[A simplified occupational health and safety management system designed for small enterprises. Initial validation results].

Background: Occupational Health and Safety Management Systems (OHSMS) are known to be effective in improving safety at work. Unfortunately they are often too resource-heavy for small businesses.

Objectives: The aim of this project was to develop and test a simplified model of OHSMS suitable for small enterprises.

[Study on prevalence of upper and lower airways disorders in woodworkers, using data from medical surveillance reports and exposure registers].

Objectives: To evaluate correlations between exposure to wood dust, upper airways symptoms and lung function.

Methods: We have analysed medical surveillance reports of 197 woodworkers with a median wood dust TWA exposure of 2.1 mg/m3.

Arterial revascularization by laser angioplasty: first Italian experiences.

Eighty-seven laser angioplasty procedures were performed on 85 patients (73 men and 12 women). In the first phase (54 patients) a broad selection process included long occlusions (23.9 cm avg) and vessels with heavy calcification; in the second phase (31 patients) the authors treated vessels with shorter occlusions (10 cm avg) and less calcific.

[Arterial aneurysms of the upper limbs (our experience and review of the literature)].

The authors discuss about the very low incidence of the upper extremities aneurysms and about their post-traumatic etiology. They show their experience in 6 cases with a Follow up from 2 to 17 years. All the patients were operated on; in 2 cases the authors performed aneurysmectomy only and in 4 cases an axillo-brachial by-pass.

[Subclavian and innominate steal syndrome (our experience with 29 patients)].

Subclavian steal syndrome and innominate steal syndrome are well-known reasons of cerebral vascular insufficiency. Today this pathology can be corrected by extra-anatomic by-passes. In our experience in recent years (1980-1986) these by-pass (in our patients carotid-subclavian and subclavian-subclavian by-pass) gave very good outcomes.
