The blow-out fracture can be reconstructed by various autogeneous and alloplastic material. Particulate, nonresorbable hydroxyapatite is currently one of the choice of implant material available for reconstruction of blow-out fracture. Hydroxyapatite is radiopaque ceramic, physically and chemically similar to enamel and cortical bone. It is a biomaterial derived from natural corals to use as a bone graft substitute. And we looked into the clinical usefulness of 2 type of hydroxyapatite with their advantages and disadvantages in reconstruction of blow-out fracture. 183 patients with blow-out fracture who underwent surgical reconstruction with two types of hydroxyapatite from March 1933 to July 1977 have been analyzed the results of surgical reconstructions, and have been followed up for more than a year. And the condition of formerly inserted hydroxyapatite was observed in the patients who needed 2nd surgical reconstruction due to the enophthalmos. The disadvantages of hydroxyapatite are fragility, size and contour limitations. In spite of these demerits, hydroxyapatite can be one of the prospective materials to reconstruct orbital floor. Through the clinical experiences for 5 years, we have not found any of complications of exposure, infection, and foreign body reaction. Low rates of diplopia, limitation of ocular movement, and enophtalmos was observed. Hydroxyapatite was well adherent to adjacent orbital bone in most patients who needed secondary reconstruction for enopthalmos. In conclusion, our study shows that the availability of hydroxyapattite in reconstruction of blow-out fracture is recommendable, with low complication rates. Hydroxyapatite important appears to be well tolerated, and provides useful alloplastic prosthesis with few problems in reconstruction of blow-out fracture.

OBJECTIVE: The authors reviewed experience with patients harboring intracerebral hematoma (ICH) treated by stereotactic computed tomography (CT) guided thrombolysis and aspiration and evaluated feasibility, safety and prognostic factors of this procedure. METHODS: One hundred and ten patients with supratentorial ICH >25 ml without underlying structural etiology or coagulopathy were recruited. The patients with Glasgow Coma Scale (GCS) <5 were excluded. A catheter was directed stereotactically into the ICH under CT guidance. Hematoma aspiration was followed by instillation of urokinase. This was repeated every 6 hours until less than half of its initial volume remained. For analysis of prognostic factors, we classified them into two groups;good (Glasgow Outcome Scale (GOS) > or =4) and bad (GOS<4) prognosis group, and performed comparative analysis between two groups. RESULTS: Mean age was 59.8 years. The baseline hematoma size ranged from 15 to 72 mL. ICH volume reduced by an average of 74.2%. At 6 months after the procedure, 56 patients had achieved a good recovery, 29 patients were dependent, and 10 remained vegetative. Fifteen patients died in hospital. The main good prognostic factors were young age, small ICH volume, high GCS, absence of rebleeding, underlying disease and complications. CONCLUSION: CT-guided thrombolysis and aspiration appears safe and effective in the reduction of ICH volume. Patients of ICH presenting with bad prognostic factors should require frequent radiological investigation and more meticulous procedure. Further studies are needed to assess optimal thrombolytic dosage and must include controlled comparisons of mortality, and disability outcome.

The end of this month is the 30th birthday of Journal of Korean Neurosurgical Society. Since the first issue of Journal of Korean Neurosurgical Society published in October, 1972, it has been developed in its quality as well as the quantity. More than 4000 articles have been published and tremendous contribution for the development of Korean Neurosurgical Society was made by the journal. The authors review the history of Journal of Korean Neurosurgical Society including the problems in this situation and suggest the way to make the journal as an internationally famous one.

Zonisamide was administered to 20 patients with refractory epileptic seizures. The mean duration of the administration was 6 months, and the mean dosage was 7.2 mg/kg/day. The efficacy of zonisamide was rated remarkable in 15% of the cases, improvement in 40%, and no change in 45%. The response rates of zonisamide were 62.5% for myoclonic seizures, 50% for tonic-clonic seizures, 80% for atonic seizures and 33.3% for atypical absence seizures. There was no correlation between the clinical response and dose or serum concentration of the drug. The adverse effects were observed in 35% of the cases which were drowsiness, dizziness, ataxia, nausea, and vomiting. In all cases, however, the administration of zonisamide could be continued.

PURPOSE: The purpose of this study was to identify how empathy mediates the relationship between teachers' knowledge of Attention Deficit Hyperactivity Disorder (ADHD) and educational interventions. METHODS: A survey for structural equation modeling was conducted with 334 teachers from 61 schools in D and Y cities in Korea. Data were collected from April 2012 to July 2012 through self-report questionnaires using standardized instruments. The data were analyzed using SPSS Win 20 and AMOS 20, and Sobel tests were conducted to determine the significance of mediation and Bootstrapping tests to construct confidence intervals. RESULTS: Teachers' empathy provided complete mediation between teachers' knowledge and educational interventions in classrooms. Results showed that empathy contributes positively to educational interventions in ADHD by increasing understanding of children with ADHD and the situation. CONCLUSION: Based on the findings of this study, teachers need to enhance their empathy towards students with ADHD to increase the effectiveness of their educational interventions for ADHD. These results suggest the importance of focusing on increasing teachers' empathy in the classroom in order to provider better education interventions for children with ADHD.

BACKGROUNDS: With the recent elucidation of genetic basis of Rh blood group, it is now available the molecular genotyping methods for Rh blood typing. These can be used when serological typing is difficult. This study was conducted to investigate the usefulness of Rh genotyping method for Koreans. METHODS: Genotyping for Rh C/c and E/e was performed in peripheral blood DNA samples from 34 blood donors by polymerase chain reaction using sequence-specific primers (PCR-SSP). The PCR determined genotypes were compared with serologically determined phenotypes. RESULTS: The Rh C/c and E/e genotyping results of 34 blood donors were full concordance with the results of their serologic phenotyping. CONCLUSIONS: Rh genotyping method on the basis of Rh genetic model can be applied to Koreans. This genotyping method would be useful tool in prenatal Rh typing of fetus at risk of hemolytic disease and when serotyping is not available for example massive transfusion.
