Purpose:
We assessed the proportion of patients with a focal intrahepatic stricture (FIHS) that was a precursor lesion or malignancy and visualized only as a duct dilatation.
Materials and Methods:
This retrospective study assessed patients who underwent surgery or biopsy for an FIHS on CT or MRI between January 2010 and March 2022. The number and proportion of non-precursor benign lesions, precursors, and malignancies were calculated.Clinical variables and imaging features were compared between non-premalignant benign and premalignant/malignant FIHSs.
Results:
Twenty-eight patients with confirmed histopathological diagnoses were identified, including 15 men (54.0%) and 13 women (46.0%). The median age of all patients at the first imaging diagnosis was 65 ± 9.54 (range, 43–78) years. Of the 28 patients with FIHSs, 9 (32%) were diagnosed with cholangiocarcinoma and 7 (25%) were diagnosed with precursor lesions, which included six intraductal papillary neoplasms of the bile duct and one biliary intraepithelial neoplasm. Accordingly, 16 (57%) patients had malignant or precursor lesions, and 12 (43%) were diagnosed with non-precursor benign lesions. None of the clinical variables and imaging features used for analysis showed a statistically significant difference between the non-premalignant benign and premalignant/malignant FIHS groups (p > 0.05).
Conclusion
FIHSs visualized only as duct dilatation can harbor malignant or precursor lesions.

Nutrition Research and Practice 2021;15(2):213-224
BACKGROUND/OBJECTIVES:
To evaluate the nutritional status and prevalence of malnutrition in hospitalized children at admission and during hospitalization in South Korea.
SUBJECTS/METHODS:
This first cross-sectional nationwide “Pediatric Nutrition Day (pNday)” survey was conducted among 872 hospitalized children (504 boys, 368 girls; 686 medical, 186 surgical) from 23 hospitals in South Korea. Malnutrition risk was screened using the Pediatric Yorkhill Malnutrition Score (PYMS) and the Screening Tool Risk on Nutritional status and Growth. Nutritional status was assessed by z-scores of weight-for-age for underweight, weight-for-height for wasting, and height-for-age for stunting as well as laboratory tests.
RESULTS:
At admission, of the 872 hospitalized children, 17.2% were underweight, and the prevalence of wasting and stunting was 20.2% and 17.3%, respectively. During hospitalization till pNday, 10.8% and 19.6% experienced weight loss and decreased oral intake, respectively.During the aforementioned period, fasting was more prevalent in surgical patients (7.5%) than in medical patients (1.6%) (P < 0.001). According to the PYMS, 34.3% and 30% of the children at admission and on pNday, respectively, had a high-risk of malnutrition, requiring consultation with the nutritional support team (NST). However, only 4% were actually referred to the NST during hospitalization.
CONCLUSIONS
Malnutrition was prevalent at admission and during hospitalization in pediatric patients, with many children experiencing weight loss and poor oral intake. To improve the nutritional status of hospitalized children, it is important to screen and identify all children at risk of malnutrition and refer malnourished patients to the multidisciplinary NST for proper nutritional interventions.

Journal of Rhinology 2021;28(3):180-185
Nasal septal perforation (NSP) is a common complication of nasal surgery and can cause nasal obstruction, crust, and epistaxis. Many surgical methods have been introduced for repair of NSP, among which mucosal flap and artificial dermis have been widely used. However, mucosal graft can shrink and migrate and is difficult to fix at the perforation site. Mucosal advancement flap requires a wide extent of septal mucosa dissection, and artificial dermis can cause nasal obstruction because of its bulkiness and lower biocompatibility than autologous mucosa. To overcome these problems, we reported successful outcomes in 4 cases of small NSP by free mucosal graft with bioscaffold.

Journal of Minimally Invasive Surgery 2020;23(3):126-133
Purpose:
Remote access thyroid surgery using a bilateral axillary breast approach (BABA) or a transoral endoscopic thyroidectomy vestibular approach (TOETVA) are increasingly performed worldwide. In the Caucasus, these methods were first applied in the Republic of Georgia. This study compares these two methods of endoscopic thyroid surgery performed on patients in a tertiary hospital in Tbilisi, Georgia.
Methods:
Between December 2015 and January 2018, 41 patients underwent endoscopic thyroid surgery at the Aversi Clinic, including 32 who underwent BABA endoscopic thyroidectomy for benign nodules and nine who underwent TOETVA for thyroid cancers. Patients’ medical records were retrospectively reviewed.
Results:
Tumors were significantly larger (2.38±0.38 cm versus 1.70±0.31 cm, p value <0.001), operation time was significantly longer (177.66±21.02 min versus 116.66±5.59 min, p value <0.001), and blood loss was significantly greater (149.07±28.10 ml versus 102.22±8.33 ml, p value <0.001) in patients who underwent BABA than TOETVA. There were no significant differences in postoperative complications between the two groups.
Conclusion
Remote access thyroid surgery, either BABA or TOETVA, was successfully started, without harmful complications, at the Aversi Clinic in Tbilisi, Georgia. BABA is suitable for large sized benign nodules and TOETVA for thyroid cancers with central lymph node dissection.

The Committee on Pediatric Obesity of the Korean Society of Pediatric Gastroenterology, Hepatology and Nutrition newly developed the first Korean Guideline on the Diagnosis and Treatment of Obesity in Children and Adolescents to deliver an evidence-based systematic approach to childhood obesity in South Korea. The following areas were systematically reviewed, especially on the basis of all available references published in South Korea and worldwide, and new guidelines were established in each area with the strength of recommendations based on the levels of evidence: (1) definition and diagnosis of overweight and obesity in children and adolescents; (2) principles of treatment of pediatric obesity; (3) behavioral interventions for children and adolescents with obesity, including diet, exercise, lifestyle, and mental health; (4) pharmacotherapy; and (5) bariatric surgery.

PURPOSE: To determine the occurrence of COX-2 methylation in gastric carcinoma (GC), the status and level of CpG methylation in the promoter region of cyclooxygenase-2 (COX-2) were analyzed in early and advanced GCs, as well as in normal gastric tissues. METHODS: The extent of promoter methylation of the COX-2 gene was assessed quantitatively using pyrosequencing in 60 early and 60 advanced GCs samples harvested upon gastrectomy, and 40 normal gastric mucosa samples from patients with benign gastric diseases as controls. RESULTS: The methylation frequency for the COX-2 gene was significantly higher in early than in advanced GCs (40.0% vs. 20.0%, P < 0.05). A significant difference was found in COX-2 methylation between GCs and normal gastric tissues (30.0% vs. 10.0%, by PS; P < 0.05). COX-2 gene methylation was significantly associated with the depth of invasion (P = 0.003), lymph node metastasis (P = 0.009), distant metastasis (P = 0.036), and TNM staging (P = 0.007). The overall survival of patients with COX-2 methylation was significantly lower than that of patients without COX-2 methylation (P = 0.005). CONCLUSION: These results demonstrated that COX-2 promoter methylation was significantly higher in tumor tissues, and was an early event for GC, thus, COX-2 gene methylation may be important in the initial development of gastric carcinogenesis. Thus, GCs with methylation in COX-2 may not be good candidates for treatment with COX-2 inhibitors. Furthermore, COX-2 methylation could be a significant prognostic factor predicting a favorable effect on GC patient outcome when downregulated.
