Low-Cost Earmuff Shown to Significantly Reduce Cast-Saw Noise.

Hearing protection devices reduce cast-saw noise. It would be helpful to identify the devices that are both effective and economical. Prior studies have shown that expensive noise-reduction headphones significantly reduced the anxiety associated with cast removal with a powered oscillating saw.

Orthopedic Surgical Helmet Systems Significantly Impair Speech Intelligibility.

Surgical suits provide protection to orthopedic surgeons, but the suits and fan noise may interfere with communication between operative team members. The goal of this study was to quantify the fan sound and effect of the suit, fan, and N95 mask. Sound levels were measured using a specialized manikin and evaluated using preferred speech interference levels (PSILs), noise criterion (NC) ratings, and comparison with speech sound levels from the literature.

Multicentric Reticulohistiocytosis: Elective Excision of Symptomatic Hand Nodules With 1-Year Follow-Up.

Multicentric reticulohistiocytosis is a rare non-Langerhans cell histiocytic rheumatologic disorder characterized by multiple skin lesions, painful hand nodules, and destructive polyarthritis that results in arthritis mutilans in 20% to 30% of patients. In the current literature, there have been approximately 300 cases reported and the pathogenesis remains unclear. Currently, there is no diagnostic serologic test and no consensus on management.
