A 23-year-old female presented with jaundice and pallor for 2 months. Her peripheral blood smear shows the presence of spherocytes. The most relevant investigation to arrive at a diagnosis is -
1) Reticulocyte count
2) Osmotic fragility test
3) Coombs test
4) Tests for PNH
General Pathology
Answer: 3
The osmotic fragility test is the most relevant investigation for diagnosing hereditary spherocytosis, as it assesses the red blood cells' ability to withstand osmotic stress.
When taking radiographs for children, exposure should be reduced by what percentage of that of adults?
1. 25 %
2. 50 %
3. 75 %
4. Same exposure
Oral Pathology
Answer: 2
Exposure for children should be reduced by 50% compared to adults.
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.
Commonest type of Basal cell carcinoma is -
1. Ulcerated
2. Cystic
3. Morphoeic
4. Pigmented
Pathology
Answer: 1
1. Noduloulcerative Basal Cell Carcinoma: This is the most common subtype of
BCC, making up about 60-70% of all cases. It typically appears as a slowly
growing, round to oval, pearly or translucent nodule with a central ulceration
that may bleed or ooze. The borders of the lesion are often not well-defined and
may have a rolled, pearly edge with telangiectasias (small, dilated blood
vessels).
2. Cystic Basal Cell Carcinoma: This subtype presents as a round, dome-shaped
lesion with a cystic or fluid-filled center. It is less common than the
noduloulcerative type, and it may be mistaken for a benign cyst or epidermoid
cyst.
3. Morphoeic Basal Cell Carcinoma: Also known as sclerosing or morpheaform BCC,
this type is characterized by a slowly growing, ill-defined, firm, plaque-like
lesion that can infiltrate deeply into the skin. It may have a whitish, waxy
appearance with a scar-like texture. Morphoeic BCC tends to be more aggressive
and can be challenging to diagnose due to its subtlety.
4. Pigmented Basal Cell Carcinoma: This is a less common variant of BCC,
accounting for approximately 6-15% of cases. It presents with pigmentation in
the lesion, which can be brown, blue, or black. The presence of pigment can make
it look similar to melanoma, another type of skin cancer, so a biopsy is often
necessary to confirm the diagnosis.

4. Stevens-Johnson syndrome
Oral Pathology
Answer: 1
Facial paralysis with drooping of the mouth and excess lacrimation is characteristic of Bell's palsy.
All of the following may occur in achondroplasia, except
1. Short and thickened muscular extremities
2. Dwarfism
3. The elbows often cannot be folded
4. Bowed legs and small hands
Oral Pathology
Answer: 3
In achondroplasia, the elbows often cannot be folded is not true; they can be folded.
Adamantinoma is
1. A tumour from embryonal cell of developing teeth
2. Also known as ameloblastoma
3. Is a complication of dengigerous cyst
4. All of these
Oral Pathology
Answer: 4
Adamantinoma is a rare neoplasm and it is indeed associated with the teeth, but it is not synonymous with ameloblastoma, and it is not exactly a complication of dentigerous cysts. However, since all options are somewhat inaccurate or misleading, your answer indicates that you may be looking for the one best fitting choice.
