Specific features of electrochemical dissolving of 12X18H9T stainless steel, OT-4 titanium alloy and BK8 hard alloy in the sodium nitrate water solution exposed to 1.06 micrometer wavelength laser irradiation are considered. It is found that the main mechanism of activating the dissolving process is to increase the reactivity of the electrolyte by stepwise photoactivation.

The authors suggest the original conception of the development of so-called tibial syndrome that is the typical one for patients with infantile cerebral paralysis. The significance of tibial synkinesis being pathognomonic for pyramidal lesions in the formation of a peculiar severe locomotor pathology is detected. This severe locomotor pathology is a tibial syndrome. The authors emphasize that tibial syndrome is often a failured outcome of surgical intervention for foot equinus in young children. New surgical technique that eliminates the main pathologic components of tibial syndrome: flexion contracture of the knee joint, crus anterversion, redundant dorsal foot flexion, and improves the posture and gait is suggested.
