Pentavalent antimonials are first-line drugs for the treatment of the cutaneous form of American tegumentary leishmaniasis. Second-line drugs include amphotericin B and pentamidine. Although these drugs have been used for decades, there are no systematic reviews about their safety. The objective of this review was to identify and classify the main adverse effects associated with these drugs and to estimate the frequency of these effects, whenever possible. Intervention studies, case series and case reports containing information regarding clinical, laboratory or electrocardiographic adverse effects of drugs used for the treatment of cutaneous leishmaniasis were systematically retrieved from 10 databases searched between August 13, 2008 and March 31, 2009. The 65 studies included in this review had treated a total of 4359 patients from 12 countries infected with eight different Leishmania species. Despite the small number of drugs used in these studies, a wide variability in the therapeutic regimens was observed. As a consequence, the adverse effects of pentavalent antimonials and pentamidine needed to be classified jointly according to system, irrespective of formulation, daily dose, duration of treatment, and route of administration. The frequencies of adverse effects were calculated based on the data of 32 articles involving 1866 patients. The most frequently reported clinical adverse effects of pentavalent antimonials and pentamidine were musculoskeletal pain, gastrointestinal disturbances, and mild to moderate headache. Electrocardiographic QTc interval prolongation and a mild to moderate increase in liver and pancreatic enzymes were additional adverse effects of pentavalent antimonials. Patients treated with liposomal amphotericin B had mild dyspnea and erythema. The adverse effects associated with miltefosine were vomiting, nausea, kinetosis, headache, diarrhea, and a mild to moderate increase in aminotransferases and creatinine. Although closer surveillance is needed for the treatment of cutaneous leishmaniasis, antileishmanial drugs are basically safe and severe side effects requiring the discontinuation of treatment are relatively uncommon.

Chikungunya fever has become an important public health problem in countries where epidemics occur because half of the cases progress to chronic, persistent and debilitating arthritis. Literature data on specific therapies at the various phases of arthropathy caused by chikungunya virus (CHIKV) infection are limited, lacking quality randomized trials assessing the efficacies of different therapies. There are a few studies on the treatment of musculoskeletal manifestations of chikungunya fever, but these studies have important methodological limitations. The data currently available preclude conclusions favorable or contrary to specific therapies, or an adequate comparison between the different drugs used. The objective of this study was to develop recommendations for the treatment of chikungunya fever in Brazil. A literature review was performed via evidence-based selection of articles in the databases Medline, SciELO, PubMed and Embase and conference proceedings abstracts, in addition to expert opinions to support decision-making in defining recommendations. The Delphi method was used to define the degrees of agreement in 2 face-to-face meetings and several online voting rounds. This study is part 2 of the Recommendations of the Brazilian Society of Rheumatology (Sociedade Brasileira de Reumatologia - SBR) for the Diagnosis and Treatment of chikungunya fever and specifically addresses treatment.

Summary:We investigated the use of 'prophylactic' donor lymphocyte infusions (DLI) containing 1 ؋ 10 7 CD3 ؉ cells, given at 30, 60 and 90 days post-allogeneic blood and marrow transplantation (BMT), following conditioning with fludarabine 30 mg/m 2 /4 days and melphalan 70 mg/m 2 /2 days. GVHD prophylaxis consisted of cyclosporin A (CsA) 2 mg/kg daily with early tapering by day 60. Our goals were the rapid achievement of chimerism and disease control, providing an immunological platform for DLIs to treat refractory patients with hematological malignancies. Twelve heavily pre-treated patients with life expectancy less than 6 months were studied; none were in remission. Diagnoses were AML (n ‫؍‬ 4), MDS (n ‫؍‬ 1), ALL (n ‫؍‬ 3), CML (n ‫؍‬ 3) and multiple myeloma (n ‫؍‬ 1). Response rate was 75%. Three patients are alive at a median of 450 days (range, 450-540). Two patients are in remission of CML in blast crisis and AML for more than 14 months. Median survival is 116 days (range, 25-648). Six patients received 12 DLIs; three patients developed acute GVHD after the first infusion and were excluded from further DLIs, but no GVHD occurred among patients receiving subsequent DLIs. One patient with CML in blast crisis went into CR after the first DLI. The overall incidence of acute GVHD was 70%. Primary causes of death were infections (n ‫؍‬ 3), acute GVHD (n ‫؍‬ 3), chronic GVHD (n ‫؍‬ 1) and disease relapse (n ‫؍‬ 2). We observed high response and chimerism rates at the expense of an excessive incidence of GVHD. DLI given at day ؉30 post BMT caused GVHD in 50% of the patients, and its role in this setting remains unclear. The therapeutic benefit of allogeneic BMT is in part related to an immunological graft-versus-leukemia (GVL) effect that frequently evolves in the context of graft-versus-host disease (GVHD). The ability of donor lymphocytes to induce remission in patients relapsing after allogeneic transplantation illustrates the potency of this effect.1 Establishing donor-recipient tolerance with less toxic regimens may provide the basis for further immunological manipulations in order to maximize the GVL effect. However, rapidly evolving diseases may not be amenable to this strategy, considering that the immune-mediated elimination of malignant cells may take weeks or months to occur. This fact suggests the need for strategies to reinforce the immune-mediated phenomena in the post-transplant period.Groups in Jerusalem and Houston pioneered the use of sub-lethal doses of fludarabine-based conditioning regimens. These regimens have been shown to be less toxic and to provide enough immunosuppression to prevent graft rejection and establish stable mixed or complete chimerism.2,3 The combination of melphalan and fludarabine has enabled allogeneic stem cell engraftment in the majority of patients treated, at least in the setting of HLA-identical transplantation. Patients with refractory relapses of advanced leukemias appear to benefit the least.

Chikungunya fever has become a relevant public health problem in countries where epidemics occur. Until 2013, only imported cases occurred in the Americas, but in October of that year, the first cases were reported in Saint Marin island in the Caribbean. The first autochthonous cases were confirmed in Brazil in September 2014; until epidemiological week 37 of 2016, 236,287 probable cases of infection with Chikungunya virus had been registered, 116,523 of which had serological confirmation. Environmental changes caused by humans, disorderly urban growth and an ever-increasing number of international travelers were described as the factors responsible for the emergence of large-scale epidemics. Clinically characterized by fever and joint pain in the acute stage, approximately half of patients progress to the chronic stage (beyond 3 months), which is accompanied by persistent and disabling pain. The aim of the present study was to formulate recommendations for the diagnosis and treatment of Chikungunya fever in Brazil. A literature review was performed in the MEDLINE, SciELO and PubMed databases to ground the decisions for recommendations. The degree of concordance among experts was established through the Delphi method, involving 2 in-person meetings and several online voting rounds. In total, 25 recommendations were formulated and divided into 3 thematic groups: (1) clinical, laboratory and imaging diagnosis; (2) special situations; and (3) treatment. The first 2 themes are presented in part 1, and treatment is presented in part 2.

Highlights WHO and ILO are developing joint estimates of work-related burden of disease and injury. We systematically reviewed effect of occupational exposure to noise on CVD. We found 17 eligible studies with 534,688 participants in 11 countries/3 WHO regions. We are very uncertain about the effect of occupational exposure to noise on CVD.

A osteoporose é uma síndrome multifatorial do esqueleto, sendo a fratura de fêmur a mais séria consequência para idosos, devido à alta mortalidade e ao custo. Este trabalho descreveu as fraturas osteoporóticas de fêmur em idosos para o Brasil, no triênio 2006-2008. A Autorização de Internação Hospitalar (AIH) foi utilizada como base secundária de dados e permitiu criar indicadores para fratura de fêmur em idosos. As proporções de idosos internados no Sistema Único de Saúde (SUS) por esta causa chegaram a 1%. Os percentuais de internação e óbitos foram maiores no sexo feminino e aumentaram com a idade. Os gastos foram de aproximadamente 2% dos gastos do SUS para pessoas com 60 anos ou mais. A maioria das internações durou de um a sete dias; 50,1% ocorreram em hospitais filantrópicos; e 42,7% aconteceram fora do município de residência. Os resultados reforçam a necessidade de maior atenção para a osteoporose e mostram a relevância dos gastos públicos com internações de idosos por fratura osteoporótica de fêmur. A compreensão de tais internações auxilia a formulação de políticas de saúde para esta causa.
