An elderly patient with type 2 diabetes presents with extreme hyperglycaemia, very high plasma osmolality, severe dehydration and minimal ketosis. The diagnosis is:
सही उत्तर: ख) Hyperosmolar hyperglycaemic state
HHS typically affects older people with type 2 diabetes; residual insulin prevents significant ketosis while marked glucose and osmolality rises cause dehydration and confusion.

Recurrent hypoglycaemia with high serum insulin but LOW C-peptide suggests:
सही उत्तर: घ) Surreptitious injection of exogenous insulin
Endogenous insulin is secreted with C-peptide; exogenous insulin suppresses beta cells, so C-peptide is low. Insulinoma and sulfonylureas raise both.

The most common cause of hypercalcaemia in an otherwise well outpatient is:

Euvolaemic hyponatraemia with inappropriately concentrated urine and high urinary sodium, with normal thyroid and adrenal function, suggests:
सही उत्तर: क) Syndrome of inappropriate ADH secretion (SIADH)
In SIADH, water retention dilutes plasma while urine osmolality stays inappropriately high and urine sodium is high; hypothyroidism and adrenal insufficiency must be excluded.

The immediate treatment of an acute adrenal (Addisonian) crisis is:
सही उत्तर: ग) Intravenous hydrocortisone with saline
Adrenal crisis is treated urgently with parenteral hydrocortisone and intravenous 0.9% saline (with dextrose if hypoglycaemic).

The single best initial screening test for primary thyroid dysfunction is:

-
Flushing, diarrhoea and wheeze in a patient with liver metastases from a small intestinal tumour are best confirmed by measuring urinary:
सही उत्तर: घ) 5-Hydroxyindoleacetic acid (5-HIAA)
Carcinoid syndrome results from serotonin secretion reaching the systemic circulation (usually with liver metastases); serotonin is excreted as 5-HIAA.

-
Diarrhoea, weight loss, arthralgia and PAS-positive foamy macrophages in the small intestinal lamina propria suggest:
सही उत्तर: ख) Whipple's disease
Whipple's disease is caused by Tropheryma whipplei; PAS-positive macrophages in the lamina propria are characteristic, and it can also affect joints, heart and brain.

Spider naevi are usually found in the distribution of the:
सही उत्तर: ख) Superior vena cava
Spider naevi appear on the face, neck, upper chest and arms (SVC territory); more than a few suggest chronic liver disease due to excess oestrogen.

-
A serum–ascites albumin gradient (SAAG) of 1.1 g/dL or more indicates that ascites is due to:
सही उत्तर: क) Portal hypertension
A high SAAG (1.1 g/dL or more) reflects portal hypertension, as in cirrhosis or cardiac ascites; a low SAAG suggests peritoneal disease or hypoalbuminaemia.
