Increased gonadal production of oestrogen is seen in:
- A. Third trimester of pregnancy
- B. Congenital adrenal hyperplasia
- C. Polycystic ovarian disease
- D. Testicular feminization syndrome
Correct Answer: C
Rationale: Polycystic ovarian disease, also known as polycystic ovary syndrome (PCOS), is a common endocrine disorder characterized by increased levels of androgens (male hormones) and disrupted estrogen production in the ovaries. The hormonal imbalance seen in PCOS leads to increased gonadal production of estrogen. This condition is often associated with symptoms such as irregular menstrual cycles, infertility, acne, and excess facial or body hair growth. In contrast, the other options do not typically involve increased gonadal production of estrogen as seen in PCOS.

A person with acromegaly usually has:
- A. prognathism and large fleshy lips.
- B. hypoglycemia.
- C. a growth hormone deficiency.
- D. protruding eye balls.
Correct Answer: A
Rationale: Acromegaly is a hormonal disorder that results from the overproduction of growth hormone (GH) in adulthood. One of the key physical characteristics associated with acromegaly is the enlargement of facial features. People with acromegaly often develop prognathism, which is a condition where the lower jaw protrudes forward, leading to a prominent lower face. Additionally, they may have large fleshy lips due to the soft tissue swelling that occurs as a result of excess GH. Other common signs of acromegaly include enlarged hands and feet, thickened skin, and joint pain.
Cushing's syndrome does not give rise to:
- A. Hirsutism
- B. Peripheral neuropathy
- C. Purple striae
- D. Acne
Correct Answer: B
Rationale: Cushing's syndrome is a disorder caused by prolonged exposure to high levels of cortisol hormone. While Cushing's syndrome can manifest with a variety of symptoms, peripheral neuropathy is not a typical feature of this condition. Cushing's syndrome is commonly associated with symptoms such as hirsutism (excessive hair growth), purple striae (skin stretch marks that are purple in color), and acne due to the hormonal imbalances it creates. Peripheral neuropathy, which involves damage to the peripheral nerves leading to symptoms like numbness, tingling, and weakness in the extremities, is not a characteristic symptom of Cushing's syndrome.
Persistent muscular weakness is characteristic of:
- A. Conn's syndrome
- B. Acromegaly
- C. Hyperparathyroidism
- D. Myxoedema
Correct Answer: D
Rationale: Persistent muscular weakness is characteristic of myxoedema, which is severe hypothyroidism. Myxoedema can lead to general weakness and fatigue, as thyroid hormones play a crucial role in controlling metabolism and energy production in the body. Other symptoms of myxoedema include cold intolerance, weight gain, dry skin, and hair loss. Conn's syndrome (hyperaldosteronism) is characterized by hypertension and low potassium levels, not persistent muscular weakness. Acromegaly is a condition resulting from excess growth hormone production, leading to enlarged body parts and metabolic changes but not specifically muscular weakness. Hyperparathyroidism is associated with high levels of parathyroid hormone, which can lead to bone weakening and calcium imbalance, but it is not typically a primary cause of muscular weakness.
Features of hypoglycaemia do not include:
- A. Drenching sweat
- B. Tachycardia
- C. Tachypnoea
- D. Brisk jerk
Correct Answer: D
Rationale: Hypoglycemia is characterized by a low blood sugar level, which can lead to various symptoms. The features of hypoglycemia typically include drenching sweat, tachycardia (increased heart rate), and tachypnea (rapid breathing). A brisk jerk, on the other hand, is not a typical feature of hypoglycemia. Symptoms such as confusion, dizziness, shakiness, hunger, weakness, and irritability are more commonly associated with hypoglycemia than a brisk jerk.
Which of the followings is consistent with neuropathic pain due to diabetes:
- A. Burning pain
- B. Electric shock quality
- C. Tingling
- D. All of the above
Correct Answer: D
Rationale: Neuropathic pain due to diabetes can present with a variety of symptoms, including burning pain, electric shock quality, and tingling sensation. These symptoms are commonly reported by individuals with diabetic neuropathy, which is the most common form of neuropathic pain associated with diabetes. The combination of these sensations can significantly impact the quality of life for those living with diabetes and neuropathic pain. Therefore, all of the above options are consistent with neuropathic pain due to diabetes.
