Purpose : The purpose of the present study was to access the prevalence of orthostatic dysregulation(OD) and the frequency of each category for major and minor criteria among elementary school students using the OD questionnaire. Methods : We carried out inquiry by questionnaire as to the frequency of OD among two elementary schools with 725 students, 10 to 12 years of age, residing in Gwangju, Korea. The questionnaire was made according to criteria proposed by the Japan OD Study Group. Results : Of the 725 students(male 390; female 335) questioned, the OD was found in 338 students (53.5 percent). Prevalence of OD in males(59.2 percent) was significantly higher than in females(46.8 percent)(P<0.05). Palpitation with slight exercise(95.9 percent) was the most frequent major symptom. Headaches(85.8 percent) were the most frequent minor symptom among cases of OD. Conclusion : The prevalence of OD in elementary school students in this study(53.5 percent) was higher than in other studies. Contrary to studies from other countries, the male to female ratio was reversed. Because the diagnostic criteria seem to be dependent on subjective reporting of the symptoms, a newer diagnostic system based on more objective findings should be established.

Background: Gastric cancer is the second leading cause of cancer-related deaths worldwide and infection with H. pylori is considered essential for its development. Helicobacter pylori infects more than 50% of the world's population with higher prevalence in developing countries than developed countries. The prevalence of H. pylori varies in different societies and geographical locations. The objectives of this study were to estimate the seroprevalence and determine the risk factors of H. pylori infection in dyspeptic patents in Ethiopia. Materials and Methods: A cross-sectional study involving 209 dyspeptic patients was carried out from February 15 to April 30, 2013. Five to ten ml venous blood was collected from each dyspeptic patient and analyzed for detection of Helicobacter pylori immunoglobulin (IgG). The socio-demographic characteristic, hygienic practices, alcohol consumption, sources of drinking water and types of latrine were also obtained with a pre-tested questionnaire. Results: The overall seroprevalence of Helicobacter pylori was 72.2%. There was statistically significant difference in the prevalence of H. pylori among age groups (p=0.02). Seroprevalence of H. pylori was higher in those patients who used unprotected surface water (76.4%) than those with access to piped tap water (65.9%). There was also statistically significant differences in prevalence of H. pylori with the habit of hand washing before meal (p=0.01) and alcohol consumption (p=0.001). Conclusions: The prevalence of H. pylori was high in the study area and increased with age of dyspeptic patients. Alcohol consumption and the type of drinking water are risk factors that have associations with the prevalence of H. pylori. Molecular epidemiological techniques can show a true picture of H. pylori and improvement in the drinking water quality is recommended.

Purpose: The purpose of this study was to identify the effect of predictive factors related to family strength and develop a structural equation model that explains family strength among married working women. Methods: A hypothesized model was developed based on literature reviews and predictors of family strength by Yoo. This constructed model was built of an eight pathway form. Two exogenous variables included in this model were ego-resilience and family support. Three endogenous variables included in this model were functional couple communication, family stress and family strength. Data were collected using a self-report questionnaire from 319 married working women who were 30~40 of age and lived in cities of Chungnam province in Korea. Data were analyzed with PASW/WIN 18.0 and AMOS 18.0 programs. Results: Family support had a positive direct, indirect and total effect on family strength. Family stress had a negative direct, indirect and total effect on family strength. Functional couple communication had a positive direct and total effect on family strength. These predictive variables of family strength explained 61.8% of model. Conclusion: The results of the study show a structural equation model for family strength of married working women and that predicting factors for family strength are family support, family stress, and functional couple communication. To improve family strength of married working women, the results of this study suggest nursing access and mediative programs to improve family support and functional couple communication, and reduce family stress.

Purpose: Numerous indices have been proposed to analyse wound healing in oral soft tissues, but each has specific shortcomings. A new method of analysis, the Early Wound Healing Score (EHS), was evaluated in the present study. The aim was to assess more accurately early healing by primary intention of surgical incisions in periodontal soft tissues. Methods: Twenty-one patients were treated with different surgical procedures comprising 1 or 2 vertical releasing incisions as part of a surgical access flap. Twenty-four hours after surgery, early wound healing at the vertical releasing incisions was assessed using the EHS. This score assessed clinical signs of re-epithelialization (CSR), clinical signs of haemostasis (CSH), and clinical signs of inflammation (CSI). Since complete wound epithelialization was the main outcome, the CSR score was weighted to be 60% of the total final score. Accordingly, a score of 0, 3, or 6 points was possible for the assessment of CSR, whereas scores of 0, 1, or 2 points were possible for CSH and CSI. Higher values indicated better healing. Accordingly, the score for ideal early wound healing was 10. Results: Thirty vertical releasing incisions were assessed in 21 patients. At 24 hours after incision, 16 vertical releasing incisions (53.33%) received the maximum score of CSR, while 6 cases (20%) received an EHS of 10. None of the cases received 0 points. Conclusion: The EHS system may be a useful tool for assessing early wound healing in periodontal soft tissue by primary intention after surgery.

Background: We wished to analyse patterns of use of needle biopsy procedures by BreastScreen Australia (BSA) accredited programs to identify areas for improvement. Design: BSA services provided anonymous data regarding percutaneous needle biopsy of screen detected lesions assessed between 2005-2009. Results: 12 services, from 5 of 7 Australian states and territories provided data for 18212 lesions biopsied. Preoperative diagnosis rates were 96.84% for lesion other than microcalcification (LOTM) and 93.21% for microcalcifications. At surgery 97.9% impalpable lesions were removed at the first procedure. Of 11548 Microcalcification (LOTM) biopsied, 46.9% were malignant. The final diagnosis was reached by conventional core biopsy (CCB) in 72.46%, FNAB in 21.33%, VACB in 1.69% and open biopsy in 4.52% of lesions. FNA is being limited to LOTM with benign imaging After FNAB, core biopsy was required for 38% of LOTM. In LOTM the mean false positive rate (FPR) was 0.36% for FNAB, 0.06% for NCB and 0% for VACB. Diagnostic accuracy was 72.75% for FNAB and 92.1% for core biopsies combined. Of 6441 microcalcifications biopsied 2305 (35.8%) were malignant. Microcalcifications are being assessed primarily by NCB but 6.57% underwent FNAB, 45.6% of which required NCB. False positive diagnoses were rare. FNR was 5% for NCB and 1.53% for VACB. Diagnostic accuracy was 73.52% for FNAB, 86.29% for NCB and 88.63% for VACB. Only 8 of 12 services had access to VACB facilities. Conclusions: BSA services are selecting lesions effectively for biopsy and are achieving high preoperative diagnosis rates. Gaps in the present accreditation standards require further consideration.

Dental Pulp Stem Cells are superior to other types of adult stem cell. Because of teeth are easy to access and are extracted throughout life. A supernumerary tooth is an important clinical problem found in various populations of the world. The incidence of supernumerary teeth varies depending on the literature source. Pediatric dentists are routinely extracted them. However, no studies have been reported regarding Dental Pulp stem cells in a supernumerary tooth, and we failed to note that a valuable source of human stem cell. Herein, we tried to show that a supernumerary tooth contains cells that display the characteristic features of stem cells.

Purpose: We evaluated the status of patients enrolled in South Korea's pediatric palliative care pilot project based on the experience of a single center. This study examined factors related to end-of-life services and differences in medical costs. Methods: The medical records of 120 patients referred by a pediatric palliative care team were analyzed retrospectively. Data from July 1 to February 28, 2022 were collected and analyzed using the chi-square test and the Mann-Whitney U test. Results: Volunteer programs and psychological support (100%), family support and education (99.2%), and financial support through institutional linkage (62.5%) were provided to the participants. In the deceased group, there were no significant differences in general characteristics, which included age, gender, primary disease, religion, duration of hospitalization in an intensive care unit (ICU) and non-intensive care unit (non-ICU). However, the ICU group had fewer opportunities to access individual pain and physical symptom management than the non-ICU group and there were limitations in linking with external resources. Medical expenses were significantly different for the ICU group, with a 3-times higher average cost than the non-ICU group. Conclusion: Although an individualized approach is needed for each patient in pediatric palliative care, psychosocial care is essential. In addition, if early intervention for end-of-life pediatric patients is available from a palliative care team, the cost burden of medical care for patients and their families should be minimal.

To study the pattern of prenatal care utilization and its determinants in rural Korea, 976 mothers (65.5%) out of 1,489 living mothers in Chinyang, Sachon and Hapchon Counties in Kyongsangnam Province who had delivered a baby between July 1, 1990 and June 30, 1991 were interviewed by the Myon health workers from January 3 through February 15, 1992. The Anderson's behavioral model for health service utilization was applied to develop the frames for analysis. The dependent variable was a number of prenatal care visits. And the independent variables included In the model were the variables pertaining to the predisposing, enabling, medical need and other components. The proportion of mother who had ever received the prenatal care service for the index pregnancy was 97.3%. However, the proportion of mothers who had made more than 10 visits was only 20.6%, which indicated that majority of mothers had paid far less visits than recommended $10{\sim}12$ visits for each normal pregnancy. The low utilization of prenatal care services (none or less than 4 visits) was related to mother's low educational level, the high birth order, beneficiary of the medical aid, the absence of clinic in the community, no diagnosed disease of mother during pregnancy, and mothers engaged in farming. Inequity of access seemed to exist because social structure variables and the variables of enabling component were important predictors. And there seemed to be high mutability in equalizing the distribution of prenatal care services because the variables of enabling component such as type of medical security and whether there was a clinic or not in the community were substantially important.

The activity of brush border enzymes (sucrase, lactase and maltase) in the piglet small intestine was evaluated as well as piglet performance during the weaning period in the present study. There were two treatment groups: Piglets of six litters were fed dry feed plus milk replacer (Group M) and of six litters fed dry pelleted feed (Group C). One piglet from each litter was sacrificed on day 3 before weaning, and day 3, 10 and 17 postweaning, respectively. Providing milk replacer caused an increased piglet live weight at weaning (p<0.001) and until termination of the experiment (p<0.001). A slightly higher (p<0.16) level of protein was measured in the jejunum of group M piglets as compared with group C piglets. Before weaning the activity of lactase was high in the jejunum of group C piglets. The activity of lactase in the jejunum was lowered in the jejunum of group C piglets and in distal jejunum of group M piglets during the postweaning period as compared with pre-weaning period (p<0.05). Lowered activity of lactase in the distal jejunum of piglets was found at day 10 and 17 postweaning, respectively. No treatment differences were found in the activity of lactase in the piglet jejunum. No treatment differences were seen in the activity of maltase and sucrase in the piglet jejunum also. However, weaning caused a higher activity of sucrase in the distal jejunum of group M piglets as compared with pre-weaning period. In conclusion, providing milk replacer to piglets caused an improved growth performance. Feeding milk replacer did not influence the activity of lactase, maltase and sucrase in the jejunum of piglets. Weaning resulted in a markedly lowered activity of lactase, while no dramatic changes in the activity of maltase took place during the period around weaning.

Purpose: Some of the adolescent drinks more sugar-sweetened beverages. However, there is little evidence on the effect of eating behavior on emotional state and neurochemical changes under stress, especially on the levels of typical inhibitory neurotransmitters and gamma-aminobutyric acid. This article demonstrates that sucrose or saccharin drink reduces stress-related behavior responses and GABAergic deficits in adolescent rats. Methods: We randomly assigned 7-weeks-old Sprague-Dawley male rats to three groups: control group (Control), restraint stress only group (Stress), and restraint stress with unrestricted access to saccharin solution (Saccharin) and sucrose solution (Sucrose) as a positive control. We evaluated both anxious and depressive moods using an open field test and forced swim test, respectively. Using western blot analyses, the expression of a GABA-synthesizing enzyme, glutamate decarboxylase-67 (GAD67) and GABAergic markers, including calbindin and parvalbumin was assessed in the prefrontal cortex and the amygdala. Results: We found that both the drinks alleviated anxiety and depressive moods, induced significant attenuation in GAD67 level, and reduced calbindin level under stress in the prefrontal cortex and the amygdala. Conclusion: The results provide an understanding of the effect of sucrose or saccharin drink on stress-related responses. We propose the consumption of sweet drinks as a plausible strategy to alleviate stress-related alterations in adolescents.
