OBJECTIVE Cerebrospinal fluid (CSF) production rates influence shunt design and the care of children with hydrocephalus. Measurement of hourly CSF output through external ventricular drainage (EVD) reflects the CSF production. In the present study, hourly CSF outputs in children with hydrocephalus were measured while they were treated with EVD and correlated with the age, sex and body weight of...

Objective. This paper aims to assess 25(OH)D levels in Italian children and adolescents identifying risk factors for 25(OH)D deficiency and to evaluate whether a normal 25(OH)D value can be restored in 25(OH)D-deficient patients. Methods. We evaluated 25(OH)D levels in 679 Italian children and adolescents (≤10, 11-20, 21-30, and >30 ng/mL were defined as severe deficiency, deficiency, insuffici...

OBJECTIVE Our study aimed to investigate the nutritional vitamin D status of school children aged 9-15 years and white-collar workers in Zhejiang province, and evaluate the efficacy of low-dose-oral vitamin D supplementation in both populations. METHODS We conducted a prospective controlled trial during March 2014 to November 2015, comparing the efficacy of vitamin D supplements (400 IU/day) ...

The penetration of cefoxitin into cerebrospinal fluid (CSF) was studied in 25 patients with purulent meningitis treated with antibiotics other than cefoxitin. Each patient received three 2-g doses of cefoxitin at 6-h intervals. Blood and CSF samples were obtained before and at 2, 4, or 6 h after the first and third doses. CSF cefoxitin concentrations were found in all patients and varied betwee...

BACKGROUND Daptomycin, a lipopeptide antibiotic, could be an alternative to vancomycin for treatment of pneumococcal meningitis. We determined the activity of daptomycin versus vancomycin, with dexamethasone as an adjuvant, in a murine model of pneumococcal meningitis. METHODS Ninety-six 25-30 gram mice were inoculated intracisternally with serotype 3 Streptococcus pneumoniae modified by the ...

Poor penetration of vancomycin into Central Nervous System (CNS) can lead to treatmentfailure. The aim of this study was to evaluate and compare CSF concentration and serumpharmacokinetics of high dose vancomycin by continuous infusion vs. intermittent infusion inpost neurosurgical meningitis patients. Twenty patients were divided into two groups. Patientsin intermittent infusion group received...

Macrophage colony-stimulating factor (CSF-1) increases the tissue invasive potential of the CSF-1 receptor-bearing lung carcinoma cell lines A549 and Calu-1 by increasing the number of endogenously bound urokinase-type plasminogen activators (u-PA)s on these cells. CSF-1, at concentrations which optimize invasion of A549 and Calu-1 cells into human amnion membranes (250 ng/ml), maximally augmen...

A highly sensitive and rapid liquid chromatography tandem mass spectrometry (LC-MS/MS) method has been developed to measure the levels of the antitubercular drug rifampicin (RIF) in human plasma and cerebrospinal fluid (CSF). The analyte and internal standard (IS) were isolated from plasma and CSF by a simple organic solvent based precipitation of proteins followed by centrifugation. Detection ...
