We evaluated the effectiveness of photoastigmatic refractive Keratectomy(PARK) by excimer laser on patients with compound myopic astigmatism. Spherocylindrical PARK was performed on 181 myopic eyes with astigmatism(mean spherical equivalent : -6.61 D, range : -1.88~-14.5 D) using the visx excimer laser. The eyes were divided into three groups according to the amount of desired astigmatic correction : Group 1(-0.5~-1.0 D), Group 2(-1.25~3.0 D), and Group 3(-3.25~-5.5 D). Patients were followed up for 6 months. Uncorrected visual acuity at postoperative 6 month, was 0.80+/-0.27 in Group 1, 0.79+/-0.19 and 0.71+/-0.21bin Group 2 and 3 respectively. The mean spherical equivalent refraction was -0.24 D 6 months after PARK. Mean astigmatism was reduced from preoperative -0.85+/-0.51 D to postoperative -0.34+/-0.38 D in Group 1, from -2.08+/-0.65 D to -0.43+/-0.64 D and from -4.42+/-0.63 D to -1.23+/-1.25 D in Group 2 and 3 respectively. We also analyzed the angle of error, magnitude of error, index of success, and coefficient of afjustment by vector analysis. No significant complications were observed during the follow-up period. These results show that PARK by excimer laser was effective in correction of astigmatism. The effect of astigmatic correction in Group 2 and 3 were better than that of Group 1. Group 1 showed overcorrected tendency and Group 2 and 3 showed undercorrected tendency.

Adenoid cystic carcinoma (ACC) of lacrimal gland is the most common epithelial neoplasms of the lacrimal gland. This highly invasive tumor disseminates hematogenously, but also infiltrates between tissue planes along nerves and blood vessels into the surrounding bone, represents low rate of the survival and difficult to cure. We experienced the case of a 41-year-old woman who had complained pain and downward displacement of the right eye. These symptoms had been occured 5 months ago. The MRI and the histopathologic findings revealed adenoid cystic carcinoma of the right lacrimal gland. We performed the lateral orbitotomy followed by macroscopical complete resection of tumors being different from radical therapy. The patient received 6.000 cGy of postoperative radiation for prevention of recurrence of tumor. While she has been treated from 9 months ago, there was no evidence of metastasis and recurrence, and we obtained good cosmetic results with our treatment modality. So we present our case with a brief review of the literature.

PURPOSE: This study investigated the effects of trunk muscle activity with power grasping during one leg stance. METHODS: Twenty-eight subjects participated in this study. Subjects were divided into two groups, one that performed power grasping, and another that did not. An investigator measured the activities of a subject's trunk muscle such as internal oblique (IO), external oblique (EO), erector spinae (ES), and gluteus medius (GM) while a subject was doing one leg stance. RESULTS: An independent t-test was used to analyze trunk muscle activities with power grasping during one leg stance between the experimental group and the control group. Only the EO activity differed significantly between groups (p<0.05). CONCLUSION: The results indicate that one leg stance with power grasping affected trunk muscle activity. Therefore, this is a useful method for providing lumbar spine stability.

Rosai-Dorfman disease (RDD) is an idiopathic histioproliferative disorder of lymph node and extranodal site. Bone involvement is very rare. We report a case of extranodal RDD of the tibia in 32-year old male. The patient presented with pain with no evidence of lymphadenopathy. Clinico-radiologic diagnosis was metastatic carcinoma or Langerhans cell histiocytosis, but, histopathologic examination confirmed the diagnosis with RDD. We performed curettage on the osteolytic lesion of tibia. In South Korea, there was no report about RDD of the extremity and we want to report this case with review of the literature.

OBJECTIVE: Patients with spontaneous intracerebral hemorrhage (ICH) presenting within 24 hours of symptom onset are known to be increased risk of hematoma expansion which is closely correlated with morbidity and mortality. We investigated whether tiny enhancing foci ('Spot sign') on axial view of 3-dimensional computed tomography angiography (3D-CTA) source images can predict subsequent hematoma expansion in spontaneous ICH. METHODS: During a 2-year period (March 2007-March 2009), we prospectively evaluated 3D-CTA of 110 patients with spontaneous ICH. Based on source images of 3D-CTA, patients were classified according to presence or absence of 'Spot sign'; 'Spot sign' (+) group, 'Spot sign' (-) group. Radiological factors and clinical outcomes were compared between two groups. RESULTS: Hematoma expansion occurred in 16 patients (15%). Mean Glasgow Coma Scale (GCS) score of patients with hematoma expansion was significantly different compared to score of patients without hematoma expansion (5 vs. 9, p < 0.001). Nineteen patients (16%) of 110 ICH patients demonstrated 'spot sign' on 3D-CTA. Among the 'spot sign' (+) group, 53% of patients developed hematoma expansion. Conversely 7% of patients without 'spot sign' demonstrated the hematoma expansion (p < 0.001). Initial volume and location of hematoma were significantly not associated with hematoma expansion except shape of hematoma. CONCLUSION: Our study showed that patients with hematoma expansion of spontaneous ICH had significant clinical deterioration. And the fact that 'spot sign' (+) group have higher risk of hematoma expansion suggests the presence of 'spot sign' on source images of 3D-CTA can give a clue to predict hematoma expansion in spontaneous ICH.

OBJECTIVE: The purpose of this study is to investigate the combined effects of ginkgo biloba extract, ginkgolide A and B and aspirin on SK-N-MC, human neuroblastoma cell viability and mRNA expression of growth associated protein43 (GAP43), Microtubule-associated protein 2 (MAP2), B-cell lymphoma2 (Bcl2) and protein53 (p53) gene in hypoxia and reperfusion condition. METHODS: SK-N-MC cells were cultured with Dulbecco's Modified Eagle's Medium (DMEM) media in 37degrees C, 5% CO2 incubator. The cells were cultured for 8 hours in non-glucose media and hypoxic condition and for 12 hours in normal media and O2 concentration. Cell survival rate was measured with Cell Counting Kit-8 (CCK-8) reagent assay. Reverse transcriptase polymerase chain reaction (RT-PCR) was used to estimate mRNA levels of GAP43, MAP2, Bcl2, and p53 genes. RESULTS: The ginkgolide A and B increased viable cell number decreased in hypoxic and reperfused condition. The co-treatment of ginkgolide B with aspirin also increased the number of viable cells, however, there was no additive effect. Although there was no increase of mRNA expression of GAP43, MAP2, and Bcl2 in SK-N-MC cells with individual treatment of ginkgolide A, B or aspirin in hypoxic and reperfused condition, the co-treatment of ginkgolide A or B with aspirin significantly increased GAP43 and Bcl2 mRNA levels. In MAP2, only the co-treatment of ginkgolide A and aspirin showed increasing effect. The mRNA expression of p53 had no change in all treating conditions. CONCLUSION: This study suggests that the combined treatments of Ginkgo biloba extracts and aspirin increase the regeneration of neuroblastoma cells injured by hypoxia and reperfusion.

OBJECTIVE: Acute cauda equina syndrome secondary to lumbar disc herniation is a rare clinical entity, but its sequelae such as bladder and sexual dysfunction are too severe to overlook. The purpose of this study is to determine the relationship between surgical timing and outcome. METHODS: Between 1994 and 1999, 43 patients(34 male and 9 female), ranging in age from 19 to 67 years(mean: 44.5), were operated due to acute cauda equina syndrome secondary to lumbar disc herniation. All presented with bladder and bowel dysfunction:36(83.7%) had motor weakness and 32(74.4%) had sensory deficit. The levels of herniations were L4/5 in 16 patients, L5/S1 in 10 and L3/4 in 5. RESULTS: The time to surgery from the onset of the symptom ranged from less than 24 hours to more than 14 days:10 patients underwent surgery within 48 hours of onset. The mean follow-up period was 54 months. In motor function recovery, there was no significant difference, but in bladder and sexual functions, there was significant difference according to the duration of symptoms before surgery. CONCLUSION: In acute cauda equina syndrome, emergency decompression surgery should be done. The outcome is good in patients operated within 48 hours compared to those treated more than 48 hours after the onset of the syndrome.
