The purpose of this study was to examine 1) whether the relationship between smoking and obesity was linear or non-linear (specifically U-shaped), and 2) if this relationship was proved to U-shaped, whether it was due to the in teraction of the effects of smoking and alcohol consumption on obesity. The present study was performed using cross sectional data taken from the medical records of 400 male patients. Data was analyzed using linear and curvilinear estimation, Fisher's exact test, and two-way ANCOVA. The relationship between smoking intensity and BMI was able to be explained significantly by a quadratic model, rather than by linear model. As has been shown in other studies, this relationship was parabolic (or U-shaped), though it was not particularly remarkable. This U-shaped relationship appeared to be due to the interaction of the effects of smoking intensity and alcohol consumption on BMI. On the other hand, the relationship between smoking intensity and the percentage of body fat was able to be explained significantly by a linear as well as a quadratic model. Additionally, the interaction effect between smoking intensity and alcohol consumption did not influence the percentage of body fat significantly. In conclusion, there is no doubt that smoking and obesity are both serious health hazards. Based on the results of this and other studies, it can be confirmed that heavy smoking has a positive relationship with obesity. Therefore, the health benefits of smoking cessation, as well as the correction of unhealthy habits such as alcohol consumption should be clearly emphasized.

BACKGROUND/AIMS: Although it has been known that folate will participate in colorectal carcinogenesis, the relationship between blood folate level and colorectal cancer is less consistent. The blood folate level does not reflect the systemic folate status. By contrast, serum homocysteine has become a sensitive marker for the folate deficiency. We attempted to explain the correlation between folate and colorectal cancer according to the serum homocysteine level. METHODS: We reviewed the clinical records, including alcohol history of 184 patients taking the colonoscopy and measurement of the serum homocysteine level at Health Promotion Center from 2001 to 2002. One hundred fifty-one of 184 were included, excluding 33 patients with previous history of colonic polyp, cerebrovascular, cardiovascular attack and thromboembolism. They were divided into the normal control (n=111) and the adenomatous polyp group (n=40). We had selected the colorectal cancer group (n=50) from the collection list of the tissue and blood bank less than 3 months storage interval. RESULTS: There was no significant difference in the mean serum homocysteine level among three groups. However, in the subjects with high alcohol consumption, there was a significant difference in the mean serum homocysteine between the normal control (n=7) and the adenomatous polyp group (n=9) (10.2 vs 15.1 micromol/L, p<0.05). CONCLUSIONS: There was no correlation of serum homocysteine and colorectal tumor. However, in the subjects with high alcohol consumption, high serum homocysteine might be related to the development of adenomatous polyp.

OBJECTIVETo estimate the reference value for micronucleus frequency of peripheral blood lymphocytes in general Chinese population, and to guide the genotoxicity evaluation and risk analysis for populations exposed to environmental or occupational chemicals.

METHODSA fulltext search was performed in CNKI with the key words of "micronucleus" and "human", and PubMed was searched with "cytokinesis-block micronucleus","CBMN","humans", and "adults", to obtain the articles published at home and abroad from 2001 to 2014 in which cytokinesis-block micronucleus (CBMN)assay was applied for micronucleus detection and populations not exposed to genotoxins were established as a control. Monte Carlo simulation was performed based on the micronucleus frequency, standard deviation, and sample size provided in these articles to calculate the micronucleus frequency for general population and to analyze the influence of sex, smoking, and drinking on micronucleus frequency.

RESULTSA total of 23 articles were included in the final analysis. The minimum mean micronucleus frequency was 0.39‰, and the maximum mean micronucleus frequency was 25.3‰. There were 1623 subjects in the control group in total (range 22~178, mean 70.6). Monte Carlo simulation was performed 100 times, and the mode of micronucleus frequency was 0 or 1‰; the values of P0, P25, P50 , P75, and P95 were 0‰, 1‰, 2‰~3‰, 5‰~6‰, and 14‰~19‰, respectively; the mean value was 4.36‰(range 4.22‰~4.57‰). With the application of one-sided 95% range(x±1.64 s), the upper limit of the range of reference value was calculated to be 13.46‰~14.75‰.

CONCLUSIONThe micronucleus frequency of peripheral blood lymphocytes in general Chinese population is 4.36‰, the interquartile range is 1‰~5‰ or 1‰~6‰, and the upper limit of reference value is 14.17‰. The factors of living area, sex, smoking, and drinking may influence micronucleus frequency.

Many researchers have used cue reactivity paradigm to study alcohol craving. But the difference of craving response to drinks between alcoholic patients and social drinkers was little evaluated. To investigate characteristics of alcohol-related visual cues which induce alcohol craving in alcoholism, we examined the response of subjects to alcohol-related cues considering qualitative aspects. The authors developed 27 photographs related to alcohol as candidate visual cues. Thirty five patients with alcohol dependence, 35 heavy drinkers and 35 social drinkers were shown these pictures and asked to rate these 6 pictures in order of inducing alcohol craving the most. 'A glass of Soju' and 'A Party scene' were chosen as the alcohol-related visual cues which induced craving the most in the patients and heavy drinkers, respectively. The results suggest that the patients with alcohol dependence are more absorbed by alcohol without drinking context such as an atmosphere or situation involving drinking. Heavy drinkers may experience craving in anticipation of being in a drinking situation.

BACKGROUND: The diagnostic criteria for bathtub drownings are not standardized, and the risk factors associated with bath-related deaths are unclear. METHODS: We analyzed a Korean nationwide database of bath-related deaths that occurred between January 2008 and December 2015. Eighty-four cases were enrolled after reviewing 31,123 autopsy records. RESULTS: The subjects' ages ranged from 18 to 91 years, with a mean age ± standard deviation of 61.3 ± 16.0 years. Bath-related deaths in the winter were approximately 4.6-fold greater than those in the summer. Of the 84 subjects, the primary cause of death in 57 (67.9%) was drowning in the bath; 24 (28.6%) drowned of other causes such as natural diseases, and 3 (3.6%) died of acute alcohol intoxication. We analyzed water-inhalation signs to establish criteria for bathtub drowning diagnosis. There were significantly higher incidences of hyperinflated lungs, water in the sphenoid sinus and stomach/duodenal contents, and Paltauf's spots (subpleural hemorrhage) in bathtub-drowned subjects compared to non-drowned individuals (P < 0.01). Multiple signs of water inhalation were significantly associated with bathtub drowning (P < 0.01). The two leading contributory causes of bath-related death were cardiovascular diseases and alcohol intoxication (binge drinking before bathing). CONCLUSION: The diagnosis of bath-related deaths could present considerable medico-legal problems; therefore, a comprehensive autopsy with a thorough scene investigation can clarify the cause of death in these situations. Preventive strategies for reducing such deaths should target alcohol drinking before bathing and long soaking times in bathtubs, especially among elderly individuals with preexisting cardiovascular diseases.

PURPOSE: The purpose of this study was to identify factors affecting the social competence of school-aged children according alcohol consumption by their parents. METHODS: The participants were 558 5th grade elementary school students. Data were collected using structured questionnaires from September 17 to October 2 2013, and analyzed using descriptive statistics, chi2-test, t-test, ANOVA, Pearson correlation coefficients, and Stepwise multiple regression analysis with the SPSS PC+ 21.0 program. RESULTS: Participants were classified into three groups according to alcohol use; Non-use parent group (52.7%), social use parent group (31.0%), and problem use parent group (16.3%). Participants whose parents were problem users had significantly lower scores on emotional awareness and expression (F=14.45, p<.001), social support (F=5.82, p=.003), and social competence (F=16.33, p<.001) compared to students in the other two groups. In school-aged children with parents who were alcohol abusers, the variables that predicted social competence was friend support (66.0%). CONCLUSION: These results emphasize the importance of focusing on the crucial role of peer support in the development of social competence in school-aged children of parents who abuse alcohol. Further, for these children, interventions aimed at improving social support and children's emotional awareness and expression may be most beneficial.

BACKGROUND: Gastric cancer is the second most common cancer in Korea. Fatigue is a common symptom among cancer survivors. The aim of this study was to identify factors associated with fatigue in gastric cancer survivors. METHODS: Data were analyzed from 199 gastric cancer survivors who visited a cancer survivor outpatient clinic from July 2013 to June 2014. Patients were surveyed using a questionnaire containing a fatigue severity scale (FSS) and questions regarding associated symptoms. Participants were divided into fatigue (FSS) and non-fatigue groups based on FSS scores (> or =4 and <4, respectively). Age, sex, weight, body mass index, cancer stage, pathology, surgery type, chemotherapy, radiotherapy, comorbid disease, family history of cancer, smoking, alcohol consumption, exercise, and laboratory results were investigated. RESULTS: The fatigue and non-fatigue groups contained 42 and 157 survivors, respectively. Their mean age was 58 years, and the mean post-operative period was 6.58 years. Arthralgia (odds ratio [OR], 12.95; 95% confidence interval [CI], 3.21-52.34), dyspnea (OR, 10.54; 95% CI, 2.94-37.80), dyspepsia (OR, 8.26; 95% CI, 2.63-25.96), changed bowel habits (OR, 4.56; 95% CI, 1.09-19.11), anemia (OR, 3.18; 95% CI, 1.26-8.05), and regular exercise (OR, 0.31; 95% CI, 0.12-0.77) were significantly associated with fatigue in gastric cancer survivors, while weight, treatment, and depressive mood were not. CONCLUSION: Arthralgia, dyspnea, dyspepsia, bowel habit change, anemia, and regular exercise are associated with fatigue in gastric cancer survivors.

BACKGROUND/AIMS: Transforming growth factor beta1 (TGF-beta1) is a key cytokine in the production of extracellular matrix. A genetic polymorphism at codon 10 of the TGF-beta1 gene is associated with liver fibrosis. We investigated the effect of genetic polymorphisms at codon 10 on the development of alcoholic liver cirrhosis (ALC). METHODS: In total, 119 controls and 182 patients with ALC, were enrolled in the study. Clinical and laboratory data including total lifetime alcohol intake were collected at enrollment. The genotype at codon 10 was determined for each patient by single-strand conformation polymorphism. RESULTS: There were three types of genetic polymorphism at codon 10: homozygous proline (P/P), heterozygous proline/leucine (P/L), and homozygous leucine (L/L). Among the controls, the proportions of P/P, P/L, and L/L were 26.1%, 44.5%, and 29.4%, respectively in the ALC group, these proportions were 23.1%, 43.4%, and 33.5%, respectively. The genotype distribution did not differ between the controls and the ALC group. In the ALC group, age, total lifetime alcohol intake, and distribution of Child-Pugh class did not differ with the genotype. Of the male patients with ALC (n=164), the proportions of P/P, P/L, and L/L were 20.1%, 44.5%, and 35.4%, respectively the genotype distribution did not differ between the male controls and the male ALC patients. CONCLUSIONS: The genotype at codon 10 in TGF-beta1 does not appear to influence the development of ALC. Further study is needed to investigate other genetic factors that influence the development of ALC in patients with chronic alcohol intake.

PURPOSE: Cystic pancreatic neoplasms are rare, but interesting, because of their high cure rate. With the exception of pseudocysts and serous cystadenomas, which are always benign, these cystic neoplasms are either premalignant or malignant. However, there is no reliable clinical criteria for differential diagnosis, and the treatment plan may be confusing. METHODS: From October 1994 to November 1999, 60 cases, diagnosed as a cystic neoplasm preoperatively were reviewed retrospectively. The clinical findings of benign lesions (benign group) and those for malignant or premalignant tumors (malignant group) were compared. RESULTS: The postoperative pathology results indicate 10 serous cystadenomas, 13 mucinous cystic neoplasms, 11 solid and papillary neoplasms, 10 duct ectasias, 2 cystic islet cell tumors, 1 metastatic papillary carcinoma, 1 lymphepithelial cyst, 2 simple cysts, 6 pseudocysts, and 4 retension cysts without malignancy. The mean age of the patients was 48.6 years, and the male-to-female ratio was 5 to 7. The accuracy of CT for diagnosing the malignancy of malignant tumors was 37.8% (14/37) and that of US was 22.2% (4/18). The rate of tumors having malignant potential was 71.7% (37/60). The mean size of the tumors in the benign group was smaller than that in the malignant group (p=0.014). There was a higher proportion of females in the malignant group than in the benign group (p=0.001). Heavy alcohol consumption was found more frequently in the benign group (p=0.021). There were no differences in the other clinical findings. The mortality rate of the operations was 0%, and the morbidity rate was 18%. CONCLUSION: Since it is difficult to determine the precise tumor type of a cystic pancreatic neoplasm preoperatively, all these lesions should be treated with surgical resection in order to identify and remove the malignant or premalignant neoplasms early. However, if the operative risk is high, malignant risk factors having large sized tumor, especially more than 6 cm, female, and having no history of heavy alcohol consumption may be useful for deciding the treatment plan.

OBJECTIVETo investigate effects of cigarette, alcohol consumption and sauna on sperm morphology.

METHODS602 cases of male infertility were selected from our case database, who were divided into three subgroups: smoking (243) , drinking(224), sauna(135) and those without any of the above habits were taken as the corresponding controls. The sperm morphology were analyzed by automated sperm morphology analyzer(ASMA). A questionnaire was voluntarily filled out by patients in order to investigate cigarette, alcohol consumption and sauna frequency.

RESULTSThe normal morphologic sperm rates in cigarette, alcohol consumption and sauna groups were lower than those in the corresponding control groups, respectively(P <0.05, P <0.001). Percentages of irregularity head sperm were higher than those in normal controls, respectively(P <0.05).

CONCLUSIONCigarette, alcohol consumption and sauna could affect sperm morphology, especially caused increasing of irregularity head sperm.
