111-Indium-DTPA-Octreotid-Szintigraphie bei kolorektalen Lebermetastasen
1997
The somatostatin analogue octreotide is effective in the treatment of neuroendocrine and other tumours. 111-In-labelled DTPA-octreotide scintigraphy is successful in localizing primary neuroendocrine tumours and metastases and other tumours containing somatostatin receptors. An antiproliferative effect of octreotide was also demonstrated for colorectal carcinoma. Since only about 40% of colorectal carcinomas express somatostatin receptors, we tried to establish whether 111-In-labelled DTPA-octreotide scintigraphy is able to reveal the receptor status of liver metastases in patients with colorectal liver metastases. This would be useful in selecting patients for adjuvant therapy studies with…
Diagnostische Möglichkeiten und Behandlungsstrategien für die Fraktur der Eminentia intercondylica im Wachstumsalter
1995
Between 1970 and 1993 29 fractures of the intercondylar eminence were seen in children with almost the same number of cases showing no or minor displacement as those requiring open reduction for major dislocation. Combined knee injury must be suspected the higher the patient's age and the more pronounced the displacement of the fragment. Magnetic resonance imaging (MRI) has gained diagnostic predominance. Arthroscopy remains important for surgical management, especially of associated meniscus and cartilage damage. Early puncture of hemarthrosis is essential. Closed management is the therapy for nondisplaced fragments or those with bone contact or only tuberculum fractures--while displaced f…
Randomized clinical trial comparing liver resection with and without perioperative assessment of liver function
2018
Background Liver function tests may help to predict outcomes after liver surgery. The aim of this study was to evaluate the clinical impact on postoperative outcome and patient management of perioperative liver function testing using the LiMAx® test. Methods A multicentre RCT was conducted in six academic liver centres. Patients with intrahepatic tumours scheduled for open liver resection of at least one segment were eligible. Patients were randomized to undergo additional perioperative liver function tests (LiMAx® group) or standard care (control group). Patients in the intervention arm received two perioperative LiMAx® tests, one before the operation for surgical planning and another afte…
An FFR CT diagnostic strategy versus usual care in patients with suspected coronary artery disease planned for invasive coronary angiography at Germa…
2017
Aim Diagnostic evaluation practices for suspected coronary artery disease (CAD) may vary between countries. Our objective was to compare a CT-derived fractional flow reserve (FFRCT) diagnostic strategy with usual care in patients with planned invasive coronary angiography (ICA) enrolled in the PLATFORM (Prospective Longitudinal Trial of FFRCT: Outcome and Resource Impacts) study at German sites. Methods Patients were divided into two consecutive observational cohorts, receiving either usual care or CT angiography (CTA)/FFRCT. The primary endpoint was the percentage of patients planned for ICA, with no obstructive CAD on ICA within 90 days. Secondary endpoints included death, myocardial infa…
Das Popliteaaneurysma: Klinik und Diagnostik
1995
PURPOSE To identify clinical and radiological features allowing an early diagnosis of popliteal aneurysms. MATERIAL AND METHODS History, clinical features and radiological findings of 23 patients with 37 aneurysms were reviewed. RESULTS 14 patients presented with a history of a sudden onset of rest pain localised in the calf or foot. Arteriography found popliteal artery occlusion in 12 of them. Amputation was necessary in one patient in spite of immediate diagnosis and therapy. In two cases embolisation of the tibial vessels caused intermittent claudication. In at least 7 patients the underlying disease was not suspected until arteriography was performed. In 16/23 patients the presence of t…

Both daily demands as well as training and competition characteristics in sports can result in a psychobiological state of mental fatigue leading to feelings of tiredness, lack of energy, an increased perception of effort, and performance decrements. Moreover, optimal performance will only be achievable if the balance between recovery and stress states is re-established. Consequently, recovery strategies are needed aiming at mental aspects of recovery. The aim of the study was to examine acute effects of potential mental recovery strategies (MR) on subjective-psychological and on cognitive performance outcomes after a mentally fatiguing task. A laboratory-based randomized cross-over study w…

Interruptions (interfering stimuli to respond to) and distractions (interfering stimuli to be ignored) have been shown to negatively impact performance, particularly in tasks requiring working memory (WM). This study investigated how these two types of external interference affect task performance and attentional and WM processes as indexed by specific event-related potentials (ERPs) of the EEG. A Continuous Number Task (CNT) was applied, in which participants had to either decide whether the current number (condition without WM load) or the sum of the current and the preceding number (condition with WM load) was odd or even while responding to interlaced single letters (interruptions) or i…
MindBEAGLE — A new system for the assessment and communication with patients with disorders of consciousness and complete locked-in syndrom
2017
Patients with disorders of consciousness (DOC) cannot reply to questions or clinical assessments using voluntary motor control, and therefore it is very difficult to assess their cognitive capabilities and conscious awareness. Patients who are locked-in (LIS) are instead fully conscious, and they can communicate with their preserved eye movements. However, when the residual oculomotor activity is also lost (e.g., patients with amyotrophic lateral sclerosis disease of very long duration), the locked-in status becomes complete (CLIS). In CLIS patients, detection of conscious awareness may become very challenging, similarly to the subjects with DOC. mindBEAGLE has a physiological testing batte…
Results of endoscopic retroperitoneal adrenalectomy
1996
Background: From March 1994 to August 1995 we performed extraperitoneal endoscopic adrenalectomy in 18 patients with adrenal gland tumors. Methods: Two of these patients underwent bilateral adrenalectomy. For the extraperitoneal approach a pneumoret-roperitoneum was established and three 10-mm trocars were inserted in the area of the conventional flank incision. Adrenalectomy was performed via these ports. Endoscopic retroperitoneal adrenalectomy was successful in 15 patients; three patients required a conventional operation via an extraperitoneal lumbar approach because of inadequate exposure of the adrenal gland. In patients with endoscopic retroperitoneal adrenalectomy median operative t…
Clinical significance of the quantitative and qualitative determination of the cerebral blood flow through the use of isotopes
1966
Es wird über die bisher entwickelten Methoden zur bestimmung der Hirndurchblutung mit radioaktiven Isotopen berichtet, wobei die quantitativen Untersuchungsmethoden hinsichtlich ihrer klinischen Bedeutung den qualitativen gegenübergestellt werden. Während die quantitativen Methoden eine genaue Bestimmung des cerebralen Blutvolumens und damit der Gesamtdurchblutung des Hirns bzw. bestimmter Hirnareale ermöglichen, bieten die qualitativen Untersuchungsmethoden hinsichtlich der klinisch-diagnostischen Aussagekraft besondere Vorteile. Aus der Bestimmung der Zirkulationszeit des Hirns und dem Verlauf der über beiden Hemisphären registrierten Aktivitätskurven lassen sich differenzial-diagnostisch…
