[Evaluation of epidemiological, clinical and laboratory findings of admitted patients with meningitis in infectious diseases ward of Razi hospital, Ahvaz]

Familiarity with the epidemiological, clinical and laboratory features of bacterial meningitis [BM] is important for rapid diagnosis and initiation of antibacterial therapy. This study aimed at evaluating these patients based on their epidemiological, clinical and laboratory findings and comparing these variables with patients with aseptic meningitis [ASM]. Admitted patients aged 18 years or more who were hospitalized because of meningitis, were studied between 2003 and 2007. Cases were grouped as BM and ASM and compared for their epidemiological, clinical and cerebrospinal fluid [CSF] laboratory aspects. Among 312 patients with meningitis, 215 [68.9%] had BM [42 definite, 156 probable and 17 partially treated] and 97 [31.1.%] had ASM. The mean age of patients with BM was 44.7 +/- 26.7 years and for ASM was 37.3 +/- 15.5 years [P>0.05]. Twelve percent of cases had triad of fever, neck stiffness and low level of consciousness. The means for CSF-WBC, CSF- glucose and CSF-protein in BM compared with ASM patients were 4021.6 +/- 1035.2 and 163.2 +/- 116.4 cell/microl of CSF; 27.5 +/- 17.3 and 68.7 +/- 16.lmg/dl and 689.8 +/- 476.8 and 132.6 +/- 107.7mg/dl, respectively [P<0.05]. The prevalence of BM was higher than that of ASM. Tuberculous meningitis had a considerable frequency among ASM patients. Confirmed BM based on CSF culture was lower than other studies. The number of performed LP procedures was not in accordance with the total meningitis cases. Similarly, WBC and glucose in CSF were helpful in differential diagnosis of BM vs. ASM

[Seroprevalence of legionella pneumophila in patients with, community acquired pneumonia]

Legionella pneumophila [LP] is a major cause of pneumonia worldwide. In spite of suitable epidemiological conditions and probability of LP existence in the region, the incidence of LP infection has not been determined in Ahvaz. Determination the seroprevalence of LP in patients with Community Acquired Pneumonia [CAP]. In this prospective descriptive study, during one year period [2007-2008], 80 admitted patients were selected in Razi Hospital of Jundi Shapoor University of Medical Science in Ahvaz with CAP and was studied the serprevalence of LP among them. Sera were tested for L. pneumophila IgG and IgM by using Elisa kit [Vircell, Spain]. Data were analyzed by using SPSS, version 16 statistical package. Among 80 serum samples, 12 cases [15%] were positive for LP- IgG+ IgM. Age, gender and area of residency did not significantly affect the seroprevalence of L P. [P>0.05]. The prevalence of L P seropositivity was not significantly affected by co-morbidities except diabetes mellitus [P>0.05]. Smoking and receiving antibiotic was observed in 100% seropositive patients. Legionella Pneumophila is a prevalent infectious agent in Ahvaz and should be considered in patients with CAP especially in diabetic and smoker patients
