ABSTRACT
Se revisan los recientes avances en el conocimiento del proceso de cicatrización de heridas y los factores que lo afectan, lo que lleva a un cambio importante en el tratamiento y manejo de las heridas. Consideraciones relevantes, especialmente en las heridas crónicas, son la conservación de un ambiente húmedo, una correcta debridación y evitar el uso de antisépticos. Se revisan los apósitos clasificados según su ubicación en primarios y secundarios y, según su acción, en pasivos y activos.
Recent knowledge and advances in the healing process of wounds and involved factors are reviewed. This has led to important changes in the treatment and management of skin wounds. Important considerations, specially in chronic wounds, are the preservation of a humid environment, good debridement and avoidance of antiseptics. We present a review of dressing classifications, according to their location in primary and secondary or, according to their action, in active and passive.

Las formulaciones tópicas de vitamina C y E han demostrado su efectividad en la prevención del fotodaño de la piel. El uso oral de vitaminas A, C, D y E presenta resultados controversiales. Se revisa la literatura, con especial énfasis en los efectos adversos del uso oral de vitaminas.

The yeast Malassezia spp has an established etiological role in pityriasis versicolor, folliculitis, systemic infections and onychomycosis. Aim: To assess the presence of Malassezia spp in patients with seborrheic dermatitis (SD), to find a correlation between Malassezia spp count and the severity of the disease and to compare the prevalence of the different Malassezia species in SD patients and subjects without skin lesions. Patients and methods: Scrapings of the face from 81 patients with SD (69 males) and 79 subjects (54 males) without skin lesions were obtained for a direct microscope examination and yeast culture. Results: The yeast Malassezia was found in 76% of SD patients and in 82% of subjects without skin lesions. There was a positive correlation between the number of yeasts found on direct examination and the clinical severity of lesions in SD patients. Although this correlation was statistically significant (p=0.046), the degree of association (rho=0.22) was weak. Fifty Malassezia species were identified. M globosa was found in 67% of SD patients, followed by M furfur and M sympodialis, each present in 16.5% of the SD patients. In subjects without skin lesions, the most prevalent species were M globosa (77%), followed by M sympodialis (12%), M slooffiae (7%) and M furfur (4%). Conclusions: The presence of the yeast Malassezia is not associated with the presence of skin lesions (Rev Méd Chile 2003; 131: 1295-300).

Herpes gestationis es una rara enfermedad autoinmune que se presenta en mujeres embarazadas, compromete principalmente la piel y puede manifestarse como lesiones bulosas intensamente pruriginosas que, en ocasiones, son de difícil diagnóstico. Nosotros reportamos 2 casos clínicos simultáneos que se presentaron en nuestro servicio en marzo del año 2002, hecho que no deja de sorprender dado lo infrecuente y poco común de esta patología
