RESUMO
The aim of this study was to identify polymorphisms in the folp1, gyrA, and rpoB genes in leprosy patients treated in Amazonas State, Brazil. Among 197 slit-skin smear samples from untreated or relapsed patients, we found three cases of primary resistance to rifampin and one confirmed case of multidrug resistance.

The aim of this study was to investigate sensitivity disorders in the oral cavity related to the presence of Mycobacterium leprae in the saliva of treatment-naïve patients with leprosy in the state of Amazonas, Brazil. A cross-sectional study was conducted involving 45 subjects with leprosy. The subjects were interviewed to evaluate the sensitivity of the oral cavity. For the detection of M. leprae, saliva and slit-skin smear samples were collected. The samples were analysed using a bacteriological index (BI) protocol and the real-time quantitative polymerase chain reaction (qPCR). The results indicated that 15 of the 45 (33.3%) subjects with leprosy showed decreased oral sensitivity, which confirmed the importance of the oral cavity sensitivity evaluation. There was not a direct relationship between the presence of M. leprae in saliva and changes in oral sensitivity. Positive saliva qPCR results from six (31.6%) of 19 paucibacillary (PB) patients suggested the possibility of a new site for sample collection. Positive results using these diagnostic techniques (BI, slit-skin smear and saliva qPCR) increased to 55.5%, thus opening the possibility of combining these different techniques to increase the rate of positive diagnoses, especially in PB patients.

BACKGROUND: After the introduction of the multidrug therapy, there was a decline in the coefficients of prevalence and detection of new cases of leprosy. However, the records of drug resistance and relapses are threatening factors in leprosy control. Hence, new alternative schemes and monitoring of adverse effects to avoid treatment abandonment are important considerations. OBJECTIVE: Describe the side effects of a multidrug regimen containing minocycline, ofloxacin, and clofazimine in multibacillary leprosy patients. METHODS: We conducted a prospective, descriptive, and observational study with multibacillary patients, including cases of intolerance to standard MDT and relapses. The study was carried out at Fundação Alfredo da Matta (Alfredo da Matta Foundation), in Manaus, Amazonas, from April 2010 to January 2012. The patients received alternative therapy, which consisted of daily self-administered doses of 100mg of minocycline, 400 mg of ofloxacin, and 50mg of clofazimine and a supervised monthly dose of 300mg of clofazimine for six months, followed by eighteen months of daily doses of ofloxacin 400mg, clofazimine 50mg, and a supervised monthly dose of clofazimine 300mg. RESULTS: Twenty-one cases were included. Mild and transitory side effects occurred in 33.3% of patients. Of the total episodes, 45.9% were attributed to ofloxacin and they included abdominal pain, nausea, vomiting, headache, and insomnia; 21.6% were due to clofazimine, with 100% of patients presenting skin pigmentation. The mean time for the development of adverse effects after beginning the therapy was 15.2 days. CONCLUSION: All patients tolerated the drugs well, and compliance was satisfactory, with no serious events. Unlike other standard MDT studies had shown, no treatment was stopped due to side effects. Nevertheless, patient follow-up and studies with bigger samples are necessary to guarantee the efficacy and safety of the alternative regimen as a second-line scheme in multi-drug therapy.

FUNDAMENTOS: Após introdução do esquema poliquimioterápico padrão, houve declínio nos coeficientes de prevalência e detecção de casos novos; entretanto, os registros de resistência medicamentosa e recidivas representam ameaça para o controle da hanseníase. Dessa forma, a proposição de novos esquemas alternativos e a necessidade de monitorar efeitos adversos são importantes para evitar o abandono do tratamento. OBJETIVO: Descrever efeitos adversos do esquema alternativo contendo clofazimina, ofloxacina e minociclina em pacientes com hanseníase multibacilar. MÉTODOS: Estudo prospectivo, descritivo e observacional de casos multibacilares, incluindo recidivas ou intolerância à poliquimioterapia padrão, realizado na Fundação Alfredo da Matta, Manaus, Amazonas, de abril de 2010 a janeiro de 2012. Os indivíduos receberam a terapia composta de doses diárias auto-administradas de 100mg de minociclina, 400mg de ofloxacina e 50mg de clofazimina e mensais supervisionadas de 300mg de clofazimina por seis meses, seguidas de 18 meses de doses diárias de ofloxacina 400mg, clofazimina 50 mg e supervisionadas mensais de clofazimina 300mg. Resultados: 21 pacientes foram incluídos. Efeitos adversos leves e transitórios foram observados em 33,3% dos pacientes; 45,9% foram atribuídos à ofloxacina, como dor abdominal, náuseas, vômitos, cefaléia e insônia; 21,6% foram associados à clofazimina, com relatos e observação em 100% dos pacientes de hiperpigmentação cutânea. O tempo médio de desenvolvimento das reações adversas a partir do início do esquema foi de 15,2 dias. ...

BACKGROUND: The Acquired Immunodeficiency Syndrome (AIDS) constitutes a sub-epidemic in Brazil. Due to the increasing number of women infected by the virus, the vertical transmission increased substantially, and due to the lack of adequate prophylactic treatment, many children are infected and show manifestations of the disease in early ages. Multiple systems are affected by the HIV virus, and the skin is often the first organ to be involved. OBJECTIVES: The objective of this study is to analyze the clinic, dermatological and epidemiological profiles of children carriers of the virus in the City of Manaus aiming at identifying the most frequent dermatoses that affect these children and try to relate these dermatoses to the immunologic deterioration. METHODS: A study was conducted where children carriers of the HIV virus from the Fundação Alfredo da Matta and Fundação de Medicina Tropical were studied from March 2007 to July 2008. These children were submitted to dermatological and laboratorial exams such as viral load dosage and CD4+ and CD8+ counts. RESULTS: During the study period, 70 HIV + children were examined; all of them had AIDS and had been contaminated by vertical transmission. The average number of dermatoses by children was 1.73, and 95.5% had at least one dermatosis during the study period. The most frequent manifestations were atopic dermatitis (22.9%), childhood prurigo (20%) and warts (18,6%). CONCLUSIONS: Children with HIV/AIDS have more skin disorders than children without HIV/AIDS. There was no statistical difference between the children in the group using ARVT and the group that wasn't using it.

FUNDAMENTOS: A Síndrome da Imunodeficiência Adquirida (AIDS) tem se configurado como uma sub-epidemia no Brasil, devido ao crescente número de mulheres infectadas pelo vírus, a transmissão vertical aumentou significativamente, e devido à falta de tratamento profilático adequado, muitas crianças são infectadas e convivem com as manifestações da doença precocemente. Múltiplos são os sistemas acometidos pelo vírus HIV, sendo a pele muitas vezes o primeiro órgão acometido. OBJETIVOS: O estudo teve por objetivo analisar o perfil clínico-dermatológico e imunológico das crianças portadoras do vírus HIV na cidade de Manaus com a finalidade de identificar as dermatoses mais freqüentes que as acometem e relacioná-las com a deterioração de seu sistema imunológico. MÉTODOS: Realizou-se um estudo onde foram acompanhadas entre março de 2007 a julho de 2008, crianças portadoras do vírus HIV atendidas na Fundação de Medicina Tropical do Amazonas. Estas foram submetidas a exame dermatológico e a exames laboratoriais como dosagem de carga viral, CD4+, CD8+. RESULTADOS: Durante o período estudado, foram atendidas 70 crianças HIV+, todas já apresentavam AIDS e tinham sido contaminadas por transmissão vertical. A média de dermatose por criança foi de 1,73 sendo que 95,5% apresentaram pelo menos uma dermatose. As manifestações mais freqüentes foram: dermatite atópica (22,9%), prurigo estrófulo (20%) e verruga (18,6%). CONCLUSÃO: As crianças com HIV/AIDS apresentaram mais dermatoses do que as crianças sem HIV/AIDS. Não houve diferença estatística em relação às dermatoses entre o grupo de crianças que estava em uso de Terapia antiretroviral (TARV) e o que não estava.

UNLABELLED: Recently antimicrobials of the fluoroquinolone class (pefloxacin and ofloxacin) were found far more effective against Mycobacterium leprae in studies with both mice and patients than dapsone and clofazimine. As multicentre trial participants, we evaluated the therapeutic efficacy, in terms of rate of relapse, of two new multidrug regimens containing ofloxacin, comparing them to 1 year and 2 years of standard WHO-MDT regimen in multibacillary (MB) leprosy patients. A total of 198MB patients were recruited to participate in a randomized, double-blind trial. Among those, 53 patients were treated with 1 year of WHO-MDT (a regimen including dapsone, clofazimine, and rifampin), 55 patients received 1 year of WHO-MDT plus an initial 1 month of daily ofloxacin, 63 patients were treated with 1 month of daily rifampin and daily ofloxacin, whereas 27 were treated with 2 years of WHO-MDT. Patients were regularly monitored for signs of relapse, in at least 7 years follow-up after being released from treatment. RESULTS: Relapse occurred in those treated with 1-month regimen alone at a significant higher rate (P < 0.001): 388%, whereas in the other three regimens that included WHO-MDT it ranged from 0 to 5%. This study found that a short-course treatment for MB patients with rifampicin-ofloxacin combination had a higher failure rate. The addition of one month of daily ofloxacin to 12 months MB WHO-MDT did not increase its efficacy.

BACKGROUND: Sexually transmitted diseases in children remain a public health concern that is relatively ignored. Further data are required on the management of these diseases and their association with child sexual abuse. OBJECTIVES: To describe the clinical and epidemiological profile of sexually transmitted diseases in children receiving care at a referral center in the city of Manaus, Amazonas, Brazil. METHODS: A descriptive, exploratory study was conducted to evaluate the clinical, epidemiological and laboratory characteristics of the sexually transmitted diseases (STD) found in children who received care at this clinic between January 2003 and December 2007. RESULTS: A total of 182 children with STDs were included in the study. The majority were female (65.4%), dark-skinned and with a mean age of 8.5 years. Furthermore, 89% were from the city of Manaus and their parents were usually responsible for having brought them to the clinic. Genital warts constituted the principal diagnosis in children of both sexes and 90.1% of the children had only one STD. CONCLUSIONS: The frequencies and clinical characteristics of the STDs in the children in this study were similar to data reported in the literature. Although the signs and symptoms of the STDs found in these children do not, in themselves, constitute reliable parameters by which to confirm abuse, professionals should always be alert to this possibility, since these diseases may represent a sign of sexual offenses that may be dissimulated and repetitive.

FUNDAMENTOS: Doenças Sexualmente Transmissíveis em crianças permanecem um problema de saúde pública pouco estudado, sendo ainda necessários esclarecimentos sobre seu manejo e a relação destas com o abuso sexual infantil. OBJETIVOS: Descrever o perfil clínico-epidemiológico das Doenças Sexualmente Transmissíveis em crianças atendidas em centro de referência na cidade de Manaus. MÉTODOS: Realizou-se estudo descritivo exploratório para verificar características clínicas, epidemiológicas e laboratoriais das Doenças Sexualmente Transmissíveis em crianças atendidas durante o período de janeiro/2003 a dezembro/2007. RESULTADOS: Foram incluídas no estudo 182 crianças que apresentavam DST. A maioria era do sexo feminino (65,4 por cento) e de cor parda; a média de idade foi de 8,5 anos; 89 por cento eram procedentes da cidade de Manaus; os pais foram os principais acompanhantes na consulta; verruga genital foi o principal diagnóstico em ambos os sexos; e, 90,1 por cento apresentavam apenas uma DST. CONCLUSÃO: As frequências e características clínicas das DST nas crianças do estudo não diferiram do encontrado na literatura. Embora, com base em sinais e sintomas referentes tão somente às DST nas crianças, não se tenham parâmetros fidedignos de confirmação de abuso, deve-se sempre estar alerta para esta possibilidade, visto que estas doenças podem ser sinalizadoras de ofensas sexuais, por vezes, dissimuladas e repetidas.

FUNDAMENTOS: A pitiríase versicolor (tinha versicolor) é uma micose superficial crônica, causada por leveduras do gênero Malassezia spp. comensais das camadas queratinizadas da pele e que, sob determinadas condições ainda não esclarecidas, se torna patogênica, determinando as manifestações clínicas da doença. É uma dermatose recidivante e, mesmo após tratamento, pode deixar hipopigmentação persistente, causando problemas sociais aos indivíduos acometidos. OBJETIVO: Descrever as características clínicas e epidemiológicas de pacientes com diagnóstico de tinha versicolor atendidos em uma unidade de referência em Dermatologia (Fundação Alfredo da Matta). MÉTODOS: Estudo de série de casos em que foram detalhadas as manifestações cutâneas e as características epidemiológicas de pacientes atendidos na Fundação Alfredo da Matta com diagnóstico de tinha versicolor. RESULTADOS: Cento e dezesseis pacientes foram incluídos no estudo no período de janeiro a agosto de 2008. A maioria dos indivíduos é do sexo masculino, de cor parda, da faixa etária jovem e formada por estudantes, que apresentavam fatores predisponentes ao surgimento das manchas. Também a maioria apresentava lesões extensas e história passada da doença. CONCLUSÃO: O estudo mostrou alta proporção de indivíduos com quadros extensos e de longa duração da doença.
BACKGROUND: Pityriasis versicolor (tinea versicolor) is a chronic superficial mycosis caused by yeasts of the Malassezia spp. genus commensal of the keratinized layers of the skin. Under conditions not yet understood, it becomes pathogenic determining the clinical manifestations of the disease. It is a recurrent skin condition and persistent hypopigmentation may remain after treatment, causing social problems to those affected. OBJECTIVE: To describe the clinical and epidemiological features of patients diagnosed with tinea versicolor treated at a referral center for dermatology (Alfredo da Matta Foundation). METHODS: Case-studies in which cutaneous manifestations and epidemiological characteristics of patients diagnosed with tinea versicolor treated at Alfredo da Matta Foundation were detailed. RESULTS: One hundred and sixteen patients were included in the study from January to August 2008. Most subjects were male, of mixed ethnicity and young age. Most were students who were predisposed to the development of macules. The majority had extensive injuries and past history of the disease. CONCLUSION: The results revealed a high proportion of individuals with extensive clinical manifestations and duration of the disease.

BACKGROUND: Teledermatology is seldom used in Brazil, although some incipient initiatives have been implemented in the state of Amazonas. Further studies are still required to confirm the feasibility and efficacy of this diagnostic tool. OBJECTIVES: To evaluate the efficacy of an asynchronous method of teledermatology using simple, inexpensive technological resources. METHODS: One hundred and seventy-four patients were examined by four dermatologists, two clinic-based dermatologists, who diagnosed the patients following live examination (A1 and A2), and two consultant specialists in image dermatology, who reached diagnoses by examining images of the lesions and the patients' clinical histories (B1 and B2). The agreement between live examination and examination of images was evaluated. RESULTS: Agreement between the two live examiners (A1 and A2) with respect to the principal diagnosis was 83.3% compared to 81.0% between the physicians who diagnosed by examining images (B1 and B2). Agreement between the principal diagnosis established by live examination and that obtained from examining images ranged from 78.2% to 83.9%, CONCLUSION: Agreement between diagnoses of dermatological diseases reached following examination of digital images and those reached following live examination of the patient was excellent.

FUNDAMENTOS: A teledermatologia, pouco utilizada no Brasil e com iniciativas incipientes no Amazonas, necessita de estudos para demonstrar sua factibilidade e eficácia. OBJETIVOS: Avaliar a eficácia de um método assíncrono de teledermatologia, utilizando recursos tecnológicos simples e de baixo custo. MÉTODOS: Cento e setenta e quatro pacientes foram examinados por quatro dermatologistas; dois efetuaram diagnóstico presencial (A1 e A2) e dois por meio de imagens das lesões e história clínica (B1 e B2). Foi investigada a concordância entre as avaliações presenciais e por imagens. RESULTADOS: A concordância do diagnóstico principal entre os examinadores presenciais (A1 e A2) foi de 83,3 por cento e entre os de imagens (B1 e B2), de 81 por cento. A concordância entre o diagnóstico principal estabelecido pelo método presencial e o obtido por meio de imagens variou de 78,2 por cento a 83,9 por cento. CONCLUSÃO: O diagnóstico de doenças dermatológicas realizado por imagens digitais demonstrou concordância ótima quando comparado àquele realizado com a presença física do paciente.

Purpose: To verify the presence of M. leprae in the periodontium, saliva and skin slit smears of leprosy patients. To correlate bacteriological and molecular findings with clinical data and compare laboratory techniques. Methods: A cross-sectional study was designed to use bacteriological (baciloscopy) and molecular (PCR) parameters to detect M. leprae in exudates of the gingival sulcus/periodontium pocket, saliva and skin slit smears from multiple clinical forms of leprosy patients without previous treatment. Results: The study included 48 leprosy patients with 15 multibacillary (MB) cases and 33 paucibacillary (PB) cases. The diagnosis of MB was confirmed through bacteriological examination and PCR results from skin slit smears. A total of 16 (48.5%) PB patients were PCR positive only. Four PB patients with negative PCR skin smears were PCR positive for the periodontium and saliva, with 2 cases and 1 case, respectively. No periodontium or saliva samples had positive bacteriological results. Conclusion: There was no correlation between periodontal disease and the presence of M. leprae. Bacteriological examination did not prove to be an efficient technique for the analysis of saliva and periodontium samples. PCR analysis of skin smears was more efficient at diagnosing PB patients than bacteriological examination. PCR positive results for the detection of M. leprae in PB patients can be increased by collecting slit skin smears, periodontium and saliva samples.
Objetivo: verificar através da baciloscopia e da reação em cadeia da polimerase (PCR) a presença do M. leprae no periodonto, saliva e raspados intradérmicos de pacientes com hanseníase. Metodologia: Realizou-se um estudo transversal do tipo detecção de casos numa instituição referência de hanseníase no Amazonas. Resultados: Foram avaliados 48 pacientes, sendo 15 multibacilares (MB) e 33 paucibacilares (PB). Os pacientes MB tiveram o diagnóstico confirmado pela baciloscopia e PCR dos raspados intradérmicos, enquanto que 16 (48,5%) dos PB foram positivos apenas na PCR. Quatro pacientes PB negativos na PCR de raspados intradérmicos foram positivos no periodonto e na saliva, 1 positivo na saliva e 2 no periodonto. Nenhuma amostra do periodonto e da saliva foi positiva na baciloscopia. Conclusão: Não houve relação entre a doença periodontal e a presença do M. leprae; a baciloscopia não mostrou ser uma técnica eficiente para análise da saliva e periodonto; a técnica de PCR de raspado dérmico mostrou ser um método mais eficaz no diagnóstico dos PB do que a baciloscopia; a positividade da PCR para detecção do M. leprae nos PB pode ser aumentada coletando raspado intradérmico, periodonto e saliva.

OBJETIVO: Analisar a epidemiologia de hanseníase segundo a distribuição espacial e condições de vida da população. MÉTODOS: Estudo ecológico baseado na espacialização da hanseníase em Manaus (AM), entre 1998 e 2004. Os 4.104 casos obtidos do Sistema de Informações de Agravos de Notificação foram georreferenciados de acordo com a localização dos endereços em 1.536 setores censitários urbanos, por meio de quatro técnicas: correios (73,7 por cento dos endereços encontrados); Programa de Cadastro de Logradouros (7,3 por cento); Programa Saúde da Família (2,1 por cento) e folhas de coleta do Instituto Brasileiro de Geografia e Estatística (1,5 por cento). Para cálculo do coeficiente de detecção utilizou a população de 2001. Na análise espacial foi aplicado o método bayesiano empírico local para produzir uma estimativa do risco da hanseníase, suavizando o efeito da flutuação das taxas, quando calculadas para pequenas áreas. Para análise da associação entre espacialização e fatores de risco empregou-se a regressão logística, tendo como variáveis explicativas a ocorrência de casos em menores de 15 anos (indicador de gravidade) e o Índice de Carência Social construído a partir das variáveis do Censo 2000. RESULTADOS: O coeficiente de detecção apresentou-se hiperendêmico em 34,0 por cento dos setores e muito alto em 26,7 por cento. A medida de associação (odds ratio) referente às variáveis explicativas foi significativa. A combinação de baixa condição de vida e ocorrência em menores de 15 anos foi adotada para identificar as áreas prioritárias para intervenção. CONCLUSÕES: A análise espacial da hanseníase mostrou que a distribuição da doença é heterogênea, atingindo mais intensamente as regiões habitadas por grupos em situação de maior vulnerabilidade.

OBJECTIVE: To analyze the epidemiology of leprosy according to spatial distribution and living conditions of the population. METHODS: Ecological study based on the spatial distribution of leprosy in the municipality of Manaus, Northern Brazil, from 1998 to 2004. The 4,104 cases identified in the Sistema de Informações de Agravos de Notificação (Sinan -National Notification System) were georeferenced according to the addresses in the 1,536 urban census tracts through four different sources: postal service (73.7% of addresses found), Property Registration Program (7.3%), Family Health Program (2.1%), and Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics) data sheet (1.5%). Calculation of detection coefficient was performed based on the 2001 population. Local empirical Bayesian method was used for the spatial distribution analysis, in order to estimate leprosy risk, making rate variation shorter when they were calculated for small areas. Logistic regression was employed to analyze the association between geographical distribution and risk factors. The incidence of cases in children under 15 (severity indicator) and Social Need Index built from variables of the 2000 census were adopted as explicative variables. RESULTS: The mean coefficient of detection was hyperendemic in 34.0% of the census tracts, and very high in 26.7%. Odds ratio was obtained for explicative variables and proved to be significant. Low-income and incidence in children under 15 were combined to identify priority areas for intervention. CONCLUSIONS: Spatial analysis of leprosy showed that the distribution of the disease is heterogeneous and is more strongly present in regions inhabited by more vulnerable groups.

O presente estudo teve como objetivo analisar, por meio do exame neurofuncional, a eficácia da cirurgia de neurólise em pacientes com neurite hansênica. Tratou-se de um estudo prospectivo, do tipo descritivo. Teve como universo de estudo a população portadora de neurite hansênica do Estado do Amazonas, tratada na FUAM-AM. Foram selecionados 27 participantes os quais foram triados para cirurgia eletiva de neurólise no período de outubro de 2004 a janeiro de 2005, correspondendo a 64 cirurgias eletivas. Foi realizada uma avaliação neurofuncional pré-operatória compreendendo o teste de força muscular manual, teste de sensibilidade pelos estesiômetros de Semmes-Weinstein, avaliação da dor por meio de escala analógica visual e classificação do grau de incapacidade.A mesma avaliação foi repetida um mês após a cirurgia. Os principais nervos operados foram, em ordem decrescente, medial e ulnar, fibular comum e tibial posterior. A forma clínica mais comum entre os mesmos foi a virchowiana (67 por cento), seguida da dimorfa-virchoviana (19 por cento), tuberculóide (7 por cento) e dimorfa-tuberculóide (7 por cento). Setenta e quatro por cento dos pacientes operados encontravam-se em alta clínica e 26 por cento ainda realizavam tratamento por poliquimioterapia. A principal queixa apresentada foi dor (55 por cento). Em relação ao grau de incapacidade, 70 por cento apresentaram grau I e 30 por cento apresentaram grau II. No pós-operatório, foi relatada melhora da dor em 64 por cento das cirurgias, 30 por cento não apresentaram alteração e 6 por cento apresentaram piora. Cinqüenta e seis por cento dos nervos com comprometimento motor não apresentaram melhora, 32 por cento melhoraram em até um grau e 12 por cento apresentaram piora em até um grau. Trinta e quatro por cento dos pacientes apresentaram melhora da sensibilidade, e 66 por cento se mostraram com quadro inalterado.
The aim of this study was to analyze, through neurofunctional assessment, the effectiveness of the neurolysis surgery in patients with neuritis due to leprosy. It was a prospective and descriptive study. The subjects of this study were the population with neuritis due to leprosy of Amazon state, treated in Fundação Alfredo da Matta (FUAM-AM). 27 participants were selected for elective surgery of neurolysis from October 2004 to January 2005, corresponding to 64 elective surgeries. A preoperative neurofunctional assessment was carried out including manual muscle strength testing, sensibility test using Semmes-Weinstein nylon filaments, pain assessment using a visual analogical scale and classification of rate disability. The same assessment was repeated one month after surgery. The main nerves that underwent surgery were, in decreasing order, medial and ulnar, fibular and posterior tibial. The clinical form more frequently was the lepromatous form (67 percent), following by the lepromatous-borderline (19 percent), tuberculoid (7 percent) and tuberculoid-borderline (7 percent). Seventy four percent of patients had already finished clinical treatment and 26 percent were still using multidrug therapy. Fifty five percent referred pain complaint. Concerning rate disability, 70 percent had level I and 30 percent level II. During the postoperative, patients referred to get better pain sensation in 64 percent of surgeries, 30 percent did not have alteration and 6 percent were worst. Fifty six percent of motor nerves degeneration did not improve, 32 percent improved one level and 12 percent have become worse one level. Thirty four percent of patients referred improvement of sensibility and 66 percent referred no improvement.

OBJETIVO: Analisar a situação epidemiológica da hanseníase em crianças, em zona urbana. MÉTODOS: Foram estudados 474 casos de hanseníase, em menores de 15 anos, detectados na zona urbana de Manaus (AM), de 1998 a 2005. A partir dos dados do Sistema de Informações de Agravos de Notificação foram analisados o perfil da endemia e a qualidade do atendimento nos serviços de saúde, utilizando os indicadores epidemiológicos e operacionais Programa Nacional de Eliminação da Hanseníase. RESULTADOS: Os casos de hanseníase em menores de 15 anos corresponderam a 10,4 por cento do total de casos detectados no período. O coeficiente de detecção nessa faixa etária manteve-se no nível hiperendêmico entre 1998 e 2003, reduzindo a partir do ano de 2004 mas mantendo endemicidade muito alta. A forma clínica mais freqüente foi a tuberculóide, seguida da dimorfa. As formas paucibacilares corresponderam a 70,7 por cento dos casos e no momento do diagnóstico, o grau de incapacidades foi avaliado em 94,7 por cento dos pacientes, dos quais 2,9 por cento apresentaram incapacidades físicas. A maioria dos casos (99,4 por cento) foi tratada com o esquema poliquimioterápico da Organização Mundial da Saúde. CONCLUSÕES: Apesar de seu decréscimo, o coeficiente de detecção da hanseníase nas crianças em Manaus mantém nível de endemicidade muito alto.

OBJECTIVE: To describe the epidemiological status of leprosy in children living in a metropolitan area. METHODS: There were studied 474 leprosy cases detected in children under 15 living in the metropolitan area of the city of Manaus, Northern Brazil, between 1998 and 2005. The endemic profile and quality of care services were assessed based on data from the Notifiable Diseases Information System using epidemiological and operational indicators of the National Leprosy Elimination Program. RESULTS: Of all leprosy cases detected in the period studied, 10.4% were found in children under 15. The detection rates in this age group remained at hyperendemic levels between 1998 and 2003, and decreased from 2004 onwards but keeping on very high endemic levels. The most common clinical form was tuberculoid followed by dimorphous. Paucibacillary forms were seen in 70.7% of the cases. The level of disability at the time of diagnosis was assessed in 94.7% of patients and 2.9% of them had physical disabilities. Most children (99.4%) were treated with the multiple drug regimen recommended by the World Health Organization. CONCLUSIONS: Despite its decrease, detection rate of leprosy in children in the city of Manaus remains at a very high endemic level.
