  • Nociplastic pain by the "International Association for the Study of Pain" is defined as pain that arises from altered nociception despite no clear evidence of nociceptive or neuropathic pain. Augmented central nervous system pain and sensory processing with altered pain modulation are suggested to be the mechanism of nociplastic pain. Clinical criteria for possible nociplastic pain affecting somatic structures include chronic regional pain and evoked pain hypersensitivity including allodynia with after-sensation. In addition to possible nociplastic pain, clinical criteria for probable nociplastic pain are pain hypersensitivity in the region of pain to non-noxious stimuli and presence of comorbidity such as generalized symptoms with sleep disturbance, fatigue, or cognitive problems with hypersensitivity of special senses. Criteria for definitive nociplastic pain is not determined yet. Eight specific disorders related to central sensitization are suggested to be restless leg syndrome, chronic fatigue syndrome, fibromyalgia, temporomandibular disorder, migraine or tension headache, irritable bowel syndrome, multiple chemical sensitivities, and whiplash injury; non-specific emotional disorders related to central sensitization include anxiety or panic attack and depression. These central sensitization pain syndromes are overlapped to previous functional pain syndromes which are unlike organic pain syndromes and have emotional components. Therefore, nociplastic pain can be understood as chronic altered nociception related to central sensitization including both sensory components with nociceptive and/or neuropathic pain and emotional components. Nociplastic pain may be developed to explain unexplained chronic pain beyond tissue damage or pathology regardless of its origin from nociceptive, neuropathic, emotional, or mixed pain components.

  • Background: Migraine headaches are the second leading cause of disability worldwide and are responsible for significant morbidity, reduction in the quality of life, and loss of productivity on a global scale. The purpose of this systematic review and meta-analysis was to evaluate the efficacy of ketamine on migraines and other primary headache disorders compared to placebo and other active interventions, such as midazolam, metoclopramide/diphenhydramine, and prochlorperazine/diphenhydramine. Methods: An electronic search of databases published up to February 2021, including Medline via PubMed, EMBASE, Web of Science, and Cochrane Library, a hand search of the bibliographies of the included studies, as well as literature and systematic reviews found through the search was conducted to identify randomized controlled trials (RCTs) investigating ketamine in the treatment of migraine/headache disorders compared to the placebo. The authors assessed the risk of bias according to the Cochrane Handbook guidelines. Results: The initial search strategy yielded 398 unduplicated references, which were independently assessed by three review authors. After evaluation, this number was reduced to five RCTs (two unclear risk of bias and three high risk of bias). The total number of patients in all the studies was 193. Due to the high risk of bias, small sample size, heterogeneity of the outcomes reported, and heterogeneity of the comparison groups, the quality of the evidence was very low. One RCT reported that intranasal ketamine was superior to intranasal midazolam in improving the aura attack severity, but not duration, while another reported that intranasal ketamine was not superior to metoclopramide and diphenhydramine in reducing the headache severity. In one trial, subcutaneous ketamine was superior to saline in migraine severity reduction; however, intravenous (I.V.) ketamine was inferior to I.V. prochlorperazine and diphenhydramine in another study. Conclusion: Further double-blind controlled studies are needed to assess the efficacy of ketamine in treating acute and chronic refractory migraines and other primary headaches using intranasal and subcutaneous routes. These studies should include a long-term follow-up and different ketamine dosages in diagnosed patients following international standards for diagnosing headache/migraine.

  • Background: Prevalence of chronic pain and its association with demographic characteristics have been reported by different studies from different geographical regions in the world. However, data from many Middle East countries including Iran (especially southern Iran) are scare. The aim of the present study was to demonstrate the prevalence of chronic pain and its association with demographic, psychological and socioeconomic factors in an Iranian population. Methods: In this population-based survey, the target population was comprised of subjects aged 20 to 85 years residing in Jahrom, southern Iran during 2009-2011. All eligible subjects were invited to participate in the study. Before a detailed questionnaire was given; face to face interviews were done for each individual. Results: There were 719 men and 874 women with an average age of 40.5 years at the onset of the study. Among the study population, 38.9% (620/1,593) complained of chronic pain, of whom 40.8% (253/620) were men and 59.2% (367/620) were women. Foot and joint pain were observed in 31.9%. Hip and spine pain, migraine and tension headaches, heart pain, and abdomen pain were observed in 21.5%, 15.5%, 9.5%, and 8.0% of chronic pain cases, respectively. There was a significant association among the covariables age, sex, overweight, educational level, income, and type of employment with chronic pain as the dependent variable (P < 0.0001). Conclusions: Our findings show the prevalence of chronic pain and its association with demographic, psychological and socioeconomic factors. Individuals with low incomes and less education became accustomed to pain due to a lack of knowledge.

  • Objectives Ethanol is a potent inhibitor of muscle protein synthesis. Muscle mass is regulated by the balance between rates of protein synthesis and protein breakdown. Both acute and chronic alcohol consumption inhibits synthesis to a greater extent than degradation. Protein synthesis is more intensely decreased in type II fibers than in type I fibers. Apoptosis has been shown to occur frequently in a variety of tissues in response to chronic alcohol feeding. Increased muscle fiber apoptosis has been shown in alcoholics with myopathy. Pueraria radix has been used for many disorders such as fevers, gastrointestinal disorders, muscle aches, allergies, respiratory problems, skin problems, high blood pressure, migraine headaches, lowering cholesterol and treating chronic alcoholism. We therefore tested the hypothesis that oral treatment with Pueraria radix could reduce the ethanol-induced muscle atrophy. Methods Young male Sprague-Dawley rats were orally given 25% ethanol (5 ml/kg, body weight) daily with Ethanol for 4 weeks. Normal group was similarly administrated with saline. The Rats of Pueraria radix treated group (EtOH+PR) were orally administrated Pueraria radix water extract, and rats of EtOH group were given with the vehicle only. After 4 week, the morphology of gastrocnemius and plantaris muscles were assessed by hematoxylin and eosin staining. The immunoreactivities of pre-apoptotic BAX and anti-apoptotic Bcl-2 proteins were also measured. Results The muscles from rats of EtOH group represented a significant reduction in average cross section area compared to Normal group. EtOH+PR group had increased fiber compared to the EtOH group. Moreover, to investigate the ethanol-induced muscular apoptosis, the immunohistochemical analysis of Bax and Bcl-2 was carried out. The treatment with Pueraria radix (EtOH+PR) significantly decreased BAX expression and increased Bcl-2 expression 4 weeks after ethanol administration when compared with Normal group. Conclusions These results suggest that Pueraria radix water extract has protective effects on chronic alcohol induced myopathy.

  • Objectives : There has been a considerable debate about how to best control for placebo effects in clinical trials of acupuncture. Recently several sham needles were developed and validated. This study aimed at summarising the validation studies of these needles and evaluating the outcomes of the randomised controlled trials (RCTs) using them. Methods : Computerised literature searches were performed using 'acupuncture' AND 'placebo OR sham' with a limitation of the results to RCTs in Medline via PubMed and the Cochrane Library. Only formally validated sham needle controlled studies were included. Data were extracted regarding study design, condition, sample size, credibility testing, intervention and outcomes. Methodological quality was assessed using a modified Jadad scale. Results : Three validated sham needles by Streitberger, Park, and Fink, were identified. Acupuncture's effectiveness for various conditions was tested using these needles in 12 RCTs. Real acupuncture was superior to sham acupuncture for rotator cuff tendonitis and hypertension. No significant differences between real acupuncture and sham acupuncture emerged for chemotherapy-related nausea and vomiting, postoperative nausea and vomiting, menstrually related migraine, acute stroke rehabilitation, chronic/episodic tension-type headache, neutrophil respiratory burst in healthy volunteers, alcohol withdrawal symptoms and chronic poststroke leg spasticity. Conclusions : The new sham devices have been adequately validated and may be useful tools for investigating specific research question. In spite of the sham needle's limits, the results of RCTs using such devices tend to suggest that the clinical effects of acupuncture are largely due to a placebo response.

  • Objectives : The purpose is to introduce the recent large-scale clinical researches for safety, efficacy and effectiveness of acupuncture in Germany. Results : In 2000, the German Federal Committee of Physicians and Health insurer proposed that large research initiatives on acupuncture, Acupuncture Model Projects(Modellvorhaben Akupunktur), could be conducted by health insurance companies for several pain that acupuncture is syndromes to justify the insurance-based reimbursement. Accordingly, 4 clinical researches were carried out; the Acupuncture Safety and Health economics studies(ASH), the Acupuncture Randomised Trial(ART), the Acupuncture in Routine Care studies(ARC), and the German Acupuncture trial(GERAC). Meanwhile, ASH is a prospective observational study for safety and costs. ART and GERAC are composed of RCTs for efficacy. ARC includes 6 pragmatic RCTs with additional non-randomized cohort study for effectiveness. We investigated the papers related to them and discussed about the outcomes. The researches showed that acupuncture is effective in practice for several chronic conditions such as migraine, tension-type headache, chronic low back pain, osteoarthritis of knee, dysmenorrhea, and allergic rhinitis. Based in part on them, the German health authorities decided that acupuncture would be included into routine reimbursement by social health insurance funds for chronic low back pain and chronic osteoarthritis of the knee in 2006. Conclusions : The German clinical researches may suggest the clues for establishing the evidence of acupuncture treatment.

  • The usages of botulinum toxin were most commonly for the treatment of spasmodic dysphonia in the otolaryngology field. It has been not only widely used in otolaryngology-Head Neck surgery but also plastic surgery, ophthalmology, rehabilitation medicine, and orthopedics. Now botulinum toxin is used such as blepharospasm (excessive blinking), strabismus, cosmetic, muscle spasms, upper motor neuron syndrome, severe primary axillary hyperhidrosis (excessive sweating), cervical dystonia (spasmodic torticollis), chronic migraine, bruxism, and achalasia. The indication of this drug still gradually expanding with the times. In this articles, the author will demontrate how to use the botulinum toxin for treating cricopharyngeal spasm, arytenoid dislocation, sialocele, Frey syndrome, contact granuloma, bilateral vocal fold paralysis, and mutaional falsetto instead of conventional surgical treatment.
