Genital ulcers caused by sexually transmitted agents,

Abstract Genital ulcers (GUs) represent a diagnostic challenge and can be secondary to neoplastic and inflammatory processes of different causes. Among those of infectious etiology, there are sexually transmitted infections (STIs), a very frequent reason for seeking the health service. The most common agents are herpes simplex virus and Treponema pallidum and, more rarely, Haemophilus ducreyi, Klebsiella granulomatis and Chlamydia trachomatis. A careful dermatological examination offers important diagnostic elements; however, atypical manifestations are very common. Distinctive characteristics of ulcers to look out for include their margin, edge, bottom, and base. Regional lymph node chain alterations should be evaluated regarding their number, size, mobility, consistency, inflammation, and pain on palpation. Diagnostic tests have variable sensitivity and specificity, and molecular tests are currently considered the reference exams. The rapid immunochromatographic tests represented a significant advance, as they can be performed with blood obtained from the digital pulp, offer results in up to 30 minutes, and do not require a laboratory structure. The treatment of persons affected by GU/STIs must be immediate, as it aims to prevent complications, as well as reduce transmission. It is not always considered that people with GUs/STIs have varying degrees of depression, anxiety, and self-reproach, with an impact on relationships. Establishing a bond and trusting the professional is essential for adherence to treatment and preventive measures that must be discussed individually.

Case for diagnosis. Atypical genital lesion

Abstract: We present a case of a penile lesion with a clinical appearance similar to Mondor penile disease (thrombosis of the dorsal vein of the penis) or penile sclerosing lymphangitis. Laboratory evaluation, however, showed a solid lesion, with no vascular component to Doppler ultrasonography and no treponema to immunohistochemistry. Histological and serological tests were compatible with secondary syphilis. The authors reinforce the need for the inclusion of syphilis in the differential diagnosis of penile cord injuries.

Effectiveness of syndromic management for male patients with urethral discharge symptoms in Amazonas, Brazil

Abstract: Background: Urethral discharge syndrome (UDS) is characterized by the presence of purulent or mucopurulent urethral discharge.The main etiological agents of this syndrome are Neisseria gonorrhoeae and Chlamydia trachomatis. Objectives: To evaluate the effectiveness of the syndromic management to resolve symptoms in male urethral discharge syndrome cases in Manaus, Amazonas, Brazil. Methods: Retrospective cohort of male cases of urethral discharge syndrome observed at a clinic for sexually transmitted disease (STD) in 2013. Epidemiological and clinical data, as well as the results of urethral swabs, bacterioscopy, hybrid capture for C.trachomatis, wet-mount examination, and culture for N.gonorrhoeae, were obtained through medical chart reviews. Results: Of the 800 urethral discharge syndrome cases observed at the STD clinic, 785 (98.1%) presented only urethral discharge syndrome, 633 (79.1%) returned for follow-up, 579 (91.5%) were considered clinically cured on the first visit, 41(6.5 %) were considered cured on the second visit, and 13(2.0%) did not reach clinical cure after two appointments. Regarding the etiological diagnosis, 42.7% of the patients presented a microbiological diagnosis of N.gonorrhoeae, 39.3% of non-gonococcal and non-chlamydia urethritis, 10.7% of C.trachomatis and 7.3% of co-infection with chlamydia and gonococcus. The odds of being considered cured in the first visit were greater in those who were unmarried, with greater schooling, and with an etiological diagnosis of gonorrhea. The diagnosis of non-gonococcal urethritis reduced the chance of cure in the first visit. Study limitation: A study conducted at a single center of STD treatment. Conclusion: Syndromic management of male urethral discharge syndrome performed in accordance with the Brazilian Ministry of Health STD guidelines was effective in resolving symptoms in the studied population. More studies with microbiological outcomes are needed to ensure the maintenance of the syndromic management.

Assessment of completion of forms requesting skin biopsies / Avaliação do preenchimento de solicitações de biópsias da pele

BACKGROUND: Information contained in request forms for histopathological examinations is essential for interpreting tissue changes observed in microscopy. OBJECTIVE: To determine the adequacy of information provided on forms requesting skin biopsies. METHOD: Assessment, in two health institutions, of 647 forms requesting skin biopsies in order to determine the completeness on the forms of the clinical details/items considered necessary for undertaking skin biopsies. RESULTS: Of the total 18 items on the forms, 7 were found to relay complete information in under 10% of the forms and only 9 items were correctly completed in over 80% of the requests. CONCLUSION: We concluded that information on many of the essential items required for a correct interpretation of the anatomopathologic examination was missing from the request forms.

Intervenção de base comunitária para a prevenção das DST/Aids na região amazônica, Brasil / Community-based intervention to control STD/AIDS in the Amazon region, Brazil / Community-based intervention to control STD/AIDS in the Amazon region, Brazil

OBJETIVO: Descrever estudo de caso de intervenção de base comunitária, desenvolvido na perspectiva construcionista-emancipatória, para o controle das DST/Aids. MÉTODOS: Estudo descritivo desenvolvido no município de Manacapuru, Amazonas, de 1997-2004, sobre a utilização de procedimentos desenhados em colaboração com agentes governamentais, profissionais de saúde e comunidade. Foram levantados dados sobre a dinâmica da prostituição e a venda de preservativos na cidade, características comportamentais, avaliação do processo e da assistência às DST/Aids. Sincronicamente, estabeleceram-se ações de prevenção e assistência na rede pública de saúde às DST, centro de testagem, sistema de vigilância epidemiológica, e capacitação de trabalhadoras do sexo. RESULTADOS: Observou-se o fortalecimento das trabalhadoras do sexo como multiplicadoras e sua legitimação como cidadãs e agentes de saúde em projetos com travestis, homossexuais e escolares. Houve incremento da venda de preservativos na cidade, da utilização de preservativos entre trabalhadoras do sexo, redução das DST bacterianas e estabilização da ocorrência de infecção pelo HIV/Aids e sífilis congênita. A sustentabilidade do programa de intervenção estudado, organizado no âmbito do Sistema Único de Saude, foi estimulada pela pactuação política garantindo sede e orçamento regulamentado em lei municipal, e pelo debate permanente dos resultados do processo e programa. CONCLUSÕES: O estudo fortaleceu a noção de que o controle efetivo das DST/Aids depende de uma abordagem sinérgica que combine intervenções no plano individual (biológica-comportamental), sociocultural e programático.

OBJECTIVE: To describe a case study of community-based intervention, developed in a constructionist-emancipatory framework to control STD/AIDS. METHODS: Descriptive study developed in the town of Manacapuru, in the state of Amazonas, from 1997 to 2004, focusing on procedures designed in collaboration with government agents, health professionals and the community. Data on the dynamics of prostitution and condom sales in this town, preventive practices and STD/AIDS care and process assessment were collected. Actions targeting STD prevention and care in the public healthcare system, a testing center, an epidemiological surveillance system and sex workers' qualification were established concomitantly. RESULTS: It was observed the strengthening of sex workers as peer educators and their legitimization as citizens and health agents in projects involving transvestites, homosexuals and students. There was an increase in condom sales in town, as well as in condom use among sex workers; reduction in bacterial STD; and stabilization of the incidence of HIV/AIDS infections and congenital syphilis. The sustainability of the intervention program studied, organized within the sphere of action of the Sistema Único de Saúde (National Health System), was promoted by a political pact, which guaranteed headquarters and municipal law-regulated budget, as well as by the constant debate over the process and program results. CONCLUSIONS: The study strengthened the notion that effective control of STD/AIDS depends on a synergic approach that combines interventions on individual (biological-behavioral), sociocultural and programmatic levels.

Rapid tests for diagnosing syphilis: validation in an STD clinic in the Amazon Region, Brazil

Correct, early diagnosis and treatment of syphilis are essential for its control. Traditional diagnostic tests depend on specialized equipment, installations, and human resources. In the search for quick, simple tests, a project was conducted on the validation and reproducibility of four different tests, previously assessed by WHO reference laboratories. The study also verified the operational characteristics and acceptance by patients and health professionals. Samples obtained at an STD clinic were from 541 and 248 patients with 51 and 52 positive results according to FTA-Abs (gold standard) in studies 1 and 2, respectively. The sensitivity varied from 84 to 96 percent, specificity was greater than 98 percent, and PPV was > 90 percent. Reproducibility was > 97 percent and kappa index 0.94, comparing the results obtained by different health workers. The tests took less than 20 minutes to perform, and more than 90 percent of patients agreed to wait up to two hours for the results. The tests presented the necessary requirements for use in diagnosis of syphilis, thus providing an additional option for controlling this disease.

O diagnóstico e o tratamento corretos e precoces da sífilis são essenciais para o seu controle. Os testes diagnósticos tradicionais dependem de equipamentos, instalações e recursos humanos especializados. Na busca de testes de execução simplificada e rápida, realizou-se projeto de validação e da reprodutibilidade de quatro diferentes testes anteriormente avaliados pelos laboratórios de referência da Organização Mundial da Saúde. Verificaram-se também as características operacionais e aceitabilidade dos pacientes e dos profissionais de saúde. As amostras obtidas numa clínica de DST constaram de 541 e 248 pacientes com 51 e 52 positivos no FTA-Abs (padrão ouro) nos estudos 1 e 2, respectivamente. A sensibilidade variou entre 84 e 96 por cento, especificidade superior a 98 por cento e valor preditivo positivo > 90 por cento. A reprodutibilidade foi superior a 97 por cento e 0,94 no índice de kappa, comparando-se os resultados obtidos pelos diferentes profissionais. A execução dos testes foi de menos de vinte minutos, e mais de 90 por cento dos pacientes concordaram em esperar o seu resultado até duas horas. Os testes apresentaram requisitos necessários para serem empregados no diagnóstico da sífilis, dando assim mais uma opção para o controle desta infecção.
