What is the primary prevention strategy for pulmonary embolism in patients with heart failure and atrial fibrillation?
(1) Antiplatelet therapy
(2) Anticoagulation therapy with warfarin
(3) Physical prophylaxis with compression stockings
(4) Thrombolytic therapy
Patients with heart failure and atrial fibrillation are at high risk for pulmonary embolism due to venous thrombosis and intra-cardiac thrombus formation. The primary prevention strategy for these patients is anticoagulation therapy with warfarin, as it reduces the risk of thrombus formation and embolization. Warfarin is effective in preventing stroke and systemic embolism in patients with non-valvular atrial fibrillation and is also beneficial in the context of heart failure.
Malherbe"s epithelioma characterised by all except
1) Benign calcifying epithelioma
2) Common in adults
3) Solitary, hard tumours
4) Mostly on the neck, face, arms
Oral medicine
Answer: 2
Malherbe's epithelioma, also known as calcifying epithelioma, is typically a benign tumor that is more common in children and young adults rather than adults. It is characterized by solitary, hard tumors that are often found on the neck, face, and arms. The other options accurately describe the characteristics of Malherbe's epithelioma.
What condition is NOT associated with osteoporosis?
1) Hypogonadism
2) Hyperthyroidism
3) Fluorosis
4) Hyperparathyroidism
Fluorosis is associated with osteosclerosis, not osteoporosis. It leads to increased bone density due to excessive deposition of fluoride.
What is the genetic pattern of inheritance for Huntington's disease?
(1) Autosomal recessive
(2) Autosomal dominant
(3) X-linked recessive
(4) X-linked dominant
Huntington's disease is an autosomal dominant disorder. This means that a single copy of the defective gene, inherited from either parent, is sufficient to cause the disease. Each offspring of an affected individual has a 50% chance of inheriting the gene and developing the disease.
What is the characteristic gait abnormality seen in patients with advanced Huntington's disease?
1) Festinating gait
2) Spastic gait
3) Ataxic gait
4) Choreic gait
The characteristic gait abnormality in Huntington's disease is the choreic gait, which is disjointed and poorly coordinated with a "dancing" quality.
What is the primary function of the aortic valve?
(1) To prevent backflow of blood from the aorta into the left ventricle during diastole
(2) To prevent backflow of blood from the pulmonary artery into the right ventricle during diastole
(3) To prevent backflow of blood from the pulmonary vein into the left atrium during systole
(4) To prevent backflow of blood from the left ventricle into the left atrium during systole
The aortic valve is located between the left ventricle and the aorta and is responsible for preventing the backflow of blood into the left ventricle during systole, ensuring that blood is efficiently pumped out of the heart into the systemic circulation.
In which organism is echinococcosis most commonly found?
(1) Liver
(2) Lungs
(3) Brain
(4) Heart
Echinococcosis is a parasitic infection caused by the larvae of Echinococcus granulosus. The most common site for these larvae to form cysts is the liver.

Scaly or irritated skin that may crack easily.
Other Symptoms:
Restless legs syndrome, which can cause discomfort and an urge to
move the legs.
Pain in the legs or calves after prolonged sitting or standing.
Complications of Varicose Veins
Severe Symptoms:
Increased leg swelling and pain, especially after long periods of
inactivity.
Risk of developing deep vein thrombosis (DVT), which can lead to
serious complications if blood clots form.
Skin Conditions:
Lipodermatosclerosis, a condition that causes inflammation and
hardening of the skin.
Venous ulcers, which are painful sores that can develop due to poor
circulation.
