Background: Congenital muscular torticollis (CMT) is a common musculoskeletal disorder occurring at birth or in infancy.Purpose: This study aimed to investigate the risk of comorbidities in CMT and explore the differences in neurodevelopmental outcomes between children who received physical therapy and those who did not.Methods: Children with CMT born in 2008 and 2009 in Korea were included. CMT was defined as a primary diagnosis of congenital deformity of sternocleidomastoid muscle according to the International Classification of Diseases 10th revision. Here we investigated the associated neurological/musculoskeletal comorbidities of children with CMT versus those of the general population. We divided those with torticollis into treatment and nontreatment groups and assessed their developmental outcomes within both groups of children using the Korean-Ages and Stages Questionnaire (K-ASQ).Results: Of the 917,707 children, 0.2% (n=1,719) were diagnosed with CMT. In children with torticollis, the prevalence of congenital hip deformities significantly increased to 4.5% (n=78). The prevalence of congenital head/spine deformities and other congenital malformations of the skull and facial bones increased to 2.6% (n=44), while the prevalence of congenital foot deformities was 2.4% (n=42). The risk ratio (RR) for delayed development based on the K-ASQ was higher for the total assessment (adjusted RR=0.97; 95% confidence interval, 0.93–0.99) in the CMT patients without physical therapy than in those with therapy. There was no significant intergroup difference in the assessment of each developmental area.Conclusion: The prevalence of comorbid musculoskeletal deformities was higher in children with CMT than in the control group. The risk of developmental delay was higher in children who did not receive physical therapy than in those who did.

Background: Limited data are available on hepatitis C virus (HCV) infection in persons who inject drugs (PWID) in South Korea. The present study aimed to investigate the seroprevalence of HCV antibodies, risk factors for HCV seropositivity, and HCV treatment status in PWID between January 2012 and May 2022. Methods: We retrospectively reviewed the medical records of 418 drug users who underwent HCV antibody testing in three hospitals caring for 90% of known PWID in South Korea, of whom 373 were PWID. Results: The HCV seroprevalence was 39.7% (148/373) in PWID vs. 6.7% (3/45) in noninjection drug users (P < 0.001). Age ≥ 40 years, hospital type (58.2% in the prison hospital vs. 34.0% in the private hospital), and enrollment year (68.2% in 2012–2014 vs. 30.0% in 2021–2022) were independently associated with HCV seropositivity. Among the HCVseropositive PWID, 90.5% (134/148) were diagnosed with HCV infection; however, only 6.8% (10/148) received HCV treatment. The hepatitis B virus surface antigen and human immunodeficiency virus antibody positivity were 4.0% (14/352) and 1.9% (6/317) in tested PWID, respectively. Conclusion: The HCV seroprevalence in PWID was 39.7% with a very low treatment rate, which prompts active measures to test and treat PWID for HCV infection in South Korea.

전기철도시스템에서 전기설비는 가공전차선로, 전기차량 및 레일로 구성되는 고압 전력급전계통과 신호궤도회로, 본드 및 전철기, 각종 통신·제어설비, 열차통신을 위한 각종 무선설비, 기타 전원으로 사용되는 저압의 여러 가지 전기설비로 구성되어 있으며, 이러한 설비들은 모두 매설지선 접지전극에 공통으로 연결되어 있다. 공통(공용) 방식의 접지시스템에서 지락고장이 발생하면 고장전류가 대지로 흘러가므로 대지전위 분포가 나타나게 되어 전기설비의 내부 및 주변에 전위차가 발생하여 인체의 안전이나 설비의 절연에 위험을 초래하게 된다. 본 연구에서는 고통접지 방식의 철도시스템에서 인공으로 지락고장을 발생시켜서 고장전류의 분류 및 전위 분포 특성에 대하여 측정하고 분석하였다. Power supply system of electric railway is compose with distribution line, electric rolling stock, rail, track circuit of signal and communication, protection facilities and so on. All device of electric railway system is connected by buried earth wire. Power supply distribution systems are consisted of catenary condutcor, an overhead protective wire and a buried earth wire. Phase to ground faults are possible one of the maximum number of faults in the power distribution system of the electric railway. During a ground fault the maximum fault current and neutral to ground voltage will appear at the rail nearest to the fault. point. In this paper phase to ground faults were staged at the specified steel pole along the rail and measured the ground fault current distribution in the ground fault current, and measured potential nearest to the fault point.

Purpose: We aimed to analyze the correlations between the Bayley Scales of Infant Development (BSID)-III and Korean Developmental Screening Test (K-DST) in very-low-birth-weight (VLBW; birth weight <1,500 g) preterm infants. Methods: We enrolled 53 VLBW infants (mean gestational age, 28.9±2.11 weeks; mean birth weight, 1,158.5±241.1 g) and assessed them using the BSID-III and K-DST at a corrected age of 18 to 24 months. We analyzed the correlations between the BSID-III and K-DST subdomains and evaluated whether the estimated developmental levels were consistent with the corrected ages. Results: In the BSID-III, the composite scores for cognition, motor, and language were 105.9±13.1 (median, 105; 66th percentile; 95% confidence interval [CI], 98 to 113), 100.9±12.4 (100; 50th percentile; 95% CI, 92 to 108), and 94.9±16.8 (97.5; 34th percentile; 95% CI, 87 to 102), respectively. The scaled scores for receptive/expressive language and gross/fine motor were 9.9±2.9 (10.5)/8.2±2.7 (8) and 9.6±2.4 (9)/10.6 ±2.3 (10), respectively. In the K-DST, the mean scores of cognition (17.8±4.7 [18.5]), language (16.6±7.2 [20]), fine motor (19.4±3.4 [20]), gross motor (19.9±3.8 [21]), sociality (18.6±4.7 [20]), and self-control (17.3±5.1 [18]) were within the range of normal developmental status. Among the overlapping subdomains, cognition (r=0.58, P= 0.003) and language (r=0.86, P<0.001), but not fine and gross motor status (r=0.05, P= 0.79; r=0.16, P=0.44, respectively), showed significant correlation between the BSID-III and K-DST. Conclusion: The language and cognition domains of the K-DST were significantly correlated with the BSID-III in preterm VLBW infants. Clinicians should consider these discrepancies and correlations when evaluating the developmental status of preterm VLBW infants.

Objective: In vitro fertilization (IVF) pregnancy is increasing. The recent reviews have reported the perinatal outcomes of IVF were preterm birth, low birth weight, small for gestational age, congenital malformations, neurologic disorders and epigenetic defects. We aimed to analyze the perinatal outcomes of IVF compared with natural pregnancy on very low birth weight infants. Methods: Our study population was derived from Neonatal Intensive Care Unit of the Gangnam CHA Medical Center from 2010 to 2014, consisting of singleton live births in very low birth weight infants. We grouped IVF group (n=24) and control group (natural pregnancy, n=112). We analyzed two groups about maternal characteristics, neonatal characteristics, and outcomes (retinopathy of prematurity [ROP], bronchopulmonary dysplasia [BPD], periventricular leukomalacia [PVL], necrotizing enterocolitis [NEC], death). Results: Maternal age was significantly older in IVF group (34.9±0.9 vs. 33.0±0.4, P=0.03). The Apgar score 1 minute of the IVF group was significantly lower than control group (4.0±0.3 vs. 4.8±0.2, P=0.03). But there were no other significant differences of neonatal morbidities. In univariate logistic regression analysis with IVF, the odds ratio of maternal age was 1.13 (95% confidence interval: 1.01-1.27, P=0.04). The relative risk of RDS, BPD, PVL, and ROP was increased, but it was not significant in univariate and multivariate logistic regression. Conclusion: As the maternal age increased, IVF pregnancy was significantly higher. The relative risk of RDS, BPD, PVL, and ROP was high in IVF group, but it was not significant in univariate and multivariate logistic regression.
