Twenty children from 2 months to 7 years (mean age 2.74 years +/- 1.62) diagnosed to have tuberculous meningitis (TBM) were evaluated for serial serum sodium levels and osmolality of cerebrospinal fluid (CSF), serum and urine on admission and the results compared with 20 age and nutritionally matched controls, and these investigations repeated on day 3 and day 10. Mean serum sodium levels (130....

Hyponatremia is a common electrolyte disorder in cancer patients and has been associated with poor prognosis. A frequent cause of cancer-related hyponatremia is the syndrome of inappropriate antidiuretic hormone (SIADH). This study was a post hoc subgroup analysis of the SALT-1 (Study of Ascending Levels of Tolvaptan in Hyponatremia) and SALT-2 clinical trials. Hyponatremic subjects with SIADH ...

Recently, chronic hyponatremia, even mild, has shown to be associated with poor quality of life and high mortality. The mechanism by which hyponatremia contributes those symptoms, however, remains elucidated. Syndrome inappropriate secretion antidiuretic hormone (SIADH) is a primary cause hyponatremia. Appropriate animal models are crucial for investigating the pathophysiology SIADH. A rat mode...

Olfactory neuroblastoma (ONB) is an uncommon neuroendocrine sinonasal cancer associated by many authors to ectopic production of several biologically active substances. We report a case of a 31-year-old male patient who presented with idiopathic syndrome of inappropriate secretion of antidiuretic hormone (SIADH). During diagnostic work-up, a CT scan of the head was performed and an ethmoidal ON...

Although the syndrome of inappropriate ADH secretion (SIADH) has many causes, principally pulmonary, central nervous system or neoplastic disease, and drugs, patients may present with SIADH in whom the etiology is not readily evident. We measured serum ADH levels in such an individual in both the eunatremic and water-loaded states and found levels to be undetectable despite failure to dilute th...

The current approach to the diagnosis and treatment of hyponatremia is in a state of flux, largely because of an unresolved controversy regarding the relative prevalence of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and cerebral salt wasting, or preferably renal salt wasting (RSW). The recent awareness that symptoms are now being attributed to even mild hyponatremia...

BACKGROUND Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a common cause of hyponatremia in hospitalized patients and is often described in patients with small-cell carcinoma of the lung. In this report, we described both Castleman's disease and lymphoma coexisting in one patient with SIADH. CASE PRESENTATION A 70-year-old Chinese woman with a history of diabetes mellitus...

BACKGROUND Cerebral cavernous malformations (CCMs, also known as cavernous hemanigiomas) of the third ventricle are uncommon. Here, we present a rare case of a CCM that caused the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). CASE DESCRIPTION A 68-year-old man presented with acute-onset cognitive and memory disturbance. Endocrinological examinations revealed hyponatremi...

The fortuitous detection of SIADH is described in a patient receiving clomipramine therapy.

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the most common cause of euvolemic hypo-osmotic hyponatremia. There are several etiologies of SIADH including neuroendocrine tumor, pulmonary disease, infection, trauma, and medications. Here, we report a case of SIADH associated with a schwannoma involving the mediastinum in a 75-year-old woman who presented with nausea, vomit...
