Brain edema accounts for much of the morbidity and mortality associated with common neurological conditions such as head trauma, brain tumors, stroke and liver failure. Treatment options are limited to osmotic agents such as mannitol, surgical decompression, and other maneuvers, none of which
Hyperosmolality occurs when there are defects in the two major homeostatic mechanisms required for water balance-thirst and arginine vasopressin (AVP) release. In this situation hypotonic fluids are lost in substantial quantities causing depletion of both intracellular and extracellular fluid
Extravascular lung water (idQw1) is measured in vivo from the difference in mean transit times, computed by extrapolating the dilution curves, of two indicators, one freely diffusible, the other confined to the intravascular space. Using 3H2O it has been shown that idQw1 is smaller than the amount
The process of brain edema formation has been studied extensively at the macroscopic level. In contrast, little is known about water fluxes and volume changes at the cellular level in the initial phase of brain edema. Insight in these "microscopic" events could pave the way for more efficient
OBJECTIVE
To look for intrinsic changes in renal tubular water and sodium metabolism in idiopathic edema (IE), independent of the underlying hormonal and vascular defects.
METHODS
Prospective controlled study in patients with edema referred to a nephrology clinic.
METHODS
Ten female patients with IE
Exercise in the water offers several physiological advantages to the pregnant woman. The hydrostatic force of water pushes extravascular fluid into the vascular spaces, producing an increase in central blood volume that may lead to increased uterine blood flow. This force is proportional to the
With recent emphasis on increased water intake during exercise for the prevention of dehydration and exertional heat illness, there has been an increase in cases of hyponatremia related to excessive water intake. This article reviews several recent military cases and three deaths that have occurred
