[The surveillance of occupational risks. Problems and perspectives of the recent legislative framework after the national preliminary survey]. / I dati sanitari aggregati e di rischio dei lavoratori sottoposti a sorveglianza sanitaria. Risultati preliminari dello studio pilota nazionale sulle comunicazioni ex art. 40. D.lgs 81/2008.

BACKGROUND: Legislation in Italy concerning health, safety and prevention at the workplace recently established a new data communication standard OBJECTIVES: The findings are reported of a specific survey on 18 Local Health Units (ASL) over the entire Italian territory, aimed at identifying the critical points in data management and analyze the available information. METHODS: The occupational health physician for each company must collect and transmit information on the number of workers submitted to health surveillance protocols to the Local Health Unit. Information must be divided by risk factor and gender Local health Units then transmit the data to the Regions and finally to the Italian National Institute for Occupational Safety and Prevention (ISPESL). RESULTS: A sample of 22.977 companies was studied, providing information on about 410,009 workers undergoing health surveillance protocols. Carrying or moving heavy loads, exposure to noise, VDU and chemical substances were the most frequent risk factors. The difference between genders was significant in risk allocation, with exposures to VDU and biological agents prevalently among females. CONCLUSIONS: The information thus collected suffered from a lack of data organization and completeness in the sample under study, but nevertheless provides preliminary evidence of a map of occupational risks on a national basis, confirming the potential for the new law (D.Lgs 81/2008) to investigate health safety and prevention at the workplace.

[Dynamic electrocardiographic study of a group of urban bus drivers]. / Studio elettrocardiografico dinamico su un gruppo di conducenti di autobus urbani.

On the initiative of Preventive Medicine promoted by the Genoa Urban Transport Company, authors carried out an inquiry of dynamic electrocardiography by Holter during the normal working activity of a group of 95 drivers. It was observed mean value of heart rate of 86.23 +/- 10.08; moreover patients with more working seniority shown a lesser increase of the pulse rate with statistical difference as compared with other groups. In any case we don't observe any change of ventricular repolarization.
