Active clinical trials for "Recurrence"

As low back pain is often a recurrent and sometime persistent problem, research into prevention is important. Chiropractors have traditionally treated patients with maintenance care, which means that patients are seen on a regular basis to prevent recurrences or to stop a persistent problem getting worse. However, it is not known if this has the expected effect. This study will test the effectiveness of the maintenance care approach. Patients with recurrent or persistent low back pain will be treated in accordance with two different models. The first model is the maintenance care model, meaning that chiropractors will see the patient on a regular basis, regardless symptoms. The other model means that patients should be treated patients only when they themselves experience symptoms bad enough to seek care. After one year, it will be possible to see if there has been any difference between the groups in terms of pain, disability, quality of life and total number of treatments over the study period and to investigate if there is any difference in the cost-effectiveness between the two treatment models.Thus, the study hypothesis is that there is no difference between the two models regarding the number of days with pain. This study will be a multi-centre trial, and as part of the study, it will be necessary to formalize a network of research clinics all over Sweden in which participating chiropractors accept to perform complex data collection. This network will then have the expertise and potential to perform future clinical studies together with networks in other countries, allowing large clinical trials across countries.

The purpose of this study is to evaluate the efficacy of repetitive transcranial magnetic stimulation in the prevention of relapse of the symptoms of depression. Primary Outcome Measures:Time between subject randomization to treatment and the first occurrence of a relapse during the Relapse Prevention Period. Secondary Outcome Measures: Symptom change as measured by Hamilton Depression Rating Scale (HDRS); Illness severity change as measured by Clinical Global Impression of Severity for depression(CGI-S-DEP); Change in subject functioning using the Personal and Social Performance Scale.

This is a study of the drug tinidazole for women with recurrent bacterial vaginosis. Half of the participants will get the drug for 10 days, the other half will get the drug for 10 days and then twice a week for 12 weeks.

This purpose of this study is to determine the optimal frequency of maintenance intervention needed to prevent glycemic relapse.

RATIONALE: Stent placement may help reduce symptoms caused by the tumor. Photodynamic therapy uses a drug, such as porfimer sodium, that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. This may be an effective treatment for cholangiocarcinoma. It is not yet known whether stent placement and photodynamic therapy using porfimer sodium are more effective than stent placement alone in treating cholangiocarcinoma. PURPOSE: This randomized phase III trial is studying stent placement and photodynamic therapy using porfimer sodium to see how well they work compared to stent placement alone as palliative treatment in treating patients with stage III or stage IV cholangiocarcinoma that cannot be removed by surgery.

RATIONALE: Drugs used in chemotherapy, such as capecitabine, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving capecitabine after surgery may kill any remaining tumor cells. PURPOSE: This phase II trial is studying how well capecitabine works in treating patients who have undergone surgery for locally recurrent or persistenthead and neck cancer.

The purpose of this research study is to test a new treatment for prostate cancer. We have been exploring the use of cytokine (immune stimulating) gene therapy by directly injecting a virus which produces a cytokine called interleukin-12 (IL-12) into the prostate gland to control tumor growth. We propose to explore the use of adenovirus-mediated human interleukin-12 (Ad.hIL-12) in patients with recurrent non-metastatic prostate cancer following radiation therapy in a Phase I trial. Participants will be placed in rising dose groups with the primary endpoint of learning the maximum dose that can safely be given by injection directly into the prostate gland. Toxicity will be determined through physical examination, laboratory values, and blood levels of cytokines. Evidence of an immune response against prostate proteins will also be monitored. If the treatment works, the cancer will shrink or not grow. This will be monitored by prostate specific antigen (PSA) levels in the blood. However, we do not know if this treatment will be effective. If the PSA continues to rise after treatment, participants will be taken off study and offered other treatment. There is no compensation for participation in this research study. There will be no charge for the treatment with gene therapy or the monitoring associated with this research study. Monitoring will occur in a specially designated clinical research center.

This study will determine whether the addition of Cognitive Therapy (CT) to antidepressant medication (ADM) enhances treatment for depression. This study will also test whether the addition of CT to ADM will prevent recurrences of depression after therapy is over.

High-grade intraepithelial lesion/cervical intraepithelial neoplasia grade 2-3 is a premalignant cervical lesion caused by persistent high-risk human papillomavirus infection. Human papillomavirus test is a very sensitive risk marker of cervical cancer and it has been incorporated in the follow-up after high-grade intraepithelial lesion treatment. Papillomavirus test performed intraoperatively could be a beneficial approach to anticipate treatment failure, allow for early management and consequently a reduction in costs. The aim of this study is to evaluate if the IOP-HPV test has non-inferior diagnostic utility of HSIL/CIN2-3 recurrence at 24 months as the HPV test performed 6 months after treatment.
