Possible genetic defects in regulation of glycosaminoglycans in patients with diabetic nephropathy 总被引:1,自引:0,他引:1
T Deckert I M Horowitz A Kofoed-Enevoldsen L Kjellén M Deckert C Lykkelund F Burcharth 《Diabetes》1991,40(6):764-770
The hypothesis of genetic defects in glycosaminoglycan (GAG) regulation among patients with insulin-dependent diabetes mellitus (IDDM) and nephropathy was assessed by studies in tissue cultures of fibroblasts obtained from 7 patients with normal urinary albumin excretion, 11 patients with diabetic nephropathy, and 6 nondiabetic control subjects. The incorporation of [2H] glucosamine and [35S] sulfate into hyaluronic acid (HA), chondroitin sulfate and dermatan sulfate (CS + DS), and heparan sulfate (HS) was measured in cells, matrix, and medium and related to micrograms of tissue protein. Large interindividual variations were seen in all three groups, and the incorporation of [3H] glucosamine into HA, CS + DS, and HS and [35S] sulfate into CS + DS and HS were not significantly different between the three groups. However, the fractional incorporation of [3H]glucosamine into HS was significantly reduced in diabetic patients with nephropathy compared with control subjects. This was the case not only when related to the total amount of GAGs (P = 0.014) but also when related to HA (P = 0.014). No significant difference was seen between control subjects and normoalbuminuric diabetic patients. The degree of N-sulfation of HS was not significantly different between the experimental groups. The results suggest that patients with diabetic nephropathy may suffer from deficiencies of coordinate regulation in the biosynthesis of GAG in fibroblasts, which may lead to a reduced density of HS in the extracellular matrix. If these changes reflect alterations in the biosynthesis of GAG from endothelial, myomedial, and mesangial cells, this observation may be relevant for the pathogenesis of severe diabetic complications. 相似文献

The perfusion of two pancreatic transplants were examined three times a week for the first five postoperative weeks by intravenous angiography using 99Tcm-pertechnetate. Worsening of the perfusion always preceded or was associated with deterioration of the pancreatic function. Accordingly, radionuclide angiography may have an important place in the systematic monitoring of pancreatic transplants in the critical postoperative period. 相似文献

Purpose
The aim of this was to assess potential risk factors for anastomotic dehiscence in colon cancer surgery in a national cohort.Methods
All patients, who had undergone a resection of a large bowel segment with an anastomosis between 2008 and 2011, were identified in the Swedish Colon Cancer Registry. Patient factors, socioeconomic factors, surgical factors, and medication and hospital data were combined to evaluate risk factors for anastomotic dehiscence.Results
The prevalence of anastomotic dehiscence was 4.3 % (497/11 565). Male sex, ASA classification III–IV, prescribed medications, bleeding more than 300 mL, and uncommon colorectal resections were associated with a higher risk of anastomotic dehiscence. Hospital stay was increased with 14.5 days, and 30-day mortality as well as long-term mortality was higher in the anastomotic dehiscence group.Conclusions
There are several factors that are possible to know preoperatively or during surgery that can indicate whether an anastomosis is an appropriate option. Anastomotic dehiscence increases hospital stay and long-term mortality.4.

One hundred and forty-eight patients admitted with their first episode of acute pancreatitis were examined by ultrasonography. During the acute attack 1 or more pseudocysts were found in 19 patients (13%), pancreatic abscess in 2, whereas 127 had a normal or swollen pancreas. Two small cysts resolved spontaneously, eight were cured after ultrasonically guided needle aspiration or catheter drainage, and cystogastrostomy was necessary in four cases. One patient refused treatment. Abscesses requiring surgical drainage developed in four of the patients with pseudocysts. The study showed that pseudocysts may appear as early as within 1 week of the first episode of acute pancreatitis. Some pseudocysts may resolve spontaneously, and ultrasonically guided aspiration or drainage may cure approximately half of the pseudocysts. 相似文献

Pancreaticoduodenectomy for periampullary cancer in patients more than 70 years of age 总被引:6,自引:0,他引:6

BACKGROUND/AIMS: To assess the indications for and results of pancreaticoduodenectomy in patients more than 70 years old with periampullary cancer. METHODOLOGY: Thirty-four consecutive patients older than 70 years with periampullary cancer. The surgical procedure was pancreaticoduodectomy (Whipple's operation) with an extensive dissection of lymph nodes and the connective tissue in the peripancreatic region. Main outcome measures were postoperative morbidity and mortality, median and 5-year survival rates. RESULTS: Postoperative medical complications occurred in 24% and surgical complications in 53% of the patients. Four patients (12%) died in the postoperative period (within 30 days), and 3 patients (9%) died later in the postoperative course. The cumulative and age corrected 5-year survival rate for the remaining patients was 26%. Fifteen patients died of recurrence, and 7 patients of other causes. Five patients are still alive more than 5 years after surgery. In patients with noncurative operation the median survival time was 1 1/2 years, which is longer than would be expected from other palliative procedures. Apart from a moderately increased postoperative mortality the results were similar to those reported for younger patients. CONCLUSIONS: Pancreaticoduodenectomy should be considered in patients older than 70 years with resectable periampullary cancer. A 5-year survival rate of 20-35% can be obtained. Palliative resection may be indicated in patients in good general condition, as resection gives the best palliation and longer survival than other palliative methods. 相似文献

Percutaneous transhepatic portography with selective catheterization of the portal vein and its tributaries was performed on 120 patients, of whom 71% had cirrhosis of the liver. The technique was improved by ultrasonically guided puncture, and the procedure was successful in 96% of the examinations. Collateral veins were visualized in 81% and esophageal or gastric varices in 69% of the patients with portal hypertension. The procedure was performed with little risk and discomfort, and portograms of high quality were obtained. Other applications of percutaneous transhepatic catheterization of the portal vein system are discussed. 相似文献

A case of traumatic abdominal hernia is reported in a patient with a history of chronic cough. After a bout of coughing 3 months prior to her presentation, the patient developed a large herniation on the left lateral side of the abdomen. The patient presented with intestinal obstruction due to the herniation. A CT scanning confirmed the hernia and showed a peritoneal defect with herniation of most of the intestine on the left lateral side of the abdomen. An emergency midline laparotomy was performed, and the defect was corrected. 相似文献

Nonsurgical internal biliary drainage by endoprosthesis 总被引:1,自引:0,他引:1

Insertion of an endoprostheses for internal biliary drainage was attempted upon 150 patients with obstructive jaundice. It was successful in 123 patients, and 99 patients had permanent drainage with the endoprosthesis. The plasma bilirubin level became normal in 64 of the patients. The effect upon jaundice was equal to that in 43 patients who underwent operation with palliative surgical bypass. The median survival time was not different from that for the patients with surgical anastomoses. Twenty-eight patients died in the first month after insertion, mostly of advanced malignant disease. Fifteen of the patients in the group with surgical anastomoses died within the first month. The insertion of an endoprosthesis for bile duct obstruction is relatively easy and seems to have little risk. Most complications are caused by the transhepatic cholangiography procedure. The method may be used for temporary drainage before operation, in transient benign obstructions or as permanent drainage in unresectable lesions. In patients with dislodgement or insufficient function, additional endoprosthesis may be inserted. Thus, sufficient palliation of jaundice is achieved with a low frequency of cholangitis. Internal biliary drainage by insertion of an endoprosthesis is a valuable alternative to surgical bypass in patients with unresectable lesions. 相似文献

Ultrasonically guided percutaneous implantation of iodine-125 seeds in pancreatic carcinoma. 总被引:6,自引:0,他引:6

Cancer of the pancreas is most often not diagnosed before it has reached unresectable stages. The development of effective palliative treatment for these patients and for those with recurrence after resection is clearly needed. The present study reports the results of ultrasonically guided percutaneous implantation of 125I seeds in 19 patients with cancer of the pancreas. Twelve patients had further adjuvant external radiation. Despite satisfactory seed placement and delivery of the planned radiation dose in most cases, clinical improvement was lacking or only slight and short-lived. No difference in survival or palliation was observed between patients treated with seeds alone compared with patients treated with seeds and external radiation. Survival after seed implantation was short (median 140 days, range 7-401 days). Ultrasonically guided percutaneous implantation of 125I seeds cannot be recommended in the treatment of unresectable carcinoma of the pancreas. 相似文献
