Characteristics of Sports-Related Injuries Presenting to a Pediatric Emergency Department.

Objective: Pediatric injuries associated with participation in sports are common. Understanding the epidemiology and trends of sports-related injuries is an important component of injury prevention efforts and is the objective of this study.

Methods: A retrospective review of sports injuries presenting during the course of 1 year (2019) to the emergency department (ED) of Benjamin Russell Hospital for Children, a large academic children's hospital, was performed.

Primary pancreatic neuroblastoma presenting with opsoclonus-myoclonus syndrome.

Although neuroblastoma is a common solid organ malignancy in children, primary pancreatic neuroblastoma is a rare entity in children, with very few cases reported in the literature. The case discusses the presentation of a 21-month-old female presenting to the neurology clinic with ataxia and erratic eye movements. Our case illustrates the computed tomography, ultrasound, and scintigraphic findings of primary pancreatic neuroblastoma presenting as opsoclonus-myoclonus syndrome.

Hodgkin's and non-Hodgkin's lymphoma: spectrum of morphologic and immunophenotypic overlap.

Immunoperoxidase markers are useful and often essential in distinguishing among lymphocyte-predominant Hodgkin's lymphoma, T-cell-rich B-cell lymphoma, and lymphocyte-rich classic Hodgkin's lymphoma. However, it is becoming increasingly clear that these "entities" are closely related clonal B-lineage neoplasms that may intertransform and/or coexist. We hypothesized that, just as there are cases with morphologic overlap, there would also be immunophenotypic overlap that would be found when a series of such cases is studied in detail.
