Physiotherapy for pain and disability in adults with complex regional pain syndrome (CRPS) types I and II.

Cochrane Database Syst Rev 2022 05 17;5:CD010853. Epub 2022 May 17.

Department of Health Sciences, Centre for Health and Wellbeing Across the Lifecourse, Brunel University London, Uxbridge, UK.

Background: Complex regional pain syndrome (CRPS) is a painful and disabling condition that usually manifests in response to trauma or surgery and is associated with significant pain and disability. CRPS can be classified into two types: type I (CRPS I) in which a specific nerve lesion has not been identified and type II (CRPS II) where there is an identifiable nerve lesion. Guidelines recommend the inclusion of a variety of physiotherapy interventions as part of the multimodal treatment of people with CRPS. Read More

Bispecific mAb Antibodies Targeting CD59 Enhance the Complement-Dependent Cytotoxicity Mediated by Rituximab.

Int J Mol Sci 2022 May 6;23(9). Epub 2022 May 6.

Christian Doppler Laboratory for Innovative Immunotherapeutics, Institute of Molecular Biotechnology, Department of Biotechnology, University of Natural Resources and Life Sciences, Vienna (BOKU), Muthgasse 18, 1190 Vienna, Austria.

Inhibition of complement activation via the overexpression of complement-regulatory proteins (CRPs), most notably CD46, CD55 and CD59, is an efficient mechanism of disguise of cancer cells from a host immune system. This phenomenon extends to counteract the potency of therapeutic antibodies that could lyse target cells by eliciting complement cascade. The manifold functions and ubiquitous expression of CRPs preclude their systemic specific inhibition. Read More

Aspects of the Complement System in New Era of Xenotransplantation.

Front Immunol 2022 14;13:860165. Epub 2022 Apr 14.

Department of Pediatric Surgery, Osaka University Graduate School of Medicine, Osaka, Japan.

After producing triple (Gal, H-D and Sd)-KO pigs, hyperacute rejection appeared to no longer be a problem. However, the origin of xeno-rejection continues to be a controversial topic, including small amounts of antibodies and subsequent activation of the graft endothelium, the complement recognition system and the coagulation systems. The complement is activated via the classical pathway by non-Gal/H-D/Sda antigens and by ischemia-reperfusion injury (IRI), via the alternative pathway, especially on islets, and via the lectin pathway.

Altered basal ganglia infraslow oscillation and resting functional connectivity in complex regional pain syndrome.

J Neurosci Res 2022 Jul 20;100(7):1487-1505. Epub 2022 Apr 20.

School of Medical Sciences and Brain and Mind Centre, University of Sydney, Camperdown, New South Wales, Australia.

Complex regional pain syndrome (CRPS) is a painful condition commonly accompanied by movement disturbances and often affects the upper limbs. The basal ganglia motor loop is central to movement, however, non-motor basal ganglia loops are involved in pain, sensory integration, visual processing, cognition, and emotion. Systematic evaluation of each basal ganglia functional loop and its relation to motor and non-motor disturbances in CRPS has not been investigated. Read More

Perineural Adductor Canal Catheter Placement for Prevention of Complex Regional Pain Syndrome-I Exacerbation After Knee Arthroscopy: A Case Report.

A A Pract 2022 Apr 11;16(4):e01579. Epub 2022 Apr 11.

From the Department of Anesthesiology and Pain Medicine, University of California, Davis Medical Center, Sacramento, California.

Arthroscopic knee surgery is a common trigger for lower extremity complex regional pain syndrome (CRPS). Few studies assess nerve block catheters for CRPS treatment; they do not appear to be studies of regional anesthesia to treat CRPS that occurs after knee surgery. We present a case of CRPS-I triggered by knee surgery on multiple prior occasions but finally prevented by perineural adductor canal catheter placement. Read More

Perceptual anomalies can provide insights into underlying pathologies even when they are not the main symptom of many clinical conditions. Complex regional pain syndrome (CRPS) and fibromyalgia are chronic pain conditions associated with changes in the central nervous system, possibly leading to enhanced visual sensitivity. It is unclear whether this occurs more than for people with other types of pain. Read More

Department of Physiology, Showa University School of Medicine, Shinagawa, Japan.

Complex regional pain syndrome (CRPS) is a chronic pain syndrome that occurs in tissue injuries as the result of surgery, trauma, or ischemia. The clinical features of this severely painful condition include redness and swelling of the affected skin. Intriguingly, it was recently suggested that transient receptor potential ankyrin 1 (TRPA1) is involved in chronic post-ischemia pain, a CRPS model. Read More

Effectiveness of perampanel in managing chronic pain caused by the complex regional pain syndrome: A case report.

Medicine (Baltimore) 2021 Dec;100(48):e27791

Department of Physical Medicine and Rehabilitation, Ulsan University Hospital, University of Ulsan College of Medicine, Ulsan, Republic of Korea.

Rationale: The α-amino-3-hydroxy-5-methy-4-isoxazole propionate (AMPA) receptor plays a critical role in the development and persistence of pain, and AMPA receptor antagonists are considered possible therapeutic targets for controlling pain. This report describes a patient with complex regional pain syndrome (CRPS) type I in the right lower leg and foot who responded well to perampanel, an AMPA receptor antagonist, for managing the chronic pain.

Patient Concern: A 61-year-old woman complained of pain in her right lower leg and foot over a period of 7 year (numeric rating scale: 8) due to CRPS type I. Read More
