RESUMEN

BACKGROUND: Post-acne scars are a common sequela of acne, especially prevalent among young people. Delayed treatment not only affects self-perception of beauty but also affects the mental health of patients. OBJECTIVE: This study aims to investigate the clinical efficacy of microneedle fractional radiofrequency (MFR) combined with botulinum toxin A (BoNT/A) in managing post-acne scars. METHODS: This retrospective study involved 63 adult patients with post-acne scars, divided into two groups: group 1 (n = 30) and group 2 (n = 33). Group 1 received treatment with MFR combined with transcutaneous delivery of BoNT/A, whereas group 2 received treatment with MFR alone. The study observed the clinical outcomes in both groups. RESULTS: Based on experimental analysis, the combination of MFR with transcutaneous delivery of BoNT/A demonstrated superior clinical efficacy compared with group 2. There were no significant differences in baseline data or treatment-related pain and adverse reactions between the two groups. However, group 1 exhibited a higher effectiveness rate, lower ECCA score after treatment, higher satisfaction levels, and statistically significant differences compared to group 2. CONCLUSION: MFR combined with transcutaneous delivery of BoNT/A represents an effective and safe alternative for treating acne scars with minimal side effects and complications. SUMMARY STATEMENT: Post-acne scars are a common sequela of acne and combination therapy proves beneficial. Microneedle fractional radiofrequency (MFR) combined with transcutaneous delivery of BoNT/A can be considered an effective and safe alternative for the treatment of acne scars with minimal side effects and complications. It works together through microneedles, radiofrequency, and botulinum toxin. MFR combined with transcutaneous delivery of BoNT/A is based on the direct action of MFR on acne scars and the use of microneedle to create a transient skin microchannel, facilitating BoNT/A penetration into the skin.

RESUMEN

Percutaneous delivery is explored as alternative pathway for addressing the drawbacks associated with the oral administration of otherwise efficacious drugs. Short of breaching the skin by physical means, the preference goes to formulation strategies that augment passive diffusion across the skin. One such strategy lies in the use of skin penetration and permeation enhancers notably of hydroxylated solvents like propylene glycol (PG), ethanol (EtOH), and diethylene glycol monoethyl ether (Transcutol®, TRC). In a previous publication, we focused on the role of Transcutol® as enhancer in neat or diluted systems. Herein, we explore its' role in complex formulation systems, including patches, emulsions, vesicles, solid lipid nanoparticles, and micro or nanoemulsions. This review discusses enhancement mechanisms associated with hydroalcoholic solvents in general and TRC in particular, as manifested in multi-component formulation settings alongside other solvents and enhancers. The principles that govern skin penetration and permeation, notably the importance of drug diffusion due to solubilization and thermodynamic activity in the vehicle (formulation), drug solubilization and partitioning in the stratum corneum (SC), and/or solvent drag across the skin into deeper tissue for systemic absorption are discussed. Emphasized also are the interplay between the drug properties, the skin barrier function and the formulation parameters that are key to successful (trans)dermal delivery.

RESUMEN

Ruxolitinib cream 1.5% was first approved by the US Food and Drug Administration (FDA) in 2011. Opzelura™ cream was introduced by Incyte Dermatology in 2021 for the short-term and non-continuous chronic treatment of mild to moderate atopic dermatitis (AD) in non-immunocompromised patients aged ≥12 years, whose clinical manifestations are not controlled with prescribed topical therapies, such as topical corticosteroids, topical calcineurin inhibitors, or topical phosphodiesterase-4 ( PDE4) inhibitors, or when such therapies are not advisable. Ruxolitinib is a Janus kinase (JAK) inhibitor that addresses inflammation in AD. It selectively inhibits JAK1 and JAK2, blocking JAK and activating signal transducer and activator of transcription (STAT), thereby interrupting the cytokine pathways responsible for cutaneous inflammation. The targeted downstream cytokines include Interleukin- 4 (IL-4), IL-13, IL-31, and cytokine thymic stromal lymphopoietin (TSLP), which play pivotal roles in the itching and inflammation experienced by AD patients. Ruxolitinib cream is directly applied as a thin layer over AD lesions twice daily up to 20% body surface area (BSA) using no more than 60 g per week. It can be used for up to 8 weeks on delicate or thin skin surfaces.

RESUMEN

Two monozygotic twins (Fitzpatrick skin type II 56-year-old women) with significant photoaging and mild to moderate global fine lines based on the modified Griffiths 10-point scale were enrolled in the study. The past medical etymology and laboratory evaluation were unremarkable. Each subject followed a standardized skin care regimen with topical platelet renewosomesTM (human platelet extract [HPE]) daily for a 12-week duration.1-4 In order to evaluate aesthetic outcomes/changes subjectively, three blinded board-certified plastic surgeons (Yael Halaas, K. Kay Durairaj, and Michael Somenek) compared photographs between baseline and 12-week follow-up (Figure 1). This evaluation was completed using the Global Aesthetic Improvement Scale (GAIS) and the modified Griffiths 10-point scale.5,6.

RESUMEN

INTRODUCTION: knee arthroscopy is a common orthopedic procedure associated with postoperative pain, so optimizing pain management is essential for patient recovery and satisfaction. Lidocaine, a local anesthetic with well-established safety profiles, offers a potential alternative to traditional analgesic methods. Research regarding lidocaine patches has been conducted in several types of surgeries (laparoscopy, gynecological surgery, prostatectomy, etc.) showing promising results for some. This study investigates the effectiveness of transdermal lidocaine 5% patches as a novel approach to postoperative analgesia after knee arthroscopy. MATERIAL AND METHODS: a randomized, single-blind, placebo-controlled trial was conducted with participants undergoing knee arthroscopy. Patients were divided into two groups: one receiving transdermal lidocaine 5% patches and the other a placebo, both along traditional postoperative pain management, and using opioid only in cases with moderate-severe pain. Pain scores, opioid consumption, and patient-reported outcomes were assessed at various postoperative intervals. RESULTS: there was a significant reduction in pain scores and opioid consumption in the lidocaine patch group compared to the placebo group. CONCLUSIONS: transdermal lidocaine 5% patches emerge as a promising adjunct to postoperative pain management in knee arthroscopy patients. Their ease of application, minimal side effects, and opioid-sparing effects contribute to a multifaceted analgesic approach. This study underscores the potential of transdermal lidocaine patches in enhancing the overall postoperative experience for knee arthroscopy patients, advocating for their consideration in clinical practice.


INTRODUCCIÓN: la artroscopía de rodilla es un procedimiento ortopédico común asociado con dolor postoperatorio, por lo que optimizar el manejo del dolor es esencial para la recuperación y la satisfacción del paciente. La lidocaína, un anestésico local con perfiles de seguridad bien establecidos, ofrece una alternativa potencial a los métodos analgésicos tradicionales. Se ha llevado a cabo investigación sobre los parches de lidocaína en diversos tipos de cirugías (laparoscopía, cirugía ginecológica, prostatectomía, etcétera), mostrando resultados prometedores en algunos casos. MATERIAL Y MÉTODOS: se realizó un ensayo clínico aleatorizado, ciego simple y controlado con placebo que incluyó participantes sometidos a artroscopía de rodilla. Los pacientes fueron divididos en dos grupos: uno recibió parches transdérmicos de lidocaína al 5% y otro un placebo, ambos junto con el manejo tradicional del dolor postoperatorio y utilizando opioides sólo en casos de dolor moderado a severo. Se evaluaron las puntuaciones de dolor, el consumo de opioides y los resultados informados por los pacientes en varios intervalos postoperatorios. RESULTADOS: se registró una reducción significativa en las puntuaciones de dolor y el consumo de opioides en el grupo de parches de lidocaína en comparación con el grupo de placebo. CONCLUSIONES: los parches transdérmicos de lidocaína al 5% emergen como un complemento prometedor para el manejo del dolor postoperatorio en pacientes sometidos a artroscopía de rodilla. Su facilidad de aplicación, mínimos efectos secundarios y efectos ahorradores de opioides contribuyen a un enfoque analgésico multifacético. Este estudio destaca el potencial de los parches de lidocaína transdérmica para mejorar la experiencia postoperatoria general de los pacientes con artroscopía de rodilla, abogando por su consideración en la práctica clínica.

RESUMEN

Topical corticosteroids are used extensively in dermatology. Class 1 high potency topical steroids (HPTS) can result in unwanted side effects such as skin hypopigmentation, atrophy, and acneiform eruptions. HPTS are only legally available by prescription to ensure appropriate use in the United States (US). The authors have noticed a recent increase in patients presenting with steroid acne after buying HPTS products in beauty supply stores. These products are marketed as fade creams to treat hyperpigmentation and uneven skin tone. We assessed skincare products containing HPTS (clobetasol or betamethasone) in 33 beauty supply stores in Miami, FL; Washington, DC; and Baltimore, MD. Out of 33 beauty supply stores, 14 (42.42%) contained HPTS skincare products, and they were all located in Miami. Out of 15 stores visited in Miami, 14 (93.33%) contained skincare products with clobetasol, and 5 (33.33%) contained skincare products with both clobetasol and betamethasone. Of the stores selling HPTS skincare products, the number of different brands available ranged from 1 to 7, with an average of 4.21 different brands per store. Our study reveals that HPTS are readily available in over-the-counter skincare products in many beauty supply stores. HPTS skincare products were only available in one of three cities suggesting there may be a regional supplier distributing these products. It may also indicate that there is less oversight of retail stores in Miami with HPTS products. More studies are needed to quantify the availability of these products in different locations throughout the US. Further Studies can help identify this problem and raise awareness among consumers of the dangers of HPTS skincare products in beauty supply stores.

RESUMEN

BACKGROUND: Regenerative aesthetics has garnered significant attention. In this toolkit, exosomes are small extracellular vesicles derived from various sources such as platelets. OBJECTIVE: To characterize the cosmetic effect and tolerability of topical human platelet-derived extract (HPE), Intense Serum (Rion Aesthetics, Inc., Rochester, MN), on facial skin rejuvenation after 12 weeks of twice daily use without any confounding aesthetic procedures. MATERIALS AND METHODS: This prospective, single-arm, non-randomized, evaluator-blinded clinical study evaluated subjects at baseline and 12 weeks using participant questionnaires and photo-documentation with Canfield VISIA-CR 3D PRIMOS. The histological evaluation included Masson's Trichrome for collagen and Verhoeff-Van Gieson staining for elastin. Electron microscopy characterized collagen bundle thickness. RESULTS: Fifty-six participants (mean age: 54 years old) were enrolled. Following topical HPE use, 87.3% of subjects reported improvement in facial skin aging including sustained pigment reduction and improvement in luminosity and color evenness at 12 weeks (P≤0.001). Histology revealed a significant increase in collagen fibril thickness at 12 weeks (P≤0.0001). No serious adverse effects. CONCLUSION: This study demonstrates improvement in facial skin health after topical HPE use, supported by collagen and elastin formation in the dermis. The product is well-tolerated, and participants were satisfied with the overall cosmetic outcome. J Drugs Dermatol. 2024;23(9):735-740. doi:10.36849/JDD.8162.

RESUMEN

BACKGROUND: Mild-to-moderate acne vulgaris (AV) is common among adults, and benzoyl peroxide (BPO) has a long history of efficacy in reducing AV lesions. The efficacy of BPO is comparable for concentrations from 2.5% to 10% used as leave-on therapy, but tolerability is usually best at lower concentrations formulated in well-designed vehicles and with newer formulation methods such as micronization. This study assessed the efficacy and safety of a 2.6% BPO cleanser (Complexion Clearing AV Cleanser, CCAC) in mild-to-moderate AV. METHODS: This was a single-center, open-label, 4-week study of subjects aged 18 to 45 years (n=28) with self-perceived sensitive skin and mild-to-moderate AV. CCAC was applied twice daily (morning and evening) on damp skin. Assessments included lesion counts, clinical photography with porphyrin analysis, patient self-assessment questionnaires, collection of adverse events, and standard tolerability ratings. RESULTS: Total lesion counts were significantly reduced by week 1 of CCAC cleanser use (-25.2%, P<0.05). At week 4, AV lesions were numerically reduced but did not reach statistical significance. Additionally, there was a significant reduction of porphyrin counts at week 1 (-19.4% right side face, -28.8% left side, P<0.05 vs baseline). CCAC was well tolerated, with no significant increase in tolerability ratings at any time point compared to baseline, and patients reported good satisfaction. CONCLUSIONS: CCAC was efficacious in reducing AV lesions in as little as one week, and a trend in reduction was shown through week 4. Additionally, this 2.6% BPO cleanser was also shown to be very well tolerated and well-liked by subjects with self-perceived sensitive skin.

RESUMEN

Acne can cause disfiguring sequelae, such as scarring, post-inflammatory erythema (PIE), and post-inflammatory hyperpigmentation (PIH). These post-inflammatory dyschromias pose a significant psychological burden on patients. This burden disproportionately affects skin of color (SOC) patients and can be the most distressing aspect of acne in SOC patients with skin types IV to VI. Multiple non-ablative lasers are used in the treatment of acne-related PIE and PIH. Combination therapies have shown promise in conditions such as rosacea, acne, and post-inflammatory dyschromia. Addressing both the inflammatory and scarring components of acne is key. Given the role of oxidation in the inflammatory cascade, including antioxidants could be an efficacious adjuvant with non-ablative lasers. This is a single-site, randomized, controlled clinical study of 25 subjects with skin types I to VI with facial PIE and/or PIH from acne. The primary objective was to investigate the clinical efficacy of non-ablative laser therapy followed by the topical application of Silymarin/Salicylic Acid/L-Ascorbic Acid/Ferulic Acid (SSAF) or control in the improvement in oily skin patients with facial PIE and PIH due to acne lesions. There was a statistically significant decrease in PIH and intralesional melanin in patients treated with a combination SSAF and non-ablative laser therapy. Improvement of both PIE and PIH was augmented in combination with SSAF and laser-treated patients compared with the laser-only group, with a concomitant increase in collagen density. This was even more strikingly marked in the SOC subjects, potentially providing an energy-based device (EBD)-based therapy in this population. Limitations of this study include small sample size and length of post-treatment follow-up. J Drugs Dermatol. 2024;23(9):769-773. doi:10.36849/JDD.8309.

RESUMEN

Papulopustular eruptions are the most common dermatologic side effect of epidermal growth factor receptor inhibitor (EGFRI) therapy. Topical corticosteroids and oral tetracyclines are frequently used to manage these eruptions, though these treatments are limited by their adverse effects and efficacy. Results from preclinical studies suggest a role for topical aprepitant (HT-001) in the treatment of EGFRI-induced skin toxicities. Herein a case of EGFRI-induced papulopustular eruption with rapid treatment response to topical aprepitant (HT-001) 2% cream is described and the literature reviewed.

RESUMEN

Lipids play an essential role in skin barrier health. With age, there is a natural reduction of physiological lipids such as fatty acids, ceramides, and cholesterol. The triple lipid restore cream is a moisturizer that contains an optimized lipid ratio for aging skin. The cream contains a 2:4:2 ratio of ceramides, cholesterol, and fatty acids that have been shown to best support aging skin. The triple lipid restore cream has been used in combination with energy-based procedures, to provide patients with comprehensive integrated skincare regimens. With limited clinical data and guidelines available in regenerative medicine, real-world cases serve as an invaluable guide for patients and dermatologists in navigating rejuvenation treatment plans.

RESUMEN

BACKGROUND: The treatment of rosacea is complicated as there are multiple pathogenic factors in play resulting in a myriad of clinical signs and symptoms including facial redness. OBJECTIVE: The primary objective was to evaluate the efficacy and tolerability of a non-prescription anti-redness regimen in patients with rosacea. METHODS: Thirty subjects with rosacea-induced facial erythema were enrolled in this single site, monadic study. The test regimen consisted of a treatment serum, redness-reducing moisturizer, and sunscreen. The test products are formulated with ingredients curated to address the multifactorial pathogenesis of facial redness. Investigator and subject self-assessment for efficacy and tolerability were performed at baseline, weeks 4 and 8. Non-invasive assessments for facial redness and skin hydration were conducted at all time points. RESULTS: Investigator grading showed significant improvement in facial redness of 21% at week 4 and 32% at week 8. Skin's appearance improved as early as 4 weeks while at 8 weeks there was statistically significant improvement in fine lines 15%, radiance/brightness 37%, tactile roughness 44%, visual roughness 41%, and 26% in overall appearance. Non-invasive assessments showed statistically significant improvement in skin hydration of 28% at week 4 and facial redness of 21% by week 8. No tolerability issues were identified by the investigator. CONCLUSION: Patients with rosacea often turn to over-the-counter products to reduce facial redness and improve skin's appearance. In this study, a cosmetic skincare regimen designed to reduce facial redness demonstrated efficacy and tolerability in subjects with rosacea.

RESUMEN

To observe the efficacy of topical antipruritic spray (TAS) in the treatment of epidermal growth factor receptor (EGFR) tyrosine kinase-related rashes, and to evaluate its efficacy and safety. 120 malignant tumor patients with confirmed pathological diagnosis and rash after EGFR application were selected and randomly divided into an experimental group of 60 cases and a control group of 60 cases. The 2 groups were intervened with self-made antipruritic spray and erythromycin ointment for 14 consecutive days. To observe the changes in rash, itching degree, and quality of life index of skin diseases in both groups of patients before and after treatment. The decrease in the number of itching cases in the experimental group reached 53.84%, and after 7 weeks of intervention, the total effective rate of rash treatment in this group of patients (91.67%) was significantly better than that in the control group (36.67%); The symptoms of the dermatology life quality index (DLQI) scale in the experimental group patient table after intervention showed significant changes compared to before intervention. After statistical testing, there was a significant difference between the groups and outside the group (R < 0.05). And the comprehensive effect of the experimental patients with external spray after 14 weeks of intervention reached 93.16%. The self-made antipruritic spray has significant effect on improving EGFR rash and itching, and there is no obvious adverse reaction.

RESUMEN

This study evaluates the use of poly(vinyl alcohol), collagen, and chitosan blends for developing a microneedle patch for the delivery of meloxicam (MEL). Results confirm successful MEL encapsulation, structural integrity, and chemical stability even after ethylene oxide sterilization. Mechanical testing indicates the patch has the required properties for effective skin penetration and drug delivery, as demonstrated by load-displacement curves showing successful penetration of pig ear surfaces at 3N of normal load. In vitro imaging confirms the microneedle patch penetrates the pig's ear cadaver skin effectively and uniformly, with histological evaluation revealing the sustained presence and gradual degradation of microneedles within the skin. Additionally, in vitro drug diffusion experiments utilizing ballistic gel suggest that microneedles commence dissolution almost immediately upon insertion into the gel, steadily releasing the drug over 24 h. Furthermore, the microneedle patch demonstrates ideal drug release capabilities, achieving nearly 100% release of meloxicam content from a single patch within 18 h. Finally, in vivo studies using pigs demonstrate the successful dissolution and transdermal drug delivery efficacy of biodegradable microneedle patches delivering meloxicam in a porcine model, with over 70% of microneedles undergoing dissolution after 3 days. While low detectable meloxicam concentrations were observed in the bloodstream, high levels were detected in the ear tissue, confirming the release and diffusion of the drug from microneedles. This work highlights the potential of microneedle patches for controlled drug release in veterinary applications.

RESUMEN

Lebrikizumab has previously demonstrated efficacy in Phase 3 trials: ADvocate1 and ADvocate2 (as monotherapy), ADhere, and ADhere-J (in combination with topical corticosteroids). Here, the impact of lebrikizumab combined with low- to mid-potency topical corticosteroids on patient-reported outcomes at 16 weeks in Japanese patients with moderate-to-severe atopic dermatitis is evaluated. Eligible patients (n = 286) were randomized 2:2:3 to receive placebo+ topical corticosteroids, 250 mg lebrikizumab every 4 weeks (LEBQ4W+topical corticosteroids, 500 mg loading dose at baseline), or 250 mg lebrikizumab every 2 weeks (LEBQ2W+ topical corticosteroids, 500 mg loading dose at baseline and Week 2) by subcutaneous injection. All PRO endpoints for the study were met; patients in the lebrikizumab in combination with topical corticosteroids groups demonstrated statistically significant and clinically meaningful improvements compared with placebo in combination with topical corticosteroids in Skin Pain NRS, DLQI, POEM, WPAI-AD, and SCORAD scales. Lebrikizumab combined with topical corticosteroids compared with placebo+topical corticosteroids improved patient-reported outcomes in Japanese patients with moderate-to-severe atopic dermatitis.

RESUMEN

Psossibility and appropriate timing of discontinuation of dupilumab for atopic dermatitis (AD) remain unclear. We explored the possibility of patients, who could maintain remission with topical therapy alone after withdrawing dupilumab in the real world. Furthermore, we identified their characteristics. All adult AD patients who initiated dupilumab from June 2018 to July 2022 and were treated with dupilumab for more than 3 months at our hospital were included in this study. The observation period was from June 2018 to July 2023. In 138 patients, 58 (42.0%) discontinued dupilumab at least once. Among them, 18 (13.0%) discontinued dupilumab but reinitiated dupilumab later due to exacerbation. Only seven patients (5.1%) could maintain remission with topical therapy alone after discontinuation of dupilumab, with characteristics of lower POEM, VAS of pruritus, serum levels of TARC and LDH, and neutrophil counts at baseline, and those of longer duration of dupilumab until its discontinuation (24.0 ± 13.3 vs. 12.8 ± 7.3 months) and lower EASI and affected BSA at the discontinuation of dupilumab. In 118 patients treated with dupilumab for at least 1 year, 38 patients (32.2%) discontinued at least once. Only four patients (3.4%) could maintain remission with topical therapy alone after discontinuation of dupilumab, with characteristics of lower POEM at baseline and lower EASI at the discontinuation of dupilumab. In conclusion, maintaining remission after withdrawing dupilumab is challenging. Discontinuation of dupilumab may be considered in patients with low baseline POEM, after more than 2 years of dupilumab treatment, with a substantial decrease in EASI.

RESUMEN

Compared with oral or injection administration, percutaneous immunotherapy presents a promising treatment modality for food allergies, providing low invasiveness and safety. This study investigated the efficacy of percutaneous immunotherapy using hen egg lysozyme (HEL)-loaded PLGA-PEG-PLGA nanoparticles (NPs), as an antigen model protein derived from egg white, compared with that of HEL-loaded chitosan hydroxypropyltrimonium chloride (CS)-modified PLGA NPs used in previous research. The intradermal retention of HEL in excised mouse skin was measured using Franz cells, which revealed a 2.1-fold higher retention with PLGA-PEG-PLGA NPs than that with CS-modified PLGA NPs. Observation of skin penetration pathways using fluorescein-4-isothiocyanate (FITC)-labeled HEL demonstrated successful delivery of HEL deep into the hair follicles with PLGA-PEG-PLGA NPs. These findings suggest that after NPs delivery into the skin, PEG prevents protein adhesion and NPs aggregation, facilitating stable delivery deep into the skin. Subsequently, in vivo percutaneous administration experiments in mice, with concurrent iontophoresis, demonstrated a significant increase in serum IgG1 antibody production with PLGA-PEG-PLGA NPs compared with that with CS-PLGA NPs after eight weeks of administration. Furthermore, serum IgE production in each NP administration group significantly decreased compared with that by subcutaneous administration of HEL solution. These results suggest that the combination of PLGA-PEG-PLGA NPs and iontophoresis is an effective percutaneous immunotherapy for food allergies.

RESUMEN

Atopic dermatitis (AD) is a chronic inflammatory skin disorder that requires a complex management strategy, which often involves multiple and diverse topicals and systemic treatment regimens. While topical steroids and more recently calcineurin inhibitors have been the mainstay therapy for mild-to-moderate disease, recent advances in the understanding of AD pathogenesis have led to the development of different new targets, rapidly widening our therapeutic armamentarium. This review summarizes their efficacy and safety data. We also review topical optimization strategies, including the recently published topical volume calculator, to maximize long-term disease control, especially when using multiple agents at the same time.

RESUMEN

Atopic dermatitis (AD) is a chronic inflammatory skin condition that can be difficult to treat due to a complex etiology and diverse clinical presentations. Itch is the most common symptom associated with AD with profound negative impact on quality of life. Thus, the adjunctive management of itch in patients with AD is needed to control and reduce disease burden. Supplemental treatment options are continuously emerging and undergoing testing in clinical trials. This article summarizes the latest data on topical and systemic adjunctive therapies for AD safety and efficacy in reducing itch.
