Perforation of an ileostomy by a retained percutaneous endoscopic gastrostomy (PEG) tube bumper.

Percutaneous endoscopic gastrostomy (PEG) has become the procedure of choice for long-term enteral feeding. Complications are generally infrequent and often avoidable. We describe an unusual case in which a PEG tube bumper caused subcutaneous perforation of an ileostomy. After conservative treatment proved unsuccessful, revision of the ileostomy via a peristomal incision was performed, with good result. Caution must be exercised before considering the severance of a PEG tube at the skin, especially in patients with an ileostomy.

The early diagnosis project: a collaborative approach to risk management.

Diagnostic errors account for one-fifth of lawsuits against hospitals and physicians. Virtually all medical specialties are at risk for these lawsuits. To this point, risk managers have done little to assist physicians to reduce their risk of failure-to-diagnose (FTD) lawsuits. This article describes a collaborative effort to reduce FTD lawsuits in the primary care setting.

Breast cancer early detection: differences between African American and white women's health beliefs and detection practices.

PURPOSE/OBJECTIVES: To identify differences in African American and white women's health beliefs and practices regarding early detection of breast cancer. DESIGN AND SETTING: Descriptive survey of educators employed by one public school system in one southern state. SAMPLE: One hundred seventeen African American and 157 white female professional educators. METHODS: Subjects completed a survey questionnaire consisting of investigator-developed items and an adapted version of Champion's Health Belief Model Scales. MAIN OUTCOME MEASURES: Reported frequency of use of mammography, clinical breast examination (CBE), and breast self-examination (BSE); health beliefs about these procedures. FINDINGS: No significant difference in frequency of use of mammography and CBE was found between the two groups. The difference for BSE frequency approached significance (p = 0.058); African American women had performed BSE significantly more times (p = 0.028) than white women during the preceding 12 months. White women had a significantly higher mean score (p = 0.002) for barriers to mammography. The difference between the two groups for barriers to CBE and control with CBE reached the 0.05 level of significance; in both cases, white women had the higher mean score. No significant difference was found in mean scores for beliefs about BSE. CONCLUSIONS: The contribution of health beliefs about breast cancer, mammography, CBE, and BSE to frequency of use of these procedures by race remains unclear. IMPLICATIONS: Efforts to inform women of the need to adopt an early breast cancer detection program should continue. Additional studies are needed to validate present study findings and to expand the knowledge base for healthcare providers.

An interactive perspective on the health beliefs & practices of rural elders.

1. In this study, major themes involving health were closely tied to an affective response of "feeling good" and cognitive appraisal of health status as "being able to function." 2. Rural elderly who participated in the study reported engaging in at least one activity to maintain their health and tended to rely on their own appraisal and resources to manage health problems. 3. Half of the participants indicated a need for services such as blood pressure and diabetic screening, health education classes on diet, cholesterol reduction, hypertension and diabetes management, new therapies in health care, and life management counseling.

Rapid identification of sex in birds by flow cytometry.

A rapid method to identify sex in birds is described. The method requires microliter volumes of blood, and, under appropriate conditions, results can be available within an hour of sample collection. Samples can be stored at 4 degrees C or -20 degrees C without sacrificing the ability to discriminate sex differences in DNA content. The assay will find utility in laboratory, field, and applied studies, in other classes of vertebrates, and in studies on the dynamics of genome size within and among populations.

A reliability study of measures assessing the impact of deinstitutionalization.

This study examined the reliability of several scales and indices used to measure outcome variables (independence, integration, productivity, and satisfaction) among people with developmental disabilities. A stratified random sample of 112 people was interviewed twice in a two-week period and included equal numbers of verbal and nonverbal consumers, of parent versus other caregivers, and consumers with diagnosed level of retardation being dichotomized into high and low. In addition, half of the interviews were test-retest and half were interrater. After stratifying on these four variables, the sample was chosen randomly within subgroups from the total database of 3,700 individuals who receive services through the Developmental Disabilities Services Division of the Oklahoma Department of Human Services. Correlation and proportion agreement analyses were performed on the pre- and post-tests and comparisons made on each scale for each stratification to examine variations in reliability. Acceptable correlations and matched agreements of at least 0.70 for all measures were found, with the Adaptive Development Scale having particularly strong correlations. In addition, responses from people with developmental disabilities on items of the Consumer Satisfaction scale were acceptably reliable.
