Background: This study analyzed the practice of dental medical dispute prevention rules of dental hygienists to present an improvement plan for improving perceived importance and practice and provide data for the development of effective medical dispute prevention programs. Methods: A self-administered questionnaire survey was conducted targeting dental hygienists who were providing assistance at dental hospitals and dental clinics in Seoul and Gyeonggi-do regions from March 22 to April 28, 2022. The questionnaire collected from 273 dental hygienists consisted of eight questions on general characteristics, 30 questions on medical dispute experience, and 14 questions on medical dispute prevention. Results: Complaints showed a high experience rate in ‘Consultation & reservation’, medical disputes in ‘Patient handling (unkind) related’, and ‘Prosthesis installation and cement removal’. In both the importance and practice of medical dispute prevention rules, Preservation of medical records and other medical-related data’ was high, and ‘Management of patients on standby for a long time’was low in terms of practice. ‘Lack of time’ and ‘Lack of manpower’ were cited as reasons for not resolving dental treatment disputes. The importance of dental dispute prevention rules was found to be significant according to age and position, and it was also found to affect the level of practice. Conclusion Seventy-six-point six percent of the respondents said that education on the prevention of medical disputes was necessary, although they lacked recognition of prevention rules compared to their perceptions and experiences. This study suggested specifying prevention rules in dental hygiene subjects and expanding education, improvement of dental treatment system, revise the law on the range of work to improve the recognition and practice of prevention rules.

Near-infrared spectroscopy is a device used to determine whether traumatic intracranial hemorrhage has occurred and is primarily used for screening in emergency situations. In this study we examined the applicability of this equipment in postmortem inspection. This study included 124 autopsy cases and 59 postmortem inspection cases performed in the National Forensic Service from July 2017 to October 2018. We carried out the test using Infrascanner Model 2000 (Infrascan Inc.). Autopsy cases were divided into four groups (epidural hemorrhage or subdural hemorrhage group, traumatic subarachnoid hemorrhage or cerebral contusion group, nontraumatic intracerebral hemorrhage group, and control group) and analyzed. There was no difference in the test results according to the presence and type of intracranial hemorrhage. The possibility that variables related to postmortem change affected the test results was considered. In conclusion, this study confirmed that near-infrared spectroscopy is not suitable for the detection of traumatic intracranial hemorrhage in postmortem inspection.

BACKGROUND: Woake's syndrome (WS) is a recurrent nasal polyposis, accompanied by broadening of the nose, frontal sinus aplasia, dyscrinia, and bronchiectasis. There has been no previous report on anesthetic management in patients with WS. CASE: We describe a case involving a 13-year-old male patient with WS who was scheduled for septorhinoplasty for necrotic ethmoiditis. Anesthesia was induced and maintained with propofol and remifentanil using a target-controlled infusion device. The anesthetic considerations of this rare syndrome and the advantages of an intravenous infusion method over local and volatile anesthesia for these patients are discussed. We report on caveats, such as pulmonary dysfunction during the anesthetic management, and nasal structural problems encountered in WS patients. CONCLUSIONS: Given that conventional inhaled anesthesia reduces ciliary movement and that local anesthesia with sedative has several disadvantages, perioperative control and precautions against respiratory infections by using antibiotics, and preventing cilio-depressant actions, are important for anesthetic management.

BACKGROUND: Korea's population is aging rapidly. Aged people who lead a solitary life are in a state of social isolation and face a greater risk of lower quality of life. The purpose of this study was to analyze the health behaviors and lifestyle patterns of aged people who lead a solitary life in Korea.METHODS: We analyzed 4,471 subjects (1,933 men and 2,538 women)-aged people aged 65 or above-based on data from the Korea National Health and Nutrition Examination Survey VI (2013–2015). The odds ratios (ORs) and 95% confidence intervals (CIs) were analyzed using multivariate logistic regression analysis adjusted with age, household income level, occupational status, and geographical region.RESULTS: Socioeconomic status was lower in aged people who lead a solitary life than in those living with family. The ORs for frequent eating out alone (OR=2.93; 95% CI 1.83–4.38), daily eating out alone (OR=2.40; 95% CI 1.25–4.60), smoking (OR=1.57; 95% CI 1.06–2.32), feeling sick or uncomfortable (OR=1.59; 95% CI 1.08–2.36), feeling depressed (OR=4.10; 95% CI 2.53–6.65), and suicide ideation (OR=2.06; 95% CI 1.21–3.51) were significantly higher in male subjects who lead a solitary life. The ORs for frequent eating out alone (OR=1.57; 95% CI 1.10–2.24) and inadequate sleep duration (OR=1.29; 95% CI 1.03–1.61) were significantly higher in female subjects who lead a solitary life.CONCLUSION: Aged people who lead a solitary life exhibited unhealthy behaviors and poor mental health. The elderly men who lead a solitary life faced higher risk of poor health than the women. Integrated management of lifestyle behaviors is required to improve the quality of health in aged people who lead a solitary life.

CHARGE syndrome is a rare genetic disorder with CHD7 gene mutation. CHARGE is an acronym for coloboma (C), heart disease (H), atresia of choanae (A), retardation of growth (R), genitourinary malformation (G), and ear abnormalities (E). Patients with CHARGE syndrome need to undergo many surgeries due to their various congenital anomalies. Since airway abnormalities frequently accompany CHARGE syndrome, general anesthesia remains a challenge. Here we report a case of difficult intubation in a 35-month-old boy with CHARGE syndrome during general anesthesia and the experience of successful intubation using D-blade of C-MAC® video laryngoscope.

OBJECTIVE: Considering the different prevalence rates of diseases such as asthma and chronic obstructive pulmonary disease in Asians relative to other races, Koreans may have unique airway structure and lung function. This study aimed to investigate unique features of airway structure and lung function based on quantitative computed tomography (QCT)-imaging metrics in the Korean Asian population (Koreans) as compared with the White American population (Whites). MATERIALS AND METHODS: QCT data of healthy non-smokers (223 Koreans vs. 70 Whites) were collected, including QCT structural variables of wall thickness (WT) and hydraulic diameter (Dh) and functional variables of air volume, total air volume change in the lung (ΔVair), percent emphysema-like lung (Emph%), and percent functional small airway disease-like lung (fSAD%). Mann-Whitney U tests were performed to compare the two groups. RESULTS: As compared with Whites, Koreans had smaller volume at inspiration, ΔVair between inspiration and expiration (p < 0.001), and Emph% at inspiration (p < 0.001). Especially, Korean females had a decrease of ΔVair in the lower lobes (p < 0.001), associated with fSAD% at the lower lobes (p < 0.05). In addition, Koreans had smaller Dh and WT of the trachea (both, p < 0.05), correlated with the forced expiratory volume in 1 second (R = 0.49, 0.39; all p < 0.001) and forced vital capacity (R = 0.55, 0.45; all p < 0.001). CONCLUSION: Koreans had unique features of airway structure and lung function as compared with Whites, and the difference was clearer in female individuals. Discriminating structural and functional features between Koreans and Whites enables exploration of inter-racial differences of pulmonary disease in terms of severity, distribution, and phenotype.

Arthrogryposis-renal dysfunction-cholestasis (ARC) syndrome is a rare autosomal recessive multisystemic disease that is associated with the liver, kidney, skin, and central nervous and musculoskeletal systems. ARC occurs as a result of mutations in the VPS33B (Vacuolar protein sorting 33 homolog B) or VIPAR (VPS33B interacting protein, apical-basolateral polarity regulator) genes. A female infant presented with neonatal cholestasis with a severe clinical outcome. She was diagnosed with ARC syndrome using targeted exome sequencing (TES). Exome sequencing revealed compound heterozygous mutations, c.707A>T and c.239+5G>A, in VPS33B, where c.707A>T was a novel variant; the resultant functional protein defects were predicted via in silico analysis. c.239+5G>A, a pathogenic mutation that affects splicing, is found in less than 0.1% of the general population. Invasive techniques, such as liver biopsies, did not contribute to a differential diagnosis of ARC syndrome; thus, early TES together with clinical presentations constituted an apparently accurate diagnostic procedure.
