ABSTRACT
BACKGROUND: External cerebrospinal fluid (CSF) diversion via a drain is associated with a variable risk of associated infections which cause significant morbidity. AIM: To establish whether simple interventions can reduce the incidence of such infections at a single centre. METHODS: A retrospective review of all patients undergoing an external CSF diversion procedure was carried out to determine the historical rate of infection. Following an institutional protocol which included standards on drain insertion, care, sampling and antibiotic prescribing a prospective study was carried out to observe whether infection rates had changed and which factors continued to predict drain-related infections. FINDINGS: Retrospective analysis identified 234 procedures in 159 patients over a two-year period. There were 54 drain-related infections, a rate of 21.5 per 1000 drainage days. Duration of CSF drainage [odds ratio (OR) = 1.15, P < 0.05] and the number of CSF samples taken per drain (OR = 5.98, P < 0.05) were independently associated with infection. In the prospectively gathered phase, 132 procedures were recorded in 107 patients over a one-year period. There were 18 infections, a rate of 13.7 per 1000 drainage days. The only independent prognostic factor was duration of CSF drainage (OR = 1.20, P < 0.05). Coagulase-negative staphylococci were the most commonly isolated type of organism in both series. CONCLUSION: Ensuring drains are removed promptly as soon as CSF diversion is no longer required may reduce the rate of nosocomial infections in this population despite multiple confounding factors. Institutional guidelines may promote best practice in this regard.

We report two patients with spinal epithelioid hemangioendothelioma (EH), an uncommon vascular, potentially malignant tumour. Neurological signs, diagnostic images, surgical techniques and complications, histology and the role of adjuvant therapy are discussed. Primary manifestation of EH of the vertebral column is rare. Thorough preoperative clinical and radiological workup, radical surgical excision, and close postoperative follow-up are recommended.

The implementation of the two-week wait initiative for cancer referrals in the NHS has had a major impact on outpatient services. A low clinical detection rate among GPs for neurological cancer has resulted in a large number of urgent referrals with a low yield of positive diagnoses. We have devised a strategy for minimizing the impact on outpatient clinics: patients are scanned prior to clinical review and those with normal scans are referred back to the GP without a clinic appointment. Out of 69 referrals of suspected CNS cancer made in 2003, 61 were scanned and six resulted in a positive diagnosis. The equivalent of 10 clinics was saved, and an increased speed of diagnosis and treatment was achieved with no compromise in patient care. Our study illustrates the consequences of the 2-week wait initiative on the neurosurgical service, and proposes an effective and safe solution.
