The Evonik-Mainz-Eye-Care-Study (EMECS): design and execution of the screening investigation.

Purpose: To determine if screening for major ophthalmological diseases is feasible within the frame of routine occupational medicine examinations in a large working population.

Methods: 13037 employees of Evonik Industries aged 40 to 65 years were invited to be screened for major ophthalmological diseases (glaucoma, age related macular degeneration and diabetic retinopathy between June 2007 and March 2008 within an extended setting of occupational medicine. Ophthalmological examinations consisted of visual acuity, objective refraction, pachymetry, tonometry, perimetry (frequency doubling technology), confocal scanning laser ophthalmoscopy and digital fundus photography.

Shift work, chronodisruption and cancer?--The IARC 2007 challenge for research and prevention and 10 theses from the Cologne Colloquium 2008.

In October of 2007, an IARC panel of 24 scientists systematically evaluated epidemiologic, experimental, and mechanistic data and concluded that shift work that involves circadian or chronodisruption is probably carcinogenic in humans. In view of the possible scope of the problem--shift work is widespread and unavoidable on one hand and breast cancer and prostate cancer, which may be causally associated with chronodisruption, are epidemic worldwide on the other--German representatives of science and occupational medicine discussed the experimental and epidemiologic background and possible implications of the challenge identified by the International Agency for Research on Cancer (IARC) at a colloquium in Cologne in September 2008. This overview summarizes the key ideas presented at the Cologne Colloquium and offers 10 theses concerning the need for targeted studies and the necessity to develop possible means of prevention.

Platinum concentrations in sera of catalyst production workers are not predictive of platinum salt allergy.

Platinum (Pt) salts are potent occupational allergens in precious metal refineries and catalyst productions. The threshold limit value of 2000 ng soluble Pt/m3 enforced in many countries has been questioned because there is still a high incidence of Pt salt allergy. The objective of the present case series is to define the predictive value of biological monitoring by relating Pt in the serum of catalyst production workers and control subjects to sensitization to Pt salts as assessed by skin prick testing.
