Detection of xanthochromia in cerebrospinal fluid.
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 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...

متن کاملPseudo-Froin's syndrome, xanthochromia with high protein level of cerebrospinal fluid
provided the original work is properly cited. CC Froin’s syndrome is characterized by marked cerebrospinal fluid (CSF) xanthochromia (yellow discoloration of the CSF) and hypercoagulability due to increased protein content. The cause of the high protein content of the spinal fluid is meningeal irritation and inflammation. Pseudo-Froin's syndrome has been described as stagnation of the CSF dista...

Enterobius vermicularis is a nematod of large intestine in man. Extra intestinal localization of this parasite is rare. A 60 year old man was admitted to the hospital with the clinical manifestation of meningitis. In laboratory examination of cerebrospinal fluid (C.S.F), the appearance was red, Albu-min level was high and the glucose showed normal value. Haematoxylin and Eosin stained slides pr...
