3)There was seizure free period in between but again sudden episode of GTCS why?resolved spontaneously why?
■ Seizures are resolved and seizure free period got achieved after medical intervention but sudden episode of seizure was may be due to any persistence of excitable foci by abnormal firing of neurons.
4) What drug was used in suspicion of cortical venous sinus thrombosis?
■ Anticoagulants are used for the prevention of harmful blood clots.
Clexane ( enoxaparin) low molecular weight heparin binds and potentiates antithrombin three a serine protease Inhibitor to form complex and irreversibly inactivates factor xa.

1.What is the difference btw heart failure with preserved ejection fraction and with reduced ejection fraction?
■ Preserved ejection fraction (HFpEF) – also referred to as diastolic heart failure. The heart muscle contracts normally but the ventricles do not relax as they should during ventricular filling (or when the ventricles relax).
■ Reduced ejection fraction (HFrEF) – also referred to as systolic heart failure
■ HFpEF is preceded by chronic comorbidities, such as hypertension, type 2 diabetes mellitus (T2DM), obesity, and renal insufficiency, whereas HFrEF is often preceded by the acute or chronic loss of cardiomyocytes due to ischemia, a genetic mutation, myocarditis, or valvular disease
2.Why haven't we done pericardiocenetis in this pateint?
■ Pericardiocentesis is not done here Because the effusion was self healing ,It reduced from 2.4cm to 1.9 cm.
3. What are the risk factors for development of heart failure in the patient?
■ risk factors for development of heart faliure in this patent
■ Alcohol abuse increases the risk of atrial fibrillation, heart attack and congestive heart failure
■ high blood pressure
■ Smoking
■ Diabetes
■ AV block can be associated with severe bradycardia and hemodynamic instability. It has a greater risk of progressing to third-degree (complete) heart block or asystole, wosening of pericardial effusion leaing to cardiac tamponade.
4.What could be the cause for hypotension in this
(May be secondary to TB)
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?
■ *the anatomical site is BLOOD VESSELS;
* ETIOLOGY:
The physical stress of hypertension 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.
The most likely cause of arterial thrombosis is artery damage due to atherosclerosis. Atherosclerosis occurs when a person has a buildup of plaque on the walls of their arteries. The arteries then begin to narrow and harden, which increases a person's risk of developing arterial thrombosis.
2) 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. Dytor
mechanism: Through its action in antagonizing the effect of aldosterone, spironolactone inhibits the exchange of sodium for potassium in the distal renal tubule and helps to prevent potassium loss.
2. TAB. Acitrom
mechanism: Acenocoumarol inhibits the action of an enzyme Vitamin K-epoxide reductase which is required for regeneration and maintaining levels of vitamin K required for blood clotting
3. TAB. Cardivas
mechanism:Carvedilol works by blocking the action of certain natural substances in your body, such as epinephrine, on the heart and blood vessels. This effect lowers your heart rate, blood pressure, and strain on your heart. Carvedilol belongs to a class of drugs known as alpha and beta-blockers.
4. INJ. HAI S/C
MECHANISM:Regulates glucose metabolism
Insulin and its analogues lower blood glucose by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production; insulin inhibits lipolysis and proteolysis and enhances protein synthesis; targets include skeletal muscle, liver, and adipose tissue
5.TAB. Digoxin
mechanism:
Digoxin has two principal mechanisms of action which are selectively employed depending on the indication:
Positive Ionotropic: It increases the force of contraction of the heart by reversibly inhibiting the activity of the myocardial Na-K ATPase pump,
an enzyme that controls the movement of ions into the heart.
6. Hypoglycemia symptoms explained
7. Watch for any bleeding manifestations like Petechiae, Bleeding gums.
8. APTT and INR are ordered on a regular basis when a person is taking the anticoagulant drug warfarin to make sure that the drug is producing the desired effect.
3) What is the pathogenesis of renal involvement due to heart failure (cardio renal syndrome)? Which type of cardio renal syndrome is this patient?
■ *cardiorenal syndrome type 4 is seen in this patient.
4) What are the risk factors for atherosclerosis in this patient?
■ effect of hypertention
They can also impair blood vessels' ability to relax and may stimulate the growth of smooth muscle cells inside arteries. All these changes can contribute to the artery-clogging process known as atherosclerosis.
5) Why was the patient asked to get those APTT, INR tests for review?
■ APTT and INR are ordered on a regular basis when a person is taking the anticoagulant drug warfarin to make sure that the drug is producing the desired effect.
■ Here, an INR of 3-4.5 is recommended. Warfarin should be started in conjunction with heparin or low molecular weight heparin when the diagnosis of venous thromboembolism is confirmed, although local protocols may vary in their starting doses and titration schedule.
1. How did the patient get relieved from his shortness of breath after i.v fluids administration by rural medical practitioner?
Because of the fluid loss occurred to the patient
there is decreased preload- so, SOB occurred due to decreased CO
IV fluids administered- there is increased preload- SOB decreased due to better of cardiac output.
2. What is the rationale of using torsemide in this patient?
Torsemide used to relieve abdominal distension.
3. Was the rationale for administration of ceftriaxone? Was it prophylactic or for the treatment of UTI?
IT IS THE TREATMENT FOR UTI
Rationale- Used for any bacterial infection.

Questions
1.Why is the child excessively hyperactive without much of social etiquettes ?
▪︎ Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inattention, or excessive activity and impulsivity, which are otherwise not appropriate for a person's age
▪︎For a diagnosis, the symptoms have to be present for more than six months, and cause problems in at least two settings (such as school, home, work, or recreational activities).
2. Why doesn't the child have the excessive urge of urination at night time ?
1. Psychosomatic disorder
3. How would you want to manage the patient to relieve him of his symptoms?
▪︎ If the cause is an overactive bladder, a medication known as an anticholinergic may be used. These prevent abnormal involuntary detrusor muscle contractions from occurring in the wall of the bladder
▪︎ To treat attention deficit hyperactivity disorder:
▪︎For children 6 years of age and older, the recommendations include medication and behavior therapy together — parent training in behavior management for children up to age 12 and other types of behavior therapy and training for adolescents. Schools can be part of the treatment as well.
▪︎Methylphenidate A stimulant and a medication used to treat Attention Deficit Hyperactivity Disorder. It can make you feel very ‘up’, awake, excited, alert and energised, but they can also make you feel agitated and aggressive. They may also stop you from feeling hungry.
▪︎ Amphetamine belongs to a class of drugs known as stimulants. It can help increase your ability to pay attention, stay focused on an activity, and control behavior problems. It may also help you to organize your tasks and improve listening skills.
● Question no. 6 : Infectious diseases
▪︎Cough since 2 months on taking food and liquids and regurgitation of food seen.
▪︎Difficulty in swallowing since 2 month . It was initially difficult only with solids but then followed by liquids also.
▪︎H/O weight loss of 10 Kgs since 2 months, hoarseness of voice, inadequate sleep since 2 months
▪︎Laryngeal crepitus positive
All the above findings are very much indicative of tracheo esophageal fistula
There is a very high chance of development of immune reconstitution inflammatory syndrome in this patient
■Immune reconstitution inflammatory syndrome (IRIS) :
This is the condition mostly seen in AIDS after initiating antiretroviral therapy (ART) therapy in HIV-infected / immuno compromised patients resulting from restored immunity to specific infectious or non-infectious antigens
Risk factors:
● Question no.7 : Infectious disease and Hepatology
▪︎ Proximity to gall bladder is another risk factor for the liver.
▪︎ The usual pathophysiology for pyogenic liver abscesses is bowel content leakage and peritonitis. Bacteria travel to the liver via the portal vein and resides there. Infection can also originate in the biliary system. Hematogenous spread is also a potential etiology.
▪︎ Septic emboli cause several microabscesses which combine to form one large abscess.
■ Single abcess,
■ Right lobe involvement,
■ Route of ingestion is orofecal route
▪︎ INJECTION. ZOSTUM 1.5 gm IV BD (twice daily)
Zostum is a combination of drugs - SULBACTUM (pencillin) & CEFOPERAZONE(cephalosporin) [Antibiotic]: It is used here to treat if any bacterial cause
▪︎ INJECTION. METROGYL 500mg IV TID ( thrice daily )
Metrogyl has the drug called METRONIDAZOLE [Antibiotic]: For amoebic cause
▪︎ INJECTION. OPTINEURIN 1amp in 100 ml NS( Nor
mal Saline) IV OD ( once daily)
Optineurin is a multivitamin drug { A combination of B1,B2, B3, B5,B6, B12 } given here as a supplement
▪︎ TAB. ULTRACET 1/2 QID( four times a day)
Ultracet is a combination of drugs - TRAMADOL(opiod analgesic) and ACETAMINOPHEN (analgesic and antipyretic) : Given for pain and fever
▪︎ TAB. DOLO 650 mg SOS (if needed) given for fever and pain
▪︎ We donot aspirate the pus since it is self resolving and aspiration is associated with several other complications.
▪︎ we administer patient with analgesic and antipyretic such as tab.dolo &tab.Ultracet.
■ (Anti amoebic antibodies )ELISA is the confirmatory investigation
● Question no.8 : Infectious diseases
