NCT ID: NCT01015482 Recruiting - Hyperalgesia Clinical Trials

The Effect of High-dose Remifentanil on Established Sunburn-induced Hyperalgesia in Human Volunteers (HighDose RemiSun)

Start date: November 2009
Phase: Phase 4
Study type: Interventional

Treatment of chronic pain is a major clinical challenge since chronic pain is frequent and leads to deterioration of quality of life. An injury or wound can lead to long term changes in the nervous system that make the skin more sensitive at and near the injury; this is termed hyperalgesia and occurs through long term depotentiation (LTP), i.e., a change in the synaptic interaction between neurons. Opioids are the gold standard for the symptomatic therapy of moderate to severe pain. Now, in animal studies the investigators have discovered previously unrecognized effects of opioids. UV-B irradaition of the skin of the thigh is an established model of priamary and secondary hyperalgeisa in humans. The investigators want to test the influence of remifentanil, an ultra-short acting opioid, on hyperalgesia observed after UV-B irradiation in human volunteers in a double blind cross-over prospective active placebo controlled clinical trial, at a dose corresponding to 0.7 µg kg-1 min-1.

NCT ID: NCT01015469 Recruiting - Clinical trials for Morbid Obesity Requiring Bariatric Surgery

Banded Versus Conventional Laparoscopic Roux-en-Y (GABY)

GABY
Start date: February 2009
Phase: Phase 4
Study type: Interventional

Banded Versus Conventional Laparoscopic Roux-en-Y Gastric Bypass (GABY). The aim of this novel study is to evaluate, if an additional restrictive silastic ring can avoid dilation of the gastro-entero anastomosis and adjacent small bowel with consecutive better postoperative weight loss and significantly improved long-term weight maintenance. The study will not investigate the GaBP-Ring as medical product but the effect of the GaBP-Ring on weight loss in comparison to gastric bypass alone.

NCT ID: NCT00973336 Recruiting - Clinical trials for Primary Hyperparathyroidism

Primary Hyperparathyroidism: Does a Systematic Treatment Improve the Calcium and Bone Metabolism After Surgery?

Start date: September 2009
Phase: Phase 2
Study type: Interventional

Primary Hyperparathyroidism (pHPT) increases bone turnover and resorption and thus calcium efflux out of bone. After successful surgical treatment of pHPT, bone takes up calcium again which may result in secondary hyperparathyroidism or even "hungry bone syndrome". Until today there are no studies about this problem helping to develop recommendations or guidelines how to prevent these symptoms. Study hypothesis: Calcium and vitamin D intake after surgery for PHPT protects the bone by keeping PTH in the normal range (less secondary, reactive hyperparathyroidism), prevents hungry bone- syndrome and improve bone-turnover markers (osteoporosis protection).

NCT ID: NCT00926861 Recruiting - Clinical trials for Dry Age-related Macular Degeneration

Posterior Macular Adhesion: A Potential Risk Factor for Non-exudative Age Related Macular Degeneration (AMD) to Develop Exudative AMD

PAM
Start date: July 2009
Phase: N/A
Study type: Observational

Choroidal neovascularisation in age related macular degeneration is one of the major causes of legal blindness in the western world existing in two major occurences, the dry and the wet form.The etiology of age related macular degeneration is yet unknown. Genetic factors, oxidative stress, Ischaemia, and aging of the retinal pigment epithelium are discussed as etiologic factors. The risk of rapid vision loss is much higher in wet AMD, a dry form may transform to a wet form. From a prior study the investigators know that the posterior hyaloid is significantly more frequent attached in wet AMD. This study is conducted to examine whether the attached posterior hyaloid is a risk factor to develop wet AMD in dry AMD cases.

NCT ID: NCT00926081 Recruiting - Clinical trials for Peripheral Artery Disease

Exercise Training Versus Best Medical Treatment Only in Peripheral Artery Disease

Start date: November 2007
Phase: N/A
Study type: Interventional

The aim of the investigators' study is to analyze the value of supervised exercise training combined with medical therapy versus best medical treatment only with respect to quality of life. Furthermore, the investigators aim to evaluate the effect of supervised exercise training on microcirculation, peripheral endothelial progenitor cells as well as on future major cardiovascular adverse events.

NCT ID: NCT00924274 Recruiting - Clinical trials for Familial Hypercholesterolemia

Effect of Rapeseed Oil and Sunflower Oil

Start date: March 2008
Phase: N/A
Study type: Interventional

Familial hypercholesterolemia (FH), an inherited disorder of lipoprotein metabolism, is a risk for early cardiovascular disease (CVD). This autosomal dominant disease is characterized by markedly elevated plasma concentrations of low density lipoprotein (LDL) and total cholesterol (TC). The purpose of this study is to compare the effect of a diet low in saturated fats but enriched either with rapeseed oil (RO) or sunflower oil (SO) in children and adolescents with FH on serum lipoproteins.

NCT ID: NCT00921037 Recruiting - Clinical trials for Cutaneous Neurofibromas

First Clinical Study of Erbium - Yttrium Aluminium Garnet (YAG) Laser Vaporization of Cutaneous Neurofibromas

Start date: April 2006
Phase: Phase 2/Phase 3
Study type: Interventional

The purpose of this study is to determine whether multiple cutaneous neurofibromas in patients with neurofibromatosis type 1 can be removed with an erbium-YAG-laser.

NCT ID: NCT00903110 Recruiting - IGF1 Deficiency Clinical Trials

Global Patient Registry to Monitor Long-term Safety and Effectiveness of Increlex® in Children and Adolescents With Severe Primary Insulin-like Growth Factor-1 Deficiency (SPIGFD).

Start date: December 9, 2008
Phase:
Study type: Observational [Patient Registry]

The Increlex® Global Registry is a descriptive, multicenter, observational, prospective, open-ended, non interventional, post-authorisation surveillance registry. The main purpose of this global registry is to collect, analyse and report safety data during and up to at least 5 years after the end of treatment in children and adolescents receiving Increlex® therapy for SPIGFD according to the locally approved product information.

NCT ID: NCT00898118 Recruiting - Leukemia Clinical Trials

Studying Blood Samples in Young Patients With Cytopenia After a Donor Stem Cell Transplant

Start date: April 2007
Phase: N/A
Study type: Observational

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at blood samples in young patients with cytopenia after undergoing a donor stem cell transplant.

NCT ID: NCT00892359 Recruiting - Infection Clinical Trials

Anidulafungin During Continuous Venovenous Hemofiltration (CVVHF)

Start date: April 2009
Phase: Phase 2
Study type: Interventional

The purpose of this trial is to study the pharmacokinetics of anidulafungin during continuous venovenous hemofiltration. Background: Anidulafungin is a cyclic lipopeptide antifungal agent of the echinocandin class. Members of this class of antifungal agents are known to inhibit the synthesis of glucan polymers in fungal cell walls. The spectrum of activity of anidulafungin includes Candida (all species, including strains resistant to fluconazole), Aspergillus, and Pneumocystis. In intensive care patients continuous venovenous haemodiafiltration (CVVHF) is a well-established extracorporal renal replacement therapy with a high clearance rate. Pharmacokinetic studies of antifungal agents in critically ill patients treated with CVVHF are rare. No data about anidulafungin in CVVHF are available although intensive care patients are perfect candidates for anidulafungin treatment due to their high risk profile for systemic fungal infections. Study objective: The study is conducted to investigate the pharmacokinetics of anidulafungin during CVVHF in critically ill patients. Study design: open, 1 arm Study population: 10 critically ill adult patients administered to the ICU with acute renal failure and suspected or proven fungal infection. Treatment/Dosage/Route: On the first day 200 mg of anidulafungin will be administered intravenously over 3 hours (loading dose). The following days 100 mg of anidulafungin will be administered intravenously over 1.5 hours. Main outcome variables: The following pharmacokinetic parameters will be determined: area under the curve (AUC), half-live (t1/2), maximum plasma concentration (Cmax) and elimination fraction. Methods: High pressure liquid chromatography (HPLC) will be used to determine anidulafungin concentrations.
