Spinal cord stimulation (SCS) is a neuromodulation technique using electricity, proposed for the first time by Shealy in 1967, as an alternative to neuroablation. Technological improvements in the last 20 years (percutaneous electrodes, single and dual leads, octopolar electrodes, high energy internal pulse generators) have allowed to obtain good results with SCS in various clinical situations of chronic pain. The main clinical indications to SCS are: vascular pain--refractory angina and peripheral vascular diseases (PVD); rachidian pain--failed back surgery syndrome (FBSS), degenerative low back leg pain (LBLP), nerve root lesions, incomplete spine lesions, spinal stenosis; neuropathic pain; chronic regional pain syndrome (CRPS) type 1 and type 2; perineal pain and urological diseases (urge-incontinence, interstitial cystitis). ⋯ All of this is going to change the attitude towards SCS in USA, where the amputation incidence for critical ischaemia is considerably higher than in Europe. An indication to SCS not very mentioned in literature and that seems to have good results is LBLP due to acquired or mixed (constitutional-acquired) spinal stenosis. In this situation SCS seems to improve notably pain control and quality of life index of patients.

Managing pain effectively is one of the biggest challenges in medicine, let alone when dealing with the dying patient and his family. For palliative care specialists this is a daily challenge. However, ''To cure when possible, to give comfort always'' is an empty credo if physicians don't use every weapon in the medical arsenal to relieve the suffering caused by chronic pain. ⋯ Concerns regarding under treatment of chronic pain have captured the attention of patient advocacy groups, policy makers and scientific organisations. Misconceptions of opioid laws, negative social stigma and lack of valid prescribing alternatives to overcome this, together with paucity of formal provider education confound the issue. Much education needs to be done before opioids will be seen as a safe and reasonable treatment for chronic pain here in Italy.

ReviewOxycodone. Pharmacological profile and clinical data in chronic pain management.
Opioids are widely used as effective analgesic therapy for cancer pain. Despite years of controversy, their use has been also accepted in chronic non-cancer pain. Oxycodone alone and in combination has been used for over 80 years in the treatment of a variety of pain syndromes. ⋯ In cancer pain, oxycodone can be considered a valid alternative to oral morphine to be used for opioid rotation. No difference in analgesic efficacy between CR oxycodone and CR morphine was found. Controlled-release preparations, with a long duration of action, are attractive because they offer the advantage of longer dosing intervals and sustained analgesic effect.

Clinical TrialTransdermal buprenorphine combined with spinal morphine and naropine for pain relief in chronic peripheral vasculopathy.
of this study was to evaluate the effectiveness and the safety of the association of buprenorphine transdermal delivery system (TDS) (Transtec TDS) and peridural infusion of morphine and naropine, for the control of ischemic pain in patients suffering from peripheral arteriopathy. The administration of an opioid, pure agonist, as morphine, with a partial agonist opioid, as the buprenorphine, was used. Buprenorphine has shown a higher liposolubility in supraspinal districts, while the morphine acts above all on the mu receptor subtype of the spinal cord. ⋯ All parameters were evaluated daily for a period of 20+/-5 days. The results indicate that in group TTDS there was an improvement of pain symptomatology, also confirmed by the increased hours of sleep and the lower incidence of side effects. Instead in group NM, pain control was less effective, 18 patients needed a rescue dose of morphine, and the incidence of side effects increased.
