[en] Simultaneous scintigraphic and X-ray examination has been evaluated in 30 patients with Paget's disease for estimation of extension and activity of the disease. Scintigraphy produces a comprehensive picture of the pathophysiologic condition. When compared with X-rays the procedure is more economic with regards to cost, time and radiation dosage. Therefore, the use of radioisotopes for evaluation of the skeleton is strongly recommended for follow-up examination in Paget's disease. (Author)
[en] Dysplasia epiphysealis multiplex (DEM) is a generalized affection of the skeletal system involving the hips, knees, feet, shoulders, elbows and hands as well as the spine. It presents complex diagnostic problems, especially in babies and small children, in whom the symptoms are not distinctly developed. From the clinical points of view, DEM has to be distinguished from Perthes' disease. (author). 5 refs
[en] To determine the efficacy of a screening system for developmental hip dysplasia (DHD) involving ultrasound (US), for use in newborns with malformation or risk of DHD. Of the 6,513 infants born in our hospital over a two-year period, 461 (7,07%) were enrolled in the present study. All underwent an initial US study according to Graf's method at the age at the age of one month, with the exception of those infants who presented physical malformation, in whom it was performed within the first 5 days of life. A second study was carried out at the age of three months. Twenty-eight (4.3%) of the newborns included in the screening were diagnosed as having DHD. During the study period, a second group of 21 children (3.2 per thousand) who were nor enrolled in the screening program were diagnosed as having late-onset DHD. Of these 49 patients, 28 required braces and 4 underwent surgery; these 4 all belonged to the late-onset group (rate of treatment: 4,9 per thousand). When the present results were compared with those of a similar previous series, it was observed that the early detection program did not result in over treatment and that the number of cases of late-onset DHD, the severity of DHD and the aggressiveness of treatment had diminished. The systemic performance of a second US study of the age of three months proved to be ineffective. (Author) 19 refs
[en] This study was carried out to evaluate the effect of general and occupational characteristics musculoskeletal symptoms in Radiological Technologist who working in present department more than 1 year. Standardized questionnaire of NIOSH and organized questionnaire for related musculoskeletal was to 72 Radiological Technologist, employed in 6 general hospital in Seoul in September, 2003. The symptom prevalence rate of musculoskeletal symptoms were neck (33.3%), shoulder (33.3%), arm(12.5%), hand(13.9%), spine(34.7%) leg/knee/foot (31.9%), arm/wrist/hand (16.5%).
[en] Radiographs are a well-accepted tool in diagnosing periodontal bone lesions and making an accurate evaluation of the treatment. However, the assessment of bone is hampered by the complicated and as it were unpredictable pattern of bone structure. Therefore, and to compensate for the bias always present in human observations, a computer aided procedure was developed to detect and describe periodontal bone lesions. This paper describes a comparison of the performance by human observers and of the computer program. Two series of artificial periodontal bone lesions served as material for the assessments. This study shows that the automated lesion detection program enables an assessment of periodontal bone lesions, which is at least comparable with the results of a group of experienced observers and probably better. It is considerably better than the results of observers individually, and decreases the time-dependent variability appearing in repeated assessments of a single observer. The computer aided detection of periodontal lesions can be considered as a useful and reliable tool in periodontal diagnosis. 9 ref.; 2 figs
