Therapeutic option for children with esophageal caustic stenosis

Caustic ingestion is a leading cause of esophageal stenosis in children. Herein we report four cases using mitomycin C (MMC), a drug that inhibits cell division, protein synthesis and fibroblast proliferation and has been used as an adjuvant therapy for caustic esophageal stenosis that is recalcitrant to conventional dilation techniques. A retrospective chart review was performed on four pediatric patients with severe, recurrent esophageal stricture after caustic ingestion. The patients had required six to 20 esophageal dilations over a 4-16-month period before MMC application. MMC was applied after an endoscopic dilation on saturated pledgets at a dose of 0.1 mg/mL for 2 min in the area where the strictures had been lyzed. From the four children treated with MMC, two have been asymptomatic for 16 and 20 months and two still require esophageal dilation, however, at longer intervals. All patients have shown satisfactory weight gain with food intake exclusively per oral. Although further studies are required, there is strong evidence that MMC is a safe and effective adjuvant therapy in the treatment of esophageal caustic stenosis. © 2008 The Authors.

Evaluation of creatine kinase (CK) and aspartate aminotransferase (AST) activities after laparoscopic or conventional ovariectomy in queens

Creatine kinase (CK) and aspartate aminotransferase (AST) are mainly muscle-specific enzymes, which can be associated with muscle tissue damage. The aim of this study was to assess the activities of CK and AST during the postoperative period, after conventional (G1) and videolaparoscopic ovariectomy (G2), in queens. A further group (G3) was subjected to anaesthesia only. Results demonstrate that there were significant differences between groups. The highest levels of CK were recorded in Gl, however at a confidence level of p < 0.05 there was no significant difference between groups during the first 6 hours after surgery. A significant (p < 0.05) increase of CK values was identified between 0h and 3h in both groups (Gl and G2). Regarding AST activity there was no significant variation between groups, but again there was a significant difference between values at 0h and 3h after surgery. In conclusion, ovariectomy performed by videolap-aroscopy seems to cause less muscle damage when compared to the conventional method. © 2009 by Verlag Hans Huber, Hogrefe AG, Bem.

Partial external mitral annuloplasty in dogs with myxomatous mitral valve degeneration and congestive heart failure: Outcome in 9 cases

Objective: To report the outcome of partial external mitral annuloplasty in dogs with congestive heart failure (CHF) due to mitral regurgitation caused by myxomatous mitral valve degeneration (MMVD). Animals, materials and methods: Nine client-owned dogs with CHF due to mitral regurgitation caused by MMVD. Surgery consisted of a double row of pledget-butressed continuous suture lines placed into the left ventricle parallel and just ventral to the atrioventricular groove between the subsinuosal branch of the left circumflex coronary artery and the paraconal branch of the left coronary artery. Results: Two dogs died during surgery because of severe hemorrhage. Two dogs died 12 and 36 h after surgery because of acute myocardial infarction. Three dogs were euthanized 2 and 4 weeks after surgery because of progression of CHF, 1 was euthanized 30 days after surgery for non-cardiac disease, and 1 survived for 48 months. In the 5 dogs that survived to discharge there was no significant change in the left atrium to aortic ratio with surgery (3.6 ± 0.56 before surgery; 3.1 ± 0.4 after surgery; p = 0.182), and no significant change in mitral regurgitant fraction in 4 dogs in which this measurement was made (78.7 ± 2.0% before surgery; 68.7 ± 7.5% after surgery; p = 0.09). Conclusions: Partial external mitral annuloplasty in dogs with CHF due to MMVD was associated with high perioperative mortality and most dogs that survived to discharge failed to show clinically relevant palliation from this procedure. Consequently, partial external mitral annuloplasty is not a viable option for dogs with mitral regurgitation due to MMVD that has progressed to the stage of CHF. © 2011 Elsevier B.V.

Acurácia da histerossonografia versus ultrassonografia transvaginal em mulheres inférteis candidatas às técnicas de reprodução assistida

PURPOSE: To compare the diagnostic accuracy of sonohysterography (HSN) and conventional transvaginal ultrasound (USG) in assessing the uterine cavity of infertile women candidate to assisted reproduction techniques (ART). METHODS: Comparative cross-sectional study with 120 infertile women candidate to ART, assisted at Centro de Reprodução Assistida (CRA) of Hospital Regional da Asa Sul (HRAS), Brasília-DF, from August 2009 to November 2010. Sonohysterography was performed with saline solution infusion in a close system. The sonohysterography finding was compared to previous USG results. The uterine cavity was considered abnormal whenthe endometrium was found to be thicker than expectedduring the menstrual cycle and whenan endometrial polyp, a submucous myoma and an abnormal shape of the uterine cavity were observed. The statistical analysis was doneusing absolute frequencies, percentage values and the χ 2, with the level of significance set at5%. RESULTS:HSN revealed that 92 (76.7%) infertile women candidate to ARThad anormal uterine cavity, while 28 (23.3%) had the following abnormalities: 15 polyps (12.5%).
