[Use of acupuncture in the treatment of hand ischemia caused by vibration].

An attempt of treatment of hand ischemia caused by vibration using acupuncture has been undertaken in forest workers occupationally exposed to mechanical vibration in the early phase of vascular lesions. The workers have been treated in the Kołobrzeg city sanatorium. The control groups consisted of forest workers of similar age and analogous vascular lesions treated in the sanatorium by balneologic methods (mineral salt bath, underwater whirlpool massage) or by pharmacologic agents (Pridazol, Bametan); some of subjects of control groups have been treated only by the climate therapy without other additives. It has been stated that acupuncture significantly ameliorates or even normalizes the peripheral ischemia of upper extremities induced by vibration, analogously or even better than balneologic therapy. The duration of amelioration period was longer in subjects treated by acupuncture than in those treated with balneologic methods. In contrast, the pharmacologic treatment or the climate therapy remained without effects. The acupuncture therapy is cheaper than balneotherapy and could be used by trained industrial physicians in conditions o outpatient care. However, there is a need for further studies on detailed conditions of acupuncture therapy.

Balneoclimatic prevention and treatment of vascular disorders due to vibration at the forestry workers.

A total of 824 chain-saw operators who were employed in felling trees in the forestry industry were exposed to local vibration, which produced peripheral blood-flow disorders and lesions in the joints and hand bones. In the last 10 years, they have undergone 24-day balneoclimatic treatment at the Kołobrzeg Health Resort. It was found that a stay in the spa and certain balneological treatments exert a favorable effect on the peripheral blood-flow disorders produced by the local vibration of chain saws. The symptoms (chills and numbing of the fingers, etc.) disappeared in nearly 40% of these workers. An improvement in the objective indices of the peripheral circulation (thermographic and plethysmographic tests) was observed in about 90% of patients treated with brine baths combined with underwater vibratory massage (rotatory) or brine baths alone. The brine bath and vibratory massage have a direct beneficial influence on the peripheral blood flow of pectoral limbs.

[Social and occupational adaptation of young workers in a workshop].

The young workers adaptation to the workplace depends on a number of psycho-social and professional factors, such as: competences, qualifications, personality, attitude to work, attitude to superiors and co-workers in a social group etc. Furthermore, the psycho-social adaptation depends on the style of life led so far and the impact of the family- and school milieu. The professional adaptation begins when one chooses his future profession. However, it is not easy to choose a profession that would give satisfaction and meet young people's ambitions. A considerable assistance in this area comes from vocational guidance dispensaries and health service, especially for young people suffering from psychophysical defects. In the initial period of professional work it becomes essential to ensure that the young worker is well informed on his workplace, range of duties and all relevant problems inherent in the workplace as well as some guidance as regards possible promotion and improvement of qualifications, and the use of all possible social allowances. A young worker should not in any way feel isolated in his workplace. The person who imparts all the information should not only be a good expert and production organizer, but a good educator as well.

Adaptation, Psychological

[Role of occupational medicine in ergonomic activity].

Occupational medicine, and physiology of work and occupational hygiene in particular, play an important and inspiring role in ergonomic activity. In the process of adaptation of work or technique to man, the knowledge about man demarcates the lines and the scope of activities as well as helps to evaluate the effectiveness of ergonomic solutions. That is of particular importance in the area of the so called "products of ergonomics", at evaluation of adaptation of man to equipment and appliances of daily use. Therefore it may be assumed that occupational medicine-beside psychology-determines, among others, the degree of adaptation of production process to psychophysical capabilities of man and establishes the most important lines of activities aimed at improvement of this adaptation: whereas technique and production organization fulfills an important and difficult executive role in implementation of these designs. Both lines of activities i.e. indicating the direction of the changes and their implementation are equally valid and closely interrelated, as only joint complex action may bring the expected results.

Cybernetics

[Statics of complete prostheses. 1].

The author discusses the principles of arrangement of artificial teeth in complete prostheses from the standpoint of statics. In the consideration of the action of forces released in the mastication the values of these forces, the application points, the directions of action and vector sense as well as the developing torques are taken into account.

Dental Occlusion

[Statics of complete prostheses. 2].

The statics of prostheses in complete absence of teeth is discussed with analysis of the effect of the position of the masticating surfaces of artificial teeth on the values of forces disturbing the balance of the prosthesis during mastication. Considering the friction forces active during mastication, the worse fixation of lower prostheses, and the lateral position of the mandible in relation to the maxilla the author describes as optimal such a spatial arrangement of artificial teeth that in centric occlusion the interalveolar line passes through the centre of their masticating surfaces which are perpendicular to it.
