[Prognostication of the results of treatment of retinal detachment with silicone oil tamponade using pattern recognition methods].

The aim of this work was to solve the problem of prognostification of anatomic and functional results of treatment of retinal detachment (RD) with silicone oil tamponade. Analysis of the treatment of 257 eyes was performed using pattern recognition methods. All the patients were characterized according to 32 signs related the preoperative status only.

[A spectral analysis of the periodic components in the heart rhythm structure of newborn infants].

Spectral analysis of spontaneous heart rate fluctuations were assessed in 12 healthy newborn infants and in 14 low birth weight newborns. The orthostatic test was performed by the change of newborns posture. High-frequency fluctuations at the respiratory rate were detected in healthy infants and orthostatic reactions of heart rate resembled the same reactions in healthy adults.
