Novel 3D/VR interactive environment for MD simulations, visualization and analysis.

The increasing development of computing (hardware and software) in the last decades has impacted scientific research in many fields including materials science, biology, chemistry and physics among many others. A new computational system for the accurate and fast simulation and 3D/VR visualization of nanostructures is presented here, using the open-source molecular dynamics (MD) computer program LAMMPS. This alternative computational method uses modern graphics processors, NVIDIA CUDA technology and specialized scientific codes to overcome processing speed barriers common to traditional computing methods.

Longer length Baha™ abutments decrease wound complications and revision surgery.

Objectives/hypothesis: To study the complication rates of skin overgrowth, infection, and the need for revision surgery in longer length Baha™ abutments.

Study Design: Prospective observational cohort study compared with a retrospective historical control.

Methods: After the University of Nebraska Medical Center (UNMC) Institutional Review Board approval was obtained, data was collected from a prospective 8.

Smell and taste disorders.

Olfaction and taste promote satisfaction and protection in daily life. The astute facial plastic surgeon recognizes the importance of a baseline smell test to document the patients' olfactory status before surgery. After surgery, the surgeon must be alert to the possible mechanisms of hyposmia and anosmia and the pertinent treatment strategies.

Hypopharyngeal diverticulum formation following anterior discectomy and fusion: case series.

Pharyngoesophageal diverticulum is a rare complication following anterior cervical discectomy and fusion (ACDF). Dysphagia is a well-documented complication associated with ACDF. It may result postoperatively from a variety of etiologies, including hardware displacement, pharyngeal edema, or vocal fold paresis.
