We report a pediatric patient with chronic idiopathic thrombocytopenic purpura who suffered from an influenza A (H1N1) virus infection. A 13-year-old girl presented with fever, coughing, and generalized petechiae. The influenza A antigen was positive in her pharyngeal aspirate. She was successfully treated with neuraminidase inhibitor oseltamivir phosphate. Her platelet counts progressively increased with oseltamivir phosphate without another blood product or agent. We suggest that oseltamivir phosphate can be used in patients with immune thrombocytopenic purpura who present with influenza virus A infection. We also suggest that oseltamivir phosphate can be effective in patients with immune thrombocytopenic purpura. Large study groups are needed to confirm the relationship between idiopathic thrombocytopenic purpura and neurominidase inhibitors.

Caring for young infants can be stressful. Non-accidental brain or head injury (shaken baby syndrome) is a result of parental stress, and a lack of knowledge of how to respond to a crying infant and the dangers of shaking a child. This article demonstrates the value of international collaboration in projects to prevent child maltreatment. It includes reports of prevention of shaken baby syndrome programmes in Australia, Hungary, Greece, Brazil and Turkey.

Leptin, the obese gene product, is a 16-kDa peptide hormone secreted by adiposities. Systemic administration of exogenous glucocorticoids has been found to increase circulating leptin levels. In this study, we aimed to assess serum leptin in children with atopic dermatitis (AD)-treated with local steroids. Twenty children with AD were included during the 2001-2002 time period. The study was conducted prospectively. Atopy was defined as the presence of at least one aeroallergen-specific immunoglobulin E (IgE) antibody. Serum leptin was determined using a commercially available radioimmunoassay kit with 3.4-8.3% intra-assay and 3.0-6.2% interassay coefficients of variation, and 0.5 ng/ml sensitivity. Fourteen boys and six girls with AD, the mean age of the patients was 3.1 +/- 2.2. Forty-three percentage of the family histories for atopy were positive, 60% of the cases passive smoking histories were positive. In seven patients the aeroallergen-specific IgE were positive. All 20 patients treated clobetasone 17-butirate (0.05%). There was no significant difference in serum leptin between patients (mean +/- s.d.: 4.6 +/- 3.8), and controls (mean +/- s.d.: 6.2 +/- 3.6) (p > 0.05). Local steroid does not influence circulating leptin levels, suggesting that regulation of body weight is unaffected.
