Q: What is correct regarding this suture?

Monofilament. ***Monofilament*** - **Monofilament** sutures consist of a single strand, which minimizes tissue drag and reduces the risk of harboring **bacteria** and subsequent wound infection. - This structure is typical for materials like **Prolene** (Polypropylene) and **Nylon**, prized for their low friction and use in delicate or contaminated fields. *Non absorbable* - This describes the **fate** of the suture (remaining permanently in the body) but not its structure; non-absorbable sutures can be either **monofilament** (e.g., Nylon) or multifilament (e.g., Silk). - While many important sutures are non-absorbable, it is a property independent of whether the suture is single-stranded. *Braided multifilament* - This refers to sutures made of multiple intertwined strands, which is the structural opposite of a **monofilament**. - Multifilament sutures typically offer better knot security but have increased tissue drag and potential for **capillarity** (wicking action). *Collagen derived* - This refers to the material source, specifically **catgut** (made from sheep or cow intestine), which is an absorbable natural material. - Catgut is absorbable and rapidly loses its tensile strength; 'monofilament' describes the physical form and is not exclusive to this biologic material.

Q: A 56-year-old man presents with the following pathology shown in the image, which of the following is correct?

Lipodermatosclerosis/eczema can occur. ***Lipodermatosclerosis/eczema can occurs*** - The image suggests features of **chronic venous insufficiency (CVI)**, including skin discoloration (hyperpigmentation/hemosiderin deposition) and induration, which are classic features leading to **lipodermatosclerosis** and **venous eczema** (C4 changes in CEAP classification). - Lipodermatosclerosis involves inflammation and fibrosis of the skin and subcutaneous fat in the gaiter area due to prolonged **venous hypertension**. *Sclerotherapy is the best treatment* - Sclerotherapy is typically indicated for **small varicose veins** or **telangiectasias**. - For CVI causing advanced skin changes (like lipodermatosclerosis), the best initial treatment is usually **compression therapy** and addressing the source of reflux (e.g., endovenous ablation). *Telangiectasia is rare* - **Telangiectasias** (spider veins) are very common in patients with CVI and often represent the earliest visible sign of **venous disease** (C1 in CEAP classification). - The presence of more advanced skin changes (like those shown) indicates significant venous hypertension, often accompanied by microcirculatory changes including telangiectasia. *No possibility of venous ulcer* - The changes seen (hyperpigmentation and probable underlying induration/atrophy) are stages C4/C5 of the CEAP classification, which are **immediate precursors** to or associated with **venous leg ulcers** (C6). - Venous hypertension is the underlying cause for both the skin changes and the development of **venous ulcers**, making the possibility very real in this patient.

Q: A 3-year-old child was brought to OPD with complaint of dysuria and ballooning on micturition and examination as given below, what is the diagnosis?

True phimosis. ***True phimosis*** - The image shows a severely narrowed, pinhole-like preputial opening, coupled with **dysuria** and **ballooning on micturition**, which are hallmark symptoms of symptomatic or **pathological phimosis**. - **Ballooning** occurs because the tight foreskin traps urine before it can exit, confirming significant distal urinary outflow obstruction. *Balanitis xerotica obliterans* - Although BXO is a leading cause of pathological phimosis, this diagnosis is reserved for cases showing characteristic **sclerotic, white, atrophic skin changes** around the meatus, which are absent in the image. - BXO typically develops secondary to a chronic inflammatory process and is often considered when the phimosis is **acquired** rather than purely developmental. *Recurrent balanoposthitis* - Balanoposthitis is an inflammation of the glans and prepuce, typically presenting with **erythema, swelling, and discharge**. - While repeated episodes can lead to **scarring and acquired phimosis**, the primary and most concerning diagnosis here is the resulting anatomical obstruction (phimosis) that is causing symptoms. *Recurrent urinary tract infections* - **Recurrent UTIs** are a potential complication of significant true phimosis, resulting from urine stasis and poor hygiene. - However, the symptoms described, especially **ballooning on micturition**, directly indicate the presence of urethral **outflow obstruction**, which is the diagnosis.

Q: A 30-year-old female was brought to the emergency room after a fire. On examination, full-thickness burns and deep partial-thickness burns were present involving the lower limb circumferentially. A procedure was performed to relieve vascular compromise. Identify the procedure?

Escharotomy. ***Escharotomy*** - Performed for **full-thickness (circumferential)** burns to relieve pressure caused by the rigid, constricting **eschar** (necrotic tissue). - Indicated when there are signs of **compartment syndrome** or impaired distal circulation (e.g., absent pulses, cyanosis) in the affected limb. *Debridement* - Involves removing dead, contaminated, or foreign material from a wound to promote healing. - While necessary for complex burns, simply debridement does not address the acute vascular compromise caused by circumferential full-thickness burns. *Excised to healthy tissue* - Refers to **tangential** or **fascial excision** of the burn wound, an operative procedure typically done under general anesthesia for definitive wound management. - This is performed later for wound bed preparation, not an immediate, bedside procedure to restore circulation and prevent limb loss like **escharotomy**. *Early skin grafting* - The definitive procedure used to close the wound after it is excised and prepared. - Cannot be performed until severe vascular constriction is relieved and the wound bed is adequately prepared, making it a later step in management.
