Hyponatremia is a marker of different underlying diseases and it can be a cause of morbidity itself; this implies the importance of a correct approach to the problem. The syndrome of inappropriate antidiuresis (SIAD) is one of the most common causes of hyponatremia: it is a disorder of sodium and water balance characterized by urinary dilution impairment and hypotonic hyponatremia, in the absen...

To determine if concentration of plasma arginine vasopressin (AVP) is inappropriate for the plasma Na+ concentration in hyponatremic burned patients, we obtained 32 plasma samples from 20 patients with total burn size (TBS) 15 to 80% of body surface on or after postburn day (PBD) 4 in the morning following all-night recumbency. In the 25 samples (17 patients) with hyponatremia, AVP was elevated...

BACKGROUND Syphilis has increased in prevalence the United States by 72.7% from 2013 to 2017, with highest rates recorded men who have sex men. There is an incidence of syphilis patients a concomitant HIV infection, estimated at 77-fold increase. CASE REPORT This report documents unusual case neurosyphilis manifesting as syndrome inappropriate antidiuretic hormone secretion (SIADH) 56-year-old ...

BACKGROUND AND OBJECTIVES The existence and prevalence of cerebral salt wasting (CSW) or the preferred term, renal salt wasting (RSW), and its differentiation from syndrome of inappropriate antidiuretic hormone (SIADH) have been controversial. This controversy stems from overlapping clinical and laboratory findings and an inability to assess the volume status of these patients. The authors repo...

The purposes of this study were (i) to determine the prevalence of exercise-associated hyponatremia (EAH) in multi-stage ultra-marathoners and (ii) to gain more insight into fluid and electrolyte regulation during a multi-stage race. Body mass, sodium concentration ([Na⁺]), potassium concentration ([K⁺]), creatinine, urea, specific gravity, and osmolality in urine were measured in 25 male ultra...

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...

BACKGROUND Hyponatremia is the most common disorder of body fluid and electrolyte balance in clinical practice. It is associated with increased morbidity, mortality, and length of hospital stay. Little is known about the relationship between hyponatremia and HIV disease. It is thought that hyponatremia in HIV is associated with a syndrome of inappropriate ADH secretion (SIADH), volume depletion...

Erratum After publication of the original article [1], it came to the authors' attention that the given name of the first author was spelled wrongly, due to a misinterpreted author correction during proofing. The first author's name (Hiroto Nakano) is published correctly in this erratum. Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) associated with lateral medullary syndro...

Carbamazepine (CBZ) has been reported to have an antidiuretic action, though it is not known how it produces this effect. This is a well recognized complication of CBZ therapy in adults. However this syndrome has been rarely observed in childhood. We present an epileptic child with fluid overload due to CBZ treatment who was referred with chest pain and cardiomegaly. Our patient developed fluid...
