Electrical stimulation for the control of pain is now a well accepted therapeutic modality. Transcutaneous application of electrical stimulation is the most common technique employed and has been used to treat chronic pain, acute surgical pain, and acute pain of other origins. Percutaneous application of electricity to the nervous system through needles electrodes is useful in predicting the efficacy of implantable stimulators and has served the same function as diagnostic nerve block. Implantable stimulators have been used for stimulation of peripheral nerves, the anterior and posterior surfaces of the spinal cord, and the brain. Peripheral nerve stimulators are the most efficacious of the implantable devices. They are used specifically for pain of peripheral nerve injury origin. Their use for pain outside the distribution of the nerve stimulated is not yet proved.

Electrical stimulation is emerging as a new therapeutic and rehabilitative agent. Reviewed are pain control, restoration of lost functions and alteration of abnormal movement and other functions using electrical stimulation. Reported for acute and chronic pain control use are transcutaneous, dorsal column, spinal cord, peripheral nerve, and direct brain stimulation methods and results. Overall success ranges up to 50% for chronic pain problems and up to 80% for acute pain; e.g., postoperative incisional pain, sports medicine, and trauma. Restoration of lost function has broad implications for the future. These include phrenic nerve pacing for respiration, foot drop control, restoration of bladder function, and grasp control in the spinal cord-injured patient. Amelioration of abnormal function includes stimulation for epilepsy and cerebral palsy, certain symptoms of multiple sclerosis and scoliosis. The effects of electrostimulation are completely reversible and nondestructive. Technical details of devices and stimulus waveforms are also briefly considered.

In acute pain, TENS, ice packs, and a calm, reassuring attitude and voice are useful in reducing pain. Narcotic requirements can be reduced, and chronic pain may be prevented. Complications such as paralytic ileus and atelactasis can also be reduced. These techniques can be used in the emergency ward, the recovery room, and the doctor's office.

Acute pain from biliary colic is a model of pathological pain suitable for pharmacological investigations. It has been found useful for assaying analgesic effect of a narcotic-type agent (pentazocine) and a non-narcotic drug (indoprofen), both given intravenously in a single dose. Differences in pain intensity scores assessed on a five-point scale were taken as measurement of the pain-relieving effect. Distribution-free methods were used to estimate the potency ratio of the tested drugs. The analgesic potency of indoprofen based both on total and peak effect was roughly one-tenth that of pentazocine on a weight-for-weight basis. No adverse reactions were associated with indoprofen and a few were found after pentazocine.

Acute studies performed in five patients indicate that electrical stimulation of the brain could be a powerful tool for the reduction or control of intractable pain. While chronic or spontaneous pain could be relieved by stimulation of the periaqueductal gray matter, the accompanying side effects render it impossible to stimulate this site regularly. On the other hand, stimulation of medial thalamic sites, particularly medial to the nucleus parafascicularis, yielded good relief of chronic pain at parameters which did not cause many undesirable side effects. The same parameters also produced inhibition of acute pain in two of the five patients.

Relief of acute pain after surgery or trauma is still inadequate in many centres, most patients being treated with intermittent intramuscular injections of narcotic analgesics. Over the past three years continuous intravenous narcotic infusions have been used at this hospital to treat postoperative pain; recently a system has been devised whereby an hourly dose is given and the dispenser recharged every hour. The method used is cheap and reliable, and signs of overdosage may be easily checked by nursing staff. Side effects rarely occur. Fifty patients who had received intravenous infusions after undergoing major abdominal surgery were sent a questionnaire to assess postoperative pain, and the results were compared with those from 50 matched controls who had received intramuscular injections. Of those who replied, only four patients who had received the infusion had found the pain distressing compared with 13 controls. Continuous narcotic infusions are most effective in relieving postoperative pain and may be given cheaply and reliably.

Nerve blocks are an effective treatment in patients with many types of acute pain. However, they are much less effective in patients with chronic pain. Candidates for therapeutic nerve blocks should be carefully screened by: assessment of organic disease; evaluation of psychologic and behavioral disorders, and differential nerve blocks. The best candidates for therapeutic nerve blocks have known or inferred organic disease, minimal psychologic or behavioral disorders, and evidence of sympathetic or somatic pain mechanisms.

Massive kidney infarct, due to total occlusion of the main artery, is not a frequent process in clinical urology. The most frequent causes are endocarditis, arteritis, atheromatosis and traumatisms. The complete blockage of the renal artery means that the tissue irrigated by the same is bloodless and prone to necrosis and it must be taken into account that although the renal parenchyma cannot withstand for more than 1 to 2 hours the lack of a blood supply, the obstructions or ischemias of shorter duration cause tissue disorders of greater or lesser importance, affecting more quickly and more intensely the cells of the tubules, than those of the glomerules and later the connecting tissue. Clinically, kidney infarcts may sometimes go unobserved and on many other occasions their symptoms are by no means typical although the most characteristic feature is a more intense, sharp, acute pain with macroscopic hematuria, proteinuria and cylindruria and, in the radiological exploration, kidney "silence" but with the excretory duct intact shown by means of retrograde uretero-pyelography. The kidney angiography will reveal the existence of the arterial obstruction, with the resulting avascular image. Extrapremature surgical treatment would be ideal in the cases of massive infarct but this would also require an extrapremature diagnosis, which would enable the embolectomy (where necessary to be carried out, thereby saving the kidney. However, under normal working conditions, taking into account the period of time which inevitably elapses between the patient feeling pain in the kidney and his reaching the Emergency Department and the necessary examinations being carried out which enable the correct diagnosis to be made, the number of hours which have passed make attempts at conservative surgery completely useless. The authors present the case of a 37-year old patient who, 15 days after presenting a picture of right kidney colic, went to the Emergency Department in our Centre where the doctor on duty merely performed a symptomatic treatment and the patient was not admitted to our Department until several days later. In the different radiourographic examinations carried out, right kidney mutism was observed, as well as the permeability of the excretory duct. The aortography revealed the total occlusion of the right renal artery. As more than 20 days had elapsed since the patient first presented the colic pain and before we examined him, there was no other therapeutic solution but the performing of a nephrectomy. The examination of the organ removed confirmed the diagnosis but the origin of the arterial obstruction could not be clarified for sure.

The effect of single and repetitive electrical stimulation of the dorsal columns on cells in laminae IV and V of the ipsilateral dorsal horn at S1 was examined in spinalized cats. About two-thirds of the cells responded to thermal nociceptive cutaneous stimulation and of these most responded also to low threshold mechanical stimulation. The other one-third of the cells were innervated by mechanoreceptors including type I or Haarscheiben. A single shock to the dorsal columns typically caused short latency activation of the cells, followed by inhibition lasting about 100 msec. Several minutes of repetitive dorsal column stimulation (DCS) at 3 Hz or 50 Hz had no prolonged effect on about two-thirds of the cells. The rest of the cells were less responsive for up to 30 min after the cessation of 50 Hz. Assuming that the studied interneurons have a pain-mediating function, the results indicate that some cumulative and poststimulatory DCS suppression of pain may be ascribed to spinal mechanisms. The more effective and longer lasting suppression produced by DCS in pain patients would, however, be dependent on other types of interneurons, on suprasegmental loops and/or on effects on pathophysiological mechanisms which may be operative in the chronic pain state. The lack of cumulative inhibition in most of the cells in this study is compatible with the previous observation of a retained perception of acute pain during DCS in man.

This study investigates the capacity of the MMPI to discriminate among groups of patients with different types of pain. When multivariate analysis of variance is used, the standard set of MMPI scales discriminates between acute pain and chronic pain but not between chronic pain of two different etiologies (surgical-iatrogenic vs. unknown). The three scales that discriminate acute from chronic pain patients are those in the "neurotic triad," Hs, D, and Hy. The possibility that the unknown pain etiology group could be broken down into psychogenic pain and undetected somatogenic pathology subgroups was explored using cluster analysis. This procedure did not yield any group of patients who could be identified as having chronic pain of psychogenic origin. These results suggest that the MMPI is not a reliable tool for the differential diagnosis of chronic pain. It appears, however, that patterns of findings are partly contingent on population characteristics. Researchers should be cautious about generalizing to populations other than those from which samples are drawn.
