NCT01307540
Study hypothesis: light therapy may prevent oral ulcers in bone marrow recipients. Methods: patients will be treated with either active light-emitting device or inactive light-emitting device. Daily treatment with light therapy will start at the beginning of the conditioning regimen and will last until day 21 post-transplant. Each daily treatment last about 5 minutes. Patients will be evaluated for oral mucositis and oral pain level on a weekly basis.
NCT01307189
This study was designed to test the following hypothesis: A) The acute and long-term (3 weeks) bronchodilator-induced changes in exercise tolerance and in the physiological response during the endurance shuttle walk will be greater with tiotropium compared to placebo in COPD patients. B) Three weeks of bronchodilation will be associated with increase activity of daily living as evaluated using the London Chest Activity Daily Living scale.
NCT00150085
New onset diabetes mellitus (NODM) post- transplantation decreases patient and graft survival. Some immunosuppressive agents are associated with a higher incidence of NODM. This study evaluates the safety and efficacy of converting patients with NODM from tacrolimus to cyclosporine micro-emulsion as a primary immunosuppressant for kidney and liver recipients.
NCT01298635
Primary angle closure glaucoma (PACG) is caused by contact between the iris and trabecular meshwork, which in turn obstructs outflow of the aqueous humor from the eye. This contact between iris and trabecular meshwork (TM) may gradually damage the function of the meshwork until it fails to keep pace with aqueous production, and the pressure rises, and at last the optic nerve is damaged, the vision may be lost in some severe cases. Therefore, ocular pressure reduction is the key to treat the disease and prevent blindness. Trabeculectomy is the most common conventional surgery performed for glaucoma. This allows fluid to flow out of the eye through this opening, resulting in lowered intraocular pressure(IOP) and the formation of a bleb or fluid bubble on the surface of the eye. Cataract surgery is common in the elderly. Cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract. Cataract extraction includes intracapsular cataract extraction, extra capsular cataract extraction \& phacoemulsification, and phacoemulsification is the preferred method. It has been reported that IOP reduction could occur in cataract patients with PACG after the cataract surgery. For some cases with PACG, such IOP reduction may be insufficient for neuronal protection, and many patients still require glaucoma medication and incisional surgery such as trabeculectomy to control IOP. In such cases, a combined cataract-glaucoma procedure (phacotrabeculectomy) is a reasonable option. In keeping with this concept, previous studies have shown that phacotrabeculectomy could effectively and simultaneously reduce IOP and improve vision in patients with a coexistence of PACG and vision-threatening cataract. However, phacotrabeculectomy may heighten inflammatory response, result in a higher frequency of postoperative complications such as hyphema and fibrin in the anterior chamber, endophthalmitis, and increased scarring of the filtering bleb. Thus, it is unclear whether phacotrabeculectomy is as effective and safe as trabeculectomy in lowering IOP for PACG patients. In the present study, the investigators compared the efficacy and safety of phacotrabeculectomy and trabeculectomy in patients with coexisting PACG and cataract.
