State and Trait Anxiety of Adolescents with Autism Spectrum Disorders

Objective@#This study examined how state and trait anxiety of adolescents with autism spectrum disorders (ASD) are associated with their demographic characteristics, repetitive and restricted behaviors (RRBs), and internalizing and externalizing problem behaviors. @*Methods@#A total of 96 participants with ASD (mean age=14.30 years; 91 males) completed a battery of tests including the State/Trait Anxiety Inventory (STAI), the Autism Diagnostic Interview-Revised, the Social Responsiveness Scale (SRS), and a cognitive test measuring intelligence quotient (IQ). Participants’ parents completed the Child Behavior Checklist (CBCL). Pearson’s correlations among age, IQ, two subscales of the STAI (i.e., STAIS and STAIT, measuring self-reported state and trait anxiety, respectively), and the Anxiety subscale of CBCL (i.e., CBCL-Anxiety, measuring parent-reported trait anxiety) were computed. Subsequently, Pearson’s correlations were computed among the three anxiety measures, RRBs, and problem behaviors, while controlling for participants’ age and IQ. @*Results@#The STAIS and CBCL-Anxiety were both significantly correlated with higher age, sensory sensitivity, depressive symptoms, somatic complaints, and aggressive behaviors. All three anxiety variables were significantly and positively correlated with total SRS RRB scores. Additionally, the STAIS and STAIT were significantly associated with more severe Compulsion/Adherence behaviors, and the CBCL-Anxiety was also significantly associated with more severe Rule-breaking Behaviors. @*Conclusion@#Self-reported state anxiety showed association patterns similar to those of parent-reported trait anxiety. Future studies investigating the precise operationalization of different anxiety instruments are needed to accurately measure the anxiety of adolescents with ASD.

Validating the Autism Diagnostic Interview-Revised in the Korean Population

Objective@#This study aimed to examine the validity of the Korean version of the Autism Diagnostic Interview-Revised (K-ADI-R) and determine its efficacy in identifying individuals with autism spectrum disorder (ASD). @*Methods@#Data were pooled from several past and ongoing studies as well as clinical records acquired at Seoul National University Bundang Hospital from 2008 to 2017. The K-ADI-R were administered and scored by trained research reliable examiners. Measurements to investigate the validity of the K-ADI-R was through sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), and Cohen’s kappa. @*Results@#A total of 1,271 (age 88.9±62.42 months, male=927) participants were included. The K-ADI-R yielded strong psychometric properties with high sensitivity (86.06–99.27%), specificity (84.75–99.55%), PPV (92.33–99.72%), and NPV (79.43–98.64%). There were significant differences in item scores across the K-ADI-R diagnostic algorithm regardless of age and sex (p<0.001). Agreement between the K-ADI-R and other ASD related measurements ranged between levels of good to excellent. @*Conclusion@#Despite language or cultural boundaries, the K-ADI-R demonstrated high levels of sensitivity, specificity, PPV, and NPV within a wide range of participants; hence, suggesting promising usage as a valuable diagnostic instrument for individuals with ASD.

Prevention of medical malpractice and disputes through analysis of lawsuits related to coronary angiography and intervention

Background/Aims@#Possible fatal complications arising from coronary angiography (CAG), percutaneous coronary intervention (PCI), and coronary artery disease itself, are likely to cause medical disputes. Presenting the current status and reasons for judgments given in lawsuits related to CAG/PCI, this study aimed to identify ways to prevent unnecessary disputes and medical malpractice suits related to CAG/PCI through lawsuit analysis. @*Methods@#A total of 13 cases (20 judgments) found in the Supreme Court of Korea’s Written Judgment Management System from 1998 to 2017 were analyzed. @*Results@#Coronary artery injury was the most common causative complication that led to lawsuits (n = 6, 46%). Six cases (46%) were ruled in favor of the plaintiff for violation of duty of care (n = 4) and duty of explanation (n = 2), respectively. Cases that violated duty of care included two errors in intra-procedure device manipulation, one in pre-procedure diagnosis, and one in management of post-procedure complication. Lack of explanation regarding the risk of complications was pointed out in both cases that violated duty of explanation. The average awarded amount for the damages was 114,436,064 Korean won. @*Conclusions@#Physicians need not fear unfair judgments so long as they follow standard of care because the Court consistently looked at the probability, the foreseeability, and the evidence. Therefore, maintaining standard of care is important. Besides, specific, detailed, and comprehensible explanations, including the risk of complications in addition to the necessity of procedures, are important to ensure the patient clearly understands the possible risk of adverse outcomes.

How Do Children with Autism Spectrum Disorder Encode and Reproduce Visuospatial Stimuli?: Investigation into Visuospatial Processing Abilities and Styles

Objective@#The purpose of this study was to examine the visuospatial processing abilities of children with autism spectrum disorder (ASD) using the Rey Osterrieth Complex Figure (ROCF). @*Methods@#One-hundred thirty-four children with ASD [mean age (MA)=113.56 months], 150 siblings of children with ASD (MA= 111.67 months), and 55 typically developing (TD) children (MA=109.02 months) were included in this study. During their one-time visit, participants completed the ROCF, various autism diagnostic assessments, and the Korean-Leiter International Performance ScaleRevised. Repeated-measures Analysis of Covariance (ANCOVA) and post-hoc Tukey-Kramer comparisons were computed to compare the ROCF scores. Partial correlations and multiple regressions were computed to examine the association between ROCF scores and the severity of autistic symptoms, as measured by the Autism Diagnostic Interview-Revised (ADI-R) among children with ASD. @*Results@#There were significant main effects of the analysis group in Structural and Incidental Accuracy, Error, and Style. More siblings than TD children drew in a part-oriented way, but the performance of the sibling group was comparable or superior to that of the TD group in all parameters. Social Interaction scores of children with ASD were significantly associated with Organization scores in Copy condition. Whether or not a child drew in the Part-Oriented style significantly predicted his/her repetitive and restricted behavior scores. @*Conclusion@#The findings add to the evidence for altered visuospatial processing patterns of ASD as a potential inherent and genetic trait and suggest that this particular cognitive style should not be considered as a deficit. Educational and theoretical implications are discussed.

Current Practices and Future Directions in Patient Safety Education and Curriculum in Medical Schools / 의학교육논단

In 2018, The Ministry of Health and Welfare announced its first comprehensive plan for patient safety, which included the imperative to develop a patient safety curriculum for students studying to become health professionals. The aim of this study is to assess current patient safety education and points of consideration for introducing new curriculum. An online survey was used to understand the status of patient safety education in medical schools, and key informant interviews and focus group interviews were used to collect qualitative data on the experience of patient safety education. The results of the online survey from 16 out of 40 medical schools (40% response rate) and the qualitative data analysis were integrated and analyzed. Twelve schools (75%) had established courses related to patient safety. The qualitative responses suggest that patient safety education is appropriate both before and after clinical training through a variety of educational methods, and that the topics should be linked with clinical training. The challenge of securing lecture time to address patient safety was mentioned as a realistic obstacle. When patient safety education is integrated in future curriculum, it is necessary to consider it as a priority. Moreover, in the early stages of introducing patient safety education, a step-by-step, policy-based approach is required for seamless adoption and settlement.

The Effects of a Support Program for Family Caregivers of Elderly with Dementia on Empowerment and Attitudes toward Dementia / 한국간호교육학회지

PURPOSE: This research was conducted to identify the effects of providing support programs to families of elderly with dementia on family empowerment and attitudes toward dementia. METHODS: A nonequivalent control group pre- and post-test design was used. Participants were 49 family caregivers, experimental (24) and control (25), recruited from families through a dementia support center in Y district. This program implemented Haearim, a support program for family caregivers of demented elders developed by the National Institute of Dementia in 2016. Outcome measures were empowerment and attitudes toward to dementia. Data were analyzed with a χ2-test, independent t-test, Fisher's exact probability test, paired t-test, and repeated measures ANOVA with SPSS/PC version 20.0. RESULTS: Family empowerment (F=6.84, p=.002) and family caregivers' attitudes (F=16.48, p < .001) toward dementia in the experimental group improved significantly more than that of the control group after intervention. CONCLUSION: Results indicate that support programs for families of elderly with dementia are effective in positively changing empowerment and attitudes toward dementia among family caregivers.

The Use of Artificial Intelligence in Screening and Diagnosis of Autism Spectrum Disorder: A Literature Review

OBJECTIVES: The detection of autism spectrum disorder (ASD) is based on behavioral observations. To build a more objective data-driven method for screening and diagnosing ASD, many studies have attempted to incorporate artificial intelligence (AI) technologies. Therefore, the purpose of this literature review is to summarize the studies that used AI in the assessment process and examine whether other behavioral data could potentially be used to distinguish ASD characteristics. METHODS: Based on our search and exclusion criteria, we reviewed 13 studies. RESULTS: To improve the accuracy of outcomes, AI algorithms have been used to identify items in assessment instruments that are most predictive of ASD. Creating a smaller subset and therefore reducing the lengthy evaluation process, studies have tested the efficiency of identifying individuals with ASD from those without. Other studies have examined the feasibility of using other behavioral observational features as potential supportive data. CONCLUSION: While previous studies have shown high accuracy, sensitivity, and specificity in classifying ASD and non-ASD individuals, there remain many challenges regarding feasibility in the real-world that need to be resolved before AI methods can be fully integrated into the healthcare system as clinical decision support systems.

Analysis of lawsuit cases in the Department of Surgery in Korea

PURPOSE: The aim of this study is to prepare medical staff in order to prevent medical malpractice litigation through analysis of litigation cases related to the department of surgery in Korea. METHODS: A total of 94 litigation cases related to the department of surgery, where a certain amount of payment was ordered to the defendant between 2005 through 2010, were analyzed. We examined time of occurrence, amount claimed and awarded in damages, plaintiff claims, and court opinion. RESULTS: An average of 3.2 years was spent from the date of the incident occurring to the end of the litigation procedures. The average amount awarded in judgments for damages was 59,708,983 ± 67,307,264 (range, 1,700,000–365,201,482) Korean won. Cases were found involving the following opinion of the court: violation of duty of care (49 cases), violation of informed consent (7 cases), violation of duty of care and informed consent (5 cases), and settlement, reconciliation, and others (32 cases). By analyzing defendants' negligence in court opinions, diagnosis (30.8%) was the most common, followed by post-operation management (27.7%). CONCLUSION: Physicians have to conduct treatment and surgery based on exact diagnosis and be careful to observe patients' conditions and symptoms after surgery. It is essential to identify the current status and characteristics of medical litigation for reducing further litigation and improving patient safety. In order to create a safe medical environment, national efforts should be made not only by individuals but also at the national level.

Challenges and Strategies for Unified Health System of South and North Korea / 보건행정학회지

This paper aims to make a step-by-step strategy to formulate an unified health system by clarifying and overcoming challenges facing South and North Korea and to estimate costs needed for South Korea to assist North Korea to recover to normal health delivery system. We explored implications through literature review and estimated costs under the assumption that supportive activities be provided for 5 years in three ways: support for the development of health and medical care manpower; support for health and medical facilities; and support for the provision of both preventive and primary health care. Step-by-step strategy is formulated for a unified health system with the cost estimation resulting as follows: in case of basic scenario, a total of 3 trillion and 341 billion won (at present value of the year 2017) is in need for the 5-year period at the initial ‘recovery support stage’ with 135.9 billion won for the development of health and medical care manpower, approximately 2 trillion won for health and medical facilities, and 1.2 trillion won for the provision of both preventive and primary health care. Step-by-step approach is more realistic and applicable in formulating unified health system. Suggested stages are ‘recovery support stage,’ ‘system homogenization stage,’ and ‘unified system stage.’ Strategies at ‘recovery support stage’ suggested in this paper need to be pursued and followed by those at ‘system homogenization stage’ and ‘unified system stage.’

The Legal Doctrine on the Liability of Physicians in Medical Malpractice Lawsuits Involving Complex Regional Pain Syndrome

BACKGROUND: Complex regional pain syndrome (CRPS) involves severe pain and it is difficult to identify the exact cause or pathogenesis. Therefore, there are controversies regarding legal issues related to the establishment of damage in medical malpractice lawsuits involving CRPS. This study aimed to analyze malpractice lawsuits involving CRPS, which occurred after the disputed medical treatment, to provide information on the courts' opinion and characteristics of the cases. METHODS: This study analyzed 23 lawsuit judgments involving CRPS that were sentenced from 2005 to 2015. RESULTS: A total of 12 of the 23 cases were partially ruled in favor of the plaintiff. The average amount (KRW) claimed was 470,638,385 ± 860,634,092 (21,000,000 to 4,020,000,000), and that awarded was 72,906,843 ± 53,389,367 (15,000,000 to 181,080,803). Sixteen of the 23 cases had CRPS type I. In 11 of 23 cases, the site of the pain was located in the lower limb and in 14 cases there was no presence of trauma or event prior to medical treatment. CONCLUSION: Nerve injury was the most frequent reason for taking responsibility in compensating damage in malpractice cases involving CRPS. Physicians should consider various possibilities of such complications in medical practices. It is important to identify and improve areas which need to be improved for patient safety through analyzing the lawsuit judgment cases.

A Study on the Current Status of Medical Lawsuits in Orthopedics in Korea / 대한정형외과학회잡지

PURPOSE: Through the analysis of orthopedics lawsuit rulings, the purpose of this study is to understand the current trends of medical lawsuits in orthopedics in Korea. MATERIALS AND METHODS: An analysis of medical lawsuits in orthopedics was conducted. As the study method, a quantitative analysis was performed on 341 cases. RESULTS: The average period of lawsuits, from the occurrence of the medical accident to end of the ruling, took an average of 4.22 years. The most frequent procedure that was the main cause of the medical accidents was surgery, at 46.3%. When surgery is the main procedure that caused the medical accidents, the result of examining the types of surgeries showed that spine surgery had the highest percentage. For the outcome of the accident, the highest number of cases resulted in disability and for the final court outcome, 40.5% ruled partially in favor of the plaintiff (the patient) with acknowledgement of only the damage incurred due to medical error of the total sum claimed, and dismissal of the claim made by the plaintiff (patient) accounted for 34.3%; 26.1% of cases develop infection. For the amount of claim for damage, the average amount of claim was 181,998,036 won; in the judgement amount, the average amount of judgement was 58,897,161 won. CONCLUSION: The most frequent procedure in orthopedics was surgery and spine surgery comprised a large proportion of these surgeries. Future studies to determine root causes of medical accidents should be conducted to reduce medical lawsuits and to plan against the repeating of medical accidents.

Medical Litigation and the Care of Newborns

PURPOSE: Recently, legal disputes resulting from medical accidents have been increasing annually. The purpose of this study is to determine the causes and characteristics of medical disputes brought as a result of neonatal accidents and to suggest measures to reduce the number of medical malpractice suits. METHODS: Twenty-eight medical malpractice lawsuits brought as a result of neonatal accidents between 2005 and 2009 were analyzed. RESULTS: The average time taken to resolve these lawsuits was approximately 4.4 years. The average gestational age and birth weight of the newborns in these cases were 35.3+/-4.2 weeks and 2,668+/-931 g, respectively. Twelve cases (42.9%) were concluded partially in favor of the plaintiffs, while in 10 (35.7%) cases the plaintiffs lost. In 11 of the 12 cases that were concluded partially in favor of the plaintiffs, the defendants were found guilty of violating their duty of care. Medical accidents resulted in death in 10 cases and physical disability in 18 cases, and cerebral palsy and blindness were the most common physical disabilities. The average compensation amount ordered as damages was KRW 161,389,291+/-12,636,454. CONCLUSION: In medical litigation, the standard of judgment is whether appropriate medical practices were performed based on the patient's symptoms. Thus, to comply with the medical treatment rules is paramount in securing patients' safety and protecting doctors themselves. Individual effort is necessary, but not sufficient to prevent medical accidents; multilateral, systemic reform is also required if the number of neonatal medical accidents is to be reduced.

Prevalence of Anemia and Calcium-Phosphorus Abnormalities in Hemodialysis Patients in Southwestern Seoul / 대한내과학회지

BACKGROUND/AIMS: The number of hemodialysis patients and dialysis centers is increasing each year, but there are no quality standards for facilities. Thus, the Korean Society of Nephrology carried out a pilot project regarding a hemodialysis center accreditation system. This study was aimed at surveying the prevalence of anemia and abnormalities of calcium or phosphorus metabolism in hemodialysis patients in southwestern Seoul. METHODS: We investigated anemia, serum calcium, and phosphorus levels in 1,524 patients in 25 hemodialysis units. The rate of iron injections in patients with iron deficiency was also evaluated. Each item was compared between accredited (n = 12) and non-accredited centers (n = 13). RESULTS: The mean hemoglobin in subjects was 10.5 +/- 1.5 g/dL. The prevalences of anemia and iron deficiency were 27.4% and 25.2%, respectively. The rate of iron injection in patients with iron deficiency was 48.1%. The mean phosphorus level was 5.1 +/- 1.9 mg/dL and the proportion of patients with Ca x P < 55 mg2/dL2 was 70.7%. The prevalence of anemia, iron deficiency, and Ca x P were similar between accredited and non-accredited centers. The rate of iron injection in iron deficiency was higher in accredited (65.6%) than non-accredited centers (30.9%). CONCLUSIONS: Management of anemia and levels of calcium or phosphorus were acceptable in hemodialysis patients in southwestern Seoul, although some facilities should make more efforts to improve iron deficiency. The availability of data from a hemodialysis center accreditation system allowed us a unique opportunity to further explore the relationships between anemia, abnormalities of mineral metabolism, and outcomes.

Overview of healthcare system in North Korea

In this study, we analyzed the healthcare system of North Korea using Kleczkowski's model which categorizes national healthcare infrastructure into five components: health resources, organization, healthcare delivery system, economic support, and management. It was found that the healthcare system in North Korea, which provides clinical medicine, Koryo medicine and preventive medicine, is constituted of a physician system of independent geographic sectors and centralized delivery system while maintaining free universal health coverage. These systems are all managed by the government and the People's Committee Party. However, North Korea has been confronted with severe economic difficulties since the 1990s, such that we question whether the healthcare system has been able to function properly despite of the lack of resources in general throughout the country.

Muscle Weakening and Change of Tension According to Degree of Superior Rectus Z-Myotomy in Rabbits

PURPOSE: To identify the muscle weakening effect and the change of muscle tension according to degree of superior rectus Z-myotomy in rabbits. METHODS: After dissection of superior rectus in 15 rabbits (30 eyes), marking was done on 10 mm apart from muscle insertion. Then, Z-myotomy was done on 2 mm and 8 mm apart from muscle insertion which are two different positions on apposite sides. 25%, 50% and 75% Z-myotomy were defined as group 1 (10 eyes), group 2 (10 eyes) and group 3 (10 eyes). After Z-myotomy, the change of muscle lengthening between muscle insertion and marking, and muscle tension were measured. At 4 weeks after Z-myotomy, all parameters were re-measured. RESULTS: After Z-myotomy all markings moved posteriorly, and showed result as 10.83 +/- 0.13 mm in group 1, 11.02 +/- 0.17 mm in group 2 and 12.01 +/- 0.23 mm in group 3 respectively. Muscle tension result showed as 3.98 +/- 0.22 mm in group 1, 3.54 +/- 0.18 mm in group 2 and 2.87 +/- 0.25 mm in group 3. In comparison of three groups, group 2 and group 3 showed the significant results (p < 0.05). At 4 weeks after Z-myotomy the markings showed result as 10.55 +/- 0.14 mm, 10.85 +/- 0.20 mm, 11.91 +/- 0.14 mm respectively, and in group 2 and group 3 the significant changes were seen (p < 0.05). Muscle tensions were 4.01 +/- 0.31 mm, 3.88 +/- 0.53 mm, 3.12 +/- 0.42 mm respectively. There were significant results in group 2 and group 3 (p < 0.05). CONCLUSIONS: 75% Z-myotomy of superior rectus showed significant results in muscle weakening and decreasing muscle tension.

Discussions and Implications of the Recent Enactment & Revision of the Healthcare Law

Recently, there have been many changes in the area of healthcare. There is no certainty how these changes will affect the healthcare system and public health. However, to at least have these changes positively implemented, it is clear that evaluation through continuous monitoring is necessary. The enforcement of the Medical Institution Accreditation and Medical Dispute Mediation Law as well as legal revisions regarding the public healthcare system are changes to improve the quality of healthcare, while at the same time, provide penalties for infractions of the new law such as medicine/medical device rebates; moreover, legal revisions regarding telemedicine are anticipated to impartially vitalize technical development as well as the pharmaceutical industry. For these changes to have a positive effect on the medical field and people's lives, an accurate comprehension of the system and understanding of the details is necessary to be able to respond sensitively to any changes in the future. Therefore, this paper examined the background information on the current discussion on the changes in the healthcare system, examined the detailed content of the system, and reviewed the areas that were in dispute as well as the main issues to contemplate the expected effects of the changes and future tasks that may be generated as a result. These considerations will act as foundation for an in depth understanding of recent trends in the healthcare system.

A Case of Oncocytoma of the Caruncle

PURPOSE: To report a case of oncocytoma of the caruncle. CASE SUMMARY: A 63-year-old woman visited our clinic due to a mass in her left caruncle that developed five months prior to admission. At the time of her visit, her visual acuity was 0.8 in the right eye and 1.0 in the left eye, and there was a small mass in her left eye. She did not have any pain, and no discharge was apparent. All blood sample results were within the normal range. Also, we did not perform any radiologic studies. We administered systemic antibiotics and excised the mass from the caruncle of her left eye. Her biopsy read 'Oval cells with cytoplasm stuffed with eosinophilic granular material'. These findings are compatible with oncocytoma of the caruncle. CONCLUSIONS: The oncocytoma of the caruncle requires regular follow-up, which differs from the treatment plans for hemangioma, nevi, and cysts.
