This contribution addresses the following questions: Does unilateral sports-specific strain affect the skeletal system of the athlete? Specifically, can any differences be found in longitudinal growth of the bones of the forearm and hand in professional tennis players between the stroke arm and the contralateral arm? An investigation was conducted involving(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)
In this paper we determine the proximity functions of the sum and the maximum of componentwise (reciprocal) quotients of positive vectors. For the sum of quotients, denoted by Q1, the proximity function is just a componentwise shrinkage function which we call q-shrinkage. This is similar to the proximity function of the l1-norm which is given by(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)
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)
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)
We report a case of parenchymal pulmonary endometriosis in combination with severe endometriosis genitalis externa. The difficulties on the way to final diagnosis are described, also the different possibilities of hormonal treatment that results in ovarian suppression. In our case the patient is without any symptoms since three years using a GnRH-Agonist as(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)
Acute pancreatitis, neuroleptic malignant syndrome (NMS) and epileptic seizures are all known to be rare complications of clozapine-treatment (Steinert et al. 2011, Tenner 2014, Belvederi Murri et al. 2015). For amisulpride, only seven cases with NMS (Belvederi Murri et al. 2015) including one case with seizures (Musshoff et al. 2013) have been described(More)
