Which of the following is the explanation for the laboratory findings in an alcoholic with chronic obstructive lung disease, secondary to cigarette smoking, of persistently lower serum levels than expected of theophylline which is being used as a bronchodilator, even though the drug is taken according to schedule?
1) Cirrhosis of the liver
2) Decreased absorption
3) Enhanced liver metabolism
4) Increased urinary clearance

False about cherubism
1. Unilocular lesion
2. Bilateral
3. Presence of giant cell
4. Delayed eruption of permanent teeth
Cherubism is not characterized by unilocular lesions; it is typically bilateral.
When treated with simple curettage which odontogenic tumour is most likely to recur
1) Complex odontoma
2) Compound odonotoma
3) Odentogenic myxoma
4) Ameloblastic fibroma
Oral Pathology
Answer: 3
Explanation: Odontogenic myxoma is known for its aggressive behavior and tendency to recur after treatment, including curettage. It is a benign but locally invasive tumor, and simple curettage often does not remove the entire tumor, leading to recurrence.
If a woman 22 weeks pregnant has ankle edema and proteinuria, the presence of which of the following would determine if she has preeclampsia?

1) Hyperparathyroidism
2) Primary hypoparathyroidism
3) Pseudohypoparathyroidism
4) Renal failure
The symptoms described are indicative of primary hypoparathyroidism, which can occur after surgical removal of the parathyroid glands.
Sickle cell anemia is precipitated when:
1) Oxygen tension goes down
2) Increased viscosity of blood is there
3) There is dehydration
4) All of the above
Pathology Answer: 4
Sickle cell disease results from mutation, or change, of certain types of hemoglobin chains in red blood cells (the beta hemoglobin chains).
When the oxygen concentration in the blood is reduced, the red blood cell assumes the characteristic sickle shape. This causes the red blood cell to be stiff and rigid, and stops the smooth passage of the red blood cells through the narrow blood vessels.
