Effects of fibrin glue on injured rabbit ureter.

BACKGROUND AND OBJECTIVE: Fibrin glue is used as a hemostatic agent, has potential as a tissue adhesive, and may promote tissue healing. The histologic effects of fibrin glue on the ureter have not yet been fully investigated. We studied the effect of fibrin glue on the thickness of various layers of injured and uninjured ureters and its effect on vessel density in the rabbit model. MATERIALS AND METHODS: Rabbits were divided into two groups. The ureters were exposed using a midline abdominal incision. In the study group, one of the ureters was crushed, and fibrin glue was instilled around both ureters. In the control group, one of the ureters was crushed, but no fibrin glue was instilled. The animals were sacrificed at 6 weeks and the ureters examined histologically. Using NIH Image Analysis solftware, the thickness of the urothelium, muscular, and adventitial layers and the cross-sectional area of the ureters were measured. The vessel density of the ureters was also assessed. RESULTS: Whereas the thickness of the epithelium was increased in the crushed ureters treated with fibrin glue (20.7 microm v 15.3 microm), the thickness was reduced in the uncrushed ureters treated with fibrin glue compared with controls (16.3 microm v 19.8 microm). There was no statistically significant difference in the thickness of the muscular or adventitial layers in the study and control groups. There was a reduction in the cross-sectional area of the uncrushed ureters treated with fibrin glue compared with controls (7,095 microm2 v 9,409 microm2). In addition, the vessel density in the crushed ureters was reduced in ureters treated with fibrin glue compared with controls (0.00067/microm2 v 0.00108/micro2). In the uncrushed ureters, the difference was not statistically significant. CONCLUSIONS: Fibrin glue has potential as an adhesive agent in the ureter and may promote healing. It may affect epithelial layer thickness and vessel density of the ureter, but these effects were variable. Fibrin glue does not appear to have significant effects on the ureteral muscular and adventitial layers or on the overall cross-sectional area of all three layers. These results indicate that fibrin glue does not appear to have a detrimental effect on the ureter.

A comparison of craft use and academic preparation in craft modalities.

The purpose of this study was to compare the use of crafts in psychiatric occupational therapy practice with the actual craft-related training received by occupational therapy students. Two questionnaires were developed, one related to the crafts used in clinical practice, the other related to the amount and type of craft training received in educational programs. One thousand occupational therapists who work in psychiatry and 139 accredited and developing educational programs were asked to complete the questionnaire appropriate to their setting. The final analysis involved 121 educational programs (87% response rate) and 384 clinical programs (38% response rate). The results suggest that there may be substantial differences between craft-related training and actual clinical use of crafts. The findings imply that educational programs must reevaluate the types of crafts taught and the method by which they are integrated into the total curriculum. Implications for the profession include the need to clarify the role of crafts as a therapeutic modality and to reflect on the future direction of the profession.

Evaluating productivity and profitability in occupational therapy contractual work.

The availability of contractual work for occupational therapists is increasing steadily. Because of time constraints, therapists often must select one contract over another. To help the therapist make informed decisions, this paper provides a step-by-step process for developing a trend analysis to compare the productivity and profitability of contracts. A case example taken from the author's own experience illustrates this process.

Developing a variable budget for occupational therapy contract work.

Contract occupational therapists need to develop a financial plan for improved control of their business. The variable budget allows financial planning according to actual performance volume. This paper describes a step-by-step method for the development of a variable budget through the illustration of a case example.
