The need for a revival of psychoanalytic investigations into premature ejaculation

Although psychoanalysis was the first-choice treatment for premature ejaculation (PE) between 1920 and 1960, hardly any reports on its efficacy have been published. Moreover, a scientific debate about its findings has never been fully developed. The recent progress that has been made in the classification of three different PE syndromes creates a new opportunity for psychoanalytic investigations of men with complaints of PE, distinguished by the actual duration of their intravaginal ejaculation latency time (IELT). The term premature-like ejaculatory dysfunction has been introduced to distinguish men with self-perceived PE at normal and long IELT durations from those men with lifelong, acquired and normal variable PE. Psychoanalytic research may contribute to a better understanding of the consequences of objective early ejaculations on the unconscious mental life of men with the four forms of PE. By integrating neurobiological, clinical and epidemiological data of ejaculatory performance, a revival of psychoanalytic research of PE in the four distinct, classified PE groups, will probably contribute to a deeper insight in to the unconscious mental life of men affected by PE.     

孕足月胎膜早破与头位难产的相关性

目的：探讨足月妊娠胎膜早破与难产的关系。方法：选择262例足月妊娠胎膜早破患者作为观察组,另随机抽取本院同期262例无胎膜早破的健康孕妇作为对照组,比较两组难产率的发生情况。结果：观察组难产率为45.0%,明显高于对照组的22.9%（P〈0.01）。两组的难产因素差异无统计学意义（P〉0.05）。结论：胎膜早破与难产有相关性,应及早处理,防止母儿并发症的发生。     

新生儿窒息124例临床分析

目的探讨预防新生儿窒息的措施，以降低新生儿窒息的发生率。方法收集我院124例新生儿窒息的临床资料，分析发病的相关高危因素。结果窒息的相关因素依次为：早产因素34例居首位，占27．4％；羊水过少占14．5％；胎位异常占10．5％；产程异常占9．7％；脐带因素（缠绕、脱垂及过短）占8．9％；巨大儿占8．9％；胎盘早剥及前置胎盘占6．5％；妊娠高血压综合征占5．6％；宫内生长迟缓（IUGR）占3．2％。结论加大孕产妇分级管理的力度，加强孕期保健和产前检查，适时纠正臀位，尽量减少早产，及早发现和正确处理胎儿宫内窘迫，是降低新生儿重度窒息的有效措施。     

Pulmonary effects of closure of patent ductus arteriosus in premature infants with severe respiratory distress syndrome

The pulmonary effects of closure of a patent ductus arteriosus (PDA) were investigated in 11 premature infants with severe respiratory distress syndrome. Successful closure of a PDA did not improve the short-term severity of pulmonary disease (24 and 48 h after treatment) as judged by the arterial/alveolar oxygen tension ratio or the amount of ventilatory support. Also, pulmonary mechanics measured 24 h before, 24 and 48 h after treatment, were not statistically different.Conclusion Infants with severe respiratory disease requiring high ventilation pressure and high oxygen concentration, where structural changes in the lungs are already established, will rarely show short-term improvement in pulmonary disease as a result of closure of a PDA. The overall clinical condition may, however, improve as a result of reduced cardiovascular strain. Earlier treatment of a PDA could reduce the ventilation period and the possible risk of developing chronic lung disease.     

The epidemiology of bacteriuria in pregnancy

Bacteriuria in pregnancy is now easily detected by various techniques adapted to the office setting. It is importtant to screen for bacteriuria in pregnancy because 3%–10% of pregnant women will be positive for occult infection. Up to 30% thus infected will subsequently develop pyelonephritis later in pregnancy, which in turn is associated with premature labor and delivery. This entity must be detected and treated as early as possible in pregnancy to prevent these adverse effects.Presented at the Zambon Symposium on Bacteriuria in Pregnancy, International Urogynecological Association Annual Meeting, Riva del Garda, Italy, September 13, 1989.Dedicated to the memory of Edward H.

296例胎膜早破的临床分析

以２９６例胎膜早破（ＰＲＯＭ）作为研究对象，并以３５０例无ＰＲＯＭ作对照，探讨ＰＲＯＭ对母婴的影响。结果显示：ＰＲＯＭ组难产率为５６．０８％，产褥病率４．０５％，早产率为５．４０％，胎儿窘迫率为１３．００％，新生儿窒息率为４．３３％，新生儿肺炎发生率为３．６６％，均明显高于对照组，统计学处理后有显著或极显著性差异（Ｐ＜０．０５，Ｐ＜０．０１）。而且，ＰＲＯＭ隐惹期小于２４小时的产褥病率为２．２９％；大于２４小时的产褥病率则为８．９７％（Ｐ＜０．０５）。本文提示，应积极预防胎膜早破，一旦出现胎膜早破，宜在６小时内使用抗生素预防感染，并加强母儿监测。     

Follow up of growth and steroids in premature adrenarche

In a follow up study of 34 patients with premature adrenarche we examined serum adrenal androgen levels and growth. The majority (28/34) showed an upward bend in the growth curve which, at the mean age of 2.3 years, preceded other signs of adrenarche on average by 3.8 years. Pubertal growth spurt was missing or reduced in 50% of the patients (8/16), however, final height did not differ from that expected from parental heights. Adrenal androgens did not remain elevated at adolescence. The mean age at menarche for all the girls was 0.5 years younger than in the general population.Conclusion Our findings imply that premature adrenarche may start earlier than previously recognized. Compared to ordinary growth these children seen to use a greater part of their potential for adult height already at that early age.     

Bone density patterns after normal and premature menopause

Objectives: The investigation of the effect of time and type of menopause on bone mineral density (BMD) at different ages. Methods: Five hundred and fourteen women, who had never received any hormonal substitution were studied in a cross-sectional design: 177 with normal (NMP), 210 with surgical (SUMP) and 127 with premature natural (EMP) menopause. Age at menopause was 49.1±3.9, 38.3±4.7 and 38.1±4.2 years (mean±1 S.D.), respectively. BMD was measured at L2–L4 vertebrae and proximal femur by the DEXA method. Results: EMP women presented significantly lower vertebral BMD than NMP women in the 45–55-years segments (P<0.001), but did not differ from SUMP women. This group exhibited lower vertebral BMD than NMP between 45 and 50 years (P<0.001). Regarding femoral neck, EMP women exhibited lower values than SUMP in the 45–50 and 55–65 age segments (P<0.001) whereas SUMP women presented significantly higher BMD values than NMP women after 55 years of age (P<0.001). The percentages of women with vertebral BMD (T-score values) in the osteoporotic range were significantly greater in EMP compared with either NMP or SUMP groups (both P<0.001) whereas in femoral neck lower in SUMP than the other two categories. Conclusions: Women with either natural or surgical premature menopause exhibit lower BMD of trabecular bone compared with normal menopause women at the age segments 45–55 and 45–50, respectively. However, surgical menopause women exceed normal menopause women in their mixed bone BMD values after 60 years as well as premature natural menopause women at almost all age segments.
