The association between venous thromboembolism and cancer has been widely documented and the main factor responsible for cancer-induced venous thromboembolism is considered mostly linked to a hypercoagulation state induced by the cancer itself. There is no consensus on investigative strategies for occult cancer in a patient with a thrombophilic condition. We report a patient who manifested an isolated episode of pulmonary embolism without specific evident sources of venous thromboembolism. The routine clinical and laboratory work-up to detect an occult cancer did not reveal any malignancy. A history of duodenal ulcer in association with a recent slight alteration in bowel habits led us to perform an esophagogastroduodenoscopy which was negative for malignancy, and a barium enema followed by colonoscopy, which revealed the presence of a tumor limited to the large intestine. An unexplained clinically evident hypercoagulation state, even in the presence of mild clinical symptoms, needs more thorough diagnostic strategies when simple methods of screening for occult cancer are negative.

Background/aims: Although a primary carcinogenic role of alcohol is not proven, alcohol abuse is associated with an increased risk of cancer of the upper airways, esophagus and liver., Methodology: Chromosome aberrations and the presence of micronuclei that reflect two types of genetic damage were analyzed in peripheral blood lymphocytes from 11 alcoholic patients who were heavy smokers and in a fair state of general nutrition and 9 subjects who had abstained from alcohol for at least a year. Ten heavy smokers were studied as healthy controls., Results: Chromosome aberrations and micronuclei in alcoholics showed significantly elevated frequencies compared to the control groups, while in alcohol abstainers the values of all two parameters were similar to the values of the control subjects., Conclusions: These results show that long-term alcohol intake could induce genetic alterations in synergy with tobacco smoke. Interestingly, this damaging action is reversed by abstinence. Our results call for a further effort to find an eventual diagnostic role for these early genetic damage markers.

Background/aims: The evaluation of the efficacy of two different forms of scientific information concerning alcohol-related problems (ARP), among Italian trainee nurses., Methodology: A specific questionnaire, investigating the awareness of ARP, was distributed to 193 trainee nurses, 158 enrolled in the Italian Red Cross School for Professional Nurses at S. Orsola-Malpighi Hospital in Bologna and 35 enrolled in the Professional Nursing School at the Social Security Institute in the Republic of San Marino, who had attended a scientific meeting on ARP in the last year. Eighty-one nurses (62 belonging to the Red Cross School of Bologna and 19 to the Professional Nursing School of San Marino), had previously been given an information package on ARP (Group A). One hundred twelve subjects (96 belonging to the Red Cross School of Bologna and 16 to the Professional Nursing School of San Marino) did not read the specialized material (Group B)., Results: The results showed a statistically significant difference in the percentage of correct answers between Group A (25.98%) and Group B (21.80%). The percentage of correct answers among the Bologna trainee nurses were always significantly lower than that of the San Marino nurses., Conclusions: These results suggest a scant awareness and interest in ARP among trainee nurses and show that courses and lectures are more effective than scientific printed material.

Background/aims: To evaluate the tolerability and therapeutic potential of the immunostimulating adjuvant alpha-1-thymosin in patients with hepatocellular carcinoma., Methodology: Twelve patients with hepatocellular carcinoma were treated with alpha-1-thymosin (900 micrograms/m2 subcutaneously twice per week for 6 months) and transcatheter arterial chemoembolization and compared to a historical control group (matched for gender, age, Okuda staging, Child's score, alpha-fetoprotein serum levels and viral infection) treated with transcatheter arterial chemoembolization alone., Results: No severe side effects were recorded in the 2 treatment groups. The combination of alpha-1-thymosin plus transcatheter arterial chemoembolization resulted in a longer survival that reached statistical significance 7 months after the end of treatment (p < 0.05). Patients receiving combined treatment demonstrated a significant increase in peripheral blood mononuclear cells expressing CD3 (p < 0.05) and CD8 (p < 0.025) 3 months after beginning treatment. They also had a significant increase (p < 0.05) in CD16+ and CD56+ cells after 1 month, and a slight reduction in mononuclear cells expressing CD25, a marker for cell activation. No alterations in the response to phytohemagglutinin stimulation were seen during the alpha-1-thymosin treatment., Conclusions: The absence of toxicity and the favourable effects observed in this open study call for a double blind control study to confirm the efficacy of the combined treatment.

Background/aims: Liver transplantation for alcoholic end-stage liver disease remains controversial at many transplant centers. The aim of the present study was to evaluate the outcome of patients with alcoholic liver disease who underwent liver transplantation at Centro Trapianti, Policlinico S. Orsola, Bologna., Methodology: We describe the outcomes of 18 alcoholic patients with end-stage liver disease who received orthotopic liver transplants at our center from April, 1986 to February, 1996. The data obtained was compared with that of 114 patients with virus-related cirrhosis selected as transplant controls. An absolute period of abstinence from alcohol consumption for at least six months was required., Results: Regarding the actuarial survival rate and non-fatal post-transplant complications, no significant differences were noted in comparing the non-alcoholic with the alcoholic recipients, except for a higher incidence of Cytomegalovirus infection in the alcoholic group followed-up for more than four months. The alcoholic relapse rate was 27.2%, but only one patient returned to harmful drinking. Seventy-three percent of subjects who were followed-up for at least six months were occupied in gainful employment. Alcoholic relapse did not affect employment status., Conclusion: This data demonstrates that liver transplantation for selected patients with end-stage alcohol-related cirrhosis achieves good results in survival, complications and employment status, and it appears difficult to defend an inflexible claim to have demonstrated an absolute long-term abstinence before transplantation when a severe deterioration of liver function is present.

Background/aims: The gastrointestinal tract is directly affected by the ingestion of alcohol. While the effect of acute ingestion of alcohol on the motility of the small intestine is well known, the influence of chronic intake of moderate amounts of alcohol and chronic alcoholism on gastrointestinal motility remains poorly understood. The aim of this study was to examine the orocecal transit (OCt) times in patients with chronic alcoholism and in "social drinkers" and compare them with a group of healthy teetotaler subjects, to assess the effects of chronic aleohol consumption on gastrointestinal transit through the application of a non-invasive technique: the hydrogen breath test., Methodology: Thirty-one alcoholics were enrolled in the study. The control groups consisted of 31 healthy social drinkers and 24 healthy teetotaler subjects. OCt time was assessed using the hydrogen breath test after the administration of 10 g of lactulose., Results: The OCt time in patients with alcoholism was significantly delayed as compared with the social drinkers (p < 0.001) and healthy teetotaler subjects (p < 0.001); the OCt time in social drinkers was significantly longer than in healthy teetotaler subjects (p < 0.05). In the alcoholic group, there was no significant correlation between the OCt time and daily alcohol intake or years of alcohol addiction., Conclusion: Our results show a significant prolongation of the OCt time, both in patients with alcoholism and in social drinkers, as compared to teetotaler subjects. Our findings of an increased OCt time related to the consumption of alcohol could support the hypothesis of the toxic effect of ethanol on smooth muscle contractile proteins of the small intestine and on vagal function.

Background/aims: Psychiatric illness and psychological behavioral pathologies may be present in celiac disease and in IBD patients. In these subjects anxiety and depression could be a main cause in the reduction of the compliance to the treatment. Aim of our study was to carry out a psychometric evaluation using appropriate means to determine the level of anxiety and depression and to distinguish between "state" and "trait" forms. The correction of such disturbances would improve the quality of life and the patients' compliance to treatment., Material and Methods: Sixteen adult celiac patients, 16 subjects affected by IBD and 16 healthy control subjects matched for sex, residence and marital status were studied by psychological assessment. All the subjects were given the State and Trait Anxiety Inventory and the Ipat Depression Scale Questionnaire., Results: State anxiety was present in a higher percentage of celiac subjects and in the patients affected by IBD with respect to the healthy controls. Anxiety as a trait was present in a similar percentage in all the subjects evaluated. Depressive syndrome was present in a percentage of celiac patients statistically superior versus the healthy control group (p < 0.01)., Conclusion: Our results shown that anxiety is present as a "reactive" form and personality trait anxiety has no effect in celiac and IBD patients. As regard depression, our data confirm a possible linkage between brain functions and malabsorption.

Primary graft non-function remains one of the most life-threatening problems after liver transplantation. Its etiology is still unclear. Liver retransplantation is the only therapeutic alternative to this problem. The PGE1 series of prostaglandins have recently been successfully used in the treatment of transplanted organ dysfunction. In this paper we describe a case of primary graft non-function successfully treated with continuous infusion of prostaglandin PGE1, and we briefly discuss the pathogenetic and therapeutic hypotheses.
