A modern development of ambulatory ECG monitoring gave great advances in the diagnosis and evaluation of various cardiac conditions. Fifteen cases of ischemic heart disease, 11 cases of nonischemic heart disease, 5 cases of noncardiac disease and 9 cases of normal healthy subjects were studied from January 1980 to July 1981 in national Medical Center, with the following results: 1) The heart rate was decreased during night time, with less decreasing tendency in patients with ischemic heart disease. 2) Among 30 cases, including 12 patients with ischemic heart disease, who didn't show arrhythmia on routine 12 lead ECG, 12 cases, including 6 patients with ischemic heart disease, showed arrhythmia on Holter monitoring. 3) Among 5 cases with ischemic heart disease who showed premature ventricular contraction on day time monitoring, 2 cases didn't show premature ventricular contraction on nigh time monitoring. 4) The S-T segment and T wave were changed during night time in 2 cases with ischemic heart disease and in 2 normal subjects. From these results, we could assert that Holter monioring or ambulatory ECG tracing would be a good method for diagnosis and evaluation of ischemic heart disease, and other cardiac conditions. Several another studies with this equipment have to be performed and would give more distinctive outcomes.

OBJECTIVES: This study aimed to evaluate the relationship between oral health professionals' knowledge, attitude, and practice with regard to infectious waste management and to identify related factors influencing it. METHODS: The study comprised of 219 oral health professionals from select dental clinics and public health centers recruited between August 25, 2016 and September 5, 2016, who agreed to participate in the study with full understanding of the study objectives. A self-reported questionnaire was administered, which consisted of 22 items on knowledge of infectious waste management, 9 items on attitude, and 16 items on practice. Data were analyzed using Pearson's correlation coefficient and stepwise multiple regression analyses. RESULTS: The age, knowledge, and clinical attitude of oral health professionals significantly correlated with waste management practice. Specifically, infectious waste management practice improved with increasing age, a greater level of knowledge, and a more positive clinical attitude. Additionally, the standardized regression coefficient demonstrated that, of these three factors, clinical attitude more strongly correlated with effective waste management practice, followed by age and level of knowledge. CONCLUSIONS: These results indicated that oral health professionals had a low level of knowledge regarding infectious waste management, and a more positive clinical attitude resulted in better practices. Therefore, the development of detailed and active education guidelines and strategies are needed to enhance the attitude, knowledge, and practice of oral health professionals with regard to infectious waste management.

The expression of c-fos and c-jun in the brain of the rat after capsaicin treatment was investigated by in situ hybridization, dot blot hybridization and immunocytochemical methods. Adult male Sprague-Dawley rats[200g] were used for this study. The first set of rats received a single subcutaneous injection of capsaicin[50mg/Kg] dissolved in 10% Tween-80 and 10% ethanol in saline. The rats were decapitated 1, 3, 5, 10, 24, 72 hours and 1 week after capsaicin treatment. The control set of rats were treated with saline instead of capsaicin. In situ hybridization and dot blot hybridization were carried out. O1igonucleotide probe complimentary to c-fos mRNA sequences were used for this study and labeling of oligonucleotides was accomplished using the DNA tailing kit. The expression of c-fos mRNA on the nucleus of neurons in in situ hybridization was observed throughout the brain, and was especially abundant in the olfactory cortex, nucleus of diagonal band of Broca, habenular nuclei, periaqueductal gray, parabrachial nucleus, entopeduncular nucleus, ventral posterolateral nucleus of the thalamus and cerebellum. Compared to the control rats, c-fos mRNA were increased 24 hours after capsaicin injection and gradually decreased after 72 hours, returning to the normal control level 1 week after capsaicin injection. c-fos mRNA was detected only 1 week after capsaicin injection in the various areas of the brain. The fos protein-like immunoreactivity was initially somewhat decreased at 24 hours, but increased at 72 hours and reactions was maximally observed at 1 week after capsaicin treatment. But Jun protein immunoreactivity was not increased, on the contrary, it was even decreased both in numbers of reactive cells and immunoreactivity 1 week after capsaicin injection. From the above results, c-fos gene expression was pronounced in the nucleus concerned with pain, olfaction and taste such as VPL nucleus of the thalamus, olfactory cortex and parabrachial nucleus, in the limbic system concerned with stress and emotion such as nucleus of diagonal band of Broca, periaqueductal gray and habenular nucleus, in the structure concerned with somatic motor function such as entopeduncular nucleus and cerebellum. Also, the c-fos gene was activated by the capsaicin early in the course of effects, then the fos protein increased as a results of c-fos activation. On the other hand, c-jun did not respond to capsaicin treatment early in the course, but Jun protein decreased late in the course of capsaicin effects.

Purpose: To report a case of successful treatment of bilateral infectious keratitis combined with endophthalmitis caused by Pseudomonas aeruginosa in an immunocompromised patient.Case summary: A 66-year-old male with colon cancer and lung metastasis was referred to our clinic with ocular pain and reduced visual acuity in both eyes for 3 days. Visual acuity was “light perception” in both eyes at the first visit. On slit lamp examination, he presented with corneal central necrosis with mucopurulent discharge and anterior chamber hypopyon in both eyes. The left eye especially had vitreous haziness using a B-scan. Pseudomonas aeruginosa was detected in the corneal scrape culture and percutaneous transhepatic biliary drainage culture. After administration of topical eye drops, intravitreal injection, and systemic antibiotics, visual acuity improved from “light perception” to 20/63 in the right eye and to 20/125 in the left eye. Conclusions Although bilateral corneal ulcers combined with endophthalmitis induced by Pseudomonas aeruginosa are rare it can occur in immunocompromised patients. In the case of corneal ulcers combined with endophthalmitis, thorough ocular examinations and active treatments with intravitreal injections and systemic administration of antibiotics can help to recover vision.

Objectives: This study aimed to investigate the association between food insecurity and periodontitis in Korean adults. Methods: The data used for analysis were obtained from the 7th Korean National Health and Nutrition Examination Survey (2016-2018). Data were analyzed using chi-square test. Additionally, multiple logistic regression analysis was performed to assess the association between food insecurity and periodontitis. Statistical significance level was set at <0.05. Results: In models corrected for social, economic, medical, and health behavioral factors, logistic regression analysis for food anxiety and periodontitis showed a significant correlation with F4 (odds ratio [OR]: 2.22, 95% confidence interval [CI]: 1.03-4.79). Conclusions There was a significant association between food insecurity and periodontitis in Korean adults. These results show that food insecurity is associated with periodontitis, and that food stability is an essential factor in improving or managing periodontitis.

Objectives: The present study examined trends in search keywords related to the oral health of infants and pregnant women using “social media cafés” on the Korean portal site, Naver. Methods: We obtained data from January 2015 to December 2017, collected by searching for common terms related to oral health, such as “dental caries”, “oral health”, “scaling”, “tooth brushing”, and “oral examination”. Search results for these terms were organized by frequency and visualized by increase in the font size with increasing frequency. Results: The ranking of keywords on Naver cafés for pregnant women and women with infants was as follows (in descending order): “oral examination”, “tooth filling”, and “tooth brushing”. The “oral health” network was linked to “dental caries”, “oral health education”, and “tooth brushing”. In addition, the analysis of trends of keyword frequencies according to time periods showed that “dental caries” and “oral examination” were of highest interest to the café users. Conclusions We found a high interest in keywords related to preventive measures for the oral health of infants and children, but there was a lack of awareness regarding the oral health of pregnant women. These findings suggest that prevention in infants and pregnant women is necessary, and that public awareness regarding education about oral healthcare needs to be raised.

Objectives: This study investigated the contents and structure of chapters on oral health to determine the quality of middle and high school health textbooks. We also comparatively analyzed the learning objectives of these textbooks according to the oral health curriculum proposed by the Virginia Department of Health (VDH) and South Carolina Department of Education (SCDE). Methods: The structure and educational contents of eight health textbooks (middle school, five; high school, three) published in 2019 were analyzed methodologically. We compared the structure and contents between the middle and high school curricula. We also carried out comparisons among five publishing companies. Results: Of the eight health textbooks examined, five (middle school, four; high school, one) had chapters on oral health. In terms of structure, textbooks published by company A had the lowest percentage (0.96%) of pages on oral health. The highest percentage (1.50%) was found in a middle school textbook published by company D. We noted subject-level differences between the curriculum proposed by VDH, SCDE, and that of the published textbooks. There were more keywords pertaining to the definition and development of oral diseases than those for its prevention and management. Conclusions It is critically important to impart oral health education to middle and high school students for self-management of oral health during adolescence, a period characterized by both rapid physical and psychological development. Therefore, we recommend that all health textbooks should include chapters on oral health. Further, in the health textbooks that already include oral health information, we propose that the revised curricula should include key learning objectives.

Spark’s nevus is a compound word composed of Spitz nevus and Clark’s nevus. It is one of the combined melanocytic nevi which is more common in female and usually presents as a sharp circumscribed hyperpigmented macule on the lower extremities. On histopathologic findings, both cytologic features of Spitz nevus characterized as large spindle or epithelioid melanocytes containing large nuclei with abundant cytoplasm, and architecture of Clark’s nevus characterized as elongation of rete ridges, bridging of the nests, concentric and lamellar fibrosis can be seen. A 24-year-old female presented with an asymptomatic, solitary, dark-brown-colored papule surrounded by brownish patch that looked similar to dysplastic nevus or malignant melanoma on the buttock. On dermoscopic examination, it showed brown-to-black globules, diffuse homogenous pigmentation with blue-white structures, and a surrounding brownish reticular pattern that faded away. On histopathologic findings, overall asymmetrical structure, epithelioid large melanocytes containing large nuclei with abundant cytoplasm, and Kamino body were seen in the central portion. Also, lentiginous hyperplasia, bridging of the nests composed of melanocytes containing foamy cytoplasm, concentric and lamellar fibrosis along with the elongation of rete ridge, and perivascular lymphocytic infiltration were seen in the peripheral portion. The diagnosis of Spark’s nevus was made. Following its definition, this combined nevus is diagnosed histopathologically, but the clinicodermoscopic features have not been well described. Herein, we report a case of Spark’s nevus in which dermoscopy was helpful for differentiating it from malignant melanoma.

BACKGROUND: Arterial hypoxemia has been noted in patients with liver cirrhosis because of bronchial vessel dilatation. Cabenes et al. reported that bronchial hyperresponsiveness to the metacholine inhalation was observed in patients of left side heart failure, he suggested that one of the mechanism was bronchial vessel dilatation. We hypothesized that patients of liver cirrhosis might have bronchial hyperresponsiveness to metacholine inhalation due to portal hypertension. We evaluate the relationship between bronchial responsiveness and severity of liver cirrhosirs, severity of portal hypertension. METHODS: In the 22 patients of the liver cirrhosis with clinical portal hypertension metacholine provocation test was done and determined PC20 FEV1. We classified lifter cirrhosis according to Pugh- Child classification Esophagogastroscopies were performed for the evaluation of the relationship between bronchial hyperresponsiveness and severity of esophageal varix. RESULTS: In the 22 cases of the liver cirrhosis with clinical portal hypertension. The causes of liver cirrhosis, alcoholic hepatitis was 9 cases. hepatitis B virus was 12 cases, hepatitis C virus was 1 case. and 151 cases (68.18%) of total 22 cases were positive in metacholine provocation test. In positive cases There was no significant relationship between PC20FEV1 and severity of liver cirrhosis which were classified by Pugh-Child classification or severity of esophageal varix(p<0.05). CONCLUSION: we observed that bronchial responsiveness to metacholine increased in the patients of liver cirrhosis and there was no significant relationship between the severity of liver cirrhosis and the severity of esophageal varix.

Targetoid hemosiderotic nevus (THN) is a rare variant of melanocytic nevus, characterized by a sudden development of a targetoid ecchymotic halo around a pre-existing nevus. THN clinically raises concern for malignant transformation due to its abrupt change in color and size. THN should be distinguished from other diseases showing a peripheral halo, including targetoid hemosiderotic hemangioma, halo nevus, and Meyerson nevus. Dermoscopy can help clinicians to differentiate THN from these diseases. The typical dermoscopic features of THN are known to be divided into two distinctive areas: the central melanocytic area and the peripheral ecchymotic area. In our case, dermoscopy revealed a novel bull’s eye pattern composed of a central area with characteristic features of benign melanocytic nevus, an intermediated white circular ring, and a peripheral milky red area. When a sudden change occurs in a pre-existing nodule showing targetoid features, dermoscopy should be considered before conducting a biopsy or surgical intervention.
