Background: The principal surgical technique for treating an abdominal aortic aneurysm since the 1960s has been the transperitoneal approach, yet there have been some recent studies that have reported improved surgical results with using the retroperitoneal approach. However, there are only limited clinical Korean studies that have, compared between the transperitoneal and retroperitoneal approaches. Material and Method: This study included 36 patients who had been diagnosed as having an aneurysm of the abdominal aorta and they were surgically treated between January 2001 and July 2007. The patients were subdivided into the retroperitoneal approach group (n=17) and the transperitoneal approach group (n=19), and they were compared in terms of the preoperative risk factors, the postoperative complications and the operative mortality. The risk factors of operative mortality risk and long-term survival for the 36 patients were assessed by the Kaplan-Meier method. Result: There were no significant differences between the groups in terms of gender, age, the underlying disease, a history of smoking, rupture of aneurysm, the preoperative symptoms, the operation time and the incidence of postoperative complications. However, the duration of postoperative fasting, the number of days of having an indwelling nasogastric tube and the length of the stay in the intensive care unit were significantly short for the retroperitoneal approach group (p<0.05). There was a 16.7% rate of operative mortality (6/36) and five of the deaths were attributed to preoperative ruptured aneurysm. On univariate analysis, a higher preoperative serum creatinine level (SCr ${\geq}$1.8 mg/dL, p=0.016) and ruptured aneurysm (p<0.001) were the significant risk factors of operative mortality. As assessed by the Kaplan-Meier method, the long-term survival was comparable between the groups and the five-year survival rate of all the patients was 57.5%. Conclusion: In the present study, a retroperitoneal approach has several advantages such as a shorter intensive care unit stay, a shorter duration of postoperative fasting and a shorter duration of an indwelling nasogastric tube. Therefore, unless there is any contraindication for a retroperitoneal approach, it could be considered as a primary surgical access for repairing an abdominal aortic aneurysm.

The treatment policy and prognosis are determined based on the final stage of lung cancer patients. The final stage of lung cancer patients is determined based on the T, N, and M stage classification table provided by the American Cancer Society (AJCC). However, the final stage of AJCC has limitations in its use for various fields such as patient treatment, prognosis and survival days prediction. In this paper, clustering algorithm which is one of non-supervised learning algorithms was assessed in order to check whether using only T, N, M stages with a data science method is effective for classifying the group of patients in the aspect of survival days. The final stage groups and T, N, M stage clustering groups of lung cancer patients were compared by using the cox proportional hazard model. It is confirmed that the accuracy of prediction of survival days with only T, N, M stages becomes higher than the accuracy with the final stages of patients. Especially, the accuracy of prediction of survival days with clustering of T, N, M stages improves when more or less clusters are analyzed than the seven clusters which is same to the number of final stage of AJCC.

타석증을 동반한 만성 악하선 타액선염의 경우 악하선 적출은 일반적인 치료 방법이다. 일반적으로 악하선 적출술은 수술의 용이성, 수술시야의 확보 등의 장점으로 구강외접근에 의해서 시행되어져 왔다. 그러나 시대적으로 심미적인 요구가 증대되고 있는 요즈음 구외 접근으로 인한 술후 반흔은 구외접근법의 가장 결정적인 단점이라 할 수 있다. 또한 설하선과 함께 적출하여야 할 경우 구내접근과 구외접근을 동시에 실시할 경우 술후 치유과정상의 후유증을 유발할 수도 있다. 반면에 구강내 접근에 의한 악하선의 적출은 수술상의 고도의 난이도로 수술자체의 어려움은 있으나 구강의 반흔을 남기지 않아 심미적으로 만족할 만한 결과를 얻을 수 있다. 이에 본 저자 등은 타석증을 동반한 악하선 타액선염의 환자에 있어 구내 접근으로 악하선 및 설하선 적출술을 시행하여 좋은 결과를 얻었기에 문헌고찰과 함께 보고하는 바이다.

Objective : Although transoral transpharyngeal approach is a very useful method for the lesions of craniovertebral junction, it is not frequently used because of anatomical unfamilarity, risk of cerebrospinal fluid(CSF) leakage, and resultant postoperative meningitis. To evaluate the usefulness of transoral transpharyngeal approach for various lesions of craniovertebral junction, clinical characteristics and the results of this approach are investigated. Methods : Transoral transpharyngeal approaches were performed in eight cases between 1996 and 1999. Among them, there were three basilar invaginations due to congenital anomalies, two odontoid type I fractures, two atlantoaxial dislocations, and one pseudotumor. Surgical methods included five cases of anterior decompression and posterior fusion, two anterior approaches for decompression and one transoral approach for biopsy. Results : This procedure allowed immediate clinical improvement in all cases. In seven patients with preoperative motor deficit showed a progressive neurological improvement. The follow-up plain x-rays demonstrated successful bony fusion in all patients. Only one patient suffered from postoperative wound dehiscence, but she completely recovered after wound revision. There was no complication of postoperative CSF leakages. Conclusions : Transoral transpharyngeal approach for the ventral lesions of craniovertebral junction, can be used as a relatively simple and effective method.

Purpose: This study investigated medical accessibility on optical stores and ophthalmic clinics of Seoul Special City and six other metropolitan cities. Methods: By using a number of households, population, optician stores, ophthalmic hospitals, and real estate (apartments) standard market price of Seoul Special City and six other metropolitan cities provided by the Commercial District Information System (2016.6) of Small Enterprise & Market Authority, we analyzed the level of healthcare accessibility and business area zones, Statistical analyses were performed with SPSS 18.0. Results: Inchon (household 2,227/population 5,723) had the highest household and population rate per optical store, and Gwangju (1,146/2,979) had the lowest. Gwangju (24,612/63,987) had the highest household and population rate per optical store, and Seoul (10,021/24,432) had the lowest. From the consumer and patient's point of view, lower household rate per optical store is a city with good accessibility to healthcare, but from an optical store and ophthalmic clinic's view, it will have great difficulty due to issues of competition. Conclusions: Consumers and patients should be the center of healthcare. A healthcare system that can provide smooth service anywhere anytime should be constructed. However, most metropolitan cities, including Seoul, have optical stores and ophthalmic clinics densely populated where profitability and liquidity are ensured and causing unbalanced distribution of healthcare. To solve such problems, we need proper distribution of optician stores according to the population proportion and industrial-educational research to find balance point of local healthcare.

골절이 아닌 정형외과적인 질환을 진단하는 것은 임상적으로 접근 할 때 쉽지 않은 부분이 아니라고 할 수 없다. 특히 일상 증상이 몇 주 이상 보이게 되는 경우에 초기 신체 검사에서 그 증상을 확인하지 못한다면 진단에 더욱 어려움을 갖게 된다. 이에 대해 초기 신체검사에서 이상을 확인하는 방법에 대해 고찰해보도록하겠다.

Lesch-Nyhan syndrome is a rare X-linked recessive genetic disorder. During purine metabolism, the hypoxanthine guanine phosphribosyl transferase (HGPRT) enzyme is deficient causing phosphoribosyl transferase to accumulate and resulting in excessive uric acid. Clinical symptoms include hypercalcemia, choreoathetosis, spasticity, mental retardation, and self-injury to lips, tongue or fingers. This results not only in pain caused by the self-injury but also secondary infection of the wound site and the esthetic damage of the soft tissue defect. Dental treatments include conservative methods using intraoral appliances such as soft mouthguards, fixed lip bumpers, and occlusal guards, and invasive methods such as extraction of all teeth or forming an artificial anterior open bite. We report two cases of Lesch-Nyhan syndrome patients with self-mutilation behavior; one was treated with a preservative method using a soft mouthguard, and the other was treated with extraction of all teeth.

This study was attempted to identify the media preferences and the reasons of cancer patients. The data collection was conducted on 76 people. and they are 6 men, 70 women with 38 breast cancer patients, and 38 patients with other cancers. For measuring tools, self-written questionnaires and Mandala paintings were used for single-time art therapy. The data analysis compared the results of technical statistics, independence verification and chi verification using the SPSS WIN ver.25.0 with the Mandala painting. There were no significant differences in media preference by age and duration of the disease, and there were significant differences in media preference by disease. In the Mandala painting, the characteristics of the medium and the factors of specific disease showed that there were reasons and effects of preference media choice. This study is meaningful in that it concentrated on the art therapy access and support in terms of the cancer outpatients, which have been concentrated on inpatients so that they shed light to the support and intervention needed by the outpatients, and can be used as basic data for the development of art therapy programs to help stabilize the mind of cancer patients in the future.
