PURPOSE: This study was done to investigate the effect of non-smoking campaign for subway workers on their health behavior such as smoking, drinking, and exercise. METHOD: The study was done on the subjects of 112 male employees for 3 years from 2003 to 2005 working at the Seoul Metropolitan Rapid Transit Corporation. However, the subjects decreased to 105 in 2004 and 111 in 2005 due to work transfer. The data were obtained through administering questionnaires. The non-smoking campaign was done with health education using various strategies and methods by an administrator-in-charge assisted by the community health center. RESULTS: Smoking rate and cigarette consumption decreased but there was no statistical significance. Smokers' frequency of drinking and exercise were higher than that of non-smokers, but there was no statistical significance. CONCLUSION: The result indicated the program was not effective to change the subjects' health behavior; therefore, tailored program considering the subjects is recommended.

PURPOSE: This study was designed to evaluate the effect of growth hormones on children with growth hormone deficiency(GHD) or idiopathic short stature(ISS). METHODS: Between January 1988 to July 2003, 45 patients(M26, F19) with GHD and 24 patients (M13, F11) with ISS were enrolled in this study. Height standard deviation score(Ht SDS) for chronological age(CA) and Ht SDS for bone age(BA) were obtained for each patient upon diagnosis and after growth hormone(0.1-0.15 IU/kg) was injected subcutaneously daily. RESULTS: Ht SDS for CA was -2.06+/-0.23 before treatment, -1.60+/-0.21 at one year, -1.52+/-0.23 at two years, -1.61+/-0.28 at three years, -1.60+/-0.31 at four years, and -1.54+/-0.32 at five years, showing a statistically significant increase for five years(P<0.05). Meanwhile, the values were -2.03+/-0.55 before treatment, -1.44+/-0.66 at one year, -0.14+/-1.06 at two years, -0.68+/-1.27 at three years, -1.16+/-0.96 at four years, and -1.37+/-0.94 at five years, in ISS, showing a statistically significant increase for the first three years(P<0.05) only. Ht SDS for BA in GHD was -0.53+/-0.19 before treatment, -0.39+/-0.18 at one year, -0.32+/-0.20 at two years, -0.43+/-0.22 at three years, -0.39+/-0.19 at four years, and -0.32+/-0.22 at five years, not showing a decrease, and the decrease in ISS was statistically not significant(P> or =0.05). CONCLUSION: Both groups exhibited significant increase in Ht SDS through growth hormone treatment, proving its efficacy. As for the evaluation of growth-related factors, the 1st year increase of Ht SDS was the most important factor in evaluation of growth effect in both groups. However, further study is required to investigate the effect of GH therapy on ISS.

PURPOSE: Early identification of causative agents in lower respiratory infection of pediatric patients can reduce morbidity and prevent an overuse of antimicrobials. Two kinds of multiplex polymerase chain reaction (PCR) and a commercial shell vial viral culture were performed to identify causative agents in pediatric patients. MATERIALS AND METHODS: Nasopharyngeal aspirates of 220 children diagnosed with viral pneumonia were obtained. Two kinds of multiplex PCR (Seeplextrade mark RV detection kit, and Labopasstrade mark RV detection kit), and a shell vial culture by R-Mix were performed. RESULTS: Positive samples from 220 total samples by two multiplex PCRs were 52.7% and 46.4%, respectively. We also cultured 103 samples that showed positive results of the adenovirus, influenza virus, parainfluenza virus, and respiratory syncytial virus (RSV) by two multiplex PCR. The RSV was most frequently detected in 53.0% (Seeplex) and 51.7% (Labopass) of patients. The detection rate of adenovirus (AdV) was 10.3% and 12.1%, influenza virus (IFV) A and B was 12.5% and 3.4%, and parainfluenza virus (PIFV) 1, 2, and 3 were 2.9% and 2.6%. Shell vial cultures showed concordant results with each multiplex PCR by 96.1% and 77.7%, respectively. Sequencing results were 90% consistent with multiplex PCR. CONCLUSION: Multiplex PCR showed more positivity than the shell vial culture and it can be an effective primary test. Other complementary efforts such as viral cultures and sequencing analysis could be considered, according to clinical and laboratory conditions.

PURPOSE: Antivenin is a standard therapy in snakebite victims. While the required antivenin dose can be easily estimated, based on the initial symptoms, this strategy may be unsuccessful if the initial symptoms progressively worsen. The purpose of this study was to identify the progression rate of the initial symptoms following snakebite and its associated factors. METHODS: The medical records of 44 patients treated for snakebite from give the actual dates of the study period were retrospectively examined. Thirty-two of these patients were enrolled. Demographic data, local wound grade and local effect score at initial presentation (G-0 and LES-0, respectively) and 12 hours after admission (G-12 and LES-12, respectively) were reviewed, along with laboratory data. RESULTS: The 32 patients had an average age of 54.0+/-14.5 years and were predominantly male (n=26) and presented mainly during summer. Compared to G-0 and LES-0, re-evaluated G-12 and LES-12 were significantly increased despite initial administration of proper antivenin dosage (p=0.001 and p=0.000, respectively). Total amounts of antivenin correlated with LES-12 (correlation co-efficiency 0.558, p<0.05). However, factors associated with symptom progression were not revealed. CONCLUSION: Initial snakebite symptoms might progressively worsen within hours despite acceptable initial antivenin therapy. Therefore, re-evaluation within several hours must be considered if when the initial snakebite symptoms are minimal or mild.

OBJECTIVES: To determine the health behavior practices and needs for health promotion in shift work pattern in subway workers. METHODS: Among 789 male subway workers divided into four groups, 191 day time workers, 187 station service men (3 groups, 2 turns), 204 rolling stock inspectors (3 groups, 2 turns) and 207 train operators (8 groups, 5 turns), we surveyed the health behavior and needs for health promotion by questionnaire. RESULTS: For obesity, blood pressure and total cholesterol, day time workers had the highest levels, while train operators had higher diseases of the liver and stomach than others. The station service men had the highest smoking rate and daily smoking amount. More than 80% of the respondents consumed alcohol, and the drinking amount was highest among the day time workers and the 8/5 shift train operators. Eighty-two percent of the station service men had irregular eating habits and 17.7% did not have any breakfast. In health promotion activities, exercise and restriction of one's favorite(smoking or drinking) were most preferred in the four groups of respondents. The priority of needs and participation for health promotion program was exercise programs, followed by stress management, cancer prevention program, weight control program, anti-smoking campaign, high blood pressure control program, and abstinence/moderation in drinking. CONCLUSION: As the health behavior practices differed relative to shift work patterns, it was suggested that a comprehensive health promotion program according to shift work pattern should be planned and implemented among subway workers.

PURPOSE: We investigated the factors influencing the time to reach full enteral feeding in very low birth weight infants. We compared the days of life to start tube or oral feeding, to regain birth weight, and to establish full enteral feeding in very low birth weight infants and determined the risk factors delaying full enteral feeding. METHODS: We reviewed the medical records of 214 newborn infants less than 1,500 g at birth, who were delivered at Chonnam National University Hospital from January 1, 1997 to May 31, 2000. These infants were divided into three groups by birth weight (less than 1,000 g, 1,000-1,249 g, and 1,250-1,499 g). Gestational age, birth weight, the days of life to start first tube or oral feeding, to regain bith weight and to reach full enteral feeding, and the possible risk factors delaying the progress of enteral feeding were analyzed. RESULTS: The gestational age was 29.69+/-2.33 weeks and the birth weight was 1,212+/-194.3 g. The time to start tube or oral feeding, to regain birth weight, and to establish full enteral feeding were significantly later and longer in the lower birth weight group. The time to reach full enteral feeding was related to the duration of mechanical ventilation and oxygen therapy, and was significantly longer in the infants with severe respiratory distress syndrome (RDS), chronic lung disease (CLD), apnea, intraventricular hemorrhage (IVH), cystic periventricular leukomalacia, sepsis/disseminated intravascular coagulopathy, ricketts, and total parenteral nutrition. CONCLUSION: The time to reach full enteral feeding was inversely related to the birth weight, and the risk factors for delayed full enteral feeding were the presence and/or the severity of diseases related to the prematurity such as the duration of mechanical ventilation and oxygen therapy, RDS, CLD, apnea, IVH, and sepsis.

PURPOSE: Growth patterns of colorectal carcinomas can be divided into polypoid growth (PG) and nonpolypoid growth (NPG). This study was intended to find characteristic clinicopathologic features and the expression status of p53, p21, and p16 with relation to growth patterns in colorectal carcinomas. METHODS: Sixty-one surgically resected colorectal carcinomas including 43 PG and 18 NPG carcinomas were reviewed in this study. Immunohistochemical stains for p53, p21, and p16 were done, and the results were analyzed with respect to growth patterns, and other prognosic parameters. RESULTS: PG carcinomas were significantly correlated with adenoma (p=0.0001), and with favorable histology group (p=0.04). On the contrary, NPG carcinomas were significantly correlated with unfavorable histology group (p=0.04). In NPG carcinomas, the frequency of positive expression of p53 was higher and the expression of p16 was lower than that of PG carcinomas. But there was no statistical significance (p=0.150, 0.210 respectively). The expression of p21 has no difference between NPG and PG carcinomas (p=0.953). CONCLUSIONS: As a result, it can be thought that the tendency of higher expression of p53 and lower expression of p16 in NPG carcinomas than in PG carcinomas may suggest more aggressive biologic behavior of NPG carcinomas.

PURPOSE: Recently, after patent ductus arteriosus (PDA) ligation in preterm infants, unexplained hemodynamic instabilities are reported. To determine the incidence, risk factors and clinical manifestations of hemodynamic instability after PDA ligation in very low birth weight (VLBW) infants. METHODS: This retrospective multicenter study enrolled 18 VLBW infants who underwent PDA ligation from January 2002 to February 2008. Hemodynamic instability defined as unexplained cardiopulmonary dysfunction with increased dependency on mechanical ventilation and decreased blood pressure. RESULTS: The mean gestational age and birth weight (BW) of all infants were 27(+)6+/-1(+6) weeks and 951+/-245 g. Hemodynamic instability group (HI) included seven infants (39%) and hemodynamic stability group (HS) included 11 infants (61%). Compared to HS, HI had lower BW (1,033+/-285 g vs. 821+/-126 g, P=0.048) and weight on operation day (1,195+/-404 g vs. 893+/-151 g, P=0.042), longer hospital days (105+/-29 vs. 141+/-39, P=0.038), more severe bronchopulmonary dysplasia (BPD), (no/mild/moderate/severe, 2/5/2/2 vs. 0/1/2/4, P=0.038) and higher preoperative FiO2 (0.29+/-0.06 vs. 0.38+/-0.09, P=0.02). One case of mortality due to sepsis, which was not associated with ligation, was observed among HS. CONCLUSION: The incidence of hemodynamic instability after PDA ligation in VLBW infants was 39%. Low BW, low weight on operation day and preoperative high FiO2 might be risk factors of hemodynamic instability after PDA ligation in VLBW infants. The hemodynamic instability could increase the severity of BPD and hospital days.
