Complex regional pain syndrome type I of vascular origin is difficult to detect unless the classic symptoms and signs exist and/or overt extremity trauma has precipitated the pain. The diagnosis is confirmed by relief of pain following a sympathetic nerve blockade. A 36-year-old woman with arterial occlusive disease of the right lower extremity presented with burning pain and hyperesthesia after sprain had occurred which was accompanied by motor weakness of right ankle. A lumbar sympathetic ganglion blockade with 2% lidocaine 10 ml and triamcinolone 80 mg produced prompt improvement of the pain and motion.

Rectal tenesmus is a persistent, painful and ineffectual sensation of straining at stool or opening of the bowels. The pain is usually spasmodic in nature and most commonly encountered in patients with carcinoma of the rectum or other pelvic organs. In 1988, Bristowand Foster reported that patients with severe spasmodic painful tenesmus were relieved with chemical sympathectomy. In 1990, Plancarte introduced block of Ganglion impar. This technique is proposed as an alternative means of managing localized perineal pain of sympathetic origin. Ganglion impar block was performed on a 54-year-old female patient when analgesic or psychotropic drugs failed to control the symptoms of post-traumatic severe spasmodic painful tenesmus. Postoperatively, patient was free of tenesmoid pain for only 7 days. We then performed neurotomy by RF lesion generator which provided complete pain relief.

Bilateral trigeminal neuralgia is uncommon and usually occurs in 1% to 11% of patients with trigeminal neuralgia. There has been no report of a patient with bilateral trigeminal neuralgia in Korea. Based on our review, the incidence of bilateral trigeminal neuralgia among the trigeminal neuralgia patients who visited our pain clinic numbered 0.7% (4 out of 531). This is much lower than those of other previous studies. This lower incidence might be explained by the fact that we excluded those patients with mild bilateral trigeminal neuralgia which did not require treatment and also patients whose symptom on controlateral side was relieved by injection of local anesthetics for that side. Among the four patients with bilateral trigeminal neuralgia, three patients received alcohol block of the branches of trigeminal nerve and one refused the treatment. Overall, three patients maintained good or excellent pain relief without any serious complications throughout the follow-up period.

Meralgia paresthetica is a disorder characterized by a pain or dysaesthesia, or both, in the anterolateral aspect of the thigh caused by entrapment or neurinoma formation of the lateral femoral cutaneous nerve. Currently available modes of therapy include conservative treatment, lateral femoral cutaneous nerve block with steroids and local anesthetics, and surgery. At our neuro-pain clinic, w recently encountered three cases of meralgia paresthetica, all of which were treated by lateral femoral cutaneous nerve block. In which of them, two cases were successfully treated but one case was associate with pain relapse due to entrapment of lateral femoral cutaneous nerve by a retroperitoneal mass, schwannoma. In this paper we report our experience along with a review of the current literatures.

This is a retrospective analysis of 158 patients who visted our Neuro-Pain clinic, April 1992 to March 1996, suffering from trigeminal neuralgia. Most patients received nerve blocks in its triggering peripheral branches of pain. All patients experienced pain relief for 3 months after initial successful nerve block. Twenty two patients complained of recurring pain within 4 to 32 months. Mean duration of pain relief was as follows: infraorbital nerve block 15.2 months, maxillary nerve block 16.8 months, and mandibular nerve block 23.4 months. Demographic and clinical characteristics of all patients were also evaluated. This study demonstrates that alcohol block is a safe and effective method of treating trigeminal neuralgia.

A 20-year-old male patient developed severe right leg pain, hyperesthesia and allodynia after multiple lumbar epidural blocks. His pain was neuropathic pain (complex regional pain syndrome type I). The patient was treated with repeated administration of epidural ketamine at the rate of 0.2~0.7 mg/kg on multiple occasions. Complete relief of pain was achieved.

Tic convulsif is a syndrome restricted to paroxysmal dysfunction of the fifth and seventh cranial nerves. It occurs predominantly in women over the age of 50 years and is usually associated with an ectatic vertebrobasilar artery - less frequently an arteriovenous malformation or cholesteatoma - which compresses the trigeminal and facial nerve roots in the postetior fossa. In rare instances this syndrome may be caused by brain tumor. Because of the high incidence of posterior fossa lesions in painful tic convulsif, a complete neurological evaluation including computerised transaxial tomography should be performed in every case. We experienced a case of trigeminal neuralgia(mandibular division)and contralateral hemifacial spasm.

Hemifacial spasm commonly occurs in muscles about the eye, but may also involve or spread to the entire side of the face. One hundred and seventy eight patients with hemifacial spasm visited our Neuro-Pain clinic from January 1992 to April 1996. There were 121 female and 57 male patients, a 2.1:1 ratio respectively. Largest percentages of patients were in the 50 year old range. Among them, 96 patients were treated by facial nerve block or O'Brien block. In most cases, induced facial palsy disappeared within one or two months. Among the 96 patients who received nerve block, 46 patients received a second block within 5 to 24 months. The average interval from first and second nerve block was 11.5 months. After nerve block, all patients were free from spasm for 1 to 21 months. We conclude that facial nerve block is a satisfactory and reliable method for the treatment of facial spasm.

Retrospective analysis, of 1,734 patients treated for nerve block from October 1991 to March 1994. Largest percentage of patients were in the 50 year old range, with a distribution of 44.9% male and 55.1% female. Treatments were for ailments of: Low Back Pain 17.3%, Multiple Contusion 10.5%, and Cancer 10%. Most common nerve block was epidural block 38.6%, followed by stellate ganglion block 38.4%, intercostal block 5.4%, and suprascapular nerve block 5.2%. Nerve block under fluorscopic guide were as follows: facet joint block 34.1%, lumbar sympathetic ganglion block 13.6%, and celiac plexus block 12.9%.
