In order to study effect of corpus callosotomy for epileptic lesions located at sensory-motor cortex/cortices, changes in amplitude, frequency of background activity and frequency of abnormal discharges of postcallosotomy electroenencephalography(EEG) recordings were observed in the crystal penicillin induced epileptic models of rats. In control group of 10 rats, simple right(craniotomy was) done and needle electrodes were bilaterally inserted into parietal and occipital scalp, connected to EEG recording system. Experimentally induced epileptic group was obtained by instillation of 1-2 drops of crystal penicillin solution(800,000 IU/ml) at right parietal area(20 rats). Postcallosotomy group was consisted of the animals streotactically performed callosotomy with blunt ended stainless steel, sized 3 mm, width and 0.5 mm, thickness(20 rats). Preoprative and postoperative EEG recordings were obtained in each animals over 20 minates. The results were as follows; 1) Bialteral synchronous epileptic discharges were shown in experimetally induced epileptic group, which compared to control group. 2) Section of the corpus callosum caused the abolition of bilateral synchronous epileptic discharges, when compared to experimentally induced epileptic group. 3) Frequency of abnormal discharges in the contralteral hemisphere was more decreased than crystal penicillin-instillated lesion in postcallosotomy group. 4) The Background activity of postcallosotomy group was slower than control group. From the results of EEG analysis, corpus callosum might paly a important role in formation of bilateral synchronous discharges and callosotomy was seemed to be an effective method to control crystal penicillin induced epileptic rats, which had epileptic focus in sensory-motor cortex.

The "sinus pericranii" is a rare vascular anomaly involving an abnormal communication between extracranial and intracranial venous system, which usually involves the superior sagittal sinus, sometimes the transverse sinus. It is found beneath or in the periosteum of the cranial vault and is connected with an intracranial sinus through anomalous diploic veins of congenital or acquired origin. It is benign scalp mass, and should be differentiated from vascular anomalies of the scalp and cystic masses of the scalp communication with the cerebrospinal space. The authors present 2 cases of sinus pericranii which was spontaneously developed without any history if head injury. The lesion was found to be changed in it's volume according to patient's head position. Clinical characteristics of sinus pericranii is discussed.

Through the use of stereotactic neurosurgical operation, some authors have employed chronic electrical stimulation of the dentate nucleus spasticity and each trial on spastic patients has show marked clinical improvement. We investigated the electrophysiological changes of cats after stereotactic electrical stimulation of the dentate nucleus to elucidate the possibility of clinical application and to evaluate the clinical results. The M-wave is an initial response and the F-wave is a late response in the electromyography of a muscle, which is stimulated by its original controlling nerve itself. There is evidence that the size of the F-wave is dependent on motor neuron excitability and its amplitude is increased significantly at spastic condition. If such a relationship exists, procedures which are carried out to relieve spasticity might be exerted to change the F-wave size and thus it might be possible to use the F-wave as an objective monitor during electrical stimulation of the dentate nucleus. We investigated this possibility in experiments on 10cats weighing between 2.7 Kg and 4.4 Kg. We studied the changes of M and F waves, recorded in EMG, after stereotactic stimulation to cerebellar dentate nucleus in cats. The results were as follows : 1) The change of mean value of M-wave amplitude was not significant(control group, 3591+/-1029 microV : stimulation group, 3424+/-927 microV, P>0.05). 2) The mean value of F-wave amplitude was significantly reduced about 56.7% after the dentate stimulation(control group, 443.2+/-119 microV : stimulation group, 251.3+/-99.4 microV, P<0.05). 3) The F/M ratio also significantly reduced, about 56.8% after the dentate stimulation(control group, 12.5+/-1.9%, stimulation group, 7.1+/-1.2%, P<0.05). Our experimental results demonstrated that the dentate stimulation markedly decreased the size of F-wave amplitude and F/M ration in the experimental cats and we concluded that these electrophysiological changes can be applied as a parameter of clinical evaluation of electrical dentate stimulation for the spasticity.

PURPOSE: To report the clinical results from surgical treatment for clavicle shaft fracture by percutaneous intramedullary fixation with Steinmann pins. MATERIALS AND METHODS: Between January 2004 and June 2014, the medical records of 135 patients who underwent percutaneous intramedullary fixation with Steinmann pins were reviewed. The mean follow-up periods were 15 months. The functional results were evaluated with The Disabilities of the Arm, Shoulder and Hand (DASH) score and Constant score. The clinical results were evaluated with the shortened length of the clavicle, length of surgical wound, operation time and Kang's criteria. RESULTS: The mean bone union period was 11.6 weeks (8–16 weeks). The mean DASH score was 11.8. The mean Constant score was 91.2. The mean shortened length of the clavicle was less than 20 mm. The mean length of surgical wound was 1.2 cm (0.7–1.5 cm). The mean operation time was 18 minutes (10–35 minutes). Using Kang's criteria, 131 out of 135 patients (97.0%) showed good results. Complications included were 3 pin migrations and 2 non-unions. CONCLUSION: Percutaneous intramedullary fixation with Steinmann pins showed good results for treating clavicle shaft fracture.

Painful 203 patients with chronic pain were treated with transcutaneous electrical nerve stimulation in the CNS & Pain Management Institute of St. Paul's Hospital, Catholic Medical College, Seoul, Korea. Each patient was instructed on the method of autostimulation with variations in for an initial observation frequency and intensity. The effect were recorded daily period of about 3 weeks. The patients were evaluated at suitable intervals and asked to grade the relief of pain on a percentage scale. Four categories of pain relief were established : 80% to 100%(A), 60% to 80%(B), 30% to 60%(C), 0% to 30%(D). This procedure with modern, solid state devise has been tried enough that it can be recommended as a potentials treatment for most types of pain about 90% of pain problems can be managed in this way. The mode of action of transcutaneous Electrical nerve stimulation is most simple and can not be explained only by gate control theory.

PURPOSE: We report a case of Purtscher-like retinopathy following the removal of a dislocated IOL and scleral fixation of a new IOL. METHODS: A 60-year-old man presented with sudden visual loss of the right eye. An ophthalmologic examination revealed IOL dislocation. He underwent removal of the dislocated IOL and scleral fixation of the new IOL. Visual acuity was 0.02 in the right eye on the second postoperative day. A fundus examination and fluorescein angiography were performed. RESULTS: A peripapillary multiple cotton wool spot, pale macula and cherry red spot were noted in the right eye. Fluorescein angiography showed arteriolar obstruction around the macula and leakage of the mild arteriolar fluorescein dye. At one month follow-up, macular edema, hemorrhage and peripapillary cotton wool spots were increased. CONCLUSIONS: This case of Purtscher-like retinopathy following scleral fixation of the IOL did not have any obvious etiologic cause.

From March 1966 to July 1988, 22 patients were diagnosed as discitis among the 2106 operation with total or hemilaminectomy in Department of Neurosurgery of Catholic University Medical College. Main symptoms were severe low back(95%) and buttock pain(86%). Physical examination showed severe paravertebral spasm and tenderness. The erythrocyte sedimentation rate was always elevated in all cases and averaged to 43 mm/hr. X-ray examination of the lumbar spine showed typical findings of decreased intervertebral space, subchondral sclerosis and bony fusion. In bacterial culture staphylococcus aureus and streptococcus epididymis were grown. Good long-term results were seen in all cases.

We have reviewed 10 cases of hypertensive intracerebral hematoma operated within 48 hours following apopletic attacks. Computerized tomography permits the choice of the most direct approach to the hematoma. Postoperative CT and Evoked potential studies provides good control of the program of the hematoma removal. In early operation we have noted that intracranial pressure has not yet increased and the cerebral edema is minimal. Microsurgical technique with CO2 laser mes was used for bleeding controls and evacuation of the hematoma. At the three months follow-up study, 8 patients could walk unaided or with a cane, one was confined in bed and are had died.
