There are increasing number of patients having dental treatment under outpatient general anesthesia. There were researches that studied patients treated under outpatient general anesthesia in Chonbuk National University Dental hospital between 2005~2013. However, there has been an absence of research since 2013. Therefore, the aim of this research is to study cases regarding outpatient general anesthesia visiting Chonbuk National University hospital between 2014~2017 and analyze the trends of these patients. The medical records of 409 cases from January, 2014 to December, 2017 were reviewed. From the patients' charts, data on sex, residence, visiting dates, disability status, and types and number of treatments was collected and investigated. The number of cases has increased from 86 in 2014 to 140 in 2017. Among 409 cases, 275 cases(67.2%) had disabilities, with mental disabilities consisting most of the disabilities. 192 cases were aged under 20 years old mostly with no disabilities, 142 cases were 20~39 years old mostly with mental disabilities, and 75 cases were 40 years old or more mostly with physical disabilities. The conservative treatment was performed most frequently in both disabled and non-disabled patient groups. There was an increasing trend in the number of patients treated under outpatient general anesthesia, and more than half were disabled patients. In order to meet this demand, Chonbuk National University Dental Hospital increased the number of general anesthesia pracrice. To follow this trends, the implementation of safe outpatient general anesthesia system and cooperation among teams is needed to improve the quality of treatments.

Purpose: Recently, the incidence of acute hepatitis A has increased nationwide and is related to a low rate of IgG anti-HAV production. To establish effective measures for preventing hepatitis A virus infection, an epidemiologic study on the seroprevalence of anti-HAV is needed. Thus, we investigated the seroprevalence of IgG anti-HAV in children living in Gwangju and Jeonnam. Methods: IgG anti-HAV levels were measured in a total of 1,435 patients who visited Chosun University Hospital between January 2009 and December 2009. Results: The overall seropositve rate was 40.8% (586/1,435). The seropositive rates were 41% among children under the age of 1 year, 49.9% for children 1~5 years old, 51.1% among individuals 5~10 years old, 12.9% for individuals 10~15 years old, and 8.2% for subjects over 15 years old. There was no significant difference between genders in any group. The seropositive rates in Gwangju and Jeonnam were 57.3% and 32.9% for children under the age of 1 year, 52.5% and 44.3% for children 1~5 years old, 60.2% and 33.9% among children 5~10 years old, 14.1% and 9.7% for children 10~15 years old, and 10.8% and 4.2% for individuals over 15 years old. Conclusion: The results demonstrated the low rates of IgG anti-HAV, particularly among subjects over 10 years old, which suggests the possibility of increasing clinical HAV infection rates among adults in the near future. We should actively prevent the spread of hepatitis A virus. Vaccination is the most effective means of preventing hepatitis A virus transmission among persons at risk for infection. Hepatitis A vaccination is recommended for children who have low IgG anti-HAV seropositive rates.

Backgrounds: According to a high interest in health these days, a bicycle is being highlighted as a means of leisure activity and auxiliary transportation means. Along with an increase in this interest, there is tendency that even the width of bicycle utilization gets diverse and that bicycle accident is also rapidly growing. Purpose: The purpose of this study was to suggest a prevention measure available for reducing occurrence of bicycle accidents by analyzing the Epidemiological characteristics according to age and injury severity in bicycle-injured patients. Methods: This study analyzed 115 materials suitable for this study by examining a medical record of patients, who received the hospitalized treatment owing to bicycle accident from January 1, 2011 to December 31 at one general hospital in S city. Results: The male-and-female ratio of bicycle-injured patients stood at about 7:3. The average age was 38.14(${\pm}21.59$) years old. The largest injury happened in 40-59 years old(31.3%). The averagely hospitalized period was 17.33(${\pm}18.12$) days. Injury severity was the ratio of 2:8 in a mild case versus a serious case. As for drinking and smoking characteristics according to age, the injury occurred the most in between 40 and 59 years old for people with drinking and smoking and in under 19 years for people without drinking and smoking. According to injury severity, the ratio of serious case got higher in the higher age. This was indicated(${\chi}^2$=15.675, p=0.001) to be statistically significant. Conclusion: In this study, a bicycle accident was indicated to have high injury risk in young children, adolescents, and old-age group. Prevention measure and publicity are demanded for reducing injury occurrence such as the prevention education for bicycle accident and wearing protective gear focusing on the ages of corresponding to groups with risk of injury occurrence. In addition, the security of safe movement route is necessarily demanded in order to increase application level as an auxiliary transportation means.

Background: Breast cancer is the most common female cancer in Kerala, South India, with the incidence increasing in the past two decades, also in young women. However, there are limited data regarding the burden of disease, its epidemiology and histopathological characteristics in the state. Materials and Methods: This desciptive study covered 303 breast cancers evaluated during the period of December 2011 to August 2013 in the Department of Pathology, Government Medical College, Kottayam.The patients were also interviewed regarding selected risk factors. Results: The majority of the cases were 41-60 years of age with a mean at presentation of 53 years. Infiltrating ductal carcinoma was the most common subtype, followed by pure mucinous carcinoma and then lobular carcinoma. Of the cases, 6.6% were nullipara and 52.8% had fewer than or equal to 2 children. Median age at first child birth was 23 years (national value-19.8 years). A significant proportion (15%) had family history of breast cancer. Some 13.5%(41 cases) comprised the young breast cancer group (${\leq}40$years) with a mean age at first child birth in them was 27.4 years, 5 being nullipara and 6 having a positive family history. Conclusions: Breast cancer awareness, better availability of screening techniques and identification and targeting high risk groups all help to tackle the increasing load of breast carcinoma. A good proportion of cases comprised the young breast cancer group (under 40). Younger women should thus also be educated about breast carcinoma-risk factors, symptoms and diagnostic techniques to help in early detection and effective approach esto treatment.

This study was performed to develop an index assessing the overall diet quality for Korean. The study subjects consisted of preschool children (PC), elementary school children (EC), high school students (HS), college students (CS), and adults over 30 years old living Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 people. Newly developed Korean diet quality index (KDQI) was an index assessing the overall diet quality from the view point of balance. KDQI was based on the nutritional problems of Koreans, dietary risk factors for chronic degenerative diseases, 5 major food groups, and dietary guidelines. The ten components of KDQI were vegetables, fruits, dairy products, dietary variety score, calcium intake, iron intake, energy intake, fat intake, and cholesterol intake. The full score of each component was 10 points and the score of KDQI was calculated by summing the scores of the 10 components. When the KDQI was applied to this study subjects, the distribution of subjects KDQI scores was similar to normal distribution. Mean score of KDQI was 56.0 and the range of the mean by age was from 45.7 for the subjects over 70 years old to 60.7 for the elementary school children. The components which composed the lowest three means were dairy intake, fruit intake, Ca intake in most age groups. Mean score of DVS was one of the highest three but not for the subjects over 50 years old. After subjects with KDQI score over 70 were classified to higher poop and those with KDQI score under 40, to lower group, nutritional characteristics were compared. Energy contributions of carbohydrate, proteins, and fit, percentages of RDA for major nutrients, and dietary diversity scores were more adequate in the higher poop than in the lower group. The lower poop had more risks for chronic degenerative diseases. According to the results, KDQI was valid index to assess the overall diet quality and it could be used to detect risk group for malnutrition and chronic degenerative diseases.

Motor vehicle crashes are the leading cause (70%) of children injury and fatality. 98% of Children under the age of 9 who came to emergency room with a traffic accident are not seated in CRS. Reduction in mortality when using CRS (NHTSA study), 71% for infants of 1-2 years old, 54% for 3-6 years old and 7-12 years old. It is very important and essential to use CRS for child passenger safety. But in Korean market, the CRS fitment rate is relatively low (20~40%). For European market, at the start of 2013, Euro NCAP started to check how easy it is to install the most common seats. And US market, NHTSA is planning a new consumer information program of CRS fitment for near future. This study examines CRS installation performance of 3 vehicles which are produced by GM Korea and 21 CRS which are based on sales volume in Korean market. Purpose of this study is to identify both vehicle and CRS design that causes bad interaction for CRS installation.

Tonsillectomy and adenoidectomy are the most common operations in the ENT field. Recent emphasis on careful selection of patients for these procedures derives from concern for complications of surgery, as well as the immunologic and anatomic functions of tonsils and adenoids. Adenoidectomy can relieve nasopharyngeal airway obstruction caused by enlarge adenoids, and can prevent complications such as heart failure and recurrent or chronic otitis media. We researched 117 cases of tonsilloadenoidectomy patients and 266 patients having routine examination from March, 1979 to February, 1981, and described the A/N ratio derived from linear measurements of lateral radiographs of the nasopharynx. The results of Impedance Audiometry and X-ray films from 117 cases of T&A patients were compared: 1) The average A/N ratio by age groups for 266 cases of normal children showed: 0.508 for age group, 0 to 3 years old, 0.533 for age group, 4 to 6 years old, 0.524 for age group, 7 to 9 years old, 0.519 for age group, 10 to 12 years old, 0.507 for age group, 13 to 15 years old, 0.481 for age group over 15 years old. The peak value lies in the age group of 4 to 6 years old. The sex difference of A/N ratio was not significant. 2) The average A/N ratio by age groups from 117 cases of T&A patients showed: 0.709 for age group, 0 to 3 years old, 0.733 for age group, 4 to 6 years old, 0.693 for age group, 7 to 9 years old, 0.707 for age group, 10 to 12 years old, 0.620 for age group, 13 to 15 years old, 0.756 for age group over 15 years old. 3) Among the 117 cases of T&A patients, the average A/N ratio for 57 cases in normal tympanogram was 0.688 and the average A/N ratio for 60 cases in abnormal tympanogram was 0.705. 4) Among 57 cases in abnormal tympanogram: 6 cases (10.5%) showed 0.40-0.59 of A/N ratio, 44 cases (77.2%) showed 0.60-0.79 of A/N ratio, and 7 cases (12.3%) showed 0.80-0.99 of A/N ratio. 5) Among 117 cases of T&A patients, 3 of 15 cases showing A/N ratio under 0.6, and 67 of 102 cases showing A/N ratio over 0.6, had paranasal sinusitis.

Thirty-three patients less than 40 years of age were diagnosed at CS Dept. of Catholic University Medical College between 1979 and 1988 as having primary lung cancer. There were 22 men and 11 women; the average age was 36.3 years. The youngest patients was 23 years old. Eighteen male patients were only habitual smokers more than 1 pack per day. In the 33 cases, the distribution by tumor type was as follows: squamous cell carcinoma 36.4%[13 cases]; adenocarcinoma 33.3%[11 cases]; small cell carcinoma 24.2%[8 cases]; and large cell carcinoma 3.0%[1 case]. At the time of diagnosis, 2 patients[6.1%] had stage I disease, 2[6.1%] had stage II disease, 5[15.6%] had stage IIIA disease, 10[30.3%] had stage lllB disease, and 14[42.4%] had stage IV disease. Thirteen patients[36.4%] underwent an exploratory thoracotomy. Of these patients, 9[27.3%] had surgical resection[six lobectomies, two pneumonectomies, and one wedge resection]. Thirty-one patients were treated with palliative radiation therapy, chemotherapy, or combinations of each. The survival rate at 1 year, 3 year, and 5 year were 48.2%, 14.5%, and 8.3% respectively. But in the resectable 9 patients, they were 78.1%, 43.6%, and 33.3% respectively.

Foreign body (FB) impaction in the maxillofacial area could be caused by knives, glass fragments, and vegetative materials. We present the rare case of a 62-year-old man with a large glass FB in the left cheek retained for over 40 years. He had traffic accident over 40 years ago and glass fragments impacted on his left cheek. Glass fragments were retained around the zygomatic arch with dimpled scar and unclear serous discharge, but other facial motor or sensory dysfunction was not observed. We confirmed three glass fragments with radiologic examination including plain radiograph and computed tomographic image. Under general anesthesia, impacted glass fragments were removed through the direct incision on the dimpled scar and the additional incision on the left lateral canthal area. Remnant FBs were not seen on an intraoperative C-arm radiograph. After 2 days of irrigation for inflammation control, the dimpled wound was sutured. The wound was healed without major complication and the original dimpled scar was much improved.
