treatment of hydrocephalus in posterior fossa tumors in children is still a matter of controversy and different centers have their own routines. in this regard, hospital records of all children with posterior fossa tumors treated in our center during the interval of 1985-1995 were reviewed. patients’ demographic and diagnostic data were analyzed and the frequencies of shunting procedures were d...

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...

mumps infection is endemic in iran. our objective was to evaluate the presence of anti mumps antibodies ( igm & igg) in cerebrospinal fluid in mumps meningoencephalitic children. a prospective/cross-sectional study was performed in tehran, iran (2003 to 2004) and serum anti mumps antibodies (igm) were detected (quantitive; elisa) in meningoencephaltis patients. specific anti mumps antibodies (i...

objective cerebrospinal fluid (csf), its secretion, circulation and absorption have been the subject of recent researches. there is a general agreement that the main site of csf secretion is in the choroids plexus. however, the main absorption site is controversial. some believe that arachnoid granulations are the principle sites of csf absorption. in this study, different locations of csf abso...

Background & Aims: Neisseria meningitidis is bacteria fastidious, and the main causes of meningitis and acute sepsis. Appropriate treatment depends on accurate and timely diagnosis. This study aimed to identify Neisseria meningitidis infection in samples of cerebrospinal fluid (CSF) in patients with suspected meningitis. Methods: In this study, 198 samples of cerebrospinal fluid of patients wit...

in this review the role of cerebrospinal fluid (csf) in mammalian cerebral cortex development has been highlighted. many studies have focused on the potential role of the csf in the developmental process. in particular, the cerebral cortex develops from the germinal epithelium adjacent to the csf. csf contains proteins, growth factors and other neurotrophic factors which are important for neura...

we describe the development of enterovirus meningoencephalitis associated with increased adenosine deaminase in cerebrospinal fluid of a 12-year-old boy, a known case of hypogamaglobulinemia despite monthly replacement of ivig. the patient was referred to our center with fever, headache and vomiting for 10 days. csf analysis was compatible with aseptic meningoencephalitis but high csf protein (...

background: proposing a strategy for sellar reconstruction in endoscopic transsphenoidal transsellar approach for pituitary adenoma. methods: 240 patients with pituitary adenoma underwent pure endoscopic endonasal transsphenoidal surgery. intra-operative csf leaks were classified as grade 0, no observable leak grade 1, csf dripping through an arachnoid membrane defect of less than 1 mm and grad...

results the mean levels of serum calcium, serum zinc, cerebrospinal fluid calcium and cerebrospinal fluid zinc were 14.51 ± 3.69 mg/dl; 184.04 ± 65.49 µg/dl; 5.23 ± 2.21 mg/dl and 87.06 ± 28.25 µg/dl respectively. conclusions we did not find any clear abnormality in plasma or cerebrospinal fluid calcium and zinc levels in children with febrile seizures in our patient population. patients and me...

meningitis is one of the most important causes of infant mortality and its early and proper diagnosis is of great importance, but there are currently no laboratory facilities optimized and fast in detection of meningitis pathogens. the current standard of bacterial meningitis diagnosis is microscopic examination and cerebrospinal fluid (csf) culture. this research aimed at isolating the most co...
