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

The concept of self-management is based on the notion that it will improve wellbeing and strengthen self-determination and participation in health care, while reducing health care utilisation and health costs. Increasing self-management is a desirable goal for the 15%-20% of children and adolescents who have a significant ongoing health care need related to a chronic health condition. Promoting self-management in young people with chronic illness can be difficult for parents and health care practitioners. Doctors can help parents recognise the potentially competing aspects of the parenting role--protecting young people's health while supporting their growing independence and autonomy. Optimal care may or may not be achievable, depending on a young person's level of development. As children mature through adolescence, they increasingly want their own voice to be heard, as well as the right to privacy and confidentiality in health care consultations. As well as listening to parents and supporting their roles, doctors should see young people alone for part of the consultation, taking a psychosocial history and carefully maintaining confidentiality. 相似文献
