Crew haircut appearance in X-ray skull and Gamna Gandy bodies are seen in -
1) G-6-PD deficiency
2) Hodgkin's lymphoma
3) Hereditary spherocytosis
4) Sickle cell anaemia
General Pathology
Answer: 4
Crew haircut appearance in X-ray skull and Gamna Gandy bodies are associated with sickle cell anemia due to chronic hemolysis and bone marrow hyperplasia.
The following protein defects can cause hereditary spherocytosis except -
1) Ankyrin
2) Palladin
3) Glycophorin C
4) Anion transport protein
General Pathology
Answer: 3
Glycophorin C is not associated with hereditary spherocytosis; it is a sialoglycoprotein found in the red blood cell membrane, while ankyrin, palladin, and anion transport protein are involved in the structural integrity of the membrane.

A wound which Was sutured attains:
1. Normal tensile strength after 6 months
2. 70-80% of tensile strength of unwounded skin which may persist for life
3. 100% tensile strength of unwounded skin after 9 months
4. 100% of tensile strength can be achieved if sutures were of nylon or vicryl
Pathology Answer: 2
The newly formed collagen in the scar tissue is arranged differently compared to the organized collagen fibers in the unwounded skin, leading to a weaker structure. The 70-80% tensile strength is typically what is seen in well-healed sutured wounds. This remaining deficit is because scar tissue is less elastic and more prone to dehiscence (reopening) under tension compared to normal skin.
