Mortality in women given diethylstilbestrol during pregnancy.

We used Cox regression analyses to assess mortality outcomes in a combined cohort of 7675 women who received diethylstilbestrol (DES) through clinical trial participation or prenatal care. In the combined cohort, the RR for DES in relation to all-cause mortality was 1.06 (95% CI = 0.98-1.16), and 1.11 (95% CI = 1.02-1.21) after adjusting for covariates and omitting breast cancer deaths. The RR was 1.07 (95% CI = 0.94-1.23) for overall cancer mortality, and remained similar after adjusting for covariates and omitting breast cancer deaths. The RR was 1.27 (95% CI = 0.96-1.69) for DES and breast cancer, and 1.38 (95% CI=1.03-1.85) after covariate adjustment. The RR was 1.82 in trial participants and 1.12 in the prenatal care cohort, but the DES-cohort interaction was not significant (P = 0.15). Diethylstilbestrol did not increase mortality from gynaecologic cancers. In summary, diethylstilbestrol was associated with a slight but significant increase in all-cause mortality, but was not significantly associated with overall cancer or gynaecological cancer mortality. The association with breast cancer mortality was more evident in trial participants, who received high DES doses.

Lifetime socioeconomic position in relation to onset of perimenopause.

STUDY OBJECTIVE: To assess the association between lifetime socioeconomic position and onset of perimenopause. DESIGN: Prospective cohort study. SETTING: Boston, Massachusetts. PARTICIPANTS: 603 premenopausal women aged 36-45 years at baseline who completed a cross sectional survey on childhood and adult socioeconomic position. MAIN OUTCOME MEASURES: Time to perimenopause, defined as time in months from baseline interview to a woman's report of (1) an absolute change of at least seven days in menstrual cycle length from baseline or subjective report of menstrual irregularity; (2) a change in menstrual flow amount or duration; or (3) cessation of periods for at least three months, whichever came first. MAIN RESULTS: Incidence of perimenopause was 1.75 times higher (95%CI 1.10 to 2.79) and median age at onset was 1.2 years younger (44.7 v 45.9 years) for women reporting childhood and adult economic distress compared with women reporting no lifetime economic distress. After adjustment for age, race/ethnicity, age at menarche, parity, oral contraceptive use, family history of early menopause, depression, smoking, and body mass index, the association weakened (incidence rate ratio (IRR)=1.59; 95%CI 0.97 to 2.61). Inverse associations were observed for most, but not all, measures of educational level. Measures of current household income were not associated with risk of perimenopause. CONCLUSIONS: This study suggests that adverse socioeconomic conditions across the lifespan, when measured in terms of economic hardship and low educational attainment, may be associated with an increased rate of entry into perimenopause.

Adult onset of major depressive disorder in relation to early life violent victimisation: a case-control study.

BACKGROUND: Major depressive disorder is a significant cause of morbidity among women in the USA. Women are twice as likely as men to be diagnosed with major depressive disorder, yet no known risk factors can account for this sex difference. We aimed to assess violent victimisation as a risk factor for depression in women. METHODS: We undertook a case-control study to assess the association between violent victimisation early in life and major depressive disorder in women. We randomly selected a population-based sample of women, aged 36-45 years, from the greater Boston area. In 1999, 236 cases and 496 controls (n=732) completed a self-administered questionnaire designed to ascertain a lifetime history of exposure to violent victimisation. Our main outcome measure was major depressive disorder, assessed by structured clinical interview for Diagnostic Statistical Manual IV (DSM-IV) criteria. FINDINGS: 363 (50%) of 732 respondents reported experience or fear of abuse as a child or adolescent. 68 were excluded because they reported violence as an adult only. Compared with women who reported no abuse, risk of depression was increased in women who reported any abuse as a child or adolescent (relative risk 2.5, 95% CI 1.9-3.0), physical abuse only (2.4, 1.8-3.0), sexual abuse only (1.8, 1.2-2.8), and both physical and sexual abuse (3.3, 2.5-4.1). Severity of abuse had a linear dose-response relation with depression. INTERPRETATION: Our results suggest a positive association between violent victimisation early in life and major depressive disorder in women.

Uterine leiomyomas and their effect on in vitro fertilization outcome: a retrospective study.

PURPOSE: The effect of uterine leiomyomas on the outcome of in vitro fertilization (IVF) treatment has been controversial. This study was undertaken to clarify influence of fibroids on IVF success, in a large population with age and other potential confounding variables controlled for in the analysis. METHODS: A population of 141 patients with and 406 without leiomyomata undergoing their first IVF cycle was studied. RESULTS: The association between uterine leiomyomas and assisted reproduction treatment outcome was not statistically significant (OR = 0.73, 95% CI: 0.49-1.19, p = 0.21) after controlling for age and other risk factors. Also, fibroids neither affected the risk of spontaneous abortion (OR = 1.06, 95% CI: 0.44-2.60) nor the risk of ectopic pregnancy (OR = 0.78, 95% CI: 0.08-8.02). Location of fibroids (intramural vs. submucosal/subserosal) and their size had no significant effect on pregnancy outcome. CONCLUSIONS: Results from our analyses indicated that in vitro fertilization outcome was not affected by the presence of uterine leiomyomas. Therefore, in patients with normal uterine cavities and fibroids less than a certain size (i.e., < 7 cm), undergoing myomectomies as a prerequisite for assisted reproduction treatment is seriously questionable.

Prevalence and predictors of chronic lower genital tract discomfort.

OBJECTIVE: We sought to determine the prevalence of chronic lower genital tract discomfort in the general population and to identify demographic and reproductive characteristics associated with this disorder. STUDY DESIGN: We surveyed a random sample of 480 women (age range, 20 to 59 years; 60 women for each 5-year age category) from 1 Boston area suburban community. Participants were asked to complete a 1-page self-administered optically scannable questionnaire that pertained to current and previous genital tract discomfort. RESULTS: After 2 mailings and 1 telephone follow-up, as well as the elimination of 42 ineligible women, 303 (70%) questionnaires were returned. Fifty-six women (18.5%) reported a history of lower genital tract discomfort that persisted for >3 months. Approximately 12% reported a history of chronic knife-like or excessive pain on contact to the genital area, whereas 6.6% experienced persistent lower genital tract itching or burning. Women who reported their age at menarche to be <or=11 years old were more than twice as likely to report a history of chronic lower genital tract discomfort compared with women who began menses at age 12 or later (odds ratio, 2.4; 95% confidence interval, 1.1 to 4.8). Reported pain at the time of first use of tampons was associated with an increased risk of chronic lower genital tract discomfort later in life (odds ratio, 2.4; 95% confidence interval, 1.1 to 4.9). CONCLUSIONS: We have shown that women from the general population are willing to provide sensitive information on lower genital tract discomfort-a first step toward bringing notice to this understudied disorder. In addition, our data support the theory that vulvar trauma in early life may influence or serve as a marker for risk of subsequent chronic vulvar disorders.

The epidemiology of recurrent pregnancy loss.

In reviewing the epidemiology of recurrent abortion (RAB), we believe it is necessary to consider the epidemiology of spontaneous abortion (SAB) as well, since it is clear that even a single pregnancy loss increases the risk for a subsequent abortion. In addition, any attempt to identify epidemiologic risk factors for SAB or RAB must deal with the fact that at least 50% of SABs are associated with genetic abnormalities. Given that most epidemiologic studies have not distinguished karyotypically abnormal abortuses, risk factors are likely to be underestimated. Nevertheless, there is fair agreement that a variety of factors may increase risk for SAB or RAB, including advanced maternal age, single gene mutations such as PKU or G6PD deficiency, structural abnormalities of the uterus, poorly controlled diabetes, antiphospholipid syndrome, and smoking. More controversial is the role of luteal phase defect or hyperandrogenism, alloimmune factors, genital infections, caffeine or alcohol use, and trace element or chemical exposure from tap water or in the workplace. Besides better designed epidemiologic studies to detect modifiable risk factors for SAB or RAB, there is a clear need for clinical trials of therapy for RAB which meet minimum epidemiologic standards including randomization, double-blinded (when possible), and placebo-controlled (when ethical).

Stapled typhlectomy via colotomy for treatment of cecal inversion in a dog.

A 13-year-old Weimaraner was examined because of chronic diarrhea, hematochezia, and moderate weight loss. Cecal inversion was diagnosed by use of colonoscopy. Exploratory surgery was performed, and the inverted cecum was exteriorized through a colotomy. Typhlectomy was performed by use of a stapling instrument that formed a full-thickness division of the cecum with a double row of staples on each side. This stapling technique provides a rapid, reliable method for treatment of cecal inversion when the cecum cannot be reduced manually.

The accuracy of self and informant ratings of physical functional capacity in the elderly.

To compare the accuracy of self-ratings with informant-ratings of physical functional capacity in the elderly, 150 elderly patients attending a geriatric day hospital (GDH) and their formal and informal community carers were administered a questionnaire about their ability to perform activities of daily living (ADL). Direct observation of the patients' performance by therapists at the GDH was used as a standard, after the reliability and validity of this approach had been evaluated. Self-ratings were shown to be more accurate and less biased than informant-ratings, both for individual ADL and overall functional capacity. The accuracy of all ratings tended to be greater for less complex or physically demanding ADL, and informants tended to consistently underestimate functional capacity. The concurrent validity of the adapted Barthel Index in a self-report format was also demonstrated. Wherever possible, information concerning the physical functional capacity of an elderly subject should in the first instance be sought from the subject himself, as the quality of such information may be superior to that of his carers.

A syndrome resembling feline dysautonomia (Key-Gaskell syndrome) in a dog.

Dysautonomia, or autonomic nervous system dysfunction, was diagnosed in a 1-year-old dog. Clinical signs of disease included diarrhea, vomiting, prolapse of nictitating membranes, and urinary incontinence. Bilateral keratoconjunctivitis sicca, xerostomia, and decreased anal sphincter tone were also observed. On the basis of response to atropine, results of intradermal histamine testing and gastric motility studies, and ocular response to parasympathomimetics and sympathomimetics (direct and indirect acting), autonomic nervous system function was determined to be abnormal. Treatment with metoclopramide hydrochloride and bethanechol chloride resulted in improved attitude, appetite, Schirmer tear test response, and decrease in frequency of vomiting within 24 hours. Bladder function and anal tone improved within 3 weeks.

Social skills training for young adolescents.

A systematic assertiveness training program was developed for adolescents, based on Albert Bandura's social cognitive theory. The program, which focused on peer interactions and social responsibility, consisted of six 40-minute semi-weekly sessions and was presented to a class of 22 sixth-grade social studies students in a middle school. Cognitive acquisition of the information was measured with multiple-choice tests administered immediately after training and at a 6-month follow-up. Trained students performed significantly better than a control group on the posttest (p less than .01) and on the 6-month follow-up (p less than .02), demonstrating that young adolescents can acquire and retain the symbolic information that forms a basis for assertive behavior.

Comparison of renal biopsy techniques in dogs.

To evaluate adequacy of biopsy specimens obtained and safety to the patient, the standard keyhole biopsy technique (using digital immobilization of the right kidney and placement of the biopsy needle up to the capsule before obtaining a tissue sample) was compared with 9 technical modifications. Adequacy was judged by the number of intact glomeruli observed in the specimen. Detection of transected blood vessels and renal pelvis was presumed to have predictive value for postbiopsy complications of hemorrhage and hydronephrosis. Needle biopsy specimens were also obtained from left and right kidneys by use of laparoscopic visualization and were compared with those obtained by use of the standard keyhole technique. Although the standard keyhole technique yielded the highest percentage of adequate biopsy specimens, there was no statistical difference between specimens obtained by this technique and those obtained by the modified technique or by laparoscope-guided biopsy. Also, significant difference in percentage of biopsy specimens with renal pelvis was not found between specimens obtained by the standard and modified techniques. For each technique, the biopsy core length was measured and the mean value was calculated. In this study, core length did not correlate with adequacy of the biopsy specimen.
