[RANKL-specific denosumab in the treatment of osteoporosis - Possible adverse effects of long-term use]

TANKÓ László

[According to the results of a recent clinical trial, the antiresorptive effect of a single 60-mg injection of denosumab, a monoclonal antibody specific to RANKL (receptor activator of NFκB ligand) substantially exceeds the effect of alendronate (70 mg weekly). Despite these differences, 1-year increases in bone density at the lumbar spine are virtually identical for both agents. The author summarizes experimental and clinical observations illustrating potential consequences of osteoclast deficiency and a constantly low rate of bone resorption for osteoblast function, bone mineralization, bone quality parameters, and mechanical properties, which all may have important implications for bone fragility. These observations also raise the question whether treatment efficiency is truly improved by aggressively pushing the limits of antiresorptive action.]

[Denosumab - pharmacokinetic and clinical evidences]

MÉSZÁROS SZILVIA

[Denosumab is a fully human monoclonal antibody to RANKL modifying bone resorption in a rapid, sustained and reversible way. In postmenopausal women with low bone mineral density, denosumab 60 mg every 6 months increased mineral density, and reduced bone turnover. In postmenopausal women, it reduced the risk of vertebral, hip, and non-vertebral fractures. Increase in body mass index and reduction in bone turnover was more pronounced with denosumab than with alendronate. In patients who were switched from alendronate to denosumab, positive effects on bone were more pronounced than in those continuing alendronate. Denosumab was safe and well tolerated, and it holds the promise of becoming an efficacious therapy for postmenopausal osteoporosis.]

[Management of hip fractures: practice, results, and problems in the last decade]

KRICSFALUSY Mihály, FLÓRIS István, CSERHÁTI Péter

[Among fractures attributable to osteoporosis, hip fractures are associated with the most severe consequences and the greatest costs. Surgical therapy for this condition is continuing to improve. Increasingly recent implants and techniques are being developed and introduced to successfully control postoperative adverse events. The authors briefly outline actual practice in Hungary and present some results of the follow-up of their patients in the last decade. These show that, in order to improve outcomes of hip fracture patients, all domains of management need to be addressed.]

[Education and psychological support of parents in cases of postnatally detected Down syndrome]

MÁTÉ Orsolya, KÍVÉS Zsuzsanna, OLÁH András, FULLÉR Noémi, PAKAI Annamária

[OBJECTIVE - Since the 60’s several publications dealt with the phenomenon how physicians inform parents of newborns about postnatal recognition of Down’s syndrome and the support they receive right after breaking the bad news. Howe - ver, the rest of these studies concentrated on surveying parental satisfaction, while relatively few international studies deal with the other side of the communicational situation, the opinion of the informer. Our study focused on the circumstances of parental information in Hungarian institutions of obstetrics in order to evaluate the possibilities for interventions. METHODS - The Down’s team operating at the University of Pécs Faculty of Health Sciences carried out a national survey in 2005 - an interview-based questionnaire filled by physicians of institutions of obstetrics - with the help of the National Register for Congenital Diseases of the National Centre for Epidemiology and Down’s Foun dation. RESULTS - The coverage of the survey reached 74%. Rest of the surveyed institutions did not have information protocol, however, 70% of them believes it would be necessary. Only 44% of the physicians received communication training and 81% of them believe they can manage communication, 33% have felt that the mother of a newborn with Down’s syndrome would expect special help that the institutions are unable to provide. CONCLUSION - There are serious problems with the circumstances of parental informing in Hungarian institutions of obstetrics. This situation would obviously require intervention. An aimed communicational training based on international experience and exploiting the openness of physicians, as well as the establishment of information protocol could be elements of such intervention.]
