Objective: Focal renal lesions are common incidental findings on computed tomography (CT). For lesions with a cystic appearance, the Bosniak classification system has enabled an important separation of benign and (potentially) malignant cysts, giving a practical guide for management. The purpose of this study was to evaluate contrast-enhanced ultr...

Permanent and reliable vascular access is of utmost importance for patients (with chronic renal failure) in need of haemodialysis. Autogenous arteriovenous fistula (AVF) on the forearm are robust and have the benefits of providing long-term access with relatively few complications. The main problem is insufficient blood flow due to stenoses requiri...

In order to avoid complications in temporal arteritis, early diagnosis and start of treatment is essential. In many cases, however, the symptoms and clinical signs are non-specific. Surgical biopsy has disadvantages, and false-negative results occur. The use of colour Doppler sonography in the diagnosis of temporal arteritis is described, based on...

Acute renal failure due to bilateral ureteral obstruction is a rare complication after appendectomy in children. We report a case of anuria in an 11-year-old boy five days after surgery for a perforated acutely inflamed appendix. No abscess was found with CT. After saline-filling of the urinary bladder, transabdominal ultrasound demonstrated echoge...

The role and benefit of percutaneous transluminal angioplasty (PTA) for treatment of arteriosclerotic lesions in the crural arteries has been controversial. The purpose of this study was to review our experience. 88 patients were treated with PTA for stenoses and/or occlusions of the popliteal or crural arteries. The indications were disabling clau...

Background. The diagnosis of renal artery stenosis is based on a clinical evaluation and imaging of selected patients. Angiography is still the gold standard, but several non-invasive modalities like renography, CT angiography, MR angiography and Doppler sonography are used. Today there is no consensus on what is the optimal modality. Material and...

Oral intake of the mushroom Psilocybe semilanceata, with the intent to achieve hallucinations appears to be occurring in various places in Norway. The aim of this paper is to present two case reports, to describe the mushroom and its active chemical substances, and to give an account of the clinical symptoms following intoxication. A brief note on...
