OBJECTIVE: The objective of this study was to examine the true-positive rates by level of training of the operator and to determine whether the accuracy of the procedure differed by the level of education after formalized training. STUDY DESIGN: This was a retrospective analysis. The records of patients who underwent surgery for the indication of an abnormal saline sonohysterography were reviewed from January 2001 to April 2003 (n=73 patients). The nature of the saline sonohysterography abnormality, the intraoperative findings, and the level of training of the provider were recorded. Findings at saline sonohysterography were compared with findings at hysteroscopy or surgery. Statistical significance was determined by chi(2) test. RESULTS: The overall true-positive rate was 86.3% (63/73 patients). The true-positive rates for nurse practitioners, second- and fourth-year residents, and fellows were 84%, 80%, 90%, and 89%, respectively. There was no significant difference among providers (P=.96). CONCLUSION: The true-positive rates for saline hysterography were comparable among different provider levels. 相似文献

At the present time approximately 1 in 1000 young people aged between 16 and 35 years will have been cured of cancer in childhood and some of the treatment regimens used will have predictable effects on their future fertility prospects. In young women who have been exposed to radiotherapy below the diaphragm, the reproductive problems include the risk of ovarian failure and significantly impaired development of the uterus. The magnitude of the risk is related to the radiation field, total dose and fractionation schedule. Premature labour and low birth weight infants have been reported after flank abdominal radiotherapy. Female long-term survivors treated with total body irradiation and marrow transplantation are also at risk of ovarian follicular depletion and impaired uterine growth and blood flow, and of early pregnancy loss and premature labour if pregnancy is achieved. Despite standard oestrogen replacement, the uterus of these young girls is often reduced to 40% of normal adult size. Uterine volume correlates with the age at which radiation was received. Regrettably, it is likely that radiation damage to the uterine musculature and vasculature adversely affects prospects for pregnancy in these women. It has been demonstrated that, in women treated with total body irradiation, sex steroid replacement in physiological doses significantly increases uterine volume and endometrial thickness, as well as re-establishing uterine blood flow. However, it is not known whether standard regimens of oestrogen replacement therapy are sufficient to facilitate uterine growth in adolescent women treated with total body irradiation in childhood. Even if the uterus is able to respond to exogenous sex steroid stimulation, and appropriate assisted reproductive technologies are available, a successful pregnancy outcome is by no means ensured. The uterine factor remains a concern and women who are survivors of childhood cancer and their carers must recognize that these pregnancies will be at high risk. 相似文献

The increased rates of twinning and the increased consumption of folic acid are two parallel processes described in recent years. However, the possible association between an increased incidence of twin pregnancies and periconceptional folic acid supplementation remains controversial. Whereas the data indicating that when folic acid levels are increased to the range required for reducing the incidence of neural tube defects, the data pertaining to the increase in twinning rate are significantly incoherent and are flawed by serious confounders, such as fertility treatments and maternal age. The only plausible theory connecting methyltetrahydrofolate reductase mutation, folic acid, and twinning has not been confirmed. In addition, temporal and dose-effect relationships have not been established. Because of the lack of coherence, questionable plausibility, and no clear dose-effect and temporal relationships, a cause (folic acid supplementation) and effect (increased twinning rate) association cannot be, at present, accepted. Thus, the established policy of peri-conceptional folic acid supplementation to reduce the incidence of neural tube defects should be continued. 相似文献

OBJECTIVE: To assess whether the way in which women experience the onset of their labour influences the duration of their labour. DESIGN: Longitudinal study on a convenient sample of women in spontaneous labour with a singleton pregnancy in cephalic presentation at term. SETTING: University hospital in Germany. POPULATION/SAMPLE: Six hundred and fifty-one women (347 primiparae and 304 parae). METHODS: Women recorded how and when labour had started. Responses were subjected to structured content analysis. Two investigators independently subdivided women's reported signs and symptoms into eight predefined categories. These data were related to maternal characteristics and to the course and outcome of labour as documented in the perinatal record. MAIN OUTCOME MEASURES: Women's perception of how labour had started, interval between onset of labour and rupture of the membranes and duration of first stage labour and overall duration of labour. RESULTS: Only 60% of women reported contractions as a sign of the onset of their labour. These women had a longer interval between the onset of labour and rupture of the membranes but a similar duration of labour when compared with women who did not report contractions as a sign of the onset of labour. Self-reported loss of amniotic fluid was the only sign that showed a consistent relationship with the duration of labour. Other patterns of labour onset had no effect on the duration of labour. CONCLUSION: Irrespective of whether they have given birth before, women experience their onset of labour in a variety of ways. A large proportion of these experiences bear no resemblance to the classical diagnosis of labour and most are unrelated to the duration of labour. 相似文献

OBJECTIVE: Mediolateral episiotomy is associated with lower rates of significant perineal tears than midline episiotomy. However, the relationship between precise angle of episiotomy from the perineal midline and risk of third-degree tear has not been established. This study quantifies this relationship. DESIGN: Case-control study. SETTING: National Maternity Hospital, Dublin, Ireland. SAMPLE: One hundred primiparous women who had undergone right mediolateral episiotomy 3 months previously. METHODS: Two groups of primiparous women were compared. Cases had sustained clinically apparent anal sphincter injury during delivery, while controls had not. The angle of episiotomy measured from the midline was marked on a superimposed sheet of transparent plastic film and measured using a protractor. Data were analysed using Student's t test, chi-square test and logistic regression analysis. MAIN OUTCOME MEASURES: Angle of mediolateral episiotomy from the perineal midline. RESULTS: Fifty-four cases and 46 controls were assessed. Cases were more likely to have undergone assisted delivery and consequently to have been delivered by an obstetrician than by a midwife. The mean angle of episiotomy measured significantly smaller in cases (30 degrees, 95% CI 28-32 degrees) than in controls (38 degrees, 95% CI 35-41 degrees; P<0.001). Analysis showed a 50% relative reduction in risk of sustaining third-degree tear for every 6 degrees away from the perineal midline that an episiotomy was cut. CONCLUSIONS: These results show that a larger angle of episiotomy is associated with a lower risk of third-degree tear and mediolateral episiotomy incisions should be made at as large an angle as possible to minimise the risk of sphincter disruption. 相似文献

Polycystic ovary syndrome (PCOS) is a syndrome involving defects in primary cellular control mechanisms that result in the expression of chronic anovulation and hyperandrogenism. In this syndrome the relation between the various parameters is of particular interest. These relations constitute the cornerstone of the pathogenesis of PCOS. The fact that the pathogenesis of the PCOS has not yet been clarified, despite the plethora of relative information, may be the result of a general way of thinking in the interpretation of several scientific data, and especially those that refer to biochemical phenomena. The use of the various models of the theory of chaos, that permits a concrete approach for the interpretation of data, may constitute an optional procedure for the future understanding of the association of different parameters and their disturbances in the pathogenesis of PCOS. 相似文献

ObjectivesThis study examined the impact of the COVID-19 pandemic on the experience, practice and future of Reiki in the UK, including the personal impact of the pandemic on practitioners and their work, practitioner perceptions of the future of the profession and Reiki delivery, and practitioner experiences and views of distant Reiki in comparison to hands on or near the body treatments.MethodA qualitative study using semi-structured interviews was carried out with 10 Reiki practitioners. Interviews were recorded, transcribed verbatim and analysed using thematic analysis.ResultsThree themes were identified: adapting and growing with the challenges of COVID-19, Reiki for individual and community resilience, and moving from the mainstream hands on to lesser known distant Reiki.ConclusionWhile the COVID-19 pandemic personally impacted Reiki practitioners, they focused on turning adversity into opportunity, to overcome a sense of disconnectedness and social isolation, by providing social support and promoting individual and community resilience. Practitioners focused on self-care, personal development and reaching out to the community. Personal Protective Equipment was perceived as necessary for infection control but a potential barrier to the client's experience of Reiki. They saw value in adapting their practice as part of the future of the profession by utilising new technology and distant Reiki healing, but were clear this could not replace in person contact. 相似文献

In the paper, the mature newborns of women over 40 were compared to the mature ones of young mothers. The babies were born in the Institute of Gynecology and Obstetrics in Lód?, in the years 1997-1998, and the comparison was done by the analysis of some neonatal parameters. The newborns of older women were delivered by cesarean section mainly. The birth weights average of the index babies was lower than the birth weights average of the controlled ones. Some clinical parameters in both analysed groups were similar. The most important difference concerned the congenital malformations and intrauterine hypotrophy--these disorders were clearly more frequent among the newborns of older mothers. 相似文献
