I would like to thank Drs Carraccio, Blotny, and Fisher1 for their recent study on cerebrospinal fluid (CSF) analysis. However, the presented data do not define the CSF absolute neutrophil count (ANC), upper limit of ANC, and standard deviation of ANC for their patients. I would like to review this potentially valuable information. The authors referred to the study by Rodewald et al2 who found nucleated and segmented leukocyte counts to be important CSF indicators.

I find it necessary to comment on the paper "Cephalosporium Meningitis" (Pediatrics, 44:749, 1969) in order to emphasize a word of caution to physicians who may encounter patients under circumstances similar to those described by Drs. Papadatos, Pavlatou, and Alexiou. The patient reported was a newborn infant who on day 15 of life became irritable, listless, and refused feedings. In the absence of abnormal physical findings, the cerebrospinal fluid was examined and found to be slightly xanthochromic with 20 white blood cells per cu mm, and with normal chemical constituents.

Background and Purpose: Patients with posterior reversible encephalopathy syndrome (PRES) sometimes undergo analysis of cerebrospinal fluid (CSF) to exclude alternative diagnoses. This study’s objectives were to describe the CSF characteristics in patients with PRES and to identify clinical and radiologic findings associated with distinct CSF abnormalities. Methods: We identified a retrospective cohort of patients with PRES. We compared clinical and radiographic characteristics of those who did versus did not undergo lumbar puncture, described the observed range of CSF findings, and analyzed clinical and radiographic features associated with specific CSF abnormalities. Results: A total of 188 patients were included. Patients with (n = 77) and without (n = 111) CSF analysis had similar clinical and radiographic characteristics. Cerebrospinal fluid protein was elevated in 46 (60%) of 77, with median CSF protein 53 mg/dL (upper limit of normal 45 mg/dL). Protein elevation was significantly associated with radiographic severity ( P = .0058) but not with seizure, time from symptom onset, radiographic evidence of diffusion restriction, or contrast enhancement. Five (7%) patients had elevated CSF white blood cells, all of whom had infarction and/or hemorrhage on neuroimaging, and 4 of whom had eclampsia. Conclusion: The CSF of most patients with PRES shows a mild protein elevation commensurate with radiographic severity. Cerebrospinal fluid pleocytosis may mark a distinct subtype of PRES with predisposition toward infarction and/or hemorrhage. These findings help clinicians interpret CSF findings in these patients and generate new hypotheses about the pathophysiology of this syndrome.

Rabbit is widely used as an experimental animal model in infectious and non-infectious diseases. The haematologic data can be helpful in evaluating the health status of animals over time. The aim of this study was to determine the levels of red blood cells (RBC), white blood cells (WBC) and differential leukocyte counts in 5 nulliparous and 5 multiparous females, i.e. in young and older animals, at mating and at delivery. The values of RBC did not change with age, but WBC and lymphocytes decreased with age, a -33% and a -60% less in multiparous females than nulliparous ones. Monocytes count was double at delivery than at mating. In conclusion, aging on the immune system is manifested as reduction in production of mature lymphocytes and as a result, older females would not respond to immune challenge as robustly as the young ones. Physiological status is only related to production of monocytes.

Abstract BACKGROUND Reference intervals are vital for interpretation of laboratory results. Many existing reference intervals for cerebrospinal fluid total protein (CSF-TP) are derived from old literature because of the invasive nature of sampling. The objective of this study was to determine reference intervals for CSF-TP using available patient data. METHODS Twenty years of hospital database information was mined for previously reported CSF-TP results. Associated demographic, laboratory, and clinical diagnosis (International Classification of Diseases 9/10 codes) details were extracted. CSF-TP results included 3 different analytical platforms: the Siemens Vista 1500, Beckman Lx20, and Roche Hitachi 917. From an initial data set of 19591 samples, the following exclusion criteria were applied: incomplete data, white blood cells (WBCs) >5 × 106/L, red blood cells (RBCs) >50 × 106/L, and glucose <2.5 mmol/L. Patient charts were reviewed in detail to exclude 60 different conditions for which increases in CSF-TP would be expected. A total of 6068 samples were included; 63% of the samples were from females. Continuous reference intervals were determined using quantile regression. Age- and sex-partitioned intervals were established using the quantile regression equation and splitting age-groups into 5-year bins. RESULTS CSF-TP showed a marked age dependence, and males had significantly higher CSF-TP than females across all ages. CSF-TP results from the 3 different instruments and manufacturers showed small (approximately 0.04 g/L), but statistically significant, differences. CSF-TP showed weak, but again statistically significant, correlation with WBC and RBC but was independent of serum total protein and creatinine. CONCLUSIONS The age dependence of CSF-TP supports that age-partitioned reference intervals will be more accurate than a single cutoff, particularly in patients with advancing age.

OBJECTIVE: Follistatin (FS) is the specific binding protein of activin and expression of both factors is regulated by inflammatory agents. Therefore, FS concentrations were determined in cerebrospinal fluid (CSF) of patients with bacterial and viral meningitis or multiple sclerosis (MS), as well as in the CSF of patients without meningial inflammation or autoimmune diseases. Furthermore, a mouse pneumococcal meningitis model was used to localise the cellular sources of FS in brains of normal and meningitic mice. METHODS: FS concentrations in CSF were determined by ELISA; FS in mice was localised by in situ hybridisation and immunohistochemistry. RESULTS: FS concentrations were > or =0.4 microg/l in 22 of 66 CSF samples of meningitis patients versus 2 of 27 CSF samples from patients with multiple sclerosis (P<0.05) and 2 of 41 CSF specimen from patients without neuroinflammatory diseases (P<0.01). In the CSF of patients with meningitis, the concentration of FS was correlated with total protein (P<0.005) and lactate concentrations (P<0.05), but not with leukocyte counts, interval between onset of disease and CSF analysis, or clinical outcome. The CSF-to-serum ratios of FS and albumin also correlated significantly (P<0.0005). In some patients with meningitis the CSF-to-serum ratios suggested that the elevated FS in CSF did not originate from serum alone. FS was localised in mice brains to neurones of the hippocampus, dentate gyrus, neocortex, and to the choroid plexus. Analyses of brains and other organs from uninfected and infected animals sacrificed 6-36 h after infection did not reveal any obvious differences in the distribution and intensity of FS mRNA and protein expression. CONCLUSIONS: The concentration of FS in humans is elevated during meningitis. In some patients the increase is caused by a release of FS from brain into CSF. Data from the mouse meningitis model suggest that increased CSF concentrations of FS in meningitis appear not to be accompanied by an elevated number of cells containing FS mRNA or protein in the brain.

Symptomatic Management

A 42-year-old healthy man sought care for transient episodes of neurologic deficits followed by severe headache. The first episode began with left hand weakness, numbness, and dysarthria, followed approximately 1 hour later by a right temporal headache. His symptoms spontaneously resolved after 8 hours. He had a second episode 2 days later manifested by confusion and bilateral lower extremity numbness, again followed by severe headache with symptoms resolving within 12 hours. A total of 8 episodes occurred over 3 weeks, each lasting 8 to 24 hours, with spontaneous resolution each time. His most recent episode occurred during cerebral angiography. Cerebrospinal fluid evaluation showed opening pressure, 190 mm H2O; white blood cells, 205/μ‎L, 97% lymphocytes; protein, 95 mg/dL; and glucose, 40 mg/dL. Electroencephalography demonstrated right greater than left generalized slowing, with increased-voltage rhythmic delta wave activity, in the frontal regions predominantly. Conventional cerebral angiography findings were normal, but the test appeared to provoke the patient’s previous episode. Neurologic examination was normal after his most recent episode resolved, and no further episodes were reported. This case highlights a typical presentation of transient headache and neurologic deficits with cerebrospinal fluid lymphocytosis. Because the disorder was self-limited, treatment was aimed at symptomatic management of headache. In this case patient with a secure diagnosis of headache and neurologic deficits with cerebrospinal fluid lymphocytosis and stereotypical episodes limited to 3 months after the initial presentation, additional testing was not indicated. Headache and neurologic deficits with cerebrospinal fluid lymphocytosis is a rare, self-limited, benign condition with migrainelike headache episodes accompanied by transient neurologic deficits usually lasting more than 4 hours, with some deficits lasting more than 24 hours.

Route Of Delivery

Cerebrospinal fluid (CSF) fills the subarachnoid space, spinal canal, and ventricles of the brain. CSF is enclosed within the brain by the pial layer, ependymal cells lining the ventricles, and the epithelial surface of the choroid plexus, where it is largely produced. Choroid plexus is present throughout the ventricular system with the exception of the frontal and occipital horns of the lateral ventricle and the cerebral aqueduct. The vascular smooth muscle and the epithelium of the choroid plexus receive both sympathetic and parasympathetic input. In an adult, CSF is normally acellular. A normal spinal sample may contain up to 5 white blood cells (WBCs) or red blood cells (RBCs). CSF allows for a route of delivery and removal of nutrients, hormones, and transmitters for the brain.

A study of the red blood cells, hemoglobin, blood platelets, and the total and individual white blood cells was made on 180 male rabbits of known age and representing fifteen standard breeds. An attempt was made to eliminate or bold constant such variables as age, sex, season, time of examination, technical errors, food, housing, and disease. The mean, variance of the mean, and standard deviation were calculated for each breed sample and for the group as a whole. An analysis of the variance showed that the variation between the breed samples was significantly greater than the variation within the breed samples for the red blood cells, hemoglobin, blood platelets, total white blood cells, basophiles, eosinophiles, and lymphocytes per cubic millimeter and in per cent and the neutrophiles in per cent. No significant variations were detected in the monocytes except when the breeds were divided into heavy and light breeds. No variation in the neutrophiles per cubic millimeter was detected; a large number of the breeds had exactly the same mean neutrophile level. Characteristic blood formulae were found for the various breed samples having an adequate numerical representation. It was concluded that the varying blood formulae could not be explained on any other, except an hereditary (genetic) basis.
