To determine the effect of embolization with absorbable gelatin sponge slurry on the incidence of pneumothorax (PTX) and need for chest tube placement after percutaneous lung biopsy. Seven hundred fifty-two percutaneous lung biopsy procedures and fiducial seed placements were performed using computed tomography (CT)-guidance at a single institution. A(More)
A case of acute subdural hemorrhage caused by rupture of an anterior communicating artery aneurysm is presented. The patient is a young man who presented with an acute onset of neurologic symptoms; computed tomography revealed subdural hemorrhage in the absence of associated subarachnoid or intraparenchymal bleeding.
BACKGROUND There is increasing evidence that donor-specific anti-HLA antibodies (DSA) are associated with poor outcomes after cardiac transplantation in adults, but data are limited in children. The objective of this study was to examine the development and consequences of de novo DSA in pediatric recipients of heart transplants. METHODS We analyzed 105(More)
Study Design Retrospective cohort study. Objective To determine the short-term outcomes of two different lateral approaches to the lumbar spine. Methods This was a retrospective review performed with four fellowship-trained spine surgeons from a single institution. Two different approach techniques were identified. (1) Traditional transpsoas (TP) approach:(More)
BACKGROUND Past series have identified completion pneumonectomy (CP) as a high-risk operation. We evaluated factors affecting outcomes of CP with a selective approach to offering this operation. METHODS We analyzed a prospective institutional database and abstracted information on patients undergoing pneumonectomy. Patients undergoing CP were compared(More)
KEY POINTS Inositol-1,4,5-trisphosphate receptors (IP3 Rs) modulate pacemaking in embryonic heart, but their role in adult sinoatrial node (SAN) pacemaking is uncertain. We found that stimulation of IP3 Rs accelerates spontaneous pacing rate in isolated mouse SAN cells, whereas inhibition of IP3 Rs slows pacing. In atrial-specific sodium-calcium exchanger(More)
There is a wide array of device modalities available for post-operative treatment following arthroscopic knee surgery; however, it remains unclear which types and duration of modality are the most effective. This systematic review aimed to investigate the efficacy of device modalities used following arthroscopic knee surgery. A systematic search of the(More)
BACKGROUND Identification of biomechanical risk factors associated with anterior cruciate ligament (ACL) injury can facilitate injury prevention. The purpose of this study is to investigate the effects of three foot landing positions, "toe-in", "toe-out" and "neutral", on biomechanical risk factors for ACL injury in males and females. The authors(More)
PURPOSE To apply and monitor a single institution's adherence to internally established guidelines for the preoperative administration of platelets and/or fresh frozen plasma (FFP) before a specified subset of minimally invasive interventional radiology (IR) procedures. MATERIALS AND METHODS Beginning in December 2008, we implemented a set of restrictive(More)
INTRODUCTION Cost containment and surgical inefficiencies are major concerns for hospitals in this era of declining resources. The primary aim of this investigation was to understand subjective perceptions of perioperative spine surgical quality across three practice settings and to identify potential factors contributing to these perceptions. Subsequently,(More)
