Sounds and silence: an optical topography study of language recognition at birth.
Does the neonate's brain have left hemisphere (LH) dominance for speech? Twelve full-term neonates participated in an optical topography study designed to assess whether the neonate brain responds specifically to linguistic stimuli. Participants were tested with normal infant-directed speech, with the same utterances played in reverse and without auditory stimulation. We used a 24-channel optical topography device to assess changes in the concentration of total hemoglobin in response to auditory stimulation in 12 areas of the right hemisphere and 12 areas of the LH. We found that LH temporal areas showed significantly more activation when infants were exposed to normal speech than to backward speech or silence. We conclude that neonates are born with an LH superiority to process specific properties of speech.

[Catheter placement for peritoneal dialysis using videoendoscopy].
From December 1993 to December 2000 at the Department of Surgery, General Hospital "Sveti Duh", and University, Hospitals Split and Osijek the catheter for peritoneal dialysis was placed in 128 patients, in 137 cases. Videoendoscopic procedure, with the trocar made precisely for that purpose, was used. All surgical procedures, performed in the completely equipped operation room and in general anesthesia, were done without any intraoperative or postoperative complications. The procedure showed to have all advantages of endoscopic or minimally invasive surgery. The patients recovered quickly with low consumption of analgesics, got out of the bed and started with feeding sooner. There were no wound complications. It was possible to start with the dialysis 2-3 days after the procedure. Most important, the results showed that using this approach in comparison to others, there were no more dialysis solution leakages, catheter drainage problems, or more tunnel, exit site or peritoneal infections. Along with placing the catheter, other surgical procedures could be also done without increasing the complication rate. Therefore, laparoscopic cholecystectomy was done in 12 cases, adhesiolysis in 25 cases, and right adnexectomy, open hernioplasty and umbilical hernioplasty in one case. Videoendoscopic approach of placing the catheter is a simple, short and patient convenient procedure, with quick recovery and without any increase in complication rate.
