RESUMO
BACKGROUND: The Psoriasis Longitudinal Assessment and Registry (PSOLAR) is a global, prospective, longitudinal, disease-based registry. It serves as a post-marketing safety commitment with a focus on patients with moderate to severe plaque psoriasis who are candidates for systemic therapy. OBJECTIVES: To describe the baseline disease demographics and clinical characteristics of a Canadian subgroup of participants enrolled in PSOLAR. METHODS: Baseline demographic/disease characteristics, medical histories, and previous psoriasis treatments for Canadian patients in PSOLAR were summarized using descriptive statistics. RESULTS: There were 1896 patients analyzed in the Canadian subgroup at 37 clinical sites, accounting for 15.7% of the global PSOLAR population. Baseline disease and clinical characteristics were as expected for a moderate to severe psoriasis population and were generally similar to the global PSOLAR population. Two distinctions were noted in the Canadian subgroup versus those enrolled globally: a higher proportion of patients were overweight/obese (84.7% vs. 80.4%) and male (61.4% vs. 54.7%). In addition, the Canadian subgroup had numerically higher historical peak disease activity (PGA score 3.35 vs. 3.1) and longer disease duration (22.3 years vs. 17.5 years). Canadian PSOLAR patients reported a variety of comorbidities, including psoriatic arthritis (31.5%), hypertension (34.6%), hyperlipidemia (24.3%), mental illness (24.1%), and inflammatory bowel disease (1.6%). CONCLUSION: The Canadian subgroup of PSOLAR patients was generally similar to those enrolled globally with respect to baseline disease demographics and clinical characteristics. Multiple comorbidities are noted in the Canadian subgroup, underscoring the need for a holistic approach to the treatment of psoriatic patients.

Acute generalized exanthematous pustulosis (AGEP) is a rare, acute, severe cutaneous adverse reaction mainly attributed to drugs, although other triggers, including infections, vaccinations, ingestion of various substances, and spider bites, have also been described. AGEP is characterized by the development of edema and erythema followed by the eruption of multiple punctate, non-follicular, sterile pustules and subsequent desquamation. AGEP typically has a rapid onset and prompt resolution within a few weeks. The differential diagnoses for AGEP are broad and include infectious, inflammatory, and drug-induced etiologies. Diagnosis of AGEP depends on both clinical and histologic criteria, as cases of overlap with other disease processes have been reported. Management includes removal of the offending drug or treatment of the underlying cause, if necessary, and supportive care, as AGEP is a self-limited disease. This review aims to provide an overview and update on the epidemiology, pathogenesis, reported precipitating factors, differentials, diagnosis, and management of AGEP.

Promotion in academia heavily relies on research productivity. The h-index is a standardized metric used to quantify research productivity at the individual level. We evaluated factors associated with h -index in dermatology across select Canadian academic centers with special focus on sex and academic rank. Medical academic centers throughout Canada with dermatology training programs were included. For each faculty member, we extracted the following data from public sources: sex, graduate degree, academic rank, years since the Fellow of the Royal College of Physicians and Surgeons of Canada (FRCPC) certification or equivalent, recent Canadian Institutes of Health Research (CIHR) funding and H-index (based on Scopus author profile). Log-linear univariate and multivariate regression analyses were performed to evaluate the association between h-index and these factors. An ordinal logistic regression was performed to explore sex differences in academic ranking. Our results showed that out of 300 faculty members across Canada, 155 were females (51.67%) and 145 were male (48.33%). H-index was available for 279 dermatologists. The average h-index was 8.35 (SD 11.53) and the median was 4.00 (1st quartile = 2.00, 3rd quartile = 10.00). Higher h-index was associated with more years since dermatology certification, successive academic rank, graduate degree and recent CIHR funding, but not with sex. In conclusion, h-index was not associated with sex when controlling for potential confounders. These results could reflect recent demographic changes in the field with an increase in newly appointed female dermatologists. Longitudinal assessment of academic productivity in dermatology is needed to assess the impact of continued efforts to promote equal opportunities in the field.
RESUMO
The rapid evolution of anti-cancer therapy (including chemotherapy, targeted therapy, and immunotherapy) in recent years has led to a more favorable efficacy and safety profile for a growing cancer population, and the improvement of overall survival and reduction of morbidity for many cancers. Anti-cancer therapy improves outcomes for cancer patients; however, many classes of anti-cancer therapy have been implicated in the induction of bullous dermatologic adverse events (DAE), leading to reduced patient quality of life and in some cases discontinuation of life-prolonging or palliative therapy. Timely and effective management of adverse events is critical for reducing treatment interruptions and preserving an anti-tumor effect. Bullous DAE may be limited to the skin or have systemic involvement with greater risk of morbidity and mortality. We present the epidemiology, diagnosis, pathogenesis, and management of bullous DAE secondary to anti-cancer therapies to enable clinicians to optimize management for these patients.
RESUMO
Reactive infectious mucocutaneous eruption is a recently distinguished mucosal-predominant blistering eruption triggered by respiratory infections. We describe a previously healthy 11-year-old Black female with rapidly progressive mucocutaneous blistering after prodromal respiratory infection symptoms. Reactive infectious mucocutaneous eruption was suspected and treated with systemic corticosteroids followed by etanercept. Twenty-four hours after etanercept, the diagnosis of multisystem inflammatory syndrome in children was raised and intravenous immunoglobulin was given. Rapidly worsening mucocutaneous disease ensued but was controlled by a second dose of etanercept. Our case highlights the following: (1) the novel observation of possible interaction/neutralization of etanercept by intravenous immunoglobulin, (2) the challenging differential diagnosis of multisystem inflammatory syndrome in children for reactive infectious mucocutaneous eruption patients in the Coronavirus disease 2019 (COVID-19) pandemic, and (3) the role of early treatment to prevent dyspigmentation.
RESUMO
Pediatric Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threating blistering diseases triggered by medications that affect the skin and mucosae. Drug-induced epidermal necrolysis is a better term for medication-triggered cases because there is a spectrum of disease severity that otherwise is divided into the separate entities of SJS, overlap SJS/TEN, and TEN. This manuscript reviews the management of drug-induced epidermal necrolysis (DEN), including diagnosis, investigations to exclude differential diagnoses, and treatment. Diagnosis of DEN relies on clinical features and a detailed medication history. The primary differential diagnosis is reactive infectious mucocutaneous eruption, which can be clinically distinguished by its disproportionate mucous membrane involvement relative to (sparse or absent) skin lesions. Identification and discontinuation of culprit medications is the mainstay of treatment of DEN. Early initiation of immunomodulatory therapy may prevent progression, reducing maximal disease severity and the risk of sequelae. A checklist approach to detailed management of DEN is proposed.

Drug reaction with eosinophilia and systemic symptoms (DReSS), also known as drug-induced hypersensitivity syndrome (DiHS), is a severe, systemic, T cell mediated drug reaction with combinations of cutaneous, hematologic, and internal organ involvement. Pathogenesis of DReSS is multi-factorial, involving drug-exposure, genetic predisposition through specific human leukocyte antigen (HLA) alleles and metabolism defects, viral reactivation, and immune dysregulation. Clinical features of this condition are delayed, stepwise, and heterogenous, making this syndrome challenging to recognize and diagnose. Two sets of validated diagnostic criteria exist that can be employed to diagnose DReSS/DiHS. Methods to improve early recognition of DReSS and predict disease severity has been a recent area of research focus. In vitro and in vivo tests can be employed to confirm the diagnosis and help identify culprit drugs. The mainstay treatment of DReSS is prompt withdrawal of the culprit drug, supportive treatment, and immunosuppression depending on the severity of disease. We present a comprehensive review on the most recent research and literature on DReSS, with emphasis on pathogenesis, clinical features, diagnosis, confirmatory testing modalities, and treatment. Additionally, this summary aims to highlight the differing viewpoints on this severe disease and broaden our perspective on the condition known as DReSS.
RESUMO
Infophobia, a term not being introduced in the medical literature, is one of many factors that may hamper a Patient-Health Care Provider (HCP) encounter. This phobia creates resistance to accepting medical knowledge, potentially becoming a significant barrier in medical practice, explained by patients' fear of information that may negatively impact medical assessments, therapies, and immunization. Since complications of this phobia are well beyond information, it should be recognized, and herein by presenting a dermatological case, we aim to establish this concept to identify this phenomenon.

OBJECTIVE: We determined the relative efficacy of non-surgical monotherapies for hidradenitis suppurativa (HS). METHODS: Network meta-analyses were conducted to determine treatments' surface under the cumulative ranking curve (SUCRA) value (i.e. an estimate that ranks efficacy); pairwise comparisons were conducted. RESULTS AND CONCLUSIONS: Ten trials were eligible for quantitative analyses; however, all did not have a common endpoint. Outcomes corresponded to pain severity, clinical response, quality of life and abscess count. For pain reduction, infliximab was ranked most efficacious (SUCRA = 94%) compared to bermekimab, anakinra and placebo; infliximab reduced pain more significantly (p < .05) than anakinra and then placebo. For the occurrence of clinical response, bimekizumab had the highest SUCRA (67%) relative to adalimumab, anakinra and placebo; bimekizumab was more efficacious than placebo (p < .05). For the quality of life in mild HS, Botox had the highest SUCRA (94%) compared to adalimumab and placebo; Botox was more efficacious than placebo (p < .05). For reduction in abscess count, oral tetracycline had the highest SUCRA (48%) compared to topical clindamycin and vehicle. Our work-being the first NMA study on non-surgical HS monotherapies-contributes to the comparative effectiveness literature for this condition.

BACKGROUND: Onychomycosis is an uncommon condition in children with increasing global prevalence. Health practitioners should confirm the diagnosis through mycology examination and examine family members of affected individuals for onychomycosis and tinea pedis. OBJECTIVE: To comprehensively summarize the treatment and management strategies for pediatric onychomycosis. METHODS: We performed a comprehensive literature search in the PubMed database to identify clinical studies on treatment for mycologically-confirmed dermatophyte onychomycosis in children <18 years. The exclusion criteria were combination therapy, case reports, reviews, systematic reviews and duplicate studies. RESULTS: Per-weight dosing regimens of systemic antifungal agents such as terbinafine, itraconazole, and fluconazole are found to be safe in children and are used off-label for the treatment of pediatric onychomycosis with high efficacy. Topical antifungal agents such as ciclopirox, efinaconazole, and tavaborole have established safety and efficacy in children. Children respond better than adults to topical therapy due to their thinner, faster growing nails. There is no data on the efficacy of medical devices for onychomycosis in children. CONCLUSION: Efinaconazole topical solution 10% and tavaborole topical solution 5% are FDA approved for the treatment of onychomycosis in children ≥6 years; ciclopirox topical solution 8% nail lacquer is approved in children ≥12 years.

There is an increase in the incidence of onychomycosis, especially in at-risk populations. Onychomycosis is difficult to treat, as the efficacy of most antifungal agents is relatively low. Nondermatophyte molds (NDMs) and mixed infection (dermatophyte plus NDM) onychomycosis are contributing to growing antifungal resistance, as they are often underestimated and ignored due to incorrect diagnosis. There is a need for a paradigm shift in the management of onychomycosis to a patient-centered, holistic approach with an emphasis on laboratory diagnosis prior to initiating treatment, which enables the rational choice of the antifungal agent. Additionally, in the case of resistant infections, antifungal susceptibility testing is recommended. Strategies for effective management of onychomycosis include disinfection of fungal reservoirs in shoes and socks and prophylaxis posttreatment using topical antifungal agents. These measures may reduce the recurrence of onychomycosis and improve long-term clinical success.
RESUMO
INTRODUCTION: The Biologics in Atopic Dermatitis: Experiences & Learnings (BADEL) project aims to improve real-life understanding of how, where, and when biologics can play a role in the treatment of atopic dermatitis (AD) from the perspective of healthcare professionals (HCPs) and patients. METHODS: Individual experiences of 24 patients with moderate-to-severe AD and who had been treated with biologic therapy (dupilumab) for ≥ 3-6 months, and 20 HCPs with a sub-specialty interest in AD were collected by means of focus groups held in Canada, Germany, France, Italy and the United Kingdom. Dupilumab was the only biologic therapy available at the time of the study. RESULTS: Most patients had suffered from AD for many years, particularly from itch and psychosocial issues, with AD negatively impacting all aspects of their life. They had experienced a long treatment journey and seen many dermatologists, enduring treatment delays and failures. They had been prescribed various therapies without long-term success. Biologics provided symptom improvement, offering many patients a near-normal quality of life. Side effects, especially conjunctivitis, were the greatest drawback, and there were a few issues with incomplete or unreliable efficacy. HCPs agreed that biologic therapy for AD in the majority of patients demonstrated rapid onset, good efficacy and tolerability, and are a viable option in patients who had exhausted all other treatment options. However, those patients who failed to sufficiently respond or developed intolerable adverse effects, particularly ocular symptoms, require alternative therapeutic options. CONCLUSION: Biologics can provide a near-normal quality of life for many patients with AD. Patients with AD who have failed conventional therapies should be offered all such novel therapies. Education and good patient-HCP communication will enable patients to manage their disease and treatment expectations. Patients and HCPs alike eagerly await alternative targeted therapies, which will offer greater choice and flexibility.
RESUMO
INTRODUCTION: Dupilumab is approved to treat moderate-to-severe atopic dermatitis (AD) in several countries in patients as young as 6 years of age. Since its approval, practical issues related to the use of dupilumab for AD have arisen, with particular interest in transitioning from current therapies and managing medication overlap, considerations for special populations of patients with AD, and management of potential adverse events. METHODS: This article aims to review the literature addressing several practical management issues related to dupilumab use for AD and to provide a framework for clinical decision-making in these circumstances and sub-populations. Each statement was reviewed, revised and voted on by authors to provide their level of agreement and degree of uncertainty for each statement. RESULTS: An agreement level > 80% was achieved for all of the statements. CONCLUSION: The expert panel provides statements considering the practical management of patients with AD taking dupilumab to inform clinical decision-making in specific but frequently encountered clinical situations.
RESUMO
BACKGROUND: Ultra high-frequency ultrasound (uHFUS) is a recently developed diagnostic technology. Despite its potential usefulness, no study has assessed its advantage in diagnosis and evaluation of hair disorders in comparison with other diagnostic methods. OBJECTIVES: To assess the practicability of uHFUS in diagnosing hair disorders and propose a diagnostic methodology. METHODS: Ultrasonographic images of scalp and forehead from patients with hair disorders (n = 103) and healthy controls (n = 40) were obtained by uHFUS and analyzed by both descriptive and numerical parameters. Furthermore, the data were compared with trichoscopic and histopathological findings. RESULTS: The pattern of inflammation and fibrosis, hair cycle abnormality, and the findings in subcutis were detected by uHFUS. Significant differences were noted in the numerical parameters associated with the number of hair shafts and follicles, hair diameters and their diversity, and dermal echogenicity in both cicatricial and non-cicatricial hair disorders. Findings in uHFUS were associated with those observed in trichoscopy and scalp biopsy but uHFUS was able to detect pathological findings associated with hair cycle, inflammation, fibrosis, and subcutaneous abnormalities, which are hardly assessable by trichoscopy. CONCLUSION: The findings of this study highlighted usefulness of uHFUS in diagnosing hair disorders, while overcoming the weaknesses and limitations of other diagnostic tools.
