[Merkel cell carcinoma in lower end].

Merkel cells carcinoma is a rare cutaneous neoplasia. Studies revealed an increase in the occurrence from 0.15 to 0.

Immunohistochemical expression of apoptosis and VEGF expression on random skin flaps in rats treated with hyperbaric oxygen and N-acetylcysteine.

Objective: We sought to investigate the role of hyperbaric oxygen (HBO2), N-acetylcysteine (NAC), and HBO2 plus NAC (HN) on the immunohistochemical expression of caspase-3 and the vascular endothelial growing factor (VEGF) on random skin flaps of rats (modified McFarlane design).

Methods: Thirty-two male Wistar rats were randomly divided into four groups: GS (sham--n = 8); GNAC (N-acetylcysteine--n = 8); GHBO2 (hyperbaric oxygen--n = 8); and GHN (HBO2 plus NAC--n = 8). A rectangular skin flap (2 x 8 cm2) was dissected from the muscular dorsal layer, preserving a cranial pedicle.

Malar fat pad repositioning in facelifting: a simple technique of suspension and fixation.

Background: Aging in the malar fat pad is mainly caused by ptosis of the fibroadipose layer. In the lower level of the face, atrophy or osseous rotation may contribute to the signs and symptoms of facial aging.

Objectives: The senior author (CYC) describes his simple technique of suspension and fixation of the malar fat pad and the jowl during facial rejuvenation surgery.

Internal suture technique for improving projection and stability in secondary gluteoplasty.

The most common indication for primary gluteoplasty is the aesthetic correction of gluteal hypoplasia; secondary gluteoplasty is directed toward asymmetry from misplaced implants, trauma or infection of the implant, and treatment of congenital and acquired deformities. In this study, the authors describe a new suture maneuver designed to improve the result in secondary gluteoplasties. To reduce the empty pocket spaces and guarantee the stability of the new (smaller) implants, anchoring circular interlocking sutures are placed into the two sheets of the fibrotic capsule, which makes it possible to place the implant in a more favorable position.

[Non-Hodgkin's lymphoma of the spermatic cord].

Non-Hodgkin s lymphoma of the spermatic cord are rare. There is the registration of 14 (fourteen) cases of spermatic cord lymphoma in the literature, all treated with radical orchiectomy with or without radiotherapy. The adjuvant chemotherapy still is not a consensus, therefore the therapy must be individualized and applied according to the stage of the disease.

Treatment of the breast's lateral pole: adjuvant maneuver to Pitanguy's technique.

Surgical procedures for the mammary region currently are assuming an important role in body-contouring surgery. Enhancement of results is a constant challenge to the plastic surgeon. A simple and efficient maneuver for resection of the breast's lateral pole based on the mammoplasty technique of Professor Ivo Pitanguy is described.

Primary essential cutis verticis gyrata--a case report.

Cutis verticis gyrata (CVG) is a skin deformity characterised by excessive growth of the skin of the scalp, resulting in furrows and folds which are similar to gyri of the brain cortex. CVG can be classified into two forms: 'primary' (essential and non-essential) and 'secondary'. The primary non-essential type is associated with the neurological and ophthalmological changes, while the primary essential form does not present any other disorder except for the cutaneous alterations.
