We are reporting a case of child diagnosed with CRPS and successfully treated with supraclavicular brachial plexus catheter infusion of local anesthetic. Case Report: An eight-year-old male underwent a left thoracotomy, repair of esophageal vascular ring, and translocation of the left subclavian to the left carotid artery. Post-operative course was relevant for severe intractable left shoulder and left arm pain associated with allodynia and hyperalgesia. A supraclavicular catheter was inserted, and an infusion of ropivacaine 0.2% was started. The child was sent for physical therapy as he gradually regained all functions of his left arm and resumed his regular activities. Conclusion: Continuous supraclavicular brachial plexus catheter infusion of local anesthetic is a valuable method of reducing pain in severe cases of upper extremity pediatric CRPS and may be safer and more effective than other invasive measures such as sympathetic blocks and epidural catheterization. Further research surrounding the diagnosis and treatment of pediatric CRPS is needed to allow early diagnosis and treatment and to improve outcome.展开更多

Therefore, we aimed to identify the factors associated with psychopathology in adolescents with CRPS ahead of military service.Methods: We retrospectively reviewed all conscription examinees who had completed a Military Personality Inventory(MPI) during a period between February 2013 and December 2016. A total of 63 persons with a history of CRPS(19-years of age for all) were enrolled. Basic demographic and pain-related data were analyzed to examine their association with MPI results. The mean FGR score as well as the 8 subdomain scores were compared between those with pain duration at <15 months(n=30) vs. ≥15 months(n=33). Binary MPI results(normal-abnormal) were also compared between the two groups.Results: In multivariate analysis, abnormal MPI was associated with pain duration, with an odds ratio(OR) at 1.05 for every 1-month increase [95% confidence interval(CI) 1.02–1.08;P=0.002]. Subjects with pain duration at ≥15 months have lower faking good response score(P<0.001 vs. those with pain duration at <15 months), and higher abnormal MPI result rate, faking bad response, inconsistency, anxiety, depression, somatization, paranoid, personality disorder cluster A, and personality disorder cluster B scores(P<0.05). Pain duration was significantly associated with the MPI variables.Conclusions: Pain duration is associated with psychopathology in adolescents with CRPS. Psychopathologic features increased as the disease duration increased. A comprehensive understanding of time-dependent psychopathological factors could support the planning of multimodal approaches for managing adolescent CRPS.展开更多

MAP was cultured from the blood of three members affected by the first five diseases and there was accompanying elevated anti-MAP Ig G in two members. The patient affected by the sixth disease has a markedly elevated anti-MAP titer. The two patients affected by the first four diseases have been treated with a combination of anti-MAP antibiotics and ultraviolet blood irradiation therapy with resolution of the disease symptomatology and inability to culture MAP in post treatment blood samples. These case reports of patients with MAP infections provide supportive evidence of a pathogenic role of MAP in humans.展开更多

Beliefs about what is important for the management of patients with CRPS are lacking across all medical and allied health disciplines. Difficulties are no gold standard for diagnosis and evidence for intervention methods is moderate or can be conflicting. This paper explores what Physiotherapists believe to be important in a clinical setting for their management of CRPS, as well as documenting and evaluating their interventional methods used in everyday clinical practice across the region of the South Island of New Zealand. This has not been recorded before. Eighty-one Physiotherapists replied to questions on their usual treatment interventions for the management of CRPS, their frequency of use of these treatment interventions, and what they believed to be important in the management of pain and improvement of function. The results demonstrated that CRPS is not a common condition seen regularly by Physiotherapists;that there is a high level of variation between the physiotherapy interventions used and that Physiotherapists’ beliefs regarding interventions used for pain management and functional restoration differ. Education was reported as the most frequently used intervention method. Those physiotherapists seeing CRPS patients more frequently are more likely to use evidence based intervention methods like graded motor imagery or sensory motor training.展开更多

Patients with CRPS experience allodynia, hyperalgesia, autonomic dysfunction, movement difficulties and dystrophic changes. However other characteristics that may be unique to the pain in CRPS require further study. This study evaluated pain parameters in ninety five subjects composed of three groups: healthy pain free controls, patients with radiculopathy and CRPS patients. Healthy subjects were tested in all four extremities, whereas radiculopathy and CRPS patients were tested only on the most affected extremity. All subjects were tested for the following pain parameters: thermal allodynia, mechanical static and dynamic allodynia, windup, and a hyperalgesic mechanical stimulus. All subjects were also evaluated for autonomic dysfunction, movement disorder and dystrophic skin changes. Statistically significant differences were found between both pain groups and the healthy control subjects as well as between the two pain groups. The finding that statistically differentiated CRPS from radiculopathy and normal controls was pain spread following an algesic mechanical and cold stimulus as well as after sensations to these stimuli. The study demonstrated a simple bedside test that discriminated between CRPS, radiculopathy and healthy control subjects.展开更多

This was a case series of two patients who developed Complex Regional Pain Syndrome under circumstances when a double crush phenomenon could have occurred. Both initially had spinal stenosis and subsequent spinal surgery. Both later had crush injuries to a unilateral lower extremity, which progressed to CRPS. There is no documented correlation between double crush syndrome and CRPS;however, these cases raise awareness about a heightened propensity for CRPS in such patients, which will lead to earlier, accurate diagnosis and treatment.展开更多

Patients and Méthod: This has been a transversal study carried out over 22 years on files of CRPS infected patients and submitted to rheumatologic consultation in the National Hospital University of Cotonou. Results: 73 out of 17,342 patients examined (0.42%) were suffering from CRPS. Those 73 patients (40 women, 54.8% and 33 men, 45.2%) were in average 54.66 years old and enjoyed an average duration of evolution of 5.79 months. The trauma (41 cases, 56.1%), the stroke (19 cases, 25%), the diabetes (8 cases, 11.3), were the main risk factors that were observed. CRPS was preferably located at the shoulder-hand (34.2%), shoulder (28.8%), wrist-hand (16.4%) and knee (11%). Inflammatory pain was observed in 55 cases. The treatment was dominated by griseofulvina (41 cases, 56.1%), antiinflammatory drugs (38 cases, 52%), analgesic (20 cases, 27, 3%), joint injection by betamethasone (17 cases, 27%). Conclusion: CRPS is not rare in our country. The first risk factor remains the trauma in rheumatologic consultation in Cotonou.展开更多

It is most often caused by a fracture, soft-tissue injury or surgical procedure and is divided into Type I, in which no nerve lesion is identified (classic reflex sympathetic dystrophy), and Type II where a specific nerve has been damaged (causalgia). In addition to the peripheral manifestations, there are many internal medical complications whose etiology is often not appreciated. This article will examine how CRPS affects the systems of: cognition;constitutional, cardiac, and respiratory complications;systemic autonomic dysregulation;neurogenic edema;musculoskeletal, endocrine and dermatological manifestations;as well as urological and gastrointestinal function.展开更多

We treated a patient in whom swelling of the wrist recurred during treatment of CRPS and septic arthritis of the hand was induced by group G hemolytic streptococcus. There are case reports of tuberculous arthritis of the hand during treatment of CRPS;however, the causal relationship of wrist joint inflammation with CRPS is unclear. Careful follow-up is necessary for wrist joint inflammation if a patient with CRPS relapses with swelling of the wrist.展开更多

Although the pathophysiology of CRPS is not fully understood, it is recognised that inflammatory processes and autonomic dysfunction are involved. These processes are associated with peripheral and central sensitisation as well as changes in brain structure and function, and are reflected in the clinical presentation of CRPS. CRPS management requires an interdisciplinary team and requires the therapeutic approach to be individualised. With regard to pharmacological treatment, bisphosphonates, corticosteroids, ketamine and anticonvulsants have been demonstrated to be effective for CRPS management. Psychotherapy, including cognitive-behavioural therapy, has produced promising results but more studies are needed to confirm its efficacy. Among rehabilitation interventions, there is evidence of the efficacy of physiotherapy and occupational therapy in diminishing CRPS symptoms and achieving a higher level of functioning. In this regard, the rehabilitation modality that seems the most promising according to the actual literature is graded motor imagery, which can help to reverse the maladaptive neuroplasticity occurring in CRPS.展开更多

She received HPV vaccination at the age of 15 years and three years later, she developed intermittent arthralgia, meralgia, and numbness in limbs. There were no orthostatic dysregulation symptoms. She had hypertelorism, and brachydactyly in both the hands, and revealed mild cubitus varus deformity with lateral instability. X-ray examination disclosed hypoplasia of the humeral capitellum and trochlea in elbow joints. G-banded chromosomes were shown to be composed of 48, XXXX. She was, therefore, diagnosed with XXXX syndrome, which explained the reason for her limb symptoms. Although some girls with HPV vaccination complain of various symptoms including limb pain and numbness, exact underlying cause of these symptoms needs to be ascertained carefully for reaching a final diagnosis.展开更多

CRPS is a multifactorial disease associated with disabling pain as well as sensory and motor deficits. The optimal therapeutic management is based on personalized multimodal treatment approaches;however, hirudotherapy has not been described in the available literature. To date, we have completed five medicinal leech treatments. Altogether, hirudotherapy led to rapid and substantial relief of symptoms, especially with respect to pain intensity ratings and skin temperature asymmetries. In addition, the patient’s active and passive agility of the affected limb improved obviously.展开更多

All patients had complete clinical data sets and accounted for 45.5% of the inpatients because of stroke. Results showed that the number of patients with hemiplegic shoulder pain post stroke increased yearly, attacking mainly males 50-69 years of age. Of 106 patients, there were 60 cases （56.6%） of adhesive capsulitis, 19 （17.9%） of shoulder subluxation, 14 （13.2%） of complex regional pain syndrome, and 13 （12.6%） of central pain. The main symptoms were shoulder pain （100%）, limit of shoulder mobility （98.1%）, and adhesion of the scapula （56.6%）. MRI of the shoulder showed tendon and ligament lesions （57.1%） and rotator cuff tear （38.1%）. 53.8% of central pain was related to the thalamus, in addition to the basal ganglia, brain stem, and cerebellopontine angle. Shoulder pain, upper limb motor function, and function independence were significantly improved after comprehensive rehabilitation. In par- ticular, electroacupuncture based on basic physical therapy exhibited efficacy on shoulder subluxa- tion and complex regional pain syndrome. Multiple linear regression results showed a negative re- lationship of efficacy of pain management with the attack period of shoulder pain, involvement of the posterior limb of the internal capsule, and duration between onset and rehabilitation treatment, but a positive correlation with pain-related education, pain regression period, and pain diagnosis.展开更多

文摘On the South Island of New Zealand, Anaesthetists and other Medical Professionals, frequently refer their patients with Complex Regional Pain Syndrome (CRPS) for physiotherapy management. Beliefs about what is important for the management of patients with CRPS are lacking across all medical and allied health disciplines. Difficulties are no gold standard for diagnosis and evidence for intervention methods is moderate or can be conflicting. This paper explores what Physiotherapists believe to be important in a clinical setting for their management of CRPS, as well as documenting and evaluating their interventional methods used in everyday clinical practice across the region of the South Island of New Zealand.

In this regard, the rehabilitation modality that seems the most promising according to the actual literature is graded motor imagery, which can help to reverse the maladaptive neuroplasticity occurring in CRPS.

文摘Physical exe rcise effectively alleviates chronic pain associated with complex regional pain syndrome type-Ⅰ.However,the mechanism of exe rcise-induced analgesia has not been clarified.Recent studies have shown that the specialized pro-resolving lipid mediator resolvin E1 promotes relief of pathologic pain by binding to chemerin receptor 23 in the nervous system.However,whether the resolvin E1-chemerin receptor 23 axis is involved in exercise-induced analgesia in complex regional pain syndrome type-Ⅰ has not been demonstrated.In the present study,a mouse model of chronic post-ischemia pain was established to mimic complex regional pain syndrome type-Ⅰ and subjected to an intervention involving swimming at different intensities.Chronic pain was reduced only in mice that engaged in high-intensity swimming.The resolvin E1-chemerin receptor 23 axis was clearly downregulated in the spinal cord of mice with chronic pain,while high-intensity swimming restored expression of resolvin E1 and chemerin receptor 23.Finally,shRNA-mediated silencing of chemerin receptor 23in the spinal cord reve rsed the analgesic effect of high-intensity swimming exercise on chronic post-ischemic pain and the anti-inflammato ry pola rization of microglia in the dorsal horn of the spinal cord.These findings suggest that high-intensity swimming can decrease chronic pain via the endogenous resolvin E1-chemerin receptor 23 axis in the spinal cord.
文摘A 19-year-old Japanese woman was referred to us with the complaints of arthralgia and meralgia following human papillomavirus (HPV) vaccination. She received HPV vaccination at the age of 15 years and three years later, she developed intermittent arthralgia, meralgia, and numbness in limbs. There were no orthostatic dysregulation symptoms. She had hypertelorism, and brachydactyly in both the hands, and revealed mild cubitus varus deformity with lateral instability. X-ray examination disclosed hypoplasia of the humeral capitellum and trochlea in elbow joints. G-banded chromosomes were shown to be composed of 48, XXXX. She was, therefore, diagnosed with XXXX syndrome, which explained the reason for her limb symptoms. Although some girls with HPV vaccination complain of various symptoms including limb pain and numbness, exact underlying cause of these symptoms needs to be ascertained carefully for reaching a final diagnosis.
文摘We report about hirudotherapy in a patient with chronic complex regional pain syndrome(CRPS) in the right hand. CRPS is a multifactorial disease associated with disabling pain as well as sensory and motor deficits. The optimal therapeutic management is based on personalized multimodal treatment approaches;however, hirudotherapy has not been described in the available literature. To date, we have completed five medicinal leech treatments. Altogether, hirudotherapy led to rapid and substantial relief of symptoms, especially with respect to pain intensity ratings and skin temperature asymmetries. In addition, the patient’s active and passive agility of the affected limb improved obviously.

文摘We selected 106 hemiplegic patients with shoulder pain hospitalized after stroke from three hospi- tals in Nanjing, China between February 2007 and January 2012. All patients had complete clinical data sets and accounted for 45.5% of the inpatients because of stroke. Results showed that the number of patients with hemiplegic shoulder pain post stroke increased yearly, attacking mainly males 50-69 years of age. Of 106 patients, there were 60 cases （56.6%） of adhesive capsulitis, 19 （17.9%） of shoulder subluxation, 14 （13.2%） of complex regional pain syndrome, and 13 （12.6%） of central pain. The main symptoms were shoulder pain （100%）, limit of shoulder mobility （98.1%）, and adhesion of the scapula （56.6%）. MRI of the shoulder showed tendon and ligament lesions （57.1%） and rotator cuff tear （38.1%）. 53.8% of central pain was related to the thalamus, in addition to the basal ganglia, brain stem, and cerebellopontine angle. Shoulder pain, upper limb motor function, and function independence were significantly improved after comprehensive rehabilitation. In par- ticular, electroacupuncture based on basic physical therapy exhibited efficacy on shoulder subluxa- tion and complex regional pain syndrome. Multiple linear regression results showed a negative re- lationship of efficacy of pain management with the attack period of shoulder pain, involvement of the posterior limb of the internal capsule, and duration between onset and rehabilitation treatment, but a positive correlation with pain-related education, pain regression period, and pain diagnosis.
文摘目的探讨局部注射维生素C方案预防复杂区域疼痛综合征(CRPS)的效果。方法80例接受桡骨远端骨折切开复位内固定患者,根据预防方案不同分为A组、B组、C组、D组,各20例。A组在缝合完毕后于骨折断端局部注射5 ml 0.9%生理盐水,B组局部注射125 mg维生素C+5 ml 0.9%生理盐水,C组局部注射250 mg维生素C+5 ml 0.9%生理盐水,D组局部注射500 mg维生素C+5 ml 0.9%生理盐水。比较四组CRPS发生率,干预前后的视觉模拟评分法(VAS)评分,疼痛缓解效果。结果A组CRPS发生率为50.00%,B组CRPS发生率为20.00%,C组CRPS发生率为0,D组CRPS发生率为0。B组、C组、D组CRPS发生率低于A组,C组、D组CRPS发生率低于B组,差异有统计学意义(P<0.05)。干预后,四组VAS评分均较干预前降低,且B组VAS评分(3.52±1.01)分、C组(3.21±1.22)分、D组(1.52±0.25)分低于A组的(4.25±1.07)分,D组低于B组、C组,差异有统计学意义(P<0.05)。干预后,B组、C组VAS评分比较差异无统计学意义(P>0.05)。A组疼痛缓解优良率为35.00%,B组为70.00%,C组为70.00%,D组为95.00%。B组、C组、D组疼痛缓解优良率高于A组,D组高于B组、C组,差异有统计学意义(P<0.05)。B组、C组的疼痛缓解优良率比较,差异无统计学意义(P>0.05)。结论对桡骨远端骨折切开复位内固定患者在切口缝合完毕后于骨折断端局部注射500 mg维生素C+5 ml 0.9%生理盐水能缓解患者疼痛程度,降低CRPS发生率,值得进一步在临床推广以及应用。
