Investigou-se a prevalência de infecções parasitárias do apêndice cecal e suas relações com a apendicite. Dos 1.600 apêndices estudados 24 (1,5%) apresentaram infecção parasitária. Enterobius vermicularis foi encontrado em 23 casos (95,8%) e Taenia sp em apenas um (4,2%). Dezesseis pacientes (66,7%) eram menores de 10 anos; 15 eram masculinos e 9 femininos. A análise histopatológica demonstrou inflamação aguda supurativa em 12 casos (50%), eosinofilia em 13 (54,2%) e hiperplasia linfóide em 10 (41,7%). Complicações como peritonite ocorreram em 11 e gangrena em 3 casos. As infecções parasitárias do apêndice são causa pouco freqüente de apendicite aguda em crianças e adolescentes.

FUNDAMENTOS: O aquarismo a cada dia ganha novos adeptos no Brasil. Impulsionado por belos peixes e objetos de decoração, o hábito pode trazer problemas como infecções e envenenamentos por diversos animais. OBJETIVOS: Demonstração dos animais causadores e dos quadros clínicos envolvidos com estes acidentes, das infecções cutâneas encontradas após traumas e das medidas terapêuticas e preventivas para controle do problema, pouco conhecido pela população em geral. MÉTODOS: Utilizou-se um estudo prospectivo para a detecção de acidentes por animais e infecções ocorridas após traumas em aquários. Estes dados serviram de base para um estudo epidemiológico, clínico e terapêutico sobre o problema. RESULTADOS: em cerca de 300 acidentes por animais aquáticos, 12 ou 4% do total foram causados por animais venenosos em aquários. Cinco infecções bacterianas e uma fúngica foram identificadas após traumas em aquários. CONCLUSÕES: Os acidentes em aquários domésticos e comerciais são relativamente comuns e podem acarretar infecções cutâneas e ferimentos por animais venenosos ou traumatizantes. Os proprietários de aquários na maioria das vezes não têm informações sobre estes acidentes. Os autores fornecem as espécies de microorganismos e animais mais freqüentemente envolvidas com ferimentos e as medidas terapêuticas e preventivas adequadas ao manejo do problema.

Comparamos os métodos de Imunofluorescência Indireta (IFI), Imunodifusão Radial Dupla e Aglutinação, para a pesquisa de anticorpos em soros, na tripanossomíase experimental por Trypanosoma evansi, em cobaias. Foram obtidas 20 amostras de soro correspondentes às 4 primeiras semanas de infecção. A IFI foi positiva em apenas 6 animais, com títulos variando de 1:4 a 1:16. Os títulos mais altos foram observados na 3ª semana pós-infecção. Anticorpos aglutinantes foram observados a partir da 1ª semana pós-infecção e, após a 2ª semana, todos os animais apresentaram reação de aglutinação positiva, com títulos variando de 1:8.000 a 1:250.000. O tratamento dos soros com 2-Mercapto-etanol inibiu a reação de aglutinação, sugerindo ser IgM a principal classe dos anticorpos presentes no soro dos animais infectados. Não se constatou a presença de anticorpos precipitantes durante todo o curso da infecção.

The aim of this study was evaluate the effectiveness of the sodium diclophenac on the mydriasis induced by drugs and on the tearing, blepharospasm and photophobia in normal individuals that received mydriatic or cycloplegic eyedrops. We observed that there was not increase of the pupil diameter with the use of the diclophenac (f = 0,52). The photophobia symptom was mainly present in the patients with dark iris and that received the cycloplegic drops (p < 0,01). The authors concluded that there is not benefit in the use of the sodium dyclophenac eyedrops for the mydriasis increase or the decrease of the ocular symptoms in routine ophthalmologic examination.

Study model: observacional, retrospective. Objective: to determine the frequence of the ametropic errors and other ocular problems in children with 2 to 8 year-old at Piracicaba - SP. Patients and Method: During the school year of 2000, 1001 children enrolled at the public schools of Piracicaba - SP, age ranged from 2 to 8 years old, were referred to complete ophthalmological exam. Visual acuity was previously determined using Snellen chart, applied by school teachers. Those children presenting visual acuity equal or less than 0.8, visual complaints or visual disorders were selected to appointment. Results: 51 children (5.09%) did not attended to examination. 950 children were submitted to complete ophthalmological exam. Ametropic errors were found 70.84% of the children. The most prevalent refractive errors were Hypermetropic Astigmatism (49.62%) and Hypermetropia (32,98%). Anisometropia was found in 1.78% children. Other ocular disabilities accounted for 10.21% of the examined children, such as strabismus (3.36%), eyelid changes, allergic conjunctivitis, congenital dacryostenosis, optic atrophy, corioretinitis and congenital glaucoma. Conclusion: The frequence of ocular problems observed let us to conclude the screening programs are valid surveys on decreasing rates of preventable blindness in our country.

This study was performed to standardize parasite egg counting in feces of sheep by TF-Test, in addition to compare this test to the Gordon & Whitlock technique (G&W). Twenty-four lambs were artificially infected with Haemonchus contortus throughout 12 weeks. At the end of this time, faecal samples were taken and animals were slaughtered for worm identification and counting. G&W and TF-Test methods were carried out on each fecal sample. Both tests showed Haemonchus eggs in 95.8% of the samples (P>0.05). The correlation coefficients (r) between fecal egg counts (FEC) using G&W × Total Worm Count (TWC) were r=0.52 (not transformed data) and r=0.85 (transformed data); between FEC by TF-Test × TWC were r=0.51 (not transformed data) and r=0.87 (transformed data). Other 100 fecal samples were taken from naturally infected sheep. In these animals, the G&W and TF-Test methods showed 85% and 86% of fecal samples positive for Strongylidea eggs, respectively (P>0.05). Also in those animals, Eimeria oocysts were found in 33% of fecal samples by TF-Test, whereas in the G&W only 12% were positive (P<0.001). For Strongyloides spp., TF-Test showed 15% of positive fecal samples, whereas G&W showed 5% (P<0.05). In conclusion, both methods were efficient to diagnose gastrointestinal nematodes and TF-Test was superior to diagnose oocysts of Eimeria spp. and eggs of Strongyloides spp; conversely, Strongylidea eggs counting using TF-Test was underestimated.

Purpose: To describe alterations observed in patients with congenital clinical anophthalmia and the occurrence of association with other ocular and extra ocular abnormalities. Methods: An observational retrospective study was conducted evaluating 12 patients with congenital clinical anophthalmia at Faculdade de Medicina de Botucatu-UNESP, between 1992 and 2005. In those patients it was observed the ocular abnormalities, severity, laterality, follow-up and to systemic abnormalities associated. The congenital clinical anophthalmia have been associated to major severity abnormalities extra-oculars, mainly when the anophthalmia was bilateral, such agenesis of corpus callosum, others craniofacial anomalies and cardiac defects. In the cases unilateral, the alteration associated more frequently was the facial asymmetry, showing the direct correlation between anophthalmos and development of orbit and face. Conclusion: There was relation between congenital clinical anophthalmia and ocular abnormally and extra-ocular abnormally. Patients with bilateral anophthalmos disease have more severe alterations. anophthalmia congenital attends a course with abnormalities of development of the face.

The feline infectious respiratory disease is the most common diagnosed infection in the veterinary clinic routine, being the Feline Herpesvirus1 the most important causal agent. Once infected, the cat will become a lifetime latent carrier, experiencing episodes of viral reactivation and spontaneous spread especially when there is a stress factor involved. This virus acts in the upper respiratory system and is also associated with eye diseases. The diagnosis is made by viral isolation and treatment protocol is based on a topic antiviral therapy, even though many of them are epiteliotoxic and may progress with intense discomfort in felines.The purpose of this paper is to describe the main ocular manifestations and syndromes seen in cats suffering from feline herpesvirus. Conjunctivitis, epithelial and stromal keratitis, corneal ulceration and indolent ulcers are the main ocular manifestations associated with viral infection, whereas symblepharon, keratoconjunctivitis sicca, proliferative keratitis and corneal sequestration are the main eye syndromes that can be observed in infected animals.
