Despite the efforts made, a serum marker reliable for the screening and follow-up of patients with gastric cancer has not yet been identified. The aim of this preliminary study was to test the role of pro-inflammatory cytokines interleukin 1beta, interleukin 8 and tumour necrosis factor alpha in patients with gastric cancer and in control groups. The(More)
Dieulafoy's lesions, very rare in the duodenum, are considered uncommon causes of gastrointestinal bleeding and occur from pinpoint non-ulcerated arterial lesions. We report a case of Dieulafoy's lesion of the duodenum, in which a first diagnostic approach by using endoscopy and angiography was not successful; then, due to a high operative risk, we(More)
AIM AND BACKGROUND In breast cancer, as in almost all neoplastic diseases, the prognosis is strictly related to the invasive capacity, local and distant, that characterizes the growth of all tumors. Since the mechanisms that regulate replication of the neoplastic cells, with consequent capacity to metastasize, are not completely known, identification of new(More)
BACKGROUND The treatment of acute cholecystitis in the elderly is still a subject of debate, particularly with reference to the timing of surgery and the role of laparoscopy. PATIENTS From January 1994 to June 2002 we observed 27 patients aged over 70 years with acute calcolous cholecystitis. The patients were submitted to ultrasonographic percutaneous(More)
BACKGROUND Ischemic colitis is an uncommon complication in patients with systemic lupus erythematosus but may be precipitated by colonoscopy. CASE REPORT A 43-year-old female with systemic lupus erythematosus under treatment with immunosuppressive drugs and prednisone was submitted to colonoscopy because of a change in bowel habit. Apart from the presence(More)
BACKGROUND The rare localizations of hydatidosis represent an interesting topic, especially with reference to epidemiological and diagnostic problems. Hydatid disease, common in Mediterranean countries, still remains endemic in some regions of Italy. METHODS In the period April 1983-October 2003 73 patients with hydatid disease were observed. RESULTS(More)
Vascular tumors of the stomach represent 0.9%–3.3% of all gastric neoplasms. A 41-year-old man was admitted to our department with a 3-month history of early postprandial epigastric pain, sluggish digestion, nausea, asthenia, and occasional alimentary emesis. Preoperative staging detected a submucosal neoformation in the prepyloric zone, which narrowed the(More)
Extracellular regulated kinases (ERK1/2) and c-Jun N-terminal Kinases (JNK), are generally considered to play a key role in signal transduction pathways activated by a wide range of stimuli. We studied the effects of SP600125, a novel inhibitor of both JNK and ERK1/2, in male C57/BL6 mice given with an hyper-stimulating dose of cerulein (50 microg/kg for(More)
