Research Letter: Rate of BPPV in Patients Diagnosed With Concussion.

Objective: The purpose of this study was to investigate the incidence of benign paroxysmal positional vertigo (BPPV) specifically among patients with dizziness in the rehabilitation phase of concussion recovery and to provide evidence regarding the importance of BPPV assessment in physical therapy concussion evaluations.

Setting: Outpatient neurologic rehabilitation center at a suburban comprehensive rehabilitation hospital.

Participants: Fifty patients diagnosed with concussion and referred to vestibular physical therapy with complaints of dizziness were tested for BPPV within their first 3 visits.

The Relationship Between Body Mass Index and Fluoroscopy Time During Intraarticular Hip Injection: A Multicenter Cohort Study.

Background: Higher body mass index (BMI) is associated with difficulty in obtaining imaging studies. While there is a small body of literature regarding the relationship between fluoroscopy time and BMI during injections for pain management, this has not been studied for intraarticular (IA) hip injections. Further, in academic training centers, trainee involvement may affect this relationship.

MRI and Motor Outcomes in Children with Cerebral Palsy.

Investigators from University of Melbourne, Monash Children's Hospital, Royal Children's Hospital & Murdoch Children's Research Institute sought to identify correlation between magnetic resonance imaging (MRI) characteristics including white matter injury (WMI) in children with cerebral palsy (CP) and severity in motor outcomes later in life, irrespective of CP subtype.

Anterior thoracic surgical approaches in the treatment of spinal infections and neoplasms.

Background: Thoracic surgeons are commonly consulted to provide anterior thoracic exposure for infection and malignant neoplasms involving the thoracolumbar spine. These cases can present significant technical and management challenges secondary to the underlying pathology, associated anatomic inflammation, and impaired functional status. In this study, we review the perioperative outcomes in patients undergoing anterior spinal exposure for infection and neoplasm.

Physical activity of adult female rhesus monkeys (Macaca mulatta) across the menstrual cycle.

Physical activity is an important physiological variable impacting on a number of systems in the body. In rodents and several species of domestic animals, levels of physical activity have been reported to vary across the estrous cycle; however, it is unclear whether such changes in activity occur in women and other primates across the menstrual cycle. To determine whether significant changes in activity occur over the menstrual cycle, we continuously measured physical activity in seven adult female rhesus monkeys by accelerometry over the course of one menstrual cycle.
