PURPOSE: Lower self-esteem, if present in enuretic children, might be an indicator of present and possible later psychological dysfunction. We tried to study the change of self-esteem before and after the treatment in children with nocturnal enuresis. MATERIALS AND METHODS: We recruited 32 enuretic children between september, 1998 and april, 2000. Mean age was 7.3 years old (range 4-12). We investigated the effect of self-esteem after 3 months treatment by Harter's self conception profile for children (SPPC) by total score and 6 subscales scores (scholastic competence, social acceptance, athletic competence, physical appearance, behavioral conduct and global self-worth). The patients were divided in two groups: the response group defined as greater than 50% reduction of wet night and the non response group defined as less than 50% reduction of wet night. A paired t-test was used for the improvement of Harter's SPPC at total score and subscales after treatment and student t-test was used for the comparison of the improvement of SPPC between groups. RESULTS: After treatment, the overall Harter's SPPC did not show statistically significant improvement. Among the 32 enuretic children, 22 children (69%) were in response group and 10 children (31%) were in non-response group. We could not find any statistically significant self-esteem change in Harter's SPPC in responders and also even in non-responders. CONCLUSIONS: Our data suggested that Harter's SPPC did not show significant improvement after treatment of enuresis.

Salmonella is one of the major pathogenic bacteria that cause food poisoning. This study investigated whether heat-killed as well as live Lactobacillus protects host animal against Salmonella infection. Live and heat-killed Lactobacillusacidophilus was administered orally to Sprague-Dawley rats for 2 weeks before the rats were inoculated with Salmonella. Rise in body temperature was moderate in the group that was treated with heat-killed bacteria as compared to the Salmonella control group. The mean amount of feed intake and water consumption of each rat in the heat-killed bacteria group were nearly normal. The number of fecal Salmonellae was comparable between the live and the heat-killed L. acidophilus groups. This finding shows that L. acidophilus facilitates the excretion of Salmonella. Moreover, the levels of pro inflammatory cytokines, including tumor necrosis factor (TNF)-alpha and interleukin (IL)-1 beta, in the heat-killed L. acidophilus group were significantly lower when compared to the levels in the Salmonella control group. These results indicate that nonviable lactic acid bacteria also could play an important role in preventing infections by enteric pathogens such as Salmonella.

PURPOSE: Outbreaks of mumps continue to occur, even though the number of patients diagnosed of mumps has decreased considerably with the widespread use of vaccine. The accurate diagnosis of mumps is needed to understand the epidemiology of mumps and analyse the safety and effectiveness of vaccine. Therefore, we attempted to appraise the accuracy of provisional diagnosis of mumps in clinical practice by measuring mumps specific antibody. METHODS: Thirty-six patients with presumptive diagnosis of mumps were enrolled from four university hospitals. Medical history including MMR vaccination was obtained, and anti-mumps IgM antibody test(ELISA. Denka Seiken Co., Ltd., Tokyo, Japan), complete blood counts and amylase were measured. RESULTS: Among 36 patients presumptively diagnosed of mumps, anti-mumps IgM antibody was positive in 14 patients(38.8%), negative in 20(55.5%) and equivocal in 2(5.5%). In two patients who were not vaccinated against mumps, one had anti-mumps IgM antibody and the other did not. All four patients, vaccinated with MMR twice after their first birthday did not have anti-mumps IgM antibody. The sites of involved glands and the associated localized as well as systemic symptomatologies were not different between patients with anti-mumps antibody and those without. The proportion and degree of increment of serum amylase level were not different between the two groups. CONCLUSION: A significant number of patients with provisional diagnosis of mumps appear to be due to other causes. Amylase, commonly used in clinical practice, does not differentiate mumps from other illnesses involving the parotid glands. Mumps can be accurately diagnosed only by laboratory tests including anti-mumps antibody. The two-dose MMR vaccination program needs to be reinforced.

Nitrogen dioxide (NO2) has been regarded as one of the main elements among air pollutants, and we measured NO2levels of near gas range, kitchen, living room and outdoor on 489 apartments in Pusan area. NO2were sampled by using Palmes tubes (diffusion tube sampler) during August 16-25, 1995 (summer) and January 15-29, 1996 (winter), respectively. Authors wanted to know comparison of NO2levels in summer and winter, NO2 levels categorized by variables, and variables affected to NO2levels. According to this study, we conducted to establish the degree of indoor-outdoor air pollution of urban apartments in Korea and methods to reduce indoor air pollution. The results of this study were summarized as follows: 1) Mean NO2levels of near gas range, kitchen, living room, and outdoor were 25.9+/-10.0 ppb, 23.3+/-8.0 ppb, 19.9+/-6.1 ppb, and 19.0+/-6.0 ppb in summer, and 34.5+/-16.8 ppb, 28.2+/-13.4 ppb, 25.3+/-12.5 ppb, 21.8+/-9.8 ppb in winter, respectively. 2) Mean NO2levels according to the floor levels were not significantly different in summer, and in winter, NO2levels were decreased as the floor levels were increasing, but those were increased above 16th floor. 3) Variables showing significant correlation (p<0.05) with NO2levels were as follows; Summer: floor level, family size, number of family during a meal, number using gas range during rice cooking per day, and natural ventilation. Winter: floor level, family size, number of person who have been respiratory disease in a house, number of family during a meal, total number of meals, and number using gas range during rice or side-dish cooking per day. 4) We suggest that the methods of reducing indoor NO2levels are ventilation during cooking, complete combustion, decreasing number and time of cooking, and substitution of fuels.

PURPOSE: The normal values for lung resistance and lung capacity of children, as determined by impulse oscillometry (IOS), are different for children of different ethnicities. However, reference values there is no available reference value for Korean preschool children have yet to be determined. The aim of the present study was to determine the normal ranges of IOS parameters in Korean preschool children. METHODS: A total of 133 healthy Korean preschool children were selected from 639 children (aged 3 to 6 years) who attended kindergarten in Seongnam, Gyeonggi province, Korea. Healthy children were defined according to the European Respiratory Society (ERS) criteria. All subjects underwent lung function tests using IOS. The relationships between IOS value (respiratory resistance (Rrs) and reactance (Xrs) at 5 and 10 Hz and resonance frequency (RF)) and age, height, and weight were analyzed by simple linear and multiple linear regression analyses. RESULTS: The IOS success rate was 89.5%, yielding data on 119 children. Linear regression identified height as the best predictor of Rrs and Xrs. Using stepwise multiple linear regressions based on age, height, and weight, we determined regression equations and coefficients of determination (R2) for boys (Rrs5=1.934-0.009xHeight, R2=12.1%; Xrs5=0.774+0.006xHeight-0.002xAge, R2=20.2% and for girls (Rrs5=2.201-0.012xHeight, R2=18.2%; Xrs5=-0.674+0.004xHeight, R2=10.5%). CONCLUSION: This study provides reference values for IOS measurements of normal Korean preschool children. These provide a basis for the diagnosis and monitoring of preschool children with a variety of respiratory diseases.

Fetal umbilical blood was obtained by cordocentesis guided by transabdominal USG in 276 fetuses at more than 14 weeks gestation. Fetal daryotyping was carried out in 7 cases of cordocentesis-failed group by cardiocentesis (3 cases) and amniocntesis (4 cases). The 46 cases in 263 fetuses revealed abnormal karyotypes (17.5%). There were 24 cases of numerical abnormality, 14 cases of structural abnormality, 5 cases of mosaicism, and 3 miscellaneous abnormalities. In the numerical abnormalities, trisomies and sex chromosomal abnormalities were 22 and 2 case, respectively. In 22 trisomy cases, there were 16 cases of trisomy of 18 chromosome which is the most common single cytogenetic abnormality in cordocentesis. The most common associated anomalies in trisomy 18 was congenital heart anomaly, in which vetricular septal defect was the most common. Pregnancy outcome is as follows: 22 cases of termination of pregnancy, 9 cases of still-birth, 5 cases of neonatal death, three living babies and 7 cases lost to follow-up.

BACKGROUND: Curcumin, a yellow ingredient of turmeric (Curcuma longa Linn, Zingiberaceae), has long been used in traditional folk medicine in the management of inflammatory disorders. Although curcumin has been reported to inhibit experimentally-induced colitis and carcinogenesis, the underlying molecular mechanisms remain largely unresolved. METHODS: Murine colitis was induced by dextran sulfate sodium (DSS) which mimics inflammatory bowel disease. Curcumin or tetrahydrocurcumin was given orally (0.1 or 0.25 mmol/kg body weight daily) for 7 days before and together with DSS administration (3% in tap water). Collected colon tissue was used for histologic and biochemical analyses. RESULTS: Administration of curcumin significantly attenuated the severity of DSS-induced colitis and the activation of NF-κB and STAT3 as well as expression of COX-2 and inducible nitric oxide synthase. In contrast to curcumin, its non-electrophilic analogue, tetrahydrocurcumin has much weaker inhibitory effects. CONCLUSIONS: Intragastric administration of curcumin inhibited the experimentally induced murine colitis, which was associated with inhibition of pro-inflammatory signaling mediated by NF-κB and STAT3.

This report presents the latest statistics on the stroke population in South Korea, sourced from the Clinical Research Collaborations for Stroke in Korea-National Institute for Health (CRCS-K-NIH), a comprehensive, nationwide, multicenter stroke registry. The Korean cohort, unlike western populations, shows a male-to-female ratio of 1.5, attributed to lower risk factors in Korean women. The average ages for men and women are 67 and 73 years, respectively.Hypertension is the most common risk factor (67%), consistent with global trends, but there is a higher prevalence of diabetes (35%) and smoking (21%). The prevalence of atrial fibrillation (19%) is lower than in western populations, suggesting effective prevention strategies in the general population. A high incidence of large artery atherosclerosis (38%) is observed, likely due to prevalent intracranial arterial disease in East Asians and advanced imaging techniques.There has been a decrease in intravenous thrombolysis rates, from 12% in 2017–2019 to 10% in 2021, with no improvements in door-to-needle and door-to-puncture times, worsened by the coronavirus disease 2019 pandemic. While the use of aspirin plus clopidogrel for noncardioembolic stroke and direct oral anticoagulants for atrial fibrillation is well-established, the application of direct oral anticoagulants for non-atrial fibrillation cardioembolic strokes in the acute phase requires further research. The incidence of early neurological deterioration (13%) and the cumulative incidence of recurrent stroke at 3 months (3%) align with global figures. Favorable outcomes at 3 months (63%) are comparable internationally, yet the lack of improvement in dependency at 3 months highlights the need for advancements in acute stroke care.
