Wound healing and microbiome, an unexpected relationship.

Skin wounds are common and represent a major public health and economical problem, with risks of complications and a significant negative impact on the quality of life of patients. Cutaneous wound healing is a tightly regulated process resulting in the restoration of tissue integrity. Wound healing involves the interaction of several skin, immune and vascular cells, growth factors and cytokines. However, external actors can play an important role in wound healing, such as the skin microbiome, which is the microbial commensal collection of bacteria, fungi and viruses inhabiting the skin. Indeed, recent advances have featured the interactions, within the wound environment, between different microbial species and between microbial species and the host immune system. This article reviews the relationship between the skin microbiome and the wound healing process. Although cutaneous wounds are a potential entry site for infection, the wound microbiome can have either a detrimental or a beneficial role on wound healing. Thus, targeting the skin microbiome could represent an essential part of wound healing management.

The impact of visible scars on well-being and quality of life: An international epidemiological survey in adults.

INTRODUCTION: Scars are visible marks from various causes, including surgery, skin injury, burning or dermatological disease, and may impact the quality of life. OBJECTIVE: To assess the impact of scars on quality of life (QoL). MATERIAL AND METHODS: Data about sociodemography, presence, origin, and symptoms of scars were collected using an Internet survey between April and May 2020. Overall, 11,100 individuals answered the survey. In total, 48.5% of the responders had at least one scar of less than 1 year of age. Scars were mainly reported on the abdomen and face. Globally, 28.9% of subjects with recent scars reported pain, 23.7% reported burning, 35.0% reported itching, and 44.1% reported redness. Subjects were most frequently bothered by the visibility of their scars and the presence of marks. Incidences were significantly higher than for those with older scars. The average DLQI score was 7.44; it decreased to 2.90 after 1 year. Subjects with scars aged less than 3 months had their QoL more frequently impacted (33.9%) than those with scars aged 12 months or more (10.2%). In subjects reporting skin discomfort, clinical symptoms significantly impacted body movement, choice of clothes, leisure activities, and sexual life more than in those reporting no skin discomfort. Moreover, subjects felt significantly more impacted in their daily lives due to their skin discomfort. When feeling bothered by the visibility of their scars, significantly more subjects were also impacted in their body movement, choice of clothes, leisure activities, and sexual life than those subjects who did not feel bothered. Moreover, significantly more subjects felt embarrassed. CONCLUSION: Scars significantly impact the subjects' quality of life. This impact is even more important when caused by recent and visible scars, with a lower DLQI score in subjects with more aged than in those with recent scars.

Expert recommendations on supportive skin care for non-surgical and surgical procedures.

A thorough knowledge of non-surgical procedures (laser, peelings, injections, threads) and surgical procedures (combined surgeries and skin grafts), including contraindications and potential risks and side effects, (e.g. infection, hypopigmentation, hyperpigmentation, and scarring) is essential to be able to reduce their incidence and ensure the patient receives the most benefit from the procedure. Individuals with darker skin and of high Fitzpatrick phototype are at higher risk of dyschromias, notably melasma and post-inflammatory hyperpigmentation, which may be treated using aesthetic procedures but may also arise as a complication of some procedures. A group of experts in cosmetic surgery and dermatology reviewed the published literature and discussed recommendations for optimizing outcomes with practical advice on supportive skincare before, during and after non-surgical or surgical procedures. A broad-spectrum sunscreen with a high sun protection factor against UVB and high protection against UVA, especially long UVA, is essential for all treatment modalities for the prevention and potential improvement of pigmentation disorders. Supportive skin care management to prepare, cleanse and protect the skin and post-procedure skin care with healing and anti-inflammatory ingredients are recommended to speed up regeneration and wound healing whilst minimizing scarring and downtime. Additionally, adjunctive skin care to procedures with antioxidant, anti-ageing and lightening properties may enhance skin benefits.

The Impact of Acne, Atopic Dermatitis, Skin Toxicities and Scars on Quality of Life and the Importance of a Holistic Treatment Approach.

Skin conditions such as acne, atopic dermatitis, skin toxicity from oncology treatment, and scars are among the most common health conditions and negatively impact quality of life (QoL). Yet the physician perception of this impact often varies greatly from the patient perception. This is important because patient illness perception is closely linked with seeking help and treatment adherence behaviors. The objective of this review is to better understand the impact of these four highly prevalent skin conditions on QoL including their health-related economic factors to improve treatment outcomes. The literature search included literature published on QoL with acne, atopic dermatitis, scars (from any cause) and skin toxicities on PubMed between 2015 and 2020. We found that patients with skin conditions have a much higher frequency of altered QoL and psychological distress than those without. Also, skin conditions negatively impact self-image and can cause feelings of isolation, loneliness, lower self-esteem, and lower body satisfaction. Additionally, physical discomfort adds to the psychological distress. These physical and psychological impacts are an enormous financial burden on patients, their families and society. We found evidence that holistic treatment including treating the skin condition itself, providing wider peer and psychological support as well as shared decision-making, therapeutic patient education and dermatologist involvement improves outcomes. Holistic history-taking, checklists, or the use of more formal QoL scoring tools can be incorporated into routine consultations to better assess patient well-being and provide clinicians with important information for adapting treatment to individual patient requirements. In conclusion, this review highlights the overall impact of skin conditions (including psychological and QoL impacts) and the importance of providing holistic care to optimize treatment outcomes. A comprehensive QoL screening tool would be useful to help provide patient-centered treatment.

Tacrolimus 0.1% versus ciclopiroxolamine 1% for maintenance therapy in patients with severe facial seborrheic dermatitis: A multicenter, double-blind, randomized controlled study.

BACKGROUND: No long-term maintenance therapy has been tested in patients with seborrheic dermatitis (SD). OBJECTIVE: We sought to compare the efficacy and tolerance of tacrolimus 0.1% ointment versus ciclopiroxolamine 1% cream as maintenance therapy for severe SD. METHODS: This double-blind randomized controlled study was conducted from 2014 to 2017 in 5 Dermatology Departments and 15 dermatology practices in France. Consecutive patients with severe and chronic facial SD were included. Patients were initially treated with desonide 0.05% cream twice daily for 7 days. Patients cleared after this open phase were randomized to receive tacrolimus 0.1% or ciclopiroxolamine 1% cream 2 times a week 24 weeks. The primary endpoint was disease-free-duration, defined as the time from randomization to first relapse. RESULTS: One hundred fourteen patients were randomized (tacrolimus, n = 57; ciclopiroxolamine, n = 57). Twelve patients relapsed in the tacrolimus group after a median delay of 91.5 days (range 15-195 days) versus 23 patients in the ciclopiroxolamine group (median delay, 27 days [range 13-201 days]). Comparison of disease-free duration curves showed that patients in the tacrolimus group had a longer duration of complete remission than those in the ciclopiroxolamine group (P = .018), corresponding to a hazard ratio of relapse of 0.44 (95% confidence interval 0.22-0.89; P = .022). LIMITATIONS: The theoretical sample size was not reached. CONCLUSION: Tacrolimus 0.1% is more effective than ciclopiroxolamine 1% as maintenance therapy for patients with facial SD.

A New Hydrocellular Wound Dressing Used After Dermatologic Surgery: Dermatologic Surgeons' and Patients' Perceptions.

BACKGROUND: Optimum postsurgical healing requires appropriate dressing use. OBJECTIVE: This study assessed effectiveness and tolerance of a novel, hydrocellular dressing in dermatologic surgery using validated tools, describing its use in clinical practice, and comparing surgeons' and patients' perceptions of scar evolution. METHODS: This study examined direct suture closures of surgical excisions of small- to medium-sized skin lesions on the extremities or trunk. Dressings were changed 3 times/week. The Vancouver Scar Scale (VSS) and the Patient and Observer Scar Assessment Scales (POSAS) were used to assess outcomes. Data were collected at Day 0 (D0, FLC application), Day 15 to 21 (D15-21, suture removal), and Day 45 (D45) postprocedure by the surgeon and the patient. RESULTS: There were 128 patients (mean age: 55.1 years, 56.1% women). Mean length and width of the excisions were 3.5 × 1.65 cm and the most common FLC applied was 8 × 8 cm (67.7%). Most scars had normal pigmentation, pliability, and height at D15 to 21 and D45, as reported by patients and surgeons using VSS. Patient scores on visual analog scale (VAS) were high (>8/10) and global satisfaction measured by POSAS was generally high (>7/10 at D15-21; >8/10 at D45). CONCLUSION: These dressings were effective in managing surgical excisions, as assessed by VSS, VAS, and POSAS. Further controlled studies investigating various dressings in wound repair are needed.

Role of betamethasone valerate 2.250 mg medicated plaster in the treatment of psoriasis and other dermatological pathologies: a review.

Treating dermatological pathologies with topical corticosteroids under occlusion is often more effective than nonocclusive therapy, especially in the treatment of psoriasis. Betamethasone valerate medicated plaster provides a controlled and localized method of dosing betamethasone valerate, a well-established corticosteroid with vasoconstrictive, anti-inflammatory, immunosuppressive, and antiproliferative properties. This self-adhesive plaster is approved for the treatment of inflammatory skin disorders that do not respond to treatment with less potent corticosteroids. As a patch, it offers all the clinical benefits of occlusive therapy such as increased penetration of topical agent into the area requiring treatment, enhanced skin hydration, and protection from local trauma or scratching. This translates into improved patient compliance, which is notoriously low in patients with dermatological conditions. This review presents the available clinical data from studies with betamethasone valerate medicated plaster in the treatment of psoriasis and other dermatoses and discusses its place in therapy for dermatological conditions.

Defining and recognising locally advanced basal cell carcinoma.

BACKGROUND: Rarely, basal cell carcinomas (BCCs) have the potential to become extensively invasive and destructive, a phenomenon that has led to the term "locally advanced BCC" (laBCC). We identified and described the diverse settings that could be considered "locally advanced". METHODS: The panel of experts included oncodermatologists, dermatological and maxillofacial surgeons, pathologists, radiotherapists and geriatricians. During a 1-day workshop session, an interactive flow/sequence of questions and inputs was debated. RESULTS: Discussion of nine cases permitted us to approach consensus concerning what constitutes laBCC. The expert panel retained three major components for the complete assessment of laBCC cases: factors of complexity related to the tumour itself, factors related to the operability and the technical procedure, and factors related to the patient. Competing risks of death should be precisely identified. To ensure homogeneous multidisciplinary team (MDT) decisions in different clinical settings, the panel aimed to develop a practical tool based on the three components. CONCLUSION: The grid presented is not a definitive tool, but rather, it is a method for analysing the complexity of laBCC.

Smoking and dietary factors associated with moderate-to-severe acne in French adolescents and young adults: results of a survey using a representative sample.

BACKGROUND: Dietary factors and smoking play a role in acne. METHODS: CSA Santé conducted a survey in France in 2012. Each individual answered a questionnaire to report acne, with associated epidemiological variables. Data on subjects between 15 and 24 years of age were extracted. The characteristics of subjects reporting acne were compared to subjects reporting no acne, using univariate and multivariate analysis. RESULTS: The daily consumption of chocolate and sweets was independently and highly associated with acne, with an odds ratio of 2.38 (95% CI: 1.31-4.31). Smoking more than 10 cigarettes a day was highly associated with no acne, with an odds ratio of 0.44 (95% CI: 0.30-0.66). The regular use of cannabis was associated with acne, with an odds ratio of 2.88 (95% CI: 1.55-5.37). CONCLUSION: Chocolate, sweets and cannabis smoking are associated with acne. We found tobacco to be protective. We failed to investigate the respective roles of sugar, lipids and milk.

Consequences of acne on stress, fatigue, sleep disorders and sexual activity: a population-based study.

Acne is a common disease among young people, which could have a serious impact on quality of life. Based on a survey using the quotas method on a large sample of the French population, we studied the impact of acne on feelings of stress, fatigue upon waking, sleep disorders and sexual activity. We did not establish any relationship to sleep disorders, but clearly ascertained that people with acne (n = 1,375) feel more stressed and have less sexual intercourse. Hence, 18% of people from acne group declared to be stressed every day (13.9% in control group) and 37.5% had no sexual intercourse (20.4% in control group; n = 891). To our knowledge, this is the first study to show that fatigue upon waking is strongly associated with the presence of acne (65.4% versus 58.4%). This study emphasises the fact that acne could have a deep resounding impact on the lives of people suffering from the disease.
