Solution of Massless Spin One Wave Equation in Robertson-Walker Space-time

We generalize the quantum spinor wave equation for photon into the curved space-time and discuss the solutions of this equation in Robertson-Walker space-time and compare them with the solution of the Maxwell equations in the same space-time.Comment: 16 Pages, Latex, no figures, An expanded version of paper published in International Journal of Modern Physics A, 17 (2002) 113

Coherent States for Tremblay-Turbiner-Winternitz Potential

In this study, we construct the coherent states for a particle in the Tremblay-Turbiner-Winternitz potential by finding the conserved charge coherent states of the four harmonic oscillators in the polar coordinates. We also derive the energy eigenstates of the potential and show that the center of the coherent states follow the classical orbits of the particle

Concomitant SLAP repair does not influence the surgical outcome for arthroscopic Bankart repair of traumatic shoulder dislocations

Background: Prior studies revealed the presence of superior labrum anterior-to-posterior (SLAP) injury together with Bankart lesions in some patients. The purpose of the study is to compare the clinical results of isolated Bankart repairs with the clinical results of Bankart repairs when performed with concomitant SLAP repairs. Methods: The patients who underwent arthroscopic surgery for treatment of anterior glenohumeral instability were evaluated retrospectively. Group 1 consisted of 19 patients who had arthroscopic SLAP repair together with Bankart repair. The mean age of the patients was 23. Group 2 consisted of 38 patients who underwent isolated Bankart repair. The mean age was 24. Knotless anchors were used in both groups. Results: The mean follow-up was 34 months (range: 26-72). In group 1, the mean preoperative Constant score was 84 (range: 74-90, standard deviation (SD): 5.91) and Rowe score was 64.1 (range: 40-70, SD: 8.14). In group 2, the preoperative Constant score was 84.4 (range: 70-96, SD: 5.88) and Rowe score was 60 (range: 45-70, SD: 7.95). In group 1, the postoperative mean Constant score raised to 96.8 (range: 88-100, SD: 2.91) and the mean Rowe score raised to 92.3 (range: 85-100, SD: 5.17). In group 2, the postoperative mean Constant score was 94.9 (range: 88-100, SD: 3.70) and the mean Rowe score was 94.2 (range: 80-100, SD: 4.71). The difference between the scores of two groups was insignificant (p > 0.05). When the numbers of redislocations and range of motion were compared, no significant difference was found (p > 0.05). Conclusion: Accompanying SLAP repair in surgical treatment with Bankart repair for shoulder instability does not affect the results negatively. Properly repaired labral tears extending from anterior inferior to the posterior superior of the glenoid in instability treatment have the same outcome in overall results as repaired isolated Bankart lesions

Richter's transformation presenting with superior vena cava syndrome

In the present study, we report a 65-year old man who had been diagnosed earlier as having chronic lymphocytic leukemia and treated for 2 years with fludarabine. He presented to our hospital 2 years later with clinical features of superior vena cava syndrome. The underlying cause was diffuse large B cell lymphoma obstructing the superior vena cava

The Changed Route of Anterior Tibial Artery due to Healed Fracture

We would like to highlight unusual sequelae of healed distal third diaphyseal tibia fracture that was treated conservatively 36 years ago, in which we incidentally detected peripheral CT angiography. The anterior tibial artery was enveloped three-quarterly by the healing callus of the bone (distal tibia)

Incidence of Autoimmune Thyroid Disease in Patients with Type 1 Diabetes

INTRODUCTION: In this study, it was aimed to determine the frequency of autoimmune thyroid disease (OITH) in children and adolescent patients who were followed-up with type 1 diabetes mellitus(T1DM) and to evaluate its relationship with other parameters
