2024-03-22 22:06:01 Answer is D (Polyarteritis nodosa)

Amongst the options provided renal artery stenosis is least likely to
be seen in association with Polyarteritis nodosa.
Atherosclerosis and Fibromuscular disease

- Renal artery stenosis is produced predominantly by
atherosclerotic occlusive disease (80% to 90% of patients) or
tibromuscular dysplasia (10-15% of patients).- CMDT'06 p 460

- he common cause of renal artery stenosis in the middle aged and
elderly is an atheromatous plaque at origin of renal artery. Harrison

- In younger women stenosis is due to intrinsic structural
abnormalities of the arterial wall caused by a heterogenous group of lesions called 'fibromuscular dysplasia'.
PAN or Takayasu arteritis ?
CMDT do not mention PAN or Takayasu arteritis as a cause for
renal artery stenosis.
However, Takayasu arteritis is certainly a more common cause of
renal artery stenosis than PAN


Causes of Renal artery stenosis :
1. Atherosclerosis
2. Fibromuscular dysplasia
3. Non specific Aorto arteritis
4. Takayasu arteritis and giant cell arteritis (Takayasu > Giant cell)
5. Antiphospholipid syndrome
6. Transplant renal artery stenosis
7. Renal artery embolism
8. Dissecting aneurysm of aorta
9. Radiation arteritis

2024-03-13 15:42:01 Correct Answer - D
Ans. is 'd' i.e., neuropsychiatric manifestations

Hyperkalemia is seen in hemolytic urenic syndrome as a result of
renal failure.

ABOUT NEUROPSYCHIATRIC MANIFESTATIONS
* Neurological manifestations are used to distinguish between
Hemolytic uremic syndrome and Thrombotic Throm bocytopenic
Purpura.

* H.U.S. is distinguished from T.T.P by the absence of neurological
symptoms and the prominence of acute renal failure.

* Recent studies, however have tended to blurr these clinical
distinctions. Many adult patients with "T. T.P. lack one or more of the five criteria and patients with "HUS" have fever and neurological
dysfunction.

2024-03-04 14:29:01 Correct Answer - C
Ans. is 'c' i.e., Acute viral hepatitis
Pathological features of acute viral hepatitis

1) Panlobular infiltration of mononuclear cells
This mononuclear infiltration primarily consists of —> Lymphocytes, Plasma cells, Eosinophils Inflammatory infiltrate may spill over into the adjacent parenchyma to cause necrosis of periportal hepatocytes 4 interface hepatitis, can occur in both acute and chronic hepatitis.

2) Hepatic cell damage - It consits of
a) Hepatic cell necrosis - The necrosis is usually focal or
centirzonal.
Sometimes severe necrosis such as bridging or subacute hepatic
necorsis occurs.

b) Ballooning of cells - Damaged cells show diffuse swelling
known as ballooning degeneration.

c) Acidophilic degeneration of hepatocytes - In this single necrotic liver cell has coagulated pink cytoplasm and it shows pyknosis or karyolysis. These are called councilman bodies.

2024-02-22 09:56:01 Correct Answer - A
Answer- A. Sepsis

Thrombocytopenia is a common laboratory abnormality that has
been associated with adverse outcomes in ICU patients.

Thrombocytopenia is defined as platelet count < 150 X 103 cells /
mcL.

Common causes of thrombocytopenia in ICU patients:

Sepsis
Disseminated intravascular coagulation Consumption (eg, major trauma, cardiopulmonary bypass) Dilution (with massive transfusion)
Myelosuppressive chemotherapy
Mechanical circulatory support devices (eg, intra-aortic balloon
pump)
Less common but important causes of thrombocytopenia that should not be missed:

Heparin-induced thrombocytopenia
Hemophagocytic syndrome
Uncommon causes of thrombocytopenia that develop during ICU admission
Drug-induced thrombocytopenia (other than heparin or cytotoxic
chemotherapy)

2024-02-01 10:41:01 Correct Answer - D
Answer- D. M component is IgA in 25% of the patients The immunoglobulins move heterogeneously in an electric field and form a broad peak in the gamma region.

The y globulin region of the electrophoretic pattern is usually increased in the sera of patients with plasma cell tumors.

There is a sharp spike in this region called M component (M for monoclonal).

The serum M component in multiple myeloma will be IgG in 53% of patients, IgA in 25%, and IgD in 1%; 20% ofMietits will have only
light chains in serum and urine.

2023-12-31 18:01:01 Correct Answer - C
Answer is C (Propranolol)
The symptoms of the patient and echocardiographic finding of
asymmetrical septal hypertrophy almost confirms the diagnosis of
Hypertrophic cardiomyopathy. Beta Blockers should be the initial
drug Q in symptomatic individuals
Management of HOCM
Avoidance of strenuous physical activity

Beta Blockers should be the initial drug Q in symptomatic individuals.
They reduce:
- Heart rate
- Blood pressureStiffness of left ventricle
- Fatal arrythmias

Calcium channel BlockersQ (verapamil and diltiazem) are alternative
drugs.
- They reduce-stiffness of ventricle
- Elevated diastolic pressures

Amiadarone may be used to reduce arrythmias.
Surgical myomectomy
