Abstract
BACKGROUND Tazarotene has been extensively studied in clinical trials and is widely used to treat acne vulgaris (acne), with data suggesting that is one of the most potent topical retinoids. Irritation from the cream, foam, and gel formulations has limited its use in clinical practice. OBJECTIVE To assess the efficacy, safety, and tolerability of a unique tazarotene 0.045% lotion formulation based on polymeric emulsion technology in subjects with moderate or severe acne. Methods: A total of 1614 subjects, 9 years and older were randomized to receive tazarotene 0.045% lotion or vehicle in two identical double-blind, randomized, vehicle-controlled 12-week studies evaluating safety and efficacy (inflammatory [papules and pustules] and noninflammatory [comedonal] lesion counts and using Evaluator Global Severity Scores [EGSS]). Treatment success was defined as at least a 2-grade improvement in EGSS and ‘clear’/’almost clear’ and efficacy assessed through reduction in lesion counts. In addition, patients completed a validated Acne-Specific Quality of Life (Acne-QoL) questionnaire. Safety, adverse events (AEs), and cutaneous tolerability were assessed throughout. RESULTS Tazarotene 0.045% lotion demonstrated statistically significant superiority to vehicle in reducing inflammatory and noninflammatory lesion counts at week 12. Mean percent reductions in inflammatory and noninflammatory lesions were 55.5% and 51.4% (Study 1, both P<0.001 versus vehicle [45.7% and 41.5%, respectively]) and 59.5% and 60.0% (Study 2, both P<0.001 versus vehicle [49.0% and 41.6%, respectively]), with tazarotene 0.045% lotion at week 12. Treatment success was achieved by 25.5% (Study 1) and 29.6% (Study 2) of subjects treated with tazarotene 0.045% lotion (both P<0.001 versus vehicle [13.0% and 17.3%, respectively]). Improvements in QoL domain scores were consistently greater with tazarotene. Tazarotene 0.045% lotion was well-tolerated. The most common treatment-related AEs were application site pain (5.3%), dryness (3.6%), and exfoliation (2.1%). CONCLUSION Tazarotene 0.045% lotion provides statistically significant greater efficacy than vehicle in terms of lesion reduction and treatment success, with a highly favorable safety and tolerability profile in moderate-to-severe acne patients.

Abstract
BACKGROUND Surgical site infection (SSI) is the most common problem after surgery. Although several guidelines have indicated the efficacy of antiseptics, such as chlorhexidine-alcohol and povidone-iodine, in reducing SSI rate, the optimal recommendation is still not established. Olanexidine might have higher bactericidal activity than other antiseptic agents. However, no randomised study has evaluated the efficacy and safety of olanexidine over conventional antiseptics. We compared the effect of aqueous olanexidine and aqueous povidone-iodine on the incidence of SSI following clean-contaminated surgery. METHODS This was a multicentre, prospective, randomised, blinded-endpoint superiority trial for surgical skin antisepsis in clean-contaminated gastrointestinal and hepatobiliary pancreatic surgeries in four Japanese hospitals. Patients aged 20 years or older who underwent elective clean-contaminated wound surgery were randomly assigned in a 1:1 replacement ratio using a computer-generated block randomisation. Patients were randomly assigned to surgical skin antisepsis with an aqueous formulation of 1·5% olanexidine or surgical skin antisepsis with an aqueous formulation of 10% povidone-iodine before surgery. We used olanexidine in a ready-to-use applicator, and povidone-iodine was administered by a brush or by compression using pliers. Both antiseptics were applied from the papilla with a cranial limit and to the upper thigh with a caudal limit. The antiseptics were allowed to dry for 3 min, and then surgery started. Participants, some investigators, and data analysts were masked to treatment allocation. Participant enrolment was done by non-masked investigators. The primary outcome was 30-day SSI assessed in the intention-to-treat population. The surgical wound site of each participant was observed daily. After discharge, participants underwent at least one outpatient visit within 30 days after surgery. This trial is registered with University hospital Medical Information Network, 000031560. FINDINGS Between June 10, 2018, and April 18, 2019, 883 patients were assessed for eligibility. 587 patients were eligible and 294 received olanexidine and 293 received aqueous povidone-iodine before surgery. 30-day SSI occurred in 19 (7%) patients in the olanexidine group and 39 patients (13%) patients in the povidone-iodine group (adjusted risk difference -0·069; 90% CI -0·109 to -0·029; adjusted risk ratio [RR] 0·48, 90% CI 0·30 to 0·74; p=0·002). Five patients (2%) in the olanexidine group and five (2%) in the povidone-iodine group developed adverse skin reactions (adjusted RR 0·99, 95% CI 0·29 to 3·40; p=1·00). INTERPRETATION Olanexidine significantly reduced the occurrence of overall SSI and superficial incisional SSI compared with aqueous povidone-iodine in clean-contaminated surgery. Our results indicate that olanexidine might have a role to prevent SSI in patients who undergo clean-contaminated surgeries. FUNDING Keio University and Ohyama Health Foundation.

Abstract
INTRODUCTION Acne treatment guidelines suggest a combination approach with topical therapy including a topical retinoid, benzoyl peroxide and an oral antibiotic, or oral isotretinoin (OI), as first-line treatment options for severe acne vulgaris (AV). This study evaluated the efficacy and safety of a daily regimen of 0.3% adapalene and 2.5% benzoyl peroxide (0.3% A/BPO) gel and oral doxycycline 100 mg twice daily in severe (nonnodulocystic, non-conglobate) inflammatory AV.
METHODS This was a phase 4, 12-week, single-arm, openlabel, multi-center investigational study. Subjects (males and females, 12 or older, with severe inflammatory AV, Investigator Global Assessment [IGA] 4, and less than equal to 4 nodulocystic lesions, n=186) were considered OI candidates at baseline by the investigator. OI candidacy was re-evaluated at each study visit. Efficacy endpoints included inflammatory lesion (IL) reduction (week 12), IGA success (defined as IGA 0 [Clear] or 1 [Almost Clear], weeks 4, 8, and 12), percent reduction in lesions (weeks 4, 8, and 12), and subject questionnaires (week 12). Safety assessments included adverse events (AEs) and tolerability.
RESULTS Mean IL counts were significantly reduced from baseline to the end of the study (mean [SD]; baseline, 44.8 (21.73); week 12, 14.8 (16.11); mean percent reduction, 66.2% [30.47]; P less than .0001). By week 12, 37.1% of subjects achieved IGA Success (n=69, P less than .0001). Most subjects self-reported at least moderate improvement in AV (90.2%), and were "Satisfied" or "Very Satisfied" with the study treatment overall (83.2%). 41.9% of the subjects were no longer considered by their investigator to be OI candidates at week 4. At 12 weeks, only 19.9% were still considered OI candidates.
CONCLUSION 0.3% A/BPO + DOX is an effective and safe treatment option for severe inflammatory AV, before starting OI treatment, or as an alternative when OI cannot be used. ClinicalTrials.gov identifier: NCT02899000

Journal of drugs in dermatology : JDD. 2018;(4):426-441
Abstract
BACKGROUND/
OBJECTIVES Anti-aging strategies utilizing stem cells are in the forefront. Alpha and beta defensins are natural immune peptides that have been shown to activate an LGR6-positive stem cell locus in the hair follicle, identified as the source of most new epidermal cells during acute wound healing. We investigated the ability of biomimetic alpha and beta defensin molecules, supplemented with supportive cosmetic ingredients, formulated into three skin care products, at improving the structure and function of aging skin.
METHODS A participant- and investigator -blinded, placebo-controlled, multi-center trial was performed in outpatient settings. Forty-four healthy female subjects, aged 41-71 years, skin types I-V, completed the study with 2/3 receiving full formula and 1/3 receiving the placebo formula. A skin care regimen of 3 products (serum, cream, and mask) containing alpha-defensin 5 and beta-defensin 3, and other cosmetic ingredients, was applied to the face, post-auricular, and neck skin two times per day for 12 weeks in those receiving full formula, whereas the placebo group received the identically packaged regimen without the active ingredients. Methods of evaluation included histopathology and immunohistochemistry (7 subjects), clinical evaluation of pores, superficial and deep wrinkles based on Griffiths scale, and high-resolution photography (all subjects). In addition, a subset of 15 patients were evaluated with the QuantifiCare system (3-dimensional imaging and skin care scores for evenness, pores, oiliness) and Cortex measurements (high-resolution skin ultrasound, TEWL, elasticity, color, and hydration). Data points for evaluation included baseline, 6 weeks, and 12 weeks. All patients used the same sunscreen and cleanser, which was provided to them.
RESULTS The full formula regimen caused a significantly (P equals 0.027) increased thickness of the epidermis as seen in histology, not seen in the placebo group, with no signs of inflammation. No excessive cell proliferation was detected in either group as measured by Ki67-immunohistochemistry. Reduction in visible pores, superficial wrinkles, oiliness, pigmentation, and improvement of skin evenness, were statistically significant. A trend for improvement was also observed in skin elasticity, TEWL, and hydration; these did not achieve statistical significance. Ultrasound and histopathology demonstrated increases in dermal thickness in individual patients, without statistical significance. Comprehensive improvement in all 5 parameters, including visible pores, hyperpigmentation, superficial and deep wrinkles, and epidermal thickness, was statistically significant when the subset of participants assigned for histology in full formula group was compared with the placebo group participants.
CONCLUSIONS A 3-product skin care regimen containing alpha and beta defensins globally improves the visual appearance and structure of aging skin without irritation, dryness, or inflammation. Specifically, this regimen increases epidermal thickness, reduces appearance of pores, reduces wrinkles, and reduces melanin. This skin care regimen stimulates rejuvenation without evidence of increase of a marker of carcinogenic stimulation. This data is consistent with the hypothesis that a defensin-containing skin care regimen activates the body's own dormant stem cells to generate healthy new epidermal cells.

Abstract
BACKGROUND Fixed-combination calcipotriol 50 μg/g plus betamethasone 0.5 mg/g (Cal/BD) aerosol foam is a new topical treatment for psoriasis. Although moderate-to-severe psoriasis is typically treated with systemic/biologic therapies, a topical treatment that is efficacious in these patients may be a significant cost-saving alternative to systemic therapy. OBJECTIVE The objective of this study was to assess the response to Cal/BD foam and gel in patients with moderate-to-severe psoriasis enrolled in the phase III, 12-week PSO-ABLE study. METHODS Patients eligible for this analysis had moderate-to-severe psoriasis, defined by the 'Rule of Tens': body surface area ≥10% or Psoriasis Area and Severity Index (PASI) [excluding head; modified PASI (mPASI)] >10 or Dermatology Life-Quality Index >10. Endpoints included: proportion of patients achieving mPASI75 or mPASI90; change in body surface area; proportion of patients clear/almost clear with a ≥2 grade improvement (i.e., treatment success); change in Dermatology Life-Quality Index. RESULTS Seventy-seven Cal/BD foam patients and 82 gel patients had moderate-to-severe psoriasis. A greater proportion achieved mPASI75 and mPASI90 with Cal/BD foam than gel at weeks 4, 8, and 12 (57.1 vs. 35.4%; p = 0.006 and 15.6 vs. 12.2% at week 12, respectively); overall reduction in mPASI from baseline to week 12 was 64% with the foam vs. 51% with the gel. Overall reduction in body surface area at week 12 was 50% with the foam and 39% with the gel. Treatment success rates were higher with the Cal/BD foam than the gel at weeks 1, 2, 4, 8 (p = 0.0089), and 12, and a greater proportion of foam patients achieved a Dermatology Life-Quality Index score of 0/1 at weeks 4 (p = 0.004), 8, and 12 (p = 0.001). CONCLUSION Cal/BD foam can be considered as a treatment option in some patients with moderate-to-severe psoriasis who are potential candidates for systemic therapy. CLINICALTRIALS.

Abstract
BACKGROUND 13-Cis retinoic acid (13-CRA) is a synthetic vitamin A derivative. High-dose 13-CRA in patients with squamous cell cancers of the head and neck (SCCHNs) reduces the incidence of second primary tumors (SPTs). The authors report long-term results from a phase 3 randomized trial that compared treatment with low-dose 13-CRA versus placebo for patients who had early stage SCCHN, with a focus on the development of SPTs and overall survival (OS). METHODS In total, 176 patients who received treatment for stage I/II SCCHN were randomized to receive either low-dose 13-CRA (weight-based dose of 7.5 mg or 10 mg) or placebo for 2 years. A competing-risk approach and the log-rank test were used to compare the time to SPT and OS, respectively, between groups. RESULTS 13-CRA neither significantly reduced the cumulative incidence of SPT (P = .61) nor improved the time to SPT (hazard ratio [HR] for 13-CRA/placebo; 0.86; P = .61). Despite limited power, there was a trend toward improved OS for the 13-CRA arm (HR, 0.75; P = .14), particularly among patients whose index tumor was surgically excised (N = 26; HR, 0.50; P = .057) and among women (N = 39; HR, 0.44; P = .065) and never/former smokers (N = 129; HR, 0.61; P = .055), with a median follow-up of 16 years. The main 13-CRA related toxicities were dry skin and cheilitis. CONCLUSIONS Treatment with low-dose 13-CRA for 2 years did not decrease the incidence of SPT; subset analysis indicates a potential survival advantage among patients who are women and never/former smokers. More targeted interventions based on clinical risk factors and molecular characterization of tumors may yield greater success in future prevention trials.

Abstract
BACKGROUND Around two-thirds of patients with psoriasis do not adhere to topical treatment. The Topical Treatment Optimization Programme (TTOP), a five-element tool, includes guidance for the conversation between dermatologists/nurses and patients, patient information material, telephone/e-mail helpdesks and treatment reminders. It has been developed by patients and dermatologists to help increase adherence to treatment in psoriasis. OBJECTIVES To compare TTOP with standard of care ('non-TTOP') within a large European investigator-initiated study, PSO-TOP (clinicaltrials.gov NCT01587755). METHODS Patients with mild-to-moderate psoriasis received calcipotriol/betamethasone dipropionate gel as standardized study medication and were randomized 1 : 1 to either TTOP or non-TTOP management. Study medication was applied once daily for 8 weeks followed by 'as needed' application for an additional 56 weeks. Response was defined as a Physician's Global Assessment (PGA) of 'clear' or 'almost clear'. RESULTS In 1790 patients (full analysis set), response rates after 8 weeks (primary objective) were significantly higher for TTOP (36·3%) than for non-TTOP (31·3%, P = 0·0267). Better clinical outcome was accompanied by higher rates of patients feeling well informed about their skin condition, treatment and other factors related to adherence, but the Dermatology Life Quality Index was not statistically different. TTOP patients regarded the structured one-to-one conversations with their dermatologist/nurse as the most important element of TTOP. CONCLUSIONS Patients randomized to the TTOP intervention had a better clinical response than patients receiving standard of care. Improved communication between the healthcare provider and patient might be an important element in increasing adherence to topical therapy in psoriasis.

Abstract
BACKGROUND Psoriasis is a common, chronic, inflammatory skin disease with the majority of individuals having limited disease, treated with topical medication. However, special attributes of topical treatments like galenic/cosmetic properties or an inconvenient treatment schedule may result in low preference for topical treatments. Hence, there is strong medical need for a topical medication, which is highly efficacious, easy-to-use and preferred by both physicians and patients. OBJECTIVE Blinded interim analysis with the purpose to assess efficacy of (both from the physician's and patient's perspective) and the patients' preference with a highly efficacious and easy-to-use fixed combination of calcipotriol/betamethasone dipropionate topical gel after 8 weeks of once daily treatment in a large patient population. METHODS In this phase IV, international, multicentre, randomized, controlled, prospective, parallel group study, adult patients with active, mild to moderate psoriasis despite previous topical psoriasis treatment, i.e. unsuccessful in the 8 weeks preceding study participation, are followed over 64 weeks. During the first 8 weeks the patients apply their medication once a day followed by a 56-weeks maintenance period according to SmPC. Blinded interim analysis of all patients included demographics, Physician's Global Assessment, the novel Patient's self Global Assessment (PsGA) and Patient Preference Questionnaire (PPQ). RESULTS 1795 patients were analysed. At week 8, 36.5% of the physicians rated the patients' psoriasis as clear/almost clear. Similarly, based on the patients' self-assessment, 34.2% had a clear/almost clear score of PsGA in week 8. Analysis of the PPQ showed that the vast majority of the patients judged their 8-week treatment to be preferable compared with their previous treatments. CONCLUSION Results of this blinded interim analysis indicate that the fixed combination of calcipotriol/betamethasone dipropionate gel is highly efficacious and preferred by the majority of analysed patients.

Abstract
PURPOSE To report the efficacy of Hydrosorb® versus control (water based spray) as topical treatment of grade 1-2 radiodermatitis in patients (pts) treated for early stage breast cancer (BC) with normo fractionated radiotherapy (RT). PATIENTS AND METHODS BC pts were randomized to receive either Hydrosorb® (A) or water based spray (B). The primary endpoint was local treatment failure defined as interruption of RT because of skin radiotoxicity or change of local care because of skin alteration. Secondary endpoints were: evaluation of skin colorimetry, pain, quality of life. RESULTS Two-hundred seventy-eight pts were enrolled. There were 186 successfully treated pts. There were 60 "failures" in the Hydrosorb® arm, and 62 in the control arm (p=0.72), but mostly without interruption of the RT. Twenty-four pts stopped RT for local care. The average absolute reduction of colorimetric levels between day 28 and day 0 was 4 in the Hydrosorb®, and 4.2 in the water spray groups, respectively (p=0.36). Forty-eight patients in the Hydrosorb® arm had a VAS >2 versus 51 pts in the placebo arm, i.e. 34% and 38%, respectively (p=0.45). A significant reduction of pain was observed on D7 and D21 in the Hydrosorb® arm. CONCLUSIONS The present study showed no significant difference between Hydrosorb® and simple water spray in the treatment of acute radio-induced dermatitis even if there was a trend to an improvement in pain at the first weeks after the treatment. Systematic prevention measures and modern breast cancer radiotherapy techniques now allow excellent tolerability, but the place of topical treatment to optimize this tolerability has yet to be defined. It seems that the most important part of the skin care is the prevention of skin reactions using new adapted techniques, as well as strict hygiene.

Abstract
BACKGROUND Topical therapies are the mainstay of treatment for psoriasis vulgaris. The fixed combination of calcipotriol (Cal) 50 μg/g plus betamethasone 0.5 mg/g (as dipropionate; BD) is a first-line topical treatment and available as a gel or ointment. The use of these fixed combination products was compared in PRO-long, a long-term noninterventional study, for which interim results (4 and 12 weeks) have previously been reported. OBJECTIVE To describe and compare patients' perspectives on the fixed combination gel and ointment formulations; to include efficacy, adherence behaviour, treatment satisfaction and health-related quality of life (HRQoL) aspects during long-term real-life psoriasis management. METHODS PRO-long was a multicentre, prospective, observational, 52-week study of patients prescribed fixed combination Cal/BD gel or ointment in clinical practice. For final analysis the following were assessed at weeks 24, 36 and 52: differences in the proportion of patients with 'mild'/'very mild' disease according to patient's global assessment of disease severity, adherence behaviour, treatment satisfaction (nine-item treatment satisfaction questionnaire for medication) and HRQoL (Skindex-29). RESULTS Patients (n = 328) were prescribed once-daily Cal/BD gel (n = 152) or ointment (n = 176). At week 52, a higher proportion of patients reported that the severity of their psoriasis was 'mild'/'very mild' vs. baseline (gel: 60.2 vs. 47.1%; ointment: 58.8 vs. 42.4%), with greater treatment satisfaction reported in patients using gel vs. those using ointment. A higher proportion of patients found the gel 'easy' to use compared with the ointment (66.7 vs. 45.2%). Daily application of treatment took ≤ 5 min for 86.1% of patients using gel and 71.0% of patients using ointment. CONCLUSION This real-life study has demonstrated similar effectiveness between the Cal/BD formulations. However, over a 52-week treatment period, patients reported greater treatment satisfaction with the gel, which was considered easier to use, faster to apply and overall a more convenient product.
