Lumbar puncture (LP) still has an important role to play in the diagnosis of subarachnoid hemorrhage. Although computed tomography (CT) scanning has replaced LP as the investigation of first choice, within 24 h of ictus 5% of cases will show no evidence of hemorrhage on CT scanning; this percentage is as high as 50% by 1 week, 30% after 2 weeks, and 0% after 3 weeks (1). By definition, xanthoch...

متن کاملDetection of Herpes Simplex Virus Infection in Cerebrospinal Fluid
ABSTRACT Background and Objective: Herpes simplex encephalitis is a life-threatening consequence of the central nervous system (CNS) infection with Herpes simplex virus (HSV). Although it is a rare disease, mortality rates reach 70% in the absence of therapy and only a minority of individuals can return to normal function. The aim of this study was to d...
متن کاملWhy human color vision cannot reliably detect cerebrospinal fluid xanthochromia.
BACKGROUND Visual assessment of cerebrospinal fluid (CSF) for xanthochromia (yellow color) is practiced by the majority of laboratories worldwide as a means of diagnosing intracranical bleeds. METHODS Colorimetric and spectrophotometric analysis of CSF samples for recognizing the presence of bilirubin either in low concentrations or in the presence of hemolysed blood. RESULTS The experiment...
