RESUMO
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 8-76â 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.

BACKGROUND: Melasma is a common chronic, relapsing pigmentary disorder that causes psychological impact. Chemical peels are a well-known therapeutic modality used for accelerating the treatment of melasma. OBJECTIVE: To review the published evidence on the efficacy and safety of chemical peels in the treatment of melasma. METHODS: A systematic review was done. A meta-analysis could not be done due to the heterogeneity of data. RESULT: The authors conducted a PubMed search and included prospective case series of more than 10 cases and randomized controlled trials (RCTs) that have studied the safety and/or efficacy of chemical peel in melasma. Out of 24 studies, 9 were clinical/comparative trials and 15 were RCTs. The total sample size was 1,075. The duration of the study varied from 8 to 36 weeks. Only 8 studies were split face. All studies used self-assessment, physician global assessment, and Melasma Area and Severity Index (MASI) for quantifying the results. Glycolic acid was found to be the most safe and effective in melasma. CONCLUSION: Chemical peels were found to be safe and effective in the management of melasma.

BACKGROUND: Improving the appearance of lentigines on the hands is a key component to hand rejuvenation. Soft tissue fillers revolumize hands, but do not address pigmentary changes. OBJECTIVE: This study investigated the effiacy of a 15% trichloroacetic acid (TCA) + 3% glycolic acid (GA) combination peel in improvement of appearance of hand lentigines. METHODS: A prospective evaluator-blinded, split-hand study was performed using a 15% TCA + 3% GA peel to treat patients with hand lentigines. Subjects received a total of 3 treatments at 4-week intervals on 1 hand, with the other hand serving as an untreated control. Final photographs were taken 12 weeks after the last treatment. Two blinded board-certified dermatologists graded improvement in hand lentigines using a 5-point scale. RESULTS: Eighteen of 20 patients completed the study (90%). The mean age was 64.4 years (SE 1.6, range 51-71). The mean pain scores were 3.8 (SE 0.4) on a 10-point scale (1 = no pain, 10 = extremely painful). Blinded evaluators correctly identified the after-treatment photographs in 16 patients (88%). Physician and patient-graded mean improvement of lentigines was significant for treated versus control hands ( p < .01). No adverse events were noted. CONCLUSION: A series of three 15% TCA + 3% GA peels are effective and safe in the treatment of hand lentigines.

BACKGROUND: Melasma and post-inflammatory hyperpigmentation (PIH) are common cosmetic dermatologic conditions that predominantly affect patients with skin phototypes III-VI. Comparing treatment coverage for these pigmentary disorders to treatment coverage for acne vulgaris may demonstrate disparities in insurance coverage for diseases that primarily affect patients of color. OBJECTIVE: Describe differences in Medicaid coverage for topical tretinoin for melasma and PIH vs. acne vulgaris in all 50 states and the District of Columbia. METHODS: This is a cross-sectional study of Medicaid insurance plans in all 50 states and the District of Columbia conducted between February 1 and 28, 2023. Data was collected from online publicly available preferred drug lists, prior authorization criteria, and email/telephone inquiries. Information was collected regarding coverage restrictions, including age restrictions, diagnostic restrictions, preferred drug status, and prior authorization requirements. RESULTS: Complete coverage data for all three clinical indications was retrieved from 30 (58.8%) states; partial coverage data for acne vulgaris was retrieved from 16 (31.4%) states; no coverage data was retrieved from 5 (9.8%) states. Of states reporting coverage data, topical tretinoin is covered in 45 (97.8%) states for acne vulgaris and 10 (33.3%) states for melasma and post-inflammatory hyperpigmentation. There was decreased Medicaid coverage of topical tretinoin for acne vulgaris compared to melasma and PIH (P<0.05). Conclusion: There is differential Medicaid coverage for acne vulgaris compared to pigmentary disorders which disproportionately affect patients of color. Greater advocacy is required to ensure equal treatment for conditions that affect racial minority patients. J Drugs Dermatol. 2024;23(6):e151-e153. doi:10.36849/JDD.8069e  .

BACKGROUND: Acanthosis nigricans is a non-inflammatory skin pigmentary disorder characterized by a dark, velvety appearance, primarily observed in the neck and axillary areas. It is commonly associated with obesity, diabetes, and insulin resistance. Although the primary treatment is correcting the underlying disorders, many aesthetic modalities have been established to improve appearance owing to cosmetic concerns. AIMS: We aimed to compare and investigate the effectiveness and side effects of tretinoin 0.05% and glycolic acid 70% in treating acanthosis nigricans lesions of the axillary and neck area. METHODS: This single-blinded, randomized trial recruited patients with neck or axillary involvement. Each patient was randomized to use cream tretinoin 0.05% every other night on one side, while the other side was treated with glycolic acid 70%, which was applied every 2 weeks at the clinic for four consecutive sessions. The study duration was 8 weeks, and patients were evaluated every 2 weeks based on their response to treatment, satisfaction, and side effects. RESULTS: Thirty patients, including 14 with neck lesions and 16 with axillary lesions, were included. Tretinoin was significantly more effective for axillary lesions in terms of treatment response and patient satisfaction (p = 0.02 and p = 0.008, respectively). It was also shown that as the severity of the lesions increased, the response to treatment and patient satisfaction decreased, specifically when treating axillary lesions with glycolic acid (p = 0.02 and p = 0.03, respectively). CONCLUSION: Neither method was significantly effective for neck lesions. However, tretinoin 0.05% was shown to be more efficacious in treating axillary lesions of acanthosis nigricans, despite causing minimal side effects.

Psoriasis is a chronic, immune-mediated, hyperproliferative skin disease. Etiopathogenesis of psoriasis is not well understood. Plexin B2 was found to have effects on CD100-mediated T-cell morphology and expressed in the immune system. It may play a role in the pathogenesis of psoriasis. To assess the tissue level of plexin-B2 and plexin B2 related gene polymorphism which is signal regulatory protein gamma (SIRPγ-rs71212732) in psoriatic patients before and after NB-UVB, acitretin therapy alone or in combination and to detect correlation between level of tissue plexin B2 and disease severity and improvement. This single blinded randomized controlled trial was carried on 50 psoriatic patients and 50 healthy controls. Psoriasis Area and Severity Index score (PASI) was used to evaluate the disease severity. Tissue plexin-b2 level was measured using ELISA and SIRPγ-rs71212732 (T\C) was assessed using TaqMan™ assays and real-time PCR. A significant lower tissue plexin-B2 level was observed in control group (2.9 ± 0.6 pg/g) than cases (25.8 ± 2.8, pg/g) (p < 0.001). Also, a significantly higher tissue plexin-B2 level was observed in sever psoriasis (32.7 ± 3.8 pg/ml) in than moderate psoriasis (13.6 ± 2.1 pg/ml, p = 0.001). Tissue plexin B2 was positively correlated with diseases severity. Significantly higher (TC& TT) genotypes and mutant (C) allele among patients compared to the controls, p < 0.001 for all. Tissue plexin-b2 level was high in psoriasis vulgaris with positive correlation with disease severity and decreased after treatment. This may indicate a role of plexin-b2 in psoriasis vulgaris pathogenesis.

Summary Introduction: The association of osmidrosis and hyperhidrosis often causes emotional and social problems that may impair the patients' quality of life. The purpose of our study was to analyze the therapeutic results of oxybutynin and topical agents in 89 patients with both osmidrosis and hyperhidrosis. Method: We conducted an observational study at two specialized centers of hyperhidrosis between April 2007 and August 2013. Eighty-nine (89) patients with both osmidrosis and hyperhidrosis were treated with oxybutynin and topical agents. Patients were evaluated before treatment and at 3 and 6 weeks after treatment started, by using the Quality of Life Questionnaire and the Sweating Evolution Scale. Results: Before treatment, 98% of the patients presented with poor or very poor quality of life. After six weeks of treatment, 70% stated their quality of life as being slightly better or much better (p<0.001) and nearly 70% of the patients experienced a moderate or great improvement in sweating and malodor. Improvement in osmidrosis was significantly greater when the axillary region was the first most disturbing site of hyperhidrosis. Conclusion: There was a significant improvement in quality of life and a reduction in sweating and malodor after six weeks of treatment with topical agents and oxybutynin in patients with both hyperhidrosis and osmidrosis. Therefore, clinical treatment should be considered before invasive techniques.
Resumo Introdução: A associação entre osmidrose e hiper-hidrose com frequência causa problemas emocionais e sociais que podem deteriorar a qualidade de vida dos pacientes. O objetivo deste estudo foi analisar os resultados terapêuticos do uso de oxibutinina associada a agentes tópicos em 89 pacientes com osmidrose e hiper-hidrose. Método: Nós conduzimos um estudo observacional em dois centros especializados em hiper-hidrose entre abril de 2007 e agosto de 2013. Oitenta e nove (89) pacientes com osmidrose associada a hiper-hidrose foram tratados com oxibutinina e agentes tópicos. Os pacientes foram avaliados antes do tratamento e após 3 e 6 semanas do início do tratamento, por meio do Questionário de Qualidade de Vida e da Escala de Evolução da Sudorese. Resultados: Antes do tratamento, 98% dos pacientes apresentavam qualidade de vida ruim ou muito ruim. Após seis semanas de tratamento, 70% classificou sua qualidade de vida como sendo pouco ou muito melhor (p<0.001) e aproximadamente 70% dos pacientes relataram melhora moderada ou grande de sudorese e odor. Houve melhora significativamente maior da osmidrose quando a região axilar era o sítio em que a hiper-hidrose mais incomodava. Conclusão: Houve melhora significativa da qualidade de vida e uma redução da sudorese e do odor após seis semanas de tratamento com agentes tópicos e oxibutinina em pacientes com hiper-hidrose associada a osmidrose. Dessa maneira, a terapia clínica deve ser considerada antes de técnicas invasivas.

Abstract The tretinoin peel, also known as retinoic acid peel, is a superficial peeling often performed in dermatological clinics in Brazil. The first study on this was published in 2001, by Cuce et al., as a treatment option for melasma. Since then, other studies have reported its applicability with reasonable methodology, although without a consistent scientific background and consensus. Topical tretinoin is used for the treatment of various dermatoses such as acne, melasma, scars, skin aging and non-melanoma skin cancer. The identification of retinoids cellular receptors was reported in 1987, but a direct cause-effect relation has not been established. This article reviews studies evaluating the use of topical tretinoin as agent for superficial chemical peel. Most of them have shown benefits in the treatment of melasma and skin aging. A better quality methodology in the study design, considering indication and intervention is indispensable regarding concentration, vehicle and treatment regimen (interval and number of applications). Additionally, more controlled and randomized studies comparing the treatment with tretinoin cream versus its use as a peeling agent, mainly for melasma and photoaging, are necessary.

BACKGROUND: Peeling is a procedure which aims to accelerate the process of skin exfoliation. OBJECTIVES: Development of formulations containing lactic acid at 85% or glycolic acid at 70% and the evaluation of these formulations on clinical efficacy in reduction of fine wrinkles. METHODS: Preliminary stability tests were carried out and an in vivo study was performed with three groups with 9 representatives each. One was the control group, which used only sunscreen; another one used lactic acid+sunscreen, and the last group used acid glycolic+sunscreen. Clinical efficacy was assessed with a CCD color microscope, through the digitization of images before and after treatment. The applications were carried out by a dermatologist, once a mont h every 30 days, during 3 months. The area with wrinkles was calculated by planimetry point counting, in accordance with Mandarin-de-Lacerda. RESULTS: The formulations were stable in the visual and Ph evaluation. There was no improvement in the control group; for lactic acid, there was significant improvement after the second peeling application on the outer lateral area of the right eye and after the third application on the outer lateral area of the left eye. For the glycolic acid group, there was significant improvement in the outer lateral area of the left eye after the first application, and of the right eye region, after three applications. The formulations used must be kept under refrigeration and should be manipulated every 30 days. CONCLUSIONS: Both peelings were effective in reducing fine wrinkles of the outer lateral eye area after three applications (p≤0.05%). It was observed that peeling efficacy in the external-lateral region of one eye might be different compared with that in skin of the external-lateral region of the other eye, relative to the speed of skin improvement. .
FUNDAMENTOS: Peeling visa a acelerar o processo de esfoliação da pele. OBJETIVOS: Desenvolver formulações contendo ácido láctico a 85% ou ácido glicólico a 70% e avaliar sua eficácia clínica na redução de rugas finas. MÉTODOS: Testes preliminares foram efetuados e estudo in vivo foi realizado em três grupos com nove representantes cada, separados de forma randomizada. Um grupo foi controle, utilizando apenas fotoprotetor; outro utilizou ácido láctico e fotoprotetor; o último usou ácido glicólico e fotoprotetor. Para eficácia clínica, empregou-se microscópio CCD color, digitalizando-se as imagens do pré e do pós-tratamento. As aplicações foram realizadas por médica dermatologista uma vez por mês, a cada 30 dias, durante três meses. A área com traços de ruga foi calculada pela planimetria por contagem de pontos. RESULTADOS: As formulações foram estáveis na avaliação visual e de pH. Não houve melhora no grupo controle; para o grupo do ácido láctico, houve melhora significativa após a segunda aplicação do peeling na região lateral externa do olho direito e após a terceira aplicação na região lateral externa olho esquerdo. Para o grupo do ácido glicólico, houve melhora significativa na região lateral externa olho esquerdo após a primeira aplicação e, depois de três aplicações, na região lateral externa do olho direito. As formulações magistrais empregadas no estudo devem ser mantidas sob refrigeração e manipuladas a cada 30 dias. CONCLUSÕES: Tanto o peeling de ácido láctico quanto o de ácido glicólico foram eficazes na diminuição de rugas finas da região lateral externa dos olhos após ...

Introducción. Actualmente, la resistencia a los antimicrobianos de las cepas bacterianas involucradas en el desarrollo del acné es una realidad y se hace necesario buscar alternativas terapéuticas para su tratamiento. Objetivos. Diseñar fórmulas en gel a base de aceites esenciales y ácido acético, y evaluar su efectividad en pacientes voluntarios afectados por acné. Materiales y métodos. Se trata de un estudio experimental simple enmascarado de tres fórmulas en gel sobre cuatro grupos de siete pacientes. Los tratamientos antibacterianos (aceites esenciales), queratolíticos y mixtos (ácido acético), se aplicaron diariamente por espacio de ocho semanas. Se hicieron controles semanales para evaluar la evolución de los pacientes. Resultados. Todos los grupos reportaron mejoría (desaparición de las lesiones) de la condición del acné, la cual osciló entre 43 y 75 %, con leves efectos secundarios transitorios relacionados con la aplicación de los tratamientos utilizados. Conclusiones. Las fórmulas estudiadas mostraron ser estables química y físicamente durante la aplicación de los tratamientos, lo cual se demostró mediante análisis de cromatografía de gases, en la cual no se evidenció ningún cambio en los perfiles de composición de los aceites esenciales ni en el del ácido acético. Los resultados se catalogaron entre buenos y excelentes, en particular, el del ácido acético, que logró mejorías superiores al 75 %, dada su actividad mixta antiséptica y queratolítica. Los efectos secundarios (ardor y enrojecimiento) desaparecieron a los pocos minutos de realizada la aplicación y no impidieron el cumplimiento de los tratamientos.
Introduction. Currently, the antimicrobial resistance has developed in bacterial strains involved in the development of acne. Therefore, alternatives to antibiotic treatment have become necessary. Objectives. Gel formulations were designed based on essential oils and acetic acid, and their effectiveness was evaluated in patients affected by acne. Materials and methods. Masked simple experimental study of three gel formulations on 28 volunteer patients, separated in four groups of seven patients. Treatments were applied daily for eight weeks and consisted of (1) antibacterial (essential oils), (2) keratolytic medication (3) essential oils mixed with acetic acetic, and (4) kerolytic medication with acetic acid. Weekly checks were conducted to evaluate patient improvement. Results. All groups reported an improvement of the acne condition, which ranged between 43% and 75% clearance of lesions. Evidence of treatment disappeared within minutes, showing little discomfort or side effects after application. Conclusions. The essential oil formulations were chemically and physically stable during application of treatments. This was demonstrated by gas chromatography, where no evidence no change neither the composition profiles of essential oils nor in acetic acid. The results were ranked good to excellent, particularly for the acetic acid mixture, which achieved improvements of 75%. This appeared to be a result of their joint antiseptic and keratolytic activity. Side effects (burning and redness) disappeared within a few minutes of completing the application, therefore, did not interfere with adherence to treatment.

La isotretinoína es un retinoide empleado en el tratamiento del acné. El objetivo de este estudio fue determinar colesterol, triglicéridos, transaminasa glutámico oxalacética, transaminasa glutámico pirúvica y fosfatasa alcalina, pretratamiento, trimestralmente durante el tratamiento y postratamiento en pacientes tratados con isotretinoína oral procedentes de consultas dermatológicas del Estado Carabobo. La edad Promedio de la muestra estudiada fue (19,4 ± 4,7 años), los valores de colesterol mostraron variación estadísticamente significativa para el primer trimestre (P=0,044), Los triglicéridos se incrementaron en el segundo trimestre (P=0,036) para ambos géneros, mientras que para el tercer trimestre solo el género masculino experimentó incremento. Transaminasa glutámico oxalacético en el primer trimestre se incrementó en el género femenino, sin embargo, no fue estadísticamente significativo. En los demás trimetres los valores de las enzimas hepáticas no superaron los valores de referencia. No se evidencian diferencias estadísticamente significativas entre los niveles del pretratamiento y postratamiento. Es recomendable monitorear los lípidos séricos y transaminasas durante el primer trimestre de tratamiento aunque los cambios observados fueron discretos en la mayoría de los pacientes
Isotretinoin is a retinoid used to treat acne. The aim of this sindy was to determine cholesterol, triglyceride, seric glutami oxalacetic transaminase, seric glutami pyruvic transaminase and alkaline phosphatase pretreatment, quarterly during treatment and post-treatment in patients treated with oral isotretinoin dermatological consultations from Carabobo State. The overage age of the sample was (19.4 ± 4.7 years), cholesterol values showed statistically significant variation in the first quarter (P=0.044). Triglycerides increased in the second quarter (P=0.036) for both genders, while for the third quarter only increase in male. Seric glutami oxalacetic transaminase in the first quarter increased in females, but was not statistically significant. In other quarters the liver enzyme values did not exceed reference values. No statistically significant differences are evident between the levels of pretreatment and postreatment. It is advisable to monitor serum lipids and transaminases during the first quarter of treatment although the observed changes were discrete in most patients

Se presenta una revisión de un total de 11 estudios. Dos estudios realizados en México y 9 en diferentes países. Se incluyeron 429 pacientes con diagnóstico de onicomicosis con confirmación clínica y micológica. El tratamiento consistió en dos pasos: 1) Tratamiento inicial con aplicaciones en la uña infectada de bifonazol-urea cada 24 horas bajo vendaje oclusivo hasta el desprendimiento atraumático de la uña; 2) Tratamiento subsecuente del lecho ungueal con bifonazol crema (Solución o gel) 1 vez al día, durante 4 a 6 semanas. El tiempo del desprendimiento atraumático de la uña fue de 4 a 45 días. El porcentaje de curación micológica fue de 81.44 por ciento en los 9 estudios y en los de México de 79.7 por ciento. La combinación de bifonazol al 1 por ciento más urea al 40 por ciento por ser un medicamento antimicótico y queratolítico es una excelente alternativa terapeútica en los siguientes casos: en pacientes que no excedan de cuatro uñas parasitadas, en pacientes que no puedan ser sometidas a largos tratamientos con antimicóticos sistémicos, anicolisis por Candida y onicomicosis infantil
