Investigation of the Phenomenon of Propagated Sensation along the Channels in the Upper Limb Following Administration of Acupuncture and Mock Laser

© 2017 Background Similar to De Qi psychophysical responses, propagated sensation along the channels (PSC) is considered an important phenomenon in traditional Chinese acupuncture. In acupuncture clinical trials, different acupuncture manipulation techniques are used to enhance the propagation of sensation along the channels to facilitate an optimum therapeutic result. Aim To examine and compare the PSC reported by participants in a clinical trial following the administration of acupuncture and inactive mock laser. Methods The study was embedded in a two-arm parallel design multicenter, randomized clinical trial, the Tennis Elbow Acupuncture—International Study—China, Hong Kong, Australia, Italy (TEA IS CHAI). Needle sensations were measured using a validated instrument, the Massachusetts General Hospital Acupuncture Sensation Spreading Scale. Ninety-six participants with lateral elbow pain were randomly allocated into two groups in a 1:1 ratio; the acupuncture treatment group (n = 47) and the mock laser control group (n = 49). Participants in both groups received the intervention at two acupoints, LI10 and LI11, consisting of 2 minutes of either standardized needle manipulation or mock laser at each acupoint with a rest period between each intervention period. Data were collected immediately following the interventions at the first and the ninth session within the clinical trial. Results Although participants in both groups perceived PSC radiating to similar sites along the upper limb, the frequency of the reported radiation sites among the two intervention groups for both radiation up the limb (p < 0.05) and radiation down the limb (p < 0.001) were statistically significantly different. Among the radiating sensation sites recorded within the two study groups, the sensations were reported as radiating a greater distance down the forearm to the wrist compared to up the arm. Evaluation of PSC across the four study sites revealed a statistically significant difference in frequency of the reported radiation down the limb sites in each study group and radiation up the limb sites only in control group only (p < 0.001). Conclusion The findings of the study demonstrated that the PSC phenomenon is not just associated with needling but can be perceived when using a mock laser.

Unusual Skin Toxicity after a Chemotherapic Combination

As known calciphylaxis (CPX) is a rare condition involving subcutaneous vascular calcification and cutaneous necrosis, mostly observed in patients with renal failure. However CPX may also appear in patients affected by polymyositis, Sjogren syndrome, Lupus Erythematosus systemicus, Sarcoidosis and rheumatoid arthritis, especially in children. Clinically CPX can present itself as subcutaneous nodules, infiltrate plaques or purpuric-like and livedo-like plaques, while in the late stages necrotic ulcers (with a bizarre shape and severe pain) may be the main cutaneous manifestations

Protocol for Acupuncture Treatment of Lateral Elbow Pain: A Multisite Randomised Controlled Trial in China, Hong Kong, Australia, and Italy

© 2016 Christopher Zaslawski et al. Background. Lateral elbow pain is one of the most common musculoskeletal pains associated with the upper limb and has an estimated population incidence of 1-3%. Methods/Design. This study protocol is for a multisite randomised controlled study and is designed to evaluate the clinical efficacy of acupuncture in the treatment of chronic (over three months' duration) lateral elbow pain. Four study sites, in the People's Republic of China, Hong Kong, Italy, and Australia, will recruit 24 participants each. A total of 96 participants will be randomised to either an acupuncture group or a sham laser control group. The primary outcome measure will be the Disabilities of Arm, Shoulder, and Hand questionnaire with secondary outcome measures of Pain-Free Grip Strength Test, Muscle Tension Test, and a pain visual analogue scale. Discussion. Key features for conducting a multisite international acupuncture randomised clinical trial have been detailed in this protocol. Trial Registration. This trial is registered at Australian and New Zealand Clinical Trial Registry ACTRN12613001138774 on 11 October, 2013

Acupuncture and moxibustion for lateral elbow pain: A systematic review of randomized controlled trials

Background: Acupuncture and moxibustion have widely been used to treat lateral elbow pain (LEP). A comprehensive systematic review of randomized controlled trials (RCTs) including both English and Chinese databases was conducted to assess the efficacy of acupuncture and moxibustion in the treatment of LEP.Methods: Revised STRICTA (2010) criteria were used to appraise the acupuncture procedures, the Cochrane risk of bias tool was used to assess the methodological quality of the studies. A total of 19 RCTs that compared acupuncture and/or moxibustion with sham acupuncture, another form of acupuncture, or conventional treatment were included.Results: All studies had at least one domain rated as high risk or uncertain risk of bias in the Cochrane risk of bias tool. Results from three RCTs of moderate quality showed that acupuncture was more effective than sham acupuncture. Results from 10 RCTs of mostly low quality showed that acupuncture or moxibustion was superior or equal to conventional treatment, such as local anesthetic injection, local steroid injection, non-steroidal anti- inflammatory drugs, or ultrasound. There were six low quality RCTs that compared acupuncture and moxibustion combined with manual acupuncture alone, and all showed that acupuncture and moxibustion combined was superior to manual acupuncture alone.Conclusion: Moderate quality studies suggest that acupuncture is more effective than sham acupuncture. Interpretations of findings regarding acupuncture vs. conventional treatment, and acupuncture and moxibustion combined vs. manual acupuncture alone are limited by the methodological qualities of these studies. Future studies with improved methodological design are warranted to confirm the efficacy of acupuncture and moxibustion for LEP. © 2014 Gadau et al.; licensee BioMed Central Ltd

Acupuncture Treatment of Lateral Elbow Pain: A Nonrandomized Pilot Study

© 2016 Yan-Song Liu et al. In planning for a large-scale multicenter trial to evaluate the effect of acupuncture for the treatment of lateral elbow pain, a pilot study was conducted. This was a prospective, investigator- and patient-blinded, nonrandomized, placebo controlled trial. Subjects were evaluated at baseline, before fourth, seventh, and ninth treatment, and at a two-week posttreatment follow-up. The treatment group received unilateral acupuncture at LI 10 and LI 11 at the affected side with manual needle manipulation; the control group received sham-laser acupuncture at the same acupoints. Measures included (i) disabilities of the arm, shoulder, and hand (DASH) questionnaire, (ii) pain-free grip strength (PFGS), and (iii) a visual analogue scale (VAS) for pain. Significant differences in DASH score, PFGS, and VAS between treatment and control group were found at the ninth treatment (n = 20 for each group, P < 0.05). Only DASH showed significant differences compared to the control for all the measurement time points after treatment commenced and appears to be a sensitive and appropriate primary outcome measure for the future multisite trial. Results from this pilot study provided relevant information about treatment efficacy, credibility of control treatment, and sensitivity of different outcome measures for the planning of the future trial

Accuratezza dell'ecografia endorettale nel cancro del retto dopo radio-chemioterapia

L’obiettivo che ci siamo posti è di valutare il ruolo dell’ecografia transrettale (TRUS) nella seconda stadia-zione del paziente affetto da cancro del retto localmente avanzato sottoposto a radiochemioterapia. In particolare, vogliamo mostrare come le modificazioni infiammatorie indotte dal trattamento neoadiu-vante riducano la capacità di questa metodica di individuare correttamente il coinvolgimento degli strati parietali del retto. Un gruppo di 16 pazienti affetti da cancro del retto in cui una prima indagine ecografica ha rilevato un coin-volgimento del grasso perirettale (uT3) ed un’alta probabilità di coinvolgimento linfonodale sono stati trat-tati mediante radioterapia (50 Gy in 28 frazioni giornaliere) ed infusione continua di 5-FU e successivamente sottoposti ad ulteriore indagine ecografica endorettale che ha consentito di valutare l’efficacia del trattamento neoadiuvante, mentre il trattamento chirurgico è stato deciso sulla base del risultato della prima indagine. Confrontando con l’istologia i risultati ottenuti con la seconda ecografia, abbiamo riscontrato un’accuratezza diagnostica complessiva pari al 48% per l’infiltrazione parietale ed inferiore al 60% per quanto riguarda il coinvolgimento linfonodale. In seguito al trattamento radioterapico, le alterazioni della morfologia degli strati ecografici della parete rettale possono mimare lesioni neoplastiche ma essere in realtà costituite da residui fibrotici o necrotici privi di cellule tumorali oppure di estensione limitata rispetto a quanto atteso e il numero di linfonodi di tipo reattivo è probabilmente aumentato
