We have compared the computed tomographic(C. T.) findings with those of conventional roentgenogram(simple AP and lateral radiograms) in 18 cases of osteochondritis dissecans of the capitellum humeri available for review. Among the 18 cases, 2 cases of them had a lesion of osteochondritis dissecans on C. T. which, however, had not been found on conventional rentgenograms. Fro the 5 cases, which had not clearly found on conventional rentgenograms, 2 loose body on conventional view, 3 cases had different numbers and locations of loose body on C. T. films. On the bases of our findings, we recommend that C. T. is necessary in early detection and the determination of anatomical location and status of osteochondritis dissecans of capitellum.

Purpose: This study aimed to develop an untact visit service based on an application that can be utilized in the pediatric intensive care unit (PICU) during COVID-19. Methods: This study adopted the double diamond process of service design comprising the discovery, defining, and development stages. Results: We developed an untact visit service based on an application that considered the child’s status, schedule, photo, and video messages, and so on. Moreover, we derived a service flow regarding the required roles and the type of flow shown between each stakeholder. Conclusion Considering the ongoing pandemic, the untact visit service is designed to increase rapport and participation of parents, share the child’s information in real-time, and provide one-stop service without increasing healthcare providers’ work. It will be a useful visit service that can be applied and evaluated in various hospital settings and the PICU.

BACKGROUND: Parkinson disease (PD) is caused by selective cell death of dopaminergic neurons in the substantia nigra. An early onset form of PD, autosomal recessive juvenile parkinsonism has been associated with a mutation in the parkin gene. The function of parkin is known to remove misfolding proteins and protect cell death. We aimed to investigate the role of parkin against oxidative stress in neuronal cells. METHODS: Parkin knockout embryonic stem cells (PKO ES cells) were differentiated into neurons by adherent monolayer culture method. Oxidative stress was induced by the treatment of 1-methyl-4-phenylpyridinium (MPP+) in neurons derived from wild type and PKO ES cells, and cell viability was examined by MTT assay. After exposure to MPP+, Tuj1-positive cell population was compared between PKO and wild type cells by fluorescence activated cell sorter (FACS) analysis. The activated caspase3 protein level was also measured by Western blot analysis, FACS and immunocytochemistry. RESULTS: There was no difference in the efficiency of neuronal differentiation between wild type and PKO ES cells. After exposure to MPP+, no significant differences were found in cell viability and Tuj1-positive cell population between the two groups determined by MTT assay and FACS analysis, respectively. The activated caspase3 protein levels examined by Western blot analysis, FACS and immunocytochemistry were not changed in PKO cells compared with those of wild type cells after MPP+ treatment. CONCLUSION: These results suggest that PKO neuronal cells including dopaminergic neurons are not sensitive to caspase3-dependent cell death pathway during the response against MPP+-induced oxidative stress.

OBJECTIVE: To examine inter-rater reliability of the Korean version Gross Motor Function Measure (K-GMFM-88) and the Gross Motor Performance Measure (GMPM) based on the video clips. METHOD: We considered a sample of 39 children (28 boys and 11 girls; the mean age=3.50+/-1.23 years) with cerebral palsy (CP). Two pediatric physical therapists assessed the children based on video recordings. RESULTS: For the K-GMFM-88, the intraclass correlation coefficient (ICC3, 1) ranged from .978 to .995, and Spearman's correlation coefficient ranged from .916 to .997. For the GMPM, ICC3, 1 ranged from .863 to .929, and Spearman's correlation coefficient ranged from .812 to .885. With the gross motor function classification system classified according to the functional level (GMFCS I-II vs. III-V), the ICCs were .982 and .994 for the K-GMFM-88 total score and .815 and .913 for the GMPM total score. There were good or high correlations between the subscales of the two measures (r=.762-.884). CONCLUSION: The K-GMFM-88 and GMPM are reliable tools for assessing the motor function of children with CP. These two methods are highly correlated, which adds more reliability on them. Thus, it is advisable to use K-GMFM-88 and GMPM for children with CP to assess gross motor function.

OBJECTIVES: The aims of this study were to investigate the pattern of stress coping strategies and the effects of stress coping strategies on quality of life in patients with schizophrenia. METHODS: Stress coping strategies and quality of life were examined using Ways of Coping Checklist and Schizophrenia Quality of Life Scale for 98 patients with schizophrenia. Stress coping strategies were composed of problem-focused coping, social support seeking, emotion-focused coping, and wishful thinking. Among these, problem-focused coping and social support seeking were active coping strategies while emotion-focused coping and wishful thinking were passive coping strategies. Positive and Negative Syndrome Scale (PANSS) and Beck's Depression Inventory (BDI) were also administered. RESULTS: Active coping scores were higher than passive coping scores in patients with schizophrenia. Quality of life was higher in the active coping group compared to the passive coping group. Active coping usage was a significant predictor of higher quality of life even after controlling for gender, age, PANSS, and BDI scores. CONCLUSION: Patients with schizophrenia used more active coping strategies than passive coping strategies, which showed significant association with higher quality of life. A treatment program to provide education on use of active coping strategies in a proper and flexible way might contribute to enhanced quality of life in patients with schizophrenia.
