| 2 | ✅ Correct Answer: B) Down Syndrome
A single transverse palmar crease (sometimes called a "simian crease") is seen in about 45–60% of infants with Down Syndrome.
It results from abnormal development of palmar flexion creases during fetal growth.
While it can occasionally be found in healthy individuals, its presence alongside other features (hypotonia, epicanthic folds, flat facial profile) strongly suggests Trisomy 21.
Other syndromes listed (Turner, Marfan, Edwards) have distinct hallmark features but do not typically present with this crease.

| 16 |  Epiglottis in a 5-year-old boy with respiratory distress and drooling. A lateral soft tissue neck radiograph shows a markedly thickened epiglottis (white arrow), which is referred to as the “thumb” sign. The aryepiglottic folds (black arrow) also are thickened.
💎 @profmedken | @MedkenHub | 256 |
| 17 |  A 73-year-old patient with active colon cancer and massive pulmonary embolism.
There was a worm-shaped large mobile risky clot in the right atrium (RA), which was very dangerous, especially with right ventricular (RV) dysfunction.
The patient received a half-dose (50 mg) of alteplase.
Follow-up echocardiography showed complete resolution of the RA clot.
The patient was later discharged with alleviated symptoms and some improvement in RV function.

| 18 | The correct answer is Kussmaul sign.
🩺 Explanation
▶️ Kussmaul sign:
- Defined as a paradoxical rise in jugular venous pressure (JVP) during inspiration.
- Normally, inspiration decreases intrathoracic pressure ➔ increases venous return ➔ lowers JVP.
- In conditions like constrictive pericarditis, restrictive cardiomyopathy, or right-sided heart failure, the right ventricle cannot accommodate the increased venous return. This leads to a rise in JVP instead.
➲ Homan sign ➔ calf pain on dorsiflexion of the foot, associated with deep vein thrombosis.
➲ Murphy sign ➔ inspiratory arrest due to pain on palpation of the right upper quadrant, seen in acute cholecystitis.
➲ Trousseau sign ➔ carpopedal spasm induced by inflating a blood pressure cuff, seen in hypocalcemia.
🔑 Clinical Pearl
Kussmaul sign is a bedside clue to impaired right ventricular filling. It helps differentiate constrictive pericarditis (positive Kussmaul sign) from cardiac tamponade (usually absent Kussmaul sign).
