Highway workers, such as policemen, automotive service companies, and toll collectors, are placed at risk of the accelerated atherosclerotic process, since recent studies have suggested that exposure to exhaust particles and ambient air pollution increases carotid intima-media thickness and reduces ocular blood flow velocity. Therefore, we assessed the relationship between serum homocysteine, a potential parameter for atherosclerosis, and the ocular blood flow velocity and the resistivity index in highway toll collectors. The peak systolic and end diastolic flow velocities and the resistivity index were measured in 22 toll collectors and 24 control subjects by color Doppler ultrasonography. The resistivity index, which is an indirect measure of the atherosclerotic process, was calculated: resistivity index = (peak systolic velocity - end diastolic velocity)/peak systolic velocity. Serum homocysteine levels were determined by fluorometric high-performance liquid chromatography. In the highway toll collectors, the serum homocysteine level (14.4 +/- 4.8 micromol/l; p < 0.005) and the resistivity index of the ophthalmic artery (0.741 +/- 0.015; p < 0.05) were higher and the ophthalmic blood flow velocity (33.0 +/- 3.0 cm/s; p < 0.001) was lower than those in the controls (10.6 +/- 3.1 micromol/l; 0.728 +/- 0.023; 36.8 +/- 2.2 cm/s; respectively). There were significant correlations between the serum homocysteine level and ophthalmic artery resistivity index in both highway toll collectors (p < 0.001) and controls (p < 0.005). Exposure to exhaust particles might increase the serum homocysteine level, which in turn could lead to the decreased ocular blood flow and the increased resistivity index. 相似文献

Objectives
To evaluate quality of life (QoL) and related variables in patients with ankylosing spondylitis (AS), a chronic inflammatory disease of the spine.Methods
Nine-hundred and sixty-two patients with AS from the Turkish League Against Rheumatism AS Registry, who fulfilled the modified New York criteria, were enrolled. The patients were evaluated using the Assessment of SpondyloArthritis International Society core outcome domains including Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), fatigue (BASDAI-question 1), pain (last week/spine/due to AS), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrology Index (BASMI), Bath Ankylosing Spondylitis Radiology Index (BASRI), Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) and two QoL questionnaires (the disease-specific ASQoL and generic the Short Form-36 [SF-36]).Results
The mean ASQoL score was 7.1 ± 5.7. SF-36 subscales of general health, physical role and bodily pain had the poorest scores. ASQoL was strongly correlated with disease duration, BASDAI, fatigue, BASFI, BASMI, BASRI, MASES, pain and SF-36 subscales (P < 0.001). SF-36 subscales were also strongly correlated with BASDAI and BASFI. Advanced educational status and regular exercise habits positively affected QoL, while smoking negatively affected QoL.Conclusions
In patients with AS, the most significant variables associated with QoL were BASDAI, BASFI, fatigue and pain. ASQoL was noted to be a short, rapid and simple patient-reported outcome (PRO) instrument and strongly correlated with SF-36 subscales. 相似文献58.

A recurrence of ovarian mucinous cysts is very rare. Over a period of 21 months, a 20-year-old patient had three laparotomies resulting initially in the removal of one ovary with a mucinous cystadenoma and two cystectomies for the same pathology, but ultimately leading to hysterectomy and salphingo-oopherectomy. Because mucinous tumors are usually benign and most of the time multilocular, management of young patients is challenging, especially in the case of recurrence. Follow-up of these patients is very important and transvaginal ultrasound seems to be currently the most effective diagnostic tool for the follow-up of young patients treated with cystectomy for benign mucinous cystadenomas. 相似文献

Correlations of serum prolidase activity between bone turnover markers and mineral density in postmenopausal osteoporosis 总被引:1,自引:0,他引:1
Prolidase is a specific imidodipeptidase involved in collagen degradation. The increase in the enzyme activity is believed to be correlated with the increased intensity of collagen degradation. The aim of this study was to evaluate the serum prolidase activity and its relationship between bone turnover markers and bone mineral density (BMD) in postmenopausal osteoporosis. The study included 45 postmenopausal osteoporotic, 55 postmenopausal nonosteoporotic and 38 premenopausal healthy women. BMD was measured at the femoral neck and lumbar spine with DEXA. T score was more than 2.5 SD below the normal at the lumbar spine or femoral neck in postmenopausal osteoporotic patients. Serum levels of prolidase, C-terminal telopeptide of type I collagen (C-telopeptide), total alkaline phosphatase (ALP), osteocalcin (OC), urinary deoxypyridinoline (Dpd) and urinary creatinine were also assayed. C-telopeptide, total ALP, OC, urinary Dpd levels were significantly higher in postmenopausal osteoporotic group compared with premenopausal women. However, there was no statistical difference in serum prolidase activity between the three groups. There were also no significant correlations between serum prolidase and any biomarkers of bone turnover as well as BMD. To conclude, in postmenopausal osteoporotic women with increased bone turnover, serum prolidase concentration was not correlated with the biomarkers of bone formation or bone resorption and with BMD. 相似文献
