We present the case of a patient with meningitis due to pneumococcus admitted to our department with subsequent hyponatraemia and polyuria. The patient was a 64-year-old woman operated on for closed mastoidectomy with tympanoplasty due to chronic otitis media, with hearing loss in the left ear 3 months after admission. The patient presented with pain and suppuration in the left ear lasting for ...

BACKGROUND In patients with severe central nervous system (CNS) diseases, life-threatening hyponatremia results from two main causes: the syndromes of inappropriate secretion of antidiuretic hormone (SIADH) and cerebral salt wasting (CSW). Clinical manifestations of the two conditions may be similar but their pathogeneses are fundamentally diverse. Distinguishing SIADH from CSW is based on the ...

Hyponatremia and increased urine output after calvarial remodeling have been noted in pediatric patients with craniosynostosis. If not treated properly, patients develop hypoosmotic conditions that can lead to cerebral edema, increased intracranial pressure, and collapsed circulation. Postoperative hyponatremia after central nervous system surgery is considered as the syndrome of inappropriate ...

Report of a Case. A 75-year-old man presented with a 3-week history of worsening ataxia following blunt head trauma in a motor vehicle crash 1 month earlier. His history included uncomplicated type 2 diabetes mellitus and hypertension, managed with rosiglitazone, 4 mg/d, and ramipril, 2.5 mg/d. The patient was confused and had marked truncal ataxia. Central venous pressure was low at 3 mm Hg, i...

Hyponatremia secondary to the Syndrome of Inappropriate Anti-Diuretic Hormone (SIADH) secretion is commonly observed in patients with various neurological disorders. Cerebral Salt Wasting (CSW) resulting in hyponatremia is also an infrequent occurrence in some patients with neurological disorders. Confusion in differentiating CSW from SIADH may arise since both results in similar electrolyte di...
