No. of bitstreams: 0 Previous issue date: 2005Uma mulher de 26 anos desenvolveu uma fístula arteriovenosa associada a pseudoaneurisma da artéria temporal superficial após traumatismo craniano fechado. Tais fístulas são raras e geralmente associadas a pseudoaneurismas da artéria temporal superficial, mais comumente do ramo frontal. As lesões habitualmente surgem tardiamente em relação ao traumatismo causador e se manifestam como uma massa dolorosa pulsátil na região temporal, crescente, associada à frêmito e sopro. O diagnóstico é confirmado através de arteriografia e o tratamento cirúrgico proporciona ótimos resultados.A 26 year-old woman suffered a blunt head injury on the left temporal area and developed an arteriovenous fistula with a pseudoaneurysm on the superficial temporal artery. These fistulas are rare and usually associated with pseudoaneurysms, most commonly in the frontal arterial branch. The aneurysms generally appear late after trauma and present as a pulsatile painfully growing mass in the temporal region, associated with fremitus and bruit. The diagnosis is made by angiography and surgery is a very effective treatment.[Leal, Francisco Sérgio Cavalcante Barros; Miranda, Carla Ceres Villas; Guimarães, Antônio Celso Alvarenga] Universidade de Taubaté, Brazi

Use of Equine Pituitary Extract (EPE) in low doses to induce double ovulation in mares

The aim of this study was to evaluate the effect of treatment using low doses of EPE on rates of ovulation and embryo recovery. Eight mares were used in this way: first cycle (n = 8) - control group (untreated); second cycle (n = 8) - treated group using 8.0 mg of EPE, bid, until at least two follicles reached ≥35 mm diameter. At this moment, was administered 1000 IU hCG, E.V., as ovulation agent. The embryos recovery were performed eight days after detection of second ovulation. Mares received 5.0 mg PGF2α, I.M. on D8. The percentage of mares that showed two or more ovulations was higher (p 0.05) between the treated (11/16, 68.8%) and control (6/9, 66.6%)  groups. The results of this study allow concluding that treatment using low doses of EPE increased the incidence of multiple ovulations and provided greater recovery embryos rate
