Estudo epidemiológico das dermatofitoses em cães e gatos atendidos no serviço de dermatologia da Faculdade de Medicina Veterinária e Zootecnia da UNESP - Botucatu

The objective of this study was to assess the medical records of the patients whose mycological culture of the hair in Sabouraud Dextrose Agar supplemented with chloramphenicol and cycloheximide was positive for dermathophytes, and review the cases of dermatophytosis. One hundred and thirty six medical records of patients (114 dogs and 22 cats) with dermatophytosis attended in a period of 54 months in the Veterinary Hospital of the UNESP - Botucatu were evaluated. Results obtained in this analysis have shown that the majority of the cultures were positive for Mycrosporum canis. There was no statistical difference between genders, but the number of defined breed dogs presenting dermatophytosis was higher than mongrel dogs. Among feline cases, however, there were a higher number of mongrel cats. The majority of the people and animals in contact with the patients did not report skin lesions. 32,5% of the dogs presented middle intensity itchiness, while in cats itchiness was absent in 77,3% of cases. 69,3% of the animals did not present clinical signs other than dermatological. Mean ages were 4 years in dogs and 3 years in cats. There was no statistical effect of season in the occurrence of dermatophytosis. Among animals submitted to Wood lamp evaluation, 40,9% of the dogs and 33,3% of the cats were positive for dermatophytes. Most dogs had generalized lesions, while the majority of cats presented focal lesions. The most common lesions observed were: alopecia, crusts and erythema.

Perfil dos alunos usuários de lentes de contato do curso de Medicina da Universidade Estadual Paulista - UNESP - Botucatu

OBJETIVO: Analisar o perfil dos usuários de lentes de contato entre os estudantes de medicina da Faculdade de Medicina de Botucatu da Universidade Estadual Paulista - UNESP - Botucatu (SP), quanto à ametropia, à aquisição, aos cuidados e às complicações. MÉTODOS: Foi aplicado um questionário aos alunos do 1º ao 6º ano de Medicina da Faculdade de Medicina de Botucatu da Universidade Estadual Paulista - UNESP - Botucatu (SP), perfazendo um estudo analítico transversal. RESULTADOS: Foram 566 entrevistados. Destes, 155 (27,4%) usavam lente de contato. Das lentes de contato usadas, 94,8% eram gelatinosas, e em 98,7% o grau era negativo. O descarte dessas lentes era mensal em 46,9% dos entrevistados e 63,9% a utilizavam, em média, 14 horas/dia. Faziam aquisição da lente de contato em óptica ou farmácia 14,1% dos estudantes. Faziam a higiene ao colocá-las e ao retirá-las dos olhos, 46,5%. As complicações referentes aos olhos vermelhos eram 51,0%; 44,5%, embaçamento; e 42,6%, sensação de corpo estranho, além de 4 estudantes relatarem ceratite. CONCLUSÕES: A maioria dos alunos utilizava lentes hidrofílicas, descarte mensal e grau negativo. A adaptação inadequada, aquisição de lentes de contato em ópticas ou farmácias e complicações graves ocorreram, mesmo nos usuários socioculturalmente considerados diferenciados. em vista disso, demanda a extrema necessidade de maior atenção na abordagem do tema em questão, a fim de prevenir o comprometimento visual permanente.

Efeitos da infusão contínua de cetamina sobre a pressão intra-ocular em cães hipovolêmicos anestesiados com desflurano

Compararam-se os efeitos de duas doses de cetamina, administradas em infusão contínua, sobre a pressão intra-ocular (PIO) de 18 cães submetidos à hipovolemia e à anestesia com desflurano. Promoveu-se a hipovolemia em todos os cães, retirando-se 40 ml de sangue/kg de peso. A anestesia foi induzida com desflurano, através de máscara facial, até que a intubação orotraqueal fosse permitida. Decorridos 30 minutos, para estabilização dos parâmetros, iniciou-se a infusão contínua de cetamina. Os cães foram distribuídos, aleatoriamente, em três grupos (n= 6). O grupo I (controle) recebeu solução salina estéril; o grupo II (GII) recebeu cetamina, na dose de 100mig/kg/min, e o grupo III (GIII), cetamina na dose de 200mig/kg/min. A PIO foi medida por tonometria de aplanação. Foram mensurados freqüência cardíaca (FC), ritmo cardíaco, pressão arterial média (PAM), débito cardíaco (DC), pressão venosa central (PVC) e pressão parcial de CO2 no final da expiração (ETCO2). O desflurano não influenciou os resultados da PIO, porém observou-se discreta ação da cetamina em todos os grupos. Foi possível estabelecer relação direta entre os valores de PIO e de ETCO2. A PIO apresentou relação direta somente com a ETCO2.

Efeito de diferentes relações volumoso: concentrado no consumo, digestibilidade aparente e partição da digestão da dieta de bovinos

Three steers equipped with ruminal and duodenal cannulas were fed roughage:concentrate ratios 80:20, 60:40 and 40:60 in order to study intake and apparent, rumen and post-rumen digestibilities. The roughage was ''coast cross'' (Cynodon dactylon) hay (5.67% CP and 83.30% NDF). Undigestible neutral detergent fiber (NDF) was used as dry matter (DM) flow marker. DM intake means were 77.99, 91.03 and 91.81g DM/kg BW0.75, for the 20, 40 and 60% concentrate diets, respectively. DM intake for the 20% diet was statistically (P < 0.05) different from the other two diets. Apparent digestion coefficient (%) of DM (50.48, 57.32 and 61.33), organic matter (OM) (52.03, 58.91 and 62.76) and gross energy (GE) (48.95, 56.40 and 60.00) increased significantly with the increase in concentrate ratio of the diets. For the following components the apparent digestion coefficients were not statistically different: NDF (44.54, 45.28 and 42.53), ADF (40.69 44.39 and 43.60), cellulose (51.54, 54.34 and 52.03), hemicellulose (49.63, 46.78 and 39.18) and starch (86.59, 91.89 and 93.21). DM, OM, NDF, ATF, cellulose and starch ruminal and post-ruminal digestibilities were not statistically different. But the ruminal digestibilities of hemicellulose (94.81, 90.26 and 85.99) and EG (93.85, 83.30 and 78.77) decreased significantly as the concentrate ratio of the diets increased. The post-ruminal digestibility of hemicellulose (5.19, 9.74 and 14.03%) and GE (6.12, 16.20 and 21.23%) increased as the concentrate ratio of the diets increased.

Detecção de herpesvírus bovino 5 (BoHV-5) em bovinos do Sudeste Brasileiro

This paper reports the detection of bovine herpesvirus type 5 (BoHV-5) by a specific nested PCR assay. Samples were collected from the central nervous system (CNS) of cattle from Minas Gerais and São Paulo States, Brazil. All animals died presenting neurological symptoms. Nineteen frozen CNS samples analyzed had been previously tested by fluorescence antibody test for rabies virus and showed negative results. Three paraffin-embedded brain tissue samples were examined by histopatology and the observed alterations suggested nonsuppurative meningoencephalitis. BoHV-5 was detected in five (22.7%) among 22 tested samples. The occurrence of BoHV-5 infection is reported in the Southeast region of Brazil, indicating that epidemiological studies should be carried out.

Hidrocistoma écrino e apócrino na pálpebra - Casuística na Faculdade de Medicina de Botucatu- São Paulo

Background - Hidrocystomas ecrine and apocrine may be observed in the eyelids. Objective - The purpose of this study was to observe the occurrence of eyelid hidrocystoma (eccrine or apocrine), as well as the relation between clinical and histopathological diagnosis. Patients and Methods - 42 patients were selected, with a total of 52 lesions, attended between January 1990 to April 1999, at the Botucatu Medical School, with diagnosis of hidrocystoma confirmed by histopathology diagnosis. Result - Hidrocystoma occurred in 0.07% of patients undergoing lesion removal during this period. Eccrine and the apocrine hidrocystoma were frequently observed in female patients, aged over 40 years. The clinical picture ranged from about 1 to 5 years. The lesions were mainly located in the lower eyelid and presented as a single lesion. The clinical diagnosis agreed with the histopathological diagnosis in 67.31% of the apocrine hidrocystomas, and 9.62% of the eccrine hidrocystomas. Conclusions - Apocrine hidrocystoma was the most frequently observed eyelid hidrocystoma. The correlation between clinical and histopathological diagnosis was higher for apocrine hidrocystomas.

Prevalência de papiloma vírus (HPV) perianal assintomático em pacientes portadores de HPV genital tratados no Hospital das Clínicas da Faculdade de Medicina de Botucatu

Introduction: Human Papillomavirus (HPV) infection is one of the Sexually Transmitted Diseases (STD) of greatest incidence and prevalence worldwide, and it is presently considered to be a pre-neoplastic lesion. Human Papillomavirus infection has totaled 23.4% of the sexually transmitted diseases reported to the Department of Health, and it is currently the most common in our country. Many patients are asymptomatic carriers. Methods: Twenty patients who had been previously treated for HPV due to genital lesions were referred for the conduction of anuscopy and colposcopy of the perianal region. Results: Males (80%) prevailed over females (20%). Of the total number of patients, only 2 showed lesions as examined by anuscopy (10%). However, 3 other patients showed lesions by means of colposcopy, thus increasing to 5 (25%) the total number of asymptomatic patients who presented perianal lesions. Of the total number of patients with lesions, 4 were males and 1 was a female. Conclusion: The presence of perianal lesions was observed in 10% of the patients with genital lesions by means of simple anal inspection. This figure increased to 25% when anal colposcopy was associated, thus showing the importance of conducting such examination on all patients with increased risk factors for HPV infection in the anal region.

Descripción inmunohistoquímica de la encefalitis en bovinos brasileños naturalmente infectados con el herpesvirus bovino tipo 5 (HVB-5)

Twelve cases of viral meningoencephalitis in Brazilian cattle were submitted to immunohistochemical analysis for inflammatory response description. All the cases showed severe neurological signs followed by death. Mild to moderate histological inflammatory changes in the brain and cerebellum characterized the neurological infection showing meningitis, mononuclear perivascular cuffing, gliosis, haemorrhage, and macrophages (gitter cells) accompanying great areas of malacia. None of the cases showed intranuclear inclusion bodies. However, in five of them it was possible to isolate the BoHV-5. In order to collect data to allow the description of the inflammatory response in these cases, brain samples from all of the cases were analyzed by immunohistochemistry using polyclonal antibodies against CD3 to detect T cells, and against GFAP to detect astrocytes. On the other hand, monoclonal antibodies were used against BLA to detect B cells and, against MAC 387 to detect macrophages. The results indicate different degrees of prominent astrocytic response, and at the same time, T lymphocytes constituted a high percentage of the mononuclear cells which characterized the inflammatory response.
