Abstract
Abstract
Background
In spite of advances characterizing the biology of individual breast cancers, current analytics cannot adequately identify truly indolent lesions. As a result many indolent breast cancers and DCIS are over-treated in order to avoid under-treatment of truly life-threatening cancers. Reducing over-treatment for DCIS and small cancers is a current priority for breast cancer management, to optimize both patient care and resource utilization. Intact minimally-invasive excision (percutaneous lumpectomy) with radiofrequency basket capture can eliminate the need for open excision of many atypical ductal hyperplasia (ADH) breast lesions (Whitworth, et al, Ann Surg Oncol, 2011). Percutaneous lumpectomy provides standard margin and lesion analysis of the specimen, accomplishing the same goals as open excision. Here we report results of the IPEX study, a prospective phase 4 trial evaluating the same minimally-invasive strategy when employed to manage small breast cancers and DCIS.
Methods
94 women age 31-86 had minimally-invasive (percutaneous) removal of DCIS or small breast cancers using a 20 mm radiofrequency basket capture technique with stereotactic or ultrasound guidance. Tissue elasticity permitted removal through a small incision (less than 10 mm). A second 20 mm basket capture was used to shave and further evaluate margins. Procedures were conducted with adequate local anesthesia and P.O. sedation in the imaging department. Patient tolerance scores were recorded. Standard radiologic evaluation (specimen and breast) and histologic criteria were applied in all cases. Standard open sentinel node biopsy was offered to patients with invasive breast cancers. All patients provided informed consent for the study.
Results
Final histologic lesion size was 1-20 mm. Of 40 DCIS and 54 invasive lesions, 18 (19%) had positive margins and/or open re-excision, including one patient who had re-excision in spite of negative margins because of inadequate shaved-margin quality (no residual disease on pathology). 58 patients completed APBI (balloon or strut-based brachytherapy) and 16 had whole breast radiation. Of 54 patients with invasive cancers, 34 (age 66-86) had no sentinel node biopsy based on patient preference and low risk features. Patient pain scores averaged 1.9 out of 10 (range 0-7).
Conclusions
Minimally-invasive (percutaneous) lumpectomy provides satisfactory management of DCIS and small breast cancers, accomplishing the same goals as open surgery. The specimen is intact so the pathologist can conduct standard histologic analysis of the lesion, distinguishing DCIS, ADH and invasive cancer. Margin analysis is standard. Compared to open surgery, less tissue can be removed because of small lesion size with more precise targeting and resection. Minimally-invasive (percutaneous) lumpectomy reduces morbidity, distress, discomfort and expense associated with overtreatment of small breast cancers.

Abstract
BACKGROUND Deprivation is associated with an increased risk of invasive Neisseria meningitidis disease, but little is known about the relationship between deprivation and asymptomatic carriage of N. meningitidis. This analysis was conducted to examine the relationship between meningococcal carriage and deprivation. METHODS As part of a rapid meningococcal carriage prevalence study conducted in West Cumbria to investigate an apparent cluster of invasive meningococcal disease, data were collected on lifestyle and social factors, including area-level indicators of socioeconomic status, to identify factors associated with meningococcal carriage. RESULTS In a multivariable log binomial regression model adjusted for age, lower socioeconomic status was significantly associated with higher prevalence of meningococcal carriage. A 1-unit increase in Index of Multiple Deprivation (2010) score was associated with a 1.7% increase in meningococcal carriage prevalence (95% confidence interval 0.3-3.0%). Age was the only significant predictor of carriage of Neisseria lactamica. CONCLUSIONS Living in a deprived area is associated with increased carriage of Group B meningococcus. Deprivation is an important factor to consider in the evaluation of the effectiveness and cost-effectiveness of the introduction of new meningococcal B vaccines and the development and implementation of immunization policies. Further work is required to understand whether deprivation has an effect on meningococcal carriage through other factors such as smoking.

Abstract
BACKGROUND Transnasal endoscopy (TNE) with ultrathin endoscopes has been advocated as an attractive alternative, for diagnostic upper endoscopy. AIM To assess tolerability, acceptability and quality of TNE, in comparison with standard upper endoscopy (SOGD, standard oesophago-gastro-duodenoscopy) under local anaesthetic. METHODS We prospectively recruited 157 patients (83 females/74 males) mean age 57 years. The Fujinon EG530N (5.9 mm) and EG530WR (9.4 mm) endoscopes were used. The endoscopist and all patients completed detailed questionnaires regarding tolerability, acceptance and quality of endoscopy using standard visual analogue scales (VAS). Oxygen saturation (SaO2 ), heart rate (HR) and systolic blood pressure (SBP) were recorded. Quality of biopsies was evaluated. RESULTS Analysis included 161 procedures (TNE:79, SOGD:82) with duodenal intubation achieved in all patients. VAS scores for patient comfort were significantly better in the TNE group (7.3 vs. 5.3 respectively, P < 0.001). Twenty patients with previous experience of standard endoscopy were randomised to TNE and 19 of them (95.5%) preferred the TNE. Gagging was significantly less in the TNE group (0.12 vs. 3.41 respectively, P < 0.001). Cardiovascular stress was significantly less in the TNE group irrespective of the degree of gagging or comfort. TNE biopsies were smaller, but adequate for definitive diagnosis, similarly to standard endoscopy. CONCLUSIONS Transnasal endoscopy is superior to SOGD in terms of comfort and patient acceptance with significantly less cardiovascular stress. TNE can routinely be used as alternative to SOGD under local anaesthetic, for diagnosis and should be preferentially offered in cardiorespiratory compromised patients.

Abstract
While much is known about the influence of HPV type on the progression of pre-invasive cervical lesions, the impact of HPV type on cervical cancer prognosis is less evidenced. Thus, we assessed the impact of HPV type on the survival of women diagnosed with cervical cancer. A total of 370 cases of cervical cancer were assessed. Univariate analysis is presented using Kaplan-Meier survival curves and log-rank statistics and multivariable Cox proportional hazard models were generated using age group, socio-economic deprivation, FIGO stage, differentiation and HPV type. HPV grouping was considered in a number of ways with particular reference to the presence or absence of HPV 16 and/or 18. In the univariate analysis, FIGO, age at diagnosis and treatment were associated with poorer survival (p < 0.0001) as was absence of HPV 16 and/or 18 (p = 0.0460). The 25% mortality time in the non-HPV 16/18 vs. HPV16/18 positive group was 615 days and 1,307 days respectively. An unadjusted Cox PH model based HPV16/18 vs. no HPV 16/18 resulted in a hazard ratio of 0.669 (0.450, 0.995). Adjusting for deprivation, FIGO and age group resulted in a hazard ratio of 0.609 (0.395, 0.941) p = 0.025. These data indicate that cancers associated with HPV 16 and/or 18 do not confer worse survival compared to cancers associated with other types, and may indicate improved survival. Consequently, although HPV vaccine is likely to reduce the incidence of cervical cancer it may not indirectly improve cervical cancer survival by reducing the burden of those cancers caused by HPV16/18.

Abstract
AIMS Human papillomavirus (HPV) testing is more sensitive than cytology for detection of residual/recurrent cervical disease after lesion treatment. Several HPV test comparison studies have been performed within triage and screening populations, but data on their comparative performance in a test of cure context is lacking. This study aims to address this gap. METHODS We compared the technical and clinical performance of Abbott RealTime High risk (HR)-HPV, Genprobe Aptima PV, Hologic Cervista HPV-HR, Qiagen Hybrid Capture 2 and Roche cobas HPV in the Early Implementation phase of a 'test of cure' service within the Scottish Cervical Screening Programme. RESULTS Valid results with all five HPV Tests from 1020 first samples taken ∼6 months post-treatment showed HPV positivity ranging from 17.84% to 26.96%. There was perfect agreement in 74%, and greatest variation between assays was observed in cytologically negative samples. Clinical performance was judged on cumulative incidence of cervical intraepithelial neoplasia 2+ (CIN2+) during follow-up (mean: 13.2 months). There were 23 cases of CIN2+ of which 14 were CIN3+. All assays, including cytology, were 100% sensitive for detection of CIN3+. Of the nine cases of residual CIN2, three assays detected all, one assay missed one and one assay missed two cases. Specificity ranged from 75% to 84% according to assay. CONCLUSIONS All assays were sensitive for detection of CIN2+ at 6 months post-treatment. The range of positivity equated to a 50% increase between assays with the lowest and highest positivity rates. The relevance of HPV positivity in the absence of cytological abnormalities requires longer follow-up to determine whether additional tools for risk stratification are required.

Abstract
Studies characterising the thyroid gland structure of koalas are limited and have not previously been undertaken in South Australian populations. Hence, this study aimed to describe the thyroid gland morphology of koalas from the Mount Lofty region, South Australia. Results showed that thyroid gland morphology was highly variable between individual koalas (n = 36), ranging from that considered typical for healthy mammals, in which small colloid-filled follicles were lined by cuboidal epithelium, to that consistent with colloidal goitre, in which macrofollicles distended with colloid were lined by flattened epithelium. Juvenile koalas more frequently showed typical thyroid gland morphology than adults, with significantly higher thyroid follicle density (P < 0.05) and a higher proportion of follicles lined by cuboidal epithelium compared with flattened epithelium (P < 0.05). Thyroid glands of most adult koalas were characterised by colloidal macrofollicles (P < 0.01), and classified as colloidal goitre. There were no significant differences in thyroid gland morphology based on health status or sex of koalas. These findings suggest that an age-dependent colloidal goitre occurs in adult koalas, which is unlikely to have ill effects and may be associated with the low metabolic rate of this species, or exposure to a dietary goitrogen.

Abstract
Irritable bowel syndrome (IBS) is a common disorder associated with profoundly impaired quality of life and emotional distress. The management of refractory IBS symptoms remains challenging and non-pharmacological therapeutic approaches have been shown to be effective. We compared brief interventions with biofeedback and hypnotherapy in women referred by their GP with refractory IBS symptoms. Patients were randomised to one of two treatment groups, biofeedback or hypnotherapy, delivered as three one-hour sessions over 12 weeks. Symptom assessments were undertaken using validated, self-administered questionnaires. Two of the 128 consecutive IBS patients suitable for the study declined to consider nonpharmacological therapy and 29 patients did not attend beyond the first session. Of the 97 patients randomised into the study, 21 failed to attend the therapy session; 15 of 76 patients who attended for therapy dropped out before week 12 post-therapy. The mean (SD) change in IBS symptom severity score 12 weeks post-treatment in the biofeedback group was -116.8 (99.3) and in the hypnotherapy group -58.0 (101.1), a statistically significant difference between groups (difference=-58.8, 95% confidence interval [CI] for difference [-111.6, -6.1], p=0.029). In 61 patients with refractory IBS, biofeedback and hypnotherapy were equally effective at improving IBS symptom severity scores, total non-gastrointestinal symptom scores and anxiety and depression ratings during 24 weeks follow-up. Biofeedback may prove to be the more cost-effective option as it requires less expertise.

Abstract
Emerging data indicate that all-oral antiviral treatments for chronic hepatitis C virus (HCV) will become a reality in the near future. In replacing interferon-based therapies, all-oral regimens are expected to be more tolerable, more effective, shorter in duration and simpler to administer. Coinciding with new treatment options are novel methodologies for disease screening and staging, which create the possibility of more timely care and treatment. Assessments of histologic damage typically are performed using liver biopsy, yet noninvasive assessments of histologic damage have become the norm in some European countries and are becoming more widespread in the United States. Also in place are new Centers for Disease Control and Prevention (CDC) initiatives to simplify testing, improve provider and patient awareness and expand recommendations for HCV screening beyond risk-based strategies. Issued in 2012, the CDC recommendations aim to increase HCV testing among those with the greatest HCV burden in the United States by recommending one-time testing for all persons born during 1945-1965. In 2013, the United States Preventive Services Task Force adopted similar recommendations for risk-based and birth-cohort-based testing. Taken together, the developments in screening, diagnosis and treatment will likely increase demand for therapy and stimulate a shift in delivery of care related to chronic HCV, with increased involvement of primary care and infectious disease specialists. Yet even in this new era of therapy, barriers to curing patients of HCV will exist. Overcoming such barriers will require novel, integrative strategies and investment of resources at local, regional and national levels.

Abstract
BACKGROUND Venous thromboembolism is a common, potentially avoidable cause of death and morbidity in patients in hospital, including those with stroke. In surgical patients, intermittent pneumatic compression (IPC) reduces the risk of deep vein thrombosis (DVT), but no reliable evidence exists about its effectiveness in patients who have had a stroke. We assessed the effectiveness of IPC to reduce the risk of DVT in patients who have had a stroke. METHODS The CLOTS 3 trial is a multicentre parallel group randomised trial assessing IPC in immobile patients (ie, who cannot walk to the toilet without the help of another person) with acute stroke. We enrolled patients from day 0 to day 3 of admission and allocated them via a central randomisation system (ratio 1:1) to receive either IPC or no IPC. A technician who was masked to treatment allocation did a compression duplex ultrasound (CDU) of both legs at 7-10 days and, wherever practical, at 25-30 days after enrolment. Caregivers and patients were not masked to treatment assignment. Patients were followed up for 6 months to determine survival and later symptomatic venous thromboembolism. The primary outcome was a DVT in the proximal veins detected on a screening CDU or any symptomatic DVT in the proximal veins, confirmed on imaging, within 30 days of randomisation. Patients were analysed according to their treatment allocation. TRIAL REGISTRATION ISRCTN93529999. FINDINGS Between Dec 8, 2008, and Sept 6, 2012, 2876 patients were enrolled in 94 centres in the UK. The included patients were broadly representative of immobile stroke patients admitted to hospital and had a median age of 76 years (IQR 67-84). The primary outcome occurred in 122 (8·5%) of 1438 patients allocated IPC and 174 (12·1%) of 1438 patients allocated no IPC; an absolute reduction in risk of 3·6% (95% CI 1·4-5·8). Excluding the 323 patients who died before any primary outcome and 41 without any screening CDU, the adjusted OR for the comparison of 122 of 1267 patients vs 174 of 1245 patients was 0·65 (95% CI 0·51-0·84; p=0·001). Deaths in the treatment period occurred in 156 (11%) patients allocated IPC and 189 (13%) patients allocated no IPC died within the 30 days of treatment period (p=0·057); skin breaks on the legs were reported in 44 (3%) patients allocated IPC and in 20 (1%) patients allocated no IPC (p=0·002); falls with injury were reported in 33 (2%) patients in the IPC group and in 24 (2%) patients in the no-IPC group (p=0·221). INTERPRETATION IPC is an effective method of reducing the risk of DVT and possibly improving survival in a wide variety of patients who are immobile after stroke.

Abstract
OBJECTIVE Cytology laboratories routinely treat cervical liquid-based cytology (LBC) specimens that are heavily contaminated with blood with glacial acetic acid (GAA) in order to lyse red blood cells and facilitate assessment. However, the impact on downstream human papillomavirus (HPV) detection is not well understood. This study examines the effect of GAA pre-treatment of ThinPrep(®) Preservcyt(®) specimens on the molecular detection of HPV. METHODS A panel of 150 routinely collected cervical LBC specimens was tested with two commercial HPV tests, the Abbott RealTime High Risk HPV test (rtHPV) and the Qiagen Hybrid Capture 2 High Risk HPV DNA test (HC2), as aliquots before and after GAA treatment. Statistical analysis was performed using McNemars test and Bland and Altman plots. RESULTS Agreement between the results of the rtHPV test on GAA-untreated and GAA-treated specimens was 95.7%, with no evidence of a significant difference in the distribution of the discrepant results (P = 0.414). HC2 test agreement on GAA-untreated and GAA-treated specimens was 91% at a cut-off of 1 relative light unit index (RLUI) and 92% at a cut-off of 2 RLUI. There was no evidence of a difference in the distribution of discordant results at a cut-off of 1 (P = 0.405) and 2 RLUI (P = 0.564). CONCLUSIONS GAA pre-treatment of cervical ThinPrep Preservcyt LBC specimens had little effect on the two commercial HPV tests used in this study. The impact of GAA treatment on HPV testing should, however, be validated for all HPV tests and all LBC collection media used in each particular diagnostic setting.

Abstract
INTRODUCTION Parastomal herniation occurs in 30–50% of colostomy formations. The aim of this study was to radiologically evaluate the mechanical defects at stoma sites in patients who had previously undergone a permanent colostomy with or without mesh at the index operation for colorectal cancer. METHODS A study was performed of all colorectal cancer patients (n=41) having an end colostomy between 2002 and 2010, with or without Prolene® mesh plication, with blinded evaluation of the annual follow-up staging computed tomography (CT) for stomal characteristics. The presence of parastomal hernias, volume, dimensions, grade of the parastomal hernia and abdominal wall defect size were measured by two independent radiologists, and compared with demographic and operative variables. RESULTS In those patients with radiological evidence of a parastomal hernia, Prolene® mesh plication significantly reduced the incidence of bowel containing parastomal hernias at one year following the procedure (p<0.05) and also reduced the diameter of the abdominal wall defect (p=0.006). CONCLUSIONS Prophylactic mesh placement at the time of the index procedure reduces the diameter of abdominal wall aperture and the incidence of parastomal hernias containing bowel. Future studies should use both objective radiological as well as clinical endpoints when assessing parastomal hernia development with and without prophylactic mesh.

Abstract
INTRODUCTION Reducing exogenously administered opioids in the post-operative period is associated with early return of bowel function and decreased post-operative complication rates. We evaluated the effectiveness of a surgeon-delivered open transversus abdominis plane (TAP) block as a method to reduce post-operative opioid requirements, sedation and inpatient stay. METHODS The patient cohort was identified from those who had undergone a right hemicolectomy for colonic cancer. Patients received either an open TAP block and post-operative patient controlled anaesthesia (PCA) (n=20) or were part of a control group who received subcutaneous local anaesthetic infiltration and PCA (n=16). RESULTS PCA morphine use was reduced within the first 24 hours post-operatively in the TAP block group compared with controls (42.1mg vs 72.3mg, p=0.002). Sedation was also reduced significantly in the early post-operative period (p<0.04). There was a non-significant trend towards reduced length of stay in the intervention group (8.2 vs 8.73 days). There were no recorded complications attributable to the open TAP block. CONCLUSIONS Open TAP blocks are safe and reduce post-operative opioid requirements and sedation after right hemicolectomies. They should be considered as part of a multimodal enhanced recovery approach to patients undergoing abdominal surgery via a transverse incision.
