| Although several invasive and noninvasive tests have been developed for the diagnosis of Helicobacter pylori infection, all of the tests have their limitations. We conducted a study to investigate and compare the suitability of rapid urease test (RUT), serology, histopathology and stool antigen tests with polymerase chain reaction (PCR) for detection of H. pylori, and correlate the diagnostic methods with PCR. Eighty nine patients (61 adults, 28 children) referred to the Firoozgar Hospital and Children Medical Center Hospital for diagnostic upper gastrointestinal endoscopy entered to the study and noninvasive tests such as immunoassay for serological antibodies against H. pylori and detection of its antigen in feces were measured. The biopsies were... |

| BACKGROUND: Fever as a common presenting complaint in pediatric patients can be due to various causes. Differentiating bacterial infection from other causes is important because the prompt use of antibiotics is critical in bacterial infection. Traditional markers of infection such as BT and WBC count may be unspecific and culture may be late or absent. CRP and Procalcitonin (PCT) have been considered to evaluate the evolution of infections and sepsis in patients presenting with SIRS. Neopterin has also been proposed to aid in the diagnosis of bacterial infection. In this study, we compared the value of the serum PCT, neopterin level, and WBC count for predicting bacterial infection and outcome in children with fever. METHODS: 158 pediatric... |

| Appropriate antimicrobial treatment of shigellosis depends on identifying its changing resistance pattern over time. We evaluated 15,255 stool culture submitted from July 2001 to June 2006 to the Laboratory of Children Medical Center Hospital. Specimen culture, bacterial identification, and disk diffusion susceptibility testing were performed according to National Committee for Clinical Laboratory Standards guidelines. From 15,255 stool samples, 682 (4.5%) were positive for Shigella species. The most common species of Shigella were S. flexneri (48%) and S. sonnei (45%); other results were S. dysenteriae (5%) and S. boydii (2%). The rate of Sensitivity to ceftriaxone (95%), ceftizoxime (94%), and nalidixic acid (84%) were among our isolates. Resistance to... |

| Emerging antimicrobial resistance rates and Extended-spectrum beta-lactamase producing Escherichia coli recovered from urinary tract infections (UTI) is an increasing problem in specific regions, limiting therapeutic options. One hundred E. coli isolates causing UTI in patients with age from 2 months to 12 years admitted at CMC in the period of April 2009 to March 2010 were tested for antibiotic susceptibility using the disk diffusion method. Surprisingly high resistance rates were recorded for E. coli against TMP/SMX (84%), cefalotin (66%), cefuroxime (50%), cefixime (50%) and ceftriaxone (45%). Antimicrobial susceptibility of E. coli isolates was followed by meropenem (98%), amikacin (95%), nitrofurantoin (91%) and gentamicin (68%). Extended spectrum... |
