Purpose: It is unclear whether computed tomography (CT) scans alter the surgical plan when ordered before surgery for fixation of intra-articular distal radius fractures (DRFs). The purpose of this study was to determine whether a preoperative CT scan alters the planned approach (PA) or planned fixation strategy (PFS) for open reduction internal fixation of intra-articular DRFs. Methods: Radiology records were retrospectively reviewed by one trauma surgeon and two hand surgeons for 33 intra-articular DRFs that met the inclusion criteria and previously underwent open reduction internal fixation. Surgeons were initially provided only preoperative radiographs; they were asked for their PA and …

BACKGROUND: Computational fluid dynamics has shown good agreement with contrast-enhanced magnetic resonance imaging measurements in cardiovascular disease applications. We have developed a biomechanical model of microvascular perfusion using contrast-enhanced magnetic resonance imaging signal intensities derived from skeletal calf muscles to study peripheral artery disease (PAD). METHODS AND RESULTS: The computational microvascular model was used to study skeletal calf muscle perfusion in 56 in-dividuals (36 patients with PAD, 20 matched controls). The recruited participants underwent contrast-enhanced magnetic resonance imaging and ankle-brachial index testing at rest and after 6-minute treadmill walking. We have determined associations of microvascular model parameters including the transfer …

Objective: To identify an age at which initiation of whole nut into the pediatric diet could be considered safe, by evaluating the age distribution of children undergoing bronchoscopy with removal of nut or seed material from the airway. Method: A retrospective chart review over a ten-year period identifying children age 0–18 that have undergone bronchoscopy with retrieval of airway foreign bodies. A statistical analysis of demographic data was carried out to identify age distribution of aspiration events. Results: Sixty-four cases of foreign body aspiration were identified, of which 43 (67%) were of organic origin, specifically nuts. A Fisher's exact test …
