The purpose of this study was to examine relationships between chronic diseases, age, and education in Korea. Logistic regression techniques were used to analyze data from the Korean Longitudinal Study of Ageing (KLoSA), which is a nationally representative sample of Koreans aged 45 years and older. The findings show that probability of having chronic diseases increased with age up to about 74; however, it was reduced for respondents aged 74 years or older. Associations between age and chronic diseases were also differential by education. Less educated Koreans tended to have chronic diseases earlier in their lifetime; however, they were likely to have chronic diseases later in life less than more educated counterparts. The findings suggest that individuals with fewer years of education are at an increased risk of developing chronic diseases earlier in their lifetimes, thereby, leading to a higher rate of mortality at younger ages.

희귀질환이란 일반적으로 그 유병율이 인구 일만 명당 5명 이하인 질환을 말한다. 세계에는 약 7,000여종의 희귀질환이 알려져 있고 학술지에 매 주 대략 5종의 새로운 희귀질환이 보고되고 있다. 희귀 의약품(orphan drug)이란 희귀질환치료제 또는 수익성이 없어 개발을 기피하는 일반질환 치료제로서 정부가 지정한 의약품을 말한다. Orphan 의약품의 개발에는 많은 장점이 있다. Orphan 의약품으로 정부의 지정을 받으면 세금감면을 통한 연구비 지원, 임상시험 비용 지원, 신약허가 심사비 면제, 시장독점권 부여 등의 특혜가 주어진다. 희귀질환의 대부분은 단순한 유전적 결함에 의하는 경우가 많아 치료제의 표적발견이 비교적 쉬우므로 개발 성공률이 높고, 임상시험기간이 짧으며, 시판허가를 받을 확률이 높아 연구개발비용이 적게 든다. 그 결과 전세계 orphan 의약품 시장은 최근 매년 6%씩 성장하여 2014년에는 약 1,120억달러의 시장을 형성할 것으로 추정된다. Orphan 의약품 시장은 현재 매년 8.9%씩 성장하고 글로벌 시장의 51%를 점유하는 미국을 중심으로 확장되어 가고 있으며, 총매출액의 64.3%가 유전자재조합의약품에 의한 것으로 알려져 있다. 이러한 의약품시장의 변화와 사회적 요구에 부응하여 한국 또한 희귀질환 치료제 개발의 활성화를 위해 재정적 지원체계를 구축하고, 허가관리를 개선하며, 법률적 제도를 완비하는 과정에 있다. 현재 희귀질환의 치료적 타겟을 찾아 신물질이나 기존의 약물을 발굴하는 과정이 주로 대학이나 연구 중심 병원에서 이루어지고 있다. 제도가 잘 정립되어 있는 미국 시장을 겨낭하여 orphan 의약품 개발을 전략적으로 수행한다면 큰 성공을 거둘 수 있을 것으로 기대된다.

The two main types of inflammatory bowel disease (IBD) are Crohn's disease and ulcerative colitis. Currently, when IBD is suspected, CT enterography is widely used as an initial imaging test because it can evaluate both the bowel wall and the outside of the bowel, helping to differentiate IBD from other diseases. When IBD is suspected, it is necessary to distinguish between Crohn's disease and ulcerative colitis. In most cases this is not difficult; however, in some cases, it is difficult and such cases are called IBD-unclassified. CT findings are often non-specific for ulcerative colitis, making it difficult to differentiate it from other diseases using imaging alone. In contrast, characteristic CT findings for Crohn's disease are often helpful in diagnosis, although diseases, such as tuberculous enteritis can mimic Crohn's disease. Recently, mutations in the gene encoding a prostaglandin transporter called SLCO2A1 have been discovered as the cause of the disease in some patients with multiple ulcers and strictures, similar to Crohn's disease. Therefore, genetic testing is being used to make a differential diagnosis.

Background : Recurrent pneumonia in adults is not uncommon. However, there is no domestic data about recurrent pneumonia in adults. Therefore, we investigated the associated diseases and clinical findings of recurrent pneumonia in adults. Methods : Among 5513 patients who were treated in five teaching hospitals of Hallym medical center?over a 5-year period, we retrospectively reviewed the medical records of the 58 who were compatible with diagnostic criteria of recurrent pneumonia. Results : The number of patients with recurrent pneumonia was 58 (1.05%, 58/5513) during the 5 years. Thirtyseven patients were male and 21 were female. Mean age was 66.4 (${\pm}14.9$) years. Median interval between each pneumonic episode was 18.5 months. Associated diseases were 25 cases of respiratory diseases, 13 of heart diseases, 13 of diabetes mellitus, 7 of lung malignancies, 11 of malignancies other than lung, 7 of neurologic disease, and 8 of miscellaneous diseases. Three cases had no underlying illness. Of the 8 cases with 2 or more times of recurrence, 4 were associated with respiratory diseases, 2 with aspiration pneumonia due to neurologic diseases, 1 with heart disease and 1 with no underlying illness. Recurrent pneumonic episodes affecting the same location were 30 of the total recurrent pneumonic episodes (30/67, 47.8%) and common associated diseases were respiratory diseases including lung malignancies. The etiology of recurrent pneumonia was Streptococcus pneumoniae, methicillinresistant Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, atypical organisms, etc. Conclusion : Recurrent pneumonia in adults had a low incidence rate compared with children, but most cases had associated illness. Respiratory diseases including lung cancer were the most common associated illness of recurrent pneumonia.

The purpose of this study was to examine the periodontal disease awareness and periodontal health status of industrial workers in an attempt to help facilitate their prevention and treatment of periodontal diseases. The findings of the study were as follows: 1. In regard to a knowledge acquisition route on periodontal diseases, the largest number of the industrial workers investigated(36.3%) learned about the diseases from dental hospitals. As to scaling cycle, the younger workers deemed it necessary to get their teeth scaled every six months. In contrary, the older workers considered it advisable to do that about once a year. Age made a statistically significant difference to that (p<.05). 2. As for the state of the periodontal diseases of the workers, the greatest group (26.5%) found themselves to have something between their teeth often. The second most prevalent peridontal disease was gingival bleeding(24.5%), and the third largest group(24.5%) had teeth that were sensitive to cold. The fourth greatest group(15.9%) had the swollen gums from time to time, and the fifth largest group(4.5%) had shaken teeth. 3. Concerning the cause of periodontal diseases, the largest group (48.8%) cited an incorrect toothbrushing. As to the prevention of periodontal diseases, the greatest group(66.8%) viewed the right toothbrushing as the best way for that as well.

The rise in chronic disease not only has a negative effect on people's lives, but it also increases the cost of medical care owing to the increased usage of medical care as health and medical technology improves, life expectancy rises, and rapid population ageing. In such context, this study examined the difference in the disease cost of hypertension according to demographic information and the effect of the initial diagnosis age and treatment period on the cost. This study used the Korean Health Panel Survey from 2010 to 2017, and selected subjects based on health insurance beneficiaries between the ages of 30 and under 80. With the selected data, the direct and indirect costs of disease loss were calculated according to the cost of illness approach, and we constructed a disease-loss ratio cohort considering the age of diagnosis and time of treatment for hypertension. From the results of the study, the annual cost of disease loss for hypertensive patients differed by gender by 110,107 won, and it was found that the cost increased by 1.8 times as the treatment time increased. In addition, when comparing disease loss ratios between the same age groups, it was found that the disease loss ratios between those in their 60s and 70s were affected by treatment time. This study confirmed that hypertension significantly affects the cost of the disease, and not only requires early diagnosis and management, but also preventive efforts to lower the incidence of hypertensive disease must be strengthened.

Background: In order to emphasize the importance of clinical dental hygienists-led dental hygiene management processes for those with systemic diseases, we tried to identify systemic diseases affecting dental implants based on clinical data. Methods: In order to identify systemic diseases affecting dental implants, literature review was conducted from March 1 to May 31, 2023, and the search period was for research papers published in domestic and foreign academic journals from January 2000 to December 2020. Domestic databases used for search use RISS, Nuri Media(DBpia), and Korea Academic Information (http://www.papersearch.net ; KISS), while overseas databases searched Pubmed for dental implant failures, implants, systemic diseases, and Dental implant and system disease. Results: The cumulative survival rate of implants averaged 94.3 percent and the failure rate was 5.7 percent. Clinical analysis of systemic diseases related to implants accounted for the highest frequency with 13 (100.0%), followed by 8 (61.5%) studies on high blood pressure and smoking, 7 (53.8%) cardiovascular diseases, and 5 (38.5%). In addition, liver disease, thyroid abnormalities, blood abnormalities, organ transplants and infectious diseases were confirmed. Conclusion: Since unregulated systemic diseases are a risk factor for implant failure, clinical dental hygienists should continue to maintain healthy oral conditions by sharing information with patients during periodic preventive dental hygiene management processes such as dental hygiene assessment.
