Stress-related temporary hearing loss--evaluation of bio-humoral parameters: forensic and criminological applications.

The body-alarm reaction results from the activation of hypothalamic-pituitary-adrenal axis, which can lead to physio-psychological phenomena such as an exclusion/occlusion of the sense of hearing. One hypothesis to explain this alteration consists in a hydromechanical dysfunction of the internal ear attributable to antidiuretic hormone. In this study, we evaluated the perception of acoustic stimuli administered in stressful conditions in 14 phobic patients and in 20 healthy subjects, in order to assess the influence of stress on perceiving capabilities.

[Symptoms and musculo-skeletal changes among personnel of the State Police exposed to mechanical risk].

The aim of this present study was to inquire about spine morfo-functional alterations among policemen with jobs regarded as potentially hazardous, in order to identify preclinical alterations of column and to plan adequate preventive measures. A physiopathologic and working anamnesis was carried out by means of questionnaire about personal data, jobs, reported rachidian symptomatology and presence of orthopedic diseases, given to policemen on duty in Bari. Every chosen worker was subject to orthopedic and neurological examination, radiography of column, Formetric tridimensional examination, telethermography of spine.
