In thalassemia major or transfusion-dependent thalassemia patients, osteoporosis-related bone complications such as fracture events are common. However, no studies have investigated the risk of fracture in transfusion-naïve thalassemia population. Therefore, we conducted a longitudinal nationwide cohort study to determine whether this population has an increased risk of fracture. This nationwide, population-based cohort study analyzed data from 1998 to 2010 obtained from the Taiwanese National Health Insurance Research Database, with a follow-up period extending until the end of 2011...

Tracheobronchial injuries can be difficult to diagnose and manage, especially in the presence of polytrauma. A 50-year-old woman presented as a Level I trauma activation after being struck by a motor vehicle. Initial evaluation demonstrated intracranial hemorrhage and multiple chest injuries, including multilevel bilateral rib fractures, pneumomediastinum, and concern for tracheobronchial injury. After initial stabilization, bronchoscopy was performed and demonstrated an injury to the carina. We report a novel airway and ventilation strategy in the setting of concomitant tracheobronchial injury after severe blunt chest trauma in which extracorporeal support is contraindicated...

Diesel engines serve many purposes in modern oil and gas extraction activities. Diesel particulate matter (DPM) emitted from diesel engines is a complex aerosol that may cause adverse health effects depending on exposure dose and duration. This study reports on personal breathing zone (PBZ) and area measurements for DPM (expressed as elemental carbon) during oil and gas extraction operations including drilling, completions (which includes hydraulic fracturing) and servicing work. Researchers at the National Institute for Occupational Safety and Health (NIOSH) collected 104 full-shift air samples (49 PBZ and 55 area) in Colorado, North Dakota, Texas, and New Mexico during a four year period from 2008-2012 The arithmetic mean (AM) of the full shift TWA PBZ samples was 10 µg/m(3); measurements ranged from 0...

The OSHA final rule on respirable crystalline silica (RCS) will require hydraulic fracturing companies to implement engineering controls to limit workers' exposure to RCS. RCS is generated by pneumatic transfer of quartz-containing sand during hydraulic fracturing operations. Chronic inhalation of RCS can lead to serious disease, including silicosis and lung cancer. NIOSH research identified at least seven sources where RCS aerosols were generated at hydraulic fracturing sites. NIOSH researchers developed an engineering control to address one of the largest sources of RCS aerosol generation, RCS escaping from thief hatches on the top of sand movers...

The Late Pleistocene Shanidar 1 older adult male Neandertal is known for the crushing fracture of his left orbit with a probable reduction in vision, the loss of his right forearm and hand, and evidence of an abnormal gait, as well as probable diffuse idiopathic skeletal hyperostosis. He also exhibits advanced external auditory exostoses in his left auditory meatus and larger ones with complete bridging across the porus in the right meatus (both Grade 3). These growths indicate at least unilateral conductive hearing (CHL) loss, a serious sensory deprivation for a Pleistocene hunter-gatherer...

OBJECTIVES: Elderly patients represent the fastest growing and most difficult to treat population sustaining acetabular fractures. When treated surgically, isolated extrapelvic or combined intrapelvic-extrapelvic constructs may be used. No biomechanical or clinical study has compared the merits of these 2 techniques in cadaveric models. This research aims to biomechanically quantify the additional benefit of intrapelvic fixation to a standard extrapelvic fixation construct. METHODS: Ten cadaveric pelves underwent standardized anterior column and quadrilateral plate fracture creation...

Pediatric ankle fractures are common and have unique fracture characteristics because of the presence of distal tibial and fibular physes. When displaced (>3 mm widening of the physis or >2 mm intra-articular gap/step-off), these fractures are typically treated with anatomical reduction and internal fixation. Computed tomography is recommended for preoperative evaluation and surgical planning for intra-articular fractures. These fractures in younger children with substantial growth remaining should be followed closely to monitor for any growth disturbance...

Tibial fractures in children present a wide array of challenges to the managing orthopaedic surgeon. Injuries cover a spectrum from subtle tibial spine fractures to comminuted high-energy shaft fractures requiring free flap coverage. Significant risks range from malunion and leg length discrepancy to infected nonunions and Volkmann ischemic contracture. This article offers evidence and experience-based advice that is aimed at helping the community orthopaedic surgeon taking call.
