis is the most common form of this fungus that occurs in people with uncontrolled diabetes ( https://www.cdc.gov/fungal/diseases/mucormycosis/definition.html ) the fungus enters the sinuses from the environment and then the brain.

The patient was also diagnosed with acute infarct in the left frontal and temporal lobe. Mucormycosis is associated with the occurrence of CVA ( https://journal.chestnet.org/article/S0012-3692(19)33482-8/fulltext#:~:text=There%20are%20few%20incidences%20reported,to%20better%20morbidity%2Fmortality%20outcomes. )

 

QUESTION:  What is the efficacy of drugs used along with other non-pharmacological treatment modalities and how would you approach this patient as a treating physician?

The proposed management of the patient was –

1.    inj. Liposomal amphotericin B according to creatinine clearance

2.    200mg Iitraconazole was given as it was the only available drug which was adjusted to his creatinine clearance

3.    Deoxycholate was the required drug which was unavailable

https://pubmed.ncbi.nlm.nih.gov/23729001/ this article talks about the efficacy and toxicity of different formulations of amphotericin B

along with the above mentioned treatment for the patient managing others symptoms is also done by-

     I.        Management of diabetic ketoacidosis –

(a)  Fluid replacement-  The fluids will replace those lost through excessive urination, as well as help dilute the excess sugar in blood.

(b)  Electrolyte replacement-The absence of insulin can lower the level of several electrolytes in blood. Patient will receive electrolytes through a vein to help keep the heart, muscles and nerve cells functioning normally.

(c)  Insulin therapy-  Insulin reverses the processes that cause diabetic ketoacidosis. In addition to fluids and electrolytes, patient will receive insulin therapy

QUESTION:  What are the postulated reasons for a sudden apparent rise in the incidence of mucormycosis in India at this point of time? 

 Mucormycosis is may be being triggered by the use of steroids, a life-saving treatment for severe and critically ill Covid-19 patients. Steroids reduce inflammation in the lungs for Covid-19 and appear to help stop some of the damage that can happen when the body's immune system goes into overdrive to fight off coronavirus. But they also reduce immunity and push up blood sugar levels in both diabetics and non-diabetic Covid-19 patients.

With the COVID-19 cases rising in India the rate of occurrence of mucormycosis in these patients is increasing

 QUESTION 9

http://medicinedepartment.blogspot.com/2021/05/covid-case-report-logs-from-may-2021.html?m=1

 1) Sort out these detailed patient case report logs into a single web page as a master chart 


2) In the master chart classify the patient case report logs into mild, moderate severe and 

3) indicate for each patient, the day of covid when their severity changed from moderate to severe or vice versa recognized primarily through increasing or decreasing oxygen requirements 

4) Indicate the sequence of specific terminal events for those who died with severe covid (for example, altered sensorium, hypotension etc). 


QUESTION 10:
Learning through the blogs and finding answers to the various questions was a great learning experience. The seminars conducted by our teachers in the afternoon really helped in understanding the concept better.
Even though we couldn’t see the patient and took the history over the phone getting further information from the doctors helped me in understanding the case better.
