Obesidade em pacientes candidatos a cirurgia bariátrica

Objective: To identify the demographic and clinical profile of individuals with severe obesity who were candidates for bariatric surgery. Methods: This was a descriptive study. Data were extracted from 252 medical records of candidates for bariatric surgery in the Hospital of the Federal University of Mato Grosso do Sul from 2004 through 2007. Results: The prevalence of obesity was associated with other chronic diseases related to the eating habits. The majority of candidates for bariatric surgery were whites (86.53%) and female (80.15%). The mean age of the candidates was 36.07±10.16 years. The most common commorbidities included high blood pressure (63.49%), dyspnea (55.56%), varicose veins (45.63%), and depression (36.51%). Conclusion: The major comorbidity associated with obesity is high blood pressure; individuals need be followed by a multidisciplinary team of health care providers.OBJECTIVE: To identify the demographic and clinical profile of individuals with severe obesity who were candidates for bariatric surgery.

EFEITO DO DICLOFENACO DE SÓDIO NA CICATRIZAÇÃO DA PAREDE ABDOMINAL DE RATOS

The aim of the experiment was to do a valuation of the effect of the sodium diclofenac on the collagenous sinthesis in abdominal wall healing. It was used 40 male Wistar rats to do longitudinal laparotomies with a standardized technique, divided into 2 groups: One without the drug (control group) and another group wich were administrated sodium diclofenac (3mg/kg) every day for 4 days. In the 7th and 14th postoperative day, 10 animals of each group were submitted to euthanasia and the front abdominal wall involving the scar was removed to be prepared to hystological analysis. The segments were prepared with Hematoxilyn-Eosin and Picrosirius Red F3BA, in order to do either a general view of healing process or a quantitative valuation of collagenous. The resultant data were submitted to statistical analysis. It was conclued that the abdominal wall scar in rats treated with sodium diclofenac had less collagenous fibres in the 7th and 14th postoperative days than rats from the control group.

Estudo comparativo entre a sutura contínua e a com pontos separados na parede abdominal de ratos

The purpose of the experiment was to compare the continuous and interrupted techniques of abdominal clousure. It was used 48 male rats Wistar to realize longudinal laparotomies with a standardized technique. In 24 of them, the abdominal wall was closed by continuous suture and in 24 of them closed by interrupted suture. All of them using polidioxanone. In the 7th and 14th postoperative day, 12 animals of each group were submitted to euthanasia and the front abdominal wall was removed (without skin) and divided in two segmentes (cranial and caudal), one for hystological analysis with an objective measurament og collagenous and another to the test of tensile strength by tensiometer. The resultant data were submitted to statistical analysis. It was conclued that in the 7th day , the abdominal wall closed by interrupted technique is more resistant without significant diferences on collagenous density than the other closed by interrupted, and at the 14th day the results are similar, in rats.

Síntese da parede abdominal: sutura contínua ou com pontos separados? Revisão da literatura

Nowadays , is belivied that the single-layer mass closure is better than the individual layer sutures, with less risk of complications. Although there is alot of materials to be used, the types preferable to be best used are the monofilament inabsorbable and the monofilament long-term absorbable suture. There still are doubts about abdominal closure using continuous or interrupted sutures. Different publications, with different methods and ways of valuation, conclude advantages for one or other technique, or conclude similar results. About these doubts, the authors relate the continuous and interrupted sutures on the abdominal wall closure, emphasizing the technical aspects.

The effect of platelet-rich plasma on the repair of muscle injuries in rats ☆

Objective The need for therapeutic options for muscle injuries, which are increasingly frequent among sports practitioners, was the motivation for this experimental study, which had the aim of evaluating the histological effects of platelet-rich plasma (PRP) on repairs to muscle tissues of rats. Methods PRP was obtained by means of double centrifugation of blood from five animals. In 30 rats, an injury was produced in the middle third of the belly of the gastrocnemius muscle of each hind limb. These injuries did not receive any treatment in six rats (12 legs). In 24 rats, 0.9% physiological serum was injected into the injury in the left leg and PRP into the injury in the right leg. Samples from the treated and untreated tissue were evaluated histologically 7 and 21 days after the procedures. Results The quantity of collagen in the injuries treated with PRP was significantly lower than that in the other injuries, in the evaluation made 7 days after the procedure, but it became equal to the other groups in the evaluation done on the 21st day. There was a significant increase (p < 0.001) in the quantity of collagen from the 7th to the 21st day in the injuries treated with PRP, but this was not seen in the injuries treated using other methods. The inflammatory process was shown to be more intense in the injuries treated with PRP than in the injuries of the other treatment groups, in the evaluation done 7 days after the procedure. However, the morphological aspects of these injuries were seen to be similar to those of the untreated injuries, 21 days after the procedure. Conclusion PRP promoted complete tissue restitution between the 7th and 21st days in experimental muscle injuries.

Perda insuficiente de peso e ou ausência de remissão da diabete melito tipo 2 após a derivação gástrica em Y-de-Roux: fatores que podem influenciar os resultados insatisfatórios

BACKGROUND Roux-en-Y gastric by-pass is considered one of the most effective treatments for maintaining long-term weight loss. However, it is associated to failures manifested by the inability to maintain weight loss, weight gain or poor glycemic control. OBJECTIVE Study the possible factors that influence weight loss failure and/or DM2 remission. METHODS Case-control study of 159 patients submitted to gastric by-pass two or more years postoperatively. Twenty-four individuals with unsatisfactory weight loss and/or DM2 remission were selected as cases and 24 with satisfactory weight loss and/or absence of DM2 remission as controls, matched for age and postoperative time. RESULTS Of the 24 cases and controls evaluated, the percentage weight gain was 19.32% and 8.68%, percentage DM2 remission 26.6% and 87.5% and percentage DM2 recurrence 6.6% and 0.0%, respectively. Cases and controls exhibited mean maximum preoperative BMI of 53.50±12.24 kg/m2 and 48.77±5.19 kg/m2, respectively. These values were statistically significant in terms of poor weight management or failed surgery. CONCLUSION Patients with elevated initial maximum BMI (≥ 50kg/m2) displayed higher weight loss failure rates. Food intolerance and socioeconomic differences are considered factors in weight gain.
