PURPOSE: The aim of our study was to evaluate the usefulness of MR imaging in cases of traumatic brachial plexus injury. MATERIALS AND METHODS: We evaluated 25 patients with traumatic brachial plexus injury as seen on MR images prior to surgical exploration and repair. MR images were retrospectively evaluated for nerve root avulsion and pseudomeningocele, and postganglionic lesions. Results were correlated with final diagnosis after surgical exploration . RESULTS: One hundred and four of 125 root levels (83%) were adequately imaged. Neve root avulsion was shown at 28 levels(54%). Avulsion with or without pseudomeningocele was seen at 37 levels(71%)(80% sensitivity, 91% specificity). The presence of ten of 12 postganglionic lesions (83%) was revealed by MR imaging. CONCLUSION: MR imaging is valuable for revealing preganglionic nerve root avulsion in patients with traumatic brachial plexus injury or postganglionic lesions.

Clinical experience using different anesthetic methods for intravenous regional anesthesia in extremities was compared, To group 1 (22 cases, 20 for upper extremity and 2 for lower extremity surgery, with 5 min. limb elevation) 1.5mg/kg Lidocaine hydrochloride was administered and a single pneumatic tourniquet applied. For both group 2 (15 patients, 10 for upper limb and 5 for lower limb operations with limb elevation) and group 3 (11 cases, all for upper extremity operations, but Esmarch bandages instead of pre tourniquet elevation) 3. 0 mg/kg Lidocaine hydroehloride was used and a second tourniquet placed distal to the first. In all groups the anesthetic concentration was 0. 5 and 0. 25 per cent for the upper and lower extremities respectfully. Pneumatic tourniquet pressure applied was 250 mmHg for the upper limb and 500mmHg for the lower. Excellent anesthesia resulted in 68. 2 per cent in group 1, 73.3 per cent in group 2, and 100 per cent in group 3. No serious complications were encountered. Incidence of incomplete anesthesia and/or tourniquet pain could be decreased by increasing the anesthetic concentration, using a secondary tourniquet, and by selecting the region to be anesthetized (upper extremities in favor of the lower). It is concluded that intravenous regional anesthesia is simple, effective and safe and is recommended for ambulatory patients, emergency operations and for patients for whom general anesthesia is deferred.

Postoperative pain control is very important not only for the relief of pain. but in the prevention of respiratory acidosis, pulmonary complications, emotional disturbances and sleeping disturbances etc. Jn spite of its significance there are a few studies on postoperative pain control in medical literature. Techniques have been developed for postoperative pain control since the 19 century, for example analgesics, inhalational agents, regional block, hypnosis and accupuncture. However none of these techniques was satisfactory because of various complications. The intermittent intramuscular injection of narcotics (e.g. meperidine) has been used most widely pto the present. There have been many complications, induding addiction, from this method. Our study was done in the recovery room with intramuscular injections of Thalamonal to fully awake patients, with 20 cases each having operation done in the upper abdomen, lower abdomen, and in other sites. We evaluated the results for the requirement of meperidine after the adminstration of Thalamonal. This was compared with the control group. There were 85% of cases that did not require the injection of meperidine. One case was complicated by hypotension, but this patient was improved with routine management for , hypotension. Other complications were not found.

To increase the success rate of intraocular pressure control in recalcitrant glaucoma, Ahmed glaucoma shunt has been used recently. Application of mitomycin C(MMC) during Ahmed implantation may be speculated to increase the success rate by decreasing the fibroblast proliferation and colagen deposition in the filtering capsule. To find out histological change with the use of MMC in the capsule of seton implant, a rabbit model of the Ahmed implant was created to obtain a serial histological specimens over 6 months. Ahmed S1 implant were implanted in 10 normal white rabbits. Five rabbits were treated with 0.04% MMC solution during the implantation under subtenon space(group 1) and the remaining ones were not(group 2). The rabbits were sacrificed at 1, 3, and 6 months to obtain histological specimen of the bleb capsules in each group. Light microscopic examinations were performed after hematoxylin and eosin staining. In group 1(MMC application group), the thickness of fibrous capsule was 0.6mm at 1 month, 0.48mm at 3 months, and 0.4mm at 6 months serially. The number of fibroblasts was 139/mm3 at 1 month, and 82/mm3 at 6 months. In group 2, the capsule thickness was not significantly different compared with roup 1 at 6 months. IN conclusion, during the period over 6 months period, there was no significant difference in thickness of bleb capsule in the two groups although the number of fibroblasts was 3 times denser in group 2 than in group 1.

Viscoelastic substance which is one of the most important thing in anterior segment surgery sells many kinds as to its unique properties. The complications during its use are acute postoperative intraocular pressure elevation, corneal edema, severe ocular pain, blurred vision. The extent of elevation, peak time and normalized time of intraocular pressure can be varied by operative technique, amount of residual viscoelastics in anterior chamber, kinds of viscoelastics. To compare the safety of Healon GV and Provisc with Healon, we injected the same amount of those three viscoelastics into anterior chamber of 27 rabbits divided by three groups and examined the degree and change of intraocular pressure elevation, corneal edema, intraocular inflammation, maintenance of anterior chamber. Healon GV showed the persistent intraocular pressure elevation immediately after injection and normalized at 24 hours. Healon and Provisc showed elevated pressure at 7 and 5 hour but normalized within 12 hour. Corneal thickness increased significantly at 1 to 7 hour in Healon and Healon GV group and continued to 24 hour in Healon GV group and there was no significant pressure change in Provisc group compared with preinjection status. There were no significant differences in intraocular inflammation, amintenance of anterior chamber between three viscoelastics. Healon GV shoed more frequent, higher intraocular pressure elevation as compared to the other two viscoelastics, but pressure was normalized within 24 hour. From the above results, it is concluded that Healon GV can be used well with caution and Provisc can be used widespreadly due to its minor complication, too.

Cerebral cysticercosis, is unfortunately, a frequent disease in Korea. Cysticercosis in man is exclusively due to the development of Taenia solium larvae, called Cysticercus cellulosae, which is a frequent parasite in the pig. The clinical symptoms which are varied and similar to those of any other tumor of the brain, are depent on the location, number of parasite, intensity of infestation and susceptibility of the host. The headache, vertigo, nausea and vomiting, appearing periodically, and chiefly after a rapid change in the position of the head, were indicative of a cysticercus lying free in the fourth ventricle. We have recently experienced a case of cerebral cysticercosis which involved the 4th ventricle. A forty-year-old man was aditted to the Department of Neurosurgery, College of Medicine, Korea University in June, 1978 because of severe headache, repeated vomiting and diplopia which progressed gradually for two months previous to admission. On admission, there were no specific localizing and lateralizing neurological abnormalities except for signs of mild cerebellar dysfunction and signs of increased intracranial pressure accompanying with bilateral optic papilledema. Conray ventriculogram disclosed the dilation of proximal portion of the 4 th ventricle and smoothly rounded central filling defect of the 4 th ventricle. Brain C-T Scan demonstrated the marked dilation of 4 th ventricle in found shape without evidence of midline shift or compression. This enlarged 4 th ventricle with water density was shown no evidence of the contrast enhancement. Suboccipital craniectomy was performed and a cystic mass was removed from the fourth ventricle. Pathological diagnosis of the specimen was cysticercosis. Following surgery, the patient's symptoms cleared up and neurological deficits and papilledema improved gradually.

Thirty consecutive anesthesia records of transurethral resection (TUR) have been reviewed. Patient's physical status, anesthetic management and complications were also discussed. Operations in this series were classified as follows: 25 cases of TUR for carcinoma of the prostate, 3 cases of bladder tumor. In all the thirty cases of TUR, circulatory diseases, such as hypertension were encountered most frequently. (10 cases) The patients had the highest mean age(66.5 years old) and their physical status was almost all ASA class II or III. Hypotension occurred in 1 patient during TURP. There was no death associated with anesthesia and operation in this study. Pain control after operation with epidural block was satisfactory in nearly all cases. Continuous epidural anesthesia for TUR and pain control after operation was desirable.
