Pathogenesis of carcinoma of the papilla of Vater

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.     

Demonstration of the mechanism of action of biguanides

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.

胰岛素瘤的解剖分布特点分析

目的胰岛素瘤是最常见的胰腺神经内分泌肿瘤，因其临床表现多样，导致诊断困难。影像学诊断尤其是超声内镜(EUS)在胰岛素瘤的诊断中起着重要作用，拥有较高的敏感性和特异性。本研究拟通过明确胰岛素瘤的解剖分布特点，以期有助于提高影像学的诊断准确率和降低漏诊率，尤其是在教育和培训实践中对于EUS的学习者更具有指导价值。 方法回顾性分析解放军总医院第一医学中心病案资料数据库1993年1月至2019年11月经外科手术、病理确诊为胰岛素瘤的患者的临床资料，检索方法采取搜索术后病理诊断为"胰岛素瘤"的病例，通过查阅病例的方法，提取出胰岛素瘤的大小和解剖分布等数据，进一步分析其特点。 结果共检索到确诊为胰岛素瘤的患者116例，其中，男45例、女71例，年龄13～76岁，平均年龄(44.4±14.85)岁。胰岛素瘤单发110例(94.8%)、多发6例(5.2%)。位置分布：头颈部46例(39.7%)，单发45例、多发1例；体尾部68例(58.6%)，单发65例、多发3例；全胰腺多发2例(1.7%)。病变大小特点：最大径0.4～3.4 cm，平均大小(1.53±0.58)cm。≤1 cm 29例、>1 cm而≤1.5 cm41例、>1.5 cm而≤2.0 cm28例，≤3 cm 15例，>3 cm 3例。年龄与肿瘤的大小相关，≤44岁患者肿瘤平均大小为(1.36±0.51)cm、>44岁患者肿瘤平均大小为(1.70±0.60)cm，P<0.05。头颈部的肿瘤大于体尾部的肿瘤，头颈部肿瘤平均大小(1.66±0.63)cm，体尾部(1.42±0.52)cm，P<0.05。 结论胰岛素瘤在胰腺体尾部较头颈部更好发；绝大多数单发，但可以全胰腺多发；多数小于1.5 cm，肿瘤的大小与患者年龄和肿瘤的解剖分布相关。     

氯硝柳胺悬浮剂的毒性评价

Lack of correlation of degree of villous atrophy with severity of clinical presentation of coeliac disease

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.

Results of treatment of fistula-in-ano

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.

Intake of energy drinks in association with alcoholic beverages in a cohort of students of the School of Medicine of the University of Messina

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.
