A comparison of a disposable skin stapler and nylon sutures for wound closure.

A disposable skin stapler (Proximate; Ethicon) was compared with conventional nylon sutures in respect of time taken for wound closure, cosmetic result and ease of application and removal. It was found that a time saving of 80% is possible with the stapling device, and that the cosmetic result with staples is as good as if not better than that with nylon sutures. A certain amount of experience and practice facilitates the use of the stapler.

Kinetics and fate of indium 111 oxine-labeled platelets in patients with aortic aneurysms.

The survival and sites of sequestration of indium 111 oxine-labeled autologous platelets were studied quantitatively in six patients with aortic aneurysms. The in vivo distribution was quantitated daily with a scintillation camera and a computer-assisted imaging system. Data of platelet survival curves were fitted to a gamma function model. Mean platelet survival was shortened and the disappearance curves were exponential in all but two patients who had normal platelet survival. Platelet radioactivity in the aneurysm was 5.1 +/- 3% of whole-body radioactivity at the end of platelet survival. Platelet were sequestered in the spleen, liver, and bone marrow. Accumulation of platelets, presumably due to microembolization, was prominent in the lower limbs. This indicates that although platelets were deposited in the aneurysm, many are damaged and are eventually sequestered in the reticuloendothelial system.

Wermer's syndrome. A case report.

Wermer's syndrome (or multiple endocrine adenomatosis type I) is a hereditary condition characterized by tumours or hyperplasia involving multiple endocrine organs. Most commonly the pituitary and parathyroid glands and the pancreas are involved. We record a further case, the patient presenting with acromegaly due to a pituitary adenoma, hypercalcaemia due to a parathyroid adenoma and peptic ulceration.

[Appendicitis in the Black population].

In this retrospective study important aspects of appendicitis in 252 Blacks were studied and some interesting conclusions were drawn from clinical and operative data. Certain widely accepted impressions and beliefs are substantiated and others are refuted by the evidence found. In 38% of patients see, symptoms were present for more than 4 days before admission, but the clinical picture corresponded remarkably well with the textbook description. Operative findings revealed a diagnostic error rate of 18%, and the eventual mortality of 2% was confined to the 1st and 5th decades.

[Aspects of the treatment of postoperative oliguria].

The importance and differential diagnosis of postoperative oliguria are discussed. A plea is made for the recognition of undesired postoperative antidiuretic hormone (ADH) secretion as a separate entity in the aetiology of postoperative oliguria. Five patients are described who suffered from postoperative oliguria and in whom the diagnosis of undesired ADH secretion was made. The successful treatment of this condition with diphenylhydantoin is emphasized.

[Anesthesia for patients with intestinal obstruction].

The pre- and intra-operative care of patients with acute intestinal obstruction is reviewed. The most important pre-operative problems are hypovolaemia, sepsis, electrolyte and acid-base imbalances. The evaulation and treatment of these disorders are discussed. The importance of preventing regurgitation and inhalation of stomach contents is emphasised and the methods which are used are described. The safest techniques of induction and maintenance of anaesthesia as well as muscle relaxation and intra-operative fluid therapy are indicated.
