Increased risk of stroke in hypertensive women using hormone therapy: analyses based on the Danish Nurse Study.

BACKGROUND: Recent randomized clinical trials suggest an increased risk of stroke with hormone therapy (HT), whereas observational studies have suggested mixed results. Differences in design, definitions of HT exposure, and stroke outcome may explain these discrepancies. Little attention has been paid to identifying subgroups of women who are particularly sensitive to HT. OBJECTIVES: To investigate the risk of various stroke outcomes among women using HT based primarily on estradiol-17beta (unopposed or combined with norethisterone acetate) and to assess the potential modifying effect by presence of risk factors for stroke. DESIGN: Prospective cohort study. SETTING: In 1993, the Danish Nurse Study was established, and questionnaires on lifestyle and HT use were sent to all Danish nurses older than 44 years, of whom 19,898 (85.8%) replied. PARTICIPANTS: Postmenopausal women (n = 13,122) free of previous major cardiovascular and cerebrovascular disease and cancer. MAIN OUTCOME MEASURE: Ischemic or hemorrhagic stroke (n = 144) identified in the national registries of hospital discharges and cause of deaths in the total follow-up through December 31, 1998. RESULTS: In 1993, 28.0% of the 13 122 were current HT users, 14.3% were past users, and 57.7% were never users. Overall, HT exposure was not consistently associated with stroke. However, subdivision based on the presence of hypertension showed a significantly increased risk of stroke among hypertensive women. Compared with hypertensive never HT users, an increased risk of total stroke was found with current use (hazard ratio, 2.35; 95% confidence interval, 1.16-4.74) and especially with current use of estrogen-progestin (hazard ratio, 3.00; 95% confidence interval, 1.33-6.76). Normotensive women had no increased risk of stroke with HT. CONCLUSIONS: We found an increased risk of stroke among hypertensive but not normotensive women using HT. The present study suggests that HT should be avoided in hypertensive women.

Multimodal intervention raises smoking cessation rate during pregnancy.

BACKGROUND: The aim was to study the effect of a multimodal smoking cessation intervention regimen on a number of pregnant smokers. METHODS: A prospective intervention study was designed where participants were allocated to intervention or control based on their birth date. The study included 647 pregnant smokers. The intervention group (n = 327) received initial individual smoking cessation counseling supplemented by an invitation to join, individually or in a group, a smoking cessation program with nicotine replacement therapy as a voluntary option. Intervention was designed as an integral part of the midwives' prenatal care. All pregnant smokers in the usual care group (n = 320) received standard counseling from a midwife. Outcome was self-reported smoking cessation in the 37th week of pregnancy and the reported cessation was validated by cotinine saliva concentration. RESULTS: Self-reported cessation rates during pregnancy were significantly higher in the intervention group (14%) than in the group receiving usual care (5.0%) (p < 0.0001) (Fisher's exact test). Cotinine-validated cessation rates during pregnancy were significantly higher among the former (7%) than the latter (2%) (p = 0.003). The adjusted odds ratio (OR) for smoking cessation was 4.20 (95% CI 2.13-8.03). Logistic regression analysis showed a significant positive association of smoking cessation with low caffeine consumption in pregnancy, many years in school, no exposure to passive smoking outside the home, and previous attempts to stop smoking. CONCLUSIONS: A multimodal intervention regimen with initial individual counseling supplemented by an invitation to join a smoking cessation program with nicotine replacement therapy as a voluntary option markedly increased cessation rates during pregnancy.

Issues to debate on the Women's Health Initiative (WHI) study. Epidemiology or randomized clinical trials--time out for hormone replacement therapy studies?

Over the last 40 years, there has been increasing epidemiological evidence that post-menopausal treatment with sex steroids in physiological doses may reduce the relative risk of cardiovascular disease (CVD). These findings have been supported by biological studies showing favourable changes in cardiovascular risk factors with estrogen supplementation. The impact of the so-called 'healthy user' bias has been eagerly debated, and the results of the first and only randomized long-term clinical trial of HRT for primary prevention have therefore been long awaited. The dramatic decision to halt the Women's Health Initiative (WHI) study before completion came unexpectedly as the consequence of not only an increased risk of breast cancer but also increased occurrence of cardiovascular events with HRT. Due to the superior design of the study, the results from the WHI study have had an enormous impact on the clinical recommendations of HRT to post-menopausal women, concurrent with a degradation of evidence from observational studies. It is not very likely that other long-term randomized clinical trials (RCTs) will be completed and epidemiology has certainly been disreputed-so is this 'time out' for HRT studies?

Hormone replacement therapy and risk of breast cancer: the role of progestins.

Epidemiological studies have shown an increased risk of breast cancer associated with the use of hormone replacement therapy (HRT). This notion is mostly based on studies from the USA. During the last decades unopposed estrogen treatment has been used to a lesser extent, whereas the combined estrogen-progestin treatment regimen is now prescribed worldwide. In the USA the predominant compounds are conjugated estrogens and medroxyprogesterone-acetate, whereas oestradiol combined with testosterone-like progestins is commonly used in Europe. These differences are mainly the result of traditions. Recent studies originating from both the USA and Europe suggest that the combined treatment regimens with estrogen and progestin increase the risk of breast cancer beyond the risk following the use of unopposed estrogen. At present it is not known if progestins with different androgenecity influence the risk of breast cancer to a varying degree. This review focuses on studies published after the latest meta-analysis in 1997, with special attention given to the type of progestin used and the treatment mode, i.e. cyclical or continuous regimen.

Short convalescence after vaginal prolapse surgery.

OBJECTIVE: Retrospectively to describe the recommended convalescence according to patients who had undergone vaginal prolapse surgery in 1996-98, and prospectively to describe the need for and limiting factors for convalescence after vaginal prolapse surgery in 1999-2000 at a Danish University Hospital. METHODS: The retrospective study included a validated, postal, questionnaire and review of patient files. In the prospective study, we followed consecutive women after vaginal surgery in a fast-track setting using a multimodal rehabilitation model with well-defined recommendations for the convalescence period. RESULTS: In the retrospective study, 188 women (79%) with a median age of 66 years (range, 30-88) answered the questionnaire. They had been recommended a convalescence of median 6 weeks (range, 1-12) for most activities. The subjective recurrence rate was 22% within median 6 months (range, 0-24) after first-time prolapse surgery. In the prospective study, there were 41 consecutive women with a median age of 69 years (range, 44-88). Convalescence was median <1 week for most non-strenuous activities, <2 weeks for light work and <4 weeks for sexual intercourse, sports and work with lifts exceeding 10 kg. Limiting factors were fatigue and pain. The 1-year subjective recurrence rate was 17%. CONCLUSION: Traditionally, recommended convalescence has been median 6 weeks after vaginal prolapse surgery. Convalescence has been shortened to 1-3 weeks with a multimodal rehabilitation model with revised, non-restrictive recommendations. Further studies are necessary to evaluate the impact of different convalescence recommendations on the recurrence of prolapse.

Improved fertility following conservative surgical treatment of ectopic pregnancy.

OBJECTIVE: To evaluate fertility after salpingectomy or tubotomy for ectopic pregnancy. DESIGN: Retrospective cohort study. SETTING: Clinical University Center, Hvidovre Hospital, Copenhagen. POPULATION: Two hundred and seventy-six women undergoing salpingectomy or tubotomy for their first ectopic pregnancy between January 1992 and January 1999 and who actively attempted to conceive were followed for a minimum of 18 months. METHODS: Retrospective cohort study combined with questionnaire to compare reproductive outcome following salpingectomy or tubotomy for ectopic pregnancy. Cumulative probabilities of pregnancy for each group were calculated by the Kaplan-Meier estimator and compared by Cox regression analysis to control for potential confounders. MAIN OUTCOME MEASURES: Intrauterine pregnancy rates and recurrence rates of ectopic pregnancy after surgery for ectopic pregnancy. RESULTS: The cumulative intrauterine pregnancy rate was significantly higher after tubotomy (88%) than after salpingectomy (66%) (log rank P < 0.05) after correction for confounding factors. No difference was found in the recurrence rate of ectopic pregnancy between the treatments (16% vs 17%). In patients with contralateral tubal pathology, the chance of pregnancy was poor (hazard ratio 0.463) and the risk of recurrence was high (hazard ratio 2.25), assessed with Cox regression. The rate of persistent ectopic pregnancy was 8%. CONCLUSION: Conservative surgery is superior to radical surgery at preserving fertility. Conservative surgery is not followed by an increased risk of repeat ectopic pregnancy, but by the risk of persistent ectopic pregnancy, which should be taken into account when deciding on the operative procedure. Management in case of contralateral tubal pathology is disputed and should ideally be addressed in a randomised clinical trial.

Fast track vaginal surgery.

OBJECTIVE: Our aim was to describe the need for postoperative hospitalization after vaginal surgery for utero-vaginal prolapse with well-defined charts for postoperative care. DESIGN: A prospective, descriptive study. Consecutive women admitted for first-time vaginal surgery for utero-vaginal prolapse at a public university hospital in Copenhagen, Denmark, underwent surgery and postoperative care in a fast track setting from September 15, 1999 to June 15 2000. METHODS: A multimodal rehabilitation model with emphasis on information, standardized general anesthesia, reduced surgical distress, optimized pain-relief, early oral nutrition and ambulation, minimal use of indwelling catheter and vaginal packing. OUTCOME MEASURES: Postoperative hospital stay, complications, re-admission, success rate, patients' satisfaction and acceptability. RESULTS: Forty-one women with a median age of 69 years (range, 44-88 years) were included. All underwent anterior and/or posterior vaginal repair. Nineteen (46.3%) underwent vaginal hysterectomy, and eight (19.5%) underwent the Manchester procedure. Postoperative hospital stay was median 24 hr. Only three (7.3%) were discharged later than 48 hr. No re-admissions occurred. The most frequent complications were urinary retention exceeding 450 ml, and urinary tract infection (12.2%, and 9.8%, respectively). Short-term success rate was 97.6%. Patients' satisfaction rates were 85.4-95.1%. The median score of acceptability was 10 on a 0-10 points scale. CONCLUSION: The need for postoperative hospitalization was median 24 hr after vaginal surgery in a fast track setting, independently of the complexity of the procedure performed. Short-term success rate, satisfaction rates, and acceptability were all excellent. Follow up has been established to evaluate long-term success rates and recurrence.

Persistent ectopic pregnancy after linear salpingotomy: a non-predictable complication to conservative surgery for tubal gestation.

BACKGROUND: The drawback of conservative surgery for ectopic pregnancy (EP) is the risk of persistent trophoblast. The purpose was to characterize patients who develop persistent ectopic pregnancy (PEP) after salpingotomy for EP and to assess prognostic factors. METHODS: The medical records of 417 patients treated by salpingotomy for EP were reviewed. Forty-eight (11.5%) patients were diagnosed with persistent EP. The data were analyzed using the Mann-Whitney U-test, Fischer's exact test or the chi2-test. RESULTS: Of 417 women, 48 (11,5%) were treated for PEP by either repeat surgery (n = 25) or methotrexate (n = 23). Oral methotrexate failed in 4/19 cases while intramuscular (i.m.) methotrexate was successful in 4/4 cases. Women treated for PEP had a higher preoperative and a slower postoperative decline of serum human chorionic gonadotropin (hCG). Both the preoperative and the early postoperative hCG levels had a low diagnostic sensitivity (0.38-0.66) and specificity (0.74-0.77) for predicting PEP. In multivariate logistic analysis, none of the following clinical variables were predictive of PEP: duration of surgery, laparoscopic approach, history of previous EP, history of previous lower abdominal surgery, ruptured EP, pelvic adhesions, absence of products of conception at microscopy and hemoperitoneum. CONCLUSIONS: Persistent ectopic pregnancy can neither be predicted from clinical variables nor from single measurements of hCG with an accuracy sufficient for clinical use.

Danish gynecologists' opinion about hysterectomy on benign indication: results of a survey.

AIMS: To survey Danish gynecologists' recommendations concerning hysterectomy and its method for benign diseases. METHODS: A questionnaire of seven clinical cases was sent to all gynecologists in Denmark (n = 450). The gynecologists were asked to recommend one of 14 possible treatments as the most appropriate for each case. In cases of hysterectomy the gynecologists were asked to rate the appropriateness of oophorectomy. Questions about age, employment, geographic area, sex of the gynecologist and preference of the hysterectomy method for themselves/their wives were included. RESULTS. THE RESPONSE RATE WAS: 73%. For women aged > or = 50 years meno-metrorrhagia and symptomatic fibroids seemed to be important for hysterectomy recommendations, and for those aged < 50 years asymptomatic fibroids and unexplained pelvic pain seemed important for recommendation of other treatments. Employment, gender and geographic area influenced the recommendation of hysterectomy, and employment and geographic area only for the recommended method. Most of the gynecologists recommended the abdominal route and preferred the subtotal method. The gynecologists agreed on the recommendation concerning oophorectomy in cases of women aged under 46 years and over 55 years. Disagreement was found in cases of perimenopausal women. The gynecologists' preferences for hysterectomy methods did not differ from their recommendations for the cases. CONCLUSIONS: Agreement regarding the recommendation of hysterectomy was found in cases of postmenopausal metrorrhagia, while disagreement was found in cases of asymptomatic leiomyomas and unexplained pelvic pain. The gynecologists preferred the abdominal route and the subtotal hysterectomy method. Certain attributes of the gynecologists were found to be important to the recommendation of hysterectomy and its method.

Hysterectomy in Denmark. An analysis of postoperative hospitalisation, morbidity and readmission.

INTRODUCTION: The aim of this study was to describe the incidence of "standard" hysterectomy in Denmark, including surgical procedure, postoperative hospitalisation, morbidity, mortality and readmission rate within 30 days. MATERIAL AND METHODS: Analysis of data from the Danish National Patient Register for a two-year period (1998-2000) concerning hysterectomies for benign indications, carcinoma in situ cervicis uteri and endometrial carcinoma stage I. A stratified sample of 821 discharge resumés was reviewed for detection of complications. RESULTS: During the two years 10,171 women underwent "standard" hysterectomy followed by a median postoperative hospitalisation of 4 days. In departments performing more than 100 operations per year, the median hospital stay varied from 3 to 5.5 days. Eighty per cent were performed by laparotomy, 6% laparoscopically assisted and 14% by the vaginal route with marked regional variation in the choice of surgical approach. The number of vaginal hysterectomies varied from 0-67% in departments with a surgical activity of more than 100 per year. The mortality rate was 0.06% and 8% were readmitted within 30 days after the operation. If allowing extrapolation from the random sample to the entire population the complication rate was estimated to a minimum of 18%. CONCLUSION: "Standard" hysterectomy in Denmark is associated with considerable morbidity and marked regional variation in choice of surgical approach. The present study emphasizes the need for a national hysterectomy database with the possibility of evaluating surgical activity, reducing morbidity rates and developing homogeneous guidelines.
