Objectives:
Children and adolescents have a high prevalence of dental caries, primarily due to negligent oral care, frequent snack intake, and inadequate attention to oral disease prevention.Therefore, ensuring oral care and preventing dental caries during this period is essential. Economic barriers, particularly in low- and middle-income countries like the Philippines, limit access to dental care, highlighting the need for national oral health programs.
Methods:
This study aimed to investigate the oral health status of children in selected areas of the Philippines and to generate basic data for effective oral health promotion programs. We compared the oral health statuses of enrolled and newly enrolled students in schools with school-based dental clinics.
Results:
The results indicated that the prevalence of caries and the average number of carious permanent teeth were lower in enrolled students than in new students.
Conclusions
This finding suggests that school-based oral healthcare programs effectively improve children’s oral health and that introducing school-based dental clinics and establishing efficient systems are essential for improving oral health in low- and middle-income countries.

Background/Aims:
We aim to investigate the diagnostic accuracy and differences between Chicago classification version 3.0 (CC v3.0) and 4.0 (CC v4.0).
Methods:
Patients who underwent high-resolution esophageal manometry (HRM) for suspected esophageal motility disorders were prospectively recruited between May 2020 and February 2021. The protocol of HRM studies included additional positional change and provocative testing designed by CC v4.0.
Results:
Two hundred forty-four patients were included. The median age was 59 (interquartile range, 45-66) years, and 46.7% were males.Of these, 53.3% (n = 130) and 61.9% (n = 151) were categorized as normalcy by CC v3.0 and CC v4.0, respectively. The 15 patients diagnosed of esophagogastric junction outflow obstruction (EGJOO) by CC v3.0 was changed to normalcy by position (n = 2) and symptom (n = 13) by CC v4.0. In seven patients, the ineffective esophageal motility (IEM) diagnosis by CC v3.0 was changed to normalcy by CC v4.0. The diagnostic rate of achalasia increased from 11.1% (n = 27) to 13.9% (n = 34) by CC v4.0. Of patients diagnosed IEM by CC v3.0, 4 was changed to achalasia based on the functional lumen imaging probe (FLIP) results by CC v4.0. Three patients (2 with absent contractility and 1 with IEM in CC v3.0) were newly diagnosed with achalasia using a provocative test and barium esophagography by CC v4.0.
Conclusions
CC v4.0 is more rigorous than CC v3.0 for the diagnosis of EGJOO and IEM and diagnoses achalasia more accurately by using provocative tests and FLIP. Further studies on the treatment outcomes following diagnosis with CC v4.0 are needed.

Purpose:
This study attempted to develop clinical guidelines to help patients use hospice and palliative care (HPC) at an appropriate time after writing physician orders for lifesustaining treatment (POLST) by identifying the characteristics of HPC use of patients with terminal cancer.
Methods:
This retrospective study was conducted to understand the characteristics of HPC use of patients with terminal cancer through decision tree analysis. The participants were 394 terminal cancer patients who were hospitalized at a cancer-specialized hospital in Seoul, South Korea and wrote POLST from January 1, 2019 to March 31, 2021.
Results:
The predictive model for the characteristics of HPC use showed three main nodes (living together, pain control, and period to death after writing POLST). The decision tree analysis of HPC use by terminal cancer patients showed that the most likely group to use HPC use was terminal cancer patients who had a cohabitant, received pain control, and died 2 months or more after writing a POLST. The probability of HPC usage rate in this group was 87.5%. The next most likely group to use HPC had a cohabitant and received pain control; 64.8% of this group used HPC. Finally, 55.1% of participants who had a cohabitant used HPC, which was a significantly higher proportion than that of participants who did not have a cohabitant (1.7%).
Conclusion
This study provides meaningful clinical evidence to help make decisions on HPC use more easily at an appropriate time.

BACKGROUND/OBJECTIVES:
Given the increasing proportion of the Korean population that is aged 65 years and older, the present study analyzed the relationship between diet quality and sarcopenia in elderly persons by using data from the 2008–2011 Korea National Health and Nutrition Examination Survey (KNHANES).
SUBJECTS/METHODS:
Data for 3,373 persons aged 65 years and over (men: 1,455, 43.1%) were selected from the 2008–2011 KNHANES. Sarcopenia assessments are based on a formula that divides a subject's appendicular skeletal muscle mass (ASM) by their weight (wt) and multiplies that result by 100 ([ASM/wt] × 100). Sarcopenia is present if the subject's result was less than one standard deviation (SD) below the sex-specific mean for a young reference group. For evaluation of diet quality, data obtained via the 24-hour recall method were used to calculate the Diet Quality Index for Koreans (DQI-K). A general linear model was applied in order to analyze general information and nutritional intake according to sarcopenia status. For analysis of the relationship between diet quality and sarcopenia, a binominal logistic regression analysis was undertaken.
RESULTS:
The sarcopenia prevalence rate among the study subjects aged 65 years and over was 37.6%. The DQI-K of those without sarcopenia was 3.33 ± 0.04 points, while that of those with sarcopenia was 3.45 ± 0.04 points (P < 0.05). The relationship between diet quality and sarcopenia revealed that subjects aged 75 and older had a poor diet quality, and their odds ratio (OR) of sarcopenia presence was significantly higher (OR: 1.807, 95% confidence interval: 1.003–3.254, P < 0.05).
CONCLUSIONS
This study revealed that poor diet quality was related to sarcopenia presence in Koreans aged 75 and older. In order to improve the diet quality of the elderly (aged 75 and older), it is necessary to develop dietary improvement guidelines.

Purpose:
The association of the initial serum ammonia level with in-hospital mortality in patients with acute glufosinate-ammonium herbicide poisoning was studied.
Methods:
This retrospective cohort study was conducted between March 2012 and August 2019 in the emergency department after glufosinate-ammonium herbicide poisoning. Survivors and non-survivors were analyzed using a Mann-Whitney U test and Fisher’s exact test. Multivariate logistic regression analysis was performed to determine the independent risk factors for mortality.
Results:
One hundred and six patients were enrolled; 11 died, yielding a mortality of 10.4%. The serum bicarbonate level was significantly lower in the non-survival group than the survival group. Age, serum ammonia, blood urea nitrogen, creatinine levels, SOFA score, and APACHE II score were significantly higher in the non-survival group than the survival group. Age, serum ammonia, and creatinine level were independent risk factors for mortality in multivariate logistic regression analysis.
Conclusion
The initial serum ammonia level is associated with mortality in patients with acute glufosinate herbicide poisoning.

BACKGROUND: In the present multi-institutional study, the prevalence and clinicopathologic characteristics of non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) were evaluated among Korean patients who underwent thyroidectomy for papillary thyroid carcinoma (PTC).METHODS: Data from 18,819 patients with PTC from eight university hospitals between January 2012 and February 2018 were retrospectively evaluated. Pathology reports of all PTCs and slides of potential NIFTP cases were reviewed. The strict criterion of no papillae was applied for the diagnosis of NIFTP. Due to assumptions regarding misclassification of NIFTP as non-PTC tumors, the lower boundary of NIFTP prevalence among PTCs was estimated. Mutational analysis for BRAF and three RAS isoforms was performed in 27 randomly selected NIFTP cases.RESULTS: The prevalence of NIFTP was 1.3% (238/18,819) of all PTCs when the same histologic criteria were applied for NIFTP regardless of the tumor size but decreased to 0.8% (152/18,819) when tumors ≥1 cm in size were included. The mean follow-up was 37.7 months and no patient with NIFTP had evidence of lymph node metastasis, distant metastasis, or disease recurrence during the follow-up period. A difference in prevalence of NIFTP before and after NIFTP introduction was not observed. BRAF(V600E) mutation was not found in NIFTP. The mutation rate for the three RAS genes was 55.6% (15/27).CONCLUSIONS: The low prevalence and indolent clinical outcome of NIFTP in Korea was confirmed using the largest number of cases to date. The introduction of NIFTP may have a small overall impact in Korean practice.

KBG syndrome is an autosomal dominant syndrome presenting with macrodontia, distinctive facial features, skeletal anomalies, and neurological problems caused by mutations in the ankyrin repeat domain 11 (ANKRD11) gene. The diagnosis of KBG is difficult in very young infants as the characteristic macrodontia and typical facial features are not obvious. The youngest patient diagnosed to date was almost one year of age. We here describe a 2-month-old Korean boy with distinctive craniofacial features but without any evidence of macrodontia due to his very early age. He also had a congenital megacolon without ganglion cells in the rectum. A de novo deletion of exons 5–9 of the ANKRD11 gene was identified in this patient by exome sequencing and real-time genomic polymerase chain reaction. As ANKRD11 is involved in the development of myenteric plexus, a bowel movement disorder including a congenital megacolon is not surprising in a patient with KBG syndrome and has possibly been overlooked in past cases.

PURPOSE:
The purpose of this study was to determine the most appropriate shelf life for sterilized products according to their packaging material.
METHODS:
Samples were prepared to target six nursing units in one general hospital in Seoul. After steam and E.O gas sterilization, sterilized product, samples were supplied to wards. Data collection was conducted for 3 months, after the expiration date of 3 months had passed for samples packaged with crepe paper and nonwoven wraps. For samples packaged with paper-plastic pouches, data collection conducted for 3 months when the expiration date of 9 months had passed. The sterilized products were collected and tested for microbial contamination. Identification of the storage environment was done as samples were collected.
RESULTS:
This study confirmed that the storage environment met international standards such as CDC, except for temperature. For steam sterilized crepe paper packaging samples and steam and E.O gas sterilized for nonwoven packaging samples no contamination in all products was found for 3 months past the expiration date. However, in the E.O gas sterilized paper-plastic pouch packaging sterile samples, Gram-positive bacilli were detected in one sample from a surgical intensive care unit at 45 weeks and another sample from an operating room at 47 weeks. Furthermore, the results did not show any microorganisms for up to 52 weeks in all products.
CONCLUSION
According to the results of this study, sterilized product packaging made with crepe paper and nonwoven wraps is better able an extended shelf life from 3 months to 6 months, reducing unnecessary costs.
