Eficácia do propionato de clobetasol 0, 05 nas lesões ulceradas da cavidade bucal / Efficacy of 0.05% clobetasol propionate in ulcerated lesions of the oral cavity

O uso tópico de Propionato de Clobetasol 0,05% em solução aquosa para lesões ulceradas na cavidade bucal é pouco divulgado nacionalmente e tem sido pouco citado em traba-lhos científicos a respeito de sua eficácia, tempo de regressão da lesão e efeitos adversos. Portanto, o objetivo deste estudo foi avaliar retrospectivamente prontuários de pacientes que foram tratados de lesões ulceradas através do uso do Propionato de Clobetasol 0,05%, no ambulatório de estomatopatologia de uma Instituição, a fim de investigar sua eficácia. Foram selecionados prontuários de pacientes que apresentaram a alteração fundamental ulcerada ou erosiva e que fizeram o uso tópico de Propionato de Clobetasol 0,05%. A aná-lise retrospectiva foi feita por um examinador, que fez a seleção da amostra seguindo os critérios de inclusão e exclusão. Foram coletadas as informações: Idade, gênero, diagnós-tico da alteração; quantidade de lesão, tempo de uso, evolução da lesão, tempo exato de regressão e presença de reações adversas. Foram incluídos 17 prontuários, dos quais cinco eram de pacientes com lesões erosivas de líquen plano, três úlceras traumáticas, três lesões liquenóides, dois eritemas multiformes, uma alergia a lactose, uma afta e uma gengivite descamativa. Todos os casos apresentaram resolução da sintomatologia, porém as altera-ções clínicas permaneceram em seis casos, embora mais leves e assintomáticas. Não foi ob-servada nenhuma reação adversa registrada no prontuário. A análise estatística não apontou associação em relação ao sexo (teste Exato de Fisher; p=0,49; p>0,05). Não foi observada diferença estatística significativa na frequência das lesões (teste exato de Fisher; p= 0,85; p>0,05). O uso do Propionato de Clobetasol 0,05% prescrito por até cinco dias se mostrou eficaz no tratamento de lesões ulceradas da mucosa bucal, principalmente para o alívio sintomático, além disso, não revelou efeitos adversos.

The treatment of ulcerated lesions of the oral cavity is usually carried out using topical analgesic drugs, anti-inflammatory corticosteroids, and alcohol-free oral antiseptics. The topical use of 0.05% Clobetasol Propionate in aqueous solution for ulcerated lesions in the oral cavity is little publicized nationally and little mentioned in scientific studies regarding its effectiveness, lesion regression time, and adverse effects. Therefore, the objective of this study was to retrospectively evaluate the medical records of patients who were treated for ulcerated or erosive lesions, using Clobetasol Propionate 0.05%, in the stomatology clinic of an institution to investigate its effectiveness. Medical records of patients who presented the fundamental ulcerated alteration and made topical use of 0.05% Clobetasol Propionate were selected. An examiner selected the sample following the inclusion and exclusion cri-teria and performed the retrospective analysis. The types of information collected were age, gender, diagnosis of the disorder, amount of injury, time of use, the evolution of the injury, exact time of regression, and presence of adverse reactions. A total of 17 medical records were included, of which five were from patients with erosive lichen planus lesions, three traumatic ulcers, three lichenoid lesions, two multiform erythema, one lactose allergy, one cold sore, and one scaly gingivitis. All cases had their symptoms solved, but, in six cases, the clinical changes remained, although milder and asymptomatic. No adverse reaction was noted in the medical record. The statistical analysis showed no association in relation to gender (Fisher's exact test; p = 0.49; p> 0.05). There was no statistically significant diffe-rence in the frequency of injuries (Fisher's exact test; p = 0.85; p> 0.05). The use of 0.05% Clobetasol Propionate, prescribed for up to five days, proved effective in treating ulcerated lesions of the oral mucosa, mainly for symptomatic relief. Furthermore, it revealed no ad-verse effects.

Vulvitis de Zoon: caso clínico / Zoon vulvitis: clinical case

Se presenta un caso de una paciente de 84 años con vulvitis de Zoon. Se trata de una dermatosis vulvar de etiología incierta, muy poco frecuente, que ocasiona sintomatología inespecífica de prurito y escozor vulvar de larga evolución, acompañados de una o varias lesiones focales circunscritas y eritematosas de difícil diagnóstico clínico. Se insiste en la necesidad de realización de biopsia vulvar para obtención de un diagnóstico histológico de certeza. Se comentan las opciones terapéuticas actuales descritas en la literatura aunque no existe un tratamiento de elección.

An 84 year old female patient with Zoons vulvitis case is reported. It is a rare vulvar dermatosis of unknown etiology, with unspecific symptoms such as pruritus and vulvar stinging, both developed over a long period of time, accompanied with focal erythematous injuries. As a clinical diagnosis remains difficult, it is essential that a biopsy is obtained for accurate histological diagnosis. Despite different therapeutic options available, there is no consensus on a standardized treatment.

Comparative histological study on wound healing on rat's skin treated with Mitomycin C or Clobetasol propionate

PURPOSE:To compare histologically the action of Mitomycin C and that of Clobetasol propionate for surgical wound healing in rats.METHODS:A circular skin fragment was surgically removed from 57 Wistar rats. Twenty-two animals were treated with Mitomycin C with topical medication in a single dose, 22 with Clobetasol propionate with a cream medication once a day for 15 days and 13 did not receive any medication. The animals were euthanized 30 and 60 days, and the scars subjected to histological examination.RESULTS: The histological analysis on the samples did not show statistically significant differences regarding the quantities of fibroblasts, fibrocytes and vascular proliferation in the three groups, in the evaluations after 30 and 60 days. In the treated groups with Mitomycin C and Clobetasol there was a decrease in collagen concentration over the 30-day period and an increase in collagen concentration over the 60-day period, in comparison with the control group.CONCLUSIONS: The actions of Mitomycin C and Clobetasol were equivalent and not interfere in fibroplasias and in angiogenesis. Both drugs initially cause a decrease in collagen over a 30-day period and an increase over a 60-day period, demonstrating a delay in the wound healing.

Linear psoriasis: case report on three year old child

Atypical and unusual locations of psoriasis are very frequent. However, localized linear psoriasis is rare, with few cases described in the literature. It is characterized by a linear distribution of psoriasis lesions along Blaschko lines. We report the case of a three years old child, who presented unilateral erythematous scaly plaques arranged along Blaschko lines in the left hemithorax, with no associated symptoms and no lesions in other parts of the body. The differentiation of linear psoriasis from other linear dermatoses is not easy. The combination of a thorough history, a careful examination of the skin and histopathology are essential to ensure the correct diagnosis and appropriate treatment.

Alopecia areata incógnita: casos clínicos y revisión de la literatura / Alopecia areata incognita: clinical cases and literature review

La alopecia areata incógnita es un tipo de alopecia no cicatricial, que ha sido considerada por algunos autores como parte del espectro de alopecia areata. Se presenta como caída difusa de cabello, con visualización variable de vellos cortos, puntos amarillos, puntos negros y pelos en signos de exclamación a la dermatoscopía, y hallazgos histológicos que, si bien varían de acuerdo al tiempo de evolución, son similares a lo encontrado en biopsias de pacientes con patrones clásicos de alopecia areata. Desde que Rebora et al. describe por primera vez su hipótesis de alopecia areata incógnita, se han publicado diversos estudios dirigidos a establecer criterios que permitan definir esta entidad. Sin embargo, aún no se ha llegado a consenso. A continuación, se describen los hallazgos clínicos, dermatoscópicos e histopatológicos de pacientes con alopecia difusa de difícil manejo vistos en el Departamento de Dermatología de la Pontificia Universidad Católica de Chile

Alopecia areata incognita, a type of non-scarring alopecia, has been considered by some authors as a subtype of alopecia areata. Clinically it is characterized by diffuse hair fall, with variable display of short hairs, yellow dots, black dots and exclamation mark hairs on dermoscopy. Its histological findings are similar to those found in biopsies of patients with classical pattern of alopecia areata, although substancial changes may be seen according to the evolution of the disease. Since Rebora et al. described his hypothesis of alopecia areata incognita, several studies have been published to establish a criteria in order to define this entity. However, still no consensus has been reached. In this review, we describe the clinical, dermoscopic and histopathologic features of patients seen at the Dermatology Department of the Pontificia Universidad Católica de Chile with the diagnosis of diffuse alopecia with difficult management.

Penfigoide gestacional "Herpes gestationis": revisión a partir de un caso clínico / Gestational pemphigoid "Herpes gestationis": review from a clinical case

O líquen escleroso e atrófico é uma doença crônica da pele e mucosas, que, usualmente, afeta a área genital de mulheres. Poucos casos de líquen escleroso e atrófico, confinados nos pés e/ou mãos, têm sido relatados. Relatamos um caso de líquen escleroso e atrófico envolvendo as extremidades e,posteriormente, a área perigenital.

Lichen sclerosus et atrophicus is a chronic disorder of the skin and mucosal surfaces, most commonly affecting the female genitalia. Few cases of lichen sclerosus et atrophicus confined to the feet and/or hands have been reported. We report a case of lichen sclerosus et atrophicus involving first the extremities and then the perigenital area.

Oral lichen planus: two case reports in male patients / Líquen plano oral: relato de dois casos em pacientes masculinos

Purpose: Lichen planus is a chronic systemic disease that commonly involves the mucosa of the oral cavity, most often in the absence of skin lesions. Although relatively frequent, oral lichen planus is the target of much controversy, mainly in relation to its pathogenesis and possible potential for malignancy. Thus, the objective of this paper is to report two cases of lichen planus in male patients and to discuss the main aspects of this disease in relation to etiopathogenesis and treatment. Case description: Physical and histopathological examinations were carried out to confirm the diagnosis of oral lichen planus. An elixir of dexamethasone was prescribed in the first case, and in the second case, topical 0.05% clobetasol propionate was prescribed. After fifteen days, both patients presented regression of the lesion. Conclusion: Although the occurrence of oral lichen planus is common, an accurate diagnosis is necessary so that the correct treatment can be established.

Objetivo: O líquen plano é uma doença crônica sistêmica comum que envolve a mucosa oral, na maioria das vezes na ausência de lesões em pele. Embora relativamente comum, o líquen plano oral é alvo de muita controvérsia, especialmente em relação à sua patogênese e possibilidade de uma eventual transformação maligna. Assim, o objetivo deste trabalho é relatar dois casos de líquen plano em pacientes do sexo masculino e discutir os principais aspectos dessa lesão em relação a etiopatogênese e tratamento. Descrição do caso: Exames físicos e histopatológicos foram realizados para confirmar o diagnóstico de líquen plano oral. Foi prescrito elixir de dexametasona no primeiro caso e no segundo caso, foi prescrito o uso tópico de propionato de clobetasol 0,05%. Após quinze dias, os pacientes retornaram com regressão da lesão. Conclusão: Embora a ocorrência de líquen plano oral é comum, o diagnóstico preciso é necessário para que o correto tratamento possa ser realizado.

Double-blind, crossover, placebo-controlled clinical trial with clobetasol propionate in desquamative gingivitis

The aim of this study was to evaluate the efficacy of a 0.05 percent clobetasol propionate ointment administered in trays to 22 patients with desquamative gingivitis in a double-blind, crossover, placebo-controlled trial. Patients received container number 1 and were instructed to apply the ointment 3 times a day for 2 weeks, and to reduce the application to once a day in the third week. Next, the patients were then instructed to discontinue the treatment for 2 weeks, and were then given container 2, used in the same way and for the same length of time as container 1. Regarding signs, 17 patients presented some improvement, while 5 experienced worsening with clobetasol propionate. With the placebo, 14 patients presented some improvement, and 8 patients presented worsening. For symptoms, there was complete improvement in 2 patients, partial improvement in 12, no response in 7, and worsening in 1 with clobetasol propionate. With the placebo, there was partial improvement in 8 patients, no response in 12 and worsening in 2. No statistically significant difference was found between clobetasol and placebo (p>0.05). Within the period designed to treat the gingival lesions of the patients, clobetasol propionate did not significantly outperform the placebo.

O objetivo deste estudo foi avaliar a eficácia do propionato de clobetasol a 0,05 por cento administrada com moldeiras em 22 pacientes com gengivite descamativa por meio de estudo duplo-cego, cruzado, placebo-controlado. Pacientes receberam bisnaga número 1 e foram instruídos a aplicar a pomada 3 vezes ao dia por um período de 2 semanas, e reduzir a aplicação para 1 vez ao dia na terceira semana. Os pacientes foram instruídos a suspender o tratamento por 2 semanas, e então receberam a bisnaga 2, usando-a da mesma maneira que o container 1. Com relação aos sinais, 17 pacientes apresentaram alguma melhora, enquanto 5 apresentaram piora com o propionato de clobetasol. Com o uso do placebo, 14 pacientes apresentaram alguma melhora, e 8 pacientes apresentaram piora do seu quadro clínico. Com relação aos sintomas, houve completa melhora em 2 pacientes, melhora parcial em 12, ausência de resposta em 7, e piora em 1 pacientes durante o uso do propionato de clobetasol. Com o uso do placebo, houve melhora parcial em 8 pacientes, ausência de resposta em 12 e piora dos sintomas em 2 pacientes. Não foi verificada diferença estatisticamente significante em nenhum dos parâmetros entre o uso do clobetasol e placebo; p>0,05. Baseado no protocolo utilizado neste grupo de pacientes, o propionato de clobetasol não demonstrou efetividade significante quando comparado ao placebo.
