Radical anal surgery of the type described for complicated hemorrhoidal and mucosal prolapse has good to excellent anatomic and functional results in 90 per cent of patients. This has been demonstrated in a group of 100 consecutive patients followed for an average of more than two years.

Water beds in use in this hospital were found to be contaminated with Pseudomonas aeruginosa. The addition of sodium hypochlorite, giving a final concentration of 200 parts/10(6) available chlorine, was found to be effective in preventing microbial contamination over a 6-month study period.
Pseudomonas aeruginosa was recovered from three hospital-prepared medicaments being used on the wards. Sixty-six patients were studied to observe the effect of using these contaminated medicaments. Psaeruginosa was recovered from 29 patients; in five the strains recovered bore a close resemblance to strains previously isolated from the contaminated medicaments.
The environments of hospital pharmacies and the preparations made in these pharmacies were examined for Pseudomonas aeruginosa. This organism was widely distributed in the pharmacies and was isolated from 9% of preparations. In 11 instances strains of Ps aeruginosa from the preparations bore a close resemblance to strains previously found in the pharmacy environments.

Intestinal perforation in human immunodeficiency virus-positive patients due solely to Kaposi's sarcoma (KS) has rarely been described. A homosexual man with acquired immunodeficiency syndrome-related KS who presented with an acute abdomen is presented. He was found to have a jejunal perforation through a small KS lesion. There were no infectious organisms identified at the site of perforation.

Surgical technical education has traditionally followed an apprenticeship format. The need for innovative undergraduate programs using dry and wet labs prior to clinical exposure continues to be an area of debate. Specific programs have been described to improve surgical skills; however, an accepted platform for training and evaluation of surgical skills programs has not been recognized. Therefore, introduction of specific programs to teach undergraduate medical students surgical skills is essential. This article describes the Basic Surgical Technique (BST) program taught at the University of British Columbia and reports the effectiveness of this program in improving the practical skills of undergraduate medical students. The program includes BST I for third-year students performed in a dry lab setting, and BST II for medical student interns (MSI) performed at the animal laboratories using female domestic swine as subjects. A total of 87 students participated in the study. The program is designed using Piaget's and Vygotsky's pedagogical philosophy of "learning by doing." A semiquantitative method is used to measure and analyze the outcome of this project. Data were validated using student self-evaluation tests and by quantitative evaluation by surgical staff from the surgical wards. Results of this prospective project indicated that the BST program significantly (p < .05) improved the surgical performance of undergraduate students, and that the time lapse between BST I and II has had a negative impact in retention of acquired surgical skills. This study concludes that the BST program taught at the University of British Columbia significantly improves the surgical skills of medical students and improves their self-confidence during their internship.
