Can we identify the poorest quality of life? Assessing the importance of quality of life using the WHOQOL-100

In this study, WHOQOL survey data obtained from 4802 sick and well participants in 15 countries were used to investigate the relationship between judgements about different dimensions of quality of life (QOL) (core scores) and the importance attributed to them. As a theoretical framework, we applied the WHOQOL Group's (1995) definition of QOL which indicates that those who report the very poorest QOL will be least likely to have met their own '...goals, expectations, standards and concerns'. Those with the poorest QOL would therefore be expected to show the biggest difference between core and importance scores, and therefore be distinguishable from respondents whose QOL was poor, better or best. The main effects from overall analyses confirmed that those reporting the largest negative differences tended to report the poorest QOL and also attached a high degree of importance to these dimensions. Evidence for a decreasing differential across the four groups (poorest to best) was confirmed for the majority (18) of facets. However facet level analyses comparing groups with different levels of QOL showed that only five facets distinguished those with the poorest QOL from those whose QOL was poor, so the theory is not well supported. Furthermore the contribution of core-importance facet differences reduced the overall prediction of QOL, when compared with a regression of core scores alone. Importance information about specific facets may have limited potential to be used alongside the main instrument to identify areas of the poorest QOL for clinical or social action.

Video-fluoroscopic study of swallowing in children with neurodevelopmental disorders

BACKGROUND: Children with neurodevelopmental disorders can have feeding problems. Malnutrition and recurrent aspiration pneumonia can increase the risk of morbidity and mortality. Video-fluoroscopic study of swallowing (VFSS) is essential in understanding the pathological mechanisms involved during swallowing. METHODS: The aim of the present study was to assess the role of VFSS in assessment and management of four children with various neurodevelopmental disorders in a multidisciplinary feeding team. We describe the team approach, with the participation of child neurologist, radiologist with the rehabilitation team including the speech therapist, occupational therapist and dietician, in the assessment and plan of management. RESULTS: Video-fluoroscopic study of swallowing had been useful in assessing the type of swallowing problems with treatment goals targeted to the basic underlying pathophysiological mechanism. CONCLUSION: A child neurologist should be involved in the multidisciplinary oromotor rehabilitation program for neurologically impaired children with feeding problems.     

Histological findings after angioplasty using conventional balloon, radiofrequency thermal balloon, and stent for experimental aortic coarctation

Abstract Background : Use of balloon angioplasty or stent implantation has been reported to be effective in relieving coarctation of the aorta. However, restenosis frequently occurs after balloon angioplasty for native aortic coarctation in small infants, and sometimes develops after stent implantation because of vessel growth. The causes of restenosis remain uncertain. The purpose of this study was to assess the histologic differences in vascular responses to angioplasty using conventional balloon, radiofrequency thermal balloon (RFTB), or stent for experimental aortic coarctation. Methods : The authors surgically created an aortic coarctation model using 14 puppies. Angioplasty using conventional balloon, RFTB, or stent was performed 1 month after the initial operation. At the acute or chronic phase after angioplasty, the animals were killed and histologic studies were performed. Results : More vascular injuries were noted in the specimens from animals undergoing conventional angioplasty than in those with RFTB or stent. However, neointimal hyperplasia was seen more often after RFTB or stent because of the proliferation of smooth muscle cells from the tunica media, caused by secretion of growth factors. Apoptosis reached a peak 1?2 weeks after angioplasty, regardless of the type of intervention. Conclusions : The authors conclude that angioplasty with RFTB or stent can provide relatively small injuries in the vessel wall for aortic coarctation, but care must be taken to prevent restenosis caused by intimal hyperplasia, because neointima hyperplasia is more frequent after RFTB or stent.
