ABSTRACT

Ankle osteoarthritis (AOA) is associated with pain and variable functional limitation, demanding clinical treatment and possible surgical indication when conservative measures are ineffective - arthrodesis has been the procedure of choice, because it reduces pain, restores joint alignment and makes the segment stable, preserving gait. The present study reports 3 cases (3 ankles) of male patients between 49 and 63 years old, with secondary AOA, preoperative American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS AHS) of 27 to 39 points, treated by minimally invasive tibiotalocalcaneal arthrodesis using blocked retrograde intramedullary nail. Hospital stay was of 1 day, and the patients were authorized for immediate loading with removable ambulation orthotics, as tolerated. The physical therapy treatment, introduced since hospitalization, was maintained, prioritizing gait training, strength gain, and proprioception. Clinical and radiographic follow-up was performed at weeks 1, 2, 6, 12 and 24. After evidence of consolidation (between the 6 th and 10 th weeks), the orthotics were removed. One patient complained of pain in the immediate postoperative period and, at the end of the 1 st year, only one patient presented pain during rehabilitation, which was completely resolved with analgesics. Currently, the patients do not present complaints, returning to activities without restrictions - one of them, to the practice of soccer and rappelling. The postoperative AOFAS AHS was from 68 to 86 points.

Resumo A osteoartrite do tornozelo (OAT) está associada a quadro álgico e limitação funcional variável, demandando tratamento clínico e eventual indicação cirúrgica quando as medidas conservadoras são inefetivas - a artrodese tem sido o procedimento de escolha, por reduzir a dor, restaurar o alinhamento articular e tornar o segmento estável, preservando a marcha. O presente estudo relata 3 casos (3 tornozelos) de pacientes do sexo masculino, com entre 49 e 63 anos de idade, portadores de OAT secundária, American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS AHS, na sigla em inglês) pré-operatória de 27 a 39 pontos, tratados mediante artrodese tibiotalocalcaneana minimamente invasiva utilizando haste intramedular retrógrada bloqueada. A permanência hospitalar foi de 1 dia, e os pacientes foram autorizados para carga imediata com órteses removíveis para deambulação, conforme tolerado. O tratamento fisioterápico, introduzido desde o internamento, foi mantido, priorizando-se treino de marcha, ganho de força e propriocepção. Foi realizado acompanhamento clínico e radiográfico nas semanas 1, 2, 6, 12 e 24. Após evidências de consolidação (entre a 6ª e a 10ª semanas), as órteses foram retiradas. Um paciente queixou-se de dor no pós-operatório imediato e, ao final do 1° ano, apenas 1 paciente apresentou dor durante a reabilitação, resolvida completamente com analgésicos. Atualmente, os pacientes não apresentam queixas, retornando às atividades sem restrições - um deles, à prática de futebol e rapel. A AOFAS AHS pós-operatória foi de 68 a 86 pontos.

ABSTRACT

The worldwide loudspeaker market follows the growing tendency of electronic entertainment technologies both in quantity and variety. Consequently, the environmental impacts caused during the life cycle of loudspeakers increase in the same proportion, going in the opposite direction to what is determined by world environmental laws and regulations and global market tendencies. Even so, the environmental performance of this type of product is not considered in the decision-making process for technological updates in loudspeaker design. In this sense, Ecodesign is the most adequate Life Cycle Engineering tool applied in the design of a product since the environmental performance is considered throughout the different design stages. However, the feasibility of Ecodesign in products requiring complex production chains relies on splitting the product into subsystems and components. Thus, the present work focuses on evaluating the environmental performance of a classic loudspeaker motor, which is composed of a magnet, coil, and coil former. Eight raw material substitution scenarios are proposed and analyzed, which allowed the proposal identification with the best environmental performance within the current technologies. This represents an initial step toward the complete Ecodesign of a loudspeaker and sets the procedure to be followed with the other constitutive parts.

ABSTRACT

Introduction: Airborne fungi can cause respiratory diseases, including pulmonary mycoses. The objective of this study was to isolate and identify airborne fungi from external and internal environments at a full-day primary school in Manaus, Brazil, and ascertain the influence of seasonality on the incidence of these microorganisms. Methods: Airborne fungi were collected by exposing Sabouraud agar plates at various external and internal locations in the school. Results: A total of 2,386 fungal colonies were isolated, 1,041 in the rainy season and 1,345 during the dry season. Of these, 1,858 were identified and distributed into 34 genera. The most prevalent were Cladosporium sp. (22.6%); Aspergillus sp. (17.14%); Penicillium sp. (8.55%); Curvularia sp. (6.83%); and Drechslera sp. (5.7%). During the dry season, the most prevalent genre was Aspergillus (19.3%), while in the rainy season, Cladosporium predominated (34.6%). Conclusion: Seasonality influenced fungal incidence, especially of the genus Cladosporium, which increased significantly during the rainy season. Cladosporium can be considered a bioindicator of the rainy season in the Brazilian Amazon.


Introdução: Os fungos presentes no ar, denominados anemófilos, possuem uma ampla diversidade em locais de clima tropical e são causadores de micoses pulmonares e outras doenças do aparelho respiratório. O objetivo do estudo foi isolar e identificar os fungos do ar de uma escola de ensino fundamental de tempo integral, a partir de ambientes externos e internos, e verificar se a sazonalidade influencia a incidência desses microrganismos. Métodos: Para coleta dos fungos do ar, placas de Petri contendo Sabouraud foram expostas nos ambientes externos e internos da escola. Resultados: Foram isoladas 2.386 colônias de fungos, sendo 1.041 na estação chuvosa e 1.345 na estação seca. Foram identificados 1.858 fungos, que puderam ser distribuídos em 34 gêneros. Os gêneros mais frequentes foram Cladosporium sp. (22,6%), Aspergillus sp. (17,14%), Penicillium sp. (8,55%), Curvularia sp. (6,83%) e Drechslera sp. (5,7%). Durante o período seco, o gênero mais frequente foi o Aspergillus (19,21%), e no período chuvoso, o gênero Cladosporium (34,8%). Conclusão: A sazonalidade influenciou principalmente o gênero Cladosporium, que obteve aumento significativo na estação chuvosa, constituindo um biomarcador dessa estação.

ABSTRACT

Antecedentes. Apenas se dispone de estudios científicos que hayan investigado las dermatofitosis en niños que viven en el estado de Amazonas o en la región más septentrional de Brasil. Objetivos. El objetivo de este estudio fue investigar la frecuencia y la etiología de las dermatofitosis en niños de 12 años de edad o menores, que fueron examinados entre marzo de 1996 y noviembre de 2005 en el Laboratorio de Micología del Instituto Nacional de Investigaciones de Amazonia. Métodos. Para el diagnóstico micológico, se utilizaron muestras de escamas epidérmicas y/o cabello. Una parte de la muestra se trasladó a un portaobjetos y se añadió una solución de hidróxido de potasio para examen microscópico directo. La otra parte de la muestra se sembró en medio de cultivo (Mycobiotic Agar) para el aislamiento de los dermatofitos. Resultados. De las 590 muestras analizadas, en 210 se aislaron dermatofitos mediante examen microscópico directo y cultivo. La tiña del cuero cabelludo (153 casos) fue la dermatofitosis más frecuente, y Trichophyton tonsurans (121 casos) fue el patógeno aislado más habitual. En 48 casos se detectó tiña corporal, siendo también T. tonsurans el hongo aislado más frecuente (17 casos), y las regiones corporales más afectadas fueron la cara, extremidades superiores y tronco. El laboratorio confirmó un pie de atleta en 6 casos y los principales hongos aislados fueron Trichophyton rubrum (3) y Trichophyton mentagrophytes (3). La tiña crural solo se confirmó en 3 casos, en los que se aislaron T. rubrum, T. tonsurans y Epidermophyton floccosum. Conclusiones. En los niños examinados, la tiña del cuero cabelludo fue la afectación principal y el patógeno responsable de estas dermatofitosis fue T. tonsurans(AU)


Background. Few scientific studies have evaluated dermatophytosis among children in the state of Amazonas or in the greater northern region of Brazil. Aims. The aim of this study was to research the frequency and aetiology of dermatophytosis in children age 12 and under, who were seen between March 1996 and November 2005 at the Mycology Laboratory of the National Institute of Amazonian Research. Methods. For mycological diagnoses, epidermal scales and/or hairs were used. A portion of this material was treated with potassium hydroxide for direct examination, and another portion was cultivated in Mycobiotic Agar for the isolation of dermatophytes. Results. Of the 590 samples analysed, 210 showed positive diagnoses by direct examination and cultivation. Tinea capitis (153 cases) was the most frequent type of dermatophytosis, and Trichophyton tonsurans (121 cases) was the most frequently isolated fungal agent. Tinea corporis was observed in 48 cases where the most frequently isolated fungal agent was also T. tonsurans (17 cases), and the corporal regions most affected were the face, arms and trunk. The laboratory confirmed tinea pedis in 6 cases, and the principal fungal agents isolated were Trichophyton rubrum (3) and Trichophyton mentagrophytes (3). The presence of tinea cruris was confirmed in 3 cases, and T. rubrum, T. tonsurans and Epidermophyton floccosum were isolated from these cases. Conclusions. The children examined were primarily affected by tinea capitis, and the main fungal agent for this dermatophytosis was T. tonsurans(AU)

ABSTRACT

Neste trabalho, relata-se um caso de miíase oral onde será discutida a importância da identificação entomológica e a necessidade de rigorosa vigilância sanitária nos hospitais. Semelhantemente a outros tipos de infestações em áreas endêmicas, as condições epidemiológicas descritas podem indicar que a real prevalência de miíase humana em hospitais pode ser mais alta do que tem sido publicada.


This paper describes a case of oral myiasis and discusses the importance of entomological identification, as well as the need for strict health surveillance in hospitals. Similarly to other types of infestations in endemic areas, the epidemiological conditions described here suggest that the actual prevalence of human myiasis in hospitals may be higher than what has been published.

ABSTRACT

FUNDAMENTOS: Micoses superficiais estritas são infecções fúngicas que se localizam nas camadas superficiais da pele e seus anexos. As micoses superficiais cutâneas representadas pelas dermatofitoses e candidíases podem ultrapassar a camada córnea da pele. Na região amazônica possuem incidência elevada. OBJETIVOS: Estudar as micoses superficiais, estritas e cutâneas, diagnosticadas sob o ponto de vista epidemiológico e micológico. PACIENTES E MÉTODOS: Pacientes com suspeita clínica de micoses superficiais submetidos a exame micológico no período de março a novembro de 2003 no Laboratório de Micologia Médica/CPCS/INPA. RESULTADOS: Foram realizados 394 exames, tendo 256 apresentado diagnóstico positivo. As micoses mais incidentes foram onicomicoses (135) e pitiríase versicolor (98). Malassezia spp. (77) e Candida spp. (72) foram os agentes fúngicos mais isolados. Tinea capitis apresentou maior ocorrência nos pré-escolares (3), e onicomicoses em adultos (94). O sexo feminino foi o mais acometido (91). Todas as classes sociais foram infectadas, com predominância da C (37). CONCLUSÃO: Onicomicoses e pitiríase versicolor acometeram sobretudo adultos. A Tinea capitis ocorre principalmente, em crianças. As micoses superficiais apresentaram mais incidentes nas mulheres. Malassezia spp. e Candida spp. foram os agentes mais isolados.

ABSTRACT

O propósito desta investigaçäo foi determinar se a administraçäo pré-operatória de um agente ansiolítico oral (Diazepam) e injeçöes intraorais de Bupivacaina (Neocaina 0,5 per cent sem epinefrina) säo benéficas na reduçäo das respostas cardiovasculares ao estresse e à ansiedade. Dez pacientes hipertensos que receberam a droga, e outro dez, também hipertensos, que receberam o placebo, foram monitorados pré-operatoriamente e durante uma cirurgia menor. Níveis de ansiedade, assim como parâmetros cardiovasculares foram determinados para os dois grupos. Os resultados deste trabalho sugerem que injeçöes de Bupivacaína (Neocaína 0,5 por cento sem epinefrina), associadas à premedicaçäo Diazepam, atenuam a ansiedade e diminuem as respostas cardiovasculares

ABSTRACT

Ratos machos foram submetidos à hipervitaminose A por injeções intraperitoneais diárias de 150 UI de Arovit por grama de peso corporal. Outros animais, nas mesmas condições anteriores, servindo de controles, receberam injeções de solução salina, durante 10 dias. Nos animais tratados com excesso de vitamina A observou-se significante perda de peso. Histologicamente, no epitélio do esôfago observou-se um aumento na espessura epitelial, caracterizando um quadro de hiperplasia e hipertrofia. Os resultados obtidos nessa pesquisa sugerem a possibilidade de o excesso de vitamina A atuar no epitélio do esôfago diretamente sobre as estruturas epiteliais, estimulando um aumento das mitoses, e no epitélio (mediada pela adrenal), acarretando aumento de espessura pela concentração de um número maior de células imaturas, além da presença de células mais volumosas. Tais alterações foram mais evidentes no terço inferior do esôfago
