Objectives: This study investigated the relevance of dietary behavior and oral management for oral heath in adults to extend the recognition of the importance of food intake in oral health and to provide basic information for oral health management. Methods: A survey and clinical assessment were conducted for 119 adults over 20 years of age. The chi-square test and logistic regression analysis were carried out using SPSS Statistics 20.0. Results: Gingivitis was influenced less when ham and sausage in the sub-area of meat, fish, egg, and bean were consumed once a week rather than the cases when consumed rarely (3.47 times) or when consumed two times or more a week (7.87 times) (p<0.05). Periodontitis was influenced more in the groups of 30s and 40s age than in that of over 50 years of age (14.97 times, 7.73 times) and in the group without drinking experience than in group with that (4.17 times) (p<0.05). Conclusions: The results verified the close relationship between food intake frequency and oral health in patients with periodontitis and gingivitis. Thus, it would be necessary to study the relationship between dietary behavior and oral health continuously.

Iota carrageenan-containing surimi was refrigerated for 7 days to investigate the change in its properties. Physical properties, color differences, and sensory evaluation were tested for analysis after addition of 0-3 Wt% iota carrageenan. In unheated surimi, the 2% carrageenan- containing surimi had higher chromaticity and color difference compared to the surimi without added carrageenan. However, the surimi with 3% iota carrageenan showed enhanced yellowness, resulting in a modified color difference. Surimi containing iota carrageenan showed the same trend in color difference in heated surimi after storage for 7 days, particularly when carrageenan content was 2% or greater. The hardness, gumminess, and chewiness of the heated Iota carrageenan-containing surimi also increased after 7 days of storage. Compared to surimi without added carrageenan, the heated Iota carrageenan-containing surimi had higher hardness, gumminess, chewiness, and lower adhesiveness after storage. The overall preference for surimi decreased, while the hardness increased, when carrageenan was added. Therefore, the addition of the iota carrageenan to stored surimi can significantly enhance its hardness.

Background: Vibrio vulnificus is a serious opportunistic human pathogen that has a worldwide distribution in a variety of marine and estuarine environments. Objectives: For this reason, we investigated the distribution of Vibrio vulnificus in coastal areas of Gyeonggido Province from 2018 to 2022. Also, we analyzed the correlation between V. vulnificus leading to infection and two marine environmental factors (water temperature and salinity). Methods: We collected a total of 266 samples from six coastal area points (i.e., seawater, mudflats). Specimens were isolated using selective plating media and isolated strains were identified by a VITEK 2 system. To find the relevance of the isolation rates of V. vulnificus and number of cases of V. vulnificus infection, we summarized the data on 48 cases of V. vulnificus infection from the open data of the Korea Disease Control and Prevention Agency. Results: Among the 266 samples taken during the investigation period, 47 strains were isolated, and the separation rates of V. vulnificus were 17.7%. The monthly isolation rates of V. vulnificus were ranked in the order of August (53.8%), September (33.3%), June (28.6%), and July (21.1%). There was a positive correlation with the temperature of seawater, but salinity was not significant. The number of cases of V. vulnificus infection reported in Gyeonggi-do Province were 18 (37.5%) in September, 14 (29.2%) in August, and eight (16.7%) in October. The proportion was 83.3%. It was relevant to the isolation rates of V. vulnificus in the marine environmental sources. Conclusions: Our data showed that the number of V. vulnificus infection cases could be affected by changes in the distribution of V. vulnificus due to rise the temperature of seawater in the marine environment.

Purpose: The aim of this study was to evaluate the quality of the trauma care system of our hospital, in which emergency physicians care for major trauma patients in the emergency intensive care unit (ICU) in consultation with intervention radiologists and surgeons. Methods: This was a retrospective observational study conducted in an emergency ICU of a tertiary referral hospital. We enrolled consecutive patients who had been admitted to our emergency ICU with major trauma from March 2007 to September 2010. We collected data with respect to demographic findings, mechanisms of injury, the trauma and injury severity score (TRISS), emergency surgery, angiographic intervention, and 6-month mortality. Then, we compared the observed and predicted survivals of the patients. The Hosmer-Lemeshow test and calibration plots by using 10 groups, one for each decile, of predicted mortality were used to evaluate the fitness of TRISS. P-values of greater than 0.05 represent a fair calibration. Results: Among 116 patients, 12 (10.34%) were dead within 6 months after admission to the ICU, and 29 (25.00%) and 38 (32.80%) patients received emergency surgery and angiographic intervention, respectively. The mean injury severity score and revised trauma score were $36.97{\pm}17.73$ and $7.84{\pm}6.75$, respectively. The observed survival and the predicted survival of the TRISS were 89.66% (95% confidence interval [CI]: 84.03~95.28%) and 69.85% (95% CI: 63.80~75.91%), respectively. The calibration plots showed that the observed survival of our patients was consistently higher than the predicted survival of the TRISS ($p$ <0.001). Conclusion: The observed survival for the trauma care system of our hospital, in which emergency physicians care for major trauma patients in the emergency ICU in consultation with intervention radiologists and surgeons, was higher than the predicted survival of the TRISS.

Background: Repeated arousals during sleep have been known to be associated with excessive daytime sleepiness and cardiovascular complications. We investigated the relationship between arousal indices and clinical parameters. Methods: We retrospectively reviewed medical records of 41 patients who performed polysomnography for a diagnosis of obstructive sleep apnea syndrome. We defined total arousal index (TAI) as the number of arousals per hour and respiratory arousal index (RAI) as the number of arousals associated with apnea or hypopnea per hour. Results: There were significant positive correlations between arousal indices and apnea-hypopnea index (AHI) (RAI vs. AHI, r=0.958, p<0.001; TAI vs. AHI, r=0.840, p<0.001). RAI and mean oxygen saturation showed a significant negative correlation with each other (r=-0.460, p=0.002). TAI revealed a significant positive correlation with mean systolic blood pressure (MSBP) and mean diastolic blood pressure (MDBP) (TAI vs. MSBP, r=0.389, p=0.014; TAI vs. MDBP, r=0.373, p=0.019). There was no significant correlation between arousal indices and parameters of sleepiness. RAI had a significant positive correlation with body mass index (BMI) and neck circumference (NC) (RAI vs. BMI, r=0.371, p=0.017; RAI vs. NC, r=0.444, p=0.004). When partial correlation analysis was performed to adjust for other variables, there was significant correlation between RAI and AHI (r=0.935, p<0.001). Conclusion: This study shows that respiratory arousal index could be a useful index reflecting of severity of obstructive sleep apnea syndrome. Arousal during sleep would be concerned in the development of cardiovascular complication of obstructive sleep apnea. And some anthropometric factors would contribute to the development of arousals during sleep. Further studies are needed to clarify any cause-effect relationship.

연구배경: LKB1 (STK11)유전자는 Peutz-Jeghers syndrome에서 생식세포 돌연변이가 있으면 소화기와 폐를 포함한 타 장기의 암 발생 위험도가 증가한다고 알려져 있으며, 또한 종양 억제 기능이 있다고도 알려지고 있다. 하지만 현재까지 폐암에서 LKB1 유전자의 생물학적 기능이 명확하게 밝혀져 있지 않아, 저자들은 폐암조직에서 LKB1 단백질 발현소실과 임상양상 및 조직병리와의 연관관계를 알아보고자 하였다. 방법: 1998년 3월부터 2006년 3월까지 본원에 내원하여 원발성 폐암으로 진단받고 근치적 절제술을 시행 받은 77명의 환자를 대상으로 하였다. 파라핀에 포매된 조직을 택하여 면역조직화학염색법으로 LKB1 단백질 발현을 확인하였고, 정상 기관지 상피세포 세포질에서의 단백질 발현과 비슷한 정도의 발색을 갖는 종양세포가 전체 종양에서 30% 이상인 경우를 양성으로 판정하였다. 결과: LKB1 발현 양성은 40% (31/77)였고, 남성, 흡연, 편평상피암인 경우에 LKB1 발현 음성률이 통계적으로 유의하게 높았다. 종양위치가 중앙부위일수록 LKB1 발현 음성률이 증가하는 경향이 있으며, 종양 위치가 말초 부위인 경우 흡연력이 있는 군에서 LKB1 발현 음성률이 통계적으로 유의하게 높았다. TNM 병기가 진행할수록 LKB1 발현 음성률이 증가하는 경향이 있었으며, T2 병기 이상, N 병기가 진행할수록 LKB1 발현 음성률이 높아지는 경향이 있었으나, 통계적 유의성은 보이지 않았다. 결론: 원발성 폐암환자에서 LKB1 발현소실은 성별, 흡연력, 조직병리 형태와 의미있는 상관관계를 보였으나, 예후인자로서의 의의는 찾지 못했다. 하지만 환자의 숫자가 적어 추후의 연구가 이루어져야 할 것으로 사료된다.

Pbjective : A significant proportion of children with autism spectrum disorders (ASD) have regression characterized by loss of previously acquired skills. The purpose of this study was to compare demographic, clinical characteristics and autism-related symptomatology of the children who have regression with children who don't have regression. Methods : The subjects with ASD and their unaffected siblings (SIB) were recruited from the Korean Autism Genetic Study Consortium. Typically developing children (TC) were volunteered from community. The subjects were administered the Korean version of Autism Diagnostic Interview-Revised (K-ADI-R) and the Korean version of Autism Diagnostic Observation Schedule (K-ADOS) to diagnose or exclude ASD. Regression was defined on the basis of K-ADI-R data. The Korean version of Vineland Adaptive Behavior Scale (K-VABS), Aberrant Behavior Checklist (K-ABC) and Social Responsiveness Scale (K-SRS) were obtained from their parents. Results : Regression occurred in 8.33% (n=14) of children with ASD (n=168). Any SIB (n=166) and TC (n=53) did not experience regression. Regression was associated with lower IQ and lower score of K-VABS. There was no difference in autism symptom severity and K-ABC, K-SRS scores, between children with ASD who experienced regression and who did not. Conclusion : Regression seems to be a distinctive feature of ASD. Regression is associated with cognitive and more general functions, rather than symptoms specific to autism.
