MDS PREP

Which of the following facilitates comparison between different radiation
1. Rad
2. Rem
3. Roentgen
4. Quality factor

Oral Pathology Answer: 2

Rem facilitates comparison between different types of radiation.

The common feature of cherubusm, hyperparathyroidism and aneurysmal bone cyst is
1. All affect soft tissues only
2. All contain multinucleated giant cells histologically
3. All are of pituitary origin
4. All require aggressive therapy

Oral Pathology Answer: 2

All these conditions contain multinucleated giant cells histologically.

Sickle cell trait patient do not have manifestations as that of Sickle cell disease, because-
1) 50% HbS is required for occurrence of sickling
2) HbA prevents sickling
3) 50% sickles
4) HbA prevents polymerization of Hbs

General Pathology Answer: 1

HbA prevents sickling in sickle cell trait patients because the presence of normal hemoglobin (HbA) reduces the proportion of HbS, preventing polymerization.

Which of the following is most sensitive to radiation induced cancer
1. Nerves
2. Female breast
3. Thyroid
4. Skin

Oral Pathology Answer: 2

The female breast is most sensitive to radiation-induced cancer.

Which of the following conditions is characterized by the triad of medullary carcinoma of the thyroid, pheochromocytoma, and oral and intestinal ganglioneuromatosis?
1) MEN I
2) MEN II
3) MEN III
4) MEN IIA

General Pathology Answer: 3

MEN II is characterized by the triad of medullary carcinoma of the thyroid, pheochromocytoma, and oral and intestinal ganglioneuromatosis.

The epithelium which covers a healed ulcer is derived from

1. undifferentiated mesenchymal cells of the ulcer

2. intact epithelium at the ulcer margin

3. transformation of fibroblasts to epithelial cells

4. endothelial cells via the blood stream

Oral Pathology Answer: 2

The epithelium which covers a healed ulcer is derived from intact epithelium at the ulcer margin

Radiation injury to the haemopoietic system of the bone marrow occurs when the whole body exposure ranges between
1. 50-100 rads
2. 200-1000 rads
3. 1000-5000 rads
4. 10,000 rads to more

Oral Pathology Answer: 2

Radiation injury to the hematopoietic system occurs when whole body exposure ranges between 200-1000 rads.

Sickle cell mutation is -
1) Point mutation
2) Select mutation
3) Frame shift mutation
4) Nonsense mutation

General Pathology Answer: 1

Sickle cell mutation is a point mutation, specifically a single nucleotide substitution in the ?-globin gene.
