Abstract Studies investigating the effects of different modalities of exercises on the immune system are scarce. Therefore, the aim of this study was to compare the effects of eight weeks of resistance and aerobic training on the proliferation of T and B lymphocytes from mice. Eighteen male C56BL6/J mice were divided into groups (n=6), sedentary, aerobic, and resistance training. After 8 weeks, animals were euthanized, and their splenocytes were labeled and cultured with and without stimulation. Lymphocyte proliferation (CD4+, CD8+ and CD21/CD35+) was evaluated by flow cytometry. The mice subjected to resistance exercise exhibited greater proliferation for total, CD8+ and B lymphocytes (p<0.05), but not CD4+ cells (p>0.05), compared with their sedentary counterparts. We found significant correlations between maximum load and total, CD8+ and B lymphocytes proliferation rates (p<0.05). In conclusion, our results showed that resistance training promoted an improvement in the immune response associated with CD8+ and B lymphocytes.

Abstract The genus Candida represents the main cause of infections of fungal origin. Some species stand out as disease promoters in humans, such as C. albicans, C. glabrata, C. parapsilosis, and C. tropicalis. This study evaluated the antifungal effects of propyl (E)-3-(furan-2-yl) acrylate. The minimum inhibitory concentration of the synthetic compound, amphotericin B and fluconazole alone against four species of Candida ranged from 64 to 512 μg/mL, 1 to 2 μg/mL, and 32 to 256 μg/mL, respectively. The synergistic effect of the test substance was observed when associated with fluconazole against C. glabrata, there was no antagonism between the substances against any of the tested strains. The potential drug promoted morphological changes in C. albicans, decreasing the amount of resistance, virulence, and reproduction structures, such as the formation of pseudohyphae, blastoconidia, and chlamydospores, ensuring the antifungal potential of this substance. It was also possible to identify the fungicidal profile of the test substance through the study of the growth kinetics of C. albicans. Finally, it was observed that the test compound inhibited the ergosterol biosynthesis by yeast.

Resumen Introducción. Giardia duodenalis es un protozoo intestinal de gran prevalencia en los niños de los países en desarrollo. En estudios moleculares se ha evidenciado la gran diversidad genética de G. duodenalis y se han identificado los conjuntos A y B, principalmente en humanos. A pesar de su importancia, el conocimiento de la epidemiología molecular de la giardiasis humana aún es limitado en Brasil. Objetivo. Caracterizar los aislamientos moleculares de G. duodenalis de muestras tomadas a niños de Salvador, Bahía, Brasil. Materiales y métodos. Las muestras fecales positivas para G. duodenalis se obtuvieron de 71 niños de dos guarderías y de 39 usuarios de un laboratorio de análisis clínicos. Las muestras se analizaron mediante PCR-RFLP de los genes gdh y beta-giardin, y secuenciación de beta-giardin. Resultados. De las 110 muestras de G. duodenalis, en 80 (72,7 %) se amplificaron uno o ambos genes. De estos, 62 (77,5 %) se identificaron como pertenecientes al conjunto A y 18 (22,5 %) al B. El subconjunto AII se identificó en el 58,8 % (n=47) de los aislamientos, seguido del AI en el 18,8% (n=15), el BIV en el 11,2% (n=9) y el BIII en el 5,0% (n=4). El subconjunto AII fue el más frecuente en los niños de ambas guarderías, en tanto que el AI solo se encontró en el grupo atendido en el laboratorio clínico. El subconjunto AII predominó en los niños menores de dos años. Conclusiones. La mayor frecuencia del subconjunto AII sugiere que la transmisión antroponótica es más común en Salvador, pero también existen vías de transmisión zoonóticas, y que pueden ocurrir cambios en la sensibilidad frente a diferentes patrones moleculares de Giardia durante el crecimiento infantil.

Abstract Introduction. Giardia duodenalis is an intestinal protozoan with a high prevalence in children of developing countries. Molecular studies revealed a great genetic diversity of G. duodenalis, with assemblages A and B found mainly in humans. Despite its importance, the information on the molecular epidemiology of human giardiasis is still limited in Brazil. Objective. To characterize G. duodenalis molecular isolates in children from Salvador, Bahia, Brazil. Materials and methods. Giardia duodenalis positive fecal samples were obtained from 71 children from two day care centers and 39 users of a clinical analysis laboratory. Samples were analyzed by PCR-RFLP of the glutamate dehydrogenase (gdh) and beta-giardin genes and by the sequencing of beta-giardin. Results. Of the 110 G. duodenalis samples, 80 (72.7%) amplified one or both target genes. Of these, 62 (77.5 %) were identified as assemblage A and 18 (22.5%) as assemblage B. The subassemblage AII was identified in 58.8% (n=47) of isolates followed by the sub-assemblage AI (18.8%, n=15), BIV (11.2%, n=9), and BIII (5.0%, n=4). The AII sub-assemblage was the most frequent in children of both day care centers whereas AI was found only in the group attended at the clinical laboratory. Sub-assemblage AII predominated in children under two years. Conclusions. The higher frequency of AII sub-assemblage suggests that anthroponotic transmission is more common in Salvador, but that zoonotic transmission pathways are also present and a change in susceptibility to different molecular patterns of Giardia may occur during child growth.

Abstract Streptococcus agalactiae is one of the most common pathogens leading to mastitis in dairy herds worldwide; consequently, the pathogen causes major economic losses for affected farmers. In this study, multilocus sequence typing (MLST), genotypic capsular typing by multiplex polymerase chain reaction (PCR), and virulence gene detection were performed to address the molecular epidemiology of 59 bovine (mastitis) S. agalactiae isolates from 36 dairy farms located in the largest milk-producing mesoregions in Brazil (Minas Gerais, São Paulo, Paraná, and Pernambuco). We screened for the virulence genes bac, bca, bibA, cfb, hylB, fbsA, fbsB, PI-1, PI-2a, and PI-2b, which are associated with adhesion, invasion, tissue damage, and/or immune evasion. Furthermore, five capsular types were identified (Ia, Ib, II, III, and IV), and a few isolates were classified as non-typeable (NT). MLST revealed the following eight sequence types (STs): ST-61, ST-67, ST-103, ST-146, ST-226, ST-314, and ST-570, which were clustered in five clonal complexes (CC64, CC67, CC103, CC17, and CC314), and one singleton, ST-91. Among the virulence genes screened in this study, PI-2b, fbsB, cfb, and hylB appear to be the most important during mastitis development in cattle. Collectively, these results establish the molecular epidemiology of S. agalactiae isolated from cows in Brazilian herds. We believe that the data presented here provide a foundation for future research aimed at developing and implementing new preventative and treatment options for mastitis caused by S. agalactiae.

Resumo Introdução: Doenças de notificação compulsória (DNC) abrangem quadros de alta gravidade clínica e/ou de contágio. Sendo comunidades fechadas, instituições de longa permanência para idosos (ILPI) são locais que merecem atenção quanto a elas. Mas qual seria a realidade das DNC em ILPI brasileiras? Objetivo: Determinar prevalência e tipo de DNC em ILPI de grande porte. Método: Busca ativa de DNC pela Comissão de Controle de Infecção Hospitalar (CCIH) em 459 leitos. Em razão da baixa rotatividade de pacientes, analisou-se lista mensal da CCIH sobre DNC. Dividiram-se os dados entre homens e mulheres e entre idosos (idade ≥ 60 anos) e não idosos (idade ≤ 59 anos). Resultados: 31 doenças em 29 pacientes (6,9% do total de internados - 19 homens e 10 mulheres): 23 casos de hepatite C, cinco de hepatite B, dois de positividade sorológica ao vírus da imunodeficiência humana (HIV) e um caso de tuberculose renal. Um paciente com hepatite B e outro com HIV positivo eram também portadores de hepatite C. Não houve significância estatística quando foram comparados os dois grupos com o total dos outros internados - por idade e gênero - pelo total de DNC e nos casos de hepatite C (p>0,05). Conclusão: Pesquisa em 15/11/2008 no portal http://www.scielo.br/não detectou casuísticas em ILPI, exceto por revisões sobre tuberculose. DNC de caráter e/ou tratamento crônico observadas neste estudo sugerem a necessidade de maior número de publicações para definir a dinâmica dessas doenças em ILPI brasileiras.

Summary Introduction: Notifiable diseases (NDs) encompass conditions of high clinical severity and/or contagious. Being closed communities, long-term care facilities (LTCF) are places that deserve attention on their own, but one might be left wondering: what is the reality of NDs at Brazilian LTCFs? Objective: To determine the prevalence and type of NDs at large LTCF. Method: Active search for NDs conducted by the Hospital Infection Control Committee (HICC) in 459 beds. Due to the low turnover of patients, the monthly list kept by the HICC on NDs was analyzed. Data were grouped into males and females, and into elderly (age ≥ 60 years) and non-elderly (age ≤ 59 years). Results: 31 diseases in 29 patients (6.9% of all inpatients - 19 males and 10 females): 23 cases of hepatitis C, five of hepatitis B, two of human immunodeficiency virus (HIV), and one case of renal tuberculosis. One patient with hepatitis B and another HIV-positive also had hepatitis C. There was no statistical significance in the comparison of the two groups with the total number of other institutionalized patients - by age and gender - for total number of NDs and cases of hepatitis C (p>0.05). Conclusion: Chronic NDs and those requiring chronic treatment observed in this study suggest that Brazil needs more studies to define the dynamics of these diseases at LTCFs.

RESUMO CONTEXTO E OBJETIVO: Busca nos portais SciELO e PubMed encontrou poucos estudos sobre indivíduos positivos para o vírus da imunodeficiência humana (HIV) em instituições de longa permanência para idosos (ILPIs), fato este que justifica o presente estudo. O objetivo foi verificar se há soropositivos para o HIV em instituições de ILPIs. TIPO DE ESTUDO E LOCAL: Estudo transversal por consulta à Comissão de Controle de Infecção Hospitalar (CCIH) de ILPI com 405 leitos. MÉTODOS: Solicitaram-se 405 prontuários de pacientes internados, nos quais se pesquisou sorologia reagente ao HIV para análise de: [1] idade e gênero; [2] período de internação na ILPI (meses); [3] causa(s) e diagnósticos à internação na ILPI pela Classificação Internacional de Doenças, 10a edição; [4] data do diagnóstico do HIV; [5] soropositividade para sífilis e vírus da hepatite B e C; [6] medicamentos em uso na última prescrição no prontuário; e [7] média de linfócitos CD4 baseada em: número total de linfócitos/6 e número total de linfócitos x 0,8 x 0,2 ou 0,3. RESULTADOS: Quatro homens eram HIV-positivos. Eles tinham 71,2 ± 8,6 anos de idade; 74,2 ± 38,1 meses na ILPI e 24,5 ± 17 meses de soropositividade (diagnósticos realizados como triagem padrão da CCIH). Havia sequelas de acidente vascular cerebral em 3 e síndrome demencial em 1; sorologias positivas para sífilis em 2, vírus hepatite B em 2 e C em 1. Os principais fármacos utilizados eram: lamivudina, zidovudina, lopinavir, ritonavir, levotiroxina, omeprazol, ranitidina, lactulona e risperidona. O CD4 foi estimado em 341 ± 237/mm3. CONCLUSÕES: Há soropositivos para o HIV em ILPIs, passíveis de diagnóstico em triagens sorológicas e de tratamento com antirretrovirais.

ABSTRACT CONTEXT AND OBJECTIVE: A search in the SciELO and PubMed databases showed few studies on human immunodeficiency virus (HIV) positive individuals in long-term care institutions (LTCIs), thus prompting the present study. The aim of this study was to ascertain whether there were any HIV-positive individuals in LTCIs for the elderly. DESIGN AND SETTING: Cross-sectional study in which the Hospital Infection Control Committee (HICC) of a 405-bed LTCI was consulted. METHODS: The medical records of 405 individuals interned in the LTCI who had been tested for HIV infection were requested for analysis of the following variables: [1] age and gender; [2] length of stay at LTCI (months); [3] causes and diagnoses on admission to LTCI according to International Classification of Diseases, 10th edition; [4] date of HIV diagnosis; [5] seropositivity for syphilis and hepatitis B and C viruses; [6] medications used at last prescription in medical file; and [7] mean CD4 lymphocyte count based on: total lymphocyte count/6 and total lymphocyte count x 0.8 x 0.2 or 0.3. RESULTS: Four men were HIV-positive, with mean age 71.2 ± 8.6 years, LTCI stay 74.2 ± 38.1 months and length of HIV diagnosis 24.5 ± 17 months (confirmed by HICC standard screening). Three had stroke sequelae; one, dementia syndrome; two, seropositivity for syphilis; two, hepatitis B and one, hepatitis C. The main drugs used were lamivudine, zidovudine, lopinavir, ritonavir, levothyroxine, omeprazole, ranitidine, lactulose and risperidone. The estimated CD4 count was 341 ± 237/mm3. CONCLUSIONS: HIV-positive individuals are present in LTCIs, diagnosable through serological screening and treatable with antiretroviral drugs.

Inorganic compounds doped with rare earths (Ce3+, Pr3+, Nd3+, Sm3+, Eu 3+, Gd 3+, Tb 3+, Tm3+) have been used in various applications including light-emitting devices such as fluorescent lamps, cathode ray tubes, lasers and inorganic pigments. In this study, Pr3+ is doped in spinel Li2ZnTi3O8 system and synthesized by the polymeric precursor method, which is based on the process developed by the Pechini, and characterized by X-ray diffraction, UV-visible and CIE-L colorimetric measures * a * b *., in order to study the effect of doping and thermal treatment on its colorimetric properties. With three different samples of Pr3+ doping (0.01; 0.05 and 0.1 mol%) were prepared and calcined at 500°C, 600°C, 700°C, 800°C and 900°C for 4 h. The analysis of X-ray diffraction confirmed the formation of pure phases with spinel structure and average crystallite size of less than 46 nm. It was found that the colorimetric properties ranging from green to red, in accordance with the increase in the concentration of Pr3+ and thermal processing temperature.

OBJETIVOS: A inaloterapia representa a principal forma de tratamento da asma e seu uso adequado tem sido fator responsável pelo controle da doença. Desse modo, o objetivo do estudo foi determinar se uma ferramenta de mídia digital, dotada de portabilidade na forma de telefonia móvel, modifica a assimilação da técnica inalatória. MÉTODOS: Foram selecionados 66 profissionais que atuam na área da saúde com população pediátrica e submetidos a um pré-teste sobre seus conhecimentos de inaloterapia. Os profissionais foram randomizados em dois grupos (A e B). O grupo A recebeu em seu telefone móvel um aplicativo de mídia com os passos da inaloterapia, enquanto o grupo B recebeu as mesmas informações apenas de forma escrita. Após 15 dias, fez-se um pós-teste. Os resultados (pré e pós) foram analisados por dois pneumologistas pediátricos. RESULTADOS: Dos 66 profissionais, 87,9% eram do sexo feminino. Num escore total possível de 10, a média das notas obtidas no pré-teste foi de 5,3 ± 3 e as do segundo teste 7,5 ± 2 (p < 0,000). Não houve diferenças significativas na comparação os dois grupos (p = 0,726). Os profissionais de enfermagem apresentaram a menor média nas provas iniciais (2,3 ± 2), porém foi o grupo que aprendeu mais com a intervenção e apresentou média similar aos outros grupos na segunda prova (6,1 ± 3). CONCLUSÃO: Houve melhoria significativa no conhecimento sobre inaloterapia em todas as categorias profissionais com o uso de ambos os métodos. Isso comprovou que a educação, quando oferecida aos profissionais, modifica positivamente a prática médica.

OBJECTIVES: Inhalation therapy is the main treatment for asthma and its adequate use has been a factor responsible for disease control; therefore, the aim of the study was to determine whether a digital media tool, which features portability on mobile phones, modifies the assimilation of the inhalation technique. METHODS: A total of 66 professionals working in the health care area with the pediatric population were selected. They were submitted to a pre-test on their knowledge of inhalation therapy. The professionals were randomized into two groups (A and B). Group A received a media application on their mobile phones showing the steps of inhalation therapy, while group B received the same information in written form only. A post-test was applied after 15 days. The results (pre- and post-) were analyzed by two pediatric pulmonologists. RESULTS: Of the 66 professionals, 87.9% were females. Of a total possible score of ten, the mean score obtained in the pre-test was 5.3 ± 3, and in the second test, 7.5 ± 2 (p < 0.000). There were no significant differences when comparing the two groups (p = 0.726). The nurses had the lowest mean scores in the initial test (2.3 ± 2); however, they were the group that learned the most with the intervention, showing similar means to those of other groups in the second test (6.1 ± 3). CONCLUSION: There was significant improvement in knowledge about inhalation therapy in all professional categories using both methods, demonstrating that education, when available to professionals, positively modifies medical practice.

OBJETIVO: Comparar a cicatrização da parede abdominal de coelhos expostos à nicotina e submetidos à abdominoplastia utilizando 2-octil cianoacrilato ou nylon na síntese cirúrgica. MÉTODOS: Utilizou-se 32 coelhos. Estes foram distribuídos em subgrupos: A1, A2, B1 e B2. O grupo A recebeu solução de NaCl 0,9%; o B recebeu nicotina, ambos durante 14 dias do pré-operatório. Nos subgrupos A1 e B1 foi realizada abdominoplastia e sutura com "nylon"; enquanto A2 e B2 a síntese ocorreu com cianoacrilato. A eutanásia ocorreu no 14º dia do pós-operatório. Na pesquisa avaliou-se: processo inflamatório, proliferação fibroblástica, colágeno, neovascularização, epitelização macro e microscópica das cicatrizes. RESULTADOS: Observou-se presença de eosinofilia em todas as cicatrizes expostas ao cianoacrilato, e aumento significativo da neovascularização no subgrupo B2 em comparação com o A2 (p=0,037). Demais variáveis não apresentaram diferença estatística. CONCLUSÕES: A nicotina não influenciou o processo inflamatório, a proliferação fibroblástica, a presença de colágeno e a epitelização. A neovascularização indicou imaturidade cicatricial na comparação dos grupos A2 e B2. A eosinofilia nas cicatrizes reparadas com cola indica que a substância atuou como alergeno.

PURPOSE: To compare the wound healing of the abdominal wall of rabbits exposed to nicotine and submitted to abdominoplasty using 2-octyl cyanoacrylate or nylon thread for the surgery suture. METHODS: Thirty two rabbits were used. They were divided in subgroups: A1, A2, B1 e B2. Group A received saline 0.9%; group B received nicotine, both groups for 14 days before surgery. We performed an abdominoplasty with a nylon suture into the A1 and B1 subgroups; as for A2 and B2 groups the suture was performed with cyanoacrylate. The euthanasia happened in the 14th post-operative day. After, we evaluated: swollen process, fibroblast proliferation, collagen, neovascularization, and macroscope and microscope epithelization of the scars. RESULTS: We observed the presence of eosinophils in all scars exposed to the cyanoacrylate, and a significant increase of neovascularization in the subgroup B2 comparing to the A2 one (p=0.037). The other variables haven't showed any statistical difference. CONCLUSIONS: Nicotine hasn't influenced the swollen process, the fibroblast proliferation, the presence of collagen, neither the epithelialization. The neovascularization showed cicatricial immaturity when comparing group A2 to group B2. The eosinophils in the scars repaired with glue showed that the substance has acted as an allergen.

O trabalho foi conduzido na UNESP, Jaboticabal-SP, de setembro/2003 a janeiro/2004, com objetivo de avaliar a viabilidade da consorciação de pimentão com as culturas de repolho, rúcula, alface e rabanete. O experimento constou de 15 tratamentos, correspondentes a 10 cultivos consorciados (combinações das cinco hortaliças) e cinco monocultivos. Utilizou-se o delineamento experimental em blocos casualizados, com seis repetições. Foram utilizados os híbridos Magali R e Kenzan, respectivamente, para pimentão e repolho; e as cultivares Vera, Cultivada e Crimson Gigante, respectivamente, para alface, rúcula e rabanete. As produtividades de pimentão e repolho em cultivo consorciado não diferiram significativamente das obtidas em monocultivo. Maior massa fresca de parte aérea de plantas de alface (438,86 g/planta) foi observada quando a alface foi consorciada com pimentão, diferindo estatisticamente dos demais cultivos que obtiveram em média 323,05 g/planta de alface. Aumento na produtividade de raízes comerciais de rabanete foi observado quando consorciado com pimentão, porém, foi significativamente superior apenas ao cultivo consorciado de pimentão+repolho+rabanete. A massa fresca da parte aérea da rúcula mostrou diferença estatística apenas entre os consórcios de pimentão+rúcula+alface e pimentão+repolho+rúcula. Exceto o consórcio pimentão+repolho que obteve índice de uso eficiente da terra (UET) de 1,92; todos os outros consórcios apresentaram UET superior a 2,0, com maior UET (2,64) obtido no consórcio pimentão+alface. A superioridade de 92 a 164% na produção de alimento por área dos consórcios sobre os monocultivos, demonstra a viabilidade dos policultivos e maior eficiência do uso da terra.

This work was carried out in Jaboticabal, São Paulo State, Brazil, from September 2003 to January 2004, to evaluate the feasibility of an intercropping system of pepper with cabbage, rocket, lettuce and radish, in relation to their monocultives. The experiment consisted of 15 treatments, corresponding to 10 intercropping and five monocultives. The experimental design was a radomized block with six replications. The hybrid Magali R and Kenzan were used, respectively, for pepper and cabbage; and cultivars Vera, Cultivada and Crimson Gigante, respectively, for lettuce, rocket and radish. Yields of pepper and cabbage in intercropping did not differ significantly to that obtained in monocultive. The largest fresh mass of the aerial part of lettuce (438.86 g/plant) was observed in lettuce and pepper intercropping cultivation. In the other cultivations, 323.05 g/plant was obtained of lettuce. Increase in yield of commercial roots of radish was observed in radish and pepper intercropping, however, it was significantly larger to the intercropping cultivation of the pepper+cabbage+radish only. The fresh mass of the aerial part of the rocket showed statistical difference between pepper+rocket+lettuce and pepper+rocket+cabbage intercropping. Except for pepper+cabbage intercropping with land efficient use (LEU) of 1.92, all the intercropping cultives showed LEU higher than 2.0, with highwest LEU (2.64) obtained with pepper+lettuce intercropping. The better results obtained with intercropping in relation to production of food per area, demonstrate the viability of policultives and better land efficient use.

OBJETIVO: Avaliar o impacto de novas medidas de prevenção e tratamento para infecções incisionais em cirurgia de revascularização do miocárdio (RM). MÉTODO: Estudo retrospectivo incluindo 468 pacientes submetidos a RM com circulação extracorpórea, distribuídos em Grupo A (n=224) e Grupo B (n=244), de pacientes operados antes e após a adoção do novo protocolo, respectivamente. Análise comparativa entre os grupos procurou detectar a incidência de infecções superficiais e profundas na incisão para esternotomia, de recorrências e reinternações. RESULTADOS: Quanto aos fatores de risco relacionados a hábitos e doenças dos pacientes, aspectos cirúrgicos e hospitalares, ocorreram diferenças entre os grupos quanto a maior utilização da artéria mamária (p=0,003) e menor tempo de intubação orotraqueal (p=0,001) no Grupo B. Infecções incisionais - no Grupo A foram 44 (19,6%) casos, sendo 33 (14,7%) superficiais e 11 (4,9%) profundas; no Grupo B foram 13 (5,3%) casos com 10 (4,1%) superficiais e três (1,2%) profundas, sendo significativa a diferença quanto ao número total de infecções incisionais (p<0,001), superficiais (p<0,001) e profundas (p=0,037). As recorrências foram de 36,3% e 7,7%, respectivamente para os Grupos A e B (p=0,102). Ocorreram 21 reinternações relacionadas à infecção incisional no Grupo A e 3, no Grupo B (p<0,001). CONCLUSÃO: Para este grupo de pacientes, as mudanças adotadas resultaram em redução nas infecções incisionais e também diminuíram as reinternações relacionadas a este aspecto.

OBJECTIVE: To assess the impact of new preventive measures of surgical site infections after coronary artery bypass graft (CABG) surgery. METHOD: A retrospective study of 468 patients who underwent CABG surgery with cardiopulmonary bypass was performed. These patients were distributed into two groups: Group A (n=224) and Group B (n=244), respectively before and after a new protocol. The two groups were compared by statistical analysis to determine differences in risk factors, the incidence of sternotomy surgical site infections (superficial and deep), recurrent infections and hospital readmission. RESULTS: There was a greater use of internal thoracic artery grafts (p=0.003) and a shorter time of mechanical ventilation (p=0.001) in Group B. Surgical site infections occurred in 44 patients of Group A (19.6%); 33 superficial (14.7%) and 11 deep (4.9%) while in Group B only 13 patients had this complication (5.3%); 10 superficial (4.1%) and three deep (1.2%) surgical site infections. Significant improvements were seen in the total number of surgical site infections (p<0.001), of superficial infections (p<0.001) and of deep infections (p=0.037). There were 36.3% and 7.7% of recurrent infections in Groups A and B, respectively (p=0.102). Hospital readmissions due to surgical site infections were 21 in Group A and three in Group B (p<0.001). CONCLUSION: The new preventive measures and treatment for surgical site infections after CABG surgery in this series of patients, significantly reduced the incidence of sternotomy surgical site infections and hospital readmissions related to this complication.

Este trabalho relata um caso de feohifomicose subcutânea causado por Exophiala jeanselmei em um paciente que havia recebido transplante de coração e mantinha terapia com micofenolato mofetil, tracolimus e prednisone. As lesões tiveram início após trauma na perna inferior direita que evoluíram produzindo múltiplos nódulos e úlceras. Diagnóstico foi realizado através de avaliação histológica e de características macroscópicas e microscópicas da cultura das lesões da pele. O paciente fez uso de itraconazol em concentração de 200 mg/dia durante três meses, não se observando no entanto, melhora das lesões. Após este período, o paciente foi tratado com anfotericina B a uma concentração de 0,5 mg/Kg/dia totalizando 3,8 g. Após quatro meses de tratamento as lesões mostraram melhora evidente, verificando-se fechamento das fístulas e cicatrização das lesões.

We report a case of phaeohyphomycosis caused by Exophiala jeanselmei in a cardiac transplant recipient maintained on immunosuppressive therapy with mycophenolate mofetil tacrolimus and prednisone. The lesion began after trauma on the right leg that evolved to multiple lesions with nodules and ulcers. Diagnosis was performed by histological examination and culture of pus from skin lesions. Treatment consisted of itraconazole (200 mg/day) for three months with no improvement and subsequently with amphotericin B (0.5 mg/Kg per day to a total of 3.8 g intravenously). After four months of treatment, the lesions showed marked improvement with reduction in the swelling and healing of sinuses and residual scaring.

OBJECTIVE: To analyze the morphology of epididymis and tunica vaginalis as well as their anatomical anomalies in patients with testicular torsion. MATERIALS AND METHODS: We studied 25 patients (50 testes) aged between 12 and 23 years (mean 15.6). Torsion length ranged from 2 hours to 2 days (mean 8 hours). Epididymal anatomy was classified in 6 groups: Type I - epididymis united to the testis by its head and tail; Type II - epididymis totally united to the testis; Type III - disjunction of epididymal tail; Type IV - disjunction of epididymal head; Type V - total disjunction between testis and epididymis, and Type VI - epididymal atresia. The type of torsion was classified in 3 groups: Group A - intravaginal torsion; Group B - extravaginal torsion and Group C - torsion due to long mesorchium. RESULTS: Of the 50 analyzed testes, 40 (80%) presented bell clapper deformity (with 21 presenting intravaginal torsion); 8 testes (16%) had long mesorchium (4 with torsion), and only 2 (4%) presented normal anatomy in the tunica vaginalis. The most frequently found anatomical relationship between testis and epididymis was Type I - 38 cases (76%); Type II relationship was found in 6 cases (12%) and Type III relationship was found in 6 cases (12%). CONCLUSIONS: Intravaginal torsion is the most frequent type, and torsion due to long mesorchium is associated with cryptorchism. The most frequently found anatomical relation between testis and epididymis in the study group was Type I.
