[Amalgam: yesterday and today].

Recently some reports claim that mercury released from amalgam fillings cause adverse effect to the patient. Mercurial toxicity is a risk for dental personnel but it is completely preventable by using proper mercury hygiene. From the side of the patients, amount of mercury released from amalgam fillings is far to cause any adverse effect. The claims don't have scientific support. Hypersensitivity reactions to amalgam fillings are exceedingly rare. There is no alternative to dental amalgam in the posterior region and routine use of composite as an amalgam substitute can not be endorsed. Besides, when considered improved corrosion resistance and marginal endurance with high-copper types, amalgam is an effective and useful material.

[Back ache in helicopter pilots].

Due to low back pain (LBP) and harmful effects of flying, questionnaires were sent to 71 helicopter pilots of the experimental group, 22 mechanics helicopter flyers and to the control group of 28 air-traffic controllers. The prevalence of LBP was the highest in helicopter pilots, then in helicomechanics and air-traffic controllers (53%, 50% and 36%). Effects of exposure to vibration, body posture and working load have not contributed significantly to the occurrence of LBP. LBP has not lead to an important difference in the strength of the back musculature, body mass index and spondylosis, that is, scoliosis. The necessity of further study of LBP and maintaining of specific preventive measures are indicated.

[Verification of vital capacity and 1 second forced expiratory volume values in 14,234 candidates for aviation school].

The values of vital capacity (VC), forced expiratory volume in the first second (FEV1) and Tiffeneau index (100xFEV1/VC) were determined in 14,234 examinees in the period 1977-1987. Examinations were performed using the Godart expirometer. After the statistical analysis of the results being performed, the unique table was made according to height and age of examinees. The examinees came from all regions of Yugoslavia. The results of the study can be used for establishment of standard values of pulmonary ventilation for candidates for aviation schools, i.e. for youngsters aging from 14 to 20 years.
