  • BACKGROUND/OBJECTIVES: The prevalence of atopic dermatitis in infants is increasing worldwide. However, the nutrient intake status of infants with atopic dermatitis has not been studied properly. This study was conducted to compare the nutrient intake status of infants in the weaning period with atopic dermatitis by feeding type. MATERIALS/METHODS: Feeding types, nutrient intake status and growth status of 98 infants with atopic dermatitis from age 6 to 12 months were investigated. Feeding types were surveyed using questionnaires, and daily intakes were recorded by mothers using the 24-hour recall method. Growth and iron status were also measured. RESULTS: The result showed that breastfed infants consumed less energy and 13 nutrients compared to formula-fed or mixed-fed infants (P < 0.001). The breastfed group showed a significantly lower intake rate to the Dietary Reference Intakes for Koreans than the other two groups (P < 0.001). In addition, they consumed less than 75% of the recommended intakes in all nutrients, except for protein and vitamin A, and in particular, iron intake was very low, showing just 18.7% of the recommended intake. There was no significant difference in growth by feeding type, but breastfed infants showed a significantly higher rate of iron deficiency anemia (P < 0.001). CONCLUSIONS: Continuous management programs should be prepared for breastfed infants with atopic dermatitis, who are in a period when rapid growth takes place and proper nutrient intake is essential.

  • Background: ASC-US cases are managed according to the current American Society for Colposcopy and Cervical Pathology (ASCCP) guideline in which a human papillomavirus (HPV) test and repeat Pap smear are performed in the next 1 year. Colposcopy in cases of positive high risk HPV and persistent ASC-US or more in subsequent Pap smear is recommended. The HPV test is more expensive and still not currently a routine practice in Thailand. Objective: To identify the risk factors of persisted abnormal Pap smear and the colposcopic requirement rate in women with ASC-US. Materials and Methods: During 2008-2013, this study was conducted in Prapokklao Hospital, Chanthaburi, Thailand. Participants were women who attended gynaecology clinic for cervical cancer screening. Women who had cytological reports with ASC-US were recruited. During the study period, 503 cases were enrolled. Colposcopic requirement was defined as those who were detected with an ASC-US or more in subsequent Pap smears up to 1 year follow-up. Results: The colposcopic referral rate was 23.2 (85/365) percent at 12 months. Prevalence of cervical intraepithelial neoplasia (CIN) 2/3 was 3.3 (12/365) percent. Loss follow-up rate of subsequent Pap smear and colposcopic appointment were 27.4 (138/503) and 48.2 (41/85) percent, respectively. There was no invasive cancer. High risk factors for persisted abnormal Pap smears in subsequent test were premenopausal status, HIV infected patients and non-oral contraceptive pills (COC) users. Conclusions: Referral rate for colposcopy in women with ASC-US reports was rather high. Loss to follow-up rate was the major limitation. Immediate colposcopy should be offered for women who had high risk for silent CIN.

  • The Korean government launched the medicaid program for the poor people as a wing of the social development and welfare programs beginning in 1977 when the fourth 5-year national economic development program started. The charts of the medicaid recipients who visited Jonglo-Gu Health Center for the period from 1981 to 1983 were reviewed and analysed. Major findings from the analysis are as follows. 1. The medicaid recipients occupied 5.19% in 1981, 2.90% in 1982 and 2.00% among the total residents of Jonglo district in 1983, respectively. 2. The mean number of physician visits per person year of medicaid recipients who visited the Jonglo-Gu Health Center was 4.73 in 1981, 4.90 in 1982 and 4.41 in 1983, respectively. 3. The consultation/referral rate at the Jonglo-Gu Health Center was 2.65% in 1981, 1.77% in 1982 and 2.18% in 1983 while the rate at the department of family practice, Seoul National University Hospital was 3.18% in 1983. 4. Classifying into 17 major categories, the pattern of diseases of the poor outpatients who visited the Hallym College Medical Center both in 1981 and 1982 showed a statistically similar pattern of the 5,169 medicaid patients who visited the Jonglo-Gu Health Center in 1981 and 401 patients in 1983. 5. Classifying into 17 major categories, the disease of outpatient visits at the department of family practice, Seoul National University Hospital from 1st May, 1983 to 31s1 Oct., 1983 revealed statistically significant similarity with both the 5,169 medicaid patients in 1981 and the 401 patients sampled in 1983. 6. Classifying into 17 major categories, the diseases of community diagnosis at the Ihwa Dong, Jonglo-Gu also showed a statistically significant similarity with the 5,169 medicaid patients who visited the Jonglo-Gu Health Center in 1981. 7. Classifying into 17 major categories, the diseases of 5,169 medicaid patients at Jonglo-Gu Health Center in 1981 showed a statistically significant similar distribution with that of the 401 sampled medicaid patients at this center in 1983. 8. Among the medicaid patients who utilized the Jonglo-Gu Health Center in 1983, 401 sampled patients who are practicable routine urinalysis composed of 131 indigent group and 270 low-income group. The sample composed of 127 males and 274 females. There were more old patients than the young ones among the 401 sampled patients. 9. Age-adjusted prevalence rate of the hypertension computed by the direct method using estimated of midyear population of 1980 year as the standard is the highest in the Yonsei area and the lowest in the Shindongmyun. Furthermore age-adjusted prevalence rate was higher for males than that of females. 10. The group of hypertension patients using routine urinalysis profile composed of pyuria, hematuria, proteinuria and glycosuria is the most statistical significant, the pyuria alone is very significant, hematuria is significant and proteinuria is also significant.

  • Objectives: The goal of this study was to examine the association of various demographic and socioeconomic factors with risk factors for chronic kidney disease (CKD). Methods: We used nationally representative pooled data from the Korea National Health and Nutrition Examination Survey (KNHANES), 2007-2013. We estimated the glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease equation. We defined CKD as a GFR <60 mL/min/$1.73m^2$, and 1304 of the 45 208 individuals included in the KNHANES were found to have CKD by this definition. The outcome variable was whether individual subjects adhered to the CKD prevention and management guidelines recommended by the Korea Centers for Disease Control and Prevention. The guidelines suggest that individuals maintain a normal weight, abstain from alcohol consumption and smoking, manage diabetes and hypertension, and engage in regular exercise in order to prevent and manage CKD. Results: This study found that individuals with CKD were more likely to be obese and have hypertension or diabetes than individuals without CKD. In particular, male and less-educated CKD patients were less likely to adhere to the guidelines. Conclusions: Although the prevalence of CKD, as indicated by the KNHANES data, decreased from 2007 to 2013, the prevalence of most risk factors associated with CKD fluctuated over the same time period. Since a variety of demographic and socioeconomic factors are related to the successful implementation of guidelines for preventing and managing CKD, individually tailored prevention activities should be developed.

  • The tongue has been globally considered as an indicator of general health for millennia. This study aimed to determine the prevalence and distribution of tongue lesions in an Iranian population. In this retrospective study, data from 6,435 oral biopsy reports over a 22-year period (1992-2014) were retrieved from archives of Oral and Maxillofacial Pathology Department, Shahid Beheshti Dental School, Tehran, Iran. These reports were analyzed according to age, sex, type of lesion and location. Prevalence of tongue lesions were reported as percentages. Out of total oral lesions, 238 (3.7%) were found in the tongue, with the incidence peak (42%) being between 41-60 years. Men constituted 53% and women 47%of patients. The youngest patient was a 3-year-old girl with pyogenic granuloma and the oldest one was a 93-year-old man with squamous cell carcinoma (SCC). SCC was the most common (25%) lesion generally found in the lateral border of the tongue with a male predilection. The second and third most prevalent lesions of the tongue were benign keratosis (frictional keratosis) (13.4%) and leukoplakia (13%).White-red lesions (38.6%) were the most frequent subgroup followed by neoplastic lesions (28%). Moreover, irritation fibroma, non-specific ulcers, squamous papilloma, and hemangioma were found as the most frequent lesions in their related subgroups.Given the high rate of SCC of the tongue in Iranian patients, this area should be examined more carefully by dental practitioners and physicians.

  • Stomachs from 3,354 fattening pigs were examined at slaughter during the period from September 1980 to August 1981. Pigs of both sexes and $Landrace{\times}Hampshire$ crossbreds were included in the present studies, and they weighed about 60-120kg. Gross pathologic alterations of the stomach were classified as normal, epitnelial change, erosion, ulcer and scar formation. Representative tissue sections were taken from the stomach lesions at random and fixed in 10% buffered formalin. Cut sections were stained with hematoxylin and eosin, and examined histopathologically. The results obtained in the present studies were as follows. 1. In the seasonal prevalence of gastric ulceration, severe ulceration with erosion was shown during the Autumn and Winter, whereas mild ulceration was mainly shown during the Spring and Summer. 2. Of the 3,354 stomachs of the pigs, 20.8% were found to be normal. Of the rest, 40% had epithelial changes, followed by erosion (24.7%), ulcer (13.6%) and scar formation (0.9%), respectively. 3. In the prevalence of ulcers in the different regions of the stomach, the fundic region had the highest rate (61.6%) of ulceration, followed by cardiac (21.7%), esophageal (15.0%) and pyloric region (1.7%). 4. The principal gross changes were severe epithelial changes with keratotic proliferation in the esophageal region, and in the fundic region severe folding of the stomach wall was covered with bloody mucous exudates. 5. Main histopathological changes were inflammatory cell infiltrations in most cases, hemorrhages in acute ulcers and prominent proliferation of granulation tissues in chronic ulcers.

  • Purpose: This study aimed to identify occupational stress and health problems as well as turnover reasons among leavers in novice nurses and to estimate factors which might affect turnover by comparing them to stayers. Methods: In this study, secondary analysis of data gathered from the Shift Work Nurse's Health and Turnover studies, was carried out. The data were collected from 204 stayers who have been working for 18 months since 2018 and 48 leavers who left within the same period at two tertiary hospitals in Seoul. The reasons for turnover, occupational stress, and 8 types of health problems were recorded. The data were analyzed using SAS 9.4 to obtain descriptive statistics. In parallel, Pearson's chi-squared test, Fisher's exact test, and independent t-test were also conducted. Results: The main reasons for turnover were job stress and difficult interpersonal relationships in the workplace. Occupational stress of leavers was higher than stayers, especially in the subscales of interpersonal conflict, organizational system, lack of reward, and occupational climate. Among the 8 types of health problems, the depression prevalence of leavers was higher compared to stayers and showed marginal significance. Unexpectedly, the sleep disturbance prevalence of stayers was significantly higher compared to leavers. Conclusion: To reduce the turnover rate of novice nurses, education on how to cope with occupational stress is needed. A customized program for novice nurses to overcome the difficulties of interpersonal relations would be helpful.

  • Carbon Monoxide poisoning is one of the most serious Public health problems in Korea. The incidence rate. officially reported has been known to be the highest in the world. This high incidence is mainly due to the wide prevalence of anthracite coal briquette as the domestic fuel for unique Korean heating system called 'ondol,' The coal briquette gas contains around 3-5% of Carbon Monoxide. A nation-wide effort to eliminate or reduce this serious hazards has produced little effect and the most hospitals are offering very ineffective measures such as oxygen inhalation through nasal catheter. Author has believed that this preventable accident should be approached by the secondary preventive measure because of our socio-economic status do not allow us optimistic results from primary preventive measure as far as the problem of CO poisoning is concerned. Author has treated 466 patients during 30 months period by Hyperbaric Oxygenation at Seoul National University Hospital. The results found are as follows. 1. Female has a higher incidence rate than male and the age group between 15-29 years showed highest incidence. 2. The recovery time depends on the time when the patients arrived at hospital. Earlier the arrival time, shorter the recovery time. 3. Some objective signs are representing typical physiological response to tissue hypoxia. 4. Therapeutic effectiveness of Hyperbaric Oxypenation is confirmed by such indices as recovery rate, Admission rate and average stay in hospital. Futher, these results are cocordant with other reports on the clinical value of Hyperbaric Oxygenation in the treatment of CO poisoning.
