Giant perianal condyloma successfully treated with podophyllin at 25% in solid petrolatum

Purpose: Giant perianal condyloma (GPC) is a rare condition. The effective treatment is a multidisciplinary challenge; topical treatments are usually ineffective, and surgical resection has significant morbidity. Podophyllin at 25% in solid petrolatum (25%PSP) can be an effective treatment option for GPC. The aim of the present study was to assess its response and tolerability. Methods: This retrospective, single-center case series evaluated the clinical response of 14 patients with GPC treated with 25%PSP in a public hospital in Buenos Aires between December 2015 and December 2019. After obtaining a full history and performing a physical exam, the lesions were measured and photographed. Biopsies were performed to exclude malignancy, as well as exams to rule out pregnancy. Podophyllin at 25% in solid petrolatum was administered topically in cases of GPC and washed off by the patients at home after 4 hours. The patients underwent at least 4 weekly visits, which included interval history, photodocumentation of the lesions, and provider-applied 25%PSP. The response rate was assessed by comparingmeasurements and the overall decrease in volume of the GPC based on photos from the first and last sessions. Adverse outcomes were noted. Results: In total, 10 men, 3 women, and 1 transgender woman with GPC unresponsive to prior treatments and a mean age of 34.5 years were included. A total of 12 patients were immunosuppressed. All the perianal lesions were circumferential and measured between 8 cm and 20 cm. Overall, 7 patients had genital condyloma outside of the anus and perianus; the histology showed low-grade squamous intraepithelial lesions in all cases. While on treatment, 7 patients reported dermatitis, and 71% of the patients had 75% reduction in lesion size. Conclusions: Podophyllin at 25% in solid petrolatum is an effective, well-tolerated topical treatment option for GPC. (AU)

Dolor neuropático localizado / Localized neuropathic pain

Resumen El dolor neuropático localizado (DNL) es de origen periférico y se caracteriza por áreas circunscritas de dolor con sensibilidad anormal de la piel o síntomas espontáneos característicos de dolor neuropático, por ejemplo, dolor urente. Se debe resaltar que el DNL está confinado a un área específica no mayor a una hoja de papel tamaño carta. El DNL representa 60 % de las condiciones de dolor neuropático. No existe una única etiología. El abordaje diagnóstico es similar al de otros síndromes dolorosos neuropáticos. Se utilizan herramientas diagnósticas generales para evaluar las características clínicas. En la actualidad no existen guías específicas de manejo del DNL, por lo que se utilizan las guías para dolor neuropático en general. En las guías de la Sociedad Canadiense de Dolor se incluyen los tratamientos tópicos como parte de las estrategias de segunda línea. Pese a la falta de guías, los parches de lidocaína a 5 % y los parches de capsaicina a 8 % han demostrado ser efectivos en modelos de DNL.

Abstract Localized neuropathic pain (LNP) is of peripheral origin and is characterized by circumscribed areas of pain with abnormal skin sensitivity or spontaneous symptoms that are characteristic of neuropathic pain, e.g. burning pain. It should be noted that LNP is confined to a specific area no larger than a letter size sheet of paper. LNP accounts for 60 % of neuropathic pain conditions. There is no single etiology of LNP. The diagnostic approach is similar to that for other neuropathic pain syndromes. General diagnostic tools are used to assess clinical features. So far, there are no specific guidelines for the management of LNP; for this reason, guidelines for general neuropathic pain are used. Topical treatments are included as part of second-line strategies in the Canadian Pain Society guidelines. Despite the lack of guidelines, 5 % lidocaine patches and 8 % capsaicin patches have been proven effective in LNP models.

Bovine digital dermatitis in the Brazilian Amazon biome and topical treatment with Copaifera reticulata oil / Dermatite digital bovina no bioma amazônico brasileiro e tratamento tópico com óleo de Copaifera reticulata

Bovine Digital Dermatitis (BDD) was studied in crossbred dairy cows grazing in Rondon do Pará, in the state of Pará, as well as in Açailândia and Cidelândia, in the state of Maranhão, Brazilian Amazon biome. The digits inspection from the dairy cows during milking was performed in ten farms comprising four visits (August and November 2016; April and July 2017). The cows were kept all year in pastures, and were mechanically milked on concrete floors and the animals were protected against the rains in eight farms, maintaining a daily cleaning, however, it could not be found a concrete floor in pre- or post-milking to ensure milking parlor on three farms. Manual milking on no concrete floors was performed in two farms. No preventive measures against hoof lesions were adopted. The BDD prevalence was 1.3% (22/1664), and no statistical difference among rainy or no rainy season was obtained (p = 0.72). The BDD lesions were classified according to "M system" (M0 = no lesion, M1 = active ulceration <2cm, M2 = active ulceration >2cm, M3 = healing stage, M4 = chronic stage, M4.1 = M4 with active ulceration). Regarding the 22 BDD lesions observed, 22.7% (5/22) were M1 stage, 36.4% (8/22) M2, 22.7% (5/22) M3, 13.6% (3/22) M4 and 4.5 (1/22) M4.1. Hypertrophic hairs at the edges of the lesions caused by fly larvae of genus Cochliomyia spp. as well as alterations on the hoof were also observed. Topical treatment was performed in six BDD lesions with a raw extract from trees of the genus Copaifera reticulata (Copaiba oil) and compared with the treatment of salicylic acid paste in five BDD lesions. The lesions were protected with a bandage for seven days and followed weekly until recovery. The complete therapeutic responses were 83.4% (5/6) and 75% (3/4), respectively, with an average time of seven weeks. The BDD in the Amazon biome occurs in low prevalence, not seasonal, and presents macro and microscopic features similar to BDD lesions from dairy cattle kept in free-stall housing. The treatment with copaiba oil showed similar results to the treatment of salicylic acid paste and can be used in control measures to BDD in the Amazon biome.(AU)

A dermatite digital bovina (DDB) foi estudada em vacas mestiças leiteiras nos municípios de Rondon do Pará no Pará, Açailândia e Cidelândia no Maranhão, bioma amazônico brasileiro. Para tanto, foram realizadas quatro visitas a 10 propriedades, nos meses de agosto e novembro em 2016 e abril e julho em 2017, e realizada a inspeção dos dígitos de 1.664 vacas em lactação durante a ordenha. Nestas propriedades as vacas eram criadas a pasto durante todo o ano e ordenhadas mecanicamente em oito propriedades. As quais, as salas de ordenha tinham piso concretado, com proteção contra as chuvas e era realizada a limpeza diariamente. No entanto, em três dessas propriedades, as salas de pré ou pós ordenha tinham piso não concretado e em duas, a ordenha era manual em piso de chão batido. Em todas elas não havia medidas profiláticas para afecções podais. A prevalência de DDB foi de 1,3% (22/1.664) e não se obteve diferença estatística entre os períodos chuvoso e não chuvoso (P = 0,72). As lesões observadas foram classificadas de acordo com o sistema M (M0-sem lesão; M1-lesão ulcerada <2cm; M2-lesão ulcerada >2cm; M3-lesão em cicatrização; M4-lesão crônica; M4.1- M4 com área ulcerada). De 22 lesões observadas, 22,7% (5/22) apresentavam-se em estágio M1, 36,4% (8/22) em M2, 22,7% (5/22) em M3, 13,6% (3/22) em M4 e 4,5% (1/22) em M4.1. Pelos hipertrofiados nos bordos das lesões, larvas de moscas do gênero Cochliomyia spp. e alterações no tecido córneo também foram observados. Nas lesões de 11 bovinos, em seis, foi realizado o tratamento tópico com extrato bruto de Copaifera reticulata (óleo de copaíba) e em cinco, com a pasta de ácido salicílico a 660mg/g e ambos os tratamentos foram protegidos com bandagem por sete dias. Após, as lesões foram acompanhadas semanalmente até a cura e obteve-se um índice de 83,4% (5/6) e 75% (3/4) de cura com esses tratamentos, respectivamente, com uma média de 7 semanas. Conclui-se que no bioma amazônico a DDB ocorre em baixa prevalência, não sazonal e com características macroscópicas semelhantes às lesões de vacas leiteiras criadas em sistema free stall. O tratamento com o óleo da copaíba apresentou resultados semelhante ao ácido salicílico e pode ser uma alternativa como medida de controle da DDB no bioma amazônico.(AU)

Chitosan-based biocompatible dressing for treatment of recalcitrant lesions of cutaneous leishmaniasis: A pilot clinical study

Background: Chitosan has a biocompatible, biodegradable and nontoxic nature. The effectiveness of nano-chitosan films in the treatment of cutaneous leishmaniasis has been confirmed previously in susceptible laboratory animals. Aims: The aim of this study is to evaluate the safety and efficacy of a chitosan-based biocompatible dressing in patients with cutaneous leishmaniasis who were either nonresponsive to or had medical contraindications for conventional treatments. Materials and Methods: A total of 10 eligible patients were included in this single arm, single center study. The sterile chitosan film was immersed in saline serum and was cautiously extended over the wound to avoid air occlusion. Sterile Vaseline gauze was then applied and the film was kept on the wound site for 7 days and was repeated every week until the healing was completed. Complete clinical response was defined as complete re-epithelialization of the skin lesion as well as microscopic negative results for amastigote forms of Leishmania sp. Results: All patients showed either significant (30%) or complete (70%) improvement after 8 weeks of therapy and at 16 weeks post treatment all cases were completely cured. It was well tolerated and there were no product-related adverse events such as allergic reaction or infection. Moreover, no recurrences were observed in any patients after 6 months follow-up. Limitations: The lack of a control group, relatively small sample size and failure to evaluate the histological and molecular effects of chitosan were the limitations of this study. Conclusion: Our findings confirmed that chitosan can be safely and effectively used for the treatment of cutaneous leishmaniasis. We were unable to find any previous clinical study in evaluating the efficacy of chitosan for cutaneous leishmaniasis on human subjects. Further studies are recommended to design a randomized, double-blinded clinical trial with more volunteers who infected with different species of Leishmania and various clinical forms of cutaneous leishmaniasis.

Comparative clinical study of efficacy and safety of adapalene 0.1% gel versus benzoyl peroxide 2.5% gel for the treatment of acne vulgaris

Background: Acne vulgaris is characterised by comedones, papules, pustules and nodules occurring in a sebaceous distribution. Topical treatments, such as adapalene and benzoyl peroxide, are popular in mild to moderate acne vulgaris. This study was aimed to compare the efficacy and safety of adapalene with benzoyl peroxide in the patients of mild to moderate acne vulgaris.Methods: We planned a randomized, open-labelled, prospective study to compare the efficacy and side effects of adapalene and benzoyl peroxide in acne patients. A total of 100 patients with mild to moderate acne vulgaris were included in the study. They were randomly divided into 2 groups with 50 patients in each group. One group was given 0.1% adapalene gel and the other group received 2.5% benzoyl peroxide gel. Efficacy was assessed as reduction in the lesion counts, whereas for safety, the side effects like dryness, burning, irritation, erythema were recorded during the treatment. Total duration of the study was 3 months.Results: The study revealed that adapalene was more effective than benzoyl peroxide in treating non-inflammatory and inflammatory lesions of acne vulgaris, and there was a statistically significant difference found between the groups (p?0.05) in efficacy. Adapalene was also found to be comparatively safer than benzoyl peroxide because the patients treated with adapalene had lesser side effects than those treated with benzoyl peroxide.Conclusions: Our study concludes a better efficacy and safety of adapalene than benzoyl peroxide in the treatment of mild to moderate acne vulgaris.

Effects of copaiba oil on dermonecrosis induced by Loxosceles intermedia venom

Accidents caused by spiders of the genus Loxosceles constitute an important public health problem in Brazil. The venom of Loxosceles sp induces dermonecrosis at the bite site and systemic disease in severe cases. Traditional medicine based on plant-derived products has been proven to reduce the local effects of envenomation. The present study verified the healing effects of copaiba oil on lesions induced by the venom of L. intermedia. Methods: Cutaneous lesions were induced on the backs of rabbits by intradermal injection of L. intermedia venom. Copaiba oil was applied topically 6 hours after injection; the treatment was repeated for 30 days, after which animal skins were removed and processed for histopathological analysis. Blood samples were also collected before and 24 hours after venom inoculation to measure the hematological parameters. Results: Compared to the control group, the platelet count was reduced significantly in all groups inoculated with venom, accompanied by a decreased number of heterophils in the blood. The minimum necrotic dose (MND) was defined as 2.4 μg/kg. Topical treatment with copaiba oil demonstrated a differentiated healing profile: large skin lesions were observed 10 days after venom inoculation, whereas formation of a thick crust, without scarring was observed 30 days after venom inoculation. Histopathological analysis showed no significant difference after treatment. Nevertheless, the copaiba oil treatment induced a collagen distribution similar to control skin, in marked contrast to the group that received only the spider venom injection. Conclusions: We conclude that copaiba oil may interfere in the healing process and thus propose it as a possible topical treatment for cutaneous lesions induced by L. intermedia venom.(AU)

Single Dose Topical Application of Clotrimazole for the Treatment of Otomycosis: Is This Enough?

BACKGROUND AND OBJECTIVES: To determine the efficacy of filling the external auditory meatus with 1% clotrimazole at a single visit for the treatment of otomycosis. SUBJECTS AND METHODS: This prospective study included 40 patients who were referred to our clinic with complaints of ear itching, pain, and fullness, and were diagnosed with unilateral otomycosis. After cleaning the mycotic hyphae from the external auditory meatus, the ear canal was filled with 1% clotrimazole, using an intravenous catheter and syringe. The patients received follow-up examinations on post-treatment days 7, 15, and 45. RESULTS: The follow-up otomicroscopic examinations revealed that 95% of the ear canals were entirely clean and that all symptoms had resolved. The post-treatment scores of pain, aural fullness and itching were significantly lower than the pre-treatment scores (p < 0.01). CONCLUSIONS: Filling the external auditory meatus with 1% clotrimazole at a single visit is an easy, efficient, and cost-effective treatment for otomycosis. Additionally, high patient compliance makes this treatment superior to long-term topical therapy.

Leishmaniasis cutánea inducida por especies de leishmanial Viannia en ratones BALB/c y eficacia de un tratamiento tópico / Cutaneous leishmaniasis by Leishmania Viannia species in BALB/c mice and efficacy of a topical treatment

Resumen Introducción: La diversidad de las formas clínicas de la leishmaniasis del Nuevo Mundo (desde formas cutáneas localizadas a diseminadas o formas mucosas) causada por especies del subgénero Viannia podría inferir en la eficacia de los tratamientos tópicos. El objetivo del presente trabajo fue determinar las características de la leishmaniasis cutánea producida por infecciones con Leishmania (V.) braziliensis y L.(V.) panamensis en ratones BALB/c y la eficacia de un mismo tratamiento tópico. Materiales y métodos: Después de la infección con cada una de las especies se realizó seguimiento de las lesiones determinando su tamaño (mm ) y características macroscópicas, cada siete días por 150 días. Las características histopatológicas (en lesiones y órganos) fueron determinadas 70, 106 y 150 días post-infección y la eficacia de un tratamiento tópico (cura de lesión y parasitológica) fue determinada después del tratamiento con un gel de miltefosina aplicado una vez al día por 20 días sobre las lesiones. Resultados: Se observó un aumento del tamaño de las lesiones en ambos grupos de ratones, sin embargo, un mayor tamaño de las lesiones e intensidad de la respuesta inflamatoria con menos alteraciones epidérmicas fue encontrada en los ratones infectados con L. (V.) braziliensis. En ningún grupo se encontraron parásitos en órganos (nódulos, bazo e hígado) ni diferencias en la efectividad del tratamiento tópico utilizado. Conclusión: La eficacia del tratamiento tópico utilizado no fue afectada por las diferencias macro y microscópicas encontradas en la leishmaniasis producida por las dos especies de Leishmania evaluadas.

Abstract Introduction: The efficacy of topical treatments could be affected by the diversity of clinical forms (localized or disseminated cutaneous forms, mucosal forms) of New World-leishmaniasis caused by species of Leishmania from the subgenus Viannia. The aim of this study was to determine the cutaneous leishmaniasis features produced after infection with Leishmania (V.) braziliensis and L. (V.) panamensis in BALB/c mice and to determine the efficacy of one topical treatment. Materials and methods: Cutaneous leishmaniasis lesions were followed up after infection determining their lesion-size (mm2) and other macroscopic characteristics every 7 days for 150 days. Histopathological patterns (in lesions and organs) were determined 70, 106 and 150 days post-infection and the efficacy (lesion and parasitological cure) of miltefosine gel applied topical once a day for 20 days was determined. Results: An increase of size-lesions was observed in both groups of mice, however, a higher lesion- size and inflammatory response but lower epidermal changes were observed in L. (V.) braziliensis compared with L. (V.) panamensis infected ones. No parasites were observed in organs (nodules, spleen and liver) and no differences were observed in the effectiveness of the used topical treatment. Conclusion: The efficacy of the topical treatment used was not affected by the macro and microscopic differences produced after infection by the two Leishmania species evaluated.

Research progress of topical treatment of oral chronic graft versus host disease: a review / 中华口腔医学杂志

Oral cavity is one of the main organs involved in chronic graft versus host disease (cGVHD). Oral cGVHD seriously affects the patient's quality of life. Topical use of glucocorticoid and other agents is the primary topical treatment of oral cGVHD, oral photochemical therapy and various new methods have also been applied in patients recently. These important adjuvant therapies are based on the systemic use of drugs such as immunosuppressive agents, and sometimes, may be the only effective treatment for oral cGVHD. This review will focus on the application of topical agent treatment and oral photochemotherapy in oral cGVHD patients.

Topical Treatment of Onychomycosis / 대한의진균학회지

Onychomycosis is one of the most common diseases of the nails caused by dermatophytes, yeasts, and non-dermatophytic molds. Among the onychomycosis, tinea unguium occurred by dermatophytes such as Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum. Treatment options of onychomycosis include oral and topical antifungal agents, surgery or a combination therapy of theses modalities. The complete remission of onychomycosis requires long-term treatment with systemic and topical antifungal agents and recurrences and re-infections are common. In this review, we provide insights on the topical antifungal agents in onychomycosis and introduce new topical antifungal agents.

Actividad in vitro contra Leishmania y permeación en piel humana de liposomas ultradeformables de miltefosina / In vitro activity against Leishmania and human skin permeation of miltefosine ultradeformable liposomes

Introducción: los liposomas ultradeformables de miltefosina (LUD-MIL) constituyen una opción para el tratamiento tópico en leishmaniasis cutánea penetrando los estratos de la piel hasta la dermis, sitio donde habita el parásito. Objetivo: diseñar LUD-MIL y determinar su actividad contra L. (Viannia) panamensis y L. (V.) braziliensis y la permeación en piel humana. Métodos: los LUD-MIL, liposomas convencionales de fosfatidilcolina (LConv) y LUD-MIL-fluorescente (LUD-MIL-Fluo) fueron preparados por el método de rehidratación de película lipídica. Se caracterizaron fisicoquímicamente y se determinaron: la liberación en membrana semisintéticas, la retención en las capas de la piel y la permeación en piel humana. La citotoxicidad en THP-1 fue determinada por el ensayo colorimétrico de MTT y la actividad en promastigotes y amastigotes intracelulares por recuento microscópico. Resultados: el tamaño, índice de polidispersión, potencial Z y concentración de fosfolípidos de los LUD-MIL fue de 100,7 nm, 0,147, -12,0 mV y 53,24 mM respectivamente. El flujo de MIL a través de la membrana fue mayor con LUD-MIL que con MIL-libre. El tratamiento con LUD-MIL indujo menor acumulación de la MIL en el estrato corneo y mayor permeación que el tratamiento con MIL libre. Los LUD-MIL y los LConv-MIL mantuvieron la actividad de la MIL en los parásitos y células. Los LUD-MIL fueron más tóxicos para las células que los LConv y la MIL y más activos en amastigotes intracelulares de L. (V.) braziliensis. Conclusión: los LUD-MIL preparados conservaron la actividad anti-Leishmania de la MIL y permitieron la liberación del compuesto en membranas y piel humana. Ensayos en modelos experimentales de leishmaniasis cutánea para evaluar la actividad de estas formulaciones son urgentes de realizar(AU)

Introduction: miltefosine ultradeformable liposomes (MIL-LUD) are an option for the topical treatment of cutaneous leishmaniasis penetrating the skin layers to the dermis where the parasite inhabits. Objective: to design MIL-LUD and determine their in vitro activity against L. (Viannia) panamensis and L. (V.) braziliensis and to determine human skin permeation. Methods: MIL-LUD, phosphatidylcholine liposomes (MIL-LConv) and fluorescent MIL-LUD (MIL-LUD-Fluo) were prepared by lipid film rehydration method. They were physicochemically characterized to determine drug release in semisynthetic membrane, retention in skin layers and permeation on human skin membranes. Cytotoxicity in THP-1 was determined by the MTT colorimetric test and activity in promastigotes and intracellular amastigotes by microscopic counting. Results: the size, the polydispersion index, the Zeta potential and phospholipid content were 100.7 nm, 0.147, -12.0mV and 53.24mM, respectively for MIL-LUD. MIL flow through the semisynthetic membrane was greater with MIL-LUD than MIL-free treatment. MIL-LUD treatment induced lower MIL accumulation in the stratum corneum and increased permeation than MIL free treatment. The MIL-LUD and MIL-Conv maintained MIL activity in parasites and cells. The MIL-LUD was more toxic to cells than MIL-Conv and more active against intracellular amastigotes of L. (V.) braziliensis. Conclusion: prepared LUD -MIL retained the anti-leishmanial activity of the MIL and allowed the compound release in human skin and membranes. Testing of experimental cutaneous leishmaniasis models to evaluate the activity of these formulations are urgently needed(AU)

Ulcerative Infantile Hemangioma Treated with Topical Timolol / 대한피부과학회지

Therapeutic options for infantile hemangioma are limited. The nonselective beta-adrenergic receptor antagonist propranolol is an effective therapy for infantile hemangiomas. However, systemic propranolol carries a risk of serious side effects, including bradycardia, hypoglycemia, arrhythmias, hypotension and bronchospasm. Recently, treatment of infantile hemangioma with topical timolol (nonselective beta-blocker similar to propranolol) has been reported. We treated successfully the perineal ulcerative hemangioma with topical timolol. We believe that timolol is a safe and effective topical agent and should be strongly considered as one of good therapeutic options for hemagnioma.

Introducción: La obstrucción del lumen de las colleras es un evento infrecuente, pero que anula la efectividad del dispositivo en la ventilación del oído medio. Existen múltiples opciones de tratamiento tópico para esta situación clínica, sin embargo, los reportes en la literatura al respecto presentan resultados contradictorios. Objetivos: Analizar la efectividad de distintos tratamientos tópicos para destapar una collera ocluida con coágulo de sangre. Material y método: Modelo experimental ex vivo, 184 tubos de ventilación obstruidos con coágulo de sangre. Tratamiento tópico, 8 grupos experimentales (agua oxigenada 3 por ciento, ácido acético 5 por ciento, ciprofloxacino 0,3 por ciento, vinagre de mesa, heparina, mezcla de H2O2/acetato 1:1, suero fisiológico 0.9 por ciento) y 2 grupos control (sin tratamiento). Revisión de permeabilidad de lumen de colleras a los 3, 7 y 10 días. Resultados: El agua oxigenada (H2O2) resulta ser el tratamiento más efectivo (88 por ciento y 92 por ciento de efectividad a los 7 y 10 días). Ciprofloxacino, vinagre de mesa, suero fisiológico y heparina son inefectivos, sin diferencias significativas con grupo control. Ciprofloxacino y suero fisiológico sedimentan más, e incluso tapan colleras previamente permeables. Conclusiones: H2O2 es un tratamiento seguro, efectivo y económico para destapar colleras obstruidas con coágulos de sangre.

Nasal irrigation represents a good alternative of adjuvant therapy in rhino sinusitis, to improve our patient's quality of life with a low-cost and safe method.

Mechanical evaluation of the resistance and elastance of post-burn scars after topical treatment with tretinoin

OBJECTIVE: After burn injuries, scarred skin lacks elasticity, especially in hypertrophic scars. Topical treatment with tretinoin can improve the appearance and quality of the skin (i.e., texture, distensibility, color, and hydration). The objective of this prospective study was to examine the effects of treatment with 0.05 percent tretinoin for one year on the biomechanical behavior and histological changes undergone by facial skin with post-burn scarring. Setting: Tertiary, Institutional. METHOD: Fifteen female patients who had suffered partial thickness burns with more than two years of evolution were selected. Skin biopsies were obtained initially and after one year of treatment. The resistance and elastance of these skin biopsies were measured using a mechanical oscillation analysis system. The density of collagen fibers, elastic fibers, and versican were determined using immunohistochemical analysis. RESULTS: Tretinoin treatment significantly lowered skin resistance and elastance, which is a result that indicates higher distensibility of the skin. However, tretinoin treatment did not significantly affect the density of collagen fibers, elastic fibers, or versican. CONCLUSION: Topical tretinoin treatment alters the mechanical behavior of post-burn scarred skin by improving its distensibility and thus leads to improved quality of life for patients.
