Excisional treatment comparison for in situ endocervical adenocarcinoma (EXCISE): A phase 2 pilot randomized controlled trial to compare histopathological margin status, specimen size and fragmentation after loop electrosurgical excision procedure and cold knife cone biopsy.

OBJECTIVE: Adenocarcinoma in situ (AIS) of the cervix is a precursor to cervical adenocarcinoma. When AIS is detected by cervical screening an excision biopsy is mandatory to exclude invasion. We aimed to compare margins status, specimen size and fragmentation after loop electrosurgical excision procedure (LEEP) and 'cold knife cone biopsy' (CKC). METHODS: The EXCISE Trial was an investigator-initiated, multicenter, open-label, parallel-group, phase 2, randomized study. Patients were enrolled at seven hospitals in Australia and New Zealand. We randomly assigned women aged ≥18 to ≤45 years with screen detected AIS to LEEP or CKC. Co-primary endpoints were margin status, specimen size and fragmentation. Analysis was by intention-to-treat. RESULTS: Between August 2, 2017 and September 6, 2019, 40 patients were randomly assigned 2:1 to LEEP or CKC. Margin status was evaluable in 36 cases. The proportion of patients with involved margins did not differ between groups. 25 of 26 LEEP and all 14 CKC biopsies were excised as single specimens (p = 1·00). There were no differences in specimen dimensions. Patients in the CKC group had more post-operative complications (64.3% compared to 15.4% for LEEP p = ·00). There were no differences in grade three complications (p = ·65). CONCLUSIONS: LEEP was not associated with a greater likelihood of positive margins, specimen fragmentation or smaller excision compared to CKC when performed according to a standardized protocol. However, the study was not powered to establish non-inferiority of LEEP and a definitive phase 3 trial to compare margin status and rates of treatment failure after LEEP and CKC is warranted.

LLETZ make it simple: Anxiety, pain and treatment outcomes with outpatient large loop excision of the transformation zone under local anaesthesia.

BACKGROUND: Large loop excision of the transformation zone (LLETZ) is the preferred treatment for cervical intraepithelial neoplasia due to its effectiveness and ability to be performed in an outpatient setting under local anaesthesia (LA). Although current guidelines recommend that most LLETZ can be performed under LA, there is paucity in clinical data of patients' perspectives of outpatient LLETZ. AIM: Determining patient acceptability of outpatient LLETZ through assessment of anxiety and pain scores, and comparing treatment outcomes with current standards in terms of margins status, negative histology, short-term morbidity rates and follow-up attendance. MATERIALS AND METHODS: This study was conducted at a tertiary hospital over two years (2014-2016). Patients undergoing outpatient LLETZ completed a three-part questionnaire (before, immediately after and 4-6 weeks post-procedure). RESULTS: One hundred and five patients underwent outpatient LLETZ. Mean pain score was 2 (range 0-8). Pre-procedure anxiety was common but most resolved post-procedure. Women who did not have a prior LLETZ discussion were more likely to report moderate-severe anxiety levels pre-procedure, compared with women who did (odds ratio 3.00, 95% CI 1.11-8.09, P = 0.030). There were no differences found in pain scores when comparing pre-procedure anxiety levels, prior discussion of LLETZ or mode of anaesthesia. Specimen margins were involved in 42.9%. No association was found between positive cervical margin status and age, pre-procedure anxiety or post-procedure pain scores. Most patients were satisfied and attended follow-up appointments. CONCLUSION: Large loop excision of the transformation zone under LA is a well-tolerated procedure with high satisfaction and follow-up rates. Clinicians need to initiate early discussions regarding treatment to minimise procedure-related anxiety.

Risk of venous thromboembolism in women taking the combined oral contraceptive: A systematic review and meta-analysis.

BACKGROUND: Much scientific, media and patient interest surrounds the risk of venous thromboembolism (VTE) in women taking combined oral contraceptives (COCs). OBJECTIVE: We conducted a systematic review and meta-analysis to assess VTE risk in women taking COCs, focusing on drospirenone. METHODS: Literature searches of clinical studies on COCs in which VTE was reported were undertaken in May 2015. No overall estimate of VTE risk between drospirenone-containing COCs and other COCs was produced because of heterogeneity of the study designs. RESULTS: The final review and meta-analysis included 15 studies. No increased risk of VTE with drospirenone was seen in prospective or case control studies, but the risk of VTE was increased in retrospective cohort and nested case control studies. DISCUSSION: The difference in risk of VTE based on the choice of progestin in COCs is, at worst, very small in absolute terms and should not be the sole factor considered when choosing the 'right' COC for each woman.

Applying process mapping and analysis as a quality improvement strategy to increase the adoption of fruit, vegetable, and water breaks in Australian primary schools.

Over the past decade, public health policy in Australia has prioritized the prevention and control of obesity and invested in programs that promote healthy eating-related behaviors, which includes increasing fruit and vegetable consumption in children. This article reports on a study that used process mapping and analysis as a quality improvement strategy to improve the delivery of a nutrition primary prevention program delivered in primary schools in New South Wales, Australia. Crunch&Sip® has been delivered since 2008. To date, adoption is low with only 25% of schools implementing the program. We investigated the cause of low adoption and propose actions to increase school participation. We conducted semistructured interviews with key stakeholders and analyzed the process of delivering Crunch&Sip to schools. Interviews and process mapping and analysis identified a number of barriers to schools adopting the program. The analyses identified the need to simplify and streamline the process of delivering the program to schools and introduce monitoring and feedback loops to track ongoing participation. The combination of stakeholder interviews and process mapping and analysis provided important practical solutions to improving program delivery and also contributed to building an understanding of factors that help and hinder program adoption. The insight provided by this analysis helped identify usable routine measures of adoption, which were an improvement over those used in the existing program plan. This study contributed toward improving the quality and efficiency of delivering a health promoting program to work toward achieving healthy eating behaviors in children.

Integrating parental leave into specialist training: experience of trainees and recently graduated RANZCOG Fellows.

OBJECTIVES: To ascertain the views of trainees and recently graduated Fellows of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists on their experiences of taking parental leave during specialist training. DESIGN: An anonymous online survey, conducted over a 1-month period from 16 August 2012 to 14 September 2012, of participants' experiences of taking parental leave and of the effects of parental leave taken by trainee colleagues on participants' own training. SETTING AND PARTICIPANTS: All trainees undertaking training for the Fellowship of the College, and all Fellows who had graduated in the past 6 years were invited to take part. Of the total 1051 invitees, 261 responded to the survey. MAIN OUTCOME MEASURES: Ease with which parental leave was granted, ability to return to a training post after taking leave, and participants' experiences of views expressed about parental leave in the work environment. RESULTS: Most participants requesting parental leave were able to access it and return to a training post; however, a small proportion experienced difficulties. Among female respondents who had taken parental leave, 28 (26.2%) reported being asked about their intentions for future pregnancy during the training application process, and 45 (42.1%) reported receiving negative comments about this in the work environment. CONCLUSIONS: While in most instances parental leave is accessible automatically, a small but significant number of trainees reported encountering difficulties. These matters are being addressed within our own College, and our results are likely to be relevant to all bodies involved in postgraduate medical training, particularly given the increasing feminisation of the medical workforce.

Evaluation framework for translational research: case study of Australia's get healthy information and coaching service(R).

The Get Healthy Information and Coaching Service® (GHS), a free government-funded telephone-delivered information and coaching service was launched in February 2009 by the Australian New South Wales state government. It represents the translation of research evidence applied in the real world (T4 or Phase 4 translation), aimed at addressing the modifiable risk factors associated with the overweight and obesity. In controlled settings, it has been established that telephone-based lifestyle counseling programs are efficacious in reducing anthropometric and behavioral risk factors. This article presents the GHS case study as a population-wide intervention and describes the quasi-experimental evaluation framework used to evaluate both the process (statewide implementation) and impact (effectiveness) of the GHS in a real-world environment. It details the data collection, measures, and statistical analysis required in assessing the process of implementation-reach and recruitment, marketing and promotion, service satisfaction, intervention fidelity, and GHS setting up and operations costs-and in assessing the impact of GHS-increasing physical activity, improving dietary practices, and reducing body weight and waist circumference. The comprehensive evaluation framework designed for the GHS provides a method for building effectiveness evidence of a rare translation of efficacy trial evidence into population-wide practice.

The relationship between annual hospital volume of trauma patients and in-hospital mortality in New York State.

BACKGROUND: Several studies in the literature have examined the volume-outcome relationship for trauma, but the findings have been mixed, and the associated impact of the trauma center level has not been examined to date. The purposes of this study are to (1) determine whether there is a significant relationship between the annual volume of trauma inpatients treated in a trauma center (with "patients" defined in multiple ways) and short-term mortality of those patients, and (2) examine the impact on the volume-mortality relationship of being a Level I versus Level II trauma center. METHODS: Data from New York's Trauma Registry in 2003 to 2006 were used to examine the impact of total trauma patient volume and volume of patients with Injury Severity Score (ISS) of at least 16 on in-hospital mortality rates after adjusting for numerous risk factors that have been demonstrated to be associated with mortality. RESULTS: The adjusted odds of in-hospital mortality patients in centers with a mean annual volume of less than 2,000 patients was significantly higher (adjusted odds ratio = 1.46, 95% confidence interval, 1.25-1.71) than the odds for patients in higher volume centers. The adjusted odds of mortality for patients in centers with an American College of Surgeons-recommended annual volume of less than 240 patients with an ISS of at least 16 was 1.41 times as high (95% confidence interval, 1.17-1.69) as the odds for patients in higher volume centers. However, for both volume cohorts analyzed, the variation in risk-adjusted in-hospital mortality rate was greater among centers within each volume subset than between these volume subsets. CONCLUSION: When considering the trauma system as a whole, higher total annual trauma center volume (2,000 or higher) and higher volume of patients with ISS ≥16 (240 and higher) are significant predictors of lower in-hospital mortality. Although the American College of Surgeons-recommended 1,200 total volume is not a significant predictor, hospitals in New York with ISS ≥16 volumes in excess of 240 also have total volumes in excess of 2,000. However, when considering individual trauma centers, high volume centers do not consistently perform better than low volume centers. Thus, despite the association between volume and mortality, we believe that the most accurate way to assess trauma center performance is through the use of an accurate, complete, comprehensive database for computing center-specific risk-adjusted mortality rates, rather than volume per se.

Physical activity policies and practices of childcare centres in Australia.

AIM: The aim of this study was to describe the physical activity-related policies and practices of childcare services; and to determine if service size, socioeconomic or remoteness characteristics predict such policies and practices. METHODS: Authorized supervisors of 216 licensed pre-schools and long day care centres participated in a brief telephone survey. RESULTS: Few services had a written physical activity policy, programmed time each day for fundamental movement skill development, or had staff trained in physical activity. Twenty-eight percent of pre-schools and 30% of long day care centres provided daily opportunities for children 3-5 years to participate in sedentary screen activities. Rural pre-schools and long day care centres were more likely to program time for fundamental movement skills development, as were pre-schools from higher socioeconomic areas. CONCLUSIONS: There is substantial scope for childcare services to modify their policies and practices to be more supportive of child physical activity.

Persistent psychological distress in resettled refugee women-at-risk at one-year follow-up: Contributions of trauma, post-migration problems, loss, and trust.

The mental health of women has been largely neglected in the refugee literature, notwithstanding the specific gender-related issues that confront women seeking asylum. Furthermore, a specific category of women, deemed to be women-at-risk, face particular challenges in their journey and resettlement process. This longitudinal study investigated psychological distress in refugee women-at-risk one year after resettlement in Australia. Follow-up survey of 83 women-at-risk (mean age = 33.41 years; SD = 11.93) assessed: trauma events and symptoms; loss events and loss distress; level of post-migration problems; anxiety, depression, and somatic symptoms; and absence of trust in community members. Participants demonstrated no symptom change since initial assessment (p > .05). Substantial proportions of women reported traumatization (39%), PTSD (20%), anxiety (32%), and depression (39%) above clinical cut-offs, and high levels of somatization and loss distress. Post-migration problems, trauma events, and region of birth were associated with all symptoms, with post-migration problems the strongest predictor. Absence of trust in community members was associated with trauma, depression, and somatic symptoms. Initial trauma and somatic symptoms were associated with follow-up traumatic and somatic symptoms. Loss and trauma events were associated with loss distress. Findings underline the role of post-migration problems on psychological distress and the need to consider women's psychological wellbeing in the context of their trauma and loss history, potential impacts of ethnicity, and complex socio-cultural dynamics underpinning issues of trust within communities. Effective service delivery requires that practitioners screen for and address psychological distress in women-at-risk at least up to 18 months after resettlement.

Munch and Move: evaluation of a preschool healthy eating and movement skill program.

BACKGROUND: Early childhood services have been identified as a key setting for promoting healthy eating and physical activity as a means of preventing overweight and obesity. However, there is limited evidence on effective nutrition and physical activity programs in this setting. The purpose of this study was to evaluate Munch and Move, a low-intensity, state-wide, professional development program designed to support early childhood professionals to promote healthy eating and physical activity among children in their care. METHODS: The evaluation involved 15 intervention and 14 control preschools (n = 430; mean age 4.4 years) in Sydney, New South Wales, Australia and was based on a randomised-control design with pre and post evaluation of children's lunchbox contents, fundamental movement skills (FMS), preschool policies and practices and staff attitudes, knowledge and confidence related to physical activity, healthy eating and recreational screen time. RESULTS: At follow up, FMS scores for locomotor, object control and total FMS score significantly improved by 3.4, 2.1 and 5.5 points more (respectively) in the intervention group compared with the control group (P < 0.001) and the number of FMS sessions per week increased by 1.5 (P = 0.05). The lunchbox audit showed that children in the intervention group significantly reduced sweetened drinks by 0.13 serves (i.e., 46 ml) (P = 0.05). CONCLUSION: The findings suggest that a low intensity preschool healthy weight intervention program can improve certain weight related behaviours. The findings also suggest that change to food policies are difficult to initiate mid-year and potentially a longer implementation period may be required to determine the efficacy of food policies to influence the contents of preschoolers lunchboxes.

The Sydney Diabetes Prevention Program: a community-based translational study.

BACKGROUND: Type 2 diabetes is a major public health problem in Australia with prevalence increasing in parallel with increasing obesity. Prevention is an essential component of strategies to reduce the diabetes burden. There is strong and consistent evidence from randomised controlled trials that type 2 diabetes can be prevented or delayed through lifestyle modification which improves diet, increases physical activity and achieves weight loss in at risk people. The current challenge is to translate this evidence into routine community settings, determine feasible and effective ways of delivering the intervention and providing on-going support to sustain successful behavioural changes. METHODS/DESIGN: The Sydney Diabetes Prevention Program (SDPP) is a translational study which will be conducted in 1,550 participants aged 50-65 years (including 100 indigenous people aged 18 years and older) at high risk of future development of diabetes. Participants will be identified through a screening and recruitment program delivered through primary care and will be offered a community-based lifestyle modification intervention. The intervention comprises an initial individual session and three group sessions based on behaviour change principles and focuses on five goals: 5% weight loss, 210 min/week physical activity (aerobic and strength training exercise), limit dietary fat and saturated fat to less than 30% and 10% of energy intake respectively, and at least 15 g/1000 kcal dietary fibre. This is followed by 3-monthly contact with participants to review progress and offer ongoing lifestyle advice for 12 months. The effectiveness and costs of the program on diabetes-related risk factors will be evaluated. Main outcomes include changes in weight, physical activity, and dietary changes (fat, saturated fat and fibre intake). Secondary outcomes include changes in waist circumference, fasting plasma glucose, blood pressure, lipids, quality of life, psychological well being, medication use and health service utilization. DISCUSSION: This translational study will ascertain the reach, feasibility, effectiveness and cost-effectiveness of a lifestyle modification program delivered in a community setting through primary health care. If demonstrated to be effective, it will result in recommendations for policy change and practical methods for a wider community program for preventing or delaying the onset of type 2 diabetes in high risk people.

Parental perceptions of barriers to children's participation in organised sport in Australia.

AIM: To examine parents' perceptions on how cost, time, travel and the variety of organised sporting activities influence their decisions to allow their child to participate in organised sport; and recent expenditure on sport-related items for their child. METHODS: Computerised assisted telephone interviews survey of 402 parents of children aged 5-17 years old living in New South Wales, Australia. RESULTS: Overall, 63% of children participated in organised sporting activities. Multivariate analysis shows that for parents of 5-12-year old children, the decision to allow their child to participate in organised sports was strongly influenced by time (P < 0.00). The financial costs associated with a child's participation in organised sports influenced families with lower incomes (p = 0.01) and with girls (p=0.04), while for rural families the option of a wider variety of local sporting activities influenced decisions about their child's participation in organised sport (p=0.05). Footwear/uniforms were the main sporting related expense. Sydney parents were more likely to report sport related expenditures for their child (P < 0.01). CONCLUSIONS: Sporting costs, variety and time commitments influenced parents' decisions about their child's participation in organised sport. These factors indicate the need for initiatives to promote access to organised sports through reducing costs and increasing variety, particularly for families with lower incomes and are living in rural and regional areas.

The attitudes of Australian gynaecologists to HPV vaccination: an ASCCP survey.

BACKGROUND: With human papilloma virus (HPV) vaccines now approved for women up to 45 years of age, gynaecologists in Australia will be approached increasingly for advice on whether to have the HPV vaccine. AIM: We seek to establish the attitudes of gynaecologists to HPV vaccination when advising women in various age groups. METHODS: Fellows, members and trainees of Royal Australian and New Zealand College of Obstetricians and Gynaecologists were approached in early 2009 to complete an Australian Society for Colposcopy and Cervical Pathology survey, which they could return by post or internet on-line. There were 836 (49.0%) responses, with 35.6% of responders using 'Tuna' on-line. RESULTS: 836 RANZCOG fellows, members and trainees responded to the survey. The gender of responders are 261 (43%) females and 470 (56%) males. Of the responders, 391 (46.8%) usually initiated discussion regarding the role of HPV vaccination with their patients. More than 93% encourage when recommending the HPV vaccines for female responders aged 12-26 years. This proportion decreased to 66% for women aged 27-45 years, with 15% strongly encouraging vaccination for this age group. The attitudes to HPV vaccination for the different age groups of females were similar for trainees, fellows and members, as well as for gender and age groups of the responders. However, those with lower level of knowledge are less likely to encourage HPV vaccination in all vaccination age groups and the association is statistically significant after adjusting for role, gender and age. CONCLUSIONS: The results show a strong support from gynaecologists in Australia for HPV vaccination.

Parental awareness and attitudes of food marketing to children: a community attitudes survey of parents in New South Wales, Australia.

AIM: To determine parents' attitudes and awareness of food marketing to children. METHOD: Computer-assisted telephone interviews of a random sample of 400 parents of children aged 5-17 years and who were the main grocery buyers for that household, living in NSW, Australia. The main outcome measures included parental awareness and attitudes relating to food marketing to children, the perceived role of government versus industry in food marketing regulation and children's food purchasing requests as a result of exposure to food marketing. RESULTS: The majority of parents were concerned about food marketing to children, with the highest level of concern registered for the positioning of food at supermarket checkouts (83% of parents concerned). Parental awareness of certain non-broadcast media food marketing (e.g. print, radio and premium offers) to children was low. The majority of parents (91%) did not trust the industry to protect children from food marketing. Most parents (81%) believed that the government should restrict the use of non-broadcast media marketing of unhealthy food to children. Parents of younger children were more likely to report that their child asked for advertised food products, compared with parents of adolescents (65% and 48% respectively, P < 0.0001). CONCLUSIONS: Reductions in point of sale food promotions would be welcomed by parents. Raising community awareness of the non-broadcast media channels used to market food to children is important as part of building family and policy efforts to limit exposure to this otherwise relatively unregulated media environment.

Recent trends in physical activity in New South Wales. Is the tide of inactivity turning?

OBJECTIVE: To examine recent trends in sufficient physical activity among New South Wales adults aged 16 years and over. METHOD: Data were obtained from New South Wales population health surveys conducted in 1998 and from 2002 to 2005. Analyses examined trends in the proportions of adults achieving sufficient physical activity and trends in different modes of activity. RESULTS: The proportion of adults achieving sufficient physical activity was stable between 1998 (47.6%) and 2002 (46.5%), declined in 2003 (44.7%), increased substantially in 2004 (50.5%), and remained steady in 2005 (51.3%). This increase was evident across different population groups. Adults who did any walking were 18 times more likely to be active than those who did no walking. CONCLUSION: Findings indicate that in recent years physical activity participation has begun to increase, and that this increase occurred across population segments. The increases occurred especially in walking behaviours. IMPLICATIONS: Given the known health benefits of being physically active, continued investment in physical activity promotion policies and programs is necessary to maintain these early gains.

Double standards for community sports: promoting active lifestyles but unhealthy diets.

ISSUE ADDRESSED: Overweight and obesity in Australia is an emerging health concern. Obesity prevention initiatives must consider both physical activity and nutrition to be effective. Community sports venues have the capacity to promote healthy lifestyles through physical activity as well as healthy food choices. METHODS: A telephone survey was conducted on parents of children aged 5-17 years in NSW to determine the nature of food and beverages purchased by children at community sporting venues and to determine parent's perception of the role that government should play in regulating the types of food and beverages sold at these outlets. RESULTS: The majority of canteens at children's sporting venues were considered to sell mostly unhealthy food and beverages (53%). Very few parents reported that canteens sold mostly healthy food and beverages. Parents reported that their child's most frequently purchased food and beverage items at outdoor sports fields were water, chocolate and confectionery, soft drink and sports drinks, and ice cream. At community swimming pools the most frequently purchased items were ice cream, followed by snack foods, including chips, cakes and biscuits. Most parents (63%) agreed that government should restrict the types of food and beverages that can be sold at children's sporting venues. CONCLUSIONS: Children are receiving inconsistent health messages at sporting venues, with healthy lifestyles being promoted through sports participation, but unhealthy dietary choices being provided at sports canteens.

Excisional treatment in women with cervical adenocarcinoma in situ (AIS): a prospective randomised controlled non-inferiority trial to compare AIS persistence/recurrence after loop electrosurgical excision procedure with cold knife cone biopsy: protocol for a pilot study.

INTRODUCTION: Adenocarcinoma in situ (AIS) of the uterine cervix is the precursor to invasive endocervical adenocarcinoma. An excisional biopsy such as a cold knife cone biopsy (CKC) should be performed to exclude invasive adenocarcinoma. Loop electrosurgical excision procedure (LEEP) is an alternative modality to CKC but is controversial in AIS. There is a perception that there is a greater likelihood of incomplete excision of AIS with LEEP because the depth of excised tissue tends to be smaller and the tissue margins may show thermal artefact which can interfere with pathology assessment. In the USA, guidelines recommend that any treatment modality can be used to excise AIS, provided that the specimen remains intact with interpretable margins. However, there are no high-quality studies comparing LEEP with CKC and well-designed prospective studies are needed. If such a study were to show that LEEP was non-inferior to CKC for the outcomes of post-treatment persistence, recurrence and adenocarcinoma, LEEP could be recommended as an appropriate treatment option for AIS in selected patients. This would benefit women because, unlike CKC, LEEP does not require general anaesthesia and may be associated with reduced morbidity. METHODS AND ANALYSIS: The proposed exploratory study is a parallel group trial with an allocation ratio of 2:1 in favour of the intervention (LEEP: CKC). Participants are women aged ≥18 to ≤45 years diagnosed with AIS on cervical screening and/or colposcopically directed biopsy in Australia and New Zealand, who are to receive excisional treatment in a tertiary level centre. ETHICS AND DISSEMINATION: Ethical approval for the study has been granted by the St John of God Healthcare Human Research Ethics Committee (reference number #1137). Results from the study will be presented at conferences and published in a peer-reviewed scientific journal. REGISTRATION: ANZCTR registration number ACTRN12617000132347 https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=372173&isReview=true.

Cytologic findings in stratified mucin-producing intraepithelial lesion of the cervix: A report of 34 cases.

BACKGROUND: Stratified mucin-producing intraepithelial lesion (SMILE) is an uncommon variant of in situ carcinoma of the cervix. This study aimed to identify the cytologic features of SMILE since these have not been well documented previously. METHODS: The study group comprised 34 consecutive cases of SMILE encountered at a single institution in which a corresponding Papanicolaou smear, taken up to 12 months before histologic diagnosis, was available for review. The presence of associated cervical neoplastic lesions including cervical intraepithelial neoplasia (CIN), adenocarcinoma in situ (AIS), and invasive carcinoma was recorded. The linear extent and distribution of the SMILEs was also noted. RESULTS: Most Pap smears had been reported to show possible or definite high-grade CIN although 3 cases reported the presence of a high-grade glandular abnormality. No case had a prospective cytologic diagnosis of SMILE. Histology revealed concurrent CIN and/or AIS in all cases, and 1 specimen (3%) showed invasive adenocarcinoma. Following smear review, 23 of the 31 cases that included endocervical material showed recurrent cytologic features that appeared consistent with SMILE. These included three dimensional cell clusters with nuclear stratification and crowding, mild nuclear atypia, cytoplasmic vacuoles, mitotic figures, and apoptosis. CONCLUSION: SMILE is almost always associated with additional HPV-related neoplastic lesions although only one patient (3%) had invasive carcinoma, a lower rate than recorded in other studies. Consistent cytologic features associated with SMILE were identified but these were relatively subtle. However, increased awareness of these features may permit prospective diagnosis and this could influence patient management.

Physiologic trauma triage criteria in adult trauma patients: are they effective in saving lives by transporting patients to trauma centers?

BACKGROUND: Trauma triage criteria have been in place for many years and were updated in 1999 by the American College of Surgeons. We are unaware of any studies that have directly examined the ability of these criteria to reduce short-term mortality by transporting patients to trauma centers rather than to noncenters. STUDY DESIGN: Retrospective observational cohort study of adult patients meeting physiologic triage criteria who were transported to 9 regional (Level I) trauma centers, 21 area (Level II) trauma centers, and 119 noncenters in New York in 1996 to 1998. For each triage criterion and for one or more of the criteria, odds ratios and their confidence intervals for mortality in regional and area trauma centers versus noncenters and odds ratios and their confidence intervals for mortality in regional centers versus area centers and noncenters were used to measure performance. RESULTS: Patients in regional trauma centers had considerably lower mortality than patients in area trauma centers and noncenters for two individual triage criteria and for patients with one or more triage criteria (odds ratio, 0.75; 95% CI, 0.63-0.90 for one or more criteria). Also, patients with head injuries who were treated in regional centers had notably lower mortality than patients in other hospitals (odds ratio, 0.67; 95% CI, 0.53-0.85). CONCLUSIONS: In New York, regional trauma centers exhibit considerably lower mortality than area trauma centers or noncenters for adult patients meeting specific physiologic triage criteria. It is important that population-based trauma systems with data from centers and noncenters be developed for the purpose of evaluating and redesigning trauma systems.

Characterisation of ivermectin and multi-drug resistance in two field isolates of Teladorsagia circumcincta from Irish sheep flocks.

Ivermectin resistant Teladorsagia circumcincta were isolated from two Irish sheep farms. Parasite naïve lambs were artificially challenged with the isolates in order to test their sensitivity to benzimidazole (BZ), levamisole (LEV) and ivermectin (IVM) by means of a faecal egg count reduction test (FECRT). Both isolates were found to be resistant to all three anthelmintics with reductions of 47% (C.I. 10-68), 92% (C.I. 74-97) and 50% (C.I. 24-68) for the Farm A isolate and of 85% (C.I. 59-94), 89% (C.I. 69-96) and 73% (C.I. 49-86) for the Farm B isolate for BZ, LEV and IVM, respectively. A controlled efficacy test (CET) was undertaken to confirm resistance to IVM and to determine the efficacy of moxidectin (MOX). In agreement with the FECRT, IVM resistance was confirmed for both isolates, with reductions in worm burden of 78% (C.I. 67-85) and 80% (C.I. 45-93) for the Farm A and B isolates respectively. Both isolates were found to be MOX susceptible, with reductions in worm burden of 97% (C.I. 91-99) and 100% for the Farm A and B isolates respectively. Additionally, in vitro tests confirmed the results of the FECRT; results from the larval development assay (LDA) confirmed that both isolates were resistant to BZ and LEV with development observed at the discriminating dose for each drug, while the larval migration inhibition assay (LMIA) confirmed IVM resistance and indicated MOX susceptibility in both isolates. These results represent the first confirmed cases of IVM resistance on Irish sheep farms as well as the first report of multiple anthelmintic resistant gastrointestinal nematodes in Ireland.
