ABSTRACT

Myelodysplastic syndromes (MDS) are a group of clonal stem cell diseases characterized by ineffective hematopoiesis, bone marrow hyperproliferation, cytopenias in peripheral blood and risk of transformation into acute leukemia. We decided to investigate the effects of a soy concentrate on MDS patients based on the follow-up results of a 61 year-old Japanese female patient who was diagnosed with MDS and refractory cytopenia with multilineage dysplasia in 2003 (hemoglobin = 11g/dL; white blood cells count = 2,500/uL and platelets = 25,000/uL; marrow with mild dysplasia and normal karyotype; paroxysmal nocturnal hemoglobinuria was excluded). She started using soy as a dietary supplementation in May 2004 and presented a gradual increment in blood counts, achieving normalization approximately eight months afterwards. Among the soy components, the main compounds with anti-carcinogenic activity are the isoflavones (genistein and daidzein). Based on these lines of evidence, we proposed to administer daily a standard soy concentrate to 14 MDS out-patients for a minimum period of three months and maximum of 12 months, in an attempt to evaluate prospectively the possible increase in hemoglobin, neutrophils and platelet counts. A historical control group was used to compare results. The use of a soy concentrate in a standardized manner was associated with an increase in neutrophil and/or platelet counts in some cases, but spontaneous increments were also observed in historical controls. This preliminary study does not allow establishing a relation between soy supplementation and blood cell count increase.


As síndromes mielodisplásicas (SMD) são um grupo das doenças clonais de células-tronco caracterizado por hematopoese ineficaz, hiperproliferação de medula óssea, citopenias no sangue periférico e risco de transformação para leucemia aguda. Decidimos investigar os efeitos de um concentrado de soja em pacientes com SMD com base no fato de termos o seguimento de uma paciente japonesa, de 61 anos de idade, que foi diagnosticada em 2003 com SMD, citopenia refratária com displasia subtipo multilinhagens (hemoglobina = 11 g/dL; contagem de glóbulos brancos = 2.500/uL e plaquetas = 25.000/uL; medula com displasia leve e cariótipo normal; hemoglobinúria paroxística excluída), e que começou a usar a soja como suplemento alimentar em maio de 2004, apresentando gradual aumento da contagem das células sanguíneas, atingindo a normalização cerca de oito meses depois. Entre os componentes da soja, os principais compostos com propriedades anticarcinogênese são as isoflavonas (Ge nisteína e daidzeína). Com base nessas linhas de evidência, foi proposto oferecer diariamente um concentrado de soja padrão, por um período mínimo de três meses e máximo de doze meses, a 14 pacientes ambulatoriais, na tentativa de avaliar, prospectivamente, o possível aumento de hemoglobina, neutrófilos e plaquetas. Um grupo controle histórico foi utilizado para comparar os resultados. O uso de um concentrado de soja de forma padronizada foi associado ao aumento na contagem de neutrófilos e/ou de plaquetas em alguns casos, mas aumentos espontâneos também foram observados em controles históricos. Este estudo preliminar não permite estabelecer relação entre o uso de soja e o aumento na contagem sanguínea.

ABSTRACT

Enteropathogenic Escherichia coli (EPEC) strains are important agents of infantile diarrhea all over the world, gaining even greater importance in developing countries. EPEC have also been isolated from various animal species, but most isolates belong to serotypes that differ from those recovered from humans. However, it has been demonstrated that several isolates from non-human primates belong to the serogroups and/or serotypes related to those implicated in human disease. The objective of this study was to evaluate the genetic differences between thirteen strains isolated from non-human primates and the same number of strains isolated from human infections. Human isolates belonged to the same serogroup/serotype as the monkey strains and the evaluation was done by analysis of random amplified polymorphic DNA. Dendrogram analysis showed that there was no clustering between human and monkey strains. Human and non-human isolates of the EPEC serotypes O127:H40 and O128:H2 shared 90 and 87 percent of their bands, respectively, indicating strong genomic similarity between the strains, leading to the speculation that they may have arisen from the same pathogenic clone. To our knowledge, this study is the first one comparing genomic similarity between human and non-human primate strains and the results provide further evidence that monkey EPEC strains correlate with human EPEC, as suggested in a previous investigation.

ABSTRACT

The occurrence of serum antibodies to Borrelia burgdorferi in professionals in close contact with wild animals was determined. Seventy eight technicians workers coming from two São Paulo public institutions housing wild animals had their blood collected (serum samples). All samples were submitted to ELISA for IgM and IgG antibodies against Borrelia burgdorferi. The results showed five positive (6.4 percent), two suspect (2.6 percent) and 71 negatives (91 percent) samples. Based on positive results it is concluded that the infection level is higher to that detected in the general population and similar to values of endemic areas, concluding that this assessed population could be considered at risk for Lyme disease.

ABSTRACT

Relata-se infecção septicêmica em cobras d’água (Helicops modestus) causada por Proteus vulgaris. Os animais iniciavam o processo apresentando abscessos puntiformes de coloração esbranquiçada na pele e após rápida evolução, morriam (100% de mortalidade). Descreve-se, ainda, a sensibilidade do P. vulgaris isolado dos animais a drogas antibacterianas.

ABSTRACT

Five hundred and forty-five samples of hair, feathers, skin, scale and nails scrapings of 28 different species, including humans domestic animals, laboratory animals and wild animals were analysed. Samples were examined by direct microscopy after 30 per cent KOH clarification, and cultured in dextrose agar Sabouraud, Mycobiotic agar (dextrose 10 g/L, chlormicetine 0.05 g/L, cycloheximide 0.5 g/L), and in brain heart infusion agar (BHI agar). The results obtained after isolation and identification were: bacteria 53.94 per cent, non-dermatophytes mycelial fungi 42.56 per cent, dermatophytes 17.43 per cent, yeasts 13.57 per cent, and acari 2.93 per cent, and 19.26 per cent were negative. Staphylococcus were the most prevalent bacteria and among dermatophytes the most prevalent were M. canis; among non-dermatophytes mycelial the Aspergillus sp, and Candida sp were the most common yeasts isolated

ABSTRACT

Relatam-se dois surtos de salmonelose em cobaias (Cavia porcellus), envolvendo um total de 70 animais mantidos em biotério, que manifestaram emaciaçäo progressiva, prostraçäo, hipertermia, pelos arrepiados e rarefeitos. Após o início dos sintomas, 48,57 por cento dos animais (34/70) evoluíram para a morte, sendo os demais sacrificados com o intuito de se controlar os surtos. Na necrópsia, colheram-se fragmentos de fígado, baço, rins, pulmöes e intestinos para exames histopatológico e microbiológico. Ao exame microbiológico obteve-se o isolamento de cepas caracterizadas bioquímica e sorológicamente como Salmonella typhimurium. O exame histopatológico dos fragmentos de órgäos corados pela hematoxilina-eosina revelou a presença de lesöes condizentes com quadro septicêmico por este microrganismo. O presenta trabalho alerta quanto ao risco existente na utilizaçäo de animais de experimentaçäo portadores dessa bactéria, já que poderiam comprometer experimentos por uma possível interferência nos resultados, além de representarem fonte de infecçäo em biotérios e laboratórios

ABSTRACT

Se presentan 18 casos de ileo biliar estudiados en un periodo de 7 anos en el Hospital General del Centro Medico Nacional.Existio predominio del sexo femenino (94, 4%), con edades de 46 a 85 anos. Todos los pacientes presentaron cuadro de obstruccion intestinal, tanto clinica como radiologicamente. El diagnostico preoperatorio de ileo biliar solo se realizo en el 16.7% pero al efectuar un analisis retrospectivo de los estudios radiologicos se llego a la conclusion que debio ser mas elevado. El tipo de fistula biliar interna mas frecuente fue la colecistoduodenal (66,6%).Diez y siete enfermos fueron tratados quirurgicamente y la mortalidad global fue de 5.6%. La operacion con la que se obtuvieron mejores resultados fue la enterotomia y extraccion del calculo, no se recomienda el cierre de la fistula de primera intencion. En los pacientes con ileo biliar debe tratarse de llegar a un diagnostico correcto lo mas pronto posible, para efectuar el tratamiento oportuno y disminuir la morbimortalidad
