STUDY DESIGN This study determined the relative efficacy of somatosensory-evoked potentials and motor-evoked potentials in monitoring spinal cord function during surgery for patients with idiopathic versus neuromuscular scoliosis. OBJECTIVES To determine whether patients with idiopathic versus neuromuscular scoliosis demonstrate significantly different(More)
STUDY DESIGN This study investigated the use of mechanically elicited electromyograms during the placement of pedicle screws in 89 patients undergoing surgery for spinal stenosis. SUMMARY OF BACKGROUND DATA Several methods for monitoring nerve roots are available. However, mechanically elicited electromyograms may be more sensitive to mechanical(More)
BACKGROUND This report describes the technique and early results of a simple outpatient laparoscopic ventral hernia repair. METHODS Data were gathered prospectively for all laparoscopic ventral hernia repairs from January 1996 to December 1997 at a 228-bed hospital. Prolene mesh was stapled to the peritoneal surface of the abdominal wall, leaving sac in(More)
Nonlinear chemical medium can be used to perform information processing functions. In typical applications information is coded in excitation pulses and required operations are performed by interaction of pulses forced by intentionally introduced geometrical structure of the medium. Here we describe a structured system that seems promising for information(More)
We use experimental results to estimate the values of parameters of simple models describing the time evolution of the Belousov-Zhabotinsky reaction proceeding in droplets surrounded by hydrocarbons. The equations with fitted parameters correctly describe the period of oscillations for a large class of experimental conditions at which the reaction is(More)
This study attempts to determine by independent review the results of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair for hernias with increased risk for recurrence. Indicators used for increased recurrence risk were recurrent hernias or simultaneously repaired bilateral inguinal hernias. Office and hospital records of all such(More)
This deliverable complements the link to experimental results and differential equation models from ICFPAN that were missing in deliverable D3.1. Abstract Here we review and extend models on different scales for a computing architecture made from networks of excitable chemical droplets. The model system of the Belousov-Zhabotinsky (BZ) reaction enclosed in(More)
Lipid covered droplets containing solution of reagents of oscilla-tory Belousov-Zhabotinsky reaction and surrounded by hydrocarbons form an interesting system for studying information processing operations that can be directly executed by a chemical medium. Activa-1 tions are transmitted between droplets in contact so the ensemble of droplets can be(More)
Cooperation plays the crucial role in shared space of the homecare processes. It is a rather hard task to ensure effective cooperation in home care environment. This is due to variability of schedules, tasks and mobility of both patients and carers. In this paper, we discuss sensor network technology that can facilitate and improve home care cooperation(More)
