Efficacy of a repair cream based on Rhealba Oat plantlets extract and active healing compounds in peelings: benefit to patient's downtime and pain.

BACKGROUND: The frequency of dermatological procedures is steadily increasing, accompanying a growing demand from patients. Chemical peels are a method of resurfacing in the treatment of various skin conditions. However, during the early healing process, patients may impose downtime on themselves. The erythema, pain and poor aesthetic appearance of the skin can lead to unwillingness to participate in social or professional activities. OBJECTIVES: The objective of this study was to evaluate the tolerance and efficacy of a repair cream based on Rhealba Oat plantlets extract and active healing compounds after a peeling procedure. METHODS: Men and women, aged 18-65 years, with Fitzpatrick phototype I-IV, who had previously received a medium-depth chemical peel on the face (TCA 30%) entered with their consent a clinical study evaluating the new test product based on Rhealba Oat and active healing compounds. At the beginning of the study, the selected patients received a TCA 30% medium-depth peel. Afterwards, they were treated during 29 days with the repair cream and evaluated for the benefits to downtime and pain. RESULTS: Significant reductions of pain (P < 0.0114) and erythema (P < 0.0001) were observed in the study. The downtime reduction with the tested cream was 92% - from 9 days after the previous peeling procedure to 0.74 days with application of the tested cream - a difference of 8.39 days. CONCLUSION: In consequence, the tested repair cream based on Rhealba Oat plantlets extract and active healing compounds brings clinical benefit to patients who undergo peeling procedures. By reducing pain and downtime, it allows patients to get back to their daily life activities a week earlier than with previous peels.

Correlation Between Incisional Biopsy Histological Subtype and a Mohs Surgery Specimen for Nonmelanoma Skin Cancer / Correlación entre el subtipo histológico de la biopsia incisional y una muestra de cirugía de Mohs en el cáncer de piel no melanoma

BACKGROUND: Histological diagnosis of a clinically suspected nonmelanoma skin cancer (NMSC) is recommended before treatment. For NMSC, concordance between the histological subtype of the preoperative biopsy and the excision specimen of basal cell carcinoma (BCC) has been reported to range from 10% to 81%. No large study on the concordance between NMSC histology seen in a preoperative biopsy with the following tumour specimen from Mohs micrographic surgery (MMS) has been performed in a Latin American population. OBJECTIVE: The aim of this study was to analyse and compare the histological subtype of the incisional biopsies reviewed by the dermatopathologist with the histological subtype of the tumour specimen obtained during MMS interpreted by the dermatopathologist and the Mohs surgeon. METHODS: A retrospective analysis of 320 NMSC was performed. The interobserver correlation was based on kappa values. RESULTS: The mean weighted kappa value between the preoperative NMSC biopsy and intraoperative histological subtype of the tumour specimen from MMS analysed by the Mohs surgeon and the dermatopathologist was 0.22 and 0.24, respectively. The correlation in the histologic subtype of the intraoperative tumour specimen from MMS that was interpreted by the dermatopathologist and Mohs surgeon was 0.58. CONCLUSIONS: Dermatologists need to be aware of the limited value of incisional biopsies to accurately diagnose the histological subtype of a NMSC. The concordance rate in the histological diagnosis of the tumour specimens that were obtained from MMS between the Mohs surgeon and the dermatopathologist is moderate. However, the correlation is low compared with incisional biopsy subtypes

ANTECEDENTES: Se recomienda diagnosticar histológicamente el cáncer cutáneo no melanoma clínicamente sospechado (CCNM) antes de iniciar el tratamiento. Para el CCNM, se ha reportado una concordancia entre el subtipo histológico de la biopsia preoperatoria y la muestra extirpada del carcinoma de células basales (CCB), que oscila entre el 10 y el 81%. No se han llevado a cabo grandes estudios sobre la concordancia entre la histología del CCNM apreciada en la biopsia preoperatoria y la siguiente muestra tumoral obtenida de la cirugía micrográfica de Mohs (MMS) en la población latinoamericana. OBJETIVO: El objetivo de este estudio fue analizar y comparar el subtipo histológico de las biopsias incisionales revisadas por el dermato-patólogo, con el subtipo histológico de la muestra tumoral obtenida durante la MMS, interpretada por el dermato-patólogo y el cirujano. MÉTODOS: Se realizó un análisis retrospectivo de 320 CCNM. La correlación inter-observador se basó en los valores kappa. RESULTADOS: El valor medio ponderado kappa entre la biopsia preoperatoria del CCNM y el subtipo histológico intraoperatorio de la muestra tumoral obtenida de la MMS, analizadas por el cirujano y el dermato-patólogo, fue de 0,22 y 0,24, respectivamente. La correlación en el subtipo histológico de la muestra tumoral intraoperatoria para MMS, interpretada por el dermo-patólogo y el cirujano, fue de 0,58. CONCLUSIONES: Los dermatólogos deben ser conscientes del valor limitado de las biopsias incisionales para diagnosticar de manera precisa el subtipo histológico del CCNM. La tasa de concordancia del diagnóstico histológico de las muestras tumorales obtenidas durante la MMS, entre el cirujano y el dermato-patólogo, fue moderada. Sin embargo, la correlación es baja cuando se compara con los subtipos obtenidos de la biopsia incisional
