Description of the dermatoscopic features observed in sporotrichosis and American cutaneous leishmaniasis in a reference center in Rio de Janeiro, Brazil

Abstract Background The evaluation of American cutaneous leishmaniasis (CL) and sporotrichosis (SP) with dermoscopy may improve the diagnosis accuracy and clinical monitoring. Objectives To describe the dermoscopic findings and patterns of skin lesions of patients with CL and SP followed up at the Laboratory of Clinical Research and Surveillance in Leishmaniasis (LaPClinVigiLeish), Evandro Chagas National Institute of Infectious Diseases (INI), Oswaldo Cruz Foundation, Rio de Janeiro, Brazil. Methods The authors included patients with a diagnosis of CL or SP, who attended at INI/ Fiocruz, between 2019‒2021. All patients had 3 dermoscopic examinations (DermLite DL4): before treatment (T0), during treatment (T1), and after healing (T2). Up to three lesions per patient were evaluated. Results The authors studied 47 patients with CL (74 lesions), and 19 patients with SP (24 lesions). The authors described dermoscopic structures such as rosettes, white lines, white dots, brown focal structureless areas, brown lines and dots, white perilesional circles, perilesional hyperchromic circles, microulcerations and the rainbow patterns. The authors created specific patterns; in CL: CL-T0 "central yellow scales with a white perilesional circle pattern", CL-T1 "diffuse structureless white area pattern" and CL-T2 "white and brown focal structureless areas pattern". In SP: SP-T0 the "pustule with erythema pattern"; SP-T1 the "focal structureless white areas with erythema pattern" and SP-T2 the "white linear pattern". Study limitations This study does not correlate dermoscopic findings with time of disease evolution at the first medical examination. Conclusions The recognition of CL and SP dermoscopy patterns may be helpful tool for the differential diagnosis and monitoring of disease evolution.

First report of Leishmania RNA virus 1 in Leishmania (Viannia) braziliensis clinical isolates from Rio de Janeiro State - Brazil

BACKGROUND Leishmania parasites carry a double-stranded RNA virus (Leishmania RNA virus - LRV) that has been divided in LRV1 and LRV2. OBJECTIVES Leishmania (Viannia) braziliensis clinical isolates were assessed in order to determine LRV presence. METHODS Two-round polymerase chain reaction (PCR and nested PCR) was performed to detect LRV1 or LRV2 in L. (V.) braziliensis clinical isolates (n = 12). FINDINGS LRV1 was detected in three clinical isolates which was phylogenetically related to other sequences reported from other American tegumentary leishmaniasis (ATL) endemic areas of Brazil. Patients infected with L. (V.) braziliensis LRV-negative showed only cutaneous lesions while LRV-positive reported different manifestations. MAIN CONCLUSION Data presented here show for the first time that LRV1 is circulating in L. (V.) braziliensis clinical isolates from Rio de Janeiro State in Brazil.

Favorable responses to treatment with 5 mg Sbv/kg/day meglumine antimoniate in patients with American tegumentary leishmaniasis acquired in different Brazilian regions

Abstract INTRODUCTION: Favorable responses in American tegumentary leishmaniasis (ATL) patients to treatment with 5 mg Sbv/kg/day meglumine antimoniate (MA) has been reported in Rio de Janeiro, but little is known regarding the therapeutic response to low doses in patients from other locations. METHODS: A retrospective review of medical records was conducted to compare the therapeutic response to 5 mg Sbv/kg/day MA treatment among 36 patients who acquired ATL in Brazilian states other than Rio de Janeiro (OS group) and 72 patients from Rio de Janeiro (RJ group). RESULTS: One course of 5 mg Sbv/kg/day MA cured 72.8% of 81 cutaneous (CL) and 66.6% of 27 mucosal (ML) leishmaniasis-infected patients: 70% in the CL/RJ group, 81% in the CL/OS group, 50% in the ML/RJ group, and 80% in the ML/OS group. After up to two additional treatment courses at the same dose, 88.9% and 85.2% of the CL and ML patients were cured, respectively. Adverse events were observed in 40% of patients in the CL/RJ group, 57% of the CL/OS group, 58% of the ML/RJ group, and 80% of the ML/OS group. No significant differences were observed in the cure rates or adverse effects between the RJ and OS groups. No patients required permanent discontinuation of treatment due to adverse events. CONCLUSIONS: Patients with ATL acquired in both RJ and OS may respond to low-dose MA. While high-dose MA should remain the standard treatment for ATL, low-dose MA might be preferred when toxicity is a primary concern.

Low dose systemic or intralesional meglumine antimoniate treatment for American tegumentary leishmaniasis results in low lethality, low incidence of relapse, and low late mucosal involvement in a referral centre in Rio de Janeiro, Brazil (2001-2013)

BACKGROUND American tegumentary leishmaniasis (ATL) is a non-lethal parasitic disease that presents with cutaneous (CL) and mucosal (ML) clinical forms. ATL treatment aims at healing the lesions and preventing the development of the late mucosal form. Systemic meglumine antimoniate (MA) therapy with 10-20 mg Sb5+/kg/day is the first choice of treatment. However, alternative therapies using 5 mg Sb5+/kg/day or intralesional (IL) MA are the usual regimens at the National Institute of Infectious Diseases (NIID), Rio de Janeiro, Brazil. OBJECTIVES To evaluate lethality and the incidence of relapse and development of late ML in CL patients treated at NIID from 2001 until 2013. METHODS Data were recovered from records of all ATL patients diagnosed during that period. FINDINGS Out of 777 patients, 753 were treated with MA (96.9%). Of those, 89.1% received alternative therapy of 9.9% IL and 79.2% systemic 5 mg Sb5+/kg/day. Some patients required 1-3 additional courses of treatment, thus making a total of 997 courses; 85.2% of them were subjected to alternative therapies. Lethality was 0.1%, relapse incidence 5.8%, and late ML incidence 0.25%. As a final outcome for the 777 patients, 95.9% were cured, 0.1% died and 4.0% were not able to follow-up. MAIN CONCLUSIONS Alternative MA schedules resulted in low lethality without increase of relapse or late ML incidence.

Effect of secondary infection on epithelialisation and total healing of cutaneous leishmaniasis lesions

BACKGROUND Cutaneous leishmaniasis (CL) generally presents with a single or several localised cutaneous ulcers without involvement of mucous membranes. Ulcerated lesions are susceptible to secondary contamination that may slow the healing process. OBJECTIVE This study verified the influence of non-parasitic wound infection on wound closure (epithelialisation) and total healing. METHODS Twenty-five patients with a confirmed diagnosis of CL and ulcerated lesions underwent biopsy of ulcer borders. One direct microbial parameter (germ identification in cultures) and four indirect clinical parameters (secretion, pain, burning sensation, pruritus) were analysed. FINDINGS Biopsies of ten lesions showed secondary infection by one or two microorganisms (Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, Streptococcus pyogenes and Candida parapsilosis). "Secretion" and "burning sensation" influenced epithelialisation time but not total healing time. Positive detection of germs in the ulcer border and "pain" and "pruritus" revealed no influence on wound closure. CONCLUSIONS Our borderline proof of clinical CL ulcer infection inhibiting CL wound healing supports the need to follow antimicrobial stewardship in CL ulcer management, which was recently proposed for all chronic wounds.

Estigmatização social pela leishmaniose cutânea no estado do Rio de Janeiro, Brasil / Social stigmatization of cutaneous leishmaniasis in the state of Rio de Janeiro, Brazil / Estigmatización social de la leishmaniasis cutánea en el estado del Río de Janeiro, Brasil

Embora a leishmaniose cutânea raramente evolua para óbito, produz um impacto negativo na vida cotidiana, com consequências psicológicas e sociais que afetam as relações pessoais e a qualidade de vida do indivíduo afetado. O objetivo deste estudo foi demonstrar efeitos de comportamentos estigmatizantes, suas consequências psicossociais e sua possível relação com as ideias de cura, contágio e causalidade, a partir do relato verbal dos indivíduos com lesões cutâneas ativas de leishmaniose. Foram entrevistados 24 pacientes com lesões em áreas expostas da pele: quinze do gênero masculino e nove do feminino. Os depoimentos e questões abordadas no estudo mostram um importante impacto psicológico e social, especialmente no gênero feminino, com manifestações de exclusão social e atitudes estigmatizantes. As ideias preconcebidas popularmente sobre a causalidade e o contágio da doença parecem ser responsáveis por essas consequências. Portanto, fazem-se necessários estudos que incorporem uma abordagem multidisciplinar e contextualizada à história sociocultural das populações para minimizar o impacto negativo na vida dos indivíduos afetados. (AU)

Although cutaneous leishmaniasis rarely evolves to death, it has a negative impact on daily life, with psychological and social consequences that interfere with the personal relationships and with the quality of life of the affectedindividual. The objective of this study was to analyze the verbal report of individuals with active cutaneous leishmaniasislesions in order to identify the psychosocial consequences and to demonstrate effects of stigmatizing behaviors and their possible relation with the ideas of cure, contagion and causality. We interviewed 24 patients with active lesions on exposed areas of the skin: fifteen of the male and nine of the female gender. The statements and issues addressed in the study show an important psychological and social impact, especially regarding the female gender, with manifestations of social exclusion and stigmatizing attitudes. Popularly preconceived ideasabout causality and disease contagion seem to be responsible for these consequences. Therefore, there is a needfor studies that incorporate a multidisciplinary and contextualized approach to the sociocultural history of populationsin order to minimize the negative impact on the lives of the affected individuals.

Aunque la leishmaniasis cutánea raramente evoluciona hacia la muerte, produce un impacto negativo en la vidacotidiana, con consecuencias psicológicas y sociales que afectan a las relaciones personales y la calidad de vida del individuo afectado. El objetivo fundamental de este estudio, fue demostrar los efectos de los comportamientos estigmatizantes, sus consecuencias psicosociales y su posible relación con las ideas de cura, contagio y causalidad, a partir de los relatos de los individuos con lesiones cutáneas activas de leishmaniasis. Fueron entrevistados 24pacientes con lesiones en áreas expuestas de la piel: quince hombres y nueve mujeres. Las declaraciones y temas abordados en el estudio muestran un importante impacto psicológico y social, especialmente en el género femenino, con manifestaciones de exclusión social y actitudes de estigmatización. Las ideas preconcebidas popularmentesobre la causalidad y el contagio de la enfermedad parecen ser responsable de esas consecuencias. Por lo tanto, sonnecesarios estudios que incorporen un enfoque multidisciplinario y contextualizado a la historia socio-cultural de las poblaciones, para minimizar el impacto negativo en la vida de las personas afectadas.

Intralesional treatment with meglumine antimoniate in three patients with New World cutaneous leishmaniasis and large periarticular lesions with comorbidities

Abstract Although New World cutaneous leishmaniasis is not itself a life-threatening disease, its treatment with systemic antimonials can cause toxicity that can be dangerous to some patients. Intralesional meglumine antimoniate provides a viable, less toxic alternative. Herein, we describe an alternative treatment with subcutaneous intralesional injections of meglumine antimoniate into large periarticular lesions of three patients with cutaneous leishmaniasis and comorbidities. This treatment was safe, successful, and well tolerated. This case series suggests that intralesional meglumine antimoniate is an effective therapy for cutaneous leishmaniasis, even with periarticular lesions. This hypothesis should be tested in controlled clinical trials.

Sporotrichoid leishmaniasis: a cross-sectional clinical, epidemiological and laboratory study in Rio de Janeiro State, Brazil

ABSTRACT Background Atypical presentations of cutaneous leishmaniasis include sporotrichoid leishmaniasis (SL), which is clinically described as a primary ulcer combined with lymphangitis and nodules and/or ulcerated lesions along its pathway. Aims To assess the differences between patients with sporotrichoid leishmaniasis and typical cutaneous leishmaniasis (CL). Methods From January 2004 to December 2010, 23 cases of SL (4.7%) were detected among 494 CL patients diagnosed at a reference center for the disease in Rio de Janeiro State, Brazil. These 23 cases were compared with the remaining 471 patients presenting CL. Results SL predominated in female patients (60.9%, p = 0.024), with older age (p = 0.032) and with lesions in upper limbs (52.2%, p = 0.028). CL affected more men (64.5%), at younger age, and with a higher number of lesions exclusively in lower limbs (34.8%). Conclusions Differences in clinical and epidemiological presentation were found between SL patients as compared to CL ones, in a region with a known predominance of Leishmania (Viannia) braziliensis. The results are similar to the features of most of the sporotrichosis patients as described in literature, making the differential diagnosis between ATL and sporotrichosis more important in overlapping areas for both diseases, like in Rio de Janeiro State.

Standardization of intralesional meglumine antimoniate treatment for cutaneous leishmaniasis

Abstract INTRODUCTION: Intralesional treatment for cutaneous leishmaniasis has been applied for over 30 years at the Oswaldo Cruz Foundation, Rio de Janeiro, with good therapeutic results and without relevant systemic toxicity. METHODS Meglumine antimoniate was injected subcutaneously, using a long medium-caliber needle (for example, 30mm × 0.8mm); patients received 1-3 injections, with 15-day intervals. RESULTS The technique is described in detail sufficient to enable replication. CONCLUSIONS: The treatment of cutaneous leishmaniasis with intralesional meglumine antimoniate is a simple, effective, and safe technique, which may be used in basic healthcare settings.

FIRST REPORT OF CUTANEOUS LEISHMANIASIS CAUSED BY Leishmania (Leishmania) infantum chagasi IN AN URBAN AREA OF RIO DE JANEIRO, BRAZIL / Primeiro relato da leishmaniose cutânea causada por Leishmania (Leishmania) infantum chagasiem uma área urbana do Rio de Janeiro, Brasil

SUMMARY American tegumentary leishmaniasis (ATL) is an infectious disease caused by protozoa of the genus Leishmania, and transmitted by sandflies. In the state of Rio de Janeiro, almost all of the cases of American tegumentary leishmaniasis (ATL) are caused by Leishmania (Viannia) braziliensis, while cases of visceral leishmaniasis (VL) are caused by Leishmania (Leishmania) infantum chagasi. The resurgence of autochthonous VL cases in Rio de Janeiro is related to the geographic expansion of the vector Lutzomyia longipalpis and its ability to adapt to urban areas. We report the first case of leishmaniasis with exclusively cutaneous manifestations caused by L. (L.) infantum chagasi in an urban area of Rio de Janeiro. An eighty-one-year-old woman presented three pleomorphic skin lesions that were not associated with systemic symptoms or visceromegalies. Multilocus enzyme electrophoresis identified L. (L.) infantum chagasi, but direct smear and PCR of bone narrow were negative for Leishmania sp. (suggesting exclusively cutaneous involvement). We discuss the different dermatological presentations of viscerotropic leishmaniasis of the New and Old World, and the clinical and epidemiological importance of the case. Etiologic diagnosis of ATL based upon exclusive clinical criteria may lead to incorrect conclusions. We should be aware of the constant changes in epidemiological patterns related to leishmaniases.

RESUMO A leishmaniose tegumentar americana (LTA) é uma doença infecciosa causada por protozoários do gênero Leishmania, transmitida por flebotomíneos. No estado do Rio de Janeiro, quase todos os casos de LTA são causados por Leishmania (Viannia) braziliensis, enquanto a leishmaniose visceral (LV) é causada por Leishmania (Leishmania) infantum chagasi. O ressurgimento de casos autóctones de LV no Rio de Janeiro está relacionado com a expansão geográfica dos vetores Lutzomyia longipalpis e à sua capacidade de se adaptar às áreas urbanas. Relatamos o primeiro caso de leishmaniose com manifestações exclusivamente cutâneas causadas por L. (L.) infantum chagasiem uma área urbana do Rio de Janeiro. Mulher de 81 anos apresentou três lesões cutâneas pleomórficas não associadas a sintomas sistêmicos ou visceromegalias. A eletroforese de enzimas multilocus obtida a partir da lesão cutânea identificou L. (L.) infantum chagasi,por outro lado o exame direto e o PCR da medula óssea foram negativos para Leishmaniasp. (sugerindo acometimento exclusivamente cutâneo). Discutimos as diferentes apresentações dermatológicos da leishmaniose visceral do Novo e Velho Mundo, assim como a importância clínica e epidemiológica deste caso. O diagnóstico etiológico da LTA com base apenas em critérios clínicos pode levar a conclusões incorretas. Devemos estar conscientes das constantes mudanças nos padrões epidemiológicos relacionados à leishmaniose.

Immune reconstitution inflammatory syndrome in HIV and sporotrichosis coinfection: report of two cases and review of the literature

We report 2 cases of patients with immune reconstitution inflammatory syndrome (IRIS) associated with cutaneous disseminated sporotrichosis and human immunodeficiency virus (HIV) coinfection. The patients received specific treatment for sporotrichosis. However, after 4 and 5 weeks from the beginning of antiretroviral therapy, both patients experienced clinical exacerbation of skin lesions despite increased T CD4+ cells (T cells cluster of differentiation 4 positive) count and decreased viral load. Despite this exacerbation, subsequent mycological examination after systemic corticosteroid administration did not reveal fungal growth. Accordingly, they were diagnosed with IRIS. However, the sudden withdrawal of the corticosteroids resulted in the recurrence of IRIS symptoms. No serious adverse effects could be attributed to prednisone. We recommend corticosteroid treatment for mild-to-moderate cases of IRIS in sporotrichosis and HIV coinfection with close follow-up.

Montenegro skinttest and age of skin lesion as redictors of treatment failure in cutaneous leishmaniasis / Intensidade da intradermorreação de Montenegro e tempo de evolução da lesão como preditores de falha na resposta terapêutica da leishmaniose cutânea

A case-control study was conducted to examine the association among the Montenegro skin test (MST), age of skin lesion and therapeutic response in patients with cutaneous leishmaniasis (CL) treated at Evandro Chagas National Institute of Infectious Diseases (INI), Oswaldo Cruz Foundation (FIOCRUZ), Rio de Janeiro, Brazil. For each treatment failure (case), two controls showing skin lesion healing following treatment, paired by sex and age, were randomly selected. All patients were treated with 5 mg Sb5+/kg/day of intramuscular meglumine antimoniate (Sb5+) for 30 successive days. Patients with CL were approximately five times more likely to fail when lesions were less than two months old at the first appointment. Patients with treatment failure showed less intense MST reactions than patients progressing to clinical cure. For each 10 mm of increase in MST response, there was a 26% reduction in the chance of treatment failure. An early treatment - defined as a treatment applied for skin lesions, which starts when they are less than two months old at the first appointment -, as well as a poor cellular immune response, reflected by lower reactivity in MST, were associated with treatment failure in cutaneous leishmaniasis.

Conduzimos estudo caso-controle que verificou a associação entre a intradermorreação de Montenegro (IDRM), o tempo de evolução da lesão e a resposta terapêutica em pacientes com leishmaniose cutânea (LC) atendidos no Instituto de Infectologia Evandro Chagas (INI), Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro, Brasil. Para cada caso com má resposta à terapêutica foram selecionados aleatoriamente dois controles que evoluíram com cicatrização das lesões após o tratamento, pareados por sexo e idade. Todos os pacientes realizaram tratamento com antimoniato de meglumina (Sb5+) IM, na dose de 5 mg Sb5+/kg/dia, continuamente, por 30 dias. Pacientes com LC apresentaram aproximadamente cinco vezes mais chance de falhar quando as lesões apresentavam menos de dois meses de evolução no primeiro dia de atendimento. Pacientes com falha terapêutica apresentaram reações de IDRM menos intensas que pacientes que evoluíram para a cura clínica. A cada 10 milímetros de aumento na resposta à IDRM, houve uma redução de 26% na chance de ocorrência de falha. O tratamento precoce, traduzido pelo tempo de evolução da lesão menor que dois meses no primeiro dia de atendimento, e resposta de imunidade celular deficiente, traduzida por IDRM menos intensa, demonstraram contribuir para a ocorrência de falha terapêutica na leishmaniose cutânea.

Resolution of cttaneous leishmaniasis after acue eczema due to intralesional mmeglumine antimoniate / Resolução de leishmaniose cutânea após eczema agudo devido a antimoniato de meglumina intralesional

We report a case of a 42 year-old female, who came to a leishmaniasis reference center in Rio de Janeiro, Brazil, presenting a cutaneous leishmaniasis lesion in the right forearm. Treatment with low-dose intramuscular meglumine antimoniate (MA) (5 mg Sb5+/kg/day) was initiated, with improvement after 28 days, although with the development of generalized eczema. After 87 days, the lesion worsened. Patient refused treatment with amphotericin B. MA was then infiltrated in the lesion, in two sessions, resulting in local eczema, with bullae formation; however, twenty days after, both the ulcer and eczema receded. Intralesional administration of MA should be used carefully when previous cutaneous hypersensitivity is detected.

Relatamos caso de paciente de 42 anos atendida em centro de referência em leishmanioses no Rio de Janeiro, Brasil, apresentando lesão de leishmaniose cutânea no antebraço direito. Iniciado tratamento com baixa dose de antimoniato de meglumina (AM) intramuscular (5 mg Sb5+/kg/dia), houve melhora após 28 dias, porém com desenvolvimento de eczema generalizado. Após 87 dias, notou-se piora da lesão. A paciente recusou o tratamento com anfotericina B. Infiltrou-se AM na lesão em duas sessões, resultando em eczema local com bolhas. Entretanto, 20 dias depois, tanto a úlcera quanto o eczema regrediram. A administração intralesional do AM deve ser utilizada com cautela em pacientes com hipersensibilidade cutânea a este fármaco.

Factors associaeed to adherence to different tratment schemes with meglumine aantimoniate in a clinical trial for cutaneous leishmaniasis / Fatores associados à adesão a diferentes esquemas de tratamento com antimoniato de meglumina em ensaio clínico para leishmaniose cutânea

The favorable outcome of the treatment of a disease is influenced by the adherence to therapy. Our objective was to assess factors associated with adherence to treatment of patients included in a clinical trial of equivalence between the standard and alternative treatment schemes with meglumine antimoniate (MA) in the treatment of cutaneous leishmaniasis (CL), in the state of Rio de Janeiro. Between 2008 and 2011, 57 patients with CL were interviewed using a questionnaire to collect socioeconomic data. The following methods were used for adherence monitoring: counting of vial surplus, monitoring card, Morisky test and modified Morisky test (without the question regarding the schedule); we observed 82.1% (vial return), 86.0% (monitoring card), 66.7% (Morisky test) and 86.0% (modified Morisky test) adherence. There was a strong correlation between the method of vial counting and the monitoring card and modified Morisky test. A significant association was observed between greater adherence to treatment and low dose of MA, as well as with a lower number of people sleeping in the same room. We recommend the use of the modified Morisky test to assess adherence to treatment of CL with MA, because it is a simple method and with a good performance, when compared to other methods.

O desfecho favorável ao tratamento de uma enfermidade é influenciado pela adesão à terapia. Objetivamos avaliar fatores associados à adesão ao tratamento dos pacientes incluídos em ensaio clínico de equivalência entre o esquema de tratamento padrão e alternativos com antimoniato de meglumina (AM) no tratamento da leishmaniose cutânea (LC) no estado do Rio de Janeiro. Entre 2008 e 2011, 57 pacientes com LC foram entrevistados através de questionário para coleta de dados socioeconômicos. Para monitorização da adesão foram utilizados os seguintes métodos: contagem de ampolas excedentes, cartão de acompanhamento, teste de Morisky e teste de Morisky modificado (sem a pergunta referente ao horário). Observou-se adesão de 82,1% (devolução de ampolas), 86,0% (cartão de acompanhamento), 66,7% (teste de Morisky) e 86,0% (teste de Morisky modificado). Houve forte concordância entre o método contagem de ampolas e cartão de acompanhamento, bem como teste de Morisky modificado. Verificou-se associação significativa entre maior adesão ao tratamento e baixa dose de AM, bem como com menor número de pessoas dormindo no mesmo quarto. Recomendamos a utilização do teste de Morisky modificado na avaliação da adesão ao tratamento da LC com AM por ser método simples e com bom desempenho quando comparado aos outros testes.

Social epidemiology, education, and health promotion in infectious disease

This short communication discusses a project in Rio de Janeiro involving an attempt at imparting clinical and social epidemiology knowledge through educational initiatives. In small groups, social epidemiology was discussed in the context of a clinical/epidemiological project on various infectious diseases. Relevant knowledge was produced collaboratively by a multidisciplinary team of clinical research and project participants, comprising patients, relatives, friends, and health workers. An improvement in the learning capacity of participants was observed, fostering active appropriation of scientific knowledge. In dealing with infectious disease, social epidemiology contributes to the development of new strategies for collaborative research and disease prevention.

Esta comunicação discute um projeto desenvolvido no Rio de Janeiro, Brasil, que vincula epidemiologia clínica e epidemiologia social por meio de iniciativas educacionais. Abordagens da epidemiologia social foram utilizadas num projeto clínico-epidemiológico em doenças infecciosas, no qual a construção do conhecimento envolveu os próprios participantes (pacientes, familiares, amigos e trabalhadores da saúde) juntamente com a equipe multidisciplinar de pesquisas clínicas. Foi observada uma melhoria na capacidade de aprendizagem dos participantes que contribuiu para a apropriação ativa do conhecimento científico. Ao lidar com doenças infecciosas, a epidemiologia social favorece o desenvolvimento de novas estratégias de investigação colaborativa e de prevenção da doença.

Acroangiodermatite (pseudossarcoma de Kaposi): uma condição raramente reconhecida. Um caso na planta do pé associado a insuficiência venosa crônica / Acroangiodermatitis (pseudo-Kaposi sarcoma): a rarely-recognized condition. A case on the plantar aspect of the foot associated with chronic venous insufficiency

A acroangiodermatite ou pseudossarcoma de Kaposi é entidade angioproliferativa incomum relacionada a insuficiência venosa crônica, fístulas arteriovenosas, membros paralisados, cotos de amputação, síndromes vasculares e condições trombóticas. Apresenta-se, em geral, como máculas, pápulas ou placas purpúricas no dorso dos pés (especialmente hálux) e maléolos. Relatamos um caso de acroangiodermatite afetando a região plantar, por dois anos sem diagnóstico, para o qual a coloração histológica por hematoxilina-eosina e a marcação imuno-histoquímica com CD34 foram decisivas. A paciente tinha insuficiência venosa crônica e a lesão respondeu bem ao uso de bandagens elásticas e repouso com a perna elevada.

Acroangiodermatitis, often known as pseudo-Kaposi sarcoma, is an uncommon angioproliferative entity related to chronic venous insufficiency, arteriovenous fistulae, paralysed limbs, amputation stumps, vascular syndromes and conditions associated with thrombosis. It presents most frequently as purple macules, papules or plaques in the dorsal aspects of the feet, especially the toes, and the malleoli. We report a case of acroangiodermatitis in the plantar aspect of the foot, misdiagnosed for two years, in which haematoxylin-eosin hystopathological stain and immunolabeling with CD34 histochemistry examination were decisive for diagnosis. Patient had chronic venous insufficiency. The lesion responded well to the treatment with a combination of leg elevation and compression.

American cutaneous leishmaniasis caused by Leishmania (Viannia) braziliensis resistant to meglumine antimoniate, but with good response to pentamidine: a case report / Leishmaniose cutânea americana causada pela Leishmania (Viannia) braziliensis resistente ao antimoniato de meglumina e com boa resposta terapêutica à pentamidina: relato de um caso

Relatamos um caso de um militar brasileiro com leishmaniose cutânea, cuja lesão reativou após dois tratamentos sistêmicos com antimoniato de meglumina. Foi tratado com anfotericina B, mas precisou interromper por intolerância à medicação. Após isolamento de Leishmania sp, seis infiltrações intralesionais de antimoniato de meglumina foram realizadas, sem resposta. Promastigotas de Leishmania sp. foram novamente isoladas. Foi submetido a tratamento intramuscular com pentamidina (4mg/kg). Parasitas da primeira e segunda biópsias foram identificados como Leishmania (Viannia) braziliensis; os da primeira biópsia eram mais sensíveis ao antimoniato de meglumina in vitro do que os da segunda biópsia. A lesão não reativou.

This is a case report of a Brazilian soldier with cutaneous leishmaniasis. The lesion relapsed following two systemic treatments with meglumine antimoniate. The patient was treated with amphotericin B, which was interrupted due to poor tolerance. Following isolation of Leishmania sp., six intralesional infiltrations of meglumine antimoniate resulted in no response. Leishmania sp promastigotes were again isolated. The patient was submitted to intramuscular 4mg/kg pentamidine. Parasites from the first and second biopsies were identified as Leishmania (Viannia) braziliensis; those isolated from the first biopsy were more sensitive to meglumine antimoniate in vitro than those isolated from the second biopsy. No relapse was observed.

Análise do protocolo complementar de investigação diagnóstica dos casos de hanseníase em menores de 15 anos nos municípios prioritários do estado do Rio de Janeiro em 2009 e 2010 / Analysis of the additional protocol of diagnostic investigation of cases of leprosy in children under 15 years in priority municipalities in the state of Rio de Janeiro in 2009 and 2010

Introdução: A ocorrência de hanseníase em crianças e adolescentes é preocupante porque seu aumento é considerado indicador de maior gravidade da endemia hansênica. O Ministério da Saúde instituiu, em 2008, o Protocolo Complementar de Investigação Diagnóstica em Menores de 15 Anos (PCID < 15), a ser preenchido pelos profissionais das unidades de saúde quando diagnosticado um caso de hanseníase nesta faixa etária. O presente estudo pretendeu analisar criticamente as informações contidas nas fichas do PCID < 15, nos municípios prioritários do estado do Rio de janeiro. Métodos: dos campos; 15,4% destes tiveram percentual de pre. Foi realizado estudo seccional retrospectivo, utilizando análise estatística descritiva das informações contidas nos registros dos PCID < 15 nos anos de 2009 e 2010, dos municípios considerados prioritários para a Gerência de Dermatologia Sanitária da Secretaria de Estado de Saúde do Rio de Janeiro. Foi analisada a completitude dos campos, incluindo a consistência das informações daqueles referentes à classificação operacional e número de lesões de pele, além da análise epidemiológica das 172 fichas incluídas no estudo. Resultados: O percentual de preenchimento foi excelente, na maioria dos campos; 15,4% destes tiveram percentual de pre enchimento considerado regular (itens “prontuário”, de refletir a situação epidemiológica dos pacientes me“tempo de residência”, “número de pessoas da família com problemas de pele”, e “cicatriz de BCG”). Não foi analisada a porcentagem de preenchimento do campo “grau de incapacidade física”. Ocorreu forte concordância (coeficiente Kappa k = 0,76, p < 0,0001) entre os campos “número de lesões de pele” e “classificação operacional”, com apenas 7% de casos inconsistentes...

Introduction: The occurrence of leprosy in children and adolescents is of concern because its increase is consid-ered an indicator of severity of leprosy. The Ministry of Health established in 2008 an Additional Protocol of Di-agnostic Research in Children under 15 Years (PCID <15), to be fulfilled by professionals in the health units when-ever a case of leprosy in patients in this age group is diag-nosed.The present study aimed to critically analyze the information contained in the files of the PCID < 15, in priority municipalities of Rio de Janeiro State. Methods: We conducted a retrospective cross-sectional study us-ing descriptive statistics, based on the evaluation of the information contained in the records of leprosy cases registered in PCID <15 years in 2009 and 2010 from the priority municipalities according to the cri-teria of the Sanitary Dermatology Department of the Rio de Janeiro State Health Secretariat. We analyzed the completeness of fields including the consistency of the information fields according to the operational clas-sification and number of skin lesions, contained in the 172 records included in the study. Results: Excellent per-centage of completion, according to the parameters of SINAN, occurred in most fields, with only 15.4% of fields with regular percentage of completion (“records”, “residence time”, “number of people in the family with skin diseases”, and “BCG vaccination scar”). The study revealed a strong concordance (Kappa coefficient k = 0.76, p <0.0001) between the fields number skin le-sions and operational classification, with inconsistency in only 7% of cases. There was a slight predominance of females, 92.3% of cases between 5 and 14 years, 71.6% diagnosed with six months or more after the onset of signs and symptoms, 58.6% of patients had history of leprosy in the family, 85% of cases had up to 5 skin le-sions and 83.6% had a BCG scar...

Introducción: La lepra en los niños, niñas y adolescentes es preocupante, ya que su incremento es un indicador de lepra endémica más grave. El Ministerio de Salud estableció en 2008, el Protocolo de Investigación adi-cional de diagnóstico en los niños menores de 15 años (Pontificio Consejo <15), que se completará por los pro-fesionales en las unidades de salud cuando un caso de lepra diagnosticados en este grupo de edad. El presente estudio tuvo como objetivo analizar críticamente la in-formación contenida en los archivos de los municipios prioritarios PCID menores de 15 en el estado de Río de Janeiro. Métodos: Se realizó un estudio retrospectivo de corte transversal mediante el análisis estadístico des-criptivo de la información contenida en los registros de PCID <15 años en 2009 y 2010, las ciudades consideradas prioritarias para la gestión de Dermatología Sanitaria de la Secretaría de Salud del Estado de Río de Janeiro. Se analizó la totalidad de los campos, incluyendo la consis-tencia de la información de los que operan en la clasi-ficación y el número de lesiones en la piel, además de un análisis epidemiológico de 172 fichas incluidas en el estudio. Resultados: El porcentaje de cumplimiento fue excelente en la mayoría de los campos, el 15,4% porcen-taje de pases completos de ellas fueron consideradas regular (artículos de “grabación”, “tiempo de residencia”, “número de miembros de la familia con problemas de la piel”, y “cicatriz de la BCG”). No se analizó el porcentaje de finalización de la “discapacidad física”. Hubo un fuerte acuerdo (coeficiente kappa k = 0,76, p <0,0001) entre los campos “número de lesiones en la piel” y de operación “clasificación” con sólo el 7% de los casos inconsisten-tes...
