The bulb ulcer stenosis, becoming exceptional in developed countries, remains frequent in our country despite the use of the antisecretory. The purpose of our study was to study epidemiological, diagnostic, and evolutionary complication particularities, and to find potential predictive factors of resistance of ulcer stenosis of the bulb to the pump inhibitors Proton through a recent series. This is a retrospective and descriptive study involving 105 patients, treated for ulcer stenosis of the bulb between January 2007 and December 2012. All our patients had received inhibitors of Proton pump, parenterally for 7 days. They were divided into 2 groups according to their response to treatment: the first group (G1) was sensitive and the second (G2) was resistant. All patients of the G2 were operated. We had compared the two groups. There was no statistically significant difference concerning age, sex, blood group and smoking between the two groups. In univariate study, the age of the epigastralgies was greater than or equal to 9 years;the clapotage fasting, dilation and gastric atony, objectified by the oesogastroduodenal transit were significantly associated with the failure of medical treatment. Only gastric atony and seniority of the disease over 9 years were independent risk factors of resistance to the Proton pump inhibitors in multivariate study.

Introduction: The aim of this study was to clarify the role of laparoscopy in the etiological diagnosis of exudative ascites of unknown origin in women. Materials and Methods: This?was?a prospective study from 2007 to 2012, including 83 women with exudative ascites of unknown origin and had a laparoscopy diagnostic purpose. Results: Carcinomatosis and peritoneal tuberculosis were the two most common causes found in 31% (26 cases) and 66% (55 cases) of cases respectively. The average age of the patients was 56 years. Weight loss and abdominal pain were the most frequent, observed symptoms in 71 cases (85.5%) and 53 cases (63.8%) respectively. The CT scan abnormalities noted?were a peritoneal thickening in 32 cases (38.5%), peritoneal nodules in 15 cases (18%), and agglutination of the digestive handles in 12 cases (14.4%). Laparoscopic Visual diagnosis was in favor of a peritoneal carcinomatosis in 32 cases (38.5%), peritoneal tuberculosis in 45 cases (54.2%), and non specific infection in 6 cases (7.3%). The histological diagnosis was a peritoneal carcinomatosis in 26 cases (31%), and peritoneal tuberculosis in 55 cases (66%). The positive predictive value of laparoscopic vision Diagnostics in Peritoneal tuberculosis was 100% and the negative predictive value was 73.7%. In peritoneal carcinomatosis, the positive predictive value was 81.3% and the negative predictive value was 100%. Conclusion: The etiologic diagnosis of exudative ascites in women is difficult despite the availability of several tests. Currently, laparoscopy with peritoneal biopsy remains the gold standard for etiologic diagnosis.

In recent years, the hepatotoxic potential of thiopurines, in particular 6-thioguanine (6-TG), has been discussed in literature. However, cirrhosis was exceptionally reported. We report the case of a 56-year-old woman with ileocaecal Crohn’s disease treated with azathioprine. After taking azathioprine (2 mg/kg daily) for four years, she underwent surgical treatment for acute intestinal obstruction. In peroperative, we noticed a cirrhotic liver. A surgical biopsy was performed and the diagnosis of cirrhosis was confirmed. Autoimmune and viral liver diseases were ruled out by laboratory parameters. Therefore, Azathioprine is believed to be the causative factor for inducing liver cirrhosis. Thus, treating inflammatory bowel disease effectively while trying to limit iatrogenic disease is a continuous struggle.

With an aim of rationing use of energy, energy safety, and to reduce carbon emission, our interest was geared towards the refrigerators and all the refrigerating machines. Indeed the heat yielded by the exchanger condenser can be developed for the water heating, floors heating etc. After an encouraging theoretical study, two prototypes were produced in order to validate the theoretical results. A first refrigerator was coupled with a water-heater and another with a heating floor. The water temperature reached, in one day, is of 60℃;which makes it possible to predict better results with a continuously used refrigerator. In the same way for the heating floor coupled with the second refrigerator, the temperature reached high values because the surface is reduced;however for the heating floors the standard fixes the temperature between 28℃ and 30℃.

Our contribution in the production of hydrogen, vector of energy, consists in testing the water electrolysis by photovoltaic solar energy. The realization of some electrolysers whose electrodes are various materials, showed a clear difference from the point of view produced hydrogen flow, conversion efficiency, energy specific consumption and the electrodes lifespan. This made it possible to classify materials, by performances descending order, as follows: copper, lead, bronzes, aluminum, stainless, graphite and steel. However lead has a too low flow and aluminum corrodes quickly. Steel admits poor yield and lifespan. Then, we retain primarily copper like anode metal. To increase the hydrogen produced flow by electrolysis, the electrolysers parallel assembly choice is essential. According to the hour of the day, the evolution of the parameters such as consumed current, efficiency, and specific energy differs from a material with another, which can be explained by the variation of solar energy during the day.

In order to popularize the use of the solar-water heaters, especially in the residential and tertiary sectors with the third world, it appears to be necessary to reduce their cost while improving their performances. It is the object of this integrated storage collector thus created and tested in the south of Tunisia. It is simply made up of a tank playing the double part of solar absorber and storage tank of warm water, of a glazing to profit from the greenhouse effect and of an insulating case. Its measured energy performances, by the method of input-output proves its effectiveness to produce hot water, in spite of its simplicity of manufacture, usage and maintenance. Indeed a temperature of water exceeding 70?C is reached towards the afternoon True Solar Time, and for an efficiency of 7%. Thus, this type of collector with integrated storage is entirely satisfactory and could be available to larger mass.
