The techniques of reduction mammoplasty are multiple and varied. Each one has advantages and disadvantages. With any of them, full preservation of vascularity and sensitizing of the nipple-areola complex (NAC) should be sought, as well as functionality of the breast. We present our 15 years' experience using the superolateral dermoglandular pedicle, a technique that fully preserves the integrity of the breast. During that 15-year period, we operated on 702 breasts in 356 patients, using the superolateral dermoglandular pedicle, with the NAC requiring a migration of 5 to 16 cm (mean: 9.2 cm), having resected breast tissue between 300 and 1380 g, (average: 660 g). The technique was used in women between 16 and 63 years of age (average 37), who wanted breast reduction and who required a migration of the NAC greater than 5 cm. We had minor complications consisting of wound dehiscence (5.9%), scar hyperpigmentation (3.9%), fat necrosis (3.8%), hypertrophic scarring (3.1%), alterations in sensitivity (2.27%), and keloid scarring (0.5%). We had 9 cases of necrosis of the NAC (1.28%), of which 7 were partial (0.99%) and 2 were total (0.28%). Satisfaction with the results was 94%. The technique of reduction mammoplasty with a superolateral dermoglandular pedicle has been used in mammary hypertrophy and gigantomasty with excellent results. Its design is simple, its performance easy, and its aesthetic results are highly reproducible. The position of the pedicle allows full preservation of the vascularity, sensitivity, and functionality of the breast, and is therefore a highly recommendable technique.

Se hizo una revisión sobre la esteatohepatitis no alcohólica, la cual durante años fue considerada una enfermedad poco común y de buen pronóstico. Sin embargo, el conocimiento de que entre 15 y 50 por ciento de los pacientes presentan fibrosis y hasta cirrosis en sus biopsias, hizo que cambiara esa percepción, y en estos momentos es una de las entidades a las que más atención se le está prestando dentro del campo de la Hepatología. A pesar de que la fisiopatogenia de esta entidad es compleja y no bien elucidada aún, la teoría de los 2 hits, propuesta en 1998, explica los principales mecanismos fisiopatogénicos implicados en su desarrollo. Existen varios modelos experimentales para el estudio de la esteatohepatitis no alcohólica. No obstante, el modelo animal que reproduce con mayor fidelidad la fisiopatogenia de la esteatohepatitis no alcohólica es el logrado por Lieber y otros a partir del empleo en ratas de una dieta líquida rica en grasas(AU)

A newborn infant with subcutaneous fat necrosis after perinatal hypoxia was found to have several abnormalities of plasma lipids. Further studies are needed to determine whether such abnormalities contribute to the pathophysiology of the skin lesions.
