Molecular epidemiology and antibiotic susceptibility pattern of Acinetobacter baumannii isolated from children in a Turkish university hospital.

The aim of the present study is to investigate the types of healthcare-associated infections (HC-AIs) caused by Acinetobacter baumannii and the related antibiotic susceptibility patterns as well as the genotypic characteristics of the Acinetobacter baumannii isolates from our center. Sixty-nine Acinetobacter baumannii isolates originating from various samples collected from 69 pediatric patients during their hospital stays were included in the study. The types of healthcare-associated infections caused by these isolates were evaluated, and the antibiotic susceptibility pattern and the genotypic characteristics of the isolates were determined using the pulsed-field gel electrophoresis (PFGE) method.

Polymorphisms in NRAMP1 and MBL2 genes and their relations with tuberculosis in Turkish children.

In this study, we aimed to determine genetic susceptibility of children group who are under follow up at outpatient and inpatient clinics or newly diagnosed pediatric tuberculosis according to healthy control group. Patient group consists of 50 cases aged between 0-18 years who are under follow up at outpatient and inpatient clinics or newly diagnosed pediatric tuberculosis between 1996-2009 in Cukurova University, Faculty of Medicine, Department of Pediatrics and the control group consists of 50 healthy cases aged between 0-18 years who have neither chronic nor acute diseases and have no history of tuberculosis contact. Analysis of NRAMP1 (D543N, 3'-UTR and INT4 loci) and MBL (codon 54 and 57) gene polymorphisms carried out in Cukurova University, Faculty of Medicine, Department of Medical Biology and Genetics.

Systemic phaeohyphomycosis due to Exophiala (Wangiella) in an immunocompetent child.

We report a rare case of systemic lymphadenitis and hepatic involvement due to Exophiala (Wangiella) dermatitidis in a pediatric patient. An 8-year-old immunocompetent boy with chronic fever was examined through the use of sonography and CT scan which demonstrated cervical and mesenteric lymph node enlargement and numerous small hepatic lesions. The etiologic agent was isolated by means of lymph node aspiration.

Role of procalcitonin, C-reactive protein, interleukin-6, interleukin-8 and tumor necrosis factor-alpha in the diagnosis of neonatal sepsis.

Diagnosis of neonatal sepsis may be difficult because clinical presentations are often nonspecific, bacterial cultures are time-consuming and other laboratory tests lack sensitivity and specificity. In this study, we aimed to investigate the role of procalcitonin (PCT), C-reactive protein (CRP), interleukin (IL)-6, IL-8 and tumor necrosis factor-alpha (TNF-alpha) in establishing the diagnosis and evaluating the prognosis of neonatal sepsis. Twenty-six neonates with blood-culture positivity and clinical sepsis, hospitalized for clinical suspicion of neonatal sepsis in neonatal intensive care units of Balcali Hospital, Cukurova University and Adana State Hospital between May 2000 and January 2001 (Group I) and 29 healthy neonates followed at the neonatal units and outpatient clinics of these hospitals (Group II) in the same period were studied.

Decline of maternal hepatitis a antibodies during the first 2 years of life in infants born in Turkey.

Selective immunization of at-risk groups may reduce the incidence of hepatitis A infection, but only the inclusion of hepatitis A vaccine in a routine universal childhood immunization schedule would guarantee control of the infection. But the interference by maternally derived hepatitis A antibodies (anti-HAV) with the immunogenicity of inactivated hepatitis A vaccine is still important in the determination of the optimal age for hepatitis A vaccination. The hepatitis A vaccines have not been assessed widely in children under the age of 2 years and are not currently licensed for this age group in many countries.

The value of a new microculture method for diagnosis of visceral leishmaniasis by using bone marrow and peripheral blood.

We have demonstrated that the microculture method (MCM) enables the diagnosis of visceral leishmaniasis (VL) with samples from both the bone marrow (BM) and peripheral blood (PB). The MCM is superior to the traditional culture method (TCM) as determined by its higher sensitivity in the detection of promastigotes and the more rapid time for emergence of promastigotes. The sensitivity of MCM (100% in BMs and 77.

Bacillary angiomatosis in an immunocompetent child with a grafted traumatic wound.

Bacillary angiomatosis is an infectious disease which usually develops in immunocompromised patients. Contact with cats is implicated in its pathogenesis. We report a seven-year-old immunocompetent boy with bacillary angiomatosis without a history of direct contact with cats.
