All of the following statements about idiopathic thrombocytopenic purpura are true except
1. It is associated with platelet-specific autoantibodies
2. It causes a prolonged bleeding time
3. It is often controllable by immunosuppressive treatment
4. It causes more prolonged haemorrhage than haemophilia
Oral Pathology Answer: 4
It is associated with platelet-specific autoantibodies:
This statement is true. ITP is characterized by the
presence of autoantibodies that specifically target and destroy platelets,
leading to thrombocytopenia (low platelet count).
It causes a prolonged bleeding time: This statement is true.
In ITP, the low platelet count results in a prolonged bleeding time, as
there are fewer platelets available to form a clot.
It is often controllable by immunosuppressive treatment:
This statement is true. ITP can often be managed with
immunosuppressive therapies, such as corticosteroids, intravenous
immunoglobulin (IVIG), or other immunosuppressive agents, to help increase
platelet counts.
It causes more prolonged hemorrhage than hemophilia:
This statement is not true. While both ITP and hemophilia
can lead to bleeding, the mechanisms are different. Hemophilia is a clotting
factor deficiency, which can lead to more severe and prolonged bleeding
episodes, especially after trauma or surgery. In contrast, ITP primarily
affects the number of platelets rather than the clotting factors. Therefore,
the bleeding in hemophilia can be more severe and prolonged compared to that
in ITP.
Tobacco usage has been associated with
1. Hyperkeratosis
2. Erythema
3. Ulceration
4. None of the above
Oral Pathology
Answer: 1
Tobacco use, particularly smoking, is known to cause various oral lesions, including hyperkeratosis, which is a thickening of the outer layer of the skin or mucous membranes. This can manifest as leukoplakia or other forms of keratosis in the oral cavity. While tobacco can also lead to erythema and ulceration, hyperkeratosis is the most directly associated condition.

3. Accelerated periodontal diseases
4. Xerostomia
Oral Pathology
Answer: 3
Accelerated periodontal diseases is not a complication of irradiation of the mouth.
