Equipment dealers' perceptions of a community-based rollover protective structures promotion campaign.

Farming is one of the most hazardous occupations, and tractor overturns are the leading cause of agricultural fatalities. This article examines a community-based injury intervention designed to increase the number of rollover protective structures (ROPS) and seat belts on tractors and to promote safe operation of farm tractors in two counties. Equipment dealers who sell retrofit ROPS kits to farmers were a critical component of the intervention. Interviews were conducted with dealers after the 31-month intervention period to understand their perceptions, any difficulties they experienced as a result of the project and how a similar project could be improved. Comments were analyzed in relation to theories of persuasion. Results indicated that dealers believed the intervention was successful in producing behavior change among some farmers. Dealers also provided important insights into why some farmers continued to resist retrofitting tractors with ROPS. Recommendations are offered for designers of community-based interventions beyond the ROPS project described here.

Sex differences in principal farm operators' tractor driving safety beliefs and behaviors.

OBJECTIVE: To examine the widely accepted hypothesis that farm women are more concerned with safety issues and behaviors than their male counterparts are. METHODS: A telephone survey was administered to a random sample of Kentucky principal farm operators, 90 of whom were women. Participants were questioned about their tractor safety beliefs and practices. RESULTS: No significant sex differences in tractor safety perceptions and behavior were observed. CONCLUSIONS: Socialization of women to the role of principal farm operator may override their typically greater sensitivity to safety issues, an important consideration when designing safety campaigns for this population.

Exophthalmometry: a comparative study of the Naugle and Hertel instruments.

Exophthalmometry is frequently used as a tool in the evaluation of proptosis. The purpose of this study was to compare the clinical usefulness of the newly developed Naugle superior and inferior orbital rim-based exophthalmometer with that of the Hertel exophthalmometer, as well as to obtain normal values and analysis of possible race and sex differences. In the first part of this study, we measured 135 patients in a double-blind study in order to evaluate the repeatability of serial measurements using each instrument. Comfort was also evaluated in this series of patients. In the second part, a single observer measured 205 patients in order to obtain information for a multifaceted analysis. In the first part of the study, we found the Hertel measurement to be more variable in terms of coefficients of variation. We further found the Hertel base measurements to vary more between observers than those of the Naugle instrument. In the second part, we found that the mean values of globe position were not statistically different (mean Naugle, 17.23; mean Hertel, 18.61; p = 0.909). A significant difference was noted between black and white patients when using the Naugle instrument. A difference between white and black women was noted with the Hertel instrument. The results of this analysis strongly suggest that the values obtained from the Naugle exophthalmometer are more repeatable in serial measurements compared with the Hertel values. However, single measurements of globe position from all patients were statistically similar. We conclude that the Naugle instrument is comparable in accuracy to the Hertel instrument for measuring ocular position, as well as being more comfortable for the patient. The Naugle instrument has the advantage of measuring hyperophthalmos and hypoophthalmos with a vertical gradient scale.

Brown recluse spider envenomation of the eyelid: an animal model.

The authors developed a rabbit model of the brown recluse (BR) spider envenomation of the human eyelid. The spider bite causes cutaneous necrosis and systemic toxicity in human eyelids, possibly leading to disseminated intravascular coagulation, hemolysis, and death. The treatment has been controversial. The animal model evaluated the effects of single- and combined-agent therapy in four phases: venom dose response, time course, therapeutic effectiveness (steroid vs. dapsone vs. antivenom), and optimal therapy (steroid and dapsone; steroid and antivenom; and dapsone and antivenom combination groups). The combination dapsone and antivenom treatment group was the optimal animal regimen, although not completely effective in eliminating microscopic necrosis. The authors also report dramatic clinical improvement in human inflammatory response with dapsone therapy and recommend immediate dapsone therapy combined with specific BR venom, if available, in humans.

Harada's disease associated with fibrous dysplasia.

Harada's disease is a well-described entity consisting of bilateral serous retinal detachments and diffuse choroiditis. The etiology of Harada's disease is obscure. Fibrous dysplasia of the orbit is also a well-known entity associated with many orbital and ophthalmologic findings. The defect in fibrous dysplasia appears to be a congenital nonhereditary abnormality in bone-forming mesenchyme. We present a case of Harada's disease and fibrous dysplasia of the orbit. The clinical photographs, fluorescein angiograms, ultrasound study, and histologic specimens are presented.

Motivational factors in the careers of health care educators.

Little formal research attempts to relate personnel and job-role characteristics with motivations and satisfactions in the health care education field. This paper reports findings, based on a national multidisciplinary sample of health care educators (N = 229), that argue against cynical appraisals of motivations, job satisfactions, and job-role compatibility. A number of empirical hypotheses are derived that may serve as starting points for further inquiry. Instruments and methods useful for future research are described.

Embedded performance measures as teaching and assessment devices.

Standard methods of testing trainees during courses on health and safety are time-consuming and, therefore, testing is rarely completed. Embedded performance measures, however, offer an alternative to traditional testing; they are completely integrated with instruction and require the learner to perform numerous short problem-solving tasks. The author focuses on the history of embedded performance measures and their effectiveness in health and safety training.
