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...

BACKGROUND Cerebral salt wasting syndrome (CSWS), syndrome of inappropriate antidiuretic hormone secretion (SIADH) and diabetes insipidus (DI) are frequently found in postoperative neurosurgery. PURPOSE To identify these syndromes following neurosurgery. METHOD The study included 30 patients who had been submitted to tumor resection and cerebral aneurysm clipping. Sodium levels in serum and...

BACKGROUND The care of patients with aneurysmal subarachnoid hemorrhage has evolved significantly with the advent of new diagnostic and therapeutic modalities. Although it is believed that these advances have contributed to improved outcomes, considerable uncertainty persists regarding key areas of management. OBJECTIVE To review selected controversies in the management of aneurysmal subarach...

OBJECTIVE To analyse 21-hydroxylase gene for 8 most common mutations in patients with salt-wasting type of congenital adrenal hyperplasia. METHODS Allele specific PCR performed on 8 salt-wasting CAH patients and their 23 healthy relatives. RESULTS Two patients were homozygous for 8 bp deletion in exon 3, while 6 patients were homozygous for intron 2 splice mutation. Mutant allele for splice...

In newborns and infants, dehydration and salt wasting represent a relatively common cause of admission to hospital and may result in life-threatening complications. Kidneys are responsible for electrolyte homoeostasis, but neonatal kidneys show low glomerular filtration rate and immaturity of the distal nephron, leading to reduced ability to concentrate urine. High extrarenal fluid losses often...

Excess aldosterone is an important contributor to hypertension and cardiovascular disease. Conversely, low circulating aldosterone causes salt wasting and hypotension. Aldosterone activates mineralocorticoid receptors (MRs) to increase epithelial sodium channel (ENaC) activity. However, aldosterone may also stimulate the thiazide-sensitive Na(+)-Cl(-) cotransporter (NCC). Here, we generated mic...
