RESUMO
We carried out an audiological survey of 204 officers at an infantry regiment in southern Sweden. The officers were exposed to impulse noise from firearms with peak levels up to 185 dB (SPL). The audiological measurement results were summarized in four age-groups, all of which showed significant hearing loss compared to ISO 1999 (1990) database A of a non-noise-exposed male population. Even officers who claimed regular use of hearing protectors during their entire military career showed these significant hearing losses. In the survey we also studied the association of the hearing thresholds with subjective exposure to heavy detonations and the annoyance of tinnitus. We found a significant relation between exposure to heavy detonations and tinnitus.

A case of recurrent pulmonary embolism, secondary to thrombosis in an aneurysm of the popliteal vein is described. The source of embolism was not obvious clinically, and it was discovered only after venography. The anomaly was amenable to surgical intervention and the patient was cured from his source of embolism. We have found only one similar case in the literature.
