Dyke-Davidoff-Masson syndrome is a rare clinical syndrome consisting of hemiatrophy of cerebral hemisphere, enlargement of ventricles and prominent pneumatization of petrous pyramid of the temporal bone. Its clinical manifestations are hemiparesis, several types of seizure, mental retardation and other neurologic deficits. We experienced a case of Dyke-Davidoff-Masson syndrome in a four months old boy who visited to our department due to right side upper extremity weakness and infantile spasm. The brain magnetic resonance imaging showed marked hemiatrophy of left cerebral hemisphere and enlargement of left lateral ventricle. So with the review of literatures, we report a case of Dyke-Davidoff-Masson syndrome with infantile spasm.

The etiologic factors of tennis elbow have been obscure in spite of increased concern and study. The true pathologic changes in tennis elbow are also not well established. The authors anslized 300 tennis players for a history of tennis elbow, finger size, body weight,weight and grip size of racket etc. The results were as follows; 1. 68 among 300 players have suffered from tennis elbow more than one time (22.7%). 2. There were no difference in correlation between body weight and racket weight. 3. Most players have used improper grip, especially in those who have suffered from tennis elbow.

Septo-optic dysplasia, as first described by de Morsier, is a rare developmental anomaly of absent or hypoplastic septum pellucidum, a primitive optic vesicle, and dysplasia of the optic nerve, chiasm, and optic tracts. It is a common cause of hypopituitarism in children and has variable hypothalamic-pituitary dysfunction. We experienced a case of septo-optic dysplasia in 5 month old female baby who presented with developmental delay and seizure. A magnetic resonance imaging of the brain showed absence of the septum pellucidum and the fundoscopic examination disclosed the absence of left optic disc and atrophy of right optic disc.

This study was undertaken to investigate the morphologic changes following flushing, preservation and reperfusion procedures in a canine lung allotransplantation model. Donor lungs were flushed with modified Euro-Collins (MEC) solution, low potassium dextran glucose (LPDG) solution or University of Wisconsin (UW) solution, then stored at 10oC for 20 hours. Light microscopic and electron microscopic features of the lungs were examined after flushing, preservation and 2 hours after reperfusion. After flushing light microscopy showed focal mild alveolar collapse and interstitial edema. After preservation the lung tissue showed multiple foci of alveolar collapse, consolidation, and alveolar epithelial cell damage. After reperfusion the lung tissue showed diffuse alveolar collapse, consolidation and many destroyed cellular debris in the alveolar lumina. After flushing electron microscopy showed focal alveolar collapse and mild swelling of type I epithelial cells. After preservation both type I epithelial cells and endothelial cells were swollen and destroyed focally. Some type I epithelial cells were detached from the basal lamina. The endothelial cells showed luminal protrusion of tactile-like structure and vacuoles of the cytoplasm. After reperfusion the lung tissue showed fibrin material in the alveoli, prominent type I epithelial cell swelling with fragmented cytoplasmic debris and marked endothelial cell swelling with vacuoles or tactile-like projections. The alveolar macrophages showed active phagocytosis. After preservation scanning electron microscopic examination of the pulmonary arteries showed multiple patchy areas of swelling or conglomerated lesions in the inner surface of the pulmonary arteries. In conclusion, the ultrastructural changes associated with flushing were mild in severity, the donor lungs were injured during the preservation, and further damage occurred during the reperfusion.

Vestibular schwannoma (VS) is a benign tumor typically originated in the schwann cell of vestibular nerve and usually accompany hearing symptom. Microsurgical removal and radiosurgery have a great role for the treatment of VS. Recently radiosurgery has been considered as an alternative or primary treatment for VS with the tremendous increase of patients who were treated with gamma knife radiosurgery (GKS) though microsurgery still takes the premier. By many published results, it is proved that GKS is a effective and noninvasive technique for VS, especially small sized tumors with satisfactory tumor control rate. The authors assumed that GKS can be expected to achieve satisfactory tumor control rate for small VS under 5 cc in volume. A major interest regarding radiosurgery nowadays is to determine the optimal radiation dose for hearing preservation to improve the quality of life of patients. The more high radiation dose are used for effective tumor growth control, the more radiation-related complications like as hearing deficit, the impairment of other cranial nerve function are increased. Since 1990's the mean radiation dose for tumor margin was more than 18 Gy, but there were high complication rate in spite of good tumor growth control. After the year of 2000, under the influence of advanced neuro-imaging techniques and radiosurgical planning system which enable clinicians to do more precise planning, marginal dose for VS has been decreased to 12-13 Gy and the radiation-related complications has been reduced. But because there may be a unexpected radiationinduced complications as time goes by after the latency period, optimal radiation dose for VS should be established on the basis of more long term follow-up observation.

BACKGROUND: Laryngoscopy and tracheal intubation for general anesthesia are potent stimuli to the cardiovascular system due to sympathetic stimulation. The aim of this study was to compare the hemodynamic responses with different administration routes of lidocaine on blood pressure and heart rate changes associated with tracheal intubation. METHODS: Sixty patients were randomly assigned to spray group (Group 1, n=20) received 10% lidocaine 1.5 mg/kg spray to intratracheally immediately before tracheal intubation, IV group (Group 2, n=20) received 2% lidocaine 1.5 mg/kg intravenously before 90 sec tracheal intubation and control group (Group 3, n=20). Anesthesia was induced with thiopental 5 mg/kg IV, vecuronium 0.1 mg/kg and 50% N2O-O2- 2vol % enflurane. After 5 minutes, tracheal intubation was performed. Mean arterial pressure and heart rate were measured at preintubation and immediately postintubation, 1, 3, 5 mins after tracheal intubation. RESULTS:The differences of mean arterial pressure which were measured at preintubation and immediately postintubation and 1 minute after intubation in group 1 were significantly lower than those in other group (p<0.05). The differences of heart rate which measured at preintubation and 1 minute after intubation were lower than those in group 3 (p<0.05). CONCLUSIONS: For the suppression of sympathetic stimulation following tracheal intubation, 10% lidocaine spray to the laryngotrachea is an effective method to suppress cardiovascular response.
