The purpose of this study is to grasp the nature of health behavior to pactice in order to keep and improve the optimal health in the current status of the cancer patients. The subjects were 21 cancer patients, who knew about their disease for themselves, could communicate without mental disease history, and could understand the purpose of this study and cooperate, in a university hospital in Seoul. The data were collected by direct interview from July 15 to Oct. 17, 1994. The interview took about 1~2hours per one time for each paitent by unstructural and open questions. And they were classified into some similar contents on the basis of the phenomenological analysis and categorized. The analyzed results are as follows: 1) In the daily life before and after diagnosis as cancer patients, they were categorized into 6 areas-the state of movement, sleeping, nutrition and diet, society and economy, drinking and somking, and recognition of their health. 2) In the experience of health behavior of cancer patents, they were categorized into 7 areas-the state of movement, sleeping, nutrition and diet, society and economy, drinking and smoking, recognition of their health, and psychology etc. According to the analyzed results of daily life before diagnosis as cancer patients, it turned out that they didn't recognize the problems for their health habit and made their disease state bad by irresolute characteristics which hesitated to practice rightly, renunciation, and irresponsibility and so on, even if they had much interests in their health and were motivated. Therefore, it is necessary to recognize and have an individual-centric interests in order to change the pattern of life for optimal health state to some extent. In the health behavior of cancer patients, it turned out that they had interests in the state of nutrition and diet the most. Even though they experienced the change of serious nutritive state due to the bad gastroenteric trouble by anticancer treatment, they were trying to have a regular eating habit refraining from irritant food and use folk remedies or healthy food temperating the taste food thoroughly, they also showed the sensitive response for nutrition. In addition, they appeared to use the traditional medical treatment or the folk remedies very seriously without abuse. In consideration of it, it is desirable to use them together with the modern medical treatment intercomplementarily and necessary to look into the types for cancer patients and their benefits.

Objective : Small unruptured aneurysms (<5 mm) are known for their very low risk of rupture, and are recommended to be treated conservatively. However, we encounter many patients with small ruptured aneurysms in the clinical practice. We aimed to investigate the incidence and characteristics of patients with small ruptured aneurysms. Methods : We reviewed all patients admitted to our hospital with subarachnoid hemorrhage from January 2005 to December 2015. The patients were divided into two groups : those with aneurysms <5 mm (group S) and those with aneurysms ${\geq}5mm$ (group L). The patient's age and sex, size and location of aneurysms, and risk factors such as hypertension, diabetes, alcohol use, and smoking were compared between the two groups. Results : Eight-hundred eleven patients were diagnosed with ruptured aneurysms, and 337 (41.6%) were included in group S. The mean size of all aneurysms was $6.10{\pm}2.99mm$ (range, 0.7-37.7); aneurysms with a diameter of 4-5 mm accounted for the largest subgroup of all aneurysms. Female sex was significantly associated with the incidence of small ruptured aneurysms (odds ratio [OR] 1.50, 95% confidence intervals [CI] 1.02-2.19, p=0.037). Despite female predominance in the incidence of small ruptured aneurysms, the proportion of small ruptured aneurysms in young (<50 years) men was high. In men, there were no significant differences regarding the location of the aneurysms between group S and group L (p=0.267), with the most frequent location being the anterior communicating artery (ACoA) in both group S (50.9%) and group L (51.4%). However, in women, there were significant differences regarding the location of the aneurysms between group S and group L (p=0.023), with the most frequent locations being the ACoA (33.0%) in group S, and the posterior communicating artery (30.6%) in group L. In women, two locations were significantly associated with small (<5 mm) ruptured aneurysms: the ACoA (OR 2.14, 95% CI 1.01-4.54, p=0.047) and anterior cerebral artery (OR 3.54, 95% CI 1.19-10.54, p=0.023). Multiplicity and smoking were significantly associated with large (${\geq}5mm$) ruptured aneurysms in women. The use of alcohol was related to small ruptured aneurysms in men over 50 years of age (OR 2.23, 95% CI 1.03-4.84, p=0.042). Conclusion : In this study, small (<5 mm) ruptured aneurysms exhibited different incidences by age, sex, location, and risk factors such as multiplicity, smoking, and alcohol use.

BACKGROUND/OBJECTIVES: Ginseng extract (GSE) and taurine (TR) are widely used antifatigue resources in functional foods. However, the mechanism underlying the antifatigue effects of GSE and TR are still unclear. Hence, we investigated whether GSE and TR have synergistic effects against fatigue in mice. MATERIALS/METHODS: L6 cells were treated with different concentrations of TR and GSE, and cell viability was determined using 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium. Oxidative stress was analyzed by immunocytochemistry using MitoTracker^TM Red FM and an anti-8-oxoguanine antibody. Respiratory gas analysis was performed to investigate metabolism. Expression of an activated protein kinase was analyzed using immunohistochemistry. Gene expression of cluster of differentiation 36 and pyruvate dehydrogenase lipoamide kinase isozyme 4 was measured using reverse transcription-polymerase chain reaction. Mice were orally administered TR, GSE, or their combination for 30 days, and then fatigue-related parameters, including lactate, blood urea nitrogen, and glycogen, were measured after forced swimming. RESULTS: TR and GSE reduced oxidative stress levels in hydrogen peroxide-stimulated L6 cells and enhanced the oxygen uptake and lipid metabolism in mice after acute exercise. After oral administration of TR or GSE for 30 days, the fatigue-related parameters did not change in mice. However, the mice administered GSE (400 mg/kg/day) alone for 30 days could swim longer than those from the other groups. Further, no synergistic effect was observed after the swimming exercise in mice treated with the TR and GSE combination for 30 days. CONCLUSIONS: Taken together, our data suggest that TR and GSE may exert antifatigue effects in mice after acute exercise by enhancing oxygen uptake and lipid oxidation.

1959년도 Satomura가 분광 도플러 초음파를 이용하여 시간변화에 따른 적혈구의 속도를 표현하였고 Kato가 혈류의 방향을 알 수 있는 제로베이스 선(Zerobase line)을 정의하면서 혈류의 방향을 알 수 있게 되었다. 이는 현재 폭넓게 사용하고 있는 삼상파 (Triphasic), 이상파(Biphasic), 단상파(Monophasic) 분류의 기초가 되었다. 하지만 위와 같은 분류는 임상 환경에서 사용 의미와 시점에 사용자들에게 혼란을 주는 한계가 있었고 이와 같은 결과로 미국의 혈관의학회(Society for Vascular Medicine, SVM)와 혈관초음파학회(Society for Vascular Ultrasound, SVU)가 구성한 공동 위원회에서 도플러 파형 해석 합의문(Consensus document)을 선언하였다. 본 연구에서는 이 합의문을 고찰하고 국내 혈관 초음파 임상 현장에서 사용될 수 있는 명명법과 수식어를 제언하고자 하였다. SVM과 SVU가 구성한 공동 위원회에서는 동맥 삼상파(Triphasic waveform)와 이상파(Biphasic waveform)의 해석의 모호함을 이유로 사용을 지양하고 다상파(Multiphasic waveform)로 사용하길 권고 하였다. 또한 임상 환경에서 항상 해석의 문제가 되었던 단상파이면서 고저항성 파형인 하이브리드 형태 파형을 중저항성 파형(Intermediate resistive)으로 명명하기로 합의하였다. 또한 판독의사와 초음파사간에 의사소통의 효율성을 높이기 위해 파형 해석을 주 설명어(Main descriptor)와 수식어(Modifier)로 분류하였고 다양하게 사용하던 동의어들을 통일하여 하나의 명명법으로 사용하도록 권고하였다. 본 문헌 고찰을 통해 임상에서 혈관 초음파 검사 직무를 수행하는 방사선사들에게 정확한 동맥 분광 도플러 파형 해석과 합의된 명명법을 제공하여 국민보건향상에 이바지할 수 있는 기초자료로 활용되기를 기대한다.

Objectives Recently, weight loss has emerged as a national concern in South Korea, and this has resulted in an increase in the frequency of use of central nervous system (CNS)-stimulating appetite suppressants. This study aimed to collect cases of psychotic disorders and bipolar disorders triggered by phentermine and phendimetrazine and explore the clinical features and courses. Methods In this retrospective study, we analyzed the electronic medical records of patients and selected eight patients who developed psychotic symptoms and manic symptoms for the first time after taking phentermine and phendimetrazine. All cases were reviewed, and their clinical features and course were summarized. Results All eight patients developed psychotic symptoms, and one had accompanying manic symptoms. The final diagnosis was appetite-suppressant-induced psychotic disorder in four patients, schizophrenia in three, and appetite-suppressant-induced bipolar disorder in one. In addition, three patients were diagnosed as having substance-use disorder. The key psychotic symptoms of these patients were hallucinations and paranoia. Conclusions These case findings suggest that phentermine and phendimetrazine can cause psychotic disorder, bipolar disorder, or substance use disorder and that medical professionals and the public should practice caution when prescribing and using these drugs.

Background: Dentists make various efforts to reduce patients' anxiety and fear associated with dental treatment. Dental sedation is an advanced method that dentists can perform to reduce patients' anxiety and fear and provide effective dental treatment. However, dental sedation is different from general dental treatment and requires separate learning, and if done incorrectly, can lead to serious complications. Therefore, sedation is performed by a limited number of dentists who have received specific training. This study aimed to investigate the proportion of dentists who practice sedation and the main sedatives they use in the context of the Republic of Korea. Methods: We used the customized health information data provided by the Korean National Health Insurance. We investigated the number of dental hospitals or clinics that claimed insurance for eight main sedatives commonly used in dental sedation from January, 2007 to September, 2019 at the Health Insurance Review and Assessment Service. We also identified the changes in the number of dental medical institutions by region and year and analyzed the number and proportion of dental medical institutions prescribing each sedative. Results: In 2007, 302 dental hospitals prescribed sedatives, and the number increased to 613 in 2019. In 2007, approximately 2.18% of the total 13,796 dental institutions prescribed sedatives, increasing to 3.31% in 2019. In 2007, 168 institutions (55.6%) prescribed N₂O alone, and in 2019, 510 institutions (83.1%) made claims for it. In 2007, 76 (25.1%) hospitals made claims for chloral hydrate, but the number gradually decreased, with only 29 hospitals (4.7%) prescribing it in 2019. Hospitals that prescribed a combination of N₂O, chloral hydrate, and hydroxyzine increased from 27 (8.9%) in 2007 to 51 (9%) in 2017 but decreased to 38 (6.1%) in 2019. The use of a combination of N₂O and midazolam increased from 20 hospitals (6.6%) in 2007 to 51 hospitals (8.3%) in 2019. Conclusion: While there is a critical limitation to the investigation of dental hospitals performing sedation using insurance claims data, namely exclusion of dental clinics providing non-insured treatments, we found that in 2019, approximately 3.31% of the dental clinics were practicing sedation and that N₂O was the most commonly prescribed sedative.
