Chronic pain is suggested to be linked to reorganization processes in the sensorimotor cortex. In the current study, the somatosensory representation of the extremities was investigated in a patient with a complex regional pain syndrome (CRPS) that initially occurred in the right hand and arm and spread later into the left hand and right leg. After the spread, magnetoencephalographic recordings in conjunction with somatosensory stimulation revealed that the clinical symptoms were associated with major changes in the primary somatosensory representation...

INTRODUCTION: The constant increase on the psychosocial demands experienced at work seems to contribute to the increase in health problems such as musculoskeletal pain (MSP). This association may be especially important in low-income and middle-income countries, where there is a large proportion of informal workers among whom there is little research. We analysed the association between psychosocial work risk factors and MSP among formal and informal workers using the First Central American Survey of Working Conditions and Health...

BACKGROUND: Distal radial fractures are one of the most common injuries seen in traumatology. Most are treated conservatively with closed reduction and immobilisation in a plaster cast. However, this method does not always allow for achieving and maintaining normal fracture reduction in unstable fractures. The aim of this study was assess clinical and radiographic outcomes of treatment of distal radial fractures depending on the method used. MATERIAL AND METHODS: A total of 77 postmenopausal female subjects were divided into three subgroups, depending on the treatment methods: 1...

BACKGROUND: Complex Regional Pain Syndrome (CRPS) occurs due to different pathophysiological mechanisms. Presently there is no description of definitive treatment that can resolve the especially recalcitrant motor issues of disability in CRPS-1. CASE REPORT: We have herein described the successful management of motor disability with a multi-modal approach in a patient with CRPS-1 that occurred as a result of a fracture sustained in the lower end of the radius. Sensory/sudomotor/vasomotor symptoms were relieved completely by medications and stellate ganglion block, in two weeks...

AIMS: The non-specialist management of cancer patients is becoming increasingly complex. Acute oncology services (AOS), aiming to provide rapid access to specialist advice, have been shown to improve patient experience and reduce length of inpatient stay. The present study aimed to inform service provision in a district general hospital (DGH) by investigating cancer patients, not on active anti-cancer treatment, where the disease itself precipitated admission. This is a vulnerable group who are potentially disenfranchised of focused oncological input due to having less robust care pathways established to date...

Any injury of a hand more or less disintegrates the injured hand. The rehabilitation of an alienated hand is prolonged. How can the alienation of the own but injured hand and the involuntary and unconscious inhibition of its perception and use be diagnosed, explained, avoided and designated? Medical observations and interviews with patients and therapists on the occasion of rehabilitation of hand injuries resulted in the development of a new concept of biopsychosocial integrating rehabilitation and a creative hand therapy with the objective of integrating injured and alienated hands...

Limb amputation is sometimes being performed in long-standing complex regional pain syndrome (CRPS), although little evidence is available guiding management decisions, including how CRPS recurrence should be managed. This report details the management of a young soldier with CRPS recurrence 2 years after midtibial amputation for CRPS. Conventional spinal cord stimulation did not achieve paraesthetic coverage, or pain relief in the stump, whereas L4 dorsal root ganglion stimulation achieved both coverage and initially modest pain relief, and over time, substantial pain relief...

BACKGROUND: Detailed pain mapping of extent and distribution in individuals with patellofemoral pain (PFP) within and around a complex structure such as the knee has yet to be explored. METHODS: Perceptions of on-going pain from adolescents and young adults (N = 35) with long-standing (>10 months) PFP were collected on high-resolution 3D digital body-schema of the knees. Location, area of pain, pain intensity, laterality, worse side of knee pain, symptom duration, and symmetry in bilateral knee pain were recorded...

Empathy is a complex psychological phenomenon crucial for social perception and interactions. Several lines of evidence suggest that the right temporo-parietal junction is involved in self-other control mechanisms that play an important role in empathic responses. However, limited direct evidence of the involvement of this region in empathic responses is currently available. In this study, inhibitory transcranial direct current stimulation over this region influenced empathic responses to others' pain. It was found that compared to participants that received anodal or sham transcranial direct current stimulation, participants who received cathodal transcranial direct current stimulation over the right temporo-parietal junction perceived the pain of others as less intense compared to sham stimulation and showed decreased late event related potentials to facial expressions of pain...

Uridine diphosphate-glucuronosyltransferase (UGT) 2B7, as one of significant drug enzymes, is responsible on the glucuronidation of abundant endobiotics or xenobiotics. We here report that it is markedly repressed in the tumor tissues of colorectal carcinoma (CRC) patients. Accordingly, morphine in CRC cells will stimulate the expression of its main metabolic enzyme, UGT2B7 during tolerance generation by activating the positive signals in histone 3, especially for trimethylated lysine 27 (H3K4Me3) and acetylated lysine 4 (H3K27Ac)...

OBJECTIVES: Complex Regional Pain Syndrome Type 1 is a severely disabling pain syndrome with no definite established treatment. We have performed a systematic literature review and meta-analysis of all randomized controlled trials to assess the benefit of bisphosphonates on pain and function in patients with Complex Regional Pain Syndrome Type 1. METHODS: A systematic literature search was performed in the Medline, Embase and Cochrane databases. Two authors selected independently blinded randomized trials comparing bisphosphonates to placebo on short-term (J30 to J40) and medium term pain (M2-M3), safety and function in patients with CRPS 1...

The term complex regional pain syndrome (CRPS) describes a variety of painful conditions, which typically occur distally on an extremity following an initiating event. Characteristically CRPS exceeds the expected clinical course in both magnitude and duration. Clinical manifestations of CRPS include sensory, vasomotor, sudomotor, motor and trophic disorders. The diagnosis of CRPS is purely clinical and based on the modified Budapest criteria. Essential differential diagnoses in the early phase include infections, neurological compression and inflammatory conditions...

Plastic changes in the CNS in response to peripheral sensory nerve injury are a series of complex processes, ranging from local circuit remodeling to somatotopic reorganization. However, the link between circuit remodeling and somatotopic reorganization remains unclear. We have previously reported that transection of the primary whisker sensory nerve causes the abnormal rewiring of lemniscal fibers (sensory afferents) on a neuron in the mouse whisker sensory thalamus (V2 VPM). In the present study, using transgenic mice whose lemniscal fibers originate from the whisker sensory principle trigeminal nucleus (PrV2) are specifically labeled, we identified that the transection induced retraction of PrV2-originating lemniscal fibers and invasion of those not originating from PrV2 in the V2 VPM...

We report an unusual case of adenocarcinoma of the lung metastasizing to the proximal phalanx of the third digit in a 56-year-old woman with overlying complex regional pain syndrome. The patient was initially treated for neuroma, fracture, and neuropathic pain with no improvement over a 4-month period before presenting to the emergency department for left third digit pain. Radiographic imaging showed substantial osteopenia and mottling; magnetic resonance imaging demonstrated an aggressive lesion to the proximal phalanx...

Fluoroquinolones are widely prescribed antibiotics, used for various infectious etiologies. These antibiotics carry the possibility of the serious adverse effect of peripheral neuropathy, with a true incidence not known owing to its rare existence. Recently, the Food and Drug Administration (FDA) has required alterations to drug labels to highlight this adverse effect of fluoroquinolones. This is a case report of a single patient at an inpatient neurology service at an urban academic medical center in the United States...

Peripheral neuropathic pain (PNP) and complex regional pain syndrome (CRPS) can be effectively treated with peripheral nerve stimulation. In this clinical trial report, effectiveness of novel, miniature, wirelessly controlled microstimulator of tibial nerve in PNP and CRPS was evaluated. In this pilot study the average preoperative visual analog scale (VAS) score in six patients was 7.5, with 1, 3 and 6 months: 2.6 (p=0.03), 1.6 (p=0.03), and 1.3 (p=0.02), respectively. The mean average score in the six patients a week preceding the baseline visit was 7...
