Vibration exposure significantly alters mineral metabolism, with many patients showing elevated magnesium, zinc, cobalt, manganese, and plasma osmolality. These changes are likely secondary to other vibration-induced pathological effects.

Area of Science:

  • Occupational Health
  • Environmental Medicine
  • Biochemistry

Background:

  • Vibration disease is a condition linked to occupational exposure to vibrating tools.
  • Understanding the biochemical changes associated with vibration exposure is crucial for diagnosis and management.

Purpose of the Study:

  • To investigate plasma electrolytes, trace elements, and osmolality in patients with vibration disease.
  • To correlate these biochemical findings with specific tests indicative of vibration exposure.

Main Methods:

  • Studied 102 patients diagnosed with vibration disease.
  • Measured plasma levels of electrolytes and trace elements (sodium, potassium, calcium, magnesium, phosphorus, chloride, iron, copper, zinc, cobalt, manganese) and plasma osmolality.
  • Performed cold provocation tests, assessed vibration sense, thermoasymmetry, skin electric resistance, and hand/finger blood flow using Doppler-ultrasound sonometry.

Main Results:

  • Elevated magnesium (43%), zinc (45%), cobalt (57%), manganese (70%), and plasma osmolality (66%) were observed in a significant number of patients.
  • Specific tests indicated widespread pathological changes related to vibration exposure.

Conclusions:

  • Occupational vibration exposure appears to affect mineral metabolism.
  • Observed disturbances in mineral metabolism are likely secondary to broader pathological changes induced by vibration.
