Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is an extremely rare complication of infectious diseases. A rare case of brucellosis complicated by syndrome of inappropriate secretion of antidiuretic hormone (SIADH) cholestasis and pericardial involvement is reported. A 27-year-old woman was admitted for fever, abdominal pain, and scleral icterus. Her medical history reveale...

1. The effects of adrenalectomy on the adenylate cyclase--adenosine 3':5'-cyclic monophosphate (cyclic AMP) system of rat renal medulla were examined to evaluate the mechanism of the impaired water diuresis in glucocorticoid deficiency. 2. Concentrations of cyclic AMP in medullary tubules from adrenalectomized rats were significantly higher than in the tubules from control animals both in the p...

A 15-year-old boy, who was diagnosed with Alport syndrome and end-stage renal disease, received a renal transplant from a living-related donor. On postoperative day 1, his daily urine output was 10,000 mL despite normal graft function. His laboratory findings including urine, serum osmolality, and antidiuretic hormone levels showed signs similar to central diabetes insipidus, so he was administ...

An 81-year-old woman with a medical history of hypertension, hypercholesterolemia, childhood pulmonary tuberculosis, bronchiectasis, and depression presented at our hospital reporting dyspnea on slight exertion, cough, and yellowish expectoration of 4 days’ duration. On physical examination, the patient was alert, oriented, afebrile, and normotensive. Bilateral wheezing was noted on auscultatio...

The effect of morphine anaesthesia on plasma antidiuretic hormone levels was studied in seven adult patients. Measurements of ADH showed no significant change with morphine and 50 per cent nitrous oxide. Significant elevation occurred with surgical stimulation as previously reported. Changes in urine flow with high doses of morphine are then not ADH related.

The hyponatraemia common in decompensated cirrhosis arises in part from secretion of antidiuretic hormone attributed to a decrease in effective blood volume. Baroreceptors send inhibitory impulses to the midbrain and hypothalamus through the vagus and glossopharyngeal nerves. Since vagal neuropathy often occurs in chronic alcoholism, this might theoretically contribute to the inappropriate secr...

The efficacy of oral urea in producing a sufficiently high osmotic diuresis was tested in seven patients with the syndrome of inappropriate secretion of antidiuretic hormone. In all patients urea corrected the hyponatraemia despite a normal fluid intake. Five patients were controlled (serum sodium concentration greater than 128 mmol(mEq)/1) with a dose of 30 g urea daily, and two with 60 g dail...

Current knowledge on prostaglandin biosynthesis is reviewed, centering on how PGs participate in the regulation of vascular tone and the prevention of platelet deposition on endothelial surfaces. Discussion includes review of the vasoactivity of the PG endoperoxides, thromboxane, prostacyclin, and prostaglandin E2; prostaglandin-catabolizing enzymes; polyunsaturated fatty acid precursors; nutri...

Cerebral salt-wasting syndrome (CSWS) is a rare disease characterized by a extracellular volume depletion and hyponatremia induced by marked natriuresis. It is mainly reported in patients who experience a central nervous system insult, such as cerebral hemorrhage or encephalitis. The syndrome of inappropriate antidiuretic hormone secretion is a main cause of severe hyponatremia after hematopoie...
