ABSTRACT

Mostramos un caso de dermatosis profesional originado por plásticos (resinas epoxi) y la importancia de la detección precoz. Las resinas epoxi son de gran utilización en todo tipo de industrias (artes graficas, construcción, electrónica, componentes de prótesis traumatológicas, prótesis odontológicas, etc.) y sus componentes pueden ser causa de dermatitis de contacto irritativa y por sensibilización.


We describe a case of professional dermatosis caused by exposition to plastic products (epoxy resin) and importance of early detection. The epoxy resins are widely used in all types of industries (graphics arts, construction, electronics, traumathological and odontological prothesis, etc.) and their components may be the cause of contact dermatitis and sensitivity. Risk factors at work with epoxy resins are present during the production base resins, hardening agents, plasticizers and dilutants increase the risk of exposition at work. This requires preventive measures and early diagnosis.

ABSTRACT

Estudios antropológicos, etnológicos y arqueológicos muestran la evolución del cuidado de la piel desde la prehistoria. La preocupación del hombre por su aspecto estético se inicia con la humanidad misma. A través del tiempo se buscaron fórmulas cada vez más efectivas, para prolongar las condiciones de juventud y belleza. El aspecto estético de la piel siempre se relacionó con la buena salud. En la actualidad el dermatólogo posee sobrados elementos para recuperar y resaltar la salud y el cuidado de la piel.


Anthropologists and archeologists have traced the evolution of skin care since prehistory. The human concern for his aesthetic appearance dates since the beginning of humanity. Through time, more and more efficient formulations were looked for to extend youthfulness and beauty. An aesthetic skin has always been synonymous with health and at the present time the dermatologist has many resources to improve and acentuate the good quality of the skin.

ABSTRACT

Los polifenoles (flavonoides y antocianinas) están ampliamente distribuidos entre las diferentes especies vegetales. Estos poseen gran capacidad antioxidante; existiendo correlación positiva entre la actividad antioxidante y los polifenoles totales. El objetivo de este trabajo fue evaluar: 1° El contenido de polifenoles y antocianas totales de semillas, glumelas y extracto acuoso de Avena sativa L. 2° El efecto de la aplicación tópica de extracto acuoso de avena en 45 casos (10 mujeres y 35 hombres, entre 1 y 56 años de edad) con dermatitis atópica, dermatitis de contacto irritativa y dermatitis de contacto alérgica; y 30 controles normales (15 mujeres y 15 hombres, entre 1 y 60 años de edad). Tratamiento: aplicación de compresas del extracto crudo de avena en la piel dañada durante 5 minutos, seguida de la colocación de la biomasa (T°= 33 + 2°C) cubierta por una tela de gasa durante 5 minutos. Dicha biomasa se retira con el extracto de avena líquido. Entre 1 y 36 meses de iniciado el tratamiento se observó remisión de los síntomas cutáneos. El extracto acuoso, la biomasa de Avena sativa L., glumelas y semillas enteras contenían 6.12+0,45, 46,11+0,36, 212,81+0,19 y 286,60+0,50 mg/100 g ác. Gálico, respectivamente, de polifenoles totales.


Polyphenols (flavonoids and anthocyanins) are widely spread among the different vegetables species. They have a big antioxidant capacity. One important correlation exists between the antioxidant activity and the quantity of total polyphenols. The objective of this work was to evaluate: 1- the contents of polyphenols and anthocyanins of whole seeds, glumes and aqueous extract of Avena Sativa L., 2- the effects of topical application of aqueous extract of Avena sativa L. in 45 patients (10 females and 35 males, between 1 and 56 years olds) with Atopic Dermatitis, Contact Irritative Dermatitis and Contact Allergic Dermatitis, and 30 normal controls (15 females and 15 males, between 1 and 60 years olds). Treatment: were applications of compress of aqueous extract Avena Sativa L over the damaged skin for approximately five minutes, immediately after, one must cover with the biomass of oat (T° = 33 + 2 C°) and a clothe for five minutes. The biomass was removed using the Avena Sativa L. acqueous extract. Remissions of the cutaneous symptoms were noticed between 1 and 36 months after the beginning of the treatment. Aqueous extract, Avena Sativa L. biomass, glumes and whole seeds contents were: 6.12+0.45; 46.11+0.36, 212.81+0.19 y 286.60+0.50 mg/100 g gallic ac., respectively, of total polyphenols.
