Acoustic Trauma-Clinical Presentation

Magnesium therapy in acoustic trauma.

Acoustic trauma is one of the major causes of hearing loss and tinnitus, particularly in industrial environments. Noise-induced hearing loss (NIHL) results in direct mechanical damage as well as in indirect metabolic processes. Metabolic disorders have multiple origins: ionic, ischemic, excitotoxic and production of cochlear free radicals causing cell death, due to necrosis or apoptosis. The ef...

Unusual Presentation of Pulmonary Hematoma after Blunt Chest Wall Trauma

A 25-year-old man was admitted in hospital due to right side hemopneumothorax secondary to car accident. A chest tube was inserted. During the hospitalization days, chest CT scan revealed a 3cmx3 cm oval-shaped density located in the right upper lobe. Since he was in a good general condition, he was discharged from hospital after removal of chest tube and a follow-up chest CT-scan was recommend...

Neurofibroma: Report of a rare clinical presentation

Neurofibroma is a tumor composed of a complex proliferation of neuromesenchymal tissue (Schwann cells, perineural cells, fibroblast, and mast cells). We report a 45-year-old female who had a slow growing, large, soft, pedunculated mass on her left lateral neck. A skin biopsy confirmed the diagnosis of neurofibroma.

Protecting the Inner Ear from Acoustic Trauma.

Calcium activated proteases, or calpains, play an important role in neurodegeneration. In some cases, neural degeneration can be significantly reduced by leupeptin, a potent calpain inhibitor. To determine if leupeptin could protect against noise-induced hearing loss and hair cell loss, we infused leupeptin into scala tympani of one cochlea before, during and after a 14-day exposure to a 100 dB...
