PURPOSE: The consolidation of the acromioclavicular (AC) and coracoclavicular (CC) ligament complex after arthroscopically assisted stabilization of acute acromioclavicular joint (ACJ) separation is still under consideration. METHODS: Fifty-five consecutive patients after arthroscopically assisted double-CC-bundle stabilization within 14 days after acute high-grade ACJ separation were studied prospectively. All patients were clinically analysed preoperatively (FU0) and post-operatively (FU1 = 6 months; FU2 = 12 months)...

Many scorpion accidents occur in the Brazilian Amazonian region and are frequently caused by Tityus obscurus. Approximately 5% of the crude venom of this species is composed of short linear, non-disulfide-bridged peptides, which have not been intensively investigated. As a consequence, only a few of these peptides have been structurally and functionally characterized to date. In the present paper, the peptide fraction of the venom was subjected to peptide profiling using an LCMS-IT-TOF/MS and MS(n) system. The analysis detected 320 non-disulfide bond-containing peptides (NDBPs), of which twenty-seven had their sequences assigned; among them, thirteen peptides were characterized, constituting novel toxins in T...

Internationally, rural people have poorer health outcomes relative to their urban counterparts, and primary care providers face particular challenges in rural and remote regions. Drawing on ethnographic fieldnotes and 14 open-ended qualitative interviews with care providers and chronic pain patients in two remote resource communities in Northern Ontario, Canada, this article examines the challenges involved in providing and receiving primary care for complex chronic conditions in these communities. Both towns struggle with high unemployment in the aftermath of industry closure, and are characterized by an abundance of affordable housing...

Neuropathic pain in a chronic post-ischaemic pain (CPIP) model mimics the symptoms of complex regional pain syndrome type I (CRPS I). The administration of bee venom (BV) has been utilized in Eastern medicine to treat chronic inflammatory diseases accompanying pain. However, the analgesic effect of BV in a CPIP model remains unknown. The application of a tight-fitting O-ring around the left ankle for a period of 3 h generated CPIP in C57/Bl6 male adult mice. BV (1 mg/kg ; 1, 2, and 3 times) was administered into the SC layer of the hind paw, and the antiallodynic effects were investigated using the von Frey test and by measuring the expression of neurokinin type 1 (NK-1) receptors in dorsal root ganglia (DRG)...

Splenic tuberculosis (TB) in the form of multiple splenic cold abscesses with perisplenic extensions is a rare disease, especially in an immunocompetent host. It demonstrates diagnostic complexity, which makes identification of the disease difficult. We report a case of an immunocompetent adult male who presented with fever, pain in the left lower chest, decreased appetite, and significant weight loss. On physical examination, he had tenderness in the left lower infra-axillary region and Traube's space dullness without palpable spleen...

Migraine is a prevalent neurovascular disorders with a complex pathophysiology and therapeutic options characterized by important side effects or problems related to drug abuse. No specific biomarkers are recognized to be univocal for this subclinical condition, yet. In this concern microRNAs have been suggested as potentially useful screening/diagnostic tool, and research is underway to recognize the most effective candidate(s). microRNAs, able to regulate immune and neuronal processes are herein reported for both, mice models with multiple induced pain conditions and human subjects...

It has been proposed that Complex Regional Pain Syndrome (CRPS) is a post-traumatic autoimmune disease and we previously observed that B cells are required for the full expression of CRPS-like changes a mouse tibia fracture CRPS model. The current study used the mouse model to evaluate the progression of post-fracture CRPS-like changes in wildtype (WT) and muMT fracture mice lacking B cells and antibodies. The pronociceptive effects of injecting WT fracture mouse serum antibodies into muMT fracture mice were also evaluated...

Calcium waves are generated from the astrocyte endoplasmatic reticulum, in response to neuronal electrochemical stimulation. The waves feed back on neurons, modulating (reinforcing or depressing) their activity and the resulting behavior. How do these waves propagate from the astrocyte endoplasmatic reticulum to the synaptic space and reach neuron membrane channels? An exploratory model is elaborated, on the basis of complex interactions of ions, water negative exclusion zones and charged sites of proteins...

This review of pain management in lung cancer is based on the presentation of four cases of thoracic oncology patients with pain at various stages of their disease. The approach will be multidisciplinary, involving a thoracic oncologist, radiologist, thoracic and orthopaedic spine surgeon, radiation therapist, pain medicine specialist, and palliative care specialist. This multispecialty approach to the management of different painful presentations in thoracic oncology will demonstrate the complexity of each case and the improved patient outcomes which result from the involvement of different disciplines working in concert...

A case of exophthalmos due to zygomatic mucocele in a puppy with ipsilateral segmental maxillary atrophy is reported. A 7-month-old, mixed breed, male dog suffered the sudden-onset of unilateral painful exophthalmos and a gradual swelling of the right temporal region. A compressing, right retrobulbar mass was observed by ultrasound. Computed tomography revealed a large multiloculated cyst-like lesion of the right zygomatic gland projecting into the orbital space, thus displacing the eyeball. The ipsilateral molar part of the maxillary bone was underdeveloped, besides showing crowded, abnormal, multiple, unerupted maxillary molar teeth in the caudal maxillary region...

Chronic orofacial pain is a complex multidimensional experience that produces disability and impairment of normal mandibular function. Overall estimations of chronic orofacial pain prevalence are 7 to 11% of the general population. Temporomandibular disorders (TMDs) are one of the most prevalent chronic orofacial pain conditions, with temporomandibular joint (TMJ) arthralgia accounted for 30.1% of TMD patients. Interventional procedures are often used in pain and palliative medicine to achieve reasonable and cost-effective pain relief...

PURPOSE: Diagnostic challenges are common in clinical practice and diagnostic or classification criteria for musculoskeletal conditions cannot overshadow clinical skills. METHODS: We present the case of a young man who complained of prolonged articular pain and mild swelling of the right ankle in the absence of other remarkable data. Apparently fulfilling the Budapest diagnostic criteria for complex regional pain syndrome, the patient was treated accordingly, but the pain increased over time...

Complex regional pain syndrome (CRPS) constitutes an atypical cause of pain after orthopaedic procedures. To our knowledge, there is a paucity of literature reporting this syndrome after total hip arthroplasty (THR), since only two case reports have been published. We thenceforth describe the clinical outcome of three cases of type-1 CRPS developed after elective THR, two of them initially diagnosed with secondary osteoarthritis whereas the remaining one presented a sequel of a failed osteosynthesis that required conversion to THR...

Complex regional pain syndrome (CRPS) is a chronic pain condition associating sensory, motor, trophic and autonomic symptoms in one limb. Cognitive difficulties have also been reported, affecting the patients' ability to mentally represent, perceive and use their affected limb. However, the nature of these deficits is still a matter of debate. Recent studies suggest that cognitive deficits are limited to body-related information and body perception, while not extending to external space. Here we challenge that statement, by using temporal order judgment (TOJ) tasks with tactile (i...

BACKGROUND AND AIMS: Recent evidence demonstrated that complex regional pain syndrome (CRPS) is associated with a larger than normal somatosensory (S1) representation of the healthy hand. The most intuitive mechanism for this apparent enlargement is increased, i.e. compensatory, use of the healthy hand. We investigated whether enlargement of the S1 representation of the healthy hand is associated with compensatory use in response to CRPS. Specifically, we were interested in whether the size of the S1 representation of the healthy hand is associated with the severity of functional impairment of the CRPS-affected hand...

BACKGROUND: Treatment of neuropathic pain in children is challenging, and requires a multimodal approach of pharmacologic, physical, and psychological therapies; however there is little evidence to guide practice. Amitriptyline and gabapentin are first-line drugs for treating neuropathic pain in adults, yet no studies have examined their efficacy, or compared them directly, to determine which might be better for pain relief and sleep disturbance in children. METHODS: After informed consent was obtained, 34 patients aged 7-18 years diagnosed with complex regional pain syndrome type I (CRPS I) or a neuropathic pain condition were randomly allocated to receive either amitriptyline or gabapentin...

BACKGROUND AND PURPOSE: Complex regional pain syndrome (CRPS) is a challenging complication after surgery or trauma. This study sought to determine the incidence of CRPS after a second inciting event in a previously unaffected extremity in patients with a history of an ongoing CRPS diagnosis in another extremity. METHODS: A retrospective review identified patients with CRPS seen in clinic over a 20-month period. The incidence of CRPS after subsequent surgery or injury in a previous unaffected extremity was determined and compared to an average incidence reported in the literature...
