Gabapentin is effective in improving analgesia in patients with neuropathic cancer pain already treated with opioids.

The TSK was successfully translated into Italian, showing a good factorial structure and psychometric properties, and replicating the results of existing English versions of the questionnaire. Its use is recommended for research purposes.

Osteoarthritis (OA) is a leading cause of disability among older adults worldwide. Treatment aims are to alleviate inflammatory pain and improve physical function through non-pharmacological and pharmacological interventions. Non-steroidal anti-inflammatory drugs (NSAIDs) are recommended as first-line therapy. However, selection is challenged by patient age, comorbidities and polypharmacy, and by the drug's benefit/risk balance, all of which together influence the risk of cardiovascular (CV), gastrointestinal (GI) and renal adverse events (AEs). While the efficacy profile of the various NSAIDs is delineated, the differences in their safety profile are not straightforward. This narrative review provides practical indications by a multidisciplinary Italian expert panel for general practitioners and specialists managing OA patients with

Bonezzi C, Demartini L. Treatment options in postherpetic neuralgia. Acta Neurol Scand 1999: Suppl. 173: 25-35. Postherpetic neuralgia (PHN) is a separate disease entity that represents a complication of acute herpes zoster. PHN, involving aberrant somatosensory processing in the peripheral and/or central nervous system, is considered to be a chronic neuropathic pain, frequently unresponsive to all treatment modalities. Despite the clinical trial data demonstrating successful pain relief with several drug regimens, the pharmacologic management of neuropathic pain is difficult, particularly in PHN. Response to therapy is generally inhomogeneous. Some patients experience longterm pain control with either topical or oral monotherapy with antidepressants, anticonvulsants, or opioids. Other PHN patients, such as those suffering pain due to central nervous system lesions, are extraordinarily refractory to all measures. This article will review current treatmentstricyclic antidepressants, anticonvulsants, local anesthetics, clonidine, N-methyl+-aspartate (NMDA)-antagonists, and opioidsand focus on mechanism-based pharmacologic interventions. Pharmacologic approaches can be classified into three groups: 1) drugs that act topically in the affected skin area; 2) drugs that act on nerve excitability and conduction in sensory axons; and 3) drugs that act on neural damage-related synaptic changes. This last group is the only pain treatment option related to central denervation. To date, the treatment of PHN has relied on the use of tricyclic antidepressants (TCAs), which represent the most comprehensively studied medications for this pain syndrome. Clinical data indicate that TCAs are effective analgesics in approximately 50% of patients; these drugs have been recommended as first-line agents for all neuropathic pain syndromes except trigeminal neuralgia, but are frequently contraindicated or poorly tolerated in elderly patients with PHN. If monotherapy fails, a mechanism-and/or symptom-based multidrug regimen can be used. There is also consistent support for intravenous and topical lidocaine, intravenous ketamine, carbamazepine, and opioids. Gabapentin, a new anticonvulsant, can be considered a first-line oral medication for PHN based on the efficacy and safety results of a recently completed double-blind trial. In addition to positive effects on PHN, sleep, mood, and overall quality of life were significantly improved. neuralgia

The authors hypothesize that this antidromic activation could represent a possible antalgic mechanism of SCS in patients with peripheral neuropathic pain, but further neurophysiological studies will be needed to elucidate this hypothesis.
