Objective
The aim of this study was to assess the accuracy of ultrasound elastography as a recent imaging technique in diagnosis of CTS and evaluation of its severity in patients suffering clinically compared to the results of the gold standard electrophysiological tests.Materials and methods
This was a prospective cross sectional study included 100 patients clinically diagnosed as having unilateral idiopathic CTS (90% of the dominant hand), referred to radiology department from physical medicine department at Alexandria main university hospital from June 2015 till May 2016 after being evaluated electrophysiologically for correlation with the data of the ultrasound and ultrasound elastography of the median nerve. A control group of 100 patients with no wrist or hand complain were included in the study.Results
As diagnosed electrophysiologically, there were 44 (44%), 35 (35%) and 21 (21%) patients with mild, moderate and severe degree of CTS respectively. The mean cross sectional area of the median nerve among the studied cases was 12.19?±?1.59?mm2 while the mean strain ratio of the median nerve by ultrasound elastography was 2.20 (1.0–5.0).Conclusion
In addition to electrophysiological study, ultrasound and ultrasound elastography are valuable tools for the diagnosis and classification of CTS. 相似文献92.

Background
This study compares the differences in acetabular component position, leg length discrepancy, and hip offset between the anterior and posterior approach. A novel method is applied to determine the acetabular anteversion using the C-arm tilt angle for the anterior approach.Methods
Hundred consecutive anterior total hip arthroplasties were matched according to gender, body mass index, and age to a cohort of 100 primary total hip arthroplasties operated on through a posterior approach. Postoperative radiographs were analyzed to determine cup inclination, cup anteversion, leg length discrepancy, and hip offset.Results
The mean inclination was 40.8° (range 33°-48°) and 45.1° (range 33°-55°) for the anterior and posterior approach, respectively. Using the new C-arm tilt plane technique, an average acetabular anteversion of 18.4° (range 11°-26°) was achieved with the anterior approach compared with 23.6° (range 8°-38°) with the posterior approach. Hundred percent cups in the anterior group and 81% in the posterior group fell within the safe zone (P < .001). There was no difference in the overall hip offset between the operated side and the contralateral side for the anterior (P = .074) and posterior (P = .919) group. There was no difference in leg length discrepancy between the 2 approaches (P = .259).Conclusion
Intraoperative fluoroscopy-assisted direct anterior approach was associated with improved acetabular component positioning. However, no benefit was shown with regards to restoration of hip offset or leg length. 相似文献93.

免疫反应的产生首先是由抗原提呈细胞(antigenpresenting cells,APC)捕获抗原,经其加工处理后将抗原信息传递给T,B淋巴细胞,从而引发一系列的特异性免疫应答.APC包括树突状细胞(dendritic cells,DC)、巨噬细胞(MΦ)、B细胞等,其中DC是人体内最具潜能的抗原提呈细胞(APC),能在体内外直接激活纯真(naive)T细胞,提呈抗原给MHC-Ⅰ类限制性CD8+和MHC-Ⅱ类限制性CD4+T淋巴细胞,诱导特异性免疫应答[1-6]. 相似文献

In this work, the quantitative determination of an erectile dysfunctional drug avanafil in the presence of its acid-induced degradation product was achieved via the application of a pre-optimized novel spectrofluorimetric method. The fluorescence emission wavelength was recorded at 370 and 407 nm, after being excited at 268 and 271 nm for avanafil and its acid-induced degradation product, respectively. Direct determination of avanafil based on its native fluorescence is restricted because the emission spectra of both components are heavily overlapped. Therefore, to overcome this constraint, a novel second derivative synchronous fluorescence method was evolved to eliminate this overlapping. The ideal determination wavelength was found to be 377 nm. Augmentation of lean six sigma (LSS) with response surface methodology (RSM) play a significant role in the development of robust specifications to ensure quality at the six sigma level with a high level of statistical confidence and targeted performance. All of the experimental conditions were optimized using D-optimal design as a RSM to select the optimal parameters. In addition, this work includes a graphical representation of the relationships between various variables that can greatly affect the results and the intensity of the synchronous fluorescence.In this work, the quantitative determination of an erectile dysfunctional drug avanafil in the presence of its acid-induced degradation product was achieved via the application of a pre-optimized novel spectrofluorimetric method. 相似文献

Background: Different imaging techniques can be used for assessment of chest problems in ICU patients, however ultrasound is a good diagnostic tool giving more information and at the same time without exposure to radiation and without risk of critical patient transfer.Aim of the work: The aim of this work was to study the role of thoracic ultrasound in assessment of ICU patients.Materials and methods: The study was carried out on 30 patients admitted to the ICU.B and M modes chest ultrasound was done for all patients using EsaoteMyLab?Alpha with eHD Technology.Results: The study included 19 males and 11 females with mean age of 42.6 ± 21.4 years. In this study ultrasound was able to diagnose Pneumothorax: 3 cases (10%). Pleural effusion: 20 cases (66.6%). Alveolar interstitial syndrome: 7 cases (23.3%). Lung consolidation: 20 cases (66.6%). Pulmonary infarcts: 1 case (3.3%). Neoplastic disease: 1 case (3.3%). Chest wall pathology: 1 case (3.3%).Conclusion: Ultrasound examination of the chest is a non- invasive, and promising bed side tool for examination of ICU patients. 相似文献
