Pilot study: quality of life assessment of postnatal fatigue and other physical morbidity

Postnatal morbidity is increasingly recognized, but standard assessments may not capture what is most important to the woman with such morbidity in terms of her quality of life. The Mother-Generated Index (MGI) is a proposed postnatal quality-of-life instrument which allows the mother to determine both content and scoring. In this pilot study we found that although a degree of psychological and physical morbidity (including tiredness) is common, and may be very significant, for most women these factors are low-grade, and other aspects of their lives are more important. A quality-of-life approach allows the mother to determine her own postnatal assessment, and encourages practitioners to view her more holistically.     

Borderline hyperprolactinemia in infertile women: evaluation of the prolactin response to thyrotropin releasing hormone and double-blind placebo-controlled treatment with bromocriptine

Twenty-two women with on average more than 3 years unexplained infertility including normal menstrual cycles were studied because of borderline hyperprolactinemia (repeated serum prolactin concentrations 400-1000 mU/l). Randomized double-blind treatment with bromocriptine 5 mg daily (leading to adequate prolactin suppression) or matching placebo, each for 4 cycles, resulted in a cumulative rate after 4 months of 14.3 +/- 10.6% (SE) in both groups. Also, the results of treatment were not significantly related to the serum prolactin response to an intravenous injection of thyrotropin releasing hormone, whether the response was blunted (ratio of peak to basal prolactin within 60 minutes of injection no greater than 2), intermediate (greater than 2 to 4) or normal (greater than 4).     

Sexual function, delivery mode history, pelvic floor muscle exercises and incontinence: a cross-sectional study six years post-partum

Background: There is controversy over the effect of mode of delivery, pelvic floor muscle exercises (PFME), incontinence and sexual function.
Aim: To investigate the relationship of sexual function with delivery mode history, PFMEs and incontinence.
Methods: This was a cross-sectional postal survey of women, six years post-partum, who had given birth in maternity units in Aberdeen, Birmingham and Dunedin and had answered a previous questionnaire. Each sexual function question was analysed separately by anova .
Results: At six years post-index delivery, 4214 women responded, of whom 2765 (65%) answered the optional ten sexual function questions. Although there was little association between delivery mode history and most sexual function questions, women who had delivered exclusively by caesarean section scored significantly better on the questions relating to their perception of vaginal tone for their own ( P -value < 0.0001) and partner's ( P -value 0.002) sexual satisfaction, especially when compared with women who had had vaginal and instrumental deliveries. Women who reported that they were currently performing PFME scored significantly better on seven questions. Women with urinary or faecal incontinence scored significantly poorer on all sexual function questions.
Conclusions: Mode of delivery history appeared to have minimal effect on sexual function. Current PFME performance was positively associated with most aspects of sexual function, however, all aspects were negatively associated with urinary and faecal incontinence.     

Hypoxemia after general anesthesia in children

Postoperative hypoxemia has been well documented in adults but not in infants and children, although they are potentially more susceptible to airway closure and to disturbances in pulmonary gas exchange. In a prospective study, we measured arterial oxygen saturation (SaO2) with a pulse oximeter in 97 ASA class I infants and children breathing room air before and after general anesthesia for superficial surgical procedures. Mean preoperative SaO2 was 97.6 +/- 0.15% (SEM). On arrival in the recovery room after anesthesia mean SaO2 in room air had decreased significantly (P less than 0.01) to 93.0 +/- 0.49% (range 100-71%), corresponding to calculated arterial oxygen tension (PaO2) of about 66 mm Hg. The second reading, 5-15 min later, also showed a statistically significant (P less than 0.01) decrease in SaO2 (94.1 +/- 0.35%). There was no statistical difference in SaO2 between patients who received inhalation anesthesia alone and those who were given narcotics. There was also no correlation between postoperative reduction in SaO2 and duration of anesthesia or patient age. Of 67 patients who were asleep on arrival in the recovery room, 47 who remained asleep at the second SaO2 reading had an average increase in SaO2 of less than 1%. In contrast, in those patients who awoke, average SaO2 increased more than 4% during a similar time period--a difference that was statistically significant (P less than 0.02).     

Treating nocturnal enuresis in children: review of evidence.

BACKGROUND: Childhood nocturnal enuresis (bedwetting) affects many families. Although it has a high rate of spontaneous remission, bedwetting may bring social and emotional stigma, stress, and inconvenience to both the child with enuresis and his or her family. DESIGN: Summary of systematic reviews of treatment for nocturnal enuresis in children, published in the Cochrane Library, using evidence only from randomized and quasi-randomized trials to compare interventions. Interventions included behavioral, alarm, and pharmacologic treatments. SETTING AND METHODS: Six Cochrane Reviews contributed evidence to this review: simple behavioral interventions, alarms, complex behavioral or educational interventions, desmopressin, tricyclics and related drugs, and other drugs. SUBJECTS: The participants were children (usually up to the age of 16). RESULTS: Much of the available evidence was of poor quality, and there were few direct comparisons between different types of intervention. Simple behavioral Interventions, such as reward systems, are widely used as standard first-line treatment, but they require a high level of parental involvement. There is currently little evidence to show that these interventions work, but they may be worth trying because they have only a few adverse effects. The use of an alarm intervention reduced nighttime bed wetting in a majority of children both during and after treatment. Overlearning or dry-bed training may reduce the relapse rate. Before embarking on alarm treatment, families need to be made aware of both the time and the high level of parental involvement necessary to attain success. Drug therapy, such as desmopressin and tricyclics, reduced the number of wet nights per week compared with placebo but only while the drug was used. Patients and their families need to be warned about possible side effects of some of the drugs. CONCLUSIONS: Alarms are the most effective treatment for nocturnal enuresis in children, but desmopressin may be considered for temporary relief.     

Cost effectiveness of tension-free vaginal tape for the surgical management of female stress incontinence

OBJECTIVES: Stress urinary incontinence affects between 10 percent and 50 percent of women. Surgery is commonly recommended for troublesome incontinence that does not respond to nonsurgical management. Tension-free vaginal tape (TVT) is a newer, minimal access surgical sling procedure, which is being increasingly adopted worldwide. The cost-effectiveness of TVT in comparison with other surgical procedures, particularly open colposuspension, is assessed. METHODS: Effectiveness estimates came from a systematic review of TVT compared with other surgical procedures (open and laparoscopic colposuspension, traditional slings, and injectables). Deterministic and probabilistic analyses were used to assess the likelihood of TVT being cost-effective. Sensitivity analyses assessed the impact of changing assumptions about cure rates and costs for TVT, cure rates for retreatment open colposuspension, and proportions of women who choose retreatment. RESULTS: Reliable estimates of relative effectiveness were difficult to derive because the few randomized controlled comparisons had not been optimally analyzed or fully reported. Results of the economic model suggested that TVT dominates open colposuspension (lower cost and same quality of life years [QALYs]) within 5 years after surgery. Stochastic analysis indicated that the likelihood of TVT being cost-effective was 100 percent if decision-makers are unwilling to pay for additional QALYs. TVT's dominance depended on the assumption fact that retreatment open colposuspension has lower cure rates than a first colposuspension. CONCLUSIONS: Analysis based on current short-term data indicates dominance of TVT over open colposuspension from approximately 5 years. There is a need for longer-term follow-up data from methodologically rigorous randomized trials to provide a sounder basis for estimating the relative benefits and cost implications.     

The prognostic power of the post-coital test for natural conception depends on duration of infertility

Controversy about the value of the post-coital test (PCT) has prompted us to re-analyse data from 207 couples, originally studied between 1982 and 1983, with at least 12 months' infertility at presentation, complete diagnostic information and exclusion of female factors, to clarify the effect of duration of infertility on the prediction of conception. In couples with less than 3 years infertility and a positive PCT, 68% conceived within 2 years compared with 17% of those with a negative result. After 3 years, corresponding rates were 14% and 11%. The relative risks of conception [95% confidence interval (CI)] calculated using the Cox's proportional hazards model were 0.23 (0.12-0.43) for a negative PCT (reference positive PCT) and 0.25 (0.13-0.51) for more than 36 months infertility (reference 12-23 months). Semen analysis had no extra predictive power given the duration of infertility and the PCT. The PCT is an effective predictor of conception where defined female causes of infertility are absent and duration of infertility is less than 3 years. Once infertility is prolonged (beyond 3 years) the conception rate is low even with a positive test because a large proportion of couples remaining childless so long have true unexplained infertility. Use of the PCT will enable clinicians to allocate scarce, expensive and invasive resources effectively.     

A two-centred pragmatic randomised controlled trial of two interventions of postnatal support

Objectives To establish whether providing additional postnatal support during the early postnatal months influences women's physical and psychological health and to identify health service benefits.
Design Pragmatic randomised controlled trial with a  2 × 2  factorial design with two interventions.
Setting Community centres, Ayrshire and Grampian, Scotland.
Population One thousand and four primiparous women, 83% completed the baseline questionnaire, 71% at six months.
Methods (1) An invitation to a local postnatal support group run weekly with a facilitator, starting two weeks postpartum. (2) A postnatal support manual, posted two weeks postpartum.
Main outcome measures Data regarding primary outcome postnatal depression (Edinburgh Postnatal Depression Scale, EPDS), secondary outcomes, general health measures (SF-36), social support (SSQ6), use of health services and women's views of interventions were collected at two weeks postpartum and at three and six months.
Results There were no significant differences in EPDS scores between the control and trial arms at three and six months, nor were there differences in the SF-36 and the SSQ6 scores. The 95% CI for the difference in EPDS effectively excluded a change in mean score of more than 10% with either intervention. There were no differences in health service attendances in primary or secondary care between the control and trial arms. Of those women who attended the groups, 40% attended six or more. Women reported favourably on the 'pack' with the majority reading it a few times and feeling that it was aimed at them.
Conclusions Wide-scale provision by the National Health Service of either support groups or self-help manuals is not appropriate if the aim is to improve measurable health outcomes.
