ABSTRACT
In the project of active research of occupational diseases was conducted a study on 45 welders in the engineering companies, with particular attention to the hazards of exposure to the optical radiation. The protocol used involved the execution of Breack Up test, Schirmer test, corneal staining and scraping cytology. It revealed that more than half of the welders had ocular lesions referable to their work activity as well as some permanent functional damages with the characters of dry eye syndrome. None of these diseases, which could alert for medical-legal and insurance, was highlighted by the occupational health physician.

We present an approach to assessing the impact of surveillance for surgical site infections and providing feedback to surgeons on their progress, as part of continuous quality improvement. Adjusting for patient risk factors using the Standardized Mortality Ratio, there was a marked decrease over time in both SMR (1.3 to 0.27) and crude infection rates (32 to 10 per thousand operations per year). These declines cannot be explained by decreased length of hospital stay.

The authors present a case of ileocecocolic intussusception by carcinoma of the caecum. They stress the most peculiar aspects of this condition: rare etiology; complete invagination of caecum appendix and ileum; typical clinical presentation characterized by variable dimensions of the mass and symptoms not ascribing to occlusion, no lesions at endoscopy; evidence of a typical "target mass" visualized at T.C.
