The impact of prenatal sonographic diagnosis of oesophageal and gastrointestinal obstructions has been analysed over a 10-year period. Three groups of patients were evaluated. The first group consisted of 46 newborns with abnormal prenatal sonogratns, 41 of which were confirmed to have intestinal obstruction postnatally. The second group consisted of 17 neonates with normal prenatal sonograms who had intestinal obstruction postnatally. The third group included 56 newborns who did not undergo a prenatal sonogram but who had intestinal obstruction confirmed at surgery. Polyhydramnios without the appearance of a stomach on ultrasound was diagnostic of pure oesophageal atresia. Polyhydramnios with intestinal dilation was diagnostic of intestinal obstruction. Although surgery was performed earlier in the infants diagnosed prenatally with ultrasound, mortality was no less than in the group that did not undergo a prenatal sonogram, probably because of the high incidence of associated anomalies. 相似文献

Mapping and quantifying habitat fragmentation in small coastal areas: a case study of three protected wetlands in Apulia (Italy) 总被引:1,自引:0,他引:1
In the Mediterranean Region, habitat loss and fragmentation severely affect coastal wetlands, due to the rapid expansion of
anthropogenic activities that has occurred in the last decades. Landscape metrics are commonly used to define landscape patterns
and to evaluate fragmentation processes. This investigation focuses on the performance of a set of landscape pattern indices
within landscapes characterized by coastal environments and extent below 1,000 ha. The aim is to assess the degree of habitat
fragmentation for the monitoring of protected areas and to learn whether values of landscape metrics can characterize fine-resolution
landscape patterns. The study areas are three coastal wetlands belonging to the Natura 2000 network and sited on the Adriatic
side of Apulia (Southern Italy). The Habitat Maps were derived from the Vegetation Maps generated integrating phytosociological
relevés and Earth Observation data. In the three sites, a total of 16 habitat types were detected. A selected set of landscape
metrics was applied in order to investigate their performance in assessing fragmentation and spatial patterns of habitats.
The final results showed that the most significant landscape patterns are related to highly specialized habitat types closely
linked to coastal environments. In interpreting the landscape patterns of these highly specialized habitats, some specific
ecological factors were taken into account. The shape indices were the most useful in assessing the degree of fragmentation
of habitat types that usually have elongated morphology along the shoreline or the coastal lagoons. In all the cases, to be
meaningful, data obtained from the application of the selected indices were jointly assessed, especially at the class level. 相似文献
