Background: Evidence is overwhelming for sex differences in pain, with women representing the majority of the chronic pain patient population. There is a need to explore novel avenues to elucidate this sex bias in the development of chronic inflammatory pain conditions. Complex regional pain syndrome (CRPS) is a chronic neuropathic pain disorder, and the incidence of CRPS is greater in women than in men by ~4:1. Since neurogenic inflammation is a key feature of CRPS, dysregulation of inflammatory responses can be a factor in predisposing women to chronic pain...

The degree and salience of pain have been known to be constantly monitored and modulated by the brain. In the case of maladaptive neural responses as reported in centralized pain conditions such as complex regional pain syndrome (CRPS), the perception of pain is amplified and remains elevated even without sustained peripheral pain inputs. Given that the attentional state of the brain greatly influences the perception and interpretation of pain, we investigated the role of the attention network and its dynamic interactions with other pain-related networks of the brain in CRPS...

RATIONALE: CRPS after a lumbar surgery has symptoms that are similar to PSSS. However, standard criteria for distinguishing CRPS from PSSS do not exist. We present a case report of a 31-year-old female with CRPS symptoms after lumbar spinal surgery treated by performing SELD. PATIENT CONCERNS: This patient was referred to our pain clinic for left ankle pain. She received a lumbar discectomy for a herniated lumbar disc (L5/S1) but the pain was aggravated after surgery...

Reflex sympathetic dystrophy is a subtype of complex regional pain syndrome, a condition characterized by persistent post-injury extremity pain. Temperature and sweating changes, edema, mobility changes, and a variety of hair, nail, and skin sequelae have been described. Only 23 articles published since 1990 describe dermatologic changes in CRPS. Given this paucity of literature, we present a case to further elucidate cutaneous manifestations of CRPS. Our patient is a 52-year-old Caucasian woman with a 19-year history of reflex sympathetic dystrophy who has presented with several dermatologic complaints...

BACKGROUND: Besides the classical clinical manifestations, body perception disturbances are common among patients with complex regional pain syndrome (CRPS). The Bath Body Perception Disturbance Scale (BBPDS) represents a useful tool to assess these changes in CRPS patients; however, to date no validated German version is available. OBJECTIVE: The aim of this study was to translate the BBPDS into German, to perform a cross-cultural adaptation and linguistic validation in patients with acute (symptoms <3 months) and stable (symptoms ≥3 months) CRPS...

Clinical evidence suggests vitamin C (Vit C) may protect against the development of complex regional pain syndrome (CRPS) after fracture and/or surgery. Tibia fracture followed by 4 weeks cast immobilization (fracture/cast) in rats results in nociceptive, vascular, and bone changes resembling clinical CRPS. In the present study, fracture/cast rats were treated with the oxidative stress inhibitors Vit C, N-acetyl cysteine (NAC) or 4-hydroxy-2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPOL) to examine their effects on CRPS-related nociceptive and vascular changes...

Metacarpal fractures constitute 7.8% of the upper extremity fractures. The common treatments remain nonsurgical procedure, but high-demanding patients or unstable fractures require fixation with Kirschner wire (K-wires), plate, and screws. However, these approaches may cause scarring and adhesion with poor functional results. From 2014 to 2015, the authors used an intramedullary headless screw to treat 25 patients (24 men, 1 woman) with metacarpal bones fractures (20 V, 3 IV, 1 III, and 1 II). The fractures patterns were 23 fractures of distal third of metacarpal bone (16 oblique, 5 comminute configurations, and 2 transverse), 1 fracture of the base of the II metacarpal bone...

STUDY DESIGN: Implementation paper. INTRODUCTION: Complex regional pain syndrome (CRPS) is relatively a common condition in the distal radius fracture (DRF) population with the effects resulting in many sufferers experiencing persistent pain and impairment 2 to 6 years after onset. Prevention is desirable as there is no known proven cure. PURPOSE OF THE STUDY: This study demonstrates how knowledge about CRPS and its prevention generated through iterative studies can be translated into practice in the workplace and how an interdisciplinary community of practice with therapists at the core can effect change...

INTRODUCTION: Intractable complex regional pain syndrome (CRPS)-related chronic foot pain, is a common therapeutic challenge for interventional pain management physicians and patients alike. Dorsal root ganglia (DRG) stimulation is a very target specific dorsal column stimulation technique with very promising clinical outcomes. Patients with CRPS foot pain and previous back surgery can benefit from DRG stimulation but also run a significant risk of epidural trauma from the DRG sheath advancement...

REVIEW
Frank Birklein, Alaa Ibrahim, Tanja Schlereth, Wade S Kingery
Distal limb fracture is the most common cause of complex regional pain syndrome (CRPS), thus the rodent tibia fracture model (TFM) was developed to study CRPS pathogenesis. This comprehensive review summarizes the published TFM research and compares these experimental results with the CRPS literature. The TFM generated spontaneous and evoked pain behaviors, inflammatory symptoms (edema, warmth) and trophic changes (skin thickening, osteoporosis) resembling symptoms in early CRPS. Neuropeptides, inflammatory cytokines, and nerve growth factor (NGF) have been linked to pain behaviors, inflammation, and trophic changes in the TFM model and proliferating keratinocytes were identified as the primary source of cutaneous cytokines and NGF...

A lumbar sympathetic ganglion block (LSB) is a therapeutic method for complex regional pain syndrome (CRPS) affecting the lower limbs. Recently, LSB with botulinum toxin type A and B was introduced as a novel method to achieve longer duration of analgesia. In this study, we compared the botulinum toxin type A (BTA) with botulinum toxin type B (BTB) in performing LSB on patients with CRPS. LSB was performed with either BTA or BTB on patients with CRPS in their lower extremities. The length of time taken for patients to return to the pre-LSB pain score and the adverse effect of LSB with BTA/BTB were investigated...

Aims: Complex regional pain syndrome (CRPS) is characterized by chronic debilitating pain disproportional to the inciting event and accompanied by motor, sensory, and autonomic disturbances. The pathophysiology of CRPS remains elusive. An exceptional case of severe CRPS leading to forearm amputation provided the opportunity to examine nerve histopathological features of the peripheral nerves. Methods: A 35-year-old female developed CRPS secondary to low voltage electrical injury. The CRPS was refractory to medical therapy and led to functional loss of the forelimb, repeated cutaneous wound infections leading to hospitalization...

The acute phase of complex regional pain syndrome (CRPS) is pathophysiologically characterized by an activation of the immune system and its associated inflammatory response. During the course of CRPS, central nervous symptoms like mechanical hyperalgesia, loss of sensation, and body perception disorders develop. Psychological factors such as pain-related anxiety and traumatic events might have a negative effect on the treatment outcome. While the visible inflammatory symptoms improve, the pain often persists...

BACKGROUND: Both dysfunctional neuropeptide signaling and immune system activation are characteristic of complex regional pain syndrome (CRPS). Unknown is whether substance P (SP) or calcitonin gene-related peptide (CGRP) support autoantibody production and, consequently, nociceptive sensitization. METHODS: These experiments involved the use of a well-characterized tibia fracture model of CRPS. Mice deficient in SP expression (Tac1-/- ) and CGRP signaling (RAMP1-/- ) were used to probe the neuropeptide dependence of post-fracture sensitization and antibody production...

Fluoroquinolones are a class of popular outpatient antimicrobial agents with a wide spectrum of therapeutic indications for respiratory and genitourinary infections. Though the most common side effects are gastrointestinal, fluoroquinolones have been increasingly associated with neurotoxicity including peripheral neuropathy and seizures. We present here a case of a 43-year-old woman with previously resolved type I complex regional pain syndrome (CRPS) who presented with symptoms of CRPS and neurotoxicity in the setting of levofloxacin administration...

Complex regional pain syndrome (CRPS) is a debilitating neurologic disorder with an interlinked and yet incompletely defined pathogenesis. Treatment options remain a therapeutic challenge. Linagliptin is one of the dipeptidyl peptidase-4 (DPP-4) inhibitors which are used for the treatment of diabetes mellitus. Apart from the improvement of glycemic control, accumulating evidence points to the beneficial effects of DPP-4 inhibitors in a wide array of conditions. Herein, the present study was outlined to investigate the antinociceptive effect of linagliptin in acute pain conditions, and in an animal model of CRPS...

BACKGROUND: Chronic pelvic pain (CPP) represents a group of poorly understood disorders that are often refractory to conventional treatment. Referral to pain management typically occurs later in the continuum of care; as such, many of the injections and nerve blocks commonly prescribed for such patients are potentially limited in efficacy. While neuromodulation is conventionally considered the next algorithmic step in the treatment of chronic pain after injections fail, there is a common perception that neuromodulation is largely ineffective for CPP conditions...
