Evaluating the potential impact of ototoxicant exposure on worker health.

Occupational exposure to ototoxicants, substances that can cause hearing loss alone or exacerbate hearing loss when exposure occurs in combination with noise, is a workplace hazard that is poorly understood. A review of existing research indicates that some solvents and heavy metals may be ototoxic, but few studies have attempted to estimate the impact of ototoxicant exposure on the United States worker population. Researchers examined trends in workplace exposure to ototoxicants among workers in the United States by comparing exposure data collected by the Occupational Safety and Health Administration against worker hearing loss data provided by the Bureau of Labor Statistics (BLS) for 2012-2019.

Ponseti Casting vs. Soft Tissue Release for the Initial Treatment of Non-idiopathic Clubfoot.

Ponseti casting has universally been accepted as the gold standard for treatment of idiopathic clubfoot. Conversely, primary treatment for non-idiopathic clubfoot has not been established. The purpose of this study is to compare treatment outcomes following primary soft tissue release (STR) and Ponseti casting of non-idiopathic clubfoot.

Preoperative Angiography Can Guide Treatment of Post-Femoral Neck Fracture Capital Femoral Physeal Separation and Displacement: A Case Report.

Case: A 13-year, 6-month-old boy sustained a Delbet type III femoral neck fracture with postoperative femoral head avascular necrosis (AVN) and subsequent capital femoral physeal separation (CFPS). Preoperative angiography revealed a patent artery of the ligamentum teres to the femoral head epiphysis, allowing our patient to undergo a modified Dunn procedure to maintain this artery and preserve his native hip.

Conclusion: Preoperative angiography allows for real-time identification of femoral head epiphyseal blood supply in patients with femoral head AVN complicated by CFPS and guides surgical treatment for hip preservation.
