For the management of severe haemoptysis we have developed a double-lumen, bronchus-blocking catheter that can be introduced through the working channel of a standard fibrebronchoscope. We wondered whether this catheter would be suitable to control pulmonary haemorrhage in clinical practice. Over a period of 36 months, 30 of these catheters were used in 27(More)
INTRODUCTION Besides conventional colonoscopy, CT and MR colonography offer alternate virtual imaging modalities of the colon. The sensitivity of CT colonography, which is associated with radiation exposure, has been published in prior, large studies. Regarding MR colonography, in particular dark lumen MR colonography with the rectal administration of a(More)
During the past decade, multi-touch surfaces have emerged as valuable tools for collaboration, display, interaction, and musical expression. Unfortunately, they tend to be costly and often suffer from two drawbacks for music performance: (1) relatively high latency owing to their sensing mechanism , and (2) lack of haptic feedback. We analyze the la-tency(More)
Dissecting aneurysm of the pulmonary artery is a rare (1 : 3000) but life threatening complication of the use of Swan-Ganz catheters. The most typical clinical manifestation is hemoptysis, even a asymptomatic aneurysm causes pathognomonic X-ray findings. The eventually long free intervall between catheterisation and formation of the dissecting aneurysm(More)
In Anomalous Pulmonary Venous Drainage one or more pulmonary veins are not connected with left atrium, but drain into systemic circulation or right atrium. The clinical signs of the shunt between pulmonary and systemic circulation increase during lifetime, thus the abnormality gets late or not diagnosed. Partial Anomalous Pulmonary Venous Drainage is a(More)
A 51-year-old female hospitalized with a non-specific colitis, presented a crescent-like shadow in the right lower lung accompanied by a reduced right lung volume on a routine chest x-ray. There was no family history of congenital heart disease. The initially performed, noninvasive, contrast enhanced cardiac CT (electron-beam tomography [EBT]) proved the(More)
