Infections of cerebrospinal fluid shunts continue to be a substantial source of mortality and morbidity in children with hydrocephalus. Although several therapeutic modalities are currently used for the treatment of shunt infections, there are no clear guidelines for treatment. The purpose of this study was to determine the common pathogens of cerebrospinal fluid shunt infections and evaluate the success of our management. Thirty-five children treated for ventriculoperitoneal shunt infections over the past 9 years were reviewed. The management protocol consisted of the removal of the infected shunt, the application of ventricular taps or reservoir placement, intraventricular antibiotic treatment, and the placement of a new shunt when cerebrospinal fluid sterility was achieved. Four patients were treated with antibiotics alone. Most episodes occurred within 4 months of shunt placement. The most common causative microorganism identified was Staphylococcus epidermidis, followed by S. aureus, and S. warneri. Three patients died from complications of shunt infections, 2 patients had a recurrent shunt infection, while the remaining 29 patients remained free from shunt-related complications. In agreement with the evidence published in the literature, our findings suggest that the above management protocol is effective for the treatment of cerebrospinal fluid shunt infections.

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. A prospective trial was performed to detect seroprevalence of maternal hepatitis A antibodies during the first 2 years of life among young infants born to hepatitis A antibody positive mothers in Turkey. We measured at-birth anti-HAV in 147 infants born in our hospital and in their mothers and then from the offspring at months 3, 6, 9, 12, 15, 18, 21, and 24. The prevalence of seropositivity among the mothers at birth were found similarly high (93.9%) to the studies previously done among the adults in our area. The prevalence of anti-HAV among children aged 0, 9, 12, 15, 18, and 21 months were 93.9%, 62.6%, 36.1%, 13.6%, 6.1%, and 0.7%, respectively. Although a proportion of infants still had measurable antibodies at 9 and 12 month of age, two thirds of the infants over the age of 12 months were at high risk of acquiring hepatitis A infection, as living in a endemic region.

We examined 41 Turkish children with haemophilia for evidence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections using the enzyme-linked immunosorbent assay (ELISA). Hepatitis B surface antigen was found to be positive in 11 patients (26.8%) and HCV-specific antibody (anti-HCV) was detected in 10 (24.4%) patients. There was a close relationship of the number of transfusions of blood plasma to the presence of HCV specific antibody, but not to the serum markers of HBV infection. In countries where HBV infection is commonly seen and problems in transfusion practice continue, as in Turkey, children with haemophilia are at greater risk for HBV and HCV infections.

Between May 1988 and November 1992 the data from 52 patients with tuberculous meningitis (TBM) were noted down for their symptoms and signs, BCG vaccines, PPD tests; clinical, laboratory, radiologic and microbiologic findings. These data were discussed by means of literature knowledge. Cranial computed tomography (CT) demonstrated hydrocephalus (HC) in 98% of the patients. There was a statistically significant difference among the clinical stages on admission in respect to prognosis (P < 0.05). In addition, there was also a significant relationship between prognosis and HC (P < 0.05). However, we did not find any significant relationship between parenchymal involvement, basilar meningitis and prognosis (P > 0.05).

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. The clinical diagnosis of bacillary angiomatosis was made following histopathological examination of a biopsy sample from the infected facial wound, in the vicinity of which angiomatous lesions had developed. Surprisingly, similar lesions also appeared at the donor site of the skin graft which was grafted on the facial wound. This case demonstrates that bacillary angiomatosis may also be seen in immunocompetent patients and that it may contaminate wounds without the intermediary of cats.
