Effect of neuronavigated repetitive Transcranial Magnetic Stimulation on pain, cognition and cortical excitability in fibromyalgia syndrome.

BACKGROUND: Fibromyalgia syndrome is a widespread chronic pain condition identified by body-wide pain, fatigue, cognitive fogginess, and sleep issues. In the past decade, repetitive transcranial magnetic stimulation has emerged as a potential management tool.. In the present study, we enquired whether repetitive transcranial magnetic stimulation could modify pain, corticomotor excitability, cognition, and sleep. METHODS: Study is a randomized, sham-controlled, double-blind, clinical trial; wherein after randomizing thirty-four fibromyalgia patients into active or sham therapy (n = 17 each), each participant received repetitive transcranial magnetic stimulation therapy. In active therapy was given at 1 Hz for 20 sessions were delivered on dorsolateral prefrontal cortex (1200 pulses, 150 pulses per train for 8 trains); while in sham therapy coil was placed at right angle to the scalp with same frequency. Functional magnetic resonance imaging was used to identify the therapeutic site. Pain intensity, corticomotor excitability, cognition, and sleep were examined before and after therapy. RESULTS: Baseline demographic and clinical parameters for both active and sham groups were comparable. In comparison to sham, active repetitive transcranial magnetic stimulation showed significant difference in pain intensity (P < 0.001, effect size = 0.29, large effect) after intervention. Other parameters of pain perception, cognition, and sleep quality also showed a significant improvement after the therapy in active therapy group only, as compared to sham. CONCLUSIONS: Findings suggest that repetitive transcranial magnetic stimulation intervention is effective in managing pain alongside cognition and sleep disturbances in patients of fibromyalgia. It may prove to be an important tool in relieving fibromyalgia-associated morbidity.

Correlating cognition and cortical excitability with pain in fibromyalgia: a case control study.

BACKGROUND: Fibromyalgia is a chronic pain disorder characterized by widespread musculoskeletal symptoms, primarily attributed to sensitization of somatosensory system carrying pain. Few reports have investigated the impact of fibromyalgia symptoms on cognition, corticomotor excitability, sleepiness, and the sleep quality - all of which can deteriorate the quality of life in fibromyalgia. However, the existing reports are underpowered and have conflicting directions of findings, limiting their generalizability. Therefore, the present study was designed to compare measures of cognition, corticomotor excitability, sleepiness, and sleep quality using standardized instruments in the recruited patients of fibromyalgia with pain-free controls. METHODS: Diagnosed cases of fibromyalgia were recruited from the Rheumatology department for the cross-sectional, case-control study. Cognition (Mini-Mental State Examination, Stroop color-word task), corticomotor excitability (Resting motor threshold, Motor evoked potential amplitude), daytime sleepiness (Epworth sleepiness scale), and sleep quality (Pittsburgh sleep quality index) were studied according to the standard procedure. RESULTS: Thirty-four patients of fibromyalgia and 30 pain-free controls were recruited for the study. Patients of fibromyalgia showed decreased cognitive scores (p = 0.05), lowered accuracy in Stroop color-word task (for color: 0.02, for word: 0.01), and prolonged reaction time (< 0.01, < 0.01). Excessive daytime sleepiness in patients were found (< 0.01) and worsened sleep quality (< 0.01) were found. Parameters of corticomotor excitability were comparable between patients of fibromyalgia and pain-free controls. CONCLUSIONS: Patients of fibromyalgia made more errors, had significantly increased reaction time for cognitive tasks, marked daytime sleepiness, and impaired quality of sleep. Future treatment strategies may include cognitive deficits and sleep disturbances as an integral part of fibromyalgia management.

Assessment of pain and structure after an intra-articular injection of adalimumab in osteoarthritis of the knee: A case report.

INTRODUCTION: Tumor necrosis factor alpha (TNF-α) mediated inflammation has been implicated, in knee osteoarthritis, despite being a predominantly degenerative condition. PATIENT CONCERNS: A 56-year old female, a case of left knee pain not responding to conventional conservative strategies. DIAGNOSIS: A diagnosis of primary osteoarthritis of the left knee, grade 3 osteoarthritis as per the Kellgren-Lawrence Scale was established. INTERVENTIONS: She was administered an intra-articular injection of 10 mg of Adalimumab, a commonly used anti-TNF agent. OUTCOMES: The patient was evaluated at baseline, 1 month, 3 months, and at 6 months. There was a marked improvement in pain intensity (visual analog scale) and quality of life, despite no objective change on the parameters seen on ultrasound of the knee. CONCLUSION: Injection of adalimumab via the intra-articular route into the knee joint in primary osteoarthritis yields promising results.

Effectiveness of Hatha Yoga Versus Conventional Therapeutic Exercises for Chronic Nonspecific Low-Back Pain.

Objective: To determine whether the effectiveness of Hatha yoga therapy is comparable to conventional therapeutic exercises (CTEs) for reducing back pain intensity and back-related dysfunction in patients with chronic nonspecific low-back pain (CNLBP). Design: The study was a prospective randomized comparative trial, divided into two phases: an initial 6-weekly supervised intervention period followed by a 6-week follow-up period. Settings: This study was conducted at Department of Physical Medicine and Rehabilitation and Centre for Integrative Medicine and Research of a tertiary care hospital. Subjects: Patients between 18 and 55 years of age with complaint of CNLBP persisting ≥12 weeks with pain rating ≥4 on a numerical rating scale (0-10). Intervention: A total of six standardized 35-min weekly Hatha yoga sessions (yoga group) and similarly 35-min weekly sessions of CTEs (CTE group), designed for people with CNLBP unaccustomed to structured yoga or CTE program. Participants were asked to practice on nonclass days at home. Outcome measures: The primary outcome measures were Defense and Veterans Pain Rating Scale (DVPRS) (0-10) and 24-point Roland Morris Disability Questionnaire (RDQ). Secondary outcomes were pain medication usage per week and a postintervention Perceived recovery (Likert seven-point scale) of back-related dysfunction. Outcomes were recorded at the baseline, 6-week follow-up, and 12-week follow-up. Results: Seventy subjects were randomized to either yoga (n = 35) or CTE group (n = 35). Data were analyzed using intention-to-treat, with last observation carried forward. Both yoga and the CTE group have shown significant improvement in back pain intensity and back-related dysfunction within both the groups at 6- and 12-week follow-ups compared to baseline. No statistically significant differences in the pain intensity (DVPRS; at 6 weeks: n = 35, difference of medians 1.0, 95% confidence interval [-5.3 to 3.0], p = 0.5; at 12 weeks: n = 35, 0.0 [-4.2 to 5.0], 0.7) and back-related dysfunction (RDQ; at 6 weeks: n = 35, 1.0 [-9.6 to 10.6], 0.4; at 12 weeks: n = 35, 0.0 [-8.8 to 10.6], 0.3) were noted between two groups. Improvements in pill consumption and perceived recovery were also comparable between the groups. Conclusion: Yoga provided similar improvement compared with CTEs, in patients with CNLBP.

The Zebrafish GenomeWiki: a crowdsourcing approach to connect the long tail for zebrafish gene annotation.

A large repertoire of gene-centric data has been generated in the field of zebrafish biology. Although the bulk of these data are available in the public domain, most of them are not readily accessible or available in nonstandard formats. One major challenge is to unify and integrate these widely scattered data sources. We tested the hypothesis that active community participation could be a viable option to address this challenge. We present here our approach to create standards for assimilation and sharing of information and a system of open standards for database intercommunication. We have attempted to address this challenge by creating a community-centric solution for zebrafish gene annotation. The Zebrafish GenomeWiki is a 'wiki'-based resource, which aims to provide an altruistic shared environment for collective annotation of the zebrafish genes. The Zebrafish GenomeWiki has features that enable users to comment, annotate, edit and rate this gene-centric information. The credits for contributions can be tracked through a transparent microattribution system. In contrast to other wikis, the Zebrafish GenomeWiki is a 'structured wiki' or rather a 'semantic wiki'. The Zebrafish GenomeWiki implements a semantically linked data structure, which in the future would be amenable to semantic search. Database URL: http://genome.igib.res.in/twiki.
