Takayasu's arteritis is a rare chronic vasculitis of unknown etiology. Symptomatic pulmonary artery disease may be the first sign of Takayasu's arteritis. We describe a 51-year-old woman who presented with severe dyspnea. The initial evaluation and routine exams suggested the presence of pulmonary hypertension of unknown etiology. Absence of bilateral radial and brachial pulses in the physical examination led to an angiographic study, which confirmed the diagnosis of Takayasu's arteritis with severe pulmonary hypertension. During bosentan therapy, the patient's clinical symptoms and exercise capacity improved and her 6-min walking distance increased. We emphasize the importance of considering Takayasu's arteritis in the early diagnosis and therapy of pulmonary artery hypertension. 相似文献

The protective effect of darbepoetin alfa on experimental testicular torsion and detorsion injury 总被引:1,自引:0,他引:1

AIM: Testicular torsion is a serious urological emergency, usually involving newborns, children, and adolescents which can lead to subfertility and infertility. Prevention of testicular damage caused by torsion is still a clinical and experimental problem. So far many chemicals and drugs have been investigated for decreasing ischemia/reperfusion (I/R) injury in experimental animals. The possible protective effect of darbepoetin alfa, a novel erythropoietic protein, on testicular tissue after I/R injury was examined in this study. METHODS: Thirty rats were divided into three groups: sham operation, torsion/detorsion, and torsion/detorsion plus darbepoetin alfa groups. After torsion (2 hours) and detorsion (4 hours), bilateral orchiectomy was performed. Malondialdehyde, nitric oxide and glutathione levels were determined in testicular tissue. RESULTS: Administration of darbepoetin alfa caused a decrease of malondialdehyde and nitric oxide levels and an increase in glutathione levels compared with the torsion/detorsion group. In addition, histological injury scores were significantly decreased in the treatment group more than the torsion/detorsion group. CONCLUSION: The results suggest that darbepoetin alfa may be a potential protective agent for preventing testicular injury caused by testis torsion. 相似文献

Association between paraoxonase 1 activity and severity of coronary artery disease in patients with acute coronary syndromes 总被引:3,自引:0,他引:3

OBJECTIVE: We sought to investigate serum paraoxonase/arylesterase activities in patients with acute coronary syndromes (ACS) and their correlations with the severity and extent of coronary artery disease (CAD). METHODS AND RESULTS: Three groups of patients were investigated: 89 patients with ACS, 54 patients with normal coronary angiograms (no-CAD group), and 27 healthy comparison subjects. ACS patients were divided into three groups according to their clinical presentation: unstable angina pectoris (UAP, Braunwald III-B, n = 31), non-ST elevation myocardial infarction (NSTEMI) (n = 27), and ST-elevation myocardial infarction (STEMI) (n = 31). Serum paraoxonase/arylesterase activities were measured spectrophotometrically. Angiographic CAD extent was expressed both by the number of vessels diseased and by the Gensini scoring system. Results showed that serum paraoxonase/ arylesterase activities and the paraoxonase/high density lipoprotein-cholesterol (HDL-C) ratio were significantly lower in the STEMI, NSTEMI, UAP groups than in no-CAD and control groups. Serum paraoxonase/arylesterase activities and paraoxonase/HDL-C ratio were reduced in patients with 2-vessel disease (VD) and 3-VD compared to the I-VD and no-CAD group (P < 0.001). In patients with ACS, the Gensini score correlated inversely with serum paraoxonase (r = -0.419, P < 0.001), arylesterase (r = -0.492, P < 0.0001), and the paraoxonase/HDL-C ratio (r = -0.377, P < 0.001). Serum arylesterase (r = 0.161, P = 0.03) and paraoxonase (r = 0.135, P = 0.002) activities were positively correlated with HDL-C levels. Serum arylesterase activity (P < 0.0001), gender (P = 0.0037), diabetes mellitus (P = 0.005) and LDL-C levels (P = 0.03) were independent predictors of CAD presence. CONCLUSIONS: Serum paraoxonase/arylesterase activities are reduced in ACS patients and inversely correlated with the severity of CAD. 相似文献

The purpose of this study was to measure isokinetically glenohumeral joint movement peak torque and work in professional basketball, volleyball, handball and baseball players and determine whether significant differences exist between the dominant and non-dominant extremity in athletes and controls. Eighty healthy professional overhead athletes (basketball, volleyball, handball and baseball players) and 20 controls were tested bilaterally on a CYBEX 6000 isokinetic dynamometer at 60 degrees and 180 degrees s(-1) for diagonal pattern of the glenohumeral joint. A standardized protocol and testing guidelines were strictly followed. The range of motion of internal rotation (IR) on the dominant side of baseball players was significantly smaller than those on the dominant side of basketball, handball and volleyball players, and controls (P<0.01). Flexion/abduction/external rotation were consistently higher on the dominant arm (8.5%) for peak torque at 60 degrees s(-1) in baseball players, and bilateral ratios were lower on the dominant arm (14.8%) for peak torque at 180 degrees s(-1) in basketball players. The results of this study are important for the application and interpretation of isokinetic data and flexibility and mobility characteristics on unilaterally dominant overhead athletes. Functional weakness in external rotators, mobility impairments in IR and muscle imbalance have been shown in the dominant arm of these overhead athletes. 相似文献

Rehabilitation of avulsion fracture of the tibial tuberosity following Osgood-Schlatter disease 总被引:1,自引:1,他引:0
G.?BaltaciEmail author H.??zer V.?B.?Tunay 《Knee surgery, sports traumatology, arthroscopy》2004,12(2):115-118
A sixteen-year-old boy suffered from sharp pain in the knee during a jump while playing basketball. He had a positive history of Osgood Schlatter disease. Radiographic evaluation demonstrated an avulsion fracture of the tibial tuberosity Type III according to the classification of Watson-Jones. Rehabilitation after avulsion fracture of the tibial tuberosity is an important consideration for this relatively uncommon adolescent injury. In such avulsion fractures, landing on the ground with the knee fully extended after a jump is the most likely cause. This case report reviews the rehabilitation program, and selected functional outcome measures after rehabilitation are reported. The patient returned to sporting activity after 12 months. 相似文献
