The authors followed up the health of 322 elementary-school pupils at Sabac who were exposed to increased air pollution with chemical agents (ammonia, fluor hydrogen, chloracetic acid, sulfur dioxide, soot). The mean annual concentration of these gases were above or insignificantly under maximally permitted values. The results of the examination were as follows: recurrent cough in 12.4 per cent of cases and clinical signs of chronic or obstructive bronchitis in 8.4 per cent of children. Values of vital capacity were under normal in 27.6 per cent of cases and almost in the half of children vital capacity was at the lower normal limit. FEV1/FVC was under normal in 15 per cent of cases and at the lower normal limit in about 18.6 per cent of children. In spite of a great number of children with positive cutaneous tests to inhalation allergens with Prick's method IgE was within normal limits in these children. Thus, a significant noxious effect of allergic components on respiratory organs should be excluded. This was also confirmed by spirometric measurements of the two subsequent maximal expiriums when differences of +/- 3% were registered. However, in children with allergic bronchitis the value dispersion was by 2-3 times greater. Consequently, the authors concluded that damaged respiratory organs in children at Sabac appeared in a greater number of cases than in other places and that these damages were due to increased concentrations of different chemical air pollution agents.

Two cases of varied forms of Aspergillosis are reported who were being diagnosed and treated on different lines. One case, who was treated on lines of allergic bronchitis, had very high total eosinophil count and, fleeting pulmonary infiltrates over a period of 5 years along with history of cough, fever and weight loss. Aspergillus fumigatus was grown on sputum culture. On the background of a long standing history of bronchial asthma with evidence of peripheral as well as central eosinophilia, fleeting pulmonary infiltrates and A. fumigatus grown on sputum culture, we kept the diagnosis of Allergic Bronchopulmonary aspergillosis (ABPA) and put the patient on steroids and Itraconazole. Patient showed good response to therapy. Another case, a 50 year old male, presented to us with clinical picture of subacute myelitis. Being a known case of ABPA and on steroid therapy for long duration, we kept the diagnosis of invasive aspergillosis. Growth of Aspergillus fumigatus on sputum culture on three occasions and MR imaging of spine further supported our view. Aspergillosis of the lung do not have characteristic clinico-radiological features of permit the diagnosis and should be considered in the differential diagnosis of tuberculosis, pneumonia, bronchiectasis, lung abscess and bronchial asthma.

In metalworking, the temperature of the cutting edge can reach 700 degrees C, which can adversely affect either the surface of the metal processed or the cutting edge itself. To reduce the heat and friction, the metalworking fluids and coolants are used. The most common are the oil-in-water emulsions, which are a mixture of concentrated mineral oils, different additives, and water. The presence of water and organic substrates generates conditions for microbial growth. Bacterial endotoxins can also be frequently detected in metalworking fluids. Rapid rotation of the metalworking tools makes various biological agents to be released as droplet bioaerosols that can be inhaled by the workers, thus producing adverse health effects, mainly on the respiratory system. More than 130 species of bacteria (including pathogens), moulds and yeasts have so far been found in the metalworking fluids and coolants. This paper summarizes the outcomes of projects on the impact of biological agents present in metalworking fluids. Exposure to oil mist, bacteria and endotoxins as well as the variety of health effects resulting from that exposure have been discussed. The findings indicate that the most frequent symptoms reported by the workers include cough with phlegm, wheezing breath, chest tightness and throat irritation. The most common among the diagnosed diseases are chronic allergic bronchitis, asthma, hypersensitivity pneumonitis and acute respiratory dysfunction indicated by decreased FEV1 values. The main skin diseases include oil acne, bacterial infections, dermatomycosis and allergic reactions. The review made the authors conclude that the problem of occupational exposure to biological agents released with coolants during metalworking has not been well recognized in Poland.
