The formation of oxide semiconductor films of the (Mn,Co,Cu)O type by radio frequency magnetron sputtering is presented. The conditions of deposition and subsequent heat treatment make it possible to obtain films with electrophysical characteristics close to those of the bulk ceramic materials used as a target for magnetron sputtering. Two variants of thermistor geometry were implemented.

Also available, however less often used, is a laparoscopic technique for low-profile gastrostomy tube (button) placement. In this study we compare the pre-, intra-, and post-procedural outcomes of each technique.

View Article and Find Full Text PDFThermal explosion problem for a medium with oscillating ambient temperature at its boundaries is considered. This is a new problem in thermal explosion theory, not previously considered in a distributed system formulation, but important for combustion and fire science. It describes autoignition of wide range of fires (such as but not limited to piles of biosolids and other organic matter; storages of munitions, explosives, propellants) subjected to temperature variations, such as seasonal or day/night variation.

Aim: To compare treatment of intestinal malrotation in newborns and infants using laparoscopy and laparotomy.
Material And Methods: For the period from January 2004 to December 2013 34 Ladd's procedures were performed. Children were divided into 2 groups by 17 patients: laparoscopic (group I) and open treatment (group II).

Aim: To demonstrate training curves for endosurgical interventions in neonates and infants.
Material And Methods: It was analyzed duration of thoracoscopic reconstruction of esophageal atresia (31 patients) and laparoscopic Nissen fundoplication (61 patients) performed for the period from January 2005 to December 2012. Graphs and tables reflecting correlation between duration and number of operations were framed.

Background: Laparoscopic gastrostomy is a widely used interventional procedure in pediatric surgery. We report comparative data for two endosurgical methods for the fixation of the stomach against the abdominal wall, using the U-stitches technique and the Saf-T-Pexy® (Halyard Health Inc., Alpharetta, GA) system.

Purpose: The aim of this study was the comparison of single-port and multiport laparoscopic methods for the treatment of inguinal hernia in children during the first 3 months of life.
Subjects And Methods: Between January 2002 and December 2012, we performed 260 laparoscopic operations in neonates and infants with the diagnosis of inguinal hernia. Surgical procedures were single-port endoscopic herniorraphy (Group I; 180 patients) and multiport laparoscopic herniorraphy (Group II; 80 patients).
For the period January 2002 to December 2013 it was performed 84 interventions for introduction of gastrostomy tube. The first group included 24 open operations and the second group had 60 laparoscopic operations by using of button devices MIC-KEY (Kimberly-Clark, Roswell, USA) in neonates and infants. Statistically significant difference was not observed during comparison of demographic data of patients.

Purpose: Thoracoscopic plication of the diaphragm is an alternative to conventional surgical treatment of diaphragmatic evisceration via thoracotomy in neonates and infants. The aim of this study is to compare results of treatment by these two methods in the past 11 years.
Materials And Methods: We studied the data of 35 neonates who underwent standard posterolateral thoracotomy (18 patients; Group I) or video-assisted thoracoscopic surgery (17 patients; Group II) for diaphragmatic plication.
The aim of this investigation is evidence of opportunity of single laparoscopic approach using during operations in newborns and infants. The authors have an experience of 274 single-port operations performed from January 2009 to December 2013. Success of single laparoscopic approach has been demonstrated in patients with inguinal hernia, congenital hypertrophic pyloric stenosis, feeding violations, ovarian cyst and multi-cystic kidney dysplasia.

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).
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.

Unlabelled: In spite of the appearance of new instruments, equipment, and new surgical techniques, the amount of laparoscopic procedures in newborns and infants remains limited. Nevertheless, some advantages of the laparoscopic nephrectomy technique in infants, which we present in this article allow us to recommend this approach as the method of choice in some renal pathologies in infants and newborns.
Materials And Methods: During the last 2 years of using laparoscopy, we removed 9 multicystic dysplastic kidneys.

The authors analyze results of the investigation of hemodynamics in the abdominal cavity vessels by the method of duplex scanning in 30 patients with acute cholecystitis, in 30 patients with mechanical jaundice and cholelithiasis and in 30 healthy subjects. It was found that these patients had less blood flow along the upper mesenterial artery and the portal vein. As a compensation the blood flow increased along the hepatic artery.
