Demonstrating the relationship of ultrasonographic parameters with disease activity and pain in lateral epicondylitis

To evaluate the relationship of ultrasonographic evaluation parameters with pain, muscle strength and disease severity in lateral epicondylitis (LE). 64 people were included in present retrospective, cross-sectional study. Activity and rest pain was questioned with Visual Analog Scale (VAS). Also, Patient Rated Tennis Elbow Evaluation (PRTEE) and the maximum grip strength were evaluated. Hypoechoic region, neovascularity, cortical irregularity, enthesopathy and peritendinous fluid or bursitis were evaluated by ultrasonography. 48 of the patients were female and 16 were male. Mean age was 48.53 ± 6.12, body mass index was 27.70 ± 4.75. 55 (85.9%) hypoechoic region, 31 (48.4%) neovascularity, 21 (32.8%) cortical irregularity, 19 (29,7%) enthesopathy, and 18 (28.1%) peritendinous fluid or bursitis were detected by ultrasonography. When the ultrasonographic findings and clinical findings of the patients were compared, no significant difference was found between the hypoechoic region, cortical irregularity, enthesopathy and clinical findings (P > .05), while the extension grip strength was found to be significantly lower in patients with neovascularity (P = .045). In addition, patients with peritendinous fluid or bursitis, were found to be significantly lower in both flexion (P = .033) and extension (P = .023) grip strength, while PRTEE function (P = .021) subgroup and total (P = .038) scores were significantly higher. Hypoechoic region, cortical irregularities and enthesopathy were not evaluated to be associated with disease severity, pain and muscle strength. Neovascularity was found to be associated only with extension grip strength. Peritendinous fluid or bursitis was found to be associated with both flexion and extension grip strength and disease activity, but not associated with pain

Microwave assisted synthesize of new some benzimidazole derivatives and determination of protonation constant of these compounds in non-aqueous media

A series of 2-substituted benzimidazole derivatives have been synthesized via microwave mediated process. Different benzimidazole derivatives were titrated with tetrabutylammonium hydroxide in four non-aqueous solvents (isopropyl alcohol, N,N-dimethylformamide,tert-butyl alcohol and acetonitrile), using potentiometric method. The half neutralization potential values and the corresponding pKa values were determined for all cases

Evaluation of satisfaction with a questionnaire according to fracture level and fracture type of patients who underwent balloon kyphoplasty

Objective: The aim of this study is to better understand which type of fracture and localization have more painful or worse outcomes for the kyphoplasty procedure. Materials and Methods: Kyphoplasty cases operated between 2013 and 2018 were included in the study. The patients were contacted through the numbers registered in the hospital system. A questionnaire were asked to the patients. Patients were grouped according to gender, fracture level (T12-L1 and others) and fracture type (Osteoporotic, trauma, malignancy, unknown). Results: Fourty-one patients were included in the study. Three-quarters of the patients were women and average age was 62. Ninety-two percent of the patients stated that the pain of the procedure was tolerable. Seventy percent reported that their pain decreased after the procedure and 75% of the patients stated that they could have this procedure done again. Pain reduction and the desire to have same surgery again were significantly higher in female patients than in the male group (p<0.05). In the T12-L1 group and osteoporotic fracture group, the procedure was more easily tolerated, the pain was relieved more and the desire to have the same surgery was higher (p<0.05). Conclusion: Kyphoplasty is accepted as an operation that is well tolerated by patients and has good pain relief. Additionally more detailed information was obtained about the patient’s complaints after the kyphoplasty procedure, according to the fracture level and type.Publisher's Versio

Clinical and radiological results of oxford phase-3 medial unicompartmental knee arthroplasty

PubMed ID: 31832288Purpose The aim of this retrospective study was to investigate the effectiveness of medial unicompartmental knee arthroplasty (UKA) by showing the results of the radiological and clinical outcomes of the patients. Materials and methods Seventy-two knees of 54 patients who underwent UKA between September 2005 and March 2011 for medial knee arthritis with a minimum follow-up of six months were evaluated. Range of motion (ROM), Hospital for Special Surgery (HSS) knee score, Knee Society Score (KSS), and Oxford Knee Score (OKS) were investigated both preoperatively and postoperatively. On the other hand, Oxford radiographic evaluation criteria were used to evaluate prostheses radiologically at the final follow-up. Results The average age was 53.4 years (47 to 79 years). The average follow-up time was 39.8 months (8 to 72 months). There was a significant difference between preoperative and postoperative ROM, HSS, and OKS (p<0.05). Radiologically, there was no sign of arthritis on the unoperated side of the knee or failure of prosthesis detected. Before the operation, the average clinical KSS was 63.2 and improved to 91.4 after the operation. In addition, the average functional KSS was 54.9 before the operation and improved to 86.5 after the operation. The average knee flexion degree was 109.1 before the operation and there was an improvement to 123.6 degrees after the operation. Before the operation, the average HSS score was 67.5 (range, 52 to 75) and improved to 89.9 (range, 85 to 100) at the final control examination. Conclusion This study supports the use of Oxford Phase 3 UKA, which has excellent clinical and radiological results in patients with medial knee arthritis

Evaluation of the biocompatibility of various self-adhesive resin cements on subcutaneous connective tissue: An in vivo study

Background: The purpose of the study was to examine the subcutaneous connective tissue reaction to three self-adhesive resin cements. Methods: Sixty-three polyethylene tubes were filled with three different self-adhesive resin cements (Group Z [Zirconite], Group P [Panavia SA], and Group H [High Q Bond]). Twenty-one polyethylene tubes remained empty and were used as controls (Group C). All tubes were implanted into the subcutaneous tissue of the 21 rats. Specimens from each cement type were obtained at 7, 30, and 90 days. Quantitative assessments of inflammatory cells were performed in 5 different areas of each specimen. Results: All animals survive during the follow-up periods except two rats. The mean values of inflammatory cells at 90 days were 14 (±1.8), 15.1 (±3.5), 96 (±12.1), 16 (±2.1) in Groups C, H, P, and Z, respectively. The thicknesses of the fibrous capsule decreased significantly with time in all groups except Group P. Conclusion: Biocompatibility of self-adhesive resin cements was material-dependent. High Q Bond and Zirconite exhibited satisfactory biocompatibility; however, Panavia demonstrated a moderate inflammatory response at 90 days

Case of Right Hepatic Artery Originated From Superior Mesenteric Artery and Accessory Left Renal Artery

Common hepatic artery, normally is one of the three branches of coeliac trunk, gives off gastroduedonal artery and proper hepatic artery at the upper face of the first part of the duedonum. Renal arteries are two thick arteries which are located just below the mesenteric superior artery and separated by a right angle to the sides of the aorta. 64 year-old male patient with suspected adenocarcinoma of the fundus of the stomach was taken spiral computed upper abdominal CT. Right hepatic artery as a variational is originated from the superior mesenteric artery proximally and left hepatic artery is originated from coeliac trunk. In our case double left renal arteries were observed. Due to growing interventional radiological procedures, transplantation and vascular surgical procedures, variations of the renal arteries and the hepatic arteries are becoming more and more important. This is why patients who undergoing gastrectomy and lymphadenectomy in gastric carcinoma like our patient, a good knowledge of the anatomy and variations of the arteries leaving the abdominal aorta is required

Review on the macro-modeling alternatives and a proposal for modeling coupling beams in tall buildings

Coupling beams between shear walls are one of the key elements for energy dissipation in tall buildings. A representative mathematical model of coupling beam should represent flexure, shear and interface slip/extension mechanisms simultaneously. This goal can be achieved by using either detailed finite element models or by using macro models. This paper presents a review of various macro model alternatives for diagonally reinforced coupling beams in the literature. Three distinct methods have been reviewed in terms of their modeling techniques, the cyclic response overlap and the amount of cumulative plastic energy dissipated based on the results of previously performed tests. Through an analytical study, adequately accurate results can be captured by using macro models, although they are simpler in practice compared to sophisticated micro models. This study shows that, by modifying ultimate shear capacities where concrete material between diagonal bundles is adequately confined, it is possible to capture a more realistic result and a better approximation to the actual responses. It is also concluded that a simpler numerical model for diagonally reinforced coupling beams can be achieved by introducing linear part of slip/extension behavior into elastic part of the beam. It is observed, as a result of this study, that the ratio of effective stiffness to that of the gross cross-sectional one ranges from 0.04 to 0.14 in diagonally reinforced coupling beams depending on the aspect ratio and the beam strength parameters
