White patients' physical responses to healthcare treatments are influenced by provider race and gender.

The healthcare workforce in the United States is becoming increasingly diverse, gradually shifting society away from the historical overrepresentation of White men among physicians. However, given the long-standing underrepresentation of people of color and women in the medical field, patients may still associate the concept of doctors with White men and may be physiologically less responsive to treatment administered by providers from other backgrounds. To investigate this, we varied the race and gender of the provider from which White patients received identical treatment for allergic reactions and measured patients' improvement in response to this treatment, thus isolating how a provider's demographic characteristics shape physical responses to healthcare. A total of 187 White patients experiencing a laboratory-induced allergic reaction interacted with a healthcare provider who applied a treatment cream and told them it would relieve their allergic reaction. Unbeknownst to the patients, the cream was inert (an unscented lotion) and interactions were completely standardized except for the provider's race and gender. Patients were randomly assigned to interact with a provider who was a man or a woman and Asian, Black, or White. A fully blinded research assistant measured the change in the size of patients' allergic reaction after cream administration. Results indicated that White patients showed a weaker response to the standardized treatment over time when it was administered by women or Black providers. We explore several potential explanations for these varied physiological treatment responses and discuss the implications of problematic race and gender dynamics that can endure "under the skin," even for those who aim to be bias free.

Phase 3 Trials of Tirbanibulin Ointment for Actinic Keratosis.

BACKGROUND: The tubulin polymerization and Src kinase signaling inhibitor tirbanibulin is being investigated as a topical treatment for actinic keratosis, a precursor of squamous-cell carcinoma. METHODS: In two identically designed double-blind trials, we randomly assigned, in a 1:1 ratio, adults with actinic keratoses on the face or scalp to receive either topical tirbanibulin or vehicle (placebo) ointment. The ointment was applied by the patients to a 25-cm2 contiguous area containing four to eight lesions once daily for 5 consecutive days. The primary outcome was the percentage of patients with a complete (100%) reduction in the number of lesions in the application area at day 57. The secondary outcome was the percentage of patients with a partial (≥75%) reduction in the number of lesions within the application area at day 57. The incidence of recurrence was evaluated at 1 year. Local reactions were scored with the use of 4-point scale (ranging from 0 [absent] to 3 [severe]). RESULTS: A total of 702 patients were enrolled in the two trials (351 patients per trial). Complete clearance in trial 1 occurred in 44% of the patients (77 of 175) in the tirbanibulin group and in 5% of those (8 of 176) in the vehicle group (difference, 40 percentage points; 95% confidence interval [CI], 32 to 47; P<0.001); in trial 2, the percentages were 54% (97 of 178 patients) and 13% (22 of 173), respectively (difference, 42 percentage points; 95% CI, 33 to 51; P<0.001). The percentages of patients with partial clearance were significantly higher in the tirbanibulin groups than in the vehicle groups. At 1 year, the estimated percentage of patients with recurrent lesions was 47% among patients who had had a complete response to tirbanibulin. The most common local reactions to tirbanibulin were erythema in 91% of the patients and flaking or scaling in 82%. Adverse events with tirbanibulin were application-site pain in 10% of the patients and pruritus in 9%, all of which resolved. CONCLUSIONS: In two identically designed trials, tirbanibulin 1% ointment applied once daily for 5 days was superior to vehicle for the treatment of actinic keratosis at 2 months but was associated with transient local reactions and recurrence of lesions at 1 year. Trials comparing tirbanibulin with conventional treatments and that have longer follow-up are needed to determine the effects of tirbanibulin therapy on actinic keratosis.

Petroleum jelly: A comprehensive review of its history, uses, and safety.

Petrolatum, also known as petroleum jelly, is a widely used topical agent, with a variety of uses in dermatology. Despite its popularity, many myths surround this ubiquitous dermatologic staple. This review details the history of petrolatum and how it is manufactured as well as how its biologic properties make it a great moisturizer. Additionally, data on its potential for flammability, allergenicity, and comedogenicity are detailed, dispelling misconceptions about petrolatum use around oxygen and as a cause of acne. The uses and benefits of petrolatum in dermatology are wide-ranging-a patch test instrument, a vehicle for medicated ointments, and a wound care essential. Given its ubiquitous presence, it is important for dermatologists to understand the history, safety profile, and myths surrounding this humble skincare staple.

Efficacy and safety of crisaborole ointment, 2%, in participants aged ≥45 years with stasis dermatitis: Results from a fully decentralized, randomized, proof-of-concept phase 2a study.

BACKGROUND: Crisaborole ointment, 2%, is a nonsteroidal topical phosphodiesterase 4 inhibitor approved for the treatment of mild-to-moderate atopic dermatitis. OBJECTIVE: To evaluate the efficacy and safety of crisaborole in stasis dermatitis (SD). METHODS: In this randomized, double-blind, vehicle-controlled, decentralized phase 2a study (NCT04091087), 65 participants aged ≥45 years with SD without active ulceration received crisaborole or vehicle (1:1) twice-daily for 6 weeks. The primary end point was percentage change from baseline in total sign score at week 6 based on in-person assessment. RESULTS: Crisaborole-treated participants had significantly reduced total sign score from baseline versus vehicle based on in-person (nondermatologist) assessment (-32.4% vs -18.1%, P = .0299) and central reader (dermatologists) assessment of photographs (-52.5% vs -10.3%, P = .0004). Efficacy according to success and improvement per Investigator's Global Assessment score and lesional percentage body surface area reached statistical significance based on central reader but not in-person assessments. Skin and subcutaneous tissue disorders were common all-causality treatment-emergent adverse events with crisaborole. LIMITATIONS: Small sample size and short treatment duration were key limitations. In-person assessment was not conducted by dermatologists. CONCLUSION: Crisaborole improved signs and symptoms of SD and was well tolerated. Central reader assessment represents a promising approach for siteless clinical research.

Effectiveness and tolerability of rectal ointment and suppositories containing sucralfate for hemorrhoidal symptoms: a prospective, observational study.

BACKGROUND AND AIMS: A high number of topical products are available for the treatment of hemorrhoidal symptoms. Sucralfate-based topical products constitute a new treatment alternative that act as a mechanical barrier to facilitate healing. The aim of this prospective, observational study was to determine patient- and physician-assessed effectiveness and tolerability of rectal ointment and suppositories containing sucralfate for the treatment of hemorrhoidal symptoms in routine clinical practice. METHODS: Adult patients with diagnosed, mild-to-moderate, symptomatic non-bleeding hemorrhoids treated with rectal ointment or suppositories containing sucralfate were enrolled. Patients were administered treatment twice per day for at least 1 week until symptom resolution and/or for a maximum of 4 weeks. The primary endpoint was patient-assessed effectiveness on a modified Symptom Severity Score (mSSS, range 0 to 14). Physician-assessed effectiveness (9 symptoms, 0 to 5 Likert scale), hemorrhoid grade, and patient satisfaction were also determined. RESULTS: Five investigators enrolled 60 patients; mean age was 48.4 ± 16.6 years and 72.4% were female. Pain or pressure sensitivity was reported as the most severe symptom by patients, and pressure sensitivity, discharge, soiling, and prolapse by physicians. Mean patient-assessed mSSS at baseline was 6.6 ± 1.9 and was significantly improved overall and in the ointment and suppository groups individually by -4.6 ± 2.0, -4.4 ± 1.8, and -4.8 ± 2.2, respectively (p < 0.0001). Investigator-assessed mean baseline symptom score was 18.1 ± 3.9 and improved by -7.1 ± 4.5, -6.9 ± 5.4, and -7.3 ± 3.5, respectively (p < 0.0001). Investigator-assessed symptoms of pressure sensitivity, swelling, and discharge were improved to the greatest extent. Hemorrhoid grade was improved in 38% of patients at the end of treatment. Compliance with treatment was 97.4% and patient satisfaction with application and onset of action was high (81.3% and 76.2%, respectively). Both the ointment and suppository were well tolerated. CONCLUSIONS: The effectiveness of topical ointment or suppository containing sucralfate on patient- and investigator-assessed hemorrhoidal symptoms in real-life clinical practice was demonstrated. Patient satisfaction was high and treatments were well tolerated. Larger controlled trials are warranted to confirm the results.

Histopathologic findings in ointment pseudo-cheilitis: An alert to dermatopathologists.

Ointment pseudo-cheilitis is a recently recognized distinctive type of self-induced cheilitis. Lesions consist of a variable amount of crusts adhered to the vermilion. These crusts consist of dried saliva and dead cells mixed with applied medications attached to the lip surface. Patients are typically severely anxious or depressed; the condition impacts quality of life. Ointment pseudo-cheilitis is frequently misdiagnosed as exfoliative cheilitis or cheilitis glandularis. Biopsy reports are often non-revealing because there are no established histopathological criteria for this disease, and clinicians usually do not formulate the correct diagnostic hypothesis. Here, we present the histopathological findings of four cases of ointment pseudo-cheilitis. The most consistent finding was the presence of laminated parakeratotic material detached from the epithelium in biopsies that are devoid of other significant diagnostic changes. This material at the lip surface possibly represents physiologic labial desquamation mixed with dried saliva and applied medication. With this report, we intend to alert dermatopathologists to the diagnosis of ointment pseudo-cheilitis if they receive biopsies from patients who present clinically exuberant labial lesions that show only minimal histopathological changes.

Preclinical pharmacokinetic investigation of the bioavailability and skin distribution of HY-072808 ointment, a novel drug candidate for the treatment of atopic dermatitis, in minipigs by a newly LC-MS/MS method.

HY-072808 is a novel phosphodiesterase 4 inhibitor clinically used for topical atopic dermatitis treatment. Cytochrome P450 enzymes are involved in transforming it into major metabolite ZZ-24. An efficient UPLC-MS/MS method was established to detect HY-072808 and ZZ-24 in plasma and skin tissues of minipigs.One-step protein precipitation was performed with acetonitrile. Subsequently, elution was served with a methanol and water gradient containing 0.1% formic acid for 3.5 min. The plasma and skin tissue concentrations of HY-072808 and ZZ-24 showed good linearity from 0.200 to 200 ng/mL.The experimental minipigs exhibited low systemic exposure and bioavailability of 3.1-7.6% after transdermal application of 1-4% HY-072808 ointment. Multiple topical administrations over seven consecutive days showed a minor accumulation in systemic exposure, with accumulation factors of 2.3 and 4.0 for HY-072808 and ZZ-24, respectively.The distribution of HY-072808 ointment among different cortical layers in minipigs was studied for the first time. Following transdermal application of 2% HY-072808 ointment, the concentration in plasma and skin tissues in the order of epidermis > dermis > subcutaneous tissue ≈ subcutaneous muscle ≈ plasma; at 48 h after the administration, the epidermis and dermis still had a high concentration of the drug.

Topical ivermectin ointment treatment of Demodex blepharitis: a 6-year retrospective study.

BACKGROUND: To evaluate the efficacy of topical ivermectin 1% ointment, for the treatment of Demodex blepharitis. METHODS: A retrospective study was designed to review electronic medical records of patients seen between January 2017 and December 2022, who had a diagnosis of Demodex blepharitis, treated with topical ivermectin 1% with at least 6 months of follow-up (Centro de Ojos Quilmes, Buenos Aires, Argentina). The presence of collarettes was graded from 0 to 4. An imaging system (Keratograph) was used, to evaluate tear meniscus height (TMH), non-invasive tear break-up time (NIKBUT), and degree of conjunctival redness. In addition, the ocular surface disease index (OSDI) test was performed. Results were compared before and after ivermectin treatment, which was performed once a day for 2 months. RESULTS: A total of 2157 patients (4314 eyes) were included. The mean age was 50.43 ± 15.3 years, and the follow-up time was 26.1 ± 8.5 months. No one discontinued treatment due to intolerance, although 14 cases (0.6 %) reported occasional discomfort. The grade of collarettes decreased with statistical significance, from 3.37 ± 0.7 to 0.1 ± 0.3 (p < 0.01), as well as conjunctival redness from 1.32 ± 0.3 to 0.94 ± 0.4 (p < 0.01) and OSDI score from 58.74 ± 17.9 to 17.1 ± 10.5 (p = 0.02). TMH and NIKBUT improved without statistical difference. CONCLUSION: Treatment with ivermectin 1% topical ointment, once daily for 2 months, was effective in reducing the presence of collarettes and in improving symptoms in patients with Demodex blepharitis.

Parent satisfaction with lotion, cream, gel and ointment emollient types: secondary analysis of the Best Emollients for Eczema study.

BACKGROUND: The main determinant of emollient effectiveness is whether it is used, which in turn is linked with user satisfaction. OBJECTIVES: To compare parental satisfaction with emollient type for the treatment of childhood eczema. METHODS: Secondary analysis of data from the Best Emollients for Eczema (BEE) trial was undertaken. In total, 550 children aged between 6 months and 12 years were recruited from primary care in England and randomized to use a lotion, cream, gel or ointment as their main emollient for 16 weeks. At week, 16 parents were asked to complete an Emollient Satisfaction Questionnaire (ESQ). Completion rates and scores were compared, using χ2 test, t-test calculations and one-way Anova as appropriate. RESULTS: Data on 378 participants (68.7% of those randomized) were analysed. Mean ESQ scores were gel 20.9 (SD 5.3), lotion 20.4 (SD 5.6), cream 18.8 (SD 6.3) and ointment 15.2 (SD 6.8) (P < 0.001). In pairwise comparisons, there was a statistically significant difference in mean ESQ scores between ointment and lotion (P < 0.001), ointment and cream (P < 0.001) and ointment and gel (P < 0.001) but not between lotion, cream and gel. Participants using lotions had highest overall satisfaction and were most likely to continue using their emollient. ESQ scores were correlated with reported emollient use and improvements in parent-reported eczema severity. CONCLUSIONS: Overall, lotions and gels were favoured over creams and ointments. Although satisfaction is determined by personal preference, these results will aid parents, clinicians and children to find the right emollient(s) for them.

Comparison of the clinical efficacy of topical tretinoin 0.05% cream and tacrolimus 0.1% ointment plus iontophoresis in the management of palmoplantar psoriasis.

BACKGROUND: Palmoplantar psoriasis (PPP) is a localized variant of psoriasis that may be resistant to topical therapy, owing to the poor penetrability of topical agents at this anatomical site. Modalities that enhance localized cutaneous delivery of drugs could help to solve this problem. Iontophoresis is one such procedure that augments transdermal drug delivery, thus enabling better and expeditious therapeutic outcomes. OBJECTIVE: To compare the therapeutic efficacy and safety of iontophoresis with tretinoin 0.05% cream and tacrolimus 0.1% ointment in treating patients with PPP. METHODS: Sixty patients with PPP (28 males and 32 females, age range 8-76 years) were enrolled and randomly assigned to one of two groups comprising 30 patients each. One group (12 males and 18 females) received iontophoresis with tretinoin 0.05% cream; the other (16 males and 14 females) received iontophoresis treatment with tacrolimus 0.1% ointment. Both groups received treatment weekly from baseline until 4 weeks and then fortnightly at weeks 6 and 8. Clinical images were taken at each visit and improvement of psoriasis was evaluated using the erythema, scaling, induration and fissuring (ESIF) score. The percentage reduction in ESIF score was also assessed on completion of treatment and the grade of improvement noted for each patient. RESULTS: Twenty-seven patients in the iontophoresis with tretinoin 0.05% cream group and 29 in the iontophoresis treatment with tacrolimus 0.1% ointment group completed the study. The mean (SD) ESIF score in the former decreased significantly from 8.7 (2) at baseline to 3.2 (1.7) at the study endpoint (P < 0.001). Similarly, in the latter group, there was a substantial reduction in mean (SD) ESIF score from 8.2 (1.9) at baseline to 3.3 (1.1) at the study end (P < 0.001). No significant adverse effects were encountered in either treatment arm. CONCLUSIONS: Iontophoresis using tretinoin and tacrolimus was found to be effective and safe for the treatment of PPP. Although iontophoresis with tretinoin showed slightly better results than with tacrolimus, these were not statistically significant.

Clinical features and comprehensive treatment of persistent corneal epithelial dysfunction after cataract surgery.

OBJECTIVE: Evaluation of clinical efficacy and safety of tobramycin/dexamethasone eye ointment in treating persistent corneal epithelial dysfunction (PED) after cataract surgery. METHODS: 26 cases diagnosed as PED after cataract surgery accept the tobramycin/dexamethasone ophthalmic ointment and intense pulse light treatment in the Xiamen University of Xiamen eye center between September 2016 and April 2022 were retrospectively analyzed, mainly including clinical manifestations, characteristics of morphological changes imaged by in vivo confocal microscopy, meibomian glands infrared photography, lipid layer thickness (LLT), management and therapeutic effects. RESULTS: There were 26 eyes, include 8(35%) males and 15(65%) females with an average age of 69.6 ± 5.2 years(50 to 78 years). The mean hospitalization time was (18.4 ± 7.5) days after cataract surgery. Twenty patients had meibomian gland dysfunction. Infrared photography revealed varying loss in the meibomian glands, with a mean score of 3.8 ± 1.2 for gland loss. The mean LLT was 61.6 ± 8.4 nm. After treatment, 20 patients were cured, and 3 received amniotic membrane transplantation. After treatment, the uncorrected visual acuity (UCVA) and best-corrected vision activity (BCVA) improved (P < 0.001), and there was no significant difference in intraocular pressure (IOP) before and after treatment (P > 0.05). CONCLUSIONS: The early manifestation of PED after surgery is punctate staining of the corneal epithelium. Tobramycin and dexamethasone eye ointment bandages have a good repair effect. The meibomian gland massage combined with intense pulse light treatment can effectively shorten the course of the disease.

Effect of black cloth ointment on hypertrophic scar formation: An investigation using integrated network pharmacology and animal assay.

BACKGROUND: Hypertrophic scars (HS) are a common disfiguring condition in daily clinical encounters which brings a lot of anxieties and concerns to patients, but the treatment options of HS are limited. Black cloth ointment (BCO), as a cosmetic ointment applicable to facial scars, has shown promising therapeutic effects for facial scarring. However, the molecular mechanisms underlying its therapeutic effects remain unclear. MATERIAL AND METHODS: Network pharmacology was first applied to analyze the major active components of BCO and the related signaling pathways. Subsequently, rabbit ear scar model was successfully established to determine the pharmacological effects of BCO and its active component ß-elemene on HS. Finally, the molecular mechanism of BCO and ß-elemene was analyzed by Western blot. RESULTS: Through the network pharmacology, it showed that ß-elemene was the main active ingredient of BCO, and it could significantly improve the pathological structure of HS and reduce collagen deposition. BCO and ß-elemene could increase the expression of ER stress-related markers and promote the increase of apoptotic proteins in the Western blot experiment and induce the apoptosis of myofibroblasts. CONCLUSIONS: Our findings indicate that the material basis for the scar-improving effects of the BCO is ß-elemene, and cellular apoptosis is the key mechanism through which the BCO and ß-elemene exert their effects.

Treatment of hypopigmented burn hypertrophic scars with short-term topical tacrolimus does not lead to repigmentation.

OBJECTIVES: Dyschromia is an understudied aspect of hypertrophic scar (HTS). The use of topical tacrolimus has successfully shown repigmentation in vitiligo patients through promotion of melanogenesis and melanocyte proliferation. It was hypothesized that HTSs treated with topical tacrolimus would have increased repigmentation compared to controls. METHODOLOGY: Full-thickness burns in red Duroc pigs were either treated with excision and meshed split-thickness skin grafting or excision and no grafting, and these wounds formed hypopigmented HTSs (n = 8). Half of the scars had 0.1% tacrolimus ointment applied to the scar twice a day for 21 days, while controls had no treatment. Further, each scar was bisected with half incurring fractional ablative CO2 laser treatment before topical tacrolimus application to induce laser-assisted drug delivery (LADD). Pigmentation was evaluated using a noninvasive probe to measure melanin index (MI) at Days 0 (pretreatment), 7, 14, and 21. At each timepoint, punch biopsies were obtained and fixed in formalin or were incubated in dispase. The formalin-fixed biopsies were used to evaluate melanin levels by H&E staining. The biopsies incubated in dispase were used to obtain epidermal sheets. The ESs were then flash frozen and RNA was isolated from them and used in quantitative reverse transcription polymerase chain reaction for melanogenesis-related genes: Tyrosinase (TYR), TYR-related protein-1 (TYRP1), and dopachrome tautomerase (DCT). Analysis of variance test with Sídák's multiple comparisons test was used to compare groups. RESULTS: Over time, within the grafted HTS and the NS group, there were no significant changes in MI, except for Week 3 in the -Tacro group. (+Tacro HTS= pre = 685.1 ± 42.0, w1 = 741.0 ± 54.16, w2 = 750.8 ± 59.0, w3 = 760.9 ± 49.8) (-Tacro HTS= pre = 700.4 ± 54.3, w1 = 722.3 ± 50.7, w2 = 739.6 ± 53.2, w3 = 722.7 ± 50.5). Over time, within the ungrafted HTS and the NS group, there were no significant changes in MI. (+Tacro HTS= pre = 644.9 ± 6.9, w1 = 661.6 ± 3.3, w2 = 650.3 ± 6.2, w3 = 636.3 ± 7.4) (-Tacro HTS= pre = 696.8 ± 8.0, w1 = 695.8 ± 12.3, w2 = 678.9 ± 14.0, w3 = 731.2 ± 50.3). LADD did not lead to any differential change in pigmentation compared to the non-LADD group. There was no evidence of increased melanogenesis within the tissue punch biopsies at any timepoint. There were no changes in TYR, TYRP1, or DCT gene expression after treatment. CONCLUSION: Hypopigmented HTSs treated with 0.1% tacrolimus ointment with or without LADD did not show significantly increased repigmentation. This study was limited by a shorter treatment interval than what is known to be required in vitiligo patients for repigmentation. The use of noninvasive, topical treatments to promote repigmentation are an appealing strategy to relieve morbidity associated with dyschromic burn scars and requires further investigation.

Efficacy and safety of tirbanibulin 1% ointment in actinic keratoses: Data from two phase-III trials and the real-life clinical practice presented at the European Academy of Dermatology and Venereology Congress 2022.

BACKGROUND: The 31st European Academy of Dermatology and Venereology (EADV) Congress took place between 7th and 10th of September 2022 in Milan, Italy. OBJECTIVES: We report presented clinical data on the efficacy/effectiveness, safety and tolerability of tirbanibulin 1% ointment that has recently been licensed for actinic keratosis (AK) of the face or scalp in adults. METHODS: Summary of presentations given at the EADV Congress. RESULTS: Prof. Pellacani presented two post hoc analyses from two phase-III trials with AK patients (NCT03285477 [N = 351] and NCT03285490 [N = 351]): A descriptive analysis of medical history, concomitant medications, and safety results confirming a favourable profile for tirbanibulin showing that number of baseline AK lesions was not correlated to severity of local skin reactions. The latter analysis showed that cases of tirbanibulin application site pain or pruritus were few, and most were found to be mild. Prof. Kunstfeld reported six real-life clinical cases in Austria showing good tirbanibulin effectiveness, safety and tolerability for the treatment of new or recurring AK lesions. Results demonstrated that after 2- to 4-month follow-up, tirbanibulin was well tolerated and effective in AK patients. Presentations by Dr. Patel confirmed good outcomes and tolerability of tirbanibulin in Olsen grade 1-2 AK (N = 12) and porokeratosis patients (N = 4) treated once daily for 5 consecutive days in the United Kingdom. Furthermore, real-world experience in solid organ transplant recipients (N = 2) demonstrated effectiveness of tirbanibulin in skin field cancerization treatment. A symposium sponsored by Almirall was conducted during the congress in which Dr. Hadshiew and Dr. Lear brought together their clinical experience in Germany and the United Kingdom respectively. Interesting clinical cases of 5 consecutive days of tirbanibulin treatment compared to other treatments were discussed with attendees, as well as current treatment needs of AK patients. CONCLUSIONS: This article provides an overview of presentations and symposium discussions, summarizing key phase-III results and real-life clinical experience with tirbanibulin shared by dermatologists across Europe.

Patient- and Clinician-Reported Outcomes for Tirbanibulin in Actinic Keratosis in Clinical Practice Across the United States (PROAK).

BACKGROUND: The Patient-Reported Outcomes in Actinic Keratosis (PROAK) study evaluated patient- and clinician-reported outcomes (PRO; ClinRO) during 24 weeks of follow-up among adult patients with actinic keratosis (AK) on the face or scalp who were administered tirbanibulin 1% ointment in real-world community practices in the United States.  Methods: Quality of life (QoL) was assessed by Skindex-16 at week (W) 8. Additionally, effectiveness (Investigator Global Assessment [IGA]), PRO and ClinRO (Treatment Satisfaction Questionnaire for Medication and Expert Panel Questionnaire), safety, and tolerability were assessed at W8 and W24. RESULTS: The safety population included 300 patients; the full analysis set included 290 patients (278 patients at W24). At W8, a statistically significant difference (P<0.03) was observed for Skindex-16 domains in all assessed subgroups. Clinicians and patients reported high global satisfaction (mean [SD] scores of 74.9 [23.9] and 72.0 [24.6], respectively) at W24. Overall skin appearance improved from baseline to W24 (83.6% clinicians; 78.5% patients). IGA success (IGA score of 0-1) was achieved by 71.9% of patients at W24 with a similar % at W8 (73.8%) suggesting a stable effectiveness over time. About 5% of patients reported at least one adverse event, 4% reported at least one serious adverse event and no patients reported serious adverse drug reactions. At W8, the most frequently reported local skin reactions were mild/moderate erythema (47.6%) and flaking/scaling (49.6%). CONCLUSIONS: Treatment with tirbanibulin demonstrated effectiveness in the management of AK lesions and a favorable safety and tolerability profile. Furthermore, QoL was improved as early as W8, and both patients and clinicians reported high levels of treatment satisfaction, independently of patients' characteristics.

An Over-the-Counter Healing Ointment: Benefits in Dry Skin and Wound Healing.

BACKGROUND: The use of ointments can be beneficial for dry, chapped, or cracked skin and also for supporting wound healing. We describe the results of 2 studies with an over-the-counter healing ointment (HO) to evaluate the effects on skin hydration and in the setting of wound healing after dermatologic procedures.  Methods: Study 1 was a single-center, in-use study using HO on qualified areas at least once daily for 4 weeks in subjects with dry, cracked body skin and self-perceived sensitive skin. Study 2 was a multi-center study of wound healing in subjects using HO on a daily basis after having dermatologic surgical procedures.  Results: In Study 1, there was a significant reduction in skin dryness after 1 and 4 weeks of HO use (P<0.05). Image analysis of the skin revealed a significant increase in skin smoothness after the first application of HO in 100% of subjects (P<0.05). Tolerability and safety were excellent, and HO was well-perceived by subjects throughout the study. In Study 2, HO improved clinical assessments at all time points compared with baseline with a decrease in erythema, edema, scabbing/crusting, and an improvement in overall wound appearance (P<0.05). There was no worsening or significant increase in measures for tolerability parameters at any study visits. Additionally, HO achieved a favorable perception by study subjects.  Conclusions: HO has a well-established safety profile and has been shown to improve both skin hydration and the overall wound healing process after dermatologic surgical procedures.

The efficacy of a transdermal hydrogel patch containing betamethasone dipropionate for treatment of chronic hand eczema: A single-blind, randomized and controlled trial.

BACKGROUND: Topical corticosteroids under occlusion have been used to enhance the treatment of eczema. However, no study has investigated the efficacy of a steroid-containing transdermal patch for the treatment of chronic hand eczema. METHODS: We conducted a randomized, controlled, assessor-blinded trial to determine the efficacy of a transdermal patch containing betamethasone dipropionate compared to topical betamethasone dipropionate ointment in the treatment of mild to moderate chronic hand eczema. The patients were included and assigned to receive either the transdermal patch once daily at night or the ointment twice daily for a period of 8 weeks. The outcomes were assessed using the Hand Eczema Severity Index (HECSI), Physical Global Assessment (PGA) score, self-reported compliance, level of patient satisfaction, quality of life, and side effects. RESULTS: Fifty-six patients completed this study. At 8 weeks, there was a significant reduction in the HECSI scores in both the transdermal patch and topical ointment groups compared to those measured at baseline (14.61 to 1.86, p < 0.001; 18.46 to 3.43, p < 0.001, respectively) without a statistically significant difference between the two groups. Similarly, the two groups did not show any significant difference in the PGA scores, quality of life and side effects. However, the transdermal patch group reported better compliance and a higher level of patient satisfaction than the topical ointment group. CONCLUSION: The transdermal corticosteroid patch has proven to be a safe and effective treatment, comparable to topical corticosteroids, after 8 weeks of use. Its sustained-release properties, along with once-daily use, can improve patient satisfaction and promote greater adherence to the treatment. TRIAL REGISTRATION: This study was registered with the Thai Clinical Trials Registry (www. CLINICALTRIALS: in.th) under registration number TCTR20220413003.

Cream versus ointment: Randomized single-blinded study on the adherence to treatment with topical methylprednisolone aceponate.

BACKGROUND: Overall adherence in the treatment of chronic dermatoses is poor. Textbooks state an adherence dependence on galenics. TRIAL DESIGN: Prospective, randomized, parallel-grouped, single-blinded (investigator), monocentric clinical trial (phase IV) on the adherence to treatment of chronic mild to moderate hand eczema with topical methylprednisolone aceponate (MPA, Advantan®) in different vehicles. OBJECTIVES AND ENDPOINTS: Primary objective was the assessment of the adherence depending on vehicle type in patients with chronic hand eczema. Secondary objective was improvement after a 4-week treatment period. Primary Endpoint Adherence is defined as the percentage of patients applying at least aimed daily dose. Prescribed daily dose was defined as the planned number of applications per day (1) * surface (measured) * aimed amount per application (mg/cm2 ). Truly applicated daily dose was evaluated as individual mean amount per dose * individual mean number of applications per day. Adherence was assumed, if truly applicated daily dose is at least 75% of the prescribed daily dose and the individual mean number of applications per day is at least 0.85. Secondary Endpoint Efficacy was measured by improvement of Hand Eczema Severity Index (HECSI) and Investigator's Global Assessment (IGA) after a 4-week treatment period and in addition to Quality of Life in Hand Eczema Questionnaire (QOLHEQ) and Visual Analogue Scale (VAS) to assess pruritus. METHODS: Number of participants randomized to each group 40, 80 total. Group 1 MPA-C: Methylprednisolone aceponate 0.1% cream and barrier repair emollient (Bepanthen® Sensiderm). Group 2 MPA-FO: Methylprednisolone aceponate 0.1% fatty ointment and barrier repair emollient (Bepanthen® Sensiderm). Adherence to treatment was compared via Fisher's exact test. RESULTS: Of the patients, 48% were adherent according to our definition. There was no significant difference between MPA-C (42.1%) and MPA-FO (54.1%; p = 0.36; group difference-12.0%, 95% CI-34.3%-11.5%). Generalized-linear-model-analysis of adherence to study treatment with factors emollient use, treatment, time and treatment-time interaction showed a parallel between adherence and amount of emollient use (odds ratio 1.74, p = 0.0038; 95% CI-1.22-2.52). Improvement of hand eczema was seen according to clinical scores without remarkable differences between the groups. CONCLUSIONS: No dependence of adherence on galenics of topical treatment of chronic hand eczema could be proved. Patients who use more emollient tend to be more adherent to the topical treatment.

308 nm excimer laser and tacrolimus ointment in the treatment of facial vitiligo: a systematic review and meta-analysis.

This study aimed to investigate the effects and safety of 308 nm excimer laser (308 nm EL) and tacrolimus ointment (TO) in the treatment of facial vitiligo (FV). We searched Cochrane Library, PUBMED, EMBASE, CNKI, and WANGFANG from inception to June 1, 2023. Outcomes included overall response rate (ORR), total adverse reaction rate (TARR), recurrence rate at 3-month (RR-3) and recurrence rate at 6-month (RR-6). The outcome data were presented as odds ratios (OR) with 95% confidence intervals (CI). The risk of bias was assessed by Cochrane risk-of-bias tool and data analysis was performed by RevMan 5.4 software. This study included a total of 19 trials involving 2085 patients. When comparing 308 nm EL monotherapy with 308 nm EL plus TO, significant differences in the ORR (OR = 4.29, 95% CI [2.97, 6.19], I2 = 0%, P < 0.001), RR-3 (OR = 0.18, 95% CI [0.05, 0.69], I2 = 0%, P = 0.01), and RR-6 (OR = 0.38, 95% CI [0.14, 1.03], I2 = 39%, P = 0.06) were found between the two managements. When comparing TO monotherapy with TO plus 308 nm EL, its results showed significant differences in the ORR (OR = 4.21, 95% CI [2.90, 6.11], I2 = 0%, P < 0.001), TARR (OR = 0.42, 95% CI [0.22, 0.81], I2 = 4%, P = 0.009), and RR-3 (OR = 0.32, 95% CI [0.01, 8.03], P = 0.49) between the two modalities. The results of this study suggest that the combination of 308 nm EL and TO is more effective than either treatment alone for the treatment of FV.

Perianal Ulcers from Antihemorrhoidal Ointment: A Case Report and Literature Review.

ABSTRACT: Perianal ulcers (PAUs) related to antihemorrhoidal product use have been recently reported in the literature through a few case reports. However, other etiologies of PAU must be ruled out, including infectious disease, inflammatory disease, malignancy, pressure injuries, radiotherapy, and other topical drugs. In this report, the authors describe two cases of PAUs due to an antihemorrhoidal ointment. In case 1, a 68-year-old woman with a history of hemorrhoids presented with PAUs after using an antihemorrhoidal ointment for 2 months. The ulcers were assessed through a histopathologic study and treated with calcium alginate dressings, with complete re-epithelialization occurring after 2 months. In case 2, a 58-year-old woman with a history of hemorrhoids developed painful PAUs while using an antihemorrhoidal ointment for 2 months. No other probable cause was found, and the ulcers were treated by discontinuing the ointment. The ulcers showed marked improvement, and complete re-epithelialization occurred after 6 weeks without additional treatment.
