Most adenomas and carcinomas of the small intestine and extrahepatic bile ducts arise in the region of the papilla of Vater. In familial adenomatous polyposis (FAP) it is the main location for carcinomas after proctocolectomy. In many cases symptoms due to stenosis lead to diagnosis at an early tumor stage. In about 80%, curative intended resection is possible. Operability is the most relevant prognostic factor. Most ampullary carcinomas resp. carcinomas of the papilla of Vater develop from adenomatous or flat dysplastic precursor lesions. They can be sited in the ampulloduodenal part of the papilla of Vater, which is lined by intestinal mucosa. They also can develop in deeper parts of the ampulla, which are lined by pancreaticobiliary duct mucosa. Intestinal-type adenocarcinoma and pancreaticobiliary-type adenocarcinoma represent the main histological types of ampullary carcinoma. Furthermore, there exist unusual types and undifferentiated carcinomas. Many carcinomas of intestinal type express the immunohistochemical marker profile of intestinal mucosa (keratin 7?, keratin 20+, MUC2+). Carcinomas of pancreaticobiliary type usually show the immunohistochemical profile of pancreaticobiliary duct mucosa (keratin 7+, keratin 20?, MUC2?). Even poorly differentiated carcinomas, as well as unusual histological types, may conserve the marker profile of the mucosa they developed from. These findings underline the concept of histogenetically different carcinomas of the papilla of Vater which develop either from intestinal- or from pancreaticobiliary-type mucosa of the papilla of Vater. Molecular alterations in ampullary carcinomas are similar to those of colorectal as well as pancreatic carcinomas, although they appear at different frequencies. In future studies, molecular alterations in ampullary carcinomas should be correlated closely with the different histologic tumor types. Consequently, the histologic classification should reflect the histogenesis of ampullary tumors from the two different types of papillary mucosa.  相似文献

Summary Palmitic acid oxidation in rat diaphragm homogenate is depressed by biguanide concentrations that are still incapable of inhibiting oxidative phosphorylation. Glucose oxidation is not directly effected by the same biguanide concentrations: however, the inhibitory effect of palmitic acid on glucose oxidation is partly removed by biguanides. Inhibition of fatty acid oxidation, which accounts for most of the metabolic effects caused by these drugs, can be regarded as the fundamental mechanism of action of biguanides. There is some evidence suggesting that these drugs might interact with carnitine, thus preventing long-chain fatty acids from being transported across the mitochondrial membrane to the site of oxidation.

BACKGROUND AND AIM: Both the clinical presentation and the degree of mucosal damage in coeliac disease vary greatly. In view of conflicting information as to whether the mode of presentation correlates with the degree of villous atrophy, we reviewed a large cohort of patients with coeliac disease. PATIENTS AND METHODS: We correlated mode of presentation (classical, diarrhoea predominant or atypical/silent) with histology of duodenal biopsies and examined their trends over time. RESULTS: The cohort consisted of 499 adults, mean age 44.1 years, 68% females. The majority had silent coeliac disease (56%) and total villous atrophy (65%). There was no correlation of mode of presentation with the degree of villous atrophy (p=0.25). Sixty-eight percent of females and 58% of males had a severe villous atrophy (p=0.052). There was a significant trend over time for a greater proportion of patients presenting as atypical/silent coeliac disease and having partial villous atrophy, though the majority still had total villous atrophy. CONCLUSIONS: Among our patients the degree of villous atrophy in duodenal biopsies did not correlate with the mode of presentation, indicating that factors other than the degree of villous atrophy must account for diarrhoea in coeliac disease.  相似文献

研究幽门螺杆菌(Hp)感染与胃炎的关系。方法对204例慢性胃炎患者胃粘膜进行观察分析,并测定其中137例Hp阳性患者血清CagA-Hp抗体IgG水平,与组织学对照。结果慢性萎缩性胃炎伴肠上皮化生患者血清CagA抗体IgG明显高于对照组(P<0.01);其他类型胃炎患者血清CagA抗体IgG水平无明显增高(P>0.05)。结论CagA-Hp可能是导致慢性萎缩性胃炎伴肠上皮化生的因素之一,对这类患者应密切随访观察。  相似文献

目的探讨慢性阻塞性肺病急性加重期(AECOPD)患者预后的相关危险因素。方法回顾性调查、收集58例AECOPD患者可能影响其预后的相关因素,并对其分别进行单因素分析。并进行Logistic多元逐步回归进行多因素分析,筛选影响AECOPD患者预后的独立危险因素。结果单因素分析后将结果 P0.1的因素纳入多因素Logistic回归,分析发现是否合并呼吸衰竭、气促程度、白细胞计数、APACHEⅡ、应用抗氧化剂、慢阻肺治疗依从性为影响AECOPD患者预后不佳的独立因素(P0.05)。结论根据AECOPD患者预后的独立危险因素,及早判断,选择合适的后续治疗方案,对提高其生存率及生存质量具有重要意义。  相似文献

Results of treatment of fistula-in-ano   总被引:4,自引:1,他引:3  
To evaluate the application of Parks' classification in the management of patients with fistula-in-ano, a study was undertaken to assess the outcome of surgery, especially with respect to the recurrence rate and alteration of continence. A retrospective analysis of 160 consecutive patients who were classified at the time of operation was conducted. The distribution of fistulas was as follows: intersphincteric, 41.9 percent, transsphincteric, 52.1 percent, suprasphincteric, 1.3 percent, extrasphincteric, 0. A horseshoe extension occurred in 8.8 percent of the fistulas and 3.8 percent did not exactly conform to the classification as they were either complex or combinations of more than one type of fistula. The sole immediate postoperative complication was bleeding, which occurred one week postoperatively and ceased spontaneously (0.7 percent). Alteration in continence occurred in 6 percent of patients with 2.6 percent experiencing temporary incontinence to flatus, 1.3 percent to liquid stool, and 0.7 percent to solid stool. Permanent loss of control for flatus occurred in one patient (0.7 percent) and for liquid stool in one patient (0.7 percent). No patients suffered loss of control for solid stool. Recurrence developed in 6.3 percent of patients, all between five and 25 months postoperatively. Classifcation was found to be a useful guide in the operative management of patients with fistula-in-ano.

BACKGROUND: Energy drinks (ED) are a widely used group of beverages known for their stimulant effects on central nervous system (CNS). The main components of ED are caffeine, taurine, carbohydrates, glucuronolactone, inositol, niacin, pantenol, and beta-complex vitamins. The studies evaluating the effects of ED describe improvements in attention and/or reaction times and indices of alertness. It has been also shown that combination of caffeine and glucose, fundamental constituents of ED, can ameliorate deficits in cognitive performance and subjective fatigue during extended periods of cognitive demand. Moreover, the associated ingestion of alcohol and ED has recently been observed to be becoming more and more widespread. METHODS: With the aim to know the habits and uses of students, we administered a questionnaire containing questions regarding ED drinking alone or in association with alcoholic beverages. Five hundred students of the School of Medicine of the University of Messina were interviewed, and 450 filled the questionnaire. RESULTS: A total of 56.9% of students declared using ED. A great part of users (48.4%) associate frequently ED and alcohol. In particular, 35.8% of ED + alcohol users have used ED + alcohol more than 3 times in the last month. Distinguishing the users into 2 groups (users of ED + alcohol and users of both ED and ED + alcohol), we observed in the second group a major use of cocktail containing a mix of ED and alcoholic beverages. This difference between the 2 groups is less represented about the ingestion of ED + alcohol in the night. CONCLUSIONS: Our data indicate that association of ED + alcohol is very popular among students. This behavior can be dangerous. In fact, the combination of ED + alcoholic drinks can reduce adversive symptoms of alcohol intoxication including the depressant effects. As consequence, users of ED + alcoholic beverages might not feel the signs of alcohol intoxication, thus increasing the probability of accidents and/or favoring the possibility of development of alcohol dependence.  相似文献
