In a case of 46-year-old woman suffering from schizophrenia for over 20 years, she experienced frequent episodes of dyspnea and confirmed as superimposed with myasthenia gravis (MG). Throughout the seven-year follow-up period, after diagnosed as MG, she has been hospitalized 6 times and also diagnosed as colorectal cancer. Authors experienced various conditions associated with untoward effects of medication for myasthenia, schizophrenia, and colorectal cancer. Therefore, authors reported considerations for the pharmacotherapy of schizophrenia with myasthenia gravis.

OBJECTIVES: As a preliminary study on the prevalence of mental disorders in Korean children and adolescents, we investigated the diagnosis distribution of mental disorders in people under 19 years of age using the health insurance data. METHODS: From the 2011 health insurance data of 1,375,842 people, the data of 286,465 people under 19 years old were extracted. Among them, we selected 10,778 with psychiatric diagnoses; male 6,453 (59.9%) and female 4,325 (40.1%). The frequency of psychiatric diagnoses in the males was 10,140 (62.7%) cases, which was significantly higher than that (6,031; 37.3%) in the females. We categorized the groups into 3 year intervals. RESULTS: In the males under 3 years old, F80 was the most prevalent diagnosis, followed by F98. F90 and F41 were the most prevalent in the 4-15 and above 16 years old groups, respectively. In the females, F98 was the most prevalent in the children up to 3 years old, while F80 was the second most prevalent. In the 4-6 years of age group, F98 was the most prevalent, followed by F93. F90 and F41 were predominant in the 7-12 and above 12 years old groups, respectively. CONCLUSION: In the analysis of the frequency of diagnosis of mental disorders in the population under 19 years old, there were significant differences in the distribution based on age and gender.

There is a highly cognitive and social context to empathy behavior in human. In various social contexts, rodents also display remarkable affective sensitivity and exhibit primitive forms of empathy similar to human. Therefore, we aimed to elaborate the concept of empathy about various components of empathetic behavior in rodents with the similar contexts of a human. In this review, we highlighted the behavioral paradigm that already examined different aspects of rodent empathetic behavior in response to conspecific distress. Additionally, we summarized homologous brain parts of human and rodents to express the empathetic behavior. Integrating the findings with corresponding experiments in the human will provide a novel insight into therapeutic intervention or expanded experimental approaches for neuropsychiatric disorders like autism spectrum disorders associated with empathetic behavior.

OBJECTIVE: The image of the wicked stepmother has created a prejudice against stepmothers, which makes it difficult for them to adjust to their stepfamilies. This study compared fairy tales from different cultures to reestablish the nature of stepmothers.METHODS: Grimms’ Fairy Tales (GFT) was used to represent Western culture, with stepmother characters appearing in 15 out of 210 tales. “The Collection of Korean Traditional Fairy Tales” (KFT) was used to represent Eastern culture, with stepmother characters featured in 14 out of 15,107 tales. We examined the relationships between stepmothers and stepchildren in GFT and KFT.RESULTS: Daughters were abused more often than sons in both genres. In GFT, jealousy spurred the abuse in 12 of 15 cases, while in KFT greed was predominant in 12 of 14 cases.CONCLUSION: The fairy tale portrayals of wicked stepmothers may be associated with the stigma children place on their stepmothers, which needs to be overcome.

Objective: Research on neural correlates in the prefrontal cortex (PFC) associated with self-injurious behavior has mainly been performed in adults. However, studies on adolescents are scarce. We aimed to investigate the activation and connectivity of the PFC between adolescents with self-injurious behavior (ASI) and psychiatric controls (PC) using functional near-infrared spectroscopy (fNIRS). Methods: We used an emotion recognition task during fNIRS to assess 37 adolescents (23 with self-injurious behavior and 14 PC) between June 2020 and October 2021 and compared connectivity and activation between the two groups. We also measured adverse childhood events (ACE, Adverse Childhood Experiences) and performed a correlation analysis of channel activation according to ACE total scores. Results: The difference in activation between the groups was not statistically significant. The connectivity of channel 6 was statistically significant. The interaction between channel 6 and the ACE total score showed statistical significance between the two groups(t[33] -2.61; p=0.014). The ASI group showed a negative correlation with the total ACE score. Conclusion This is the first study to investigate PFC connectivity using fNIRS in ASI. It has the implication of a novel attempt with a practically useful tool to uncover neurobiological differences among Korean adolescents.

Psychological resilience in children preventing them from being overwhelmed by traumatic events and nurture their healthy development is universal and powerful. Movies about fairy tales provide children with the notion of the existence of the power and various manifestations. Even though the traumatic event affects the development of the child, with a good supporting system and by providing healthy internal and external factors to reconstruct the event, the traumatized child may accept the event objectively, develop the healthier part of the ego, and even sublimate the traumatic events. As the children participate in movies or plays, several protectors can be devised. The child prepares the role under a "promise" of virtual reality, performs the role recognizing that the traumatic event is not real, and returns to real life as the role or play ends. When these protectors are provided, it is considered that resilience can function properly and the role does not have a negative influence on the development of a child.

OBJECTIVES: 'Taegyo,' prenatal education, is steeped into Korean culture. Although there has been a traditional focus on providing education and care for the fetus in Korea, there is a lack of medical evidence for its effectiveness. METHODS: The authors assessed the scientific basis for 'Taegyo' by reviewing the evidences. RESULTS: 'Taegyo' in Korea began with the spread of Buddhist culture from China, and transmitted by word-of-mouth. The first 'Taegyo' book, the Tae-gyo-shin-gi, was published on 1803. Modern prenatal education is very diverse. However, only a few studies on its effect have been conducted. Development of medicine, especially obstetrics, fetology, pediatrics, psychiatry, and etc., has learned that many factors, including bad environmental conditions and maternal stress, influenced against the fetus and mother. As for the paternal side, occupation, smoking, and stress were also revealed to have consequences for the development of the fetus. On the contrary, adequate maternal nutrition, exercise, and music stimulation positively impact the fetal development and healthy birth. CONCLUSION: Traditional contents of 'Taegyo' were proved to have effectiveness from evidence-based medicine and animal experiments. We need further studies to explore the impact of prenatal education for the fetal development and maternal health.

OBJECTIVES: We examined the risk factors for subjective memory impairment in cognitively normal elderly. METHODS: One hundred fifty five cognitively normal elderly individuals with subjective memory impairment and 126 normal control subjects without subjective memory impairment were selected. All participants underwent clinical evaluation for dementia and clinical psychiatric disorder conformed to the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet and Korean version of Mini-International Neuropsychiatric Interview, respectively. Korean version of Geriatric Depression Scale-Revised was administered to evaluate depression. Subjective memory impairment was defined as 1) subjective memory complaint by the participant and/or the informants and 2) evidence of memory impairment. RESULTS: Depression [odds ratio (OR)=1.07, 95% confidence interval (CI)=1.03-1.10] and female (OR=2.27, 95% CI=1.17-4.39) significantly increased the risk of subjective memory impairment in cognitively normal elderly. CONCLUSION: Depression can be a risk factor of subjective memory impairment in cognitively normal elderly. The clinicians should be vigilant regarding the presence of depression when assessing the subjects with subjective memory complaint.

OBJECTIVES: This study investigated the relationship between depression, attachment and addiction problems in runaway youths. METHODS: We sent a questionnaire package to 187 runaway youths in 18 adolescent shelters. The questionnaire package collected their sociodemographic data and included the Patient Health Questionnaire-9, Inventory of Parent Attachment (IPA), Korean Internet Addiction Self-Scale (K-Scale), Korean version of Alcohol Use Disorders Identification Test, and Korean version of the Fagerström Test for Nicotine Dependence. RESULTS: The percentage of youth with depression was 28.8% (N=54). In the depression group, there were significantly more problematic alcohol users (53.06%, p=.0199) and significantly lower IPA scores (p=.0064). There was a significant negative correlation between depression and a IPA, and significant positive correlation between depression and the K-Scale. CONCLUSION: These results suggest that runaway youths with depression have more problematic alcohol drinking and attachment problems.
