The Authors reporting two cases with ileus by phytobezoar in distal jejunum and ileum, respectively, and discuss the pathophysiologic mechanism responsible for the formation of bezoars. They expose the etiological and clinical factors of this uncommon cause of small bowel obstruction and also discuss the surgical technique that consists in the removal of the phytobezoar through enterotomy.
The authors, after having examined three recent cases, explain some basic concepts about diagnostics and therapy in cystadenolymphoma of salivary glands. As a matter of fact this neoplasia, in spite of its low frequency, is very important because of its still controversial etiopathology and recent tendency in increasing its incidence in females. Today the diagnostic protocol, undertaken after clinical examination, which is necessary, consists of ultrasonography or computerized tomography. But only postoperative histological examination gives a sure diagnosis and can point out main histomorphological characteristics of tumour. Therapeutic approach can be limited to conservative treatment, which is able to respect the parotid gland, its vascularization and innervation.
The Authors state their ideas and report their experience about diagnosis and treatment of Crohn's disease. After having treated risk and etiological factors, they discuss typical anatomo-pathological lesions. Then they explain clinical diagnostic and surgical choices extensively: they prefer laparotomic approach. The Author's conclude that timely diagnosis spare heavy complications.
A case of spontaneous corneal ulcer with iris prolapse is reported in a patient suffering from rheumatoid arthritis. The concomitant presence of a pathological costal fracture, recognised to be steroid nature, suggests a correlation between the corneal manifestations and the corticosteroid therapy to be established.
The Authors discuss on anatomical and functional characteristics of ileum-colon junction, physiological narrowing in alimentary tract and often involved in benign obstruction. They report their series and analyze all inflammatory or not inflammatory diseases potentially involved, by describing them shortly and giving some information about their clinical features and imaging. The treatment of this obstruction will be done as soon as possible, before wall lesions force to make a larger resection.
The Authors enumerate main steps of acute pancreatitis natural history. Then they discuss their last five years case-report. After having stated that clinical presentation depends on anatomo-pathological conditions, they consider aetiological causes and morphopathogenetic moments involved in the onset and development of this disease. They conclude stating how only proper diagnosis and treatment can prevent its potential evolution in multiorgan failure.
UNLABELLED: Prevalence of antibody to hepatitis C virus (anti-HCV) has been widely investigated in many categories; however no data are available on hospital personnel. The aim of our study was to investigate whether hospital personnel are at risk for HCV infection. METHODS: sera collected during a prospective study on HBV infection in hospital workers done in our institution in 1985 were analyzed for the ELISA test for anti-HCV from Ortho Diagnostic System. Sera were stored at -20 degrees C and were never defrosted until tested. A population of a consecutive series of healthy volunteer blood donors was used as a control group. RESULTS: the anti-HCV prevalence was higher in hospital personnel, than in blood donors (4.5 versus 1.1, p less than 0.001, Odds Ratio 4.5, Confidence Limits 2.9-7.2). CONCLUSION: although anti-HCV is not an "ideal" test for epidemiological purposes, our study suggests that hospital personnel is at high risk for HCV infection.

41 consecutively observed patients with chronic HB virus infection in replication phase (HBeAG positive) were followed up for an average period of 60 months with a view to evaluating the frequency of spontaneous HBeAg/anti-HBe seroconversion and the influence of the event on the clinical course of the liver disease. The 41 patients, of mean age 22 years, suffered from: 26 ECP, 7 ECA, 8 CIRR. 18 patients (41%) presented HBeAg/anti-HBe seroconversion with an annual percentage of 12%, all with stable normalisation of hepatic cytolysis tests. Factors related to HBeAg/anti-HBe seroconversion were: female sex, higher mean starting values of transaminase, positive history for EVA, absence of Virus Delta superinfection. The effectiveness of antiviral treatments will only be demonstrated when seroconversion (inhibition of viral replication) is produced much more frequently than that which occurs spontaneously. Candidates for current antiviral treatment are indicated.
