This study aimed to characterize ocular diseases in dogs naturally affected by visceral leishmaniasis in Teresina, Piauí State, Brazil. The diagnosis was made using parasitological exams of the bone-marrow and lymph-node samples. The main ophthalmological findings were uveitis, conjunctivitis, blepharitis, keratitis, and keratoconjunctivitis sicca. Normocytic normochromic anemia was the main hematological finding, followed by thrombocytopenia. Plasma proteins were also considered, and hyperproteinemia, hypergammaglobulinemia, and hypoalbuminemia were observed. Ocular histopathological examination revealed mild inflammation involving lymphocytes, monocytes, and macrophages. Results indicate the need to perform a differential diagnosis to rule out or establish the presence of Leishmania sp. in dogs presenting with ophthalmic lesions in endemic regions.

Background/Aims: The role of postoperative radiotherapy (PORT) in head and neck mucosal melanomas (HNMM) is not yet clearly defined. The aim of this study is to report the 21-year experience of the Brazilian National Cancer Institute in such treatment. Methods: From January 1983 to December 2003, 31 patients with confirmed histological diagnosis of HNMM underwent treatment at the Brazilian National Cancer Institute. Of these, 20 received radical treatment with surgery alone (8 patients – group 1) or surgery and PORT (12 patients – group 2). Results: Local control and the median time to local failure at 5 years were 75% and 14 months for group 1 and 83.5% and 40 months for group 2 (p = 0.06). The overall survival rates at 3 years were 37.5% for group 1 and 58% for group 2. At 5 years the survival rates were 25% for both groups (p = NS). When PORT was initiated within 60 days after surgery, there was a trend towards improvement in overall survival (p = 0.08). After univariate analysis, distant metastasis, location of primary disease and tobacco smoking were important prognostic factors. Conclusion: Early (<60 days) PORT for HNMM provides better local control with a longer disease-free survival.

Integrando as pesquisas sobre parasitoses na região do entorno do Parque Nacional Serra da Capivara, Piauí, Brasil, realizadas entre 1999 e 2001, o presente estudo tem como objetivo avaliar a situação epidemiológica da cisticercose humana no Município de João Costa, no Nordeste do Brasil. Foram obtidas informações clínico-epidemiológicas e coletadas amostras de sangue para testes sorológicos imunoenzimáticos (ELISA e Western blot), empregando cisticercos de Taenia crassiceps como antígeno. Na primeira etapa, em 1999, foram investigadas 169 pessoas com história confirmada ou suspeita de infecção/doença pelo complexo teníase-cisticercose, e seus familiares. Na análise, 13,6% das pessoas apresentaram soros reagentes para cisticercose pelo método ELISA. Na segunda etapa, em 2001, foram avaliadas 92 amostras de soro de indivíduos reativos para cisticercose detectados no primeiro momento e seus familiares, sendo que 24,0% das amostras de soro foram reagentes para cisticercose pelo ELISA, e 29,0%, pelo WB. Nessa mesma etapa, realizou-se inquérito coprológico em 701 pessoas, incluindo voluntários. A prevalência de parasitoses intestinais foi de 51,0%, tendo sido observada uma maior prevalência de protozoários (95,0%) em relação aos helmintos (5,0%). Os resultados do estudo indicam o caráter endêmico da cisticercose na área, além da elevada freqüência de protozooses intestinais.

RESUMO:As cadelas são animais multíparos de gestação curta que produzem, em geral, proles numerosas que podem atingir a maturidade sexual a partir de seis meses de idade. Na atualidade, o controle populacional da espécie canina e consequentemente das zoonoses deve ser contemplado em programas ou políticas públicas pelos gestores municipais e estaduais. A esterilização cirúrgica constitui a principal medida para esse controle. As drogas anticonceptivas principalmente as injetáveis para prevenir ou retardar o cio ou estro e não permitir uma fertilidade futura foram muito utilizadas na década de 80 e no início de 90 e continuam até os dias de hoje. O objetivo deste trabalho é analisar a prevalência e as principais implicações associadas ao uso de anticoncepcionais em cadelas atendidas no Hospital Veterinário Universitário "Médico Veterinário Jeremias Pereira da Silva" da Universidade Federal do Piauí, no período de janeiro de 2012 a julho de 2014, onde se pôde concluir que o uso de anticoncepcionais possivelmente está relacionado com a alta ocorrência de casos de piometra, neoplasia mamária e aborto. Palavras chave: Aborto, anticoncepção, neoplasia, piometra Pathological implications after contraceptive use in bitches located in Teresina-PIABSTRACT: Bitches are multiparous animals of short gestation, producing generally numerous offspring that can reach sexual maturity from six months old. Currently, the population control of the canine species and consequently of zoonoses must appear in programs or public policies by municipal and state managers. Surgical sterilization is the main measure for this control. The contraceptive drugs mainly injectables to prevent or slow down the heat or oestrus and not allow future fertility, were widely used in the 80s and early 90s and continues to this day. The objective of this study is to analyze the prevalence and the main implications associated with the use of contraceptives in dogs treated at University Veterinary Hospital "Veterinarian Jeremiah Pereira da Silva" the Federal University of Piauí, from January 2012 to July 2014, where it could be concluded that the use of contraceptives is possibly related to the high incidence of cases of pyometra, breast cancer and abortion.

RESUMO. Sabe-se que a casuística de gatos que apresentam sinais clínicos referentes ao trato urinário inferior (STUI) no mundo inteiro é enorme. Mas, reconhece-se também que, na maioria desses casos, não se conhece a causa específica que desencadeia tais sinais, assim como, sinais referentes a outros sistemas que por ventura venham a ser acometidos anteriormente ou concomitantemente aos STUI. O objetivo desse trabalho é investigar quais as evidências existentes atualmente sobre a cistite idiopática/intersticial felina (CIF) e como que se dá a abordagem do paciente felino para essa síndrome: quais perguntas devem ser feitas ao tutor, os achados dos exames físico e complementar, bem como os tratamentos mais indicados em cada caso em particular.Palavras chave: hematúria, gato, polaquiúria síndrome, stui Diagnosing feline idiopathic cystitis: ReviewABSTRACT. It is know that the casuistic of cats that present clinical signs referring to the lower urinary tract (STUI) worldwide is enormous. However it is also recognized that, in most of these cases, the specific cause that triggers such signals is not known, as well as signals referring to other systems that may be previously or simultaneously concomitant with STUI. The objective of this work is to investigate the current evidence on feline idiopathic / interstitial cystitis (CIF) and how to approach the feline patient for this syndrome: what questions should be asked to the tutor, the findings of the physical and complementary exams, as well as the treatments most indicated in each particular case.Keywords: hematuria, cat, polaquiuria, syndrome, luts Diagnosticando la cistitis idiopática felina: Revisión RESUMEN.

A captura, imobilização ou anestesia segura e efetiva de animais selvagens, como os macacos pregos (Sapajus libidinosus), geralmente é necessária para pesquisa e manejo, como também procedimentos cirúrgicos e diagnósticos, e dentre as espécies neotropicais, é a que apresenta maior distribuição geográfica. O gênero vem sendo utilizado em diversas pesquisas, dada a sua proximidade filogenética com a espécie humana, servindo de modelo biológico em experimentos aplicados a essa espécie. Há uma variedade de protocolos anestésicos utilizados para que a captura e o manuseio de macacos pregos seja realizada de modo simples e seguro. O objetivo deste trabalho é relatar a utilização da associação de dexmedetomidina, cetamina, morfina e midazolam para a contenção química de oito macacos-prego adultos, submetidos a dois procedimentos cirúrgicos, vasectomia nos machos e laqueadura das trompas eletivas nas femêas, tendo como meta estabelecer um protocolo de imobilização e contenção química segura e eficaz para a espécie. Durante os procedimentos cirúrgicos foram monitorados os parâmetros fisiológicos de frequência cardíaca, frequência respiratória, oximetria de pulso e temperatura retal de oito macacos prego. Ao término das cirurgias, os animais receberam atipamezole por via intramuscular. O protocolo utilizado demonstrou-se seguro e eficaz para contenção química de macacosprego submetidos a procedimentos cirúrgicos distintos permitindo reversão dos efeitos farmacológicos ao término da cirurgia.

One herein reports a successful case of celiotomy by plastrotomy for removal of foreign bodies in yellow-footed tortoise (Geochelone denticulata). The animal was treated at the Veterinary Hospital of the Federal University of Piaui, with appetite loss, regurgitation, constipation, lethargy, reluctance to walk and slightly reddish ocular mucous membranes. Radiographic examination was performed, confirming the presence of foreign bodies in the stomach. The tortoise underwent celiotomy by plastrotomy for the removal of the foreign bodies. The opening of the plastron was performed through the abdominal shields, with the aid of a circular mini grinding saw. One performed an incision in the midline between the two abdominal veins to access the abdominal cavity. A gastrotomy for removal of the foreign bodies (nails, toothpicks, stones, pieces of plastic, glass and crockery pieces) was performed after the location of the stomach. The surgery was successful and confirmed with radiographic evaluation in the immediate postoperative period. The celiotomy by plastrotomy for removal of foreign bodies in that animal proved to be a viable, very important and safe technique to the survival of chelonians.

Background: Vascular ring anomalies were congenital malformation of the great vessels, caused by defects in embryogenesis of the aortic arches. In dogs the most common type is persistent right aortic arch (PRAA). The PRAA occurs when the fourth right aortic arch persists instead of left to form the aorta. This malformation causes extraluminal compression of the esophagus up to the base of the heart. The constriction leads to esophageal dilatation secondary, located cranial to the base heart. The food, which can not progress beyond the narrowing, is regurgitated intermittently. Thus, the main clinical sign of disease is regurgitation when the patient starts eating solid foods. Respiratory clinical signs (mainly pneumonia by aspiration) may occur and can complicate the disease. The diagnosis is suspected by history (puppies at weaning) and physical examination. The diagnosis is confirmed by the esophagogram, where the image is characteristic (esophagic dilatation cranial base of the heart). The treatment of the affection is surgical, with transection and ligature of the vascular ring, viewed during thoracotomy by fourth intercostal space. The postoperative management which consists mainly of liquid diet and/or pasty is important for total recovery of the animal. In some cases, the animal must receive a special diet for life to prevent regurgitation. However at long term, most operated animal presents important sequels. These sequelae include respiratory disorders and low development of animal. The objective of the present paper is to relate a case of bitch with persistent right aortic arch, successful treated surgically, without serious clinical consequences. Case: A mongrel bitch with 2 months of age was attended at the Veterinary Hospital of the Federal University of the Piauí, Brazil, with vomiting. At the clinical examination was observed increase in volume in the cervical region. Radiographic examination revealed dilatation cranial to the heart base, characterizing megaesohagus. The diagnosis was PRAA. The dog was submitted at thoracotomy by fourth right intercostal space. The ligamentum arteriosum was localized and ligated at the distal and craniallly. During transoperative was made blood transfusion for correction of the anemia detected in preoperative period. The chest wall was closed routinely. Two days after surgery the dog was discharged. The postoperative diet consisted of liquids for a week, followed by semi-solid food always in bipedal position. After discharge, the owner returned for monthly visits for a year, with completion of physical examination and radiographs. Discussion: PRAA is most common in purebred dog, but in this case the animal is a mixed breed dog. The diagnosis was suspected due to history, and confirmed by esophagogram, where there was megaesophagus cranial to the heart base, according by literature. The surgical treatment, rapidly decided, and the absence of pneumonia, which is the main complication postsurgical, contributed to the observed good results. The blood transfusion to cor...
