Abstract

The present work aims to establish relationships between shoreline historical variations (close to the river mouths) and slope dynamics on mountain and hilly areas: these are considered as fundamental physiographic units of the Adriatic central Italy. The study deals about the deltaic system of the Chienti river, which is representative of the deltaic systems of the main Marchean rivers. Goal is to recognize possible geomorphological indicators of climatic variations during late Holocene. Debris flows on the Sibillini Mts were analysed and interpreted. Their activation can be associated with: late Pleistocene-early Holocene deglaciation, with regard to the oldest phenomena; agricultural, forestry and grazing activities during the Late Middle Ages, even though evidence of climatic conditioning is also present. Moreover, some important landslide phenomena on the high hilly areas were examined: historical data demonstrated an intense post-Middle Age activity (XVth-XVIIIth centuries) related to the strong rainfall increase as a consequence of climatic worsening.

Abstract

Minimally invasive video-assisted parathyroidectomy (MIVAP) was introduced in 1997 for the treatment of sporadic primary hyperparathyroidism (sPHPT). The study aim was to review the entire series of patients operated on in order to analyse the learning curve of this procedure.Between February 1997 to January 2001, 185 patients underwent MIVAP. All these patients were divided into three groups: group A (GA) included 63 patients operated on between February 1997 and September 1998; group B (GB) 64 patients operated on between October 1998 and January 2000; Group C (GC) 64 patients operated on between January 2000 and January 2001. Mean operative time, complications and conversions rates of the three groups were compared.The three groups were well matched for age and gender. Mean operative time was significantly shorter in patients of GC (28.3 +/- 13.6 min) when compared with GA (62.3 +/- 24.6 min) and GB (48.4 +/- 18.1 min). Conversion was required in 3 cases of GA (4.8%), in 8 cases of GB (12.8%) and in 4 cases of GC (6.5%). One transient postoperative recurrent nerve palsy and 4 cases of transient postoperative hypocalcemia were observed among patients of GA. No complications were registered in the other groups.This study shows that with increasing experience, the operative time of MIVAP was dramatically reduced, as well as postoperative complications rate. The higher percentage of conversion in groups B and C may be explained by the fact that, with increasing experience, more difficult and ambiguous cases were operated with this technique.

Abstract

The authors present the results of the analysis of mortality statistics among the children who were born in 1977 in the French department of Hauts-de-Seine. The data were obtained from 8th day of life health certificates, from information given by the registry office and from hospital records. The results establish the department in an excellent position: child mortality rate: 7.34%, early neonatal mortality: 2.81%, late neonatal mortality 1.45% and post-neonatal mortality: 3.08%. The causes for child mortality are analysed and suggestions concerning possible improvements are made.
