Two Puerto Rican families were studied. One family included a number of members with dysfibrinogenemia occasionally associated with hypofibrinogenemia. The second family had members with von Willebrand's disease. The two diseases merged in the proband's immediate family; the affected members of this family exhibited a mild bleeding disorder. Others in the two families had no obvious bleeding tendency. 相似文献

This paper considers the potential outcomes, both positive and negative, of continuing professional development from the perspectives of practitioners and managers. Following a consideration of the literature it draws upon data collected during a 3-year evaluation of the English National Board Framework and Higher Award to highlight divergent views and tensions within Continuing Professional Development (CPD). Considerable discrepancies between practitioners and managers emerge which raise a number of searching questions about the value each group accords to continuing professional development. Based on the data a new framework for conceptualizing the outcomes of CPD is presented which fundamentally undermines a quasi-market approach. 相似文献

The biochemical data and drug histories related to bone disease were extracted from the case records of 47 patients who had been treated by continuous ambulatory peritoneal dialysis (CAPD) for more than two years. These data were reviewed in conjunction with the skeletal surveys done over the same period in all patients, with particular reference to secondary hyperparathyroidism, osteomalacia and non-visceral metastatic calcification. Paired bone biopsies were available in 20 of these patients and the histology was quantitated. In the majority of our patients secondary hyperparathyroidism was controlled or improved on CAPD. Osteomalacia also improved in two of the three patients in whom it was initially present and did not develop in any patient whilst on CAPD. We did, however, note a high incidence of non-visceral metastatic calcification. Small vessel calcification developed in 19.6 per cent of patients, large vessel calcification developed in 23.9 per cent and soft tissue calcification developed in 21.7 per cent of patients. We conclude that CAPD, as a form of treatment for end-stage renal disease, satisfactorily controls the osteodystrophy associated with renal failure in the majority of patients. The significance of the high incidence of non-visceral metastatic calcification remains to be established. 相似文献

An individualized intervention to overcome patient-related barriers to pain management in women with gynecologic cancers 总被引:5,自引:0,他引:5
Concerns about reporting pain and using analgesics ultimately can contribute to poor pain management for many individuals. A nursing intervention to address these "patient-related barriers" was developed based on Johnson's self-regulation theory. The purpose of this pilot study was to determine whether provision of individually tailored sensory and coping information about analgesic side effects and specific information to counter misconceptions would enhance pain management in a sample of 43 women with gynecologic cancers. It was hypothesized that at 1-month post-test and 2-month follow-up, those subjects randomized to the information condition would (a) have lower barriers scores; (b) use more adequate analgesic medication; (c) have lower analgesic side effect scores; (d) have lower pain intensity scores; and (e) experience less pain interference with life and better overall quality of life compared to those in the care-as-usual control group. There was no main effect for group on any of the dependent variables. Rather, all women reported a decrease in barriers between baseline and 2-month follow-up (p<.05); all subjects experienced a decrease in pain interference with life scores between baseline and 1-month post-test (p<.05); and there was a significant shift of women from unacceptable pain management at baseline to acceptable pain management at 1-month post-test (p<.05). In addition, the majority of women reported that the intervention contained novel and useful information that helped them to feel more comfortable taking pain medication, to be less concerned about addiction, and helped them talk more openly about pain with a doctor or nurse. 相似文献
