BACKGROUND Ventriculoperitoneal shunt infection remains a significant problem. The introduction of antibiotic-impregnated shunt (AIS) systems in the prevention of shunt infection may represent a potential advance; however, there are no randomized controlled trials to establish a robust evidence-based practice. Previously published single-institution cohort(More)
BACKGROUND The cause and mechanism of most cases of sudden unexpected death in infancy (SUDI) remain unknown, despite specialist autopsy examination. We reviewed autopsy results to determine whether infection was a cause of SUDI. METHODS We did a systematic retrospective case review of autopsies, done at one specialist centre between 1996 and 2005, of 546(More)
BACKGROUND Intrauterine infection may play a role in preterm delivery due to spontaneous preterm labor (PTL) and preterm prolonged rupture of membranes (PPROM). Because bacteria previously associated with preterm delivery are often difficult to culture, a molecular biology approach was used to identify bacterial DNA in placenta and fetal membranes. (More)
OBJECT The aim of this study was to establish whether microbiological contamination at the time of shunt insertion can be detected and used to predict the likelihood of subsequent shunt infection. METHODS A prospective study of pediatric patients undergoing primary shunt insertion was undertaken. Following the protocol devised for this study, three swab(More)
BACKGROUND Chlamydophila pneumoniae has been postulated as an aetiological agent in the pathophysiology of multiple sclerosis. Previous studies show conflicting results. OBJECTIVE To investigate patients with multiple sclerosis and other neurological diseases for evidence of past or present infection with C pneumoniae. METHODS 19 patients with multiple(More)
Prevalence of healthcare associated infections remains high in patients in intensive care units (ICU), estimated at 23.4% in 2011. It is important to reduce the overall risk while minimizing the cost and disruption to service provision by targeted infection control interventions. The aim of this study was to develop a monitoring tool to analyze the spatial(More)
PURPOSE The aim of this study is to report the efficacy of long subcutaneous tunnelling of external ventricular drains in reducing rates of infection and catheter displacement in a paediatric population. METHODS In children requiring external ventricular drainage, a long-tunnelled drain was placed and managed according to a locally agreed guideline. End(More)
OBJECT Infection after both primary and revision shunt surgeries remains a major problem in pediatric neurosurgical practice. Antibiotic-impregnated shunt (AIS) tubing has been proposed to reduce infection rates. The authors report their experience with AIS catheters in their large pediatric neurosurgery department. METHODS The authors conducted a(More)
BACKGROUND Increasingly, Onyx is used for endovascular embolization of aneurysms and arterio-venous malformations. Although reports in the literature on the use of Onyx are favourable, there have been so far no reports on the central nervous system (CNS) infection rate after embolisation with Onyx and no recommendations as to the management of these(More)
