Abstract
Adipokines are biologically active cytokines that are mainly produced in adipose tissue. There is evidence, in man and mice, that some adipokines may be secreted in other tissues including the vascular endothelium, epithelia and sebaceous glands. Moreover, modified serum levels of adipokines have been detected in people with acne vulgaris or psoriasis; it is suspected that adipokines could contribute to local and systemic inflammatory conditions. We aimed to evaluate the expression of three adipokines (i.e. leptin, adiponectin and resistin) in normal canine skin. Formalin-fixed, paraffin wax-embedded punch biopsy samples were obtained from the sparsely-haired skin of the caudal ventral abdomen of a single clinically healthy dog with no history of skin disease. Immunohistochemistry was applied, using rabbit polyclonal primary antibodies specific for leptin, adiponectin and resistin. Adipokines were not expressed in normal canine dermis or hypodermis. In contrast, they were detected in the keratinocytes of all epidermal layers and hair follicle segments, sebocytes, apocrine gland cells and in the vascular endothelium. This is the first report on the expression of adipokines in normal canine skin, a first step in studying their role in the skin physiology and inflammatory skin diseases of dogs.

Abstract
While the commensal bacterium Propionibacterium acnes (P. acnes) is involved in the maintenance of a healthy skin, it can also act as an opportunistic pathogen in acne vulgaris. The latest findings on P. acnes shed light on the critical role of a tight equilibrium between members of its phylotypes and within the skin microbiota in the development of this skin disease. Indeed, contrary to what was previously thought, proliferation of P. acnes is not the trigger of acne as patients with acne do not harbour more P. acnes in follicles than normal individuals. Instead, the loss of the skin microbial diversity together with the activation of the innate immunity might lead to this chronic inflammatory condition. This review provides results of the most recent biochemical and genomic investigations that led to the new taxonomic classification of P. acnes renamed Cutibacterium acnes (C. acnes), and to the better characterisation of its phylogenetic cluster groups. Moreover, the latest data on the role of C. acnes and its different phylotypes in acne are presented, providing an overview of the factors that could participate in the virulence and in the antimicrobial resistance of acne-associated strains. Overall, this emerging key information offers new perspectives in the treatment of acne, with future innovative strategies focusing on C. acnes biofilms and/or on its acne-associated phylotypes.

Abstract
Acne is an inflammatory and multifactorial skin disease. Different external and internal factors, including air pollution, aggressive skincare products, medication, mechanical, hormonal and familial factors and, more recently, lifestyle and stress, have been suggested as having an impact on acne. Moreover, for many years nutrition was believed to cause or worsen acne. Over the last decades, however, it has become a dermatological doctrine that there is no direct association between diet and acne. Even if recent research has allowed to identify certain nutritional elements and behaviour that may impact on acne, including the excessive intake of dairy products and hyperglycaemic food, modern lifestyle nutrition, obesity and eating disorders, knowledge about the role of nutrition in the physiopathology of acne still remains sparse and hypotheses and myths continue to dominate the debate. Thus, further clinical and translational research is necessary to investigate and confirm the association between nutrition and acne.

Abstract
PURPOSE The dermatological toxicity of cancer treatments is frequent and sometimes debilitating. Its reference classification, the NCI-CTCAE (National Cancer Institute-Common Terminology Criteria for Adverse Events), is sometimes difficult to use and does not include yet the newest toxicities. Our objective was to create a guide, TOXICAN, based on the CTCAE, which is easy to use in everyday practice and which facilitates the recognition and grading of these dermatological toxicities. METHODS This guide was developed by a working group ("GESTIM") comprising oncodermatologists, allergists, pathologists, and researchers from Nantes University Hospital. It was based on the dermatological toxicities found in the CTCAE and adapted to daily practice. These toxicities were grouped into categories and associated with photographs of typical cases to aid recognition. A simplified grading scale derived from the CTCAE was also created. This booklet was validated by means of user evaluation, and then the Delphi consensus method. RESULTS We selected 32 dermatological toxicities, including 12 created by our group, sorted into 7 categories: skin rash, dry skin/pruritus, hyperkeratotic papules, palmoplantar changes, hair and nail changes, mucosal changes, and others. Our simplified grading scale only differed from the CTCAE for one item, urticaria. Three items were modified after evaluation by the user group and 11 after application of the Delphi method. CONCLUSION The objective of our practical guide is to facilitate the use of the CTCAE for recognizing and grading dermatological toxicity of cancer treatments in order to provide optimal guidance for therapeutic adaptations. Its impact on clinical practice remains to be evaluated.

Abstract
Background In the coBRIM phase III trial, the addition of cobimetinib, an MEK inhibitor, to vemurafenib, a BRAF inhibitor, significantly improved progression-free survival [hazard ratio (HR), 0.58; P < 0.0001] and overall survival (HR, 0.70; P = 0.005) in advanced BRAF-mutated melanoma. Here, we report on the incidence, course, and management of key adverse events (AEs) in the coBRIM study. Patients and methods Patients were randomly assigned 1:1 to receive vemurafenib (960 mg twice a day) and either cobimetinib (60 mg once a day, 21 days on/7 days off) or placebo. In addition to standard safety evaluations, patients underwent regular ophthalmic, cardiac, and dermatologic surveillance examinations. Results Of 495 patients recruited to the study, 493 patients received treatment and constituted the safety population (cobimetinib combined with vemurafenib, 247; vemurafenib, 246). At data cut-off (30 September 2015), median follow-up was 18.5 months. Nearly every patient experienced an AE. In patients who received cobimetinib combined with vemurafenib, the frequency of grade ≥3 AEs was higher than in patients who received vemurafenib alone (75% versus 61%). Most AEs, including grade ≥3 AEs, occurred within the first treatment cycle. After the first cycle (28 days), the incidence of common AEs (rash, diarrhoea, photosensitivity, elevated creatine phosphokinase, serous retinopathy, pyrexia, and liver laboratory abnormalities) decreased substantially over time. Most AEs were managed conservatively by supportive care measures, dose modifications of study treatment, and, occasionally, permanent treatment discontinuation. Conclusions These data indicate that most AEs arising from treatment with cobimetinib combined with vemurafenib generally occur early in the treatment course, are mild or moderate and are manageable by patient monitoring, dose modification and supportive care.

Abstract
BACKGROUND Acne vulgaris is one of the main reasons for dermatological consultations. Severity and response to treatment may be impacted by various external factors or exposome. AIM To assess the impact of environmental factors on acne and to provide a comprehensive overview of the acne exposome. METHODS Two consensus meetings of five European dermatologists and a comprehensive literature search on exposome factors triggering acne served as a basis for this review. RESULTS Acne exposome was defined as the sum of all environmental factors influencing the occurrence, duration and severity of acne. Exposome factors impact on the response and the frequency of relapse to treatments by interacting with the skin barrier, sebaceous gland, innate immunity and cutaneous microbiota. They may be classified into the following six main categories: nutrition, psychological and lifestyle factors, occupational factors including cosmetics, as well as pollutants, medication and climatic factors. Moreover, practical considerations for the dermatologist's clinical practice are proposed. CONCLUSION Exposome factors including nutrition, medication, occupational factors, pollutants, climatic factors, and psychosocial and lifestyle factors may impact on the course and severity of acne and on treatment efficacy. Identifying and reducing the impact of exposome is important for an adequate acne disease management.
