The management of neuropathic pain and pain related to bone vaso-occlusive crises in sickle cell disease remains challenging in children. Lidocaine 5% patches are recommended in adults for neuropathic pain treatment, but they are not recommended in children. The purpose of this study was to assess the efficacy and tolerance of lidocaine 5% patches in pediatric inpatients. ⋯ Although lidocaine 5% patches decreased the pain's intensity in nearly half of the enrolled patients with an excellent tolerance, the efficacy endpoint was not reached. Further studies should consider a more refined selection of the experimental population to assess the efficacy of lidocaine 5% patches in the pediatric population.

Low back-related leg pain with nerve root involvement is conceptually regarded as a neuropathic condition. However, it is uncertain to what extent patients with this condition can be formally classified with neuropathic pain. ⋯ The painDETECT Questionnaire performed poorly at detecting neuropathic pain among patients with low back-related leg pain, compared to clinical examination based on the 2016 NeuPSIG grading system as a reference standard. Our results do not support the use of painDETECT as a screening tool to classify or grade neuropathic components in this population.

Randomized Controlled Trial
Thermal Versus Super Voltage Pulsed Radiofrequency of Stellate Ganglion in Post-Mastectomy Neuropathic Pain Syndrome: A Prospective Randomized Trial.
Breast cancer is the second most common cancer world-wide following lung cancer. Post-mastectomy pain syndrome (PMPS) is one of the chronic post-surgical pain disorders (CPSP) of neuropathic character; nearly 20-50% of patients may develop PMPS. Stellate ganglion blockade has been performed as a diagnostic, prognostic, or therapeutic intervention for different pain syndromes. ⋯ Cancer breast, post mastectomy pain syndrome, stellate ganglion block, radiofrequency therapy.

Dorsal root ganglion stimulation (DRGS) treats discrete, localized areas of neuropathic pain. But there are no long-term results available so far. ⋯ Knee pain, foot pain, hand pain, groin pain, neuromodulation, dorsal root ganglion stimulation, chronic neuropathic pain, paresthesia mapping.

Hyperalgesia and allodynia are typical signs of neuropathic pain. Quantitative sensory testing (QST) is a validated tool to clinically assess these phenomena. However, whether QST reveals findings that are reported by the patients is unclear. The aim of this study was therefore to investigate the association between self-reported symptoms assessed with the painDETECT questionnaire (PDQ) with results of validated QST. ⋯ Results demonstrate that self-reported PDQ symptoms cannot predict abnormal QST values. The poor predictive power of the PDQ may depend on several factors based on possibility of comparison between PDQ and QST and also on methodical issues. Both, symptoms (questionnaires) and signs address complementary aspects of the pain experience and should be considered for diagnosis and treatment of neuropathic pain.
