Q: Match List-I with List-II and select the correct answer using the code given below the Lists:

A→3 B→2 C→4 D→1. ***A→1 B→2 C→3 D→4*** - This represents the **best available matching** among the given options, where each category is paired with the most appropriate example from the choices provided. - While not the ideal pharmacological classification, this option provides the most logical **wound care agent pairing** within the constraints of the available answers. *A→3 B→1 C→4 D→2* - Incorrectly matches **debriding agent (B)** with **benzoyl benzoic acid (1)**, which is primarily a **keratolytic agent** rather than a debriding agent. - Misplaces **enzymatic agent (D)** with **Vandase (2)**, when Vandase is better classified as a **debriding enzyme**. *A→3 B→1 C→2 D→4* - Incorrectly pairs **biological membrane (C)** with **Vandase (2)**, which is an **enzymatic preparation** not a biological membrane. - Creates multiple **mismatched classifications** that don't align with standard wound care categories. *A→1 B→2 C→4 D→3* - Incorrectly matches **polymeric film (A)** with **benzoyl benzoic acid (1)**, which is not a **film dressing** but a topical agent. - Misplaces **enzymatic agent (D)** with **Opsite/Tegaderm (3)**, which are **synthetic polymeric films** not enzymatic preparations.

Q: The percutaneous PAIR therapy used in the treatment of uncomplicated hepatic hydatid cyst can be associated with the following complications, except

bradycardia. ***bradycardia*** - **Bradycardia is not a recognized primary complication** of percutaneous aspiration, injection, and re-aspiration (PAIR) therapy for hydatid cysts. - While bradycardia can occur as a **vasovagal response during any invasive procedure**, it is not specifically listed among the complications of PAIR therapy in standard medical literature. - The typical cardiovascular manifestation of anaphylaxis (a known PAIR complication) is **tachycardia**, not bradycardia. *hypotension* - **Hypotension** is a well-documented complication of PAIR therapy, occurring due to **anaphylactic reaction** from leakage of antigenic hydatid fluid into the circulation. - It can also result from **intra-abdominal hemorrhage** if a major vessel is inadvertently punctured during the procedure. *vomiting* - **Vomiting** can occur as part of a **systemic allergic reaction or anaphylaxis** triggered by the release of hydatid cyst contents. - It may also be a manifestation of peritoneal irritation if cyst contents leak into the peritoneal cavity. *anaphylaxis* - **Anaphylaxis** is the most feared and well-documented complication of PAIR therapy, caused by the release of **highly antigenic hydatid cyst fluid** (containing protoscolices and hydatid antigens) into the host's system. - This severe Type I hypersensitivity reaction can manifest with **hypotension, tachycardia, bronchospasm, urticaria, angioedema**, and in severe cases, cardiovascular collapse. - Prophylactic antihistamines and corticosteroids are often administered to minimize this risk.

Q: Trendelenburg's operation is done for

primary varicose veins. ***primary varicose veins*** - **Trendelenburg's operation** is the classical surgical procedure for **primary varicose veins of the lower limb** - It involves **high ligation of the long saphenous vein** at the saphenofemoral junction - Named after Friedrich Trendelenburg (1844-1924), this was historically the standard treatment for varicose veins - Modern variations include **flush ligation** and stripping of the saphenous vein - Now often replaced by minimally invasive techniques like **endovenous laser ablation (EVLA)** and **radiofrequency ablation (RFA)** *varicocele* - **Varicocele** is treated by operations like **Ivanissevich procedure**, **Palomo's operation**, or **laparoscopic varicocelectomy** - These involve ligation of the **testicular/gonadal veins**, not the saphenous vein - There is no established surgical technique for varicocele called "Trendelenburg's operation" - The confusion may arise from Trendelenburg's contributions to various surgical fields *deep vein thrombosis with varicose veins* - **Deep vein thrombosis (DVT)** is an acute condition requiring **anticoagulation therapy**, not surgical intervention like Trendelenburg's operation - Management focuses on preventing **pulmonary embolism** and post-thrombotic syndrome - Varicose veins may coexist but are addressed separately after DVT treatment *arteriovenous fistula* - **Arteriovenous fistula** represents an abnormal connection between artery and vein - Treatment involves **surgical repair**, **embolization**, or observation depending on etiology - This is unrelated to Trendelenburg's operation for venous insufficiency [Practice more Surgery PYQs on OnCourse]

Q: Which of the following does not alter the T stage in breast cancer?

Nipple retraction. ***Nipple retraction*** - Nipple retraction, while a significant clinical sign that can indicate an underlying malignancy, does **not alter the T stage** (tumor size and extent) of breast cancer. - It is considered a local sign of tumor proximity or involvement but does not classify the tumor into a T4 category according to AJCC TNM staging. - Nipple retraction may be seen with various T stages and is **not a criterion for upstaging**. *Pectoral muscle involvement* - **Important note**: Involvement of the **pectoralis muscle alone does NOT alter T stage** according to current AJCC TNM classification. - Only **chest wall involvement** (ribs, intercostal muscles, serratus anterior) qualifies as **T4b**. - This is a common point of confusion, but pectoralis muscle is **not considered chest wall** for staging purposes. *Skin ulceration* - **Skin ulceration** directly reflects tumor invasion through the skin of the breast. - This finding is a criterion for classifying the tumor as **T4b**, indicating advanced local disease. - Clearly **alters the T stage** regardless of tumor size. *Peau d'orange* - **Peau d'orange** (orange peel appearance) is caused by obstruction of dermal lymphatics by tumor cells, leading to **skin edema**. - This sign is a criterion for classifying the tumor as **T4b** (edema of the skin including peau d'orange). - Clearly **alters the T stage** and indicates advanced local disease.
