Growth hormone (GH)

The uncontrolled hormone production in acromegaly and gigantism is most often the result of

hildren who have midline craniocerebral defects, nystagmus, retinal abnormalities, and other midline or midfacial abnormalities (e.g., cleft lip or palate) should be evaluated for deficiencies in
The most significant regulator of antidiuretic hormone (ADH) release is
Osmotic pressure of plasma
When damage occurs to the antidiuretic hormone (ADH)-producing cells in the hypothalamus from head trauma, intracranial tumors, or neurosurgery, what disorder is suggested by a large diuresis of very dilute urine?
The pathology of syndrome of inappropriate antidiuretic hormone (SIADH) secretion, leading to dilution of serum and an excess of water relative to solute, produces
Hemoconcentration and falsely high hemoglobin
Changes in urine osmolality seen in syndrome of inappropriate antidiuretic hormone (SIADH) secretion cause
ncreased water retention without sodium
An enlarged thyroid gland produces a colloid goiter when
Lack of iodine prevents T4 and T3 but without stopping thyroglobulin formation
In adrenocortical insufficiency, such as Addison disease, the most severe manifestations are the result of
An insufficient amount of circulating cortisol
Cushing syndrome differs from Cushing disease in that the term Cushing syndrome is used only to describe
Hypercortisolism manifestations, regardless of cause
f the cause of hypercortisolism is an adrenal tumor, which option is indicated?
Unilateral removal of the affected gland
A severely hypertensive patient presents with the classic triad of headache, tachycardia, and diaphoresis, and laboratory tests show excessive circulating catecholamine levels. Which rare, but treatable, disorder is suspected?
The origin of congenital adrenal hyperplasia occurs when circulating cortisol levels
are insufficient to provide negative feedback to the anterior pituitary gland.
