    Summary: Radiological Safety and Quality - Paradigms in Leadership and Innovation is a multi-disciplinary and inter-sectorial collaboration by international experts and leaders from academic institutions, radiology practices, professional organizations, regulatory authorities, UN and international agencies. Established principles and new concepts, challenges and opportunities, and examples of leadership and innovations are discussed to raise awareness, share experience and facilitate development of facility-based or system-wide improvements in radiation safety, quality radiology, and patient care by procedure justification, optimization of protection and imaging data, and incident minimization. The 26 chapters by 53 experts and 11 messages from international organizations and agencies convey a common theme: there is no single panacea to improve radiological safety and quality but on-going leadership, innovation, collaboration, and stakeholder participation are needed.

    Immunostimulation with levamisole was attempted in eight patients with juvenile periodontitis and six reference patients with gingivitis but without loss of periodontal attachment. The following parameters were studied before and after levamisole treatment: gingival status, the concentration of serum immunoglobulins and complement, T and B lymphocyte ratio, leukocyte migration inhibition and lymphocyte transformation responses by dental plaque bacteria, PPD or PHA, and lymphocyte ATP-ase activity. In juvenile periodontitis cell-mediated immunity to dental plaque antigens seemed to be impaired, but the response was not restored by treatment with levamisole. There was no evidence of a broader suppression of cell-mediated immunity in juvenile periodontitis and there was no significant clinical effect of levamisole treatment. It is suggested that the apparent suppression of in vitro cell-mediated immunity to dental plaque bacteria in juvenile periodontitis is a secondary change, caused by a long-standing chronic infection.
