Surgical treatment of displaced olecranon fractures by tension band wiring technique 总被引:2,自引:0,他引:2
G Wolfgang F Burke D Bush J Parenti J Perry B LaFollette S Lillmars 《Clinical orthopaedics and related research》1987,(224):192-204
Forty-five displaced olecranon fractures including 14 accompanying dislocated radial heads and seven radial head fractures were treated over a 13-year period by the tension band wiring technique. The use of supplemental internal fixation when necessary allows excellent results with the use of this technique, even in the presence of severe comminution or radial head dislocation. Primary silicone radial head implants fractured in all three patients in which they were used, necessitating repeat surgery in two patients to date. While loss of motion in terminal extension was a common aftermath of displaced olecranon fracture (59%), it was usually minor and functionally insignificant. True Kirschner-wire migration was not a common problem and can probably be eliminated by proper technique. The presence of gaps in the intraarticular surface of the semilunar notch of the ulna produced no ill effects and was compatible with excellent results. If only those cases with isolated olecranon fractures in this series are considered, there were good and excellent results in 29 of 30 cases (97%). Excision of the olecranon fragment(s) should be reserved for those cases when anatomic restoration cannot be achieved with internal fixation. 相似文献

Results of prevention programs with adolescents 总被引:3,自引:0,他引:3
C L Perry 《Drug and alcohol dependence》1987,20(1):13-19
Programs for preventing smoking and alcohol and drug abuse have radically changed in the past decade. Instead of being regarded as a health or discipline problem that involves only a few deviant adolescents, drug use has begun to be viewed as social behavior that is functional for adolescents, not capricious, and is normative for that population. The most successful prevention programs have sought to delay the onset of tobacco use. Based on theoretical and etiological research, these programs target factors that have repeatedly been predictive of adolescent smoking, alcohol and drug use. The programs teach adolescents (1) why people their age smoke tobacco or use alcohol and drugs; (2) how these meanings get established by peers, older role models and advertising; (3) how to resist these influences to smoke or to use alcohol and drugs; and (4) life skills and competencies to counterbalance the functions that drug use serves. Because of the association with the onset of smoking and the onset of using other drugs, these strategies are being studied for alcohol use and other drugs. In addition, elected peer leaders are trained to conduct these activities with their classmates and act as new role models for non-use. Evaluations of these approaches are optimistic. Studies in northern California and Minnesota reveal 50-70% reductions in the onset of smoking. Botvin's 'Life Skills Training' program demonstrates success in delaying heavy alcohol and marijuana use. 相似文献

A morphological examination of synovial tissue from 25 patients with rheumatoid arthritis revealed that binucleated or multinucleated
plasma cells were present in all samples and absent in synovia obtained from 16 control patients. Plasma cells containing
two, three of four nuclei constitutet a mean 3% of the total plasma cell population. They were aways found amongst plasma
cell infiltrates and in close association with small blood vessels. Ultrastructural analysis found no evidence of cellular
membranes separating the individual nuclei in binucleated or multinucleated plasma cells, suggesting that the cells did not
arise from fusion. Some of these plasma cells had a diameter approaching 100 μm, and many were in intimate contact with macrophages.
The demonstration of a few cells with mitotic figures within the infiltrates suggests that the maintenance of plasma cell
numbers in rheumatoid synovium may depend, in part, upon their local proliferation.

School-Based Cardiovascular Health Promotion: The Child and Adolescent Trial for Cardiovascular Health (CATCH) 总被引:7,自引:0,他引:7
Cheryl L. Perry PhD Elaine J. Stone PhD MPH FASHA Guy S. Parcel PhD FASHA R. Curtis Ellison MD Philip R. Nader MD FASHA Larry S. Webber PhD Russell V. Luepker MD MS 《The Journal of school health》1990,60(8):406-413
The Child and Adolescent Trial for Cardiovascular Health (CATCH) is a multisite intervention research study that builds on significant progress made in school health education research in the 1980s. The study has three phases: Phase I deals with study design, intervention, and measurement development, Phase II involves the main trial in 96 schools in four states, and Phase III focuses on analysis. The intervention program targets third-fifth grade students and focuses on multiple cardiovascular health behaviors, including eating habits, physical activity, and cigarette smoking. Classroom curricula, school environmental change, and family involvement programs are developed for each grade level and behavioral focus. This paper describes Phase II of CATCH with a rationale for cardiovascular health promotion with youth. The process of change that appears to be necessary for school-based health promotion and that will be tested in CATCH are presented as a framework to guide these efforts. 相似文献

Costs and benefits of routine follow-up after curative treatment for endometrial cancer 总被引:6,自引:0,他引:6 下载免费PDF全文
OBJECTIVE: To examine the costs of routine outpatient follow-up after curative treatment of endometrial cancer, and to determine whether this leads to early detection of recurrence or survival. The impact of specific disease characteristics on survival is examined. DESIGN: Retrospective chart review, and calculation of costs. SETTING: Ottawa Regional Cancer Centre-Civic Division (ORCC-C). PATIENTS: All 432 patients referred to the ORCC-C with endometrial cancer between 1982 and 1991 who received treatment with curative intent and who continued with routine follow-up. RESULTS: Cancer recurred in 50 patients (11.57%). There was no statistically significant difference in overall survival between patients with symptomatic and asymptomatic recurrences, or between those with recurrences detected during routine follow-up visits or in the interval between routine visits. Of 4830 Papanicolaou (Pap) smears performed routinely, cancer was detected in 6 cases. The mean cost of the routine follow-up procedures for each patient with a recurrence was $19,200. CONCLUSION: Intensive follow-up of women with endometrial cancer does not result in improved survival. A prospective randomized study is warranted to evaluate other potential benefits of follow-up, such as improved quality of life or decreased morbidity. There is no economic or clinical justification for the routine use of the Pap smear in the follow-up of patients with endometrial cancer. The potential benefits of routine follow-up in endometrial cancer and other types of cancer with favourable prognoses warrant critical evaluation. 相似文献
