We here report on the surgical procedure, postoperative course and functional results at 3 years following the first bilateral forearm transplantation. A 41-year-old male underwent bilateral forearm transplantation on February 17, 2003. After ATG induction therapy, tacrolimus, prednisone and MMF were given for maintenance immunosuppression. At 16 months, MMF was switched to everolimus. Hand function, histology, immunohistochemistry, radiomorphology, motor and nerve conduction and somatosensory-evoked potentials were investigated at frequent intervals. A total of six rejection episodes required treatment with either steroids, basiliximab, ATG, alemtuzumab or tacrolimus dose augmentation. At 3 years, the patient is free of clinical signs of rejection despite a persisting minimal perivascular lymphocytic dermal infiltrate. No signs of myointimal proliferation in graft vessels were seen. Motor function continuously improved, resulting in satisfactory hand function. Intrinsic hand muscle function was first observed at 16 months and continues to improve. Although discrimination of hot and cold recovered, overall sensitivity remains poor. The patient is satisfied with the outcome. Bilateral forearm transplantation represents a novel therapeutic option after loss of forearms.

Introduction: A common complication of arteriovenous fistula (AVF) is thrombosis in the venous segment, which can impair vascular access unless a successful thrombectomy is performed.
Case Presentation: In this manuscript, we describe the case of a diabetic patient who had primary AVF in a snuff-box with subsequent superficialization of the medial vein of the forearm. Unfortunately, this section of the vein was occluded, although the fistula was patent through the cephalic vein (CV).

Background: Vascular thymus transplantation has been explored in animal models but remains untested in humans. Current approaches to congenital athymia involve avascular transplantation of allogeneic thymic tissue, which may delay immune recovery. Building on animal studies, we propose revascularization of thymic tissue in a human model.

Background: Modern nerve-to-nerve transfers are a significant advancement in peripheral nerve surgery. Nerve transfers involve transferring donor nerves or branches to recipient nerves close to the motor end unit, leading to earlier reinnervation and preservation of the musculotendinous units in proximal nerve injuries. After nerve reinnervation, function may be superior to traditional tendon transfer techniques in terms of strength and independent motion.

Negative-pressure wound therapy (NPWT) is used to promote wound closure or to prepare a wound for definite coverage. However, the anatomy of the hand makes it difficult to apply dressings that require an airtight seal. In this report, the authors describe the case of a patient with an extensive defect of his right hand and forearm who was treated with a free fibula osteocutaneous flap transfer.

Article Synopsis
- The study looks at trends and outcomes of parathyroid autotransplantation (PTAT) in children undergoing total thyroidectomy, analyzing data from a surgical database.
- Of the 2,444 patients analyzed, a small percentage underwent PTAT, with the procedure being performed more frequently by adult subspecialists and in cases with more extensive lymph node removal.
- The overall use of PTAT declined over the study period, and no significant differences in early postoperative complications or hospital stays were noted between those who had PTAT and those who did not.
