Retroperitoneal Castleman’s disease: advocating a multidisciplinary approach for a rare clinical entity

BACKGROUND: Castleman’s disease is a rare and poorly understood disease entity that may resemble more common conditions and represents a clinical challenge to the treating surgeon. CASE PRESENTATION: In this report, we describe a case of a 61-year-old Caucasian woman with a symptomatic retroperitoneal mass. The specimen obtained from her resection contained a protuberant encapsulated mass, exhibiting microscopic features consistent with localized, unicentric Castleman’s disease. These characteristics included architectural features and immunohistochemical findings consistent with the hyaline vascular variant of Castleman’s disease. CONCLUSION: We report a very rare case of a retroperitoneal hyaline vascular type of Castleman’s disease. We discuss the diagnostic dilemma Castleman’s disease may present to the surgeon, with an emphasis on multidisciplinary management of these patients. We also review current data on pathogenesis, treatment and outcomes

Challenges Enrolling Children Into Traumatic Brain Injury Trials: An Observational Study

ObjectivesIn preparation for a clinical trial of therapeutic agents for children with moderate‐to‐severe blunt traumatic brain injuries (TBIs) in emergency departments (EDs), we conducted this feasibility study to (1) determine the number and clinical characteristics of eligible children, (2) determine the timing of patient and guardian arrival to the ED, and (3) describe the heterogeneity of TBIs on computed tomography (CT) scans.MethodsWe conducted a prospective observational study at 16 EDs of children ≤ 18 years of age presenting with blunt head trauma and Glasgow Coma Scale scores of 3–12. We documented the number of potentially eligible patients, timing of patient and guardian arrival, patient demographics and clinical characteristics, severity of injuries, and cranial CT findings.ResultsWe enrolled 295 eligible children at the 16 sites over 6 consecutive months. Cardiac arrest and nonsurvivable injuries were the most common characteristics that would exclude patients from a future trial. Most children arrived within 2 hours of injury, but most guardians did not arrive until 2–3 hours after the injury. There was a substantial range in types of TBIs, with subdural hemorrhages being the most common.ConclusionEnrolling children with moderate‐to‐severe TBI into time‐sensitive clinical trials will require large numbers of sites and meticulous preparation and coordination and will prove challenging to obtain informed consent given the timing of patient and guardian arrival. The Federal Exception from Informed Consent for Emergency Research will be an important consideration for enrolling these children.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135996/1/acem13085_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/135996/2/acem13085.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/135996/3/acem13085-sup-0001-DataSupplementS1.pd

Maintaining a Sufficient and Quality Physician Workforce: The Role of For-profit Medical Schools

Currently, in the United States there is a significant physician workforce shortage. This problem is likely to persist as there is no quick solution. The nature of this shortage is complex and involves factors such as an absolute physician shortage, as well as physician shortages in primary care and certain specialty care areas. In addition, there is a misdistribution of physicians to medically underserved areas and populations. The medical education system trains medical school graduates that eventually feed the physician workforce. However, several factors are in place which ultimately limits the effectiveness of this system in providing an appropriate workforce to meet the population demands. For-profit medical schools have been in existence in and around the continental US for many years and some authors have suggested that they may be a major contributor to the physician workforce shortage. There is currently one for-profit medical school in the US, however the majority exist in the Caribbean. The enrollment in and number of these schools have grown to partially meet the ever-growing demand for an increase in medical school graduates and they continue to provide a large number of graduates who return to the US for postgraduate medical training and, ultimately, increase the physician workforce. The question is whether this source will benefit the workforce quality and quantity needs of our growing and aging population
