Research for new biocompatible and easily implantable materials continously proposes new molecules and new substances with biological, chemical and physical characteristics more and more adapted to aesthetic and reconstructive surgery. Bio-Alcamid (Polymekon, Italy) is a non reabsorbable polymeric material composed of alkylimide-amide groups. This cosmetic agent has been used for the treatment of 2000 patients by a multicentric trial led by different Hospitals and University in Italy and abroad. Very serious aesthetic defects such as pectus excavatum, Poland Syndrome, postoperative traumas, in addition to common aesthetic defects such as lips, cheek-bone and chin hypovolumetry and relaxing of nasolabial sulcus, have been treated by surgical implant of Bio-Alcamid. Aesthetic results were excellent; tissues felt soft and the implants were uniformly distributed. No migration or dislocation of the implants, no granulomas, no allergic response and no kind of intolerance were observed. Only 12/2000 patients had post-operative complications (Staphylococcus infections) and only 3/12 cases could be directly ascribed to the implanted material. For its characteristics Bio-Alcamid can be considered a novelty in the aesthetic and reconstructive surgery; it is absolutely biocompatible, non toxic, non allergenic, easily injectable and quickly removable. Bio-Alcamid can be defined a sort of "endoprosthetis", perfectly suitable for soft tissue augmentation and for the correction of different tissue deficiences, with a long-term safety and efficiency.

Prognosis of Implant-Based Breast Reconstruction After Mastectomy Flap Necrosis: Predictors of Failure and Salvage.
Aesthetic Plast Surg
January 2025
Department of Plastic Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, 81 Irwon-ro, Gangnam-gu, Seoul, 06351, Republic of Korea.
Background: In the realm of implant-based breast reconstruction, mastectomy flap necrosis (MFN) is a prevalent yet grave complication that poses a threat to the stability of the inserted prosthesis. Although numerous investigations have scrutinized the risk factors for MFN development, few have delved into the aftermath, specifically implant failure or salvage. This study seeks to appraise the prognosis of the implanted prosthesis following MFN occurrence, as well as identify predictors of such outcomes.

Background: Medical tourism is a rapidly expanding multi-billion-dollar industry. Reduced costs, all-inclusive vacation packages that include cosmetic surgery, globalization, and affordable flight expenses have encouraged patients to seek aesthetic procedures in different countries. Cosmetic medical tourism is associated with high complication rates, such as severe infections, wound dehiscence, pain or discomfort, aesthetic dissatisfaction, and even death.

Introduction: Reconstructing large bone defects for lower limb salvage in the pediatric population remains challenging due to complex oncological or septic issues, limited surgical options, and lengthy procedures prone to complications. The vascularized double-barreled fibula free flap is pivotal for reconstructing large bones. In this article, we report our experience with this technique in the surgical management of pediatric tibial bone defects.

Introduction: Graft optimization is a necessity in order to develop uterus transplantation from brain-dead donors, as a complement to living donors, as these grafts are rare and the last organs retrieved in multiple organ donation. The aim of this study was to assess the feasibility and interest of hypothermic machine perfusion (HMP) in uterus transplantation using a porcine model; secondary outcomes were the evaluation of the graft's tolerance to a prolonged cold ischaemia time and to find new biomarkers of uterus viability.
Material And Methods: Fifteen uterus allotransplantations were performed in a porcine model, after 18 h of cold ischaemia, divided in three groups: Static cold storage in a HTK solution, HMP (with the VitaSmart (™) machine Bridge to Life Ltd.
