Q: Which of the following are risk factors for wound infection? 1. Malnutrition 2. Poor perfusion 3. Antibodies 4. Foreign body material Select the correct answer using the code given below.

1, 2 and 4. ***Correct: 1, 2 and 4*** The risk factors for wound infection include: - **Malnutrition** impairs the immune system and wound healing processes, making the patient more susceptible to infection - **Poor perfusion** (reduced blood supply) leads to decreased oxygen and nutrient delivery to the wound, hindering healing and immune cell function - **Foreign body material** within the wound creates a nidus for bacterial colonization and protects bacteria from immune defenses and antibiotics Antibodies are part of the body's immune defense system and **protect against infection** rather than being a risk factor for it. *Incorrect: 1, 3 and 4* While malnutrition (1) and foreign bodies (4) are risk factors, antibodies (3) are part of the immune defense and protect against infection, not increase its risk. *Incorrect: 2, 3 and 4* Poor perfusion (2) and foreign bodies (4) are risk factors, but antibodies (3) are protective components of the immune system. *Incorrect: 1, 2 and 3* Malnutrition (1) and poor perfusion (2) are significant risk factors, but antibodies (3) are a component of the host's defense mechanism against infection, not a risk factor.

Q: A midline neck swelling just below the hyoid bone and managed by Sistrunk's operation leads to postoperative need for thyroxine replacement. The most likely diagnosis is

thyroglossal cyst with only functioning thyroid tissue. ***thyroglossal cyst with only functioning thyroid tissue*** - A midline neck swelling below the hyoid bone is characteristic of a **thyroglossal cyst**. The need for **thyroxine replacement** post-Sistrunk's operation indicates that this cyst contained the patient's **only functioning thyroid tissue**. - In such rare cases, the body's entire thyroid gland develops abnormally within the thyroglossal duct, explaining the subsequent **hypothyroidism** after its removal. *solitary thyroid nodule* - A **solitary thyroid nodule** is typically located within the thyroid gland itself, which is lower in the neck than "just below the hyoid bone." - Simple removal of a solitary benign thyroid nodule would not, on its own, necessitate **thyroxine replacement** unless a total thyroidectomy was performed for other reasons, or the patient had underlying thyroid dysfunction. *thyroglossal cyst* - While a **thyroglossal cyst** fits the description of a midline neck swelling below the hyoid, simply diagnosing it as a cyst doesn't explain the need for **thyroxine replacement**. - Most thyroglossal cysts are benign and contain no functional thyroid tissue, so their removal via a Sistrunk's operation does not typically lead to **hypothyroidism**. *lateral aberrant thyroid* - **Lateral aberrant thyroid tissue** is typically found in the lateral neck, often associated with a branchial cleft anomaly, not in the midline below the hyoid bone. - While it can contain functional thyroid tissue, its location and the specific context of a Sistrunk's operation pointing to a midline anomaly make this diagnosis less likely.

Q: A 40-year-old smoker presents with soreness of tongue since last 2 months. On examination, it is found that the oral hygiene is poor and there is a white plaque over the lateral border of the tongue. What is the next step in the management of this patient?

Edge biopsy of the lesion. ***Edge biopsy of the lesion*** - The patient's presentation with a **white plaque** on the lateral border of the tongue, coupled with **poor oral hygiene** and a history of **smoking**, raises high suspicion for **oral potentially malignant disorders**, including **leukoplakia** or early **squamous cell carcinoma**. - An **edge biopsy** is the most appropriate next step to obtain a definitive histological diagnosis, which is crucial for determining the correct management strategy and ruling out malignancy. - The lateral border of the tongue is a **high-risk site** for oral cancer, and any persistent lesion in a smoker warrants tissue diagnosis. *Oral antifungal treatment* - This would be indicated if the white plaque were consistent with **oral candidiasis (thrush)**, which typically presents as **scrapable** white patches with a cottage cheese-like appearance. - Given the patient's significant risk factors (smoking, 2-month duration) and the location (lateral tongue border), empirical antifungal treatment without a definitive diagnosis would inappropriately delay management if the lesion is precancerous or cancerous. *Local topical cauterization* - **Cauterization** is contraindicated for undiagnosed oral lesions, especially those suspected of having malignant potential, as it could obscure the true histology and destroy tissue needed for diagnosis. - This method is only suitable for small, confirmed benign lesions or for hemostasis, never as a diagnostic or first-line approach. *Oral vitamin C supplementation* - While **vitamin C** supports overall health and tissue repair, there is no evidence it would resolve a suspicious white plaque on the tongue, especially one with potential malignant transformation. - Delaying proper diagnostic evaluation with supplementation alone could lead to progression of a serious underlying condition such as oral cancer.

Q: A 60-year-old lady presents with a recent onset increase in a long standing swelling on the front of the neck. The swelling, which was small, had been present since last 30 years, but has now increased to more than twice the size in the last 2 months. On examination, the swelling is firm to hard in consistency and moves with deglutition. What is the most likely cause of this clinical presentation?

Malignant transformation. ***Malignant transformation*** - A long-standing **benign thyroid swelling** (like a nodular goiter or adenoma) in an older patient that suddenly and rapidly increases in size, becomes firm/hard, and is associated with new symptoms suggests **malignant transformation**. - Additionally, factors like age over 60, female sex and change in consistency are concerning for **thyroid carcinoma**. *Myxomatous transformation* - This typically refers to the accumulation of **mucinous material** and is not a common or principal cause of rapid, significant enlargement and hardening in a long-standing thyroid swelling. - It does not explain the **rapid increase in size** and **firm consistency** described. *Haemorrhage* - While hemorrhage into a thyroid nodule can cause a **sudden increase in size** and pain, it usually presents as an acutely painful, tender swelling, and the consistency might be tense but not typically described as "firm to hard." - The rapid change in size over **two months** is more suggestive of cellular proliferation rather than a resolving bleed. *Cystic degeneration* - Cystic degeneration can explain some fluctuation in size over time, but a **rapid increase to more than twice the size** within two months, especially accompanied by a **firm to hard consistency**, is not characteristic of simple cystic change. - Cysts are typically softer or fluctuant on palpation, not firm and hard.

Q: Which among the following are complications of liver trauma? 1. Liver abscess 2. Biliary fistula 3. Portal thrombosis 4. Liver failure Select the correct answer using the code given below.

1, 2 and 4. ***1, 2 and 4*** - **Liver abscess** is a well-recognized complication resulting from infected devitalized tissue, hematoma, or bile contamination following liver trauma. - **Biliary fistula** is a common complication occurring when bile leaks from damaged intrahepatic or extrahepatic bile ducts, potentially forming external fistulas or bilomas. - **Liver failure** may result from extensive parenchymal damage, massive blood loss causing hepatic ischemia, coagulopathy, and metabolic derangements. - These three represent the **most common and clinically significant** complications of liver trauma encountered in clinical practice. *1, 2 and 3* - While **portal thrombosis** can theoretically occur after portal vein injury in liver trauma, it is a **rare complication** compared to liver abscess, biliary fistula, and liver failure. - This option incorrectly prioritizes portal thrombosis over the more common and clinically significant complication of liver failure. *2, 3 and 4* - This option incorrectly omits **liver abscess**, which is one of the most important delayed complications of liver trauma. - Abscess formation from infected hematomas or devitalized tissue is far more commonly encountered than portal thrombosis. *1, 3 and 4* - This option incorrectly omits **biliary fistula**, which is one of the most frequent complications of liver trauma. - Bile duct injury with subsequent bile leakage occurs in a significant proportion of liver trauma cases, making biliary fistula more clinically relevant than portal thrombosis.
