Disorders of sodium and water balance are one of the commonly encountered problems while managing patients with neurological diseases. Managing such problems are challenging because the pathophysiology behind these disorders are complex and poorly understood and treatment of the injured brain itself

These patients are also at a higher risk of the complications of hyponatremia such as brain injury, the main result of acute symptomatic hyponatremia and associated with significant morbidity and mortality. Severe hyponatremia (i.e., a serum sodium concentration <125 mmol/L) ), if unrecognized in

Fluid therapy is aimed to compensate for fasting which is required for surgery, to meet the ongoing fluid losses and to maintain electrolyte balance during surgery. Fluid deficit of a healthy child who is not fed parenterally may be estimated by multiplying hourly maintenance requirement for fluid

Hyponatremia occurs frequently in patients with acute brain injury in the days to weeks following the acute injury, and may contribute to adverse outcome (1). In addition, hyponatremia can aggravate neurologic dysfunction, complicate neurological assessments, and contribute to neurologic symptoms

This study will be conducted during the fifth stage of a 6-stage ultramarathon foot race that covers a total of 250 kilometers. Data will be collected during four separate events over the course of the coming year. All races are run by the RacingThePlanet™ 4-desert race series with locations

This is a cross-over study. Totally 15 participants will be randomized (or other number later determined by power test). The duration of the study is 9 days that will include 3 visits and screening visit before starting the study. Screening (day -1) Inclusion criteria are fulfilled before

Previous work has demonstrated the pathophysiological role of arginine-vasopressin (AVP) in ischemic stroke. The mechanism of action of AVP is by 3 receptor subtypes: V1a, V1b and V2 expressed in brain, pituitary gland, myocardium, vasculature and kidneys. The role of the vasopressin receptors V1a

Patients with advanced cirrhosis frequently develop dilutional hyponatremia due to impairment of their renal ability to eliminate solute-free water. Although the pathophysiology of this disorder is multifactorial, an increased hypersecretion of arginine vasopressin (AVP) is a major factor. The

The investigators have demonstrated that a normal FEurate in a nonedematous hyponatremic patient is highly consistent with the diagnosis of reset osmostat (RO). Since as much as 36% of patients with SIADH have RO, the investigators will evaluate these patients by either noting dilute urines in

BACKGROUND: For the pathogenesis of inner ear hydrops resulting in Meniere's attacks, plasma vasopressin elevation due to stress and V2 receptor overexpression in the inner ear could be essential as a basis of this disease. In the present study, we'd like to find the effective and feasible way to

Methods: Between 1998 and 2006, we enrolled and assigned 105 intractable Meniere's patients to examine plasma vasopressin during remission of vertigo attacks (controls: 30 patients with chronic otitis media). Using the real-time PCR method, we examined V2R mRNA expression in the endolymphatic sac in

Intravascular volume and serum osmolality are tightly regulated by a balance of various neurohumoral mediators. In critical illness, these regulatory mediators may be modified by disease or treatment, either benefiting or harming the patient. Such regulatory mediators of intravascular volume and
