An atypical clinical presentation of acute appendicitis in a young man with midgut malrotation
2007
Abstract Midgut malrotation occurs as a result of failure in normal intestinal rotation and fixation during early pregnancy. Pathological conditions reported in the literature involving midgut malrotation predominantly relate to infants and children. In adults malrotation is often revealed as an incidental finding on computed tomography (CT), or the associated altered anatomy can be the cause of atypical clinical symptoms of relatively common intestinal disorders. An unusual presentation of acute appendicitis, with fever and recurrent pain in left iliac fossa is reported. Underlying intestinal malrotation delayed the correct clinical diagnosis of acute appendicitis. It was not until a CT sc…
Möglichkeiten und Grenzen der Spiral-CT bei der Untersuchung von Nierenbeckenkarzinomen
1994
PURPOSE To assess the value of spiral CT in comparison to conventional CT in the staging of renal pelvic carcinoma. PATIENTS AND METHODS 35 patients with renal pelvic carcinoma underwent preoperative CT; conventional technique (n = 21) and spiral CT (n = 14) with the reconstruction of thin sections were compared. RESULTS Non-invasive or minimal invasive tumours (TA, T1, T2) could not be differentiated with either technique. Small, flat tumours (TA) or multicentric tumours may be missed, even if spiral scanning is applied. The separation of local tumour growth from infiltration is significantly improved by spiral CT (12 of 12 patients instead of 18 out of 21 patients with the conventional te…
Chronic cerebrospinal venous insufficiency: current perspectives
2014
This review summarizes the research to date on chronic cerebrospinal venous insufficiency (CCSVI). CCSVI was initially defined as a clinical syndrome comprising stenoses of the internal jugular and/or azygos veins, characterized by collateral venous outflows and reduced cerebral blood flow, and was found primarily in patients with multiple sclerosis. However, the published evidence on CCSVI is very discordant. Catheter venography studies gave a regular picture, with the majority of patients with multiple sclerosis presenting with demonstrable outflow abnormalities in the veins draining the central nervous system. The prevalence of these lesions was over 50%, and even higher (about 90%) when…
Reinfarction Related to PTCA-Induced Coronary Embolism after Successful Thrombolytic Therapy
1989
Coronary embolism originating from residual thrombotic material is one of the complications arising during acute percutaneous transluminal coronary angioplasty (PTCA) in acute myocardial infarction. This case report describes a symptomatic embolization of the right posterolateral and right posterior descending branch during success-ful PTCA of a subtotal stenosis of the midright coronary artery after acute inferior myocardial infarction. Typical ECG signs of reinfarction were recorded. We succeeded in recanalizing these branches by superselective thrombolysis and angioplasty.
PO-0965: Clinical investigation of inter seed attenuation effects in prostate I-125 seed implant brachytherapy

Prescription Depth in Surface Skin Brachytherapy

2014
Background and purpose: A substantial reduction of uncertainties in clinical brachytherapy should result in improved outcome in terms of increased local control and reduced side effects. Types of uncertainties have to be identified, grouped, and quantified. Methods: A detailed literature review was performed to identify uncertainty components and their relative importance to the combined overall uncertainty. Results: Very few components (e.g., source strength and afterloader timer) are independent of clinical disease site and location of administered dose. While the influence of medium on dose calculation can be substantial for low energy sources or non-deeply seated implants, the influence…
