Functional MRI and motor behavioral changes obtained with constraint-induced movement therapy in chronic stroke

2011

Background:  The clinical benefits of intensive stroke rehabilitation vary individually. We used multimodal functional imaging to assess the relationship of clinical gain and imaging changes in patients with chronic stroke whose voluntary motor control improved after constraint-induced movement therapy (CIMT). Methods:  Eleven patients (37.6 ± 36.8 months from stroke) were studied by functional MRI (fMRI), transcranial magnetic stimulation (TMS), and behavioral assessment of hand motor control (Wolf Motor Function Test) before and after 2 weeks of CIMT. Individual and group-level changes in imaging and behavioral parameters were investigated. Results:  Increase in fMRI activation in the sen…

Morphologische und funktionelle Evaluation pulmonaler Gefäßanomalien mittels schneller MR-Techniken

2002

Purpose: To evaluate breath-hold MR techniques for morphologic and functional assessment of vascular abnormalities of the pulmonary vasculature. Patients and Methods: 13 patients aged 11 to 60 years with different vascular abnormalities of the pulmonary vasculature (5 patients with 16 arteriovenous malformations, 8 patients with partial anomalous pulmonary venous return) underwent MR imaging at 1.5 T. For morphological assessment, a contrast-enhanced 3D MR angiography (ce-MRA) was performed after a timing run. Segmented cine- and velocity-encoded GRE sequences were used for delineation of associated cardiac septal defects and for determination of systemic left-to-right or intrapulmonary shu…

The Sum of ST-Segment Elevation Is the Best Predictor of Microvascular Obstruction in Patients Treated Successfully by Primary Percutaneous Coronary …

2010

Introduction and objectives The usefulness of ST-segment elevation resolution (STR) for predicting epicardial reperfusion is well established. However, it is still not clear how ST-segment changes are related to microvascular obstruction (MVO) observed by cardiovascular magnetic resonance (CMR) after primary percutaneous coronary intervention (pPCI) for ST-segment elevation myocardial infarction (STEMI). Methods The study involved 85 consecutive patients admitted for a first STEMI and treated by pPCI who had a patent infarct-related artery. An ECG was recorded on admission and 90 min and 6, 24, 48 and 96 h after pPCI. Thereafter, STR and the sum of ST-segment elevation (sumSTE) in all leads…

Adrenal gunshot wound: Laparoscopic approach. Report of a case

2013

introduction: Although there is no debate that patients with peritonitis or hemodynamic instability should undergo urgent laparotomy after penetrating abdominal injury, it is also clear that certain stable patients may be managed without operation. Controversy persists regarding use of laparoscopy. PRESENTATION OF CASE: We report a case of gunshot wounds with bullet in left adrenal gland and perirenal subcapsular hematoma. The patients had no signs of peritonitis but in the observation period we noted a significative blood loss, so we performed an exploratory laparoscopy. DISCUSSION: We found the bullet in adrenal parenchyma. The postoperative period was regular and the patient was discharg…

Chylous ascites after lymphadenectomy for gynecological malignancies

2016

Background and Objectives Chylous ascites, an accumulation of milky-white lymph fluid in the peritoneal cavity, is a rare complication following retroperitoneal lymphadenectomy. This study evaluated the appearance and management of chylous ascites following lymphadenectomy for gynecological malignancies. Methods A total of 931 patients who underwent lymphadenectomy for gynecological malignancies at Erlangen University Hospital between 2002 and 2013 were reviewed retrospectively. Results Chylous ascites occurred postoperatively in 28 of the 931 patients (3.0%). All patients with chylous ascites had undergone combined systematic para-aortic and pelvic lymphadenectomy (SAPL). Patients with chy…

Angiographic follow-up results of a randomized study on angioplasty versus bypass surgery (GABI Trial)

1996

Although several randomized trials have been performed to compare the outcomes of percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass surgery (CABG) in patients with multivessel disease, there is little data available on angiographic follow-up results. The present substudy of the German angioplasty versus bypass surgery investigation (GABI Trial) compares the angiographic revascularization status in these two cases 6 months after treatment. Follow-up angiograms were available in 102 CABG patients and 117 PTCA patients. Although the protocol excluded patients with total occlusion, on follow-up 6 months after treatment we found total occlusion of 94 native arterie…

Klassifikation und Therapie von Endolecks nach endovaskulärer Behandlung von abdominellen Aortenaneurysmen

2005

This article describes the classification of endoleaks after endovascular treatment of abdominal aortic aneurysms, thereby summarizing the most important problems of this endovascular technique. The correct classification of endoleaks is a prerequisite for interdisciplinary discussion. It is indispensable for professional reporting of the pathological findings and for the decision making as to the adequate treatment of endoleaks. Irrespective of the types of stent graft and property of the material, five endoleak types are defined in the literature: leakage at the anchor sites (type I); leakage due to collateral arteries (type II); defective stent grafts (type III); leakage due to porosity …

Der hyperplastische Polyp des Magens - eine Präkanzerose?

2002

In general, hyperplastic polyps of the stomach are regarded as benign lesions. Still there is the chance to find carcinomas within them as documented in this case report. This finding can be interpreted as an incidental appearance. At the moment there are no standardized guidelines regarding diagnostics and therapy of gastric hyperplastic polyps. Referring to a short review of the literature endoscopic snare polypectomy seems to be a reasonable therapeutic option of hyperplastic polyps with a size of 0.5-1 cm. Although it is possible to determine the histology by forceps biopsy, it is possible to be misled by missing areas of focal carcinomas. Complications after polypectomy are rare and of…

Radiosurgery of Carotid-Cavernous Fistulae

1994

25 cases of carotid-cavernous fistulae (CCF) who underwent radiosurgery with a conventional gamma source from 1977 to 1992 are reported. 22 were low-flow, spontaneous CCFs and 3 were high flow fistulae which had undergone a previous trApplng. The total dose delivered was 30 to 40 Gy. 91% to patients with low-flow CCF cured after radiosurgery in a mean time of 7.5 months, presenting improvent in a mean time of 2.3 months. Only one of the high-flow fistulae was cured. Follow-up period ranged between 14 years and 15 months (mean: 50 months). No recurrence was recorded in any case. While intravascular embolotherapy is the treatment of choice for high-flow fistulae, stereotactic radiosurgery may…

School-age reading skills are associated with and predicted by preschool-age cognitive risk factors for dyslexia, such as deficits in phonological awareness, rapid automatized naming, letter knowledge, and verbal short-term memory. In addition, evidence exists that problems in morphological information processing could be considered a risk factor for dyslexia. In the present study, 27 children at pre-school age and the same 27 children at first grade age performed a morphological awareness task while their brain responses were measured with magnetoencephalography. Our aim was to examine how derivational morphology in Finnish language, and concomitant accuracy and reaction times are associat…
