Age-related postural deficits elicit compensatory mechanisms such as ankle dorsiflexion in the elderly. To gain further insight into this problem, the ability to match an ankle angle during quiet stance was studied in 12 elderly and 12 young subjects. Following an initial single limb angular perturbation presented in the ±4° range, a subject had to return a tilt platform to level, as determined by the nonperturbed limb. Elderly subjects exhibited significant positive (0.9°) over-shoot of the level position, in contrast to young subjects who matched ankle angle with a mean error of −0.1°. The elderly group also exhibited an increase in positioning error for angular displacements in the range between −1 and +1°. The results document age-related postural changes in ankle positioning which might affect postural stability in older adults. 相似文献

Multiple myeloma: evaluation by CT 总被引:3,自引:0,他引:3
Although patients who have multiple myeloma usually have straightforward clinical symptoms and corroborative radiographs, in some instances, these patients will present atypically, with symptoms suggesting active disease but radiographs that are normal or nonspecific. We reviewed the records of 32 patients who had documented multiple myeloma and had undergone CT examinations, assessing the value of those examinations. Although CT is not indicated in all patients who have multiple myeloma, it is especially useful in patients who have bone pain and normal or nonspecific radiographs. CT provided confirmatory information in all cases in which lesions were seen on radiographs. CT also frequently demonstrated a greater extent of disease than could be appreciated on the radiographs. 相似文献

Insufficiency fractures in the supraacetabular region were identified in five women, aged 55-83 years. Factors contributing to the diminished resistance of their bones included postmenopausal osteoporosis, steroid therapy, radiation therapy, and rheumatoid arthritis. The supraacetabular fractures were seen on routine radiographs as hazy bands of sclerosis located immediately above and parallel to the acetabular roof. All five patients had additional fractures in the spine or pelvis. Supraacetabular insufficiency fractures may be an unsuspected cause of hip pain, especially in older women. 相似文献

Two patients had colonic perforation as a result of percutaneous nephrostomy placement followed by track dilatation and renal calculus removal. We present the technical aspects of nephrostomy placement and stone removal, as well as the clinical diagnosis and management of these cases. Both patients recovered well with conservative therapy and required no surgical intervention. This report reviews the anatomic considerations for percutaneous nephrostomy in patients undergoing renal stone removal. 相似文献

Background: Patients with rheumatoid arthritis face the challenge of adjusting to adverse health consequences and accompanying emotions.
Styles of emotion regulation may affect health.Purpose: The objective is to examine associations between styles of emotion regulation and perceived health, consisting of psychological
well-being, social functioning, physical functioning, and disease activity.Methods: Principal component analysis was used to summarize styles of emotion regulation of 335 patients with rheumatoid arthritis.
Relationships between emotion regulation and perceived health were examined with structural equation modeling.Results: Four styles of emotion regulation were identified: ambiguity, control, orientation, and expression. Ambiguity and control
were mutually correlated, as were orientation and expression. Styles of emotion regulation were not uniquely related to perceived
physical functioning and disease activity. Emotional ambiguity and orientation were related to poorer, whereas expression
and control were related to more favorable psychological well-being and social functioning.Conclusions: Our cross-sectional study suggests that emotion regulation is not of direct importance for perceived somatic health of patients
with rheumatoid arthritis, but it may be of importance for psychological well-being and social functioning, and perhaps through
this route for somatic health. The more conscious and controlled aspects of control and expression are positively related
to psychosocial health, and the more unconscious automatic aspects of ambiguity and orientation are negatively related. Changing
emotion regulation will potentially affect psychosocial health. It would be worthwhile to verify this possibility in prospective
research.

Arterial hypertension is a major cause of morbidity and mortalitybecause of its association with coronary heart disease, cerebrovasculardisease and renal disease. The extent of target organ involvement(i.e. heart, brain and kidneys) determines outcome. North Americanstudies have shown that hypertension is a major contributorto 500 000 strokes (250 000 deaths) and 1 000 000 myocardialinfarctions (500 000 deaths) per annum. 相似文献
