Validation of a measure of perfectionism.

This article describes perfectionism, or the holding of and striving for unrealistically high standards, and presents two studies undertaken to investigate the convergent, discriminant, and predictive validity of the Perfectionism Scale (PS; Burns, 1980). College students in the first study completed the PS, several other measures of high standards, and measures of constructs that, conceptually, are differentially related to perfectionism. Correlational analyses indicated that the Perfectionism Scale has convergent and discriminant validity and seems to measure self-oriented perfectionism. The second study attempted to determine the predictive validity of the PS by testing a vulnerability model of subclinical depression outlined in Hewitt and Dyck (1986). PS scores were used to predict depressed mood changes in female college students following failure on important and unimportant tasks. As expected, the results indicated that perfectionism interacted with failure on important versus unimportant tasks to produce dysphoric mood. Evidence for the predictive validity of the PS was thus shown. Several directions for future research are discussed.

[Treatment of cicatricial stenosis of the proximal common hepatic duct. Study of 11 cases].

Eleven patients with cicatricial stenosis in the junction area of hepatic ducts were evaluated. In all patients the injury occurred during cholescystectomy and no operative cholangiography was performed. In 3 patients the injury was recognized during the initial cholecistectomy. Ten patients had been operated on at least one time to correct the injury in other Services. Four cases had duct or peritoneal drainage. There was an attempt of reanastomosis in two cases. Five patients had a bilio-digestive anastomosis performed in variable occasions. Two patients were reoperated 5 times, one patient 3 times. The others were submitted to one or 2 reoperations. There were a period of 1 to 72 months between the injury and last reoperation. Jaundice was the most common presenting manifestation since it appeared in all patient except one. Five patients had biliary cirrhosis. Roux-en-Y hepaticojejunostomy was carried out in all cases after enlarging the biliar stoma by longitudinal section on the left hepatic duct and performing a termino-terminal anastomosis. The 10 or 12 caliber Kehr drain used was taken out after the control cholangiography, carried around the second postoperative week. Concerning the long term results, one patient died of recurrent cholangitis six months after the 6th reoperation and one patient 14 months after the 4th reoperation of liver failure. Both had biliary cirrhosis. Two patients, remained assymptomatic for 60 months and 3 patients for 24, 37 and 56 months. The importance of preventing this severe complication is stressed by the authors. Patients with such lesions need be referred to specialized centers where well trained surgeons are available. The technique herein presented seems us to be a good option.

[Results of spleno-renal anastomosis in the treatment of portal hypertension due to mansoni schistosomiasis. Apropos of a review of the literature].

1001 cases of spleno-renal shunts taken from 26 publications were selected after a literature review. The great majority of these were retrospective and had a very poor follow-up. The operative mortality levels were acceptable (4,5%) and the portal pressure decreased considerably. Nevertheless it has been shown that in 30,3% of the cases, thrombosis of the anastomosis developed. Recurrence of bleeding occurred in 16% of a population in which permeability of the anastomosis had not been controlled and it could be estimated that it goes up to 52% for the group with thrombosis of their anastomosis. Portal systemic encephalopathy varies with age, being 17% for people below 38,5% above 44 years of age.
