Colonic diverticular disease in patients 40 years old or younger.

Diverticular disease in patients 40 years of age or younger has been described as rare but virulent. Previous studies, based on age, on diverticular disease are often confusing because of inexact definitions of the disease status. With these criticisms in mind, the authors studied 322 clinical records on patients admitted with a diagnosis of colonic diverticulosis or diverticulitis to the University of New Mexico Hospital and the Lovelace Medical Center. Of these patients, 285 had documented evidence of colonic diverticula with only 6 per cent of these being 40 years of age or younger. The criteria for acute diverticulitis were met by 86 patients, 17 of whom were 40 years of age or younger. The younger group had disproportionately more men, particularly Hispanics. The authors conclude that acute diverticulitis is more common in the young than suggested by previous reports, but the behavior of the disease is not distinctive.

A strategy for intestinal obstruction of peritoneal carcinomatosis.

Obstruction of the small intestine caused by peritoneal carcinomatosis is properly palliated by resection, bypass, and stoma formation. If none of these procedures is applicable, palliation may be achieved by the permanent placement of a long intraluminal decompressive (Baker) tube. Twelve patients have been treated in this manner, nine of them living long enough to exhibit the capacity to eat and drink without repetitive vomiting. The Baker tube was passed across the abdominal wall, inserted into the proximal jejunum, and then passed as far as practical down to the surgically nontreatable obstruction. Venting of the small intestine distally allows continuing decompression, which thereby permits mucosal functions proximally. This technique allows the surgeon to do something beneficial for these unfortunate patients when the established maneuvers of bypass, resection, or stoma formation are pointless.

Influence of individual and group identity salience in the global self-esteem of youth.

Does a content-free measure of global self-esteem tap the same self-esteem dimensions as that measured by self-evaluations on specific dimensions that are then combined into a summated scale? We address this question by using a sample of 1,528 7th, 9th, and 11th graders. Nine specific self-ratings (e.g., "I am smart" and "I am GOOD-LOOKING") were combined into a scale that used various weightings, in an attempt to maximize correlations with global self-esteem measured by two content-free scales. The correlations do not exceed .453, suggesting that measures based on summations of a large number of specific self-ratings tap a somewhat different phenomenon than content-free global scales. The most effective weighting of specific dimensions for predicting global self-esteem depended on group identity salience rather than individual identity salience--that is, group means of the importance of the separate self-evaluation dimensions were used rather than each subject's own self-rating of the importance of that dimension. This result held even when interactive models of weighting were used.

Intraperitoneal polypropylene mesh support of incisional herniorraphy.

Polypropylene mesh (Marlex) is well accepted for use in the peritoneum. Incisional hernias can be effectively repaired by anchoring Marlex intraperitoneally with a series of U sutures. These sutures pass through the normal body wall which remains after excision of the hernia sac and overlying attenuated fascia. When the sutures are taken up, an impenetrable diaphragm of Marlex is drawn into place beneath the abdominal wall defect. The defect itself is closed with other sutures. Only 2 of 25 patients had recurrences, and each recurrence came past the edge of the mesh. This operation is recommended for the repair of incisional hernias.

Endoscopic electrocoagulation: an alternative to operative therapy in bleeding peptic ulcer disease.

Twelve patients with severely bleeding peptic ulcers (six duodenal, five gastric, and one esophageal) who were considered to be at high operative risk were treated instead by endoscopic electrocoagulation of the bleeding point. Arrest of the bleeding was permanent in ten, one bled again two days later, and one patient died of nonulcer disease one day later. Although this method to control bleeding from peptic ulceration is new, it seems to offer promise especially when treating desperately ill people.

Radiomanometric guides to common bile duct exploration.

The accuracy of operative cholangiograms can be increased by radiomanometry. This study identified 17 patients among 198 studied whose choledocholiths would have likely been missed by routine cholangiography. These are almost invariably small stones the fate of which would be conjectural if left behind. In the present study, if the cholangiogram was negative and the passage pressure within normal limits, calculi were seen only once. If the cholangiogram was positive for choledocholithiasis and the passage pressure elevated, stones were almost invariably found (95 per cent). Such accuracy cannot be expected from either roentgenography alone or determination solely of pressure relationships.

Further experience with the Childs-Phillips plication operation.

The Childs-Phillips plication operation was performed in forty-two patients, as treatment for recurrent small bowel obstruction in nineteen and as prophylaxis against future intestinal obstruction in twenty-three. Intestinal obstruction occurred later in only one patient. Eight of ten patients with acute peritonitis died in the postoperative period. Consequently, the operation is not recommended in the presence of generalized acute peritonitis.
