Muscle Activity Asymmetry of The Lower Limbs During Sprinting in Elite Soccer Players.

The analysis of movement patterns through EMG activity provides the opportunity to identify the muscle groups most involved in a particular exercise, and to determine the scope of inter-limb deficiencies. The aim of the present study was to investigate the effects of a side-to-side muscle activity asymmetry between the left and the right lower limb during sprinting in soccer players. Sixteen professional soccer players took part in the study.

[Pterygium--menace, lying in wait].

Pterygium consists of epithelium of bulbar conjunctiva and hypertrophied subconjunctival connective tissue. Although described and recognized before 1000 B. C, its pathogenesis still remains an ophthalmic enigma.

[Corneal astigmatism after tunnel incision for cataract extraction].

Purpose: To evaluate the development of astigmatism after cataract extraction depending on the kind of incision

Material And Methods: Astigmatism was examined in 107 eyes of 92 patients, who underwent cataract extraction, mostly with IOL's implantation. In 52 eyes phacoemulsification with tunnel incision, measuring 5 mm in 27 and 8 mm in 25, was performed. In the control group of 55 eyes incision with scleral flap measured 2/5 of the corneal circumference.

[Intraoperative prevention of bleeding into the anterior chamber in hemorrhagic glaucoma using viscoelastic substances].

The anterior chamber tamponade with Healon and 2.5% solution of hydroxymethyl-cellulose has been applied in 10 patients, aged 9-65 years, during antiglaucomatous surgery connected with interscleral dislocation of iris. The tamponade prevented the rupture of blood vessels of iris.

[Organization and the results of surgical treatment of cataract with implantation of artificial lenses in ambulatory conditions].

Forty one patients aged 29 to 82 years were subjected to cataract extraction in ambulatory conditions. Fifty eyes were operated, among them 33 with implantation of a posterior chamber artificial lens. In cases of a lack of opacities in the cortex layers their structure was loosened before the operation by a YAG laser.
