Missed Distal Femoral Cortical Perforation During Intramedullary Nailing of an Intertrochanteric Femur Fracture: The Role of Early Advanced Imaging.

Distal femoral anterior cortical perforation is a rare complication of intramedullary nailing for proximal femur fractures. Awareness and intraoperative preventive measures are key to minimizing the risk of this complication. We report a case of a patient who experienced an anterior cortical breach of the distal femur during routine antegrade nailing for an intertrochanteric fracture, which was attributed to a sclerotic lesion in the distal femur.

DiffMAP-GP: Continuous 2D Diffusion Maps from Particle Trajectories without Data Binning using Gaussian Processes.

Diffusion coefficients often vary across regions, such as cellular membranes, and quantifying their variation can provide valuable insight into local membrane properties such as composition and stiffness. Toward quantifying diffusion coefficient spatial maps and uncertainties from particle tracks, we develop a Bayesian framework (DiffMAP-GP) by placing Gaussian Process (GP) priors on the family of candidate maps. For sake of computational efficiency, we leverage inducing point methods on GPs arising from the mathematical structure of the data giving rise to non-conjugate likelihood-prior pairs.

Outcomes of Open-Globe Injuries With Associated Retinal Detachment: Experience at an Ocular Trauma Center.

To characterize the clinical features and outcomes of open-globe injuries with associated retinal detachment (RD). A retrospective review was performed. Thirty-six patients with open-globe injuries and subsequent rhegmatogenous RD were analyzed between January 2016 and September 2021.

Postoperative Complications of Direct-to-Implant and Two-Staged Breast Reconstruction: A Stratified Analysis.

Post-mastectomy implant-based reconstruction can be performed as direct-to-implant (DTI) or two-staged reconstruction (TSR). Rigorous studies have explored postoperative complications between TSR or DTI, yet few have stratified outcomes by relevant populations, pre-operative findings, mastectomy characteristics, or plane of implant placement. We sought to compare the outcomes between these cohorts at our institution.
