Um caso raro de destruição total do pâncreas por pancreatite em cão

ABSTRACT A 16-year-old female Poodle entered UFMG’s Veterinary Hospital with severe prostration, lack of appetite, and vomit. During physical examination, abdominal pain, dehydration, and hyperglycemia (448mg/dl) were found, therefore the animal was admitted under the suspicion of diabetic ketoacidosis. Screening revealed metabolic acidosis, hyperkalemia, glycosuria, ketonuria, and proteinuria. Leukocytosis, thrombocytosis, increase in the number of hepatic enzymes and hyperglycemia were also present in these tests. The ultrasound images showed a smaller and hypoechogenic pancreas, irregularity and folds in duodenum and reactivity of the surrounding tissue, indicating pancreatitis. Thirty days after the dog had been discharged for treatment at home, it was taken back to the veterinary hospital due to status epilepticus, which motivated the owner’s decision of euthanasia. During post mortem examination no trace of pancreas was found. On histological examination of the adipose tissue next to the duodenum, only one pancreatic duct was seen, together with inflamatory cells , thus characterizing a rare case of total pancreatic destruction due to pancreatitis

Diffuse heterotopic hair in a canine uterus: case report

The present report describes the clinical and pathological findings related to diffuse heterotopic hairs associated with pseudo-placentational endometrial hyperplasia in a canine uterus. Macroscopically, the uterus was intensely enlarged and thicker, and the endometrial surface was irregular and covered with black hairs similar to the hairs of the bitch. Histologically, heterotopic hairs associated with pseudo-placentational endometrial hyperplasia were observed

Esterilização em gatas mediante salpingectomia parcial (incluindo prenhes) versus ovariossalpingohisterectomia Sterilization in queens by partial salpingectomy (including pregnant) versus ovariohysterectomy

A ligadura ou laqueadura das tubas uterinas é uma forma de contracepção bastante utilizada na medicina humana. Ela consiste na oclusão mecânica e/ou ressecção parcial desta estrutura (salpingectomia parcial). Nesta pesquisa, procurou-se utilizar uma técnica de contracepção definitiva em gatas prenhes, que não comprometesse a gestação em curso, o parto, nem os conceptos, tendo em vista a frequência da visualização de útero gravídico nas campanhas de castração. Avaliou-se também o ganho de peso e mudanças de comportamento das gatas submetidas à salpingectomia parcial, comparando-as com as submetidas à ovariossalpingohisterectomia (OSH), além de comparar o tempo cirúrgico entre os dois procedimentos. Para tal, foram utilizadas 40 gatas, distribuídas em dois grupos de 20 animais, GA: salpingectomia parcial, e GB: OSH; sendo o primeiro subdividido em GA1 contendo 10 gatas prenhes e GA2 contendo 10 não prenhes. Todos os animais foram reavaliados com sete, 60, 180 e 365 dias. O tempo cirúrgico apresentou diferença estatisticamente significativa entre os grupos, sendo o GB mais demorado. Nas gatas do grupo GA1, o curso gestacional e o parto foram normais. No total, foram visualizadas 51 vesículas embrionárias, nasceram 49 fetos vivos e ocorreram duas reabsorções fetais. Dentre os 49 fetos, sete (14,28%) apresentaram a anormalidade genu recurvatum. Quanto à fertilidade, os animais do grupo A que ciclaram e copularam não engravidaram. Apenas o grupo B apresentou aumento de peso médio (20,34%) estatisticamente significativo. Com relação aos parâmetros comportamentais, o grupo B apresentou maiores alterações quanto ao aumento na ingestão de alimentos, aumento da letargia e diminuição do período de vigília. Concluiu-se que a técnica de salpingectomia parcial realizada em gatas é um método contraceptivo 100% eficaz, de rápida execução, que pode ser empregado durante a identificação transcirúrgica do estado de prenhez, com mínimo efeito prejudicial aos conceptos e sem alterações significativas de conduta e ganho de peso, mas com características indesejáveis quanto à aceitação dos proprietários.<br>The tubal occlusion is a form of contraception used in human medicine, which consists of mechanical occlusion and / or partial resection of this structure (partial salpingectomy). In this study, we tried to use a technique for definitive contraception in pregnant queens, that would not compromise the current pregnancy, the birth of kittens, and the concepts, considering the frequency of the visualization of gravid uterus in castration campaigns. Another objective was evaluate weight gain and changes in behavior of queens submitted to partial salpingectomy, comparing them with those submitted to ovariohysterectomy (OSH), and to compare the time between both surgical procedures. Were used 40 queens, divided into two groups of 20 animals, GA: Partial salpingectomy, and GB: OSH. The group GA, was divided in GA1, containing 10 queens pregnant and GA2 containing 10 non-pregnant. All animals were assessed with seven, 60, 180 and 365 days. The surgical times showed statistically significant difference between the groups, with GB slower. The gestacional course and birth of kittens were normal in queens of group GA1. A total of 51 embryonic vesicles were visualized, 49 born live fetuses, and occurring two fetals resorptions. Among the 49 fetuses, seven (14.28%) presented genu recurvatum. With respect to fertility, the animals in group A that cycled and mated, did not get pregnant. Only the Group B showed average weight increase (20.34%) statistically significant. Regarding the behavioral parameters, the group B showed increase in food intake, increase of the lethargy, and decreased in waking period. It is concluded that the technique of partial salpingectomy performed in queens is a 100% effective contraceptive method of rapid execution, which can be employed during the transoperative identification of pregnancy, with minimal adverse effects on fetuses, no significant changes of behavior neither weight gain, but with undesirable characteristics on the acceptance of owners
