Four anatomical patterns of hydrocephalus secondary to congenital Toxoplasma gondii infection were identified and characterized for infants enrolled in the National Collaborative Chicago-based Congenital Toxoplasmosis Study. Analysis of parasite serotype revealed that different anatomical patterns a

Hydrocephalus is a very common disease in developing countries. Congenital aqueductal obstruction and post-inflammatory hydrocephalus come on the top of the list of causes of hydrocephalus. Till the recent introduction of cranial endoscopy and despite their frequent complications, shunts were consid

OBJECTIVES: Most of our understanding of ventriculoperitoneal (VP) shunt blockage (ventricular end) is based on in vitro studies of blocked VP shunts. Not much information is available regarding the in vivo changes that occur in the tube and in the surrounding ventricle. The primary aim of our study

実験先天性水頭症モデルの病因,病態を検索し,ヒトの先天性水頭症における病態を考察した。実験モデルとして,遺伝形式をとるものとして水頭症ラットLEW/Jms系を,胎生期における薬剤投与によるモデルとして6-aminonicotinamide(6-AN)誘発水頭症ラットを用いた。両モデルともに胎生期における病理形態学的側面を検索した。その結果,先天性水頭症ラットLEW/Jmsでは一次的な中脳水道狭窄が …

… 　An unusual case of congenital hydrocephalus due to aqueductal stenosis is reported. … The first attempt of ventriculo-atrial shunt was effective only a short period because of obstruction of the ventricular catheter due to unusually high concentration of protein, in fact over 2 gm/dl, in ventricular fluid. …
