Y-shaped venous anastomosis combined with free flap for the treatment of complex craniofacial trauma.

J Stomatol Oral Maxillofac Surg

January 2025

Department of Burns and Plastic Surgery, Affiliated Hospital of Zunyi Medical University, 563000 China; The Collaborative Innovation Center of Tissue, Damage Repair and Regeneration Medicine of Zunyi Medical University, 563000 China. Electronic address:

Background: Complex craniofacial trauma is defined as those traumatic injuries that are not responding to initial treatment and may involve chronic infection, tissue exposure, and soft tissue contusions. Typical reconstruction using a Y-shaped microvascular venous anastomotic free flap is labor intensive. Although free flap grafts have been used in many applications, their use for combined microvascular anastomotic therapy remains an unexplored but attractive possibility.

Autologous hematopoietic stem cell transplantation is used to restore bone marrow function after high-dose chemotherapy. For apheresis, granulocyte colony-stimulating factor (G-CSF) is standard of care, but obtaining sufficient stem cells can be challenging. Other mobilization agents include plerixafor and PEGylated G-CSF (PEG-G-CSF).

Peripheral nerve injury repair has always been a research concern of scientists. At the tissue level, axonal regeneration has become a research spotlight in peripheral nerve repair. Through transplantation of autologous nerve grafts or other emerging biomaterials functional recovery after facial nerve injury is not ideal in clinical scenarios.

Aim: This study aimed to evaluate the impact of pterygium excision combined with autologous limbal stem cell transplantation on microvascular density, tear film stability, and corneal wound healing in the management of pterygium.

Methods: A retrospective analysis was conducted on 317 patients with pterygium who underwent treatment between January 2021 and January 2024. Patients were divided into a control group (pterygium excision alone, n = 161) and a study group (pterygium excision combined with autologous limbal stem cell transplantation, n = 156) based on the surgical approach.

Donor-derived GD2-specific CAR T cells in relapsed or refractory neuroblastoma.

Nat Med

January 2025

Department of Hematology/Oncology, Cell and Gene Therapy, Scientific Institute for Research, Hospitalization and Healthcare (IRCCS), Bambino Gesù Children's Hospital, Rome, Italy.

Allogeneic chimeric antigen receptor (CAR) T cells targeting disialoganglioside-GD2 (ALLO_GD2-CART01) could be a therapeutic option for patients with relapsed or refractory, high-risk neuroblastoma (r/r HR-NB) whose tumors did not respond to autologous GD2-CART01 or who have profound lymphopenia. We present a case series of five children with HR-NB refractory to more than three different lines of therapy who received ALLO_GD2-CART01 in a hospital exemption setting. Four of them had previously received allogeneic hematopoietic stem cell transplantation.
