Interventions to treat methicillin-susceptible Staphylococcus aureus bacteremia: many methodological concerns.

The aim of this letter was to point out some methodological concerns about an article written by Shi et al. and published in the journal. There is an increasing trend in the isolation of Methicillin-susceptible Staphylococcus aureus bacteremia and a variety of questions regarding the best therapy to treat this condition. These concerns might lead to selection, publication and information bias that prevent the generalization and application of these results in our clinical practice.

[Urban outbreak of leishmaniasis in Colombia]. / Brote urbano de leishmaniasis en Colombia.

OBJECTIVES: To describe the epidemiology, clinical characteristics and treatment of children with visceral Leishmaniasis in Neiva- Huila, from April to June 2012. METHODOLOGY: We performed a descriptive study of an outbreak of visceral leshmaniasis in children from the urban area of Neiva. RESULTS: There were seven cases in children younger than five years. All of them had prolonged fever, hepato-splenomegaly, severe anemia and leukopenia. Five were admitted with severe thrombocytopenia, without hemorrhagic manifestations. Six patients received first-line treatment with miltefosine, five of them had treatment failure requirirng therapy escalation to amphotericin B, two received liposomal amphotericin B and three deoxycholate amphotericin B. The main vector identified was the Lutzomyia gomezi and its main reservoir were canines. CONCLUSION: We describe the first visceral leishmaniasis outbreak in children living in an urban area, with no mortality. Most of the cases had a good response to amphotericin B.
