Background: The number of cases employing thoracic endovascular aortic repair (TEVAR) has been increasing due to lower morbidity and mortality compared to open repair technique. The aim of this study is to evaluate the outcome of TEVAR for thoracic aortic diseases. Materials and Methods: Sixteen patients underwent TEVAR from October 2003 to April 2010. Mean age at operation was 59 years (20~78 years), and 11 were male. Indications for TEVAR were large aortic diameter (>5.5 cm) upon presentation in 6 patients, increasing aortic diameter during the follow-up period in 4, traumatic aortic rupture in 3, persistent chest pain in 2, and ruptured aortic aneurysm in one. The mean diameter, length and the number of the stents were 33 mm (26~40 mm), 12 cm (9.5~16.0 cm), and 1.25 (1~2), respectively. Aortography employing Multi-detector computerized tomography (MDCT) technique was performed at one week, and patients were followed up in the out-patient department at one month, 6 months, and one year postoperatively. Results: Primary technical success showing complete exclusion of the aneurysm was achieved in 15 patients. One patient showed a small endo-leak (type 1). Four patients developed perioperative stroke: Three recovered without sequelae, and one showed mild right-side weakness. There was no operative mortality. Diameter of the thoracic aorta covered by stent graft changed within 10% range in 12 patients, decreased by more than 10% in 3, and increased by more than 10% in one during mean follow-up duration of 18 months (1~73 months). There was no recurrence-related death during this period. Conclusion: Intermediate-term outcome after TEVAR was encouraging. Indications for TEVAR could be extended for other thoracic aortic diseases.

This research objected to the diagnosed patients as acute lymphoblastic leukemia, acute myelogenous leukemia, neuroblastoma, non-Hodgkins lymphoma, Hodgkin's disease, kidney tumor, myelodysplastic syndrom and juvenile chronic leukemia after admission in the 'P' hospital in Pusan from Aug. 1. 1999 to Jan. 31. 2000. The results of this study are summarized as follows. 1. On the specific character between the experimental(exp.) group and the control (con.) group : there were 7 of 4-7 years old patients(the most) in the experimental group(53.8％), 5 of 12 years old or older patients in the control group (38.5％). Patients who experienced operation were 7 in the exp. group(53.8％) and 6 in con. group(46.2％). The largest number of the patients' diagnosis was acute lymphoblastic leukemia by 5 in the exp. group(38.5％) and 4 in the con. group (30.8％). The hardest nausea came on the second day by 5 in the exp. group(38.5％), 9 in the con. group(69.2％). 2. P-score of the nausea vomiting on the number of daily anticancer drug administration : first day, the exp. group got 9.6 and the con. group 17.6(P = 0.03). 2nd day, 10.9 and 19.4(P = 0.00), 3rd day, 10.6 and 18.3(P = 0.00), 4th day 10.0 and 18.0, 5th day 10.9 and 16.8(P = 0.05). The score showed statistically significant difference(P < .05). 3. Oral intake didn't show statistically significant difference between two groups. However the average of Oral intake of the exp. group was continually higher than the con. group except to the first day after administration. In conclusion, nursing intervention and nutrition care are much more needed on the 2-3th day after administration to reduce nausea vomiting, and for remission of nausea and enlarging oral intake it is utilizable to apply the easy, economic Oral Cryotherapy to the young patients who undergo chemotherapy.

Purpose: The purpose of this study was to examine the effects of resistant gait training with proprioceptive neuromuscular facilitation (PNF) on the walking and balancing abilities of chronic stroke patients. Methods: Twelve chronic stroke patients were randomly assigned to either a control group (n = 6) that underwent treadmill gait training or an experimental group (n = 6) that underwent resistant gait training using PNF. The interventions were performed five times per week for four weeks. Gait variables were measured using a GAITRite system (CIR System Inc, Clifton, NJ, USA) to examine changes in walking ability; the Berg balance scale (BBS) was used to measure changes in balance; and the activity-specific balance confidence scale (ABC) was measured to examine changes in confidence about balance. A Wilcoxon signed-rank test was used to examine intragroup differences before and after the interventions, and a Mann-Whitney U-test was used for intergroup comparisons of the effects of the interventions. All statistical significance levels were set to ${\alpha}=0.05$. Results: Both the experimental group and the control group showed significant intragroup improvement in walking speed, the number of steps per minute, stride length, double support time, balance, and confidence about balance after the interventions (p < 0.05). In intergroup comparisons after the interventions, the experimental group showed significant improvements over the control group in walking speed, the number of steps per minute, stride length, balance, and confidence about balance (p < 0.05). No significant difference in double support time was seen in the intergroup comparison after training (p > 0.05). Conclusion: This study applied resistant gait training using PNF to chronic stroke patients, and the results showed significant improvements in the patients' walking and balancing abilities. Therefore, resistant gait training using PNF is thought to be applicable as an intervention method for chronic stroke patients.

본 연구에서는 그동안 해외에서 주로 실행되어 왔던 빅데이터를 이용한 다양한 질병(독감, 폐렴, 수족구병) 환자수 예측 모델을 개발해 보았다. 기존의 환자수 예측이 병원에서 실제 환자수를 카운팅한 수를 수집하여 발표하는 시스템이라면, 이번에 개발한 연구 모델은 실시간으로 제공되는 질병 관련 단어 및 다양한 기후 데이터를 접목하여 기계학습 방법으로 알고리즘을 만들고, 이를 기반으로 정부에서 발표하기 전 환자수를 예측하는 모델이다. 특히 유행성 질병이 빠르게 확산될 경우, 실시간으로 전파 속도를 파악할 수 있다는 점에서 그 장점이 있다. 이를 위하여 구글 플루 트렌드에서 실패한 부분을 최대한 보완하여 다양한 데이터를 활용한 예측 모델을 개발하였다.

This study presents the status on drug prescription for clinic outpatients' bronchitis, gastritis, and gastric ulcer, and also the physician factors that affects their prescriptions. In this research project the physician factors are as follows: their demographic features, their work related features, education related features, drug information related features and drug promotion related features. The variables in drug prescriptions are drug expenses, daily drug expenses, days of medication, the highest price of the drugs used and the number of the different drugs used. Analysis of the use of prescription drugs was performed on NFMI(National Federation of Medical Insurance) 1994 medical expense claim data. Data on physicians' characteristics were collected by mailing surveys. Patients with secondary diseases were excluded. In this study, 388 adults with bronchitis, 1,038 children with bronchitis, 1,158 patients with gastritis, 369 patients with gastric ulcer were included. The older physicians tend to allow the lower drug costs: this explains that the older doctors who are more experienced less depend on the medicines. It can be also explained that doctors are likely to use the medicines that had been used for their intern and resident practice/training period. General practitioners give more intensive prescription compared to specialists. And specialists prescribed medicines to patients for longer period. The doctors' prescriptions for patients are largely affected by commercial sources. So objective and reliable sources for drug information is needed for patients' benefits. Physician factors explain better at the daily drug expenses, the drug price and the number of different drugs than days of medication. Gastric ulcer are better explained by the prescription model adopted in this study than other diseases.

Purpose: With the increasing number of polytrauma patients treated at high-level trauma centers, plastic surgery has entered the specialty of traumatology. Plastic surgeons specialize in the simultaneous surgical care of patients with facial or hand trauma and soft tissue injuries requiring microsurgery. The purpose of this study was to introduce the role of plastic surgery in a high-level trauma center. Methods: Between January 2020 and December 2020, 5,712 patients with traumatic injuries were admitted to the emergency department of a tertiary hospital. Of these 5,712 patients, 1,578 patients were hospitalized for surgical treatment and/or critical care. Among the 1,578 hospitalized trauma patients, 551 patients (35%) required at least one plastic surgery procedure. The patient variables included age, sex, etiology, the injured area, and injury characteristics. We also retrospectively investigated surgical data such as the duration of the operation, hospital stay, length of time from injury to surgery, and collaboration with other departments. Results: The most common injury referred to plastic surgery was facial trauma (41%), followed by hand trauma (36%), and soft tissue injuries requiring microsurgery in various parts of the body other than the hand (7%). The majority of facial and hand traumas were concomitant injuries. Sixteen percent of patients underwent collaborative surgical management for polytrauma involving both plastic surgery and another department. Conclusions: The role of plastic surgery in multidisciplinary teams at high-level trauma centers has become increasingly important. The results of this study may help in the development of multidisciplinary trauma team strategies and future workforce planning.

The incidence of hepatocellular carcinoma (HCC) in Malaysia for the year 2001 was 2.8 per 100,000 people. The mortality rate is increasing. A retrospective cohort study measuring the survival of HCC patients who received treatment in Selayang Hospital was conducted from 1 January 2003 to 31 December 2006. The main objectives of the study were to measure the survival of the patients and to understand the influencing factors, especially ethnicity. The subjects were newly diagnosed cases of HCC by CT scan and histopathological assessment who underwent futher investigations and treatments in Hospital Selayang (inception cohort). The survival time was measured from the date of diagnosis until the subjects died, or failed to follow-up at the end of the study period (31 December 2007). A total of 299 patients were selected with 95 patients dying, the majority among Chinese (39.1%). Subgroup analysis according to ethnicity proved significantly that Chinese patients who had smaller tumor, less number of nodules, low AFP level, Child Pugh Class A and received surgical treatment had a better median survival rate compared to other ethnic groups. Malay (cHR: 1.3, 95%CI; 0.89-1.85) and Indian (cHR: 1.3, 95%CI; 0.74-2.26) patients had a poor survival compared to Chinese patients, but not in the final model. Therefore ethnicity may play a role in survival of HCC patients, but not as a main hazard prognostic factor.

Presented in this paper the data from a chromosome study of 397 patients referred for suspected chromosmal abnormalities. Karyotypes were obtained using short-term blood culture and direct method. Of these 238 patients had normal chromosome complements; 159 (40.1%) patients had chromosome abnormality. Among all patients with chromosome abnormalities, 82.4% (131/159) had aberrations of chromosome number, the others 17.60/0 (28/159\ had aberrations of chromosome structure. Ten had a chromosome rearrangement; Five of them were reciprocal and five Robertsonian translocations. Four patients with pericentric inversions and one with paracentric inversions and four with isochromosomes were observed. There were four patients with marker chromosome, two patients had a chromosome insertion; and three others. (additional abnormal chromosomes.) Thus the results of the present study indicate the importance of cytogenetic evaluation in clinically abnormal patients.

Purpose : To determine normal CT number range of parotid gland by analyzing the change by age increase and the difference among individuals and between both sexes in CT number of normal parotid gland. Materials & Methods : 134 subjects who took the CT scan between the period of Jan. 1996 and Dec. 1997 at Yonsei University, Dental Hospital were selected. Criteria for selection were that the patients must be within the normal range clinically and radiologically, and the entire parotid gland on the axial view must be shown. Among the axial views. the one showing the greatest parotid gland size was selected and its CT number was recorded. Also. CT numbers from both masseter muscle were recorded as its control. Results : There was statistically significant correlation between CT number of right and left of parotid glands and masseter muscles. With the increase of age. there is a significant decrease in the CT number of parotid gland(p<0.05). There was no statistically significant difference in CT number between sexes except the 7th decade and beyond age group of parotid gland(p>0.05). Conclusion : As age increases, CT number of parotid gland has a tendency to decrease, and there is no significant difference in the CT numbers between left and right parotid gland. Therefore in the CT scan of patients suspected of having a salivary gland disease of the parotid gland. to consider normal range of the age-dependent CT numbers of parotid gland and compare the CT numbers of the right and left parotid gland might be useful in diagnosing the disease.
