RESSECÇÃO CIRÚRGICA DE HIPERPLASIA DE PALATO DURO EM EQUINO

Descreve-se um caso de hiperplasia de palato duro em um equino de 15 anos de idade atendido no Hospital de Clínica Veterinária CAV/UDESC em Lages, SC. O animal apresentava distúrbios durante a alimentação, como a dificuldade em apreender o alimento, queda deste durante a mastigação e emagrecimento progressivo, há aproximadamente cinco meses. Na inspeção da cavidade oral constatou-se aumento de volume da parte mais rostral do palato duro ultrapassando a borda oclusão dos dentes incisivos. Nenhuma outra alteração na cavidade oral que justificasse o problema foi identificada no exame físico. Como tratamento realizou-se a ressecção cirúrgica do tecido hiperplásico e a hemostasia realizada com ferro candente, em estação, sob sedação e anestesia local. Após o procedimento observou-se melhora significativa da capacidade apreensiva e mastigatória do alimento. Aos sete dias pós-cirúrgico foi observada boa cicatrização da ferida e ausência da queixa inicial. O diagnóstico e a indicação cirúrgica como tratamento nos casos de hiperplasia do palato duro é ainda conflitante e pouco discutida na literatura, necessitando cautela e perícia para o diagnóstico. No caso descrito obteve-se sucesso com a remoção cirúrgica, podendo ser indicada em casos de hiperplasia de palato duro, quando associado a sinais clínicos

PRESENCE OF Salmonella sp. IN SWINE CARCASSES SAMPLED AT DIFFERENT POINTS OF THE PROCESSING LINE PRESENÇA DE Salmonella sp. EM CARCAÇAS SUÍNAS AMOSTRADAS EM DIFERENTES PONTOS DA LINHA DE PROCESSAMENTO

Salmonella sp. is responsible for infections in pigs and in human being important for public health and meat production. With the aim of detecting the presence of Salmonella sp. on pig carcasses throughout the slaughter line, as well as to identify the serovars and serology results, three visits to a slaughterhouse in the state of Santa Catarina were done. In each visit, 15 blood samples were collected and, at the slaughter line, six carcasses were sampled. From each carcass, four swabs were collected (after scalding, flaming, evisceration and washing) on a 300 cm2 (20 X 15) area from the fore-part. From the same carcasses fragments from the intestine were also collected. In each visit swabs from the saw, lairage floor, and water from scalding tank were collected. Salmonella sp. was isolated from seven carcass swabs (one after scalding and dehairing, four after evisceration and two after washing), as well as from one swab from the floor, one water sample, and six intestine content samples. Serovars  Typhimurium (7/15 or 46.7%) and Derby (4/15 or 26.7%) were the most frequent. The serology identified 71.1% positive animals. <br /><br />KEY WORDS: Carcasses, slaughter line, swines, Salmonella.<br /> <p class="MsoNormal" style="margin: 0cm 0cm 0pt; line-height: 150%; text-align: justify">Salmonella é responsável pelo aparecimento de infecções em suínos e em seres humanos, influenciando na produção de carnes e na saúde pública. Com objetivo de verificar a presença de Salmonella sp. em carcaças suínas na linha de abate, bem como os sorovares presentes e associar com a pesquisa de anticorpos, realizaram-se três visitas a um abatedouro no Estado de Santa Catarina. Em cada visita foram coletadas quize amostras de sangue no momento da sangria e na linha de abate, material de seis carcaças. Para cada carcaça realizaram-se quatro amostragens com suabes, em uma área de 300cm² (20x15) da região anterior, após escaldagem, flambagem, evisceração e lavagem. Dessas carcaças, também, foram coletados fragmentos de intestino. Em cada visita coletaram-se suabes da serra de corte, do piso da baia de espera e água do tanque de escaldagem. Isolou-se Salmonella sp. em sete suabes de carcaças (um após a escaldagem e depilação, quatro após a evisceração, dois após lavagem da carcaça), em um suabe de piso, uma amostra de água e em seis amostras de conteúdo intestinal, destacando-se como mais frequentes os sorovares Typhimurium 7/15 (46,7%) e Derby 4/15 (26,7%).

Programa de Pós-Graduação em Ciência Animal, Centro de Ciências Agroveterinárias, Universidade do Estado de Santa Catarina, Avenida Luís de Camões, 2090, Bairro Conta Dinheiro, Lages, SC 88520-000, Brasil. E-mail: [email protected] The clinical endotoxemia is difficult to diagnosis and treatment because of the involvement of multiple organs. This study aimed to evaluate the clinical effects of subanesthetic doses of ketamine, before or after the induction of endotoxemia in cats. Were used nine healthy cats, with 4.3±0.59 kg, autocontroles, placed into three groups: lipopolysaccharide (LPS, n=9) received a bolus of NaCl 0,9 % followed by a continuous infusion (CI) of LPS for two hours and; bolus of NaCl 0,9 % followed by CI of LPS for two hours; ketamine/LPS (C/ LPS, n=9) received a bolus of ketamine followed by ketamine CI and LPS for two hours and, after, bolus of saline followed by CI of LPS for another two hours; LPS/ketamine (LPS/C, n=9) received bolus of saline followed by a CI LPS for two hours and then after bolus of ketamine followed by the same CI associated with LPS for two hours. The heart rate was higher for 5 to 120 minutes after initiation of the CI LPS in C/LPS and less than 150 to 240 minutes and from 600 to 720 minutes in LPS compared to the other groups. Five minutes after CI LPS initiation in C/LPS, 60 minutes in LPS/C and 90 minutes to 720 minutes in LPS, FC was higher than at baseline. The PAS was lower in all groups from 360 to 720 minutes compared to baseline. All treatments showed increased TR from 60 to 600 minutes compared to baseline. The levels of glucose and lactate increase from 120 to 360 minutes compared to baseline in all groups. The leukocyte decreased from 60 to 360 minutes in all treatments compared to baseline. It is concluded that ketamine at subanesthetic doses, before or after induction of endotoxemia in cats has minimal cardiovascular effects, but does not inhibit or reverse hyperthermia and leukopenia produced by endotoxemia in cats

Electrocardiogram in Bitches Submitted to Unilateral Total Mastectomy

Background: The frequency of oncological diseases in companion animals has increased in recent years, mainly due to the longer longevity of dogs. The neoplasms are not only open by the presence of the tumor and its location, but also by paraneoplastic syndromes, which are disorders that occur due to the production of substances by the tumor that cause. In addition to causing local changes and damages, oncological diseases may also result in injuries at distant sites, such as paraneoplastic syndromes, which, if untreated, may result in death of animals. The present study aimed to investigate whether female dogs with mammary tumors demonstrate electrocardiographic changes, and if so, to investigate whether these cease after removal of the tumor, and to relate the type of tumor with the occurrence of arrhythmias. Materials, Methods & Results: Eighteen female dogs, aged between 4 and 14 years, underwent electrocardiogram 24 h prior to undergoing a total unilateral mastectomy. After removal of the tumor, electrocardiograms were again performed 24 (M24), 48 (M48), and 72 (M72), as well as 14 days (M14d) after surgery. Histological analysis of the neoplasms showed that 55% of the tumors were benign, with predominance of adenoma (38%), and 45% were malignant, with predominance of adenocarcinoma (22%). The following rhythms and arrhythmias were observed: normal sinus rhythm (37.2%), sinus arrhythmia (62.8%), wandering pacemaker (26%), 1st degree atrioventricular block (AVB; 5%), premature ventricular complex (PVC; 10%), and T-wave > 25% of R-wave (25%); more than one change could occur simultaneously. Out of the evaluated electrocardiographic parameters, a significant difference was observed in the QT interval between the following timepoints: M24 (204 ± 18), M48 (204 ± 22), and M72 (203 ± 23), as well as Mbasal (192 ± 15) and M14d (178 ± 43).Discussion: Regarding the observed rhythms, arrhythmias, and changes, respiratory sinus arrhythmia was the normal predominant rhythm, followed by sinus rhythm. Wandering pacemaker in conjunction with respiratory sinus arrhythmia is widely observed in dogs; these conditions occur due to vagal predominance, without hemodynamic consequences. PVC is the premature depolarization originating in ectopic foci of the ventricular tissue, and is considered the most common type of ventricular arrhythmia in small animals. Two animals demonstrated PVC, one in Mbasal and the other in M14d. The former presented with a tumor diagnosed as an adenocarcinoma, which could be related to the paraneoplastic syndrome. The later presented with a tumor diagnosed as an adenoma, indicating that PVC may have occurred due to stress at that time. The T-wave occurs after ventricular depolarization, and is usually up to 25% of the amplitude of the R-wave. This change was observed at all times for the animal that was histologically diagnosed as having mammary adenocarcinoma, and may have been related to the neoplasm or be an individual change. The 1st degree AVB occurred in Mbasal, and was therefore related to increased vagal tonus. The significant differences in the QT interval were negatively correlated with decreased heart rate (HR), i.e., the QT interval increased when HR decreased. This must have been related to the acclimatization of the animals to the tests. Owing to the high number of animals with early-stage mammary tumors in this study, the observed electrocardiographic changes could not be correlated with tumor presence and type
