It is reported that the orthognathic patients suffer from not only aesthetic problems but also resonance disorder and articulation disorder because of the abnormality of the oral cavity. This study was designed to investigate the resonance of nasality and the intelligibility of speech for acoustic characteristics of patients' speech before and after orthognatic surgery. 8 orthognathic patients participated in the study. The nasality of words containing Korean consonants, Korean consonants and frequency and intensity of the fricative /s/ were measured using Nasometer and CSL (Computerized Speech Lab). Results were as follows: First, the nasality of post orthognathic surgery patients decreased in spontaneous speech. There was a significant difference in the nasality for all words between pre and post orthognatic surgery patients. Second, the nasality of each Korean consonant phoneme of post orthognathic surgery patients decreased. There was also a significant difference of the nasality for each Korean consonant phoneme between pre and post orthognatic surgery patients. Third, the decreased nasality for Korean consonant phonemes showed in plosives, affricates, fricatives, liquids, and nasals after surgery. But the significant difference showed only in plosives and fricatives. Finally, frequency and intensity for the fricative /s/ of post orthognathic patients increased.
Background: The clinical characteristics of pediatric nasal fractures can vary depending on the child's age, social activities, and environment. Therefore, this study aimed to analyze these characteristics in different age groups. Methods: We retrospectively reviewed of a series of patients aged under 12 years who received treatment between 2013 and 2021. The initial study design involved dividing the patients into four age groups, corresponding to different developmental ages, but there were no cases in infants aged 0 to 1 year. Therefore, the patients were divided into three groups: group I, between 2 and 5; group II, between 6 and 9; and group III, between 10 and 12 years of age. The following parameters were evaluated: sex, age, etiology, fracture type and severity, and the incidence of septal injuries. Results: In total, 98 patients were included in this study. In group III, the ratio of boys to girls was 3.88:1, exceeding the overall ratio of 1.97:1. The most common cause varied with age: slipping down in group I, bumping accidents in group II, and sports accidents in group III. Concomitant septal injuries were present in 4.17% of patients in group I, 5.71% of patients in group II, and 28.21% of patients in group III. Conclusion: Increasing age was accompanied by a greater tendency for male predominance and a higher prevalence of sports-related causes and septal injuries. Violence was infrequent but started to become a contributing factor during school age. These varying environmental factors across age groups can offer valuable insights into the epidemiology and clinical characteristics of pediatric nasal bone fractures.
The number of patients is increasing and their mean age is also increasing. Proper dietary adjustments are necessary to prevent protein-calorie malnutrition or complications but it is difficult for dialysis patients to adapt to diet therapy due to stress or anorexia. Education does not consider the individual characteristics, knowledge, dietary inhabit education demands, and initial education. The purpose of this study was to identify dialysis patient's nutrition knowledge and, dietary practice and compare those with nutrition education or counseling demands for providing basic data of desirable nutrition management. The data were collected by a survey consisting of the general characteristics, disease related characteristics, nutrition education and counsel characteristics, level of nutrition knowledge, diet therapy, and nutrition education and counsel demands from the 28th March to 22th July 2017. The total number of subjects were 33 patients among dialysis patients at two tertiary medical institutions and an artificial kidney room at a private hospital in Incheon Gyeonggi. The data collected were analyzed statistically using the SPSS program 23.0, followed by further analyses using frequency analysis, one-way ANOVA, cross analysis, and correlation analysis. The results of the dialysis patients showed that younger (P<0.05), female (P<0.05), abnormal high school diploma (P<0.001) groups had high nutrition scores. In addition, dietary practice and nutrition education and counsel demands showed a positive correlation (P<0.05, P<0.01). In particular, females were higher than males in nutrition knowledge, dietary practice, nutrition education, and counseling demand scores.
In this study, we investigated the virological characteristics, HBV DNA levels and presence of mutations of "a" determinant in the HBsAg S gene in chronic hepatitis B patients with coexisting HBsAg and anti-HBs. The 18 patients who were diagnosed with chronic hepatitis B were both positive for HBsAg and anti-HBs. HBV Among them, 15 patients were DNA positive. The median of HBV DNA levels in serum was $2.18{\times}10^7$ copies/mL with the HBsAg+/anti-HBsAb+ patients. Also, 4 of 8 HBeAg negative patients had HBV DNA levels higher than $10^4$ copies/mL and the median of HBV DNA levels was $2.03{\times}10^6$ copies/mL, which were significantly high. These results showed that viral replication still existed in most of the patients of the concomitant HBsAg and anti-HBs, and even in the some HBeAg negative patients. Furthermore, mutation within the "a" determinant of HBV were found in 7 of 15 patients. The most frequent changes were located at positions aa126. In addition, one mutation observed for HBsAg only positive.
The coronavirus disease 2019 (COVID-19) pandemic (severe acute respiratory syndrome coronavirus 2) is a global infectious disease with rapid spread. Some patients have severe symptoms and clinical signs caused by an excessive inflammatory response, which increases the risk of mortality. In this study, we reanalyzed scRNA-seq data of cells from bronchoalveolar lavage fluids of patients with COVID-19 with mild and severe symptoms, focusing on Ab-producing cells. In patients with severe disease, B cells seemed to be more activated and expressed more immunoglobulin genes compared with cells from patients with mild disease, and macrophages expressed higher levels of the TNF superfamily member B-cell activating factor but not of APRIL (a proliferation-inducing ligand). In addition, macrophages from patients with severe disease had increased pro-inflammatory features and pathways associated with Fc receptor-mediated signaling, compared with patients with mild disease. CCR2-positive plasma cells accumulated in patients with severe disease, probably because of increased CCL2 expression on macrophages from patients with severe disease. Together, these results support the hypothesis that different characteristics of B cells might be associated with the severity of COVID-19 infection.

Purpose: Extracorporeal elimination of drugs is a critical part of managing poisonings, although the indications and optimal method remain a matter of debate. The aim of this study is to report our clinical experiences with continuous renal replacement therapy (CRRT), as performed by emergency room physicians, as method of extracorporeal drug elimination in patients with poisoning. Methods: This study was a retrospective study of the consecutive patients who underwent CRRT, as performed by an emergency room physician, for acute poisoning. The patient characteristics, the kinds of drugs and the method of extracorporeal elimination were analyzed by reviewing the patients' charts. Results: During eleven months, 26 patients with acute poisoning underwent extracorporeal elimination (2 patients; intermittent hemodialysis, 24 patients; CRRT). The mean time from the decision to performing extracorporeal elimination was $206.0{\pm}36.8$ minutes for intermittent hemodialysis, $62.9{\pm}8.5$ minutes for continuous venoveno-hemodiafiltration (CVVHDF) and $56.6{\pm}6.8$ minutes for charcoal hemoperfusion. For the patients with CRRT, CVVHDF was conducted in 10 patients (3 patients; valproic acid, 2 patients; Lithium, 1 patient; salicylates, 1 patient; methanol) and charcoal hemoperfusion by using CRRT was done in 14 patients (13 patients; paraquat, 1 patient; dapsone). For the 12 patients who required hemodialysis due to severe poisoning, 7 patients underwent CRRT because of their unstable vital signs. Conclusion: CRRT was an effective method of extracorporeal drug elimination in patients with acute poisoning, and especially for the cases with unstable vital sign and for those patients who required an early start of extracorporeal elimination according to the characteristics of the drug. (ED note: the writing of the abstract was not clear. Check it carefully.)
Background and Objectives: Obesity is one of the most important risk factors for obstructive sleep apnea (OSA). There is limited evidence regarding the obesity-related anthropometric characteristics of Korean patients. Materials and Method: Medical records of 984 patients referred to 3 tertiary referral hospitals for habitual snoring or sleep apnea were analyzed. We defined OSA as apnea-hypopnea index (AHI) ${\geq}5$ and analyzed data to determine the anthropometric characteristics of patients with OSA such as neck circumference (NC), waist circumference (WC), hip circumference (HC), and waist to hip ratio (WHR). Results: A total of 952 patients (719 men) were included in the analysis. The main findings were: 1) BMI, WC, NC, HC, and WHR were greater among patients with OSA than among controls (AHI <5); 2) for both sexes, the proportion of patients with an OSA diagnosis increased with age; it increased steeply for women aged >50 years; 3) WC and WHR were most strongly correlated with AHI for men and women, respectively. Conclusion: OSA is associated with anthropometric characteristics, although different patterns were observed between men and women. OSA was more strongly associated with NC or WC among men and with WHR among women.

Purpose: The relationship between the staff area and the patient's private area is the key factor in designing the structure and the environmental characteristics of ward spaces in a psychiatric hospital. Recent research has found that for the purpose of treatment and securing privacy, psychiatric patients need to be in an open space of relief rather than closed confined environment and under the watch of nursing staffs. Methods: A survey at three kinds of wards in a private psychiatric hospital in Japan was conducted in October 2002. These wards include an acute ward, a psychiatric convalescence ward, and a stress care ward. All three kinds of wards have the same structure. At each ward, spatial preferences of the 145 psychiatric inpatients were surveyed and data concerning the patient's diagnostic category, symptoms, and activities of daily living were recorded. Results: The patients in the stress care ward prefer to stay in private spaces than public spaces. On the other hand, in the acute ward the patients seem to have a preference between managed public spaces where are monitored by nursing staffs and their private rooms where the nurse station is close. In addition, the patients in the psychiatric convalescence ward spend most of their time in the public space, such as the hallways or the day room. Implications: Base on this research, the spaces at the acute ward that could be monitored by the nursing station serves effectively as a safety space for patients was concluded. However, in the stress care ward, the patients may perceive the monitoring by the nursing staff as interruption or nuisance to their relaxation. In order to design an ideal healing environment for psychiatric patients in psychiatric ward, it is important to consider how environmental characteristics of space affect the environmental sense of patients in each ward.

Purpose: This study examined the clinical and epidemiological characteristics of intensive care unit (ICU) patients admitted or died in the emergency medical center with acute-poisoning to investigate the variables related to the prognosis. Methods: The data were collected from poisoning patients admitted or died in the emergency medical center of a general hospital located in Seoul, from January 2014 to February 2020. The subjects of this study were 190 patients. The medical records were screened retrospectively, and the clinical and epidemiological characteristics of the patients in the emergency room (ER) and ICU were examined to investigate the contributing factors that influence the poor prognosis. Results: The study analyzed 182 patients who survived after being admitted to the intensive care unit (ICU). The results are as follows. The mental change (87.4%) was the most common symptom. Sedative poisoning (49.5%) was the commonest cause. For most patients, pneumonia (26.9%) was the most common complication. Hypotension (23.7%), tachycardia (42.1%), fever (15.8%), seizures (10.5%), dyspnea (2.6%), high poisoning severity score (PSS), type of toxic material, mechanical ventilator application (39.5%), inotropes application (39.5%), and pneumonia (55.3%) were correlated the LOS over 5 days in the ICU. 8 patients died. In the case of death pesticides and carbon monoxide were the main toxic materials; tachycardia, bradycardia, and hypotension were the main symptoms, and a mechanical ventilator and inotropes were applied. Conclusion: Patients with unstable vital signs, high PSS, and non-pharmaceutical poisoning had a prolonged LOS in the ICU and a poor prognosis.

Submucosal type cleft palate is subdivision of the cleft palate. It is very difficult to find submucosal cleft, because when we exam submucosal type cleft palate patients, it seems to be normal. But in fact, there are abnormal union of palatal muscles of submucosal type cleft palate patients. Because of late detection, the treatment - for example, the operation or the speech therapy - for the submucosal type cleft palate patient usually becomes late. Some patients visited our hospital due to speech disorder nevertheless normal intraoral appearance. After precise intraoral examination, we found out submucosal cleft palate. We evaluated the speech before and after surgery of these patients. In this study, we want to find the objective characteristics of submucosal type cleft palate patients, comparing with the normal and the complete cleft palate patients. Experimental groups were 10 submucosal type cleft palate patients and 10 complete cleft palate patients who got the operation in our hospital. And, the controls were 10 normal person. The sentence patterns using in this study were simple 5 vowels. Using CSL program we evaluated the Formant, Bandwidth. We analized the spectral characteristics of speech signals of 3 groups, before and after the operation. In most cases, the formant scores were higher in experimental groups (complete cleft palate group and submucosal type cleft palate group) than controls. There were small differences when speeching /a/, /i/, /e/ between experimental groups and control groups, large differences when speeching /o/, /u/. After surgery the formant scores were decreased in experimental groups (complete cleft palate group and submucosal type cleft palate group). In bandwidth scores, there were no significant differences between experimental groups and controls.
