Immunochemical testing for faecal occult blood in patients with colorectal cancer.

Eighty-six stool specimens collected from 36 patients with colorectal cancer were tested for occult blood by chemical and immunochemical methods. There was no dietary restriction. Positive results were obtained in 94% of patients by the immunochemical method when the presence of any positive immunochemical test was taken as a positive result. If greater than 1 mg of haemoglobin per gram of faeces was regarded as positive result, then 75% of patients would have been diagnosed as having occult blood in the stool by means of the immunochemical method. Positivity rates for Hemoccult II and rehydrated Hemoccult II were 53% and 81%, respectively.

A student emergency medicine clerkship that uses new information technologies.

The effective teaching of clinical emergency medicine to medical students requires efficiency in the management of both student and faculty time. Presented is a course outline that makes use of the following elements to structure and augment clinical time in the emergency department (ED): Videotape to present a 19.7-hour series of faculty-produced lectures covering a "core" emergency medicine curriculum. A microcomputer to facilitate staggered scheduling of clinical time. A microcomputer test generation program that permits a secretary to formulate, administer, and grade a different final exam with each rotation. Computer-assisted recordkeeping for faculty evaluation of a student's clinical performance. Once established, this program can be administered with fewer than five faculty hours per month assisted by a part-time (25% full-time equivalent) clerical coordinator. The total cost for the instructional program is $86.37 per student using the new technologies, and $144.15 per student when presenting the same program using traditional teaching techniques. The use of new technologies in student teaching will therefore result in significant savings.

Serum factor affecting neutrophil function during acute viral hepatitis.

Sera from eight of 17 patients with acute viral hepatitis was deficient in its ability to support neutrophil bactericidal function in vitro. This defect appeared to be related to the viral infection itself. Sera from patients with drug hepatitis or mechanical obstructive jaundice did not show this effect.

Credibility ratings for desensitization and pseudotherapy among moderately and mildly snake-avoidant college students.

Twenty moderately avoidant and 20 mildly avoidant Ss were chosen as though they were to participate in a snake-avoidance desensitization experiment. After relaxation training, Ss listened to a taped excerpt of either desensitization or pseudotherapy and responded to a 5-item questionnaire that assessed the credibility of the treatment. Mildly avoidant Ss rated desensitization as more credible than pseudotherapy. The implication of this finding is that a great many experimental studies of systematic desensitization have failed to control satisfactorily for the operation of expectancy effects and nonspecific forms of behavioral influence.

The importance of an annual report.

An annual report, by summarizing the emergency department's accomplishments, is an effective means of highlighting the vital role of the emergency department within the hospital system and the community. The report should begin with an Executive Summary and proceed to detail the clinical, educational, research, administrative, financial, and other essential aspects of the status and development of the department.
