Introduction:Elbow epicondylar tendinitis is a common problem for patients whose activities require strong gripping or repetitive wrist movements in the day-to-day activities of life. Histologic specimens from chronic cases confirm that tendinitis is not an acute inflammatory condition but rather a failure of the normal tendon repair mechanism associated with angiofibroblastic degeneration. Tendon regeneration may be improved by injecting autologous growth factors obtained from the patient's own blood. Autologous growth factors can be injected with autologous whole blood or platelet-rich plasma (PRP).Materials and Methods:A randomized study with 83 patients was done. The study population comprised two groups. Group A (n = 50) treated with local steroid injection and Group B (n = 33) treated with autologous PRP. Patients were allocated randomly using computer-generated random number table. The base-line evaluation was done using visual analog score (VAS) and modified Mayo performance index for elbow (MAYO). Re-evaluation was after 1, 2, and 6 months of the procedure. Statistical analysis was done using independent t-test.Results:Six months after treatment with PRP, patient's with elbow epicondylitis had a significant improvement in their VAS (P < 0.05) and MAYO (P < 0.05) in contrast to steroid, whereas no statistical difference was found between the two groups at 1 and 2 months after intervention.Conclusion:Treatment of patients with epicondylitis with PRP reduces pain and significantly increases function, exceeding the effect of corticosteroid injection.

In the past decade, a number of image encryption algorithms based on chaotic maps have been proposed. Recently, an image encryption algorithm based on chaotic map lattice (CML) is proposed that allows direct encryption and decryption of color digital images. In this paper, we propose an enhanced CML based algorithm for image encryption to improve the security of the algorithm. The performance of the proposed algorithm is analyzed through computer simulations. It is shown that the enhanced algorithm successfully and completely encrypts the color images and provides more distortion to the plainimages than previously proposed CML based algorithm for the same set of parameters. It is also shown that the proposed algorithm is more sensitive to a small change in plainimages, number of iterations and number of cycles. This makes the proposed algorithm more efficient and improves the level of security provided by the algorithm.

Spinoglenoid cyst (SGC) is a ganglion arising in the spinoglenoid notch and is thought to be related to SLAP lesion. This cyst often compresses the suprascapular nerve in the spinoglenoid notch. Symptomatic cysts require surgical treatment when conservative treatment fails. In particular, arthroscopic decompression through the torn labral tissue when the cyst is extending into the joint cavity is easy and convenient. However, if the cyst is confined to the spinoglenoid notch, arthroscopic approach through the torn labral tissue is challenging. Thus, we present our preferred technique of addressing the SGC through an additional superior capsular window after completing SLAP repair. We believe that our technique is easy, reproducible, and reasonable.
