To examine the effect of ergocalciferol treatment on 25-hydroxyvitamin D and PTH levels in patients with CKD stage 3 and 4
The purpose of this small study was to investigate the safety and effectiveness of OROS hydromorphone HCI for the treatment of short-term, moderate to severe postoperative pain following total knee replacement surgery.
The Roux-En-Y gastric bypass procedure is the most commonly performed bariatric procedure in the United States. Despite initial weight loss, some patients experience weight regain that may be related to an increase in the size of the gastric pouch and/or stoma. A second surgical procedure to reduce the size of the pouch and/or stoma is typically associated with a higher risk of death or complications than the original gastric bypass procedure. This study will evaluate a less invasive, endolumenal alternative to pouch and stoma revision as a means of producing weight loss in patients who have regained weight following gastric bypass.
The purpose of this prospectively randomized multicentre study was to prove the efficacy and safety of mycophenolate mofetil (MMF) to preventing graft rejection and improvement of clear graft survival following high-risk keratoplasty. The patients of the MMF group receive MMF orally 2x1 g daily for 6 months. Endpoints were immune reaction free and clear graft survival and the occurence of side-effects.
Long term survival can now be achieved in 75% of cases of pediatric cancers. However, some types of tumors (ie CNS tumors) or advanced stages (metastatic sarcomas/neuroblastomas) cannot be cured by any treatment. Thus, evaluation of new drugs or combinations are strongly needed. The recommended doses have been defined in children for TMZ (200 mg/m2/d x 5 d) and TPT (1.5 mg/m2/d x 5 d). Some preclinical and clinical studies have shown activity of both drugs in some pediatric cancers. Nevertheless, the association of the two drugs has never been evaluated. The study aims to determine Maximum Tolerated Dose and dose limiting toxicities of each drug when associated and to assess efficacy of the combination.
This 2 arm study will evaluate the efficacy and safety of Tamiflu in the seasonal prophylaxis of influenza in immunocompromised patients (as represented by transplant recipients). Transplant recipients enrolled when influenza is circulating in the community will be randomized to receive Tamiflu syrup or capsules 30mg-75mg daily (depending on body weight) or placebo for 12 weeks. Influenza symptoms and safety data will be recorded throughout the study. The anticipated time on study treatment is <3 months, and the target sample size is 100-500 individuals.
This single arm study will determine the effects of complete anemia correction in anemic patients with end-stage renal disease currently receiving suboptimal doses of NeoRecormon. Patients on dialysis receiving NeoRecormon, and with a hemoglobin level <105g/L, will be treated with subcutaneous NeoRecormon at a dose determined by the investigator in order to reach (within 3 months) and maintain a hemoglobin level in the range of 120-135g/L. Heart function and quality of life will be measured before and after anemia correction. The anticipated time on study treatment is 3-12 months, and the target sample size is 100 individuals.
The specific aim of this study is to demonstrate that inserting a breathing tube using a standard laryngoscope with the patient fully anesthetized is a safe and effective means of securing the airway in a patient with cervical spine disk herniation or stenosis. The two groups compared are composed of those who are intubated with direct laryngoscopy and those who are intubated with a fiberoptic scope.
The objective of this study is to evaluate the effect of brimonidine tartrate ophthalmic solution 0.15% (Alphagan P) on pupil diameter under different luminance conditions.
The purpose of this study is to conduct a prospective assessment of small target contrast sensitivity and disability glare in refractive surgery. Study subjects will undergo the treatment of their choice (PRK or LASIK) and will be evaluated before and after treatment. Evaluations will include best corrected visual acuity, uncorrected visual acuity, psychometric questionnaire, pupil size, biomicroscopic examination, manifest refraction, wavefront measurements, low contrast acuity, and contrast sensitivity at normal and at low luminance with and without disability glare.
