There are about 25560 clinical studies being (or have been) conducted in Germany. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
For patients with emphysema, lung volume reduction by insertion of endobronchial valves could be an expedient approach to improve the diaphragm function and the strength of breathing muscles. Therefore in the present study investigators intend to examine, whether the lung volume reduction by valves might improve the physical capacity and the quality of life.
The purpose of this study is to examine whether there are relations between different types of pain in groups of patients with different diagnoses of degenerative diseases of the spinal column and their related surgeries.
During neurosurgical resection of brain tumors within brain areas for motor control, it is important to monitor motor function. For this muscle motor evoked potentials are used. Those are elicited by transcranial and direct cortical stimulation. Motor responses are recorded from muscles. In neurosurgical procedures for spinal cord tumors, the same methods are used, but additionally motor activity is recorded from the spinal cord. This is called spinal motor evoked potentials. It is known that the relation between spinal and muscle motor evoked potentials helps to extent the resection of spinal cord tumors. This study implements the spinal motor evoked potential into brain tumor surgery and analyses the relationship between spinal and muscle motor evoked potentials. With this, detection of injury to the brain area for motor control might be discovered earlier and thus tumor resection can be performed safely.
Endoscopic ultrasonography (EUS ) -guided fine needle aspiration (EUS -FNA ) of focal pancreatic lesions is an essential diagnostic procedure with high therapeutic effect in clinical routine. The aim of this study is to determine the levels of serum lipase, serum amylase and the tumor marker CA 19-9 prior and after EUS-FNA. In animal experiments on dogs, an increase of all three parameters was observed after surgery on the pancreas. For humans, these clinically important data are not yet available . It is assumed that the probability of pancreatitis with increased activity of lipase and amylase will rise with the number of puncture procedures as well as the size of the puncture needle. In addition, the post-interventional assessment of the tumor marker CA 19-9 could result in a false positive assumption of malignant neoplastic pancreatic lesion.
To study the effect of combined tDCS plus speech therapy compared to sham-tDCS plus speech therapy in subacute stroke patients suffering from moderate or severe aphasia. The patients will be randomized by a computer-generated lot. Assessment will be performed at study onset, after six weeks at the end of the specific intervention and 4 months after stroke onset for follow-up.
Patients with glioblastoma face a grim prognosis. Despite recent advancement in neurosurgical technology and neuro-oncology glioblastomas almost invariably progress or recur after a median of 4-8 months. The strategy to repeat tumor resection at recurrence in order to minimize tumor load and thus to facilitate subsequent second-line therapy has been shown to be feasible and safe. However, evidence for a survival benefit of surgery for recurrent glioblastoma is scarce and relies entirely on retrospective analyses. While most retrospective analyses report an apparent survival benefit, an EORTC meta-analysis on second-line therapies found no survival difference in patients with or without surgery at recurrence. With regard to the risks and costs inherent to surgery for glioblastoma, a randomized controlled trial is required. The purpose of the study is to compare the effect of craniotomy and tumor resection followed by adjuvant second-line therapy to no surgery followed by second-line therapy on overall survival, neurological status, and quality of life. Analysis of overall survival will be used to improve sample size estimation of a subsequent phase III trial for craniotomy and tumor resection of glioblastoma recurrence in cooperation with the EORTC.
The relation between burst and suppression periods in transcranial and direct cortical recorded EEG with cortical amplitudes median nerve somatosensory evoked potentials is studied. 60 patients are included in this study: 15 patients undergoing brain tumor surgery, 15 spine surgery (University Hospital Düsseldorf) and 30 patients during general surgical procedures (Helios Klinikum Wuppertal).
This is a controlled, randomized, single-blinded, multicenter, prospective clinical study. In addition to the standard periodontal treatment procedure on all teeth that need to be treated, the 4 teeth with the deepest pockets (between 4 and 6 mm) will be randomized to either PERIOSYAL® FILL and oral hygiene or oral hygiene alone. The pocket depth will be measured at six sites around each tooth, and only the deepest pocket sites of each tooth will be taken into account.
This trial examines the feasibility and toxicity of focal brachytherapy in patients with low-risk prostate cancer.
As recommended in the Guidelines on the prevention, diagnosis, and treatment of infective endocarditis (IE) patients with IE should be evaluated and managed by a multispecialty team including an cardiologist, infectious disease specialist, and cardiac surgeon. Our registry is a prospective, national registry of patients with IE. From January 2013 data from endocarditis board were prospectively recorded using standard definitions during the hospitalization. Patient demographics, clinical, laboratory, and imaging data at the time of IE diagnosis, as well as treatment outcomes were entered into the ER-UHC database.
