In a fifteen-year-old girl, bilaterally impacted permanent maxillary canines were established. A difficult palatinal placement and an apical deviation were found in both teeth. Surgical exposure of the canines, followed by orthodontic traction was not desirable. Both remaining primary canines showed signs of resorption. Autogenous transplantation of the maxillary canines was the treatment chosen.

While silk fibroin (SF) obtained from silkworm cocoons is expected to become a next-generation natural polymer, a fabrication method for SF-based artificial nerve conduits (SFCs) has not yet been established. Here, we report a bioresorbable SFC, fabricated using a novel freeze-thaw process, which ensures biosafety by avoiding any harmful chemical additives. The SFC demonstrated favorable biocompatibility (high hydrophilicity and porosity with a water content of > 90%), structural stability (stiffness, toughness, and elasticity), and biodegradability, making it an ideal candidate for nerve regeneration.

Introduction: The strategy of adipose component transplantation has been proposed and widely used in both reconstructive and aesthetic surgery. However, there is no uniform standard for the preparation of component fat, and the volume calculation of liposuction and injection in clinical applications is mostly based on experience. This study aims to analyze the volume of component fat obtained during clinical series.

Objective: The objective of this study was to assess the maturation of matrix-associated autologous chondrocyte transplantation (MACT) grafts up to 2 years after the surgery using gray-level co-occurrence matrix (GLCM) texture analysis of quantitative T maps, compare the results with the microfracturing technique (MFX) control group, and relate these results to the morphological MOCART 2.0 score.
Design: A subcohort of 37 patients from prospective, multi-center study underwent examination on a 3T MR scanner, including a T mapping sequence at 3, 12, and 24 months after surgery.

Introduction: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a very rare disease, with unique diagnostic challenges and often dismal outcome. There are no widely accepted treatment guidelines available. Lymphoma-like regimens with or without autologous or allogenic transplantation were the cornerstone of most therapeutic concepts.

Background: Cold agglutinin disease (CAD) or syndrome (CAS) can be particularly challenging when autologous stem cell transplant (ASCT) is needed. Standard peripheral blood stem cell (PBSC) collection and manipulation involve ex vivo blood manipulations at lower than body temperature, predisposing to agglutination during graft collection, handling, processing, and infusion.
Study Design And Methods: We describe the first case of ASCT for relapsing lymphoma in a patient with high-titer CAD requiring anti-complement therapy and chronic transfusion.
