The effect of a dermoscopy training programme on diagnostic accuracy and management decisions regarding pigmented skin lesions: a comparison between dermal therapists and general practitioners.

BACKGROUND: Dermoscopy is known to increase the diagnostic accuracy of pigmented skin lesions (PSLs) when used by trained professionals. The effect of dermoscopy training on the diagnostic ability of dermal therapists (DTs) has not been studied so far. OBJECTIVES: This study aimed to investigate whether DTs, in comparison with general practitioners (GPs), benefited from a training programme including dermoscopy, in both their ability to differentiate between different forms of PSL and to assign the correct therapeutic strategy. METHODS: In total, 24 DTs and 96 GPs attended a training programme on PSLs. Diagnostic skills as well as therapeutic strategy were assessed, prior to the training (pretest) and after the training (post-test) using clinical images alone, as well as after the addition of dermatoscopic images (integrated post-test). Bayesian hypothesis testing was used to determine statistical significance of differences between pretest, post-test and integrated post-test scores. RESULTS: Both the DTs and the GPs demonstrated benefit from the training: at the integrated post-test, the median proportion of correctly diagnosed PSLs was 73% (range 30-90) for GPs and 63% (range 27-80) for DTs. A statistically significant difference between pretest results and integrated test results was seen, with a Bayes factor > 100. At 12 percentage points higher, the GPs outperformed DTs in the accuracy of detecting PSLs. CONCLUSIONS: The study shows that a training programme focusing on PSLs while including dermoscopy positively impacts detection of PSLs by DTs and GPs. This training programme could form an integral part of the training of DTs in screening procedures, although additional research is needed.

Confidence of Irish dermatologists in caring for patients with skin of colour.

To assess Irish dermatologists' confidence with dermatology in patients with skin of colour (SOC), an online survey was distributed to all members of the Irish Association of Dermatology (IAD) by email. Half (50%) of respondents were 'not confident' or 'not at all confident' in diagnosing skin conditions and one-third (33.9%) were 'not confident' or 'not at all confident' in managing skin conditions in patients with SOC. Irish dermatologists have low confidence with skin pathology in SOC, and specific training could reduce this disparity.

Dermatological games: Part 1. Original description and critique.

'Dermatological games' by J. A. Cotterill was a seminal article published in 1981, which attempted to explain the interaction between dermatologists and patients using Berne's game theory. In Part 1 of this series of two reviews, we review Cotterill's original list of games and how they applied to dermatology in the context of when they were written. We then critically appraise Cotterill's article and arguments. Although the article was deliberately provocative, we found Cotterill's arguments to be well-structured and logical, and the 'games' described are well-conceived. Cotterill's candid analysis of doctors' motivations and the potential impact on the patient is refreshing and insightful. It is striking that, 40 years on, many of the original 'games' described remain recognizable in current practice. In Part 2, a list of new 'games' that might be observed in modern dermatological practice is introduced. The relevance of Cotterill's paper and an explanation for why his educational article remains relevant to dermatology practice and training today is scrutinized in order to stimulate discussion, promote education and improve patient care.

Dermatological games: Part 2. What has changed 40 years on?

In this two-part report, we review and critically appraise 'Dermatological games' by J. A. Cotterill, a seminal article published in 1981, which attempted to explain the interaction between dermatologists and patients using Berne's game theory. Part 1 described and critically appraised the educational value of Cotterill's original list of games in relation to how they apply to dermatology practice. In Part 2, a list of new 'games' that might be observed in current dermatological practice is introduced. The relevance of Cotterill's paper and an explanation for why his article remains relevant to dermatology practice and training today is scrutinized, in order to stimulate discussion and improve patient care.

Dermatologists' Perceptions and Confidence in Cosmetic Care for Male Patients.

BACKGROUND: Despite a growing interest in nonsurgical cosmetic procedures in men, the utilization of aesthetic treatments remains comparatively low, suggesting the presence of barriers to care. OBJECTIVE: To describe barriers to cosmetic intervention for male patients from the perspective of dermatologists. MATERIALS AND METHODS: An anonymous, online survey was distributed through a listserv made available by the American Academy of Dermatology. RESULTS: Dermatologist respondents perceived a low utilization of cosmetic services in male patients (5%) and a lack of opportunity (72.3%) to provide such services. Respondents also perceived a lack of sufficient education/training (40.9%), experience (20.5%), and a lack of evidence in the field (20.5%) for dermatologists as potential barriers to cosmetic care for male patients. Presence of targeted messaging and in-office educational materials for male patients was found to be associated with increased utilization of cosmetic treatments by male patients (p = .012, p = .012, respectively). Dermatologists reported strong confidence in delivering various noninvasive cosmetic treatments to male patients. CONCLUSION: Despite dermatologists' reported confidence in performing cosmetic procedures in men, many perceive insufficient education/training and experience with this population which may create barriers to cosmetic care for male patients. Increasing educational materials and targeted messaging to male patients may decrease barriers for patients to receive desired cosmetic care.

Changes in Chinese patch testing practices over 13 years: Updated cross-sectional survey and possible international implications.

BACKGROUND: Patch testing, the standard method for diagnosing allergic contact dermatitis, has been utilized for over 30 years in China. A 2006 survey found that patch testing was widespread among Chinese dermatologists, but the practice and perceptions were unsatisfactory. OBJECTIVE: To evaluate the current situation of patch testing practice and perception, we resurveyed Chinese dermatologists. METHODS: A cross-sectional survey of Chinese dermatologists was conducted by electronic questionnaires at the 15th National Congress of Dermatology in November 2019. RESULTS: There were 2199 valid questionnaires collected. About 75% of dermatologists performed patch testing; the majority (59.2%) utilized the baseline (standard) allergen series made in China; others used TRUE Test or the Chemotechnique Diagnostics series, a greater share compared with 2006. Most (92.8%) performed only one single reading, more than 2006. About two-thirds offered patient education after patch testing, but only 27% were executed by trained dermatologists. Dermatologists from regional hospitals more likely performed patch testing and had better perception of patch testing. The majority (88.1%) had received patch testing training, which however did not significantly improve dermatologists' perception. CONCLUSIONS: There was an insignificant improvement in practice and perception of dermatologists compared with 2006. Further education and studies should be conducted. Similar surveys in other countries would be of interest.

Improving care for delusional infestation patients: What can dermatologists learn from an entomologist?

Delusional Infestation (DI), represents one of the most difficult patient encounters that dermatology practitioners may experience. It is common for DI patients to doctor shop. Thus, dermatologists are one of several disciplines that may encounter DI patients in their practices. Others include veterinarians, epidemiologists, emergency departments, mental health practitioners, and entomologists. In this article, entomologist, Dr. Gale E. Ridge, with extensive DI experience, was interviewed to find out what an entomologist's perspective has been and what we, the dermatology providers, can learn from that. This is followed by a discussion by the dermatology experts on how the experience of entomologists compares to our experience and what we can learn from them.

Ex vivo full-field cellular-resolution optical coherence tomography of basal cell carcinomas: A pilot study of quality and feasibility of images and diagnostic accuracy in subtypes.

BACKGROUND: Studies have reported the application of conventional optical coherence tomography (OCT) in the diagnosis of basal cell carcinoma (BCC). The new OCT provides cellular details similar to those in pathology slides and may reduce user learning time. This study aimed to demonstrate the quality of ex vivo full-field cellular-resolution OCT images and compare the diagnostic accuracy between physicians with varying pathology experience. MATERIALS AND METHODS: Sixty histologically confirmed BCCs were selected. Tissue samples were sectioned and scanned using OCT, and their features were compared with those of hematoxylin and eosin (H&E)-stained sections. Thirty images were selected for the test administered to dermatology residents, dermatopathology fellows, and board-certified general pathologists without any OCT experience. The pretest learning included a 3-min instruction and 10-min self-study of four BCC variants. RESULTS: Histopathological BCC and normal histological features were clearly recognizable on the OCT images. The pathological BCC features observed in the OCT images correlated with those found in the H&E-stained sections. Seven participants completed the test. The correct answer rates of the residents, fellows, and pathologists were 71%, 68%, and 83% for BCC and 44%, 57%, and 57% for the BCC subtypes, respectively. CONCLUSION: All the participants identified BCC in >70% cases with a learning time of only 13 minutes. The results indicated that cellular-resolution OCT provided high-quality images similar to the conventional pathology slides. Pathology experience did reflect the diagnostic accuracy. However, a longer training time is still needed at all levels to recognize the BCC subtypes correctly.

Patient-focused Solutions in Rosacea Management: Treatment Challenges in Special Patient Groups

Rosacea is among the most common facial skin conditions diagnosed by dermatologists. Typical clinical features include erythema, flushing, telangiectasia, papules, and pustules distributed on the central face. While the prevalence of rosacea is highest among white populations of Northern European descent, recent reports have found that rosacea frequently occurs in people from a broad range of racial/ethnic backgrounds and skin types. When rosacea presents in darker skin types, the diagnosis is often more challenging due to masking of features by increased epidermal melanin. As such, under-diagnosis and underreporting may contribute to misconceptions about the prevalence of rosacea in populations with skin of color. Recognizing the unique presentations and complications associated with darker skin types is necessary to reduce the disparities in rosacea treatment, especially as the American population continues to become increasingly heterogeneous. Although rosacea is most common in middle-aged females, patients of other demographics may have more negative impacts on quality of life due to their disease. In this article, we review rosacea management with a focus on special patient groups: people with skin of color, and less common forms of rosacea, in order to diminish the physical and psychosocial burden of rosacea in all patient groups. Due to the variability inherent to rosacea, we advocate for an individualized, patient-centered approach to disease management.

The Current State of Dermatologists' Familiarity and Perspectives of Biosimilars for the Treatment of Psoriasis: A Global Cross-Sectional Survey.

BACKGROUND: Biologic patent expiration, accelerated approval pathways, and business interests of third party payers and the biopharmaceutical industry are driving the development of biosimilars to treat immune-mediated disorders like psoriasis. No studies have investigated dermatologists' familiarity and perspectives of biosimilars.

OBJECTIVES: To assess: (1) dermatologists' familiarity with biosimilars and interchangeability and (2) their perspectives toward biosimilar properties, including interchangeability, indication extrapolation, and immunogenicity risk.

METHODS: For this prospective survey study, we distributed electronic and paper questionnaires to dermatologists from selected societies and attendees at the 73rd annual American Academy of Dermatology meeting between March 20, 2015 and May 30, 2015. Primary outcome was dermatologists' familiarity with biosimilars. Secondary aims included dermatologists' confidence in biosimilar efficacy and safety, familiarity concerning the concept of interchangeability and perspectives regarding indication extrapolation, interchangeability, and immunogenicity risk.

RESULTS: Of the 116 total dermatologists who completed the questionnaire, 73 (62.9%) were slightly to very unfamiliar with biosimilars. On a 5-point Likert scale, dermatologists were somewhat to very concerned with the practice of interchangeability (3.4±1.1) and slightly uncomfortable to fairly comfortable in prescribing biosimilars for an extrapolated indication (3.3±1.0).

CONCLSUIONS: Our survey identified that the majority of dermatologists were unfamiliar with biosimilars. Dermatologists were consistently concerned regarding safety issues surrounding the practice of interchangeability without provider knowledge.

Maintenance of Certification: What's to Know.

The Maintenance of Certification (MOC) Program administered by the Royal College of Physicians and Surgeons applies to all Fellows of the Royal College including dermatologists. It is mandatory for those who wish to maintain their fellowship in the Royal College and can be critical for maintaining licensure requirements. Residents can take advantage of the program before becoming Fellows of the Royal College. Fellows and MOC Program participants in the Royal College MOC Program must complete a minimum of 400 credits during a 5-year cycle and a minimum of 40 credits in each year of the cycle. Credits are available for a wide range of CPD activities which the Royal College divides into three sections in its MOC Framework: Section 1, group learning; Section 2, self-learning; and Section 3, assessment. Many activities associated with involvement in Canadian Dermatology Association activities or involvement with the Journal of Cutaneous Medicine and Surgery (JCMS) are eligible for MOC Program credits. Failure to satisfactorily meet the requirements of the MOC Program in a 5-year cycle can result in loss of Fellowship in the Royal College.

Patch testing in Australia: Is it adequate?

BACKGROUND/OBJECTIVES: Patch testing (PT) is essential for making the diagnosis of allergic contact dermatitis (ACD). However, the extent of PT undertaken by Australian dermatologists is unknown. The objectives of this study were to determine the rate and type of PT in Australia, the perceived obstacles to PT, and to explore the exposure to PT in dermatology training. METHODS: Data were collected on private PT (analysing Medicare item numbers) and public hospital-based PT (estimated via verbal reports). An online survey on PT was sent to Fellows of the Australasian College of Dermatologists. RESULTS: It was found that total PT numbers, combining Medicare item number and public hospital data, were below the suggested optimum in all states and in Australia overall. Of the 173 respondents to the survey, 61% reported they patch tested and 78% reported they referred for PT. TrueTest was the most commonly used PT system, although it is known to be inadequate. Dermatologists who PT as registrars were significantly more likely to PT as consultants (P value = 0.0029). Cost, expertise required and staffing were considered major obstacles to performing PT. Accessibility and cost to the patient were common obstacles to referral. CONCLUSIONS: The combination of suboptimal PT rates and inadequate PT means that patients are missing out on being diagnosed with ACD in Australia. Increasing the exposure of registrars to PT, supporting specialised centres, the development of the Australian Baseline Series and the Contact Allergen Bank will, it is hoped, improve the rates of comprehensive PT in Australia.
