ABSTRACT
Keratosis pilaris is a common dermatosis observed in daily dermatologic practice. The diagnosis is clinical and usually asymptomatic, although sometimes patients may complain of mild pruritus and its cosmetic appearance. Few reports exist about its treatment. There are clinical trials assessing topical treatments and laser surgery, but no systematic reviews on its management were found in literature. An online research was conducted to identify evidence-based recommendations. Lactic acid, salicylic acid, and the 1064-nm Nd:YAG laser seem to be the most effective and safe treatment options for keratosis pilaris among patients aged 12 years and older; however, high-quality randomized controlled trials with long-term outcomes are required.

OBJECTIVE: To know the prevalence of sun exposure and protection behaviors in a group of adolescents and to compare them with a group of adults in Mexico City. MATERIAL AND METHODS: Descriptive, cross-sectional study in students aged 16 to 18 years and in adults older than 18 years. RESULTS: Seven-hundred and forty-eight students were surveyed; 60 % were females and 40 % males; 90 % seek shade, 70.1 % avoid exposing themselves to the sun from 10.00 to 16.00 hours and 30.6 % use sunscreen. Out of 620 adults, 67.5 % were women and 32.4 % were men; 82.6 % seek shade, 60.2 % avoid the sun from 10.00 to 16.00 hours and 48.1% use sunscreen; 72.9 % of adults and 80.8 % of adolescents are exposed to the sun due to domestic activities. DISCUSSION: There is a similar trend in sun protection and exposure behaviors in adolescents and adults. The prevalence of sunscreen use in adults is high in comparison with adolescents.

INTRODUCTION: Dermoscopy is a tool that aids clinicians in the diagnosis of actinic keratosis; however, few diagnostic accuracy studies have determined its sensitivity and specificity for this diagnosis. OBJECTIVE: Determine the diagnostic accuracy of dermoscopy on actinic keratosis. METHODS: A systematic review was conducted on EMBASE, PubMed, Scopus and the Cochrane Central Registry of Controlled Trials from inception to August 2019. RESULTS: We screened 485 titles and abstracts. Two studies comprising 219 actinic keratoses were eligible for qualitative analysis. The number and heterogeneity of included studies limited a quantitative analysis. CONCLUSIONS: Studies that focus specifically on the diagnostic accuracy of dermoscopy for actinic keratosis are lacking.
ABSTRACT
BACKGROUND: There is heterogeneity in the design of clinical trials (CT) for the treatment of keloid scars that compromises the validity of their results. OBJECTIVE: To assess the methodological quality of the CT published on keloid scars, mainly the outcomes used in them. METHOD: Articles of CT for keloid scars were analyzed, their methodological quality was evaluated following the CONSORT guidelines and the risk of bias based on the Cochrane tool. All the clinical outcomes measured in CT were identified. RESULTS: Fifty-two full-text articles were evaluated, of which, only 3.84% of the CT mentioned important changes in the methodology after starting patient recruitment. Fifty-nine percent of the CT were assessed as high risk of performance bias due to mistakes in blinding participants and personnel. The most frequent outcome was the height or thickness of the keloids. CONCLUSIONS: We recommend that participants with hypertrophic scars should be excluded from keloids' clinical trials, and that the main outcome must be the scar height and flattening. The pain and quality of life of patients should also be measured.
ANTECEDENTES: Existe heterogeneidad en el diseño de los ensayos clínicos (EC) para el tratamiento de cicatrices queloides que compromete la validez de sus resultados. OBJETIVO: Evaluar la calidad metodológica de los EC publicados sobre cicatrices queloides, principalmente las medidas de eficacia utilizadas. MÉTODO: Se analizaron los EC publicados sobre tratamientos para cicatrices queloides y se evaluó su calidad metodológica siguiendo los lineamientos CONSORT y el riesgo de sesgo según la herramienta de Cochrane. Se identificaron todas las medidas de eficacia utilizadas en los EC. RESULTADOS: Se incluyeron 52 artículos, de los cuales solo en el 3.84% se mencionan los cambios importantes en la metodología después de iniciar el reclutamiento de los pacientes. El 59.6% de los EC fueron evaluados con alto riesgo de sesgo de realización por errores en el cegamiento del equipo de investigación. La variable de respuesta más frecuente fue la altura o grosor de las cicatrices. CONCLUSIONES: Se recomienda que en los EC de cicatrices queloides se excluya a los participantes con cicatrices hipertróficas, y que la variable de resultado principal sea la altura de la cicatriz. También deben medirse el dolor y la calidad de vida de los pacientes.

INTRODUCCIÓN: Las cicatrices queloides afectan hasta el 16% de la población hispana y pueden causar un deterioro en la calidad de vida. La mayoría de los estudios previos han estudiado pacientes con cicatrices hipertróficas secundarias a quemaduras. OBJETIVO: Determinar la calidad de vida en adultos con cicatrices queloides que acuden a un centro dermatológico. MÉTODO: Se realizó un estudio transversal analítico en el Centro Dermatológico Dr. Ladislao de la Pascua, en adultos con diagnóstico de cicatrices queloides. Se midió la calidad de vida mediante el instrumento DLQI (Dermatology Life Quality Index) y se estudiaron las siguientes variables clínicas: edad, sexo, tiempo de evolución, tamaño de la cicatriz, número de cicatrices y topografía afectada. Se aplicó el cuestionario de Beck para el tamizaje de la depresión. RESULTADOS: Se reclutaron 106 adultos con cicatrices queloides (61% hombres y 39% mujeres), con una mediana de edad de 26 años (rango intercuartilar: ±18 años). El puntaje promedio del DLQI fue de 5.58 (desviación estándar [DE]: ± 5.528), con un máximo obtenido de 22 puntos; dicho puntaje se interpreta como un deterioro mínimo de la calidad de vida. La dimensión que más contribuyó al total del puntaje fue la de síntomas y sentimientos, con el 50.36%. El número de cicatrices y la edad se asociaron directamente con el puntaje del DLQI. El puntaje promedio obtenido con el cuestionario de Beck fue de 6.45 (DE: ± 6.46 puntos) y se correlacionó con el puntaje del DLQI. CONCLUSIONES: Las cicatrices queloides tienen un efecto negativo mínimo en la calidad de vida. Dicho efecto se asoció al autorreporte de síntomas depresivos; sin embargo, los resultados de este estudio no permiten atribuirle una relación casual. Se recomienda aplicar el cuestionario de calidad de vida en adultos jóvenes con cicatrices. INTRODUCTION: Keloid scars affect up to 16% of the Hispanic population and may cause deterioration in the quality of life. Most of the previous studies have focused on patients with hypertrophic scars secondary to burns. OBJECTIVE: To determine the quality of life in adults with keloid scars that go to a dermatological center. METHODS: An analytical cross-sectional study was carried out at Centro Dermatológico Dr. Ladislao de la Pascua in adults with a diagnosis of keloid scars. The quality of life was measured using the Dermatology Life Quality Index (DLQI) and the following clinical variables were studied: age, sex, evolution time, scar size, number of scars and affected topography. The Beck questionnaire for depression was also applied. RESULTS: 106 adults with keloid scars were recruited, 61% men and 39% women, with a median age of 26 years (interquartile range: ± 18 years). The average score of the DLQI was 5.58 (standard deviation [SD]: ± 5.528), with a maximum obtained of 22 points, this score is interpreted as a minimum or small deterioration of the quality of life. The dimension that contributed most to the total score was symptoms and feelings, with 50.36%. The number of scars and age were directly associated with the DLQI score. The average score obtained with the Beck questionnaire was: 6.45 (SD: ± 6.46 points) and it correlates with the DLQI score. CONCLUSIONS: Keloid scars have a minimal negative effect on the quality of life of young adults. This effect was associated with the self-report of depressive symptoms; however, the results of this study do not allow to attribute a causal relationship. It is recommended to apply the quality of life questionnaire in young adults with scars.
