[Thoracotomy and thoracoscopy in the treatment of patent arterial duct in infants weighing less than 2500 g].

Background: Thoracoscopic clipping of the patent ductus arteriosus is an alternative to conventional surgical closure via thoracotomy in low birth weight infants. The aim of this study is to compare of these two groups of patients for the last 11 years.

Methods: We reported the data of 127 small children's who underwent standard transaxillary thoracotomy (101 patients - Group I) and video-assisted thoracoscopic surgery for patent ductus arteriosus clipping (26 patients - Group II).

[Hybrid surgery for the treatment of ovarial cysts in newborns].

The aim of this study was to evaluate the effect of hybrid technology (laparoscopy and open surgery) for treatment of ovarian cysts in small babies and infants. Between January 2002 and November 2012, we have performed 11 operation for neonatal ovarian cysts repaired through standard circumumbilical incision (Group I) and 16 operation with using combined hybrid laparoscopic-assisted technique (Group II). The circumumbilical incision utilized at our institution is a classic Bianchi procedure.

A metabolic aspect of high myopia.

Abnormal zinc and copper metabolism has been described in some retinal disorders affecting the retinal pigment epithelium. Anatomic studies in high myopic eyes, show important changes in this retinal layer. We examined the blood for zinc and copper and urine for copper in different groups of high myopic black and white patients, and high myopic white patients with primary retinal detachment.
