PURPOSE: Successful management of epileptic patients requires complete control of seizures without adverse effect. The purpose of this study is to evaluate the hematologic effect and hepatic enzyme change of antiepileptic drugs in epileptic children and compare the changes of these values according to serum drug level. METHODS: The study included 89 epileptic children with antiepileptic drugs such as phenobarbital, valproate, and carbamazepine from May 1990 to July 1999. We classified these patients into 3 groups according to the drug they had taken; group 1 : patients treated by phenobarbital, group 2 : valproate, group 3 : carbamazepine. Baseline screening tests before the start of therapy for all patients included complete blood count(CBC) and differential, platelet count, serum alanine aminotransferase(ALT), aspartate aminotransferase(AST). The tests wee repeated at follow-up visits in 2nd week, 4th week, 6th week, 12th month on the new drug. We compared their mean hematologic and liver enzyme values, which were examined before and after taken the medications, such as white blood cell counts(WBC), red blood cell(RBC), platelets, hemoglobin(Hgb), hamatocrit(Hct), mean corpuscular volume(MCA), mean corpuscular hemoglobin(MCH), mean corpuscular hemoglobin concentration(MCHC), AST, and ALT. Statistically significant change of each value was observed according to drug blood levels. RESULTS: No significant differences were found between before and after medication on AST, ALT, Hgb, MCHC in all the groups. The WBC count diminished after medication of carbamazepine, significantly. But the correlation between WBC count and serum carbamazepine level was no statistically significant. The mean platelet count diminished significantly after medication of phenobarbital and valproate, and the correlation of maximum serum valproate level with the degree of platelets count was statistically significant. Statistically significant changes were found on MCV and MCH values before and after the medication in 3rd group. But it did not depend on carbamazepine blood level. CONCLUSION: Statistically significant correlations was found between the platelet count and the plasma valproate level. Significant increase of MCV and MCH, and decrease WBC count was observed after the medication of carbamazepine.

Stroke is a leading cause of long-term disability in ischemic survivors who are suffering from motor, cognitive, and memory impairment. Previously, we have reported suppressing LPA5 activity with its specific antagonist can attenuate acute brain injuries after ischemic stroke. However, it is unclear whether suppressing LPA5 activity can also attenuate chronic brain injuries after ischemic stroke. Here, we explored whether effects of LPA5 antagonist, TCLPA5, could persist a longer time after brain ischemic stroke using a mouse model challenged with tMCAO. TCLPA5 was administered to mice every day for 3 days, starting from the time immediately after reperfusion. TCLPA5 administration improved neurological function up to 21 days after tMCAO challenge. It also reduced brain tissue loss and cell apoptosis in mice at 21 days after tMCAO challenge. Such long-term neuroprotection of TCLPA5 was associated with enhanced neurogenesis and angiogenesis in post-ischemic brain, along with upregulated expression levels of vascular endothelial growth factor. Collectively, results of the current study indicates that suppressing LPA5 activity can provide long-term neuroprotection to mice with brain ischemic stroke.

Malignant tumors of the maxilla represent about 3-4% of head and neck malignant neoplasm and the origins are maxillary gingiva, hard palate and maxillary sinus. We are to investigate clinical features and results according to various treatment modalities of maxillary malignant tumor to get information for better treatment results. Sixty patients with malignant maxillary tumors treated at Yonsei medical center from 1992 to 1997 were studied retrospectively. They are evaluated according to clinical signs & symptoms, stages at first diagnosis, primary site, histopathologic features, treatment method, recurrence and survival rate with clinical records, biopsy results and CT radiograph. The most common primary site was maxillary sinus and most common histopathology was squamous cell carcinoma. The local recurrence rate was 18% at 5 years, neck failure was 3% and distant metastasis was 18%. Overall survival rate was 78% at 2 years and 69% at 5 years. Failure at primary site is the main problem in the curative treatment. So, to improve survival in these patients efforts should be directed toward improvement of local control.

OBJECTIVES : A neural circuit including amygdala, the hippocampal complex and prefrontal cortex was associated with deficits in facial processing in schizophrenia. These deficits have a significant impact on social functioning in schizophrenia. Both neuropsychological deficits and brain structural abnormalities in first-degree relatives of schizophrenia patients suggest that they may also have the deficit in facial information processing as genetic factors. The purpose of this study was to explore the dysfunction of facial information processing in first-degree relatives of schizophrenia patients using functional magnetic neuroimaging (fMRI). METHODS : Ten non-affected siblings of schizophrenic patients and 10 normal comparison subjects having no schizophrenic siblings underwent fMRI during the d ynamic facial change procedure consisting of presentations of facial emotion and gender discrimination stimuli. The emotion discrimination condition consisted of the presentation of 12 happy faces and 12 disgust/fear faces. The gender discrimination condition consisted of the presentation of 12 male faces and 12 female faces. Condition-specific brain activations were compared between non-affected siblings and normal comparison subjects RESULTS : The facial information processing related brain regions including fusiform gyrus, several areas of frontal, temporal, occipital, and cerebellar regions exhibited more activation during gender discrimination than emotion discrimination tasks in each group. During gender discrimination task, siblings of schizophrenic patients showed less activation in right fusiform gyrus, both middle and superior frontal gyrus, left cuneus, and left inferior frontal gyrus, compared with normal comparison subjects. CONCLUSION : Dysfunctional facial information processing, such as a deficit in gender discrimination, might be an endophenotype of schizophrenia.

PURPOSE: Most men with benign prostatic hyperplasia (BPH) have bothersome lower urinary tract symptoms (LUTS). This study aimed to investigate the safety and efficacy of high-performance system (HPS) laser photoselective vaporization of the prostate (PVP) for the treatment of BPH in men with detrusor underactivity (DU). MATERIALS AND METHODS: From March 2009, 371 patients with BPH were divided into 2 groups according to the findings of preoperative urodynamic study: 239 (64.4%) patients with bladder outlet obstruction (BOO) and 132 (35.6%) patients with bladder outlet obstruction with detrusor underactivity (BOO+DU). 120 W HPS laser PVP was performed to resolve the BOO. The perioperative data and postoperative results at 1 month and 12 months, including the International Prostate Symptom Score (IPSS), maximum urinary flow (Qmax), and postvoid residual urine (PVR) values, were evaluated. RESULTS: Compared with the preoperative parameters, significant improvements in IPSS, Qmax, and PVR were observed in each group at 1 and 12 months after the operation. In addition, IPSS, Qmax, and PVR were not significantly different between the BOO and BOO+DU groups at 1 and 12 months after the operation. CONCLUSIONS: Surgery to relieve BOO in the patients with BPH seems to be an appropriate treatment modality regardless of the existence of DU.

PURPOSE: Nonarteritic anterior ischemic optic neuropathy (NAION) is believed to result from inadequate blood supply to the posterior ciliary arteries. To date, NAION in a patient with acute angle-closure glaucoma (AACG) has been reported in only two studies in the English literature. Thus, the authors report a case of NAION following AACG in a Korean patient. CASE SUMMARY: A 59-year-old woman presented with a three-day history of acute ocular pain and decreased vision in her right eye; visual acuity was hand movement and the intraocular pressure (IOP) was 66 mm Hg in the right eye. Slit-lamp examination of the patient's right eye revealed diffuse corneal edema, shallow anterior chamber, and mid-dilated pupil. Gonioscopy revealed a grade 0 angle in the right eye, and a relative afferent pupillary defect was noted. Fundus photography showed disc hemorrhage and swelling of the optic disc. Fluorescein angiography demonstrated hyperfluorescence of the optic disc due to leakage. Visual evoked potential of the right eye at the initial visit showed a decreased amplitude of P100 compared with that of the left eye. A diagnosis of NAION following AACG was made. Laser iridotomy was successfully performed to the right eye. Two months later, IOP decreased from 66 to 21 mm Hg. However, visual acuity remained as hand movement and fundus examination revealed a pale optic disc. CONCLUSIONS: NAION following AACG may be attributed to an acute IOP rise with resultant perfusion pressure decrease in the vessels which supply the optic nerve. The result obtained from the patient in the present study indicates that evaluation for NAION should be considered in AACG cases.

PURPOSE: To report a case of orbital aspergillosis with third nerve palsy. CASE SUMMARY: A 75-year-old male presented with abrupt onset of visual impairment, extraocular movement limitation, and ptosis. The patient previously experienced rhinolalia and headache and was diagnosed with sinusitis 2 months prior, and was treated with oral antibiotics for 1 week. Orbital magnetic resonance imaging revealed a mass with bone erosion including the nasal cavity, ethmoid bone, and left orbit suggestive of fugal sinusitis. Aspergillus was detected histopathologically in the mass which was removed by endoscopic surgery. Amphotericin B was administered intravenously for 7 days along with voriconazole. There was no recurrence during the follow-up period. Extraocular movement limitations and ptosis were recovered postoperatively. CONCLUSIONS: The present study results indicate that visual impairment and third nerve palsy can develop in a patient with orbital aspergillosis.

Tuberous sclerosis is a rare multisystem syndrome characterized by hamartomatous tumors of the brain, skin, viscera, and eye. The diagnostic triad for this disease, proposed by Vogt, included epilepsy, mental retardation, and adenoma sebaceum. In eyes, retinal hamartomas and optic nerve phacoma are observed over 50% and hypopigmented areas of peripheral retina and iris are often found. We introduce an 18-year old girl with adenoma sebaceum of the face, history of epilepsy and insignificant mental retardation status. She also had a retinal hamartoma in her right eye, optic nerve phacoma in her left eye, shagreen patch on lumbosacral area, angiomyolipoma of both kidneys, periventricular subependymal nodules and calcified cortical nodule of occipital lobe of brain.
