RESUMO

A mumificação fetal é um processo que ocorre após a morte do feto, que já tem mineralização da matriz óssea do esqueleto. O mecanismo exato deste fenômeno não é totalmente conhecido, entretanto, sabe-se que após a morte fetal ocorre rápida absorção dos fluidos uterinos e fetais juntamente com a involução uterina. As membranas fetais e placentárias desidratadas aderem ao feto formando uma massa seca e dura. Apesar de ser considerada incomum, já foi descrita em várias espécies de animais. É de rara ocorrência em cadelas e gatas. O objetivo deste artigo foi relatar o diagnóstico acidental de mumificação fetal em uma cadela com sinais de alteração cardíaca. Uma cadela de 11 anos apresentando sinais de insuficiência cardíaca congestiva foi submetida a radiografia torácica para avaliação da cardiopatia. No exame radiográfico foi observado acidentalmente a presença de um feto mumificado na cavidade abdominal cranial direita. A paciente foi submetida ao tratamento clínico para estabilização e controle dos sinais e apresentou, posteriormente, uma rápida recuperação clínica. O animal não apresentava sinais ou complicações decorrentes da mumificação fetal. Visto isso e para não a submeter aos riscos cirúrgicos, a tutora optou por não realizar o procedimento cirúrgico para retirada do feto. O presente relato descreve um caso clínico atípico de mumificação em cadela, pois não houve procedimento terapêutico específico e isso não interferiu com a boa qualidade de vida da paciente.

Fetal mummification occurs after the death of the fetus, which already has mineralization the skeleton bone matrix. The exact mechanism of this phenomenon is not fully understood; however, it is known that after fetal death a fast absorption of uterine and fetal fluids take place along with uterine involution. Dehydrated fetal and placental membranes adhere to the fetus forming a dry, hard mass. Although considered unusual, it has been described in various species of animals. It is rare in dogs and cats. The purpose of this paper was to report the accidental diagnosis of fetal mummification in a bitch with signs of cardiac alteration. An 11-year-old bitch showing signs of congestive heart failure was admitted to a veterinary clinic and it was requested to perform chest radiographs for heart evaluation. Radiography accidentally revealed the presence of mummified fetus in the right cranial abdominal cavity. The patient was submitted to clinical treatment for stabilization and control of the disease signs and clinical recovery rapidly occurred. The animal showed no signs or complications due to fetal mummification and had a good quality of life. Once the dog was clinically normal, and not to submit it to surgical risks, the owner chose not to perform the surgical procedure to remove the mummified fetus.

RESUMO

The aim of this study was to evaluate the effects of Psyllium (PSY) and Carboxymethylcellulose (CMC) administration on fecal elimination of sand in horses with asymptomatic sand accumulations. Eight horses were selected from sandy areas and randomly divided into 2 groups of four animals. The subjects were treated either with CMC or PSY. The presence of intestinal sand was confirmed through radiography and glove sedimentation test. The study was performed in two phases, with a 7-day interval. In phase I, all the animals received 8 liters of warm water; in phase II, the CMC group received 8 liters of water + 1g/kg of CMC, whereas the PSY group received 8 liters of water + 1g/kg of PSY. All administrations were performed through nasogastric intubation and fractionated in 2 equal volume administrations with an interval of two hours. General and specific physical examination of the digestive system were performed in conjunction with abdominal ultrasonography before the administrations and after 6, 12, 24, 36 and 48 hours, aiming to evaluate intestinal motility and presence of sand. All the feces eliminated by the animals within the 72 hours following the administrations were quantified, diluted and sedimented in order to calculate the sand output (g/kg of feces). All the animals were also subjected to radiographic examination to quantify sand accumulation prior to phase I and after 72 hours of phases I and II. No adverse effects were observed after the treatments. It was possible to notice higher sand elimination in both groups during the phase I, whereas no difference was observed in sand elimination rates between the groups in phase II. The radiographic scores presented differences between the initial timepoint and 72h in phases I and II for both groups. Based on the sand elimination rates and radiographic score, this study demonstrated that sand output was greater after administration of water alone, compared to CMC and Psyllium, leading to the inference that removal of the sandy environment and prevention of sand re-ingestion are effective measures for the elimination of sand from the colon of horses with asymptomatic sand accumulations.(AU)

O objetivo deste estudo foi avaliar os efeitos da administração do psyllium (PSY) e da carboximetilcelulose (CMC) sobre a eliminação fecal de areia em equinos com sablose assintomática. Oito equinos com confirmação radiográfica de sablose assintomática foram divididos em dois grupos (grupo CMC e grupo PSY). O estudo foi realizado em duas fases, com intervalo de sete dias. Na fase 1, todos os animais receberam 8L de água; na fase 2, o grupo CMC recebeu 8L de água + 1g/kg de CMC e o grupo PSY recebeu 8L de água + 1g/kg de PSY. Antes da administração de cada solução e após seis, 12, 24, 36 e 48 horas, foram realizados exame físico e ultrassonografia abdominal. Todas as fezes eliminadas em 72 horas foram avaliadas para quantificar a eliminação de areia (g/kg de fezes). Antes da fase 1 e após 72 horas das fases 1 e 2, o exame radiográfico foi realizado para quantificar o escore de acúmulo de areia. Houve maior eliminação de areia após a administração de água em comparação com a administração de CMC, e não se observou diferença entre a CMC e o PSY. Uma redução significativa nos escores radiográficos de acúmulo de areia foi observada após a administração de água, bem como a manutenção dos escores após a administração da CMC e do PSY. Com base na produção de areia e no escore radiográfico, este estudo sugere que a remoção do ambiente arenoso, impedindo a reingestão de areia, é uma medida eficaz para a eliminação da areia do cólon de cavalos com acúmulos de areia assintomáticos.(AU)

RESUMO

Background: Portosystemic deviation (PSD) is a congenital or acquired vascular anomaly that allows an abnormal bloodflow from the portal vein directly to the systemic circulation. This liver by-pass avoids hepatic metabolism of severaltoxins. Congenital PSDs are usually solitary and extra-hepatic, with a high incidence in pure-breed dogs. Acquired PSDsare usually multiple and occur as a consequence of portal hypertension. Surgery is the definitive treatment. Cliniciansand surgeons may present difficulties in the propaedeutic of animals with PSD. This paper aims at reporting a successfulsurgical treatment of a solitary extra-hepatic congenital PSD in a mixed-breed dog.Case: A 7-month-old mixed-breed dog, female, spayed, weighing 8 kg, was presented with a history of sudden syncopeafter feeding. Complementary exams revealed normocytic hypochromic anaemia, hypoalbuminemia and increased alanineaminotransferase and alkaline phosphatase. Abdominal ultrasound revealed an anomalous vessel inserted in the caudalcava vein, compatible with a congenital extra-hepatic PSD. Computed tomography revealed the anomalous vessel, with1,1 cm of diameter, originated from the cranial mesenteric vein and it inserted in the cranial margin of the caudal cavavein. A medical support was started with hydration, metronidazole, lactulose, probiotic and Hepatic diet. After 15 days thedog was submitted to surgery and a 5 mm ameroid constrictor ring was placed to gradually close the anomalous vessel.The dog recovered well and an abdominal ultrasound was repeated after 30 days, showing the ameroid constrictor ringring in the left cranial abdominal region, occluding the PSD close to its insertion in the caudal cava vein...(AU)

RESUMO

Fecaloma or fecolyte refers to the accumulation of feces that become dry, compacted and retained inside the large intestine where they dehydrate and solidify, leading to intestinal constipation. Its etiology is quite heterogeneous, ranging from infections and intestinal tumors, inadequate water consumption, dehydration, unbalanced diet or ingestion of foreign materials. For the treatment, it is possible to perform drug therapy in order to lubricate the intestinal contents and allow it to be moved to the final portion of the rectum and finally expelled from the organism or, depending on the case, surgical intervention is chosen. In this study, a case of fecaloma treated with enterotomy in Fortaleza will be reported.(AU)
