RESUMO

Monkeypox, a neglected disease previously confined to Africa, is causing a worldwide outbreak affecting predominantly males who have sex with males, especially those who are infected with HIV. The clinical presentation during the current outbreak differs from endemic cases. Treatment with tecovirimat and other antivirals is available. Immunization may be used as preexposure and postexposure prophylaxis.

RESUMO

COVID-19 infections have spread widely in Peru, causing severe societal and health impact. We describe the evolution of the epidemics, the reasons for high transmission and the way the disease is diagnosed and managed in the Andean country.

RESUMO

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.

RESUMO

Human bartonellosis is a South American anthroponosis caused by Bartonella bacilliformis. The disease has an acute phase characterized by invasion of red blood cells by parasites, and consequent severe anemia; and a chronic phase presenting with benign vascular tumors. During the acute phase, affected individuals are prone to developing opportunistic infections with a variety of organisms similar to the ones seen in AIDS. After antibiotic treatment is instituted, a subgroup of patients may develop atypical symptoms which potentially represent clinical manifestations of the restoration of macrophage function. We speculate that the pathophysiology of the acute phase of human bartonellosis resembles AIDS, with a period of immunosuppression following the infection and later, clinical manifestations of immune reconstitution subsequent to treatment.

RESUMO

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.
