Purpose: A brain abscess is a serious disease of the central nerve system. We conducted this study to summarize the clinical manifestations and outcomes of brain abscesses. Methods: A retrospective chart review of pediatric patients diagnosed with brain abscesses from November 1994 to June 2009 was performed at Samsung Medical Center, Seoul, Korea. Results: Twenty-five patients were included in this study. On average, 1.67 cases per year were identified and the median age was 4.3 years. The common presenting clinical manifestations were fever (18/25, 72%), seizure (12/25, 48%), altered mental status (11/25, 44%), and signs of increased intracranial pressure (9/25, 36%). A total of 14 (56%) patients had underlying illnesses, with congenital heart disease (8/25, 32%) as the most common cause. Predisposing factors were identified in 15 patients (60%). The common predisposing factors were otogenic infection (3/25, 12%) and penetrating head trauma (3/25, 12%). Causative organisms were identified in 64% of patients (16/25). The causative agents were $S$$intermedius$ (n=3), $S$$aureus$ (n=3), $S$$pneumoniae$ (n=1), Group B streptococcus (n=2), $E.$$coli$ (n=1), $P.$$aeruginosa$ (n=1), and suspected fungal infection (n=5). Seven patients received medical treatment only while the other 18 patients also required surgical intervention. The overall fatality rate was 16% and 20% of patients had neurologic sequelae. There was no statistical association between outcomes and the factors studied. Conclusion: Although uncommon, a brain abscess is a serious disease. A high level of suspicion is very important for early diagnosis and to prevent serious consequences.
Purpose: Lymphocyte subset recovery is an important factor that determines the success of hematopoietic stem cell transplantation (HSCT). Temporal differences in the recovery of lymphocyte subsets and the factors influencing this recovery are important variables that affect a patient's posttransplant immune reconstitution, and therefore require investigation. Methods: The time taken to achieve lymphocyte subset recovery and the factors influencing this recovery were investigated in 59 children who had undergone HSCT at the Department of Pediatrics, The Catholic University of Korea Seoul St. Mary's Hospital, and who had an uneventful follow-up period of at least 1 year. Analyses were carried out at 3 and 12 months post-transplant. An additional study was performed 1 month post-transplant to evaluate natural killer (NK) cell recovery. The impact of pre- and post-transplant variables, including diagnosis of Epstein-Barr virus (EBV) DNAemia posttransplant, on lymphocyte recovery was evaluated. Results: The lymphocyte subsets recovered in the following order: NK cells, cytotoxic T cells, B cells, and helper T cells. At 1 month post-transplant, acute graft-versus-host disease was found to contribute significantly to the delay of $CD16^+/56^+$ cell recovery. Younger patients showed delayed recovery of both $CD3^+/CD8^+$ and $CD19^+$ cells. EBV DNAemia had a deleterious impact on the recovery of both $CD3^+$ and $CD3^+/CD4^+$ lymphocytes at 1 year post-transplant. Conclusion: In our pediatric allogeneic HSCT cohort, helper T cells were the last subset to recover. Younger age and EBV DNAemia had a negative impact on the post-transplant recovery of T cells and B cells.

Purpose : This study was performed to investigate the epidemiology of enterovirus (EV) infections in children at a secondary hospital during recent 5 years. Methods : We collected the cerebrospinal fluid, stool and throat swab samples from the pediatric patients with suspected EV infections in KEPCO Medical Center, Seoul, Korea from July 2006 to September 2010. EV detection and genotype identification were performed by RT-PCR at Korea Centers for Disease Control and Prevention. Results : A total of 386 samples were collected from 277 patients during study period. Ninety-eight patients (35.4%) were diagnosed with EV infections. The RT-PCR positive rate was the highest in throat swab samples (48.3%). The median age of patient was 4.7 years (range, 0.1-12.5 years). Aseptic meningitis (50, 51.0%) was the most common clinical manifestation; herpangina (22, 22.4%) and hand-foot-mouth disease (18, 18.4%). One hundred EVs were isolated from 98 patients and 20 genotypes of EV were identified; Echovirus 30 (28 cases, 28%), Enterovirus 71 (12 cases, 12%), Echovirus 25 (10 cases, 10%), Echovirus 9 (9 cases, 9%) and Coxsackievirus A6 (8 cases, 8%). Aseptic meningitis caused by Echovirus 30 was the most common manifestation in 2008. There was no complicated case caused by Enterovirus 71. Conclusion : This study showed the epidemiology of confirmed EV infection in children from 2006 to 2010. There is a need for continuous surveillance of EV infections and its clinical manifestations.
Purpose: In children with acute leukemia, bone marrow genetic abnormalities (GA) have prognostic significance, and may be the basis for minimal residual disease monitoring. Since April 2007, we have used a multiplex reverse transcriptase-polymerase chain reaction tool (HemaVision) to detect of GA. Methods: In this study, we reviewed the results of HemaVision screening in 270 children with acute leukemia, newly diagnosed at The Catholic University of Korea from April 2007 to December 2011, and compared the results with those of fluorescence in situ hybridization (FISH), and G-band karyotyping. Results: Among the 270 children (153 males, 117 females), 187 acute lymphoblastic leukemia and 74 acute myeloid leukemia patients were identified. Overall, GA was detected in 230 patients (85.2%). HemaVision, FISH, and G-band karyotyping identified GA in 125 (46.3%), 126 (46.7%), and 215 patients (79.6%), respectively. TEL-AML1 (20.9%, 39/187) and AML1-ETO (27%, 20/74) were the most common GA in ALL and AML, respectively. Overall sensitivity of HemaVision was 98.4%, with false-negative results in 2 instances: 1 each for TEL-AML1 and MLL-AF4. An aggregate of diseases-specific FISH showed 100% sensitivity in detection of GA covered by HemaVision for actual probes utilized. G-band karyotype revealed GA other than those covered by HemaVison screening in 133 patients (49.3%). Except for hyperdiplody and hypodiploidy, recurrent GA as defined by the World Health Organizationthat were not screened by HemaVision, were absent in the karyotype. Conclusion: HemaVision, supported by an aggregate of FISH tests for important translocations, may allow for accurate diagnosis of GA in Korean children with acute leukemia.

Purpose: To evaluate the outcomes and prognostic factors in children with extracranial germ cell tumors (GCTs) treated at a single institution. Methods: Sixty-six children diagnosed with extracranial GCTs between 1996 and 2012 were included in the study. Primary treatment was surgical excision, followed by six cycles of cisplatin-based chemotherapy. The survival rates were compared according to the International Germ Cell Cancer Cooperative Group classification used for GCTs in adults to validate the classification guidelines for GCTs in children. Results: The median patient age was 4.4 years. In 34 patients (51.5%), the primary tumor site was the gonad. Extragonadal GCTs were detected in 32 patients. The 5-year overall survival and event-free survival (EFS) were $92.0%{\pm}3.5%$ and $90.4%{\pm}3.7%$, respectively. In univariate analysis, tumor histology, metastasis, and elevated alpha-fetoprotein were not prognostic factors in children with extracranial GCTs. However, EFS was poorer in patients with mediastinal disease (n=12, $66.7%{\pm}13.6%$) than in those with nonmediastinal disease (n=54, $96.0%{\pm}2.8%$) (P=0.001). The 5-year EFS was lower in patients older than 10 years, (n=21, $80.0%{\pm}8.9%$) compared with those younger than 10 years (n=45, $95.2%{\pm}3.3%$) (P=0.04). Multivariate analysis identified the mediastinal tumor site as the only independent prognostic factor. Conclusion: The prognosis of children with extracranial GCTs was favorable. However, nongerminomatous mediastinal tumors were associated with poor survival in children. Further research is needed to improve the prognosis of children with malignant mediastinal GCTs.
BACKGROUND/OBJECTIVES: We examined dietary fat intake and the major food sources by young children in Korea. SUBJECTS/METHODS: A total of 1,041 children aged 1-5 years were identified from the 2013-2015 Korea National Health and Nutrition Examination Survey. Data on total fat and fatty acid intake were obtained by a single 24-h dietary recall. Food sources were identified based on the amounts of total fat and fatty acids consumption according to each food. Fat and fatty acid intakes and their food sources were presented by age group (1-2-y, n = 401; 3-5-y, n = 640). Fat and fatty acid intakes were also evaluated according to socioeconomic characteristics. RESULTS: The mean intake of fat was $27.1{\pm}0.8g$ in the 1-2-y group and $35.5{\pm}0.7g$ in the 3-5-y group, and about 23% of the total energy was obtained from fat in both age groups. The mean intake of saturated fatty acids (SFA) was $10.5{\pm}0.3g$ in the 1-2-y group and $12.7{\pm}0.3g$ in the 3-5-y group, with the 1-2-y group obtaining more energy from SFA than the 3-5-y group (9.2% vs. 8.3%). The mean intake of polyunsaturated fatty acids (PUFA) was $6.3{\pm}0.1g$ in the total subjects, with $0.8{\pm}0.03g$ of n-3 fatty acids and $5.5{\pm}0.1g$ of n-6 fatty acids being consumed. Milk, pork, and eggs were major food sources of total fat, SFA, and monounsaturated fatty acids, and soybean oil was the main contributor to PUFA in both age groups. In the 1-2-y group, children in rural areas had significantly higher intake of PUFA and n-3 fatty acids than did those in urban areas. CONCLUSIONS: Our findings provide current information on dietary fat intake among young Korean children and could be used to establish dietary strategies for improvement of health status.

Purpose: To evaluate the effects of total body irradiation (TBI), as a conditioning regimen prior to allogeneic stem cell transplantation (allo-SCT), in pediatric acute leukemia patients. Materials and Methods: From January 2001 to December 2011, 28 patients, aged less than 18 years, were treated with TBI-based conditioning for allo-SCT in our institution. Of the 28 patients, 21 patients were diagnosed with acute lymphoblastic leukemia (ALL, 75%) and 7 were diagnosed with acute myeloid leukemia (AML, 25%). TBI was completed 4 days or 1 day before stem cell infusion. Patients underwent radiation therapy with bilateral parallel opposing fields and 6-MV X-rays. The Kaplan-Meier method was used to calculate survival outcomes. Results: The 2-year event-free survival and overall survival rates were 66% and 56%, respectively (71.4% and 60.0% in AML patients vs. 64.3% and 52.4% in ALL patients, respectively). Treatment related mortality rate were 25%. Acute and chronic graft-versus-host disease was a major complication; other complications included endocrine dysfunction and pulmonary complications. Common complications from TBI were nausea (89%) and cataracts (7.1%). Conclusion: The efficacy and toxicity data in this study of TBI-based conditioning to pediatric acute leukemia patients were comparable with previous studies. However, clinicians need to focus on the acute and chronic complications related to allo-SCT.
Contemporary nursing is concerned with meeting patients physical psychological and secio-economical needs and with helping persons to sore their own problems. At the time of confinement and delivery, women often have physical and psychological disco- mort related to fear, tension or anxiety. Pain related to these causes varies with the individual woman. Effective nursing care to meet individual needs during labor and delivery is important if nurses are to understand and relieve woman's physical and psychological pain. A questionnaire prepared for the purpose by the investigator was administered to 162 women in two general hospitals, one in Seoul and one in TaeGu, during August 1 and September 20, 1975 and to the 13 delivery-room nurses who cared for them. It was hoped that the study would contribute to comprehensive nursing care during labor and delivery and to improve maternal and child health. 1. The sample of mothers ranged in age from 18 to 39; the majority were from 25 to 29 years old (54.3%). Most of them were housewives (87.6%). Sixty-three percent had high school or higher education. They had a range of one to seven deliveries. Sixty-one percent were primiparas Most had some prenatal care (87.6%). 2. The age of the group of nurses ranged from 22 to 39. Ten were 22 or 23. Five of the 13 had from six to ten months experience in the de]ivory room. Twelve were single and ten had a religious affiliation. 3. Both primiparas and multiparas thought equally that physical and psychological care, nursing skills and attitudes were important during labor and delivery, but did not relate basic nursing care directly to normal delivery. Need for nursing care was rated more highly by primiparas (2.83-3.48) than by multiparas (2.51-3.17) (p〈0.05). 4. There was no difference in need for nursing care according to the educational level of the women nor according to whether they had a religious affiliation or not (p〉0.05). 5. There was no difference in the reported nursing care given regarding of the educational preparation of the nurses (p〉 0.05). 6. There the reported nursing needs of the women and the reported nursing care given were compared, physical and psychological nursing care directed toward protecting the mother and fetus and a safe do]ivory were considered important by both groups. Neither group related simple nursing care directly to protection of the mother and fetus or to a safe delivery. The women rated highly their needs for nourishment (3.05) and having a relative with them (2.90) for emotional support but there was little evidence (2.39) that the nurses provided care to meet these needs (p〈0.05). In conclusion, the nursing needs of the women during the three stages of labor and the nursing care given were generally similar. The women had more psychological needs than physical needs but in comparison, nurses gave a little more physical than psychological care. The results point up the need to make adjustments in labor and delivery room nursing care the nurse should Prepared to pay more attention and bigger consideration in psychological comfort care than physical care.

A rainbow trout uncoupling protein 3 (UCP3) cDNA clone, encoding a 310 amino acid protein, was cloned and sequenced from a liver cDNA library. Two different splice variants designated UCP3-vl and UCP3-v2, were identified through liver cDNA library screening using rainbow trout UCP3 cDNA clone as a probe. UCP3-vl has 3 insertions in the UCP3 cDNA: the first insertion (133 bp), the second (141 bp), and the third (370 bp) were located 126 bp, 334 bp and 532 bp downstream from the start codon, respectively. UCP3-v2 contained a single insertion, identical in sequence and location to the second insertion of UCP3-vl. UCP3, a mitochondrial protein, functions to modulate the efficiency of oxidative phosphorylation. UCP3 has been detected from heart, testis, spinal cord, eye, retina, colon, muscle, brown adipose tissue and white adipose tissue in mammalian animals. Human and rodent UCP3s are highly expressed in skeletal muscle and brown adipose tissue, while they show weak expression of UCP3 in heart and white adipose tissue. In contrast to mammalian studies, RT-PCR and Southern blot analysis of the rainbow trout demonstrated that UCP3 is strongly expressed in liver and heart. UCP3, UCP3-vl, and UCP3-v2 all contain an Ava III short interspersed element (SINE), located in the 3'untraslated region (UTR). PCR using primers from the Ava III SINE and the UCP3 3'UTR region indicates that the UCP3 cDNA is structurally conserved among salmonids and that these primers may be useful for salmonid species genotyping.

The purpose of this study is to investigate what owners think of their housing and their community by scrutinizing households, thereby leading to a conclusion of how these communities have developed and the advantages they provide to their owners. This study was conducted by thoroughly interviewing one member from each of a total of 10 households living in apartments and villas in the Gangnamgu area of Seoul between August 5, 2008, and September 25, 2008. The results can be summarized as follows: First, all interviewees were female, within the range of 40 years to 50 years of age, and with high educational backgrounds. They were living in mid-level income or higher households but were characterized by frugal attitudes. Second, their households held a personal and familial meaning to them, one of providing replenishment, rest, and a place to share diverse feelings with their family. Certain factors such as being a convenient place for education, rising housing prices, a large area of greenery made possible by Yangjae Cheon, and so forth contributed to giving a special significance to their housings. The interviewees all thought the convenience of education and the rising housing prices in the Gangnam area were the most important factors. Third, the interviewees indicated the following sociocultural perspectives of Gangnam housings: They provide a good environment for education due to the densely clustered academies in the Daechi-dong area. There are many opportunities to meet neighbors with similar educational and economic backgrounds. There are vast areas of greenery such as Yangjae Cheon. There is access to highly advanced cultural and shopping facilities such as COEX, Seoul Arts Center, etc. There are no amusement centers located near the housing districts. There are convenient transportation methods and facilities. They are subject to jealous looks from people living outside the Gangnam area. Lastly, it seems that no significant community spirit exists among the dwellers of each apartment or villa. However, matters of self-interest such as construction problems, which contribute greatly to creating personal wealth, were exceptions when the dwellers united as a single household.
