1. Radiologista chefe no Hospital das Clínicas Samuel Libânio, Pouso Alegre (Minas Gerais), Brasil. 2. Residentes em radiologia no Hospital das Clínicas Samuel Libânio, Pouso Alegre (Minas Gerais), Brasil. Resumo: A patient with 80 years of age, admitted with continuous abdominal pain, especially in the lower left quadrant and Stopping gas and stool for six days. She presented sweating, tachycardia, normotensive, and innocent cardiopulmonary auscultation. Past Cholecystectomy and appendectomy. Unchanged laboratory tests. Radiography and computed tomography of the abdomen showed pneumoperitoneum In the right subphrenic region. Patient was submitted to exploratory laparotomy and no signs of hollow viscera perforation were found after search The etiology. This is indeed an idiopathic cause, having evolved well after the procedure. However, there is no consensus Relation to the best type of intervention.Pneumoperitoneum. Idiopathic. Elderly.: Paciente com 80 anos, admitido com quadro de dor abdominal, em pontada, contínua, especialmente em quadrante inferior esquerdo e parada de eliminação de gases e fezes há seis dias. Apresentava-se sudorético, taquicárdico, normotenso, ausculta cardiopulmonar inocente. Passado de em região subfrênica direita. Paciente foi submetido à laparotomia exploradora e não foram evidenciados sinais de perfuração de víscera oca pós-busca minuciosa da etiologia.: Trata-se realmente de causa idiopática, tendo evoluído bem após o procedimento. Entretanto, não há consenso em relação ao melhor tipo de intervenção.Pneumoperitônio. Idiopático. Idoso INTRODUÇÃOO pneumoperitônio frequentemente é causado por perfurações devido ao fato de ser um achado incomum no dia a dia da RELATO DE CASO

The aim of this study was to evaluate differences in behavioral responses of individually housed dairy-beef crossbred calves to standardized personality tests (novel person, novel object, and startle test) and investigate associations of personality traits with performance and home pen behavior. Dairy-beef crossbred (Holstein x Angus) calves (n=29) were individually housed with ad libitum access to water and calf starter. Body weight was measured weekly and calf starter intake was recorded daily from day of arrival (8.5 ± 2.1; experimental day 1) for 76 days. Behavior within the home pen (eating, drinking, non-nutritive oral manipulation) and activity were recorded on experimental days 13, 32, 53, and 67 using a camera and a pedometer. The calves were subjected to standardized personality tests in their home pen at the end of the experimental period (80.7 ± 2.0 d of age), including a novel person test (stationary person in the corner of their home pen) and combined novel object/startle test (remote-controlled car in the pen, that suddenly moved when touched). A principal component analysis on the behaviors recorded from the tests (latency to approach person or object, time spent attentive and touching the person or object, and time spent inactive, playing and grooming) yielded 3 factors that explained 76.1% of the variance, and were interpreted as personality traits labeled “fearful”, “inactive”, and “bold”. These factors were examined in regression analyses for their associations with home pen behavior and performance. The factor “fearful” had negative associations with total average daily gain and average grain intake. In contrast, the factor “inactive” had positive associations with non-nutritive oral manipulation of buckets or walls. The factor “bold” had no significant association with any of the performance or home pen behavior measures. In conclusion, personality traits identified from standardized tests were related to performance and home pen behavior measures in individually housed, crossbred calves. These results complement work in group housed calves suggesting personality testing may be useful selective tools to identify high and low performing calves from an early age.
