Case Reports
Surveillance of the first case of human avian influenza A (H7N9) virus in Beijing, China.
Human infections with avian influenza A (H7N9) virus manifested in China in March 2013. The first case infected with H7N9 virus in Beijing involved a family member of a chicken dealer and was reported in April 2013. The clinical and epidemiological characteristics of this case and her parents were examined to illustrate some key traits regarding this novel H7N9 virus. ⋯ Early diagnosis and early initiation of the treatment of confirmed infections is the most effective strategy for managing H7N9 virus infection. Human beings exposed to H7N9 virus may develop asymptomatic infection.

Colistin is increasingly used as the last-resort treatment option against infections caused by multidrug-resistant (MDR) Gram-negative pathogens, but its nephrotoxicity is of concern, especially in severely ill patients. The aim of this study was to analyze the toxicity of colistin therapy in adults and children with hematological malignancies (HM) and hematopoietic stem cell transplantation (HSCT) recipients. ⋯ Treatment with intravenous colistin, with dosage adjusted to renal function, was relatively safe for HM/HSCT patients, even with concomitantly administered nephrotoxic medications. Concern about nephrotoxicity should not justify a delay in initiating empirical colistin treatment in situations where infection with MDR Gram-negative rods is likely.

Practice Guideline
Therapy and prophylaxis of opportunistic infections in HIV-infected patients: a guideline by the German and Austrian AIDS societies (DAIG/ÖAG) (AWMF 055/066).
There was a growing need for practical guidelines for the most common OIs in Germany and Austria under consideration of the local epidemiological conditions. ⋯ The review presented here is a translation of a short version of the German-Austrian Guidelines of opportunistic infections in HIV patients. These guidelines are well-accepted in a clinical setting in both Germany and Austria. They lead to a similar treatment of a heterogeneous group of patients in these countries.

Interferon-gamma release assays (IGRAs) have high specificity and sensitivity for the diagnosis of tuberculosis (TB) infection. However, their role as a screening tool in children with immunodeficiency disorders is still unclear. In the present study, we performed a contact investigation using serial IGRAs on children with immunodeficiency conditions exposed to a contagious TB patient. ⋯ T-SPOT provided more determinate results and was less influenced by low age and lymphocytopenia than QFT-GIT in this population of immunodeficient children. These findings suggest that T-SPOT is a more accurate test for the identification of TB infection in young children with lymphocytopenia and should be preferred to QFT-GIT under such specific conditions.
