Delayed Diagnosis of Pharyngeal Perforation following Exploding Tyre Blast Barotrauma
Introduction. Pharyngoesophageal perforation secondary to barotrauma is a rare phenomenon that can have serious complications if identified late. It is challenging to detect due to nonspecific symptoms. We present a case in which detection proved difficult leading to delayed diagnosis. Case Report. A 27-year-old mechanic presented with haemoptysis, dysphonia, and odynophagia after a car tyre ex...
متن کاملSurgery of violence. IV. Blast injuries of the ear.
The shock front of a blast wave is irregular and can be deflected by obstacles in its pathway, depending on their size and position. Consequently, the injurious effects of blast tend to be capricious, and one person may be unharmed while those around him are killed or severely injured. In most explosions solid material is changed suddenly into a gas with an enormous increase in volume and thus ...
متن کاملEffects of blast overpressure on the ear: case reports.
The case histories of five patients who experienced blast overpressure in excess of 200-dB peak pressure level are presented. Despite the significance of the sound pressure levels received in a military training accident and the severe injuries that resulted from the blast, these individuals experienced substantial improvement of hearing 1 year later. Undoubtedly, successful surgical interventi...
متن کاملMechanisms of Hearing Loss after Blast Injury to the Ear
Given the frequent use of improvised explosive devices (IEDs) around the world, the study of traumatic blast injuries is of increasing interest. The ear is the most common organ affected by blast injury because it is the body's most sensitive pressure transducer. We fabricated a blast chamber to re-create blast profiles similar to that of IEDs and used it to develop a reproducible mouse model t...
متن کاملEigenfrequencies of Fractal Drums Eigenfrequencies of Fractal Drums
A method for the computation of eigenfrequencies and eigenmodes of fractal drums is presented. The approach involves first mapping the unit disk to a polygon approximating the fractal and then solving a weighted eigenvalue problem on the unit disk by a spectral collocation method. The numerical computation of the complicated conformal mapping was made feasible by the use of the fast multipole m...
