BACKGROUND/OBJECTIVES: The illustrated Healthy Eating Practice Questionnaire (HEPQ) was previously developed to assess food preferences, eating behaviors, hand/oral hygiene practices, and nutrition knowledge among Korean preschool children. Nevertheless, the lack of an integrated scoring system has limited its interpretability. This study developed a scoring system and a web-based platform with tailored feedback using a child-parent dyad approach. SUBJECTS/METHODS: The development process consisted of 5 phases: 1) questionnaire preparation for online use, 2) formulation of the scoring system, 3) determination of the cut-off values for three levels of healthy eating practices based on a child-parent survey, 4) technical development of the online platform, and 5) usability evaluation. A scoring system was established by standardizing the domain scores to a 100-point scale. One hundred child– parent pairs participated in the survey to calculate the Healthy Eating Practice Score (HEPS) and determine cut-off values for the HEPS levels. The validity of the cut-off values was examined by a comparison with the Nutrition Quotient for Preschoolers (NQ-P). A web-based platform was developed, and 47 child–parent pairs were used to assess its usability. RESULTS: Significant positive correlations were observed between child and parent HEPS across all domains. The HEPS-based classification showed good discriminative ability because higher HEPS levels were consistently associated with higher NQ-P scores in children and parents. The web-based HEPQ was easy to use and understand, and almost all participants (97.9% of children and 93.6% of parents) reported no difficulties using the platform. CONCLUSION The web-based HEPQ platform with an integrated scoring system provides a valid, user-friendly tool for assessing and interpreting healthy eating practices in preschool children. This platform supports parental engagement in children’s healthy eating practices and provides a practical tool for evaluating the effectiveness of nutrition education in early childcare settings.

Lipogranuloma is a chronic inflammatory response to lipid material within tissues and may develop secondary to fat necrosis, trauma, or exogenous lipid exposure. We report a case of postoperative mid-sternal lipogranuloma with milky discharge in a 35-year-old man that occurred 6 months after surgery for gynecomastia performed through a periareolar incision with adjunctive liposuction. The patient presented with two firm, non-tender nodules at the sternal midline, distant from the operative site, and laboratory findings were unremarkable. Surgical exploration revealed milky white discharge, and histopathologic examination demonstrated lipid-laden macrophages, multinucleated giant cells, and fibrosis, consistent with lipogranulomatous inflammation. No evidence of malignancy or infection was identified, and no recurrence was observed during 2 years of follow-up. The proposed mechanisms include displacement of residual ductal epithelium or lipid material during surgical manipulation, as well as postoperative fat necrosis leading to secondary lipogranulomatous inflammation. This case highlights that postoperative lipogranulomatous inflammation may present at sites distant from the primary operative field. Recognition of this entity is important in the evaluation of postoperative chest wall masses to avoid misdiagnosis and unnecessary intervention.

Full-thickness skin grafting (FTSG) is frequently used to reconstruct facial soft tissue defects because it provides favorable color and texture matching. Secondary cystic lesions, including milia or epidermal cysts, that develop after FTSG are rare. A 29-year-old woman sustained a dog-bite injury resulting in a 4.5× 2.5 cm defect involving the philtrum and upper lip. The philtrum was reconstructed using a full-thickness skin graft harvested from the retroauricular area, while the upper lip was repaired using a mucosal V-Y advancement flap. Ten months later, hypertrophic scarring developed, and a second FTSG was performed using contralateral retroauricular skin. Despite repeated intralesional triamcinolone injections, the grafted area became tender and pruritic, with the appearance of multiple milia-like lesions. Over the subsequent 9 months, three recurrent cystic nodules developed within the scar tissue and were serially excised. Histopathological examination confirmed the diagnosis of secondary milia. After complete excision, no recurrence was observed for over 3 years. We discuss possible contributing mechanisms, including adnexal survival within grafts and the role of remnant epidermis or ductal obstruction. Awareness of this complication may help guide donor-site selection and wound-bed preparation in perioral reconstruction.

Epidermoid and dermoid cysts are common congenital lesions of the pediatric periorbital region arising from ectodermal inclusion during embryologic development. Although these lesions originate in the soft tissue, chronic pressure from long-standing masses may induce cortical depression or remodeling of adjacent craniofacial bones, particularly in young children with malleable skeletal structures. We report a case of a 26-month-old girl presenting with a small periorbital epidermoid cyst associated with pressure-induced depression of the zygomatic surface. Radiologic evaluation revealed a well-circumscribed cystic lesion abutting the frontal process of the zygoma with smooth cortical indentation and no features suggestive of aggressive osseous pathology. Complete excision was performed through a lateral brow approach with preservation of the periosteum. Histopathologic examination confirmed an epidermoid cyst. Postoperative follow-up demonstrated progressive spontaneous restoration of the zygomatic contour without the need for bone grafting or alloplastic materials, reflecting the osteogenic potential of the pediatric periosteum. This case emphasizes the importance of distinguishing secondary pressure-related bone remodeling from true intraosseous lesions in the pediatric craniofacial region and highlights the capacity for natural osseous recovery following removal of the compressive source. A brief review of relevant embryologic and radiologic considerations is also provided.

Background: The conventional magnetic resonance imaging (MRI) grading system for foraminal stenosis (FS), known as the Lee classification, was introduced in 2010 and is widely utilized in clinical practice. Previous studies have reported that the conventional grading system for FS lacks prediction ability for surgical treatment. The purpose of this study was to develop a novel MRI grading system for lumbar FS with improved prediction ability for surgical treatment by incorporating facet effusion to indicate segmental instability. Methods: We retrospectively reviewed patients diagnosed with lumbar FS between 2011 and 2017 who had a follow-up period of at least 5 years. The FS severity was assessed using a conventional MRI grading system developed by Lee et al. We recorded whether the patient underwent surgical treatment for FS during the follow-up period and the time from the initial diagnosis to surgery. Survival analysis using a Kaplan-Meier curve and log-rank test was performed to verify the impact of FS severity on the surgical treatment. We performed additional survival analysis after modifying the grading system by incorporating the presence of excessive facet joint effusion assessed using axial MRI. We also compared the discrimination ability of the modified and conventional grading systems using Uno’s concordance index (C-index). Results: In total, 235 patients with a mean age of 63.7 years were included in this study. During the mean follow-up period of 8.1 years, 63 patients underwent surgical treatment for FS. The conventional grading system revealed no significant difference in survival between the grade 2 and 3 groups (p = 0.104). Conversely, the modified grading system revealed a significant difference in survival between the new grade 2 and 3 groups (p < 0.001). After modification, the discrimination ability, assessed using Uno’s Cindex, significantly improved from 0.69 to 0.73. Conclusions The Facet Effusion-Incorporating Grading System, which adds excessive facet joint effusion to the conventional MRI grading framework, demonstrated improved predictive value for surgical treatment and better discriminatory ability compared with the original system.

Background: Research on the relationship between the progression of interstitial lung abnormalities (ILA) and serum biomarkers, including white blood cell differential counts and Krebs von den Lungen-6 (KL-6), is limited. This study aimed to examine the clinical characteristics of patients with ILA and evaluate the association between disease progression and serum biomarkers. Methods: This retrospective cohort study analyzed data from 159 patients (63 with ILA and 74 with interstitial lung diseases) between October 2021 and September 2022. Data collected included clinical characteristics, pulmonary function tests, chest computed tomography (CT), complete blood cell counts, and KL-6 levels. In 52 of these patients who had previously undergone chest CT, the utility of serum biomarkers in reflecting radiologic progression was assessed using receiver operating characteristic curve analysis. Results: Patients with ILA exhibited clinical characteristics similar to those with idiopathic pulmonary fibrosis. Serum KL-6 levels did not correlate with forced vital capacity or diffusing capacity of the lung for carbon monoxide in patients with ILA. Among the 52 patients with ILA, 13 demonstrated radiologic progression. Serum KL-6 displayed moderate predictive performance, with area under the curves ranging from 0.57 to 0.89 (p=0.014) for radiologic progression. Levels of KL-6 greater than 400 U/mL were more frequently observed in patients with radiologic progression (61.5% vs. 20.5%, p=0.006). In multivariate analysis, age and KL-6 were independently associated with radiologic progression in patients with ILA. Conclusion Serum KL-6 levels may serve as a potential indicator of ILA progression in asymptomatic patients. Those with KL-6 levels exceeding 400 U/mL should be closely monitored for radiologic progression.

It is difficult to determine a cause of bile duct stricture and dilatation. Eosinophilic cholangitis, a rare benign condition, may be one cause of bile duct stricture and dilatation. It can be evaluated using various methods of histopathology, radiographs, endoscopy, and hematologic findings. Treatment generally involves steroid therapy which can lead to improvement. This case report will discuss eosinophilic cholangitis, emphasizing that while it can easily be overlooked but should be considered in differential diagnoses.

Purpose: The purpose of this study is to compare scapular alignment, muscle strength around the scapula and neck according to the classification of forward head posture (FHP), round shoulder posture (RSP) and forward head with round shoulder posture (FHRSP). Methods: Scapular alignment, muscle strength around the scapula, and neck strength were measured according to the FHP and RSP alignment classification for male college students. Scapular alignment was confirmed by measuring acromial depression, scapular lateral displacement, and scapular acromion distance. Muscle strength was measured during isometric contraction of upper trapezius (UT), middle trapezius (MT), lower trapezius (LT), and neck muscles. Results: Acromial depression was significantly greater in the FHP (7.20±1.02 cm) than in the RSP group (5.60±1.26 cm) and FHRSP (5.26±1.75 cm) (p＜0.05). The strength of the UT was significantly greater in the FHRSP (1.12±0.12 N/BW) than in the FHP (0.87±0.19 N/BW), and the strength of the LT was significantly greater in the control group (0.20±0.04 N/BW) than in the FHP (0.15±0.03 N/BW) and RSP (0.15±0.04 N/BW) (p＜0.05). The LT:UT ratio was significantly greater in the control group (0.20±0.05) than in the FHRSP (0.15±0.02) (p＜0.05). Conclusion UT strength was higher in RSP subjects with scapular elevation accompanied by FHP than in those with FHP alone. And LT strength and the LT:UT ratio were higher in subjects withno abnormalities in postural alignment. We suggest that these results can serve as a reference for evaluation and intervention according to postural alignment in clinical practice.

Irritable bowel syndrome (IBS) is a chronic, disabling, and functional bowel disorder that significantly affects social functioning and reduces quality of life and increases social costs. The Korean Society of Neurogastroenterology and Motility published clinical practice guidelines on the management of IBS based on a systematic review of the literature in 2017, and planned to revise these guidelines in light of new evidence on the pathophysiology, diagnosis, and management of IBS. The current revised version of the guidelines is consistent with the previous version and targets adults diagnosed with or suspected of having IBS. These guidelines were developed using a combination of de novo and adaptation methods, with analyses of existing guidelines and discussions within the committee, leading to the identification of key clinical questions. Finally, the guidelines consisted of 22 recommendations, including 3 concerning the definition and risk factors of IBS, 4 regarding diagnostic modalities and strategies, 2 regarding general management, and 13 regarding medical treatment. For each statement, the advantages, disadvantages, and precautions were thoroughly detailed. The modified Delphi method was used to achieve expert consensus to adopt the core recommendations of the guidelines. These guidelines serve as a reference for clinicians (including primary care physicians, general healthcare providers, medical students, residents, and other healthcare professionals) and patients, helping them to make informed decisions regarding IBS management.
