These data support mediastinal cyst excision as a suitable indication for larger children. Currently, there is a lack of evidence that lower weight children, and particularly neonates, are good candidates for RATS.

Cautious adjustments in the patient positioning and trocar placement were necessary in a subset of this pediatric population. For these three particular procedures, with the exception of the longer set up time, the results between the two groups were comparable. These data support the feasibility of robotic-assisted surgery for small children, despite the lack of dedicated instruments.

Adjunctive computerized simulation accelerates the learning curve of basic CCE in improving practical and technical skills and reduces the number of TTE examinations required to reach competency.

Abstract:In the context of climate change, agricultural managers have the imperative to combine sufficient productivity with durability of the resources. Many studies have shown the interest of recent satellite missions as suitable tools for agricultural surveys. Nevertheless, they are not predictive methods. A system able to detect summer crops as early as possible is important in order to obtain valuable information for a better water management strategy. The detection of summer crops before the beginning of the irrigation period is therefore our objective. The study area is located near Toulouse (southwestern France), and is a region of mixed farming with a wide variety of irrigated and non-irrigated crops. Using the reference data for the years concerned, a set of fixed thresholds are applied to a vegetation index (the Normalized Difference Vegetation Index, NDVI) for each agricultural season of multi-spectral satellite optical imagery acquired at decametric spatial resolutions from 2006 to 2013. The performance (i.e., accuracy) is contrasted according to the agricultural practices, the development states of the different crops and the number of acquisition dates (one to three in the results presented here). The detection of summer crops reaches 64% to 88% with a single date, 80% to 88% with two dates and 90% to 99% with three dates. The robustness of this method is tested for several years (showing an impact of meteorological conditions on the actual choice of images), several sensors and several resolutions.

In light of the better performances with 8 mm tools for specific tasks and parietal sparing constraints in restricted spaces, this study indicates that 5 mm instruments can be deemed to be less effective for reconstructive procedures in small children.
