Complex regional pain syndrome type 1 (CRPS-1) is a condition that affects adolescents and children under the age of 7. It usually follows minor injury and rarely occurs spontaneously. The pain is usually out of proportion to the inciting injury. Pain, allodynia, and/or hyperalgesia are severe enough to inhibit use of the affected limb. Delay in diagnosis and self and/or iatrogenic immobilization of the affected limb may lead to worsening pain, skin hypersensitivity and discoloration, swelling, and vasomotor and dystrophic abnormalities. The diagnosis of CRPS-1 and 2 is based on symptoms. There are no diagnostic tests that can confirm the presence or absence of CRPS-1. CRPS-2 diagnosis is established by nerve conduction test and electromyography. Clinical practice neuropathic guidelines are most effective for CRPS-2 treatment. Pharmacological and interventional treatment options for CRPS-1 are limited and usually ineffective because the underlying mechanism(s) are yet to be determined.

Abstract From the previous issue, this article continues a discussion of the potentially confusing aspects of the diagnostic formulation for complex regional pain syndrome type 1 (CRPS-1) proposed by the International Association for the Study of Pain (IASP), the relevance of these issues for a proposed future protocol, and recommendations for clinical practice. IASP is working to resolve the contradictions in its approach to CRPS-1 diagnosis, but it continues to include the following criterion: “[c]ontinuing pain, which is disproportionate to any inciting event.” This language only perpetuates existing issues with current definitions, specifically the overlap between the IASP criteria for CRPS-1 and somatoform disorders, overlap with the guidelines for malingering, and self-contradiction with respect to the suggestion of injury-relatedness. The authors propose to overcome the last of these by revising the criterion: “[c]omplaints of pain in the absence of any identifiable injury that could credibly account for the complaints.” Similarly, the overlap with somatoform disorders could be reworded: “The possibility of a somatoform disorder has been thoroughly assessed, with the results of that assessment failing to produce any consistencies with a somatoform scenario.” The overlap with malingering could be addressed in this manner: “The possibility of malingering has been thoroughly assessed, with the results of that assessment failing to produce any consistencies with a malingering scenario.” The article concludes with six recommendations, and a sidebar discusses rating impairment for CRPS-1 (with explicit instructions not to use the pain chapter for this purpose).

Case report on 14 years old girl with type 1 complex regional pain syndrome (CRPS) is presented. At first admission in 5.5 months after right hand injury and development of type 1 CRPS, paravasal sympathectomy on the right upper extremity was performed. Complete elimination of pain syndrome and restoration of the extremity function was achieved. Five and a half months after discharge the left foot and in 3 weeks later the right hand were injured. In both cases injuries were accompanied by pronounced CRPS clinical picture. At second admission in 6 weeks after foot injury interventional treatment with placement of catheters next to nerve trunks and bolus administration of antibiotics was performed for 1 week and enabled to achieve remission of the disease. It was noted that not only hypersymphaticotony but also psychological status of a patient were important for the disease development.
