Purpose:
This study aims to explore mothers’ experiences of anger while raising a child in South Korea based on a qualitative descriptive approach.
Methods:
A total of ten mothers of children aged 1-3 years participated in the study. In-depth individual interviews were conducted from August to September 2019 to collect data, which were then subjected to thematic analysis.
Results:
A total of 4 main themes and 10 subthemes were identified. The 4 themes were “individual and environmental factors that influence anger,” “a vicious cycle of anger expression and guilt,” “being a little bit more mature as a mother,” and “need for anger management.” This study described various causes, ways of expressing, and effects of anger, as well as the mother’s coping strategies. These experiences were viewed as milestones along the journey to becoming a real parent and helped mothers develop empathy for other children and mothers. The participants expressed support for expanding the social support system for child-rearing and providing psychological programs for mothers.
Conclusion
Mothers of children aged 1-3 years experienced anger owing to various factors, but adapted by developing coping skills. This study recommends family-based support interventions to help mothers manage their emotions and parenting roles.

Spinal neurenteric cyst results from the persistence of an abnormal communication between endodermal and neuroectodermal layer. It is a rare malformation that lead to spinal cord compression. The patient is a 22-month-old boy with sudden, progressive left side motor weakness. Preoperative magnetic resonance image revealed intradural extramedullary cyst in C4-C5 level that compressed the spinal cord on the left side. After the resection of the cyst, motor weakness of the left side was partially improved, and his motor power was completely recovered after rehabilitation. Histologic examination revealed a ciliated columnar epithelial neurenteric cyst. The pre- and postoperative clinical features of the case of neurenteric cyst is described with the review of literature.

Background:
Dental caries in preschool children can cause early loss of teeth, reduced masticatory function, malocclusion, and speech disorders, making oral care for preschool children essential. However, because children have a poor ability to perform oral hygiene by themselves, educational tools that help establish correct oral health behaviors are required. This study evaluated the effect of toothbrushing application for kids on dental plaque removal and toothbrushing interest in preschool children.
Methods:
Seven 5-year-old children enrolled in a daycare center participated in the evaluation, and the same children participated in the experiment twice a week. The Pokémon Smile application (App) was used as an auxiliary application for tooth brushing, and the degree of dental plaque removal on the tooth surface was evaluated by quantitative light-induced fluorescence-digital imaging. After the experiment, children’s toothbrushing preferences were investigated through interviews.
Results:
The levels of AREA R30 and AREA R70 measured after the children’s toothbrushing as usual decreased compared to those before toothbrushing; however, the change was not significant. The levels of AREA R30 and AREA R70 measured after using the Pokémon Smile App were significantly reduced compared to those before toothbrushing. Children’s interest in brushing their teeth increased by 28.59% after using the Pokémon Smile App.
Conclusion
The toothbrushing application for kids effectively removes dental plaque by helping preschool children brush their teeth. It also increased preschool children’s interest in tooth brushing. Therefore, an oral health education application would be useful for children who need to develop correct oral care methods and habits.

PURPOSE: Duchenne/Becker muscular dystrophy(DMD/BMD) is an X-linked recessive disorder caused by mutations of dystrophin genes. The purpose of the present study is to determine the frequency and the patterns of dystrophin gene deletions and to investigate the correlation of genotypes and phenotypes. METHODS: There were included a total of 89 children(88 boys and 1 girl) diagnosed as DMD/BMD by immunohistochemistry and/or genetic analysis from 1999 to 2003 at Seoul National University Children's Hospital. We analyzed the genomic DNA by multiplex PCR using a 26 dystrophin exon primer set. Direct sequencing was performed on 23 exons(in which point mutations were detected in other previous reports) in 22 patients without deletions. Phenotype and genotype relationship analysis was performed on the basis of retrospective clinical reviews. RESULTS: The frequency of dysmorphin gene deletions was 54%(32/59), which is lower than that of European and American data. Exon deletions were detected in 59 cases and the deletion "hot spots" were exon 44-54 constituting 80% of all deletions. In 6 cases without detectable deletions, 6 point mutaions(3 nonsense mutations and 3 nucleotide variants) were detected. The patients whose deletions were in the central parts or the patients with multiple exon deletions tended to show earlier symptom onsets and more rapid progressions of weakness but there were no statistical significances. CONCLUSION: Since deletions in dystrophin genes were detected in about 50% of the patients, studies on dystrophin protein expressions using muscle biopsy samples must be done for correct diagnosis.

Journal of the Korean Child Neurology Society 2004;12(1):12-20
PURPOSE: Ketogenic diet(KD) is an alternative treatment for children with intractable seizures. This study was performed to evaluate the efficacy and tolerability of ketogenic diet METHODS: A retrospective study was performed for 57 patients(31 males, and 25 females), who were enrolled in a ketogenic diet program from 1998 to 2003 in Seoul National University Children's Hospital. We investigated the overall efficacy, influencing factors such as age at diet onset, seizure type, initial fasting, adverse events and reasons for discontinuing the diet. RESULTS: The patients mean age at diet onset was 3.5 years old. They had 3.14 medications on average at the diet initiation. One month after the diet initiation, 49 of 57(86 %) remained on KD, with 37(64.9%) having more than 50% seizure reduction rates. At 6 months, half of the patients remained on KD, with 14(28%) seizure free and 22(44%) having more than 50% seizure reduction rates. At 12 months, 15 patients(34.9%) remained on KD, with 14(32.6%) having more than 90% seizure reduction rates. Seizure types, initial fasting and age at diet onset were not statistically related to the outcomes. There were a few complications during the diet. The most common reasons for discontinuing KD were ineffectiveness and poor tolerability. CONCLUSION: Ketogenic diet appears to be a relatively effective and safe treatment option for children with intractable epilepsies.

Journal of Korean Neuropsychiatric Association 1999;38(6):1502-1510
OBJECTIVES: There is now some evidence that, in humans, psychological stress may affect immune and neuroendocrine system. In stress response, cytokines are known to orchestrate the cellular interaction of immune system and act as a major messenger in a communication with CNS. Specifically, IL1beta has been reported to be colsely related with stress induced behavior change, such as depression. Accordingly, we assessed cytokine production by peripheral blood mononuclear cells (PBMC) before and after an academic examination in 45 healthy medical students. Furthermore the possibility that IL1beta TaqI polymorphism may be associated with stress response of IL1beta production was investigated. METHODS: Blood samples were collected on the day of examination and at the second week after examination. For cytokine assay seperated PBMC were incubated for 3 days at 37 degrees C, 5% CO2. DNA was prepared by Ficoll-paque method and polymorphic region was amplified by PCR. After TaqI restriction, products were seperated by 15% polyacrylamide gel electrophoresis. RESULTS: IL1beta production and stress score were significantly higher on the examination day. The change of stress score was significantly correlated with the change of IL1beta production. However, the frequency of allele A2 was too low that the significance of genetic association could not be properly estimated. CONCLUSION: This study reports that psychological stress is accompanied by an increased production of IL1 beta with significant correlation.

Torsion of the fallopian tube is an uncommon cause for acute low abdominal pain in female that is difficult to diagnose. Because it has no pathognomonic clinical symptoms or laboratory findings, a high index of suspicion is important when there is history of pelvic pathologic conditions or surgery. The early diagnosis and surgical treatment of the disease are mandatory to preserve oviduct.
