ABSTRACT
Gastrointestinal stromal tumors [GIST] are mesenchymal tumors occuring in the majority of cases in the stomach and small intestine, rarely in rectum, colon, esophagus or mesentery. They are derived from cells of cajal or their precursor, and are typically CD117/KIT + [95%], CD34 + [70%]. aims: is to study the epidemiological, clinical, therapeutic and evolution of astrointestinal stromal tumors. Retrospective study including all patientswith the diagnosis of GIST supported in the department of gastroenterology and surgery in universital hospital of Monastir. 25 patients were included, 12 men and 13 women with an average age of 60.5 years. Digestive symptomatology was dominated by gastrointestinal bleeding [n = 12] and abdominal pain [n = 12]. The tumor was discovered incidentally in two patients. The small intestine was the most common site of the tumor [n = 10], followed by the stomach in 9 patients, rectum in two patients, the colon [n = 1], the bulb of water [n = 1], duodenum [n = 1] and liver in a patient. The tumor size ranged from 0.8 to 24 cm. GIST was localized in 16 patients, in whom therapeutic care based mainly on surgery and optimal broad. It was metastatic in 9 patients, in whom treatment using imatinib as first-line in 4 of them with a good response in 3 patients and the possibility of R0 surgery in one patient, initial stabilization and then a secondary exhaust in a patient. The first surgery was necessary in 5 patients in complicated situation or if diagnostic doubt. The best characterization of GIST thanks to advances in cancer research has led to improved treatment of these tumors. Surgery is the standard treatment in localized forms. Imatinib is the standard treatment in metastatic GIST first line as well as adjuvant after surgery
ABSTRACT
Viral hepatitis is a public health problem in many parts of the globe. In Tunisia, the respective responsibility of five viruses [HAV, HDV, HBV, HCV and HEV] in the genesis of acute hepatitis in adults is only roughly indicated in the absence of suitable serological studies, given as important to plan appropriate preventive strategies. To approach the role of viral hepatitis in all adult with acute hepatitis, identify the current share of each virus A, B, C and E in the genesis of hepatitis and to study the epidemiological and evolution of these diseases. We conducted a prospective study over two years including patients aged from 15 to 65 years old, with clinical and / or biological acute hepatitis. Data were collected through a standard questionnaire wich covered sociodemographic charactereristics and risk factors. Blood samples were collected and were tested for IgM anti-HAV, IgM anti-HEV, HBsAg, IgM anti-HBc, anti-HCV antibodies .When serological tests were negatives, further explorations including immunological test, search for HCV RNA and a pharmacovigilance survey was conducted. Statistical analysis was performed by SPSS version 10.0 105 patients were included. Acute viral hepatitis was diagnosis in 70 patients [67%]. The proportion of patients with acute viral hepatitis A, B, C and E was 51.5%, 38.5%, 4.3% and 5.7% respectively. The risk factors of viral hepatitis A was drinking of untreated water and poor socioeconomic status. In the HBV group, the notion of sexual contact risk was found in 30% of cases. The small numbers of acute hepatitis E and C does not permit us to draw conclusions. Our study confirms the shift in age of onset of hepatitis A to the age of adolescence and young adulthood. The respective responsibilities of the different viruses studied in the genesis of acute hepatitis in adults in our area brings us closer of western populations where HAV infection predominates followed by HBV

The older age group presents a major problem in the management of acute gastrointestinal bleeding with a relatively high mortality. The study aims to describe the background characteristics, causes and outcome of acute upper gastrointestinal bleeding in the elderly in Tunisia. We retrospectively reviewed data of 401 patients aged >/= 60 years presenting with upper gastrointestinal bleeding. Information collected included history, physical examination findings, laboratory data, endoscopic findings and length of hospital stay. Patients were divided into two groups: group A [65-79 years] and group B [>79 years]. Group A included 315 patients and group B 86 patients. There was a male preponderance in both groups. Co-morbidity [p < 0.01] and use of non-steroidal anti-inflammatory drugs [NSAIDs] or anti-platelet drugs [p < 0.01] were more common in group B. Oesophagitis was the cause of bleeding in 38.37% in group B, as compared with 19% in group A. The main cause of bleeding in group A was peptic ulcer. Rebleeding [6/86] and emergency surgery [1/86] were rare in group B and not different from those in group A. However, the bleeding-related mortality in the very elderly group was higher [13.9% vs. 4.76%; p = 0.02]. In multivariate analysis, only shock on admission was independently related to mortality [p = 0.02]. Oesophagitis is the major cause of upper gastrointestinal haemorrhage in the very elderly patients. While rebleeding and emergency surgery rates are relatively low, the bleeding-related mortality was higher in the very elderly group
