NEETMDS - 3 Questions

A surgeon removed section of tissues how would he confirm that cut margin doesn't contain any suspicious tissue intraoperatively?

1) Punch biopsy
2) Brush biopsy
3) Frozen section
4) Exfoliative cytology

๐Ÿ“ Explanation:

The frozen section procedure is the examination of tissue to make a rapid microscopic diagnosis of a specimen while surgery is taking place. It is often used in oncological surgery to inform the surgeon if the surgical margin is clear of residual cancer, or if residual cancer is present at the surgical margin. 


The technical name for this procedure is cryosection. The report given by the pathologist is usually limited to a "benign" or "malignant diagnosis, and communicated to the surgeon operating via intercom. When operating on a previously confirmed malignancy, the main purpose of the pathologist is to inform the surgeon if the surgical margin is clear of residual cancer, or if residual cancer is present at the surgical margin


Advantages of frozen section biopsy:
If more tissue is needed to make an accurate diagnosis, the surgeon is able to obtain an additional sample, avoiding a second operation.
If the tissue is determined to be cancerous and is amenable to surgery, the mass can b removed at that time
If the tissue is determined to be benign (not cancerous), then the mass may not always need to be removed and the surgery can end.

Appearance of ulnar sesamoid bones in hand occurs
1) At onset of pubertal growth spurt
2) Birth
3) At the end of pubertal spurt
4) At the prepubertal sport

๐Ÿ“ Explanation:

The appearance of the ulnar sesamoid bone is a reliable indicator of skeletal maturity and typically occurs at the onset of the pubertal growth spurt. This event is a key marker used in orthodontics and pediatrics to assess a child's developmental stage.

Positive nitrogen balance is seen in:
1) Pregnancy
2) Kwashiorkar
3) Fever
4) Marasmus

๐Ÿ“ Explanation:

Positive nitrogen balance occurs when the intake of nitrogen (protein) is greater than its excretion, indicating net protein anabolism (building up tissues). This is a normal physiological state during periods of growth, such as childhood, adolescence, and pregnancy, where new tissues are being synthesized. Kwashiorkor and marasmus are forms of malnutrition characterized by negative nitrogen balance (protein catabolism), as is a prolonged fever state.
