Background: Cystic echinococcosis is a zoonosis caused by the parasite Echinococcus granulosus. The disease rarely occurs in Norway, but constitutes a significant global health issue.

Case Presentation: A man in his forties presented with right-sided flank pain.

Background: Attenuation is correlated with the concentration of contrast medium (CM) in the arteries. The cardiac output (CO) affects the concentration of CM in the circulatory system; therefore, CO affects the time-density curve (TDC). Thus, estimating CO using TDC from test-bolus images acquired in computed tomography (CT) is possible.

Background: Neuropsychiatric manifestations (NP) are common in systemic lupus erythematosus (SLE). However, the pathophysiological mechanisms are not completely understood. Neurofilament light protein (NfL) is part of the neuronal cytoskeleton.

Background And Methods: Treatment strategies for pancreatic cancer patients are made by a multidisciplinary team (MDT) board. We aimed to assess intra-observer variance at MDT boards. Participating units staged, assessed resectability, and made treatment allocations for the same patients as they did two years earlier.

Background: To test the hypothesis that neurofilament light (NfL) in CSF is a biomarker of CNS involvement in patients with systemic lupus erythematosus (SLE) and primary Sjögren's syndrome (pSS), we measured NfL in CSF from 52 patients with lupus and 54 with pSS and explored associations with clinical, structural, immunological and biochemical abnormalities.

Methods: In CSF, we measured NfL, anti-P antibodies, protein S100B and TWEAK by ELISA and anti-NR2 antibodies by electrochemiluminescence. Anti-phospholipid antibodies and routine immunological tests were performed in blood.

While urgent percutaneous cholecystostomy (PC) was introduced as an alternative to acute surgical treatment for acute cholecystitis (AC), the current place of PC in the treatment algorithm for AC is challenged. We evaluate demographics and outcomes of PC in routine clinical practice in a population-based cohort.Retrospective evaluation of consecutive patients treated with PC for AC between 2000 and 2015.

Background: Recent cross-sectional studies have suggested a dose-dependent relationship between lifelong exposure to physical activity and the burden of calcified coronary artery disease (CAD). No longitudinal studies have addressed this concern.

Hypothesis: Exercise volume is associated with progression of coronary artery calcium (CAC), defined as ≥10 units increase in CAC score.

Background: Sudden cardiac death among middle-aged recreational athletes is predominantly due to myocardial ischaemia. This study examined whether measuring cardiac troponin I and T (cTnI and cTnT) after strenuous exercise could identify occult obstructive coronary artery disease.

Design: Prospective observational study.

Ménétriere´s disease is a rare disorder of the body and fundus of the stomach, characterized by a massive proliferation of the foveolar cells and subsequent excess mucous secretion. This results in hypoproteinemia due to loss of serum proteins across the gastric mucosa. The cause of Ménétriere´s disease is unknown, and due to the irreversible and premalignant character of the disorder, the patients affected have been subdued to gastrectomy as the only curable treatment.

Background: The underlying mechanisms of the exercise-induced increase in cardiac troponins (cTn) are poorly understood. The aim of this study was to identify independent determinants of exercise-induced cTn increase in a large cohort of healthy recreational athletes.

Methods: A total of 1002 recreational cyclists without known cardiovascular disease or medication, participating in a 91-km mountain bike race were included.

Background: Patients with psychiatric conditions are often referred for a brain scan during the course of their diagnostic workup.

Aims: The aim of our study is to determine frequency and type of organic brain pathology, the relationship to age, gender and psychiatric diagnosis.

Method: We investigated magnetic resonance imaging and computed tomography brain scans from consecutively referred patients over a 10-year period (January 2002-December 2011).

Sarcoidosis is characterised by granulomatous inflammation in one or more organs, including the heart. Cardiac sarcoidosis generally has non-specific symptoms, and the disease is often diagnosed at a late stage. The condition is associated with cardiomyopathy and arrhythmia and may be fatal.

Objective: Whether or not chronic fatigue is reflected in structural changes in the brain is a matter of debate. Primary SS (pSS) is characterized by dryness of the mouth and eyes, migrating muscle and joint pain and prominent fatigue. We aimed to investigate whether the severity of fatigue in pSS was associated with cerebral MRI findings.

Background Circulating cardiac troponin levels increase following prolonged intense physical exercise. The aim of this study was to identify participants with highly elevated cardiac troponins after prolonged, high intensity exercise, and to evaluate these for subclinical coronary artery disease. Methods and results Ninety-seven recreational cyclists without known cardiovascular disease or diabetes, participating in a 91 km mountain bike race were included, 74 (76%) were males, age: 43 ± 10 years, race duration: 4.

Objective: The term hepatoid adenocarcinoma (HAC) of the stomach was introduced three decades ago with the observation of high serum α-fetoprotein (AFP) levels in some gastric adenocarcinoma patients. This very rare gastric cancer patient subgroup is likely frequently misdiagnosed.

Material: Two patients who were recently diagnosed with HAC of the stomach at our institution are presented.

Background: Pancreatic tumors in pregnancy are rare but clinically challenging. Careful diagnostic workup, including appropriate imaging examinations, should be performed to evaluate surgery indications and timing . In the present case a diagnosis of an adult pancreatic hemangioma was made.

Objective: Cognitive dysfunction is common in both systemic lupus erythematosus (SLE) and primary Sjögren's syndrome (SS). Antibodies against the NR2 subtype of the N-methyl-D-aspartate receptor (anti-NR2 antibodies) cause hippocampal atrophy and cognitive impairment in mice and have been associated with memory impairment in both patients with SLE and patients with primary SS. In addition, a reduced volume of hippocampal gray matter has been demonstrated in both SLE and primary SS.

Objective: Our understanding of the etiology and pathogenesis of neuropsychiatric involvement in primary Sjögren's syndrome (SS) is incomplete. In systemic lupus erythematosus, it has been reported that antibodies directed against N-methyl-D-aspartate receptor subtype NR2 (anti-NR2) interfere with memory and learning function, as well as mood. This has not been investigated in primary SS; however, the present study was undertaken to advance our understanding of neuropsychiatric involvement in this disease.

Background/objectives: White matter hyperintensities (WMH) in magnetic resonance imaging (MRI) scans of the brain, and orthostatic hypotension (OH) are both common in older people. We tested the hypothesis that OH is associated with WMH.

Objectives: To explore the relationship between white matter hyperintensities (WMH) and the prevalence and course of depressive symptoms in mild Alzheimer's disease (AD) and Lewy body dementia.

Design: This is a prospective cohort study conducted in secondary care outpatient clinics in western Norway.

Subjects: The study population consisted of 77 elderly people with mild dementia diagnosed according to standardised criteria.
