Background: A tombstoning pattern (T‐pattern) is associated with in‐hospital poor outcomes patients with ST‐segment elevation myocardial infarction (STEMI), but no data are available for midterm follow‐up. We sought to determine the prognostic value of a T‐pattern on admission electrocardiography (ECG) for in‐hospital and midterm mortality in patients with anterior wall STEMI treated with primary percutaneous coronary intervention (PCI). Methods: After exclusion, 169 consecutive patients with anterior wall STEMI (mean age: 55 ± 12.9 years; 145 men) undergoing primary PCI were prospectively enrolled in this study. Patients were classified as a T‐pattern (n = 32) or non–T‐pattern (n = 137) based upon the admission ECG. Follow‐up to 6 months was performed. Results: In‐hospital mortality tended to be higher in the T‐pattern group compared with non–T‐pattern group (9.3% vs 2.1% respectively, P = 0.05). All‐cause mortality was higher in the T‐pattern group than non–T‐pattern group for 6 month (P = 0.004). After adjusting the baseline characteristics, the T‐pattern remained an independent predictor of 6‐month all‐cause mortality (odds ratio: 5.18; 95% confidence interval: 1.25–21.47, P = 0.02). Conclusion: A T‐pattern is a strong independent predictor of 6‐month all‐cause mortality in anterior STEMI treated with primary PCI. Therefore, it may be an indicator of high risk among patients with anterior wall STEMI. 相似文献

Background
Prolonging atrial conduction time, as measured by tissue Doppler imaging (TDI), is an independent predictor of new onset or recurrent atrial fibrillation (AF). We investigated atrial conduction time and cardiac mechanical function in patients with impaired fasting glucose (IFG) using echocardiography.Methods
Thirty patients with IFG (19 males and 11 females; age, 46.9?±?9.5?years) and 30 control subjects (18 males and 12 females; age, 46.7?±?8.2?years) were included. Atrial conduction time was determined from the lateral mitral annulus (PA lateral), septal mitral annulus (PA septal), and lateral tricuspid annulus (PA tricuspid) by TDI. Inter- and intra-atrial electromechanical delays (EMDs) were calculated. Left atrial (LA) volumes were determined according to the biplane area?Clength method. LA mechanical function parameters were calculated.Results
LA passive emptying volume and LA passive emptying fraction decreased significantly in patients with IFG as compared with control subjects (p?<?0.001 and p?<?0.001, respectively). PA lateral and PA septal durations were significantly higher in patients with IFG than in the control group. However, no difference in PA tricuspid duration was observed between the two groups. Inter- and intra-atrial EMDs were significantly higher in patients with IFG as compared with the control subjects (median [interquartile range], 34.0 [17.0] vs. 17.0 [4.0], p?<?0.001 and 15.0 [8.5] vs. 7.5 [2.0], p?<?0.001, respectively). Positive correlations were detected between both inter- and intra-atrial EMD and glucose levels (r?=?0.76, p?<?0.001 and r?=?0.68, p?<?0.001, respectively). Additionally, a multiple linear regression analysis revealed that glucose levels were independently associated with inter-atrial EMD (???=?0.753, p?<?0.001).Conclusion
We showed that IFG was associated with inter- and intra-atrial EMD. Our findings suggest that IFG is an etiological factor for the development of AF. 相似文献43.

Background
An increase in the number of circulating endothelial cells (CEC) indicates endothelial damage and the risk of cardiovascular disease. The aim of our study was to investigate the association of CEC with various clinical parameters in pediatric renal transplant recipients.Methods
CEC, defined as CD45?CD146+, were enumerated by flow cytometry from the peripheral blood of 50 pediatric renal transplant recipients and 20 healthy controls. Clinical parameters, including renal function tests, fasting blood glucose, serum cholesterol and triglyceride, cyclosporine A (CsA) (trough and 2nd-hour) and tacrolimus (tac) trough blood levels and their association with CEC numbers were analyzed.Results
CEC numbers of patients were higher than those of controls (respectively, 128?±?89 cells/ml (42–468 cells/ml), 82?±?33 cells/ml (32–137 cells/ml), p?=?0.024). There was a statistically significant negative correlation between CEC numbers and glomerular filtration rate (GFR) (r?=??0.300, p?=?0.012). There was also a statistically positive association between CEC numbers and transplant duration as well as cyclosporine trough level (respectively, r?=?0.397, p?=?0.004, r?=?0.714, p?=?0.004). CEC numbers in patients on tac and CsA were similar (p?=?0.716).Conclusions
Our results demonstrate that renal transplant recipients with high CsA trough blood level, longer transplant duration, and lower GFR, are at greater risk of developing endothelial damage. 相似文献44.

Background
The importance of endoscopic evaluation and grading of the gastroesophageal flap valve (GEFV) in patients with gastroesophageal reflux disease (GERD) was previously demonstrated with increased acid exposure and high grades of esophagitis in those with high-grade valves. On the other hand, no data exist on the relationship between GEFV appearance and surgical rate.Methods
For 453 patients with symptoms suggestive of GERD, GEFV grading and 24-h ambulatory pH monitoring were performed. Surgery was performed for 82 of these patients who failed medical management or had disease complications.Results
The GEFV grade 4 patients were younger than the patients with normal GEFV (grades 1 [p = 0.017] and 2 [p < 0.001]) and showed significant male predominance. The prevalence of hiatal hernia, the degree of esophageal acid exposure, and the prevalence and degree of erosive esophagitis significantly increased with GEFV grade (p < 0.001 for all). No GEFV grade 1 patients underwent surgery compared with 4.9 % of the grade 2 patients, 20.5 % of the grade 3 patients, and 63.6 % of the grade 4 patients who had surgery for various indications (p < 0.001).Conclusions
Esophagogastric opening estimated by endoscopic grading of the GEFV was strongly correlated with surgery rate in GERD patients. In particular, patients with grade 4 valves showed the highest rates of erosive esophagitis and axial hiatal hernia and frequently underwent surgery for either failed medical management or disease complications. 相似文献45.

INTRODUCTIONPolyethylene (PE) wear debris after total hip arthroplasty (THA) may cause formation of a soft tissue mass due to inflammatory reaction. To the best of our knowledge we report the first case in whom the diagnosis was made after examination of the hip, pelvis and lumbar spine with detailed radiological methods and the plain radiographs showed no signs of loosening of the THA.PRESENTATION OF CASEWe report a 52 years-old woman who presented with a cyst causing sciatic irritation in her gluteal region due to wear debris after THA. Magnetic resonance imaging (MRI) was useful in detecting the cyst. Resolution of the cyst occured after subtotal cystectomy and revision of the acetabular components.DISCUSSIONAlthough plain radiographs can show signs of the underlying pathology; such as osteolysis, loosening of the components and wear of the PE liner, they are unable to detect cystic lesions. Cystic lesions may be an early sign of wear debris.CONCLUSIONThis case shows us that sciatic neuropathy with no evidence of nerve root impingement on lumbar MRI in a patient with THA requires also examination of the hip and pelvis with detailed radiological methods, such as MRI, in addition to plain radiography. Removal of the source of debris via revision surgery following subtotal cystectomy leads to the resolution of the remaining portion of the cyst and also relief of the symptoms of sciatic nerve compression. 相似文献

Susac's syndrome is characterized by the clinical triad of encephalopathy, branch retinal artery occlusions and sensorineural hearing loss. We here report a case of 46 year old woman with a sudden diminution in visual acuity at the left eye, headache and decreased hearing at the right ear with mild confusion considered as Susac's syndrome with complete triad. Although it's a relatively rare entity, it should be kept in mind in differential diagnosis of the neurological disorders, especially in women in 20- to 40-year of age presenting with acute hearing loss. 相似文献

Objectives: Glioblastoma (GBM), the most common primary tumour of the central nervous system, is characterised by a high malignancy and poor prognosis. The aims of this study were to investigate whether the combination of imatinib mesylate (IM) and lithium chloride (LiCl) exhibited a synergistic effect in treatment and to determine whether midkine (MK) affected the fate of this treatment in vitro.Methods: Monolayer and spheroid cultures of the T98G human GBM cell line were treated with an IM and LiCl combination for 72 h. The cell proliferation index, apoptotic index, cell cycle distribution, apoptotic and anti-apoptotic protein levels, and cAMP level as well as the cellular morphology and ultrastructure were evaluated.Results: All applications inhibited cell proliferation and induced apoptosis. The most substantial decreases in cell proliferation and the caspase-3, epidermal growth factor receptor (EGFR), platelet derived growth factor receptor-alpha (PDGFR-α), multidrug resistance protein-1 (MRP-1), aquaporin-4 (AQP-4) and cAMP levels were induced by the LiCl treatment, which exhibited more pronounced effects compared with the combination treatment. LiCl was less effective in decreasing the MK and B cell lymphoma-2 (Bcl-2) levels compared with the combination treatment. The most substantial decrease in the p170 levels was identified following the combination treatment, whereas IM induced the second greatest decrease. LiCl alone had no effect on the p170 levels. IM induced the most substantial decrease in the phospho-glycogen synthase kinase 3-beta (p-GSK-3β)/glycogen synthase kinase 3-beta (GSK-3β) ratio, and LiCl induced the second most substantial decrease. Both LiCl and the combination treatment induced G2 + M arrest, whereas IM induced G0 + G1 arrest after 72 h of exposure. An apoptotic appearance and autophagic vacuoles were commonly identified in the LiCl, combination and IM groups, respectively.Conclusions: The combination of IM and LiCl exhibited an antagonist effect, and MK had a role at this antagonism. 相似文献

AbstractSerial magnetic resonance (MR) imaging has not yet been validated in the therapy of experimental intracerebral hematomas in a rat model. It is possible to test the effect of local fibrinolysis and aspiration on the clot volume using serial magnetic resonance imaging and different MR-sequences. Experiments were carried out in 22 male Sprague-Dawley rats. Intracerepra I hematoma was produced by injection of fresh autologous blood into the caudate nucleus using a double injection technique. Thirty minutes later 70 rats were treated by injecting 12 µl of recombinant tissue plasminogen activator. MR-imaging was performed immediately after generation of the hematoma and after clot lysis. The clot volume measured in the magnetic resonance images was compared with that obtained in stained histological serial sections at the end of the experiment. Serial MR scanning demonstrated a significant reduction (p<0.07) of hematoma volume after fibrinolysis followed by aspiration of the blood clot. The best correlation between MR- and histological volumetry was found on RF-spoiled FLASH 2D-images. This study documents the efficacy of MRI in detecting and delineating the size of acute intracerebral hematomas and its time course. Local fibrinolysis and aspiration can be simulated in an experimental rat model. [Neural Res 1998; 20: 349-352] 相似文献
