Filter by:Aim of the study Failed back surgery syndrome (FBSS) is a clinical entity consisting of chronic leg and /or back pain due to radicular nerve damage. The effectiveness of Spinal Cord Stimulation (SCS) in the pain management of patients with FBSS is proven. Patients mostly have dominant leg pain, however a significant percentage of FBSS patients has a more pronounced back pain and are commonly excluded from SCS as it is often inadequate in relieving both the back and leg pain components. Recently some reports showed the benefit of subcutaneous stimulation (SubQ) for low back pain in patients with FBSS. This has been confirmed by a feasibility study performed by our group. The aim of the randomized controlled study is to evaluate the effect of SubQ on low back pain in FBSS patients for whom SCS gives an inadequate back pain relief. Hypothesis We hypothesize that SubQ in addition to SCS in FBSS patients with leg and low back pain is more effective in treating low back pain (i.e. >50% pain reduction) than SCS alone.
The purpose of the long-terms study is to evaluate the safety, tolerability, and analgesic efficacy of EN3409 in subjects with moderate to severe chronic pain requiring continuous around-the-clock opioid analgesia for an extended period of time.
The purpose of this trial is to investigate the efficacy and safety of lidocaine 5% medicated plaster in localized chronic post-operative neuropathic pain in comparison to placebo plaster.
Neuropathic (nerve pain) following amputation of a limb is very common, affecting 60-80% of patients (Sherman et al, 1984). It can prolong their recovery making it difficult to fit protheses and mobilise. Current treatment options are limited and existing painkillers have significant side effects. Nevertheless there is some evidence that pre-emptive analgesia (pain relief provided prior to the surgery) has additional benefits after the surgery (Ypsilantis & Tang, 2010) Qutenza (topical capsaicin 8%)is a novel analgesic agent which is applied directly onto the skin. It works by desensitising to pain receptors in the skin (Nolano et al., 1999) and has been shown to be effective in reducing neuropathic pain in other conditions (Backonja et al., 2008) We propose to evaluate the use of Qutenza for pre-emptive analgesia in patients undergoing amputation of a limb. This is a small, pilot, randomised controlled study of 30 patients undergoing lower limb amputation who will have Qutenza or active control applied prior to surgery. They will be followed up for 12 weeks post-operatively with regular assessment of pain scores, quality of life and wound healing.
Arteriovenous fistulae are artificial connections between the artery and vein in the arm which allow needles to be inserted for haemodialysising patients wit kidney failure. Occasionally severe debilitating pain can arise from these fistulae for which no cause can be found. Such pain can be very difficult to treat. Many commonly used used painkillers are known to cause significant side effects in patients with renal failure (drowsiness, confusion etc. Qutenza (topical capsaicin 8%) is a new treatment made from chilli peppers which is applied to the skin as a patch and works directly at the nerve endings in the skin to prevent pain. It therefore should not have the systemic side effects of other drugs. It has been demonstrated to be beneficial in other painful conditions for example post-shingles pain and nerve pain from HIV. It has never been used for critical ischaemia before. We propose to investigate the efficacy of Qutenza in treating patients with end stage renal failure and chronic pain from their fistulae (AVF). We will recruit 20 patients with painful AVF and treat them with Qutenza. We will follow them up for 12 weeks and monitor the change in their pain scores.
Based on laboratory studies, donepezil will improve pain relief more than placebo in patients with chronic neuropathic pain who are currently taking gabapentin or pregabalin.
The primary objective of this study is to identify osteoarthritis (OA) structural changes, as assessed by MRI, that best correlate with the presence of neuropathic pain (NP) using the PainDETECT questionnaire (PainDETECT ≥ 13) on a population of patients with OA of the knee experiencing moderate to severe pain (VAS ≥ 40 mm).
Pain is one of the most common symptoms associated with cancer. The approach to pain management compresses routine pain assessments, utilizes both pharmacologic and nonpharmacologic interventions, and requires ongoing reevaluation of the patient. Cancer pain can be well controlled in the vast majority of patients if the algorithms of pain control are systematically applied, carefully monitored, and tailored to the needs of the individual patient.This study is aimed to assess the current pain managements in upper gastrointestinal cancer patients in Taiwan. The effects of neuropathic pain and depression on the enrolled patients would also be assessed.
An International, multicenter, epidemiological observational study investigating the prevalence of Transthyretin-Related Familial Amyloidotic Polyneuropathy (TTR-FAP) in participants with small fiber polyneuropathy of no obvious etiology.
Critical ischaemia is pain at rest as the result of poor blood flow and lack of oxygen being delivered to the tissues. It normally affects the hands and feet and can be very debilitating. It is particularly common and difficult to treat in patients with end stage renal failure Patients with renal failure are often high risk of any operative intervention which might help the pain. Often the only treatment options are painkillers. Unfortunately however, the commonly used painkillers, for example morphine, are known to cause worse side effects in patients with renal failure (drowsiness, confusion etc. Qutenza (topical capsaicin 8%) is a new treatment made from chilli peppers which is applied to the skin as a patch and works directly at the nerve endings in the skin to prevent pain. It therefore should not have the systemic side effects of other drugs. It has been demonstrated to be beneficial in other painful conditions for example post-shingles pain and nerve pain from HIV. It has never been used for critical ischaemia before. We propose to investigate the efficacy of Qutenza in treating patients with end stage renal failure and painful ischaemia. We will recruit 20 patients with painful ischaemia and treat them with Qutenza. We will follow them up for 12 weeks and monitor the change in their pain scores.
