OBJECTIVES: In children and adolescents, the prevalence of overweight has increased in the last 20 years. little research is available on the prevalence of obesity in children with autism spectrum disorders(ASD). The purpose of our study was to determine the prevalence of overweight among a clinical population of children diagnosed with autism spectrum disorders(ASD). METHODS: Retrospective chart review of children ages 3-18 years seen between 2012 and 2015 at a Konyang University hospital psychiatric clinic. Diagnostic, medical, and demographic information was extracted from the charts. Body mass index(BMI) was calculated from measures of height and weight recorded in the child's chart. The Center for Disease Control's BMI growth reference was used to determine an age and gender-specific BMI z-score for the children. RESULTS: In our study, children with ASD compared to non ASD group had significantly higher BMI percentiles (p=0.032). The prevalence of overweight(BMI≥85th to 95th percentiles) and obesity(BMI≥95th percentiles) was 35% and 19% respectively in children with ASD and without ASD. CONCLUSION: Despite noted limitations, our data suggest that overweight and obesity in children with ASD are more prevalent than without ASD. Longitudinal and further study is needed to examine the factors associated with obesity in this population.

OBJECTIVES: Homocysteine has been associated with cognitive impairment and various psychiatric symptoms. This study was designed to examine the relationship exists between plasma homocysteine concentration and behavioral and psychological symptoms of dementia(BPSD). METHODS: 41 subjects with dementia of Alzheimer's type were included in this study. We carried out history taking, physical examination, and cognitive assessment for the diagnosis of dementia of Alzheimer's type based on DSM-IV. We scored the Mini Mental State Examination(MMSE), Global Deterioration Scale(GDS), Clinical Dementia Rating(CDR), and the Korean Neuropsychiatric Inventory(K-NPI). We also measured levels of homocysteine, folate, and vitamin B12 in the plasma. RESULTS: We found statistically significant positive correlations between homocysteine concentration with NPI total score, and with scores of several sub-domains such as delusion, agitation/aggression, depression/dysphoria, and elation/euphoria. No significant correlation existed between homocysteine levels and scores of MMSE, GDS, and CDR. CONCLUSIONS: This study shows that plasma homocysteine levels are associated with BPSD. Further research is necessary to identify pathophysiologic mechanisms underlying these relationships.

PURPOSE: This study was aimed to identify gender-based health inequality and explore impacting factors on health inequality in one province in Korea. METHODS: This was an explanatory study using the secondary data on Chungnam province from the Fifth Community Health Survey from August 16 to Oct 31, 2012. Variables included in this analysis were education level, poverty, marital status, and residential community for socio-cultural characteristics and subjective health status as an indicator of health inequality. Data were analyzed by chi2-test, t-test, ANOVA, and multiple linear regression. RESULTS: There were gender inequalities and disparities in health, and these inequalities were greater in woman than in man (chi2=161.8, p<.001). The impacting factors were education level, poverty, marital status, and residential community, which was accounted for 22.6% of variances of health inequality. Among these variables, gender showed the largest influence in health inequalities. CONCLUSION: To solve health inequalities, it should be considered gender differences based on social determinants of health. It is necessary to develop long term project based on these results and the social determinants model of World Health Organization.

Emphysematous cholecystitis is an uncommon condition which may mimic acute cholecystitis. But it differs from acute cholecystitis in its relatively greater frequency in men and diabetics and has graver prognosis. The condition is diagnosed by demonstration of air in lumen,wall of gallbladder and/or pericholecystic space using a variety of radiographic techniques: simple abdominal radiography, ultrasonography and CT scanning. One illustrative case is presented herein and the pertinent literature is reviewed.

Pneumoconisosis was the first reported occupational disease in korea and was the most common occupational disease until 1990. Nowadays pneumoconiosis is the second most common occupational disease which accounts for more than at least 40% of all the occupational diseases in Korea. Many studies have been carried out in the prevalence rate, incidence rate, and risk factors assessment of pneumoconiosis. Workers exposed to dust used to take health examination once annually by the Industrial Safety and Health Act(1981). The number of coal workers has steadily decreased due to coal rationalization projects which have been strongly driven by the government since 1988 and the occupational environment has been improving. So, the incidence rate of pneumoconiosis will probably be lower in the future. But a disease control system administed for patient control and compensation, which is not involved in epidemiologic studies may not figure out the prevalence rate, incidence rate, mortality rate and the extent of severity of pneumoconiosis. Several problems and expected solutions are mentioned here as follows: 1. workers exposed to dust and pneumoconiosis patients are under government control, but the retired workers are not. Since we evaluate only visiting retired workers, we don't know exactly the current status and whole scale of the retired workers. If possible, the construction of cohort in all the retired workers is needed. 2. Since most of pneumoconiosis patients retired from the work and had changed their job, it is difficult to figure out the prevalence rate of pneumoconiosis just depending on the annual health exam for those workers at risk. So, systemic control for all pneumoconiosis patients is needed. 3. It is difficult to diagnose the onset of pneumoconiosis. We make a decision the time when the patient is diagnosed with pneumoconiosis on its onset. It is difficult to estimate it, especially in the case of retired workers because we can evaluate only persons with respiratory symptoms. The solution of such a problem is construction of cohort in all of the retired workers. 4. Because the patients who died outside of hospital don't seem to be reported, the mortality rate of pneumoconiosis is underestimated. So, systemic control and follow-up observation for all pneumoconiosis patients is needed. 5. A definite severity classification criteria for pneumoconiosis hasn't been established in Korea. We should try to make one. 6. Since workers who had exposed to dust in various mines at least 1 yr are subject to pneumoconiosis laws, workers easily don't report their full dust exposure history. Therefore we can't obtain the exact lifetime dust exposure from administrative data. We should try to make basic raw data of whole dust exposure in workers. It's concluded that the construction of cohort in workers who are or were exposed to dust in various mines is required and epidemiologic study of pneumoconiosis should be carried out with the administrative control of pneumoconiosis side by side. With the database of these materials, we can speculate and devise the measure for the further affecting subjects who are presumed to be most common in manufacturing industries.
