Estudo retrospectivo de osteossarcoma primário dos ossos da pelve em cães em um período de 14 meses

The osteosarcoma (OSA) is one of the most common malignant tumors of dogs. Large and giant-breed dogs are affected and the mean age of these dogs is about 7 years. The tumor usually involves the metaphyses of long bones and the treatment is radical amputation and chemotherapy with cisplatin. The therapy of neoplasia located in pelvis is difficult and usually don't accept by owners. This report describes the incidence of primary osteosarcoma in pelvis of dogs, during a period of fourteen months. Of the eight animals taken care with this neoplasia, a bigger frequency in the dogs of the race Rottweiler and German Pastor was observed. Amongst the bones that compose animal's pelvis was observed greater osteosarcoma incidence in ileum (6 cases). Lameness, functional impotence of pelvic member and pain had been the main observed clinical signals. In seven cases was found advanced involvement osseous, mainly, for lyses of the cortical. All the animals had been submitted to the euthanasia for not presenting possibility of surgical treatment with safety margin. Also one was taken in consideration for this decision to the clinical condition of the patients, the possibilities to confer improvement in the quality of life of the dogs and the option of the owners' front to the prognostic.

Tomografia computadorizada de abdome normal: Estudo retrospectivo das angulações dos hilos renais

OBJECTIVE: To obtain mean angulation values for renal hila in relation to the horizontal plane traced over the right and left spinal erector muscles, considering the center of the lumbar vertebral spine as a parameter for measuring the renal hila angles. MATERIALS AND METHODS: The authors have analyzed 250 abdominal computed tomography studies of both male and female healthy individuals (128 men with mean age 52.45 ± 17.42 years, and 122 women with mean age 54.39 ± 18.27 years), corresponding to 500 renal hila evaluated. The mean angulation of each hilum in relation to the horizontal plane was obtained taking acute angles into consideration. RESULTS: The comparative study have not found any statistically significant difference in acute angles of renal hila between male and female individuals. The statistical analysis demonstrated limits of 40.40° and 44.54° for mean right hilum angulation and 39.91° and 43.23° for mean left hilum angulation, with a confidence interval of 95% CONCLUSION: Renal hila present similar angulation independently of sex. Higher angulation values correspond to hyper-rotation or excessive rotation, and lower angulation values, to incomplete or reverse rotation. © Colégio Brasileiro de Radiologia e Diagnóstico por Imagem.

Estudo retrospectivo dos procedimentos anestésicos realizados em cães e gatos submetidos a neurocirurgias

Neurosurgeries are frequent in the routine of veterinary hospitals and, therefore, knowledge of the different anesthetic protocols to be used for each patient is necessary to prevent the morbity and mortality in the after and trans-surgical period. The objectives of this study were to evaluate the anesthetic protocols used in patients undergoing neurosurgeries; the results of those protocols; the rate of complications, and if those complications are related to the duration of the anesthesia time. We studied the anesthetical data of 52 dogs and two cats submitted to neurosurgery between January of 2003 and December of 2006, in the Veterinary Hospital of UEL. Findings showed that the main protocols used were propofol for induction and halothane or isofluorane for maintenance of the anesthesia. These protocols induced adequate anesthesia for the surgical procedure and did not occur complications during the anesthetic period in 37/54 (68,5%) of the cases. 7/19 (36.8%) of the complications observed occurred in patients submitted to anesthesia with halothane and 8/32 (25.2%) in patients with isofluorane. The complication most observed in this study was bradicardy, which occurred in 15/54 (27.8%) of the patients. Two deaths occurred in patients submitted to slot cervical. Good knowledge of the neurological disease and of surgical and anesthetic techniques are essential to prevent alterations in the central nervous system caused by the drugs, disease or association of these factors.
