摘要:

Osteoporosis is a major health problem in Australia, as it is in most Western societies. Bone mineral density in the spine and femoral neck are accurate indicators of osteopenia and thus useful indicators of the risk of a fracture. Dual‐photon absorptiometry is a non‐invasive technique that allows the accurate quantitation of bone mineral density in the lumbar vertebrae and proximal femur with a low radiation exposure. The increasing availability of this technique dictates the requirement for “normal” ranges and quality control. We report here lumbar vertebral and proximal femur bone mineral density as measured by dual‐photon absorptiometry in 179 normal Australian women. Forearm bone mineral content in these subjects, as measured by single‐photon absorptiometry, is also presented. There was a relative stability of lumbar bone mineral density and forearm bone mineral content before the menopause, after which there was an age‐related decline. On the other hand, bone mineral density at all three sites in the proximal femur showed an age‐related decline throughout adult life. Intraoperator variability in calculated bone mineral density did not exceed 2.3%. The requirement for correct positioning of the patient is illustrated. The data allow statistical analysis and the development of normal ranges. They provide an Australian base against which individual patient values can now be compared.

摘要:

In order to evaluate forearm osteodensitometry for its potential to detect subjects with a low spinal mineral content and/or vetebral fractures, single‐photon absorptiometry of the forearm and estimations of spinal mineral content by computed tomography were performed in 124 normal and abnormal subjects. Eighty‐one per cent (22/27) of patients with vertebral crush fractures had a low spinal mineral content. In contrast, among 64 apparently normal individuals, six patients (four women, two men; 9.4%) had a low spinal mineral content. Forearm osteodensitometry showed a significant positive correlation with spinal mineral content. A forearm value in women in excess of 35 arbitrary units was associated with a spinal value of 75.1‐mg equivalent dipotassium phosphate (K2HPO4) or above in 29/31 cases. A forearm value in women of 28.5 arbitrary units or lower was associated with a spinal value of 75‐mg equivalent K2HPO4or less in 20/24 subjects. While of no predictive value for the spine in patients with intermediate readings, forearm osteodensitometry is nevertheless considered a useful screening procedure for spinal osteoporosis.

摘要:

Forearm bone mineral density was measured in 557 postmenopausal women from whom a history of fractures was also obtained. Known cases of osteoporosis were excluded. The mean age of the subjects was 59 years. Ninety‐eight of the subjects had sustained a fracture since the menopause and 37 had done so before the menopause. There had been 188 fractures in all. The mean bone density was significantly lower in the subjects who had experienced a fracture than in those who had not experienced a fracture; this was also true of subjects who had suffered a fracture before the menopause. The lowest bone densities were observed in subjects who had suffered forearm fractures, followed by those who had suffered fractures of the rib, ankle and foot. The mean bone density in subjects with more than one fracture was significantly lower than in those with only one fracture. The difference in bone density between subjects with and without a history of fractures was most significant in the younger subjects and became progressively less significant with age. The estimated relative fracture risk was 3.1 in the group with the lowest bone densities and zero in the group with the highest bone densities.

摘要:

Fifty consecutive patients with chronic airflow obstruction who were admitted to a respiratory unit were assessed medically and psychiatrically. A high rate of psychiatric morbidity (58%) was detected with panic and other anxiety disorders (34%) being particularly prevalent. Various physiological and psychological reasons, for the high rate of anxiety disorders are discussed.
