| 1 | Displacement Trends of Slow-moving Landslides: Classification and Forecasting显示文摘A framework is proposed to characterize and forecast the displacement trends of slow-moving landslides, defined as the reactivation stage of phenomena in rocks or fine-grained soils, with movements localized along one or several existing shear surfaces. The framework is developed based on a thorough analysis of the scientific literature and with reference to significant reported case studies for which a consistent dataset of continuous displacement measurements is available. Three distinct trends of movement are defined to characterize the kinematic behavior of the active stages of slow-moving landslides in a velocity-time plot: a linear trend-type I, which is appropriate for stationary phenomena; a convex shaped trend-type II, which is associated with rapid increases in pore water pressure due to rainfall, followed by a slow decrease in the groundwater level with time; and a concave shaped trend-type III, which denotes a non-stationary process related to the presence of new boundary conditions such as those associated with the development of a newly formed local slip surface that connects with the main existing slip surface. Within the proposed framework, a model is developed to forecast future displacements for active stages of trend-type II based on displacement measurements at the beginning of the stage. The proposed model is validated by application to two case studies. | CASCINI Leonardo CALVELLO Michele GRIMALDI Giuseppe Maria | 2014 | Journal of Mountain Science2014，11，3： | 7 |
| 2 | Long-term outcome of pancreatic function following oncological surgery in children:Institutional experience and review of the literature显示文摘BACKGROUND Pancreatic neoplasms are uncommon in children and in most cases they are benign or have low malignant potential.Pancreatoblastoma and solid pseudopapillary tumor are the most frequent types in early and late childhood,respectively.Complete resection,although burdened by severe complications,is the only curative treatment for these diseases.Pancreatic surgery may result in impaired exocrine and endocrine pancreatic function.However,limited data are available on the long-term pediatric pancreatic function following surgical resection.AIM To investigate endocrine and exocrine pancreatic function and growth after oncological pancreatic surgery in a pediatric series.METHODS A retrospective analysis of all pediatric patients who underwent surgery for pancreatic neoplasm in our Institution from January 31,2002 to the present was performed.Endocrine and exocrine insufficiency,auxological and fat-soluble vitamin status(A,D,E and clotting tests)were assessed at diagnosis and at every follow-up visit.Exocrine insufficiency was defined as steatorrhea with fecal elastase-1<200μg/g stool,while endocrine insufficiency was identified as onset of Diabetes or Impaired Glucose Tolerance.Growth was evaluated based on body mass index(BMI)z-score trend.RESULTS Sixteen patients(12 girls and 4 boys,mean age 10.7±5.3 years),were included.Nine patients(56%)had a neoplasm in the pancreatic head,4 in the body/tail,2 in the tail and 1 in the body.Histological findings were as follows:Solid pseudopapillary tumor in 10 patients(62.5%),insulinoma in 2 patients,neuroendocrine tumor in 2 patients and acinar cell carcinoma in 2 patients.The most frequent surgery was pancreaticoduodenectomy(50%).Exocrine failure occurred in 4 patients(25%)and endocrine failure in 2 patients(12.5%).Exocrine insufficiency occurred early(within 6 mo after surgery)and endocrine insufficiency later(8 and 10 years after surgery).Mean BMI z-score was 0.36±1.1 at diagnosis and 0.27±0.95 at the last assessment.Vitamin D was insufficient(<30 ng/mL)in 8 of the 16 patients during the follow-up period.Vitamins A,E and clotting test were into the normal ranges in all patients.CONCLUSION Careful and long-term monitoring should follow any pancreatic surgery,to recognize and promptly treat exocrine and endocrine pancreatic insufficiency,which can occur after surgery. | Giulia Bolasco Teresa Capriati Chiara Grimaldi Lidia Monti Maria Debora De Pasquale Ippolita Patrizia Patera Marco Spada Giuseppe Maggiore Antonella Diamanti | 2021 | World Journal of Clinical Cases2021，9，25： | 2 |
