  • Purpose: This study considered the effects and proper treatments of mandibular condyle fractures by comparing clinical differences and complications according to analysis and treatment plan. Methods: From September 2007 to August 2010, patients who were diagnosed with condylar fracture and monitored for more than 3 months were selected. Cases were divided in a reductive manner and evaluated by type and period of intermaxillary fixation (IMF), status of occlusion and trismus according to the Spiessle/Schroll method. A total 50 patients were examined. Results: The number of the unilateral condyle fractures was 45 and 30 patients had multiple fractures. Type of fracture was categorized by the Spiessle/Schroll method. There were 21 patients with type I, 11 patients with type II, 3 patients with type 3, 10 patients with type V and 5 patients with type VI; there were no patients with a type IV fracture. 11 patients were operated on with open reduction. Among them, 9 patients were type II and 2 patients were type I. For type I patients, an intra-oral approach was conducted with an endoscope and trocar. For 3 of the type II patients, an retromandibular approach was conducted and for the rest of the type II patients, the same approach as type I was used. The periods of IMF were 2.36 weeks (mean) in open reduction group and 2.9 weeks (mean) in closed reduction group and the total mean period is 2.78 weeks. All patients had stable occlusion after removing the IMF. Trismus occurred in 1 patient for open reduction and 5 patients for closed reduction. Facial nerve palsy was observed in one patient postoperatively that resolved after 6 months. Conclusion: In this study, similar prognosis was shown after an open and closed reduction was conducted. Therefore, treatments need to be planned depending on the degree of condyle fracture and the amount of displacement. Additionally, the period of IMF could be shortened with open reduction.

  • From August 1990 through December 1991, 14 patients[all males] underwent int-rathoracic muscle transposition of extrathoracic skeletal muscles to treat empyemas, 6 patients had tuberculous empyemas, 4 had chronic empyemas of unknown etiology, 3 had pos-tpneumonectomy empyemas, and 1 had postlobectomy empyema. 9 patients had associated bronchopleural fistulas, Their ages ranged from 22 to 67 years, with mean age of 45.1$\pm$17. 6[$\pm$S.D] years. The serratus anterior was transposed in 13 patients, the latissimus dorsi in 12. In 11 patients, both the serratus anterior and the latissimus dorsi were transposed. The omental flap also transposed in 3 patients. To reduce the dead space in the thoracic cavity, thr-oacoplasty was also carried out in 10 patients. The number of the partially resected ribs was 3.0$\pm$0.8[$\pm$S.D.]. All operations were single stage procedures, and all wounds were closed primarily, with no permanent tubes or chest wall openings. There was no hospital mortality, and so no subsequent operation has been required. Follow-up of the patients ranged from 5 to 16 months with a mean of 9.2$\pm$3.1[$\pm$S.D] months, All the patints had no further signs or symptoms of the original infection after discharge. We conclude that intrathoracic transposition of extrathoracic skeletal muscle is an excellent method of treatment for persistent, life-threatening intrathoracic infections.

  • Objectives: The number of patients undergoing oral anticoagulant therapy for cardiovascular and cerebrovascular disease is increasing. However, the risk of bleeding after tooth extraction in patients receiving warfarin is unclear. Here, we assess the risk of bleeding after tooth extraction in patients on warfarin. Materials and Methods: The study included 260 patients taking warfarin who underwent tooth extraction (694 teeth). The patients were divided into those whose teeth were extracted while they were taking warfarin, those who discontinued warfarin before extraction, and those who underwent extraction while receiving heparin bridging therapy. Bleeding complications in the two groups were compared. Results: Of the 260 patients, 156 underwent extraction while taking warfarin, 70 stopped taking warfarin before extractions, and 34 received heparin bridging therapy and stopped taking either medication before extractions. Bleeding complications occurred in 9 patients (3.5%) and 9 tooth sites (1.3%). Among the 9 patients with bleeding complications, 6 underwent extraction while taking warfarin, 2 stopped warfarin before extraction, and 1 underwent extraction after receiving heparin bridging therapy. No significant difference was seen between patient groups regarding bleeding after extractions (P=0.917). Conclusion: Warfarin use does not increase the risk of post-extraction bleeding and can therefore be continued during tooth extraction.

  • This study, which is proceeded in the department of nuclear medicine, aims at preventing unnecessary radiation exposure to the patients and the people near the patients by understanding and presenting the realities about the isolating period for the high dose radioiodine patients after total thyroidectomy in the 7 general hospitals in metropolitan area. Theoretically, the physical half-life of the high dose radioiodine is 8 days. Radioiodine lower than 100 mCi usually is eliminated all in 2 days 1 night considering the biological half-life and the amount of excreting radioiodine The hospitalization standard of the patients treated with high-dose radioiodine therapy has been established according to the fact above. Investigation of the data and questionnaire from the hospital have proven that some hospitals didn't even measure the acceptable dose because of the faith in the vague data. Besides, the some of those inevitably let the readmitting patients exceeding the acceptable dose be in the general ward, not in the isolation ward, because the number of the isolation rooms is relatively smaller than the patients. Thus, we want to contribute that patients understand the realities and the hospitals consider the relevant problem actively so that the problem will be settled by this journal.

  • Background: Acute auriculocephalic angle refers to an ear with helix that is spaced closely to the cranium. An increasing number of patients with acute auriculocephalic angle wish to undergo corrective operation for aesthetic purposes. However, there is a paucity of data regarding acute auriculocephalic angle. This paper proposes a treatment protocol for patients with acute auriculocephalic angle. Methods: We performed a retrospective analysis of patients undergoing acute auriculocephalic angle (4 patients, 6 ears). Patient records were reviewed for demographic data as well as auricular measurements at preoperative, immediate postoperative and final follow-up evaluations. Results: All of the patients were men with a mean age of 36.5 years (range, 23-52 years). The mean follow-up period was 47.5 months (range, 28-60 months). Postoperative auriculocephalic angle was close to the normal auriculocephalic angle ($25^{\circ}-30^{\circ}$) without notable scars. Moreover, the patients had minimal contractions of the skin flaps without any hematoma or relapse. Conclusion: We propose the following three treatment protocols for patients with acute auriculocephalic angle: the posterior auricular muscle should be sufficiently released, the mastoid area should be augmented using implants, the skin should be repositioned with a superior auricular flap.

  • Conventional high-flux hemodialysis (HD) is not as good as normal kidney function. Morbidity and mortality rates of patients receiving HD are still very high. To increase mid-to-large molecule clearance by combining diffusion and convection, on-line hemodiafiltration (HDF) is required. The objective of this study was to compare long-term survival rate of patients treated with on-line HDF to those who received conventional high-flux HD by reviewing data from Chonnam National University Hospital (CNUH). We selected patients who attended the 'CUNH dialysis center' and agreed to participate in the study. Overall, 40 patients with ESRD switched from high flux HD to on-line HDF or started on-line HDF from August 2007 to December 2009. Additionally, a total of 42 patients receiving conventional high-flux HD during the same period were enrolled. We then reviewed long-term survival rate of patients receiving on-line HDF over the next seven years. When we compared survival rates for seven years, the survival rate of the group receiving on-line HDF was 65% (26/40) while that of the group receiving the conventional high-flux HD was 54.8% (23/42). Although the number of patients was small to see survival difference clearly by one specific dialysis modality, there was somewhat difference in survival rate between the two groups. Indicators such as anemia, calcium-phosphate metabolism, nutritional status, treatment adequacy, and hospitalization were also improved in the group receiving HDF. Overall, results of our study showed beneficial effects of on-line HDF on clinical outcomes and survival in chronic HD patients.

  • The elderly patients are the most frequent users of digoxin because of increased prevalence of the two primary indications for digoxin therapy, fibrillation (AE) and congestive heart failure (CHF). This study performed to observe a variation in digoxin pharamcokinetic parameters in advancing age and changing kidney function and to compare the measured clearance with the calculated clearance. The 123 drug monitoring records of inpatients who had achieved steady state concentration of digoxin at a tertiary hospital from April 1999 to October 2001 were reviewed. In advancing age, measured digoxin clearance, volume of distribution and creatinine clearance were reduced. Compared with the calculated digoxin clearance, the measured digoxin clearance was more reduced in patients without CHF Especially, in elderly patients without CHF the measured digoxin clearance was lower than the calculated digoxin clearance. In contrast to nonCHF patients the measured value was greater than the calculated value in all CHF patients. Findings from this study indicate that the calculated digoxin clearance in elderly patients without CHF substantially overestimated the true clearance. Thus, it appears that the use of calculated digoxin clearance to estimate serum digoxin concentration may result in underestimation of the true serum concentration in a number of elderly patients without CHF.

  • Information on productivity of hospital personnel is required for optimum staffing and hospital management. This study deals with the quantitative aspects of workload of medical personnel in training hospitals by their specific characteristics. Specifically this study attempted to find relevant determinants of the productivity of medical personnel using multiple stepwise regression analysis based on data obtained from 135 training hospitals. The findings of this study were as follows: 1) Daily average number of outpatients and inpatients treated by a physician were 20.4 and 10.2, respectively. 2) Daily average number of patients cared by a nurse was 8.2. Daily average number of tests performed by pathologic technician and radiologic technician were 83.2 and 21.5, respectively. 3) Productivity of medical personnel were significantly different for the three groups of factors: hospital sire (number of beds, number of medical personnel per 100 beds): institutional characteristics (medical school affiliation, training type, profit status); and environmental factors (location, number of physician and beds per 1,000 population in the region). 4) The factors a(footing the productivity varied according to the types of medical profession: the number if beds, the number of physicians per 100 beds, training type, and profit status for physicians; the number of nurses per 100 beds, the number of beds, medical school affiliation for nurses; the number of physicians per 100 beds, the number of technicians per 100 beds, and ownership for pathologic technicians; the number o( technicians, training type, and the number of physicians per 100 beds for radiologic technician.
