Amyloidosis most commonly occurs in:

# Amyloidosis most commonly occurs in:

A. Kidney

B. Spleen

C. Liver

D. Heart

The correct answer is A. Kidney.

Amyloidosis of the kidneys is most common and most serious because of ill effects on renal function. Kidneys affected by amyloidosis may be normal sized or enlarged; the cut surface is pale, waxy and translucent. Amyloidosis of spleen has two patterns - Sago spleen and lardaceous spleen.

CSF rhinorrhea is found in:

# CSF rhinorrhea is found in:

A. Frontal bone fracture

B. Zygomatico maxillary fracture

C. Nasoethmoidal fracture

D. Condylar fracture

The correct answer is C. Nasoethmoidal fracture.

CSF rhinorrhea is seen in nasoethmoidal, Le Fort II and Le Fort III fractures, associated with comminuted cibriform plate of ethmoid. Tramline effect and halo on pillow effect are diagnostic signs of CSF rhinorrhea.

# Wounds which are clean, uninfected and surgically incised, with edge of wounds approximated by sutures heal by:

A. Primary intention

B. Secondary intention

C. Cauterization

D. All of the above

The correct answer is A. Primary intention.

Clean, uninfected, surgically incised wounds that are approximated by surgical sutures heal by primary intention. Infected, open large wounds that are not approximated by surgical sutures heal by secondary intention. Healing after flap surgery is by primary intention where as gingivectomy, gingivoplasty and extraction socket heal by secondary intention.

# Tensile strength of wound becomes normal after:

A. 6 weeks

B. 4 month

C. 6 month
