Since the publication of the Revised European-American Classification of Lymphoid Neoplasms in 1994, subsequent updates of the classification of lymphoid neoplasms have been generated through iterative international efforts to achieve broad consensus among hematopathologists, geneticists, molecular scientists, and clinicians. Significant progress has recently been made in the characterization of malignancies of the immune system, with many new insights provided by genomic studies. They have led to this proposal. We have followed the same process that was successfully used for the third and fourth editions of the World Health Organization Classification of Hematologic Neoplasms. The definition, recommended studies, and criteria for the diagnosis of many entities have been extensively refined. Some categories considered provisional have now been upgraded to definite entities. Terminology for some diseases has been revised to adapt nomenclature to the current knowledge of their biology, but these modifications have been restricted to well-justified situations. Major findings from recent genomic studies have impacted the conceptual framework and diagnostic criteria for many disease entities. These changes will have an impact on optimal clinical management. The conclusions of this work are summarized in this report as the proposed International Consensus Classification of mature lymphoid, histiocytic, and dendritic cell tumors.

In the past, occupational health gave scant attention to the visual apparatus. Studies on issues relating to 'work and vision' have predominantly addressed industrial accidents and the toxic effects of exposure to chemical and physical agents, with secondary prevention being more common than primary prevention. In recent years, the huge transformations implemented in workplaces, mainly due to computer-based technologies, demand a progressively higher efficiency of the eye and the related nervous system components that co-ordinate eye movements and accommodation. At the moment these aspects are managed by medical, psychosocial and a variety of technical disciplines, without any shared criteria, terminology and method. Objectives of the Committee are: to investigate holistically the many possible hazards associated to the occupational visual performance; to come to a consensus on terminology, risk assessment and health surveillance procedures. The present status of research and practice in ergophthalmology does not allow for clear-cut decision about health risk and nor is there a clear direction on the prevention of work-related ocular and visual disturbances and disorders. Specifically, at least three determinants must be objectively considered, namely: (a) visual effort; (b) environmental agents; (c) individual characteristics. Although criteria exist for the evaluation of some of these determinants, a greater refinement is necessary 'for a good working life' of the visual apparatus. The ICOH Scientific Committee on 'Work and Vision' is seeking to systematically develop this matter, yielding a more rational and complete approach to the relationship between work and vision.
