Purpose : Anticonvulsants have a number of side effects and some of them may be attributed to a disturbance of serum trace metal homeostasis. Although they are minor building components in tissues, they play important functional roles in the peripheral and central nervous system. We measured serum copper and zinc levels in epileptic children who were treated with anticonvulsants to know the effects of anticonvulsants on serum copper and zinc levels. Methods : Serum copper and zinc levels were determined in 64 epileptic patients receiving anticonvulsant therapy in Chungnam National University Hospital, and in 20 normal controls. Sixty-four epileptic patients were divided into three groups : 16 patients who were treated with valproic acid monotherapy; 26 patients who were treated with valproic acid in addition to other anticonvulsants; and 22 patients who were treated with anticonvulsants except for valporic acid. Results : All patients receiving anticonvulsants had significantly lower serum copper levels($80.21{\pm}19.42{\mu}g/dL$) in comparison to the normal controls($102.12{\pm}32.8{\mu}g/dL$). Serum zinc levels in patients receiving anticonvulsants($79.78{\pm}21.88{\mu}g/dL$) were not statistically different from those of controls ($85.26{\pm}29.81{\mu}g/dL$). There were no significant difference of serum copper and zinc levels among the three groups. Conclusion : In this study, we clearly showed that anticonvulsants decreased serum copper levels. Although we did not observe any clinical findings related to copper deficiency, we should pay attention to potent copper deficiency in patients with anticonvulsant treatment.

Purpose : p16 gene, mapped to the 9p21 chromosomal region, has emerged as a candidate tumor suppressor gene in human neoplasm. It is an inhibitor of cyclin-dependent kinase and inhibits Rb phosphorylation. In a variety of tumors including childhood acute lymphoblastic leukemia (ALL), deletion and/or mutation of the p16 gene has been found. Despite their high frequency, the prognostic importance of p16 alterations is still controversial in ALL and has been reported to be either unfavorable or similar to that of other patients. We studied the correlation between loss of p16 protein confirmed by immunohistochemical staining and clinical outcomes of patients diagnosed as ALL. Methods : We performed an immunohistochemical staining for p16 protein in 74 cases of bone marrow biopsy slide initially diagnosed as ALL between January 1998 and December 2006. We reviewed the clinical manifestations, laboratory findings, treatment outcomes retrospectively. Results : Of 74 slides, 12 were negative for p16 protein. Seven were males and 5 were females with a median age at diagnosis was 5.8 (1.3-18.8) years. Initial WBC were 17,225 $(500-403,300)/{\mu}L$. By immunologic surface marker analysis, 7 patients were early pre-B CALLA (+) and 5 patients were T-cell ALL. Two patients of intermediate risk group had relapsed and died. Three patients had family history of breast cancer. Four patients died and overall survival rates were $53.5{\pm}18.7%$. Conclusion : Loss of p16 protein is supposed to be an independent risk factor of childhood ALL associated with poor outcomes. In clinical setting, the clinician must take into account p16 status, not only at the genomic but also at the protein level. Further clinical experience on thoroughly investigated cases will help a better understanding between p16 status and clinical outcomes.
Purpose : Radiotherapy is effective in local treatment for retinoblastoma. However, asymmetric facial hypoplasia after radiation is a serious late effect. This study was performed to investigate the effects of enucleation and chemotherapy with or without radiotherapy in advanced intraocular and intraorbital retinoblastoma. Methods : Between 1985 October and 2006 December, the records of thirty five patients who were diagnosed as retinoblastoma at Yeungnam University Hospital were reviewed. Advanced intraocular and intraorbital retinoblastoma patients classified as Reese-Ellsworth group III, IV, and V and Grabowski- Abramson class II were selected for the study. Results : Eighteen patients were enrolled in this study. All patients were enucleated and had received chemotherapy. Nine patients received radiotherapy and nine patients didn't receive radiotherapy. Tumor cells were found on resection margin of optic nerve in five of nine patients who received radiotherapy, but none of nine who didn't receive radiotherapy. Chemotherapy included vincristine, adriamycin, cyclophosphamide, VM-26, cisplatin before 2001, and vincristine, etoposide, and carboplatin after 2001. There were no recurrences or metastases in nine patients who didn't receive radiotherapy. But two of nine patients who received radiotherapy had metastases to brain. However, all survivors who received radiotherapy had significant facial asymmetry. Conclusion : In advanced intraocular and intraorbital retinoblastoma without tumor cell on resection margin of optic nerve, enucleation and chemotherapy without local radiotherapy appears to be safe for long-term survival. However, in those with tumor cells on resection margin of optic nerve, enucleation and chemotherapy with local radiotherapy seems to be necessary to improve survival.
Background and purpose : Patients with acute leukemia experience prolonged periods of neutropenia due to their disease or its treatment. For this reason, they often develop serious infectious complications. Although antibiotic therapy has improved in recent years, the fatality rate from infection remains high. For the control of infection, protected environment was developed. But because of economic issue, most of chemotherapy with acute myeloid leukemia have conducted in non-protected environment. So this study compared the rate of complete remission, days with neutropenia, rate of fever, rate of positive culture, rate of overt infection and use of antibacterial and antifungal agents with patients within non-protected environment and protected environment, retrospectively, Patients with acute myeloid leukemia during first remission induction chemotherapy were eligible for this study, Methods : Retrospective analysis was conducted between patients in non-protected (25 patients) and protected environment (14 patients) with acute myeloid leukemia during remission induction chemotherapy Results : Rate of overt infection, rate of fever, rate of positive culture and rate of use of antibiotics were significantly high in patients within non-protected environment compared with patients within protected environment. There were no differences in rate of complete remission and days of neutropenia Conclusions : This study suggests protected environment for patients with acute myeloid leukemia during remission induction chemotherapy could reduce rate of overt infection, and rate of use of antibiotics.
Slipped capital femoral epiphysis(SCFE) is a disorder in which there is a gradual or acute disruption through the capital physeal plate. The physiolysis is through a widened zone of hypertrophy, which is weakened due to altered chondrocytic maturation and endochondral ossification. The cause or causes of SCFE remain uncertain. The association of obesity and adolescent age with growth rate are predisposing factors. The possibility that most patients with subclinical hormonal abnormality were proved. The goal of treatment of slipped capital femoral epiphysis is to restore the function of the hip and delay the development of degenerative osteoarthrosis by prevention of additional displacement of the epiphysis. We report 10 patients(12hips) with SCFE who were treated by surgical means and followed along for more than one year, at Yeungnam University Hospital, from 1989 to 1996. There were six boys and four girls. The average age at operation was 11.8 years. Seven cases occurred in the left hip, one case in the right and 2 cases had bilateral involvement, five cases had a history of minor trauma on affected hip. Among hormonally studied six patients, panhypopituitarism patient was one case; decreased testosterone, two; decreased growth hormone, two; and decreased thyroid hormone, one. According to clinical stage, two cases were the acute type; five cases, acute on chronic type; and three cases, chronic type. On the radiological grades of slipping, mild slippage were nine hips; moderate, one; and severe, two. The eleven hips were treated by pin fixation in situ, and one, by cuneiform osteotomy. On the average follow-up of 2.6 years, ten hips were excellent or good functional results, two hips were failure.
Dual Energy X-ray Absorptiometry(DEXA) is commonly used to diagnose Osteoporosis. The errors of DEXA bone density operation are caused by operator, bone mineral density meter, blood testing, patient. We focus on operator error then study about how much influence operator's region of intest(ROI) in bone testing result. During from March to July in 2011. 50 patients ware selected respectively from 30, 40, 50, 60, and 70 age groups who came to Korea University Medical Center(KUMC) for their Osteoporosis treatment. A-test was performed with usually ROI and B-test was performed with most widely ROI. Then, We compare A-test and B-test for find maximum difference of T-score error which occurred operator ROI controlling. Standard deviation of T-score of B-test showed 0.1 higher then A-test in femur neck. Standard deviation of B-test showed 0.2 higher then A-test in Ward's area which in Greater trocanter and Inter trocanter. Standard deviation of B-test showed 0,1 lower then A-test in L-1. Bone density testing about Two hundred patients results are as follow. When operator ROI was changed wider than normal ROI, bone density of femur was measured more higher but bone density of L-spine was measured more lower then normal bone density. That means, sometime DEXA bone density testing result is dependent by operator ROI controlling. This is relevant with the patient's medicine and health insurance, thus, tester always keep the size of ROI for to prevent any problem in the patient.

The purpose of this study is to find the relationship between lumber Herniated Nuclesus Pulposus of specific part and fat infiltration in paraspinal muscle. Also we intended to find the relationship between Body Mass Index(BMI) and fat infiltration ratio in the lumber paraspinal muscle based on the sexes of patients. We conducted this study of patients who visited our hospital from May, 2010 to May, 2012. The subjects are composed of 40 patients(20 females and 20 males), who are 30 to 50 years old suffering from severe lumber herniated nuclesus pulposus, who had or were going to have operation treatment. BMI is measured through anthropometry of each patient and fat infiltration inside the muscle is estimated by measuring the cross section area of lumbar paraspinal muscle from mid-cross section of disc(L2-S1) and fat infiltration ratio. The data of this study are analyzed by independent t-test to figure out the difference of fat infiltration between male and female, and by paired sample T-test after getting mean and standard deviation to find the changes of fat infiltration of lumbar on each level. Also correlation analysis is done by setting age as a control variable to find the correlation between BMI and fat infiltration of the whole lumbar. As a result, we could get only the meaningful difference between the sexes on upper lumber part(L2-L3) while we couldn't find any significant difference in the rest of lumbar(L3-S1). Besides, the changes of fat infiltration ratio on each lumbar level increased rapidly from lumbar 3,4 to lumbar 4,5. We also found that there is no correlation between fat infiltration ratio of lumbar paraspinal muscle(L2-S1) and BMI.
Objective: The purpose of this study was to investigate the changes in dentofacial morphology of non-orthodontically treated female patients with TMJ disk displacement. Methods: The sample consisted of 25 Korean female patients with bilateral TMJ disk displacement who visited the Department of Orthodontics, Seoul National University Dental Hospital from 1996 to 2006. Disk displacements were diagnosed using the magnetic resonance imaging (MRI) of both TMJs. Baseline (T1) and follow-up (T2) lateral cephalograms were analyzed. The mean age of samples at T1 was $18.1{\pm}3.5$ years (range 14.2 - 25.8 years) and at T2, $21.1{\pm}3.5$ years (range 16.2 - 28.0 years). The mean observation period was $3.0{\pm}1.9$ years. Descriptive statistics for each variable were calculated at baseline (T1) and follow-up (T2) stages, and during the observation period (T2-T1). Results: Skeletal changes were found in 64% of the non-orthodontically treated female patients with TMJ disk displacement during the observation period. The L1 to Mandibular plane distance (mm) increased significantly by 0.8 mm (p < 0.01). But there were no significant differences in the other dental relationship variables (overjet, overbite, U1 to palatal plane) during the observation period. Most patients with skeletal changes showed a backward rotation of the mandible. The ratio of the rotation was a decrease of SNB by $0.43^{\circ}$ for every $1^{\circ}$ increase of FMA (Spearman rho = -0.660, P < 0.01). A few patients showed a distal shift of the mandible without rotation or significant changes in the vertical dimension. Conclusions: During observation periods without orthodontic treatment, non-growing patients with TMJ disk displacement showed dentoskeletal changes, mainly backward rotation of the mandible.
This study, by grasping the degree of anxiety of Korean mothers and multicultural family mothers because of their hospitalized children, was aimed to arrange the basic data for developing the program to help the mothers of Korea and multicultural family reduce the anxiety happening due to the hospitalization of their children and adapt to their environment. Methods: The subjects of the study were a total of 200 people composed of 100 multicultural family mothers, and 100 Korean mothers respectively whose children were hospitalized in the pediatric department of K university hospital located in Daejeon City. And the period of data collection was from Aug 1, 2010 to Aug 31, 2010.As a study tool, the measuring tool of Kim Jeong Taek(1978), which STAI of Sielberger(1972) was adapted to Koreans, was used.The collected data was analyzed using SPSS WIN 12.0. Results. A result of the state anxiety of the Korean mothers with that of the multicultural family mothers of the inpatient children, Korean mothers 2.11, multicultural family mothers 2.17, result of temperament anxiety showed Korean mothers 2.09, multicultural family mothers 1.94. As a result of comparing the anxiety of the Korean mothers with that of the multicultural family mothers of the inpatient children, there was no difference between groups in both temperament anxiety and state anxiety. In a situation of anxiety, when there was no explanation of the treatment or therapy, both Korean mothers and multicultural family mothers showed the severe anxiety. In the degree of anxiety according to the general characteristics of the mothers of the inpatient children, there was not a statistically significant result in anxiety according to general characteristics of the inpatient children of korean family mothers, there was a significant difference in state anxiety according to the state of average monthly income in Korean mothers(P<.05), however, there was a significant one in temperament anxiety in the course of perceiving a test method in multicultural family mothers(P<.05). In the degree of anxiety according to the general characteristics of the mothers of the inpatient children, there was a significant difference in state anxiety according to the state of average monthly income in Korean mothers(P<.05), however, there was a significant one in temperament anxiety in the course of perceiving a test method in multicultural family mothers(P<.05). Conclusion: Through the results of the study above, no matter what socio-demographic characteristics of the mothers of the inpatient children are, regardless of the general characteristics of the inpatient children, it was found out that most of mothers felt anxiety.
