Relief of Sitting Pain by Resecting Posterior Femoral Cutaneous Nerve, and Elucidation of Its Anatomical Branching Pattern.

Background:  Injury to the posterior femoral cutaneous nerve (PFCN) produces sitting pain in the buttock, posterior thigh, and/or the ischial tuberosity. The anatomy of the PFCN has not been well described, and just one small cohort of patients has been reported to have resection of the PFCN.

Methods:  Retrospective review of all patients undergoing resection of the PFCN for sitting pain by the senior author between 2012 and 2019 was performed.

Noninvasive Management of Pediatric Isolated, Condylar Fractures: Less Is More?

Background: The purpose of this study was to examine injury patterns in pediatric mandibular condylar fractures and to propose and evaluate the validity of an institutional treatment algorithm for such fractures.

Methods: A retrospective chart review was conducted on pediatric patients who presented to the authors' institution with isolated mandibular condylar fractures between 1990 and 2016. Patients were categorized by dentition, and information regarding demographics, injury characteristics, management, and complications was compiled.

A Two-step Technique for Neo-umbilicoplasty in the Abdominal Reconstructive Population.

The umbilicus is the centerpiece of the abdomen and an important cosmetic landmark. Secondary intention healing can be used to create the illusion of an umbilicus in reconstructive surgery. However, there is a sparsity of literature on the role of neo-umbilicoplasty in this subset of patients and how they perceive their new umbilicus.

Computer-Assisted Design and Manufacturing Assists Less Experienced Surgeons in Achieving Equivalent Outcomes in Cranial Vault Reconstruction.

Purpose: The purpose of this study was to assess whether long-term outcomes were equivalent between computer-assisted design and manufacturing (CAD/CAM) -assisted cranial vault reconstruction performed by an inexperienced surgeon, with fewer years of surgical experience, and traditional reconstruction performed by senior surgeons with many decades of experience.

Methods: An Institutional Review Board-approved retrospective cohort study was performed for all patients with nonsyndromic craniosynostosis between the ages of 1 month to 18 years who received primary, open calvarial vault reconstruction at the Johns Hopkins Hospital between 1990 and 2017. The primary outcome variable was the Whitaker category (I-IV) for level of required revision at the 2-year follow-up visit.

Heparin-Conjugated Decellularized Bone Particles Promote Enhanced Osteogenic Signaling of PDGF-BB to Adipose-Derived Stem Cells in Tissue Engineered Bone Grafts.

Adipose-derived stem cells (ASCs) are a promising cell source for regenerating critical-sized craniofacial bone defects, but their clinical use is limited due to the supraphysiological levels of bone morphogenetic protein-2 required to induce bone formation in large grafts. It has been recently reported that platelet-derived growth factor-BB (PDGF) directly enhances the osteogenesis of ASCs when applied at physiological concentrations. In this study, a biomimetic delivery system that tethers PDGF to decellularized bone matrix (DCB) is developed to enhance osteogenic signaling in bone grafts by colocalizing PDGF-extracellular matrix cues.

Association of a Simulated Institutional Gender Equity Initiative With Gender-Based Disparities in Medical School Faculty Salaries and Promotions.

Importance: Despite progress in narrowing gender-based salary gaps, notable disparities persist in the scientific community. The significance of pay difference may be underestimated, with little data evaluating its effect on lifetime wealth after accounting for factors like time to promotion and savings.

Objectives: To characterize gender disparities in salary and assess the outcomes associated with a gender equity initiative (GEI).

Utilization of Microdissected Thin Perforator Flap Technique in the Treatment of Bulky and Deformed Skin Flaps.

Background: This study investigates the feasibility and clinical impact of the microdissected thin perforator skin flap strategy on bulky and deformed skin flaps during second-stage revision surgery.

Methods: Seventeen patients were selected and underwent the microdissected thin perforator skin flap technique to treat bulky and deformed skin flaps after free flap reconstruction between October 2013 and October 2015. Perforator vessels were isolated and protected under a microscope.

When policy gets it right: variability in u.s. Hospitals' diagnosis of ventilator-associated pneumonia*.

Objective: The Centers for Disease Control has recently proposed a major change in how ventilator-associated pneumonia is defined. This has profound implications for public reporting, reimbursement, and accountability measures for ICUs. We sought to provide evidence for or against this change by quantifying limitations of the national definition of ventilator-associated pneumonia that was in place until January 2013, particularly with regard to comparisons between, and ranking of, hospitals and ICUs.
