Authors: Bererhi Haddia , Kolhoff Niels , Constable Anthony , Nielsen Stig Pors 
Published: August 2005

Objective
To investigate the influence of multiparity on bone mass of the axial skeleton in a population of women of high parity.Design
Open study of Omani women.Setting
Medical physics department and clinical physiology department of a third degree referral (university) hospital.Participants
A consecutive series of 159 normal women referred with low back pain over a period of six months.Results
The bone mineral density was measured with dual‐photon absorptiometry and the mean was found to be 0.984 (± 0.166) (± SD) g cm−2. The age ranged from 20 to 70 years with a mean age of 43.4 (± 12.5) years. The number of children per woman ranged from 0 to 14 with a mean of 5.1 (53.5). There was no statistically significant influence of the number of children per woman on bone mineral density but there was a strong correlation with age and body size variables.Conclusion
Multiparity does not influence lumbar spine bone mineral density in normal women.

Authors: Tingulstad Solveig , Hagen Bjørn , Skjeldestad Finn Egil , Onsrud Mathias , Kiserud Torvid , Halvorsen Tore , Nustad Kjell 
Published: August 2005

Objective
To evaluate the ability of a risk of malignancy index (RMI), based on a serum CA125 level, ultrasound findings and menopausal status, to discriminate a benign from a malignant pelvic mass and to discriminate early stage (Figo Stage I) from Stages II, III and IV of ovarian cancer.Design
A prospective study.Setting
Department of Gynaecology, Trondheim University Hospital, Trondheim, Norway.Participants
One hundred and seventy‐three women, 30 years or older, consecutively admitted between February 1992 and February 1994 for primary laparotomy of a pelvic mass.Main outcome measures
The sensitivity, specificity and positive predictive value of serum CA125 level, ultrasound findings and menopausal status, separately and combined into the RMI, to diagnose ovarian cancer.Results
The RMI was more accurate than any individual criterion in diagnosing cancer. Using a RMI cut‐off level of 200 to indicate malignancy, the RMI derived from this dataset gave a sensitivity of 80%, specificity of 92% and positive predictive value of 83%. Applying RMI criteria developed by others, the following test performance was found: sensitivity 71%, specificity 96% and positive predictive value 89%. For the Stages II, III and IV of ovarian cancer the sensitivity increased to approximately 90% without any substantial loss in specificity.Conclusions
The risk of malignancy index is able to correctly discriminate between malignant and benign pelvic masses. It is a scoring system which can be introduced easily into clinical practice to facilitate the selection of patients for primary surgery at an oncological unit.
Fetal karyotyping in twin pregnancies: selection of technique by measurement of fetal nuchal translucency
Authors: Sebire N. J. , Noble P. L. , Psarra A. , Papapanagiotou G. , Nicolaides K. H. 
Published: August 2005

Objective
To examine the usefulness of selecting the appropriate techque for fetal karyotyping in twin pregnancies by using maternal age and fetal nuchal translucency thickness to determine risk for chromosomal defects in each fetus.Setting
Fetal Medicine Centre, London, United Kingdom.Subjects
Sixty‐seven twin pregnancies identified at the time of an ultrasound scan for determination of fetal nuchal translucency thickness, where the parents requested karyotyping.Intervention
The risk for chromosomal defects in each fetus was calculated from the maternal age and fetal nuchal translucency thickness at 10 to 14 weeks of gestation. If the estimated risk for either fetus was 1 in 50 or greater, chorion villus sampling was the method of choice, whereas if the risk was less than 1 in 50 second trimester amniocentesis was performed.Results
The estimated risk for trisomies was more than 1 in 50 in 34 pregnancies and 23.5% of these fetuses were found to be chromosomally abnormal. In contrast, in the 33 low risk pregnancies chromosomal abnormalities were found in only 1.5% of the fetuses.Conclusions
In twin pregnancies the technique for fetal karyotyping may be selected by calculating the risk for chromosomal abnormality based on maternal age and fetal nuchal translucency thickness.

Authors: Lim F. T. H. , Holm J. P. , Schuitemaker N. W. E. , Jansen F. H. M. , Hermans J. 
Published: August 2005

Objective
To compare a one‐step (rapid) application of negative pressure (vacuum) with conventional stepwise application for ventouse extraction following a prolonged second stage of labour.Design
Randomised controlled study.Setting
Teaching Hospital.Participants
Forty‐seven women were randomised to the rapid vacuum group and 47 to the stepwise group.Main outcome measures
Duration of ventouse procedure, effectiveness of methods of application, morbidity of mother and infant.Results
There was no significant difference in frequency of detachment of the cup after rapid or stepwise application of vacuum. A reduction in mean duration of the ventouse procedure of 6 min was realised without significant difference in maternal or neonatal morbidity.Conclusion
Rapid application of vacuum significantly reduces the duration of a ventouse extraction procedure without compromise to efficiency and safety.
Are sociodemographic factors predictive of preterm birth? A reappraisal of the 1958 British Perinatal Mortality Survey
Authors: Wildschut Hajo I. J. , Nas T. , Golding J. 
Published: August 2005

Objective
Reassessment of the predictive value of sociodemographic factors on preterm birth.Design
Population‐based case—control study.Setting
England, Wales and Scotland.Sample
The study sample consisted of 5630 primiparous and 9538 multiparous women who were delivered during the first week of March 1958 in Britain. Multiple births were excluded.Method
Factors potentially predictive of preterm birth were assessed for primiparous and multiparous women separately, using the split‐sample cross‐validation technique.Main outcome measure
Preterm birth, defined as birth occurring before 259 days of gestation.Results
Preterm birth rates for primiparous and multiparous women were 54 and 53 per 1000 births, respectively. In primiparous women low maternal age (under 20 years) was the only sociodemographic variable that was predictive of preterm birth (P= 0.01). However, only 10.7% of preterm birth among primiparous women was associated with low maternal age. In multiparous women, using univariable analysis, employment status was statistically significantly associated with preterm birth. This association disappeared when employment status was adjusted for by other variables in the model. Social class was not predictive of preterm birth in either primiparous or multiparous women.Conclusion
From the results of this study it is concluded that sociodemographic factors do not have a substantial impact on the risk of preterm birth. It seems unlikely that preventative measures aimed at social‐demographic adversity will reduce preterm birth rates.

Authors: Zethraeus Niklas , Johannesson Magnus , Henriksson Peter , Strand Roland T. 
Published: August 2005

Objective
To measure the gain in quality of life due to hormone replacement therapy for women with mild and severe menopausal symptoms.Design
Prospective study where data on quality of life and willingness to pay were collected by interview.Setting
Department of Gynaecology at Sodertalje Hospital near Stockholm.Participants
One hundred and four women aged 45 to 65 years treated for menopausal symptoms for at least one month.Methods
Quality oflife was measured by the time tradeoff and rating scale methods. The willingness to pay for hormone replacement therapy was investigated using the contingent valuation method.Main outcome measures
The quality adjusted life year weight measured with the rating scale and time tradeoff methods, and willingness to pay.Results
The increase in the quality adjusted life year weight due to hormone replacement therapy for women with mild symptoms was 0.26 according to the rating scale method and 0.18 according to the time tradeoff method. For women with severe symptoms the quality adjusted life year weight increased by 0.50 according to the rating scale method and by 0.42 according to the time tradeoff method. The mean willingness to pay for hormone replacement therapy per month was 2300 Swedish krone for women with mild symptoms and 4800 Swedish krone for women with severe symptoms (£1 = 10.3 Swedish krone).Conclusions
Hormone replacement therapy leads to a major improvement in quality of life for women with menopausal symptoms. Both for women with mild and severe menopausal symptoms the willingness to pay for the treatment also greatly exceeds the costs, indicating that hormone replacement therapy is economically beneficial for women with menopausal symptoms.

Authors: Kieler Helle , Haglund Bengt , Waldenström Urban , Axelsson Ove 
Published: August 2005

Objective
To test a hypothesis of no association between ultrasound exposure in early fetal life and growth or impaired vision or hearing during childhood.Design
Follow up of eight to nine year old children born to women who participated in a randomised controlled trial on ultrasound screening during pregnancy.Setting
Nineteen antenatal care clinics run by three central hospitals in Sweden from 1985 to 1987.Population and methods
Of 4637 eligible singleton pregnancies, 3265 (71%) were followed up through a questionnaire sent to their mothers. Analyses were performed both according to randomised groups and to ultrasound exposure.Main outcome measures
Parents’ report of vision and hearing tests as recorded on child's record card. Parents’ report of their child's weight and height at 1, 4 and 7 years of age.Results
Reduced hearing was reported by 3.4% in the screening group compared with 3.5% in the nonscreening group (odds ratio [OR] 1.0; 95% confidence interval [CI] 0.67–1.41). The same prevalences were found when analysed according to ultrasound exposure (OR 1.0; 95% CI 0.67–1.42). Reduced vision was reported by 6.3% in the screening group compared with 7.8% in the nonscreening group (OR 0.8; 95% CI 0.60–1.03). Corresponding figures for ultrasound exposed and unexposed were 6.2% and 8.0%, respectively (OR 0.8; 95% CI 0.58–1.00). No statistically significant differences in body weight or height at 1, 4 or 7 years of age between screened and not screened children or between exposed and unexposed were found.Conclusion
This study found no association between ultrasound exposure in early fetal life and growth or impaired vision or hearing during childhood.

Authors: Cooper Kevin G. , Parkin David E. , Garratt Andrew M. , Grant Adrian M. 
Published: August 2005

Objectives To compare medical with hysteroscopic management in women referred to a gynaecologist complaining of heavy menstrual loss.Design Single‐centre randomised trial.Setting A teaching hospital in the United Kingdom.Participants One hundred and ninety‐seven women seeking specialist treatment of heavy menstrual loss for the first time and willing to accept either treatment.Interventions 1. Medical treatments not previously used by the women prescribed by experienced gynaecologists in standard doses and timings for a minimum of three cycles (n= 94), and 2. transcervical resection of the endometrium performed under general anaesthesia five weeks after goserelin preparation (n= 93).Main outcome measures Treatment satisfaction and acceptability, relief of symptoms, change in haemoglobin, and improvement in health related quality of life, all after four months.Results Women allocated transcervical resection were more likely to be totally or generally satisfied (76%versus 27%, P < 0.001), to find the treatment acceptable (93%versus 36%, P < 0.001), and willing to have the treatment again (93%versus 31%, P < 0.001). Although pain and bleeding were significantly reduced by medical treatment this was modest in comparison with transcervical resection (P < 0.001). Haemoglobin levels were significantly increased only following transcervical resection. Short form 36 scores were also improved in both arms, although only transcervical resection returned them to normal values.Conclusions Medical treatment was less effective than transcervical resection of the endometrium, irrespective of previous treatment or type of medical management. Early hysteroscopic endometrial surgery should be considered by such woman with the choice made by the woman after a full discussion of the advantages and disadvantages of all the options.
A new questionnaire to assess the quality of life of urinary incontinent women
Authors: Kelleher C. J. , Cardozo L. D. , Khullar V. , Salvatore S. 
Published: August 2005

Objectives To design and validate a condition‐specific quality of life questionnaire for the assessment of women with urinary incontinence, and to use the questionnaire to assess the quality of life of women with specific urodynamic diagnoses.Setting A tertiary referral Urogynaecology unit at King's College Hospital, LondonDesign The questionnaire was designed following six different pilot studies; in this study it was tested for validity and reliability using standard psychometric techniques. The questionnaire was used in 293 consecutive women referred for investigation of urinary incontinence.Results The questionnaire was shown to be reliable both by test‐retest analysis and by measurement of its internal consistency. The construct of the questionnaire and the answers by respondents confirmed its face and content validity. Criterion validity was measured by correlation with scores obtained on a validated generic measure of quality of life, the Short Form 36. Women with detrusor instability had greater quality of life impairment than women with other urodynamic diagnoses.Conclusion The questionnaire was easy for the women to use and was a valid and reliable instrument for the assessment of quality of life in women with urinary incontinence. It will be useful for the rapid appraisal and follow up of women with urinary incontinence in many different clinical settings, including the evaluation of new treatments of urinary incontinence in controlled clinical trials.

Objective
1. To audit the management of cervical carcinoma in the South West Region with the aim of identifying and addressing deficiencies. 2. To determine whether recent NHS restructuring has affected the provision of cancer care.Design
Retrospective review of hospital case notes.Setting
All hospitals in the South West Region of England.Population
Three hundred and twenty‐four women with a diagnosis of cervical carcinoma: 191 were diagnosed in 1989 and 133 in 1993.Main outcome measures
Documentation of patient assessment and management.Results
There was a mean delay of 17 days (range 0–66) from cervical smear to cytology report and 34 days (range 1–380) from general practitioner referral to attendance at a hospital clinic. Overall, 175 women (54%) had evidence of cytological assessment prior to treatment and 137 (42%) had a colpo‐scopic assessment; 49% had cytological assessment and 37% had colposcopy in 1989, compared with 60% and 50%, respectively, in 1993. Excluding 49 cases of micro‐invasive carcinoma, 238 case notes (86%) contained evidence of clinical examination; 195 women (71%) had had an examination under anaesthesia, 115 (42%) a chest radiograph, 123 (45%) an intravenous urogram or renal ultrasound, and 92 (33%) cystoscopy. One hundred and forty‐seven women (53%) had FIGO staging recorded in the notes. As first line treatment, 69 had conservative surgery (39 for Stage IA), 138 had radiotherapy, and 107 had radical surgery. Ten had radical surgery for Stage IA but eight had a > 3 mm invasion or lymphatic/vascular spread. Thirty‐one had Stage IB treated with radiotherapy of whom 14 were younger than 50 years of age. Following radical surgery 30% had evidence of sampling 10 nodes, and 9% had tumour extending to the resection margins.Conclusions
Record keeping was inadequate but appeared to indicate inconsistent cytological, clinical, colposcopic and radiological assessment, leading to inappropriate clinical delays and conservative surgery. Radical surgery often appeared inadequate, but poor node sampling rates may also reflect insufficient histopathological preparation or reporting. There was a reduction in the number of new cases of cervical carcinoma diagnosed in 1993, perhaps reflecting an observed increase in cytological surveillance. No other alterations in clinical practice were observed over the four‐year period. We feel it is imperative to standardise assessment throughout the region with a minimum clinical and histopathological dataset.

Objective
To examine options of management and outcome of twin pregnancies discordant for anencephaly.Design
Retrospective study.Setting
Research Centre for Fetal Medicine.Population
Twenty‐four twin pregnancies discordant for anencephaly.Methods
A computer search was made of our database for twin pregnancies discordant for anencephaly. The data were reviewed for gestation at presentation, chorionicity, management and pregnancy outcome.Main outcome measures
Pregnancy outcome in relation to chorionicity and management.Results
There were 13 dichorionic and 11 monochorionic twin pregnancies discordant for anencephaly. In the dichorionic group five pregnancies had selective fetocide at 17 to 21 weeks; one pregnancy resulted in spontaneous abortion but in the others a healthy infant was born at a median gestation of 37 weeks. The other eight dichorionic pregnancies were managed expectantly, but three developed polyhydramios at 26 to 30 weeks; in one case amniodrainage was performed and in another selective fetocide was carried out. In this group the median gestation at delivery was 35 weeks. All 11 monochorionic pregnancies were managed expectantly and in three there was intrauterine death of both fetuses. In the other eight cases the normal twin was liveborn at a median gestation of 34 weeks; in four of these pregnancies polyhydramnios developed and two were managed by amniodrainage.Conclusions
In monochorionic pregnancies, expectant management is associated with a high rate of intrauterine lethality of the normal twin. In dichorionic pregnancies selective fetocide in the second trimester prevents the development of polyhydramnios and is associated with a lower risk of preterm delivery but can cause miscarriage.
Liver function tests in pre‐eclampsia: importance of comparison with a reference range derived for normal pregnancy
Authors: Girling J. C. , Dow E. , Smith J. H. 
Published: August 2005

Objectives
To determine reference ranges for liver function tests in uncomplicated pregnancy and to relate abnormal results by these criteria to outcome in pre‐eclampsia.Design
Prospective, cross‐sectional study to establish the reference ranges. Prospective observational study of women with pre‐eclampsia.Setting
Antenatal clinics and obstetric unit of St Mary's Hospital, London.Participants
Four hundred and thirty women with uncomplicated pregnancies and 85 consecutive women with gestational hypertension.Main outcome measures
Aspartate transaminase (AST), alanine transaminase (ALT), bilirubin and gamma glutamyl transferase (GGT) were measured to determine their ranges in normal pregnancy. The severity of pre‐eclampsia was determined by the maximum blood pressure, creatinine and 24 h urinary protein; minimum platelet count; maternal complications; mode of and gestation at delivery; and fetal outcome with centile weight adjusted for gestational age and sex.Results
AST, ALT, bilirubin and GGT were each lower in uncomplicated pregnancy than the nonpregnant laboratory reference ranges. Of those cases with elevated liver function tests in the pre‐eclampsia group, 37% were abnormal only by the new reference ranges. Using the new ranges, the prevalence of elevated liver function tests was significantly higher in the pre‐eclampsia group (54%) than in those with pregnancy induced hypertension (14%) (P < 0.01). Amongst those with pre‐eclampsia, abnormal liver function tests were associated with greater proteinuria(P < 0.05), lower platelet count(P < 0.001) and more maternal complications(P < 0.01) than normal liver function tests; there was no difference in the severity of hypertension between the groups.Conclusions
Liver function tests are lower in normal pregnancy than the reference ranges currently used. Our pregnancy‐derived ranges allow more precise identification of abnormal liver function in women with pre‐eclampsia than is possible using standard reference ranges derived from a nonpregnant population.

Objective
To determine the normal vulvar findings by naked eye examination and by vulvoscopy in healthy women without vulvar complaints.Design
Observational study.Population
Forty healthy volunteers without vulvar complaints recruited via a newspaper advertisement.Methods
Vulvar examination, human papillomavirus (HPV) polymerase chain reaction of vulvar and cervical swabs, saline and KOH smears and vulvoscopy before and after the application of 5% acetic acid.Main outcome measures
Prevalence of vestibular erythema, vestibular papillomatosis, HPV infection on the vulva and in the cervix and vulvoscopic findings.Results
The mean age of the women was 37.8 years (median 38.0, range 21–56). Nine women were current smokers and 21 had previously smoked. Naked eye vulvar examination showed vestibular papillomatosis in 13 women (33%) and vestibular erythema in 17 women (43%). The touch test was positive in 9 of the 17 women (53%) with vestibular erythema. Vulvoscopy after the application of acetic acid 5% showed an acetowhite vestibule in all women. Twelve women (30%) had acetowhite lesions outside the vestibule. Six women (15%) were positive for HPV DNA. The presence of HPV DNA did not correlate with vestibular erythema or vestibular papillomatosis. There was a weak association between HPV DNA and acetowhite lesions outside the vestibule (P= 0.055, Fisher's exact test). In this group the younger women significantly more often had vestibular papillomatosis (t‐statistic = 3.07; P= 0.003) and women who smoke more often had a genital HPV infection (P= 0.016, Fisher's exact test).Conclusions
Vestibular erythema, vestibular papillomatosis, and acetowhite lesions are common in this group of healthy women without vulvar complaints.
