1/96. Low power laser therapy and analgesic action.

    OBJECTIVE: The semiconductor or laser diode (GaAs, 904 nm) is the most appropriate choice in pain reduction therapy. SUMMARY BACKGROUND DATA: Low-power density laser acts on the prostaglandin (PG) synthesis, increasing the change of PGG2 and PGH2 into PG12 (also called prostacyclin, or epoprostenol). The last is the main product of the arachidonic acid into the endothelial cells and into the smooth muscular cells of vessel walls, that have a vasodilating and anti-inflammatory action. methods: Treatment was performed on 372 patients (206 women and 166 men) during the period between May 1987 and January 1997. The patients, whose ages ranged from 25 to 70 years, with a mean age of 45 years, suffered from rheumatic, degenerative, and traumatic pathologies as well as cutaneous ulcers. The majority of patients had been seen by orthopedists and rheumatologists and had undergone x-ray examination. All patients had received drug-based treatment and/or physiotherapy with poor results; 5 patients had also been irradiated with He:Ne and CO2 lasers. Two-thirds were experiencing acute symptomatic pain, while the others suffered long-term pathology with recurrent crises. We used a pulsed diode laser, GaAs 904 nm wavelength once per day for 5 consecutive days, followed by a 2-day interval. The average number of applications was 12. We irradiated the trigger points, access points to the joint, and striated muscles adjacent to relevant nerve roots. RESULTS: We achieved very good results, especially in cases of symptomatic osteoarthritis of the cervical vertebrae, sport-related injuries, epicondylitis, and cutaneous ulcers, and with cases of osteoarthritis of the coxa. CONCLUSIONS: Treatment with 904-nm diode laser has substantially reduced the symptoms as well as improved the quality of life of these patient, ultimately postponing the need for surgery.

2/96. The longer term effect of pulsed radiofrequency for neuropathic pain.

    pulse radiofrequency has been recently described as a technique to apply a relatively high voltage near a nerve but without the usual effects of a rise in temperature or subsequent nerve injury. In this set of case reports, the effect of pulsed radiofrequency (PRF) is described in patients with neuropathic pain syndromes which have been poorly controlled with other oral and invasive treatments. Whilst anecdotal, the results have been remarkable and should encourage further research into this technique. Observations from the basic science tend to support the concept that PRF may induce some sort of long-term depression in the spinal cord.

3/96. Central pain as a manifestation of partial epileptic seizures.

    Central pain of epileptic etiology is very rare. The frequency of painful sensations in epileptic seizures varies between 0.3 and 2.8%. We report a patient with short-lasting painful attacks in the right arm. Changes in the electroencephalography (EEG) and the effective treatment with anticonvulsants in contrast to the therapeutic failure of analgesics, lead to the diagnosis of partial epilepsy with painful seizures. magnetic resonance imaging (MRI) of the brain was normal, whereas a postcentral parietal site of seizure origin involving the secondary somatosensory area was suggested by electroencephalographic findings. The literature is reviewed for cases with pain as the sole or predominant symptom of epileptic seizures.

4/96. Neurological abnormalities associated with mobile phone use.

    Dysaesthesiae of the scalp after mobile phone use have been previously reported but the pathological basis of these symptoms has been unclear. We report finding a neurological abnormality in a patient after prolonged use of a mobile phone. He had permanent unilateral dysaesthesiae of the scalp, slight loss of sensation, and abnormalities on current perception threshold testing of cervical and trigeminal nerves. A neurologist found no other disease. The implications regarding health effects of mobile phones and radio-frequency radiation is discussed.

5/96. Experience with radiofrequency ablation in the treatment of pelvic recurrence in rectal cancer: report of two cases.

    PURPOSE: The aim of this study was to assess the efficacy of radiofrequency ablation in the treatment of pelvic recurrent rectal cancer. methods: Computed tomography-guided percutaneous radiofrequency ablation was performed by placing a LeVeen needle electrode into the tumor. Radiofrequency ablation was performed on three lesions in two patients with pelvic recurrent rectal cancer, where the tumors were unresectable and associated with poorly controllable pain despite local treatment consisting of chemoradiotherapy. RESULTS: There were no major complications during the radiofrequency ablation procedure, although one patient complained of a sensation of warmth in the pelvic region, which was reasonably tolerated. Case 1: Each of two lesions of pelvic recurrence, 3 or 4 cm in diameter, was treated once by radiofrequency ablation with placement of a needle electrode into the tumor mass. After the procedure, magnetic resonance imaging confirmed nearly complete necrosis of the tumors, and there was a sufficient relief of pain enabling discontinuation of an opioid. serum carcinoembryonic antigen returned to normal and there was no evidence of relapse six months after the treatment. Case 2: Radiofrequency ablation was performed by placing a needle electrode at two sites of a recurrent tumor 6 cm in diameter. Postradiofrequency ablation imaging showed viable tissue remnants along the tumor margin, but the treatment produced relief of pain. The procedure was effective in opioid dosage reduction and pain control within a limited time span. CONCLUSION: Radiofrequency ablation is a relatively readily maneuverable and safe local treatment for pelvic recurrence in rectal cancer and is considered a procedure worth applying with further accumulation of experience in clinical cases.

6/96. Lumbar sympathetic block for pain relief in two patients with interstitial cystitis.

    BACKGROUND AND OBJECTIVES: Interstitial cystitis (IC) is characterized clinically by lower abdominal pain, pain during urination, and increased frequency of urination. Treatment of the symptoms in IC remains challenging. We report effective treatment using lumbar sympathetic block for 2 patients with IC. CASE REPORT: A 63-year-old and 78-year-old woman were diagnosed with IC. Medical therapy with nonsteroidal anti-inflammatory drugs (NSAID), anticholinergics, and hydrodistention of the bladder failed to improve their symptoms. Subsequently, a continuous lumbar epidural block using 1% mepivacaine was used in these patients. A transient reduction of the symptoms in both patients was achieved. A lumbar sympathetic block with a neurolytic agent produced almost complete, and long-lasting relief of their symptoms. CONCLUSION: Lumbar sympathetic block using a neurolytic agent produced long-lasting pain relief in 2 patients with IC. Reg Anesth Pain Med 2001;26:271-273.

7/96. An unusual case of chronic neuropathic pain responds to an optimum frequency of intravenous ketamine infusions.

    The effective treatment of patients suffering from a variety of difficult pain syndromes, including phantom pain and other neuropathic pains, remains a clinical challenge. Neuropathic pain has been shown to respond to drugs that block the N-methyl-D-aspartate (NMDA) receptor, such as ketamine and amantidine. A 44-year-old woman with a previous right-sided forequarter amputation presented to the Palliative medicine Team complaining of neuropathic pain in her left arm, which was neurologically intact. The pain was treated with repeated infusions of intravenous ketamine. Twenty-one infusions were given over a period of four months. The pain intensity experienced by the patient lessened as the frequency of the ketamine infusions increased. This finding has not been described previously and supports the theory that there may be an optimum frequency of ketamine infusions to achieve adequate pain control.

8/96. Lower limb and back pain in guillain-barre syndrome and associated contrast enhancement in MRI of the cauda equina.

    This study assesses the frequency of lower limb and back pain in children with guillain-barre syndrome and reviews the magnetic resonance imaging results of those undergoing spinal imaging. Over an 8-y period, nine children presented with various combinations of severe back pain, leg pains, impairment of gait and bladder dysfunction. guillain-barre syndrome was confirmed on clinical examination and peripheral electrophysiology (n = 8). magnetic resonance imaging in four patients, following contrast injection, showed enhancement of the cauda equine and, additionally, of the cervical nerve roots in one of the patients. A further patient, who was not scanned with contrast, had abnormal thickening of the lumbar roots. carbamazepine and steroids were effectively used for analgesia in three cases. All the patients recovered. Conclusion: guillain-barre syndrome should be considered in the differential diagnosis of children presenting with back and/or leg pain. early diagnosis ensures prompt monitoring for autonomic dysfunction and respiratory compromise.

9/96. Treatment of proctalgia fugax with botulinum A toxin.

    Two recent studies described a temporal association between a high-amplitude and high-frequency myoelectrical activity of the anal sphincter and the occurrence of proctalgia, which suggest that paroxysmal hyperkinesis of the anus may cause proctalgia fugax. We describe a single case of proctalgia fugax responding to anal sphincter injection of clostridium botulinum type a toxin. The presumed aetiology of proctalgia fugax is discussed and the possible mechanism of action of botulinum toxin (BTX) in this condition is outlined. Botulinum A toxin seems to be a promising treatment for patients with proctalgia fugax, and further trials appear to be worthwhile for this condition, which has been described as incurable.

10/96. Percutaneous radiofrequency lesioning of sensory branches of the obturator and femoral nerves for the treatment of hip joint pain.

    BACKGROUND AND OBJECTIVES: The sensory innervation of the hip joint includes the sensory articular branches of the obturator and femoral nerves. In this report, we retrospectively evaluated 14 cases in which hip joint pain was treated by percutaneous radiofrequency lesioning of sensory branches of obturator and/or femoral nerves. methods: Fourteen patients who had hip joint pain and underwent percutaneous radiofrequency lesioning of sensory branches of obturator and/or femoral nerves were studied. In all cases, intra-articular hip joint block or articular branch block of obturator nerve with local anesthesia was transiently effective. Radiofrequency lesioning was performed at 75 degrees C to 80 degrees C for 90 seconds using an RFG-3B generator and Sluijter-Mehta cannulae kit (Radionics, Burlington, MA) for the obturator nerve in 9 patients and for both the obturator and femoral nerves in 5 patients. To assess pain intensity, a visual analog scale (VAS) was used. RESULTS: The VAS scores before and after the radiofrequency lesioning were 6.8 /- 0.9 and 2.7 /- 1.3, respectively. Twelve patients (86%) reported at least 50% relief of pain for 1 to 11 months. There were no side effects or motor weakness observed. CONCLUSIONS: Percutaneous radiofrequency lesioning of sensory branches of the obturator and femoral nerves is an alternative treatment in patients with hip joint pain, especially in those where operation is not applicable.
