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.

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.

Neuropathic pain is a frequent consequence of cancer pain. Quite often, in the end stage, it is difficult to discern its presence and delineate its characteristics in the context of painful cancer complications. The aim of this study was to compare the diagnostic accuracy of the Douleur Neuropathique en 4 Questions (DN4) and painDETECT questionnaires, which were translated to the patient's native language, for the diagnosis of peripheral neuropathic pain in oncology patients. ⋯ At standard cutoff values, the DN4 and painDETECT questionnaires, despite having been translated to the patient's native language, failed to adequately discriminate between neuropathic and non-neuropathic pain in our end-stage cancer patients.

The aim of the study was to evaluate the effectiveness of greater occipital nerve decompression for the management of occipital neuralgia. Eleven patients of medical refractory occipital neuralgia were enrolled in the study. Local anaesthetic blocks were used for confirming diagnosis. ⋯ Only 2 patients failed to notice any significant improvement. The mean follow-up period was 12.45 ± 1.29 months. Surgical decompression of greater occipital nerve is a simple and viable treatment modality for the management of occipital neuralgia.

Quantitative sensory testing after macroreplantation: evidence for a specific somatosensory profile.
A comprehensive functional recovery is one of the criteria for successful replantation of an amputated limb. Functionality of a replanted limb is strongly dependent on its regained sensibility. In previous studies concerning the sensibility of replanted limbs, only a few somatosensory submodalities were examined in small samples. ⋯ This distinct profile of impaired somatosensation shares some features of the somatosensory profile of neuropathic pain syndromes. Patients' limbs that were replanted many years before the present quantitative sensory testing showed more sensory deficits than patients with more recent replantations. This knowledge might be helpful in the development of more specific and more successful rehabilitation programs with replanted patients and improves the behavioral function of the replanted limb.
