Retaining dermatology patients in primary care through dialogue with secondary care providers: A service evaluation

BACKGROUND

There are long patient waiting lists for specialist care. A dermatology dialogue service between primary and secondary care (DDPS) was developed in eastern England. Primary care referrers uploaded patient images of skin conditions for review by and dialogue with consultant dermatologists in an attempt to retain patients in primary care rather than refer them to secondary care.

METHODS

Evaluation of service performance against specific targets, including reduction in secondary care waiting list growth over the period April 2021-March 2022 inclusive. Service activity was summarized in terms of speed of resolution, case numbers, and dispositions. Clinician and patient satisfaction were assessed using structured questionnaires. Actual numbers of new referrals were compared to projections based on historical data. Waiting list growth was compared to other specialties and other commissioning areas. Waiting times to initial treatment were monitored.

RESULTS

Over 3300 patients were enrolled and > 90% of dialogues were resolved within 36 hours. Clinician and patient satisfaction were high. Frequently asked questions and conditions were highlighted by dermatologists to design and deliver an educational event for primary care clinicians that was well received. Waiting list growth for dermatology patients in the commissioning area was smaller than for other major specialties, and generally smaller than growth for dermatology waiting lists commissioned by other NHS commissioners. There was no negative impact on the urgent priority (cancer pathway) waiting list.

CONCLUSION

The DDPS was satisfactory for clinicians and patients and coincided with lower growth in dermatology waiting lists than might otherwise have been expected.

1230 PALLIATIVE CARE MOVEMENT DISORDERS MULTIDISCIPLINARY MEETING

Introduction

It is well recognised that patients with Parkinson’s disease (PD) have significant symptom burden in advanced stages of their disease. Integration of movement disorder and palliative care services has been limited by concerns about resource and sustainability. We present our experience of establishing a movement disorders palliative care multidisciplinary meeting.

Method

In 2019 we established a multidisciplinary virtual bimonthly meeting between movement disorders and palliative care specialists. Referrals were accepted from movement disorder specialists, community Parkinson’s practitioners and palliative care specialists. Referring clinicians all actively applied primary palliative care approaches within their existing services. Aims of the meeting were to facilitate holistic management of complex needs, support advance care planning (ACP) and consider referral to specialist palliative care services.

Result

37 patients in total were discussed over a 2-year period (although the service was limited for a time due to COVID pressures). On average 3 new patients were discussed per meeting. Reasons for referral included motor and non-motor symptoms, support with ACP, medication advice, caregiver concerns and emotional distress. Meeting outcomes included medication adjustments, expediting reviews, hospice support, carer support, and referral to other services. Since the meetings started 23 (62%) patients have died. Of these, 30% died in hospital compared with the national average of 43.4%. The average between discussion at the meeting and death was 139 days. The meeting has generated education opportunities, triggered joint assessments and a professionals’ framework for the palliative management of patients with a movement disorder.

Conclusions

We present the experience of an MDT embedded within an early integrated palliative care service for movement disorders. The MDT has strengthened partnership working and findings suggest that alongside active primary palliative care, specialist palliative care for PD can be sustainable and resource efficient in a UK setting.

630 Hailey-Hailey Disease: A Rare Presentation in the Hypopharnyx

Background

Hailey-Hailey disease or familial benign pemphigus is a rare genetic blistering skin disease due to mutation of the ATP2C1 gene inherited in autosomal dominant fashion. Prevalence is around 1 in 50,000 and positive family history is observed in 75% of cases. Patients typically present with well-demarcated painful erosive and yellow-crusted rash in the skin folds, following a relapsing-remitting pattern. There are very limited known cases of extra-dermatological presentation of this disease.

Case

64-year-old gentleman presented with dysphagia, hoarseness, sore throat, dry cough, and intermittent haemoptysis. Initial flexible nasendoscopy showed mild erythema of epiglottis and false cords, post-cricoid oedema and very mild Reinke's oedema. He was treated as acid reflux with omeprazole but to little effect. Endoscopy 4 months later showed similar findings hence biopsy of the hypopharynx was taken. The sample demonstrated intraepithelial clefting, suspicious of intraepithelial vesiculobullous disorder particularly pemphigus vulgaris.

Looking into this gentleman's medical history, it was found that he is under the care of dermatology for Hailey-Hailey disease, which he was diagnosed 30 years ago. He also has a strong family history of this condition. Based on the biopsy findings and patient profile, it was concluded that this gentleman has a hypopharyngeal manifestation of Hailey-Hailey disease.

Discussion

Hailey-Hailey disease is traditionally described as a dermatological condition. This gentleman is one of the rare few cases of non-dermatological manifestation of this disease.

A systematic scoping review of early interventions for parents of deaf infants

Background

Over 90% of the 50,000 deaf children in the UK have hearing parents, many of whom were not expecting a deaf child and may require specialist support. Deaf children can experience poorer long-term outcomes than hearing children across a range of domains. After early detection by the Universal Newborn Hearing Screening Programme, parents in the UK receive support from Qualified Teachers of the Deaf and audiologists but resources are tight and intervention support can vary by locality. There are challenges faced due to a lack of clarity around what specific parenting support interventions are most helpful.

Methods

The aim of this research was to complete a systematic scoping review of the evidence to identify early support interventions for parents of deaf infants. From 5577 identified records, 54 met inclusion criteria. Two reviewers screened papers through three rounds before completing data extraction and quality assessment.

Results

Identified parent support interventions included both group and individual sessions in various settings (including online). They were led by a range of professionals and targeted various outcomes. Internationally there were only five randomised controlled trials. Other designs included non-randomised comparison groups, pre / post and other designs e.g. longitudinal, qualitative and case studies. Quality assessment showed few high quality studies with most having some concerns over risk of bias.

Conclusion

Interventions commonly focused on infant language and communication followed by parental knowledge and skills; parent wellbeing and empowerment; and parent/child relationship. There were no interventions that focused specifically on parent support to understand or nurture child socio-emotional development despite this being a well-established area of poor outcome for deaf children. There were few UK studies and research generally was not of high quality. Many studies were not recent and so not in the context of recent healthcare advances. Further research in this area is urgently needed to help develop evidence based early interventions.

1068 Cranial Fasciitis of the Temporal Bone

We present the case of a child with a rare benign tumour of the temporal bone.

A nine-month-old girl was referred to her local paediatric hospital with a painless right-sided, post-auricular swelling increasing in size in the preceding two months. On examination there was a 2x2cm mass overlying the temporal bone posterior to the right ear. The mass was firm, immobile, non-tender and well circumscribed. Ultrasound demonstrated a 1.9cm subcuticular mass with evidence of intracranial extension through the suture. Vascular flow and hyperechoic foci were demonstrated within the lesion. The local paediatric team requested magnetic resonance imaging (MRI) and computed tomography (CT) of temporal bone prior to referral to tertiary care centre. Imaging displayed a 2cm expansile lesion of the temporal bone with cortical loss and effacement of underlying dural venous sinus. The patient proceeded to incisional biopsy for tissue diagnosis which was suggestive of cranial fasciitis. Following discussion at the regional multidisciplinary meeting, she underwent surgical excision of the tumour in a joint Neurosurgery/Otology case. The tumour was fully resected macroscopically, with the normal surrounding bone and mastoid air cells preserved. Final histopathology showed a highly cellular lesion composed of spindle cells arranged in fascicles, with areas of myxoid background and confirmed the tumour to be cranial fasciitis. The child has made a good recovery and will be kept under close clinical follow-up. This case demonstrates a rare benign tumour of the temporal bone that may present to an otolaryngologist and the importance of tissue diagnosis, imaging and multidisciplinary management.

The effect of the COVID-19 pandemic on non-elective otolaryngology admissions and a positive change in clinical practice

As the COVID-19 pandemic progressed across the UK and Northern Ireland in March 2020, our otolaryngology department began to make preparations and changes in practice to accommodate for potentially large numbers of patients with COVID-19 related respiratory illness in the hospital. We retrospectively reviewed the number of non-elective admissions to our department between the months of January and May in 2019 and 2020. A significant reduction in admissions of up to 94% during the months of the pandemic was observed. Our practice shifted to manage patients with epistaxis and peritonsillar abscess on an outpatient basis, and while prospectively collecting data on this, we did not observe any significant adverse events. We view this as a positive learning point and change in our practice as a result of the COVID-19 pandemic.

Change in a clinical measure of cervical movement sense following four weeks of kinematic training

BACKGROUND

Training targeted towards improving cervical movement accuracy is an effective strategy in the management of neck pain. Relatively complex measures have been validated to measure this in research although a simple clinical measure using a head mounted laser tracing a standardised pattern has been shown to be reliable. It is not known if this method demonstrate clinically meaningful change to training.

OBJECTIVE

To assess change responsiveness of the clinical cervical movement sense (CCMS) test following home kinematic training (KT).

STUDY DESIGN

Pre-post treatment observational study.

METHODS

The CCMS measure was assessed in 56 patients with chronic neck pain (41 intervention, 15 control) at baseline and 4 weeks post intervention by blinded assessors. Task completion time and error number were assessed reviewing video of the performances. Change pre-post intervention was compared between groups.

RESULTS

There was a significantly greater mean improvement in the intervention (-9.2 ± 9.3) seconds) for completion time and combined time and error (-13.3 ± 16) compared to the control group for time (-2.0 ± 9.8) and combined time and error (-1.8 ± 14) with moderate to high effect sizes (Cohen's d 0.76). There was a non-significant trend for decreased number of errors in the intervention (-4.1 ± 9.0) compared to control group (0.2 ± 8.3).

CONCLUSION

Completion time of the CCMS test appears to be able to demonstrate meaningful change following four weeks of KT. This further supports its clinical utility as a measure of cervical movement accuracy and provides direction for future clinical use.

A tool to evaluate proportionality and necessity in the use of restrictive practices in forensic mental health settings: the DRILL tool (Dundrum restriction, intrusion and liberty ladders)

BACKGROUND

Prevention of violence due to severe mental disorders in psychiatric hospitals may require intrusive, restrictive and coercive therapeutic practices. Research concerning appropriate use of such interventions is limited by lack of a system for description and measurement. We set out to devise and validate a tool for clinicians and secure hospitals to assess necessity and proportionality between imminent violence and restrictive practices including de-escalation, seclusion, restraint, forced medication and others.

METHODS

In this retrospective observational cohort study, 28 patients on a 12 bed male admissions unit in a secure psychiatric hospital were assessed daily for six months. Data on adverse incidents were collected from case notes, incident registers and legal registers. Using the functional assessment sequence of antecedents, behaviours and consequences (A, B, C) we devised and applied a multivariate framework of structured professional assessment tools, common adverse incidents and preventive clinical interventions to develop a tool to analyse clinical practice. We validated by testing assumptions regarding the use of restrictive and intrusive practices in the prevention of violence in hospital. We aimed to provide a system for measuring contextual and individual factors contributing to adverse events and to assess whether the measured seriousness of threating and violent behaviours is proportionate to the degree of restrictive interventions used. General Estimating Equations tested preliminary models of contexts, decisions and pathways to interventions.

RESULTS

A system for measuring adverse behaviours and restrictive, intrusive interventions for prevention had good internal consistency. Interventions were proportionate to seriousness of harmful behaviours. A 'Pareto' group of patients (5/28) were responsible for the majority (80%) of adverse events, outcomes and interventions. The seriousness of the precipitating events correlated with the degree of restrictions utilised to safely manage or treat such behaviours.

CONCLUSION

Observational scales can be used for restrictive, intrusive or coercive practices in psychiatry even though these involve interrelated complex sequences of interactions. The DRILL tool has been validated to assess the necessity and demonstrate proportionality of restrictive practices. This tool will be of benefit to services when reviewing practices internally, for mandatory external reviewing bodies and for future clinical research paradigms.

A Tasmanian devil breeding program to support wild recovery

Tasmanian devils are threatened in the wild by devil facial tumour disease: a transmissible cancer with a high fatality rate. In response, the Save the Tasmanian Devil Program (STDP) established an 'insurance population' to enable the preservation of genetic diversity and natural behaviours of devils. This breeding program includes a range of institutions and facilities, from zoo-based intensive enclosures to larger, more natural environments, and a strategic approach has been required to capture and maintain genetic diversity, natural behaviours and to ensure reproductive success. Laboratory-based research, particularly genetics, in tandem with adaptive management has helped the STDP reach its goals, and has directly contributed to the conservation of the species in the wild. Here we review this work and show that the Tasmanian devil breeding program is a powerful example of how genetic research can be used to understand and improve reproductive success in a threatened species.

Autism Spectrum Social Stories In Schools Trial 2 (ASSSIST2): study protocol for a randomised controlled trial analysing clinical and cost-effectiveness of Social Stories™ in primary schools

Background

Interventions designed to support children with a diagnosis of Autism Spectrum Conditions (ASC) can be time consuming, needing involvement of outside experts. Social Stories™ are a highly personalised intervention aiming to give children with ASC social information or describing an otherwise difficult situation or skill. This can be delivered daily by staff in education settings. Studies examining Social Story™ use have yielded mostly positive results but have largely been single case studies with a lack of randomised controlled trials (RCTs). Despite this numerous schools are utilising Social Stories™, and a fully powered RCT is timely.

Methods

A multi-site pragmatic cluster RCT comparing care as usual with Social Stories™ and care as usual. This study will recruit 278 participants (aged 4–11) with a clinical diagnosis of ASC, currently attending primary school in the North of England. Approximately 278 school based staff will be recruited to provide school based information about participating children with approximately 140 recruited to deliver the intervention. The study will be cluster randomised by school. Potential participants will be screened for eligibility prior to giving informed consent. Follow up data will be collected at 6 weeks and 6 months post randomisation and will assess changes in participants’ social responsiveness, goal based outcomes, social and emotional health. The primary outcome measure is the Social Responsiveness Scale Second Edition (SRS-2) completed by school based staff at 6 months. Approvals have been obtained from the University of York’s Research Governance Committee, Research Ethics Committee and the Health Research Authority. Study results will be submitted for publication in peer-reviewed journals and disseminated to participating families, educational staff, local authority representatives, community groups and Patient and Participant Involvement representatives. Suggestions will be made to NICE about treatment evidence dependent on findings.

Discussion

This study addresses a much used but currently under researched intervention and results will inform school based support for primary school children with a diagnosis of ASC.

Trial registration

The trial is registered on the ISRCTN registry (registration number: ISRCTN11634810). The trial was retrospectively registered on 23rd April 2019.

Ice therapy: cool, current and complicated

This is the fourth Capsule review article provided by the WSAVA Global Pain Council and which discusses the use of ice or cold therapy as a non-pharmacologic modality for pain control in small animal practice. The physiological effects of cold therapy on tissues, receptors and ion channels are discussed; as well as indications, recommendations for, and limitations of use.

Effects of epigenetic pathway inhibitors on corticotroph tumour AtT20 cells

Medical treatments for corticotrophinomas are limited, and we therefore investigated the effects of epigenetic modulators, a new class of anti-tumour drugs, on the murine adrenocorticotropic hormone (ACTH)-secreting corticotrophinoma cell line AtT20. We found that AtT20 cells express members of the bromo and extra-terminal (BET) protein family, which bind acetylated histones, and therefore, studied the anti-proliferative and pro-apoptotic effects of two BET inhibitors, referred to as (+)-JQ1 (JQ1) and PFI-1, using CellTiter Blue and Caspase Glo assays, respectively. JQ1 and PFI-1 significantly decreased proliferation by 95% (P < 0.0005) and 43% (P < 0.0005), respectively, but only JQ1 significantly increased apoptosis by >50-fold (P < 0.0005), when compared to untreated control cells. The anti-proliferative effects of JQ1 and PFI-1 remained for 96 h after removal of the respective compound. JQ1, but not PFI-1, affected the cell cycle, as assessed by propidium iodide staining and flow cytometry, and resulted in a higher number of AtT20 cells in the sub G1 phase. RNA-sequence analysis, which was confirmed by qRT-PCR and Western blot analyses, revealed that JQ1 treatment significantly altered expression of genes involved in apoptosis, such as NFκB, and the somatostatin receptor 2 (SSTR2) anti-proliferative signalling pathway, including SSTR2. JQ1 treatment also significantly reduced transcription and protein expression of the ACTH precursor pro-opiomelanocortin (POMC) and ACTH secretion by AtT20 cells. Thus, JQ1 treatment has anti-proliferative and pro-apoptotic effects on AtT20 cells and reduces ACTH secretion, thereby indicating that BET inhibition may provide a novel approach for treatment of corticotrophinomas.

Intraperitoneal and incisional analgesia in small animals: simple, cost-effective techniques

The World Small Animal Veterinary Association Global Pain Council (WSAVA-GPC) has recently published its first "capsule review" by Monteiro et al. These are short articles that present a brief assessment of the scientific evidence and practical recommendations on important, and sometimes controversial, subjects in pain management. The capsules will be published regularly in the Journal of Small Animal Practice, the official journal of the WSAVA. This second article discusses the use of intraperitoneal and incisional analgesia in small animal practice, including their limitations and recommendations by the authors.

Quality assurance of rifampicin-containing fixed-drug combinations in South Africa: dosing implications

SETTING:

Rifampicin (RMP) drives treatment response in drug-susceptible tuberculosis. Low RMP concentrations increase the risk of poor outcomes, and drug quality needs to be excluded as a contributor to low RMP exposure.

OBJECTIVES AND DESIGN:

We performed an open-label, three-way cross-over study of three licensed RMP-containing formulations widely used in South Africa to evaluate the bioavailability of RMP in a two-drug fixed-dose combination tablet (2FDC) and a four-drug FDC (4FDC) against a single-drug reference. RMP dosed at 600 mg was administered 2 weeks apart in random sequence. Plasma RMP concentrations were measured pre-dose and 1, 2, 3, 4, 6, 8 and 12 h post-dose. The area under the concentration-time curve (AUC_0–12) of the FDCs was compared to the single drug reference. Simulations were used to predict the impact of our findings.

RESULTS:

Twenty healthy volunteers (median age 22.8 years, body mass index 24.2 kg/m²) completed the study. The AUC_0–12 of the 4FDC/reference (geometric mean ratio [GMR] 78%, 90%CI 69–89) indicated an average 20% reduction in RMP bioavailability in the 4FDC. The 2FDC/reference (GMR 104%, 90%CI 97–111) was bioequivalent. Simulations suggested dose adjustments to compensate for the poor bioavailability of RMP with the 4FDC, and revised weight-band doses to prevent systematic underdosing of low-weight patients.

CONCLUSION:

Post-marketing surveillance of in vivo bioavailability of RMP and improved weight band-based dosing are recommended.

Long-term use of non-steroidal anti-inflammatory drugs in cats with chronic kidney disease: from controversy to optimism

This is the first of a series of capsule reviews published by the World Small Animal Veterinary Association - Global Pain Council (WSAVA-GPC). Each of these short articles provides a brisk assessment of the scientific evidence in specific aspects of pain management, including analgesic techniques, recommendations and controversies surrounding their use. In this first capsule review, the scientific evidence available on the long-term use of non-steroidal anti-inflammatory drugs in cats with concomitant chronic pain and chronic kidney disease is discussed.

Dietary Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA) Operate by Different Mechanisms to Modulate Hepatic Steatosis and Hyperinsulemia in fa/fa Zucker Rats

Hepatic steatosis, an early stage of non-alcoholic fatty liver disease, is commonly present in obesity and type 2 diabetes, and is associated with reduced hepatic omega-3 polyunsaturated fatty acid (n3-PUFA) status that impacts on the anti-inflammatory and insulin sensitizing functions of n3-PUFA. Our objective was to directly compare plant- and marine-based n3-PUFA (α-linoleic acid (ALA)), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA)) for their effects on hepatic steatosis, markers of hepatic inflammation and fibrosis, and insulinemia in obese rats. Fa/fa Zucker rats were provided diets containing ALA, EPA, DHA, or linoleic acid (LA, n6-PUFA) for eight weeks and compared to baseline fa/fa rats and lean Zucker rats fed LA-rich diet for eight weeks. Both DHA and EPA groups had liver lipid similar to baseline, however, DHA was more effective than EPA for reducing hepatic fatty acid synthase (FAS), increasing the proportion of smaller lipid droplets, reversing early fibrotic damage, and reducing fasting hyperinsulinemia. EPA was more effective for reducing FoxO1. Dietary ALA did not attenuate hepatic steatosis, most inflammatory markers or FAS. In summary, amongst the n3-PUFA, DHA was the most effective for elevating hepatic DHA levels, and preventing progression of hepatic steatosis via reductions in FAS and a marker of fibrosis.

Psychiatric training – a dangerous pursuit

We performed a review of the international literature, Royal College of Psychiatrists guidelines and Irish legislation concerning psychiatric trainees and their experience of violence. Physical violence in the workplace was reported by 16% of trainees in Ireland and 67% of specialist registrars in the UK; 72% of trainees in Belgium reported verbal violence. Personal characteristics of trainees which increase the risk of experiencing violence are under-researched, although it is observed that the duration of clinical experience seems to be somewhat protective. the advent of community psychiatry brings new risks to trainees. the Royal College of Psychiatrists issued guidelines and reports that are useful in developing facilities and promoting trainee safety. Although legislation provides some protection to trainees, it also places responsibility on them as employees.

'I can't tell my child they are dying'. Helping parents have conversations with their child

This paper explores the challenges of resolving conflicting feelings around talking with a child about their terminal prognosis. When children are left out of such conversations it is usually done with good intent, with a parent wishing to protect their child from anxiety or loss of hope. There is however growing evidence that sensitive, timely, age appropriate information from those with whom children have a good relationship is helpful both for the child and their family. There is no evidence that involving children in sensitive and timely discussions creates significant problems, rather that withholding information may lead to confusion, frustration, distress and anger. The authors discuss ways in which families can be supported to have these significant conversations with their children.

Epigenetic pathway inhibitors represent potential drugs for treating pancreatic and bronchial neuroendocrine tumors

Cancer is associated with alterations in epigenetic mechanisms such as histone modifications and methylation of DNA, and inhibitors targeting epigenetic mechanisms represent a novel class of anti-cancer drugs. Neuroendocrine tumors (NETs) of the pancreas (PNETs) and bronchus (BNETs), which may have 5-year survivals of <50% and as low as 5%, respectively, represent targets for such drugs, as >40% of PNETs and ~35% of BNETs have mutations of the multiple endocrine neoplasia type 1 (MEN1) gene, which encodes menin that modifies histones by interacting with histone methyltransferases. We assessed 9 inhibitors of epigenetic pathways, for their effects on proliferation, by CellTiter Blue assay, and apoptosis, by CaspaseGlo assay, using 1 PNET and 2 BNET cell lines. Two inhibitors, referred to as (+)-JQ1 (JQ1) and PFI-1, targeting the bromo and extra terminal (BET) protein family which bind acetylated histone residues, were most effective in decreasing proliferation (by 40-85%, P<0.001) and increasing apoptosis (by 2-3.6 fold, P<0.001) in all 3 NET cell lines. The anti-proliferative effects of JQ1 and PFI-1 remained present for at least 48 hours after removal of the compound. JQ1, but not PFI-1, had cell cycle effects, assessed by propidium iodide staining and flow cytometry, resulting in increased and decreased proportions of NET cells in G1, and S and G2 phases, respectively. RNA Sequencing analysis revealed that these JQ1 effects were associated with increased histone 2B expression, and likely mediated through altered activity of bromodomain-containing (Brd) proteins. Assessment of JQ1 in vivo, using a pancreatic beta cell-specific conditional Men1 knockout mouse model that develops PNETs, revealed that JQ1 significantly reduced proliferation (by ~50%, P<0.0005), assessed by bromodeoxyuridine incorporation, and increased apoptosis (by ~3 fold, P<0.0005), assessed by terminal deoxynucleotidyl transferase dUTP nick end labelling, of PNETs. Thus, our studies demonstrate that BET protein inhibitors may provide new treatments for NETs.

Family Perceptions and Provision of Analgesia for Acutely Painful Conditions in Children: A Multi-Centred Prospective Survey

BACKGROUND: More than two-thirds of children who present to the emergency department (ED) complain of pain. It is well known that children’s pain is poorly managed in the ED compared to their adult counterparts. With respect to analgesic administration in the ED, discrepancies exist between physician self-report and institutional audit. Patient refusal of analgesia is a likely explanation. There is good evidence that misconceptions and fears about analgesia in children are common among caregivers and may contribute to withholding pain medication. To date, no study has surveyed caregivers presenting the the ED to assess frequency of analgesic administration and reasons for withholding analgesia. We hypothesize that there will be a significant proportion of care-givers and patients that refuse pain medication in the ED. We also hypothesize that there will be a wide range of reasons for refusal. The insight we gain from this study will help nurses, clinical educators, and physicians provide the appropriate information to parents in an effort to target misconceptions and allay fears.

OBJECTIVES: Our objectives were to characterize the degree of care-giver and patient provision of analgesia prior to arrival, refusal of analgesia in the ED, and reasons behind their decision-making process. We hope to identify specific misconceptions, attitudes, or beliefs that impair the optimal provision of analgesia to children in the ED.

DESIGN/METHODS: A novel survey was designed by a focus group using an iterative approach and implemented over a 16-week period across two Canadian tertiary care paediatric EDs. We included a consecutive sample of caregivers of children aged 4-17 years with an acutely painful condition (headache, abdominal pain, injury, otitis, pharyngitis). Caregivers were asked to answer questions covering five domains: (i) demographics, (ii) analgesia prior to arrival (iii) analgesia offered in the ED and reasons for refusal, (iv) perceptions of analgesia, and (v) caregiver satisfaction at discharge. Children were asked to rate their pain on arrival and at discharge. The primary outcome was the frequency of caregiver provision of analgesia prior to arrival and the proportion of caregivers who accept the offer of analgesia offered in the ED.

RESULTS: Three hundred forty-four caregivers completed the survey. The majority were female (269/339, 79%), aged 36 years or older (256/340, 75%) with a post-secondary education (237/336, 71%). Most (309/339, 91%) reported being able to “tell when their child was in pain”. All respondents rated their child’s maximal pain related to the presenting condition as at least a 6/10. With regards to the primary outcome, 229/338 (68%) of caregivers reported that they did not treat their child’s pain prior to arrival in the ED. Of those who did treat their child’s pain, ibuprofen was the most commonly used analgesic (77/112, 69%). The most common reasons for withholding analgesia was a lack of time (80/210, 38%), fear of masking seriousness of child’s condition (49/210, 23%), fear of masking signs and symptoms (48/210, 23%), and a lack of analgesia at home (47/210, 22%). Analgesia was offered to 186/344 (45%) of children in the ED and the majority of caregivers 157/186 (84%) accepted the offer. The most common reason for not accepting analgesia in the ED was child refusal (15/20, 75%). Most, 231/338 (68%) of caregivers felt that their child’s pain was managed well in the ED.

CONCLUSION: This survey of caregiver perceptions surrounding analgesia for children with acutely painful conditions presenting to the pae-diatric ED suggests that most do not treat their child’s pain prior to arrival, despite high levels of pain. Misconceptions surrounding analgesia prior to arrival are common. Despite this, most caregivers accepted analgesia in the ED. Our results suggest that educational strategies should be directed at caregiver awareness of the impact of pain on children and the need for prompt analgesic therapy, even when an ED visit is planned.

Hallucinations and illusions in migraine in children and the Alice in Wonderland Syndrome

DESIGN

A prospective observational study over 1 year.

SETTING

A District General Hospital, and Child and Adolescent Mental Health Department.

PATIENTS

Children aged 8-18 years living in the catchment area of a district hospital service with any type of unexplained hallucinations or illusions associated with or without an established diagnosis of migraine.

RESULTS

The study identified nine children with a combination of migraine and a variety of hallucinations and illusions, including illusions of size, time, colour, body shape, movement and visual and auditory hallucination. An average of 10 symptoms (range 7-15) were reported.

INTERVENTIONS

None.

MAIN OUTCOME MEASURE

None.

CONCLUSIONS

It is important to recognise these symptoms to enable appropriate history taking and diagnosis. These symptoms are common and currently seem to go unrecognised and may pose diagnostic difficulties if onset is before typical migraine headaches occur.

Prospective study of factors influencing conditional discharge from a forensic hospital: the DUNDRUM-3 programme completion and DUNDRUM-4 recovery structured professional judgement instruments and risk

BACKGROUND

We set out to examine whether structured professional judgement instruments DUNDRUM-3 programme completion (D-3) and DUNDRUM-4 recovery (D-4) scales along with measures of risk, mental state and global function could distinguish between those forensic patients detained in a secure forensic hospital (not guilty by reason of insanity or unfit to stand trial) who were subsequently discharged by a mental health review board. We also examined the interaction between these measures and risk, need for therapeutic security and eventual conditional discharge.

METHODS

A naturalistic observational cohort study was carried out for 56 patients newly eligible for conditional discharge. Patients were rated using the D-3, D-4 and other scales including HCR-20, S-RAMM, START, SAPROF, PANSS and GAF and then observed over a period of twenty three months during which they were considered for conditional discharge by an independent Mental Health Review Board.

RESULTS

The D-3 distinguished which patients were subsequently discharged by the Mental Health Review board (AUC = 0.902, p < 0.001) as did the D-4 (AUC = 0.848, p < 0.001). Item to outcome analysis showed each item of the D-3 and D-4 scales performed significantly better than random. The HCR-20 also distinguished those later discharged (AUC = 0.838, p < 0.001) as did the S-RAMM, START, SAPROF, PANSS and GAF. The D-3 and D-4 scores remained significantly lower (better) for those discharged even when corrected for the HCR-20 total score. Item to outcome analyses and logistic regression analysis showed that the strongest antecedents of discharge were the GAF and the DUNDRUM-3 programme completion scores.

CONCLUSIONS

Structured professional judgement instruments should improve the quality, consistency and transparency of clinical recommendations and decision making at mental health review boards. Further research is required to determine whether the DUNDRUM-3 programme completion and DUNDRUM-4 recovery instruments predict those who are or are not recalled or re-offend after conditional discharge.

Inhibition of smooth muscle cell proliferation by adiponectin requires proteolytic conversion to its globular form

Accelerated atherosclerosis is the primary cardiovascular manifestation of diabetes and correlates inversely with levels of circulating adiponectin, an anti-atherosclerotic adipokine that declines in diabetes. We therefore initiated a study to examine the mechanisms by which adiponectin, a hormone released from adipose tissue, influences the proliferation of vascular smooth muscle cells (SMCs). Addition of adiponectin to quiescent porcine coronary artery SMCs increased both protein and DNA synthesis and concurrently activated ERK1/2 and Akt. By contrast, globular adiponectin, a truncated form of this protein, exhibited anti-mitogenic properties as indicated by the inhibition of protein and DNA synthesis in SMCs stimulated with platelet-derived growth factor (PDGF). Whereas globular adiponectin did not stimulate growth-related signal transduction pathways, it was able to block the PDGF-dependent phosphorylation of eukaryotic elongation factor 2 kinase, a regulator of protein synthesis. Proteolysis of adiponectin with trypsin, which produces globular adiponectin, reversed the growth-stimulating actions of the undigested protein. As the existence of globular adiponectin remains controversial, western blotting was used to establish its presence in rat serum. We found that globular adiponectin was detectable in rat serum, but this result was not obtained with all antibodies. The contrasting properties of adiponectin and its globular form with respect to SMC proliferation suggest that protection against atherosclerosis may therefore be mediated, in part, by the level of globular adiponectin.

THE LEPIDOPTERA OF BERMUDA: THEIR FOOD PLANTS, BIOGEOGRAPHY, AND MEANS OF DISPERSAL

The 183 species of Lepidoptera recorded from Bermuda are discussed with respect to their world distribution, origin, long-range dispersal capability, host plants, nomenclature, and the circumstances of their occurrence in Bermuda; most are illustrated. Fifty-nine species are reported from Bermuda for the first time; Oenobotys invinacealis Ferguson (Pyralidae) and Tetanolita mynesalis inaequalis Ferguson (Noctuidae) are described as new. Four new genus–species combinations and four new synonymies are proposed.The Bermuda islands have a distressed fauna dominated by introduced pest species and migrants from the North American mainland and Caribbean Region. About 125 of the 183 recorded species are thought to be established residents; the remainder are assumed to be vagrants. Of approximately 50 resident species identified as probably indigenous, 11 species and three subspecies are endemic, and one of these, Semiothisa ochrifascia (Warren), is believed extinct.All Bermudian Lepidoptera are of American origin except the few introduced Old World species that are nearly cosmopolitan. Like Norfolk Island, Australia, Bermuda has a supersaturated lepidopterous fauna — more recorded species than its land area might support, which can be explained only by a high incidence of migrants and transients. This migratory component is explained relative to long-range movements of the same or congeneric species elsewhere; and hypotheses are proposed concerning the natural history of long-range dispersal in eastern North America and the ability of these moths to reach Bermuda. From a list of 113 species of Lepidoptera identified as frequent south–north migrants on the mainland, 76 are recorded from Bermuda. These include 38 of the 40 best-known cutworm moths of the eastern United States. It is argued that such moths reach Bermuda repeatedly without man's assistance and must regularly travel similar distances in North America.

Conjugated linoleic acid improves blood pressure by increasing adiponectin and endothelial nitric oxide synthase activity

Conjugated linoleic acid (CLA) has been reported to reduce blood pressure in obese insulin-resistant rats, but its mechanism of action has not been identified. The objective of this study was to determine whether CLA isomers can reduce obesity-related hypertension in the fa/fa Zucker rat in relation to adiponectin production and endothelial nitric oxide synthase (eNOS) activation. Obese fa/fa Zucker rats were randomly assigned to one of four groups: (1) cis-9,trans-11-CLA, (2) trans-10,cis-12 (t10,c12)-CLA, (3) control or (4) captopril. After 8 weeks, systolic blood pressure increased 30% in control obese rats. This increase was attenuated 11%-13% in the t10,c12-CLA isomer and captopril groups, respectively. The t10,c12-CLA isomer concurrently elevated adiponectin levels in both plasma and adipose tissue and increased phosphorylated eNOS in adipose tissue as well as the aorta. Although a direct effect of CLA was not observed in cultured endothelial cells, direct adiponectin treatment increased phosphorylation of eNOS. Endothelial nitric oxide synthase phosphorylation was also increased in adipose of fa/fa Zucker rats infused with adiponectin in parallel with improvements in blood pressure. Our results suggest that the t10,c12-CLA isomer attenuates development of obesity-related hypertension, at least in part, by stimulating adiponectin production, which subsequently activates vascular eNOS.

BioWeld® Tube and surgical glue for experimental sutureless venous microanastomosis

Background

The medial wall of mammalian veins is generally thin and fragile compared with the thick muscle seen in arteries. This makes venous microanastomoses time consuming and challenging. This study aimed to determine the feasibility and effectiveness of using the BioWeld® Tube in conjunction with a surgical glue (butyl-2-cyanoacrylate) in performing sutureless venous microanastomoses.

Methods

The feasibility and effectiveness of microvascular anastomoses in a rabbit jugular vein model were investigated in six animals, using the BioWeld® Tube in conjunction with butyl-2-cyanoacrylate surgical glue. Patency and tissue repair mechanisms at the anastomotic site were assessed 1 week after the procedure.

Results

All anastomoses remained patent at 1 week. Muscle necrosis occurred only in areas where the tissue was subject to the fold-and-bond procedure.

Conclusion

The study showed the feasibility and short-term effectiveness of the BioWeld® Tube in facilitating venous anastomoses.

Artery of percheron infarction: imaging patterns and clinical spectrum

BACKGROUND AND PURPOSE

Occlusion of the AOP results in a characteristic pattern of ischemia: bilateral paramedian thalamus with or without midbrain involvement. Although the classic imaging findings are often recognized, only a few small case series and isolated cases of AOP infarction have been reported. The purpose of this study was to characterize the complete imaging spectrum of AOP infarction on the basis of a large series of cases obtained from multiple institutions.

MATERIALS AND METHODS

Imaging and clinical data of 37 patients with AOP infarction from 2000 to 2009 were reviewed retrospectively. The primary imaging criterion for inclusion was an abnormal signal intensity on MR imaging and/or hypoattenuation on CT involving distinct arterial zones of the bilateral paramedian thalami with or without rostral midbrain involvement. Patients were excluded if there was a neoplastic, infectious, or inflammatory etiology.

RESULTS

We identified 4 ischemic patterns of AOP infarction: 1) bilateral paramedian thalamic with midbrain (43%), 2) bilateral paramedian thalamic without midbrain (38%), 3) bilateral paramedian thalamic with anterior thalamus and midbrain (14%), and 4) bilateral paramedian thalamic with anterior thalamus without midbrain (5%). A previously unreported finding (the "V" sign) on FLAIR and DWI sequences was identified in 67% of cases of AOP infarction with midbrain involvement and supports the diagnosis when present.

CONCLUSIONS

The 4 distinct patterns of ischemia identified in our large case series, along with the midbrain V sign, should improve recognition of AOP infarction and assist with the neurologic evaluation and management of patients with thalamic strokes.

Biological response of hepatomas to an extract of Fagopyrum esculentum M. (buckwheat) is not mediated by inositols or rutin

Buckwheat contains d-chiro-inositol (D-CI) and myo-inositol (MI), possible insulin-mimetic compounds; thus, this study investigated the insulin-mimetic activities of a buckwheat concentrate (BWC), D-CI, and MI on insulin signal transduction pathways and glucose uptake with H4IIE rat hepatoma cells. BWC stimulated phosphorylation of p42/44 extracellular-related kinase (p42/44 ERK) and its downstream target, p70(S6K), on Thr(421). In contrast, D-CI, MI, rutin, or its agylcone form, quercetin, did not activate these signal transduction proteins. Phosphorylation of p38 mitogen-activated protein kinase (p38 MAPK), another target of insulin, was also up-regulated upon BWC treatment. The effects of BWC on glucose uptake were subsequently investigated using H4IIE cells. Insulin and D-CI stimulated glucose uptake, whereas BWC inhibited basal and insulin-stimulated glucose uptake. Although results from this work suggest that BWC has insulin-mimetic effects on select protein phosphorylation events in H4IIE cells, D-CI and MI were not the active components responsible for the observed effects. The inhibition of glucose uptake by BWC suggests that buckwheat may affect hepatic glucose metabolism, possibly by inhibiting glucose flux. Furthermore, the fact that D-CI and MI stimulated glucose uptake in H4IIE cells suggests that other compounds are responsible for inhibition of glucose uptake by BWC.

IGF-1 receptor transactivation mediates Src-dependent cortactin phosphorylation in response to angiotensin IIThis article is one of a selection of papers published in a special issue celebrating the 125th anniversary of the Faculty of Medicine at the University of Manitoba

Release of angiotensin II (Ang II) after vascular injury promotes tissue repair by stimulating phenotypic modulation of smooth muscle cells, which enables cell proliferation and migration. This process requires cytoskeleton remodeling, which involves cortactin, a scaffold protein that is phosphorylated by Src kinase in response to Ang II. Since insulin-like growth factor (IGF)-1 receptor transactivation mediates intracellular signals originating from the Ang II type 1 (AT1) receptor in a Src kinase-dependent manner, we examined whether IGF-1 receptor transactivation was also required for cortactin phosphorylation. Treatment of quiescent smooth muscle cells with Ang II resulted in both cortactin phosphorylation and its translocation to the plasma membrane. Both events were prevented by 1-(1,1-dimethylethyl)-1-(4-methylphenyl)-1H-pyrazolo(3,4-d)pyrimidin-4-amine (PP1), a Src kinase inhibitor, and by AG1024, an inhibitor of the IGF-1 receptor tyrosine kinase. Additionally, PP1 and AG1024 blocked the association of cortactin with actin-related protein (Arp) 3, an actin nucleation factor. These results indicate that Src kinase and the IGF-1 receptor kinase are necessary for activating cortactin. Phosphorylation of Src kinase in Ang II-treated cells was subsequently examined and was shown to be prevented by AG1024. Furthermore, Src kinase phosphorylation was blocked by inhibitors of protein kinase C (PKC), but not by inhibitors of phosphatidylinositol (PI) 3-kinase. These data establish that IGF-1 receptor transactivation is required for Src kinase-mediated cortactin phosphorylation and cytoskeletal reorganization in response to Ang II.

Are there more bowel symptoms in children with autism compared to normal children and children with other developmental and neurological disorders?: A case control study

There is considerable controversy as to whether there is an association between bowel disorders and autism. Using a bowel symptom questionnaire we compared 51 children with autism spectrum disorder with control groups of 35 children from special school and 112 from mainstream school. There was a significant difference in the reporting of certain bowel symptoms (constipation, diarrhoea, flatulence) and food faddiness between the autism group and the mainstream school control group. There was no significant difference between the autism group and children in the special schools except for faddiness, which is an autism specific symptom and not a bowel symptom. This study confirms previously reported findings of an increase in bowel symptoms in children with autism. It would appear, however, that this is not specifically associated with autism as bowel symptoms were reported in similar frequency to a comparison group of children with other developmental and neurological disorders.
