Hypothyroidism is a condition where the thyroid gland does not produce sufficient thyroid hormones.
Causes of hypothyroidism include autoimmune disease, surgery, radiation therapy, antithyroid drugs, and thyroiditis.
Decreased metabolic rate, decreased body heat production, and hypercalcemia are three concepts related to hypothyroidism.
Clinical manifestations of hypothyroidism include obesity, anorexia, bradycardia, cold intolerance, constipation, slowness in physical and mental reaction, brittle nails, and irregular menstruation.
Management of hypothyroidism includes monitoring vital signs, a low-calorie, high-fiber diet, providing a warm environment during cold weather, and pharmacological treatment with T3, T4, or thyroglobulin.
Myxedema coma is a severe complication of hypothyroidism characterized by hypothermia, unconsciousness, and the need for intravenous thyroid hormone, correction of hypothermia, maintenance of vital functions, and treatment of the underlying cause.
Hyperpituitarism is a condition of excessive growth hormone production, also known as Acromegaly and Gigantism.
Acromegaly occurs after epiphyseal closure and causes thickening and transverse growth, with onset typically between the ages of 30-50 and a slow development.
Gigantism occurs before epiphyseal closure and affects infants and children, with abrupt development.
Clinical manifestations of Acromegaly include an enlarged jaw, thickened tongue, enlarged and weakened hands, oily and leathery skin, and disturbance in sleep.
Clinical manifestations of Gigantism include muscular hypertonia, exophthalmos, a highly arched palate, and disturbance in sleep.
Causes of hyperpituitarism include a benign tumor of the pituitary gland and 60% to 80% of pituitary tumors.
Treatment for hyperpituitarism includes surgery, medication to inhibit GH synthesis, and a salt-restricted diet.
Hypopituitarism is marked by deficient secretion of the anterior pituitary hormones, leading to dwarfism, metabolic dysfunction, sexual immaturity, and growth retardation.
Causes of hypopituitarism include tumors, congenital defects, pituitary ischemia, partial or total hypophysectomy, and radiation therapy.
Diabetes insipidus is a condition of deficient production of vasopressin, leading to large volumes of dilute urine and intense thirst.
Causes of diabetes insipidus include surgical treatment of a brain tumor, nonsurgical brain tumors, traumatic brain injury, infections of the nervous system, post-hypophysectomy, failure of renal tubules to respond to ADH, and the use of specific medications.
Management of diabetes insipidus includes replacing ADH, ensuring adequate fluid replacement, and identifying and correcting the underlying intracranial pathology.
