Gastric emptying, CCK release, and satiety in weight-stable obese subjects.

Scintigraphic gastric emptying studies are far from conclusive in obesity. The aim was to investigate gastric emptying and CCK release in weight-stable obese subjects on their usual diet and to study the impact of factors known to determine gastric emptying. Patients entering a weight reduction program were asked to participate in a study examining gastric emptying by scintigraphy and CCK release in response to a meal with questionnaires on feelings of satiety.

Open reduction and internal fixation of three and four-part fractures of the proximal part of the humerus.

Background: Controversy persists concerning the preferred treatment of displaced fractures of the proximal part of the humerus. The present study was undertaken to evaluate the results of open reduction and internal fixation of three and four-part fractures of the proximal part of the humerus and the functional limitations of patients in whom avascular necrosis of the humeral head develops as a complication of this fracture.

Methods: We assessed the intermediate and long-term results for sixty patients with a three or four-part fracture of the proximal part of the humerus who had undergone open reduction and internal fixation with cerclage wires or a T-plate.

Results of a prospective randomised study comparing a non-invasive surgical zipper versus intracutaneous sutures for wound closure.

A prospective randomised study was undertaken to investigate the advantages and disadvantages of a non-invasive surgical zipper (Medizip) vs intracutaneous sutures skin closure in orthopaedic surgery. The study group consisted of 120 consecutive patients, 45 men and 75 women with a mean age of 47 years. The Medizip was used in 20 surgical knee wounds, 20 hip wounds and 20 orthopaedic spine wounds.

The Gore-Tex prosthetic ligament as a salvage procedure in deficient knees.

The purpose of this study was to evaluate the results of prosthetic ligament replacement of the anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) with the Gore-Tex polytetrafluorethyene prosthesis (W.L. Gore and Co.
