Feasibility study for interspecialistic collaboration in active research of urothelial neoplasms of professional origin.

Introduction: In Italy only a small fraction of cancer is reported to the supervisory body and recognised as professional by the insurance institution. Among the causes of this sub-notification, especially for lowgrade etiologic fractional cancers such as bladder cancers are the lack of knowledge of carcinogenicity in the occupational field and the consequent incomplete medical history collections.

Objectives: Diagnosis of occupational bladder neoplasms and activation of systematic surveillance of tumors of professional origin through an "active research" program.

Upper airway and eye involvement in polyurethane shoe sole production workers.

Objectives: This cross-sectional study was aimed to investigate the prevalence of work-related upper and lower airway and eye symptoms in 118 workers in polyurethane shoe soles (PSS) production.

Methods: Workplace monitoring of methylene diphenyl diisocyanate (MDI) and solvents was performed. Subjects completed a study-specific questionnaire and underwent anterior rhinoscopy, skin prick tests for common aeroallergens, spirometry, nasal peak inspiratory (NPIF) and expiratory flow (NPEF).

[Assessment of exposure to polycyclic aromatic hydrocarbons in asphalt workers by measurement of urinary 1-hydroxypyrene].

Introduction: Asphalt workers are potentially exposed to polycyclic aromatic hydrocarbons (PAHs). As some PAHs are classified as carcinogenic, the assessment of occupational exposure to these agents is of the utmost importance in preventing toxic effects.

Objectives: To assess exposure to PAHs by urinary 1-hydroxypyrene (1-OHPyr).
