- Purpose In medical schools small specialties like clinical pharmacology may be integrated in courses covering larger specialties and examined concomitantly. The results of a pilot study suggested that this approach would have negative consequences on the knowledge gained in clinical pharmacology with integration of this speciality in the course of internal medicine and concomitant examination. The aim of the present study was to assess in more detail whether students’ presumed tendency to study selectively influences approval (the pass mark), a surrogate marker of the knowledge gained. Methods A written examination for the integrated course in clinical pharmacology and internal medicine in Gothenburg, Sweden, was specifically designed in 2008 to evaluate the research question. The examination consisted of 50 short answer questions, of which five focused on clinical pharmacology (maximum score 10) and 45 were on internal medicine (maximum score 90). The cut-off level for approval (pass mark) was 60 %. Results Of the 81 students who wrote the examination, 73 (90.1 %) passed the examination as a whole. When the questions in clinical pharmacology were assessed separately, 62 (76.5 %) students passed the cut-off level of 60 %; the corresponding proportion of students achieving the cut-off level for questions on internal medicine was 90.1 %. There was a significant correlation between the results of the two specialties (p<0.001), but the questions on clinical pharmacology generated lower scores (p<0.001). The correlation coefficient between the results of two randomly chosen questions for clinical pharmacology was greater than that of two randomly chosen questions in internal medicine (p<0.001). Conclusions Our results confirm that a small specialty like clinical pharmacology may need to be examined separately in order to guarantee a sufficient level of knowledge among students.

- Objective. The information concerning the morbidity and mortality of hereditary hemochromatosis is based primarily on clinical cohorts of symptomatic patients. The major aim of this study was to analyze the long-term prognosis for Swedish patients with this condition, with respect to both clinical features and survival, in relation to the route by which the disease was detected. Patients and methods. 373 patients with hemochromatosis detected through routine health checkups (n = 153), family screening (n = 44), symptoms of arthralgia (n = 23), investigation of other diseases/symptoms (n = 108) or signs of liver disease (n = 45) were monitored for a mean period of 11.9 +/- 5.8 years. The degree of liver fibrosis and survival were analyzed. Results. Overall survival among these patients was not significantly different from that of a matched normal population. The patients diagnosed through health check-ups and family screening were detected at an earlier age and had the highest rate of survival. Liver biopsy at the time of diagnosis revealed cirrhosis in 9% of those detected through the health check-ups and 5% in the case of family screening, compared with 13% for the group with arthralgia, 17% for other diseases/symptoms and 42% for liver disease. Conclusion. Health check-ups and family screening allow detection of hereditary hemochromatosis at an earlier age and with less advanced liver fibrosis, although a few of these patients have already developed cirrhosis. Our study indicates that iron indices should be included in health check-ups, and if abnormal, should lead to further investigation.

- BACKGROUND & AIMS: Corticosteroids alone or in conjunction with azathioprine (AZA) is the standard treatment in autoimmune hepatitis (AiH). Individual variations in thiopurine (TP) metabolism may affect both drug efficacy and toxicity. Our aim was to investigate the utility of thiopurine methyltransferase (TPMT) as well as thioguanine nucleotide (TGN) and methylthioinosine monophosphate (meTIMP) metabolite measurements with regard to clinical outcome. METHODS: Two hundred thirty-eight patients with AiH were included in this cross-sectional study. TPMT status was assessed in all patients, while TGN and meTIMP were measured in patients with ongoing TP medication. Clinical outcome was evaluated by liver tests and the ability to withdraw steroids. RESULTS: TPMT genotyping (n=229) revealed 207 (90.4%) wild-type and 22 heterozygous patients. One hundred forty-three patients had ongoing TP therapy with AZA (n=134) or mercaptopurine (MP; n=9); response was judged as complete response (CR) in 113 patients and partial response (PR) in 30 patients. Both TP dose (1.64 vs 1.19mg/kg; p=0.012) and TPMT activity (14.3 vs 13.5; p=0.05) were higher in PR, resulting in similar TGN levels (PR: 121pmol/8x10(8) red blood cells [RBC]; CR: 113pmol/8x10(8) RBC; p=0.33) but higher meTIMP levels in PR (1350 vs 400pmol/8x10(8) RBC; p=0.004). Patients able to withdraw steroids or who were using 5mg prednisolone daily were treated with lower TP doses than patients on higher steroid doses (1.15 vs 1.18 vs 1.82mg/kg; p<0.001). CONCLUSIONS: TP metabolite measurements are of clinical value in AiH patients who do not respond to standard TP treatment and for the identification of a shifted metabolism, which may demand an alternative treatment strategy.

- Objective. Development of ascites in patients with liver cirrhosis is an ominous sign with a poor outcome. A liver transplantation must be considered, and it then becomes important to know if there are any factors indicating a worsened prognosis. Material and methods. We used official registers for a follow-up study of at least 5 years considering the prognosis of 155 prospectively recruited in-patients with cirrhotic ascites from medical units at nine Swedish university hospitals. All patients had undergone at least one diagnostic ascites tap, and had initially been questioned about background factors and physically examined according to a standardized case record form, followed by sampling of blood, urine, and ascites. Results. Death occurred within 1 year after inclusion in 53% of the cases, and was primarily liver-related in 70%. In a multivariable analysis, the two ordinary variables that showed the strongest correlation with risk of death were serum potassium and abdominal tenderness. All 22 patients with a serum potassium concentration of at least 4.8 mmol/L (maximum 5.8 mmol/L) died within 1 year after inclusion. Potassium concentration was related to renal function and potassium-saving drugs. Conclusion. This follow-up study of a prospectively recruited cohort of in-patients with cirrhotic ascites confirms their poor prognosis. Awareness of an elevated serum potassium value, which would reflect a threatened renal function, seems essential, because it may offer a simple way to identify cases with the worst prognosis. An area for further research should be to explore the significance of including serum potassium in prognostic models.

- Purpose, The present article was built on the assumption that the form of an examination may influence learning, and may also reflect different kinds of knowledge. The aim of the study was to evaluate whether the results of an examination differ when short answer questions (SAQ) or modified essay questions (MEQ) are used. Method, Forty-nine students in the internal medicine course in Gothenburg, Sweden, performed a written examination in 2003, which included both SAQ and MEQ. Result, The correlation between the results of SAQ and MEQ was 0.59 (P < 0.001). The percentage correctly answered questions in the two types did not differ significantly. Some students had poor results in either SAQ or MEQ. Conclusion, The general outcome of the study indicates that results of SAQ and MEQ demonstrate a significant correlation. However, they may also reflect differences in mastery of the knowledge domain, which should be considered in relation to aspects of validity

- Objectives. Autoimmune hepatitis (AIH) is a liver disease which, if untreated, may lead to liver cirrhosis and hepatic failure. Limited data exist regarding factors predicting the long-term outcome. The aims of this study were to investigate symptoms at presentation, prognostic features, management and treatment in relation to long-term outcome of AIH. Material and methods. A cohort of 473 Swedish patients with AIH was characterized regarding initial symptoms and signs, factors predicting death and future need for liver transplantation. Survival and causes of death were retrieved from Swedish national registers. Results. At diagnosis, fatigue was a predominant symptom (69%), 47% of the patients were jaundiced and 30% had liver cirrhosis. Another 10% developed cirrhosis during follow-up. Markedly elevated alanine aminotransferase levels at presentation were correlated with a better outcome. A high international normalized ratio (INR) at diagnosis was the only risk factor predicting a need for later liver transplantation. Histological cirrhosis, decompensation and non-response to initial treatment were all factors that correlated with a worse outcome. Overall life expectancy was generally favourable. However, most deaths were liver-related, e.g. liver failure, shock and gastrointestinal bleeding. Conclusions. Cirrhosis at diagnosis, a non-response to initial immune-suppressive treatment or elevated INR values were associated with worse outcome and a need for later liver transplantation. In contrast, an acute hepatitis-like onset with intact synthetic capacity indicated a good response to treatment and favourable long-term prognosis. Lifetime maintenance therapy is most often required.

- BACKGROUND: Reliable epidemiological data for portal vein thrombosis are lacking. AIMS: To investigate the incidence, prevalence and survival rates for patients with portal vein thrombosis. METHODS: Retrospective multicentre study of all patients registered with the diagnosis of portal vein thrombosis between 1995 and 2004. RESULTS: A total of 173 patients (median age 57 years, 93 men) with portal vein thrombosis were identified and followed up for a median of 2.5 years (range 0-9.7). The mean age-standardized incidence and prevalence rates were 0.7 per 100,000 per year and 3.7 per 100,000 inhabitants, respectively. Liver disease was present in 70 patients (40%), malignancy in 27%, thrombophilic factors in 22% and myeloproliferative disorders in 11%. Two or more risk factors were identified in 80 patients (46%). At diagnosis, 65% were put on anticoagulant therapy. Thrombolysis, TIPS, surgical shunting and liver transplantation were performed in 6, 3, 2 and 8 patients, respectively. The overall survival at 1 year and 5 years was 69% and 54%. In the absence of malignancy and cirrhosis, the survival was 92% and 76%, respectively. CONCLUSIONS: The incidence and prevalence rates of portal vein thrombosis were 0.7 per 100,000 inhabitants per year and 3.7 per 100,000 inhabitants, respectively. Concurrent prothrombotic risk factors are common. The prognosis is variable and highly dependent on underlying disease.
