RESUMO

Introduction: Spontaneous intrahepatic portosystemic shunts are rare vascular anomalies that consist of a communiation between the portal system and the systemic venous circulation. We report a case of a porto-caval shunt associated with chronic pericarditis


Case report: A 47-year-old patient with post pericarditis cirrhosis and without encephalopathy and hypoglycaemia. The shunt was tubular in its initial segment and aneurismal just before joining the vena cava


Discussion: Spontaneous intrahepatic portosystemic shunt is a rare anomaly. Diagnosis can ve made by Doppler ultrasound and helical CT

RESUMO

Introduction: Crohn's disease of the stomach is rare. There is nearly always concomitant disease in the small bowel or colon. Gastric involvement occurs rarely as an isolated entity. Upper endoscopy is sensitive for detecting subtle disease but more extended lesions can mimic neoplasms such us linitis


Exegese: A 74-year old female was admitted to hospital with abdominal pain, vomiting and weight loss. Upper endoscopy and radiology aspects was suspicious of gastric linitis. Multiple endoscopic biopsies of the stomach showed one granuloma, chronic inflammation and Helicobacter Pylori. Because of the importance of obstructive syndrome, the patient underwent surgery. The resected stomach concluded to a Crohn's disease


Conclusion: Through this observation, we review clinical characteristics, diagnostic difficulties and treatment options of Crohn's disease of the stomach

RESUMO

Gastric cancer is a serious disease with a high mortality rate. Early diagnosis of the disease improves its prognosis. We report two cases of early gastric cancer and we specify the clinical, endoscopic, histologic and therapeutic aspects of the disease. This study is about two female patients, respectively, 36 and 70 years old. The diagnosis of early gastric cancer was based on pathologic examination of the resected stomach.The two patients are in remission 2 years and 6 months later, respectively. The diagnosis of early gastric cancer is often made on nonspecific symptoms. Oeso-gastro-duodenoscopy shows gastric mucosal anomalies. Pathologic examination of gastric biopsies confirm the diagnosis of adenocarcinoma. Endoscopic ultrasound is essential; it specifies the submucosal infiltration and evaluates the lymph node invasion. Surgery is the primary treatment but in some cases endoscopic mucosal resection provides good long-term results. Early diagnosis of adenocarcinoma improves the prognosis of the disease, which remains poor nowadays

RESUMO

the aim of the study was to review the principal effects of probiotics on pouchitis and identify their mechanisms of action. the study was based on a review of all relevant studies published in the literature on the effects of probiotics in pouchitis and their possible mechanisms of action. pouchitis is the major long-term complication after ileal pouch anal anstomosis for ulcerative colitis. The cause is still unknown but is likely to be multifactorial. An imbalance in the usual fecal flora was recently suggested. Most patients with symptoms of pouchitis respond promptly to antibiotics. However, 5-10% of them develop rapidly relapsing symptoms that require protacted therapy. Porbiotics are living microorganisms that ingested in adequate amounts exert beneficial effects. Promising results have been obtained with probiotics mainly in maintenance of remission of chronic pouchitis and also as induction of remission. These results suggest that restoring the microbial imbalance may offer an effective therapeutic alternative to patients with pouchitis

RESUMO

the aim of the study was to review the pathogenic mechanisms of auto-immune hepatitis. the study was based on a review of all relevant articles from literature on the mechanisms of auto-immunity in auto-immune hepatitis. the precise mechanisms through which liver damage occurs are not fully understood. Autoimmune hepatitis seems to be a consequence of auto-antigen exposure, genetic predisposition and defective immuregulatory mechanisms. Auto-antigen is presented by class II molecules of the major histocompatibility complex. Cytokines and non specific auto-immune promoters modulate immune reactivity. Cellmediated and antibody-dependent forms of cytotoxicity are probably interactive pathogenic mechanisms. disturbance in the tight balance between auto aggression and self-tolerance, affected by several internal and external factors are likely in auto-immune hepatitis

RESUMO

The liver diseases of pregnancy are specific liver disorders during the pregnancy. The principal hepatic anomaly during hyperemesis gravidarum is a reversisble augmentation of liver enzymes under reanimation. lntrahepatic cholestasis of pregnancy occur during the last 2 trimesters of pregnancy, manifested usually by pruritis preceeding a jaundice. The liver enzymes and the serum biliary acids are augmented. The acute fatty liver of pregnancy occur during the last trimester of pregnancy leading to early interruption of pregnancy which would help to diminish the elevated level of maternal and fetal mortality. The HELLP syndrome usually observed during the toxemia of pregnancy, associate an hemolysis elevation of liver enzymes and low platelets
