Viscosity is the resistance to flow of a fluid and it is the only property of a fluid that will affect
its flow through a system of valveless tubing (surface tension will affect the opening and …

Abstract IT HAS LONG been assumed that a high cerebrospinal fluid protein concentration
adversely affects the performance of shunts. There is little experimental evidence to support …

Dermal sinuses penetrating the dura are important in that they may be complicated by CNS
infection, and this complication can be prevented by early surgery. Although well recognised …

A 65-year-old man had a perimesencephalic subarachnoid haemorrhage with normal
angiography initially. After a rebleed 5 days later, a repeat angiogram revealed a pea-like …

A prospective study was performed to determine whether the popular opinion that a high
CSF protein concentration increases the risk of shunt complications is true. Ninety-five …

OBJECTIVE To assess the quantity and nature of the proteins that adsorb to hydrocephalus
shunt catheters after implantation, and to determine whether sufficient could accumulate to …

For the past 50 years the pterional craniotomy has been the standard approach for anterior
circulation aneurysms. However, this is a major procedure. As the trend is towards minimally …

CSF surface tension has received little study, and yet it will effect the pressure at which shunt
valves operate, and by influencing the degree of hydrophobicity (contact angle) will alter the …

BACKGROUND: Infundibula are frequently regarded as incidental anatomical variants that
are of no pathogenetic significance. CASE CESCRIPTION: A 51-year-old man presented …

BACKGROUND--Prosthetic infections are a major problem, requiring complex and lengthy
management. The role of blood proteins in the pathogenesis of implant infection has been …
