Critérios e metodologias para produzir sêmen de caprinos e ovinos em nível de fazenda / The criteria and methodologies used to produce ram and goat semen on the farm

A criopreservação de sêmen é uma importante estratégia para o armazenamento de material genético de reprodutores ovinos e caprinos, considerados superiores do ponto de vista fenotípico, mas especialmente, pelos seus méritos genéticos. Hoje no Brasil apenas uma central regulamentada pelo MAPA está ema atividade, o que significa que existe pouca dose de sêmen comercial à disposição para programas de melhoramento genético. Programas de banco de sêmen podem ser realizado nas fazendas, entretanto, tem seu uso limitado a propriedade onde está o reprodutor. Neste caso, apesar de maiores limitações de estrutura e equipamentos para a execução do serviço, o domínio das variações da técnica de congelação de sêmen e o cuidado com as questões sanitárias dos reprodutores possibilitará ao Médico-Veterinário a execução do serviço com níveis adequados de segurança e qualidade das doses de sêmen produzidas. O objetivo deste estudo é apresentar e discutir critérios e metodologias para congelação de sêmen de pequenos ruminantes em diferentes condições, fruto de diversas experiências e trabalhos desenvolvidos por nosso grupo e outros, nos últimos vinte anos, e que tem possibilitado resultados satisfatórios.(AU

Sperm cryopreservation is an important strategy for the storage of genetic material from ovine and goat breeders, considered superior from the phenotypic point of view, but especially for their genetic merits. Today in Brazil only one center regulated by the Ministry of Agriculture, Livestock and Supply is in operation, which means that there is little dose of commercial semen available for genetic improvement programs. Semen bank programs can be carried out on farms; however, their use is limited to the property where the breeder is located. In this case, despite greater limitations of structure and equipment for the execution of the service, mastering variations in the semen freezing technique and taking care of the health issues of the breeders will enable the Veterinarian to perform the service with adequate levels of safety and quality of semen doses produced. This study aims to present and discuss criteria and methodologies for freezing semen from small ruminants under different conditions, the result of several experiences and works carried out by our group and others, in the last twenty years, which have enabled satisfactory results.(AU))

Use of smartphone messaging applications to increase diagnostic efficiency in veterinary diagnostic laboratories / Uso de aplicativos de mensagens de smartphones para aumentar a eficiência diagnóstica em laboratórios de diagnóstico veterinário

Many inconclusive diagnoses have been reported in studies carried out in veterinary diagnostic laboratories (VDLs). These inconclusive diagnoses are often associated with field veterinarians sending tissue samples and carcasses for histopathological examination. The use of social media in care has the potential as a tool for improvements in animal health. We evaluated the improvement in the rate of conclusive diagnoses in the VDL when using a messaging application for smartphones as a guidance tool for field veterinarians to refer animals and sample tissues for necropsy and histopathology. Veterinarians contacted the VDL team via a messaging app and forwarded videos, images, and clinical-epidemiological history. Based on this information, guidelines were created in real-time for contacting professionals about methods for collecting samples during necropsy and making diagnoses and scheduling visits to properties. The data obtained showed that smartphone messaging applications could be useful tools to expand the performance of VDLs and improve their diagnostic efficiency, especially when sending samples of animals that died is impossible due to certain sanitary conditions.

Muitos diagnósticos inconclusivos têm sido relatados em estudos realizados em laboratórios de diagnóstico veterinário (LDVs). Esses diagnósticos inconclusivos são frequentemente associados a veterinários de campo que enviam amostras de tecidos e carcaças para exame histopatológico. O uso das mídias sociais com cuidado tem potencial como ferramenta para melhorias na saúde animal. Avaliamos a melhora na taxa de diagnósticos conclusivos no LDV ao utilizar um aplicativo de mensagens para smartphones como ferramenta de orientação para veterinários de campo encaminharem animais e amostras de tecidos para necropsia e histopatologia. Os veterinários entraram em contato com a equipe do L por meio de um aplicativo de mensagens e encaminharam vídeos, imagens e histórico clínico-epidemiológico. Com base nessas informações, foram criadas orientações em tempo real para contato dos profissionais sobre métodos de coleta de amostras durante a necropsia e realização de diagnósticos, além do agendamento de visitas às propriedades. Os dados obtidos mostraram que os aplicativos de mensagens para smartphones podem ser ferramentas úteis para ampliar o desempenho dos VDLs e melhorar sua eficiência diagnóstica, principalmente quando o envio de amostras de animais que morreram é impossível devido a determinadas condições sanitárias.

Cutaneous myxoma in broiler chicken detected during slaughtering

Background: A cutaneous or superficial myxoma is a benign neoplasm of dermal or subcutaneous fibroblast origin. Although rare, it has been previously described in several species, including poultry. It presents as a single node or soft mass with a gelatinous cut surface. Histopathological analysis is essential for diagnosis and to differentiate it from other mesenchymal neoplasms and inflammatory or degenerative processes. Microscopically, it consists of dermal or subcutaneous lobules of plump, stellate, or spindle-shaped, bland-looking cells embedded in a basophilic myxoid matrix. This report describes the pathological findings in a rare case of cutaneous myxoma in a 42-day-old broiler flock. Cases: During ante mortem inspection of a 42-day-old broiler flock at a slaughterhouse under the authority of the Federal Inspection Service (southern Brazil), nodular lesions or encrusted areas with yellow and black areas were observed in the head skin of less than 1% of animals. These lesions, approximately 0.5 cm in diameter, were observed on the comb, in the periocular skin region, and close to the animals' nostrils. During the breeding period, no health or epidemiological events were observed. Fragments of the lesions in the comb and periocular skin were collected and fixed in buffered 10% formalin. The samples were sent to the laboratory, routinely processed, and stained with hematoxylin and eosin and Alcian blue. Microscopically, the lesions consisted of irregular multifocal proliferation of connective tissue showing spindle cells with poorly demarcated borders and scarce cytoplasm in a slightly basophilic myxoid aspect matrix. The adjacent epidermis is compressed due to neoplastic proliferation. No areas of epithelial hyperplasia or inclusion bodies were observed. According to the pathologic description and considering its descriptive epidemiology, our main clinical suspicion was cutaneous fowl pox, a pathology characterized by the appearance of nodules in regions devoid of feathers. However, the microscopic changes observed were compatible with those described for cutaneous myxomas. In addition, the extracellular matrix was positive for Alcian Blue staining, which is an indicator of myxoma. In the present case, the SIF did not report the same macroscopic lesions in other flocks of the same origin. Discussion: Connective tissue tumors, including myxomas, occur considerably less frequently under field conditions. In addition, these neoplasms are more frequent in mature birds and are not usually described in broilers, as observed in this report. The cutaneous myxoma described in broilers is usually a sporadic neoplasm that does not cause zootechnical losses, as observed in the case report. Its etiology is unknown and has been associated with various factors, such as local trauma and foreign bodies. Some fragments of plant material from the breeding environment were microscopically detected in the encrusted areas, which may indicate previous trauma or a foreign body. Myxoma has been associated with avian leukosis virus (ALV) subgroup A, but SIF did not report the same macroscopic lesions in other flocks of the same breeder hen's origin in the present case. Furthermore, sporadic connective tissue tumors associated with the virus occur in mature chickens but not in broilers. Myxoma lesions should be considered in the differential diagnosis of other connective tissue tumors and infectious agents that cause lesions in the skin and subcutaneous tissue.

Adenocarcinoma pancreático em um gato / Pancreatic adenocarcinoma in a cat

Background: Despite being rare in domestic animals, pancreatic adenocarcinoma is the most common malignant tumor of the feline pancreas. Due non-specificity of clinical signs in cats and the late diagnosis of the neoplasm, it is necessary to understand this disease better, to contribute for the knowledge of its early recognition and treatment. Thus, this study aims to report a case of metastatic pancreatic ductal adenocarcinoma in a cat, focusing on the main clinical aspects, diagnosis, and prognosis of this disease, in addition to the description of the presentation of peritoneal carcinomatosis. Case: A 14-year-old male neutered mixed breed cat, was referred to the Feline Medicine Service (MedFel) of the Hospital de Clínicas Veterinárias (HCV) - Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre, RS, with a history of hyporexia, constipation and increased abdominal volume for 3 days, besides mild difficulty in locomotion and progressive weight loss in the last 6 months. On the physical examination, the patient was alert, with a body condition score of 6/9; muscle condition score 1/4 and moderate dehydration of 7%. Popliteal lymph nodes were enlarged, and abdominal distension was evident. Around 200 mL of a slightly cloudy, straw-yellow liquid were drained from the abdominal cavity. After draining the fluid, a new abdominal palpation was performed, and there were fecal retention and a palpable mass in the right hypogastric region. The result of the cytological analysis of the fluid was consistent with a protein-rich transudate, suggesting neoplastic effusion of epithelial origin. Hematological and biochemical changes included leukocytosis due to neutrophilia, monocytosis, lymphopenia, thrombocytosis and azotemia. On abdominal ultrasound, the patient had free fluid in the abdominal cavity, and the gallbladder had discreet of biliary sludge. The intestines showed some corrugated segments with other segments lacking definition of its layers, and without peristaltic movements, suggesting intestinal neoplasia. Pancreas and adrenals were not visualized. On the chest X-ray, moderate opacification of lung fields with a diffuse interstitial pattern was observed, suggesting lung metastasis. The patient presented an acute worsening of the clinical condition and the owner requested euthanasia. The patient was referred for necropsy and based on the macroscopic and microscopic changes, the post-mortem diagnosis was metastatic pancreatic ductal adenocarcinoma with peritoneal carcinomatosis. Discussion: The clinical presentation of cats with exocrine pancreatic neoplasia is nonspecific, as clinical signs are common to several diseases, such as anorexia, vomiting, abdominal pain, weight loss with normal appetite, jaundice, depression, and lethargy. Complementary blood tests also do not provide data that could lead to the suspicion of pancreatic neoplastic disease. In the present case, the diagnosis of metastatic pancreatic ductal adenocarcinoma with peritoneal carcinomatosis was only possible post mortem. The pancreas is a difficult organ to assess adequately using most diagnostic imaging methods, so histopathology is still the method of choice for differentiating pancreatic tissue comorbidities. Therefore, exploratory laparotomy should be instituted to provide tissue samples from the pancreas and its metastases for histopathological diagnosis, whenever ultrasound or other imaging methods indicate suspicious abdominal changes. The literature reports that less than 10% of affected cats treated with complete surgical removal of the mass and chemotherapy alone will survive more than a year, and the average time for untreated cats is only 6 days. The prognosis of this disease is bad and most cats are euthanized, due to rapid clinical worsening. Therefore, diagnosis is essential to determine an adequate prognosis in advanced cases and to support therapeutic decisions or euthanasia.

Retinopatia deficiente de taurina em uma gata / Taurine deficiency retinopathy in a cat

Background: Taurine is an essential amino acid for cats and its deficiency causes an ocular disorder called taurine deficiency retinopathy. The retinal lesion is definitive and can be classified into five progression stages. In an advanced stage, it leads to blindness that in most cases is irreversible. This disease is considered rare as taurine is currently supplemented in commercial cat food. The objective of this report is to describe the ophthalmic changes in a cat with advanced taurine deficiency retinopathy, a rare but current disease that is important for differential diagnosis of blindness in cats. Case: We report the case of an adult mixed-breed cat (weighing 3.4 kg), that was attended by the Ophthalmology Service of the College of Veterinary Medicine and Animal Science (UNESP - Botucatu), which was treated due to complaints of poor visual acuity for about 1 year. The animal, which was previously a stray animal, had been adopted for 2 years and provided premium cat food ad libitum. Ophthalmic examination showed bilateral mydriasis, with negative menace, direct pupillary, and consensual light reflexes. No change was observed in the ocular appendages, cornea, anterior chamber, lens, and vitreous humor. The eyes were normotensive and fluorescein test negative. Direct and indirect fundoscopy revealed an area of ellipsoidal hyperreflexia with darkened margins laterally to the optic nerve disk in the tapetal region and intense retinal vascular attenuation in both eyes, with a diagnosis of taurine deficiency retinopathy. Complete blood count and biochemical analysis parameters were within the normal range, including the leukocyte count. The guardian was instructed to continue feeding the cat balanced cat food and received information on the proper care and management of a blind animal. Discussion: Although taurine deficient retinopathy is currently underdiagnosed due to the supplementation of this amino acid in commercial cat food, animals that are not properly fed, such as those receiving dog food or homemade food, may be deficient in this amino acid. Taurine deficiency and in this case, the consequent taurine deficiency retinopathy, was diagnosed by visualizing the lesion characteristic of this amino acid deficit since no other retinal change presents this aspect in cats. Therefore, this lesion is considered pathognomonic of this deficiency. Hyperreflective retinal lesions with darkened margins indicate the slow chronic progression in the already stabilized lesions. The animal in this report presented pigmented lesion margins, indicating the chronicity of these retinal changes. Moreover, lesion signs are visible on fundoscopy only after a period of 2-11 months of nutritional amino acid deficiency, and complete retinal atrophy usually occurs after at least nine months of taurine deficiency. Thus, complete blindness associated with advanced retinal changes reinforced the suspicion that the animal had taurine deficiency for a prolonged period of time prior to its adoption. Its guardian was instructed to provide balanced commercial cat food, because although retinal lesions are irreversible, cardiac changes resulting from taurine deficiency are reversed with dietary supplementation. In addition, taurine deficiency affects other organs and systems, such as the central nervous, immune, and reproductive systems. In conclusion, although taurine deficiency retinopathy is currently rare, this condition should be considered one of the possible differential diagnoses for blindness in feline patients.

Análise da correlação dos índices de estrutura e recursos humanos do serviço veterinário oficial em 2019 e as incidências acumuladas (2017 ­ 2019) de doenças de notificação obrigatória em bovinos e equinos no Brasil / Analysis of the correlation between the structure and human resources indexes of the official veterinary service in 2019 and the accumulated incidences (2017 ­ 2019) of notifiable diseases in cattle and horses in Brazil

As doenças de notificação obrigatória em bovinos podem gerar impactos sociais e econômicos significativos na cadeia pecuária brasileira, além de consequências negativas no mercado internacional devido a embargos sanitários. Para auxiliar no entendimento de como um sistema de vigilância epidemiológica com mais recursos pode gerar mais credibilidade para o país, foram realizadas análises de correlação entre a notificação de doenças e a estrutura veterinária disponível nos Órgãos Executores de Sanidade Agropecuária (OESAs), a partir dos dados contidos no Sistema Nacional de Informação Zoossanitária (SIZ), entre os anos de 2017 e 2019. Com base nos dados do serviço veterinário, foram produzidos o Índice de Estrutura Física Oficial (IEFO) e o Índice de Recursos Humanos do Serviço Oficial (IRHSO). Foi realizada análise de correlação entre a notificação de doenças de bovinos com a capacidade de estrutura física e recursos humanos de vigilância epidemiológica disponíveis no Serviço Veterinário brasileiro. Os estados AP, RR e SC foram os que mais notificaram brucelose e tuberculose no período e estão entre os melhores índices de estrutura e recursos humanos do país. A análise dos índices mostrou que a raiva não possui correlação significativa com estrutura e recursos humanos do serviço, entretanto, brucelose e tuberculose possuem correlação positiva com estrutura veterinária oficial disponível para a vigilância em bovinos. Portanto, melhorias na estrutura podem refletir no incremento dos índices de notificação das doenças de bovinos, assim como na qualidade de suas informações.

Notifiable diseases in cattle can generate significant social and economic impacts on the Brazilian livestock chain, in addition to impacts on the international market due to sanitary embargoes. To help understand how an epidemiological surveillance system with more resources can generate more credibility for the country, correlation analyzes were carried out between the notification of diseases and the veterinary structure available in the Executing Bodies of Agricultural Health (OESAs), based on the data contained in the National System of Zoosanitary Information (SIZ), between the years 2017 to 2019. Based on public data from the veterinary service, the Official Physical Structure Index (IEFO) and the Official Service Human Resources Index (IRHSO) were produced. Correlation analysis was performed between the notification of bovine diseases with the capacity of physical structure and human resources for epidemiological surveillance available in the Brazilian Veterinary Service. AP, RR and SC were the states that most notified brucellosis and tuberculosis in the period and are among the best indices of structure and human resources in the country. The analysis of correlation indices showed that the rabies disease does not have a significant correlation with the structure and the human resources of the service, however, brucellosis and tuberculosis does have a positive correlation with the official veterinary structure available for surveillance in cattle. Therefore, Improvements in the structure can reflect in the increase of the notification rates, as well as in the quality of its information.

Desenvolvimento de plataforma informatizada para o gerenciamento da inspeção e análise laboratorial de produtos de origem animal fornecidos ao exército brasileiro / Development of a computerized platform for inspection management and laboratory analysis of animal products supplied to the Brazilian army

O trabalho propôs o desenvolvimento de plataforma informatizada para apoio ao gerenciamento da inspeção e análise laboratorial de produtos de origem animal fornecidos à tropa do Exército Brasileiro. A pesquisa aplicada corresponde à modalidade de produção tecnológica, em três fases. A fase I foi realizada por meio do levantamento dos arquivos de Laudos Fiscais dos artigos de origem animal, impressos e emitidos pelo LIAB (Laboratório de Inspeção de Alimentos e Bromatologia) do 12º Batalhão de Suprimento, durante o período de janeiro a novembro de 2021, e dos arquivos referentes aos Boletins Técnicos do Exército Brasileiro (BT30.404- EB). A fase II correspondeu ao projeto e desenvolvimento da "Plataforma Alimentar - Rastreabilidade e Confiabilidade Garantida". Toda a programação desenvolvida foi armazenada em um servidor web terceirizado e pode ser acessada pelos LIABs pelo link: www.pmppa.com.br/alimentar. A plataforma informatizada utilizou a linguagem PHP (Hypertext Preprocessor) associada às linguagens CSS (Cascading Style Sheet), HTML (Hyper Text Markup Language), JS (Java script) e bootstrap. A fase III consistiu na realização do teste de Caixa Preta. Os módulos disponíveis para inclusão das informações no sistema são: "cadastro dos artigos de origem animal"; "lançamento das análises"; "cadastro de Boletim Técnico" e "relatórios", os quais permitem atribuir ao artigo de origem animal a qualidade satisfatória ou insatisfatória para o consumo seguro da tropa, de acordo com a avaliação laboratorial das amostras. Houve, com eficácia, o desenvolvimento da plataforma, garantindo ao oficial médico veterinário uma ferramenta segura para apoio ao gerenciamento de qualidade dos produtos destinados à alimentação da tropa do Exército Brasileiro.

The study proposed the development of a computerized platform to support the inspection management and laboratory analysis of animal products supplied to the Brazilian Army troops. The applied research corresponds to the modality of technological production in three phases. Phase I consisted in survey from Fiscal Report Files of animal products, which was printed and issued by the FIBL (Food Inspection and Bromatology Laboratory) from the 12th Supply Battalion, from January to November 2021, and the Brazilian Army's Technical Bulletins (BT30.404-EB) Files. Phase II corresponded to design and development of the "Food Platform - Guaranteed Traceability and Reliability". All the developed programming stored at an outsourced web server by accessing the FIBLS through the link: www.pmppa.com.br/alimentar. The supportive computerized platform used the PHP (Hypertext Preprocessor) language associated with the CSS (Cascading Style Sheet), HTML (Hyper Text Markup Language), JS (Java script) and bootstrap. Phase III consisted in performing a Black Box testing. The available modules for information inclusion in the system are the following issues: "Animal products registration"; "Analyses release"; "Technical Bulletin registration" and "Reports", which allow attributing the satisfactory or unsatisfactory quality to the animal products providing safe consumption for the troops, according to the evaluation of laboratory samples. The platform was effectively developed, guaranteeing the veterinary officer a safe tool to support the quality management of products intended for feeding the Brazilian Army troops.

Background: There is no hope of preserving vision at the terminal stage of glaucoma, and surgical treatment is indicated in thesecases. Among the various surgical techniques used, eye evisceration with implantation of an intrascleral prosthesis provide thebest cosmetic results. Even though eye evisceration with prosthesis implantation represents an excellent treatment option forterminal glaucoma, reports on the use of this technique in dogs are scarce in the current literature. The aim of this work is to reporta case of a dog with end-stage glaucoma subjected to eye evisceration surgery and implantation of an intrascleral prosthesis.Case: A 7-year-old bitch mixed breed with a history of glaucoma secondary to uveitis with no response to medical therapy wasreferred to the Ophthalmology service of the University Veterinary Hospital of Coimbra (HVUC), Portugal At the ophthalmicexamination, the glaucomatous left eye was buphthalmic, with congested episcleral blood vessels, mydriasis, and posterior luxation of the lens; there was no response to threat or obfuscation, no direct and consensual pupillary reflex, nor pupillary reflexesto chromatic light.

Levantamento de dados de condenações pulmonares por aspiração de sangue em abate de suínos sob o Serviço de Inspeção Estadual da Bahia entre os anos de 2018 a 2020 / Data Survey on pulmonary condemnatios for blood aspiration in swine slaughter under the Bahia State, Brazil Inspection Service from 2018 to 2020

O presente estudo tem como objetivo descrever os dados das condenações de pulmões por aspiração de sangue em abate de suínos do estado da Bahia, no período de janeiro de 2018 a outubro de 2020, em abatedouros sob fiscalização do Serviço de Inspeção Estadual (SIE). A coleta retrospectiva foi facilitada pela Agência de Defesa Agropecuária da Bahia (ADAB), através da Guia de Trânsito Animal (GTA), e foram coletados dados de 255.834 suínos abatidos em matadouros frigoríficos, localizados em oito municípios. Nos anos de 2018 e 2019, a aspiração de sangue foi a lesão mais encontrada. Em 2018, foram 15,45% (1131/7322) das alterações macroscópicas e 36,48% (1131/3100) das condenações pulmonares, e em 2019, foram 14,75% (1053/7138) e 36,20% (1053/2909), respectivamente. A congestão foi a lesão mais encontrada em 2020, mas não houve diferença considerável com a aspiração de sangue, que foi destaque das condenações pulmonares, com 38,07% (712/1870). Estes dados revelam a frequência de condenação por aspiração de sangue no estado da Bahia e sugerem implementação de treinamentos de manejo não violento para os funcionários dos abatedouros frigoríficos, visto que esse tipo de lesão indica estresse e uma tecnopatia associada à falha na insensibilização e sangria, em razão do animal agonizar enquanto tenta respirar após a incisão no pescoço.

This study aims to analyze data on lung condemnations for blood aspiration in pig slaughter in the state of Bahia, Brazil from january 2018 to october 2020, in slaughterhouses under supervision of the State Inspection Service (SIE). The retrospective collection was facilitated by the Agricultural Defense Agency of Bahia (ADAB), through the Animal Transit Guide (GTA), and data were collected from 255,834 pigs slaughtered in slaughter houses located in eight municipalities. In 2018 and 2019, blood aspiration was the most common lesion. In 2018, it was 15,45% (1131/7322) of macroscopic changes and 36,48% (1131/3100) of lung condemnations, and in 2019, it was 14,75% (1053/7138) and 36,20% (1053/2909), respectively. Congestion was the most common lesion found in 2020, but there was no considerable difference with blood aspiration, which was highlighted in pulmonary condemnations, with 38,07% (712/1870). These data reveal the frequency of condemnations for blood aspiration in the state of Bahia, Brazil and suggest the implementation of training in non-violent management for employees of slaughterhouses, as this type of injury indicates stress and a technopathy as sociated with failure in stunning and bleeding, because the animal agonizes while trying to breathe after the neck incision

Osteoma in Agapornis roseicollis / Osteoma em Agapornis roseicollis

Neoplasias are important causes of illness and death in domestic animals. However, in birds, they are less frequent compared with other species such as dogs and cats. Moreover, benign tumors of bone are even less frequent in captive birds being considered sporadic, which make it a poorly understood entity due to the lack of clinical and histopathological data. Thus, we present a case of an osteoma in a Peach-faced lovebird (Agapornis roseicollis) approaching clinical and morphological aspects. A two-years-old lovebird was referred to the veterinary hospital with a 4-month evolution round to oval tumoral mass on the wing. The nodule was firm, painful when manipulated. Radiographic examination revealed a radiopaque mass in the radius and ulna bones. The animal has died during the surgical procedures. The affected wing was submitted to pathology service and histopathology revealed an osteoma.

As neoplasias são importantes causas de doença e morte em animais domésticos. No entanto, em aves, são menos frequentes em comparação com outras espécies, como cães e gatos. Além disso, tumores ósseos benignos são ainda menos frequentes em aves de cativeiro sendo considerados esporádicos, o que o torna uma entidade pouco compreendida devido à falta de dados clínicos e histopatológicos. Assim, apresentamos um caso de osteoma em Periquito cara-de-pêssego (Agapornis roseicollis) abordando aspectos clínicos e morfológicos. Um periquito de dois anos foi encaminhado ao hospital veterinário com uma massa tumoral ovalada na asa com evolução de 4 meses. O nódulo era firme, doloroso quando manipulado. O exame radiográfico revelou uma massa radiopaca nos ossos rádio e ulna. O animal morreu durante os procedimentos cirúrgicos. A asa afetada foi submetida ao serviço de patologia e a histopatologia revelou um osteoma.

Demographics and health care profiles of dogs and cats associated with the socioeconomic profile of their tutors in areas assisted by Family Health Strategies in Brazil / Perfis demográficos e assistenciais de cães e gatos associados ao perfil socioeconômico de seus tutores em áreas atendidas por Estratégias de Saúde da Família no Brasil

This study aimed to evaluate the demographic and healthcare situation of dogs and cats owned by families assisted by the Family Health Strategy (FHS), from Santa Maria/RS, Brazil. This research was a cross-sectional and population-based study developed by applying a questionnaire to residents in the 16 FHS areas of the city. This was the first study addressing pet animal conditions in the FHS area. A total of 414 households were studied, and 88.5% of them had pets (dogs and/or cats), with an average of 2.2 dogs and 0.8 cats per household. Only 18.4% (228/1.241) of the animals were sterilized (dogs, 15.1% [135/891]; cats, 26.7% [93/348]). When considering the number of dogs, households with one resident had fewer dogs than households with two or more residents (p=0.006). The level of education and family income were not associated with the number of animals (p>0.001). However, higher levels of education and family income were associated with the sterilization of dogs, veterinary monitoring, vaccination, and treatment of ectoparasites in dogs and cats (p<0.0001). Additionally, the higher family income was associated with a higher frequency of endoparasite treatment (p<0.05). The study shows a high average number of pets per household in FSH areas compared to the average household population as well as a lack of veterinary care, making it essential to promote responsible custody.

Este estudo teve como objetivo avaliar a situação demográfica e de saúde de cães e gatos pertencentes a famílias assistidas pela Estratégia de Saúde da Família (ESF), de Santa Maria/RS, Brasil. Esta pesquisa foi um estudo transversal baseado na população adscrita, desenvolvido por meio da aplicação de questionário aos residentes das 16 áreas de ESF da cidade. Este foi o primeiro estudo que abordou as condições dos animais de estimação na área de ESF. Foram estudados 414 domicílios, e 88,5% deles tinham animais de estimação (cães e/ou gatos), com uma média de 2,2 cães e 0,8 gatos por domicilio. Apenas 18,4% (228/1,241) dos animais foram esterilizados (cães, 15,1% [135/891]; gatos, 26,7% [93/348]). Ao considerar o número de cães, os lares com um residente tinham menos cães que os lares com dois ou mais residentes (p=0,006). O nível de educação e a renda familiar não estavam associados ao número de animais (p>0,001). Entretanto, níveis mais altos de educação e renda familiar foram associados com a esterilização de cães, monitoramento veterinário, vacinação e tratamento de ectoparasitas em cães e gatos (p<0,0001). Adicionalmente, a maior renda familiar foi associada a uma maior freqüência de tratamento endoparasitário (p<0,05). O estudo mostra um alto número médio de animais de estimação por domicílio nas áreas de ESF em comparação com a população domiciliar média, bem como uma falta de cuidados veterinários, tornando essencial promover a custódia responsável.

Estação do ano ao parto e o desempenho reprodutivo de vacas leiteiras mestiças / Season of the year at calving and reproductive performance of crossbred dairy cows

O objetivo deste trabalho foi avaliar os efeitos da estação do ano ao parto sobre a taxa de concepção à primeira inseminação pós-parto e o intervalo parto-concepção de vacas leiteiras mestiças. O estudo foi conduzido em sete fazendas localizadas em Ituiutaba/MG. O manejo reprodutivo foi realizado a cada 30 dias para avaliação ginecológica e diagnóstico de gestação. Na primeira cobertura pós-parto, as vacas detectadas em estro eram submetidas à inseminação artificial (IA) 12 horas após a detecção ou colocadas com touro (monta controlada ­ MC). As vacas não detectadas em estro até os 60 dias pós-parto eram submetidas à inseminação em tempo fixo (IATF). Os serviços subsequentes seguiam os critérios de cada fazenda. Foram avaliados 841 partos de 581 vacas ocorridos de janeiro de 2011 a junho de 2014. Os dados foram analisados pelo PROC GLIMMIX do SAS (p<0,05), sendo incluídos no modelo a fazenda, a estação do ano ao parto, o tipo da primeira inseminação pós-parto e possíveis interações. As vacas que receberam MC apresentaram taxa de concepção à primeira IA pós-parto maior do que as vacas submetidas à IA convencional e à IATF (p<0,001). Não foi detectada interação entre o tipo de serviço e a estação do ano ao parto (p=0,2989) na taxa de concepção. A estação do ano ao parto não interferiu na taxa de concepção à primeira IA pós-parto de vacas leiteiras mestiças (p=0,36). No entanto, vacas que pariram na primavera-verão tiveram esse intervalo maior em relação às que pariram no outono-inverno (p=0,0044). Desta forma, concluiu-se que vacas leiteiras mestiças cujos partos ocorrem nas estações mais quentes e úmidas do ano apresentam um comprometimento da eficiência reprodutiva subsequente.

The study aimed to evaluate the effects of the season of the year at calving on the conception rate at the first insemination post-partum and the calving-conception interval of crossbred dairy cows. The study was conducted on seven farms located in Ituiutaba/MG. The reproductive management was performed every 30 days for gynecologic evaluation and pregnancy diagnostic. At the first post-partum service, cows detected in estrus were submitted to artificial insemination (AI) 12 hours after estrus detection or bred by the sire (controlled breeding ­ CB). Cows that were not detected in estrus until 60 days after calving were submitted to timed artificial insemination (TAI). The subsequent services followed the criteria of each farm. A total of 841 parturitions from 581 cows occurred from January 2011 to June 2014 were evaluated. Data were analyzed by PROC GLIMMIX of SAS (p<0.05), including the farm, the season of the year at calving, the type of the first insemination post-partum and, possible interactions in the model. Cows submitted to CB presented a higher conception rate at first insemination post-partum than cows submitted to conventional AI and TAI (p<0.001). There was no interaction between the service type and the season of the year at calving (p=0.2989) on the conception rate. The season of the year at calving did not influence the conception rate at first insemination post-partum of crossbred dairy cows (p=0.36). However, cows that calved during spring-summer had a prolonged interval in relation to cows that calved during autumn-winter (p=0.0044). In conclusion, crossbred dairy cows whose calving occurs in the hottest and wettest seasons of the year show a subsequent impairment of their reproductive performance.

Risk of arrhythmias in dogs with structural heart disease / Potencial arrítmico de cardiopatias em cães

Presently, pet life expectancy is becoming longer and several diseases inherent to age have been diagnosed, with heart disease being a frequent finding. Although various heart diseases have different pathophysiologies, many morphological and hemodynamic changes can predispose patients to arrhythmias. The presence of arrhythmias can worsen the underlying heart disease and predispose patients to develop new alterations, making arrhythmia detection important for establishing adequate therapeutic protocols and a better prognosis. The present study aimed to determine the arrhythmias most frequently found in dogs treated at the Cardiology and Respiratory Diseases Service (SCDR) of the Small Animals Sector of the Veterinary Hospital of the Federal Rural University of Rio de Janeiro (UFRRJ), during the period from January to 2014 to December 2017, relating them to sex, age group, size, and the presence or absence of heart disease. A total of 586 medical records of dogs treated with SCDR-UFRRJ were retrospectively evaluated. Of these, 15.4% had arrhythmias, 95.6% had diagnoses of heart disease, 61.1% (55/90) were diagnosed with mitral valve disease, and 27.8% (25/90) had dilated cardiomyopathies. The most frequent rhythm disturbances were premature ventricular complexes associated with chronic degenerative mitral valve disease or dilated cardiomyopathy. Statistical analysis confirmed the risk of a cardiac patient developing rhythm or conduction alterations (OR, 4.46; p = 0.0003). In conclusion, the pathophysiology of heart failure can lead to the development of rhythm and conduction disorders.

Com a maior expectativa de vida dos animais de estimação, diversas enfermidades inerentes a idade têm sido diagnosticadas, sendo as cardiopatias um achado frequente. Apesar das diferentes cardiopatias terem fisiopatologias distintas, diversas alterações morfológicas e hemodinâmicas podem ocorrer predispondo ao aparecimento de arritmias. A presença de arritmias pode agravar a doença cardíaca de base e predispor ao desenvolvimento de novas alterações, tornando-se importante a sua detecção para instituição de protocolos terapêuticos adequados e melhor prognóstico da doença. O presente estudo teve como objetivo determinar as arritmias mais frequentemente encontradas em cães atendidos no Serviço de Cardiologia e Doenças Respiratórias (SCDR) do Setor de Pequenos Animais do Hospital Veterinário da Universidade Federal Rural do Rio de Janeiro (UFRRJ), no período de janeiro de 2014 a dezembro de 2017, relacionando-as com sexo, faixa etária, porte e presença ou não de cardiopatias. De maneira retrospectiva, foram avaliados 586 prontuários de cães atendidos no SCDR-UFRRJ. Destes, 15.4% apresentavam alguma arritmia e 95,6% apresentavam diagnostico de alguma cardiopatia, sendo 61.1% (55/90) diagnosticados com endocardiose de mitral e 27.8% (25/90) com cardiomiopatia dilatada. O distúrbio de ritmo mais frequente foram os complexos ventriculares prematuros associados a doença valvar degenerativa crônica de mitral ou a cardiomiopatia dilatada. Na análise estatística, o risco de um paciente cardiopata desenvolver alterações de ritmo ou de condução foi confirmado (OR: 4,46; p=0,0003). Conclui-se que a fisiopatologia da insuficiência cardíaca pode levar ao desenvolvimento de distúrbios de ritmo e também distúrbios de condução.

Segunda opinião diagnóstica na anatomia patológica / Second opinion on pathological anatomy

A anatomia patológica, veterinária e humana, no contexto mundial, adota, com cada vez mais frequência, a prática de segunda opinião diagnóstica, como método de verificação e confirmação de pareceres técnicos, objetivando uma maior acurácia e precisão dos diagnósticos fornecidos. Este trabalho tem por objetivo discorrer sobre a importância da segunda opinião diagnóstica na anatomia patológica e seus aspectos éticos. A segunda opinião reflete uma medida de precisão diagnóstica e, apesar de alguns sítios anatômicos ou áreas de subespecialidade apresentarem maiores frequências de grandes discordâncias diagnósticas, quase todas as áreas no âmbito da anatomia patológica podem ser clinicamente afetadas pela segunda opinião. Dadas as variações entre as instituições, recomenda-se a revisão de segunda opinião de todos os locais anatômicos em todas as instituições, públicas e privadas, para maximizar a descoberta de divergências clinicamente relevantes.

Human and veterinary medicine pathological Anatomy in the world context, increasingly adopts the practice of second diagnostic opinion, as a method of verification and confirmation of technical opinions, aiming at greater accuracy and precision of the diagnoses provided. This work aims to discuss the importance of the second diagnostic opinion in pathological anatomy and its ethical aspects. The second opinion reflects a measure of diagnostic accuracy, and although some anatomical sites or areas of subspecialty have higher frequencies of major diagnostic disagreements, almost all areas within the pathological anatomy can be clinically affected by the second opinion. Given the variations between institutions, a second opinion review of all anatomic sites in all institutions, public and private, is recommended to maximize the discovery of clinically relevant discrepancies.

Canine visceral leishmaniasis in Rio Grande do Norte state, Northeastern Brazil - spatial analysis

Background: Human visceral leishmaniasis (HVL) is a potentially fatal disease with a worldwide distribution, being endemic in 12 countries in the Americas. The main reservoir in the urban environment is the dog, whose cases precede the disease in humans. For the control of HVL, the Ministry of Health of Brazil recommends efficiency in the notification of human cases, control of sandflies, elimination of reservoirs and health education, in addition to the interruption in the transmission of the disease by the intensification of surveillance and control of priority areas based on identification by spatial analysis. The objective of the study was to investigate the spatial distribution of canine visceral leishmaniasis (CVL) in the state of Rio Grande do Norte, Brazil, determining areas of risk by identifying spatial clusters, with a view to monitoring and implementing preventive actions. Materials, Methods & Results: Secondary data from sample and/or routine serological surveys for serological diagnosis of LVC in the period from 2011 to 2018 were used. The inclusion of animals in the routine diagnosis per municipality resulted from demands of veterinarians, veterinary clinics, dog tutors, zoonoses control centers and environmental surveillance. The spatial statistical analysis was performed with SatScan software version 9.6 for the detection of spatial clusters, based on using the statistical scan method. Of the total of 231,123 dogs tested in the period, 24,642 (10.6%) were seroreactive for CVL. During the study, the municipalities with the highest number of cases were Natal and Mossoró, with 9,671 and 4,514 cases, respectively. During the years 2011 to 2018, 38 significant clusters (P < 0.05) were identified that included one or more municipalities. Discussion: The state of Rio Grande do Norte has an urban environment susceptible to the occurrence of CVL, with climate and topography that favor the proliferation of the vector and housing in precarious socio-sanitary conditions. The high number of CVL cases in Natal can be explained by the fact that the city is considered endemic for CVL, characterized as an area of intense transmission of the disease, according to the Ministry of Health. In addition, public infrastructure in some locations is deficient and living conditions are unfavorable, so that there is a need to invest in effective protection measures for vector control, as well as a focus on health education, whose HVL control measures in the municipality need to be readjusted. The high rate of cases and the constant presence of clusters in the municipality of Açu can be explained by the increasing degradation of the Caatinga biome, evidenced by the removal of firewood for use in the ceramist pole, whose activity is concentrated on a large scale in the use of raw material and energy, through the production of charcoal, for agricultural and livestock fronts, putting species of fauna and flora at risk. It is also noteworthy that this fact contributes to the destruction of wild ecotopes, resulting in the search for the vector for other sources of human and animal food, allowing an increase in the number of cases of the disease. It's concluded that canine visceral leishmaniasis is distributed in a large part of the state of Rio Grande do Norte. The underreporting and/or deficiency in the disclosure of data by some municipalities represents a challenge in complying with the actions of the Visceral Leishmaniasis Surveillance and Control Program, and attention should be paid to the monitoring and inspection of the execution actions of municipal managers, as well as how to train professionals who are part of the service.

First record of antibodies to the bluetongue virus in ewe (Ovis aries) in the state of Amazonas, Brazil / Primeiro registro de anticorpos para o vírus da língua azul em ovino (Ovis aries) no estado do Amazonas, Brasil

The objective of this work was to describe the first record of antibodies to the Bluetongue Virus (BTV) in ewe, in the state of Amazonas. The ewe, which was in twin pregnancy, gave birth on May 9, 2015, but a lamb died hours after delivery. Veterinary service was then requested by the owner, where emaciation, loss of wool, pyrexia, apathy, dyspnea, mucoid nasal secretion, facial, lingual and submandibular edema were observed. There was a visit by the Agricultural Defense Agency of the State of Amazonas to the property and blood samples were collected from the animal. The whole blood and serum were sent to the National Agricultural Laboratory, where it was possible to detect the presence of specific antibodies to BTV, through the Agar Gel Double Immunodiffusion. The ewe was submitted to a new blood collection, following the same protocols and the samples were sent to the Biological Institute of São Paulo, confirmed diagnosis. The animal in a serious clinical condition, could not resist and died in July 2015. The occurrence of an allochthonous case, in an area where vector insects occur, can trigger an endemic process in the Amazon region. With this, the epidemiological control of these occurrences is necessary, in order to avoid the spread of the disease in the country.

O objetivo do trabalho foi descrever o primeiro registro de anticorpos para o Vírus da Língua Azul (VLA) em ovino, no estado do Amazonas. A ovelha, que se encontrava em gestação gemelar, pariu no dia 9 de maio de 2015, porém um cordeiro faleceu horas após o parto. Foi então solicitado serviço veterinário por parte do proprietário, onde foi observado emaciação, perda de lã, pirexia, apatia, dispneia, secreção nasal mucoide, edema facial, lingual e submandibular. Houve visita da Agência de Defesa Agropecuária do Estado do Amazonas na propriedade e coletadas amostras de sangue do animal. O sangue total e soro foram enviados ao Laboratório Nacional Agropecuário, no qual foi possível detectar a presença de anticorpos específicos para VLA, através do teste de Imunodifusão Dupla em Gel de Ágar. A ovelha foi submetida a uma nova coleta de sangue, seguindo os mesmos protocolos e as amostras foram enviadas ao Instituto Biológico de São Paulo, confirmando diagnóstico. O animal em estado clínico grave, não resistiu e veio a óbito em julho de 2015. A ocorrência de um caso alóctone, em uma área de ocorrência de insetos vetores, pode desencadear um processo de endemia na região amazônica. Com isso, o controle epidemiológico destas ocorrências, se fazem necessários, afim de se evitar a disseminação da doença no país.

Agentes tóxicos em ruminantes diagnosticados no Serviço de Anatomia Patológica da UFRRJ, Rio de Janeiro - Brasil / Toxic agents in ruminants diagnosed in the Pathological Anatomy Service of the UFRRJ, Rio de Janeiro - Brazil

Background: Toxic agents are chemical substances or physical agents that, when interacting with living organisms, cause harmful effects. For animals, toxic products include those intended to combat endo and ectoparasites, rodenticide products, and heavy metals. Minerals and dietary additives, even if essential to the animal, can become toxic agents, among which sodium chloride, copper, urea, and ionophore antibiotics stand out. This study aimed to survey the diagnoses of accidental poisoning in ruminants over 65 years as recorded in the files of the Pathological Anatomy Sector of the Federal Rural University of Rio de Janeiro. Materials, Methods & Results: The diagnoses of poisoning by ticks, rodenticides, heavy metals, macro and micronutrients, and dietary additives in ruminants were made based on the association of epidemiological, clinical, and anatomopathological findings and, in some cases, by histochemical (rubeanic acid and Masson trichrome) and toxicological examinations. A review of data recorded over 65 years identified 372 poisonings in ruminants. Of these, 85.5% (318/372) were in bovine species and 14.5% (54/372) in goats, sheep, and buffaloes. The outbreak of poisoning by organophosphates resulted in the death of 16 cattle that ingested contaminated broken rice and corn. The spraying of this product on the bags was intended to control insects. Intoxication due to excessive administration of abamectin resulted in the intoxication of 16 calves, in two distinct farms. Toxicosis caused by coumarin derivatives resulted in the death of six cattle after accidental ingestion of these rodenticides near the pens. Arsenic poisoning occurred due to ingestion of ant poison, available in bone meal and a mineral salt, through baths with arsenic-based ticks, or in cases later confirmed by toxicological analysis, resulting in the death of 109 cattle. Sodium chloride toxicosis resulted in the death of 10 sheep...

Babesiose: um ponto de vista diagnóstico: relato de caso / Babesiosis: a diagnostic point of view - case report

A babesiose canina é uma doença transmitida pela picada de carrapatos, como o Rhipicephalus sanguineus, vetor de Babesia vogeli, um hemoprotozoário de extrema importância na Medicina Veterinária. Esse protozoário parasita os eritrócitos, levando a uma hemólise. O animal infectado pode apresentar febre, letargia, anorexia, anemia, mucosas pálidas ou ictéricas, hematúria e hepatoesplenomegalia. O diagnóstico presuntivo da babesiose canina pode se basear em histórico, anamnese ou exame físico, porém a confirmação é obtida por meio do exame parasitológico. Durante o atendimento, um cão, macho, cinco anos, boxer, apresentou apatia, hiporexia, hematúria, hipertermia. Para confirmação de diagnóstico foram solicitados os exames complementares: hemograma, alanina aminotransferase e creatinina. A única alteração encontrada foi diminuição de plaquetas, porém no esfregaço sanguíneo foram observadas estruturas de Babesia sp. livres e parasitando hemácias.(AU)

Canine babesiosis is a disease transmitted through tick bites, such as Rhipicephalus sanguineus, vector of Babesia vogeli, a hemoprotozoan of extreme importance in Veterinary Medicine. This protozoan parasites erythrocytes leading to hemolysis. The infected animal may have fever, lethargy, anorexia, anemia, pale or jaundiced mucous membranes, hematuria and hepatosplenomegaly. The presumptive diagnosis of babesiosis can be based on history, anamnesis or physical examination, but the confirmation is obtained through parasitological examination. During the service, a male dog, five years old, boxer, presented apathy, hyporexia, hematuria, hyperthermia. To confirm the diagnosis, a complete blood count, alanine aminotransferase and creatinine were requested. The only alteration found was a decrease in platelets, however, in the blood smear, Babesia sp. were detected free and parasitizing red blood cells.(AU)
