Background:
Infantile hemangioma (IH) is one of the most common tumors in infants. IH occurs more commonly in premature and low birth weight infants, but only a few studies have analyzed the risk factors for IH in neonatal intensive care units (NICUs) in Korea.
Objective:
We investigated the risk factors for IH in patients admitted to the NICU at a single institution.
Methods:
A single-center retrospective case-control study was conducted in 37 patients with hemangioma and 185 matched-control babies who were admitted to the NICU between 2013 and 2020. Odds ratios (ORs) and multivariate conditional logistic regression models were used to determine the associations between IH and the potential risk factors.
Results:
Of the 1,206 neonates admitted to the NICU, 37 had IH, and the prevalence was 3.1%. IH was most commonly found on the trunk (33.3%), followed by the head and neck (29.4%). After adjustment, the risk factors found to be significantly associated with IH were female sex (OR=3.0, 95% confidence interval [CI]=1.4∼6.8), extreme preterm (OR=6.9, 95% CI=1.3∼38.0), very low birth weight (OR=11.9, 95% CI=2.9∼49.3), low 1-minute Apgar scores of <7 (OR=2.3, 95% CI=1.1∼4.9), and multiple gestation (OR=5.0, 95% CI=1.7∼14.9).
Conclusion
This matched case–control study revealed that risk factors such as female sex, extremely preterm birth, very low birth weight, low 1-minute Apgar score, and multiple gestations may affect the occurrence of IH. Therefore, if these risk factors are present, they need to be actively managed at an early stage through close physical examination to prevent complications.

BACKGROUND: Therapeutic education is important for successful management of atopic dermatitis (AD). OBJECTIVE: To provide effective therapeutic education, clear common misunderstandings, and answer questions regarding AD among patients and caregivers. METHODS: A questionnaire survey was conducted for patients and caregivers who visited the Department of Dermatology at Seoul National University Hospital, Seoul, Korea, regarding the course, etiology, and management of AD. RESULTS: Among the 327 subjects who participated in the study, only 35.2% were aware of the natural course of AD, which usually improves with age. Many subjects (53.2%) misinterpret AD relapse as resistance to topical steroids. We found that 87.8% of subjects were under the impression that improvement in a patient's immunity can improve the symptoms of AD. Dietary restriction was considered an essential management strategy, and 59.0% of subjects agreed to delay the initiation of weaning foods. Most subjects did not have accurate information about cleansing methods, and 30.9% of subjects reported that they used only water without any cleanser. We noted that 47.5% of subjects obtained information regarding AD from medical doctors who they considered the most reliable sources (82.5%). Subjects preferred printed materials (41.3%) over seminars or video-clips to obtain educational information. CONCLUSION: Therapeutic education regarding the course, etiology, and management of AD using printed materials put together by physicians would be a valuable tool for the effective management of AD. Institutional support such as educational programs covered by the National Health Insurance Service is required.

Purpose:
This study aimed to compare the long-term functional and patient-reported outcomes between intra-corporeal delta-shaped gastroduodenostomy and gastrojejunostomy after laparoscopic distal gastrectomy for gastric cancer.
Materials and Methods:
We retrospectively reviewed clinicopathological data from 616 patients who had undergone laparoscopic distal gastrectomy for stage I gastric cancer between January 2015 and September 2020. Among them, 232 patients who had undergone delta-shaped anastomosis and another 232 who had undergone Billroth II anastomosis were matched using propensity scores. Confounding variables included age, sex, body mass index, physical status classification, tumor location, and T classification. Postoperative complications, nutritional outcomes, endoscopic findings, and quality of life (QoL) were compared between the 2 groups.
Results:
No significant differences in postoperative complications or nutritional parameters between the two groups were observed. Annual endoscopic findings revealed more residual food and less bile reflux in the delta group (P<0.001) than in the Billroth II group. Changes of QoL were significantly different regarding emotional function, insomnia, diarrhea, reflux symptoms, and dry mouth (P=0.007, P=0.002, P=0.013, P=0.001, and P=0.03, respectively).Among them, the delta group had worse insomnia, reflux symptoms, and dry mouth within three months postoperatively.
Conclusions
Long-term nutritional outcomes and QoL were comparable between the delta and Billroth II groups. However, more residual food and worse short-term QoL regarding insomnia, reflux symptoms, and dry mouth were observed in the delta group. Longer fasting time before endoscopic evaluation and short-term symptom management would have been helpful for the delta group.

Journal of the Korean Society of Radiology 2024;85(5):926-936
Purpose:
To assess the reliability and accuracy of an automated Cobb angle measurement (ACAM) using a convolutional neural network (CNN) for scoliosis evaluation and to compare measurement times.
Materials and Methods:
ACAM was applied to spine radiographs in 411 patients suspected of scoliosis. Observer 1 (consensus of two musculoskeletal radiologists) and observer 2 (a radiology resident) measured Cobb angle (CA). CA measurements were categorized using observer 1’s measurements as the reference standard. Inter-observer reliability and correlation were assessed using intraclass correlation coefficient (ICC) and Spearman’s rank correlation coefficient, respectively. Accuracy and measurement time of ACAM and observers were evaluated.
Results:
ACAM demonstrated excellent reliability and very high correlation with observer 1 (ICC = 0.976, Spearman’s rank correlation = 0.948), with a mean CA difference of 1.1. Overall accuracy was high (88.2%), particularly in mild (92.2%) and moderate (96%) scoliosis. Accuracy was lower in spinal asymmetry (77.1%) and higher in severe scoliosis (95%), although the CA was lower compared to the observers. ACAM significantly reduced measurement time by nearly half compared to the observers (p < 0.001).
Conclusion
ACAM using CNN enhances CA measurement for assessing mild or moderate scoliosis, despite limitations in spinal asymmetry or severe scoliosis. Nonetheless, it substantially decreases measurement time.
