Chronic myofascial pain of the cervical spine and shoulders is commonplace in clinical practice and is often related to adverse posture during work conditions in our life style. The diagnosis is clinical and injections of the neck/shoulder muscles, especially the upper trapezius, are commonly performed in a blinded way. The anatomy of the posterior compartment of the neck is complicated and several neurovascular structures are located nearby the trapezius and levator scapulae muscles in the inter-fascial planes...

STUDY DESIGN: Animal experiment: a rat model of lumbar disc herniation (LDH) induced painful radiculopathies. OBJECTIVE: To investigate the role and mechanism of AMP-activated protein kinase (AMPK) in dorsal root ganglia (DRG) neurons in LDH-induced painful radiculopathies. SUMMARY OF BACKGROUND DATA: Overactivation of multiple pain signals in DRG neurons triggered by LDH is crucial to the development of radicular pain. AMPK is recognized as a cellular energy sensor, as well as a pain sensation modulator, but its function in LDH-induced pain hypersensitivity remains largely unknown...

BACKGROUND: Irritable bowel syndrome (IBS) is a highly prevalent condition. It is diagnosed on the basis of chronic symptoms after the clinical and/or investigative exclusion of organic diseases that can cause similar symptoms. There is no reproducible non-invasive test for the diagnosis of IBS, and this raises diagnostic uncertainty among physicians and hinders acceptance of the diagnosis by patients. Functional gastrointestinal (GI) syndromes often present with overlapping upper and lower GI tract symptoms, now believed to be generated by visceral hypersensitivity...

Children with acute pancreatitis may develop chronic abdominal wall pain after resolution of clinical, laboratory, and radiographic signs of disease. We describe a 13-year-old boy who underwent an unrevealing, complex diagnostic evaluation for persistent abdominal pain after resolution of acute pancreatitis. His pain required an extended leave of absence from school and nasogastric tube feeds. After receiving abdominal nerve blocks and trigger point injections, he experienced near-complete resolution of pain with normalization of eating habits and daily function...

Objective: This study compared urinary 6-sulfatoxymelatonin (aMT6s) over 24 hours among fibromyalgia (FM), major depression disorder (MDD), and healthy control (HC) groups, and examined whether rhythm is correlated with depressive symptoms. To answer this question we compared the rhythm of urinary aMT6s secretion among each group in four time series: morning (06:00-12:00 hours), afternoon (12:00-18:00 hours), evening (18:00-24:00 hours), and night (24:00-06:00 hours). In the FM subjects, we assessed if the rhythm of urinary aMT6s secretion is associated with pain severity, sleep quality, number of trigger points (NTPs), and the pain pressure threshold (PPT)...

Latent myofascial trigger points (MTrP) have been linked to several impairments of muscle function. The present study was conducted in order to examine whether a single bout of self-myofascial release using a foam roller is effective in reducing MTrP sensitivity. Fifty healthy, pain-free subjects (26.8±6 years, 21 men) with latent MTrP in the lateral gastrocnemius muscle were included in the randomized, controlled trial. One week after a familiarization session, they were randomly allocated to three groups: (1) static compression of the most sensitive MTrP using a foam roll, (2) slow dynamic foam rolling of the lateral calf and (3) placebo laser acupuncture of the most sensitive MTrP...

BACKGROUND: Sevoflurane is widely used to anesthetize children because of its rapid action with minimal irritation of the airways. However, there is a high risk of agitation after emergence from anesthesia. Strabismus surgery, in particular, can trigger agitation because patients have their eyes covered in the postoperative period. The aim of this study was to determine whether or not esmolol and lidocaine could decrease emergence agitation in children. METHODS: Eighty-four patients aged 3 to 9 years undergoing strabismus surgery were randomly assigned to a control group (saline only), a group that received intravenous lidocaine 1...

Background: Myofascial trigger points (TrPs) are hyperirritable spots within taut bands of skeletal muscles that elicit local and referred pain when stimulated. Among the variety of techniques used for treating TrPs, dry needling (DN) is the most commonly applied intervention. The physiological mechanisms underlying the effects of DN remain to be elucidated. Objective: To examine changes in skeletal muscle after DN in the area where the TrP is located. Methods: We measured in vivo changes that occur in human skeletal muscle one hour after DN over a TrP with magnetic resonance imaging (MRI) and tensiomyography...

We herein report a teenage girl who had been taking oral contraceptive pills for three months and complained of left lower abdominal pain that had continued for two months. A physical examination indicated anterior cutaneous nerve entrapment syndrome (ACNES), although no abnormality was found in various biochemical and imaging examinations. The pain was only transiently ameliorated by trigger-point injection, and neurectomy surgery was eventually effective. Sex steroids can be involved in the progress of local tissue edema causing ACNES...

Abdominal wall pain (AWP) is a common and underrecognized cause of chronic abdominal pain. The etiology of AWP varies. History and physical examination are critical to an accurate diagnosis of AWP. Trigger point injection using either a corticosteroid, a local anesthetic, or a combination of both often gives relief of pain and is of diagnostic and therapeutic value. Increased awareness of AWP as a cause of chronic, nonvisceral abdominal pain can prevent fruitless searches for intra-abdominal pathology and reduce medical costs...
