Abstract
INTRODUCTION The Hall technique is a biological caries management approach commonly used within the field of paediatric dentistry. The technique involves the placement of a preformed metal crown (PMC) without local anaesthetic, caries removal or tooth preparation. Despite being widely taught across dental schools in the United Kingdom, evidence from the literature suggests that PMCs are seldom used in general dental practice, even by newly qualified dentists. This study aimed to evaluate the experience and self-reported confidence of Foundation Dentists (FDs) in the North West of England in the placement of preformed metal crowns using the Hall technique. MATERIALS AND METHODS An anonymous questionnaire was distributed to 117 Foundation Dentists in the North West of England. RESULTS Forty-six questionnaires were returned, giving a response rate of 39%. The results revealed that 80.4% of FDs felt "somewhat," "quite" or "extremely" confident with the Hall technique at the point of graduation. This increased to 85.3% upon completion of Dental Foundation Training. CONCLUSION Foundation Dentists' self-reported confidence in the Hall technique was reasonably high both at the point of qualification and upon completing Dental Foundation Training. Nevertheless, many of the Foundation Dentists felt that they would benefit from further postgraduate training on the technique.

Abstract
Introduction Dental neglect presents a global concern and is a shared public challenge for all healthcare professionals, including general medical practitioners (GPs). Previous literature highlights a lack of training among GPs and suggests that barriers are present to reporting concerns of dental neglect.Aims To investigate the current awareness of child dental neglect among GPs in Greater Manchester and to investigate barriers to the reporting of concerns.Methods An anonymous, electronic questionnaire was distributed to GPs in Greater Manchester. Respondents reported their experience and training in child dental neglect and their management of suspected cases. Results were assessed using descriptive analysis.Results In total, 25 GPs completed the questionnaire. It was found 60% received undergraduate child protection training and 96% completed postgraduate training. Only 20% felt adequately trained in the referral of suspected child dental neglect and the majority acknowledged that more training is required. Furthermore, 42% had been suspicious of child dental neglect; however, only 80% recorded their observations. Plus, 32% had suspected child dental neglect and not completed a referral. Common barriers to reporting included lack of knowledge of referral procedures and lack of certainty of diagnosis.Conclusion Barriers to referral of suspected cases of neglect were reported and there is a demand for further training among GPs.

Abstract
BACKGROUND: Australia has a low incidence of TB and has committed to eliminating the disease. Identification of risk factors associated with TB is critical to achieving this goal.METHODS: We undertook a prospective cohort study involving persons receiving TB treatment in four Australian jurisdictions. Risk factors and their association with delayed treatment completion (treatment delayed by at least 1 month) were analysed using univariate analyses and multivariate logistic regression.RESULTS: Baseline surveys were completed for 402 persons with TB. Most (86.1%) were born overseas. Exposure to a person with TB was reported by 19.4%. Diabetes mellitus (10.2%), homelessness (9.2%), cigarette smoking (8.7%), excess alcohol consumption (6.0%) and mental illness (6.2%) were other common risk factors. At follow-up, 24.8% of patients had delayed treatment completion, which was associated with adverse events (34.1%, aOR 6.67, 95% CI 3.36-13.27), excess alcohol consumption (6.0%, aOR 21.94, 95% CI 6.03-79.85) and HIV co-infection (2.7%, aOR 8.10, 95% CI 1.16-56.60).CONCLUSIONS: We identified risk factors for TB and their association with delayed treatment completion, not all of which are routinely collected for surveillance purposes. Recognition of these risk factors should facilitate patient-centred care and assist Australia in reaching TB elimination.

Abstract
White enamel lesions are a common presentation to the general dentist and aesthetic concerns are the most frequent presenting problem. Aetiology may be multifactorial and management of such lesions is heavily dependent on the cause. In the paediatric patient, differentiating white lesions caused by caries, fluorosis and genetic and developmental disorders is key to offering optimal long-term treatment outcomes. Early intervention allows for carefully planned management of less common disorders. Many of these disorders exist along a spectrum, and white lesions offer a useful clue to prompt intervention and referral to the relevant specialists. This article overviews common white lesions of the teeth and outlines the hierarchy of management options available.

Abstract
Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. It is a major health concern and causes substantial morbidity and mortality. It is imperative that the signs of sepsis are identified early in both adult and paediatric patients and appropriately escalated to initiate early treatment and improve prognosis. This paper aims to discuss the change in classification from the previous systemic inflammatory response syndrome (SIRS) criteria to the current definition in adults and also the unchanged definition in children. The hallmark signs of sepsis (both red and amber flags) are discussed in relation to their underlying cellular mechanisms to provide a comprehensive overview for clinicians in primary care, hospital and community settings. The rise of antimicrobial resistance is also an increasing global health concern with resistant bacteria from common infections likely to result in greater patient morbidity and worse outcomes.A literature search identified reported sepsis cases in dentistry through searches in Ovid Medline and Embase from January 1990 to December 2019. Only primary studies were included with no restrictions on languages. Four articles were identified which reported sepsis associated with tooth extractions, dental abscess and submental/submandibular cellulitis. It is well known that locoregional infections of dental origin have the potential to cause sepsis. Therefore, dental healthcare professionals need to be vigilant and understand the specific signs and escalation protocols to ensure patient safety.

Abstract
Aim The aim of this survey was to determine compliance towards dental radiography selection criteria for paediatric patients undergoing new patient examinations in specialised tertiary care centres in the United Kingdom.Methods Five university-associated dental hospitals were included in this study. Retrospective data was collected reviewing all paediatric patients on the new patient assessment clinics, where dental imaging was requested or the patient had relevant previous imaging. Data was collected from 28 June 2018, continuing retrospectively for a maximum of six months or until 150 patients were reached. Patients referred solely for orthodontic assessment were excluded.Results Seven hundred and fifty patients were included with an average age of eight years - 95.5% of patients had a radiographic justification provided. All patients were grouped into 56 disease categories and a total range of one cross-sectional and nine planar radiographs were prescribed in this cohort. Each radiograph was assessed for compliance to the Faculty of General Dental Practice, European Association of Paediatric Dentistry and national Italian guidelines for dental diagnostic imaging. Additionally, selection criteria for CBCT scans were taken from SEDENTEXCT guidelines. Full panoramic radiographs were the most commonly prescribed at 34.8% (n = 261). However, this demonstrated the lowest compliance rate as per selection criteria at 75.9%. This was due to referrers requesting radiographs primarily for assessing dental development (18.8%; n = 49) and caries assessment (2.7%; n = 7). Other radiograph formats demonstrated varying levels of guideline compliance ranging from 93.5-100%.Conclusion This study identifies common radiograph request errors and can inform paediatric clinicians to improve compliance to guidelines and reduce radiation exposure to young patients.

Abstract
Dental trauma is common in the UK, with more than one in ten children having experienced some form of dental trauma. In addition, one in ten patients have been reported to have experienced dental trauma before orthodontic treatment. A recent survey of orthodontists’ knowledge and experience of orthodontic management of traumatised teeth has highlighted large inconsistencies in management of traumatised teeth among UK orthodontists, highlighting the need for further information or training on orthodontic management of traumatised teeth. Therefore, the following guidelines have been developed in order to provide an evidence-based approach to treat this cohort of patients. The following guidance is based on the available literature, expert opinion and UK orthodontists’ consensus drawn from a recent survey.

Abstract
INTRODUCTION The quality assurance of undergraduate dental education in the UK is regulated by the General Dental Council who describe the competencies expected of the newly qualified dentist or "safe beginner." Whilst the literature has explored the level of undergraduate training in a number of dental specialties within the UK, there is a paucity of information on the UK curriculum for undergraduate paediatric dental teaching. AIMS This study aimed to assess the undergraduate teaching of paediatric dentistry within dental schools in the UK. METHODS An anonymous questionnaire was distributed to all 16 UK dental schools via email. RESULTS Twelve questionnaires were completed, giving a response rate of 75%. First exposure to both academic teaching and clinical teaching in paediatric dentistry ranged from years 1-4. Whilst there were broad similarities between units with regard to core components of the curricula, there were notable differences including the teaching of regenerative endodontics (75%) and the use of the titanium trauma splint (58%). Silver diamine fluoride was only used clinically in one unit (8%), and non-vital pulpotomy was taught by two units (16%). There was also considerable heterogeneity in assessment methods between universities. CONCLUSION The undergraduate paediatric dental curriculum is broadly similar between UK dental schools. However, there are discrepancies in assessment methods and the teaching of new advances.

Abstract
Purpose To determine in which clinical situations it is indicated or contra-indicated to prescribe cone beam computed tomography (CBCT) for paediatric patients. Methods Systematic review of in vivo paediatric research studies of diagnostic efficacy using CBCT, with supplementary searches for guideline documents on CBCT and for systematic reviews permitting inclusion of ex vivo and adult studies. Results After screening, 190 publications were included, mostly case studies. No systematic reviews were found of in vivo paediatric research. Fourteen studies of diagnostic efficacy were identified. The supplementary searches found 18 guideline documents relevant to the review and 26 systematic reviews. The diagnostic efficacy evidence on CBCT was diverse and often of limited quality. There was ex vivo evidence for diagnostic accuracy being greater using CBCT than radiographs for root fractures. The multiplanar capabilities of CBCT are advantageous when localising dental structures for surgical planning. Patient movement during scanning is more common in children which could reduce diagnostic efficacy. Conclusions No strong recommendations on CBCT are possible, except that it should not be used as a primary diagnostic tool for caries. Guidelines on use of CBCT in the paediatric age group should be developed cautiously, taking into account the greater radiation risk and the higher economic costs compared with radiography. CBCT should only be used when adequate conventional radiographic examination has not answered the question for which imaging was required. Clinical research in paediatric patients is required at the higher levels of diagnostic efficacy of CBCT.

Abstract
Introduction Child abuse and neglect present a significant global concern, therefore, it is imperative that dental professionals can identify children at risk. Previous literature has suggested that general dental practitioners (GDPs) do not feel adequately trained to do so and that there is a gap between the suspicion of abuse and onward referral.Aims To assess the experience of paediatric safeguarding reporting among GDPs in Greater Manchester and investigate the current barriers to reporting safeguarding concerns.Methods An anonymous questionnaire was distributed via email to a sample of general dental practices in Greater Manchester.Results Thirty-six questionnaires were completed, giving a 36% response rate. Fifty-eight percent of respondents had received undergraduate training and 83% had received postgraduate training. Eighty-one percent felt that GDPs require further training and support. Fifty-eight percent of GDPs had been suspicious of at least one case of child abuse or neglect, however, only 28% had completed an onwards referral. Common barriers to reporting included: fear of violence to the child; lack of certainty of diagnosis; and lack of confidence in their suspicions.Conclusion Barriers to the referral of suspected cases of abuse or neglect are still commonly reported. There is a strong demand for further child protection training among GDPs.

Abstract
Abstract
BACKGROUND
Targeting kinases as regulators of cellular processes that drive cancer progression is a promising approach to improve patient outcome in GBM management. The glycogen synthase kinase 3 (GSK-3) plays a role in cancer progression and is known for its pro-proliferative activity in gliomas. The anti-proliferative and cytotoxic effects of the GSK-3 inhibitor AZD2858 were assessed in relevant in vitro and in vivo glioma models to confirm GSK-3 as a suitable target for improved single agent or combination treatments.
MATERIAL AND METHODS
The immortalised cell line U251 and the patient derived cell lines GBM1 and GBM4 were used in in vitro studies including MTT, clonogenic survival, live cell imaging, immunofluorescence microscopy and flow cytometry to assess the cytotoxic and anti-proliferative effects of AZD2858. Observed anti-proliferative effects were investigated by microarray technology for the identification of target genes with known roles in cell proliferation. Clinical relevance of targeting GSK-3 with the inhibitor either for single agent or combination treatment strategies was determined by subcutaneous and orthotopic in vivo modelling. Whole mount mass spectroscopy was used to confirm drug penetration in orthotopic tumour models.
RESULTS
AZD2858 was cytotoxic at low micromolar concentrations and at sub-micromolar concentrations (0.01 - 1.0 μM) induced mitotic defects in all cell lines examined. Prolonged mitosis, centrosome disruption/duplication and cytokinetic failure leading to cell death featured prominently among the cell lines concomitant with an observed S-phase arrest. No cytotoxic or anti-proliferative effect was observed in normal human astrocytes. Analysis of the RNA microarray screen of AZD2858 treated glioma cells revealed the dysregulation of mitosis-associated genes including ASPM and PRC1, encoding proteins with known roles in cytokinesis. The anti-proliferative and cytotoxic effect of AZD2858 was also confirmed in both subcutaneous and orthotopic in vivo models. In addition, combination treatment with AZD2858 enhanced clinically relevant radiation doses leading to reduced tumour volume and improved survival in orthotopic in vivo models.
CONCLUSION
GSK-3 inhibition with the small molecule inhibitor AZD2858 led to cell death in glioma stem cells preventing normal centrosome function and promoting mitotic failure. Normal human astrocytes were not affected by treatment with the inhibitor at submicromolar concentrations. Drug penetration was observed alongside an enhanced effect of clinical radiotherapy doses in vivo. The reported aberrant centrosomal duplication may be a direct consequence of failed cytokinesis suggesting a role of GSK-3 in regulation of mitosis in glioma. GSK-3 is a promising target for combination treatment with radiation in GBM management and plays a role in mitosis-associated events in glioma biology.

Abstract
BACKGROUND/AIM There is a lack of research into orthodontic movement and management strategies of traumatized teeth. The aim of this survey was to assess the knowledge of UK-based orthodontists in the orthodontic management of traumatized teeth. MATERIALS/METHODS A 24-item questionnaire survey was electronically distributed to all members of the British Orthodontic Society. RESULTS A total of 213 respondents completed the survey with the majority of these being UK registered specialists in orthodontics. Three responses were excluded as one was not based within the UK and two were orthodontic trainees with <1 year of experience, leaving a total of 210 respondents. The majority had orthodontically treated up to three patients with a history of dental trauma in the preceding 3 months. Obtaining a trauma history was done by the majority of respondents. A wide variation in times waited by respondents before orthodontically treating teeth with different types of traumatic injuries was observed. Similarly, the preferred orthodontic management strategies of traumatized teeth differed substantially among respondents. Almost all respondents were interested in further training in the management of dental trauma. CONCLUSIONS The study showed a wide variation in the orthodontic management of traumatized teeth among UK-based orthodontists. Further training and national guideline establishment are indicated for orthodontic management of traumatized teeth in the UK.

Abstract
While suicide and injury account for increased mortality, a large volume of premature deaths in psychiatry are due to medical conditions. The Royal College of Psychiatrists recommend that every new psychiatric admission should have a thorough physical examination within 24 hours of their admission. We randomly reviewed charts of 50 new admission to the Acute Psychiatric Unit to check the adherence to these guidelines. Forty patients (80%) had complete physical examination, nine patients (18%) had incomplete physical examination, and one patient (2%) had no physical examination in the Re Audit. This compares to 32 patients (64%) had complete physical examination, 16 patients (32%) had partial physical examination, and two patients had no physical examination (4%), in the first audit.There has been overall improvement in the physical examination since the first audit. However documentation of vital signs and weight remained and issue. Chaperon documentation had improved in the re-audit, although further improvement still required.

Abstract
A 5-year-old female spayed Shetland sheepdog presented for evaluation of bandage sores on the left pelvic limb after a splint was placed to stabilise a digit fracture incurred approximately 2 weeks previously. Multiple areas of necrosis were identified upon bandage removal. After debridement of devitalised tissue, a 4 cm wound on the plantar surface of the metatarsal bones (with exposed bone and tendons) remained. The Papineau technique (which involves removal of infected or necrotic tissue, placement of autogenous cancellous bone graft within a wound, and delayed skin closure) was used to treat this wound. Use of bone graft in this manner aims to promote early granulation tissue formation and reduce the time until wound reconstruction can be performed. Autogenous cancellous bone graft was harvested from the proximal humerus and placed within the metatarsal wound. Once a healthy granulation tissue bed was noted to cover the bone graft, a meshed full thickness skin graft was placed. To our knowledge, this is the first report of the Papineau technique being used for this purpose in a dog.

Abstract
BackgroundLittle is known about the availability and uptake of health and welfare services by women with postnatal depression in different countries.AimsWithin the context of a cross cultural research study, to develop and test methods for undertaking quantitative health services research in postnatal depression.MethodInterviews with service planners and the collation of key health indicators were used to obtain a profile of service avail ability and provision. A service use questionnaire was developed and administered to a pilot sample in a number of European study centres.ResultsMarked differences in service access and use were observed between the centres, including postnatal nursing care and contacts with primary care services. Rates of use of specialist services were generally low. Common barriers to access to care included perceived service quality and responsiveness. On the basis of the pilot work, a postnatal depression version of the Service Receipt Inventory was revised and finalised.ConclusionsThis preliminary study demonstrated the methodological feasibility of describing and quantifying service use, highlighted the varied and often limited use of care in this population, and indicated the need for an improved understanding of the resource needs and implications of postnatal depression.

Abstract
Aims and MethodThe Irish Psychiatric Association conducted a national survey of psychiatric services in Ireland to examine clinical resources in relation to the relative affluence of catchment areas. A consultant psychiatrist from each catchment area was sent a postal survey form (August 2002) and the data received were cross-referenced with measures of relative affluence.ResultsThere was a 72% response rate. A negative relationship emerged between indices of need and both the number of acute beds and the number of consultant psychiatrists per head of the population.Clinical ImplicationsThe results of this survey indicate that clinical resources in mental health in Ireland are not concentrated in areas of greatest need, but paradoxically have been best developed in areas of greatest affluence.

Abstract
Introduction Pelvic radiography is a frequent investigation. European guidelines aim to ensure appropriate use and adequate quality. When initial images are inadequate, repeat radiographs are often required, which may have significant patient safety and economic implications. Objectives The study aimed to assess the adequacy of pelvic imaging across three orthopaedic centres, to identify causes for inadequate imaging and to establish the cost of inadequate imaging from financial and patient safety perspectives. Methods Pelvic radiographs were identified on Picture Archiving and Communication System software at three UK hospitals. Radiographs were assessed against European guidelines and indications for repeat imaging were analysed. Results A total of 1,531 sequential pelvic radiographs were reviewed. The mean age of patients was 60 years (range 5 months to 101 years). Of this total, 51.9% of images were suboptimal, with no significant difference across the three hospitals (P > 0.05). Hospital 3 repeated radiographs in 6.3% of cases, compare with 18.1% and 19.7% at hospitals 1 and 2, respectively (P > 0.05). Hospital 3 identified pathology missed on the initial radiograph in 1% of cases, compared with 5.4% and 5.5% at hospitals 1 and 2, respectively (P > 0.05). Out-of-hours imaging is associated with a higher rate of suboptimal quality (69.1%) compared with normal working hours (51.3%; P = 0.006). Adequacy rates vary with age (χ 2 = 43.62, P < 0.001). Risk of having a suboptimal radiograph increases above the age of 60-years (χ 2 = 4.45, P < 0.05). The annual cost of repeat radiographs was £56,200 per hospital. Discussion and conclusion High rates of pelvic radiograph inadequacy can lead to missed pathology and the requirement for repeat imaging, which has significant patient safety and financial implications. Risk factors for inadequate radiographs include older patients and those having out-of-hours imaging.

Abstract
INTRODUCTION Peripheral facial paralysis (PFP), a frequent complication during infection with the human immunodeficiency virus (HIV), is a major cause of morbidity for these patients. The aim of this study was to show the place of unilateral PFP in the discovery of HIV infection in tropical areas. MATERIAL AND METHODS This is a descriptive cross-sectional study with prospective data collection over a 12-month period, in the ENT departments of the Ignace Deen National Hospital and Neurology Hospital of the Sino-Guinean Friendship Hospital (CHU de Conakry). RESULTS Of the 2517 patients received during the study period, 64 had PFP, a prevalence of 2.54%. HIV serology was performed in 56 patients, 24 of whom had a positive serological reaction, a prevalence of 42.86%. The young adult population was the most exposed, with an average age of 34.5 years. There were 9 men and 15 women, or a sex ratio of 0.6. In 70.83% of cases, the consultation period occurred between the 1st and 3rd week. Unilateral facial asymmetry and persistent opening of the palpebral fissure were the main clinical signs. A total of 75% of our patients were infected with HIV1. CD4 levels ranged from 175 to 400/mm3. All our patients had received PFP and HIV treatments. The evolution was marked by a complete recovery with no sequelae of PFP in 62.5% of cases. CONCLUSION The occurrence of isolated PFP in apparently healthy adults should suggest seroconversion to HIV. The prognosis of these PFPs is often good despite the delay in diagnosis.

Abstract
Changes in gynaecological practice have resulted in a significant reduction in surgical exposure for trainees. We have attempted to assess surgical experience among obstetric and gynaecology SpR's in Ireland using an anonymous on-line questionnaire. Trainees were asked to assess their own ability to perform a variety of general gynaecological procedures. There was a 97% response rate (29/33 trainees). There were 11 trainees who were in the final or penultimate year of the scheme. This group were analysed separately to assess competency rates in those approaching the end of the scheme. They were subdivided in to those who have completed one year in a general hospital doing pure gynaecology and those who have not. Approximately half of this group (6/11) had completed a pure gynaecology year. All of these trainees deemed themselves competent to perform all general gynaecological procedures listed, with the exception of trans-urethral tape procedures, for which 3/6 reported the requirement of direct supervision. Only 2/6 deemed themselves competent to perform a total laparoscopic hysterectomy. Year 4/5 trainees who had not completed a pure gynaecology year displayed significantly lower competency rates for most of the procedures. With the current changes in gynaecological practice, these results highlight the importance of dedicated gynaecological surgical training.

Abstract
BACKGROUND Lung cancer remains the leading cause of cancer-related death, largely owing to the lack of effective treatments. A tumour vascular targeting strategy presents an attractive alternative; however, the molecular signature of the vasculature in lung cancer is poorly explored. This work aimed to identify novel tumour vascular targets in lung cancer. METHODS Enzymatic digestion of fresh tissue followed by endothelial capture with Ulex lectin-coated magnetic beads was used to isolate the endothelium from fresh tumour specimens of lung cancer patients. Endothelial isolates from the healthy and tumour lung tissue were subjected to whole human genome expression profiling using microarray technology. RESULTS Bioinformatics analysis identified tumour endothelial expression of angiogenic factors, matrix metalloproteases and cell-surface transmembrane proteins. Predicted novel tumour vascular targets were verified by RNA-seq, quantitative real-time PCR analysis and immunohistochemistry. Further detailed expression profiling of STEAP1 on 82 lung cancer patients confirmed STEAP1 as a novel target in the tumour vasculature. Functional analysis of STEAP1 using siRNA silencing implicates a role in endothelial cell migration and tube formation. CONCLUSIONS The identification of cell-surface tumour endothelial markers in lung is of interest in therapeutic antibody and vaccine development.

Abstract
OBJECTIVES Polyuria increases the risk of dehydration and lithium toxicity in lithium-treated patients. Risk factors have been inconsistently described and the variance of this adverse effect remains poorly understood. This study aimed to establish independent risk factors for polyuria in a community, secondary-level lithium-treated sample of patients. METHODS This was a cross-sectional study of the lithium-treated patients attending a general adult and an old age psychiatry service. Participants completed a 24-hour urine collection. Urine volume and the presence of polyuria were the outcomes of interest. The relationship between outcome and the participant's demographic and clinical characteristics was explored with univariable and multivariable analysis. RESULTS A total of 122 participants were included in the analysis, with 38% being diagnosed with polyuria. Female gender and increased body weight independently predicted the presence of polyuria (standardized regression coefficient 1.01 and 0.94, respectively; p = 0.002 and p = 0.003, respectively). Female gender and increased body weight, lithium dose, and duration of lithium treatment independently predicted higher 24-hour urine volumes (standardized regression coefficients 0.693, p < 0.0005; 0.791, p < 0.0005; 0.276, p = 0.043; 0.181, p = 0.034, respectively). Of three different weight metrics, lean body weight was the most predictive. CONCLUSIONS Female gender and increased body weight explain part of the variance of this adverse effect. Both risk factors offer fresh insights into the pathophysiology of this potentially reversible and dangerous adverse effect of lithium treatment. Future research should focus on understanding the differences between the genders and between different body compositions in terms of lithium pharmacokinetics and pharmacodynamics.

Abstract
AIM Ensuring a seamless transition from child to adult mental health services poses challenges for services worldwide. This is an important process in the ongoing care of young people with mental illness; therefore, it is incumbent on all countries to probe their individual structures to assess the quality of mental health service delivery to this vulnerable cohort. To date, there have been no published studies on the transition from Child to Adult Mental Health Services in the Republic of Ireland. To this end, a nationwide survey of transition policies of community mental health teams in both services was conducted in order to compare best practice guidelines for transition with current process and experience in clinical practice. METHOD Structured interviews were conducted with 57 consultant psychiatrists (representing 32 CAMHS teams and 25 AMHS teams) to obtain information on annual transition numbers, existing transition policies and operational practice from the professional perspective. RESULTS Numbers of young people considered suitable for transfer to adult services (M = 7.73, SD = 9.86, n = 25) were slightly higher than numbers who actually transferred (M = 4.50, SD = 3.33, n = 20). There is a lack of standardized practice nationwide regarding the service transition boundary, an absence of written transition policies and protocols, and minimal formal interaction between child and adult services. CONCLUSIONS The findings suggest that there are critical gaps between current operational practice and best practice guidelines. Future studies will investigate the impact this has on the transition experiences of young people, their carers and health-care professionals.

Abstract
AIMS This study examined the problems encountered by children with autism spectrum disorder (ASD), when accessing dental care. STUDY DESIGN This was a cross-sectional, case-control questionnaire study. METHODS A piloted questionnaire was developed to identify the main barriers to dental care experienced by patients with ASD in Hull and East Riding. The study group was comprised of parents/carers of children with ASD, and the control group was comprised of parents/carers of age matched healthy, neurotypical children. STATISTICS Results were analysed using Chi-square and Fisher's exact tests where appropriate. Significance was deemed at p < 0.05. Ordinal data was presented using medians and 25th and 75th centiles and compared using Mann-Whitney U test. METHODS A piloted questionnaire was developed to identify the main barriers to dental care experienced by patients with ASD in Hull and East Riding. The study group was comprised of parents/carers of children with ASD, and the control group was comprised of parents/carers of age matched healthy, neurotypical children. RESULTS 112 subjects completed the questionnaire. There was no significant difference in accessing dental care between study and control groups (p = 0.051), although access was perceived as more difficult in the ASD group (p < 0.001). There was a significantly greater perceived difficulty in travelling to the dental surgery in the ASD group. Predicted negative behaviours were more frequent in the ASD group. All suggested interventions were predicted to be helpful in a significantly greater proportion of the ASD group. CONCLUSION Difficulties exist for children with ASD in accessing dental care in the Hull and East Riding area.

Abstract
QUESTION Is electrical stimulation and splinting more effective than splinting alone for the management of wrist contracture following acquired brain injury? DESIGN A multi-centre randomised trial with concealed allocation, assessor blinding, and intention-to-treat analysis. PARTICIPANTS Thirty-six adults with first stroke or traumatic brain injury and mild to moderate wrist flexion contractures. INTERVENTION The experimental group received electrical stimulation to the wrist and finger extensor muscles for 1 hour a day over 4 weeks while the control group did not. Both groups wore a splint for 12 hours a day during this 4-week period. OUTCOME MEASURES The primary outcome was passive wrist extension measured with a 3Nm torque and with the fingers in extension. Secondary outcomes included passive wrist extension, wrist and finger extensor strength, wrist flexor spasticity, motor control of the hand, and Global Perceived Effect of Treatment, and perception of treatment credibility. Outcome measures were taken at baseline, at the end of the intervention period (4 weeks), and after a 2-week follow-up period (6 weeks). RESULTS At 4 and 6 weeks, the mean between-group difference (95% CI) for passive wrist extension was 7 degrees (-2 to 15) and -3 degrees (-13 to 7), respectively. Secondary outcomes were statistically non-significant or were of borderline statistical significance. CONCLUSION It is not clear whether electrical stimulation and splinting is more effective than splinting alone for the management of wrist contracture after acquired brain injury. Therapists' confidence in the efficacy of electrical stimulation for contracture management is not yet justified.

Abstract
BACKGROUND Cystic hygroma (CH) is a congenital malformation of the lymphatic system. It most commonly presents in the neck, and aetiological factors include environmental and genetic factors. CASE REPORT A 13-year-old female presented with spontaneous dental pain affecting the maxillary left first and second permanent molar teeth. Medical history revealed a history of left sided cervico-facial-thoracic CH. She was diagnosed with periapical peridontitis and required extraction of both teeth. Clinical management was compromised by the CH involving the left face, neck, ear, tongue, larynx, oropharynx and mediastinum and circling the trachea and great vessels. TREATMENT Initial management included the placement of obtundant dressings for teeth number 26 and 27 with resolution of dental pain. Intensive prevention was instigated, and teeth number 16 and 17 were restored with composite resin under local analgesia (LA) without incident. Extraction of teeth number 26 and 27 was complicated by significant trismus and the unacceptably high risk associated with general anaesthesia, due to intubation difficulties. It proved impossible to achieve satisfactory local analgesia. Due to her difficult airway, it was decided to treat the patient with inhalational sedation, but administered in an operating theatre by a consultant anaesthetist, and teeth were extracted using articaine LA. FOLLOW-UP The patient coped well with this treatment, and was discharged home on the same day. Two year follow-up with intensive prevention showed improved oral health, with no new carious lesions detected. CONCLUSION This is the first report to our knowledge describing dental extractions in the immediate vicinity of a cystic hygroma. A potential management strategy and the difficulties of conventional methods in such patients are discussed.

Abstract
QUESTIONS Can circuit class therapy provide sufficient exercise dosage (at least 20 minutes at ≥ 50% heart rate reserve or total caloric expenditure ≥ 300 kilocalories) to induce a cardiorespiratory fitness effect in adults with traumatic brain injury? Can feedback from heart rate monitors influence exercise intensity? DESIGN Randomised controlled trial within an observational study. PARTICIPANTS Fifty-three people with severe traumatic brain injury, of whom 40 progressed into the trial. INTERVENTION All participants undertook circuit class therapy. Participants allocated to the experimental group received exercise intensity feedback from a heart rate monitor and the control group received no feedback. OUTCOME MEASURES Proportion of participants exercising at ≥ 50% heart rate reserve for at least 20 minutes or expending ≥ 300 kilocalories during circuit class therapy. The primary outcome measure for the trial was the time spent in the heart rate training zone (ie, at ≥ 50% heart rate reserve) during the intervention and re-assessment periods. RESULTS Circuit class therapy provided sufficient cardiorespiratory exercise dosage for 28% (95% CI 18 to 42) of the cohort according to the heart rate reserve criteria and 62% (95% CI 49 to 74) according to the caloric criteria. Feedback did not increase the time in the training zone during the intervention (mean difference 4.8 minutes, 95% CI -1.4 to 10.9) or re-assessment (1.9 minutes, -4.4 to 8.3) periods. CONCLUSION The low intensity, long duration structure of circuit class therapy can provide sufficient exercise dosage for a fitness training effect for 62% of people with traumatic brain injury. Feedback from heart rate monitors does not necessarily influence exercise intensity. TRIAL REGISTRATION ACTRN12607000522415.

Abstract
BACKGROUND Many patients with schizophrenia suffer from poor social functioning, with high levels of unemployment being one particular consequence. Negative symptoms tend to persist during periods of clinical stability and may have a detrimental effect on function. This paper aims to investigate the relationship between negative symptoms and ability to function. METHODS The EGOFORS study measured negative symptoms in 295 schizophrenia patients in 11 European sites using the PANSS Negative Subscale and assessment scales for psychosocial function: Global Assessment of Functioning (GAF), Personal and Social Performance (PSP), Quality of Life Scale (QLS), Functional Remission of General Schizophrenia (FROGS), Psychosocial Remission in Schizophrenia (PSRS) and Subjective Wellbeing under Neuroleptics (SWN). The relationships between the PANSS Negative Subscale and the functional scales were investigated, adjusting for differences between study sites. Being in work, duration of illness, age of onset and number of years of education were also investigated for a relationship with function. RESULTS There were strong, statistically significant correlations between PANSS Negative Subscale and all of the function scales (95% confidence intervals for the correlation coefficients: PSRS 0.77-0.91; FROGS 0.74-0.89; QLS 0.74-0.92; GAF 0.64-0.78; PSP 0.63-0.80) except the SWN. All of the functional scales except SWN were at least moderately related to one another. All of the items in each of the PANSS Negative Subscale and the function scales contributed to the relationships between them. Better functioning correlated strongly with participants being in work. CONCLUSION This study shows a strong and significant relationship between negative symptoms and psychosocial functioning. Given the impact of negative symptoms on psychosocial function, much more emphasis should be placed on developing effective treatments for negative symptoms, given that most patients with schizophrenia now live in community settings and require to function adequately to support their quality of life.

Seasonal influenza vaccination and the risk of infection with pandemic influenza: a possible illustration of non-specific temporary immunity following infection. Euro Surveill 2010; 15.

Abstract
Four Canadian studies have suggested that receipt of seasonal influenza vaccine increased the risk of laboratory-confirmed infection with 2009 pandemic influenza A(H1N1). During the influenza season of 2009 in Victoria, Australia, this virus comprised 97% of all circulating influenza viruses for which sub-typing was available. We found no evidence that seasonal influenza vaccine increased the risk of, or provided protection against, infection with the pandemic virus. Ferret experiments have suggested protection against pandemic influenza A(H1N1) 2009 from multiple prior seasonal influenza infections but not from prior seasonal vaccination. Modelling studies suggest that influenza infection leads to heterosubtypic temporary immunity which is initially almost complete. We suggest these observations together can explain the apparent discrepant findings in Canada and Victoria. In Victoria there was no recent prior circulation of seasonal influenza and thus no temporary immunity to pandemic influenza. There was no association of seasonal influenza vaccine with pandemic influenza infection. In Canada seasonal influenza preceded circulation of the pandemic virus. An unvaccinated proportion of the population developed temporary immunity to pandemic influenza from seasonal infection but a proportion of vaccinated members of the population did not get seasonal infection and hence did not develop temporary immunity to pandemic influenza. It may therefore have appeared as if seasonal vaccination increased the risk of infection with pandemic influenza A(H1N1) virus.

Abstract
Sarcoidosis is a terrific mimicker and can present in many different ways. The case of a middle-aged woman with Crohn's disease who attended the gastroenterology clinic for routine follow-up is presented. She had dry cough and breathlessness for a few weeks. A chest x-ray showed scattered multiple bilateral pulmonary micronodules. This finding on her chest x-ray posed a diagnostic challenge, especially in view of the fact that she was previously treated with immunosuppressants to control her Crohn's disease. A diagnosis of sarcoidosis was established by various tests including lung biopsy, which showed non-caseating granulomas. Within a few weeks of beginning systemic steroid treatment, improvement was noticed in symptoms and lung function tests.

Abstract
Hyperthermia, as an independent modality or in combination with standard cancer treatments such as chemotherapy and radiation, has been established in vitro and in vivo as an effective cancer treatment. However, despite efforts over the past 25 years, such therapies have never been optimized or widely-accepted clinically. Although methods continue to improve, conventionally-delivered heat (RF, ultrasound, microwave etc) can not be delivered in a tumor selective manner. The development of antibody-targeted, or even nontargeted, biocompatible iron oxide nanoparticles (IONP) now allows delivery of cytotoxic heat to individual cancer cells. Using a murine mouse mammary adenocarcinoma (MTGB) and human colon carcinoma (HT29) cells, we studied the biology and treatment of IONP hyperthermia tumor treatment. METHODS Cancer cells (1 × 106) with or without iron oxide nanoparticles (IONP) were studied in culture or in vivo via implanted subcutaneously in female C3H mice, Tumors were grown to a treatment size of 150 mm3 and tumors volumes were measured using standard 3-D caliper measurement techniques. Mouse tumors were heated via delivery of an alternating magnetic field, which activated the nanoparticles, using a cooled 36 mm diameter square copper tube induction coil which provided optimal heating in 1.5 cm wide region of the coil. The IONPs were dextran coated and had a hydrodynamic radius of approximately 100 nm. For the in vivo studies, intra-tumor, peritumor and rectal (core body) temperatures were continually measured throughout the treatment period. RESULTS Although some eddy current heating was generated in non-target tissues at the higher field strengths, our preliminary IONP hyperthermia studies show that whole mouse AMF exposure @160 KHz and 400 or 550 Oe, for a 20 minutes (heat-up and protocol heating), provides a safe and efficacious tumor treatment. Initial electron and light microscopic studies (in vitro and in vivo) showed the 100 nm used in our studies are rapidly taken up and retained by the tumor cells. Additional in vitro studies suggest antibodies can significantly enhance the cellular uptake of IONPs.
