Risk of irregular menstrual cycles and low peak bone mass during early adulthood associated with age at menarche.

BACKGROUND: The risk of irregular menstrual cycles and low peak bone mass of the lumbar spine in young adult women, associated with age at menarche, has not been clearly defined. The aim of this study was to investigate this further. METHODS: A total of 180 college females aged 20-23 years were surveyed about menstruation, exercise, and calcium intake by means of a questionnaire. We also measured vertebral bone mineral density in these women by dual energy X-ray absorptiometry. The subjects were divided into six groups according to their age at menarche. Comparisons were made of the mean body mass index (BMI) and T-scores (the ratio to the mean bone mineral density of young adult Japanese women) among those groups, and odds ratios of irregular menstrual cycles and low peak bone mass less than 87% (- 1 standard deviation (SD) of T-scores were calculated using the mean menarcheal age (12 years) group as a control. RESULTS: The mean BMI and T-scores were significantly lower in delayed menarche groups (equal to or more than 13 years) compared with early menarche groups (equal to or less than 12 years). The odds ratios of irregular menstrual cycles were 5.9 (95% confidence intervals (CI) 1.7-20.6), 13.7 (95% CI 3.6-51.6), and 73 (95% CI 6.5-813.9) in the 13-, 14-, and more than 14 years menarcheal age groups, respectively. The odds ratio of low peak bone mass less than 87% (- 1SD) was 3.4 (95% CI 1.1-10.3) in the 14 years menarcheal age group. CONCLUSIONS: Young adult women with delayed menarche may be at high risk for irregular menstrual cycles and low peak bone mass.

Pudendal enterocele with bladder involvement.

A 72-year-old diabetic women presented with a large left labial mass following multiple prior vaginal surgeries to correct vaginal vault prolapse, including two failed right-sided sacrospinalis fixation procedures and a near total colpocleisis. After failure of conservative management, a translabial repair of this pudendal hernia containing bladder was performed. Return of the labial mass 9 months later prompted a more extensive abdominal approach. To close the defect in the urogenital diaphragm and prevent its recurrence, an absorbable mesh was used. Then, to prevent enterocele recurrence, vaginal vault suspension to the sacral promontory and closure of the Douglas pouch were performed. A review of the literature is presented, with an analysis of risk factors and corrective surgical techniques.

Ilioinguinal nerve entrapment during needle suspension for stress incontinence.

The anatomy of the ilioinguinal nerve makes it vulnerable to entrapment near its exit from the superficial inguinal ring, where it lies almost directly superior to the pubic tubercle. During a 27-month period (December 1986 to March 1989), we encountered seven cases of ilioinguinal nerve entrapment following needle suspension procedures. In each case the diagnosis was made because of characteristic pain localized to the medial groin, mons, labia majora, and inner thigh. The intensity and character of the pain varied considerably, presumably depending on the time and degree of nerve compression. This paper discusses the resulting pain complex, diagnosis, pathophysiology, and options for prevention and treatment of this uncommon complication.
