RESUMO
Population-wide skin cancer screening is not currently recommended in most countries. Instead, most clinical guidelines incorporate risk-based recommendations for skin checks, despite limited evidence around implementation and adherence to recommendations in practice. We aimed to determine adherence to personal risk-tailored melanoma skin check schedules and explore reasons influencing adherence. Patients (with/without a previous melanoma) attending tertiary dermatology clinics at the Melanoma Institute Australia, Sydney, Australia, were invited to complete a melanoma risk assessment questionnaire via iPad and provided with personal risk information alongside a risk-tailored skin check schedule. Data were collected from the risk tool, clinician-recorded data on schedule deviations, and appointment booking system. Post-consultation, we conducted semi-structured interviews with patients and clinic staff. We used a convergent segregated mixed methods approach for analysis. Interviews were audio recorded, transcribed and data were analysed thematically. Participant data were analysed from clinic records (n = 247) and interviews (n = 29 patients, 11 staff). Overall, there was 62% adherence to risk-tailored skin check schedules. In cases of non-adherence, skin checks tended to occur more frequently than recommended. Decisions to deviate were similarly influenced by patients (44%) and clinicians (56%). Themes driving non-adherence among patients included anxiety and wanting autonomy around decision-making, and among clinicians included concerns around specific lesions and risk estimate accuracy. There was moderate adherence to a clinical service program of personal risk-tailored skin check recommendations. Further adherence may be gained by incorporating strategies to identify and assist patients with high levels of anxiety and supporting clinicians to communicate risk-based recommendations with patients.
RESUMO
OBJECTIVE: We investigated the association between sun protection behaviours and demographic and melanoma risk characteristics of patients attending Australian melanoma specialist clinics. This may assist in targeting and tailoring melanoma prevention patient education for people at high-risk and specific population subgroups. METHODS: A cross-sectional analysis of questionnaire data collected from participants attending the dermatology clinics at two major melanoma centres in Sydney, Australia between February 2021 and September 2023. The primary outcome was Sun Protection Habits (SPH) index (a summary score measured as habitual past month use of sunscreen, hats, sunglasses, a shirt with sleeves that covers the shoulders, limiting midday sun exposure and seeking shade, using a Likert scale). The primary analysis considered the SPH index and its component items scored as continuous. RESULTS: Data from 883 people were analysed. Factors associated with less frequent sun protection behaviours overall included male gender, no personal history of melanoma, lower perceived risk, lower calculated 10-year risk of developing melanoma, and no private health insurance. People aged >61 years reported lower use of sunscreen but higher use of hats and sleeved-shirts compared with people in the younger age group. There was no difference in overall sun protection behaviours according to family history of melanoma, country of birth or by lifetime melanoma risk among people without a personal history of melanoma. CONCLUSIONS: These findings highlight the potential for targeting high-risk individuals with less frequent use of sun protection for patient education, public health messaging and ultimately improving sun protection behaviours.
RESUMO
PURPOSE: This study aimed to investigate the supportive care needs of Australian melanoma patients and their caregivers to form the basis for improving services. METHODS: General and melanoma-related supportive care needs in melanoma patients were measured using the SCNS-SF34 and SCNS-M12 respectively, whereas caregivers completed the SCNS-P&C. Patients also completed the MCQ-28 and FCRI-9, with all participants completing the QLQ-C30, DASS-21, and questions measuring utilisation and preference for supportive health services. Multivariable stepwise logistic regression was used to identify variables associated with unmet needs in melanoma patients. RESULTS: A total of 56 early-stage patients, 100 advanced-stage patients, and 37 caregivers participated. At least three-quarters ([Formula: see text] 75%) of each participant group reported at least one unmet need. Of the ten most reported unmet needs in each participant group, at least six ([Formula: see text] 60%) were related to psychological and emotional well-being, with access to a psychologist the most desired service (> 25%). Fear of cancer recurrence was equally prevalent in both patient groups at a level indicative of need for intervention. Advanced-stage patients reported significantly (p < 0.05) more unmet psychological, physical and daily living, and sexuality needs, and significantly (p < 0.05) worse functioning than early-stage patients. CONCLUSION: Australian melanoma patients and caregivers report substantial unmet supportive care needs, particularly regarding their psychological and emotional well-being. Psychological and emotional well-being services, such as access to a clinical psychologist or implementation of patient-reported outcome measures, should be incorporated into routine melanoma care to address unmet patient and caregiver needs and improve well-being.

Treatment with anti-PD1 inhibitors may enhance the risk for developing low grade squamoproliferative skin tumors. Immunohistochemical (IHC) analysis of the immune tumor microenvironment (TME) allows exploration of the pathogenesis and relationship with the PD1/PDL1 axis. Patients with eruptive keratoacanthoma (KA)-like lesions were recruited from the Melanoma Institute Australia, a tertiary referral specialist melanoma treatment center from January 2015 to August 2017. Clinicopathologic evaluation and IHC features of tumor cells (PDL1 expression) and peritumoral microenvironment (PD1, FOXP3, PDL1, CD4:CD8 expressing cells) in 12 eruptive KA-like lesions, were compared with solitary KAs in age and sex matched non-anti-PD1 treated controls. Four patients with repeated episodes of eruptive KA-like and lichenoid lesions developing 2-7 months after commencing pembrolizumab for AJCC stage IV melanoma, were recruited. Eruptive KA-like squamoproliferative lesions occurred in sun exposed sites and in areas of resolving, concomitant or delayed lichenoid reactions. Histologically, the lesions were well-differentiated squamoproliferative lesions resembling infundibulocystic squamous cell carcinoma or KA. IHC of cases and controls revealed low PDL1 expression of both squamous tumor cells and the TME immune cells. The numbers of immunosuppressive FOXP3 positive Tregs and PD1-expressing T-cells were higher in the cases than the controls but the CD4:CD8 ratio (2:1) was similar. The patients best responded to acitretin and were managed surgically if they demonstrated neoplastic features. Accelerated squamoproliferative growth in actinically damaged keratinocytes associated with lichenoid eruptions may be unmasked in patients treated with anti-PD1 immunotherapy potentially contributed to by a local cutaneous immunosuppressed TME.

Optical Coherence Tomography (OCT) is a useful non-invasive diagnostic tool for diagnosing and monitoring treatment of basal cell carcinomas. We describe the use of OCT in a patient with Basal Cell Naevus Syndrome. Through measuring tumour depth on OCT, management of individual tumours was triaged accordingly using 0.4 mm tumour depth as a cut-off for surgical and non-surgical management. OCT has potential to reduce unnecessary excisions and associated morbidity in this population of patients.

A 3.5-month-old boy presented with a changing medium-sized congenital melanocytic nevus on his leg. Due to atypical features on dermoscopy and reflectance confocal microscopy (RCM), an excision of the area of concern was performed. Histopathology showed many of the pathological features usually associated with a diagnosis of melanoma in situ in older patients, but due to the young age of the patient, absence of mitoses, and the degree of atypia, a diagnosis of a dysplastic compound nevus arising in a congenital compound (predominantly dermal) nevus was favored. In our case, RCM corresponded to histopathology helped target the area of concern and map the clinical and subclinical components to facilitate an optimal biopsy.

AI image classification algorithms have shown promising results when applied to skin cancer detection. Most public skin cancer image datasets are comprised of dermoscopic photos and are limited by selection bias, lack of standardization, and lend themselves to development of algorithms that can only be used by skilled clinicians. The SLICE-3D ("Skin Lesion Image Crops Extracted from 3D TBP") dataset described here addresses those concerns and contains images of over 400,000 distinct skin lesions from seven dermatologic centers from around the world. De-identified images were systematically extracted from sensitive 3D Total Body Photographs and are comparable in optical resolution to smartphone images. Algorithms trained on lower quality images could improve clinical workflows and detect skin cancers earlier if deployed in primary care or non-clinical settings, where photos are captured by non-expert physicians or patients. Such a tool could prompt individuals to visit a specialized dermatologist. This dataset circumvents many inherent limitations of prior datasets and may be used to build upon previous applications of skin imaging for cancer detection.

BACKGROUND: Diffuse melanosis cutis (DMC) is a rare presentation of metastatic melanoma characterized by a progressive blue-gray discoloration of the skin and mucous membranes. OBJECTIVE: To foster a better understanding of the clinical presentation, histological findings, and pathophysiology underlying DMC. METHODS: A systematic review of the literature was completed utilizing MEDLINE, CINAHL, Embase, and Google. Data were extracted using a protocol-driven spread sheet with all statistical analyses completed using SPSS. RESULTS: The review identified 68 original cases of DMC. The mean time from diagnosis of melanoma until development of DMC was 11.48 months (95% confidence interval [CI]: 0-48.16). The mean time to death following the onset of DMC was 4.43 months (95% CI: 0.00-11.11). Histological findings were relatively consistent demonstrating intracellular and extracellular melanin deposition in the dermis, with a pronounced perivascular distribution. The pathophysiological mechanisms underlying DMC could not be definitively elucidated; however, it is hypothesized that the melanin precursors, melanin, and melanosomes liberated by cytolytic metastatic melanoma deposits are phagocytosed by dermal histiocytes, manifesting clinically as diffuse melanosis. LIMITATIONS: The cross-sectional nature of case reports, paucity of cases of DMC, and heterogeneity in reporting limit any conclusions being drawn regarding the pathophysiology of DMC definitively. CONCLUSION: DMC heralds a poor prognosis for patients with metastatic melanoma and affected patients should be made aware of the implications of this condition on survival.

Midline mucinosis was observed in a 14-year-old man, which was confined to the midline of the back and appeared as asymptomatic, nonindurated, hyperpigmented plaques. Skin biopsies showed prominent interstitial mucinosis with perivascular lymphocytic infiltration. A literature review of plaque-like mucinosis revealed 14 previous cases with this distinct presentation that may overlap with reticular erythematous mucinosis and connective tissue disease. Midline mucinosis has been previously reported in prepubertal children but is rare.

RESUMO
INTRODUCTION: Fear of cancer recurrence (FCR) is commonly reported by patients diagnosed with early-stage (0-II) melanoma and can have a significant impact on daily functioning. This study will pilot the implementation of the Melanoma Care Program, an evidence-based, psychological intervention to reduce FCR, into routine practice, using a stepped-care model. METHODS AND ANALYSIS: Intervention effectiveness and level of implementation will be investigated using a hybrid type I design. Between 4 weeks before and 1 week after their next dermatological appointment, patients with melanoma will be invited to complete the Fear of Cancer Recurrence Inventory Short-Form, measuring self-reported FCR severity. Using a stepped-care model, clinical cut-off points will guide the level of support offered to patients. This includes: (1) usual care, (2) Melanoma: Questions and Answers psychoeducational booklet, and (3) three or five psychotherapeutic telehealth sessions. This longitudinal, mixed-methods pilot implementation study aims to recruit 108 patients previously diagnosed with stage 0-II melanoma. The primary effectiveness outcome is change in FCR severity over time. Secondary effectiveness outcomes include change in anxiety, depression, stress, health-related quality of life and melanoma-related knowledge over time. All outcomes are measured at baseline, within 1 week of the final telehealth session, and 6 and 12 months post-intervention. Implementation stakeholders at each study site and interested patients will provide feedback on intervention acceptability and appropriateness. Implementation stakeholders will also provide feedback on intervention cost, feasibility, fidelity and sustainability. These outcomes will be measured throughout implementation, using questionnaires and semistructured interviews/expert group discussions. Descriptive statistics, linear mixed-effects regression and thematic analysis will be used to analyse study data. ETHICS AND DISSEMINATION: Ethics approval was granted by the Sydney Local Health District-Royal Prince Alfred Zone (2020/ETH02518), protocol number: X20-0495. Results will be disseminated through peer-reviewed journals, conference presentations, social media and result summaries distributed to interested participants. TRIAL REGISTRATION DETAILS: (ACTRN12621000145808).

BACKGROUND: A range of interventions has been described for the treatment of pemphigus; however, the optimal therapeutic strategy has not been established. OBJECTIVE: We sought to evaluate the safety and efficacy of interventions for pemphigus vulgaris and pemphigus foliaceus. METHODS: We undertook a systematic review and meta-analysis according to the methodology of the Cochrane Collaboration. We selected randomized controlled trials including participants with the diagnosis of pemphigus vulgaris or pemphigus foliaceus confirmed with clinical, histopathological, and immunofluorescence criteria. All interventions were considered. Primary outcomes studied were remission and mortality. Secondary outcomes included disease control, relapse, pemphigus severity score, time to disease control, cumulative glucocorticoid dose, serum antibody titers, adverse events, and quality of life. RESULTS: Eleven studies with a total of 404 participants were identified. Interventions assessed included prednisolone dose regimen, pulsed dexamethasone, azathioprine, cyclophosphamide, cyclosporine, dapsone, mycophenolate, plasma exchange, topical epidermal growth factor, and traditional Chinese medicine. We found some interventions to be superior for certain outcomes, although we were unable to conclude which treatments are superior overall. LIMITATIONS: Many interventions for pemphigus have not been evaluated in controlled trials. All studies were insufficiently powered to establish definitive results. CONCLUSIONS: There is inadequate evidence available at present to ascertain the optimal therapy for pemphigus vulgaris and pemphigus foliaceus. Further randomized controlled trials are required.

BACKGROUND: The success of clinical trials in Epidermolysis Bullosa (EB) is dependent upon the availability of a valid and reliable scoring tool that can accurately assess and monitor disease severity. The Epidermolysis Bullosa Disease Activity and Scarring Index (EBDASI) and Instrument for Scoring Clinical Outcomes of Research for Epidermolysis Bullosa (iscorEB) were independently developed and validated against the Birmingham Epidermolysis Bullosa Severity Score but have never been directly compared. OBJECTIVE: To compare the reliability, convergent validity, and discriminant validity of the EBDASI and iscorEB scoring tools. METHODS: An observational cohort study was conducted in 15 patients with EB. Each patient was evaluated using the EBDASI and iscorEB-clinician scoring tools by 6 dermatologists with expertise in EB. Quality of life was assessed using the iscorEB-patient and Quality of Life in EB measures. RESULTS: The intraclass correlation coefficients for interrater reliability were 0.942 for the EBDASI and 0.852 for the iscorEB-clinician. The intraclass correlation coefficients for intrarater reliability was 0.99 for both scores. The two tools demonstrated strong convergent validity with each other. CONCLUSION: Both scoring tools demonstrate excellent reliability. The EBDASI appears to better discriminate between EB types and disease severities.
RESUMO
BACKGROUND: A range of interventions have been described for treatment of pemphigus, however the optimal therapeutic strategy has not been established. OBJECTIVES: To assess the efficacy and safety of all interventions used in the management of pemphigus vulgaris and pemphigus foliaceus. SEARCH STRATEGY: We searched the Cochrane Skin Group Specialised Register (October 2008), The Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2008), MEDLINE (2003 to October 2008), EMBASE (2005 to October 2008), LILACS (1981 to October 2008), Ongoing Trials Registers, reference lists of articles, conference proceedings from international pemphigus meetings and contacted experts in the field. SELECTION CRITERIA: Randomised controlled trials of any intervention in pemphigus vulgaris or pemphigus foliaceus. DATA COLLECTION AND ANALYSIS: Two authors independently assessed quality and extracted data from studies. All investigators were contacted for further information. Adverse events were identified from included studies. MAIN RESULTS: Eleven studies with a total of 404 participants (337 pemphigus vulgaris, 27 pemphigus foliaceus and 40 not specified ) were identified. The quality of included studies was not high, the majority of studies did not report allocation concealment, and power was limited by very small sample sizes. Interventions assessed included prednisolone dose regimen, pulsed dexamethasone, azathioprine, cyclophosphamide, cyclosporine, dapsone, mycophenolate, plasma exchange, topical epidermal growth factor and traditional Chinese medicine. Ten studies included participants with newly diagnosed or newly active recurrent disease, and one trial included participants in maintenance phase.There was sufficient data for 4 meta-analyses, each pooling results of two studies only. For the majority of interventions, results were inconclusive. We found some interventions to be superior for certain outcomes, although we were unable to conclude which treatments are superior overall. Mycophenolate was more effective in achieving disease control than azathioprine (1 study; n=40; RR 0.72; 95% CI 0.52 to 0.99, NNT 3.7). There was evidence of a steroid-sparing benefit of azathioprine (1 study; n=57; MWD -3919 mg prednisolone; 95% CI -6712 to -1126) and cyclophosphamide (1 study; n=54; MWD -3355 mg prednisolone; 95% CI -6144 to -566) compared to glucocorticoids alone. Topical epidermal growth factor decreased time to control (1 study; n=20; HR 2.35; 95% CI 1.62 to 3.41). AUTHORS' CONCLUSIONS: There is inadequate information available at present to ascertain the optimal therapy for pemphigus vulgaris or pemphigus foliaceus. Further research is required, especially to assess the optimal glucocorticoid dose, the role of adjuvant immunosuppressive medications, and long-term adverse events to improve harm:benefit analyses.
