NCT ID: NCT01701245 Recruiting - Clinical trials for Chronic Cluster Headache

Prevention and Acute Treatment of Chronic Cluster Headache Compared to Standard of Care

Start date: October 2012
Phase: Phase 2
Study type: Interventional

Subjects enrolled into this 10 week study will for the first two weeks document the number of cluster headaches and the means of treating (medication) of these attacks. Subjects will then be randomized to into either two groups. The first group is continuing with standard of care and the second group is treatment with the investigational device (GammaCore) for a period of 4 weeks. After this 4 week period, all subjects will treat with the GammaCore for another 4 week period. It is hypothesized the the treatment group will have a reduction in mean cluster headaches per week by 50% compared to the standard of care group.

NCT ID: NCT01700699 Recruiting - Clinical trials for Differentiated Thyroid Cancer

Impact of BRAFV600E Intratumor Heterogeneity in Thyroid Cancer Treated With Tyrosine Kinase Inhibitors

Start date: October 2012
Phase: N/A
Study type: Observational

- Background: BRAFV600E is the most frequent oncogene in differentiated thyroid cancer (DTC) occurring in about 50% of cases. Clinical trials with tyrosine kinase inhibitors (TKI) with specific activity against BRAF in metastatic radioiodine-resistant DTC (MRR-DTC) are ongoing. Very recently it has been demonstrated that DTC often consists of a mixture of tumor cells with wild-type and mutant BRAF. The subclonal occurrence of BRAFV600E in MRR-DTC could disable the therapy with BRAF targeted TKI and be responsible of the frequent defeats of this treatment. A therapeutic strategy based upon BRAF inhibitors in tumors bearing subclonal BRAFV600E could be initially successful hitting the tumor cells expressing the oncogene, and after the initial tumor growth arrest and/or shrinkage, the oncogene negative cells insensitive or less sensitive to the treatment, could restart the growth of the tumor causing the progression of the disease and the escape from the clinical response. - Aims: To determine the impact of subclonal BRAFV600E on the efficacy of BRAF inhibitors in the treatment of MRR-DTC. - Study design: Primary tumor tissues will be analyzed for the presence of BRAFV600E by pyrosequencing or other quantitative assay. If available, synchronous metastases and post-therapy metachronous metastases will be analyzed as well. The clinical response will be determined according to RECIST, and the association with the percentage of BRAFV600E alleles will be evaluated. Attention will be paid to the possible difference of BRAFwild-type/BRAFV600E ratio between primary tumors and synchronous metastases, primary tumors and post-therapy metachronous metastases, and between responsive and resistant synchronous tumor lesions.

NCT ID: NCT01699516 Recruiting - Clinical trials for Neutropenic Enterocolitis

Non-invasive Contrast Enhanced Ultrasound Sonography in Intestinal Acute Graft-vs-Host Disease

Start date: January 2008
Phase: N/A
Study type: Observational

Intestinal acute graft-vs-host disease (GVHD) is a life-threatening complication after allogeneic hematopoietic cell transplantation. Non-invasive diagnostic procedures are still lacking and diagnosis is difficult. We hypothesized that contrast-enhanced ultrasound sonography (CEUS) could detect microcirculation changes of the bowel walls during intestinal GVHD and help to detect and monitor treatment response. We employed CEUS to prospectively evaluate intestinal GVHD in 83 consecutive transplant patients between 2008 and 2011. Fourteen /83 patients with biopsy-proven intestinal GVHD were selected as study group. Fourteen patients with biopsy-proven stomach GVHD without intestinal symptoms (N=16), normal volunteers (N=6) and patients with neutropenic enterocolitis (N=4), were chosen as control group. All patients were evaluated with both standard transabdominal ultrasonography (US) and CEUS at the onset of intestinal symptoms, during clinical follow up and at flare of symptoms. Standard US revealed non-specific bowel wall thickening, and simultaneous involvement of multiple intestinal segments in 9/14 patients. CEUS showed three distinct patterns of microcirculation changes that correlated with GVHD activity. These findings were not observed in the control group. Moreover, CEUS findings correlated with treatment response and predicted flare of intestinal symptoms. CEUS is a non-invasive, easily reproducible bed-side tool to detect and monitor intestinal GVHD.

NCT ID: NCT01694459 Recruiting - Stable Angina Clinical Trials

DEDICA (Dose of HEparin During Coronary Angioplasty) Trial

DEDICA
Start date: January 2010
Phase: Phase 4
Study type: Interventional

International guidelines support the use of a full-dose heparin (anticoagulants) during coronary intervention. However, a lower dose of heparin may be adequate, thanks to advances in angioplasty techniques and the widespread use of pretreatment with two antiplatelet agents. Thus the investigators designed a study comparing safety and efficacy of standard dose heparin (100 UI/Kg) versus low-dose (50 UI/Kg) in patients undergoing coronary angioplasty who are on aspirin and clopidogrel at the time of the procedure.

NCT ID: NCT01691573 Recruiting - Cardiac Arrhythmias Clinical Trials

European Pediatric Catheter Ablation Registry

EUROPA
Start date: July 2012
Phase: N/A
Study type: Observational

The main objective of the European Pediatric Catheter Ablation Registry is to collect data on ablation procedures in the European pediatric population in order to improve the management of this subset of patients.

NCT ID: NCT01691222 Recruiting - Heart Failure Clinical Trials

Tracheostomy in ICU With a Double Lumen Endotracheal Tube

Start date: July 2012
Phase: N/A
Study type: Interventional

Percutaneous tracheostomy in Intensive care unit (ICU) is performed with the use of flexible fiberoptic bronchoscope inside the conventional single lumen endotracheal tube owned by the patients. This situation may lead to many disadvantages for ventilation and airway protection of critically ill patients during the procedures. The use of double lumen endotracheal tube dedicated to the percutaneous tracheostomies may: 1. improve the ventilation of patients during the procedure, 2. protect the posterior tracheal wall from damage related to the different step of tracheostomies, 3. protect the lungs from blood and secretions coming down from the chosen site of tracheostomy. So the aim of this study is to evaluate the oxygenation, gas exchange, ventilation and complications of percutaneous tracheostomies performed in ICU with a dedicated double lumen endotracheal tube.

NCT ID: NCT01686659 Recruiting - Surgery Clinical Trials

Noninvasive and Continuous Hemoglobin Monitoring for Surgical Blood Management

NACHO
Start date: September 2012
Phase: N/A
Study type: Interventional

This is a multi-center cluster-randomized trial with the following Specific Aims: - To evaluate if continuous noninvasive hemoglobin monitoring will reduce the RBC transfusions in patients undergoing surgeries associated with a significant risk of bleeding. - To evaluate if patients monitored with continuous noninvasive hemoglobin experience less frequent complications and shorter hospital stay compared with patients who are not being monitored with continuous noninvasive hemoglobin. Accordingly, the study hypotheses are defined as follows: - The primary null hypothesis is that continuous noninvasive hemoglobin monitoring will not reduce the RBC transfusions in patients undergoing surgeries associated with a significant risk of bleeding. - The secondary hypothesis is that in patients monitored with continuous noninvasive hemoglobin, there will be earlier warning of critical drops in hemoglobin, and thus, there will be less frequent complications compared with patients who are not being monitored with continuous noninvasive hemoglobin.

NCT ID: NCT01671631 Recruiting - Clinical trials for Functional Evaluation of Non Culprit Lesions in ACS Patients

The Diastolic Pressure Gradient for Patients With Acute Coronary Syndrome: Evaluation of Non Culprit Lesions

FORECAST
Start date: n/a
Phase: N/A
Study type: Observational

The assessment of non-culprit stenoses is an important issue in ACS. Adenosine administration is currently required for functional evaluation of stenosis severity using the fractional flow reserve (FFR). An alternative adenosine-independent index of coronary stenosis, the instantaneous wave-free ratio (iFR), was recently introduced. Aim of the present study will be to evaluate the trans-stenotic instantaneous wave-free pressure gradient (iFG), the instantaneous wave-free ratio (iFR) and the fractional flow reserve (FFR) in ACS patients.
