RESUMO
The mismatch negativity component of auditory event-related potentials was studied in fulI-term infants of the first month of life and adults. Acoustic stimuli with large deviance in passive oddball task were used. Research data revealed distinctive features in morphology and specificity in parameters of positive mismatch component in children at early ages. Contrary to results from adult group infant component was manifested in two positive peaks, greater amplitude and longer latency. A significant positive correlation was observed between infant's conceptual age and amplitude, and significant negative correlation was found between gestation age and latency for this positive component. Results allowed proposing specificity in parameters of infant's positive mismatch component indicated proceeding maturational changes in auditory cortex at early ages.

79 patients with the acute primary non-obstructive pyelonephritis were treated during 2003-2006. 24 (30.3%) patients were operated on with the diagnosis of acute primary purulent destructive pyelonephritis. Organopreserving operations were performed in 23 (95.8%) of patients. The early diagnostics of purulent destructive complications of pyelonephritis, using the developed diagnostic algorithm, and modified operative technique allowed to increase the rate of organopreserving operations, avoid reinterventions and decrease the risk of intraoperative complications.
