Long-term Outcomes for Extraskeletal Myxoid Chondrosarcoma: A SEER Database Analysis.

Background: Extraskeletal myxoid chondrosarcoma (EMCS) is a rare tumor that typically has an indolent course but high rate of recurrence. We queried the Surveillance, Epidemiology, and End Results (SEER) database to assess factors associated with metastasis, treatment, and survival.

Methods: We queried the SEER 1973-2016 database for patients with myxoid chondrosarcoma (ICD-O-3: 9231/3).

Residents as Mentors: The Development of Resident Mentorship Milestones.

Background: Mentorship of residents by more senior colleagues has been identified as important for stress management and creating an ideal learning environment.

Objective: We set out to define the attributes of an ideal resident mentor and explore ways to develop these attributes during residency training.

Methods: A 28-member, multi-specialty counsel of residents and fellows used 2 phases of a small group exercise.

Catastrophic failure of an acetabular total hip arthroplasty component mimicking a posterior dislocation.

In our case study, we examine a case of catastrophic failure of a total hip arthroplasty acetabular component leading to complete central wear by the ceramic femoral head, requiring revision total hip arthroplasty. Despite subtle clinical findings, initial orthopaedic evaluation and treatment yielded a diagnosis of total hip arthroplasty dislocation. While a much more common phenomenon, the diagnosis led to futile initial attempts at closed reduction.

Patient-Centered Care and Population Health: Establishing Their Role in the Orthopaedic Practice.

As health care increasingly emphasizes high value, the terms "population health" and "patient-centered care" have become common, but their application is less clear. Patient-centered care encourages using data to optimize care for an individual. Population health offers a framework to consider how to efficiently and effectively manage a condition for a population, how prevention affects large groups, and the specific distribution of a given disorder.

Consensus on Graduate Medical Education Financing: An Analysis of Stakeholder Responses to the House Energy and Commerce Committee's Open Letter.

Background: In December 2014, the Energy and Commerce Committee of the US House of Representatives sent an open letter requesting interested parties to respond to 7 questions on graduate medical education (GME). More than 100 organizations and individuals responded.

Methods: An online search for responses yielded 27 organizations that had published their responses to the committee's open letter.

Targeted Chemotherapy in Bone and Soft-Tissue Sarcoma.

Historically surgical intervention has been the mainstay of therapy for bone and soft-tissue sarcomas, augmented with adjuvant radiation for local control. Although cytotoxic chemotherapy revolutionized the treatment of many sarcomas, classic treatment regimens are fraught with side effects while outcomes have plateaued. However, since the approval of imatinib in 2002, research into targeted chemotherapy has increased exponentially.

The attack rate of H1N1 in various berthing configurations on board an aircraft carrier.

Objective: We compared attack rates for novel H1N1 influenza A (H1N1) among various groups aboard an aircraft carrier as influenced by characteristics of their living arrangements.

Methods: During an outbreak of H1N1 on board the USS George Washington (GW), group affiliation (department or squadron membership) data were obtained on all patients who were placed in respiratory isolation based on their diagnosis with presumptive H1N1. Because berthing spaces are assigned by department and various characteristics of each department's berthing spaces are known, analysis of attack rates in comparison to these characteristics was possible.

Two aircraft carriers’ perspectives: a comparative of control measures in shipboard H1N1 outbreaks.

Background: The USS George Washington (GW) and the USS Ronald Reagan (RR), 2 US Navy aircraft carriers, experienced almost simultaneous outbreaks of novel H1N1 influenza A in the summer of 2009. We compared the respective epidemic control measures taken and subsequent lessons learned.

Methods: Data were collated from both outbreaks to assess various elements including attack rate, isolation/quarantine protocols, and treatment methods.

An institutional review of splenic artery aneurysm in childbearing-aged females and splenic artery aneurysm rupture during pregnancy. Is screening justified?

Objective: To determine the prevalence of splenic artery aneurysm (SAA) in women of childbearing age and the incidence of peripartum rupture to ascertain a possible benefit of screening this potentially high-risk population.

Methods: Patients diagnosed with SAA over a 6-year period were collected from a single institutional medical records database. Inclusion criteria included female gender and age between 15 and 49 years.
