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.
Which of the following cell types show abnormal function when there is a history in a young adult of multiple arm and leg fractures following minor falls, with a slight weakness of facial muscles on the left, mild anemia, and with generalized bony widening with partial obliteration of marrow spaces?
1) Granulocytic stem cells
2) Megakaryocytes
3) Plasma cells
4) Osteoclasts
General Pathology Answer: 4
Osteoclasts show abnormal function in conditions leading to multiple fractures, as they are responsible for bone resorption.
Trigeminal neuralgia
1. Does not disturb the patient during sleep
2. Can be treated with NSAIDs
3. Always bilateral in distribution
4. Is a hereditary condition
Oral Pathology
Answer: 1
Trigeminal neuralgia does not disturb the patient during sleep.
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.
A patient comes with emotional problems, increased salivation, pallor of oral mucosa and a grayish blue discolouration of the gingival. These findings are most consistent with a clinical impression of
1. Cherubism
2. Cretinism
3. Pierre-Robin syndrome
4. Lead poisoning
Oral Pathology
Answer: 4
The findings of emotional problems, increased salivation, pallor, and grayish-blue discoloration of the gingiva are consistent with lead poisoning.
Extensive cellulitis is known as:
1. Phlegm
2. Phlegmon
3. Cellulitis majora
4. Cellulitis prima
Pathology Answer: 2
Extensive cellulitis is most accurately described by the term "phlegmon
Phlegm is a thick, viscous substance produced by the respiratory tract,
especially during a respiratory infection, which can be coughed up from the
lungs or expelled from the nose. It is primarily composed of mucus, dead cells,
and other substances.
Phlegmon is a term that is closely related to extensive cellulitis. It refers
to a severe form of cellulitis where the infection has spread deeply into the
subcutaneous tissues and is accompanied by significant inflammation, including
the presence of pus and necrosis. Phlegmon is characterized by intense pain,
swelling, redness, and warmth in the affected area. This condition often
requires aggressive medical management, including intravenous antibiotics and
surgical drainage if an abscess forms. It is an advanced and severe stage of
cellulitis that can lead to systemic infection if not treated properly.
In sickle cell trait, number of bands found in Hb-
1) 2
2) 1
3) 4
4) 5
General Pathology
Answer: 1
In sickle cell trait, the number of bands found in hemoglobin is typically 2, representing both HbA and HbS.
All of the following statements about the typical feature of a periapical
granuloma are true EXCEPT
1) It consists of proliferating granulation tissue
2) It can form only if the periapical bone is resorbed
3) It shows evidence of local antibody production
4) It results from immunologically mediated tissue damage
Oral Pathology Answer: 2
Periapical granulomas were diagnosed as well-circumscribed periapical
radiolucency measuring less than 1.5 cm in diameter, periapical cysts were
characterized by well-defined periapical radiolucency with sclerotic borders
measuring greater than 1.5 cm, and periapical abscesses were characterized by
ill-defined periapical radiolucency with diffuse margins.
While bone resorption can occur in the presence of a periapical granuloma, it
is not a prerequisite for its formation. A periapical granuloma can develop in
response to pulp necrosis or infection without necessarily requiring bone
resorption to occur first. The granuloma can form as a reaction to the
inflammatory process, regardless of the state of the surrounding bone.
