Gas lucency within intervertebral disc spaces, the vertebral vacuum phenomenon (VVP) was visible radiographically in 12/42 (28%) women with adenocarcinoma of the breast metastatic to bone. In 7/12 (17%) the VVP occurred adjacent to vertebra involved with metastatic tumor and free of significant degenerative changes. Vertebral collapse occurred in all seven women, but was minimal in some when the VVP was prominent. Metastatic malignancy should be considered along with degenerative disease when the VVP is observed. 相似文献

AIM: The aim of this retrospective study was to report the results of the laparoscopic management of common bile duct stones in an unicentric series of 30 patients. METHODS: From January 2001 to April 2004. 30 patients: 23 women, 7 men (mean age: 54 years). underwent a common bile duct exploration for lithiasis through a laparoscopic approach. The patients were hospitalized for angiocholitis (n = 12), cholecystitis (n= 4), jaundice (n = 4), pancreatitis (n = 3), abnormality of hepatic tests (n = 7). All the patients underwent an intra operative cholangiography. Removal of the stones was tried in 30 cases through a choledochotomy. never through the cystic duct, using Dormia and Fogarty catheters. External biliary drainage with T tube (kehr) and postoperative cholangiography was done systematically. RESULTS: In 21 patients (70 %), removal of the stones was laparoscopically successful. The average diameter of the common bile duct was 10.5 mm (range 6-20 mm). The median number of stones was 5 (E: 1-12). The median operation time was 180mn (range 150-300mn). In 9 patients, a conversion into laparotomy was necessary for several reasons. In 2 patients with residual common bile duct, the stones were treated successfully by endoscopic sphincterotomy. There was no mortality and the morbidity rate was 10 %. The mean postoperative hospital stay was 14.7 days (range 7-18days) and 13.3 days in case of successful laparoscopic management. CONCLUSION: In 70 % of the patients, the treatment of the common bile-duct lithiasis could be achieved laparoscopically, but conventional approach and endoscopic sphincterotomy are still useful in case of failure of the laparoscopic management. 相似文献

The effect of insulin infusion upon protein metabolism in neonates on extracorporeal life support 下载免费PDF全文
OBJECTIVE: Critically ill neonates on extracorporeal life support (ECLS) demonstrate elevated rates of protein breakdown that, in turn, are associated with increased morbidity and mortality. This study sought to determine if the administration of the anabolic hormone insulin improved net protein balance in neonates on ECLS. METHODS: Twelve parenterally fed neonates, on ECLS, were enrolled in a randomized, prospective, crossover trial. Subjects were administered a hyperinsulinemic euglycemic clamp and a control saline infusion. Protein metabolism was quantified using ring-D5-phenylyalanine and ring-D2-tyrosine stable isotopic infusions. Statistical comparisons were made by paired sample t tests (significance at P < 0.05). RESULTS: Serum insulin concentration increased 20-fold during insulin infusion compared with saline infusion control (P < 0.0001). Protein breakdown was significantly decreased during insulin infusion compared with controls (7.98 +/- 1.82 vs. 6.89 +/- 1.03 g/kg per day; P < 0.05). Serum amino acid concentrations were significantly decreased by insulin infusion (28,450 +/- 9270 vs. 20,830 +/- 8110 micromol/L; P < 0.02). Insulin administration tended to decrease protein synthesis (9.58 +/- 2.10 g/kg per day vs. 8.60 +/- 1.20; P = 0.05). For the whole cohort, insulin only slightly improved net protein balance (protein synthesis minus protein breakdown) (1.60 +/- 0.80 vs. 1.71 +/- 0.89 g/kg per day; P = 0.08). In neonates receiving > or =2 g/kg per day of dietary amino acids insulin significantly improved net protein balance (2.17 +/- 0.34 vs. 2.40 +/- 0.26 g/kg per day; P < 0.01). CONCLUSIONS: Insulin effectively decreases protein breakdown in critically ill neonates on ECLS. However, this is associated with a significant reduction in plasma amino acids and a trend toward decreased protein synthesis. Insulin administration significantly improves net protein balance only in those ECLS neonates in whom adequate dietary protein is provided. 相似文献

Serial transverse enteroplasty enhances intestinal function in a model of short bowel syndrome 总被引:3,自引:0,他引:3 下载免费PDF全文
OBJECTIVE/SUMMARY BACKGROUND DATA: Serial transverse enteroplasty (STEP) is a new intestinal lengthening procedure that has been shown to clinically increase bowel length. This study examined the impact of the STEP procedure upon intestinal function in a model of short bowel syndrome. METHODS: Young pigs (n=10) had a reversed segment of bowel interposed to induce bowel dilatation. Five pigs underwent a 90% bowel resection with a STEP procedure on the remaining dilated bowel while 5 served as controls and had a 90% bowel resection without a STEP procedure. Determinations of nutritional status, absorptive capacity, and bacterial overgrowth were conducted 6 weeks after resection. Statistical comparisons were made by 2-sample t test (significance at P<0.05). RESULTS: The STEP procedure lengthened the bowel from 105.2+/-7.7 cm to 152.2+/-8.3 cm (P<0.01). The STEP animals showed improved weight retention compared with controls (mean, -0.5%+/-1.8% body weight versus -17.6%+/-1.5%, P<0.001). Intestinal carbohydrate absorption, as measured by d-Xylose absorption and fat absorptive capacity as measured by serum vitamin D and triglyceride levels, were increased in the STEP group versus controls. Serum citrulline, a marker of intestinal mucosal mass, was significantly elevated in the STEP pigs compared with controls. None of the STEP animals but 4 of 5 control animals were noted to have gram-negative bacterial overgrowth in the proximal bowel. CONCLUSIONS: STEP improves weight retention, nutritional status, intestinal absorptive capacity, and serum citrulline levels in a porcine short bowel model. A salutary effect upon bacterial overgrowth was also noted. These data support the use of this operation in short bowel syndrome. 相似文献

Thioeserine, the Thioanalogue of Eserin From deoxyeseroline ( 4a ) 5-rhodanodeoxyeseroline ( 4b ) is generated by treatment with thiocyanogen. 4b gives thioeseroline ( 4c ) by reduction with LiAlH4 and 4d is produced by reaction of 4c with methyl isocyanate. 相似文献

Kangari, an earthenware brazier containing burning charcoal, is used for personal warming during the winter months by most of the people in Kashmir valley. Kangari is usually held close to the lower abdomen or in between the legs while squatting on the ground. The use of kangari is associated with development of skin cancer at the sites of prolonged exposure. In the present study 43 patients with Kangari cancer were analyzed prospectively with the objective of understanding their clinico-pathological profile and the response to various treatment modalities. Variables such as age, gender, grade, site of lesion etc., were evaluated for their prognostic significance. 相似文献
