Main and interactive effects of shiftwork, age and work stress on health in an Italian sample of healthcare workers.

Among healthcare workers, shiftwork (mostly if nightwork is also included), ageing and work-related stress may be factors leading to impaired health. Such risk factors may also operate in interaction, resulting in an even increased harm for health. The present study aims at evaluating these relationships in a sample of 1842 hospital workers in Northern Italy.

[Clinical aspects, etiology, pathogenesis, diagnosis and therapy of aseptic bone necrosis--a current analysis of the literature].

With continuous proliferation of magnetic resonance imaging early detection of avascular bone necrosis becomes progressively important for treatment of early disease stages. The last decades intensified research on the field of ostoenecrosis has lead to different etiopathogenetic models and to new treatment options. Thereby long term results of known operative interventions are now available.
