INTRODUCTION Total intravenous anesthesia with propofol and a synthetic opioid is a frequently chosen anesthetic technique for posterior spinal fusion. Despite its utility, adverse effects may occur with high or prolonged propofol dosing regimens including delayed awakening. The current study investigated the propofol-sparing effects of the concomitant(More)
The pediatric triplane ankle fracture represents a unique spectrum of injury that does not fit neatly into the Salter-Harris classification of physeal injury. This fracture is particular to the pediatric population and often is termed a transitional injury. It is the result of the characteristic asymmetric closure of the distal tibial physis over a period(More)
One third of patients with achondroplasia develop spinal stenosis requiring surgical intervention. However, this condition rarely develops before the age of 15 years. The goal of the current study was to identify anatomical factors and clinical symptoms associated with early presentation of lumbar stenosis in such patients. The charts of 22 pediatric(More)
BACKGROUND Dexmedetomidine may be a useful agent as an adjunct to an opioid-propofol total intravenous anesthesia (TIVA) technique during posterior spinal fusion (PSF) surgery. There are limited data regarding its effects on somatosensory (SSEPs) and motor evoked potentials (MEPs). METHODS The data presented represent a retrospective review of(More)
BACKGROUND Spinal stenosis is a common complication of achondroplasia. To our knowledge, no study has evaluated a greater than 2-year outcome after surgical intervention for spinal stenosis in such children or compared decompression with and without instrumentation in relation to revision surgery. Our purpose was to assess the efficacy of lumbar(More)
The G1691A (Leiden) mutation of the factor V gene is the most prevalent identified cause of venous thrombosis. Therefore, we developed a new genetic test using the TaqMan system. With this assay which combines PCR amplification and detection reaction in one closed tube, a cohort of 234 patients with a history of thrombosis was screened. In parallel,(More)
Acute compartment syndrome is a surgical emergency requiring immediate intervention to limit tissue and nerve injury. Although the measurement of compartment pressure is frequently performed, there is controversy regarding the pressure at which fasciotomy should be performed. Near-infrared spectroscopy (NIRS) uses the same technology as pulse oximetry to(More)
Peripheral blood samples (n= 1240), obtained at variable intervals from 483 heart transplantation (HTx patients under immunosuppressive therapy, and blood samples (n=1013) obtained upon blood donation from 1013 healthy anti-human cytomegalovirus (HCMV) positive blood donors, were tested for HCMV DNA by nested polymerase chain reaction (PCR). The detection(More)
A delayed spinal epidural hematoma following scoliosis surgery is relatively uncommon but well recognized by clinical and radiographic findings. A 12-year-old girl with scoliosis measuring 80 degrees lower thoracic curve underwent anterior (T6-T12) and posterior fusion with posterior instrumentation from T2 to L1. She developed bilateral leg weakness and(More)
