A patellar brace with a lateral pad was used in 25 patients with unilateral retropatellar pain syndrome. The patients were told to use the brace in activities that loaded the patella, and they were followed for 1 to 2 years. At follow-up, 8 patients were improved, while the symptoms were unchanged or worse in 17. The level of activity was increased in 4 patients, reduced in 3, and unchanged in the others. It is concluded that treatment with a patellar brace with a lateral pad is not likely to succeed in the majority of patients with retropatellar pain syndrome. 相似文献

Three cases with suspected pulmonary artery embolism are presented, in which transesophageal echocardiography showed a mass in the right pulmonary artery consistent with thrombus. The relevant diagnostic contributions of transesophageal echocardiography are discussed. 相似文献

The database of the Hungarian randomised controlled trial of periconceptional multivitamin supplementation for the prevention of neural-tube defects was used to evaluate the length of the pre- and postovulatory phases of the menstrual cycle before and during multivitamin supplementation. The female cycle was more regular (i.e., the variance was lower) during the multivitamin supplementation. 相似文献

The results of 194 consecutive interlocking nailings for 95 fractures in the tibia and 99 fractures in the femur with a median observation time of 22 months are presented. Three fractures were not consolidated radiologically at follow-up; three deep infections were recorded, all of which healed. Shortening > 1cm was recorded in 17 fractures, rotatory malalignment > 5 ° in 21, and angular malalignment > 5 ° occurred in 17. The end result was excellent in 121 fractures, good in 41, fair in 28, and poor in 4. 相似文献

The CT-examinations of 15 patients with blow-out fractures of the orbital floor were reviewed. All patients were examined with coronal/semicoronal CT-imaging, and 7 patients also were evaluated with semisagittal projections. Only in one case the semisagittal images gave more information than coronal sections when using the classification of Gilbard et al. (1985) of the inferior rectus muscle/fracture relationship. The anterior and posterior fracture margins were better delineated with semisagittal imaging. Two patients exhibiting positive traction tests with hooked, and not entrapped muscles on CT still had diplopia 5 1/2 and 12 weeks after the trauma. 相似文献

The duration of the late exteroceptive suppression period (ES2 ) of temporal muscle EMG activity has been reported to be reduced in patients suffering from chronic tension-type headache. Methods of recording and analysing ES2 have varied between centers and reproducibility of results within subjects , although insufficiently studied, has generally been poor. ES2 was investigated in 30 healthy subjects, using a computerized technique of recording, rectifying and averaging the EMG signals. Hour to hour and week to week variations of ES2 durations were calculated, and the influence of pain during a cold pressor test and of sustained muscle contraction on ES2 durations was investigated. The intra-individual variation of ES2 durations was 16.0% from hour to hour and 20.7% from week to week. The inter-individual variation was 36.7%. The present method for analysis of ES2 periods proved to be reliable, as the intra-observer variation was 4.2% and the inter-observer variation 4.6%. ES2 periods were significantly shorter on the first compared to the second day of examination ( p = 0.006) and during experimental pain ( p = 0.0005). We recommend the use of the computerized averaging technique in future studies and caution against the dependence of results upon factors such as conditioning and pain. 相似文献

A retrospective cohort study of mortality and cancer morbidity was carried out among 295 marine engineers and 182 machinists with special regard to cancer of the lung. The cohort was defined as all graduates from engineering and machinists school in Iceland during 1936-1955. During vocational training, as well as in their professional lives, marine engineers and machinists are exposed to asbestos, different kinds of mineral oils, and exhaust gases with marked individual variation as regards mode and magnitude of exposure. For deaths occurring between 1951 and 1982 information was obtained from the Statistical Bureau of Iceland. Significantly increased standardized mortality ratios were determined for cancer of the trachea, bronchus, and lung for the entire cohort. Record linkage with the Cancer Register revealed 36 cancers in the period 1955-1982. No statistically significant excess was found for the overall cancer incidence or for the incidence of cancer at any particular site. A special survey of smoking status showed that cigarette smoking was not as common among the subjects of the cohort as among the general male population in Reykjavik. These results support the suggestion that the increased mortality of lung cancer in the study group had a causal relationship to occupational exposure, particularly to asbestos exposure. 相似文献
