Objectives : The objective of this study is to assess the prevalence and risk factors of metabolic syndrome (MS) among inpatients with schizophrenia, and to compare with general population. Methods : Nine hundreds seventy inpatients were included to assess the prevalence of MS from two mental hospitals in Yong-in city. Assessment of MS was performed based on modified American Heart Association criteria with abdominal obesity threshold of 90cm for men, 85cm for women. Comparative analysis was performed using age- and gender matched sample from Korea Health and Nutritional Examination Survey III. For evaluating risk factors, analysis included 766 inpatients taking consistent medications at least for 30 days. Results : The prevalence of MS of inpatients with schizophrenia was 26.2%, in females it was 33.2%, compared to 20.2% in males(p < 0.001). Compared to general population, the prevalence of MS was significantly lower in male and higher in female patients. In terms of criteria prevalence, who met abdominal circumference criterion were more prevalent in patient group(p < 0.001). After multivariate analysis, female gender and old age remained as risk factors of MS. Conclusions : The prevalence of MS of inpatients with schizophrenia was 26.2% and significantly low compared to general population. Female gender and old age were risk factors of MS.

A cross-sectional survey was used to investigate the rates of overweight and obesity (BMI$\geq$25), and eating attitudes among college students. Data were collected at a large southeastern university. Adolescents (ages 18-25) self-reported weight and height (to calculate BMI), and, in addition to demographic information, completed the eating attitudes (EAT 26) scale to assess dieting tendencies. Significance of the mean BMI differences between gender and ethnic background were assessed by one-way analysis of variance (one-way ANOVA). Chi-square was used to determine whether the rate of those with BMI$\geq$25 between gender and ethnic background was statistically significant. While 52.7% of the students' BMI were within the normal weight category, 15.2% were underweight, 21.3% were overweight, and 10.8% were obese. The rate of BMI$\geq$25 differed by gender and ethnicity, with males and African Americans having higher rates. About 12 % of the participants reported disturbed eating behavior, which is lower than previously reported. Even so, results support the generally held belief that disturbed eating attitudes and unhealthy dieting are common among college students, especially among females. At the same time, disturbed eating attitudes are not just the domain of young female students; about 10% of college males reported disturbed eating attitudes. Findings of this study call for obesity prevention/intervention and lifestyle modification outreach programs among college students. Weight status and unhealthy eating behaviors of college. students should be a concern to health care professionals. While obese young adults will likely remain obese throughout their adult life, excessive dieting among students, which is linked to eating disorders and other health hazards, does not provide healthy and adequate alternatives for maintaining a normal BMI. Implications for obesity prevention programs are discussed.

Purpose: Vitamin D deficiency may cause bone loss and increased inflammation, which are well-known symptoms of periodontal disease. This study investigated whether serum 25-hydroxyvitamin D (25(OH)D) levels are associated with periodontal disease status and tooth loss. Methods: Cross-sectional data from 5,405 individuals aged ≥50 years (2,253 males and 3,152 females) were obtained from the 2008-2010 Dong-gu study, a prospective cohort study of risk factors for chronic diseases. Periodontal examinations were conducted to evaluate the number of remaining teeth, the periodontal probing depth (PPD), the clinical attachment level (CAL), and bleeding on probing. The percentages of sites with PPD ≥4 mm and CAL ≥4 mm were recorded for each participant. The severity of periodontitis was classified using the Centers for Disease Control and Prevention and the American Academy of Periodontology case definitions. Serum 25(OH)D levels were classified as reflecting severe deficiency, deficiency, insufficiency, or sufficiency. Multivariate linear regression analysis was performed to assess the associations of serum 25(OH)D levels with periodontal parameters and the number of remaining teeth after adjusting for confounders including age, smoking status, alcohol consumption status, month of blood collection, and physical activity. Multivariate logistic regression was used to evaluate the association between serum vitamin D levels and severe periodontitis. An overall statistical analysis and a stratified analysis by sex were performed. Results: Overall, the rates of severe deficiency, deficiency, insufficiency, and sufficiency were 6.5%, 67.9%, 22.4%, and 3.2%, respectively. After adjustment for confounders, vitamin D levels were directly associated with the number of remaining teeth, an association that was significant in males, but not in females. Sufficient serum 25(OH)D was associated with a low frequency of severe periodontitis. Conclusions: This population-based cross-sectional study indicates that low serum 25(OH) D is significantly associated with tooth loss and severe periodontitis in Koreans aged 50 years and older.

연구배경 : 우리나라 국민을 대상으로 실시한 폐활량검사의 판정과 해석은 우리나라 국민을 대상으로 구한 폐활량 예측식이 사용되어야 한다. 그 동안 외국인을 대상으로 구한 폐활량 예측치가 사용되어 오류가 있었다. 본 연구에서는 전 국민을 대상으로 대표성 있고 신뢰할 수 있는 노력성 폐활량과 일초간 노력성 폐활량, 6초간 노력성 폐활량, 일초율에 대한 정상 예측식을 개발 하고자 하였다. 연구방법 : 전 국민을 대상으로 층화표본 추출법을 사용하여 조사대상을 선정하였으며, 폐활량검사기와 검사방법, 검사과정, 결과의 선택을 미국흉부학회에서 권고하는 기준에 따라 체계적인 정도관리와 질관리를 실시하였다. 폐활량 검사를 실시한 대상자 4,816명 중에서 비흡연자이면서 폐활량에 영향을 미칠 수 있는 호흡기 질환 및 증상이 없고, 흉부방사선학적 검사에서 심폐 이상 소견이 없으면서, 폐활량에 영향을 미치는 유해인자에의 노출력이 없는 대상자는 1,212명으로 남자 206명, 여자 1,006명이었다. 이들은 지역과 연령별로 우리나라 국민을 대표할 수 있었다. 통계분석에서 혼합효과모델을 적용하여 AIC 값이 가장 작은 모델로서 남자와 여자에 공통적으로 포함된 변수들을 일반선형회귀분석에 적용하여 폐활량 예측식을 구하였다. 결 과 : 노력성 폐활량의 예측식은 남자 -4.8434 - 0.00008633*연령$^2$(년) + 0.05292*신장(cm) + 0.01095*체중(kg)이었으며, 여자 -3.0006 - 0.0001273 *연령$^2$(년) + 0.03951*신장(cm) + 0.006892*체중(kg)이었다. 일초간 노력성 폐활량의 예측식은 남자 -3.4132 -0.0002484*연령$^2$(년) + 0.04578*신장(cm)이었으며, 여자 -2.4114 - 0.0001920*연령$^2$(년) + 0.03558*신장(cm)이었다. 6초간 노력성 폐활량의 예측식은 남자 -4.4244 -0.0001367*연령$^2$(년) + 0.05156*신장(cm) + 0.008246*체중(kg)이었으며, 여자 -3.1433 - 0.0001442*연령$^2$(년) + 0.04018*신장(cm) + 0.007077*체중(kg)이었다. 일초율의 예측식은 남자 119.9004 - 0.3902*연령(년) - 0.1268*신장(cm)이었으며, 여자 97.8567 - 0.2800*연령(년) - 0.01564*신장(cm)이었다. 결 론 : 본 예측식은 미국흉부학회에서 제시하고 있는 연령과 신장 변수에 체중이 포함되어 차이가 있었다. 이러한 이유는 연령효과와 젊은 연령에서 신장과 체중이 급격하게 변화하는 체격효과가 복합적으로 작용하기 때문이라고 해석된다. 본 예측식과 다른 국내 및 국외 예측식을 비교할 때 본 예측식이 노력성 폐활량과 일초간 노력성 폐활량, 일초율의 예측치를 높게 추정하였으나 대부분 그 차이가 10% 이내로 비슷하였다. 코카시안인 백인을 대상으로 구한 외국의 예측식보다 본 연구의 정상 예측치가 낮지 않았다. 이러한 이유로는 우리나라 젊은 사람들의 체격조건의 변화와 함께 엄격한 정상인의 선정기준, 검사방법과 검사결과의 정도관리 및 질관리에 기인하는 것으로 판단되었다.

Objectives: Many conditions of the oral and maxillofacial region require hospitalization and in-patient care. The average length of stay (LOS) of these patients varies and is usually affected by multiple confounding variables. However, even with an increasing number of hospital admissions, published evidence on the factors that affect the LOS of oral and maxillofacial patients is lacking. Therefore, this study assessed the LOS of in-patients at the oral and maxillofacial surgery department of a government-funded, multi-specialty hospital in Malaysia, based on their reasons for admission and other factors. Materials and Methods: Our samples were collected retrospectively over a 5-year period and included patients with maxillofacial infections, post-trauma stabilization, facial bone fracture surgery, benign and malignant lesion surgery, dentoalveolar surgery, and other maxillofacial surgeries as reasons for admission. Factors potentially affecting LOS were also recorded, and their significance was determined using multiple logistic regression analyses. A P-value of less than 0.05 was considered to be statistically significant. Results: A total of 1,380 patients were included in this study. Most (84.5%) of our in-patients were of Malay ethnicity, and males outnumbered females in our sample by 502 subjects. The median LOS of our in-patients was 3 days. Sex, ethnicity, age, reason for admission, and American Society of Anesthesiology (ASA) classification were factors that significantly affected LOS. Conclusion: The median LOS reported in this study was 3 days. LOS was significantly affected by sex, ethnicity, age, reason of admission and ASA classification.

Background: Workers are exposed to several risks in academic laboratories due to the presence of potentially hazardous substances. The main objective of this study was to assess the prevalence of accident occurrence and associated risk factors among laboratory workers at the scientific laboratories of the public university in Lebanon and the impact of safety measures training and availability. Methods: In this observational study, a survey was conducted for one year in scientific laboratories at faculties of the public university. Results: Among the participants (N = 220), 45.0% have had accidents; the main cause was exposure to chemicals (73.7%) and more specifically by inhalation (45.4%). Females (85.9%) were more exposed to accidents than males. Laboratory workers with a master's degree, a full-time schedule, and more than ten years of experience were significantly more exposed to accidents (p < 0.05). A significant association was found between accident occurrence and training on management of hazardous products (p = 0.044), risks related to workplace (p = 0.030), eyewash and emergency shower (p < 0.001), first aid (p = 0.012), and facial protection availability (p = 0.019). In spite of the lack of safety culture and efficient training on laboratory safety, participants have shown a very good perception regarding safety measures to be applied in case of work accidents. Conclusion: Based on our findings, the prevalence of accident occurrence is elevated among lab workers at the public university. The impact of regular training on laboratory safety preventive measures is of great importance to ensure the efficiency of occupational health and safety in scientific laboratories.

Introduction: Bisphosphonates is used widely for the treatment of the Paget's disease, multiple myeloma, bone metastases of malignant tumors with the prevention of pain and their pathological fracture. However, it was recently suggested that bisphosphonates related osteonecrosis of the jaw (BRONJ) is a side effect of bisphosphonate use. Materials and Methods: Twenty-four individuals, who were referred to the Department of Oral and Maxillofacial surgery, Dankook University Dental Hospital, were selected from those who had exposed bone associated with bisphosphonates from January, 2005 to December, 2009 according to the criteria of American Association of Oral and Maxillofacial Surgeons (AAOMS) for BRONJ. The patients group consisted of 7 males and 17 females between the age of 46 to 78 years (average 61.8 years). Each patient had panoramic imaging, computed tomography (CT), whole body bone scanning performed for a diagnosis and biopsy sampling from the necrotizing tissue. C-terminal cross-linking telopeptide of type I collagen (CTX) level of patients who had undergone surgical intervention was measured 7 days before surgery. Results: The main cause of bone exposure was post-extraction (15), chronic periodontitis (4), persistent irritation of the denture (3). Twenty people had undergone BRONJ treatment for two to eight months except for 4 people who had to maintain the bisphosphonates treatment to prevent a metastasis and bone trabecular pain with medical treatment. When the bisphosphonate treatment was suspended at least for 3 months and followed up according to the AAOMS protocols, the exposed necrotizing bones were found to be covered by soft tissue. Conclusion: Prevention therapy, interruption of bisphophonates for at least 3 months and cooperation with the physician for conservative treatment are the essential for treating BRONJ patient with high risk factors. The CTX level of BRONJ patients should be checked before undergoing surgical intervention. Surgical treatments should be delayed in the case of a CTX level <150 pg/mL.

Background Though in facial plastic surgery, the ideal nasal characteristics are defined by average European-American facial features known as neoclassical cannons, many ethnicities do not perceive these characteristics as suitable. Methods To investigate the preferences for nasofrontal angle, nasolabial angle, dorsal height, alar width, and nasal tip projection, manipulated pictures of one male and one female model were shown to 203 volunteer patients from a tertiary university hospital's facial plastic clinic. Results The most aesthetically preferred nasofrontal angles were 137.64 ± 4.20 degrees for males and 133.55 ± 4.53 degrees for females. Acute nasofrontal angles were more desirable in participants aged 25 to 44. The most preferred nasolabial angles were 107.56 ± 5.20 degrees and 98.92 ± 4.88 degrees, respectively. Volunteers aged 19 to 24 preferred more acute male nasolabial angles. A straight dorsum was the most desirable in both genders (0.03 ± 0.78 and 0.26 ± 0.75 mm, respectively). The ideal male and female alar widths were -0.51 ± 2.26 and -1.09 ± 2.18 mm, respectively. More 45- to 64-year-old volunteers preferred alar widths equal to intercanthal distance. The ideal female and male tip projections were 0.57 ± 0.01 and 0.56 ± 0.01, respectively. Conclusion Results indicate that the general Iranian patients prefer thinner female noses with wider nasofrontal angles for both genders. However, the ideal nasolabial angles, dorsal heights, and tip projections were consistent with the neoclassical cannons. Besides ethnic differences, the trend of nasal beauty is also affected by gender, age, and prior history of aesthetic surgery.

Background: Tobacco use is a leading cause of preventable morbidity and mortality from non-communicable diseases. The objectives of the study were to determine the percentage of annual income used to purchase tobacco-related products and treat tobacco-related illnesses, and assess the characteristics of smokers and their awareness of the health-related risks of smoking. Method: Stratified and snowball sampling methods were used to obtain information (via a 17-item, close-ended questionnaire) from 85 adult respondents (49 males and 36 females). The instrument comprised of demographic characteristics, smoking behavioural/lifestyle, health, and micro socio-economics. Results: There were no significant differences between individuals who were affected by chronic obstructive pulmonary disorder (COPD) (14.1%) and cardiovascular disease (18.8%). It was found that respondents spend 30-39% of their annual income on tobacco-related products. Forty percent (40.0%) and 41.7% of respondents with lung cancer and COPD respectively spend more than 50% of their annual income to treat these diseases. The majority (80%) of those who continues to consume tobacco-related products were uncertain as to why they were doing it. Not all the smokers were aware of the dangers of tobacco consumption despite their level of education. Conclusion: The majority of the respondents who had tobacco-related illnesses such as lung cancer and COPD spend a significant amount of their income on their health care. Not all the smokers were aware of the dangers of tobacco consumption despite their level of education. This suggests the need for increase public awareness where both smokers and non smokers are being fully or adequately informed about the dangers or health risks of tobacco consumption.
