The aim of this study was to recommend the optimal age for prevention of periodontal disease and to investigate the trend of treatment modality according to different period. From the chart recordings of the patients who had been treated periodontally from Jan. 1981 to Dec. 1995 in the dept .of periodontics, Chosun University Dental Hospital, those of the periodontally treated patients on more than 4 sixtants were selected for the present study. The distribution of the patients was counted according to the age group and the gender. And they were divided into 3 groups(group 1: 1987-1958, group 2: 1985-1990, group 3: 1991-1995) by 5 year interval according to the treated year. The periodontal treatment modalities were classified into non-surgical therapy, pocket elimination surgery, regenerative periodontal surgery, mucoginigival surgery, clinical crown lengthening, and others. The results were as follows; 1.In the distribution of the periodontally treated patients according to the age group, 40's age group was the highest, and 30's, 40's, and 50's age groups occupied more than two thirds(73%). 2.The sexual distribution of the periodontally treated patients showed that males(53.4%) were a little more than females(46.6%). Within 20's group female was higher, but within 40's male was higher. 3.Regardless of the age group and the gender, pocket elimination surgery was the most frequent treatment modality. 4.In group 1 and 2(1987-1990) the main treatment modality was pocket elimination surgery and non-surgical therapy, but in group 3(1991-1995) it was regenerative periodontal surgery and pocket elimination surgery. The above results suggest that the prevention of periodontal disease should be initiated from early twenties, and the most frequent treatment modality may be closely related with development of new material and method.

Purpose: This study was performed to evaluate the outcomes of the home care nursing program conducted jointly by thirty two catholic churches and C hospital in Seoul. Method: The subjects included 173 patients who registered for the program during a 4 month-period from November 1, 2004 to February 28, 2005 and received home care services for more than 4 times and 32 professional nurses participating in the program. Using the concept of medical outcome study (MOS), the structure, process, outcome elements were analyzed. Result: 1) A Catholic homecare nursing center and nurses of the C hospital played a central role in providing nursing care, and each church operated its own vehicle from its own office. Home care nurse's job satisfaction was 2.8 out of total score of 4. The major illness was cerebrovascular disease including stroke followed by skeletomuscular disease including degenerative arthritis cancer, and diabetes. Among reasons for accessing the home care nursing program, hypertension management was most prevalent. More than half of the registration was done through catholic churches. Most people who referred the patient to the program was through the church. Most patients received home care nursing 1-2 times a week for 30 to 60 minutes in average and the most frequent type of service provided was basic nursing. 3) The most frequent reason for terminating home care services was death. The change in PPS(Palliative Performance Scale) level from the time of registration and after 4 visits was the same in 45%, decreased in 30%, and improved in 25%. Patient satisfaction was very high, showing 3.4 out of total score of 4. Conclusion: These results proved that the home care nursing program was highly appreciated by subjects and nurses were providing professional care. Thus the two parties involved in the program were actively supporting the program to fulfill their mission. However, several areas needed to be improved such as relating with local community, relating with family doctor, and issue of improving the working conditions for home care nurses.

Background and Purpose: Stroke in young adults is relatively uncommon. Only 3.7-14.4% of all strokes occur in patients aged 15-45 years. Stroke in young adults has more various and diverse possible causes than stroke in the elderly. We studied to gain further insight into both pathogenic and etiologic determinants in young adults with stroke. Methods : We retrospectively reviewed the medical records of 230 young patients aged 15-45 years who were admitted to the 2nd internal medicine department of Kyung Hee Oriental Medical Center with a diagnosis of stroke between May 1995 and May 1999. We analysed clinical features and diagnostic tests, such as brain imaging, cerebral angiography, echocardiography, 24 hours holter monitoring and other laboratory tests. Results : 1. Of 230 young patients with stroke aged 15-45 years(176 males(76.5%) and 54 females(23.5%)), 140 patients(60.9%) showed ischemic stroke and 90 patients(39.1 %) showed hemorragic stroke. 2. The most prevalent age group was from 40 to 45 years with 142 patients(61.7%) 3. The most frequent site of 140 ischemic stroke was MCA territory in 93 cases(66.4%) and Multiple, VA territory, PCA territory, ACA territory in order of frequency. 4. The most frequent site of 90 hemorrhagic stroke was basal galglia hemorrhage 57 cases(63.3%) and subcortical 13 cases(14.5%), pons, thalmus, subarachnoid, cerebellum in order of frequency. 5. The causes of hemorrhagic stroke were hypertension 49 cases(54.5%), arteriovenous malformation 7 cases(7.8%), ruptured aneurysm 4 cases(4.5%), angioma 3 cases(3.3%). 6. The risk factors of ischemic stroke were smoking, alcohol drinking, hyperlipidemia, hypertension, obesity, heart disease, history of CVA, diabetes mellitus, in order of frequency. 7. The comparison of risk factors between ischemic and hemorrhagic stroke: hypertension was prevalent in hemorrhagic stroke, heart disease and history of CVA were prevalent in ischemic stroke. Conclusions: From the above results, we found that stroke in young adults had various possible causes. Young adults with stroke deserve an extensive but tailored evaluation which include angiography and echocardiography for diagnosis.

Reexpansion of the lung is the most desirable method of filling the pleural space whether it`s contents may be, and closed thoracotomy connected to a water-seal drainage remains the basic therapeutic modality in the treatment of the problems of the pleural space. We usually used rubber mushroom tubes, size No. from 16 to 34 Fr., and performed closed thoracotomy after preliminary thoracentesis to determine the exact depending position. Author reviewed 576 cases of closed thoracotomy which were performed in the Department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital, since Jan., 1980 to June, 1984. The results were as follows: 1. The age distribution was 10 days to 76 years old and mean age of the patients was 36.6 year, and the most prevalent age group was twenties, and sex predisposition was male dominant, 86.9%. 2. The most common etiologic disease group was pneumothorax and the most common etiologic disease was traumatic hemothorax. 3. Sites of tubing were predominantly at posterior axillary line, 7th intercostal space and midclavicular line, 2nd intercostal space even though frequent presence of free pleural space. The two sides, right and left difference of occurrence rate was more frequent at right side, 51.2%. 4. Usually the durations of tubing was less than 10 days, 52.6%, and the number of tubes used to the same patient concomitantly was one, 73.9%, and the time of tubing to the same patient was 1st, 83.6%. 5. The common symptom and sign were dyspnea, 50.0%, chest pain, 30.7%, cough, 10.7%, fever, 6.5%. Especially, fever and cough was the most common symptom and sign in pyogenic empyema, 59.3%. 6. The common etiologic lesions of pneumothorax were blebs and bullae, 73.3%, and of pyogenic empyema was pneumonia, 69.0%. 7. The complication rate of closed thoracotomy was 26.0%. Among these complications, infection was 44.7%, and intercostal neuralgia was 25.3%. 8. 70.9% of all patients recovered with only closed thoracotomy and the rest of patient needed additional some necessary managements such as open thoracotomy [Blebectomy, Resection, Pleurodesis, Decortication, Bleeding control], open drainage, thoracoplasty and so on to have successful results.

Objective: This study was performed to research Korean medical treatment methods for hyperthyroidism by summarizing domestic clinical studies. Methods: The study was based on 14 papers published in Korea since 2000, on Korean medicine treatments for hyperthyroidism. Papers were searched on four domestic electronic databases. Results: 1. This paper analyzed 14 studies on the subject of clinical research on hyperthyroidism in Korea. 12 of them reported cases while two of them reported on clinical research. 2. The average age of the subjects was 39 years, 71.3% of women, 20-60 years of age accounted for 92%, and the average duration of disease was 22 months. 3. Of the 115 subjects, 102 had experienced Western medical treatment. So most of them chose Western medical treatment as the first treatment method, of which 24 experienced side effects. 4. Eumhuhwadong (陰虛火動) and Gieumyanghu (氣陰兩虛) appeared 3 times respectively. 5. The Korean herbal medicine, Ahnjeonbaekho-tang was the most frequent herbal medicine used to treat hyperthyroidism, with the next most frequent being Yanggyuksanhwa-tang. 6. The study, which was performed using herbal medicine alone, showed a marked improvement in clinical symptoms and thyroid function test, compared with administration of antithyroid drugs and herbal medicines. Conclusions: Large-scale studies and randomized controlled trials will be needed to evaluate the validity of Korean medical treatment for hyperthyroidism.

Background: Antibiotic resistance has been becoming serious challenge to human beings. Overuse of antibiotics, especially, for infants is concerned, but studies are very few for the prescribing pattern of antibiotic use for infants. This study analyzes prescribing patterns of antibiotics in outpatients of preschool children with acute respiratory tract infections in South Korea. Methods: Data are used from 2011 Health Insurance Review & Assessment Services-pediatric patients sample. Inclusion criteria is outpatient children (0 to 5 years) with top five frequent diseases. Prescription rates are analyzed by types of disease, provider, specialty, region, and ages. Binary or multinomial logit models are used to analyze determinants of providers' prescription pattern. Results: The main findings are as follows. First, distributions of prescription rates are shown as L-shape or M-shape depending on the types of disease. Second, the prescription variation is so large among providers, where providers are polarized as a group with low prescription rates and the other group with high prescription rates, though the shapes are shown diversified across types of disease. Third, prescription rates appear to be lower in pediatrics and higher in ENT (ear-nose-throat). Fourth, broad spectrum antibiotics are widely used among children. Finally, the logit analysis shows similar results with descriptive statistics, but partly different results across types of disease. Conclusion: Antibiotics for respiratory tract infections of infants are used excessively with a large variation among providers, and especially broad spectrum antibiotics are used. The prescription guideline for antibiotics should be provided for each specific disease to reduce antibiotic resistance in the future.

The sick sinus syndrome refers to a combination of symptoms (dizziness, confusion, fatigue, syncope, and congestive heart failure) caused by sinus node dysfunction and marked sinus bradycardia, sinoarterial block, or sinus arrest. 'Abdominal pulsation' means a disagreeable symptom that is defined as sensation of beating at the abdomen. We experienced a 84 year-old female patient who had dizziness, fatigue, abdominal pulsation and frequent voiding. These symptoms were related to previous episodes and presumed sick sinus syndrome by symptoms, ECGs and 24 hrs of holter monitoring. In the point of Differentiation of Syndrome (辨證), this patient was diagnosed as 'Water retention(水氣)' and was administered with Yeonggyechulgam-tang(岺桂朮甘湯). After the treatment, abdominal pulsation (frequency) and dizziness (VAS) were improved. Futhermore, the interval of voiding was longer and each volume of urination increased.

Objective : Thoracic ossification of the ligamentum flavum (OLF) is a relatively rare disease. Because of ambiguous clinical symptom, it is difficult for early diagnosis of OLF and subsequent treatment can be delayed or missed. Therefore, the purpose of this study is to comprehensively assess the prevalence and distribution of thoracic OLF by magnetic resonance imaging (MRI) and coexisting spinal disease in Korean patients with back pain or leg pain. Methods : The sample included 2134 Korean patients who underwent MRI evaluation for back pain. The prevalence and distribution of thoracic OLF were assessed using lumbar MRI with whole spine sagittal images. Additionally, we examined the presence of coexisting lumbar and cervical diseases. The presence of thoracic OLF as well as clinical parameters such as age, sex, and surgery were retrospectively reviewed. Results : The prevalence of thoracic OLF in total patients was 16.9% (360/2134). The prevalence tended to increase with aging and was higher in women than in men. The lower thoracic segment of T10-11 was the most frequently affected segment. Of the 360 patients with OLF, 31.9% had coexisting herniated thoracic discs at the same level. Approximately 74% of the patients with OLF had coexisting lumbar and cervical disease. Nine (2.5%) of 360 OLF patients underwent surgery for thoracic lesion. Conclusion : The prevalenceof thoracic OLF was relatively higher than those of previous reports. And coexisting lumbar and cervical disease were very frequent. Therefore, we should check coexisting spinal diseases and the exact diagnostic localization of ossification besides lumbar disease.

Behçet's disease is a chronic systemic inflammatory disorder with an unknown etiology. It affects many organs and is characterized by recurrent attacks. Pulmonary artery aneurysms occur more frequent in males, and it is one of the rare pulmonary complications of Behçet's disease. It has a poor prognosis, and is also one of the leading causes of death from Behçet's disease. Here we report a case of suspected Behçet's disease diagnosed by a manifestation of a pulmonary artery aneurysm in a 37-year-old woman.
