Abstract:
Background: Myofascial pain is defined as pain that originates from myofascial trigger points in skeletal muscle. It is prevalent in regional musculoskeletal pain syndromes, either alone or in combination with other pain generators. The myofascial pain syndrome is one of the largest groups of under diagnosed and under treated medical problems encountered in clinical practice. Trigger points are commonly seen in patients with myofascial pain which is responsible for localized pain in the affected muscles as well as referred pain patterns. Correct needle placement in a myofascial trigger point is vital to prevent complications and improve efficacy of the trigger point injection to help reduce or relieve myofascial pain. In obese patients, these injections may not reach the target tissue. In the cervicothoracic spine, a misguided or misplaced injection can result in a pneumothorax. Here, we describe an ultrasound-guided trigger point injection technique to avoid this potential pitfall. Office based ultrasound-guided injection techniques for musculoskeletal disorders have been described in the literature with regard to tendon, bursa, cystic, and joint pathologies. For the interventionalist, utilizing ultrasound yields multiple advantages technically and practically, including observation of needle placement in real-time, ability to perform dynamic studies, the possibility of diagnosing musculoskeletal pathologies, avoidance of radiation exposure, reduced overall cost, and portability of equipment within the office setting. To our knowledge, the use of ultrasound guidance in performing trigger point injection in the cervicothoracic area, particularly in obese patients, has not been previously reported. Methods: A palpable trigger point in the cervicothoracic musculature was localized and marked by indenting the skin with the tip of a plastic needle cover. The skin was then sterile prepped. Then, using an ultrasound machine with sterile coupling gel and a sterile latex free transducer cover, the musculature in the cervicothoracic spine where the palpable trigger point was detected was visualized. Then utilizing direct live ultrasound guidance, a 25-gauge 1.5 inch needle connected to a 3 mL syringe was placed into the muscle at the exact location of the presumed trigger point. This guidance helps confirm needle placement in muscle tissue and not in an adipose tissue or any other non-musculature structure. Results: The technique is simple to be performed by a pain management specialist who has ultrasound system training. Conclusion: Ultrasound-guided trigger point injections may help confirm proper needle placement within the cervicothoracic musculature. The use of ultrasound-guided trigger point injections in the cervicothoracic musculature may also reduce the potential for a pneumothorax by an improperly placed injection. Key words: Trigger point injection, myofascial pain, ultrasound

Full text
Abstract:
Xylem embolism repair is preceded by starch depolymerisation in vessel-associated cells (VAC) of Laurus nobilis L. (laurel) twigs, but the primary signal triggering such a process is still unknown. We tested the hypothesis that conduit wall vibrations during cavitation may be sensed by VAC inducing starch-to-sugar conversion. Twigs of laurel from watered or stressed plants were exposed to ultrasound for 60 min to simulate acoustic waves emitted by cavitating conduits. Preliminary tests showed that ultrasound caused no damage to cell membrane integrity nor did they cause xylem embolism. The number of VAC with high starch content (HSC-cells) was estimated microscopically by counting the cells with more than 50% of their lumen filled with starch granules. Sonication had no effect on HSC-cells in twigs from watered plants while it induced a drop in the percentage HSC-cells from 80 to 40% in twigs from stressed plants, at the ultrasound source location. No effect was recorded in these twigs 20 mm from the ultrasound source. Sonication was a good simulator of cavitation in inducing starch depolymerisation which suggests a possible bio- physical nature for the signal initiating embolism repair.

Abstract:
Abstract Trigger points as a cause of musculoskeletal or myofascial pain syndrome is well documented. Trigger points (Tr Ps) are tender and hypersensitive nodules seen in skeletal muscles which develop as a result of sudden or repetitive trauma to the muscles. They cause contractile state of a muscle with local or radiating pain. Active trigger points cause intense pain with limitation of movements of the muscles. The treatment involves deactivating the trigger points, usually done by various methods. Most common practice is myotherapy which involves deep tissue massage which is painful and time consuming. Dry needling and needling with anaesthetic injaection have been successfully used by many. Recently, ultrasound guidance is used to locate the trigger points and to accurately place the needle in to them to deactivate, thus preventing complications of blind procedures.

Abstract:
Trigger point injections are commonly practised pain interventional techniques. However, there is still lack of objective diagnostic criteria for trigger points. The mechanisms of action of trigger point injection remain obscure and its efficacy remains heterogeneous. The advent of ultrasound technology in the noninvasive real-time imaging of soft tissues sheds new light on visualization of trigger points, explaining the effect of trigger point injection by blockade of peripheral nerves, and minimizing the complications of blind injection.

Abstract:
Background:Muscles and fascia are the major source of pain in rheumatic diseases. Dry needling under ultrasound guidance (DN-US) is a crucial therapeutic approach to treat muscle pain [1,2], the definition `myo-fascial` calls for searching trigger points (TrPs) in fascia to improve the treatment effectiveness.Objectives:Aim was to evaluate the relevance of fascial ultrasound for DN-US in myo-fascial pain.Methods:We included 36 patients (21 females, 20-69 years old) with myofascial pain different localisations (low back, limbs, shoulder, neck pain), postural imbalance; did DN-US protocol according to R. Bubnov [1]: trigger points were identified according, fine (28G) steel needle DN-US was applied. Additionally considered fascial structures for detecting areas of abnormalities (hypervascularity, heterogeinity, hypomotility, adhesions) aka `trigger points` and potental nerve compression/irritation and did precise DN-US where appropriate.Results:In all patients movement restored and pain decreaed after muscles DN; in 30 patients additionally we detected and did successful DN-US the major fascial points as follows: thoracolumbar fascia, sacroiliac joint, pelvis ligaments, rotator cuff; potential nerve compressions (e.g., arcade of Frochse, soleus arcade); nerve sheath surrounding nerves (sciatic nerve, brachial plexus) and vessels (thoracic outlet syndrome), smaller fascia, joint capsule thickening. We detected higher rates of motility, improvement postural balance and pain decrease, fewer sessions needed in patients after extensive protocol.Conclusion:Fascia dry needling is accessible and effective method for myo-fascial pain treatment, may provide additional mechanical benefit and help to maintain treatment effect. Affected fascia can be considered as relevant trigger points, specific ultrasound symptoms should be validated.References:[1]Bubnov R Trigger Points Dry Needling Under Ultrasound Guidance for Low Back Pain Therapy.

Abstract:
Abstract Introduction Myofascial pain syndrome is an important and prevalent public health problem. The lack of consensus on the diagnostic criteria, together with the scarce reliability of the manual detection of the manual detection of myofascial trigger points (MTrPs) point to the need to develop objective methods to enable confirmation of the presence of MTrPs. Ultrasound is an accessible method which enables the assessment of tissue properties in real time, helping to characterize the MTrP, understand its physiopathology and define its diagnosis. Aims To identify observational studies researching the use of ultrasound in the assessment of MTrPs. Also, to learn about and compile the advances in the study of the characteristics of MTrPs and their sonographic diagnosis. Material and Methods A systematic review was performed by two independent reviewers, searching biomedical databases using terms related with “ultrasound” and “trigger points”. Observational studies were selected evaluating the characteristics of MTrPs. Subsequently, an analysis of the diagnostic quality of studies was performed using the QAREL scale and a study of the methodological quality took place based on the Downs and Black scale. Furthermore, an assessment of the reproducibility of the acquirement of images was performed, via the analysis of the description of the ultrasound method. The risk of bias was evaluated according to the Cochrane guidelines. Results 18 studies based on B Mode methods, elastography and Doppler, were included in the review. The anatomic regions which were most explored were the cervical area and the upper limb, evaluated in 14 of the 18 papers. The most common muscle was the upper trapezius (61%). Two articles were located corresponding to the lumbar region and one article concerned the lower limb. The analysis of the sonographic method showed a low level, 5 of the 9 items did not overcome 17% of fulfillment, in 3 papers the frequency was below 6%. The QAREL scale also displayed low levels, only 3 items out of 11. Inter-evaluator blinding, correct testing and statistical methods were fulfilled in over 50%. The mean score obtained by the studies in the Downs and Black scale was 5.4 points out of 10, ranging between 2 and 7 points. The risk of bias according to the Cochrane guidelines was mid- to high. Conclusion Important steps have been taken in the study of the sonograhic characteristics of the MTrP, however, we are still far from standardizing the use of the same as a diagnostic method. The poor results in the quality analysis of the present study suggest caution in the interpretation of the present findings. Future research is necessary, including different anatomic regions, analytic methods, better defined exploration protocols and more robust reliability studies for the different methods available.

Abstract:
Extracellular vesicles (EVs)-carrying biomolecules derived from parental cells have achieved substantial scientific interest for their potential use as drug nanocarriers. Ultrasound (US) in combination with microbubbles (MB) have been shown to trigger the release of EVs from cancer cells. In the current study, the use of microbubbles-assisted ultrasound (USMB) to generate EVs containing drug cargo was investigated. The model drug, CellTracker™ green fluorescent dye (CTG) or bovine serum albumin conjugated with fluorescein isothiocyanate (BSA FITC) was loaded into primary human endothelial cells in vitro using USMB. We found that USMB loaded CTG and BSA FITC into human endothelial cells (HUVECs) and triggered the release of EVs containing these compounds in the cell supernatant within 2 h after treatment. The amount of EV released seemed to be correlated with the increase of US acoustic pressure. Co-culturing these EVs resulted in uptake by the recipient tumour cells within 4 h. In conclusion, USMB was able to load the model drugs into endothelial cells and simultaneously trigger the release of EVs-carrying model drugs, highlighting the potential of EVs as drug nanocarriers for future drug delivery in cancer.

Abstract:
Myofascial trigger point is a hyperirritable nodule present in a palpable taut band of skeletal muscle, often results from muscle injury or repetitive strain that cause pain and tightness. Myofascial trigger points are one of the most common causes of chronic neck pain. This study aims to determine the efficacy of ischemic compression in comparison with myofascial stretching on trigger points of trapezius muscle for reduction of pain and spasm. Randomized Control Trial. The study was conducted in Ziauddin Hospital. 96 participants were enrolled in the study. Participants were divided into two groups equally and randomly, Group (A) an intervention group treated with hot pack, ultrasound therapy and ischemic compression, Group (B) a control group treated with hot pack, ultrasound therapy and myofascial stretching. This regime was followed thrice a week for three weeks. Statistically significant (P < 0.05) changes in the values were found in Group A and Group B for Visual Analog scale and Penn spasm frequency scale post treatment. The results showed that there is significant difference found after both interventions for the treatment of pain and spasm caused by myofascial trigger point. It cannot be said that ischemic compression is more effective than myofascial stretching for the treatment of myofascial trigger points of trapezius muscle.

Abstract:
Myofascial pain syndrome (MPS) is characterized by the presence of clinically detected myofascial trigger points (MTrPs). Diagnostic ultrasound (US) has been proposed as a method to strengthen the reliability of MTrP localization, thus potentially improving the efficacy and safety profile of interventional procedures. The objective is to evaluate the benefit and safety profile of any US-guided interventional procedure for MPS. Medline, Embase, PubMed, the Allied and Complementary Medicine Database (AMED), and Web of Science were systematically searched from their inception to May 2020 for any randomized controlled trial that evaluated treatment benefit and safety of any US-guided interventional procedure for MPS. The primary outcome of interest was pain severity. Additional outcomes of interest were function and adverse effects. The risk of bias was assessed using the Risk of Bias V.2.0 tool. eleven studies met all inclusion and exclusion criteria. Two studies (n=174) with a high risk of bias revealed some evidence supporting US guidance over blinded interventions for improvement in pain and function. Eight studies (n=483) with varying risks of bias were of head-to-head comparisons of different US modalities. These studies revealed that US-guided local anesthetic injections were inferior to US-guided pulse radiofrequency and US-guided dry needling (DN). US-guided DN was also found to be superior to US-guided platelet-rich-plasma injections but inferior to US-guided miniscalpel. Meanwhile, one study (n=21) with some concerns of bias found that US-guided local anesthetic injections were superior to non-steroidal anti-inflammatory drugs for pain outcomes and fewer adverse events. All US-guided procedures resulted in zero or minimal self-limited adverse events. Issues with clinical relevance, limited sample sizes, and small point estimates warrant more high-quality research to better characterize the possible value of US-guided injections.

Abstract:
Introduction. Trigger finger is ten times less common than trigger thumb in infants and children and, unlike trigger thumb, may arise from a variety of underlying causes. To our knowledge, we describe the first case of pediatric trigger finger secondary to an extraskeletal chondroma. Case Presentation. We report the case of an 11-year-old girl presenting with a typical history of triggering of the fourth finger, in whom a nodule attached to the flexor digitorum superficialis was found; clinical, ultrasound, and operative findings are described. Histological analysis was diagnostic of extraskeletal chondroma, also known as chondroma of soft tissues. Conclusion. This is a very uncommon benign cartilaginous tumor, mostly reported in patients aged 30 to 60 years (just one pediatric extraskeletal chondroma of the hand has been described), and presentation with trigger finger has been reported just once, in a 76-year-old man. This condition should be considered in the differential diagnosis of pediatric trigger finger.
