  • Acute otitis media and acute sinusitis are some of the most common antibiotic-prescribed diseases in childhood. Usually, with an accurate diagnosis, a 10-14 day course of antibiotics is recommended to cover common causative agents, including pneumococci. Establishment of management guidelines for these infectious diseases based on further study of the epidemiologic profile, antibiotic resistance, and clinical circumstances in Korea is needed.

  • This epidemiologic study was carried out to investigate cauuse and magnitude of food-poisoning like epidemic occurred among inhabitants of a village who have eaten dead cow's meat near Kyongju in February of 1994, around lunar new year, The investigation consisted of interview survey on all inhabitants of 77 households (111 males and 119 females) and their visitors (40 males and 35 females), skin test with anthraxinum (Russian product), study on clinical characteristics for the patients hospitalized, and microbiologic examination on microbes isolated from cow's meat, patient and soils of dead cow's barn. The results obtained are as followings; 1. The proportion of the inhabitants who ingested the dead cow's meat was 36.4%. The incidence rate of the disease was 65.1% for males, 41.7% for females and the cases were distributed evenly for all age groups. The group ingested raw meat showed higher incidence than the group ingested cooked meat. There was no case among people who did not eat the meat. 2. The most clinical symptoms were significantly more frequent among cases than non-cases : sore throat (57%), nausea (51%), fever (47%), indigestion (43%), cough (41%), anorexia (41%), abdominal distention (41%), and abdominal pain (39%) were the major symptoms among cases. 3. Among 29 cases hospitalized out of total 61 cases, three patients, all old and feeble persons, deceased from the disease resulting in 4.9% fatality rate among total patient and 10.3% among hospitalized. Septicemia and meningitis were the causes of the deaths. 4. Three strains isolated from patients, and three strains from dead cow's meat and soil revealed typical microbiologic characteristics of Bacillus Anthracis, which also proved to be fatal to experimentally infected mice.

  • 목 적 : 본 연구는 소아에서 보카바이러스와 연관된 하기도 감염증의 역학적인 특성에 대해 알아보고자 하였다. 방 법: 2000년 3월부터 2005년 9월까지 서울대학교 병원과 분당 서울대학교병원에 하기도 감염증으로 입원한 658명의 소아에게서 비인두 흡입 검체를 채취하였다. 다중 역전사 중합효소 연쇄 반응을 이용하여 11종의 바이러스를 조사하였고, 의무기록을 후향적으로 분석하였다. 결 과:전체 호흡기바이러스는 658명의 환아 중 325명(49.4%)에서 검출되었다. 보카바이러스는 62명(9.4%)에서 검출되었으며, 3개월 이상 5세 미만에서 많았다. 보카바이러스가 중복감염이 확인된 것은 37.1%로, 전체 바이러스 양성 환자들의 중복감염률(12.3%)보다 의미 있게 높은 것으로 확인되었다(P =0.000). 또한 늦은 봄부터 이른 여름인 5월부터 7월에 많이 검출되었다. 결 론 : 보카바이러스는 국내에서 소아의 하기도 감염증에서 유병률이 높았고, 특히 늦은 봄부터 초여름에 유행하였다.

  • 측두하악관절장애에 관한 역학연구는 주로 1970년대 초 스칸디나비아국가에서 국민을 대상으로 무작위 추출법에 의한 악관절 및 저작계기능에 관한 역학조사로 시작되었으며 국내에서도 1970년대 이후 측두하악관절장애의 유병률에 대해 많은 역학연구가 보고되었다. 하지만 성, 병력, 주소, 진단에 따른 각각의 증상과 징후들을 평가한 연구는 외국에 비해서 많이 부족한 실정이다. 측두하악관절장애에 대한 증상과 진단에 관한 총괄적 연구조사는 오래전에 이루어진 것이 대부분이기 때문에 본 연구를 통해서 측두하악관절장애를 가진 환자들의 성, 병력, 주소, 진단에 따른 증상들을 총괄적으로 조사하여 향후 점증하는 측두하악관절장애환자의 진단과 치료에 도움이 되는 기초자료를 확보하고자 하였다. 본 연구결과를 보면 우선 연령의 경우 전체 내원 환자 6500명의 평균나이는 34.06세로 남자는 33.15세, 여자는 34.62세였으며 진단그룹별로 연령차이가 있었다. 의뢰 환자는 대체로 치과의사가 의뢰한 환자가 많았으며(80.07%), 의뢰한 환자 진단군은 관절성장애, 근육성장애, 연조직질환 순이었다. 전체 내원 환자 중 63%가 안면통증으로 내원하였으며, 발생부위에 대한 비교에서 좌우 유의한 차이를 볼 수 없었다. 또한 통증 발생은 6개월 미만에서는 주로 남성이, 6개월 이상인 경우는 여성의 비율이 상대적으로 높음을 알 수 있었다. 관절잡음의 경우 병력 환자는 3445명(53.15%)였으며, 발병시기에는 성차가 없었다. 관절잡음의 발생부위는 좌우 양측간에 차이가 없었으며 주로 clicking sound가 많음을 알 수 있었다. 이갈이는 주로 남자에서, 이악물기는 여자에서 나타났었다.

  • 1. Objective This study aimed to find out the epidemiologic characteristics of constitutional disease syndromes at a hospital of Oriental medicine in Seoul. 2. Methods The medical records of 1354 subjects who have received prescriptions and diagnosis of Sasang constitution from January 2008 to December 2009 at a hospital of Oriental medicine were reviewed. General factors and the frequency of the prescriptions according to Sasang constitution were compared and analyzed. 3. Results 1) Among the 1354 subjects, 562(41.5%) persons were males and 792(58.5%) females. 614(45.3%) persons were Soeumin, 369(27.3%) Soyangin, 364(26.9%) Taeumin, and 7(0.5%) Taeyangin. 2) The frequencies of the prescriptions of 14 constitutional disease syndromes were compared. Taeum Syndrome, Esophagus Cold Syndrome and Yin Deficiency Tidal fever Syndrome show the high frequencies among 14 disease syndromes. Chest Heat Syndrome, Deficiency of Yin and Blood syndrome and Soeum Syndrome show the low frequencies among 14 disease syndromes. Interior disease(63.4%) was higher than exterior disease(36.6%) and mild disease(61.8%) was higher than severe disease(38.2%). 3) Among all constitutional prescriptions, Jowyiseungchung-tang was the most common and next rankings were Gupoong-tang and Dokhwaljihwang-tang in turns. 4. Conclusions From all these considerations, it would seem that Taeum Syndrome in Soeumin, Esophagus Cold Syndrome in Taeumin and Yin Deficiency Tidal fever Syndrome in Soyangin show the high frequencies in a hospital of Oriental medicine in Seoul. Large-scale epidemiologic study in Sasang constitutional medicine may be needed on various ways and places.

  • Objectives: This study was conducted in order to improve the current understanding of rare earths(RE) and to provide supporting data for establishing occupational health policies by reviewing the toxicological data and issues caused by the use of RE compounds in various fields. Methods: To evaluate the potential toxicity of RE from the viewpoint of occupational health, we summarized extensive reviews of relevant articles in the toxicology(animals and cells), occupational health and safety, and epidemiologic literature. Results: Although occupational RE exposure occurs extensively from ore mining and refining to end users in various industrial applications, epidemiologic study has not been performed among workers up to now. Bioaccumulation and adverse effects of RE have also been mentioned in ore mining regions and nearby residences, but safety standards for each process are insufficient. Moreover, because new commercial recycling technology will soon be applied to various industries, regulation and policies are needed for preventing abuse of recycling. In the results of animal toxicity for a few REs(mostly cerium, lanthanum, and gadolinium), toxicities of liver, lung, blood, and the nervous system were identified due to oxidative stress, but study of long-term RE exposure is required. Understanding the dual effect for RE and discovery of biomarkers pose a scientific challenge in further mechanism studies. Conclusions: In the future, additional hazard evaluation based on animal experiments is required, alongside continuous research for developing analytical methods and discovering biomarkers. Finally, RE occupational health and safety management needs to be integrated into the sustainable use of these materials.

  • Purpose: This was a nationwide population-based study conducted to investigate the epidemiology, treatment, disease outcomes, and associated factors of childhood intussusception in South Korea. Methods: Data from the Korean National Health Insurance Service database on all patients <18 years old diagnosed with intussusception from 2007 to 2017 were analyzed. Results: A total of 34,688 cases were identified among 30,444 patients. The overall incidence was 28.3/100,000 person-years with a male predominance. Most cases (83.1%) occurred in children <3 years old, with an annual incidence of 195.2, 200.1, and 118.6 cases per 100,000 children in their first, second, and third year of life, respectively. The median age at the first occurrence was 18.7 months, and it was higher in boys than in girls. The post-discharge recurrence rate was 10.6% (3,226/30,444) and the in-hospital recurrence rate was 6.1% (1,842/30,444). The total recurrence rate (post-discharge recurrence and/or in-hospital recurrence) was 15.0% (4,580/30,444). Enema reduction was successful in 90.0% of cases. Enema reduction was more successful in girls than in boys. A total of 3,296 (10.8%) patients underwent 3,481 surgeries, including 735 (21.1%) laparoscopic surgeries. Post-discharge recurrence and surgery were significantly affected by age, sex, and hospital type. Mortality was noted in nine cases (0.03%). Conclusion: Our study provides accurate epidemiologic data on the treatment and outcomes of intussusception through complete enumeration during an 11-year-period.
