RESUMO
Irradiated wounds are characterized by a slow healing process. Insulin-like growth factor-1 (IGF-1), a somatomedin C, has been shown in previous studies to stimulate collagen synthesis and bony repair. The purpose of this investigation is to evaluate the potential beneficial effects of recombinant IGF-1 in the healing of critical size calvarial defects in previously irradiated adult male Sprague-Dawley rats.

The changes in the abdomen due to pregnancy, aging and overweight are responsible for functional and aesthetic disorders. Aesthetic surgery is suitable in selected cases. The abdominal plasty procedures can be of long or limited extension depending on the case. Their purposes are to strength the muscle-aponeurose layers, take out the excess of fat and leave the skin with normal tension. These procedures make disappear the stretch marks only within the skin area that is excised. The liposuction has transformed these abdominal plasty procedures by diminishing the length of skin to be resected, and so, reducing the aesthetic disorder.

In the context of cervical facelift, classical techniques, constituting the basis for current techniques or still in use, are described in terms of the incisions, detachments and treatment of the deep adipose, muscular and glandular planes. The author then describes the technique commonly used in modern cervical restructuration before describing the possible complications and defects.

By improving the quality of the results and by allowing an extension of the indications of abdominal plasty, liposuction transforms this operation into a true "aesthetic" procedure. The umbilicus is no longer a closed lock and its treatment allows classification of abdominal plasties into abdominiplasties which concern the infraumbilical abdomen and abdomaxiplasties, involving the entire abdomen with reimplantation or repositioning of the umbilicus.
