Abstract
INTRODUCTION A key aspect of the public health response to COVID-19 in Scotland was enhanced community surveillance, including testing in dental settings. Across Scotland, dental settings offered patients over 5-years-old the opportunity to participate in community surveillance of COVID-19. METHODS A Health Inequalities Impact Assessment (HIIA) was conducted to understand the differential impacts the programme would have on the population and to improve the accessibility of the programme. HIIA is a tool to allow the assessment, understanding, and mitigation of impacts on people of a proposed policy or practice. It fulfils an organisational duty to meet the requirements of the Equality Act and Fairer Scotland Duty. The HIIA was conducted rapidly in parallel with the programme development. An action research approach included an online workshop, consultation, review of population data and a literature search. RESULTS Adjustments were required to improve the programme's accessibility. Stakeholders, including dental teams from across Scotland were involved in the consultation and brought their front-line experience in different settings. Common issues identified included digital literacy and access, language and cultural barriers to participation, and issues relating to the implications of a positive COVID-19 result. Literature indicated limited evidence on the acceptability, accessibility, and equity of asymptomatic COVID-19 surveillance. CONCLUSION This HIIA was conducted during the COVID-19 pandemic. As an example of good practice in tackling inequalities in access to programmes it should represent the benchmark for other similar initiatives.

Abstract
INTRODUCTION An economic evaluation (EE) was conducted alongside a randomized controlled trial (the Protecting Teeth @ 3 Study [PT@3]), exploring the additional preventive value of fluoride varnish (FV) application at 6-monthly intervals in nursery schools compared to treatment as usual (TAU) in the same nurseries. TAU represented a multicomponent national child oral health improvement intervention, the Childsmile program, apart from nursery FV. METHODS The EE was a within-trial cost-utility analysis (CUA) comparing the FV and TAU groups. The CUA was conducted from a National Health Service perspective and followed relevant methods guidance. Within-trial costs included intervention costs and health care resource use costs. Health outcomes were expressed in quality-adjusted life years (QALYs) accrued over the 2-y follow-up period. The Child Health Utility 9 Dimensions questionnaire was used to obtain utility scores. National reference costs were used, a discount rate of 1.5% for public health interventions was adopted, multiple imputation methods for missing data were employed, sensitivity analyses were conducted, and incremental cost-utility ratios were calculated. RESULTS Data from 534 participants from the 2014-2015 PT@3 intake were used in the EE analyses, n = 265 (50%) in the FV arm and n = 269 (50%) in the TAU arm. Mean incremental cost per child in the FV arm was £68.37 (P = 0.382; 95% confidence interval [CI], -£18.04 to £143.82). Mean incremental QALY was -0.004 (P = 0.636; 95% CI, -0.016 to 0.007). The probability that the FV intervention was cost-effective at the UK £20,000 threshold was 11.3%. CONCLUSION The results indicate that applying FV in nurseries in addition to TAU (all other components of Childsmile, apart from nursery FV) would not be deemed cost-effective given current UK thresholds. In view of previously proven clinical effectiveness and economic worthiness of the universal nursery toothbrushing component of Childsmile, continuation of the additional, targeted nursery FV component in its pre-COVID-19 form should be reviewed given its low probability of cost-effectiveness. KNOWLEDGE TRANSFER STATEMENT The results of this study can be used by child oral health policy makers and dental public health professionals. They can form part of the evidence to inform the Scottish, UK, and international guidance on community-based child oral health promotion programs.

Abstract
Abstract
Background
One-third of the burden of cancer is associated with four health harming behaviours - tobacco use, alcohol consumption, poor diet and physical inactivity. The growing evidence base supporting price-related policies to curb over consumption is of interest to governments globally. However, implementation requires public and policy-maker support. The aim of this study is to enhance our understanding of the features of message framing that influence public support for price-related policies in relation to tobacco, alcohol, and sugar.
Methods
We conducted 18 semi-structured interviews (9 UK and 9 USA) exploring knowledge, attitudes, and beliefs of 4 price policies in relation to tobacco, alcohol and sugar. Interviewees included cancer policy advocates, cancer survivors and members of the public. We used NVivo 12 to organise the data for inductive and deductive thematic analysis.
Results
Common supportive features included: (i) highlighting the health benefit (eg reduced cancer risk), arising from impact on purchasing behaviour; (ii) indirectly making the health harm associated with consumption clear. Common unsupportive features included: (i) policy effectiveness will depend on size of the financial penalty and consumer response; (ii) such policies are unfair on sensible consumers and potentially regressive. Interviewees were more supportive of price-related policies for products containing tobacco where they perceived a stronger association with cancer risk.
Conclusions
This study reveals important differences in levels of persuasiveness arising from the framing of messages to promote price-related policies. The results informed the identification of 4 frames to be tested in a multi-factorial quantitative study, currently under way. These frames can be characterised as: F1 - To reduce the financial strain on healthcare systems; F2 - For the protection of children; F3 - To reduce cancer risk; and F4 - To reduce the risk of other non-communicable diseases.
Key messages
Tailoring the framing of price-related policies in relation to the product they are applied to may increase public acceptability. This may in turn facilitate their implementation.

Abstract
Aims To examine, for the first time on a population-basis via data linkage, whether early detection by general dental practices (GDP) is a realistic expectation by i) estimating the number of OC cases/year a dentist in Scotland may encounter over time, accounting for the deprivation level of practice location and dental registration/attendance rates, and ii) assessing whether patients attended GDPs two years pre-diagnosis. Materials and methods Scottish Cancer Registry data on all OC cases (2010-2012), published NHS Scotland dental workforce and registration/participation statistics, and individual patient data linked with NHS dental service activity were analysed. Results Dentists were estimated to potentially encounter one case of OC every 10 years, OCC every 16.7 years, and OPC every 25 years. However, 53.7% of OC patients had made no dental contact two years pre-diagnosis. Conclusion Strategies for early detection must consider the rarity of OC incidence and poor dental attendance patterns. These results highlight the importance of improving access and uptake of dental services among those at highest risk to increase the opportunities for early detection.

Abstract
OBJECTIVES HPV16-positive oropharyngeal cancer (OPC) patients experience better outcomes compared to HPV16-negative patients. Currently, strategies for treatment de-escalation are based on HPV status, smoking history and disease stage. However, the appropriate cut-point for smoking and the role of other non-clinical factors in OPC survival remains uncertain. MATERIALS AND METHODS We examined factors associated with OPC outcome in 321 patients recruited in a large European multi-center study. Seropositivity for HPV16 E6 was used as a marker of HPV16 positive cancer. Hazard ratios (HR) and confidence intervals (CI) were estimated using Cox proportional models adjusted for potential confounders. RESULTS Overall 5-year survival following OPC diagnosis was 50%. HPV16-positive OPC cases were at significantly lower risk of death (aHR = 0.51, 95% CI: 0.32-0.80). A significant effect on OPC survival was apparent for female sex (aHR 0.50: 95% CI: 0.29-0.85) and being underweight at diagnosis (aHR: 2.41, 95% CI: 1.38-4.21). A 10 pack year smoking history was not associated with overall survival. Higher stage at diagnosis appeared as the only factor significantly associated with OPC recurrence (aHR: 4.88, 95% CI: 2.12-11.21). CONCLUSION This study confirms that HPV16 status is an independent prognostic factor for OPC survival while female sex lowers risk of death and being underweight at diagnosis increases the risk of death. Smoking was not an independent predictor of OPC survival.

Abstract
BACKGROUND AND OBJECTIVES Children in state care ('looked after children') have poorer health than children who are not looked after. Recent developments in Scotland and elsewhere have aimed to improve services and outcomes for looked after children. Routine monitoring of the health outcomes of looked after children compared to those of their non-looked after peers is currently lacking. Developing capacity for comparative monitoring of population-based outcomes based on linkage of routinely collected administrative data has been identified as a priority. To our knowledge there are no existing population-based data linkage studies providing data on the health of looked after and non-looked after children at national level. Smaller scale studies that are available generally provide very limited information on linkage methods and hence do not allow scrutiny of bias that may be introduced through the linkage process. STUDY DESIGN AND METHODS National demonstration project testing the feasibility of linking routinely collected looked after children, education and health data. PARTICIPANTS All children in publicly funded school in Scotland in 2011/12. RESULTS Linkage between looked after children data and the national pupil census classified 10,009 (1.5%) and 1757 (0.3%) of 670,952 children as, respectively, currently and previously looked after. Recording of the unique pupil identifier (Scottish Candidate Number, SCN) on looked after children returns is incomplete, with 66% of looked after records for 2011/12 for children of possible school age containing a valid SCN. This will have resulted in some under-ascertainment of currently and, particularly, previously looked after children within the general pupil population. Further linkage of the pupil census to the National Health Service Scotland master patient index demonstrated that a safe link to the child's unique health service (Community Health Index) number could be obtained for a very high proportion of children in each group (94%, 95% and 95% of children classified as currently, previously, and non-looked after, respectively). In general, linkage rates were higher for older children and those living in more affluent areas. Within the looked after group, linkage rates were highest for children with the fewest placements and for those in permanent fostering. CONCLUSIONS This novel data linkage demonstrates the feasibility of monitoring population-based health outcomes of school-aged looked after and non-looked after children using linked routine administrative data. Improved recording of the unique pupil identifier number on looked after data returns would be beneficial. Extending the range of personal identifiers on looked after children returns would enable linkage to health data for looked after children who are not in publicly funded schooling (i.e. those who are preschool or postschool, home schooled or in independent schooling).

Abstract
Secretion of antimicrobial proteins (AMPs) and salivary antibodies can modify biofilm formation at host body surfaces. In adolescents, associations have been reported between dental caries and salivary AMPs. AMPs demonstrate direct antimicrobial effects at high concentrations, and at lower more physiological concentrations they mediate changes in host cell defenses, which may alter the local environment and indirectly shape local biofilm formation. The expression of salivary AMPs in preschool children, at an age when the oral bacteria are known to change, has not been investigated. We sought to investigate salivary AMP expression in the context of previously well-documented changes in the oral cavities of this age group including salivary immunoglobulin A (IgA), oral bacteria and dental caries. Dental plaque and saliva were collected from 57 children aged 12-24 months at baseline, of whom 23 children were followed-up at 3 years of age. At each time, saliva was assessed for LL37, human neutrophil peptides 1-3, calprotectin, lactoferrin, salivary IgA, total plaque bacteria and Streptococcus mutans. Over time, concentrations of AMPs, S. mutans and bacteria-specific salivary IgA increased. Caries experience was also recorded when children were 3 years old. Concentrations of AMPs were highest in the saliva of 3-year-old children with the greatest burden of S. mutans. These data suggest that salivary AMPs are variable over time and between individuals, and are linked with bacterial colonization. At follow up, the majority of children remained caries free. Larger longitudinal studies are required to confirm whether salivary AMP levels are predictive of caries and whether their modulation offers therapeutic benefit.

Abstract
We aimed to assess the association between the roll-out of the national nursery toothbrushing program and a reduction in dental decay in five-year-old children in a Scotland-wide population study. The intervention was supervised toothbrushing in nurseries and distribution of fluoride toothpaste and toothbrushes for home use, measured as the percentage of nurseries participating in each health service administrative board area. The endpoint was mean d(3)mft in 99,071 five-year-old children, covering 7% to 25% of the relevant population (in various years), who participated in multiple cross-sectional dental epidemiology surveys in 1987 to 2009. The slope of the uptake in toothbrushing was correlated with the slope in the reduction of d(3)mft. The mean d(3)mft in Years -2 to 0 (relative to that in start-up Year 0) was 3.06, reducing to 2.07 in Years 10 to 12 (difference = -0.99; 95% CI -1.08, -0.90; p < 0.001). The uptake of toothbrushing correlated with the decline in d(3)mft (correlation = -0.64; -0.86, -0.16; p = 0.011). The result improved when one outlying Health Board was excluded (correlation = -0.90; -0.97, -0.70; p < 0.0001). An improvement in the dental health of five-year-olds was detected and is associated with the uptake of nursery toothbrushing.

Abstract
BACKGROUND The study aimed to investigate the role of medical history (skin warts, Candida albicans, herpetic lesions, heartburn, regurgitation) and medication use (for heartburn; for regurgitation; aspirin) in the aetiology of upper aerodigestive tract (UADT) cancer. METHODS A multicentre (10 European countries) case-control study [Alcohol-Related CAncers and GEnetic susceptibility (ARCAGE) project]. RESULTS There were 1779 cases of UADT cancer and 1993 controls. History of warts or C. albicans infection was associated with a reduced risk [odds ratio (OR) 0.80, 95% confidence interval (CI) 0.68-0.94 and OR 0.73, 95% CI 0.60-0.89, respectively] but there was no association with herpetic lesions, heartburn, regurgitation or medication for related symptoms. Regurgitation was associated with an increased risk for cancer of the oesophagus (OR 1.47, 95% CI 0.98-2.21). Regular aspirin use was not associated with risk of UADT cancer overall but was associated with a reduced risk for cancer of oesophagus (OR 0.51, 95% CI 0.28-0.96), hypopharynx (OR 0.53, 95% CI 0.28-1.02) and larynx (OR 0.74, 95% CI 0.54-1.01). CONCLUSIONS A history of some infections appears to be a marker for decreased risk of UADT cancer. The role of medical history and medication use varied by UADT subsites with aspirin use associated with a decreased risk of oesophageal cancer and suggestive of a decreased risk of hypopharyngeal and laryngeal cancers.

Abstract
INTRODUCTION In the European Union, there are 180,000 new cases of upper aerodigestive tract (UADT) cancer cases per year--more than half of whom will die of the disease. Socioeconomic inequalities in UADT cancer incidence are recognised across Europe. We aimed to assess the components of socioeconomic risk both independently and through their influence on the known behavioural risk factors of smoking, alcohol consumption and diet. PATIENTS AND METHODS A multicentre case-control study with 2198 cases of UADT cancer and 2141 controls from hospital and population sources was undertaken involving 14 centres from 10 countries. Personal interviews collected information on demographics, lifetime occupation history, smoking, alcohol consumption and diet. Socioeconomic status was measured by education, occupational social class and unemployment. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed using unconditional logistic regression. RESULTS When controlling for age, sex and centre significantly increased risks for UADT cancer were observed for those with low versus high educational attainment OR=1.98 (95% CI 1.67, 2.36). Similarly, for occupational socioeconomic indicators--comparing the lowest versus highest International Socio-Economic Index (ISEI) quartile for the longest occupation gave OR=1.60 (1.28, 2.00); and for unemployment OR=1.64 (1.24, 2.17). Statistical significance remained for low education when adjusting for smoking, alcohol and diet behaviours OR=1.29 (1.06, 1.57) in the multivariate analysis. Inequalities were observed only among men but not among women and were greater among those in the British Isles and Eastern European countries than in Southern and Central/Northern European countries. Associations were broadly consistent for subsite and source of controls (hospital and community). CONCLUSION Socioeconomic inequalities for UADT cancers are only observed among men and are not totally explained by smoking, alcohol drinking and diet.

Abstract
BACKGROUND Oral and oropharyngeal cancers can be managed by surgery alone or with any combination of radiotherapy, chemotherapy and immunotherapy/biotherapy. Opinions on the surgical treatment, the optimal combinational therapy and the sequence of treatments in combinational therapy varies enormously. OBJECTIVES To determine which surgical treatment modalities for oral and oropharyngeal cancers lead to the best outcomes compared with other surgical, radiotherapy, chemotherapy or immunotherapy/biotherapy combinations. SEARCH STRATEGY Electronic search of the Cochrane Oral Health Group Trials Register, CENTRAL, MEDLINE, OLDMEDLINE, EMBASE, AMED and the National Cancer Trials Database. Reference lists from relevant articles were searched and the authors of eligible trials were contacted. Date of the most recent searches: July 2007. SELECTION CRITERIA Randomised controlled trials of surgery alone or in combination with chemotherapy, radiotherapy or immunotherapy/biotherapy for the treatment of primary oral or oropharyngeal cancer or both. DATA COLLECTION AND ANALYSIS A minimum of two review authors conducted data extraction. Risk ratios were calculated for dichotomous outcomes at different time intervals, and hazard ratios were extracted or calculated for disease-free survival, total mortality, and disease-related mortality. Additional information from trial authors was sought. Data on adverse events were collected from the trial reports. MAIN RESULTS Thirty-one trials satisfied the inclusion criteria, only 13 of which were assessed as low risk of bias. Trials were grouped into 12 main comparisons. There were no trials that compared different surgical modalities of the primary tumour itself. However, there were a number of trials comparing different approaches to managing the cervical lymph nodes. The majority of treatment regimens under evaluation were surgery in combination with other modalities. As individual treatment regimens within each comparison varied, meta-analysis was inappropriate in most instances. Only two trials could be pooled, comparing concomitant radio/chemotherapy (with surgery) versus radiotherapy (with surgery). A statistically significant difference was shown for disease-free survival (hazard ratio 0.77, 95% confidence interval (CI): 0.64 to 0.92) and total mortality (hazard ratio 0.78, 95% CI: 0.64 to 0.95) in favour of the concomitant chemotherapy and radiotherapy (with surgery) arm. No other treatment regimens showed consistent statistically significant results across the outcomes measured. AUTHORS' CONCLUSIONS There is some evidence that concomitant radio/chemotherapy (with surgery) is more effective than radiotherapy (with surgery) and may benefit outcomes in patients with more advanced oral and oropharyngeal cancers. As these trials were based on head and neck studies, future studies should evaluate this treatment regimen specifically in oral and oropharyngeal cancers separately and also address tumour staging and its impact on outcomes. In general, future studies are encouraged to evaluate site-specific and stage-specific data for oral and oropharyngeal cancers. Future trials should include health-related quality of life assessment as an outcome measure. There is a need for a consolidated standardised approach to reporting adverse events.

Abstract
OBJECTIVE To examine levels of dental caries of 5-year-olds attending multi-ethnic schools in Greater Glasgow and to explore the effects of deprived backgrounds and ethnic identity on their dental health. DESIGN Between October 2001 and February 2002 a cross-sectional dental epidemiology survey of a sample of 721 5-year-olds was undertaken in schools having at least 25 per cent of pupils from black or minority ethnic groups. Background data on participating children were obtained from school records, including: ethnic origin, mothers' ability to speak English, religion, and demographics. Statistical analyses included two way analysis of variance to determine the effect of ethnicity after adjusting for socio-economic factors. RESULTS Complete data were available for 649 (90%) children. The sample broadly divided into white (52%), Pakistani (33%), and other minority ethnic groups (15%). Based on repeat observations, diagnosis reliability was good (Kappa = 0.77). The caries experience of Pakistani children (d3mft = 4.1; 95% CI 3.6 to 4.6) was significantly higher (p < 0.001) than the white children (d3mft = 2.3; 95% CI 1.9 to 2.6). Only 25% (95% C1 17 to 34) of the Pakistani children had no obvious decay, significantly lower (p < 0.001) than their white contemporaries (48%, 95% CI 39 to 58). Pakistani ethnic origin was associated with significantly higher levels of dental caries (p < 0.001), after adjusting for socio-economic deprivation. CONCLUSION Children from deprived backgrounds have worse dental caries levels than their affluent counterparts and, over and above this effect, minority ethnic children of Pakistani background have higher levels than their white peers.

Abstract
AIM In 2003, the West of Scotland Cancer Awareness Programme (WoSCAP) launched their oral cancer campaign to raise public awareness of the disease in five NHS boards across the West of Scotland. The aim of this study was to evaluate the campaign by reviewing patients attending rapid access clinics in the 11 secondary care units across the five boards. DESIGN Data were collected in 2004 during the second phase of the campaign via a two part self-completing questionnaire; the first part collected information from the patients and the second part from the clinicians, in rapid access clinics in the secondary care units. RESULTS In total, 580 questionnaires were given out in the clinics with 538 completed patient sections (response rate 93%) and 500 completed clinician sections (response rate of 86%). More than two thirds of rapid access secondary care patients had seen a recent health campaign related to mouth cancer, and 46% responded that the campaign had encouraged them to seek advice more quickly. Of the patients examined in the clinics, 5% had a provisional diagnosis of a malignant lesion, 7% a potentially malignant lesion, and the majority of lesions were benign. The clinicians deemed 30% of the referrals to be inappropriate. CONCLUSIONS The results show a high percentage of patients attending rapid access clinics were aware of the campaign. However, there were a disproportionate number of inappropriate referrals to the rapid access clinics compared to genuinely urgent cases.

Abstract
This study aimed to determine whether the incidence of oral cancer is continuing to rise in the UK and if this varies geographically. A descriptive epidemiological study of oral cancer incidence in 12 UK cancer registries (1990-1999) was undertaken. Poisson regression models were employed to assess trends. There were 32,852 oral cancer cases registered (1990-1999). Statistically significant increases in incidence of 18% and 30% were seen in males and females respectively (p<0.01). The trend was observed in younger (<45 years) and older (45+ years) age groups (p<0.01) with 3.5% and 2.4% average annual increases respectively. These increases were consistent for the majority of regions in the older group. For the younger group the increases in incidence were more rapid and differed geographically. Incidence remains higher in men than women, in older compared with younger groups, and in northern regions. These findings provide evidence of a continuing increase in the burden of oral cancer across the UK.

Abstract
OBJECTIVE To compare a conservative and an active policy (immediate oxytocin infusion) of management of prelabour rupture of the membranes in term primigravidae. DESIGN Randomized trial involving 444 women. SETTING District maternity hospital. MAIN OUTCOME MEASURES Caesarean section rate in each group; also the rate of forceps deliveries, spontaneous deliveries, length of labour, number of vaginal examinations, type of analgesia, pyrexia in labour or the puerperium and antibiotic use in the mother and the infant in each group. The caesarean section rate for the whole trial where the latent period was greater than 12 h was compared to that where the latent period was less than or equal to 12 h. RESULTS There were fewer caesarean sections in the conservative group (odds ratio (OR) 0.60, 95% confidence interval (CI) 0.35 to 1.02; P = 0.06). There was a similar number of forceps deliveries (OR 0.79; 95% CI 0.52 to 1.19; P = 0.26) but more spontaneous deliveries (OR 1.57; 95% CI 1.08 to 2.29; P = 0.02) in the conservative group. More women managed conservatively required inhalational analgesia only for pain relief in labour (OR 2.88; 95% CI 1.46 to 5.68; P = 0.003), a similar number required pethidine (OR 1.29; 95% CI 0.85 to 1.94; P = 0.23), and fewer required epidural analgesia (OR 0.57; 95% CI 0.39 to 0.84; P = 0.005). The number of vaginal examinations was less in the conservative group (difference between mean 0.53; 95% CI 0.25 to 0.80; P less than 0.001). Fewer women managed conservatively experienced four or more vaginal examinations in labour (OR 0.58; 95% CI 0.39 to 0.86; P = 0.007). There were no differences in the lengths of labour, the proportions of women who developed pyrexia in labour or the puerperium or who required antibiotics or in the proportions of infants who required antibiotics. CONCLUSIONS These results argue in favour of a conservative policy in managing primigravidae at term with prelabour rupture of the membranes.

Abstract
Specialist infertility practice was studied in a group of 708 couples within a population of residents of a single health district in England. They represented an annual incidence of 1.2 couples for every 1000 of the population. At least one in six couples needed specialist help at some time in their lives because of an average of infertility of 21/2 years, 71% of whom were trying for their first baby. Those attending gynaecology clinics made up 10% of new and 22% of all attendances. Failure of ovulation (amenorrhoea or oligomenorrhoea) occurred in 21% of cases and was successfully treated (two year conception rates of 96% and 78%). Tubal damage (14%) had a poor outlook (19%) despite surgery. Endometriosis accounted for infertility in 6%, although seldom because of tubal damage, cervical mucus defects or dysfunction in 3%, and coital failure in up to 6%. Sperm defects or dysfunction were the commonest defined cause of infertility (24%) and led to a poor chance of pregnancy (0-27%) without donor insemination. Obstructive azoospermia or primary spermatogenic failure was uncommon (2%) and hormonal causes of male infertility rare. Infertility was unexplained in 28% and the chance of pregnancy (overall 72%) was mainly determined by duration of infertility. In vitro fertilisation could benefit 80% of cases of tubal damage and 25% of unexplained infertility--that is, 18% of all cases, representing up to 216 new cases each year per million of the total population.

Abstract
In a population and family study we have examined the relationship between HLA types, classical congenital adrenal hyperplasia (CAH), and variants of 21 hydroxylase (21 OH) deficiency detected by increased blood levels of 17 hydroxyprogesterone (17 PO) in response to ACTH after overnight suppression with dexamethasone ('short Synacthen test'). In a non-CAH population, 7.7% of subjects were found to have raised 17 PO response suggesting reduced activity of 21 OH. Such subjects with raised 17 PO levels were designated simply as type 2 responders because the relationship with genotype was unknown. Post-ACTH levels of 17 PO were significantly greater in type 2 responders than in obligate carriers of CAH. A total of 2.5% of the population studied also had raised progesterone (PO) levels in the Synacthen test. HLA-A28 and B14 (in linkage disequilibrium) were significantly increased in frequency and HLA-B12 decreased in the type 2 responders. HLA-Bw47, which is known to be associated with CAH, was found only among obligate carriers of classical CAH. Because type 2 response and classical CAH are linked to HLA but are associated with different antigens, it is likely that they are determined by two (or more) alleles.

Abstract
The feasibility of studying ovarian arterial blood flow has been demonstrated, using an ultrasonic method combining real-time imaging and pulsed Doppler (the 'duplex' method). Results using a percutaneous full-bladder technique were validated by comparison with use of an ultrasound probe applied directly to the arteries at laparotomy. The ovarian arteries demonstrated qualitatively and quantitatively distinct flow patterns compared with the internal and external iliac arteries. From recorded waveforms a pulsatility index (PI) reflecting vascular impedance was calculated. The PI was found to be lower, indicating increased blood flow, in the artery supplying the ovary carrying the dominant follicle or corpus luteum. Serial studies suggest that this change occurs at an early stage of the menstrual cycle, possibly before the dominant follicle can be recognized by its size or increased hormone production. Uterine arterial flow was also detectable, more accurately abdominally than vaginally, and the changes typical of late pregnancy were already found to be present, though to a lesser degree, in the first trimester.

Abstract
One hundred and thirty-five healthy primigravid women at or near term with spontaneous rupture of the membranes without uterine contractions were submitted to a prospective trial of management. Rupture of the membranes was diagnosed by speculum examination. If labor did not commence, induction was performed by oxytocin infusion starting at 9 AM following admission. One hundred and five women went into labor spontaneously before induction became necessary. Sixty-three of these women required augmentation with oxytocin. Twenty-seven percent of the induced group required cesarean section delivery compared to 10% of those in spontaneous labor augmented by oxytocin and to none of those who did not require oxytocin (p less than 0.01). Ninety-four percent of those in spontaneous labor were delivered vaginally compared to 73% of the induced group (p less than 0.01). Forty-one percent of the augmented group were delivered by forceps. Awaiting the spontaneous onset of labor for 24 hours or less did not result in clinical maternal or neonatal infection. We would therefore advocate awaiting the spontaneous onset of labor after spontaneous rupture of membranes without contractions at or near term in healthy primigravid women for up to 24 hours because it seems to confer significant advantages without producing any additional hazard.

Abstract
Adrenal steroidogenesis has been studied in vivo in eleven patients aged 13-68 years with 21-hydroxylase deficiency, in one patient with 11 beta-hydroxylase deficiency and in ten female control subjects. Serum levels of the delta 5 3 beta-hydroxysteroids, pregnenolone (Pe), 17 alpha-hydroxypregnenolone (17Pe), dehydroepiandrosterone (DHEA) and androstenediol (Adiol) and their delta 4 3-keto counterparts, progesterone (Po), 17 alpha-hydroxyprogesterone (17Po) androstenedione (Adione) and testosterone as well as of 11-deoxycortisol and cortisol were measured during acute adrenal suppression with dexamethasone followed by stimulation with synthetic 1-24 ACTH. In the seven patients with 21-hydroxylase deficiency who were on adequate glucocorticoid therapy, grossly exaggerated responses of 17Po and Po to ACTH were nevertheless preserved. In contrast, there was a grossly subnormal response of 17Pe, DHEA and Adiol to ACTH, and low basal levels of DHEA-sulphate. In the untreated patients the response of 17Pe and DHEA was normal. The Adione response was exaggerated in untreated and normal in treated cases. Similar findings obtained in the patient with 11 beta-hydroxylase deficiency who was studied after 6 weeks without replacement therapy. Our findings demonstrate that production of adrenal steroids that are associated with the adrenarche is not exaggerated in untreated CAH, and is grossly suppressed in treated cases. These findings are compatible with the hypothesis that intra-adrenal cortisol may initiate and/or maintain production of the delta 5 steroids by the zona reticularis that occurs in the human adrenarche.

Abstract
The total serum bilirubin levels at two and occasionally five days after birth were studied in 162 infants whose mothers received either intravenous oxytocin or oral Prostaglandin te2 during labour, and the results were compared with those obtained in forty-two control patients. Following labour of spontaneous onset, whether the mother received intravenous oxytocin or oral Prostaglandin E2, neonatal total serum bilirubin levels were not different from those in controls. After induction by amniotomy and an active agent, higher mean total serum bilirubin levels were found in infants whose mothers received intravenous oxytocin than in those given oral prostaglandin E2; a significant rise in the total serum bilirubin level appeared to occur when mothers received a total of more than 12,000 milliunits of oxytocin or more than 4,000 milliunits per kg birthweight of the infant.
