Chikungunya: bending over the Americas and the rest of the world

Abstract Chikungunya is an arthropod-borne virus transmitted by Aedes mosquito bites. A viral mutation has allowed Aedes albopictus to become the preferred vector extending the geographic spread of the condition. The virus causes an acute febrile illness occasionally followed by a chronic rheumatic condition causing severe impairment. The diagnosis is usually confirmed with serology. No specific treatment is currently available. This article reviews the condition with emphasis on his dissemination in the Americas.

Vascular access-related infections in HIV patients undergoing hemodialysis: case description and literature review

Poor immune status, the use of a vascular access different from an AV fistula, and intravenous drug use (IDU) may favor increased rates of vascular access infections among HIV infected patients on hemodialysis. Staphylococcus spp. and Streptococcus spp. are the main cause of these infections, but Gram-negative rods and fungi have been found as well. Using an AV fistula when possible, and eliciting a history of IVDU on every visit may prevent this type of infection. When infections are present, coverage for both Gram-positive and negative organisms is recommended. Additional studies specifically addressing the issue of vascular access infection in HIV infected patients are required.
