Abstract
Background The use of image guidance systems has gained widespread acceptance as an adjunctive tool for endoscopic sinus surgery. However, the accessibility and usage of this technology is variable across hospitals in Canada.
Study objective The aim of this study is to investigate the availability, usage, and related issues surrounding the use of image guidance systems in endoscopic sinus surgery across Canadian otolaryngology practice settings. Methods An online survey was electronically distributed to practicing otolaryngologists across Canada. The survey contained 27 questions pertaining to the availability, usage, barriers and overall experience of image guidance systems. Results The survey was electronically sent to a total of 654 Canadian otolaryngologists of which 158 responded (response rate 24.2%). Image guidance was available to 56.3% of respondents. Of the respondents without access to IGS, 85.5% indicated they would use it if it was available. Financial (capital cost) was identified as the most important barrier in obtaining IGS by 76.3% of respondents. Conclusion Over half of Canadian otolaryngologists have access to IGS with over 85% of those without access interested in using it if it was made available. A multitude of different factors contribute to this disparity. We hope that the results of this study will help support Canadian otolaryngologists to access IGS. Graphical Abstract ![]()

Abstract
Aims To describe readmissions of hospitalised patients with COVID-19, define predictors of readmission and explore the long term outcomes using the SF-12 score compared to patients who were not readmitted and those not hospitalised. Methods A single centre retrospective in North Inner-City Dublin. Recruitment was done through a COVID follow up clinic. Predictors of readmission and SF-12 scores at two timepoints post follow up at median 3 months and 12 months. Results Seventy (45%) participants were admitted, with a median age of 49.5 years (IQR 41.3-56.9), 36(51%) of whom were female. Unscheduled readmissions at ≤30 days in COVID-19 patients were 9(12.9%) and length of stay was four days (IQR 2-5). Readmissions were due to ongoing symptoms(n=9(64.3%)) or new complications(n=5(35.7%)). Mechanical ventilation and having symptoms of nausea and vomiting on index admission were predictive of readmission. (p=0.002). SF-12 scores at one year of readmitted patients were not different to patients who were never admitted at median one year follow up, p=.089. Conclusions Most readmissions were of short duration. Early follow up of patients post MV or who had nausea and vomiting on index admission should be prioritised. Wellbeing of readmitted patients was not different to those never hospitalised, at one year.

Abstract
BACKGROUND Few studies to date have explored HRQoL in long COVID patients. METHODS The Anticipate Study is a prospective single centre observational cohort study. Hospitalised and non-hospitalised patients were seen at a dedicated post-Covid clinic at a 2-4 month (Timepoint 1) and 7-14 month follow up (Timepoint 2). The main objectives of this study are to assess the longitudinal impact of COVID-19 in patients using the 12-item Short Form Survey (SF-12) score, a Health Related Quality of Life tool, also to identify predictors of developing Post COVID-19 Syndrome (PoCS). Also, to describe symptomatology and identify predictors of PoCS at 1 year. RESULTS 155 patients were enrolled, 105(68%) were female aged 43.3 (31-52) years. In total 149(96%) and 94(61%) completed follow up at median 96(76-118) days and 364 (303-398) days. The overall cohort had significantly reduced Physical Composite Score (PCS) of the SF-12 (45.39(10.58) vs 50(10), p=.02). Participants with PoCS had significantly lower scores than those without symptoms at 1 year follow up (37.2(10.4) v 46.1(10.9) p <0.001), and scores for these patients did not improve over the two Timepoints (PCS 34.95(10.5) - 37.2(10.4), p=.22). Fatigue was the most common symptom. Those with five or more symptoms at initial diagnosis had lower PCS and MCS scores at 1 year. Predictors of PoCS at 1-year were lower PCS, and higher baseline heart rate (HR) at clinic review median 3 months after COVID-19. CONCLUSION PoCS patients have lower PCS scores during follow-up which did not significantly improve up to a 1-year follow up. Lower PCS scores and higher resting HR can be used in the weeks after COVID-19 can help predict those at risk of PoCS.

Abstract
Background: Ongoing mental health problems following COVID-19 infection warrant greater examination. This study aimed to investigate psychiatric symptoms and problematic alcohol use among Long COVID patients. Methods: The study was conducted at the Mater Misericordiae University Hospital’s post-COVID-19 follow-up clinic in Dublin, Ireland. A prospective cohort study design was used encompassing assessment of patients’ outcomes at 2-4 months following an initial clinic visit (Time 1), and 7–14-month follow-up (Time 2). Outcomes regarding participants’ demographics, acute COVID-19 healthcare use, mental health, and alcohol use were examined. Results: The baseline sample’s (n = 153) median age = 43.5yrs (females = 105 (68.6%)). Sixty-seven of 153 patients (43.8%) were admitted to hospital with COVID-19, 9/67 (13.4%) were admitted to ICU, and 17/67 (25.4%) were readmitted to hospital following an initial COVID-19 stay. Sixteen of 67 (23.9%) visited a GP within seven days of hospital discharge, and 26/67 (38.8%) did so within 30 days. Seventeen of 153 participants (11.1%) had a pre-existing affective disorder. The prevalence of clinical range depression, anxiety, and PTSD scores at Time 1 and Time 2 (n = 93) ranged from 12.9% (Time 1 anxiety) to 22.6% (Time 1 PTSD). No statistically significant differences were observed between Time 1 and Time 2 depression, anxiety, and PTSD scores. Problematic alcohol use was common at Time 1 (45.5%) and significantly more so at Time 2 (71.8%). Clinical range depression, anxiety, and PTSD scores were significantly more frequent among acute COVID-19 hospital admission and GP attendance (30 days) participants, as well as among participants with lengthy ICU stays, and those with a previous affective disorder diagnosis. Conclusions: Ongoing psychiatric symptoms and problematic alcohol use in Long COVID populations are a concern and these issues may be more common among individuals with severe acute COVID-19 infection and /or pre-existing mental illness.

Abstract
BACKGROUND In Irish prisons, there is a high proportion of people who inject drugs (PWID; 26%) and a high prevalence of HCV (16%), making prison a high priority setting for HCV testing and treatment. We evaluate the cost-effectiveness of a mass HCV screening intervention in Mountjoy Prison, Dublin, compared to the standard-of-care of intermittent screening on committal. METHODS Primary cost data was collected from the intervention using an overall provider perspective. Standard-of-care (SOC) costs were estimated through interview. All costs were inflated to 2020 Euros. An HCV transmission and disease progression model among incarcerated and community PWID and ex-injectors was calibrated to the Dublin HCV epidemic, allowing inclusion of population-level health benefits. The model used intervention data, suggesting 419 individuals were screened, 50 HCV infections diagnosed and 32 individuals initiated treatment, to project the resulting costs and health benefits (quality adjusted life years or QALYs) over 50 years with 5% discounting. The incremental cost effectiveness ratio (ICER), cost per QALY gained, was estimated for the screening intervention compared to the standard-of-care. Probabilistic sensitivity analyses (PSA) determined the probability that the intervention was cost-effective compared to a willingness-to-pay threshold of €30,000/QALY as used in Ireland. The ICER for 1- or 3-yearly mass screening in all Dublin prisons was also calculated. RESULTS The total direct costs of the intervention (not including treatment drug costs) was €82,392, with most costs being due to staff (43%) and overhead or management costs (38%). Despite having little epidemiological impact due to the small numbers treated, over 50 years the incremental cost of the intervention was €36,592 and 3.8 QALYs were gained, giving a mean ICER of €9,552/QALY. The majority (84%) of PSA runs were below the willingness-to-pay threshold. Yearly mass screening had an ICER of €2,729/QALY compared to SOC and gave a higher net monetary benefit (€7,393,382) than screening every 3 years (€6,252,816). CONCLUSION Prison mass screening could be a cost-effective initiative for increasing testing and treatment of HCV in Ireland.

Abstract
BACKGROUND Prisoners are recognised as a high-risk population and prisons as high-risk locations for the transmission of hepatitis c virus (HCV) infection. Injecting drug use (IDU) is the main driver of HCV infection in prisoners and harm reduction services are often suboptimal in prison settings. HCV prevalence and incident data in prisoners is incomplete which impacts the public health opportunity that incarceration provides in identifying, treating and preventing HCV infection. The aim of this study is to identify new HCV infection and associated risk factors in an Irish male prison. METHODS We conducted a follow up (18-month) cohort study on prisoners who had previously tested negative, self-cleared or had been successfully treated for HCV infection. We conducted the study in a male medium security prison located in Dublin Ireland (Mountjoy Prison) using HCV serology, a review of medical records and a researcher-administered questionnaire. RESULTS 99 prisoners with a mean age of 33.2 yrs. participated in the study and 82(82.8%) completed a research-administered questionnaire. Over half (51%) had a history of drug use from a young age (14.8 yrs.), 49.9% a history of heroin use and 39% a history of IDU. The prevalence of HIV and hepatitis B virus core antibody was 3% and HCV antibody was 22.2%. No new HCV infections were identified in those who had never been infected (n = 77), had self-cleared (n = 9) or achieved sustained virological response (n = 12). Small numbers of prisoners continued to engage in risk-behaviour including, IDU both in the prison (n = 2) and the community (n = 3), sharing syringes (n = 1) and drug taking paraphernalia (n = 6) and receiving non-sterile tattoos (n = 3). CONCLUSION Despite the high numbers of Irish prisoners with a history of IDU and HCV infection, new HCV infection is low or non-existent in this population. Small numbers of prisoners continue to engage in risk behaviour and larger studies are required to further understand HCV transmission in this cohort in an Irish and international context.

Abstract
BACKGROUND A high proportion of hospitalized patients with COVID-19 receive antibiotics despite evidence to show low levels of true bacterial coinfection. METHODS A retrospective cohort study examining antibiotic prescribing patterns of 300 patients sequentially diagnosed with COVID-19. Patients were grouped into 3 sub-cohorts: Group 1 received no antibiotics, Group 2 received antibiotics for microbiologically confirmed infections and Group 3 was empirically treated with antibiotics for pneumonia. The primary aim was to identify factors that influenced prescription and continuation of antibiotics in Group 3. Secondary aims were to examine differences in outcomes between groups. RESULTS In total, 292 patients were included (63 Group 1, 35 Group 2, 194 Group 3), median age was 60 years (IQR 44-76) and the majority were ethnically Irish (62%). The median duration of antibiotics was 7 days (IQR 5-10). In Group 3, factors associated with prescription IV antibiotics on admission were raised C-reactive protein (CRP) (P = 0.024), increased age (P = 0.023), higher quick SOFA (P = 0.016) score and fever >37.5 °C (P = 0.011). Factors associated with duration of antibiotic course were duration of hypoxia (P < 0.001) and maximum respiratory support requirement (P = 0.013). Twenty-one patients in Group 3 had one or more antibiotic escalation events, most (n = 139) had no escalation or de-escalation of therapy. CONCLUSIONS Duration of hypoxia and need for respiratory support may have acted as surrogate measures of improvement where usual response measures (CRP, neutrophilia, culture clearance) were absent. Continuous review of antibiotic prescriptions should be at the forefront of clinical management of hospitalized patients with COVID-19.

Abstract
Background: While the COVID-19 pandemic is currently impacting on health and social care in Ireland, this impact is most marked in metropolitan Dublin. This is especially the case for the Mater Misericordiae University Hospital (MMUH) in Dublin's North Inner, which is situated in an area where local socially deprived communities are at high risk of infection and of experiencing adverse outcomes. Aims: To determine baseline characteristics and longer-term care outcomes of COVID-19 patients presenting to / attending the Infectious Diseases Department at MMUH, including the virtual clinic. Methods: Retrospective study: we will retrospectively examine clinical records and extract anonymised data on patient demographics, baseline morbidity and outcomes. Prospective study: we will prospectively examine healthcare outcomes among patients who consent to follow up at two time points (three months, and six months to 12 months after discharge/onset of disease). Two patient groups will be assessed for morbid complications: those hospitalised with COVID infection and those followed-up remotely with confirmed COVID infection. Deliverables: The project will involve collaboration with Ireland's Health Service Executive (HSE) Clinical Programmes and Ireland East Hospital Group to inform health service policies that will attenuate the adverse impacts of the COVID pandemic on population health. This research protocol will evaluate morbid complications of COVID depending on the severity of the disease.

Abstract
Background: Ireland has experienced an outbreak of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). While several cohorts from China have been described, there is little data describing the epidemiological and clinical characteristics of Irish patients with COVID-19. To improve our understanding of this infection we performed a retrospective review of patient data to examine the clinical characteristics of patients admitted for COVID-19 hospital treatment. Methods: Demographic, clinical and laboratory data on the first 100 patients admitted to Mater Misericordiae University Hospital for in-patient COVID-19 treatment after onset of the outbreak in March 2020 was extracted from patient records. Results: The median age was 45 years (interquartile range [IQR] =34-64 years), 58% were male, and 63% were Irish nationals. Patients had symptoms for a median of five days before diagnosis (IQR=2.5-7 days), most commonly cough (72%), fever (65%), dyspnoea (37%), fatigue (28%), myalgia (27%) and headache (24%). Of all cases, 54 had at least one pre-existing chronic illness (most commonly hypertension, diabetes mellitus or asthma). At initial assessment, the most common abnormal findings were: C-reactive protein >7.0mg/L (74%), ferritin >247μg/L (women) or >275μg/L (men) (62%), D-dimer >0.5μg/dL (62%), chest imaging (59%), NEWS Score (modified) of ≥3 (55%) and heart rate >90/min (51%). Supplemental oxygen was required by 27 patients, of which 17 were admitted to the intensive care unit - 14 requiring ventilation. Antiviral therapy was administered to 40 patients (most commonly hydroxychloroquine or lopinavir/ritonavir). Four died, 17 were admitted to intensive care, and 74 were discharged home, with nine days the median hospital stay (IQR=6-11). Conclusion: Our findings reinforce the consensus of COVID-19 as an acute life-threatening disease and highlights the importance of laboratory (ferritin, C-reactive protein, D-dimer) and radiological parameters, in addition to clinical parameters. Further cohort studies followed longitudinally are a priority.

Abstract
Background: It is accepted that COVID-19 will have considerable long-term consequences, especially on people’s mental and physical health and wellbeing. Although the impacts on local communities have been immense, there remains little data on long term outcomes among patients with COVID-19 who were managed in general practice and primary care. This study seeks to address this knowledge gap by examining how the COVID-19 pandemic has impacted the medium and long-term health and wellbeing of patients attending general practice, especially their mental health and wellbeing. Methods: The study will be conducted at 12 general practices in the catchment area of the Mater Misericordiae University Hospital, i.e. the North Dublin area, an area which has experienced an especially high COVID-19 incidence. Practices will be recruited from the professional networks of the research team. A member of the general practice team will be asked to identify patients of the practice who attended the practice after 16/3/20 with a confirmed or presumptive diagnosis of COVID-19 infection. Potential participants will be provided with information on the study by the clinical team. Data will be collected on those patients who consent to participate by means of an interviewer-administered questionnaire and review of clinical records. Data will be collected on health (especially mental health) and wellbeing, quality of life, health behaviours, health service utilisation, and wider impacts of COVID-19 at recruitment and at two follow up time points (6, 12 months). Deliverables: The project involves collaboration with Ireland’s Health Service Executive, Ireland East Hospital Group, and the Mater Misericordiae University Hospital, Dublin. The study is funded by the Health Research Board. Findings will inform health policies that attenuate the adverse impacts of COVID-19 on population mental health and health generally.

Abstract
Hepatitis C virus (HCV) remains a major cause of morbidity and death worldwide, with prevalence highest among people who inject drugs (PWID), homeless populations and prisoners. The World Health Organization has published targets to be achieved by 2030 as part of its global health sector strategy to eliminate viral hepatitis. Recent innovations in testing and treatment of HCV mean such goals are achievable with effective infrastructure, political will and funding. 'HepCare Europe' was a 3-year, EU-funded project involving four member states. It sought to develop, implement and evaluate interventions to improve HCV outcomes through multiple-level interventions, running between 2016 and 2019. This paper aims to summarize the methods and present the aggregate cascade of care figures for the Irish components of HepCare. 'HepCare Ireland' contained five integrated work packages: HepCheck, HepLink, HepFriend, HepEd and HepCost. Interventions included intensified screening, community-based assessment, linkage to specialist care, peer training and support, multidisciplinary educational resources and cost-effectiveness analysis. A total of 812 participants were recruited across the three clinical work packages in Ireland. Two hundred and fifty-seven (31.7%) of the tested participants had an HCV antibody-positive result, with 162 (63.0%) testing positive for HCV RNA. At the time of writing (6th of November 2019), 57 (54.8%) of participants put on treatment had achieved SVR12, with 44 (42.3%) still undergoing treatment. In HepCheck, HepLink. HepEd and HepFriend, we demonstrate a series of interventions to improve Irish HCV outcomes. Our findings highlight the benefits of multilevel interventions in HCV care.

Abstract
Background It is increasingly being recognized that the elimination of HCV requires a multidisciplinary approach and effective cooperation between primary and secondary care. Objectives As part of a project (HepCare Europe) to integrate primary and secondary care for patients at risk of or infected with HCV, we developed a multidisciplinary educational Masterclass series for healthcare professionals (HCPs) working in primary care in Dublin and Bucharest. This article aims to describe and evaluate the series and examine how this model might be implemented into practice. Methods GPs and other HCPs working in primary care, addiction treatment services and NGOs were invited to eight 1 day symposia (HCV Masterclass series), examining the burden and management of HCV in key populations. Peer-support sessions were also conducted, to give people affected by HCV and community-based organizations working with those directly affected, an update on the latest developments in HCV treatment. Results One hundred percent of participants ‘strongly agreed’ or ‘agreed’ that the Masterclass helped them to appreciate the role of integrated services in ‘the management of patients with HCV’. One hundred percent of participants indicated the importance of a ‘designated nurse to liaise with hospital services’. An improvement of knowledge regarding HCV management of patients with high-risk behaviour was registered at the end of the course. Conclusions Integrated approaches to healthcare and improving the knowledge of HCPs and patients of the latest developments in HCV treatment are very important strategies that can enhance the HCV care pathway and treatment outcomes.

Abstract
Objectives Hepatitis C is one of the main causes of chronic liver diseases worldwide. One of the major barriers to effecting EU- and WHO-mandated HCV elimination by 2030 is underdiagnosis. Community-based screening strategies have been identified as important components of HCV models of care. HepCheck Europe is a large-scale intensified screening initiative aimed at enhancing identification of HCV infection among vulnerable populations and linkage to care. Methods Research teams across four European countries were engaged in the study and rolled out screening to high-risk populations in community addiction, homeless and prison services. Screening was offered to 2822 individuals and included a self-administered questionnaire, HCV antibody and RNA testing, liver fibrosis assessment and referral to specialist services. Results There was a 74% (n=2079) uptake of screening. The majority (85.8%, n=1783) were male. In total 44.6% (n=927) of the sample reported ever injecting drugs, 38.4% (n=799) reported ever being homeless and 27.9% (n=581) were prisoners. In total 397 (19%) active HCV infections were identified and 136 (7% of total sample and 34% of identified active infections) were new cases. Of those identified with active HCV infection, 80% were linked to care, which included liver fibrosis assessment and referral to specialist services. Conclusions HepCheck’s screening and linkage to care is a clear strategy for reaching high-risk populations, including those at highest risk of transmission who are not accessing any type of care in the community. Elimination of HCV in the EU will only be achieved by such innovative, patient-centred approaches.

Abstract
IntroductionData on chronic hepatitis C (HCV) infection prevalence in European prisons are incomplete and impact the public health opportunity that incarceration provides.AimsWe aimed to estimate the seroprevalence of untreated chronic HCV infection and to identify associated risk factors in an Irish male prison.MethodsWe conducted a cross-sectional study involving a researcher-administered questionnaire, review of medical records and HCV serology.ResultsOf 422 prisoners (78.0% of the study population) who participated in the study, 298 (70.6%) completed the questionnaire and 403 (95.5%) were tested for HCV antibodies. Of those tested, 92 (22.8%) were HCV antibody-positive, and of those, 53 (57.6%) were HCV RNA-positive, 23 (25.0%) had spontaneous clearance, 16 (17.4%) had a sustained viral response, 10 (11.0%) were co-infected with HIV and six (6.0%) with HBV. The untreated chronic HCV seroprevalence estimate was 13.1% and the seroprevalence of HCV among prisoners with a history of injecting drug use (IDU) was 79.7%. Risk factors significantly associated with past HCV infection were IDU (p < 0.0001), having received a prison tattoo (p < 0.0001) or a non-sterile community tattoo (p < 0.0001), sharing needles and other drug-taking paraphernalia (p < 0.0001). Small numbers of prisoners had a history of sharing razors (n=10; 3.4%) and toothbrushes (n=3; 1.0%) while incarcerated. On multivariable analysis, history of receiving a non-sterile community tattoo was the only significant risk factor associated with HCV acquisition (after IDU was removed from the model) (p = 0.005, β = 0.468).ConclusionThe level of untreated chronic HCV infection in Irish prisons is high, with IDU the main associated risk.

Abstract
BACKGROUND Hepatitis C infection is a major public health concern globally. In Ireland, like other European countries, people who use drugs (PWUD) and prisoners carry a larger HCV disease burden than the general population. Recent advances in HCV management have made HCV elimination across Europe a realistic goal. Engaging these two marginalised and underserved populations remains a challenge. The aim of this review was to map key findings and identify gaps in the literature (published and unpublished) on HCV infection in Irish PWUD and prisoners. METHODS A scoping review guided by the methodological framework set out by Levac and colleagues (based on previous work by Arksey & O'Malley). RESULTS A total of 58 studies were identified and divided into the following categories; Epidemiology, Guidelines and Policy, Treatment Outcomes, HCV-related Health Issues and qualitative research reporting on Patients' and Health Providers' Experiences. This review identified significantly higher rates of HCV infection among Irish prisoners and PWUD than the general population. There are high levels of undiagnosed and untreated HCV infection in both groups. There is poor engagement by Irish PWUD with HCV services and barriers have been identified. Prison hepatology nurse services have a positive impact on treatment uptake and outcomes. Identified gaps in the literature include; lack of accurate epidemiological data on incident infection, untreated chronic HCV infection particularly in PWUD living outside Dublin and those not engaged with OST. CONCLUSION Ireland like other European countries has high levels of undiagnosed and untreated HCV infection. Collecting, synthesising and identifying gaps in the available literature is timely and will inform national HCV screening, treatment and prevention strategies.

Abstract
BACKGROUND Hepatitis C Virus (HCV) infection is endemic in prison populations, and HCV management in prisons is suboptimal. Incarceration is a public health opportunity to target this cohort. Community peer support increases HCV screening and treatment uptake. Prison peer workers have the potential to support the engagement of prisoners with health services and reduce stigma. This study's primary aim is to evaluate peer-supported screening as a model of active HCV case finding with a secondary aim to describe the HCV cascade among those infected including linkage to care and treatment outcomes. METHODS An observational study was conducted in a medium-security Irish male prison housing 538 inmates, using a risk-based questionnaire, medical records, peer-supported screening, laboratory-based HCV serology tests and mobile elastography. RESULTS A prison peer-supported screening initiative engaged large numbers of prisoners in HCV screening (n = 419). The mean age of participants was 32.8 years, 92% were Irish and 33% had a history of injecting drug use. Multiple risk factors for HCV acquisition were identified including needle sharing (16%). On serological testing, 87 (21%) were HCV Ab +ve and 50 (12%) were HCV RNA +ve of whom 80% were fibroscaned (25% showing evidence of liver disease). Eighty-six percent of those with active infection were linked with HCV care, with 33% undergoing or completing treatment. There was a high concordance with HCV disclosure at committal and serological testing (96% for HCV Ab +ve and 89% for HCV Ab -ve). CONCLUSION Peer-supported screening is an effective active HCV case-finding model to find and link prisoners with untreated active HCV infection to HCV care.

Abstract
BACKGROUND Hepatitis C virus (HCV) is one of the main causes of chronic liver disease worldwide. Prevalence of HCV in homeless populations ranges from 3.9 to 36.2%. The HepCheck study sought to investigate and establish the characterisation of HCV burden among individuals who attended an intensified screening programme for HCV in homeless services in Dublin, Ireland. METHODS The HepCheck study was conducted as part of a larger European wide initiative called HepCare Europe. The study consisted of three phases; 1) all subjects completed a short survey and were offered a rapid oral HCV test; 2) a convenience sample of HCV positive participants from phase 1 were selected to complete a survey on health and social risk factors and 3) subjects were tracked along the referral pathway to identify whether they were referred to a specialist clinic, attended the specialist clinic, were assessed for cirrhosis by transient elastography (Fibroscan) and were treated for HCV. RESULTS Five hundred ninety-seven individuals were offered HCV screening, 73% were male and 63% reported having had a previous HCV screening. We screened 538 (90%) of those offered screening, with 37% testing positive. Among those who tested positive, 112 (56%) were 'new positives' and 44% were 'known positives'. Undiagnosed HCV was prevalent in 19% of the study sample. Active past 30-day drug use was common, along with attendance for drug treatment. Unstable accommodation was the most common barrier to attending specialist appointments and accessing treatment. Depression and anxiety, dental problems and respiratory conditions were common reported health problems. Forty-six subjects were referred to specialised services and two subjects completed HCV treatment. CONCLUSIONS This study demonstrates that the current hospital-based model of care is inadequate in addressing the specific needs of a homeless population and emphasises the need for a community-based treatment approach. Findings are intended to inform HepCare Europe in their development of a community-based model of care in order to engage with homeless individuals with multiple co-morbidities including substance abuse, who are affected by or infected with HCV.

Abstract
The key learning points of Surgical Grand Rounds (SGR) are often not accessible at times of exam revision for students. We sought to use Twitter as an online teaching repository. A SGR Twitter profile was created. 23 SGR presentations were made accessible on Twitter over a 3 month period. 93 students were invited to complete a questionnaire assessing usage of the repository. 84 (90%) in total responded, of these, 25 (80.6%) felt that the online provision of SGR through twitter was "useful". The majority (71%) felt that the online content was easily accessible. The novel use of social media is a useful adjunctive educational tool in accessing an online repository of SGR presentations.

Abstract
Abstract
Background: Mutations in the BRCA 1/2 genes predispose women to increased risk of breast and ovarian cancer. Prophylactic mastectomy (PM) reduces the risk of breast cancer by approximately 90% while prophylactic salpingo-oophorectomy (PSO) reduces the risk of both breast and ovarian cancer. Yet, there is a paucity of data to determine if mutation carriers avail themselves of these risk reducing surgeries in the community setting.Purpose: This study evaluates if particular socioeconomic factors influence BRCA 1/2 mutation carriers to elect risk reduction surgery (RRS), either PM or PSO or both.Method: Of 129 BRCA1/2 positive patients identified by a community-based cancer genetics program outside Philadelphia from 1998 to 2008, 44 were excluded due to personal history of ovarian cancer, loss of follow-up, male gender, or deceased status. The 85 remaining patients were asked to complete a questionnaire addressing: age at diagnosis, ethnicity, religion, parity, education level, marital status, occupation, number of first degree relatives with breast or ovarian cancer, personal history of breast cancer, and use of oral contraceptives, tobacco, and alcohol. A chart review was performed on all responders.Results: Forty-nine patients (58%) completed the questionnaire. Of these, 68% (34/49) had RRS. Of those who did not have RRS, 63% (10/15) stated they definitely plan for RRS in the future. More than half of the women planning RRS in the future (6/10) were younger than 30 years old. Therefore, of all responders, 90% (44/49) stated they had or definitely plan to have RRS. The mean age of women with RRS versus those without was 43.9 and 35.6 years, respectively (p=.0102). Women age 40-64 had the highest rate of RRS (26/34; 84%; p=0.004). Most women (88%) with RRS had children (30/34; p=0.0493). Sixty-five percent (32/49) of women responders were college graduates; 24% were high school graduates (12/49). Of women who had RRS, 68% were college graduates. College graduates age > 40 were the group most likely to have RRS (17/18; 94%; p= .00029). Only 63% of high school graduates age > 40 (5/8; p=1.0) had RRS. Eight-five percent (11/13) of Ashkenazi Jewish women had RRS versus 67% (18/27) of non-Jewish Caucasian women. This was not statistically significant (p=0.2925). There was also no statistical difference for women choosing RRS with respect to occupation, birth control pill use, history of breast cancer, or family history of breast or ovarian cancer. Only 3/49 smoked cigarettes (>more than 1 pack per week) and none drank alcohol (>1 drink/day).Discussion: Women who presented to this community based genetics program had a high rate of RRS, were likely to be college educated, non-smokers, and non-drinkers. Age older than 40, completion of child bearing, and attainment of a college degree were the most significant factors associated with BRCA 1/2 mutation carriers having RRS. Further studies should explore barriers to genetic testing services, as well as evaluate reasons why BRCA1/2 mutation carriers decline RRS.

Abstract
CONTEXT Obesity is associated with hypoferremia, but it is unclear if this condition is caused by insufficient iron stores or diminished iron availability related to inflammation-induced iron sequestration. OBJECTIVE To examine the relationships between obesity, serum iron, measures of iron intake, iron stores and inflammation. We hypothesized that both inflammation-induced sequestration of iron and true iron deficiency were involved in the hypoferremia of obesity. DESIGN Cross-sectional analysis of factors anticipated to affect serum iron. SETTING Outpatient clinic visits. PATIENTS Convenience sample of 234 obese and 172 non-obese adults. MAIN OUTCOME MEASURES Relationships between serum iron, adiposity, and serum transferrin receptor, C-reactive protein, ferritin, and iron intake analyzed by analysis of covariance and multiple linear regression. RESULTS Serum iron was lower (75.8+/-35.2 vs 86.5+/-34.2 g/dl, P=0.002), whereas transferrin receptor (22.6+/-7.1 vs 21.0+/-7.2 nmol/l, P=0.026), C-reactive protein (0.75+/-0.67 vs 0.34+/-0.67 mg/dl, P<0.0001) and ferritin (81.1+/-88.8 vs 57.6+/-88.7 microg/l, P=0.009) were higher in obese than non-obese subjects. Obese subjects had a higher prevalence of iron deficiency defined by serum iron (24.3%, confidence intervals (CI) 19.3-30.2 vs 15.7%, CI 11.0-21.9%, P=0.03) and transferrin receptor (26.9%, CI 21.6-33.0 vs 15.7%, CI 11.0-21.9%, P=0.0078) but not by ferritin (9.8%, CI 6.6-14.4 vs 9.3%, CI 5.7-14.7%, P=0.99). Transferrin receptor, ferritin and C-reactive protein contributed independently as predictors of serum iron. CONCLUSIONS The hypoferremia of obesity appears to be explained both by true iron deficiency and by inflammatory-mediated functional iron deficiency.

Abstract
Mild traumatic brain injury (MTBI) is associated with cognitive,affective, and physical sequelae. When symptoms persist for more than 3 months, a diagnosis of Post-Concussion Syndrome (PCS) is often given. The current study tracked symptom development to explore the natural sequelae of MTBI. Twenty-six MTBI patients received a comprehensive neuropsychological assessment at three intervals: within 1 week, at 4 months and at 7 months post-concussion. Based on DSMIV criteria and clinical judgment, two external raters diagnosed five MTBI participants with PCS. Results suggested that aspects of cognitive functioning of the symptomatic MTBI (i.e., PCS) participants were different from matched normal control (NC) subjects, and from the 21 MTBI patients who were asymptomatic, at 4 months. Asymptomatic MTBI participants improved in overall level of functioning from 4 to 7 months, but remained significantly different from NC participants in their reduced verbal fluency and working memory functioning.

Abstract
BACKGROUND In early breast cancer, variations in local treatment that substantially affect the risk of locoregional recurrence could also affect long-term breast cancer mortality. To examine this relationship, collaborative meta-analyses were undertaken, based on individual patient data, of the relevant randomised trials that began by 1995. METHODS Information was available on 42,000 women in 78 randomised treatment comparisons (radiotherapy vs no radiotherapy, 23,500; more vs less surgery, 9300; more surgery vs radiotherapy, 9300). 24 types of local treatment comparison were identified. To help relate the effect on local (ie, locoregional) recurrence to that on breast cancer mortality, these were grouped according to whether or not the 5-year local recurrence risk exceeded 10% (<10%, 17,000 women; >10%, 25,000 women). FINDINGS About three-quarters of the eventual local recurrence risk occurred during the first 5 years. In the comparisons that involved little (<10%) difference in 5-year local recurrence risk there was little difference in 15-year breast cancer mortality. Among the 25,000 women in the comparisons that involved substantial (>10%) differences, however, 5-year local recurrence risks were 7% active versus 26% control (absolute reduction 19%), and 15-year breast cancer mortality risks were 44.6% versus 49.5% (absolute reduction 5.0%, SE 0.8, 2p<0.00001). These 25,000 women included 7300 with breast-conserving surgery (BCS) in trials of radiotherapy (generally just to the conserved breast), with 5-year local recurrence risks (mainly in the conserved breast, as most had axillary clearance and node-negative disease) 7% versus 26% (reduction 19%), and 15-year breast cancer mortality risks 30.5% versus 35.9% (reduction 5.4%, SE 1.7, 2p=0.0002; overall mortality reduction 5.3%, SE 1.8, 2p=0.005). They also included 8500 with mastectomy, axillary clearance, and node-positive disease in trials of radiotherapy (generally to the chest wall and regional lymph nodes), with similar absolute gains from radiotherapy; 5-year local recurrence risks (mainly at these sites) 6% versus 23% (reduction 17%), and 15-year breast cancer mortality risks 54.7% versus 60.1% (reduction 5.4%, SE 1.3, 2p=0.0002; overall mortality reduction 4.4%, SE 1.2, 2p=0.0009). Radiotherapy produced similar proportional reductions in local recurrence in all women (irrespective of age or tumour characteristics) and in all major trials of radiotherapy versus not (recent or older; with or without systemic therapy), so large absolute reductions in local recurrence were seen only if the control risk was large. To help assess the life-threatening side-effects of radiotherapy, the trials of radiotherapy versus not were combined with those of radiotherapy versus more surgery. There was, at least with some of the older radiotherapy regimens, a significant excess incidence of contralateral breast cancer (rate ratio 1.18, SE 0.06, 2p=0.002) and a significant excess of non-breast-cancer mortality in irradiated women (rate ratio 1.12, SE 0.04, 2p=0.001). Both were slight during the first 5 years, but continued after year 15. The excess mortality was mainly from heart disease (rate ratio 1.27, SE 0.07, 2p=0.0001) and lung cancer (rate ratio 1.78, SE 0.22, 2p=0.0004). INTERPRETATION In these trials, avoidance of a local recurrence in the conserved breast after BCS and avoidance of a local recurrence elsewhere (eg, the chest wall or regional nodes) after mastectomy were of comparable relevance to 15-year breast cancer mortality. Differences in local treatment that substantially affect local recurrence rates would, in the hypothetical absence of any other causes of death, avoid about one breast cancer death over the next 15 years for every four local recurrences avoided, and should reduce 15-year overall mortality.

Subtle quantitative abnormalities in neuronal populations derived from the rhombic lip (i.e. arcuate nucleus at the ventral medullary surface, external granular layer of the cerebellum) have been reported in victims of the sudden infant death syndrome (SIDS). In this study, we examined the inferior olive, a major rhombic lip derivative, to determine if subtle rhombic lip abnormalities also involve this nucleus in SIDS. We analyzed the number and density of neurons and reactive astrocytes in the inferior olive in 29 SIDS cases and 29 controls. Computer-assisted cell counting procedures were used in sections stained with hematoxylin and eosin/Luxol fast blue. There was a significant difference in the postconceptionally age-adjusted mean for neuronal density between SIDS cases (7,687 +/- 255 neurons/mm(3)) and controls (8,889 +/- 255 neurons/mm(3)) (p = 0.002). The difference in age-adjusted mean neuronal number between SIDS cases (1,932 +/- 89 neurons/2 sections) and controls (2,172 +/- 89 neurons/2 sections) was marginally significant (p = 0.063). Reactive astrocytes were present in the inferior olive in SIDS cases, but their number, density, and developmental profile were not significantly different from that of control infants dying of diverse known causes. SIDS victims found dead in cribs, beds, and sofas, prone or supine had subtle olivary abnormalities, suggesting that affected infants are at risk in various sleeping situations. We propose that at least some SIDS victims experience intrauterine brainstem injury including the olivo-arcuato-cerebellar circuitry derived from the rhombic lip. These observations provide future directions for SIDS research concerning the role of early insults in pregnancy, the rhombic lip, and the interactions of the ventral medulla and cerebellum in cardioventilatory control.

Abstract
BACKGROUND Ocular perfusion pressure is commonly defined as mean arterial pressure minus intraocular pressure (IOP). Changes in mean arterial pressure or IOP can affect ocular perfusion pressure. IOP has not been studied in this context in the prone anesthetized patient. METHODS After institutional human studies committee approval and informed consent, 20 patients (American Society of Anesthesiologists physical status I-III) without eye disease who were scheduled for spine surgery in the prone position were enrolled. IOP was measured with a Tono-pen XL handheld tonometer at five time points: awake supine (baseline), anesthetized (supine 1), anesthetized prone (prone 1), anesthetized prone at conclusion of case (prone 2), and anesthetized supine before wake-up (supine 2). Anesthetic protocol was standardized. The head was positioned with a pinned head-holder. Data were analyzed with repeated-measures analysis of variance and paired t test. RESULTS Supine 1 IOP (13 +/- 1 mmHg) decreased from baseline (19 +/- 1 mmHg) (P < 0.05). Prone 1 IOP (27 +/- 2 mmHg) increased in comparison with baseline (P < 0.05) and supine 1 (P < 0.05). Prone 2 IOP (40 +/- 2 mmHg) was measured after 320 +/- 107 min in the prone position and was significantly increased in comparison with all previous measurements (P < 0.05). Supine 2 IOP (31 +/- 2 mmHg) decreased in comparison with prone 2 IOP (P < 0.05) but was relatively elevated in comparison with supine 1 and baseline (P < 0.05). Hemodynamic and ventilatory parameters remained unchanged during the prone period. CONCLUSIONS Prone positioning increases IOP during anesthesia. Ocular perfusion pressure could therefore decrease, despite maintenance of normotension.

Abstract
BACKGROUND Mutations in the p53 tumor suppressor gene may correlate with an increased risk of recurrence and disease progression in patients with bladder carcinoma. The ability to accurately and sensitively detect p53 mutations in cytology specimens may be of benefit in the treatment of bladder carcinoma patients with superficial, minimally invasive disease. METHODS Genomic DNA was isolated from 49 cases, each of which was comprised of matched bladder tumor tissue, bladder wash, and voided urine specimens obtained concurrently at a single institution. The genomic DNA was analyzed for mutations in the p53 tumor suppressor gene using a p53 mutation detection assay. Automated dideoxy sequencing of mutant specimens also was performed. RESULTS Of the 49 cases, 29 (59%) showed no evidence of p53 mutations in the tumor, bladder wash, or voided urine specimens. Of the remaining 20 cases, 19 showed evidence of mutations in the tumor. Of these 19 p53 mutant bladder tumors, 16 (84%) were detected in the matched bladder wash and 16 (84%) were detected in the matched voided urine specimens. One case resulted in the detection of mutant p53 in the voided urine and the bladder wash, but not in the tumor. Analysis of the results between tumor tissue and bladder wash or tumor and voided urine showed 84.2% sensitivity, 96.8% specificity, and 91.8% accuracy. Sequence analysis of the mutant cases showed that the mutations detected in the tumor tissue were the same mutations detected in the bladder wash and the voided urine specimens. CONCLUSIONS Both voided urine and bladder wash specimens from patients with bladder carcinoma were found to provide a high rate of clinical accuracy for the determination of the p53 gene status in patients with bladder tumors.

Abstract
Posttraumatic nightmares are a hallmark of PTSD and distinct from general nightmares as they are often repetitive and faithful representations of the traumatic event. This paper presents data from a pilot study that examined the use of Imagery Rehearsal in treating combat-related nightmares of 12 Vietnam veterans with PTSD. Three treatment groups, comprising 4 veterans in each, completed standardised treatment across 6 sessions. Treatment effects were investigated using nightmare diaries and established instruments, including the IES-R, BDI, BAI, and SCL-90-R. The data demonstrate significant reductions in nightmares targeted, and improvements in PTSD and comorbid symptomatology. The paper recommends that, on the basis of the promising preliminary data, a randomised control trial be established to assess imagery ability and attitude toward nightmares.

Abstract
PURPOSE To investigate the rate of undiagnosed rheumatologic diseases and hepatitis C infection among patients with the clinical diagnosis of Mooren ulcer seen at Aravind Eye Hospital, Madurai, South India. METHODS Twenty-one patients with the clinical diagnosis of Mooren ulcer and 44 control patients underwent a complete ophthalmic history and examination, as well as serologic testing for antinuclear antibodies, rheumatoid factor, antineutrophil cytoplasmic antibodies, herpes simplex virus 1 antibodies, and hepatitis C virus antibodies. RESULTS There were no statistically significant differences in the rates of seropositivity for antinuclear antibodies, rheumatoid factor, antineutrophil cytoplasmic antibodies, herpes simplex virus 1 antibodies, and hepatitis C virus antibodies between patients with Mooren ulcer and control patients. Two patients with Mooren ulcer and four control patients were found to have a rheumatoid factor titer of greater than 1:20. One of the control patients, but none of the patients with Mooren ulcer, was found to have serologic evidence of hepatitis C infection. A history of corneal trauma, surgery, or infection was reported by 68% of patients with Mooren ulcer, compared with 20% of control patients (P < .001). Among patients with Mooren ulcer, bilateral disease occurred in 37% of patients, visual acuity was reduced to light perception in 15% of eyes, and perforation occurred in 19% of eyes. CONCLUSIONS Nineteen (90%) of 21 patients with the clinical diagnosis of Mooren ulcer were found to have no evidence of an underlying rheumatologic disease by history, examination, or serologic testing, and none was seropositive for hepatitis C. However, patients with Mooren ulcer were more likely than control patients to report a history of corneal trauma, surgery, or infection.

Abstract
Detecting somatic mutations in patient specimens is challenging because of the wide variation in quality and quantity of genomic DNA in clinically derived material. In cancer specimens, the challenge of detecting mutations is usually compounded by the presence of large numbers of nonmutated normal cells that dampen the relative signal that can be obtained from employing any mutation detection strategy. In the case of somatic mutations in the gene encoding the tumor suppressor, p53, a clinically useful mutation detection assay must be able to detect a wide variety of types of mutations scattered over five coding exons and their flanking intron sequences. This study examined the ability of a mutation detection strategy, termed NIRCA, to identify single-base mutations in the clinically relevant domain of the p53 gene. This strategy relies on RNase digestion-mediated cleavage of double-stranded copy RNA transcribed in vitro from polymerase chain reaction (PCR)-amplified genomic templates to detect mismatched base pairs resulting from hybridization of complimenting mutant and wild-type copy RNA strands. This assay system was found to robustly detect all twelve possible mismatches and the plus one and minus one frame shifts. Furthermore, the assay could detect mutations in clinical specimens when the mutant alleles composed as few as 4% of the total population of alleles isolated in bulk specimen genomic DNA. This mutation detection strategy worked efficiently in bladder, breast, colon and lung tumors as well as sediments from bladder cytology specimens.

Abstract
Considerable attention has been devoted to the MMPI in the assessment of combat-related PTSD. To date, published data have focused almost exclusively on American Vietnam veterans. This study investigated MMPI-2 profiles of 100 Australian Vietnam veterans admitted to an intensive PTSD treatment program. Comparisons with United States (U.S.) data suggested strong similarities between the American and Australian populations in terms of F-scale elevations and typical 3-point code types (8-7-2). However, the American samples showed relatively higher elevations of Scales 4 and 6, suggesting social alienation and a tendency to externalize, while a subgroup of Australian veterans showed a greater propensity for somatization (Scale 1). The results provide overall support for the generalizability of American MMPI data to an alternative cultural group of combat veterans.

Abstract
OBJECTIVE To describe the 123-I-MIBG scintigraphic, CT, MRI, operative and pathological findings in a case of malignant prostatic paraganglioma and to review the literature on this very rare tumor. EXPERIMENTAL DESIGN Clinical imaging and pathological correlation of data in a referred patient. SETTING Regional referral center and tertiary referral academic medical center. PATIENT 17 year old man presenting with painless hematuria and a large prostatic mass. Interventions and measures. Renal ultrasound, transrectal ultrasound, ultrasound guided prostatic biopsy, pelvic CT and MRI, planar and SPECT 123-I-MIBG scintigraphy, and surgical exploration. RESULTS The patient had a significant hydronephrosis of the left kidney and marked enlargement (120 ml) of the prostate gland by ultrasound. Ultrasound guided biopsies of the prostate and a left pelvic lymph node revealed a neuroendocrine tumor staining positive for chromogranin. CT and MRI revealed a large tumor of the prostate invading the seminal vesicles, bladder and rectum with extensive pelvic lymph node spread. The primary tumor and one of the nodes were shown to be 123-I-MIBG avid confirming the neuroendocrine nature of the tumor. The lesion was unresponsive to chemotherapy and unresectable at surgical exploration. CONCLUSIONS To date there have only been 5 reports of prostatic paragangliomas. To our knowledge this is the first to have been studied by MIBG scintigraphy and like most paragangliomas it was MIBG-avid.

Abstract
The light-dependent step in chlorophyll synthesis by higher plants involves hydrogen transfer from NADPH+ to the porphyrin protochlorophyllide catalysed by the photoenzyme protochlorophyllide reductase. The light intensity dependence of the process has been studied in vitro using wheat etioplast membranes. The results suggest that a single photochemical event is involved in the photoconversion. In support of this conclusion we also demonstrate that illumination of these membranes with a train of ultrashort (150 fs) flashes resulted in chlorophyll accumulation. The significance of the findings in terms of possible mechanisms for the reductase are discussed.

Abstract
Nereistoxin (100 microM, 2-10 min) blocks nicotinic receptors in the intact chick ciliary ganglion. This effect mimics blockade by the reducing agent dithiothreitol (2 mM, 20 min), which is not reversed until oxidation with dithiobisnitrobenzoic acid (1 mM, 5 min). After treating intact ganglia with either nereistoxin or dithiothreitol, the affinity alkylating agent bromoacetylcholine causes irreversible blockade that cannot be reversed by dithiobisnitrobenzoic acid. These data suggest that nereistoxin, or a metabolite, acts to reduce nicotinic receptors, although nereistoxin differs from dithiothreitol in that agonists only partially protect against nereistoxin reduction. In studies on chick retina, we previously proposed that a metabolite of nereistoxin (such as dihydronereistoxin) is the actual reducing agent for neuronal nicotinic receptors. Current findings in chick ciliary ganglion supporting this hypothesis include: 1) changing pH alters the minimal nereistoxin concentration needed for blockade in intact ganglia, but has little effect on the minimal concentration needed for dithiothreitol, 2) application of a quaternary analog of nereistoxin has little effect on intact ganglion, but a quaternary analog of dihydronereistoxin blocks nicotinic receptors by reduction, 3) nereistoxin weakly oxidizes rather than reduces immunoprecipitated receptors from chick brain and 4) in whole-cell patch-clamp studies, nereistoxin clearly does not reduce receptors on chick ciliary neurons, although dihydronereistoxin mimics receptor blockade by dithiothreitol, and requires oxidation by dithiobisnitrobenzoic acid for reactivation. Together, these data suggest that nereistoxin is not a direct reducing agent for neuronal nicotinic receptors.

Abstract
Cytokines play a vital role in the host immune response by regulating the development and function of immunocompetent cells. To explore the possibility that tumors may alter the host response via release of immunomodulatory cytokines, we studied two different skin cancers, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) as models. By RT-PCR, we found that the type 2 cytokines, IL-4 and IL-10, were strongly expressed in BCC compared with matched PBMC. Furthermore, IL-10 was more strongly expressed in SCC compared with benign growths. To identify the cell types responsible for production of these cytokines, tumor and tumor-infiltrating lymphocyte (TIL) cell lines were derived from BCC and SCC biopsy specimens. IL-2 and IFN-gamma mRNAs were expressed in TIL, while IL-10 mRNA were strongly expressed in BCC lines. In addition, IL-10 was detected in culture supernatants from BCC and SCC cell lines by ELISA and in tissue sections by immunohistology. TIL lines derived from these tumors demonstrated proliferative activity to autologous tumor cells in the presence of APCs, dependent on the addition of low concentrations of rIL-2 or neutralizing anti-IL-10 mAb in the culture medium. Furthermore, treatment of BCC with intralesional IFN-alpha induced tumor regression with concomitant up-regulation of IL-2 and down-regulation of IL-10 mRNA expression in lesions. These data suggest that tumor production of the cytokine, IL-10, may provide a mechanism for evading the local T cell-mediated immune response.

Abstract
The skin lesions of patients with atopic dermatitis provide a model to study immunoregulation in human allergy. To determine the local cytokine pattern of cells present (both endogenous and recruited) at the site of disease, we extracted RNA from skin biopsy specimens from patients with atopic dermatitis, allergic contract dermatitis, and positive tuberculin reactions and used PCR to assay for cytokine mRNA. cDNAs were normalized to the intensity of the CD3 delta PCR product as a marker of T cell mRNA. We found overexpression of IL-10 mRNA in atopic dermatitis lesions, in comparison with allergic contact dermatitis lesions and tuberculin reactions. In contrast, IL-4 mRNA was most strongly expressed in allergic contact dermatitis lesions and IFN-gamma mRNA was the predominant cytokine in tuberculin reactions. Using an anti-IL-10 mAb with immunoperoxidase, we localized IL-10 protein to large mononuclear cells in the dermal infiltrate of atopic lesions. After immunomagnetic sorting of mononuclear cell populations from PBMC of atopic dermatitis subjects, IL-10 mRNA as measured by PCR was found to be strongly expressed in CD14+ cells. Spontaneous release of IL-10 from PBMC-derived adherent cells was greater in atopic dermatitis donors than normal controls. We therefore renormalized skin biopsy cDNA according to the level of beta-actin PCR product, as a marker of total cellular mRNA, and found by PCR that IL-10 was nevertheless greatest in atopic dermatitis subjects. We conclude that the relative overexpression of IL-10 in atopic dermatitis greatest in atopic dermatitis subjects. We conclude that the relative overexpression of IL-10 in atopic dermatitis may contribute to the up-regulation of humoral responses and the down-regulation of Th1 responses.
