Dermatologists' Perceptions of the Use of Teledermatology in Managing Hidradenitis Suppurativa: Survey Study.

BACKGROUND: The field of teledermatology has expanded tremendously and has been used for conditions including hidradenitis suppurativa (HS). However, due to the sensitive location of lesions, HS may be considered less suitable for teledermatology. OBJECTIVE: We sought to assess dermatologists' experiences and perceptions toward using teledermatology for HS relative to atopic dermatitis (AD) as a comparison. METHODS: A survey was disseminated electronically to practicing dermatologists in the Asia-Pacific region between February and June 2022. Differences in attitudes and perceptions between HS and AD were compared using random-effects ordered logistic regression, controlling for demographics. RESULTS: A total of 100 responses were obtained comprising of 76 (81.7%) dermatologists and 17 (18.3%) dermatology trainees; 62.6% (62/98) of physicians were uncomfortable with using teledermatology for HS. Multivariable regression confirmed increased perceived challenges with managing HS using teledermatology compared to AD. These challenges include the need for photography of hard-to-reach or sensitive areas (odds ratio [OR] 4.71, 95% CI 2.44-9.07; P<.001), difficulties in accurate assessment of severity (OR 2.66, 95%CI 1.48-4.79; P=.001), and inability to palpate lesions (OR 2.27, 95% CI 1.23-4.18; P=.009). CONCLUSIONS: This study confirms the relative reluctance of dermatologists to use teledermatology for HS and complements existing data showing mixed levels of willingness from patients. The use of teledermatology for HS may need to be optimized to overcome these challenges, including increasing security features, selection of patients with milder or limited diseases, and selecting patients with an established and strong doctor-patient relationship.

Knowledge, attitudes, and perceptions of hidradenitis suppurativa among young adults in Singapore.

Background: The prevalence of hidradenitis suppurativa (HS) is 0.00033% to 4.10% globally. Few epidemiological studies derive from Asia, with social stigmatization postulated to result in under-diagnosis. Objective: This study aimed to assess the self-reported prevalence of HS, and the knowledge, attitudes, and perceptions towards HS among Singaporean young-adults. Methods: A cross-sectional study (n = 158) was conducted by anonymous online questionnaire. The association between demographic factors and risk of potentially undiagnosed HS was evaluated using multivariable logistic regression. Differences between attitude-perception scores by demographic factors and knowledge of HS were tested using two-sample t-tests. Results: The prevalence of diagnosed and potentially undiagnosed HS was 0.63% and 8.9%, respectively. Non-Chinese had significantly higher social attitude-perception scores than Chinese (P = .029). Females had significantly higher social (P = .048) as well as economic and work (P = .037) attitude-perception scores than males. Those with knowledge of HS had significantly higher attitude-perception scores for interpersonal (P = .031) and social (P = .0052) subsections. Limitations: Small sample size, low frequency of HS cases, and self-reported prevalence may not generalize to the broader population in Singapore. Conclusion: Our results suggest a potential underdiagnosis of HS. Non-Chinese stigmatize HS less than Chinese, and females less than males. Individuals with knowledge of HS might be more open to interpersonal and social interactions with HS sufferers.

Malignancy-associated generalised exfoliative dermatitis: A retrospective study in a single-centre Asian cohort.

BACKGROUND: Erythroderma is an inflammatory skin condition that causes extensive erythema and skin scaling amounting ≥90% of the body surface area. This retrospective cohort study describes the prevalence of malignancy-associated erythroderma in a single centre where there was concerted effort to systematically offer malignancy screens to all adult erythroderma patients above the age of 65 years. METHODS: Clinical charts were reviewed for all adult inpatients and outpatients with erythroderma who attended the National University Hospital (NUH) from 1 July 2019 to 31 December 2021. Data collected included patient demographics, clinical findings, laboratory investigations, disease-specific investigations such as endoscopic procedures and biopsies, follow-up duration and mortality data. RESULTS: Seventy-four patients were analysed. The median age of the patients was 73 years old (interquartile range: 59-81 years old). An underlying dermatosis was the most common cause of erythroderma-63 patients having atopic dermatitis/asteatotic eczema or psoriasis. Three patients had erythroderma from drug eruptions, and 1 patient had chronic actinic dermatitis. Four patients had associated malignancies (5.4%). Half of our patients completed further evaluation for malignancy (52.7%). The rest had either declined or were eventually unable to complete the investigations. There was a higher prevalence of associated malignancy (7.8%) in elderly patients above 65 years old. CONCLUSION: When compared to existing literature, our cohort reflects a higher observed occurrence of malignancy in association with erythroderma. As delays in evaluation for underlying malignancy could result in potentially deleterious outcomes, it is prudent to consider systematic screening for malignancy in high-risk populations such as elderly erythroderma patients.

Factors influencing use and perceptions of teledermatology: A mixed-methods study of 942 participants.

BACKGROUND: The protracted COVID-19 pandemic highlights the need for a sustainable telemedicine practice. OBJECTIVE: To understand patient perceptions toward teledermatology. METHODS: Convergent parallel mixed-methods study of 942 dermatology patients or their caregivers between June 2020 and April 2021. RESULTS: Multivariate regression found that youth, increased computer use, willingness to show body areas over photo/video, perceived quality of teledermatology, demand for social distancing and to reduce commute were associated with willingness to use teledermatology. The willingness to use teledermatology declined with the easing of COVID-19 movement restrictions, and 48.5% reported a poorer experience with teledermatology than with in-person consultations. Qualitative data from 26 interviews showed that willingness to use is influenced by pragmatic considerations, emotional factors, and data privacy concerns. These were moderated by the patient's perception of disease severity and need for an accurate diagnosis. LIMITATIONS: Lack of data prior to the pandemic and during the initial lockdown period. CONCLUSION: The willingness to use teledermatology is influenced by circumstantial factors, technology literacy, views toward teledermatology, and factors driving the purpose of consultation. The declining willingness to use teledermatology with the easing pandemic, lower willingness to pay full in-clinic prices, and poorer experience compared with in-person consultations highlights the need to optimize this mode of delivery.

Steroid Phobia: Is There a Basis? A Review of Topical Steroid Safety, Addiction and Withdrawal.

There is a growing concern amongst patients about topical corticosteroid (TCS) side effects, with increasing discussion of topical steroid addiction (TSA) and topical steroid withdrawal (TSW) particularly on social media platforms. However, the acceptance of TSA/TSW as a distinct condition remains controversial within the dermatological community. We conducted a literature search using PubMed, MEDLINE, Cochrane Library, Google Scholar, Embase and Web of Science to identify original articles addressing TSA/TSW. We described the definition and reported clinical features of TSA/TSW including its classification into erythemato-edematous and papulopustular subtype. To assess the validity of TSA/TSW, we summarised and objectively appraised the postulated mechanisms for this condition, including tachyphylaxis, dysregulation of glucocorticoid receptors, rebound vasodilation and impaired skin barrier leading to a cytokine cascade. Understanding the evidence including its limitations and uncertainties highlights areas for future research and helps medical practitioners better counsel and provide care to patients who may be experiencing or who have concerns about TSA/TSW.

Supportive oncodermatology-a narrative review of its utility and the way forward.

Supportive oncodermatology is an interdisciplinary field, emerging due to increasing dermatological morbidity in patients with cancer and the recognition of the need for greater collaborative and integrated care to improve patient outcomes. These two unique fields (Oncology and Dermatology) may be integrated in various ways, such as through specialised combined clinics, protocols for expedited access, multidisciplinary groups and meetings, and the development of best practices guidelines. This narrative review consolidates the small but growing literature surrounding supportive oncodermatology; discusses the potential benefit and disadvantages, and areas for future research; and suggests a framework for implementation.

Appropriateness of blood culture: A comparison of practices between the emergency department and general wards.

BACKGROUND: The decision to perform a blood culture is influenced by factors, such as the pretest probability of bacteremia, resource availability and individual clinician's preference. The lack of formal guidelines results in inconsistencies in practices and an inappropriate or overuse of blood cultures. The primary aim of this study is to compare the rate of positive blood cultures in the emergency department (ED) and general ward. The secondary aim of this study is to analyze factors associated with a positive blood culture. METHODS: We compared 200 consecutive patients in the ED with 200 consecutive patients with first blood cultures done within 24 h of admission from ED to the general ward. We analyzed the clinical characteristics, proportion of positive blood cultures, and variables associated with a positive blood culture. RESULTS: The percentage of positive blood cultures was 13.5% (n = 27) in the ED group, compared with 6.0% (n = 12) in the general ward group. Contamination rates were higher in the ED compared to general ward (4% vs 0.5%). Heart rate and rigors were independently associated with a positive blood culture in a multivariate logistic regression model. CONCLUSION: There was a lower rate of positive blood cultures in the general ward group. Reasons may include a lower threshold for performing blood cultures in the general ward, and prior antibiotics in the ED reducing the sensitivity of blood cultures taken in the general ward. Adherence to clinical decision rules and education of junior staff are needed to improve the efficiency of blood culture taking practices.
