OBJECTIVE: Antenatal perineal massage has been shown to reduce the incidence of perineal tears in primiparous women. The aim of this study was to determine whether perineal massage impacts on primary prevention of symptomatic disruption of the fecal continence mechanism. METHODS: An observational study recruited two cohorts of women. The first, massage group (MG) chose to perform daily perineal massage from 34 weeks gestation, and the second, control group (CG) was asked to avoid massage. Perineal injury and postnatal pain were documented and all women were invited to attend at three months postpartum for continence assessment, anal manometry, and endoanal ultrasound. RESULTS: Of 179 women recruited, 100 were in the MG while 79 women were controls. Mode of delivery was not influenced by perineal massage. Although the impact did not reach statistical significance, women aged over 30 years in the MG were more likely to be delivered with an intact perineum than controls. Postnatal perineal pain was much reduced in the MG compared with the CG (p = 0.029). Of the women recruited, 136 (75.9%) returned for a postnatal continence assessment. Manometry pressures, continence scores, and endoanal ultrasound findings were similar in both groups. CONCLUSION: Antenatal perineal massage was found to significantly affect postnatal perineal pain scores although it did not impact on the incidence of intact perineum at delivery, postnatal continence scores, anal manometry pressures, or endoanal ultrasound findings. 相似文献

(1) The methylxanthine caffeine has many pharmacological effects, most of which can be linked to blockade of adenosine receptors, inhibition of phosphodiesterases, and augmentation of calcium-dependent release of calcium from intracellular stores. (2) A variety of xanthines have been developed as potent and/or selective antagonists for adenosine receptors. (3) Several xanthines have been developed that are more potent and more selective inhibitors of cyclic nucleotide phosphodiesterase than caffeine or theophylline. (4) Caffeine remains the xanthine of choice for activation of intracellular calcium-sensitive calcium release channels although millimolar concentrations are required, which can have effects on other aspects of calcium regulation. 相似文献

There is a well‐documented shortage of physician researchers, and numerous training programs have been launched to facilitate development of new physician scientists. Short‐term research training programs are the most practical form of research exposure for most medical students, and the summer between their first and second years of medical school is generally the longest period they can devote solely to research. The goal of short‐term training programs is to whet the students’ appetite for research and spark their interest in the field. Relatively little research has been done to test the effectiveness of short‐term research training programs. In an effort to examine short‐term effects of three different NIH‐funded summer research training programs for medical students, we assessed the trainees’ (N = 75) research self‐efficacy prior to and after the programs using an 11‐item scale. These hands‐on training programs combined experiential, didactic, and mentoring elements. The students demonstrated a significant increase in their self‐efficacy for research. Trainees’ gender, ranking of their school, type of research, and specific content of research project did not predict improvement. Effect sizes for different types of items on the scale varied, with the largest gain seen in research methodology and communication of study findings. 相似文献
