Clinical TrialSacral nerve modulation in the treatment of chronic pelvic pain.
Chronic pelvic pain is a common condition that significantly compromises the quality of life of affected patients. Unfortunately, despite treatment procedures, the results are often ineffective and symptoms persist for years. For these reasons, the search for less aggressive treatment options with fewer negative consequences leading to minimally invasive techniques was conducted. ⋯ Sacral neuromodulation proved to be effective in the treatment of some patients affected by chronic pelvic pain, and the effect persists over time. A positive screening phase and a positive response to gabapentin or pregabalin showed to be predictors of a successful response. Multiple localizations of pelvic pain and pain occurred after stapler surgery seem to be negative factors for the success of the treatment.

Although research suggests there is considerable overlap among chronic pain, fatigue, and sleep disturbances, no research to date has concurrently examined their interrelationships. This study estimates the co-occurrence of these three conditions in terms of prevalence and associated factors in the general adult population. ⋯ This study has shown that the co-occurrence of chronic pain, fatigue, and sleep disturbances was common in the general adult population. Multiple symptoms are comorbid of psychological distress.

ReviewThe use of functional neuroimaging to evaluate psychological and other non-pharmacological treatments for clinical pain.
A large number of studies have provided evidence for the efficacy of psychological and other non-pharmacological interventions in the treatment of chronic pain. While these methods are increasingly used to treat pain, remarkably few studies focused on the exploration of their neural correlates. The aim of this article was to review the findings from neuroimaging studies that evaluated the neural response to distraction-based techniques, cognitive behavioral therapy (CBT), clinical hypnosis, mental imagery, physical therapy/exercise, biofeedback, and mirror therapy. ⋯ There was also evidence for decreased pain-related activations in afferent pain regions and limbic structures. If future studies will address the technical and methodological challenges of today's experiments, neuroimaging might have the potential of segregating the neural mechanisms of different treatment interventions and elucidate predictive and mediating factors for successful treatment outcomes. Evaluations of treatment-related brain changes (functional and structural) might also allow for sub-grouping of patients and help to develop individualized treatments.

ReviewImaging central neurochemical alterations in chronic pain with proton magnetic resonance spectroscopy.
Proton magnetic resonance spectroscopy has been used extensively in the study of various neurobiological disorders: depression, schizophrenia, autism, etc. But its application to chronic pain is relatively new. Not many studies in chronic pain have used (1)H-MRS. ⋯ The combination of (1)H-MRS imaging with pharmacologic interventions holds significant promise as a direct one-to-one matching of disease pathology with drug mechanism of action can be made. As such (1)H-MRS may be useful in discovery of novel compounds for chronic pain. Research in these areas may lead to improved diagnosis and treatment of these complex patients.
