Objective Evaluation of the efficacy of pancreatic resections for the treatment of chronic pains during chronic pancreatitis. Methods Retrospective study of inpatients for chronic pancreatitis between 1982 to 2000. purpose of admission, morphological changes, treatments and results were evaluated. Results 142 patients were admitted for chronic pancreatitis. 111 patients suffered from chronic pains, due to morphological changes such as pseudocysts, inflammatory masses in the head, dilated pancreatic ducts, biliary or duodenal compressions. Denervations were never efficient, pancreatic resections achieved relief of pain in up to 75% of cases and drainages were efficient in 52% of cases. Conclusions pancreatic resections during chronic pancreatitis s eem to be the most efficient treatment of chronic pains. New techniques such as duodenum-preserving head resection or total pancreatectomy with islet autotransplantation should improve these results.

目的:验证同种异体移植瓣膜(VA)钙化起因于有骨调节蛋白表达的骨化过程的假说。方法:对被移植用于治疗心脏瓣膜功能障碍的15例VA进行研究。将VA与正常主动脉瓣膜(n=20)进行分析比较。结果:所有VA(5例主动脉瓣、10例肺动脉瓣)出现重度钙化和纤维化。免疫组织化学研究显示基质细胞表达骨特异性转录因子Cbfa-1。钙化区域有骨碱性磷酸酶表达。VA的平滑肌(α-SM)肌动蛋白免疫染色多于正常瓣膜,其中有6例VA瓣膜在钙化性结节附近形成细胞簇。

In the Saloum region of central-western Senegal, water needs are essentially met by tapping an underground aquifer associated with the sandy-clay formations of the Continental Terminal, in contact with both the ocean to the west and the highly saline waters of the Saloum River to the north. In this estuarine and deltaic zone with its very low relief, the hydraulic loads in the water tables are generally close to zero or even negative, creating a reversal of the natural flow and encouraging saline intrusion into this system, which makes it very vulnerable. This study concerns the implementation of a numerical model of saline intrusion to provide a better understanding of the vulnerability of the water table by analyzing the variability of the freshwater/saltwater interface. The Modflow-2005 code is used to simulate saline intrusion using the SWI2 module, coupled with the GRASS (Geographic Resources Analysis Support System) software under the Linux operating system with the steep interface approach. The probable expansion of the wedge is studied in three scenarios, taking into account its position relative to the bedrock at 1 m, 5 m and 10 m. Simulations carried out under imposed potential and river conditions, based on variations in groundwater reserves using two effective porosity values, 10−1 and 10−2, show that the water table is highly vulnerable in the northwest sector. The probable expansion of the wedge increases as the storage coefficient decreases and is more marked with river conditions in the areas surrounding the Saloum River, reaching 6 km with a probability of 1. The probability of the wedge reaching a certain degree of expansion decreases from 1 to 0.5, and then cancels out as it moves inland. The probable position of the wedge is limited to 500 m or even 1 km depending on the corner around the coast to the southwest and in the southern zone. This modelling, carried out under natural conditions, will be developed further, taking into account climatic p

Background -The aim of the study was to assess both mortality and morbidity following resection ofmid and low rectal cancers in a French prospective multicentric study. patients -From June to September 2002, consecutive patients undergoing resection for cancer of the mid-or lower rectum were prospectively included in amulticentric study. Both postoperative mortality and morbidity were recorded. Multivariate statistical analysis was performed in order to assess risk factors predictive of postoperative morbidity. Results -238 patients with a mean age of 66±13 years (range: 26-88) were included. Neoadjuvant radiotherapy was performed in 68%of the patients. Totalmesorectal excision was performed in 218 patients (92%), of whom 151 (63%) had a sphincter saving procedure. Six patients died (2.5%). Overall postoperative morbidity rate was 43%, including anastomotic leakage (11%) and reoperation (5%). Mean hospital-in-stay was 20 ±16 days (range: 3-191). Four independent risk factors of morbidity were found: perioperative fecal contamination (OR = 3.9 [1.1; 13.5]), mean operating time longer than 6 hours (OR = 4.5 [1.7; 12.1]), ASA score > 2 (OR = 3.2 [1.6; 7.9]), and smocking (OR = 3.3 [1.2; 8.9]). Conclusions -Resection of cancer involving the middle or lower rectum with sphincter saving procedures was possible in two-thirds of the patients and was associated with 2.5%mortality and 43%morbidity.
