Lidocaine infusion for the treatment of complex regional pain syndrome: Case series and literature review.

Introduction: Complex regional pain syndrome (CRPS) is a chronic pain condition most often triggered by direct injury to an extremity that is characterized by disproportionate pain, sensory abnormalities, and autonomic dysfunction. Early research into intravenous lidocaine therapy for CRPS has demonstrated promise, but clinical evidence remains scarce. We report on 12 patients with chronic CRPS who underwent intravenous lidocaine therapy and discuss our findings in the context of the existing literature.

A conceptual model for assessing the risk of unidentified pain.

Untreated or undertreated pain is well established as a significant problem, but unidentified pain is a distinct construct that still needs to be clearly modeled or fully described. This paper aims to develop a conceptual model of unidentified pain in humans with the goal of future development of an unidentified pain risk tool. A multi-phase process was employed consisting sequentially of 1) brainstorming followed by consensus building, 2) peer-review and publication of an integrative theoretical review protocol for "unidentified pain," 3) conduct of the integrative review, and 4) a repeated brainstorming session to identify areas of risk for unidentified pain to produce a conceptual model.

Effects of mirror therapy in post-traumatic complex regional pain syndrome type-1: a randomized controlled study.

Objective: To investigate the effects of mirror therapy applied in addition to routine rehabilitation on clinical outcomes in post-traumatic complex regional pain syndrome type 1.

Design: Single-blind randomized controlled trial.

Subjects: Patients with trauma-induced complex regional pain syndrome type 1 of the hand receiving outpatient rehabilitation.

Efficacy of N-acetylcysteine in reducing inflammation and oxidative stress to prevent complex regional pain syndrome type 1.

This study aimed to evaluate the effectiveness of N-acetylcysteine (NAC) in preventing complex regional pain syndrome type 1 (CRPS-1) by reducing proinflammatory cytokines and oxidative stress markers in patients with distal radius fractures. A retrospective single-center study at Bursa City Hospital involves patients over 50 years of age with distal radius fractures treated between January 2021 and December 2023. A total of 60 patients (mean age, 62.

Effects of Mecobalamin on the Functional Outcomes of Complex Regional Pain Syndrome Type 1 of the Foot and Ankle.

Background: Because of the unclear pathophysiology and the lack of consensus on the gold standard treatment of complex regional pain syndrome (CRPS), management requires a multidisciplinary approach, with the use of various treatment modalities. Nonetheless, no studies have ever been conducted to uncover the potential of mecobalamin as a treatment for CRPS type 1. Hence, the aim of this clinical trial was to evaluate the effects of mecobalamin on the functional outcomes of patients with CRPS type 1 of the foot and ankle, the total amount of pregabalin ingested, and the duration of pregabalin use in each patient.

Adenosine triphosphate: a new player in complex regional pain syndrome type 1.

The complex regional pain syndrome type 1 (CRPS-1) is one of the most discussed painful syndromes due to the variability and severity of its symptoms. CRPS-1 generally occurs after a trauma, a fracture or a sprain followed by an immobilization. Classical diagnostic criteria are not always clear; hence, the diagnosis is difficult.

Does Platelet-Rich Plasma Deserve a Role in Accelerating the Recovery of Reflex Sympathetic Dystrophy Following Distal Radius Fracture?

Introduction: This study was to evaluate the efficacy of multiple platelet-rich plasma injections in reflex sympathetic dystrophy following distal radius fracture after previous various treatments have failed.

Materials And Methods: This comparative prospective study was designed for 64 patients of reflex sympathetic dystrophy developed following distal radius fracture, from January 2009 to December 2020 were enrolled in this study. This cohort of patient was given either four multiple subcutaneous platelet-rich plasma injections at weekly interval ( = 32) or two injections in a month with 15 days interval ( = 32).

Mechanisms of complex regional pain syndrome.

Complex Regional Pain Syndrome (CRPS) is a chronic pain disorder characterized by a diverse array of symptoms, including pain that is disproportionate to the initial triggering event, accompanied by autonomic, sensory, motor, and sudomotor disturbances. The primary pathology of both types of CRPS (Type I, also known as reflex sympathetic dystrophy, RSD; Type II, also known as causalgia) is featured by allodynia, edema, changes in skin color and temperature, and dystrophy, predominantly affecting extremities. Recent studies started to unravel the complex pathogenic mechanisms of CRPS, particularly from an autoimmune and neuroimmune interaction perspective.

Letter to the editor 'Prednisolone 20 mg vs. 40 mg in complex regional pain syndrome type I: An imperative consideration'.

Corticosteroids are a potential treatment to combat Complex Regional Pain Syndrome, however the adverse effect profile far outweighs the benefits of using them. Avascular necrosis and Osteonecrosis are among well defined adverse effects. Postmenopausal women are especially affected by corticosteroids due to loss of estrogen.

Complex regional pain syndrome: advances in epidemiology, pathophysiology, diagnosis, and treatment.

Complex regional pain syndrome (CRPS) is a rare pain disorder that usually occurs in a limb after trauma. The features of this disorder include severe pain and sensory, autonomic, motor, and trophic abnormalities. Research from the past decade has offered new insights into CRPS epidemiology, pathophysiology, diagnosis, and treatment.

Complex regional pain syndrome: diagnostic challenges and favorable response to prednisolone.

Complex regional pain syndrome (CRPS), characterized by severe and disproportionate pain, is a rare and debilitating condition. Due to its rarity, evidence-based treatment guidelines remain limited, creating a challenge for clinicians. We present the case of a 20-year-old female with CRPS type 1 of the right hand.

Catheter Tip-Associated Mass With Continuous Infusion of Sufentanil for Persistent Spinal Pain Syndrome Type 2: A Case Report Including Histopathologic Examination and Review of the Associated Basic and Clinical Research.

Objectives: Intrathecal opioids delivered by implanted pumps are used to treat malignant or nonmalignant chronic pain. In this study, we 1) review a case in which intrathecal infusions of sufentanil along with other adjuvants were used and after an extended period led to an intrathecal mass and 2) compared and contrasted the potential mechanisms for these phenomena.

Materials And Methods: A woman aged 66 years with a history of scoliosis and multiple spine surgeries was treated with an implantable drug delivery system for treating persistent pain after laminectomy.

Delay in Time to Diagnosis of Idiopathic Transient Osteoporosis of the Hip with Radiographs: Diagnostic Insights from a Series of 10 Cases.

Introduction: Transient osteoporosis of the hip (TOH) is a poorly recognized self-limiting clinical entity. Due to a lack of awareness among the clinicians, the condition is often misdiagnosed leading to inappropriate treatment, thereby lengthening the time to diagnosis (TTD). In this study, we analyze the delay in TTD of TOH using plain radiographs and present the optimal management strategy.

Open Reduction and Plate Fixation, External Fixator, and Conservative Treatment for Intra-articular Distal Radius Fractures.

Background Distal radius fractures are common fractures. Treatment of intra-articular fractures is controversial, with treatment modalities including closed reduction and casting, open reduction and plating, and closed reduction and fixation with an external fixator. In this study, we compared the clinical and radiological outcomes of our patients treated with three different methods for intra-articular distal radius fractures.
