RESUMO
BACKGROUND: The occupational exposure to urban pollution may induce adverse effects on the cardiovascular system. METHODS: Basal blood pressure, electrocardiogram (ECG) and the dynamic blood pressure monitoring during the work shift of 16 policemen (outdoors workers) and 16 administrative employees (indoor workers) were compared. RESULTS: The mean value of all the diastolic blood pressure surveys in policemen (84,53 ± 10,78) is significantly higher (p = 0,014) than the mean value of all the diastolic blood pressure surveys in indoor workers (82,74 ± 11.52). CONCLUSIONS: The results of our study suggest that the occupational exposure to urban stressors may induce an increase of the diastolic blood pressure in workers during the working hours.

The authors here describe, both macroscopically and microscopically, the case of a cellular schwannoma on the hand of a 66 year old man. The tumor had been present asymptomatically for about forty years and macroscopic examination showed it be a softly teseturs fibroma and to have slight transversal mobility. The histologic examination revealed dense tissue formed by elongated cells, which tended towards a layered formation. The mitoses were exceptional. There were also areas scattered with a large number of random vacuolated cells. There were no particular difficulties during the excision, and one year after surgery there was no apparent change or relapse.
