A food exchange list is a tool developed to help diabetic patients control their energy intake and plan balanced meals. Korean food exchange lists were first developed in 1988, revised in 1995, and updated again in 2010. With rapidly changing dietary habits and increasing demand for diverse food cultures, the Korean Diabetes Association in cooperation with 4 related organizations established a Task Force Team (TFT) to revise food exchange lists in March 2022.

To assess the response to monocular occlusion test in basic type intermittent exotropia (IXT) and to evaluate the surgical outcomes of titrated surgery based on the test's result. Medical records were retrospectively reviewed for patients who underwent bilateral lateral rectus recession for basic type IXT. Patients were categorized into two groups: those who underwent a preoperative diagnostic monocular occlusion test (occlusion group) and those who did not (no occlusion group).

The upper head of the lateral pterygoid muscle (LPM) is known to insert into the capsule of the temporomandibular joint and articular disc, and therefore its relationship with temporomandibular disorders (TMD) has been consistently suggested. The aim of the study was to determine the anatomical features of the LPM using ultrasonographic (US) imaging. Around 120 hemifaces from 60 healthy Korean volunteers were included in this study.

Obstructive sleep apnea (OSA) is closely associated with the development and chronicity of temporomandibular disorder (TMD). Given the intricate pathophysiology of both OSA and TMD, comprehensive diagnostic approaches are crucial. This study aimed to develop an automatic prediction model utilizing multimodal data to diagnose OSA among TMD patients.

This study investigated the usefulness of deep learning-based automatic detection of temporomandibular joint (TMJ) effusion using magnetic resonance imaging (MRI) in patients with temporomandibular disorder and whether the diagnostic accuracy of the model improved when patients' clinical information was provided in addition to MRI images. The sagittal MR images of 2948 TMJs were collected from 1017 women and 457 men (mean age 37.19 ± 18.

Quercetin (QC), a naturally occurring bioflavonoid found in various fruits and vegetables, possesses many potential health benefits, primarily attributed to its robust antioxidant properties. The generation of oxidative stress in bone cells is a key modulator of their physiological behavior. Moreover, oxidative stress status influences the pathophysiology of mineralized tissues.

Article Synopsis
  • The study compares oral health conditions and serological characteristics of patients with rheumatoid arthritis (RA) and osteoarthritis (OA) against healthy controls, highlighting significant differences, particularly in the prevalence of periodontal diseases and xerostomia.
  • Participants included 161 individuals divided into normal, OA, and RA groups, with RA further categorized into seronegative (snRA) and seropositive (spRA) subtypes.
  • Key findings show OA patients had a 100% prevalence of periodontal disease, while RA patients showed a high occurrence of xerostomia (84.5%), indicating distinct oral health issues between the two arthritis types and their relationship to diagnosis.

Xerostomia may be accompanied by changes in salivary flow rate and the incidence increases in elderly. We aimed to use machine learning algorithms, to identify significant predictors for the presence of xerostomia. This study is the first to predict xerostomia with salivary flow rate in elderly based on artificial intelligence.

Background/objectives: We investigated the clinical features and change in incidence of AACE in South Korea.

Subjects/methods: We reviewed the medical records of AACE patients who visited the Strabismus Clinic of at a tertiary referral hospital from 2007 to 2021. Clinical features were retrieved, including age at onset, angle of deviation, refractive errors, neuroimaging findings, and treatment outcomes.

Fascial space abscess is a condition in which infections spread into fascial spaces. It is a severe and life-threatening disease unless treated at an early stage. Due to the similarity of clinical symptoms, fascial space abscesses in the orofacial area are often disguised as other diseases, such as temporomandibular disorder (TMD).

Background: We aimed to investigate the effects of a nonviolent and nonverbal communication and self-acceptance training program among Korean nursing students.

Methods: We enrolled students in nursing departments at three universities in Busan Metropolitan City, South Korea. The students were randomly allocated to the experimental (n = 38) and control groups (n = 36); subsequently, they completed questionnaires before and after training.

NA4/NA6, an intermediate degradation product of β-agarase, is a high value-added product with anticancer, anti-obesity, and anti-diabetic effects. Therefore, a method that enables the efficient production of NA4/NA6 would be useful from economic and medical perspectives. In this study, we aimed to generate a Streptomyces coelicolor A3(2) mutant M22-2C43 that produces NA4/NA6 as a final product; this method serves as a more efficient alternative to the enzymatic conversion of β-agarase for the generation of these products.

  • Urinary tract infections (UTIs) are frequent bacterial infections in young children and can lead to hospitalization, particularly in those under 24 months.
  • A study reviewed data from 2,141 pediatric patients with febrile UTI to explore the clinical features and factors predicting bacteremia, finding that 1.9% had bacteremia, mostly in infants aged 6 months and younger.
  • Key risk factors for bacteremia included younger age, lower blood lymphocyte counts and serum albumin, and higher levels of C-reactive protein and blood urea nitrogen, with the BUN/albumin ratio being a new predictive marker.

Objective: Halitosis or oral malodor is an unpleasant odor from the oral cavity. However, although patients with periodontitis often complain of halitosis, their relationship has not been fully elucidated. We reviewed previous literature based on the hypothesis that the relationship between halitosis and periodontitis is mediated by the oral microbiome.

The production of β-lactamase by nontyphoidal has become a public health issue throughout the world. In this study, we aimed to investigate the antimicrobial resistance profiles and molecular characteristics of β-lactamase-producing serovar Albany isolates. A total of 434 Albany were obtained from feces and carcasses of healthy and diseased food-producing animals [cattle ( = 2), pigs ( = 3), chickens ( = 391), and ducks ( = 38)] during 2013-2020.

  • This study investigated the relationship between volatile sulfur compounds (VSCs) and halitosis in patients with gingivitis and periodontitis, comparing them to healthy controls.
  • Results showed significantly higher VSC levels (especially hydrogen sulfide and methyl mercaptan) in patients with gingivitis compared to healthy individuals, indicating an association with oral diseases.
  • Halitosis was more prevalent in those with gingivitis (39.5%) and periodontitis (42.9%) than in healthy subjects (3%), with periodontal disease being a significant predictor of halitosis occurrence.
