Abstract
The aim of our retrospective study is to report on our experience using the Prevena™ wound system in obese patients undergoing caesarean section delivery. A total of 26 cases were identified from July 2012 to October 2013. The median BMI of these women was 45.3 kg/m(2). Elective caesarean sections were performed in 20 women (77%). There were four cases (15%) of superficial dehiscence. Factors associated with wound breakdown were wound infection (p = 0.03), increasing BMI (p < 0.001) and emergency LSCS (p = 0.04). In a logistic regression model the presence of infection was the only factor which remained associated with wound breakdown. Wound disruption is a major cause of morbidity following caesarean section in morbidly obese patients. The wound complication rate in our experience was low with the Prevena™ dressing with no cases of sheath dehiscence, and no patient required a second operation. The presence of infection is the most important factor in wound breakdown and should be the focus for management protocols.

Abstract
INTRODUCTION Helicobacter pylori eradication rates using conventional triple therapies are falling, making viable second-line and rescue regimens necessary. Levofloxacin, tetracycline and rifabutin are three efficacious antibiotics for rescue therapy. AIM We aimed to assess the resistance rates for H. pylori against these antibiotics in an Irish cohort. METHODS Gastric biopsies were collected from 85 patients infected with H. pylori (mean age 46 years) in the Adelaide and Meath Hospital, Dublin in 2008 and 2009. Susceptibility to antibiotics was tested using the Etest. Clinical information was obtained from endoscopy reports and chart review. RESULTS 50.6 % of patients were females. Mean age was 47 years. Ten had prior attempts at eradication therapy with amoxicillin-clarithromycin-PPI, two had levofloxacin-based second-line therapy. 11.7 % [95 % CI (6.5-20.3 %)] (N = 10) had strains resistant to levofloxacin. There were no strains resistant to rifabutin or tetracycline. Levofloxacin resistance in the under 45 age group was 2.6 % (1/38) compared to 19.1 % (9/47) of above 45 age group (p = 0.02). DISCUSSION The levofloxacin rates illustrated in this study are relatively low by European standards and in line with other studies from the United Kingdom and Germany, with younger patients having very low levels of resistance. Levofloxacin, tetracycline and rifabutin are all valid options for H. pylori eradication in Irish patients but the importance of compliance cannot be underestimated.

Abstract
A growing number of studies suggest a potential link between obesity and altered iron metabolism. The purpose of this systematic review was to examine existing literature on iron status in obese populations. A comprehensive literature search was conducted. Included studies recruited participants ≥ 18 years with a body mass index ≥ 30 kg m(-2) and provided descriptive statistics for haemoglobin or ferritin at a minimum. There were 25 studies meeting all eligibility criteria, of these 10 examined iron status in free-living obese individuals and 15 reported baseline iron biomarkers from bariatric surgery candidates. Non-obese comparison groups were used by 10 (40%) articles. In these, seven obese groups reported higher mean haemoglobin concentration; six reported significantly higher ferritin concentration; and four significantly lower transferrin saturation. Due to insufficient data, it was not possible to make conclusions regarding mean differences for soluble transferrin receptor (sTfR), hepcidin or C-reactive protein. Existing evidence suggests a tendency for higher haemoglobin and ferritin concentration and lower transferrin saturation in obesity. Alternation of iron biomarkers in obese populations may be a result of obesity-related inflammation and/or related comorbidities. Further research incorporating measurement of inflammatory cytokines, sTfR and hepcidin is required to confirm the impact of obesity on iron status.

Abstract
OBJECTIVE The aim of this project was to determine the clinical effectiveness and cost-effectiveness of hysterectomy, first- and second-generation endometrial ablation (EA), and Mirena® (Bayer Healthcare Pharmaceuticals, Pittsburgh, PA, USA) for the treatment of heavy menstrual bleeding. DESIGN Individual patient data (IPD) meta-analysis of existing randomised controlled trials to determine the short- to medium-term effects of hysterectomy, EA and Mirena. A population-based retrospective cohort study based on record linkage to investigate the long-term effects of ablative techniques and hysterectomy in terms of failure rates and complications. Cost-effectiveness analysis of hysterectomy versus first- and second-generation ablative techniques and Mirena. SETTING Data from women treated for heavy menstrual bleeding were obtained from national and international trials. Scottish national data were obtained from the Scottish Information Services Division. PARTICIPANTS Women who were undergoing treatment for heavy menstrual bleeding were included. INTERVENTIONS Hysterectomy, first- and second-generation EA, and Mirena. MAIN OUTCOME MEASURES Satisfaction, recurrence of symptoms, further surgery and costs. RESULTS Data from randomised trials indicated that at 12 months more women were dissatisfied with first-generation EA than hysterectomy [odds ratio (OR): 2.46, 95% confidence interval (CI) 1.54 to 3.93; p = 0.0002), but hospital stay [WMD (weighted mean difference) 3.0 days, 95% CI 2.9 to 3.1 days; p < 0.00001] and time to resumption of normal activities (WMD 5.2 days, 95% CI 4.7 to 5.7 days; p < 0.00001) were longer for hysterectomy. Unsatisfactory outcomes associated with first- and second-generation techniques were comparable [12.2% (123/1006) vs 10.6% (110/1034); OR 1.20, 95% CI 0.88 to 1.62; p = 0.2). Rates of dissatisfaction with Mirena and second-generation EA were similar [18.1% (17/94) vs 22.5% (23/102); OR 0.76, 95% CI 0.38 to 1.53; p = 0.4]. Indirect estimates suggested that hysterectomy was also preferable to second-generation EA (OR 2.32, 95% CI 1.27 to 4.24; p = 0.006) in terms of patient dissatisfaction. The evidence to suggest that hysterectomy is preferable to Mirena was weaker (OR 2.22, 95% CI 0.94 to 5.29; p = 0.07). In women treated by EA or hysterectomy and followed up for a median [interquartile range (IQR)] duration of 6.2 (2.7-10.8) and 11.6 (7.9-14.8) years, respectively, 962/11,299 (8.5%) women originally treated by EA underwent further gynaecological surgery. While the risk of adnexal surgery was similar in both groups [adjusted hazards ratio 0.80 (95% CI 0.56 to 1.15)], women who had undergone ablation were less likely to need pelvic floor repair [adjusted hazards ratio 0.62 (95% CI 0.50 to 0.77)] and tension-free vaginal tape surgery for stress urinary incontinence [adjusted hazards ratio 0.55 (95% CI 0.41 to 0.74)]. Abdominal hysterectomy led to a lower chance of pelvic floor repair surgery [hazards ratio 0.54 (95% CI 0.45 to 0.64)] than vaginal hysterectomy. The incidence of endometrial cancer following EA was 0.02%. Hysterectomy was the most cost-effective treatment. It dominated first-generation EA and, although more expensive, produced more quality-adjusted life-years (QALYs) than second-generation EA and Mirena. The incremental cost-effectiveness ratios for hysterectomy compared with Mirena and hysterectomy compared with second-generation ablation were £1440 per additional QALY and £970 per additional QALY, respectively. CONCLUSIONS Despite longer hospital stay and time to resumption of normal activities, more women were satisfied after hysterectomy than after EA. The few data available suggest that Mirena is potentially cheaper and more effective than first-generation ablation techniques, with rates of satisfaction that are similar to second-generation techniques. Owing to a paucity of trials, there is limited evidence to suggest that hysterectomy is preferable to Mirena. The risk of pelvic floor surgery is higher in women treated by hysterectomy than by ablation. Although the most cost-effective strategy, hysterectomy may not be considered an initial option owing to its invasive nature and higher risk of complications. Future research should focus on evaluation of the clinical effectivesness and cost-effectiveness of the best second-generation EA technique under local anaesthetic versus Mirena and types of hysterectomy such as laparoscopic supracervical hysterectomy versus conventional hysterectomy and second-generation EA.

Abstract
OBJECTIVE To evaluate the relative effectiveness of hysterectomy, endometrial destruction (both "first generation" hysteroscopic and "second generation" non-hysteroscopic techniques), and the levonorgestrel releasing intrauterine system (Mirena) in the treatment of heavy menstrual bleeding. DESIGN Meta-analysis of data from individual patients, with direct and indirect comparisons made on the primary outcome measure of patients' dissatisfaction. DATA SOURCES Data were sought from the 30 randomised controlled trials identified after a comprehensive search of the Cochrane Library, Medline, Embase, and CINAHL databases, reference lists, and contact with experts. Raw data were available from 2814 women randomised into 17 trials (seven trials including 1359 women for first v second generation endometrial destruction; six trials including 1042 women for hysterectomy v first generation endometrial destruction; one trial including 236 women for hysterectomy v Mirena; three trials including 177 women for second generation endometrial destruction v Mirena). Eligibility criteria for selecting studies Randomised controlled trials comparing hysterectomy, first and second generation endometrial destruction, and Mirena for women with heavy menstrual bleeding unresponsive to other medical treatment. RESULTS At around 12 months, more women were dissatisfied with outcome with first generation hysteroscopic techniques than with hysterectomy (13% v 5%; odds ratio 2.46, 95% confidence interval 1.54 to 3.9, P<0.001), but hospital stay (weighted mean difference 3.0 days, 2.9 to 3.1 days, P<0.001) and time to resumption of normal activities (5.2 days, 4.7 to 5.7 days, P<0.001) were longer for hysterectomy. Unsatisfactory outcomes were comparable with first and second generation techniques (odds ratio 1.2, 0.9 to 1.6, P=0.2), although second generation techniques were quicker (weighted mean difference 14.5 minutes, 13.7 to 15.3 minutes, P<0.001) and women recovered sooner (0.48 days, 0.20 to 0.75 days, P<0.001), with fewer procedural complications. Indirect comparison suggested more unsatisfactory outcomes with second generation techniques than with hysterectomy (11% v 5%; odds ratio 2.3, 1.3 to 4.2, P=0.006). Similar estimates were seen when Mirena was indirectly compared with hysterectomy (17% v 5%; odds ratio 2.2, 0.9 to 5.3, P=0.07), although this comparison lacked power because of the limited amount of data available for analysis. CONCLUSIONS More women are dissatisfied after endometrial destruction than after hysterectomy. Dissatisfaction rates are low after all treatments, and hysterectomy is associated with increased length of stay in hospital and a longer recovery period. Definitive evidence on effectiveness of Mirena compared with more invasive procedures is lacking.

Abstract
BACKGROUND Helicobacter pylori infection is eradicated with antimicrobial agents and drug-resistant strains make successful treatment difficult. Geographical variations in virulence-factor genotype also exist. AIM To evaluate prevalence of drug resistance and virulence-factor genotype in Irish H. pylori strains and to investigate if there is any relationship between drug resistance and genotype. METHODS Helicobacter pylori strains isolated from 103 patients were examined. Antimicrobial susceptibilities were tested by Etest. The virulence-factor genotypes were determined using PCR. Frequencies of spontaneous metronidazole-resistance were measured in vitro. RESULTS Metronidazole resistance was present in 37.9% of strains examined. 16.5% of strains were clarithromycin-resistant and resistance to both agents observed was found in 12.6% of strains. 68% of strains were cagA(+). The dominant vacA type was s1/m2, followed by s1/m1 and s2/m2. The metronidazole resistance rate in cagA(-) group was significantly higher than in cagA(+) (P = 0.0089). Spontaneous resistance to metronidazole in cagA(-) occurred in higher frequency when compared with cagA(+). CONCLUSIONS cagA(+) and vacAs1/m2 type was the dominant genotype in Irish H. pylori strains. Significant rates of metronidazole resistance were observed in cagA(-) group. cagA(-) strains tend to acquire metronidazole resistance in vitro. Absence of cagA might be a risk factor in development of metronidazole resistance.

Abstract
Antibiotic resistance has resulted in unsatisfactory eradication results with dual and now triple therapy in many countries. Newer antibiotics and changes in dosing and duration of therapy may overcome resistant strains but may only provide limited improvement in eradication rates. Sequential therapy with amoxicillin (1 g twice a day) and a proton pump inhibitor (PPI) (twice a day) given for 5 days followed by a PPI plus clarithromycin (500 mg twice a day) and tinidazole (500 mg twice a day) for 5 days is now a first-line therapy for Helicobacter pylori in some countries. Standard triple therapy is effective in regions where clarithromycin resistance is low. Levofloxacin based triple therapy is an effective alternative to quadruple therapy in second-line treatment. Adjuvant therapy may reduce side-effects and improve compliance. Molecular and genomic research on H. pylori may result in the development of targeted antibiotic therapy; however, more research is required in this field. Further research in vaccination is also necessary before this can become an option in clinical practice.

Abstract
AIMS To examine prescription patterns of nonsteroidal anti-inflammatory drugs (NSAIDs) or analgesics in patients prescribed chronic rofecoxib treatment prior to withdrawal from the Irish market, and to determine the impact on proton pump inhibitor (PPI) co-prescription. METHODS Using a national prescribing database, adults (> or =16 years) prescribed rofecoxib for > or =3 months, but not analgesics, from January to September 2004 were identified. A longitudinal prescribing history was used to determine switching patterns to other cyclooxygenase (COX)-2 inhibitors, NSAIDs or analgesics during 3 and 12 months after withdrawal. Concomitant PPI prescription was examined. Logistic regression was used to determine the likelihood of switching to a COX-2 inhibitor vs. nonselective NSAID and factors influencing concomitant PPI prescription. RESULTS After rofecoxib withdrawal, 30.2% (1558) and 17.9% (922) of the 5155 study subjects received no further NSAID prescription during 3 and 12 months, respectively. During the 12-month period, approximately one-third of NSAID prescriptions were for <3 months; 40.7% (2096) received sequential prescriptions for different NSAIDs. Co-prescription of analgesics occurred in 49.3% (2539) of subjects. Neither age nor gender influenced the type of NSAID prescribed in the 12 months post rofecoxib withdrawal. PPI prescription increased by 5.5% during the study, associated with use of nonselective NSAIDs, prior use of PPIs and increasing age. CONCLUSIONS The majority of those receiving chronic rofecoxib therapy were prescribed either no further NSAID or short-term NSAID therapy only during the 12 months post withdrawal, which suggests the subsequent controversy may have encouraged prescribers to adhere more closely to published guidelines.

Abstract
OBJECTIVE 6-Thioguanine has been used as an alternative immunomodulator in the treatment of inflammatory bowel disease but data on its efficacy and safety are limited. The aim of this study was to analyse our experience of the efficacy and safety of 6-thioguanine in inflammatory bowel disease. MATERIAL AND METHODS Patients attending the inflammatory bowel disease clinic who were started on 6-thioguanine therapy were included in this prospective observational study. Indications for initiating 6-thioguanine therapy and other related clinical, pharmacological and laboratory parameters prior to and during therapy were recorded to determine the efficacy and safety of 6-thioguanine. RESULTS A total of 40 patients were treated with 6-thioguanine, 28 with Crohn's disease, 10 with ulcerative colitis and 2 with indeterminate colitis, at a fixed daily dose of 40 mg and continued for a median duration of 34 weeks (range 2-90 weeks). The indications for 6-thioguanine therapy included previous clinical resistance to thiopurine analogues (n=21), intolerance to thiopurine analogues (n=8) and de novo 6-thioguanine use in steroid refractory disease (n=11). Disease remission was reached in 44%, 73% and 89% of these patient groups at 3, 6 and 12 months, respectively. Inflammatory markers and steroid use were significantly lower during 6-thioguanine therapy compared with in the period before therapy. Therapy was discontinued in 13 patients (33%), mainly because of thrombocytopenia and associated hepatotoxicity. CONCLUSIONS 6-Thioguanine is a useful addition to treatment in inflammatory bowel disease but the frequent occurrence of hepatotoxicity limits its routine use.

BACKGROUND Optimal management approach is not well defined for subjects who fail initial first- and second-line Helicobacter pylori eradication attempts and are dealt on a case-by-case basis by the specialists. AIM To evaluate the efficacy and safety of standard and 'rescue' eradication therapies at primary and secondary care levels. METHODS H. pylori infected dyspepsia patients referred to our C13 urea breath testing laboratory between January 1999 to February 2002 were included. Eradication failure at secondary care level was treated using strategies including antibiotic sensitivity testing and the use of rifabutin- and furazolidone-based therapies. RESULTS 3280 patients received standard first-line eradication therapy, which was successful in 2530 (77%) patients. Second-line therapy (bismuth-based 'quadruple') or triple therapy (altering constituent antibiotics) was successful in 56% of 270 treated patients. Subsequent eradication attempts using rifabutin-based (n = 34) and furazolidone-based (n = 10) regimens were successful in 38% and 60% patients respectively. H. pylori eradication rates were significantly different for guidelines compliant (94.8%) and non-compliant (82%) groups (P = 0.0001). H. pylori eradication rates for non-ulcer dyspepsia (40%) and peptic ulcer disease (36%) were not significantly different. CONCLUSIONS Available H. pylori eradication therapies remain very effective and compliance to guidelines achieves high success rates. Furazolidone-based 'rescue' regimen achieved high eradication rates after failure of the standard first-line, second-line and rifabutin-based therapies.

Abstract
BACKGROUND Claims have been made that breast augmentation induces a previously unrecognized disease ("silicone-osis"). AIMS To confirm the existence of "silicone-osis", qualify and quantify its characteristics. METHODS In this population-based retrospective cohort study, the health status of 458 female Sydney residents who had augmentation mammoplasty for cosmetic reasons ("augmentation mammoplasty-exposed" or "exposed" cohort) between 1979 and 1983 was compared with the health status of 687 female Sydney residents who had non-silicone-associated plastic surgery ("augmentation mammoplasty-nonexposed" or "non-exposed" cohort). Both groups were matched for age (+/- 5 years), year of plastic surgery (+/- 2 years), plastic surgeon, anaesthetist and mode of anaesthesia. Outcome measures comprised dummy symptoms to assess reporting bias, as well as symptoms and symptom clusters from a comprehensive 78-symptom list. RESULTS Dummy variables were not over-reported by the exposed cohort. The following individual symptoms developed more commonly in the exposed cohort after index plastic surgery: "memory loss/confusion", "altered bowel habit", "chest pain made worse by deep breathing", "shortness of breath after walking up 10 steps", "breast pain", "sweating mainly at night" and "tunnel vision". Of eight identified symptom clusters, three were rejected as biologically unimportant: "joint swelling of the bunion joint", "haemorrhoids" and "breast lumps" (the latter two occurring more commonly in the non-exposed cohort). In contrast, five symptom clusters were thought to have potential biological importance and occurred more commonly in the exposed cohort. The symptom "night sweats" was common to all five clusters, and comprised the sole symptom in one instance. The other four multisymptom clusters were also characterized by "low energy" (lethargy) and "pins and needles", whereas "breast pain", "impaired memory", "muscle pain" and "reflux", occurred in three of the four clusters. CONCLUSION Cluster analysis suggested the existence of a multisystem disorder occurring more commonly in the exposed cohort and characterized by night sweats, lethargy, breast pain, impaired mentation, reflux, paraesthesiae, hand muscle weakness and myalgia. The argument against this being a new disease entity --"silicone-osis"-- however, was its presence, albeit at lower frequency, in the silicone-unexposed cohort. Thus this study did not confirm the existence of a new disease entity "silicone-osis" uniquely and causally associated with silicone exposure. The possible interpretations of these findings are discussed.

Abstract
BACKGROUND AND AIM Chronic radiation proctopathy is a troublesome complication of radiotherapy to the pelvis, for which current treatment modalities are unsatisfactory. The present prospective study was designed to determine the usefulness and safety of argon plasma coagulation in the management of chronic radiation proctopathy. METHODS Twenty-five consecutive patients (M:F 24:1, mean age: 69 years) with radiation proctopathy were prospectively included. All patients received argon plasma coagulation by a standard protocol. Response to treatment was assessed by symptom response, bleeding severity score, hematological parameters and transfusion requirements over a median 14-month follow up. RESULTS Patients received a median of one treatment session with argon plasma coagulation. There was significant improvement in rectal bleeding in all patients, with complete cessation of bleeding in 21 (81%) of the patients. The median bleeding severity score fell from 3 to 0 (P < 0.0005). The mean hemoglobin level rose from 10.05 +/- 2.21 g/dL before treatment to 12.44 +/- 1.09 g/dL at 6 months following treatment (P < 0.002). There was also improvement in other symptoms such as urgency and diarrhea. Over the period of follow up, there was no recurrence of anemia and no complications were noted. CONCLUSION These results suggest that argon plasma coagulation is a safe and effective modality in the treatment of chronic radiation proctopathy.

Abstract
BACKGROUND Allegations that exposure to endogenous silicone, especially related to breast implants, might be causally related to connective tissue disease originated from case studies. More recent comparative studies have implied no such increased risk. The aims of the present study were to compare the prevalence and/or incidence of autoimmune and connective tissue disorders in a population-based cohort of female Sydney residents stratified by augmentation mammoplasty status. METHODS In this population-based retrospective cohort study, the health status of female Sydney residents who had augmentation mammoplasty for cosmetic reasons between 1979 and 1983 was compared with that of female Sydney residents who had non-silicone-associated plastic surgery over the same period. Both groups were matched for age (+/- 5 years), year of plastic surgery (+/- 2 years), plastic surgeon, anaesthetist and mode of anaesthesia. Outcome measures comprised rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, sicca symptoms polymyositis/ dermatomyositis, connective tissue disease overlap, digital vasospasm, abnormal nailfold capillaroscopy, elevated antinuclear antibody titre, carpal tunnel syndrome, tendonitis, osteoarthritis, psoriatic arthritis, livedo reticularis, thyroid disease, multiple sclerosis, axillary lymphadenopathy, fibromyalgia and breast carcinoma. RESULTS There was no difference in the occurrence of connective tissue diseases or connective tissue disease-related parameters, thyroid disorders, fibromyalgia or multiple sclerosis between cohorts. However, axillary adenopathy and low titre positive antinuclear antibody (ANA) occurred with a significantly greater frequency in the exposed cohort (odds ratio (OR) = 3.50, 95% confidence interval (CI) = 2.10-5.84 and OR = 1.29, 95% CI = 1.03-1.62, respectively). Axillary adenopathy correlated with capsular contracture (relative risk (RR) = 2.07, 95% CI = 1.22-3.51) and also the self-reported development of digital vasospasm (RR = 3.20, 95% CI = 1.46-7.03) after breast augmentation. CONCLUSIONS No association was found between augmentation mammoplasty exposure and various connective tissue diseases and/or their related features. However, axillary adenopathy and low titre ANA were detected more frequently in the exposed cohort. Women with axillary adenopathy were more likely to have breast capsular contracture and report digital vasospasm post-dating surgery. Given comparable frequencies of higher titre ANA of both cohorts, the finding of elevations of low titre ANA is of dubious clinical significance.

Abstract
BACKGROUND The continuing uncertainty about the silica-systemic sclerosis relationship led to the investigation of its role as a disease determinant in a large population-based study of systemic sclerosis. AIMS To compare the frequency, socioeconomic and educational status, age-specific prevalence and duration of occupational silica exposure in males with and without systemic sclerosis. To assess the temporal relationship between exposure and disease onset. To estimate disease latency. To compare disease characteristics between silica-exposed and non-silica-exposed male cases. METHODS The study was case-control in design. The exposure variable was occupational silica exposure as assessed by an occupational health officer blinded to case/control status and the outcome variable was systemic sclerosis. The employed instrument comprised either a standardised telephone questionnaire (interviewed cases and controls) or medical records (deceased or living-status-unknown cases). RESULTS Sixty of 160 cases (37.5%) and 11 of 83 (13.3%) controls had occupational silica exposure (OR=3.93; 1.84-8.54). Comparison of data between 64 interviewed cases and all controls demonstrated initial occupational silica exposure occurring before age 40, comparable educational status but significantly different cumulative socioeconomic status with cases being over-represented in semi-skilled and unskilled occupations. Cross-sectional 'current' occupational data underestimated cumulative silica exposure by more than 50%. Silica exposure uniformly preceded onset of second disease symptoms and disease diagnosis. In most, it also preceded onset of first disease symptoms. Disease latency approximated two decades. No disease features distinguished silica-associated systemic sclerosis from idiopathic systemic sclerosis. The duration of silica exposure in the interviewed silica-exposed cases did not significantly exceed that of silica-exposed controls. CONCLUSIONS Male systemic sclerosis displays socioeconomic dependence. Silica is a disease determinant in male systemic sclerosis, with disease features including a long latency and clinical characteristics indistinguishable from idiopathic disease. Cross-sectional 'current' occupational data underestimate cumulative occupational silica exposure.

Abstract
Menorrhagia is a well-recognized complication of inherited bleeding disorders. In the past, the only viable option for women who were unresponsive to medical therapy was hysterectomy. Endometrial ablation has been recently developed as an alternative therapy for these patients and is associated with decreased morbidity. We report the successful use of activated recombinant factor VII (FVIIa) and endometrial ablation in the treatment of excessive menstrual blood loss in a 34-year-old women with severe factor VII (FVII) deficiency. Recombinant FVIIa (40 microg/kg) was administered pre-operatively and every 6 h (20 microg/kg) for 24 h postoperatively. The procedure was uncomplicated with a 200 ml surgical blood loss. FVIIa was used because it allowed FVII replacement with a recombinant product and also has the ability to bind to tissue factor expressed at the site of vascular injury, resulting in site-specific thrombin generation. We believe that endometrial ablation with recombinant VIIa should be considered in patients with severe FVII deficiency and menorrhagia unresponsive to medical therapy.

Abstract
BACKGROUND Systemic sclerosis prevalence and mortality estimates have demonstrated wide variability. The sole Australian study published to date demonstrated high prevalence rates when compared to overseas estimates. The prevalence and mortality findings reported in this paper derive from a larger study which addressed the distribution and determinants of systemic sclerosis within Sydney. AIMS To determine systemic sclerosis prevalence and mortality rates within Sydney over 15 years, 1974-88. METHODS Cases were ascertained from multiple sources including death certificates, hospitals, physicians, vascular surgeons' and dermatologists' private practices, a systemic sclerosis self-help group and private medical laboratories. RESULTS Overall, 715 cases were identified. Females comprised 77% (95% CI: 74-80) of cases. Disease of the limited subtype accounted for 79% (95% CI: 76-82) of all systemic sclerosis, being relatively more frequent in living than deceased cases, and in females than males. Crude prevalence estimates appeared to rise between 1975 (4.52/100,000 95% CI:3.75-5.29/100,000) and 1988 (8.62/100,000 95% CI:7.64-9.60/100,000) as did estimates of diffuse disease. However, diffuse disease prevalence, when expressed as a proportion of total disease prevalence, showed no significant temporal change. Although crude mortality rates also showed apparent temporal increases (0.24/100,000 in 1975 to 0.80/100,000 in 1988) standardised mortality rates showed less convincing trends (0.41/100,000 in 1976 and 0.40/100,000 in 1988). Death certificate-derived mortality rates provided relatively large underestimates of total mortality. However, these underestimates were relatively constant over time. CONCLUSIONS This study has demonstrated systemic sclerosis prevalence and mortality rates comparable to overseas estimates, consistently higher prevalence and mortality rates in females than males, proportionally higher rates of diffuse disease in males than females and in deceased cases than living cases, a diffuse: limited disease ratio apparently stable over time, apparently increasing temporal prevalence and mortality rates and, by implication, rising incidence rates. The observed temporal rise in diffuse disease prevalence and the absence of a convincing fall in diffuse disease mortality suggests a rising temporal incidence rate of diffuse disease. Standardised mortality rates demonstrated less consistent trends than did crude mortality rates and failed to demonstrate convincing declines in mortality subsequent to the introduction of ACE inhibitors for management of systemic sclerosis renal disease. Death certificate-derived systemic sclerosis mortality rates considerably and consistently underestimated systemic sclerosis-all cause mortality.

Abstract
BACKGROUND Familial systemic sclerosis has been rarely reported. Assumptions have therefore been made implying no familial disease aggregation. This study critically challenges the assumption using a methodical population-based epidemiological approach to quantify the prevalence and characteristics of familial systemic sclerosis. METHODS In this retrospective cohort study the systemic sclerosis prevalence in first degree family members was compared between 715 systemic sclerosis patients (710 families) and 371 randomly ascertained age and gender group-matched general practice controls (371 families). These data, obtained by telephone questionnaire (living patients) or medical records review (deceased patients and untraceable patients of unknown living status), were validated, where necessary, and expressed in terms of relative risk, absolute risk and population point prevalence. RESULTS Systemic sclerosis affecting first degree members was validated in ten of 710 families. Reporting of systemic disease in another four more distant family members, and the co-occurrence of systemic and localised disease in three families was also documented. Observed and expected disease subtype concordance was 80% (44-97%) and 68% respectively and the female predominance among familial cases was similar to that for non-familial disease. The risk of disease in a subsequent first degree relative was compared to the risk in an initial first degree family member. Its estimated magnitude was wide (11-158). However, use of population prevalence data to determine the expected number of systemic sclerosis patients in the negative cohorts' families suggests the higher estimate is more realistic. Despite the high magnitude, the absolute disease risk in first degree family members remained low--approximating 1%. The population prevalence of familial systemic sclerosis approximated 1.4/million. CONCLUSIONS This study substantially increases the otherwise small list of documented instances of familial systemic sclerosis. More importantly, it quantifies the risk for the first time, ranking it as the disease's most powerful determinant identified to date.

Abstract
OBJECTIVES The main purpose of our study was to identify the patient characteristics of women undergoing hysterectomy and to estimate the proportion of hysterectomies that could be done vaginally by recognized surgical techniques. STUDY DESIGN The records of 500 women who underwent hysterectomy were reviewed. The characteristics of patients without an absolute contraindication to vaginal hysterectomy were analyzed. RESULTS Overall, 96 (19.2%) of our study group underwent vaginal hysterectomy. A total of 382 (76.4%) women were judged not to have an absolute contraindication to this route. The most frequent characteristics of this group were lack of uterine prolapse (76.4%), a myomatous uterus (44.5%), and a need for oophorectomy (43.2%). We did not exclude women who did not have significant uterine prolapse or a history of pelvic surgery or pelvic tenderness and we included those requiring oophorectomy or with a uterine size up to that of 14 weeks' gestation; with these criteria more than two thirds of the entire study population could undergo vaginal surgery. CONCLUSIONS To maximize the proportion of hysterectomies performed vaginally, gynecologists need to be familiar with surgical techniques for dealing with nonprolapsed uteri, uterine leiomyomas, and vaginal oophorectomy.

Abstract
OBJECTIVE To assess the efficacy of lignocaine spray during outpatient hysteroscopy in reducing the need for additional anesthesia and reducing the discomfort of the procedure. DESIGN A randomized double-blind, placebo-controlled trial. SETTING An undergraduate university teaching hospital in London. PATIENT(S) One hundred twenty patients undergoing outpatient hysteroscopy. INTERVENTION(S) Application of lignocaine spray to the cervix, cervical canal, and uterine cavity during outpatient hysteroscopy. MAIN OUTCOME MEASURE(S) The need to use additional anesthesia and the pain experienced at various steps of the procedure. RESULT(S) Women treated with active spray experienced significantly less pain when the cervix was grasped with a tenaculum at the start of hysteroscopy. There were no other significant differences in the outcome of hysteroscopy between the placebo and lignocaine groups, although there was a significant reduction in the use of additional anesthesia in both groups compared with historical controls. CONCLUSION(S) Lignocaine spray has beneficial effects on cervical but not uterine sensation. Pretreatment with either lignocaine or placebo seems to reduce the need for additional intracervical anesthesia during hysteroscopy.

Abstract
BACKGROUND The most frequent indication for hysterectomy is menorrhagia, even though the uterus is normal in a large number of patients. Transcervical resection of the endometrium (TCRE) is a less drastic alternative, but success rates have varied and menorrhagia can recur. We have tested the hypothesis that the difference in the proportion of women dissatisfied and requiring further surgery within 3 years of TCRE or hysterectomy would be no more than 15%. METHODS 202 women with symptomatic menorrhagia were recruited to a multicentre, randomised, controlled trial to compare the two interventions. TCRE and hysterectomy were randomly assigned in a ratio of two to one. The primary endpoints were women's satisfaction and need for further surgery. The patients' psychological and social states were monitored before surgery, then annually with a questionnaire. Analysis was by intention to treat. FINDINGS Data were available for 172 women (56 hysterectomy, 116 TCRE); 26 withdrew before surgery and four were lost to follow-up. Satisfaction scores were higher for hysterectomy than for TCRE throughout follow-up (median 2 years), but the differences were not significant (at 3 years 27 [96%] of 28 in hysterectomy group vs 46 [85%] of 54 in TCRE group were satisfied; p = 0.16). 25 (22%) women in the TCRE group and five (9%) in the hysterectomy group required further surgery (relative risk 0.46 [95% CI 0.2-1.1], p = 0.053). TCRE had the benefits of shorter operating time, fewer complications, and faster rates of recovery. INTERPRETATION TCRE is an acceptable alternative to hysterectomy in the treatment of menorrhagia for many women with no other serious disorders.

Abstract
OBJECTIVE To assess the feasibility and safety of vaginal removal of ovaries at the time of vaginal hysterectomy. DESIGN Prospective study. SETTING London teaching hospital. POPULATION Between March 1993 and March 1995, 40 women were admitted under the care of one consultant for vaginal hysterectomy and bilateral oophorectomy. METHODS The success rate of removing the ovaries vaginally was calculated and the operative time, blood loss, intra- and post-operative complications and patient recovery were analysed and compared with 48 patients who had a vaginal hysterectomy but retained their ovaries during the same time period. RESULTS Thirty-nine (97.5%) of the 40 women due to undergo removal of the ovaries were managed successfully via the vaginal route; one woman required laparoscopic removal of one of her ovaries containing an ovarian cyst which was not diagnosed pre-operatively. A variety of techniques were used for vaginal oophorectomy which included salpingo-oophorectomy, oophorectomy without salpingectomy, and transvaginal endoscopic oophorectomy utilising endoloop sutures or bipolar electrosurgery. Oophorectomy added a mean of 23.4 min (88.3 vs 64.9 min, 95% CI 10.2-36.7, P < 0.001) to the total operating time compared with vaginal hysterectomy alone. No laparotomies were required, and both the complication rate and post-operative inpatient stay were similar for the two groups. CONCLUSIONS The need to perform oophorectomy should not be considered a contraindication to vaginal hysterectomy.

Abstract
We have attempted to review the best available evidence for the commonest gynaecological endoscopic procedures. Controlled studies are the exception rather than the rule, and randomized studies are even rarer. Therefore, the results of large, uncontrolled series must be acknowledged. As a result, for most procedures, sufficient information is now available regarding indications, efficacy, and complications to determine their role in routine clinical practice.

Abstract
BACKGROUND Endometrial resection is an alternative to hysterectomy in the treatment of women with menorrhagia, but it may not control the condition. We sought to evaluate the effectiveness of such resection. METHODS We followed 525 consecutive women (mean age at initial surgery, 42 years) for up to five years after endometrial resection. The women were examined 6 to 12 weeks after the operation and were then sent yearly questionnaires seeking information about their condition. The mean duration of follow-up was 31 months. Thirty-seven women (86 percent of the 43 women available for five years of follow-up) were followed for the entire period. RESULTS Endometrial resection was completed successfully in 95 percent of the women, with operative complications in 6 percent. Forty-eight women underwent subsequent resection. The yearly questionnaires indicated that 85 to 100 percent of the women (depending on the year of follow-up) had adequately controlled menorrhagia, 26 to 40 percent had amenorrhea, 71 to 80 percent reported either a lessening of menstrual pain or no pain, and 79 to 87 percent were satisfied with the results of their surgery. No further surgery was needed by 80 percent of the women, and only 9 percent underwent hysterectomy during the five years of follow-up, with 98 percent of those operations being performed in the first three postoperative years. CONCLUSIONS Endometrial resection is an effective alternative to hysterectomy in women with menorrhagia.

Abstract
OBJECTIVE To evaluate the feasibility and acceptability of outpatient diagnostic hysteroscopy. METHODS The outcome of 2500 consecutive outpatient hysteroscopies was analyzed. Cervical dilation was performed when necessary and local anesthesia was not administered routinely. Endometrial biopsy and minor hysteroscopic procedures were carried out when indicated. Findings and outcome were compared according to patient characteristics. RESULTS The most common indication for hysteroscopy was abnormal uterine bleeding (87%). Hysteroscopy was performed successfully in 96.4%, and a complete view of the uterine cavity was obtained in 88.9%. Local anesthesia was used in 29.8% and was associated with the need for cervical dilation; both local anesthetic use and cervical dilation were significantly more often required in nulligravid, nulliparous, and postmenopausal women. Intrauterine pathology was diagnosed in 48%, the highest incidence being found in those 50-60 years old (53.7%). The presence of fibroids was the most common abnormality (24.3%) but was seen in only 6.8% of women older than 60 years. Conversely, the incidence of endometrial polyps increased with age, up to 20.5% in women over 60 years. Endometrial biopsy was performed in 68% and produced adequate tissue for histologic examination in 83.7%. Endometrial hyperplasia or carcinoma was detected in 1%. One hundred sixteen women (4.6%) underwent a minor hysteroscopic procedure. CONCLUSION Outpatient diagnostic hysteroscopy is both feasible and acceptable in the overwhelming majority of cases, with a high detection rate for intrauterine pathology. This procedure may become as routine in the 21st century as D&C has been in the 20th.

Abstract
OBJECTIVE To determine the role of outpatient diagnostic hysteroscopy in patients with abnormal uterine bleeding (AUB) on hormone replacement therapy (HRT) and to contrast this with a control group of women presenting with postmenopausal bleeding. DESIGN Comparative observational study. SETTING Outpatient hysteroscopy clinic in a university hospital. PATIENTS Three hundred ten patients undergoing outpatient hysteroscopy. INTERVENTIONS Outpatient diagnostic hysteroscopy with endometrial biopsy when indicated. MAIN OUTCOME MEASURES Hysteroscopic findings, need for cervical dilatation and local anaesthesia, correlation between hysteroscopy and histologic diagnosis. RESULTS There were 157 (7.1%) patients with AUB on HRT and another 153 (6.9%) with postmenopausal bleeding out of 2,203 outpatient hysteroscopies. Hysteroscopy was successful in 97% and 92% of patients, respectively, and intrauterine pathology was diagnosed in 46.7% and 39.7% of these cases. Functional endometrium was noted significantly more often with HRT and endometrial atrophy with postmenopausal bleeding. Overall, local anesthesia was used in 126 (40.6%) and shown to be associated significantly with the need for cervical dilatation. Endometrial biopsy was attempted in 125 (80%) and 119 (78%) patients in the study and control groups, but was unsuccessful significantly more often with postmenopausal bleeding (38.7%) versus 16%). There were six cases of endometrial carcinoma, all in the control group. CONCLUSION There is a high incidence of intrauterine abnormalities in women with menstrual symptoms while taking HRT, but the pathology differed from those with postmenopausal bleeding. As focal lesions are found commonly in such patients, their detection by diagnostic hysteroscopy should improve compliance with HRT as it would allow individualization of treatment.

Abstract
OBJECTIVE To assess the feasibility and safety of performing vaginal hysterectomy on enlarged uteri the equivalent of 14 to 20 weeks of gestation in size. DESIGN A prospective observational study. SETTING The Royal Free Hospital, London. PARTICIPANTS Fourteen consecutive women undergoing vaginal hysterectomy for uterine fibroids up to 20 weeks in size. INTERVENTIONS Vaginal hysterectomy with or without bilateral salpingo-oophorectomy or oophorectomy. MAIN OUTCOME MEASURES Uterine size and weight, techniques used to reduce uterine size, surgical outcome, operative time, estimated operative blood loss, intra- and post-operative complications, duration of hospitalisation. RESULTS The mean uterine size was 16.3 weeks (range 14 to 20 weeks). All hysterectomies were completed successfully by the vaginal route. The uteri weighed 380 to 1100 g, with a mean of 638.7 g. Bisection combined with myomectomy and morcellation were used in most cases to obtain reduction in uterine size, whereas coring was only utilised in two cases. The mean operating time was 84.3 min with a range of 30 to 150 min. The only complications were transient haematuria (n = 6) and superficial vaginal grazes (n = 5). One of the women required a blood transfusion. The mean post-operative hospital stay was 3.7 days (range 2 to 9 days). CONCLUSION Enlargement of the uterus to a size equivalent to 20 weeks of gestation should no longer be considered a contraindication to vaginal hysterectomy. Many more hysterectomies should be carried out vaginally without resorting to abdominal or laparoscopic surgery.

Abstract
OBJECTIVE To evaluate patient acceptance and the clinical feasibility of carbon dioxide compared with normal saline for uterine distension in outpatient hysteroscopy. DESIGN Prospective, randomized clinical trial. SETTING Outpatient hysteroscopy clinic in a university hospital. PATIENTS One hundred fifty-seven patients undergoing outpatient hysteroscopy. INTERVENTIONS Outpatient hysteroscopy was performed with carbon dioxide or normal saline with endometrial biopsy when indicated. MAIN OUTCOME MEASURES Need for local anesthesia, cervical dilatation, view of uterine cavity, need to change from carbon dioxide to normal saline distension, procedure time, patient discomfort (lower abdominal pain, shoulder tip pain, nausea) and complications. RESULTS Carbon dioxide was used for uterine distension in 79 women and normal saline was used in 78. Cervical dilatation was required more often with carbon dioxide hysteroscopy, although there was no increased requirement for local anesthesia. Hysteroscopic vision was similar between the two media, but eight carbon dioxide cases had to be converted to liquid distension. Procedure times were significantly longer for carbon dioxide hysteroscopy as was the occurrence of bubbles during the procedure. Lower abdominal pain and shoulder tip pain were significantly worse with carbon dioxide distension. Although the incidence of nausea and vomiting was higher with the use of carbon dioxide, the differences did not achieve statistical significance. CONCLUSION The use of normal saline for uterine distension had no adverse affects on the hysteroscopic view. It provided a shorter operating time and was well accepted by patients. Because of its easy availability and low cost, normal saline is an excellent alternative to carbon dioxide in women undergoing outpatient hysteroscopy.

Abstract
A prospective randomised trial comparing propranolol and sclerotherapy to sclerotherapy alone was conducted over a 2-year follow up in a district hospital setting of unselected patients. Rebleeding and survival were analysed. Thirty-nine patients were randomised to propranolol plus sclerotherapy and 34 to sclerotherapy alone. The two groups were clinically comparable. There was no significant difference in the cumulative percent of patients free of rebleeding; 54% of the sclerotherapy group rebled compared to 52% of the group treated with propranolol plus sclerotherapy (Hazard ratio 1.09 (0.54-2.22) and p = 0.81, NS). Two-year actuarial survival was also not significantly different, with 77% of the propanolol plus sclerotherapy group surviving, compared to 74% of sclerotherapy alone (Hazard ratio 1.08 (0.35-2.22) and p = 0.79, NS). The mean time to eradication of varices was not significantly different between the two groups (propranolol plus sclerotherapy 222 days, sclerotherapy alone 243 days), nor did the rate of variceal recurrence differ (72.7 vs 72 days). This study did not show long-term improvement in rebleeding or survival using propranolol in addition to a regular sclerotherapy programme.
