2) What are mechanism of action, indication and efficacy over placebo of each of the pharmacological and non pharmacological interventions used for this patient?
A. Pharmacological interventions used for the patient :
i) INJ.AUGMENTIN - amoxicillin + clavulanic acid
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.
Indication: To treat bacterial infections, shorten the course of the disease, prevent further deterioration of lung function, and prolong the period between exacerbations.
ii) TAB.AZITHROMYCIN
MOA: Azithromycin prevents bacteria from growing by interfering with their protein synthesis. It binds to the 50S subunit of the bacterial ribosome, thus inhibiting translation of mRNA.
Indication : To treat Acute exacerbations of COPD
iii) INJ.LASIX - Furosemide
MOA: Furosemide, like other loop diuretics, acts by inhibiting the luminal Na-K-Cl co-transporter in the thick ascending limb of the loop of Henle, by binding to the chloride transport channel, thus causing sodium, chloride, and potassium loss in urine.
Indication : To treat pedal edema
iv) TAB PANTOP
MOA : 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.
Indication : To treat the acidity caused by antibiotics
v) INJ.HYDROCORTISONE :
MOA : Hydrocortisone is as a Corticosteroid Hormone Receptor Agonist. It works by reducing inflammation (irritation and swelling) in the body.
vi) NEB. with IPRAVENT, BUDECORT
MOA :Ipratropium is an acetylcholine antagonist via blockade of muscarinic cholinergic receptors. Blocking cholinergic receptors decreases the production of cyclic guanosine monophosphate (cGMP). This decrease in the lung airways will lead to decreased contraction of the smooth muscles.
- Budesonide is a potent topical anti-inflammatory agent. [19] It binds and activates glucocorticoid receptors (GR) in the effector cell (e.g., bronchial) cytoplasm that allows the translocation of this budesonide-GR complex in the bronchi nucleus, which binds to both HDCA2 and CBP (HAT)
Indication : To treat shortness of breath
vii) TAB PULMOCLEAR
MOA : Acebrophylline is a compound which has been found to act both as a mucoregulating and a bronchodilating drug, works by relaxing the airways.
Indication :Treatment of COPD
Non-pharmacological interventions :
i) Head end elevation : The elevation of the head of bed (HOB) to a semi-recumbent position is associated with a decreased incidence of aspiration and ventilator-associated pneumonia (VAP). It also can increase the possibility of more homogeneous alveolar ventilation and possibly reduce the risk of lung injury caused by mechanical ventilation
ii) BiPAP: BiPAP therapy targets dysfunctional breathing patterns. By having a custom air pressure for when you inhale and a second custom air pressure when you exhale, the machine is able to provide relief to your overworked lungs and chest wall muscles.
Indication : To treat COPD
iii) Chest physiotherapy : Chest physiotherapy involves a number of physical techniques to help remove excess mucus from respiratory passages and improve breathing. The goal is to help patients breathe more freely and get more oxygen through the blood stream into all parts of the body.

- 2 years ago - Diagnosed with DM-2 and is using medication irregularly.
- 1 year ago - Seizure episode.
- 4 months ago - Seizure episode.
- 9 days ago - Irrelevant talking, laughing, short term memory loss and decreased appetite
Anatomical location of the problem: GABA receptors in the brain, lowers parts of brain mainly hypothalamus and thalamus
Primary etiology :Alcohol
2) What are mechanism of action, indication and efficacy over placebo of each of the pharmacological and non pharmacological interventions used for this patient?
A. Pharmacological interventions :
i) IVF NS and RL :
IV fluids help maintain a patient's hydration and electrolyte levels.
ii) INJ.THIAMINE :
Thiamine replacement is treatment for Wernicke's Encephalopathy ( occurs due to thiamine deficiency ) in order to reverse mental status changes and prevent further disease progression. Parenteral thiamine is used since intestinal absorption of thiamine is impaired in the case of alcoholics.
iii) INJ.LORAZEPAM:
MOA :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.Its inhibitory action in the amygdala helps with anxiety disorders
Indication : Alcohol withdrawal delirium , Wernicke's encephalopathy
iv) TAB.PREGABALIN
MOA: The site of action of both drugs is the alpha2-delta (alpha2-delta) protein, an auxiliary subunit of voltage-gated calcium channels. Pregabalin subtly reduces the synaptic release of several neurotransmitters, apparently by binding to alpha2-delta subunits, and possibly accounting for its actions in vivo to reduce neuronal excitability and seizures.
v) INJ.KCL IN NS : to treat the symptoms of Hypokalemia.
vi) SYP.POTKLOR : Potklor oral solution contains Potassium Chloride which is used to prevent and treat the low levels of potassium in the body.
3) Why have neurological symptoms appeared this time, that were absent during withdrawal earlier? What could be a possible cause for this?
4) What is the reason for giving thiamine in this patient?
A. Wernicke's encephalopathy is an acute neurological caused by thiamine deficiency , which primarily affects the peripheral and central nervous systems. Thiamine deficiency is characteristically associated with severe alcohol use disorder.
Thiamine, also known as Vitamin B1, is a coenzyme that is essential for intricate organic pathways and plays a central role in cerebral metabolism. 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.Neuronal death in the mammillary bodies and thalamus were implicated in multiple cases of Wernicke encephalopathy studied.
Thus thiamine is prescribed in this patient in order to reverse the mental status changes caused by Wernicke's Encephalopathy. Parenteral thiamine is used since intestinal absorption of thiamine is impaired due to chronic addiction of alcoholic.
5) What is the probable reason for kidney injury in this patient?
A. Alcohol and diabetes could have resulted for kidney injury in the patient. Alcohol causes changes in the function of the kidneys and makes them less able to filter the blood. Alcohol also affects the ability to regulate fluid and electrolytes in the body. When alcohol dehydrates (dries out) the body, the drying effect can affect the normal function of cells and organs, including the kidneys.
6). What is the probable cause for the normocytic anemia?
A. Normocytic anemia could have occurred probably because of alcohol abuse which eventually causes iron deficiency by causing defect in cell production. Other causes could be decreased bone marrow production of RBCs, due to erythropoitin deficiency due to kidney failure. Foot ulcer resulted in blood loss which could have resulted in normocytic anemia.
7) Could chronic alcoholism have aggravated the foot ulcer formation? If yes, how and why?
A. Yes., chronic alcoholism could have aggravated foot ulcer formation in this patient. Alcoholism impairs wound healing process resulting in persistent foot ulcer.

Anatomical location of the problem : Cerebral blood vessels
Primary etiology : Denovo hypertension, alcohol consumption, smoking
2) What are mechanism of action, indication and efficacy over placebo of each of the pharmacological and non pharmacological interventions used for this patient?
A. Pharmacological intervations :
i) TAB.VERTIN : Betahistine
MOA: Betahistine acts as a histamine analogue through 2 modes of action(1) agonist of H1 receptors and (2) antagonist of H3 receptors.
It has a direct stimulating (agonistic) effect on H1 receptors located on blood vessels in the inner ear. It appears to act on the precapillary sphincter in the stria vascularis of the inner ear, thus reducing the pressure in the endolymphatic space.
Indications : To treat hearing loss, tinnitus .
ii) INJ.ZOFER : Ondansetron
MOA: Zofer Injection works by inhibiting the action of a chemical substance known as serotonin. Serotonin is responsible for inducing nausea and vomiting. Ondansetron binds to a receptor known as 5-HT₃, thus inhibits the binding of serotonin to it and prevents vomiting and nausea
Indication : To prevent nausea and vomiting
iii) TAB.ECOSPORIN:
MOA: The antithrombotic action of aspirin (acetylsalicylic acid) is due to inhibition of platelet function by acetylation of the platelet cyclooxygenase (COX) at the functionally important amino acid serine529.
Indication: Ischemic stroke
iv) TAB.ATORVASTATIN
MOA : Atorvastatin competitively inhibits HMG-CoA reductase. By preventing the conversion of HMG-CoA to mevalonate, statin medications decrease cholesterol production in the liver. Thus it prevents the accumulation of cholesterol in wall of the arteries and prevents blockage of blood flow to the brain.
Indication : Cerebrovascular accident
v)TAB.CLOPIDOGREL
MOA:The active metabolite of clopidogrel selectively inhibits the binding of adenosine diphosphate (ADP) to its platelet P2Y12 receptor and the subsequent ADP- mediated activation of the glycoprotein GPIIb/IIIa complex, thereby inhibiting platelet aggregation.
Indication: CVA
3) Did the patients history of de novo HTN contribute to his current condition?
A. Yes, hypertension did contribute to cerebro-vascular accident (stroke) in this patient. 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.
4) Does the patients history of alcoholism make him more susceptible to ischemic or hemorrhagic type of stroke?

Indication: Ischemic stroke
2) TAB.ATORVASTATIN
MOA : Atorvastatin competitively inhibits HMG-CoA reductase. By preventing the conversion of HMG-CoA to mevalonate, statin medications decrease cholesterol production in the liver. Thus it prevents the accumulation of cholesterol in wall of the arteries and prevents blockage of blood flow to the brain.
Indication : Cerebrovascular accident
3) TAB.CLOPIDOGREL
MOA:The active metabolite of clopidogrel selectively inhibits the binding of adenosine diphosphate (ADP) to its platelet P2Y12 receptor and the subsequent ADP- mediated activation of the glycoprotein GPIIb/IIIa complex, thereby inhibiting platelet aggregation.
Indication: CVA
4. Does alcohol has any role in his attack?
A. Yes, alcohol has a contribution in his attack. Liver damage due to too much alcohol
can stop the liver from making substances that help your blood to clot. This can
increase your risk of having a stroke caused by bleeding in your brain.
5.Does his lipid profile has any role for his attack??
A. Yes, the patient had lower HDL levels which contribute to higher risk of stroke . HDL has anti-atherosclerotic and anti-inflammatory properties and is an important component in atherosclerosis. Serum HDL-cholesterol levels are inversely related to stroke risk.
There are several mechanisms by which HDL protects against atherosclerosis, including reverse cholesterol transport, antioxidant effects, anti-inflammatory effects, antithrombotic effects, and modification of endothelial function. Thus, lower HDL levels contribute to atherosclerosis which in turn blocks the blood supply to the brain and ultimately results in stroke.

- Behavior therapy, including training for parents; and
- Medications.
Medications :
FDA has approved two types of medications—stimulants and non-stimulants—to help reduce the symptoms of ADHD. 1) Stimulants, which contain various forms of methylphenidate and amphetamine, actually have a calming effect on hyperactive children with ADHD. They are believed to increase brain levels of dopamine—a neurotransmitter associated with motivation, attention, and movement.
2) FDA has also approved three non-stimulants to treat the symptoms of ADHD: Strattera (atomoxetine), Intuniv (guanfacine), and Kapvay (clonidine). These provide a useful alternative for children who do not tolerate stimulants well.

Questions:
1.Which clinical history and physical findings are characteristic of tracheo-oesophageal fistula?
A. In this patient, the following features are suggestive of TOF:
i) Cough since 2 months on taking food and liquids
Other features which favor the diagnosis of TOF are:
i) Difficulty in swallowing both solids and liquids
ii) H/O weight loss of 10 Kg since 2 months
iii) Hoarseness of voice
iv) Patient being both RVD positive and TB positive
2) What are the chances of this patient developing immune reconstitution inflammatory syndrome? Can we prevent it?
A.
The most effective prevention of IRIS would involve initiation of ART before the development of advanced immunosuppression. 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.
7) Infectious disease and Hepatology:
Link to patient details:
1. 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 ?
A. “Alcohol can predispose to ALA through a multitude of mechanisms, including hepatic damage by alcohol, lowered body resistance and suppression of liver function due to poor nutritional status of habitual consumers of alcohol, increased presence of amoebae in the liquor prepared locally with poor regard to aseptic procedures, and depression of immune mechanisms in chronic alcoholics.”
In experimental studies, the presence of 'iron' potentiates the in-vitro growth of Entamoeba histolytica (E. histolytica), and is also known to increase its in-vivo invasiveness in animal infections. Chronic alcoholism increases the hepatic iron deposition. We hypothesized that ALA occurs more commonly in livers with a high iron load as in alcoholics.
2. What is the etiopathogenesis of liver abscess in a chronic alcoholic patient ? ( since 30 years - 1 bottle per day)
3. Is liver abscess more common in right lobe ?
A. Liver abscess in common in right lobe as it receives more blood supply than the left lobe. Since the liver receives its blood circulation from the systemic and portal circulations, it is more susceptible to getting infections and abscesses from the bloodstream
4.What are the indications for ultrasound guided aspiration of liver abscess ?
A. Indications for ultrasound guided aspiration of liver abscess:
1) Left lobe abscess not amenable to percutaneous damage.
2) Amoebic abscess eroding into surrounding structures.
3) Liife-threatening hemorrhage with or without intraperitoneal rupture of abscess.
4) Failure of response to conservative therapy.
5) Septicemia from secondary infection.
B) Link to patient details:
QUESTIONS:
1) Cause of liver abcess in this patient ?
A. Amebic liver abscesses are caused by Entamoeba histolytica, a protozoan parasite. Amoebiasis spreads from eating food or water that has been contaminated with feces. This is sometimes due to the use of human waste as fertilizer. Amoebiasis is also spread through person-to-person contact. more in males
2) How do you approach this patient ?
3) Why do we treat here ; both amoebic and pyogenic liver abcess?
A. We treat both amoebic and pyogenic liver abscess so as to ensure complete treatment of the patient.
4) Is there a way to confirm the definitive diagnosis in this patient?
A. The diagnosis of an amebic liver abscess is made through a combination of characteristic findings on imaging and serologic testing. On imaging, there is a cystic intrahepatic cavity that is usually indistinguishable from other causes of liver abscesses. The majority of amebic liver abscesses are solitary lesions, although there can occasionally be multiple lesions, and they are more often found in the right lobe than the left. On ultrasound, the lesion is a round, well-defined hypoechoic mass . After healing, the periphery of the abscess may calcify and form a round, thin rim.

A) Link to patient details:
Questions :
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 etiology of the patient's problem?
A. Evolution of symptomatology:
- 3 years ago- diagnosed with hypertension
- . 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
- . 18 days ago- complained of similar events and went to the the local hospital, it was not subsided upon taking medication(antipyretics)
- . 11 days ago - c/o Generalized weakness and facial puffiness and periorbital oedema. Patient was in a drowsy state
- . 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
- . patient died 2 days ago
Anatomical location of the problem : Eye, nasal cavity Etiology : Diabetes
2) 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?
A. Amphotericin B has proven efficacy in the treatment of mucormycosis. At the present time, the liposomal formulation (AmBisome) is the drug of choice based on efficacy and safety data.
Experiments were performed on mice to demonstate the efficacy of Liposomal Amphotericin B and posconazole.
3) What are the postulated reasons for a sudden apparent rise in the incidence of mucormycosis in India at this point of time?
