Rechallenge and retreatment with topical imiquimod 5% in transplant recipients: A multicenter experience on actinic keratoses and basal cell carcinomas

AbstractBackgroundSolid organ transplant recipients (SOTRs) have an increased risk of developing non melanoma skin cancers (NMSCs). The use of Imiquimod, a toll‐like‐receptor agonist, is still debated in SOTRs.ObjectivesThe aim of this study was to evaluate efficacy and safety of topical Imiquimod in two Dermatology Centres for skin cancers in SOTRs.MethodsAll SOTRs with age > 18 and a dermoscopic diagnosis of superficial basal cell carcinoma (BCC) and/or actinic keratose (AK), annually followed up between January 2022 and December 2022 were screened.Results80 NMSCs (41 BCC and 39 AK) in 66 SOTRs were identified and treated.57 (86.4%) were male. The mean age was 66.2 years (30−85). 60 patients (90.1%) had transplanted kidney, 1 (1.5%) lung, 3 (4.5%) liver, and 1 (1.5%) heart.The average time since first transplant was 17 years (3−40 years). Tacrolimus, steroids, and mycophenolate mofetil were the most frequently used immunosuppressants (71%; 67.7%; 53.2% of cases, respectively).Responses to the first course of treatment were CR in 64.3% of cases (53.6% in AK; 67.7% in BCC); PR in 28.6% of cases (42.9% in AK; 12.9% in BCC); NR in 12.5% of cases (3.6% in AK; 19.4% in BCC). Fourteen patients received a second course of imiquimod for a persistent lesion (1 AK, 4 BCC) or a new lesion (4 AK, 5 BCC).Responses to the second course of treatment were observed in 4 (80%) and 7 (78%) cases in the persistent and new lesion, respectively (p = 0.34).No systemic adverse events were noted. The main side effects were mild: erythema, scales, and crusts, itching, or pain.ConclusionsTopical imiquimod represents a viable and safe option in this category of patients.The response to imiquimod in subjects who have had more than one cycle is not related to the response to previous treatments but rather to the intrinsic characteristics of the lesion.

Skin manifestations and human immunodeficiency virus infection in the Tigray region, Ethiopia: Implications for clinical management and epidemiologic surveillance

AbstractBackgroundPatients with human immunodeficiency virus (HIV) infection may present a large variety of skin manifestations, often associated with significant morbidity. In turn, dermatological diseases may represent an early sign of HIV infection, particularly in resource‐limited settings.ObjectivesThis study aimed to assess the spectrum of dermatological diseases and their potential value as clinical proxies for the early detection and management of HIV in a rural region of Ethiopia.MethodsThe study was performed on a population of 67,161 patients with skin diseases attending the Italian Dermatological Center in Mekele, Tigray region, Ethiopia. HIV infection was diagnosed in 1892 individuals (1065 female), all naïve to antiretroviral therapy.ResultsInfectious skin diseases were present in 57.2% of the total HIV population. Among the infectious skin manifestations, dermatophytosis (20.5%), impetigo (5.9%), candidiasis (4.7%) and molluscum contagiosum (4.7%) were significantly more represented in patients with HIV infection (p < 0.001). Regarding the noninfectious manifestations, pruritus and atrophy of the papillae on the tongue were significantly associated with HIV (p < 0.001). Notably, females had a significantly higher incidence of dermatophytosis and seborrheic dermatitis as compared to their male counterparts (p < 0.001), whereas scabies, psoriasis and leishmaniasis were significantly more frequent in males (p < 0.001).ConclusionsSkin manifestations are common in HIV patients, often reflecting compromised immune status. In addition, Dermatophytosis and pruritus were the most frequently reported manifestations of HIV, thus representing useful clinical proxies to raise the suspicion of an underlying HIV infection. Besides, gender differences in skin manifestations should also be considered in the clinical evaluation.

An Eastern County from an European Eastern Country-The Characteristics of Cutaneous Microbiome in Psoriasis Patients-Preliminary Results.

The cutaneous microbiome represents a topic of high interest nowadays. Multiple studies have suggested the importance of the skin microbiome in different dermatological pathologies, highlighting the possible implications of cutaneous microorganisms in either the pathogenesis or prognosis of skin maladies. Psoriasis represents a common inflammatory skin disease, with a high prevalence in the worldwide population. The role of the cutaneous microbiome in psoriasis could explain a number of pathogenic theories and treatment objectives of this incurable skin disease. Our interest in the characteristics of the cutaneous microbiome, especially in psoriatic patients who attended a tertiary dermatological centre in Galati, Romania, is reflected in our current study, of which the preliminary results are discussed in this article. Using three types of skin sampling techniques (swabs, adhesive tape, and punch biopsies), we tried to characterise the microorganisms harboured in the skin of psoriatic patients and healthy individuals. This study was performed using culture-based probes, which were analysed using MALDI-TOF mass spectrometer equipment. Our preliminary results suggested that the greatest diversity was observed in the perilesional areas of psoriatic patients. The lowest cutaneous diversity was obtained from sampling psoriatic plaques. These results are similar to other studies of the cutaneous microbiome in psoriasis. The most frequent microorganisms found in all groups studied were of the Staphylococcus species: Staphylococcus epidermidis, Staphylococcus hominis, and Staphylococcus aureus. Analysing the living environment of each individual from this study, our preliminary results suggested different results from other studies, as higher diversity and heterogenicity was observed in urban environments than in rural living areas. Regarding the differences between sexes, our preliminary results showed higher quantitative and qualitative changes in the skin microbiome of male participants than female participants, opposite to the results found in other studies of the cutaneous microbiome in psoriasis. Given these preliminary results, we can conclude that we have found important differences by studying the cutaneous microbiome of psoriatic patients and healthy control individuals from a population that, to our knowledge, has not been yet studied from this point of view. Our results showed important characteristics of the skin microbiome in an Eastern European population, where cultural and environmental living habits could influence the cutaneous microbiome.

Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) after administration of corticosteroids: Case series and review of literature.

Cutaneous manifestations of drug-induced type IV reactions vary widely, with symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) being a less common presentation. Corticosteroids (CS), primarily known for their anti-inflammatory effects, rarely induce hypersensitivity reactions. The aim of this case series is to report four cases of SDRIFE following systemic prednisolone therapy and to review existing CS classification proposals to better understand cross-reactivity of CS. Patients recruited at a German dermatology centre underwent allergologic evaluation including prick and patch testing with various CS. Positive cases underwent oral challenge testing with alternative agents. The classification systems of Coopman et al. and Baeck et al. were taken into account. Despite a paucity of literature, CS-induced type IV reactions do occur, including SDRIFE. Classification systems based on chemical structure provide insight into cross-reactivity patterns. Provocation tests with alternative CS highlight the complexity of managing CS hypersensitivity. SDRIFE may develop following systemic prednisolone therapy. Classification systems are helpful in understanding cross-reactivity and help in the selection of alternative preparations but are not always reliable. Individualised assessment is crucial for managing CS hypersensitivity, with consideration of alternative agents and emergency use of CS when necessary.

Antibiotic adherence in dermatologic surgery: a Multicenter prospective cohort study.

Understanding patient non-adherence to prescribed antibiotics can inform clinical practices, patient counseling, and antibiotic efficacy study design in dermatology. The primary objective was to determine the rate of and reasons for antibiotic non-adherence in the dermatologic surgery setting. The secondary objective was to test the applicability of previously studied survey questions for antibiotic non-adherence screening in the dermatologic surgery setting. Five academic outpatient dermatologic surgery centers across the United States conducted one multicenter prospective cohort study. Dermatologic surgery patients ≥ 18 years of age who were prescribed an antibiotic were included as part of this study. 15.2% (42/276) of patients did not adhere to their antibiotic regimen after dermatologic surgery. Most common reasons for incomplete antibiotic courses included forgotten antibiotics (42.9%,18/42) and side effects (28.6%, 12/42). Previously evaluated questions to identify and predict non-adherence had modest performance in the dermatologic surgery setting (Area under the curve of 0.669 [95% CI (0.583-0.754)]). Antibiotic non-adherence after skin surgery is prevalent and commonly due to reasons that physicians can address with patients.

A Randomized Controlled, Single-Observer Blinded Study on the Safety and Efficacy of a Combination of 678nm Helmet-Type Low-level Laser Therapy and Topical Minoxidil 5% Versus Topical Minoxidil 5% Alone in the Treatment of Male Androgenetic Alopecia

Male pattern androgenetic alopecia is a chronic, progressive condition with significant social and psychological impact. Few preliminary researches have been done on the role of low-level laser therapy as a treatment modality for male pattern hair loss. This is a randomized, controlled, single-observer blinded clinical trial conducted from November 2019 to October 2021 at the East Avenue Medical Center Dermatology Out-Patient Department on the use of low-level laser therapy and topical minoxidil for the treatment of androgenetic alopecia. Twenty-four male adults with Norwood Hamilton Hair Loss Scale of IIa to V were randomly assigned into 2 groups: a control group (monotherapy with topical minoxidil 5%) and a treatment group (678 nm helmet-type low-level laser therapy and topical minoxidil 5%). A statistically significant higher increase in hair density was observed in the treatment group (14.58 and 15.08 for the right and left sides, respectively) compared to the control (5.83 on the right and 5.50 on the left, respectively, p=.000 <.05). In addition, the investigator’s global photographic assessment and patient satisfaction were also significantly higher. Both treatments were well tolerated. The results of this study show that 678 nm helmet-type low-level laser therapy is an effective adjunctive treatment modality to topical minoxidil 5% solution for the treatment of male androgenetic alopecia.

Clinical features of drug reaction with eosinophilia and systemic symptoms: A retrospective study in a reference centre of dermatology in Madagascar

AbstractBackgroundDrug reaction with eosinophilia and systemic symptoms (DRESS) is drug‐induced hypersensitivity reaction that can have fatal complications. Three sets of diagnostic criteria have been proposed, however, consensus is lacking.ObjectivesThis study aimed to describe the causative agents, severity, and the clinical course of patients with DRESS in Antananarivo, Madagascar.MethodsA cross‐sectional study was conducted in patients seen for DRESS, in the department of dermatology at the University Hospital Antananarivo, Madagascar from 2014 to 2022. European Registry of Severe Cutaneous Adverse Reactions (RegiSCAR) criteria was used for the diagnosis. Demographic data, latency periods, clinical and laboratory findings, culprit drugs, and outcomes were assessed.ResultsA total of 24 patients were included. Fifteen patients were female. The three most common culprit drugs were carbamazepine (17 patients), phenobarbital (2 patients), and ampicilline (2 patients). Median onset time (interquartile range) was 20 days (range: 7–62 days). Skin rash was present in all patients, and fever in 18 patients. A total of 12 patients showed two or more internal organs involved. Liver and kidney injuries were the most common visceral manifestation. All patients had eosinophilia. Fifteen patients received systemic corticosteroids. Two mortality cases were reported due to DRESS‐related fulminant liver failure and to nosocomial respiratory infection. Mortality was associated with higher eosinophilia (p = 0.03), higher creatininemia (p = 0.04), and shorter time of latency (p = 0.04).ConclusionsOur study show that DRESS is associated with severe morbidity. Early detection and withdrawal of the culprit dru gis crucial to save life and reduce morbidity.

Impact of Biologic Therapy on Key Cardiovascular Risk Parameters in a Psoriatic Cohort-a Retrospective Review.

Psoriasis is a risk factor for cardiovascular disease. Biologic agents have revolutionised psoriatic skin control. This study aims to assess the change in cardiovascular risk factors in a cohort of patients treated with 1 year of continuous biologic treatment. A retrospective medical record review was conducted of consecutive patients receiving biologic therapy for chronic plaque psoriasis in a single dermatology centre at a major tertiary hospital in Australia. The effect of biologic therapy on psoriasis was assessed using a psoriasis area severity index (PASI). Cardiovascular risk factors included systolic blood pressure (SBP), diastolic BP (DBP), heart rate (HR) and body mass index (BMI). Measurements at baseline and 1-year follow-up were compared using paired t-tests. A total of 106 patients were reviewed with a median age of 44 years, and 63% of the patients were male. At baseline, mean BMI was 30 (SD 7), mean SBP was 129 (SD 17), mean DBP was 81 (SD 9) and mean HR was 82 (SD 14). Over 12months, the PASI was reduced from 17.4 (SD 8.5) to 1.4 (SD 1.7, p < 0.001) indicating skin improvement. There was no significant difference from baseline in SBP (difference 2.3mmHg, 95% CI - 1.4-5.9), DBP (0.6mmHg, 95% CI - 1.2-2.5), BMI (difference - 0.1kg/m2, 95% CI - 0.9-0.7) or HR (difference 1.3, 95% CI - 3.9-6.4). In patients with psoriasis, markers of cardiovascular disease risk did not improve after 1year of biologic therapy despite significant improvements in psoriasis skin severity.

Stigmatization and Mental Health Impact of Chronic Pediatric Skin Disorders

Chronic skin disorders in children frequently are visible and can cause stigmatization. However, the extent of stigmatization from chronic skin disease and association with mental health needs further study. To examine the extent of stigma, dependence on disease visibility and severity, and association with mental health and quality of life (QOL) in chronic pediatric skin disease. A cross-sectional, single-visit study was conducted at 32 pediatric dermatology centers in the US and Canada from November 14, 2018, to November 17, 2021. Participants included patients aged 8 to 17 years with chronic skin disease and 1 parent. Using the Patient-Reported Outcomes Measurement Instrumentation System (PROMIS) Stigma-Skin, the extent of stigma with child-, caregiver-, and physician-assessed disease visibility (primary outcome) and severity was compared, as well as reduced QOL (assessed by Skindex-Teen), depression, anxiety, and poor peer relationships (PROMIS child and proxy tools) (secondary outcomes). The study included 1671 children (57.9% female; mean [SD] age, 13.7 [2.7] years). A total of 56.4% participants had self-reported high disease visibility and 50.5% had moderate disease severity. Stigma scores significantly differed by level of physician-assessed and child/proxy-assessed disease visibility and severity. Among children with chronic skin disorders, predominantly acne, atopic dermatitis, alopecia areata, and vitiligo, only 27.0% had T scores less than 40 (minimal or no stigma) and 43.8% had at least moderate stigma (T score ≥45) compared with children with a range of chronic diseases. Stigma scores correlated strongly with reduced QOL (Spearman ρ = 0.73), depression (ρ = 0.61), anxiety (ρ = 0.54), and poor peer relationships (ρ = -0.49). Overall, 29.4% of parents were aware of bullying of their child, which was strongly associated with stigma (Cohen d = -0.79, with children who were not bullied experiencing lower levels of stigma). Girls reported more stigma than boys (Cohen d = 0.26). Children with hyperhidrosis and hidradenitis suppurativa were most likely to have increased depression and anxiety. The findings of this study suggest that physician assessment of disease severity and visibility is insufficient to evaluate the disease impact in the patient/caregiver. Identifying stigmatization, including bullying, and tracking improvement through medical and psychosocial interventions may be a key role for practitioners.

Patient-Reported Outcome Measures in Atopic Dermatitis and Chronic Urticaria Are Underused in Clinical Practice

BackgroundPatient-reported outcome measures (PROMs) are validated and standardized tools that complement physician evaluations and guide treatment decisions. PROMs are crucial for monitoring atopic dermatitis (AD) and chronic urticaria (CU) in clinical practice, but there are unmet needs and knowledge gaps regarding their use in clinical practice. ObjectiveWe investigated the global real-world use of AD and CU PROMs in allergology and dermatology clinics as well as their associated local and regional networks. MethodsAcross 72 specialized allergy and dermatology centers and their local and regional networks, 2,534 physicians in 73 countries completed a 53-item questionnaire on the use of PROMs for AD and CU. ResultsOf 2,534 physicians, 1,308 were aware of PROMs. Of these, 14% and 15% used PROMs for AD and CU, respectively. Half of physicians who use PROMs do so only “rarely” or "sometimes". AD and CU PROM usage is associated with being female, younger, and a dermatologist. POSCORAD and UAS were the most utilized PROMs for AD and CU, respectively. Monitoring disease control and activity are the main drivers of the use of PROMs. Time constraints were the primary obstacle to using PROMs, followed by the impression that patients dislike PROMs. AD and CU PROM users would like training in selecting the proper PROM. ConclusionEven though PROMs offer several benefits, their use in routine practice is suboptimal, and physicians perceive barriers to their use. It is essential to attain higher levels of PROM implementation in accordance with national and international standards.

Development and validation of the Dermatology Social Comparison (DSC) Scale.

Social comparison, the process of evaluating one's characteristics in relation to others, influences individuals' self-perception and behavior. However, instruments are scarce for assessing social comparison in the medical setting. Our aim was to develop and validate a new scale for assessing social comparison. Seven statements were developed, encompassing the perceived normality of having rashes, the tendency to compare their situation with others, and the emotional response when seeing someone better or worse off than themselves. The instrument was piloted in 15 patients for readability and face validity, then prospectively validated using modern psychometric methods in 1,053 adult patients with eczema or psoriasis from three tertiary dermatological centers in Singapore. Of 1,053 adult patients, 802 (76.2%) had eczema, and 251 (23.8%) had psoriasis. Exploratory factor analysis (using a 70% sample split) showed a single factor model comprising three questions (Eigenvalue: 1.4). Confirmatory factor analysis with the remaining 30% of the sample confirmed an excellent model fit. Cronbach's alpha was 0.7, and inter-item correlations ranged from 0.42 to 0.46. In the Rasch analysis, item fit statistics and item characteristic curves showed appropriate discrimination between response options, although reliability was suboptimal with a person separation reliability of 0.63. Comprising 3 questions, the newly derived social comparison scale showed acceptable psychometrics as a measure of social comparison for clinical and research purposes in dermatology. Its brief nature likely results from its brevity and applicability to conditions beyond eczema and psoriasis, which warrants further investigation.

The Psychiatric Morbidity and Self-Esteem among Patients Suffering from Acne Vulgaris Attending Center of Dermatology and Venerology at Baghdad Teaching Hospital

Evaluation of Psychological Disorders in patients with Oral Lichen Planus; a Case Control Study.

Background and objective; Interest in the idea that immunological pathways may be involved in the etiology of subset of psychotic disorders has grown over the past few decades. The goal of this study was to investigate the psychiatric issues in individuals with oral lichen planus. Method; This is a case control study which has been done at Oral &amp; Maxillofacial medicine department in Khanzad Teaching Center and Erbil Dermatology Center between January 1st and August 1st, 2022. The Depression Anxiety Stress Scale -21 questionnaires were used to assess the psychological condition of patients with oral lichen planus. The sample consists of 100 participants, 50 of whom have oral lichen planus and 50 of healthy controls. Results: There were considerable differences between the two groups, according to the oral lichen planus the values for stress (50%), anxiety (22%), and depression (34%), whereas the values in the control group were [stress (20%), anxiety (0.0%), and depression (20%)]. Among the cases, (90.0%) had only oral lesions and (76.0%) of which had symptoms. Anxiety, and stress had statistical significance relation (0.002, 0.001) respectively in patients with symptomatic lesions (erosive and atrophic type) that produce pain and discomfort. Conclusion: The autoimmune diseases including the oral lichen planus has correlation with psychological factors, this research has shown the unfavorable impact of these oral lesions on the patient's psyche.

Lymphatic expression of the proliferation marker Ki67 is linked to sentinel node positivity, recurrence and mortality in primary cutaneous melanoma.

Lymphangiogenesis is a precursor to lymphovascular invasion, and may therefore signal a higher risk of metastasis and mortality in primary cutaneous melanoma. This retrospective longitudinal study aimed to evaluate whether emergent lymphangiogenesis, as measured through co-expression of endothelial proteins with the proliferation marker Ki67, was associated with poorer prognosis in a cohort of patients with single primary cutaneous melanoma. We screened all patients with a single locally invasive primary cutaneous melanoma who received sentinel lymph node biopsy at a tertiary dermatology centre in Brisbane, Australia between 1994 and 2007. Primary melanoma sections were stained via Opal multiplex immunofluorescence, and categorized according to the presence of Ki67 within either CD31+ or D2-40+ endothelial cells. Multivariate Cox regression modelling was used to evaluate associations between endothelial Ki67 positivity and clinical outcomes, with adjustment for age, sex, Breslow depth, ulceration, and anatomical location. Overall, 264 patients were available for analysis, with a median follow-up duration of 7.1 years. The presence of D2-40+ /Ki67+ co-expression was associated with greater melanoma-specific mortality (adjusted hazard ratio [HR]: 2.03; 95% confidence interval [CI]: 1.33-3.10; p = 0.001) and recurrence (adjusted HR: 1.70; 95% CI: 1.33-3.10; p = 0.001) relative to absence. CD31+ /Ki67+ co-expression was not prognostic in this cohort. Lymphatic proliferation, as measured through D2-40+ /Ki67+ co-expression, predicted greater melanoma-specific mortality and recurrence in this cohort of primary cutaneous melanoma.

Evaluation of a training course for general practitioners within the melanoma multimedia education programme of the Italian Melanoma Intergroup: a study protocol.

The text discusses the role of general practitioners (GPs) in the prevention and early diagnosis of melanoma, a type of skin cancer. It highlights the need for GPs to be able to recognize suspicious skin lesions and refer patients to specialist dermatology centers. However, many GPs lack comprehensive training in diagnosing melanoma. The text mentions that various training courses have been conducted for GPs, but their impact on clinical practice has been limited. The MelaMEd Programme is an e-learning course developed by the Italian Melanoma Intergroup (IMI). The programme aims to provide GPs with comprehensive knowledge of melanoma prevention, diagnosis, and treatment. It includes an e-learning section, and a dedicated platform called MelaMEd platform, which offers a multimedia atlas of melanoma. The objective of the study is to evaluate the impact of the MelaMEd programme on GPs' diagnostic accuracy, knowledge of melanoma, and management of suspicious lesions. The methodology involves administering pre-training and post-training questionnaires to participants, assessing their diagnostic skills and evaluating the training course's effectiveness. The study aims to demonstrate the effectiveness of the MelaMEd programme in improving GPs' ability to recognize and manage melanoma. It also seeks to identify areas for improvement and recommend interventions to enhance diagnostic accuracy. The results will be analyzed statistically using descriptive, univariate, and multivariate analysed methods.

Cost Assessment of Corticosteroid Therapy for Corticosteroid-sensitive Dermatoses in a Resource-limited Country

Introduction: Corticosteroid therapy is widely used in dermatology for treating various conditions. In France, the cost of corticosteroid treatment varies, and in Mali, a significant prevalence of corticosteroid-treated diseases has been reported. Given the prolonged treatment duration often required, understanding the cost implications in resource-limited settings is crucial. Patients and methods: This descriptive cross-sectional study took place at the dermatology department of the University Hospital Center of Dermatology in Bamako. Data were prospectively collected from patients undergoing corticosteroid therapy over one year. Variables included sociodemographic data, clinical information, and medication costs. Results: During the study period, 24 cases of dermatoses treated with corticosteroids were identified among 125 hospitalized patients, representing a prevalence of 19.2%. Most patients were women (58.3%), with an average age of 37.5 years. Lichen planus (54.2%) and pemphigus (37.5%) were the most common pathologies. Many patients had extensive lesions before treatment, but the majority responded well to corticosteroids. Discussion: Despite study limitations, such as its descriptive nature, it provided valuable insights into the economic evaluation of long-term corticosteroid therapy. The predominance of women, the age distribution, and the prevalence of specific dermatoses were highlighted. The study also revealed the substantial financial burden of corticosteroid treatment, primarily driven by direct costs. Conclusion: The study underscores the financial challenges associated with long-term corticosteroid therapy in dermatology in Mali. The high costs adversely affect patients and their families, especially considering the socioeconomic status of many patients. Moreover, the findings emphasize the importance of comprehensive care strategies and the need for accessible healthcare solutions to address these challenges effectively.

Sun protection knowledge, attitudes and practices: A Lebanese‐based survey

AbstractBackgroundDespite extensive research on sun protection, there remains a gap in certain populations like Lebanon. It is essential to assess how Lebanese adults handle sun exposure and its risks.ObjectivesTo examine the knowledge and habits of sun protection use among adults in Lebanon and explore the possible association between a history of skin cancer or photo‐related disorder and sun protection behaviours.MethodsWe conducted a single‐centre cross‐sectional study on 1001 patients presenting to the American University of Beirut Medical Center dermatology clinics from August 2020 till April 2023. Participants were between 18 and 80 years of age and recruited by convenience sampling. Those younger than 18 years old or not proficient in English or Arabic were excluded.ResultsAmong 1001 adults (mean age, 36.06 years [SD, 14.72]; 708 [71.08%] female), 512 (52.78%) use sunscreen, 449 (46.29%) do not and 9 (0.93%) do not know. Respondents with a history of a photo‐related condition (melasma, lentigos/freckles and rosacea) were significantly more likely to be sunscreen users (p &lt; 0.001), but a history of skin cancer did not significantly increase the odds of using sunscreen (odds ratio, 1.42; 95% confidence interval, 0.79–2.56). Participants who reported obtaining their sun protection information from dermatologists and/or social media were associated with increased sunscreen use.ConclusionsThe results of this cross‐sectional survey suggest that half of the patients presenting to dermatology clinics at a tertiary care centre in Beirut tend to use sunscreen. Future investigations are needed to better understand the photoprotective awareness and practices of the Lebanese population. The lack of patients' behaviours towards skin protection should gear a nation‐wide campaign to improve these practices. Our outcomes indicate that dermatologists should be at the forefront of such campaigns tackling sun‐protective measures and skin cancer prevention, especially using social media platforms.

British Association of Dermatologists national clinical audit on the management of Stevens-Johnson syndrome/toxic epidermal necrolysis in adults.

UK guidelines for managing adults with Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), published by the British Association of Dermatologists (BAD) in 2016, outline a set of audit standards. To audit current management of SJS/TEN in adults against standards in the BAD guidelines. BAD members were invited to submit data on five consecutive adults with SJS/TEN per department over an 8-week period in 2022. Thirty-nine dermatology centres in the UK (29%) participated, and data for 147 adults with SJS/TEN were collected. Within 24 h of the diagnosis being made or suspected, the following were documented, per 147 submitted cases: Severity-of-Illness Score for Toxic Epidermal Necrolysis (SCORTEN) for 76 (52%), list of medications for 113 (77%) and timelines for commencement/alterations of medications for 104 (71%). The initial assessment was documented of the eyes by an ophthalmologist in 71 (48%), of the mouth in 130 (88%), of the genital skin in 103 (70%) and of the urinary tract in 93 (63%). During the first 10 days after a suspected or confirmed diagnosis of SJS/TEN, daily assessments of the mouth were documented in 26 of 147 cases (18%), of the eyes in 12 (8%), and of the urinary tract and genital skin in 14 (10%). At discharge, a drug was declared to be the cause of SJS/TEN for 130 of 147 cases (88%), while 9 (6%) were thought to be secondary to infection. Eleven of 147 (8%) had no response to this question. Documentation regarding advice was present on avoidance of the culprit drug in 76 of 130 declared SJS/TEN cases (58%), and on requesting a MedicAlert® bracelet/amulet in 9 of the 147 cases (6%). This audit suggests that a clinical review checklist might be needed to enable colleagues to maintain standards outlined in the guidelines, including documentation of SCORTEN, daily assessments of mucosal areas, and advice to avoid culprit drug(s) and to request a MedicAlert® bracelet/amulet.
