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].

Q: A young patient presented in the emergency with haematemesis and was found to have massive splenomegaly. The following conditions are associated with the above clinical presentation except

Idiopathic thrombocytopenic purpura. ***Idiopathic thrombocytopenic purpura*** - While ITP can cause **bleeding** (including hematemesis) due to **thrombocytopenia**, it is generally **not associated with massive splenomegaly**. Splenomegaly, if present, is usually mild. - The primary defect in ITP is **immune-mediated platelet destruction**, not a cause of massive splenic enlargement, which typically results from conditions involving portal congestion, infiltrative diseases, or hemolytic processes. *Kala-azar* - **Kala-azar (visceral leishmaniasis)** is notoriously associated with **massive splenomegaly** and can cause **hematemesis** due to complications like **esophageal varices** or coagulopathy. - The parasite (Leishmania donovani) infiltrates the reticuloendothelial system, leading to profound splenomegaly. *Portal hypertension* - **Portal hypertension** is a direct cause of **massive splenomegaly** due to congestion and can lead to **hematemesis** from **ruptured esophageal varices**. - The increased pressure in the portal venous system causes blood to back up into the splenic vein, enlarging the spleen. *Malaria* - **Chronic malaria**, particularly from *Plasmodium falciparum* or *Plasmodium vivax*, can lead to significant, often **massive splenomegaly** (hyperreactive malarial splenomegaly). - While hematemesis is not a primary symptom, severe malaria can cause **coagulopathy** or contribute to **gastrointestinal bleeding** in complicated cases, though massive splenomegaly itself is a prominent feature.
