ABSTRACT

OBJECTIVE: The shock index (SI), as a trauma triage tool, is a capable clinical indicator of hemodynamic instability and hypovolemic shock, but the conception of SI is contradictory to shock. The reverse shock index (RSI) was introduced recently, but its utility has not been sufficiently proven. METHODS: This study examined the RSI utility by evaluating the procedures performed at an emergency department (ED) and the associated outcomes when the RSI is used alone or in combination with the Korean Triage and Acuity Scale (KTAS). This was a retrospective study conducted by including data of 4,789 adult trauma patients for a year. The clinical variables, procedures performed on patients, and outcomes were investigated. The median RSI was 0.9 in the RSI < 1 group. RESULTS: Patients in the RSI < 1 group had a higher odds of requiring procedures at the ED and for experiencing worse outcomes: intubation (odds ratio [OR], 5.4; 95% confidence interval [CI], 2.3–13.1; P < 0.001), chest tube insertion (OR, 6.5; 95% CI, 0.4–111.84; P < 0.001), use of emergency drugs (OR, 3.6; 95% CI, 1.5–8.5; P < 0.001), circulatory support (OR, 5.4; 95% CI, 2.3–12.9; P < 0.001), intensive care unit admission (OR, 3.5; 95% CI, 1.8–6.8; P < 0.001), and mortality during the ED stay (OR, 20.4; 95% CI, 5.5–75.7; P < 0.001). In the group with KTAS 1–3, trends similar to those in the RSI < 1 group were observed. Patients with RSI < 1 had more severe injuries and poorer outcomes than those with RSI≥1, regardless of whether the RSI was used alone or in combination with KTAS. CONCLUSION: RSI can provide an appropriate triage with concurrent KTAS use.

ABSTRACT

OBJECTIVES: In this study, we strived to determine the possibility of socioeconomic welfare in oral healthcare by analyzing the National Health Insurance (NHI) coverage rate. To date, efforts to realize the “social economy” of healthcare are active. While oral disease is common and chronic among Koreans, the rate of NHI coverage of dental clinics is substantially lower than that of the medical clinics. METHODS: We defined the NHI coverage of dental clinics as a proxy for “social skills” to improve oral health problems. The data were collected through a comparative analysis of the NHI coverage of dental clinics and that of non-dental clinics, in health welfare social cooperatives. RESULTS: The NHI coverage rate of the dental clinics in health welfare social cooperatives ranged from 0.97 to 2.62 times that of the non-dental clinics in health welfare social cooperatives. CONCLUSIONS: In conclusion, responsible management is recommended for making health welfare social cooperatives meaningful as a social economy.

ABSTRACT

OBJECTIVES: To evaluate the effectiveness of sodium bicarbonate dentifrices in reducing gingivitis and tooth abrasiveness and improving tooth gloss, as compared to a conventional fluoride/silica-containing dentifrice. METHODS: In this double-blinded, randomized clinical study with a paralleled design, 73 healthy adult volunteers (age, 18-39 years), with more than 20 teeth were selected and randomly allocated to the following groups: a control group, a 35% baking soda group, and a 65% baking soda group. Professional plaque controls were provided to all subjects and the same control dentifrice was used for 14 days. At baseline, all subjects received an assigned dentifrice and were instructed to brush three times daily. The tooth gloss and gingival bleeding index were measured at baseline, 45, and 90 days. For measuring surface roughness, toothbrushes were replaced with electronic tooth-brushing machines, and the bovine specimen was brushed via 10,000 horizontal shuttle movements. The surface roughness was measured by a confocal laser scanning microscope (CLSM; Carl Zeiss, LSM-5 Pascal, Germany) Each variable was analyzed by the paired t-test, and change in each variable among groups was analyzed by analysis of variance (ANOVA). Reliability of the gloss was analyzed by an intra-class correlation coefficient. RESULTS: Compared to the controls, the 65% sodium bicarbonate dentifrice group showed significant improvement with regard to the tooth gloss for 90 days as well as a significant inhibitory effect on gingivitis; the 35% sodium bicarbonate dentifrice group, however, showed no inhibitory effect on gingivitis. The relative roughness of the tooth surface in the dentifrices of both the sodium bicarbonate dentifrice groups was significantly low. Further, there was no significant difference with the distilled water group. CONCLUSIONS: The sodium bicarbonate dentifrice has an inhibitory effect on gingivitis. Further, this dentifrice showed low abrasiveness and a glossing effect on teeth.

ABSTRACT

OBJECTIVES: The aim of this study was to estimate the economic costs and benefits of a water fluoridation program in the city of Jinju, Korea. METHODS: In 2009, dental surveys were conducted on 2,315 children aged 6-12 years in Jinju, which had been fluoridated for 11 years. The decayed/missing/filled teeth (DMFT) scores of children in Jinju were compared to the DMFT scores of same-aged children in non-fluoridated small- and medium-sized cities in the fourth Korean National Health and Nutrition Examination Survey conducted from 2007 to 2009 by the Korea Centers for Disease Control and Prevention. The reduced number of decayed permanent teeth by the water fluoridation program was estimated as the difference between the DMFT scores of children in Jinju and those in non-fluoridated small- and medium-sized cities. The economic benefits were estimated by the savings from reduced dental treatment costs by using the reduced number of decayed permanent teeth from the water fluoridation program. All annual costs and benefits were calculated from 1998 to 2009. The social rate and untreated rate of decayed teeth were applied as 3% and 20%, respectively. The annual benefit-cost ratio was estimated by using the annual benefits and cumulative program costs. RESULTS: The economic benefit in 2009 from a water fluoridation program was estimated as 57,496,000,000 Korean Won (KRW), and the cumulative cost in 2009 was estimated as 1,387,000,000 KRW. The net present value in 2009 from a water fluoridation program was 56,109,000,000 KRW. The benefit-cost ratio in 2009 was estimated as 41.4. CONCLUSIONS: The economic benefit of a water fluoridation program in Jinju city was evaluated as excellent.

ABSTRACT

We report a case of acute upper limb ischemia suspected to have originated from methicillin-resistant Staphylococcus epidermidis native valve endocarditis in a 57-year-old man who had complained of sudden-onset fever and pain in the right hand. 3D computed tomography of the right upper extremity detected a thrombus occluding the brachial artery. Echocardiography showed a large vegetation on the aortic valve. Thus, we suspected, clinically, brachial artery occlusion by septic emboli originating from a large vegetation of the aortic valve. The patient was treated with intravenous antibiotics for the suspected methicillin-resistant Staphylococcus epidermidis-native valve endocarditis with a combination of percutaneous aspiration thromboembolectomy and selective intra-arterial thrombolysis for acute thromboembolic occlusion in the right upper limb. The large vegetation of the aortic valve resolved without surgery and aortic regurgitation improved. The patient recovered uneventfully with no complications, including septic embolism, over the following 11 months.

ABSTRACT

Dental sealants and composite filling materials containing bisphenol-A (BPA) derivatives are increasingly used in children. The aim of this study was to evaluate the association between salivary BPA and the number of tooth surfaces filled with dental sealant, and to determine a cutoff BPA level. Salivary BPA concentration and the number of tooth surfaces filled with dental sealant/resin were determined in 124 age and gender matched children: 62 controls had no dental sealant/resin on their tooth surfaces and 62 cases had more than 4 tooth surfaces with dental sealant/resin. Analysis of covariance (ANCOVA) and conditional logistic regression were performed after controlling for age, gender, salivary flow rate, salivary buffer capacity, frequency of snacking, and frequency of tooth brushing. Salivary BPA levels were 0.002 to 8.305 microg/L. The BPA level of control (0.40 microg/L) was significantly lower than that of case (0.92 microg/L) after controlling for confounders (P = 0.026). Although the 90th BPA percentile had an adjusted OR of 4.58 (95% CI 1.04-20.26, P = 0.045), the significance disappeared in the conditional logistic model. There may be a relationship between salivary BPA level and dental sealant/resin.

ABSTRACT

OBJECTIVES: The aim of the study was to analyze the factors that are related to the illegal dental treatment experience (IDTX), among the Korean adults. METHODS: The raw data for the analysis of IDTX, among the Korean adults, which were aged 17 years and over, were obtained from the dataset of the Korean National Oral Health Survey (KNOHS), which was conducted in 2006. Stratified weighted total 11,808 samples were selected by region and clustered sampling methods. The data of weighted total 11,808 samples were analyzed, using a chi-square test and a logistic regression analysis, by demographic socioeconomic variables of age, gender, area, educational level, occupation, national health insurance, and monthly income. RESULTS: IDTX rate was under 10%, among the adults aged 35~44 years or below the age group. However, it increased to 18.9%, among the adults aged 45~54 years and overtook over 30% among the adults 55 years and over. The age group of high IDTX rate was coincided to the age group of high number of lost teeth. Most of IDTX were presumed to prosthetic treatments. In IDTX rate of samples, aged 45 years and over, odds ratio of females' was 1.3, compared to that of the males'; odds ratio of metropolitan area, 1.2 compared to rural area. IDTX rate was higher among the middle school or below educational level group compared to that of college or over educational level group. IDTX rate of medicaid or not joined to national health insurance group was 31.3%, higher than that of national health insurance group. IDTX rates of low monthly income group, less than 4 million KRW were higher than monthly income group of 4 million KRW or more. CONCLUSIONS: To supply the prosthetic treatments for the population of medicaid and national health insurance is needed to remove illegal dental treatments in Korea.

ABSTRACT

OBJECTIVES: The purpose of this study is to evaluate the oral health status among some disabled persons in Jinju. METHODS: Two dentists taken calibration training from the national oral health survey examined the oral health status on 200 disabled persons in Jinju, in June 2008. The surveyed disabled persons aged 6 to 29 years have been supplied with oral health care services by dentists and oral hygienists of dental clinics established at their schools supported from Jinju Public Health Center since 2006. The data obtained from this survey were analyzed with SPSS statistical package and were compared with the data from other oral health reports on disabled persons examined in 2010 Korean Oral Health Survey by Ministry of Health and Social Welfare. RESULTS: Among the disabled persons in Jinju, DMF rate was 65.00%; DMFT index, 3.10; DT rate, 39.61%; MT rate, 8.94%; and FT rate, 51.45%. DMFT indexes and DT rates of the disabled persons in Jinju were evaluated to be higher than those of the disabled persons from 2010 Korean National Oral Health Survey. CONCLUSIONS: Oral health programs should be strengthened for the prevention and treatments of dental caries for disabled persons.

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate the caries preventive effects of oral health programs composed of pit and fissure sealant and community water fluoridation in Hapcheon-Up, Hapcheon-Gun, the Republic of Korea. METHODS: Dental surveys were conducted on 6 to 14 year old children at Hapcheon-Up, Hapcheon-Gun in 2000 and 2009, respectively. The number of the subjects was 1,957 and 1,535 children in 2000 and 2009, respectively. The percentage of samples among total population aged 6 to 14 years in 2000 and 2009 was 90.6% and 92.3%, respectively. The obtained data from these surveys were analyzed with the PASW statistical package version 18.0 (SPSS Inc., Chicago, IL, USA). The 2009 dental health data including the prevalence of dental caries and fissure sealants on children's permanent teeth was compared to the 2000 dental health data, and assessed using chi-square test and independent-sample t-test. RESULTS: DMF rate of 12-year olds was 76.9% in 2000, and it significantly decreased to 42.5% in 2009. DMFT index of 12-year olds was 3.03 in 2000, and it significantly decreased to 1.07 in 2009. The prevalence rate of sealed permanent teeth among the 12-year olds was 15.4% in 2000, and it significantly increased to 97.2% in 2009. The caries reduction rate from pit and fissure sealant added by community water fluoridation program was calculated as 44.7% in 12-year olds by the difference of DMFT index between 2000 and 2009 year. Logistic regression analysis revealed that both programs were associated with an increasing likelihood of experiencing no dental caries (OR=4.00, 95% CI; 3.23-4.95). CONCLUSIONS: These results suggest that the oral health program composed of pit and fissure sealant and community water fluoridation in Hapcheon was very effective in caries prevention. The program should be expanded to other area to prevent dental caries among children.

ABSTRACT

OBJECTIVES: The aim of this study was to analyze the related factors to dental caries incidence and increments of DMFT index in children's permanent teeth. METHODS: The subjects were 249 elementary school children at the baseline survey. At the four-year follow-up survey, number of subjects reduced to 141. In the first year, all subjects submitted the responses of questionnaire composed of demographic variables and oral health behaviors. They also received oral examination and tests of salivary excretion rate, salivary buffer capacity, Dentocult(R) SM and Dentocult(R) LB. In the first to fourth follow-up year, they received oral examinations. The relation of oral health-related factors with caries incidence and increments of DMFT and DMFS index was analyzed by chi-square test, ANOVA, logistic regression analysis and generalized linear model analysis using Poisson distribution. RESULTS: At four-year follow-up survey, subjects whose Dentocult(R) SM was 2 or higher compared to subjects whose Dentocult(R) SM was 1 or less and subjects whose Dentocult(R) LB was 2 or higher compared to subjects whose Dentocult(R) LB was 1 or less had higher DMFT index increments. In DMFT index increments, the adjusted odds ratio of subjects whose dfs index of primary molars was 11 and more was 4.30 compared to subjects whose dfs index of primary molars was 0 adjusted for gender, daily frequency of toothbrushing and eating between meal, mother's job, oral health education, salivary excretion, salivary buffer capacity and Dentocult(R) SM test. CONCLUSIONS: It was suggested that the caries incidence and increments of DMFT index in permanent teeth should be highly associated with salivary lactobacillus count and dfs index of primary molars.

ABSTRACT

Malignant fibrous histiocytoma (MFH) is a pleomorphic soft tissue sarcoma. Three cases of MFH were reported in our study. The first case involved in the right infratemporal fossa of a 32-year-old female was presented. MR imaging revealed a 5.0x3.3 cm soft tissue mass of inhomogeneous high signal intensity. The second case was found in the right hard palate of a 66-year-old male. CT demonstrated bone destruction and MR imaging showed a 4x4 cm sized soft tissue mass of heterogeneous high signal intensity. The final case was found in the left masticator space of a 37-year-old male. The CT image showed a large mass with massive bone destruction of the left mandibular ramus, while the MRI displayed a soft tissue mass, 8 cm diameter. Our cases exhibited the general features of MFH. MRI is essential in the imaging of MFH, namely to depict tumor borders and demonstrate relationships with adjacent structures.

ABSTRACT

BACKGROUND AND OBJECTIVES: Contralateral acoustic stimulation (CAS) is known to reduce the amplitude of the transient evoked otoacoustic emission (TEOAE) in human. However, the magnitude of the suppression effect evoked by CAS is too small to overcome the problems associated with fluctuating patient conditions as well as the environmental changes. We used an alternating technique to overcome this problem and compared the efficacy of this technique with the classic technique. The aims of this study are to show reduction of the amplitude of the TEOAE with CAS and to evaluate the efficacy of the alternating technique in measuring TEOAE suppression. MATERIALS AND METHOD: TEOAE suppression was measured in 24 ears of 12 normal hearing subjects. Both the alternating technique and classic technique were used in the same subject and condition. TEOAEs were recorded with an ILO 92 dual cannel OAE analyzer. In the alternating technique, one channel was used to stimulate and record TEOAEs from the test ear while the other channel was used to deliver 40, 50 and 60 dBSPL broadband noise to the contralateral ear. But in the classic technique, one channel was used to stimulate and record TEOAEs from the test ear while the broadband noise was applied to the contralateral ear via audiometer headphone. RESULTS: The overall contralateral noise of 40, 50 and 60 dBSPL reduced the amplitude of the TEOAE but only with 60dBSPL significantly reduced in both techniques. As larger CAS was given, the suppressive effect on the TEOAEs was greater in both techniques. But the significant difference was not found between the alternating technique and the classic technique. A total test time was 6 minutes for the alternating technique and 10 minutes for the classic technique. CONCLUSION: We confirmed the reduction of the amplitude of the TEOAE with CAS using both the techniques. No significant difference was found between the results of the alternating technique and the classal technique. We found that the alternating technique thereby decreasing the chance of fluctuating patient and environmental condition.

ABSTRACT

A given facial type can be considered as a syndrome in which various features are aggregated, so a single parameter is not sufficient to accurately identify a given facial type. This study was designed to identify & characterize the skeletal types that blend under the headline-'Cl III,deepbite'. Cephalograms of thirty-four untreated mixed dentition patients, selected mainly on the basis of clinical impression of CI III with reduced lower face heights were studied. The following conclusion can be drawn. 1. CI III malocclusion with reduced lower face height could be classified into three types. 2. Subtype 1 was identified by the following features : strong ramus, more anteriorly positioned upper molars without alveolar hypoplasia, acutely reduced Mn. plane angle. 3. Subtype 2 was characterized by a short ramus, sharply reduced postrior alveolar height, and normal Mn. plane angle. In general, this type had hypoplasia tendency in the vertical dimension. 4. In subtype 3, the AUFH occupying more percentage than ALFH was a outstanding feature. Ramal height was in normal range, alveolar hypoplasia and slightly reduced Mn. plane angle was observed. 5. The features of the subtypes were reflected in certain indices, which can be regarded as discriminative index. LAFH: if reduced, regardless of subtypes, indicates reduced lower ant. face height consistently. FHR: when this ratio is increased, it indicates subtype 1. FHl: when this ratio is in normal range, it indicates subtype 2. FPI: if reduced greatly, it indicates subtype 3.

ABSTRACT

Administration of a subparalytic dose of a nondepolarizing muscle relaxant prior to intubating dose hastens the onset time of neuromuscular blockade. This study was designed to investigate the influence of a priming dose of vecuronium (0.015 mg/kg) and d-tubocurarine (0.05 mg/kg) on intubating dose of vecuronium (0.085 mg/kg). The authors measured TOF ratio using neuromuscular monitoring. This monitoring was carried out by stimulation of ulnar nerve at a frequency of 2Hz every 20 seconds using Datex relaxograph to measure the compound evoked electrographic response of hypothenar muscle. The patients were randomly divided into two groups as priming dose ; vecuronium and dtubocurarine (DTC) group respectively. Mixture of two different nondepolarizing muscle relaxant may produce synergism, although the reason for this synergism is unknown. It may be the results of the action of the drugs at different sites. In our study, we found the results as follows ;1) The rapid onset was occured with d-tubocurarine(0.05 mg/kg) as priming drug than vecuronium (0.015 mg/kg) 2) The duration was longer when d-tubocurarine was used (P<0.05) The authors conclude that the onset is more rapid and the duration is longer when other species of nondepolarizing muscle relaxant is used than same agent is used as priming drug.
