RESUMEN

Although cemiplimab has been approved for locally advanced (la) and metastatic (m) cutaneous squamous-cell carcinomas (CSCCs), its real-life value has not yet been demonstrated. An early-access program enrolled patients with la/mCSCCs to receive cemiplimab. Endpoints were best overall response rate (BOR), progression-free survival (PFS), overall survival (OS), duration of response (DOR) and safety. The 245 patients (mean age 77 years, 73% male, 49% prior systemic treatment, 24% immunocompromised, 27% Eastern Cooperative Oncology Group performance status (PS) ≥ 2) had laCSCCs (35%) or mCSCCs (65%). For the 240 recipients of ≥1 infusion(s), the BOR was 50.4% (complete, 21%; partial, 29%). With median follow-up at 12.6 months, median PFS was 7.9 months, and median OS and DOR were not reached. One-year OS was 73% versus 36%, respectively, for patients with PS < 2 versus ≥ 2. Multivariate analysis retained PS ≥ 2 as being associated during the first 6 months with PFS and OS. Head-and-neck location was associated with longer PFS. Immune status had no impact. Severe treatment-related adverse events occurred in 9% of the patients, including one death from toxic epidermal necrolysis. Cemiplimab real-life safety and efficacy support its use for la/mCSCCs. Patients with PS ≥ 2 benefited less from cemiplimab, but it might represent an option for immunocompromised patients.

RESUMEN

Importance: Understanding the contribution of the ugly duckling sign (a nevus that is obviously different from the others in a given individual) in intrapatient comparative analysis (IPCA) of nevi may help improve the detection of melanoma. Objectives: To assess the agreement of dermatologists on identification of the ugly duckling sign and estimate the contribution of IPCA to the diagnosis of melanoma. Design, Setting, and Participants: The same 2089 digital images of the nevi of a sample of 80 patients (mean age, 42 years [range, 19-80 years]; 33 men and 47 women), as well as 766 dermoscopic images from a subset of 30 patients (mean age, 40 years [range, 21-75 years]; 12 men and 18 women), were randomly presented to the same 9 dermatologists for blinded assessment from September 22, 2011, to April 1, 2013. The first experiment was designed to mimic an IPCA situation, with images of all nevi of each patient shown to the dermatologists, who were asked to identify ugly duckling nevi (UDN). The second experiment was designed to mimic a lesion-focused analysis to identify morphologically suspicious nevi. Data analysis was conducted from November 1, 2012, to June 1, 2013. Main Outcomes and Measures: Number of nevi labeled UDN and morphologically suspicious nevi, specificity of lesion-focused analysis and IPCA, and number of nevi identified for biopsy. Results: Of the 2089 clinical images of nevi from 80 patients (median number of nevi per patient, 26 [range, 8-81]) and 766 dermoscopic images (median number of nevi per patient, 19 [range, 8-81]), all melanomas were labeled UDN and as morphologically suspicious nevi by the 9 dermatologists. The median number of UDN detected per patient was 0.8 among the clinical images of nevi (mean, 1.0; range, 0.48-2.03) and 1.26 among the dermoscopic images (mean, 1.4; range, 1.00-2.06). The propensity to consider more or fewer nevi as having ugly duckling signs was independent of the presentation (clinical or dermoscopic). The agreement among the dermatologists regarding UDN was lower with dermoscopic images (mean pairwise agreement, 0.53 for clinical images and 0.50 for dermoscopic images). The specificity of IPCA was 0.96 for clinical images and 0.95 for dermoscopic images vs 0.88 and 0.85, respectively, for lesion-focused analysis. When both IPCA and lesion-focused analyses were used, the number of nevi considered for biopsy was reduced by a factor of 6.9 compared with lesion-focused analysis alone. Conclusions and Relevance: Intrapatient comparative analysis is of major importance to the effectiveness of the diagnosis of melanoma. Introducing IPCA using the ugly duckling sign in computer-assisted diagnosis systems would be expected to improve performance.

RESUMEN

The increasingly aged population worldwide means more people are living with chronic diseases, reduced autonomy, and taking various medications. Health professionals should take these into consideration when managing dermatological problems in elderly patients. Accordingly, current research is investigating the dermatological problems associated with the loss of cutaneous function with age. As cell renewal slows, the physical and chemical barrier function declines, cutaneous permeability increases, and the skin becomes increasingly vulnerable to external factors. In geriatric dermatology, the consequences of cutaneous aging lead to xerosis, skin folding, moisture-associated skin damage, and impaired wound healing. These problems pose significant challenges for both the elderly and their carers. Most often, nurses manage skin care in the elderly. However, until recently, little attention has been paid to developing appropriate, evidence-based, skincare protocols. The objective of this paper is to highlight common clinical problems with aging skin and provide some appropriate advice on cosmetic protocols for managing them. A review of the literature from 2004 to 2014 using PubMed was performed by a working group of six European dermatologists with clinical and research experience in dermatology. Basic topical therapy can restore and protect skin barrier function, which relieves problems associated with xerosis, prevents aggravating moisture-associated skin damage, and enhances quality of life. In conclusion, the authors provide physicians with practical recommendations to assist them in implementing basic skin care for the elderly in an integrated care approach.

RESUMEN

BACKGROUND: Psoriasis is a multifactorial disease involving both genetic predisposition and external triggers, resulting in epidermal and immune dysfunctions. Regardless of the severity of the disease, patients require additional basic topical treatment with emollients. Basic skin care products are well known for their role in moisture retention and symptom control in psoriasis, yet patients underuse them. Dry skin and cutaneous inflammation are associated with an impaired epidermal barrier function. This breakdown of the skin barrier causes the release of pro-inflammatory mediators that exaggerate inflammation. OBJECTIVES: to provide recommendations for the use of emollients (including ceramides, urea, keratolytic agents, zinc salts, niacinamide), thermal water and skin care products in psoriasis. METHODS: A review of the current literature from 2000 to 2012 using Medline and Ovid was performed by a working group of five European Dermatologists with clinical and research experience in psoriasis. RESULTS: Either alone or used adjunctively, basic topical therapy can restore and protect skin barrier function, increase remission times between flare-ups and enhance the effects of pharmaceutical therapy. CONCLUSION: We provide physicians with a tool to assist them in implementing basic skin care in an integrated disease management approach.

RESUMEN

Skin reactions due to radiotherapy and chemotherapy are a significant problem for an important number of cancer patients. While effective for treating cancer, they disturb cutaneous barrier function, causing a reaction soon after initiation of treatment that impacts patient quality of life. Managing these symptoms with cosmetics and nonpharmaceutical skin care products for camouflage or personal hygiene may be important for increasing patient self-esteem. However, inappropriate product choice or use could worsen side effects. Although recommendations exist for the pharmaceutical treatment of skin reactions, there are no recommendations for the choice or use of dermatologic skin care products for oncology patients. The present guidelines were developed by a board of European experts in dermatology and oncology to provide cancer care professionals with guidance for the appropriate use of non-pharmaceutical, dermocosmetic skin care management of cutaneous toxicities associated with radiotherapy and systemic chemotherapy, including epidermal growth factor inhibitors and monoclonal antibodies. The experts hope that these recommendations will improve the management of cutaneous side effects and hence quality of life for oncology patients.

RESUMEN

Although nevi are highly polymorphous, it has been suggested that each individual is characterized by only a few dominant patterns of nevi. Therefore, a nevus that does not fit in with these patterns, the "ugly duckling" nevus, is suspicious. Our objective was to study the intra-individual diversity of nevi, using human ability to build "perceived similarity clusters" (PSCs). Nine dermatologists had to cluster all the nevi of 80 patients into PSCs, at the clinical scale (CS) and at the dermoscopic scale (DS) (subset of 30 patients). Nine novices did the same in a subset of 11 patients. The experts identified a mean of 2.8 PSCs/patient at CS. Concordance was higher between experts than between novices at CS and at DS. Despite a trend for more PSCs at DS than at CS, the number of nevus patterns per patient remained low, regardless of the number of nevi. Inter-expert concordance permits a consensus representation of nevus diversity in each individual. Nevus diversity is limited in each patient and constitutes an individual reference system, which we can intuitively perceive. This reference is probably crucial for nevus analysis and melanoma detection and opens perspectives for computer-aided diagnostics.

RESUMEN

A case of multiple congenital epitrichial sweat gland hamartomas in a 2-day-old piglet is presented. The skin lesions were raised, ovoid to linear in configuration, alopecic, red-purple to pink, and cauliflower-like to cerebriform in appearance. Histological examination of skin specimens confirmed a diagnosis of epitrichial sweat gland hamartoma. Complete necropsy examination revealed no other lesions.
