ABSTRACT
Objective@#To investigate the association between vitamin E and handgrip strength (HGS) with multiple factors. @*Methods@#A total of 1,814 participants were included (822 men and 981 women) from the Korean subjects of the 7th Korea National Health and Nutrition Examination Survey in 2018. Data were analyzed using multiple logistic regression to determine the correlation between vitamin E and HGS with potential confounding factors. @*Results@#In the multiple logistic regression model, only the young age group (19–40 years) of men showed a positive relationship between vitamin E and HGS. However, in older age groups (41–80 years) of men and all age groups of women, there was no statistically significant result. After adjusting for confounding factors, young men showed higher vitamin E levels and higher HGS. Conversely, women and older age groups did not show significant results after adjusting for confounding factors. @*Conclusion@#In this study, the serum vitamin E level had a positive effect on HGS in young men (<40 years). Further research is needed on this topic regarding vitamin E intake and other objective measures.

ABSTRACT
Congenital muscular torticollis is a common musculoskeletal disorder characterized by the shortening of the sternocleidomastoid muscle, thus leading to an ipsilateral tilt of the head and contralateral rotation of the face. Most of the congenital muscular torticollis is ipsilateral. Bilateral congenital muscular torticollis is extremely rare. Congenital muscular torticollis is known to be associated with several musculoskeletal and neurologic disorders including brachial plexus injury. Therefore, early diagnosis and intervention are crucial for the treatment and prevention of associated complications. Here, we report a case of a 1-month-old infant with bilateral congenital muscular torticollis suspicious of Erb-Duchenne palsy.
ABSTRACT
Objective@#To compare the relationship of the Bayley Scales of Infant and Toddler Development 3rd Edition (K-BSID-III) language score and the Sequenced Language Scale for Infant (SELSI) score and evaluate the sensitivity and specificity of K-BSID-III language score and optimal cutoff value with receiver operator characteristic (ROC) curve analysis in infants and toddlers with delayed language development. @*Methods@#A total of 104 children with suspected language developmental delay were included in this retrospective study. Subjects were tested using the K-BSID-III and SELSI and subdivided into several groups according to the severity of language scores. ROC curve analysis was performed to assess K-BSID-III for delayed language development. @*Results@#Receptive and expressive language subscales of the K-BSID-III showed markedly significant correlation with the SELSI scores (p<0.001). ROC analysis showed an area under the curve of 0.877 (p<0.001) in SELSI receptive score and 0.935 (p<0.001) in SELSI expressive score. The optimal cutoff value where sensitivity of 85% and specificity of 81% were achieved with the K-BSID-III receptive score was 1.50 (between average and low average) in the SELSI receptive score. The optimal cutoff value where sensitivity of 96% and specificity of 82% were achieved with the K-BSID-III expressive score was also 1.50 in the SELSI expressive score. @*Conclusion@#In this study, the correlations between K-BSID-III and SELSI language scores were statistically significant. However, the interpretation should be considered carefully in low average group due to tendency of underestimation of delayed language development.
