Dry Needling for Spine Related Disorders: a Scoping Review

Introduction/Background: The depth and breadth of research on dry needling (DN) has not been evaluated specifically for symptomatic spine related disorders (SRD) from myofascial trigger points (TrP), disc, nerve and articular structures not due to serious pathologies. Current literature appears to support DN for treatment of TrP. Goals of this review include identifying research published on DN treatment for SRD, sites of treatment and outcomes studied. Methods: A scoping review was conducted following Levac et al.’s five part methodological framework to determine the current state of the literature regarding DN for patients with SRD. Results: Initial and secondary search strategies yielded 55 studies in the cervical (C) region (71.43%) and 22 in the thoracolumbar-pelvic (TLP) region (28.57%). Most were randomized controlled trials (60% in C, 45.45% in TLP) and clinical trials (18.18% in C, 22.78% in TLP). The most commonly treated condition was TrP for both the C and TLP regions. In the C region, DN was provided to 23 different muscles, with the trapezius as treatment site in 41.88% of studies. DN was applied to 31 different structures in the TLP region. In the C region, there was one treatment session in 23 studies (41.82%) and 2–6 treatments in 25 (45.45%%). For the TLP region, one DN treatment was provided in 8 of the 22 total studies (36.36%) and 2–6 in 9 (40.9%). The majority of experimental designs had DN as the sole intervention. For both C and TLP regions, visual analogue scale, pressure pain threshold and range of motion were the most common outcomes. Conclusion: For SRD, DN was primarily applied to myofascial structures for pain or TrP diagnoses. Many outcomes were improved regardless of diagnosis or treatment parameters. Most studies applied just one treatment which may not reflect common clinical practice. Further research is warranted to determine optimal treatment duration and frequency. Most studies looked at DN as the sole intervention. It is unclear whether DN alone or in addition to other treatment procedures would provide superior outcomes. Functional outcome tools best suited to tracking the outcomes of DN for SRD should be explored.https://doi.org/10.1186/s12998-020-00310-

Constitutive modelling of skin ageing

The objective of this chapter is to review the main biomechanical and structural aspects associated with both intrinsic and extrinsic skin ageing, and to present potential research avenues to account for these effects in mathematical and computational models of the skin. This will be illustrated through recent work of the authors which provides a basis to those interested in developing mechanistic constitutive models capturing the mechanobiology of skin across the life course

Utilisation of dental services in a university hospital palliative and long-term care unit in Geneva

OBJECTIVES: Dental care plays an important role in the multidisciplinary approach, which is used in palliative and long-term care to address the complex needs of terminally ill patients. The aim of this study was to assess the utilisation of dental services in a University Hospital Palliative and Long-term Care Unit. MATERIAL AND METHOD: Over an observation period of 13 months, structured questionnaires were filled in after each dental appointment. The survey covered three main topics: the initiation and incentive from the dental consultation, particular difficulties because of the patient's health or the hospital's organisation as well as the accomplished treatment. RESULTS: Two hundred and seventy-five questionnaires from a total of 102 patients were available for analysis. The patients' median age was 83 years (SD 10.3, range 49-101 years), 63 were female, 39 male. A majority of first appointments were initiated by a physician (n = 49 of 102), mainly because of pain (n = 62 of 275). 10.5% of the appointments were cancelled on the same day. Only one-fifth of the patients were able to reach the practice on foot. Six used a walking stick and 54 relied on a wheelchair. Eighteen patients needed to be seen in their bed. The most frequently performed procedures were extractions and removal of denture sore spots (n = 67 of 275) followed by the manufacturing of new dentures (n = 38 of 275). In more than 17% of the appointments, no particular treatment was performed. CONCLUSION: The utilisation of dental services in terminally ill and severely compromised elderly patients shown justifies a dental service in a palliative care or geriatric hospital setting. The particular dental work profile requires a practitioner with empathy and professional experience

Efficacy and mode of action of external trigeminal neurostimulation in migraine

Introduction: Available preventive drug treatments for migraine lack complete efficacy and often have unpleasant adverse effects. Hence, their clinical utility and therapeutic adherence are limited. Noninvasive neurostimulation methods applied over various peripheral sites (forehead, mastoid, upper arm, cervical vagus nerve) have raised great interest because of their excellent efficacy/tolerance profile. Among them external trigeminal nerve stimulation (eTNS) was first to obtain FDA approval for migraine therapy. Areas covered: All clinical trials of eTNS as preventive or acute migraine treatment published in extenso or presented at congresses are reviewed. The paper analyzes neuroimaging and neurophysiological studies on mechanisms of action of eTNS. As many of these studies point toward the anterior cingulate cortex (ACC) as a likely eTNS target, the paper scrutinizes the available literature on the ACC implication in migraine pathophysiology. Expert commentary: eTNS is a viable alternative to standard pharmacological antimigraine strategies both for prevention and abortive therapy. eTNS could chiefly exert its action by modulating the perigenual ACC, which might also be of interest for treating other disorders like fibromyalgia or depression. It remains to be determined if this might be a common mechanism to other peripheral noninvasive neurostimulation methods
