Active clinical trials for "Necrosis"

Bevacizumab may have a better effect on brain necrosis caused by radiotherapy.This randomized trial aims to investigate whether bevacizumab may alleviate radiation-induced brain necrosis in patients with nasopharyngeal carcinoma. The effect will be compared with outcomes in patients receiving steroid therapy.

the object of this study is to evaluate clinically and radiographically the effect of using Biodentine and Mineral Trioxide Aggregate as coronal plug materials in revascularization of non-vital immature teeth

This trial is to compare clinical outcomes between patients undergoing immediate endoscopic necrosectomy compared to step-up endoscopic interventions in patients undergoing endoscopic therapy for infected necrotizing pancreatitis.

Patients enrolled in NIH protocol 95-I-0133 at the Clinical Center may participate in an extension phase of this study in which the drug prednisone will be eliminated from the treatment regimen. Prednisone is associated with avascular necrosis, a condition that has been found in a number of patients in this study. Also, certain patients in this protocol may receive future interleukin-2 treatment cycles at home. Home administration of IL-2 injections involves less frequent data and safety monitoring and no medical evaluations at the Clinical Center except at the beginning of each cycle. To be eligible for home administration of IL-2, patients must: Be enrolled in a current NIAID protocol for IL-2 therapy and have received at least 1 year of treatment on the protocol, with at least two well-tolerated outpatient cycles at a stable dose. Have a history of tolerable side effects while receiving IL-2 without frequent medical interventions, intravenous fluid replacement or dose reductions. Not have had any significant clinical or laboratory abnormalities during days 0 to 5 of the last two outpatient cycles. Have a strong relationship with a private physician or health-care provider who has been involved in the patient's care and is willing to help supervise the patient's care during each home IL-2 cycle. Live in a home with easy telephone access and have proved reliable in responding to telephone calls from clinic staff. Give the clinic staff contact information for a close friend or relative who will agree to serve as a caregiver during each home cycle, providing the patient non-medical assistance and checking on his or her condition daily. Have reasonable access to emergency medical services and a nearby medical facility. Have proved reliable and consistent in using sterile technique, reconstituting IL-2 vials and administering subcutaneous IL-2 injections. Be receiving outpatient IL-2 injections cycles at least once every 6 months as part of their normal protocol participation. Have access to a home weight scale and be able to weigh themselves each day for safety monitoring. Participants will receive IL-2 cycles on the same schedule they followed in their original protocol participation. They will be seen at the Clinical Center at regularly scheduled follow-up visits between cycles and for a medical evaluation and blood drawing before the start of each cycle to determine the safety of administering the cycle. During the home cycle, the patient's case manager or other team member will place monitoring telephone calls on days 2 and 4 of the cycle and again a week later. The timing and number of these calls may change depending on the findings of ongoing assessments of their usefulness. Patients will be required to notify the study team promptly of any complications or other problems that develop with therapy.

The purpose of this study is to determine if TNFR:Fc (a molecule that attaches to TNF) can lower the amount of IL-6 in HIV-positive patients. This study will also examine the effect of TNFR:Fc on TNF-alpha. IL-6 and TNF-alpha are 2 substances produced by the immune system that may increase the rate of HIV replication. IL-6 and TNF-alpha are produced naturally by the body. High levels of TNF-alpha lead to increased IL-6 production and increased HIV replication, therefore helping the virus infect the body. HIV-positive patients who receive IL-2 (interleukin-2, a protein that helps the immune system fight infection) tend to have higher levels of IL-6 and TNF-alpha than patients not receiving IL-2. These increased levels may contribute to some of the flu-like symptoms related to IL-2 administration. TNFR:Fc can neutralize TNF-alpha to decrease the action of TNF-alpha and, in turn, decrease the amount of IL-6 in the body. TNFR:Fc may, therefore, have a role in the treatment of HIV disease or in relieving some of the symptoms related to IL-2 administration.

The Division of Rheumatology at University of California San Francisco is conducting a research study on the treatment of ankylosing spondylitis (AS) with a new therapy currently used for people with other forms of arthritis. The drug, called Enbrel (or etanercept), is a protein that is given twice weekly by injection underneath the skin. It blocks the action of tumor necrosis factor-alpha (TNF-alpha), a substance that may be involved in AS, rheumatoid arthritis, and other inflammatory conditions. We will randomly assign patients to receive either the drug or a placebo (inactive treatment) for 4 months. The results we will monitor include morning stiffness, spinal mobility, activities of daily life, and safety of the drug.

The goal of the Shoulder iD™ Primary Reversed Glenoid Outcomes Clinical Study is to collect safety and performance data on the commercially available Shoulder iD™ Primary Reversed Glenoid device. The study will learn about standard device use in adult patients who have a functional deltoid muscle and massive and non-repairable rotator cuff tear. The main questions it aims to answer are: What is the average improvement in patient-reported shoulder function after 2 years when compared to before the surgery, and What is the rate of surgical revisions needed over a 10 year period Patients will be asked to will be asked to regularly attend their check-up visits with their surgeon (including having x-rays or CT images taken to check their shoulder and implant), to complete questionnaires to report how their shoulder is doing, and to tell their surgeon when they notice any changes.

Evaluation of the role of TRAIL and MCP-2 in differentiation between epileptic seizure and psychogenic non-epileptic seizure. Possible role to predict the prognosis of patients with epileptic seizure.

In this clinical trial, the researchers will investigate the effect of single-file reciprocating file system (Reciproc) versus multi-file rotational file systems (ProTaper Next) on the postoperative pain in adult patients who have necrotic pulp and apical periodontitis. The participants will be assigned by chance to separate groups that compare 2 different treatments, reciprocating single-file system (Reciproc) and rotational multi-file system (ProTaper Next).

The research design is a randomized prospective clinical study comparing the incidence of Walled Off Necrosis (WON) in patients with acute necrotizing pancreatitis.
