A primary intrascrotal mass clinically mimicking a testicular tumor was found to be a desmoid tumor originating from the spermatic cord. To our knowledge, this is the first reported case of a paratesticular desmoid tumor. 相似文献

Because there is a 35 to 50 percent incidence of false-positive prediction of fetal compromise on fetal heart-rate monitoring patterns, many unnecessary cesarean sections are performed. To reduce the number of unnecessary cesarean sections, the physician is urged to consider the following: (1) fetal heart-rate monitoring is associated with higher rates of cesarean sections than in those not monitored; (2) only high-risk patients should be monitored provided the low-risk patient is at term, with a normal-sized infant, and does not convert to a high-risk patient while in labor; (3) maintenance of variability is a better predictor of absence of acidosis than is fetal scalp pH; (4) fetal scalp stimulation by firm digital pressure or gentle nontraumatic clamping of scalp tissue or acoustic stimulation obviates the need for fetal scalp pH confirmation of acidosis in 50 percent of cases; (5) monetary considerations may unconsciously lead to increased cesarean sections, since insurance companies remunerate at a higher level for those as compared with vaginal deliveries; and (6) more patients with prior cesarean section should be given a trial of labor, since the initial reason for cesarean section often is not a recurring one and many could successfully be delivered vaginally. Ultimately there is a risk inherent in any decision regarding method of delivery. The patient must understand this risk and share in the decision-making process as a knowledgeable person, aware of the limitation of her physician. 相似文献

This research applied the life table technique to nursing personnel data in two types of hospitals to illustrate how administrators can examine patterns of continued employment. Although a large proportion of nurses were short-stay employees, the teaching hospital was found to have a higher retention rate than the community hospital corporation. The retention patterns are examined by personal and professional characteristics, as well as by reason for termination. Implications of our findings are discussed with respect to policy concerns related to hiring, retention, productivity, and staff development. 相似文献

The effect of steroids on peripheral blood lymphocytes containing parallel tubular arrays. 总被引:3,自引:3,他引:3 下载免费PDF全文
The response of lymphocytes containing cytoplasmic inclusions called parallel tubular arrays (PTA) was determined after the administration of the glucocorticoid dexamethasone to 10 healthy volunteers. The percentage of these lymphocytes was found to increase during the lymphopenia induced by steroid administration. The size and number of parallel tubular arrays per cell showed no differences before and after steroid administration, indicating that the increase was a result of a change in the proportion of whole cells. This indicates, for the first time, that a morphologically defined population of lymphocytes from the normal peripheral circulation has been linked to a specific response, ie, steroid resistance. The possible mechanism of steroid resistance is discussed. 相似文献
