RESUMO
OBJECTIVE: Complex regional pain syndromes (CRPS) involve neuropathic limb pain and localized circulatory abnormalities. The authors hypothesized that (1) pediatric CRPS patients exhibit systemic autonomic symptoms and orthostatic and/or cardiac sympatho-vagal dysregulation and (2) their orthostatic regulation differs from healthy controls and pediatric patients with postural orthostatic tachycardia syndrome (POTS). METHODS: CRPS children and adolescents (n=20) underwent a 6-week trial of physical therapy and cognitive-behavioral treatment. Measures included pain and function scores, regional and systemic autonomic symptom profiles, heart rate and blood pressure with tilt, heart rate variability indices, and baroreflex gain. Systemic autonomic symptoms were recorded in 55 healthy pediatric controls. Tilt responses in CRPS patients were compared with those of 21 POTS patients and 39 healthy controls. RESULTS: CRPS patients' regional autonomic symptoms, pain, and limb function improved over 6 weeks (P<0.01). At baseline CRPS patients reported more systemic autonomic symptoms than controls (P<0.05). Tilt table test showed orthostatic stability, but the mean heart rate increase with tilt was greater in CRPS patients than controls (P<0.001). POTS patients showed significant increases with tilt in mean heart rate and diastolic and systolic blood pressures compared with controls (P<0.001). There were significant increases in the mean systolic and diastolic blood pressures in POTS compared with CRPS patients but no difference in the mean heart rate between groups. DISCUSSION: CRPS patients reported multiple regional and systemic autonomic symptoms that improved during the study course, and they experienced minimal and transient tilt table-induced hemodynamic changes compared with POTS patients but relatively similar to controls.

The introduction of clean intermittent catheterization (CIC) in 1972 and low-dose chemoprophylaxis (LDCP, antibiotic prophylaxis), anticholinergic medication and urological surgery in the mid-1980s has improved the long-term outcome of renal function in children with neurogenic bladder sphincter dysfunction (NBSD) due to spina bifida (SB). We have conducted a European survey of the protocols for diagnosing and treating urinary tract infections (UTIs) in these children, using a web-based questionnaire. The responses from 41 centers in 14 European countries confirm that although most centers have standardized protocols for treating UTIs, there is no consensus among European centers in terms of protocols for preventing, diagnosing and treating UTIs in children with NBSD and for CIC.
