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.
Androgen deprivation therapy (ADT) is widely used as standard therapy in the treatment of locally advanced and metastatic prostate cancer. Hot flushes and night sweats are one of the main side-effects of ADT. There are no successful and well-tolerable treatment options available. A possible treatment for hot flushes is stellate-ganglion block (SGB), used as a means of interrupting parts of the sympathetic nervous system involved in temperature regulation. Objective of this study: To assess the short-term efficacy of stellate ganglion block on hot flush reduction versus sham procedure
Rationale: Vitiligo is a common skin disorder that can impair a patient's quality of life. Many depigmented lesions in vitiligo patients remain therapy resistant for medical treatment. Therefore new therapeutic options in these patients are necessary. Currently, dermabrasion by conventional or fractional laser therapy in combination with NB-UVB therapy and steroids appears to be effective in therapy resistant areas. However, little literature on this combination is available. Objectives: To assess the efficacy and patient safety of (1)fractional CO2-laser treatment in combination with NB- UVB,(2) fractional CO2-laser treatment in combination with NB- UVB and topical corticosteroids versus NB-UVB treatment alone(3) Study design: Prospective observer blinded randomised intra-patient controlled study. Study population: 23 patients ≥ 18 years with non segmental vitiligo who receive NB-UVB treatment at the Netherlands Institute for Pigment Disorders (SNIP) at the Academic Medical Centre University of Amsterdam. We will include patients with 3 depigmented lesions that are resistant to NB- UVB treatment after 3 to 6 months. Methods: Three NB-UVB resistant depigmented regions on the trunk or extremities will be randomly allocated to;(1) NB-UVB treatment in combination with fractional CO2 laser abrasion, or (2) NB-UVB treatment in combination with fractional CO2 laser abrasion and topical steroids, or (3) NB-UVB treatment alone. NB-UVB treatment and topical steroids will be given according to the standard treatment protocol of the SNIP and continued for at least 6 months. Two and 6 months after the laser treatment, the percentage of repigmentation of the lesions will be assessed.
The aim of the TINN2 study is to evaluate the efficacy of azithromycin in prevention of bronchopulmonary dysplasia in preterm neonates.
The study was designed to establish the safety of the Bayston Antimicrobial PD catheter that is impregnated with a "cocktail" of three well known anti-microbials
Advanced epithelial ovarian cancer has high morbidity and mortality. Patients presenting with advanced stage ovarian cancer often have cancer spread to regional lymph nodes. Imaging strategies to depict involved lymph nodes are currently not successful. The purpose of this study is to evaluate if magnetic resonance imaging (MRI) with gadofosveset trisodium contrast enhancement (GDF-MRI) and diffusion weighted imaging (DW-MRI) is able to identify involved lymph nodes in a preoperative setting. This could guide the surgeon during surgery to dissect lymph nodes which could lead to an optimal diagnosis/staging with the lowest possible morbidity. We want to determine the optimal imaging settings and feasibility of MRI for the detection of pathological lymph nodes in women with advanced (FIGO stage IIB-IV) ovarian cancer undergoing primary debulking surgery and compare this to conventional imaging with computer tomography (CT).
Despite improvements in therapy, head and neck carcinomas still have a poor prognosis with a 5-year survival of ~ 50%. Malignancies of the head and neck area are (almost) always preceded by precursor lesions. Treatment of these premalignant mucosal abnormalities is generally limited and not very inconvenient for the patient. If this precursor lesion remain untreated, it may develop into a malignancy of the head and neck. Extensive treatment will be necessary. This means loss of function of the mouth, eg chewing, speaking and swallowing. The hypothesis is that chromosomal instability (CIN) detected by fluorescence is situ hybridization (FISH) is a reliable indicator for progression to malignancy. By intensifying the follow up and treatment in premalignant CIN lesions, the incidence of progression to invasive carcinoma is expected to be significantly reduced. If this hypothesis is justified, there will be a place for CIN detection as a risk indicator in the diagnostic work up of premalignant lesions in the head and neck. The investigators second hypothesis is that loss of heterozygosity (LOH) detected bij DNA markers is a reliable indicator for progression to malignancy. By intensifying the outpatient clinic follow up and treatment in premalignant lesions, the incidence of progression to invasive carcinoma is expected to be significantly reduced. If this hypothesis is justified, there will be a place for CIN and LOH detection as a risk indicator in the diagnostic work up of premalignant lesions in the head and neck.
This is a Phase I multicenter, open-label, dose-escalation study of DTP348. DTP 348 is an oral dual drug with two mechanisms of action: 1. carbonic anhydrase IX inhibitor which acidifies the intracellular pH through the sulfamide components 2. radio sensitizer of hypoxic cells through its 5-nitroimidazole moiety The study will be conducted in 2 parts. The phase I trials will be on the standard 3+3 design first as single agent then combined with radiotherapy: 1. A single agent dose-escalation phase in patients with solid tumours. 2. A dose-escalation phase in patients with HNSCC in combination with radiotherapy The main objective is to determine the recommended phase II dose of DTP348 in combination with radiotherapy
The objective of this study is to obtain the absolute bioavailability of voriconazole in critically ill ICU patients, because pharmacokinetics can be different in critically ill patients due to alterations in function of various organs and body systems compared with healthy volunteers.
In endotracheal intubation, it is essential that the trachea is intubated and not the esophagus. In suboptimal situations (outside an operating theatre), malpositioning of the endotracheal tube occurs frequently and is often fatal. The diagnostic tools that are available in the operating theatre are not appropriate for out-of-hospital situations because of several reasons. Moreover, these methods mostly take some time to provide the desired information and don't have optimal specificity and sensitivity. In order to allow fast diagnosis of this potentially fatal complication, we have developed a fully-automatic detection device to diagnose endotracheal tube malpositioning within 2 seconds. A high sensitivity/specificity of the algorithm for waveform-analysis was demonstrated in healthy patients and patients with pulmonary diseases (decreased pulmonary compliance). A new stand-alone device with integrated sensors and microprocessor was developed that gives immediate diagnosis, and stores data for subsequent research purpose. This device will be evaluated in perioperative situations to demonstrate the high sensitivity and specificity in patients in a clinical setting.
In case of severe ankle arthritis, the two common surgical treatments are tibiotalar arthrodesis and total ankle arthroplasty. Few studies have compared these treatments and it remains difficult to determine which operation is the better solution for end stage ankle arthritis. The purpose of the present study is to analyze patient's outcome after each type of ankle surgery and to describe the decision making process.
