BACKGROUND We are often left with the differential diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH) versus hypovolemic hyponatremia. It is difficult to tell who will respond to isotonic saline infusion and who will not, if the urine sodium value is not completely suppressed (>10 mEq/L). AIM To examine the diagnostic accuracy of the urine sodium value. DESIGN A r...

Abstract Background and Aims Hyponatremia (<135mEq/L) is the most common electrolyte disorder observed in clinical practice, associated with increased hospital admissions mortality. One of its causes syndrome inappropriate antidiuretic hormone secretion (SIADH). In chronic SIADH, urea considered as a therapeutic possibility among other measures; however, use not widespread due to few stu...

SYNDROME OF INAPPROPRIATE ANTIDIURETIC HORMONE SECRETION ASSOCIATED WITH SMALL CELLS LUNG CANCER WITH BONE METASTASIS (ABSTRACT): A patient with a bone metastasis developed a asymptomatic hyponatremia, with all features of the Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH). The event was interpreted as a consequence of ADH release due to to primary cancer located in the lungs ...

A 5-year-old female Chihuahua was presented for acute collapse. Laboratory examinations showed markedly elevated levels of hepatobiliary enzymes. Empiric antibiotic therapy for bacterial infection of the liver was ineffective. The clinical signs worsened with the development of hyponatremia with hypoosmolality and elevated urine sodium levels. The dog was suspected of having acute cholangiohepa...

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...

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...

Dysregulation of the neuroendocrine system is a frequent complication after traumatic brain injury (TBI). Symptoms of these hormonal abnormalities might be subtle and thus easily ignored. Hyponatremia usually indicates underlying disorders that disrupt fluid homeostasis. In most patients with TBI, hyponatremia is a feature of the syndrome of inappropriate antidiuretic hormone (SIADH) secretion ...

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a potential cause of hyponatremia of the central nervous system (CNS). Although SIADH has been reported to be associated with many other central nervous disorders, its association with neuromyelitis optica (NMO) or NMO spectrum disorders are rare. NMO is a demyelinating disorder characterized by optic neuritis and transvers...

Serum potassium concentration was normal (greater than or equal to 3.6 mmol/l) in 29 of 32 patients with the syndrome of inappropriate antidiuretic hormone excess (SIADH) associated with a bronchogenic carcinoma. In 11 of the patients there was no significant change in serum potassium concentration after correction of the syndrome, by fluid restriction. Hypokalaemia is thus an uncommon finding ...
