title: Contribution to occupational angiopathy diagnosis using special examination method.
abstract: The authors presented 1642 cases of professional diseases caused by vibrations (VD) and 435 cases of extremity overload disease (EOD) diagnosed in the years 1974-1993. In addition to the standard rheoplethysmography there were evaluated the results of digital laser Doppler flowmetry (Moor instruments, UK) in 104 workers exposed to vibration (EV) and 25 controls with the age and smoking habit standardisation. In the selected subgroup were used continual measurements of digital blood pressure (Finapress, Ohmeda), digital LD flux and speed and the measuring of digital skin and central body temperature simultaneously. The records before and after 10 min of local cooling test (Rejsek method) and postocclusive hyperemic tests were summarized (computer evaluation, program STATGRAPHICS, T-test). Vasoconstriction to local cooling persisted in EV for longer time. The records of digital skin flux and speed, digital blood pressure reactions of EV were significantly different (EV/controls) also in the 10th min after cooling. Postocclusion hyperemic tests revealed good functional capacity also in EV. Advantages and disadvantages of methods were discussed. The results found by non-invasive methods in VD were in good relation to images obtained by means of radionuclides (clearance and cumulative tests). Cumulative tests (after 99m--pertechnetate i.v.) can be used in the selected differential diagnostic cases of angiopathies to help to distinguish degree of angiospastic and angioparalytic changes in the hands of VD, and also in special cases at angiopathies connected with EOD.
