Abstract
Background: Bacterial meningitis is one of the most serious infections in infants and children. Three organisms include S.PneumoN.meningH.Influ are the most common cause of meningitis in children between 2M-14y age.Etest is a new method for determination the MIC of some antimicrobial drugs in agarose .This method is useful for some organisms like as S .Pneumo N.mening H.Influsensitive Streptococcus and anaerobic aerobic gram negative.
Materials and Methods: In this descriptive cross sectional study In 57 suspected meningitis children organisms isolated from blood CSF or other sterile boy fluid after culturing and antibiogram. .MIC of someorganisms detected by Etest method.

Conclusion: Most type of N.meningitidisH.inf and S.pneumonia were sensitive to many drugs. Only minority of them were resistant to Ampicillin but sensitive to chloramphenicol and vice versa. limited number of pneumococcal resistance to penicillin is medium resistance( MIC:0.1-1) .we can treat this resistant type by increasing of penicillin dosage .The others were sensitive to all drugs. Therefore ampicillin and chloramphenicol are the drug of choice in empiric treatment of bacterial meningitis after neonatal period.

Abstract
Background: Acute respiratory tract infections, both bacterial and viral, cause 4.5 million childhood deaths worldwide, most of which occur in developing countries. Parainfluenza viruses, of the paramyxoviridae family, are among the common causes of acute respiratory infections, giving rise to 30% of respiratory infections in children before school age. The four parainfluenza viruses that cause a spectrum of respiratory illness in humans are designated as human para influenza virus-1 through 4. Spreading from the respiratory tract by aerosolized secretions or direct hand contact with secretions, parainfluenza viruses replicate in the respiratory epithelium without evidence of systemic spread. The destruction of cells in the upper airways can lead to secondary bacterial invasion and resultant bacterial tracheitis. Eustachian tube obstruction can lead to secondary bacterial invasion of the middle ear space and acute otitis media. In otherwise healthy children, the majority of illnesses remain in the upper respiratory tract. As with many viruses, three approaches to the diagnosis of parainfluenza virus are currently used: viral culture, detection of viral antigen or nucleic acid, and serologic analysis. The gold standard remains the isolation of virus in tissue culture.
Methods: This descriptive case-series study was conducted from January 2003 to January 2004, and included 96 children five years of age and younger. To determine the relative frequency of parainfluenza respiratory tract infection, the nasopharyngeal secretions were studied by immunofluorescent antibody (IFA) assay. Seasonal incidence, age distribution and clinical signs and symptoms of this infection were also recorded.
Results: Among our study group, the relative frequency of parainfluenza respiratory infection was 26%, most commonly in children aged 25-36 months and in autumn. Cough (84%) and rhinorrhea (96%) were the most common symptoms, with fever (68%) as the most common sign in our patients. Pharyngotonsilitis was the most common (40%) clinical manifestation in our patients.
Conclusions: According to above data, patient age and the frequency of parainfluenza infection were similar to other studies.

Abstract
Background: There are many methods for removal of tracheobronchial foreign bodies
but there are many situations where removal of a foreign body seems impossible and
may require a major surgical procedure. Familiarity with each method improves
physician decision making.
Case: A 17 months old baby with a history of foreign body aspiration suffered from long
term pneumonia. There was a round shape foreign body in bronchoscopic view that
could not be removed with standard methods, but was removed by application of Fogarty
catheter
Conclusion: Removal of round, spherical foreign bodies may be performed by Fogarty
Catheter preventing surgical intervention.

Abstract
Background: Early diagnosis of bacteremia and its complications is the most important part of care and management of the patients. The utility of polymerase chain reaction (PCR) techniques have been shown to identify pathogens in less and more optimal time. The aim of our study was to evaluate prevalence of bacteremia using universal PCR in febrile patients admitted in Pediatric Medical Center comparing other routine methods like blood culture.
Methods: One hundred febrile children suspected to septicemia who were admitted in Pediatric Medical Center, were included. From all patients whole blood samples were obtained for blood culture and PCR.
Results: Of all patients, 65% were 3 to 36 months old. The frequency of male and female patients was 45 and 55, respectively. The prior oral and parental antibiotic therapy had been taken for 45 and 12 patients. The mean temperature of body was 38.98±0.57 at presenting time. Twelve patients were positive blood culture. Nineteen patients had positive PCR test which consisted of 11 patients with positive blood culture. The severity of fever and laboratory findings such as WBC, ESR, and CRP had no significant difference between patients with positive and negative blood culture and PCR.
Conclusion: universal PCR technique is more sensitive and specific than conventional blood culture and other methods to diagnose bacterial infection.

Background: Latent Epstein- Barr
virus (EBV) genomes are found in the malignant cells of
approximately one-third of Hodgkin's lymphoma (HL) cases. Detection of EBV viral DNA could potentially be used as a biomarker of disease activity. Our goal was
to compare of EBV DNA detection in samples obtained from lymphoma
patients versus controls.
Methods: One milliliter uncoagulated and 1ml coagulated blood sample for DNA extraction and serum analysis using ELISA for IgG anti EBNA-1 were obtained from 44 lymphoma patients and from 44 normal controls,
respectively. EBV genome, EBNA-2, was examined from DNA extracts of paraffin
embedded and blood samples using Nested PCR with type specific inner primers.
Results: Positive results for ELISA, Blood and biopsy PCR in study group were, 84.1%, 27.3% and 13.6%, respectively. However, these results in
control group were 47.7% and 16% for ELISA and Blood PCR assays, respectively. Positive results in ELISA, Blood PCR and Biopsy PCR in Hodgkin and non-Hodgkin patients were found in 21(84%), 6(24%), 4(16%) and 16(84.2%), 6(31.6%), 2(10.5%) of specimens, respectively. No significant
differences in EBV detection were found between these two
patient groups (p values for ELISA, Blood PCR and Biopsy PCR were 0.26, 0.73 and 0.68, respectively).
Conclusion: Comparison of ELISA and Blood PCR results in children and adult
patients with the same age of controls have showed difference in ELISA results of children, only.
None of the test results have showed statistically significant difference
between Hodgkin and non-Hodgkin patients. However, the mean of ELISA results in Hodgkin patients
was higher as compared with controls. Blood PCR assay cannot be recommended as a biomarker of disease activity in EBV positive Hodgkin's lymphoma
patients.

Abstract
Background: Human respiratory syncytial virus (HRSV) is the most important viral agent of acute lower respiratory tract disease in infants and young children worldwide. This virus is responsible for 50% brochiolitis and 25% pneumonia in infants. There are limited data of molecular epidemiology of HRSV from developing countries. This is the report on the molecular epidemiology of human respiratory syncytial virus in Iran. Methods: In this study, RT-PCR for second hypervariable region of the HRSV G glycoprotein was performed on 72 throat swabs collected from children less than 5 years of age with acute respiratory symptoms in 1386.
Results: Of the 72 throat swabs collected from children with acute respiratory symptoms, 14 (19.44%) were positive for HRSV. Phylogenetic analysis revealed that all HRSV-positive samples clustered in three genotypes of subgroup A: 12 strains (85/71%) in genotype GA2, 1 strain (7/1%) in genotype GA1, and 1 strain (7/1%) in genotype GA5. In this study we couldn’t identify any genotype of subgroup B.
Conclusion: Our results revealed that multiple genotypes of subgroup A were co- circulated during 1386 in children less than 5 years of age in Iran. Also this study revealed that genotype GA2 was predominant genotype in isolates were obtained from several cities (Tehran, Isfahan, Karaj, Qazvin, Bandar Abbas, Shahreza), so we speculate that this genotype may be predominant during 1386 in Iran. This study supported that RT-PCR for second variable region of G protein is an effective method for further studies of HRSV genotype designation in Iran.
