Q: The following statements regarding small bowel tuberculosis are correct except

The strictures are common in the ulcerative type. ***The strictures are common in the ulcerative type*** - While both ulcerative and hyperplastic types of small bowel tuberculosis can lead to complications, **strictures are more characteristic of the hyperplastic type**. - In the **hyperplastic form**, chronic inflammation, fibrosis, and granuloma formation cause wall thickening and luminal narrowing, resulting in strictures. *There are two types : ulcerative and hyperplastic* - This statement is correct. Small bowel tuberculosis is broadly classified into **ulcerative** and **hyperplastic** forms, with mixed types also occurring. - The type is often determined by the interplay between the virulence of the organism and the host's immune response. *In the ulcerative type, the bowel serosa is studded with tubercles* - This statement is correct. The **ulcerative type** is often associated with the **spread of infection to the serosa**, leading to the formation of visible **tubercles**. - This indicates more extensive disease and possible peritoneal involvement. *The ulcerative type occurs when the virulence of the organism is greater than the host defence* - This statement is correct. The **ulcerative form** is often observed when the **organism's virulence is high** and/or the host's **immune response is weak**, leading to destructive lesions. - This imbalance results in caseating necrosis and ulceration of the bowel wall.

Q: Systemic Inflammatory Response Syndrome (SIRS) diagnostic criteria include the following except

White cell count 12,000/mm³ or 10% **immature (band) forms**. [2] - This option correctly states a **WBC count below 4000/mm³**, which is indeed a criterion for SIRS. *Temperature > 38°C or < 36°C* - This is a correct criterion for SIRS, indicating a significant deviation from normal body temperature. [1] - Both **fever (hyperthermia)** and **hypothermia** are signs of systemic inflammation. *Tachycardia with a heart rate of more than 90/min.* - This is a correct criterion for SIRS, reflecting the increased metabolic demand and sympathetic activation during systemic inflammation. [2] - A persistent **heart rate above 90 bpm** is considered indicative of such stress. *Tachypnoea with a respiratory rate of > 20/min.* - This is a correct criterion for SIRS, showing the body's attempt to compensate for metabolic disturbances or increased oxygen demand. [2] - A **respiratory rate greater than 20 breaths per minute** or a PaCO2 less than 32 mmHg are both SIRS criteria. [Practice more UPSC-CMS 2023 questions on OnCourse]

Q: When a patient suffers from critical limb ischemia, the ankle-brachial pressure index (ABPI) is less than ...

0.3. ***0.3*** - A value of **less than 0.3** indicates **severe blood flow impairment**, consistent with critical limb ischemia, necessitating urgent intervention [1]. - This extremely low ABPI reflects a profound decrease in perfusion to the lower extremity [1]. *0.7* - An ABPI of **less than 0.7** typically suggests **moderate peripheral artery disease (PAD)**, which could cause claudication but is not usually indicative of critical limb ischemia [1]. - While concerning, it does not represent the severe, limb-threatening ischemia implied by the term "critical." *1.0* - An ABPI of around **1.0 (0.9-1.3)** is considered **normal**, indicating healthy blood flow without significant arterial obstruction. - This value would rule out any significant peripheral artery disease, including critical limb ischemia. *0.9* - An ABPI of **less than 0.9** generally suggests **peripheral artery disease (PAD)**, which can cause symptoms like intermittent claudication [1]. - However, it is not low enough to diagnose critical limb ischemia, which represents a more severe state of arterial insufficiency [1].

Q: Which of the following most strongly suggests the diagnosis of primary hyper-parathyroidism ?

Serum calcium above 11 mg/dL. ***Serum calcium above 11 mg/dL*** - **Hypercalcemia** is the hallmark of primary hyperparathyroidism, as excessive parathyroid hormone (PTH) leads to increased calcium reabsorption from bones and kidneys [1, 3]. - A serum calcium level significantly above the normal range (typically 8.5-10.2 mg/dL) strongly suggests a parathyroid-related issue; specifically, levels exceeding 11.4 mg/dL (2.85 mmol/L) often warrant surgical consideration [1]. *Serum acid phosphatase above 120 IU/L* - **Elevated acid phosphatase** is more commonly associated with conditions like **prostatic carcinoma** with bone metastases or certain hematologic malignancies. - It is not a primary diagnostic marker for hyperparathyroidism. *Urinary calcium below 100 mg/day* - **Low urinary calcium** (hypocalciuria) is characteristic of **familial hypocalciuric hypercalcemia (FHH)**, a genetic condition that can mimic primary hyperparathyroidism [1]. - In primary hyperparathyroidism, **urinary calcium excretion is typically normal or high** due to the PTH-mediated increase in filtered calcium load. *Serum alkaline phosphatase above 120 IU/L* - **Elevated alkaline phosphatase** can indicate increased **bone turnover**, which can be seen in severe, prolonged primary hyperparathyroidism as an indicator of bone resorption [1, 2]. - However, it is a non-specific marker and can also be elevated in various liver diseases or other bone disorders; it is not as specific as hypercalcemia for diagnosing primary hyperparathyroidism [2].
