Exophthalmos may occur in children with what diagnosis?

Choice A rationale:

Hypoparathyroidism is not associated with exophthalmos. Hypoparathyroidism is a condition where the parathyroid glands produce insufficient parathyroid hormone, leading to low calcium levels in the blood. This condition doesn't directly affect the thyroid gland or cause exophthalmos.

Choice B rationale:

Exophthalmos, also known as protruding or bulging eyes, is a classic symptom of hyperthyroidism. Hyperthyroidism is a condition where the thyroid gland produces excessive amounts of thyroid hormones. These elevated hormone levels can lead to a variety of symptoms, including increased metabolism, weight loss, nervousness, and protruding eyes due to inflammation of the eye muscles and tissues behind the eye.

Choice C rationale:

Hyperparathyroidism involves the overactivity of the parathyroid glands, leading to excessive production of parathyroid hormone (PTH) and elevated calcium levels in the blood. While elevated calcium levels can have various effects on the body, exophthalmos is not a typical manifestation of hyperparathyroidism. The condition is more commonly associated with bone and kidney issues.

Choice D rationale:

Hypothyroidism, the underproduction of thyroid hormones by the thyroid gland, is not linked to exophthalmos. Instead, hypothyroidism is known for causing symptoms such as fatigue, weight gain, cold intolerance, and slow heart rate. Exophthalmos is a characteristic sign of hyperthyroidism, not hypothyroidism.

The correct answer is Choice B: Dry skin.

Choice A rationale:

Diarrhea is not a common clinical manifestation of juvenile hypothyroidism. Hypothyroidism is characterized by an underactive thyroid gland, leading to a decrease in metabolic activity. Symptoms of hypothyroidism include fatigue, weight gain, cold intolerance, constipation, and dry skin, but not diarrhea.

Choice B rationale:

Dry skin is a common clinical manifestation of juvenile hypothyroidism. The decreased thyroid function results in a slower metabolic rate, which can lead to dry and coarse skin due to reduced oil production. This symptom is often seen in hypothyroid patients.

Choice C rationale:

Insomnia is not a common clinical manifestation of juvenile hypothyroidism. Hypothyroidism usually leads to fatigue and excessive sleepiness rather than insomnia.

Choice D rationale:

Accelerated growth is not a common clinical manifestation of juvenile hypothyroidism. In fact, the opposite is true. Hypothyroidism in children can lead to growth retardation due to the decreased metabolic rate and altered hormonal balance.
