familial colloid cyst of the third ventricle is very rare. this is one of the two largest families reported and the first in which all affected members are siblings. one asymptomatic sister was found by screening, emphasizing the value of screening. a brother and two sisters from a family consisting of three brothers and three sisters who were diagnosed as having colloid cyst of the third ventr...

BACKGROUND In the past, several studies have compared different colloidal replacement solutions, whereby the focus was usually on the respective colloid. We therefore systematically studied the influence of the carrier solution's composition of five approved colloidal volume replacement solutions (Gelafundin, Gelafusal, Geloplasma, Voluven and Volulyte) on acid-base as well as electrolyte statu...

A conceptual model for colloid transport is developed that accounts for colloid attachment straining, and exclusion. Colloid attachment and detachment is modeled using first-order rate expressions, whereas straining is described using an irreversible first-order straining term that is depth dependent. Exclusion is modeled by adjusting transport parameters for colloid-accessible pore space. Fitt...

Hydroxyethyl starch (HES) solutions are synthetic non-protein colloid solutions used to treat hypovolemia. However, their use is not free from the risk of allergic reactions. A 42-year-old male was scheduled to undergo aortic-iliac-femoral bypass surgery for the treatment of arteriosclerosis obliterans. He had no history of allergy. Two hours after the start of surgery, and within minutes after...

purpose: the aim of this study was to investigate the feasibility and effectiveness of endoscopic neurosurgery for patients with third ventricular colloid cysts without ventriculomegaly. methods: seventy-one patients with third ventricular colloid cysts were identified and recruited to this study. eighteen of these patients did not have concomitant hydrocephalus and underwent primary endoscopic...

Absorption and extinction spectra of fractal and nonfractal small-particle composites are studied. General solutions of the coupled-dipole equations with the exact operator for the dipole interaction ~including the near-, intermediate-, and far-zone terms! are found and compared with those in the quasistatic approximation. Broadscale numerical simulations of optical spectra for clusters contain...
