Successful Radiofrequency Ablation of an Intrathyroidal Parathyroid Adenoma After Failed Parathyroidectomy.

Background/objective: Radiofrequency ablation (RFA) has been increasingly used as an alternative to surgery in patients with primary hyperparathyroidism who are unable or unwilling to have surgery.

Case Report: We present a case of a 64-year-old woman who had surgery for primary hyperparathyroidism complicated by osteoporosis. Preoperative imaging with 4-dimensional computed tomography scan suggested multigland disease; however, she had persistent hyperparathyroidism after parathyroid exploration.

Ambulatory surgery center versus outpatient hospitals: a comparison of reimbursements for patients undergoing anterior cervical discectomy and fusion.

Background Context: While some studies have demonstrated that ambulatory surgery centers (ASCs) are associated with reduced costs of orthopedic procedures, there is no consensus in the current literature as to the impact of ASCs versus hospital-based outpatient departments (HOPDs) on anterior cervical discectomies and fusions (ACDFs).

Purpose: This study sought to (1) compare immediate procedure reimbursements, patient out-of-pocket expenditures, and surgeon reimbursements for ACDFs performed at ASCs versus HOPDs and (2) identify factors predicting facility utilization.

Study Design: Retrospective cross-sectional study.

Whole Genomes Inform Genetic Rescue Strategy for Montane Red Foxes in North America.

A few iconic examples have proven the value of facilitated gene flow for counteracting inbreeding depression and staving off extinction; yet, the practice is often not implemented for fear of causing outbreeding depression. Using genomic sequencing, climatic niche modeling, and demographic reconstruction, we sought to assess the risks and benefits of using translocations as a tool for recovery of endangered montane red fox (Vulpes vulpes) populations in the western United States. We demonstrated elevated inbreeding and homozygosity of deleterious alleles across all populations, but especially those isolated in the Cascade and Sierra Nevada ranges.
