Introduction. Syndrome of Colinet-Caplan is a relatively rare occupational disease. In the present structure of occupational diseases in Ukraine and abroad it is recorded in single cases. In such type of pathology such syndrome is recorded as pneumoconiosis combined with arthritis, which by its clinical and radiographic characteristics does not differ from rheumatoid one.
The purpose of the stud. – to analyse the clinical case of Colinet-Caplan’s occupational syndrome, having been diagnosed in the Clinic for occupational diseases of the "Institute for occupational health of NAMS of Ukraine".
Materials and methods. A medical history of the patient "R", results of clinical, radiological, laboratory and functional examinations.
Results. The level of risks of occupational pathology at enterprises, where silica dust exceeds the maximum allowable concentration, continues to stay high. Even very effective engineering tools systems for dust control do not provide the decreasing dust concentrations in the working zone, leads to development of occupational pathology in the respiratory system, including pneumoconiosis and Colinet- Caplan’s syndrome. The examined patient was R. of 56 years old, work experience of about 30 years in exposure to dust with silica content of 10–70 % in concentrations, exceeding maximum permissible levels. The established diagnosis: Colinet-Caplan’s (q/q, 2/2) syndrome, rheumatoid arthritis: deforming arthrosis of the interphalangeal, metacarpophalangeal, intercarpal joints, and the left wrist joint of the 1st degree, the right wrist joint of the 2nd degree as well as pulmonary insufficiency of the 1st degree of the restrictive type. The diagnosis was confirmed by physical examination, results of clinical laboratory studies, x-ray exams, and the data of the patient’s work conditions.
Conclusions. The most important task of occupational health care is prevention of occupational and occupation-related diseases. Preventive medical examinations are important for detecting diseases at early stages. The effective therapy prevents the progression of the disease, development of complications, make it possible to maintain the ability to work and quality of workers’ life.
