Q: Which test is being performed in the image shown below? (Recent NEET Pattern 2016-17)

Perthes test. ***Perthes test*** - The image shows a **tourniquet placed high on the thigh** to occlude the great saphenous vein at the saphenofemoral junction, with the patient then asked to **ambulate**. This maneuver is characteristic of the Perthes test. - This test is used to assess the **patency of deep veins** and the competence of perforator veins in the presence of varicose veins by observing the collapse or distention of the superficial varicosities upon exercise. *Three Tourniquet test* - The Three Tourniquet test, also known as the **multiple tourniquet test**, involves applying tourniquets at different levels (groin, knee, ankle) to localize the site of incompetent perforator veins. - The image distinctly shows only a **single tourniquet** placed near the groin, not multiple as implied by 'Three Tourniquet test'. *Brodie Trendelenburg test* - The Brodie Trendelenburg test involves **elevating the leg** to empty varicosities before applying a tourniquet and observing refilling upon standing. - The image shows the limb in a dependent position with a tourniquet applied, which is not the procedure for the Brodie Trendelenburg test. *Schwartz test* - The Schwartz test involves **percussing a varicose vein** distally and palpating proximally to detect a **fluid thrill**, indicating valvular incompetence. - The image does not depict percussion or palpation of the vein; instead, it shows a tourniquet in place and the superficial varicosities. *Pratt's test* - Pratt's test involves applying **multiple tourniquets** along the leg after elevation and bandaging from below upward, then removing bandages to map incompetent perforators. - The image shows a **single tourniquet** with the patient ambulatory, not the systematic mapping procedure characteristic of Pratt's test.

Q: Which of the following is true regarding this condition?

Needle aspiration yields fluid that does not coagulate. ***Needle aspiration yields fluid that does not coagulate*** - The image depicts a large, translucent, fluid-filled cystic mass, characteristic of a **cystic hygroma** (lymphatic malformation). - Aspiration of a cystic hygroma typically yields **clear to straw-colored fluid** that is rich in protein but **does not coagulate** because it is lymphatic fluid, not blood. *Most common site is anterior triangle neck* - While cystic hygromas most commonly occur in the **neck**, they are typically found in the **posterior triangle**, not the anterior triangle. - The lesion in the image appears to be a large, diffuse cystic mass extending from the neck into the mediastinum or axilla. *It is due to vascular malformation* - This condition is a **lymphatic malformation**, specifically a cystic hygroma, not a vascular malformation. - **Vascular malformations** involve blood vessels and would typically present with different characteristics, such as being compressible and potentially blanching. *Usually decreases on crying* - Crying or straining typically **increases the size** of a cystic hygroma due to increased intrathoracic pressure, which impedes lymphatic flow and causes distention of the lymphatic sacs. - This characteristic helps differentiate it from conditions that might decrease in size with pressure. *Typically appears after 5 years of age* - Cystic hygromas are **congenital malformations** that are usually present at birth or become apparent within the **first 2 years of life** (approximately 90% by age 2). - Late presentation after 5 years of age is uncommon and would be unusual for this condition.

Q: A 12-year-old patient with esophageal varices is managed by the procedure shown in the image. All of the following statements regarding this condition are true except:

This is the definitive treatment. ***This is the definitive treatment*** - The image shows a **Sengstaken-Blakemore tube** being used, which is a temporary measure for controlling **bleeding esophageal varices**. - It is an emergency treatment used for stabilization and does not address the underlying cause of varices or prevent future bleeding. - **Definitive treatments** include endoscopic variceal ligation (EVL), sclerotherapy, or TIPS procedure. *Sengstaken-Blakemore tube* - The device shown in the image, with balloons and multiple lumens, is indeed a **Sengstaken-Blakemore tube**, used for **tamponade of actively bleeding esophageal varices**. - This tube features a gastric balloon and an esophageal balloon, along with lumens for suction, designed to exert pressure on the bleeding varices. *Gastric balloon is inflated with 400 mL of air* - The **gastric balloon** of a Sengstaken-Blakemore tube is typically inflated with **200-500 mL of air** (often around 250-300 ml in adults, 150 ml in children) to anchor the tube and compress gastric varices. - While 400 mL is within the general range, the exact volume can vary based on patient size and clinical protocol. *Esophageal balloon is inflated with 40 mm Hg pressure of air* - The **esophageal balloon** is indeed inflated to a pressure of **20-45 mmHg (typically 30-45 mmHg)** to compress esophageal varices. - This pressure application is critical for achieving local hemostasis in acute bleeding episodes. *Should be kept inflated for a maximum of 24-48 hours* - The balloons should be deflated after **24-48 hours maximum** to prevent complications such as **esophageal necrosis, ulceration, or perforation**. - Prolonged inflation can cause pressure necrosis of the esophageal or gastric mucosa.

Q: A 34-year-old male patient complains of sudden severe epigastric pain along with vomiting, tenderness, guarding. On examination there is abdominal rigidity and tachycardia. He admits to taking NSAIDs for pain. The radiological examination of the patient is given below. All statements given below are true except?

Pain often radiates to groin. ***Pain often radiates to groin*** - The clinical presentation (sudden severe epigastric pain, vomiting, tenderness, guarding, rigidity, tachycardia, NSAID use) and the radiological imaging showing **free air under the diaphragm** are highly suggestive of **perforated viscus**, likely a perforated peptic ulcer. - Pain from a perforated ulcer typically **radiates to the shoulder** (due to diaphragmatic irritation) or generalizes throughout the abdomen, but **not typically to the groin**. *Tenderness on per-rectal examination* - **Tenderness on per-rectal examination** can be present in cases of generalized peritonitis, as the inflammation can extend to the pelvic peritoneum. - This finding is consistent with the diffuse inflammation caused by a perforated viscus. *Blumberg sign is positive* - **Blumberg sign**, also known as **rebound tenderness**, is a classic sign of **peritoneal irritation** or peritonitis. - Given the severe abdominal pain, guarding, and rigidity, peritonitis is highly likely in this patient, making a positive Blumberg sign expected. *Dullness over flanks is observed* - **Dullness on percussion over the flanks** indicates the presence of **fluid** in the peritoneal cavity (ascites). - In a perforated viscus, gastric or intestinal contents, along with inflammatory exudates, can accumulate in the dependent areas of the abdomen, leading to dullness in the flanks.
