Type 1 von Willebrand disease (vWD) is generally regarded clinically as 'mild' and the obstetrical-gynaecological features have not been fully described. We administered a patient questionnaire and provider survey of the medical and quality of life aspects of childbirth and menstruation to 99 type 1 vWD patients and compared the patients presently menstruating (n=81) to a cohort of 150 menstruating females in the general population. The following measurements had a statistically higher proportion in the vWD group: number of tampons/towels used for a typical menstrual cycle (P=0. 002); percentage reporting that clothes are stained by menses (P = 0. 001); past or present history of anaemia (P = 0.001); childbirth-related bleeding (P=0.001); and childbirth-related bleeding necessitating RBC transfusion (P=0.002). Quality of life assessment of the impact of menses in both of the above cohorts was measured by a Likert scale using seven quality of life parameters. Compared to the control group, the vWD patients had a significantly higher score, with P-values of < 0.0001 for each parameter. Hormonal interventions for menorrhagia in the vWD patients were < or = 50% effective. Menorrhagia resulted in red blood cell transfusions in 6% of patients, dilatation and curettage in 17% and hysterectomy in 13%. Despite the common connotation of type 1 vWD as clinically 'mild', childbirth and the monthly challenge to haemostasis presented by menstruation result in a substantial degree of morbidity in females with type 1 vWD. These results support the rationale for ongoing international efforts to increase awareness of vWD as a cause for menorrhagia and to improve the quality of life in females with known vWD.

There was no advantage to cupfeeding for providing supplements to the general population of healthy breastfed infants, but it may have benefitted mother-infant dyads who required multiple supplements or were delivered by cesarean. Pacifier use in the neonatal period was detrimental to exclusive and overall breastfeeding. These findings support recommendations to avoid exposing breastfed infants to artificial nipples in the neonatal period.

Chronic pelvic pain is a common and significant disorder of women. It is estimated to have a prevalence of 3.8% in women. Often the etiology of chronic pelvic pain is not clear, as there are many disorders of the reproductive tract, gastrointestinal system, urological organs, musculoskeletal system, and psychoneurological system that may be associated with chronic pelvic pain. The history and physical examination are crucial in evaluating a woman with chronic pelvic pain and must address all of the possible systems potentially involved in chronic pelvic pain, not just the reproductive system. Laboratory and imaging studies should be selectively utilized, as should laparoscopy. Conscious laparoscopic pain mapping has been proposed as a way to improve information derived from laparoscopic evaluations. Treatment of chronic pelvic pain may consist of two approaches. One is to treat chronic pain itself as a diagnosis, and the other is to treat diseases or disorders that might be a cause of or a contributor to chronic pelvic pain. These two approaches are not mutually exclusive, and in many patients effective therapy is best achieved by using both approaches. Treatment of chronic pain as well as treatment of four of the more common disorders associated with chronic pelvic pain (endometriosis, adhesions, irritable bowel syndrome, and interstitial cystitis) are discussed in this review.

ABSTRACT. Objective. To evaluate the effects of pacifier use and the timing of pacifier introduction on breastfeeding duration, problems, and frequency.Methods. A cohort of 265 breastfeeding mother-infant dyads was followed prospectively. Maternal interviews were conducted at delivery, 2, 6, 12, and 24 weeks, and thereafter every 90 days until breastfeeding ended. Information was obtained regarding pacifier use, infant feeding, use of supplemental foods and breastfeeding frequency, duration, and problems. The effect of pacifier introduction by 6 weeks of age on breastfeeding duration was evaluated with Kaplan-Meier and Cox proportional hazards models. The effect of the timing of pacifier introduction (<2 weeks and <6 weeks) on breastfeeding duration at 2 and 3 months was evaluated using logistic regression modeling.Results. A total of 181 mothers (68%) introduced a pacifier before 6 weeks. In adjusted analyses, pacifier introduction by 6 weeks was associated with a significantly increased risk for shortened duration of full (hazard ratio, 1.53; 95% confidence interval: 1.15, 2.05) and overall (hazard ratio, 1.61; 95% confidence interval: 1.19,2.19) breastfeeding. Women who introduced pacifiers tended to breastfeed their infants fewer times per day, with significant differences noted at 2 (8.1 ؎ 2.6 vs 9.0 ؎ 2.3) and 12 weeks' (6.3 ؎ 2.0 vs 7.4 ؎ 1.6) postpartum. At 12 weeks postpartum, women who introduced pacifiers also were more likely to report that breastfeeding was inconvenient and that they had insufficient milk supplies. Pacifier use begun either before 2 weeks or before 6 weeks' postpartum was not significantly associated with breastfeeding duration at 2 and 3 months.Conclusions. Pacifier use was independently associated with significant declines in the duration of full and overall breastfeeding. Breastfeeding duration in the first 3 months' postpartum, however, was unaffected by pacifier use. Women who introduced pacifiers tended to breastfeed their infants less frequently and experienced breastfeeding problems consistent with infrequent feeding. Findings from this study suggest that the decreases in breastfeeding duration associated with pacifier use may be a consequence of less frequent breastfeeding among women who introduce pacifiers to their infants.
