[Use of functional telethermography in the diagnosis of some occupational diseases (due to vibrating tools; carbon disulfide; polyvinyl chloride].

: The AA. have considered occupational technopathies due to vibrating tools, carbon disulphide and polyvinyl chloride. The functional or organic involvement in the peripheric vascular system, attributable to the disease, has been evaluated by thermographic examinations, carried out in 35 patients, in basal conditions and, when possible, after cold-test. The results have demonstrated that functional thermography may be a reliable tool both in the early diagnosis and in the prognosis of occupational vascular diseases, especially when it can replace more traumatic methods (such as angiography) in the periodic controls: in fact, it can be sufficient to carry out a simple thermoscopy and to compare the result with the previous photo-thermogram.
