Blood lead levels in children of S.W. Sardinia.

The purpose of the present study was to make a preliminary evaluation of blood lead levels in school-aged children from three towns of southwestern Sardinia, Portoscuso, S. Antioco and Calasetta, the first of which is very close to a large industrial complex. Blood lead concentration was determined in venous blood samples by graphite furnace atomic absorption spectrophotometry. The survey revealed that children residing in the town of Portoscuso had higher mean blood lead levels (12.7 micrograms/dl) than children of the same age residing in S. Antioco and Calasetta (8.3 and 8.4 micrograms/dl respectively) and that levels were slightly higher in males than in females. This difference is suggested to be a result of the greater fallout of industrial pollutants in the area of Portoscuso.

Fungal air-borne spores as health risk factors among workers in alimentary industries.

A survey to evaluate the occurrence of air-borne fungal spores in two different food industries, dairies and bakeries, was conducted. Our data revealed considerable fungal pollution in the environments of both industries, as well as some differences in the distribution of the genera of fungi recovered. Noteworthy was the frequent finding of numerous fungi frequently responsible for allergic rhinitis, asthma and other diseases, or well-known for their production of mycotoxins in foods or characterized by their degradative activity against various substances. Aspergillus, Candida, Fusarium, Geotrichum, Mucor and Penicillium were the most common genera identified in dairies while Alternaria, Aspergillus, Botrytis, Candida, Cladosporium, Penicillium and Saccharomyces occurred more frequently in bakeries. The survey showed that fungi can play a significant role in allergic and non-allergic diseases in modern working environments.

Multicentre clinical and bacteriological study of sulbenicillin in patients with bronchopulmonary infection.

In view of the pharmacodynamic and therapeutic properties of a broad-spectrum semisynthetic penicillin recently introduced in Italy, namely sulbenicillin, the authors conducted a multicentre clinical and bacteriological trial of the drug administered by intramuscular or intravenous injection in daily doses of 4, 6 or 8 g given in two or three administrations daily to a group of 66 patients with acute bronchopulmonary infection, mainly exacerbation of chronic infection, hospitalized in four Pneumology Centres of Sardinia. The authors assessed clinical, radiological, microbiological, and biohumoral parameters before and after treatment to provide a basis for assessing test product effectiveness and tolerability. On the strength of their findings, the authors concluded that the clinical and bacteriological activity of sulbenicillin was satisfactory and its local and general tolerability was excellent. The assembled findings indicate that the new antibiotic molecule can be used to advantage in the treatment of nontubercular bronchopulmonary infections, including severe or otherwise "difficult" cases, providing that the drug is administered at adequate dosages and for sufficiently long treatment periods.
