OBJECTIVES: The aim of this study was to examine the effects of maternal sociodemographic characteristics, especially education and employment, and parenting stress on the child's self-concept. Attention was also paid to the mediating impact of parenting style on the relationship between the maternal variables and a child's self-concept. METHODS: A questionnaire and three scales were completed by fifth graders and their mothers, and 270 sets of paired data were analyzed. RESULTS: The results showed that mothers with higher education experienced less child-related parenting stress, were perceived to be more achievement-oriented and rational by their children, and also had children with more positive selfconcept. The relationship between maternal education and child's self-concept was mediated by the rationality dimension of parenting style. Maternal employment was not related to parenting stress, parenting style and most aspects of the child's self-concept. Lastly, child-related parenting stress had a negative effect on the child's self-concept, and this effect was mediated by the warmth and rationality dimensions of parenting style. CONCLUSION: Parenting style had a mediating effect on the relationships between the child's self-concept and maternal education and child-related parenting stress.

The purpose of this study was to evaluate the relationship between sella turcica morphology and delayed dental age. In total, 389 participants under 16 years old were selected. Dental age was evaluated by the Demirjian method and age discrepancy (AD), the value subtracted from dental age to chronological age, was calculated. The participants were divided into 8 groups based on the sella turcica type. Bridging ratio (BR) was defined as interclinoid distance divided by sella turcica length to determine the degree of sella turcica bridging (STB) and the participants were classified into 4 groups by BR. The data were statistically analyzed using the Kruskal Wallis test and the Mann Whitney test. Some groups with sella turcica abnormality showed lower AD than that of the normal group and the AD differences varied from 4 months to 1.3 year. As the STB severity increased, AD decreased. AD differences varied from 7 months to 1.19 year. No distinct differences were observed in sella turcica type and STB groups according to sex. The results indicate that sella turcica morphology is associated with delayed dental age. Sella turcica can be used as a supplementary indicator to predict dental development.

Purpose: Hyperdontia is a developmental disorder of the oral cavity. Mesiodens refers to the hyperdontia located between the maxillary central incisors. During the surgical procedure, the anesthetic method for pain control should be considered along with factors related to the surgery itself. The purpose of this study was to evaluate the effect of the impacted position of the mesiodens on the selection of sedation method and to suggest incisive foramen as a brief reference. Materials and Methods: This study included 126 patients who were scheduled for extraction of mesiodens. The selection criteria included patients with one palatally impacted inverted mesiodens accessible from the palatal gingival margin, and those with good cooperation potential in order to control for clinical information. Using cone beam computed tomography, vertical, horizontal, and palatal positional factors were measured, and the anesthetic method was determined by two examiners. The patients were grouped into vertical and horizontal groups based on the position of the incisive foramen. Data were statistically analyzed using the Mann–Whitney test, the chi-square test, and logistic regression analysis.Result: All positional factors differed between the outpatient and inpatient anesthetic groups. The vertical minimum distance from the alveolar ridge to the mesiodens (Va) and the minimum distance from the palatal surface to the crown tip of the mesiodens (Tc) were factors affecting the choice of anesthetic method. The distribution of the vertical and horizontal positional groups differed between the outpatient and inpatient anesthetic groups. Conclusion The incisive foramen can be used as a brief reference to determine the appropriate anesthetic method.Referral for inpatient anesthesia may be a priority if they are in the V 2 H 2 group with Va ≥5 mm, and Tc ≥6 mm, and outpatient sedation may be considered if they are in the V 1 H 1 group with Va ≤1.5 mm, and Tc ≤2.5 mm.

Purpose: To evaluate the outcomes of wavefront-optimized (WFO) and topography-guided (TG) transepithelial photorefractive keratectomy (transPRK) in the treatment of myopia and myopic astigmatism. Methods: Patients who underwent transPRK using the WaveLight EX500 excimer laser for the correction of myopia and myopic astigmatism between January 2022 and March 2023 were divided into groups of WFO transPRK (77 eyes of 36 patients) or TG transPRK (63 eyes of 31 patients) in this retrospective, observational cohort study. The preoperative and postoperative 3-month refractive and visual outcomes of the two groups were analyzed. Results: In both groups, the uncorrected distance visual acuity was 0.0 logarithm of the minimum angle of resolution or better in 95% of eyes 3 months postoperatively, and the mean manifest refraction spherical equivalent was within ±1.0 diopter in 90% of eyes. No significant differences were observed between the groups in terms of the uncorrected distance visual acuity or astigmatism. A significant induction of higher order aberrations (HOAs) was observed in both groups. However, the induction of total corneal HOAs (p = 0.014) and spherical aberrations (p < 0.001) was significantly lower in the TG group than that in the WFO group. Conclusions WFO and TG transPRK effectively improved the visual and refractive outcomes; however, the induction of total corneal HOAs and spherical aberration was lesser following the TG ablation.

PURPOSE: The purpose of this study was to identify effects of fatigue, depression and anxiety on quality of life in pregnant women with preterm labor. METHODS: With a survey design, data were collected from 138 mothers who were admitted at a hospital in Seoul, between June 2014 and September 2015. Instruments used to collect the data for the study were: Fatigue Continuum Form, Depression anxiety stress scale (DASS-21) and maternal postpartum quality of life (MAPP-QOL). RESULTS: The mean fatigue score was 68.30 with 50.7% of women being depressed and 79.7% of the 138 women being anxious. The mean quality of life was 18.92 with quality of life being associated with fatigue, depression and anxiety. Depression and fatigue explained 26% of the variance in quality of life. CONCLUSION: Depression and fatigue adversely affected women's quality of life. It is important to address appropriate management of depression and fatigue in order to improve quality of life in pregnant women with preterm labor.

Chorea hyperglycemia basal ganglia (CHBG) syndrome is an uncommon manifestation of diabetes seen in patients with poor glycemic control. It is characterized by sudden onset of chorea with characteristic hyperintensities of the basal ganglia on brain magnetic resonance imaging. We report a case of a 31-year-old female patient with a history of type 1 diabetes mellitus, renal failure, and hypertension, who presented with acute symptoms of chorea involving both the upper and lower limbs with facial and cervical dystonia. Magnetic resonance imaging revealed bilateral hyperintensities of the globus pallidus and putamen. Control of blood glucose levels led to resolution of the choreic movements. In addition, follow-up magnetic resonance imaging studies revealed improvement in the hyperintensities of the basal ganglia bilaterally.

Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is an inflammatory central nervous system disease that is driven by antibodies of the immunoglobulin G1 class.MOGAD has recently been recognized as an autoimmune disease; therefore, little is known about its rehabilitation. Here, we present a case of MOGAD that showed significant recovery after rehabilitation. A 58-year-old woman developed weakness in all extremities, dysarthria, and dysphagia. She visited the neurology department, and early brain and spine magnetic resonance imaging showed multifocal high intensity in the subcortical and periventricular white matter and the cervical cord. The patient's serum tested positive for anti-MOG antibodies. She was diagnosed with MOGAD and received intravenous steroid pulse therapy. After pharmacologic therapy, the patient was transferred to the rehabilitation department. Initially, her Functional Independence Measure (FIM) motor score was 26, allowing her to stand independently for only a few seconds. After 5 weeks of rehabilitation involving physical therapy, occupational therapy, and balance training, her FIM motor score improved to 60. However, 4 months after discharge, the disease relapsed with symptoms of motor weakness in all extremities, and steroid treatment was initiated. On the second admission, her FIM motor score was 42, but after continuous multidisciplinary rehabilitation, it improved to 76. Computerized cognitive therapy improved her cognitive function, from a Korean version of the Mini-Mental State Examination score of 23 on the first admission to 30 on final discharge. Since MOGAD is a relapsing disease, a favorable outcome can be achieved with continuous monitoring and multidisciplinary, symptom-specific rehabilitation.

Purpose: Osteogenesis imperfecta (OI) is a rare bone fragility disorder caused by defects in type 1 collagen biosynthesis. This study investigated the genotype-phenotype correlations and the efficacy of pamidronate therapy in patients with OI in a single academic center. Methods: This study included 24 patients with OI. A clinical scoring system was used to evaluate disorder severity. COL1A1 and COL1A2 genes were analyzed in 13 patients using Sanger sequencing. Genotype-phenotype correlations and the efficacy of pamidronate therapy were analyzed through a retrospective medical chart review. Results: Of the 24 patients, 18 (75%) were classified as type I (12 with type Ia and 6 with type Ib), 2 as type III (8.4%), and 4 as type IV (16.7%). Type Ia patients showed relatively higher lumbar bone mineral density (BMD) standard deviation scores (SDS) and lower clinical scores than those with other types. Seven patients with qualitative mutations had lower lumbar BMD-SDS (P=0.015) and higher clinical scores (P=0.008) than 6 patients with quantitative mutations. The annual fracture frequency and lumbar BMD-SDS improved in patients with qualitative mutations after pamidronate treatment. Conclusion This study demonstrated that OI patients with qualitative mutations in COL1A1/2 had a more severe phenotype than those with quantitative mutations. Patients with qualitative mutations showed a significant reduction in fracture frequency and an increase in lumbar BMD-SDS after pamidronate treatment. Clinical score and genotype might be helpful for predicting phenotype and response to pamidronate therapy in OI patients.

Objectives: Early pharmacologic intervention is considered necessary for improving the prognosis in patients with first-episode schizophrenia (FES). However, few nationwide population-based studies have focused on early medication adherence. We investigated the status of early adherence to antipsychotics and the effect of early adherence on later clinical outcomes in FES. Methods: We used data from the South Korean Health Insurance Review Agency database (2009-2021). We selected 28,931 patients with FES who had a prescription record of at least one antipsychotic medication within 180 days after their diagnosis. We measured early medication adherence using the medication possession ratio (MPR) and compared demographic characteristics and results of psychiatric hospitalization between the adherence group (0.6≤MPR<1.1) and the non-adherence group (MPR<0.6). Results: The average early medication adherence was 0.82 by MPR, and the non-adherence group accounted for 15.6% of all subjects. From 1 to 2 years after diagnosis, the adherence group showed a higher number of psychiatric hospitalizations per hospitalized patient but a shorter duration than the non-adherence group. Additionally, the proportion of patients who experienced psychiatric hospitalizations was smaller in the adherence group. Conclusion In patients with FES, early medication adherence is associated with lower rates of psychiatric hospitalization and shorter hospitalization durations.
