Transcriptome of capsular contracture around breast implants mimics allograft rejection: a matched case-control study.

Plast Reconstr Surg

December 2024

Copenhagen University Hospital, Department of Plastic Surgery and Burns Treatment, Rigshospitalet, Copenhagen, Denmark.

Background: Capsular contracture is a frequent and severe complication following breast implant surgery. Although several theories on the pathophysiology exist, the exact molecular mechanisms remain unclear. This study aimed to identify the specific genes, signaling pathways, and immune cells associated with capsular contracture.

Article Synopsis
  • Facial transplantation (FT) aids in severe facial defects by using complex tissues, making oral health crucial for successful outcomes, but there's limited research in this area.
  • A systematic review identified 19 relevant studies out of nearly 7,000 articles, with most cases being male and originating from the U.S. and France, highlighting common oral issues like malocclusion.
  • Routine oral health evaluations are vital for FT patients to avoid complications, but more high-quality research is necessary to set standardized care practices.

Long-term survival has improved in kidney transplant recipients (KTRs) due to effective surgical techniques and anti-rejection therapies. Chronic immunosuppression associated with it has led to several types of skin cancers leading to substantial morbidity and mortality. Structured patient education including sun protective behaviors, regular dermatological surveillance, nicotinamide, long-chain omega-3 polyunsaturated fatty acids (PUFAs), early switch to mammalian target of rapamycin inhibitors (mTORis), combining them with low-dose calcineurin inhibitors (CNIs), can decrease the cancer risk.

Vascularized composite allotransplantation (VCA) represents a clinical challenge for transplant therapy, as it involves different tissues with unique immunogenicity. Even when receiving immunosuppressive therapy, they are more vulnerable to severe hypoxia, microvascular damage, and ultimately the rejection or chronic graft dysfunction after transplantation. This study aimed to develop a surgical protocol for VCA of the ear in a porcine biomodel in the absence of immunosuppression, maintaining the in vitro co-culture of the allograft and assessing their relationship with allograft survival.

26 Years of Skin Banking in Finland.

Eur Burn J

December 2024

Helsinki Burn Centre, Department of Plastic Surgery, Helsinki University Hospital and University of Helsinki, 00029 Helsinki, Finland.

Autologous skin grafts are the gold standard for definitive wound coverage in burn care, but allograft skin grafts are essential for providing temporary coverage in cases of extensive burns. The Helsinki Skin Bank, established in 1995 at the Helsinki Burn Centre, is Finland's only licensed skin bank, serving a population of 5.5 million.
