OBJECTIVE: To examine factors that affect pelvic muscle response to 12 weeks of pelvic muscle exercise. DESIGN: Repeated measures design in which intravaginal pressures during pelvic muscle contractions were recorded at baseline and after four exercise levels. SETTING: College of Nursing research site in Gainesville, Florida. PARTICIPANTS: Eighty-five parous, community-dwelling women, aged 35-78 years and without incontinence as a primary concern. INTERVENTIONS: A 12-week graded program of regular (three times per week, every other day) pelvic muscle exercise at home. MAIN OUTCOME MEASURES: The hypotheses were that younger age, lower parity, higher baseline intravaginal pressures, and adherence to the pelvic muscle exercise program each would result in significant improvement in maximum intravaginal pressures. RESULTS: The only factor showing significance in predicting a successful outcome was age (t = -2.29, df = 41, one-tail probability = .0136). CONCLUSIONS: Regular, graded exercise over several weeks is needed to build pelvic muscles, and some women who exercise do not improve. Although the reasons for not improving are unclear, age is a significant factor. 相似文献

Objective : To evaluate varying CT settings to visualize pediatric vascular stents in comparison to digital angiography (DA). Background : There is a great clinical interest in substituting noninvasive methods to follow up children with congenital heart disease after interventional treatment. Materials and Methods : CT studies in small children with transcatheter placed stents were reviewed, retrospectively. Furthermore, eight stents were implanted in tubes and partially obstructed. CT exams were performed on varying scanners (4 up to 64 slices) with corresponding tube settings. The effects of dose on image quality were evaluated regarding stent size, strut thickness, and in‐stent stenoses in comparison to DA. Results : Fourteen children with 28 implanted stents were identified. Significant differences between higher and lower radiation settings were not found, corresponding with the phantom, where moderate tube setting showed the best results. In vitro, there was an improvement with increasing number of detector rows, which resulted in a decrease of stent strut overestimation (295% down to 201%; P < 0.0001) and a better agreement with DA measurements for mild (78% up to 91%; P = 0.003) and moderate in‐stent stenoses (80% up to 99%; P = 0.0001). Conclusion : Higher radiation exposure settings did not improve image quality, suggesting that the exams could be performed at a lower radiation dose. © 2008 Wiley‐Liss, Inc. 相似文献

Background
The primary aim of axillary reverse mapping (ARM) is to prevent lymphedema by preserving arm versus breast axillary lymphatics. Concerns regarding feasibility and oncologic safety have limited the adoption of the technique. This prospective study was undertaken to investigate ARM in clinically node negative and node positive breast cancer patients.Methods
A total of 184 patients underwent 212 ARM procedures: 155 sentinel lymph node biopsies (SLNB) without axillary lymph node dissection (ALND) (group 1) and 57 ALNDs with/without SLNB (group 2). ARM lymphatics were not preserved if they were a SLN, directly entered a SLN, or were within ALND boundaries during ALND.Results
SLN with radioisotope alone was successful in 92 % of procedures (181 of 197). ARM identification was 47 % (73 of 155) in group 1. Criteria were met in 30 % (47 of 155) for preservation, and 25 % (38 of 155) were preserved. Of those who met preservation criteria, 81 % (38 of 47) were preserved. In group 2, ARM identification was 72 % (41 of 57); 7 met criteria for preservation and were preserved. Of the ARM nodes, 10 % (22 of 212) were SLNs (crossover). ARM nodes contained metastatic disease in one crossover and two nonsentinel ARM nodes in clinically node positive patients with N2/N3 disease.Conclusions
ARM is a feasible technique for identification and preservation of axillary arm lymphatics with an acceptable incidence of SLN crossover. A larger sample size is needed to determine if ARM can reduce the incidence of lymphedema in patients undergoing SLNB alone and to confirm the absence of ARM metastases in clinically node negative patients undergoing ALND. 相似文献10.
