Treatment, not delivery, of the late preterm and term fetus with supraventricular arrhythmia.

OBJECTIVE: While in-utero treatment of sustained fetal supraventricular arrhythmia (SVA) is standard practice in the previable and preterm fetus, data are limited on best practice for late preterm (34 + 0 to 36 + 6 weeks), early term (37 + 0 to 38 + 6 weeks) and term (> 39 weeks) fetuses with SVA. We reviewed the delivery and postnatal outcomes of fetuses at ≥ 35 weeks of gestation undergoing treatment rather than immediate delivery. METHODS: This was a retrospective case series of fetuses presenting at ≥ 35 weeks of gestation with sustained SVA and treated transplacentally at six institutions between 2012 and 2022. Data were collected on gestational age at presentation and delivery, SVA diagnosis (short ventriculoatrial (VA) tachycardia, long VA tachycardia or atrial flutter), type of antiarrhythmic medication used, interval between treatment and conversion to sinus rhythm and postnatal SVA recurrence. RESULTS: Overall, 37 fetuses presented at a median gestational age of 35.7 (range, 35.0-39.7) weeks with short VA tachycardia (n = 20), long VA tachycardia (n = 7) or atrial flutter (n = 10). Four (11%) fetuses were hydropic. In-utero treatment led to restoration of sinus rhythm in 35 (95%) fetuses at a median of 2 (range, 1-17) days; this included three of the four fetuses with hydrops. Antiarrhythmic medications included flecainide (n = 11), digoxin (n = 7), sotalol (n = 11) and dual therapy (n = 8). Neonates were liveborn at 36-41 weeks via spontaneous vaginal delivery (23/37 (62%)) or Cesarean delivery (14/37 (38%)). Cesarean delivery was indicated for fetal SVA in two fetuses, atrial ectopy or sinus bradycardia in three fetuses and obstetric reasons in nine fetuses that were in sinus rhythm at the time of delivery. Twenty-one (57%) cases were treated for recurrent SVA after birth. CONCLUSION: In-utero treatment of the near term and term (≥ 35-week) SVA fetus is highly successful even in the presence of hydrops, with the majority of cases delivered vaginally closer to term, thereby avoiding unnecessary Cesarean section. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Impact of routine urine cultures on antibiotic usage in those undergoing a routine annual spinal cord injury evaluation.

OBJECTIVE: The Veterans Health Administration (VHA), the largest single provider of spinal cord injury and disorder (SCI/D) care in the United States, currently mandates that every patient receives a screening urine culture during the annual evaluation, a yearly comprehensive history and physical examination. This testing has shown in a small subset of patients to overidentify asymptomatic bacteriuria that is then inappropriately treated with antibiotics. The objective of the current analysis was to assess the association of the annual evaluation on urine testing and antibiotic treatment in a national sample of Veterans with SCI/D. DESIGN/METHOD: A retrospective cohort study using national VHA electronic health record data of Veterans with SCI/D seen between October 1, 2017-September 30, 2019 for their annual evaluation. RESULTS: There were 9447 Veterans with SCI/D who received an annual evaluation; 5088 (54%) had a urine culture obtained. 2910 cultures (57%) were positive; E. coli was the most common organism obtained (12.9% of total urine cultures). Of the patients with positive urine cultures, 386 were prescribed antibiotics within the 7 days after that encounter (13%); of the patients with negative cultures (n = 2178), 121 (6%) were prescribed antibiotics; thus, a positive urine culture was a significant driver of antibiotic use (p < 0.001). CONCLUSION: The urine cultures ordered at the annual exam are often followed by antibiotics; this practice may be an important target for antibiotic stewardship programs in SCI.

Stratification of alopecia areata reveals involvement of CD4 T cell populations and altered faecal microbiota.

Alopecia areata (AA) is an immune-mediated disease that causes non-scarring hair loss. Autoreactive CD8 T cells are key pathogenic effectors in the skin, and AA has been associated both with atopy and with perturbations in intestinal homeostasis. This study aimed to investigate mechanisms driving AA by characterizing the circulating immunophenotype and faecal microbiome, and by stratifying AA to understand how identified signatures associated with heterogeneous clinical features of the condition. Flow cytometric analyses identified alterations in circulating B cells and CD4 T cells, while 16S sequencing identified changes in alpha and beta diversity in the faecal microbiome in AA. The proportions of transitional and naïve B cells were found to be elevated in AA, particularly in AA samples from individuals with >50% hair loss and those with comorbid atopy, which is commonly associated with extensive hair loss. Although significant changes in circulating CD8 T cells were not observed, we found significant changes in CD4+ populations. In individuals with <50% hair loss higher frequencies of CCR6+CD4 ("Th17") and CCR6+CXCR3+CD4 ("Th1/17") T cells were found. While microbial species richness was not altered, AA was associated with reduced evenness and Shannon diversity of the intestinal microbiota, again particularly in those with <50% hair loss. We have identified novel immunological and microbial signatures in individuals with alopecia areata. Surprisingly, these are associated with lower levels of hair loss, and may therefore provide a rationale for improved targeting of molecular therapeutics.

The epidemiology of alopecia areata: a population-based cohort study in UK primary care.

BACKGROUND: There is a lack of population-based information on the disease burden and management of alopecia areata (AA). OBJECTIVES: To describe the epidemiology of AA, focusing on incidence, demographics and patterns of healthcare utilization. METHODS: Population-based cohort study of 4·16 million adults and children, using UK electronic primary care records from the Oxford-Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) network database, 2009-2018. The incidence and point prevalence of AA were estimated. Variation in AA incidence by age, sex, deprivation, geographical distribution and ethnicity was examined. Patterns of healthcare utilization were evaluated in people with incident AA. RESULTS: The AA incidence rate was 0·26 per 1000 person-years. AA point prevalence in 2018 was 0·58% in adults. AA onset peaked at age 25-29 years for both sexes, although the peak was broader in females. People of nonwhite ethnicity were more likely to present with AA, especially those of Asian ethnicity [incidence rate ratio (IRR) 3·32 (95% confidence interval 3·11-3·55)]. Higher AA incidence was associated with social deprivation [IRR most vs. least deprived quintile 1·47 (1·37-1·59)] and urban living [IRR 1·23 (1·14-1·32)]. People of higher social deprivation were less likely to be referred for specialist dermatology review. CONCLUSIONS: By providing the first large-scale estimates of the incidence and point prevalence of AA, our study helps to understand the burden of AA on the population. Understanding the variation in AA onset between different population groups may give insight into the pathogenesis of AA and its management.

Frontal fibrosing alopecia: survey of severity assessment methods in routine clinical practice and validation of the International Frontal Fibrosing Alopecia Cooperative Group measurement guidance.

BACKGROUND: The lack of validated and responsive outcome measures in the management of frontal fibrosing alopecia (FFA) significantly limits assessment of disease progression and treatment response over time. AIM: To understand how FFA extent and progression is currently assessed in UK specialist centres, to validate components of the International FFA Cooperative Group (IFFACG) statement on FFA assessment, and to identify pragmatic advice to improve FFA management in clinic. METHODS: Consultant dermatologists with a specialist interest in hair loss (n = 17) were invited to take part. Preferred FFA assessment methods were explored using questionnaires and clinical scenarios. Participants were asked to identify and mark the current hairline in 10 frontal and 10 temporal hairline images (Questionnaire 1), with assessment repeated 3 months later to assess intraindividual variability (Questionnaire 2) and 12 months later to test whether interindividual accuracy could be improved with simple instruction (Questionnaire 3). RESULTS: All 17 clinicians (100%) completed the questionnaire at each time interval. We identified a wide variation in assessment techniques used by our experts. Measurements were perceived as the most accurate method of assessing frontal recession whereas photography was preferred for temporal recession. Inter-rater reliability between clinicians measuring the frontal hairline scenarios indicated a moderate strength of agreement [intraclass coefficient (ICC) = 0.61; 95% CI 0.40-0.85], yet intrarater reliability was found to be poor with wide limits of agreement (-8.71 mm to 9.92 mm) on follow-up. Importantly, when clear guidance was provided on how the hairline should be identified (Questionnaire 3), inter-rater reliability improved significantly, with ICC = 0.70, suggesting moderate agreement (95% CI 0.51-0.89; P < 0.001). A similar pattern was seen with temporal hairline measurements, which again improved in accuracy with instruction. CONCLUSION: We found that accuracy of measurements in FFA can be improved with simple instruction and we have validated components of the IFFACG measurement recommendations.

The brain and behavioral correlates of motor-related analgesia (MRA).

The human motor system has the capacity to act as an internal form of analgesia. Since the discovery of the potential influence of motor systems on analgesia in rodent models, clinical applications of targeting the motor system for analgesia have been implemented. However, a neurobiological basis for motor activation's effects on analgesia is not well defined. Motor-related analgesia (MRA) is a phenomenon wherein a decrease in pain symptoms can be achieved through either indirect or direct activation of the motor axis. To date, research has focused on (a) evaluating the pain-motor interaction as one focused on the acute protection from painful stimuli; (b) motor cortex stimulation for chronic pain; or (c) exercise as a method of improving chronic pain in animal and human models. This review evaluates (1) current knowledge surrounding how pain interferes with canonical neurological performance throughout the motor axis; and (2) the physiological basis for motor-related analgesia as a means to reduce pain symptom loads for patients. A proposal for future research directions is provided.

Alopecia areata is characterized by dysregulation in systemic type 17 and type 2 cytokines, which may contribute to disease-associated psychological morbidity.

BACKGROUND: Alopecia areata (AA) is a common autoimmune disease, causing patchy hair loss that can progress to involve the entire scalp (totalis) or body (universalis). CD8+ NKG2D+ T cells dominate hair follicle pathogenesis, but the specific mechanisms driving hair loss are not fully understood. OBJECTIVES: To provide a detailed insight into the systemic cytokine signature associated with AA, and to assess the association between cytokines and depression. METHODS: We conducted multiplex analysis of plasma cytokines from patients with AA, patients with psoriatic arthritis (PsA) and healthy controls. We used the Hospital Anxiety and Depression Scale (HADS) to assess the occurrence of depression and anxiety in our cohort. RESULTS: Our analysis identified a systemic inflammatory signature associated with AA, characterized by elevated levels of interleukin (IL)-17A, IL-17F, IL-21 and IL-23 indicative of a type 17 immune response. Circulating levels of the type 2 cytokines IL-33, IL-31 and IL-17E (IL-25) were also significantly increased in AA. In comparison with PsA, AA was associated with higher levels of IL-17F, IL-17E and IL-23. We hypothesized that circulating inflammatory cytokines may contribute to wider comorbidities associated with AA. Our assessment of psychiatric comorbidity in AA using HADS scores showed that 18% and 51% of people with AA experienced symptoms of depression and anxiety, respectively. Using linear regression modelling, we identified that levels of IL-22 and IL-17E are positively and significantly associated with depression. CONCLUSIONS: Our data highlight changes in both type 17 and type 2 cytokines among people with AA, suggesting that complex systemic cytokine profiles may contribute both to the pathogenesis of AA and to the associated depression. What's already known about this topic? NKG2D+ CD8+ T cells cause hair loss in alopecia areata (AA) but the immunological mechanisms underlying the disease are not fully understood. AA is associated with changes in levels of interleukin (IL)-6, tumour necrosis factor-α, IL-1ß and type 17 cytokines. Psychiatric comorbidity is common among people with AA. What does this study add? People with AA have increased plasma levels of the type 2 cytokines IL-33, IL-31 and IL-17E (IL-25), in addition to the type 17 cytokines IL-17A, IL-21, IL-23 and IL-17F. Levels of IL-17E and IL-22 positively predict depression score. What is the translational message? AA is associated with increased levels of multiple inflammatory cytokines, implicating both type 17- and type 2 immune pathways. Our data indicate that therapeutic strategies for treating AA may need to address the underlying type 17- and type 2 immune dysregulation, rather than focusing narrowly on the CD8+ T-cell response. An immunological mechanism might contribute directly to the depression observed in people with AA.

Use of bioengineered human commensal gut bacteria-derived microvesicles for mucosal plague vaccine delivery and immunization.

Plague caused by the Gram-negative bacterium, Yersinia pestis, is still endemic in parts of the world today. Protection against pneumonic plague is essential to prevent the development and spread of epidemics. Despite this, there are currently no licensed plague vaccines in the western world. Here we describe the means of delivering biologically active plague vaccine antigens directly to mucosal sites of plague infection using highly stable microvesicles (outer membrane vesicles; OMVs) that are naturally produced by the abundant and harmless human commensal gut bacterium Bacteroides thetaiotaomicron (Bt). Bt was engineered to express major plague protective antigens in its OMVs, specifically Fraction 1 (F1) in the outer membrane and LcrV (V antigen) in the lumen, for targeted delivery to the gastrointestinal (GI) and respiratory tracts in a non-human primate (NHP) host. Our key findings were that Bt OMVs stably expresses F1 and V plague antigens, particularly the V antigen, in the correct, immunogenic form. When delivered intranasally V-OMVs elicited substantive and specific immune and antibody responses, both in the serum [immunoglobulin (Ig)G] and in the upper and lower respiratory tract (IgA); this included the generation of serum antibodies able to kill plague bacteria. Our results also showed that Bt OMV-based vaccines had many desirable characteristics, including: biosafety and an absence of any adverse effects, pathology or gross alteration of resident microbial communities (microbiotas); high stability and thermo-tolerance; needle-free delivery; intrinsic adjuvanticity; the ability to stimulate both humoral and cell-mediated immune responses; and targeting of primary sites of plague infection.

Zero-Magnetic Field Fractional Quantum States.

Since the discovery of the fractional quantum Hall effect in 1982 there has been considerable theoretical discussion on the possibility of fractional quantization of conductance in the absence of Landau levels formed by a quantizing magnetic field. Although various situations have been theoretically envisaged, particularly lattice models in which band flattening resembles Landau levels, the predicted fractions have never been observed. In this Letter, we show that odd and even denominator fractions can be observed, and manipulated, in the absence of a quantizing magnetic field, when a low-density electron system in a GaAs based one-dimensional quantum wire is allowed to relax in the second dimension. It is suggested that such a relaxation results in formation of a zigzag array of electrons with ring paths which establish a cyclic current and a resultant lowering of energy. The behavior has been observed for both symmetric and asymmetric confinement but increasing the asymmetry of the confinement potential, to result in a flattening of confinement, enhances the appearance of new fractional states. We find that an in-plane magnetic field induces new even denominator fractions possibly indicative of electron pairing. The new quantum states described here have implications both for the physics of low dimensional electron systems and also for quantum technologies. This work will enable further development of structures which are designed to electrostatically manipulate the electrons for the formation of particular configurations. In turn, this could result in a designer tailoring of fractional states to amplify particular properties of importance in future quantum computation.

Urogenital symptoms in mitochondrial disease: overlooked and undertreated.

BACKGROUND AND PURPOSE: Bowel symptoms are well documented in mitochondrial disease. However, data concerning other pelvic organs is limited. A large case-control study has therefore been undertaken to determine the presence of lower urinary tract symptoms (LUTS) and sexual dysfunction in adults with genetically confirmed mitochondrial disease. METHODS: Adults with genetically confirmed mitochondrial disease and control subjects were recruited from a specialist mitochondrial clinic. The presence and severity of LUTS and their impact on quality of life, in addition to sexual dysfunction and bowel symptoms, were captured using four validated questionnaires. Subgroup analysis was undertaken in patients harbouring the m.3243A>G MT-TL1 mitochondrial DNA mutation. A subset of patients underwent urodynamic studies to further characterize their LUTS. RESULTS: Data from 58 patients and 19 controls (gender and age matched) were collected. Adults with mitochondrial disease had significantly more overactive bladder (81.5% vs. 56.3%, P = 0.039) and low stream (34.5% vs. 5.3%, P = 0.013) urinary symptoms than controls. Urodynamic studies in 10 patients confirmed that bladder storage symptoms predominate. Despite high rates of LUTS, none of the patient group was receiving treatment. Female patients and those harbouring the m.3243A>G MT-TL1 mutation experienced significantly more sexual dysfunction than controls (53.1% vs. 11.1%, P = 0.026, and 66.7% vs. 26.3%, P = 0.011, respectively). CONCLUSIONS: Lower urinary tract symptoms are common but undertreated in adult mitochondrial disease, and female patients and those harbouring the m.3243A>G MT-TL1 mutation experience sexual dysfunction. Given their impact on quality of life, screening for and treating LUTS and sexual dysfunction in adults with mitochondrial disease are strongly recommended.

Overcoming the barriers migrants face in accessing health care.

Migrants face many barriers when accessing health care, both structural and political, leading to unmet need and poor quality care. Yet these barriers often can be overcome. This short communication reports a workshop confronting these issues at the First World Congress on Migration, Ethnicity, Race and Health. It explores the structural factors that create barriers and the competencies that health professionals need to overcome them. It then examines how one non-governmental organization did confront, successfully, a restrictive policy adopted in the United Kingdom, through advocacy and practical action. It concludes by examining the related issue of cultural competency, drawing on experiences of a mental health unit in Athens, Greece.

Flow Restoration in the Columbia River Basin: An Evaluation of a Flow Restoration Accounting Framework.

Securing environmental flows in support of freshwater biodiversity is an evolving field of practice. An example of a large-scale program dedicated to restoring environmental flows is the Columbia Basin Water Transactions Program in the Pacific Northwest region of North America, which has been restoring flows in dewatered tributary habitats for imperiled salmon species over the past decade. This paper discusses a four-tiered flow restoration accounting framework for tracking the implementation and impacts of water transactions as an effective tool for adaptive management. The flow restoration accounting framework provides compliance and flow accounting information to monitor transaction efficacy. We review the implementation of the flow restoration accounting framework monitoring framework to demonstrate (a) the extent of water transactions that have been implemented over the past decade, (b) the volumes of restored flow in meeting flow targets for restoring habitat for anadromous fish species, and (c) an example of aquatic habitat enhancement that resulted from Columbia Basin Water Transactions Program investments. Project results show that from 2002 to 2015, the Columbia Basin Water Transactions Program has completed more than 450 water rights transactions, restoring approximately 1.59 million megaliters to date, with an additional 10.98 million megaliters of flow protected for use over the next 100 years. This has resulted in the watering of over 2414 stream kilometers within the Columbia Basin. We conclude with a discussion of the insights gained through the implementation of the flow restoration accounting framework. Understanding the approach and efficacy of a monitoring framework applied across a large river basin can be informative to emerging flow-restoration and adaptive management efforts in areas of conservation concern.

Correlates of treatment satisfaction and well-being among patients with type II diabetes.

AIM: To examine the impact of patient characteristics, anthropometric measurement and patient clinical variables on their appraisal of treatment satisfaction and well-being. BACKGROUND: Treatment satisfaction and well-being are instrumental in achieving diabetes care goals. Nursing practices and healthcare policies may inform interventions in these areas. INTRODUCTION: The prevalence of diabetes is high in the Middle East. An understanding of relationships between clinical and socio-demographic variables and well-being and treatment satisfaction is needed to improve care and patient outcomes. METHODS: A total of 1002 patients completed tools measuring well-being, treatment satisfaction and socio-demographic characteristics. A series of bivariate and multivariate analysis were conducted to identify factors associated with well-being and treatment satisfaction. RESULTS: Males reported better treatment satisfaction and well-being than females. Older participants, those who were compliant to diet, with controlled diabetes, and no neuropathy reported higher treatment satisfaction scores and well-being scores. Insulin therapy was associated with better treatment satisfaction. DISCUSSION: Females, participants who were not prescribed diabetic diets and those with complications were more likely to be negatively impacted by diabetes. Individuals with diabetes who were treated with insulin had higher treatment satisfaction than those who used oral hypoglycaemic agents. CONCLUSION AND IMPLICATION FOR NURSING AND HEALTH POLICY: These findings are important in assisting nurses and other healthcare professionals in identifying patients with diabetes with low treatment satisfaction who may present a greater risk for poor well-being. Additionally, they lend support to developing policies for frequent screenings and special therapeutic interventions that are needed to maximize patients' treatment satisfaction and well-being in the Middle East and elsewhere.

In vivo imaging of brain microglial activity in antipsychotic-free and medicated schizophrenia: a [11C](R)-PK11195 positron emission tomography study.

Positron emission tomography (PET) imaging of the 18 kDa translocator protein (TSPO) has been used to investigate whether microglial activation, an indication of neuroinflammation, is evident in the brain of adults with schizophrenia. Interpretation of these studies is confounded by potential modulatory effects of antipsychotic medication on microglial activity. In the first such study in antipsychotic-free schizophrenia, we have used [11C](R)-PK11195 PET to compare TSPO availability in a predominantly antipsychotic-naive group of moderate-to-severely symptomatic unmedicated patients (n=8), similarly symptomatic medicated patients with schizophrenia taking risperidone or paliperidone by regular intramuscular injection (n=8), and healthy comparison subjects (n=16). We found no evidence for increased TSPO availability in antipsychotic-free patients compared with healthy controls (mean difference 4%, P=0.981). However, TSPO availability was significantly elevated in medicated patients (mean increase 88%, P=0.032) across prefrontal (dorsolateral, ventrolateral, orbital), anterior cingulate and parietal cortical regions. In the patients, TSPO availability was also strongly correlated with negative symptoms measured using the Positive and Negative Syndrome Scale across all the brain regions investigated (r=0.651-0.741). We conclude that the pathophysiology of schizophrenia is not associated with microglial activation in the 2-6 year period following diagnosis. The elevation in the medicated patients may be a direct effect of the antipsychotic, although this study cannot exclude treatment resistance and/or longer illness duration as potential explanations. It also remains to be determined whether it is present only in a subset of patients, represents a pro- or anti-inflammatory state, its association with primary negative symptoms, and whether there are significant differences between antipsychotics.

Retrospective review of diphencyprone in the treatment of alopecia areata.

BACKGROUND: Contact immunotherapy with diphencyprone (DCP) is used to treat alopecia areata (AA). Its reported efficacy is variable, and individual response cannot be predicted. AIM: To identify patient and treatment course variables that may affect treatment outcome, and to review DCP service to identify potential areas for development and improvement. METHODS: This was a retrospective review of a DCP service over a 20-year period (1991-2010). RESULTS: Complete data was available for 205 treatment courses, and 162 (79%) treatment courses were completed for 133 patients. Overall, 72.2% (96/133) of patients had some hair regrowth (any grade). In 15.8% of cases (21/133), response was > 90% regrowth. However, 27.1% (36/133) had no response. We found that extent of alopecia at baseline and duration of disease were statistically significant when comparing patients with an optimal outcome to those without (P < 0.05). In contrast to other reports, atopy, age at onset and nail dystrophy were not statistically significant. For patients receiving more than one course, response to DCP treatment was broadly consistent. CONCLUSIONS: Extent of alopecia at baseline and duration of disease are important factors in predicting response. Our results suggest that atopy should not be considered a predictor of poor outcome with respect to DCP treatment. A need for improved data collection, particularly regarding longer-term outcomes, was identified. The role of maintenance therapy requires objective assessment. Opportunities for DCP self-administration by patients should be explored. Limitations of this study include the retrospective nature of the review and lack of long-term follow-up data.

Macrophages as target cells for Mayaro virus infection: involvement of reactive oxygen species in the inflammatory response during virus replication.

Alphaviruses among the viruses that cause arthritis, consisting in a public health problem worldwide by causing localized outbreaks, as well as large epidemics in humans. Interestingly, while the Old World alphaviruses are arthritogenic, the New World alphaviruses cause encephalitis. One exception is Mayaro virus (MAYV), which circulates exclusively in South America but causes arthralgia and is phylogenetically related to the Old World alphaviruses. Although MAYV-induced arthritis in humans is well documented, the molecular and cellular factors that contribute to its pathogenesis are completely unknown. In this study, we demonstrated for the first time that macrophages, key players in arthritis development, are target cells for MAYV infection, which leads to cell death through apoptosis. We showed that MAYV replication in macrophage induced the expression of TNF, a cytokine that would contribute to pathogenesis of MAYV fever, since TNF promotes an inflammatory profile characteristic of arthritis. We also found a significant increase in the production of reactive oxygen species (ROS) at early times of infection, which coincides with the peak of virus replication and precedes TNF secretion. Treatment of the cells with antioxidant agents just after infection completely abolished TNF secretion, indicating an involvement of ROS in inflammation induced during MAYV infection.

Frontal Fibrosing Alopecia.

Frontal fibrosing alopecia, described just over 20 years ago, has become one of the most frequently seen causes of scarring alopecia at many specialist hair clinics. Considered a clinical variant of lichen planopilaris (LPP), it has distinctive features and associations which distinguish it from LPP. Although largely affecting postmenopausal women, a small but increasing number of men and premenopausal women are affected. The spectrum of the disease has expanded from involvement of the frontal hairline and eyebrows, to potentially affecting the entire hairline, facial and body hair. Genetic and environmental factors have been implicated but the aetiology remains uncertain. A range of treatments have been used in management of the condition, but clinical trials are required to establish effectiveness.

Case finding for chronic obstructive pulmonary disease in people attending long-term condition clinics in primary care.

Despite increased interest and awareness of chronic obstructive pulmonary disease (COPD), nearly half of the people with COPD remain undiagnosed. Inviting people at risk for screening is unlikely to be effective as many will not attend. Co-morbidities are common in people with COPD but COPD is also a comorbidity of other long-term conditions and people with these conditions are under regular review in primary care clinics. This study aimed to develop a pilot programme to case find people with COPD among patients attending other long-term clinics in primary care. Twenty-three general practices were recruited to participate in South West England. All current or ex-smokers aged ≥35 attending a long-term condition clinic who were not known to have COPD were asked to complete a questionnaire designed to help identify people with COPD and to perform microspirometry. Practices were asked to collect data on up to 100 patients. One thousand three hundred and thirty-three patients were assessed. Four hundred and ten people (31%) were current smokers. Six hundred and thirteen (46%) had high questionnaire scores and 287 (22%) of these also had a forced expiratory volume in 1 second (FEV1) below the lower limit of normal (LLN). The mean FEV1 in these patients was 59.0% of predicted (range 22-79.0%). Two hundred and twenty-four had an FEV1 between 50% and 80% of predicted, 50 had an FEV1 between 30% and 50% of predicted. One hundred and sixteen (40%) of the people with an FEV1 below the LLN were still smoking and 55 accepted referral to cessation services. A total of 56% of the other smokers assessed but not thought to have COPD also accepted referral. Assessing symptoms and performing microspirometry in people attending long-term condition clinics in primary care is feasible and has a high yield of identifying people likely to have previously undiagnosed COPD.

Outreach clinical dental education: the Portsmouth experience - a 4-year follow-up study.

BACKGROUND: The Portsmouth Dental Academy (UPDA) was opened in September 2010 and was a development from the highly successful School of Professionals Complementary to Dentistry (2004-2010). The aim of the Academy was to provide integrated team education for all dental professionals in a primary care setting. The dental students are on outreach from King's College London, and the dental care professional students are registered at the University of Portsmouth. OBJECTIVES: To evaluate the dental students response to the residential outreach educational experience at the UPDA. METHODS: A 49-item questionnaire divided into nine domains that provided both qualitative data and quantitative data were administered at the end of the longitudinal 10-week placement, to four successive cohorts of students in 2010-2014. RESULTS: A 95% return rate was achieved. Students valued highly the quality of the clinical teaching. Through their experience, they felt they understood fully the role of the dentist in care planning in primary care and felt well prepared for dental foundation training. This educational success is unpinned with successful maintenance factors including a well-organised induction period and giving the students a sense of belongingness, empowerment and autonomy for their personal development as new graduates. CONCLUSION: Within the limitations of the questionnaire study over the 4-year period, the students were very positive about all the aspects of this residential outreach education at the UPDA but particularly valued the immersion in clinical dentistry and the bridging from dental school to their dental foundation training.

Familial hepatopulmonary syndrome in common variable immunodeficiency.

Common Variable Immunodeficiency (CVID) comprises a heterogeneous group of primary antibody deficiencies which lead to a range of complications, including infectious, neoplastic and inflammatory disorders. This report describes monozygotic twin brothers with CVID who developed cryptogenic liver disease and subsequently hepatopulmonary syndrome (HPS). This is the second report of the association of HPS and CVID. Its occurrence in two identical twins implicates a genetic basis.
