There are about 13332 clinical studies being (or have been) conducted in Netherlands. 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.
Achalasia is a rare neurodegenerative esophageal motility disorder characterized by incomplete lower esophageal sphincter (LES) relaxation, increased LES tone, and aperistalsis of the esophagus leading to dysphagia, regurgitation, and chest pain. therapies for achalasia consist of endoscopic balloon dilatation (EBD) and botulinum toxin injection (EBTI), or surgical Treatment via i Heller Myotomy; surgery is nowadays mostly performed via the laparoscopic approach. Surgical therapy demonstrated superior treatment efficacy compared to EBD and EBTI. Recently, an endoscopic means to perform myotomy via a submucosal tunnel has been developed, namely PerOral Endoscopic Myotomy (POEM). Uncontrolled studies have indicated a symptomatic success rate of >90% for POEM in short term follow-ups.The aim of this study is to compare short and long-term feasibility, safety and efficacy of endoscopic (POEM) with laparoscopic myotomy (Heller myotomy) in the treatment of achalasia.
Objectives 1. To characterize mechanical ventilation practices during general anesthesia for surgery 2. To assess the dependence of intra-operative and post-operative pulmonary complications on intra-operative Mechanical Ventilation (MV) settings
ClarityIQ is a novel X-ray imaging technology, that combines advanced real-time image noise reduction algorithms, with state-of-the-art hardware to reduce patient entrance dose significantly. This is realized by anatomy-specific optimization of the full acquisition chain (grid switch, beam filtering, pulse width, spot size, detector and image processing engine) for every clinical task individually. Furthermore, smaller focal spot sizes, shorter pulses and the introduction of automatic real-time motion compensation in subtraction imaging are used, which are known to positively influence image quality . The final effect on the clinical image quality in peripheral angiography is investigated in this study.
This study will generate comparative data for 0.5-mg ranibizumab using PRN dosing administered with or without adjunctive laser treatment versus laser photocoagulation (the current standard of care) up to Month 6 in patients with visual impairment due to ME secondary to BRVO. Additionally the results of this study will provide long-term (24-month) safety and efficacy data for ranibizumab, administered with or without adjunctive laser treatment in this indication.
In this randomized crossover trial the investigators test whether three different brands of videolaryngoscopes (VLS) exhibit reduced forces on both upper and lower teeth, and compare them with a classic Macintosh laryngoscope blade.
The purpose of this study is to determine whether there is a difference between the diameter, and the cross-sectional area of the right internal in left internal jugular vein in preoperative, mechanically ventilated patients. Secondary the relationship between the internal jugular vein to the common carotid artery will be examined.
There is ample evidence that children treated for a brain tumour (BT) often develop deficits in social and emotional functioning. The investigators wish to examine the cause of these deficits, i.e. the underlying neuropsychological deficit(s). The aim is to study impairment and developmental delay in social cognition (and related cognitive functions) caused by brain damage in patients treated for a BT in childhood as compared to a reference group of chronically ill children. If we can identify the specific deficits these patients experience, neuropsychological treatment and guidance can be developed to give patients the most optimal chances to live as normal as possible, to improve their quality of life (QoL) and to prevent them from developing depression and anxiety. Eventually, an intervention programme could be developed based on our results, to improve social, vocational and emotional QoL.
The goal of the study is to investigate the use of bio-impedance spectroscopy in the assessment of breast cancer related lymphoedema in patients operated with lumpectomy or mastectomy, axillary lymph node dissection and radiotherapy compared to inverse water volumetry. As a control group, patients with colon rectal cancer are used to compare volumetric and spectometric changes during follow-up.
Arnica ointment is currently used in homeopathic preparations for strains and bruises. In the field of plastic surgery, some surgeons advise patients undergoing blepharoplasty to use Arnica in order to prevent postoperative ecchymosis, swelling and pain. Thus far, no decent study evaluated the efficacy of topical Arnica ointment in reducing ecchymosis or surgical outcome after upper blepharoplasty. We hypothesize that application of Arnica ointment postoperatively will reduce the development of ecchymosis and improve outcome.
The purpose of this registry is to observe longterm performance and safety of the JenaValve TAVI system, in routine medical and everyday conditions.
