Treatment methods of mandibular condylar fracture were conservative and surgical method. Surgical method of mandibular high condylar fracture was very difficult because approach and internal fixation of small size fracture fragment were difficult. So there is a tendency to select conservative method over surgical method for guiding a stable occlusion and avoiding TMJ disorder and growth disturbance, minimizing pain and deviation during function. But, in case of mandibular high condylar fracture patient who has no biting teeth on posterior teeth area, guiding a stable occlusion and conservative functional treatment were very difficult. In this case, patient was 62years old male. He had fracture of mandibular symphysis, right mandibular body, left mandibular high condyle. We treated the patient for mandibular symphysis and right mandibular body fracture area with surgical method. But left mandibular high condylar fracture area was difficult to treat with surgical method. So we selected a conservative functional method on left mandibular high condylar fracture area. We intended recovery of vertical dimension and stable occlusion with implantation of immediate provisional implant on maxillar and mandibular posterior teeth area, and temporary crown. And then patient did mandibular functional movement and his mandibular function was recoverd.

This study was performed to evaluate the semiquantitative food frequency questionnaire used to obtain information about. dietary patterns of adults in a rural county, Yang-pyeung Gun. The study population was 1311 adults aged 17~85 years. And well-trained interviewers interviewed subjects in 1990, 1992, 1993. The results are as follows. 1) Nutrients intake calculated from each questionnaire showed significant difference, because the number of question was not same(fifty questions in 1990, eighty questions in 1992, 1993). 2) Estimated nutrients intake from separate food items was significantly different when food items are combined in one question. 3) The agreement of nutrients intake level except vit C were high when the subjects are cross-classified by their ranks on the nutrients intake level from items in both questionnaires and on the nutrient intake level from items in each questionnaire. 4) And analysing this study data by multiple stepwise regression, we selected twenty seven food items whic could explained over 85% of inter-individual variation of nutrients(energy, carbohydrate, fat, protein, vit A, vit B1, vit B2, vit C, Ca). From above results, we suggested that it is neccessary to standardize questionnaire and perform validity studies.

PURPOSE: The study was done to examine the effects of cognition-behavior integrated breast cancer prevention education, in which a breast model with interchangeable nodules was utilized, on the self-competency of nursing students in performing breast cancer education. METHODS: A nonequivalent control group non-synchronized design was used. A traditional lecture intervention was provided for 49 3rd year college of nursing students (control group) while the integrated breast cancer prevention education was given to 47 3rd year students in the same college one year later (experimental group). The integrated breast cancer prevention education was developed by the research team to strengthen the competency of cognitive and behavioral components in education on breast cancer. RESULTS: Effects of the intervention were found to be significant through all study variables: knowledge about breast cancer (t=7.79, p <.001), breast cancer risk awareness (t=2.05, p <.05), self-competency of breast self-exam (t=8.27, p <.001), and intention to teach breast self-exam (t=3.87, p <.001). CONCLUSION: The integrated breast cancer prevention education was useful to improve not only knowledge about breast cancer but competency in performing breast examination for nursing students who acquired technical skills from various simulation nodules. As the program helped the students to be prepared as confident educators, future application of the module is recommended for academic curricula.

One of the most difficult problems to damage in dentistry is an odontogenic infection. These infections may range from low-grade, well-localized infections that require only minimal treatment to a severe, life-threatenig fascial space infection. Although the overwhelming majority of odontogenic infections are easily managed by minor surgical procedures and supportive medical therapy that includes antibiotic administration, the practitioner must constantly bear in mind that these infections may become severe in a very short time. We made an investigation was targeting on 78 male and 47 female patients (125 patients in total) who had been hospitalized because of the fascial space abscess on the oral and maxillofacial area and gained a complete recovery in Daegu Catholic University Hospital, Oral and Maxillofacial Surgery from January 1999 to December 2003. By tracing their charts, we could grasp the characteristics such as age, gender, the time of breakout and specific areas of the attacks, making a conclusive study of the statistical analysis and finally, we could reach conclusions. Now, we report the conclusion from the investigation with the literature. The proportion of males and females was approximately 3 to 2, and in age group, patients under 10 years old marked the highest, 22.4%. The patients between the age of 10 and 40 were only 14.4%, yet those who were between 40 and 80 marked 53.6% in contrast. In the monthly distribution, the order was Dec.(13.6%)-Sep.(12%)-Jan.(10.4%) and in seasonal distribution, it was winter(30.4%)-fall(28%)- summer(24.4%)- spring(19.2%). Considering the medical history, D.M. was the highest which was 30.3%, hypertension marked 24.4%, and the patients with both D.M. and hypertension were 9.0%. The major cause of infection of oral and maxillofacial areas was odontogenic infection, which marked about 96%, and especially the cases related to dental caries occurred most frequently, which was 51.2%. In the number of relaxed fascial space, single fascial space was 81.6%, and in the degree of relaxation of fascial space, the buccal space abscess marked 40.8%, following submandibular space abscess, which was 30.4%.

BACKGROUND: The main causes of thrombocytopenia in cirrhosis are thought to be platelet destruction and the reduction of thrombopoietin (TPO) expression in the liver. Immature platelet fraction (IPF) has been measured by a fully automated analyzer (Sysmex XE-2100, Japan) as reticulated platelet (RP), which is reflected with thrombopoiesis in bone marrow. In this study, we tried to compare the percentage of IPF (IPF) with that of RP (RP) in patients with liver cirrhosis (LC) and controls. METHODS: We compared IPF to RP in 72 liver cirrhosis patients and 30 healthy normal controls. RP was stained with acridine orange, followed by FC500 (Beckman Coulter, USA) analysis and the IPF was identified by flow cytometry with the use of a nucleic acid specific dye in the reticulocyte channel on the Sysmex XE-2100 (TOA Medical Electronics Co., Ltd., Japan). RESULTS: IPF value in the healthy control was 2.2% (1.7-5.2). RP and IPF were significantly higher in the patients with liver cirrhosis (P<0.05). IPF appeared to be correlated with RP (y=0.19x+3.35, r=0.34, P<0.05). In ROC for diagnosis of LC, IPF was significantly more useful than RP. CONCLUSIONS: This results show that a rapid, inexpensive automated method for measuring the IPF is feasible and should become a standard parameter in evaluating reticulated platelets.

During thalamotomy, we have to use the various kinds of brain reference points. From 1989 to 1992, the authors performed streotactic thalamotomy or pallidotomy in 169 patients suffering from tremor. We measured and estimated the important intracerebral reference points. These data were very meaningful for stereotactic functional neurosurgery in the Korean medical community because it is obtained from Korean people. We have also estimated the average location of targets for tremor submission.

BACKGROUND: Coronary angioplasty has been replacing coronary artery bypass grafting (CABG) because of the relative advantage in terms of recovery time and noninvasiveness of the procedure. Compared to other Organization for Economic Cooperation and Development (OECD) countries, Korea has experienced a rapid increase in coronary angioplasty volumes. METHODS: We analyzed changes in procedure volumes of CABG and of percutaneous coronary intervention (PCI) from three sources: the OECD Health Data, the National Health Insurance Service (NHIS) surgery statistics, and the National Health Insurance claims data. RESULTS: We found the ratio of procedure volume of PCI to that of CABG per 100,000 population was 19.12 in 2014, which was more than triple the OECD average of 5.92 for the same year. According to data from NHIS statistics, this ratio was an increase from 11.4 to 19.3 between 2006 and 2013. CONCLUSION: We found that Korea has a higher ratio of total procedure volumes of PCI with respect to CABG and also a more rapid increase of volumes of PCI than other countries. Prospective studies are required to determine whether this increase in absolute volumes of PCI is a natural response to a real medical need or representative of medical overuse.

BACKGROUND: The purpose of this study is to evaluate the concentration of cardiovascular surgical procedures in a metropolitan area and investigate the perception of specialists regarding governmental policies to resolve this imbalance. METHODS: From March to May 2015, surveys were distributed to members of the Thoracic and Cardiovascular Surgery Association. The final pool of research subjects consisted of 75 respondents. Subjects were queried regarding the concentration of cardiovascular operations in metropolitan areas, alternatives to the imbalance, and governmental policies to resolve the inequalities. RESULTS: Survey participants responded that South Korea needs governmental policies to alleviate the concentration of cardiovascular surgery patients in large metropolitan hospitals. Participants agreed that the freedom to choose medical institutions and improved accessibility to metropolitan hospitals due to advanced transportation systems were some of the causes for the concentration. A majority (98.7%) of respondents thought establishing thoracic and cardiovascular surgery centers in provinces was an appropriate solution to alleviate the concentration. Thoracic and cardiovascular surgery specialists were ranked as the number one group on which to focus development. CONCLUSION: Developing and carrying out policies to establish thoracic and cardiovascular surgery centers in provinces will alleviate the regional imbalance in available heart surgery services and an overall improvement in cardiovascular disease treatment in South Korea.

Objective:
This study aimed to determine the tic aggravation event rate and cumulative incidence rate in the use of methylphenidate (MPH) treatment in attention-deficit/hyperactivity disorder (ADHD) and the factors that influence tic aggravation.
Methods:
We conducted a retrospective chart review of children and adolescents aged between 6 to 15 years, who were diagnosed with ADHD from January 2017 to December 2019. A total of 121 subjects were included. The MPH dosage, psychiatric family history, comorbidity and past history of tics were assessed through chart review and the psychological examinations data were included. Collected data were analyzed using Cox regression and Kaplan-Meier survival analysis.
Results:
Tic aggravation event rates without a past history of tics were 2.9% with MPH treatment in ADHD. Past history of tics, total MPH dosage and age were the factors associated with tic aggravation ([HR 21.46, p<0.001], [HR 0.94, p=0.023], [HR 0.79, p=0.021] for each). Cumulative incidence of tic aggravation was different between groups with or without past tic history. When treated with MPH, all tic aggravation appeared within approximately eight months but for subjects with a past history of tic, aggravation showed within approximately six months (p<0.001).
Conclusion
Tic aggravation event rate was significantly low especially in the group without a past history of tics with the use of MPH in ADHD. However, a thorough assessment of past history of tics, and close monitoring during the first six-eight months of treatment with MPH is needed to avert a potential worsening of tics.
