Active clinical trials for "Chronic Pain"

There are quite a few qualitative studies done to find out patients experience of chronic pain. There are no studies on what the patients feel and what thoughts and feelings arise in the patients that are exposed to interventional pain management. This study aims to illuminate how it is to live through an interventional pain management program.

The purpose of this study is to assess the frequency of Fabry disease in children with chronic abdominal pain or chronic pain in the extremities

Does chest drains contribute to the post thoracotomy pain syndrome

This is a retrospective, observational study which will utilise the Edinburgh Cancer Research Centre's Tissue Bank to provide samples for IENFD testing in those who have undergone mastectomy surgery for breast cancer. The investigators shall identify all those patients in the Tissue Bank database who have undergone mastectomy surgery for breast cancer. The investigators shall consult the patient's electronic health record, and general practitioner if required, to ascertain whether the patient has died, been diagnosed with cognitive impairment or a psychotic disorder, or receiving ongoing oncological treatment which would exclude them from the study. The investigators shall also exclude all those patients who received surgery within the last year as we intend to elucidate the presence of pain in the immediate post-operartive period up to 12 months post-operatively. Having identified these patients the investigators shall contact them via post with a pack containing an information document, a consent form and questionnaires. As this is an observational study we shall contact all of the identified patients who meet the inclusion criteria with the aim of recruiting as many as possible. The investigators would anticipate a high response rate as has been the experience with previous questionnaire studies of breast cancer patients. Once a signed consent form has been returned the patient's tissue sample would undergo IENFD testing. Their questionnaire responses will allow participants to be split into two groups based upon whether they experience CPSP or not. Blinding of this grouping will take place so that those undertaking the IENFD testing are unaware of the patient's questionnaire responses. Statistical analysis of the two group's IEFD results and questionnaire responses will then be undertaken with the null hypothesis that the pre-operative IENFD at the site of surgery does not predict or correlate with CPSP.

This is an investigation on the frequency of chronic pain after thoracotomy for lung cancer. Factors relating to the development of chronic pain are investigated. Questionnaire survey.

The purpose of this study is to describe the demographic, medical, and psychological/behavioral characteristics of children and adolescent patients admitted to the Cleveland Clinic Children's Hospital's Pain Rehabilitation Program. The data will also be used to evaluate the clinical outcomes of patients admitted to the program as well as to examine the impact of various background factors on clinical outcomes.
