ResumoO objetivo do presente trabalho foi avaliar os prontuários dos pacientes cuja cultura micológica do pêlo, em meio Ágar Sabouraud dextrose, suplementado com cloranfenicol e ciclohexamida, foi positiva para dermatófitos, e realizar um levantamento da casuística de dermatofitose. Foram avaliados 136 prontuários de pacientes (114 caninos e 22 felinos) com dermatofitose atendidos em período de 54 meses, no Hospital Veterinário da UNESP de Botucatu. Pela análise dos resultados, observou-se que a maioria dos cultivos foi positiva para M. canis. Não foi observada diferença estatística quanto ao sexo dos animais. Os cães de raça definida foram mais acometidos. A maior parte dos felinos era sem raça definida. A maioria dos humanos e animais que mantinham contato com os pacientes não apresentava lesões de pele. 32,5% dos cães apresentavam prurido de intensidade moderada, enquanto nos gatos o prurido estava ausente em 77,3% dos casos. 69,3% dos animais não apresentavam sinais clínicos não dermatológicos. A média aproximada de idades nos caninos foi de quatro anos e de três anos nos felinos. Não houve diferença estatística para a ocorrência da dermatofitose nas diferentes estações do ano. Dos animais avaliados com a Lâmpada de Wood, 40,9% dos cães e 33,3% dos gatos foram positivos. A maior parte dos cães apresentava lesões generalizadas, enquanto na maioria dos gatos eram localizadas. As lesões mais comumente observadas foram: alopecia, crostas e eritema.

ResumoO presente trabalho teve como objetivo fazer um levantamento da casuística de doenças dermatológicas auto-imunes e atualizar os dados referentes à ocorrência de lupus eritematoso discóide na população canina e felina atendida pelo Serviço de Dermatologia Veterinária da FMVZ-UNESP, campus de Botucatu, incluindo a espécie, sexo, raça, idade, localização e caracterização das lesões. Com a análise dos resultados, concluiu-se que a ordem de ocorrência de acordo com o número de casos de doenças dermatológicas auto-imunes nos animais atendidos pelo setor de dermatologia no período de 1988 a 2007 é: lupus eritematoso discóide, pênfigo foliáceo, síndrome úveo-dermatológica, pênfigo vulgar, lupus eritematoso sistêmico, eritema necrolítico migratório, eritema multiforme e pododermatite plasmocitária. Dos animais com lupus eritematoso discóide, todos eram da espécie canina, sendo a maioria fêmea e sem definição racial. As raças mais acometidas por lupus eritematoso discóide foram: Pastor Alemão e Akita e a média das idades foi de 56 meses. Notou-se que a maioria das lesões era localizada em plano nasal, narinas e região periocular. As lesões mais comumente observadas foram: crosta, despigmentação e eritema.

ABSTRACT:Envenomations caused by Loxosceles (brown spider) have been reported throughout the world. Clinical signs associated to bites of these spiders involve dermonecrotic lesions and intense local inflammatory response, besides systemic manifestations such as intravascular hemolysis, thrombocytopenia, disseminated intravascular coagulation and acute renal failure. The present study aimed to report and to describe dermonecrotic lesions probably caused by a Loxosceles envenomation in a four year-old poodle female dog, treated at the Dermatology Service of the Veterinary Hospital of the Veterinary Medicine and Animal Husbandry School, São Paulo State University, Botucatu, Brazil. Initially, the animal presented two skin lesions with blackish aspect that evolved into ulcerative crusts. The owner reported the presence of a brown spider near the place where the animal spent most of the time. Histological examination of lesions revealed necrosis of the epidermis extending to adnexa and panniculi, which is compatible with Loxosceles bite reaction. The animal was treated with systemic antibiotic and local curatives. Lesions healed by second intention in two months.

Objectives The aim of this study was to perform neonatal clinical assessments at birth to identify newborn kittens at risk according to type of delivery, thus allowing immediate intervention and increasing their chances of survival. Methods This study compared Apgar scores, reflexes and clinical parameters (temperature, weight, blood glucose and peripheral oxygen saturation [SpO2]) between eutocic neonates and those delivered by emergency cesarean section. The animals were evaluated at birth and after 10 and 60 mins. Results Thirty-two neonates were evaluated, with 19 animals in the eutocic group (EG) and 13 animals in the cesarean group (CG). When comparing groups, CG neonates had significantly lower Apgar scores ( P <0.0001), lower SpO2 ( P = 0.0535), higher blood glucose ( P = 0.0009), reduced reflexes ( P <0.0001) and lower respiratory rates ( P <0.0001) at birth and after 10 and 60 mins than EG neonates. Apgar scores positively correlated with parameters such as heart rate, reflex score, SpO2 and weight. The mortality rate in evaluated newborns was 15.6% (5/32). The early mortality rate (0–2 days old) was 80% (4/5) and the late mortality rate (3–30 days old) was 20% (1/5). Conclusions and relevance This study showed lower vitality in cats delivered by emergency cesarean section than in those delivered through eutocic birth. In general, neonates delivered by cesarean section have greater depression and low vitality at birth and may require advanced resuscitation procedures. The evaluations carried out in this study identified newborns with low vitality and those requiring advanced resuscitation, thus allowing immediate intervention. Apgar and reflex scores for feline neonates were suggested. Newborn-specific clinical assessment with these feline vitality scores allows the identification of at-risk neonates. Care immediately after birth increases the chance of survival among these patients.

e describe a case of a rare cystic, exophytic salivary gland tumor diagnosed in a fetus at an estimated gestational age of 25 weeks. The combined use of 2-dimensional (2D) and 3-dimensional (3D) sonography allowed determination of the tumor's origin. Sonographically guided aspiration of the tumor's content produced fluid with the consistency of mucus. Detection of amylase in the fluid confirmed that the lesion was of salivary origin and established the diagnosis of a ranula. Prenatal decompression of the ranula allowed spontaneous vaginal delivery of a full-term girl with excellent Apgar scores at 1 and 5 minutes. Case ReportA 13-year-old pregnant patient was referred to our prenatal diagnostic unit for a sonographic examination. The estimated gestational age based on her last menstrual period was 25 weeks. The patient was found to have a singleton gestation with a female fetus. Biometric measurements with 2D sonography showed the fetal age to be consistent with the patient's last menstrual period and revealed a cystic tumor measuring 5.0 × 4.0 cm protruding through the mouth. The tumor seemed to originate in the sublingual area of the mouth. Color Doppler scanning revealed no vascular flow in the tumor. We were able to observe the wide-open mouth of the fetus and to confirm the sublingual origin of the cyst more precisely with 3D sonography (Figure 1). A sonographic anatomic survey revealed that there was fluid in the stomach of the fetus. All other fetal organs and the amniotic fluid index (14) were normal. Cytogenetic anal-

With the purpose of shedding light on some doubts in veterinary oncology, the present article intends to compare the results of histopathological and immunohistochemical examinations of unspecific round cell neoplasia, to realize immunophenotyping of canine lymphoma cases, to establish the T or B origin of neoplastic cells, and to determine the degree of proliferation and apoptosis of lymphomas by immunohistochemistry. Of 11 animals presenting immunohistochemical diagnosis of lymphoma, five had been diagnosed as Lymphoma by HE staining of histopathological slides and six had been classified as unspecific round cell neoplasia. All cases submitted to immunohistochemical examination were T-cell lymphomas. There was a positive correlation between cell proliferation and apoptosis. The comparison among histopathological and immunohistochemical results obtained in the cases examined in the present study suggested that immunohistochemistry is essential for the differentiation of round cell neoplasia.
