Solid-pseudopapillary tumor of the pancreas: A single center experience
open6noAim of this study was to review the institutional experience of solid-pseudopapillary tumors of the pancreas with particular attention to the problems of preoperative diagnosis and treatment. From 1997 to 2013, SPT was diagnosed in 18 patients among 451 pancreatic cystic neoplasms (3.7%). All patients underwent preoperative abdominal ultrasound, computed assisted tomography, and tumor markers (CEA and CA 19-9) determinations. In some instances, magnetic resonance, positron emission tomography, and endoscopic ultrasound with aspiration cytology were performed. There were two males and 16 females. Serum CA 19-9 was slightly elevated in one case. Preoperative diagnosis was neuroendocrine tumor (n = 2), mucinous tumor (n = 2), and SPT (n = 14). Two patients underwent previous operation before referral to our department: one explorative laparotomy and one enucleation of SPT resulting in surgical margins involvement. All patients underwent pancreatic resection associated with portal vein resection (n = 1) or liver metastases (n = 1). One patient died of metastatic disease, 77 months after operation, and 17 are alive and free with a median survival time of 81.5 months (range 36-228 months). Most of SPT can be diagnosed by CT or MRI, and the role of other diagnostic tools is very limited. We lack sufficient information regarding clinicopathologic features predicting prognosis. Caution is needed when performing limited resection, and long and careful follow-up is required for all patients after surgery.openBeltrame, Valentina; Pozza, Gioia; Dalla Bona, Enrico; Fantin, Alberto; Valmasoni, Michele; Sperti, CosimoBeltrame, Valentina; Pozza, Gioia; DALLA BONA, Enrico; Fantin, Alberto; Valmasoni, Michele; Sperti, Cosim

Giant leiomyoma of the gastroesophageal junction: technique and results of endoscopic full-thickness resection
Four consecutive patients with a giant leiomyoma originating from the posterior aspect of the gastroesophageal junction were treated with full-thickness endoscopic retroflex dissection. A complete removal of the lesion was obtained in all cases. No complications were observed except for some degree of air filtration causing symptomatic pneumoperitoneum in one patient. Retroflex endoscopic full-thickness resection of giant leiomyoma at the gastroesophageal junction is feasible and safe

Biomonitoring with macroinvertebrate communities in Italy: what happened to our past and what is the future?
Flow intermittency negatively affects three phylogenetically related shredder stoneflies by reducing CPOM availability in recently intermittent Alpine streams in SW-Italian Alps
Acción protectora del régimen especial de trabajadores autónomos
El estudio de la mejor manera posible cómo el RETA otorga la acción protectora ante las diversas cuestiones y posibles contingencias que se pueden plantear en las diferentes etapas de la vida de un trabajador autónomo.Se realiza un acercamiento al ámbito de aplicación subjetivo del RETA, qué sujetos están incluidos y cuáles están excluidos. Una vez concluido el análisis sobre el ámbito de aplicación subjetivo, se pasa a analizar la acción protectora desgajando cada una de sus intervenciones para realizar un gran mapa sobre la acción protectora en el RETA, resaltando las diferencias existentes entre esta y aquella que disfrutan los trabajadores por cuenta ajena del régimen general.<br /
