[Light optical and ultrastructural characteristics of human focal cortical dysplasias].

Focal cortical dysplasias (FCD) are one of the most common causes of drug-resistant epilepsy. Morphological changes in the focal cortical dysplasia tissues obtained from epileptic patients during surgical interventions were analyzed. Eleven specimens of the cerebral cortex with FCD areas were explored.

[Endovascular laser ablation with wavelength 1,560 nm for varicose veins].

In 2002 - 2008 more than 1000 patients with lower limb varicose veins were treated with endovenous laser coagulation (EVLC) of subcutaneous and perforating veins in the Therapeutic Rehabilitation Center. Usually we used laser wavelength between 915 and 980 nm; but recently 1,560-nm laser, which physical properties are quite different, was used for 43 patients, including 49 EVLCs for great (GSV) and lesser (LSV) saphenous veins and 15 EVLCs for perforating veins (PV). Interventional technique was similar to previously used.
