Abstract
HIV-positive gay, bisexual, two-spirit, and other men who have sex with men (MSM) have exhibited significant resilience to HIV/AIDS in Canada since the start of the epidemic. Since 2012, most of the research that has been conducted on resilience to HIV/AIDS has utilized quantitative methods and deficits-based approaches, with a preferential focus on the plight of young MSM. In order to address apparent gaps in research on HIV/AIDS resilience, we conducted a community-based participatory research qualitative study that utilized a strengths-based approach to examine the perspectives and lived experiences of HIV-positive, middle-aged and older MSM on their individual attributes that helped forge their HIV/AIDS resilience. We conducted 41 semistructured interviews with diverse, HIV-positive, middle-aged and older MSM from Central and Southwestern Ontario, Canada. From our thematic analysis of our interviews, we identified four themes, which represented personal strengths that fostered resilience to HIV/AIDS: (a) proactiveness, (b) perseverance, (c) having the right mindset, and (d) self-awareness with self-control. This article discusses the importance of these personal strengths to fostering HIV/AIDS resilience, and how community-based resources could potentially lessen the need to muster such personal strengths, or alternatively, cultivate them.

Abstract
Studies of ectoparasites of wild-caught queenfish Scomberoides commersonnianus from several areas in northern Australia were reviewed to investigate relationships between parasite burdens, environmental conditions and external lesions. A sample of 27 queenfish captured near a dredge spoil disposal site in Gladstone Harbour, Queensland, Australia, in January 2012 was anomalous, with a high percentage of fish (66.6%) exhibiting grossly visible skin lesions including foci of erythema and petechial haemorrhages, particularly on the pectoral girdle and ventrolateral surfaces. Microscopically, lesions comprised acute epidermal erosion, ulceration and/or perivascular dermatitis with dermal oedema and depigmentation. Skin lesions were associated with high prevalence (100%) and intensity (mean = 21.2 copepods fish-1, range 4-46) of infection by sea lice Lepeophtheirus spinifer. Only queenfish infected with >10 L. spinifer presented with skin lesions. This is the first record of L. spinifer from Australia. In contrast, grossly visible skin lesions were not reported from queenfish (n = 152) sampled from other sites in the Northern Territory and Queensland, where the sampled fish had a much lower prevalence (51.3%) and intensity (mean = 3.54, range 0-26) of copepod (L. spinifer, Caligus spp. and Tuxophorus sp.) infections. Copepods from queenfish in studies undertaken outside Gladstone Harbour exhibited an over-dispersed pattern of infection, with the vast majority (n = 137, or 90.1%) of fish infected with <5 copepods. These data demonstrate that heavy L. spinifer infections, combined with poor water quality and/or direct exposure to contaminated dredge spoil and blooms of the cyanobacterium Lyngbya majuscula, can be associated with cutaneous disease in wild-caught queenfish.

Abstract
Abstract
Calorie posting is now policy in hospitals in Ireland and restaurants will be required to display calorie counts on menus by end of 2019. The Health Promotion, Dietetics and Catering teams worked together to introduce calorie posting and a traffic light system (TLS) for all foodstuffs available in the staff canteen of a large University teaching hospital in Dublin, Ireland. A calorie posting launch took place in September 2018. The aim of this study was to determine staff perception of calorie posting and TLS.
One month after the launch, 343 staff members were surveyed using a short pre-designed Sphynx-software questionnaire at 3 time points daily over one week, at breakfast, lunch and evening mealtimes. SPSS was used for analysis.
Of the 353 respondents (65.3% female; 18-44 years 65.3%, 45+ 32.1%, unknown 2.6%), more staff found calorie posting helpful compared to TLS (66.5% vs 43.7%; p = 0.001). Staff stated they made themselves aware of calorie count always/mostly (46%) and sometimes (26.2%). More females than men found both calorie posting (72.3% vs 53.3%; p = 0.001) and TLS (49.1% vs 31.8%; p = 0.001) helpful. More respondents identified calorie posting than TLS as influencing food choice at least sometimes (60.3% vs 36%; p = 0.0001). Females were more likely to make a food choice change based on TLS (39.7 vs 20.6%; p = 0.01). Age and frequency of canteen use were not associated with either.
The results suggest calorie posting is used rather than TLS by all hospital staff and female hospital staff are likelier to use both. Learning from this study, the positioning of TLS in relation to individual foodstuffs has been reviewed, further promotion of TLS/calorie posting has taken place in the hospital and a regular audit has been established. Notwithstanding the challenges, important moves towards healthier choices were seen.
Key messages
Introduction of traffic light system and calorie posting needs evaluation. Females appear more likely to avail of traffic light systems and calorie posting in relation to food choices.

Abstract
The power of citizen science to contribute to both science and society is gaining increased recognition, particularly in physics and biology. Although there is a long history of public engagement in agriculture and food science, the term 'citizen science' has rarely been applied to these efforts. Similarly, in the emerging field of citizen science, most new citizen science projects do not focus on food or agriculture. Here, we convened thought leaders from a broad range of fields related to citizen science, agriculture, and food science to highlight key opportunities for bridging these overlapping yet disconnected communities/fields and identify ways to leverage their respective strengths. Specifically, we show that (i) citizen science projects are addressing many grand challenges facing our food systems, as outlined by the United States National Institute of Food and Agriculture, as well as broader Sustainable Development Goals set by the United Nations Development Programme, (ii) there exist emerging opportunities and unique challenges for citizen science in agriculture/food research, and (iii) the greatest opportunities for the development of citizen science projects in agriculture and food science will be gained by using the existing infrastructure and tools of Extension programmes and through the engagement of urban communities. Further, we argue there is no better time to foster greater collaboration between these fields given the trend of shrinking Extension programmes, the increasing need to apply innovative solutions to address rising demands on agricultural systems, and the exponential growth of the field of citizen science.

Abstract
BACKGROUND Handwashing sink drains are increasingly implicated as a potential reservoir of antibiotic-resistant bacteria in hospital outbreaks; however, usage patterns that may promote this source remain unknown. AIM To understand behaviours in the intensive care unit (ICU) that may facilitate establishment and nosocomial transmission of multidrug-resistant Gram negatives from a sink-trap reservoir to a patient. METHODS Motion-sensitive cameras captured anonymized activity paired with periodic in-person observations during a quality investigation from four ICU sinks (two patient rooms and two patient bathrooms) in a university hospital. FINDINGS We analysed 4810 sink videos from 60 days in patient rooms (3625) and adjoining bathrooms (1185). There was a false-positive rate of 38% (1837 out of 4810) in which the camera triggered but no sink interaction occurred. Of the 2973 videos with analysed behaviours there were 5614 observed behaviours which were assessed as: 37.4% medical care, 29.2% additional behaviours, 17.0% hand hygiene, 7.2% patient nutrition, 5.0% environmental care, 4.2% non-medical care. Handwashing was only 4% (224 out of 5614) of total behaviours. Sub-analysis of 2748 of the later videos further categorized 56 activities where a variety of nutrients, which could promote microbial growth, were disposed of in the sink. CONCLUSION Several non-hand hygiene activities took place regularly in ICU handwashing sinks; these may provide a mechanism for nosocomial transmission and promotion of bacterial growth in the drain. Redesigning hospital workflow and sink usage may be necessary as it becomes apparent that sink drains may be a reservoir for transmission of multidrug-resistant bacteria.

Abstract
Anti-tumour necrosis factor (anti-TNF) therapies have been associated with neurological complications, including in rare cases demyelinating disease. It is currently unknown whether patients who have received more than one immunosuppressive agent or anti-TNF have a greater risk of demyelination. We report the case of a 37-year-old woman with psoriasis who presented with an acute episode of demyelination while on anti-TNF therapy. This case was complicated by the fact that progressive multifocal leukoencephalopathy was considered the likely diagnosis initially and was only definitively excluded by brain biopsy. This case demonstrates the difficulty establishing the correct diagnosis in patients with atypical presentations on immunomodulating therapies. We present this rare case of demyelination in a patient who received multiple immunosuppressive therapies to highlight this challenging clinical situation and discuss management with a literature review.

Abstract
This study investigated the purpose and effectiveness of giving outpatients an opportunity to engage in art activities while receiving dialysis treatment. A mixed method study was conducted. 21 semi-structured interviews were conducted with outpatients attending the dialysis unit and 13 surveys of clinicians were completed. The principle reasons to partake in the art activity programme included: to pass time, to relieve boredom, to be creative, to try something new, distraction from concerns, to stay positive and to achieve something new. Patients who did not participate in the programme pass their time primarily by watching TV or sleeping. All staff who partook in the survey were satisfied with the programme and wanted it to continue. Our findings indicate that the creative arts programme is viewed positively by staff and patients alike, and might be useful in other hospital departments. Further in depth qualitative research would be useful to interrogate the potential effect of engagement in art on positive mental health and quality of life for patients with chronic conditions.

Abstract
IR spectroscopy of gas-phase ions is proposed to resolve positional isomers of sulfated carbohydrates. Mass spectrometric fingerprints and gas-phase vibrational spectra in the near and mid-IR regions were obtained for sulfated monosaccharides, yielding unambiguous signatures of sulfated isomers. We report the first systematic exploration of the biologically relevant but notoriously challenging deprotonated state in the near IR region. Remarkably, anions displayed very atypical vibrational profiles, which challenge the well-established DFT (Density Functionnal Theory) modeling. The proposed approach was used to elucidate the sulfate patterns in glycosaminoglycans, a ubiquitous class of mammalian carbohydrates, which is regarded as a major challenge in carbohydrate structural analysis. Isomeric glycosaminoglycan disaccharides from heparin and chondroitin sources were resolved, highlighting the potential of infrared multiple photon dissociation spectroscopy as a novel structural tool for carbohydrates.

Abstract
OBJECTIVE The objective of this study was to investigate incidence and mortality from ischemic stroke in older adults with specific underlying chronic conditions, evaluating the influence of these conditions in developing stroke. MATERIALS & METHODS Population-based cohort study involving 27,204 individuals ≥60 years old in Southern Catalonia, Spain. All cases of hospitalization from ischemic stroke (confirmed by neuro-imaging) were collected from 01/12/2008 until 30/11/2011. Incidence rates and 30-day mortality were estimated according to age, sex, chronic illnesses, and underlying conditions. Multivariable Cox regression analysis was used to calculate Hazards Ratio (HR) and estimate the association between baseline conditions and risk of developing stroke. RESULTS Mean incidence rate reached 453 cases per 100,000 person-years. Maximum rates appeared among individuals with history of prior stroke (2926 per 100,000), atrial fibrillation (1815 per 100,000), coronary artery disease (1104 per 100,000), nursing-home residence (1014 per 100,000), and advanced age ≥80 years (1006 per 100,000). Thirty-day mortality was 13% overall, reaching 21% among patients over 80 years. Age [HR: 1.06; 95% confidence interval (CI): 1.04-1.07], history of prior stroke (HR: 5.08; 95% CI: 3.96-6.51), history of coronary artery disease (HR: 1.65; 95% CI: 1.21-2.25), atrial fibrillation (HR: 2.96; 95% CI: 2.30-3.81), diabetes mellitus (HR: 1.55; 95% CI: 1.23-1.95), and smoking (HR: 1.64; 95% CI: 1.15-2.34) emerged independently associated with an increased risk of ischemic stroke. CONCLUSION Incidence and mortality from ischemic stroke remains considerable. Apart from age and history of atherosclerosis (prior stroke or coronary artery disease), atrial fibrillation, diabetes, and smoking were the underlying conditions most strongly associated with an increased risk.

Abstract
We report on a patient who developed donor-derived cutaneous T-cell lymphoma (CTCL) 4 years after successful treatment of chronic myeloid leukaemia with an allogeneic bone marrow transplant. The patient developed an eczematous rash unresponsive to topical therapy and immunosuppression. When CTCL was diagnosed in the recipient, his sibling donor had been attending his local dermatology unit with a maculosquamous rash, which proved subsequently to be mycosis fungoides. An identical pattern of donor and recipient clonality assessment and T-cell receptor gene sequencing indicated that the CTCL was probably transmitted in the bone marrow harvest. This suggests that CTCL cells circulate in the marrow at an early subclinical stage in this disease. This is the second case of donor-derived CTCL reported to date.

Abstract
Folliculitis barbae is a common condition of both infective and non-infectious aetiology. It most frequently presents as a superficial folliculitis, with fine pustules appearing at the opening of hair follicles in the beard area, often associated with shaving; known as Bockhart impetigo and usually due to infection caused by Staphylococcus aureus. If untreated, the infection and inflammation can progress, leading to a more deeply seated infection known as sycosis barbae. Perifollicular nodules, termed furuncles, may appear and when these are multiple and coalesce, a deep-seated, communicating, pustulating plaque called a carbuncle develops, often with associated systemic upset. Such an appearance, which can prompt incision and drainage, should not, however, be assumed to be solely due to staphylococcal infection. Particularly in the context of a history of close animal contact or a lack of response to antibiotic treatment, a diagnosis of tinea barbae should be considered and investigated. Prompt treatment with antifungal agents and often systemic steroids is required once the diagnosis is made. This will help reduce an exacerbation of the pronounced destruction that results from the immune response to the fungal infection, known as a kerion, which would be compounded by surgical intervention. In this article, we review two such cases and review the investigation and management of the disease.

Abstract
BACKGROUND The objective of this study is to outline a capabilities approach to the social determinants of population health and to compare its explanatory power and implications for public policy-making with psychosocial approaches. METHODS A model linking the structures of economic and social relations to health outcomes is developed and logistic methods used to confirm its base validity for a representative sample of 16,488 citizens in 19 developed democracies drawn from the World Values Surveys of 1990 and 2005. Self-reported health is the dependent variable. Age, gender, education, employment status, self-mastery, income, autonomy at work, ties to family and friends, subjective social status, associational memberships and sense of national belonging are considered. RESULTS At baseline, risk ratios reflecting movement from the 25th to 75th percentile in the distribution of the variable indicate that increases in income reduce the likelihood of poor health (0.78; 0.73-0.82) as does higher autonomy at work (0.90; 0.85-0.94) but so does access to social resources reflected in ties to family and friends (0.89; 0.86-0.92), associational memberships (0.93; 0.89-0.98), subjective social status (0.77; 0.54-0.90) while the absence of feelings of national belonging increases the likelihood of poor health (1.14; 1.06-1.23). CONCLUSION The results suggest that population health is dependent on the distribution of social as well as economic resources along the dimensions predicted by a capabilities model. Governments should be attentive to the impact of policy on the distribution of social, as well as economic, resources.

Abstract
Human epidermis is continuously exposed to environmental mutagenic hazard and is the most frequent target of human cancer. How the epidermis coordinates proliferation with differentiation to maintain homeostasis, even in hyperproliferative conditions, is unclear. For instance, overactivation of the proto-oncogene MYC in keratinocytes stimulates differentiation. Here we explore the cell cycle regulation as proliferating human keratinocytes commit to terminal differentiation upon loss of anchorage or overactivation of MYC. The S-phase of the cell cycle is deregulated as mitotic regulators are inhibited in the onset of differentiation. Experimental inhibition of mitotic kinase cdk1 or kinases of the mitosis spindle checkpoint Aurora B or Polo-like Kinase, triggered keratinocyte terminal differentiation. Furthermore, hyperactivation of the cell cycle by overexpressing the DNA replication regulator Cyclin E induced mitosis failure and differentiation. Inhibition of Cyclin E by shRNAs attenuated the induction of differentiation by MYC. In addition, we present evidence that Cyclin E induces DNA damage and the p53 pathway. The results provide novel clues for the mechanisms committing proliferative keratinocytes to differentiate, with implications for tissue homeostasis maintenance, HPV amplification and tumorigenesis.

Abstract
This study examined the spatio-temporal reproductive patterns, population structure, maturity and growth of Acanthopagrus hybrid complexes, which comprise mainly black bream Acanthopagrus butcheri and the hybrids they form with yellowfin bream Acanthopagrus australis, in two Australian estuaries (Coila and Brou Lakes, NSW). There were no differences between pure A. butcheri and hybrids in terms of their population structure, growth and maturity, suggesting that these two breeds have similar life histories and may therefore be managed as single, naturally cohesive units. Sexual variation in size structure was only observed for the complex in Coila Lake. Although there was significant variation in age structure between estuaries, both complexes exhibited dominance of only a few year classes indicating episodic recruitment and high fishing mortality. Acanthopagrus eggs occurred in higher numbers within upstream creek habitats compared to lake habitats, thereby highlighting the need to protect these spawning habitats. Although maturity in the complexes was not influenced by gender or estuary, differences in growth were detected between the genders and estuaries.

Abstract
Skull base surgery is a new subspeciality, and, up to this point, most articles on this subject have focused on innovative operative-reconstructive approaches to tumors in this region. It is now important that we embark on a new era, the era of tumor biology, and concentrate on new ways of evaluating these neoplasms from a pathologic viewpoint. The hematoxylin-cosin section is no longer an end point, but just a beginning. This is the age of molecular biology. It is important that these tumors be evaluated, either prospectively or retrospectively, employing immunohistochemical staining, flow cytometry, oncogene expression, cytogenetics, or other techniques in order to identify important prognostic features. Data from these additional studies may then be used to develop new treatment strategies. Skull base societies should develop protocols for one or more of these tumors to ensure that they are indeed evaluated uniformly. In this article I emphasize the importance of accurate histologic classification or subclassification of these neoplasms and focus on contemporary parameters that may or may not impact on prognosis.

Abstract
Angiofibromas are histologically benign but locally aggressive tumors that often extend beyond the nasopharynx to involve contiguous structures. In addition, attempts to remove the tumors surgically are often frustrated by local recurrences. We studied 31 angiofibromas by flow cytometry to determine if tumor ploidy could be used to identify those tumors that might behave more aggressively. The patients, all males between 5 and 23 years of age, were divided into two groups. The 21 patients with tumors confined to the nasopharynx or paranasal sinuses were regarded as having local disease, the ten with tumors involving the infratemporal fossa, orbit, cheek, or intracranial structures were regarded as having extensive disease. Of the ten with extensive disease, six bad intracranial involvement. All patients were treated with surgery and only one received postoperative irradiation. Follow-up was available in 24, eight of which developed local recurrences (33%). All tumors, including recurrences and those with intracranial extension, were found to be diploid. We therefore conclude that tumor ploidy cannot be used to predict the clinical course of angiofibromas.

Abstract
UK medical school curricula incorporate training in end-of-life care as recommended by Tomorrow's Doctors. Previous research suggests that hospice staff have concerns about the burden on patients when participating in medical student teaching and may gatekeep access to patients. This qualitative study uses semistructured interviews to explore and compare the views of hospice patients and health care staff about patient involvement in medical student teaching. Fifteen patients and 14 staff members were recruited from a single UK hospice involved in teaching third year medical students. Hospice patients, who have been involved in teaching, are strongly positive about meeting medical students and staff carefully select patients based on a number of issues.

Abstract
BACKGROUND Most persons who are infected with human immunodeficiency virus type 1 (HIV-1) are also infected with herpes simplex virus type 2 (HSV-2), which is frequently reactivated and is associated with increased plasma and genital levels of HIV-1. Therapy to suppress HSV-2 reduces the frequency of reactivation of HSV-2 as well as HIV-1 levels, suggesting that suppression of HSV-2 may reduce the risk of transmission of HIV-1. METHODS We conducted a randomized, placebo-controlled trial of suppressive therapy for HSV-2 (acyclovir at a dose of 400 mg orally twice daily) in couples in which only one of the partners was seropositive for HIV-1 (CD4 count, > or = 250 cells per cubic millimeter) and that partner was also infected with HSV-2 and was not taking antiretroviral therapy at the time of enrollment. The primary end point was transmission of HIV-1 to the partner who was not initially infected with HIV-1; linkage of transmissions was assessed by means of genetic sequencing of viruses. RESULTS A total of 3408 couples were enrolled at 14 sites in Africa. Of the partners who were infected with HIV-1, 68% were women, and the baseline median CD4 count was 462 cells per cubic millimeter. Of 132 HIV-1 seroconversions that occurred after randomization (an incidence of 2.7 per 100 person-years), 84 were linked within couples by viral sequencing: 41 in the acyclovir group and 43 in the placebo group (hazard ratio with acyclovir, 0.92, 95% confidence interval [CI], 0.60 to 1.41; P=0.69). Suppression with acyclovir reduced the mean plasma concentration of HIV-1 by 0.25 log(10) copies per milliliter (95% CI, 0.22 to 0.29; P<0.001) and the occurrence of HSV-2-positive genital ulcers by 73% (risk ratio, 0.27; 95% CI, 0.20 to 0.36; P<0.001). A total of 92% of the partners infected with HIV-1 and 84% of the partners not infected with HIV-1 remained in the study for 24 months. The level of adherence to the dispensed study drug was 96%. No serious adverse events related to acyclovir were observed. CONCLUSIONS Daily acyclovir therapy did not reduce the risk of transmission of HIV-1, despite a reduction in plasma HIV-1 RNA of 0.25 log(10) copies per milliliter and a 73% reduction in the occurrence of genital ulcers due to HSV-2.

Abstract
BACKGROUND There is a need for new treatments for scalp psoriasis, as many topical treatments are cosmetically unacceptable and difficult to apply, resulting in poor compliance. OBJECTIVES To compare the efficacy and safety of a new, once-daily, two-compound scalp formulation (Xamiol; LEO Pharma A/S, Ballerup, Denmark) containing calcipotriol 50 microg g(-1) plus betamethasone 0.5 mg g(-1) (as dipropionate), with the active ingredients as single compounds in the same vehicle. METHODS This 8-week, multicentre, double-blind, parallel-group study, randomized adult patients with scalp psoriasis involving > 10% of the scalp to the two-compound scalp formulation (n = 568), betamethasone dipropionate 0.5 mg g(-1) (n = 563), or calcipotriol 50 microg g(-1) (n = 286). The primary efficacy measure was the proportion of patients with 'absence of disease' or 'very mild disease' according to investigators' assessments at week 8. RESULTS The proportion of patients with 'absence of disease' or 'very mild disease' at week 8 was significantly higher in the two-compound group (68.4%) than the betamethasone dipropionate (61.0%, P = 0.0079) or calcipotriol (43.4%, P < 0.0001) groups. The proportion of patients rating their scalp psoriasis as 'clear' or 'almost clear' was significantly higher for the two-compound scalp formulation (69.6%) than for betamethasone dipropionate (59.9%, P = 0.0006) or calcipotriol (44.7%, P < 0.0001). The incidence of lesional/perilesional adverse events was lower in the two-compound and betamethasone dipropionate groups than the calcipotriol group. CONCLUSIONS The two-compound scalp formulation was well tolerated and more effective in the treatment of scalp psoriasis than either of its individual components in the same vehicle.

Abstract
We present a case of pyoderma gangrenosum (PG) mimicking a lung carcinoma. A 52-year-old woman presented with an unremitting cough. Computed tomography revealed a cavitating lung lesion. Bronchoscopy and biopsy were interpreted as squamous cell carcinoma. Following a staging mediastinoscopy, a sleeve lobectomy and chest-wall resection was performed. The pulmonary histopathological features suggested Wegener's granulomatosis; no malignancy was found. Three months postoperatively, wound breakdown led to dermatological review. A clinical diagnosis of cutaneous PG was made on the basis of the classic appearance of the surgical wounds and an ulcer on the upper back that had been present before surgery. The patient has been consistently negative for cytoplasmic-staining antineutrophil cytoplasmic antibodies, which supports the diagnosis of PG with cutaneous and pulmonary involvement. Lung manifestations of PG are rare. PG is amenable to systemic therapy. Pulmonary PG is a rare but important differential diagnosis that is not familiar to many physicians and surgeons in this type of presentation.

Abstract
The majority of patients with dermatitis herpetiformis (DH) have small intestinal enteropathy that may result in bone loss. The objective of this study was to evaluate bone mineral density (BMD) in DH and to examine whether dietary treatment or degree of the small intestinal lesion correlate with BMD. Twenty-five patients with DH (18 men) were investigated. Detailed dietary assessment and duodenal biopsies were performed on all patients before entry into the study. BMD at lumbar spine and femur was determined by DXA scan. Bone biomarkers, vitamin D, and parathyroid status were assessed. Twenty patients had enteropathy. None of the patients had hypovitaminosis D or secondary hyperparathyroidism. Resorption and formation markers were within normal limits. BMD Z-scores were not significantly different from expected (-0.38; CI, -0.84 to 0.07) and femur (0.46; CI, -0.06 to 0.97). There was no relationship between BMD Z-scores and the severity of the degree of enteropathy. We conclude that enteropathy of differing severity is present in 80% of patients with DH, but this is not associated with bone disease.

Abstract
BACKGROUND The calcipotriol/betamethasone dipropionate two-compound product is safe and effective in the short-term treatment of psoriasis. OBJECTIVE The primary objective was to investigate the safety of two treatment regimens involving use of the two-compound product over 52 weeks. The efficacy results are presented here. METHODS Six hundred and thirty-four patients were randomised double-blind to treatment (once daily, when required) with either: 52 weeks of two-compound product (two-compound group), 52 weeks of alternating 4-week periods of two-compound product and calcipotriol (alternating group), or 4 weeks of two-compound product followed by 48 weeks of calcipotriol (calcipotriol group). RESULTS There was a trend towards a difference between treatments from the overall treatment effect for the percentage of satisfactory responses for each patient during the study (p = 0.071). This appeared to be due to the comparison of the two-compound and calcipotriol groups (p = 0.025). CONCLUSION There was a trend towards the efficacy of the two-compound product used for up to 52 weeks being better than that of 4 weeks of the two-compound product followed by 48 weeks of calcipotriol.

Abstract
The mortality and morbidity associated with basal cell carcinoma (BCC) is low. However, BCCs represent a significant burden to the health service due to their high and increasing incidence. This audit was designed to examine the management of BCCs by a dermatology department and to highlight deficiencies in the service offered to patients. The mean intervals between the first dermatology clinic visit and definitive treatment by the dermatology and the plastic surgery departments were 62 and 129 days respectively. Factors contributing to the delay included the frequent use of diagnostic incisional biopsies and the high referral rate from dermatology to the department of plastic and reconstructive surgery. In 90% of cases the dermatologist made an accurate clinical diagnosis. Despite this, diagnostic biopsies were performed in 72% of cases, often necessitating additional hospital visits. Forty three percent of cases were treated definitively by dermatology, whereas over 50% were referred to the department of plastic surgery. A number of changes are planned or are in process as a consequence of the audit.

Abstract
BACKGROUND The calcipotriol/betamethasone dipropionate two-compound product Dovobet/Daivobet/Taclonex(LEO Pharma A/S, Ballerup, Denmark) has been shown to be safe and effective in the treatment of psoriasis for up to 8 weeks. As psoriasis is a chronic disease, long-term treatment may be required, so there is a need to investigate the safety of its use over a longer period of time. OBJECTIVES To investigate the safety of two treatment regimens involving use of the two-compound product over 52 weeks in the treatment of patients with psoriasis. METHODS Patients (n = 634) were randomized double-blind to treatment with: (i) 52 weeks of the two-compound product (two-compound group); (ii) 52 weeks of alternating 4-week periods of the two-compound product and calcipotriol (alternating group); or (iii) 4 weeks of the two-compound product followed by 48 weeks of calcipotriol (calcipotriol group). Treatments in all groups were used once daily when required. RESULTS Adverse drug reactions (ADRs) occurred in 45 (21.7%) patients in the two-compound group, 63 (29.6%) in the alternating group and 78 (37.9%) in the calcipotriol group. The odds ratio for an ADR in the two-compound group relative to the calcipotriol group was 0.46 (95% confidence interval 0.30-0.70; P < 0.001). ADRs of concern associated with long-term topical corticosteroid use occurred in 10 (4.8%) patients in the two-compound group, six (2.8%) in the alternating group and six (2.9%) in the calcipotriol group; those with the highest incidence were skin atrophy, occurring in four (1.9%), one (0.5%) and two (1.0%) patients, respectively, and folliculitis, in three (1.4%), one (0.5%) and no patients, respectively. CONCLUSIONS Treatment with the two-compound product for up to 52 weeks appears to be safe and well tolerated whether used on its own or alternating every 4 weeks with calcipotriol treatment.

Abstract
Necrotising fascitis is a fulminant infective process which can result in significant morbidity and can indeed be life threatening. It needs to be recognised early and managed aggressively with extensive surgical debridement followed by appropriate antibiotics. On the other hand, Pyoderma gangrenosum is a disease process that needs to be managed non-surgically. We present one such case, the diagnosis of which had treaded along the thin line between the two.

Abstract
Bacterial leaf scorch caused by Xylella fastidiosa has been reported on oleander in California (3) and Florida (4). In June 2002, leaf scorch symptoms including chlorotic mottling of leaves, necrosis on leaf tips or whole leaves, defoliation, and shortened internodes were observed in oleander plants at various locations in Texas, including Galveston, Harlingen, Austin, San Antonio, and El Campo. The symptomatic varieties Calypso, Commandant Barthelemy, Lane Taylor Sealy, Little Red, Mrs. George Roeding, Mrs. Runge, Scarlet Beauty, and Petite Salmon, as well as symptomless varieties, Turner's Shari D and Sugarland from Moody Gardens in Galveston, Texas were sampled. All samples were tested for the presence of X. fastidiosa using enzyme-linked immunosorbent assay (ELISA) and bacterial isolation according to the methods of Huang and Sherald (2). All symptomatic varieties reacted positively in ELISA, and colonies characteristic of X. fastidiosa were isolated from all eight symptomatic varieties 10 to 15 days after incubation at 28°C. The colonies were confirmed to be X. fastidiosa using polymerase chain reaction (PCR) (2). ELISA tests and bacterial isolations from the symptomless Shari D and Sugarland varieties were negative. Membrane entrapment immunofluorescence (MEIF) (1) using the antibody CREC 26 to X. fastidiosa was also done on three of the symptomatic varieties and one asymptomatic variety obtained from Moody Gardens, and fluorescing bacteria were found only in the three symptomatic varieties. Symptomatic samples of Petite Salmon, one pink variety and one red variety obtained from a residential area west of Galveston, and a red oleander in Harlingen, TX, also tested positive with MEIF. Other ELISA-positive samples were obtained from symptomatic oleanders from Austin, San Antonio, and El Campo, TX. The X. fastidiosa bacteria isolated from the variety Lane Taylor Sealy were used to inoculate three red oleander plants by making an 8-cm-long vertical cut into the stem and then in 15 locations injecting approximately 15 μl of a X. fastidiosa suspension (108-9 cells per ml). The cut area was wrapped with Parafilm after inoculation, and the plants were kept at 29°C in a greenhouse. Three healthy red oleanders were inoculated with periwinkle wilt liquid medium for controls. Approximately 3 months after inoculation, chlorotic mottling along the edges of leaves was observed in the oleanders inoculated with X. fastidiosa, and the bacterium was reisolated from symptomatic leaves as described above. No symptoms were observed on the control plants, and bacterial isolation from the control plants was also negative. To our knowledge, this is the first report to show the causal role of X. fastidiosa in oleander leaf scorch and the presence of the disease in different locations in Texas, extending the geographic range of this important bacterial disease.

Abstract
BACKGROUND Acupuncture is widely used by the American public, but little is known about its availability and use in academic medical settings. We performed a pilot study to compare acupuncture services provided by hospitals affiliated with a major academic teaching institution, and a parallel survey of services provided through an acupuncture school in one city in New England. METHODS Between December 2000 and July 2001, a telephone survey was conducted of the 13 hospitals affiliated with Harvard Medical School, and the clinics affiliated with the New England School of Acupuncture. RESULTS Acupuncture was available in 8 of the 13 hospitals. Acupuncture was provided in ambulatory clinics in all eight hospitals, but was available to inpatients in only one hospital. Six hospitals delivered acupuncture through an outpatient pain treatment service, one through a women's health center, one through an HIV clinic, and one hospital delivered acupuncture through two services; a program in the anesthesia department and a multi-disciplinary holistic program in a primary care department. In contrast, the acupuncture school clinics provided services through an on-site clinic at the school, through acupuncture departments at two community-based hospitals, and through a network of 12 satellite acupuncture-dedicated clinics operating throughout the state. CONCLUSION Acupuncture is available on a limited basis in a majority of the teaching hospitals in this city. At the acupuncture school clinics, there are few barriers to care. Future health care studies will need to examine the role of acupuncture in diverse geographic settings and to examine its impact on quality of care, teaching and its role in research in academic centers.
