Maternal antibodies to Sarcocystis neurona are passively transferred from a seropositive mare to her foal in colostrum and can remain detectable by Western blot for up to 9 months of age, although most foals are seronegative by 6 months of age. Antibodies are detectable in CSF of neonatal foals from several days to age up to at least 3 months of age. Author’s address: Dept of Large Animal Clini...

An outbreak of Acinetobacter spp infection in the neonatal unit at Lok Nayak Hospital, New Delhi, India, is described. During a 6-month period, 68 strains of Acinetobacter baumannii were isolated from the blood and CSF of 47 neonates admitted to the intensive care unit. Diagnosis of clinically significant bacteremia was made in 36 patients. On environmental/personnel sampling, Acinetobacter spp...

PURPOSE This study was undertaken to determine the neuroprotective effect of granulocyte stimulating factor (G-CSF) on neonatal hypoxic-ischemic brain injury. MATERIALS AND METHODS Seven-day-old male newborn rat pups were subjected to 110 minutes of 8% oxygen following a unilateral carotid artery ligation. Apoptosis was identified by performing terminal deoxynucleotidyl transferase-mediated d...

Neurometabolic diseases diagnosed by cerebrospinal fluid (CSF) examination are GLUT1 deficiency, serine-deficiency syndromes, glycine encephalopathy, cerebral folate deficiency, neonatal vitamin-responsive epileptic encephalopathies, disorders of monoamine metabolism, and y-amino butyric acid (GABA) metabolism. We retrospectively analyzed and compared the demographic, clinical, laboratory, and ...

We describe dendritic cell progenitors within the CD34+ stem cell compartment in neonatal cord blood and identify growth factors contributing to their differentiation. Granulocyte-macrophage colony-stimulating factor (GM-CSF), although mainly promoting the growth and differentiation of monocyte-macrophages (mono-m psi s), also induced the differentiation of cells with the distinctive morphologi...

We performed unbiased, comprehensive immunophenotyping of cerebrospinal fluid (CSF) and blood leukocytes in 221 subjects referred for the diagnostic work-up of neuroimmunological disorders to obtain insight about disease-specific phenotypes of intrathecal immune responses. Quantification of 14 different immune cell subsets, coupled with the assessment of their activation status, revealed physio...

We evaluated the efficacy of non-competitive N-methyl-D-aspartate receptor antagonist MK-801 (dizocilpine) as an adjuvant therapy in experimental neonal bacterial meningitis. Meningitis was induced by injecting 10(6) colony forming units of Escherichia coli into the cisterna magna. MK-801 3 mg/kg was given as a bolus intravenous injection, 30 min before the induction of meningitis. MK-801 did n...

Folinic acid-responsive seizures (FARS) are a rare treatable cause of neonatal epilepsy. They have characteristic peaks on CSF monoamine metabolite analysis, and have mutations in the ALDH7A1 gene, characteristically found in pyridoxine-dependent epilepsy. There are case reports of patients presenting with seizures at a later age, and with folate deficiency due to different mechanisms with vari...

We have shown that in the osteopetrotic rat mutation toothless (tl) osteoblasts are absent from older bone surfaces in mutants and that mutant osteoblasts in vivo lack the prominent stress fiber bundles polarized along bone surfaces in osteoblasts from normal littermates. Our recent data demonstrate that in normal osteoblasts in vitro beta- and gamma-actin mRNAs have different, characteristic i...
