Preoperative hypovitaminosis D and complications in plastic surgery: a pilot study.

Introduction: Vitamin D plays a crucial role in various biological processes, including the well-known regulation of the immune system and calcium metabolism. While its involvement in the surgical outcomes of various medical specialties is recognized, there is a lack of consistent data regarding plastic surgery. This study aimed to assess preoperative serum levels of 25-hydroxyvitamin D and its relationship with complications in patients undergoing reconstructive and aesthetic plastic surgeries.

Evaluation of Sensitivity in Specific Points of the Areola and Nipple of Patients Submitted to Reduction Mammoplasty With Periareolar Dermis Release: A Randomized Controlled Study.

Background: To date, studies on periareolar dermis release have recorded the areola sensitivity as a mean. Despite being clinically reported by patients, specific points of the areola may present sensitivities not detected when researchers only consider mean values.

Objectives: The aim of this study was to determine the pressure sensitivity at specific points of the nipple-areola complex and compare these values with the mean value measured in the areolas of patients undergoing reduction mammaplasty with periareolar dermis release.

Sensitivity of the Nipple-Areola Complex in Reduction Mammaplasty Following Periareolar Dermis Section.

Background: Preservation of the periareolar dermis, after de-epithelization in reduction mammaplasty, may result in reduced nipple-areola complex (NAC) mobility. Consequently, distortion in shape and difficulty correcting the areola position can occur.

Objectives: The aim of this study was to evaluate NAC viability and sensitivity resulting from periareolar dermis section after de-epithelization in patients who underwent reduction mammaplasty surgery.

The effects of local nitroglycerin on the surgical delay procedure in prefabricated flaps by vascular implant in rats.

Purpose: To evaluate the effect of local nitroglycerin on the viable area of a prefabricated flap for vascular implant in rats, and to investigate the surgical delay procedure.

Methods: A femoral pedicle was implanted under the skin of the abdominal wall in forty Wistar rats. The animals were divided into four groups of ten: group 1 - without surgical delay procedure and local nitroglycerin; group 2 - with surgical delay procedure, but without local nitroglycerin; group 3 - without surgical delay procedure, but with local nitroglycerin; and group 4 - with simultaneous surgical delay procedure and local nitroglycerin.
