The combination of artemether/lumefantrine is indicated for the treatment of acute uncomplicated Plasmodium falciparum malaria. There have been no clinical trials to assess the efficacy of this medication in patients with renal impairment. While it is unlikely that artemether/lumefantrine would be removed during dialysis, clinical experience regarding drug use in this setting is limited. In this article, the authors report successful treatment of Plasmodium malariae malaria on a patient with end-stage kidney disease undergoing hemodialysis.

Introduction Extensively drug-resistant tuberculosis (XDR-TB) is emerging as a global public health problem. Its treatment is more expensive and difficult, and the outcomes much severe. The identification of risk factors for XDR-TB is of paramount importance to design effective TB control strategies. Objective To review published articles on risk factors for XDR-TB. Methods We identified 249 English articles on PubMed, and 182 were excluded by the abstract. The remaining articles were retrieved for full-text detailed evaluation by authors, and 27 relevant articles were selected for final review. Results Some risk factors were consistently present, mainly previous TB treatment and its length. Other conditions often associated were immigration, alcoholism and HIV coinfection. Pre-XDR-TB points to an increased risk of XDR-TB. Conclusion The information regarding determinants of XDR-TB is relatively weak. However, special emphasis should be given to minimize the risks of TB retreatment to prevent the emergence of highly resistant TB.

Introdução: Os homens que têm sexo com homens, particularmente os infectados pelo vírus da imunodeficiência humana (VIH) têm risco aumentado de cancro anal. Ao contrário da maior parte das doenças oportunistas e/ou definidoras de SIDA, os dados são contraditórios no que diz respeito ao efeito da terapêutica antirretrovírica, não sendo claro o impacto da supressão virológica e reconstituição imunitária na evolução da infecção por vírus do papiloma humano (HPV) e prevenção das neoplasias associadas. Actualmente é já recomendada a vacinação de doentes com infecção por VIH contra o HPV; os programas de rastreio do cancro anal, recomendados por algumas organizações, carecem ainda de validação definitiva da sua eficácia.Material e Métodos: Os autores fizeram um estudo retrospectivo dos casos de cancro anal diagnosticados entre 2000-2015 em doentes com infecção por VIH em seguimento no serviço de Infecciologia do Hospital de Curry Cabral, em Lisboa. São avaliadas as características clínicas e epidemiológicas dos doentes com cancro do canal anal ao longo de um período de quinze anos.Resultados: O cancro anal foi diagnosticado em dez doentes, maioritariamente homens HSH, com infecção por VIH com uma duração média de 15,1 anos, com contagem média de linfócitos TCD4+ de 441 células/uL. O diagnóstico foi mais frequentemente realizado no estádio III e o tratamento mais frequente foi cirúrgico, ocasionalmente conjugado com radioterapia. Faleceram 4 doentes.Conclusões: São necessários programas de rastreio consensuais do cancro anal, a par da necessidade de reforço da vacinação contra o HPV nos homens, nomeadamente nos homens que têm sexo com homens, com ou sem infecção por VIH.

BACKGROUND: Hand, foot, and mouth syndrome (HFMS) is a common acute illness. It is characterized by mild clinical symptoms including fever, blisters, and sores in the mouth and on the palms and soles following a 3- to 7-day incubation period. This syndrome is rarely seen in adults. CASE PRESENTATION: A 35-year-old male Caucasian patient had a history of multiple episodes of acute pharyngitis, hypertension, hypercholesterolemia, and occasional abdominal pain. He presented with polyarthralgia in the knees and hands and odynophagia, followed by fever, oral mucosal aphthous lesions, and vesicles on the palms and soles. Three weeks after presentation, he was admitted to the emergency room with acute myocarditis. The in-hospital evaluation revealed positive serology for coxsackie A9 (1:160), positive anti-transglutaminase and anti-gliadin antibodies, normal immunoglobulins, and human immunodeficiency virus negativity. CONCLUSION: We herein describe a case of HFMS that was associated with coxsackie A9 infection complicated by acute myocarditis. Although an association between celiac disease and HFMS has not been described, this patient's immunologic disruption could have favored the development of infection and ultimately HFMS.
