  • E. pyrifoliae에 의한 과수 가지검은마름병은 국내에서 1995년 최초 발생이래 2016년까지 꾸준히 발생하여 과수농가에 피해를 주고 있는 세균병해이다. 가지검은마름병 발생 농가의 폐원조치 및 공적방제로 인한 경제적 피해 감소를 위하여, 병징이 관찰되는 이병조직 및 건전조직 내의 병원 세균을 검출하여 효율적 관리방안을 마련하고자 본 연구를 수행하였다. 가지검은마름병원세균의 검출은 genomic DNA 추출과정을 생략한 순수 균총만을 이용하는 colony-PCR을 이용하였으며, 이를 위해 ERIC 지역에서 제작된 가지검은마름병원세균 특이 프라이머 EpSPF/EpSPR 프라이머쌍을 선발하였다. 특이 프라이머를 활용한 colony-PCR 방법으로 2014-2015년 4-10월까지 사과나무 생육기간 동안 가지검은마름병 발생상황을 모니터링한 결과, $25^{\circ}C$ 일 평균 온도 기간인 5월 중순부터 7월 초순까지 발병이 가장 빈번하였다. 발병가지 내 병원세균의 존재유무 검정 결과 병징 부위와 이로부터 20 cm 내 건전조직에서만 병원세균이 지속적으로 검출되었다. 따라서 이미 발생한 가지검은마름병을 효율적으로 관리하기 위해 이병조직과 건전조직 경계 부위로부터 20 cm 이상에서 가지치기를 하는 것이 매우 적절할 것으로 판단된다.

  • Gastric cancer (GC) is one of the most common malignancies in the world. It is the first cause of cancer deaths in both sexes In Iranian population. Circulating insulin-like growth factor-one (IGF-1) levels have been associated for gastric cancer. IGF-1 protein has central roles involved in the regulation of epithelial cell growth, proliferation, transformation, apoptosis and metastasis. Single nucleotide polymorphism in IGF-1 regulatory elements may lead to alter in IGF-1expression level and GC susceptibility. The aim of this study was to investigate the influence of IGF-1 gene polymorphism (rs5742612) on risk of GC and clinicopathological features for the first time in Iranian population. In total, 241 subjects including 100 patients with GC and 141 healthy controls were recruited in our study. Genotypes were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay with DNA from peripheral blood. The polymorphism was statistically analyzed to investigate the relationship with the risk of GC and clinicopathological properties. Logistic regression analysis revealed that there was no significant association between rs5742612 and the risk of GC. In addition, no significant association between genotypes and clinicopathological features was observed (p value>0.05). The frequencies of the CC, CT, and TT genotypes were 97%, 3%, and 0%, respectively, among the cases, and 97.9%, 2.1%, and 0%, respectively, among the controls. CC genotype was more frequent in cases and controls. The frequencies of C and T alleles were 98.9% and 1.1% in controls and 98.5% and 1.5% in patient respectively. Our results provide the first evidence that this variant is rare in Iranian population and it may not be a powerful genetic predisposing biomarker for prediction GC clinicopathological features in an Iranian population.

  • Gorham-Stout disease (GSD)는 골용해와 함께 혈관 및 림프조직의 비정상적인 증식으로 골조직 파괴가 유발되는 매우 드문 질환이다. 아직까지 GSD의 정확한 병인 및 기전은 밝혀지지 않았다. 악성종양이나 신경병증, 감염과의 연관성은 불명확하며, 골조직이 있는 신체 어디에서든 기형적 혈관-림프관 증식이 발생할 수 있다. GSD 중 약 20%에서 유미흉을 동반하는데, 림프관 형성이상이나 가슴 림프관 손상에 의해 이차적으로 발생한다. 급격한 호흡부전으로 이어질 수 있어 불량한 예후인자로 알려져 있지만, 질환 자체의 희귀성 때문에 현재까지 확립된 표준치료법은 없다. 본 증례는 유미흉을 동반한 생명을 위협하는 GSD 환자에서 적극적인 외과적 중재술 후 mTOR inhibitor 및 beat-blocker 복합요법을 적용하여 치료에 성공한 보고이다. 환자는 가슴림프관 결찰술 및 흉막유착술을 시행 받았으나, 일시적 증상호전 이후로 유미흉 및 호흡곤란의 재악화 반복되었다. 양측 흉막유착제거 및 폐쇄 흉강삽관술과 함께, beta-blocker와 mTOR inbititor 경구투약을 시작했다. 약물투약 1개월 후 유미흉 재발없이 호흡 안정적으로 유지되어 산소 보조치료 없이 퇴원하였다. 현재 11개월째 지속적으로 약물 투약 중으로, 약물 부작용 및 추가적인 입원치료 없이 정상적인 일상생활을 유지하고 있다. 추후 유미흉을 동반한 GSD 환자의 치료에서, 적극적인 외과적 중재술과 함께 경구 mTOR inhibitor 및 beta-blocker 복합요법을 고려해 볼 수 있겠다.

  • Objectives : The objective of this study was to analyze cognition and status of oral health education of dental hygienists who manage the patients visiting dental clinics and to utilize the findings as continuous study data required for development of systematic oral health education program for management of peridontal disease of adults. Methods : Survey was carried out for 261 dental hygienists working in dental clinics who are performing oral health education of patients with peridontal disease living. Results : 1. In the socio-dynamic diagnosis, it was analyzed that, the younger the age is and the lower the career is, the more the work is centered around assisting medical treatment job and, the older the age is and the higher the career is, the work is centered around oral health education job. 2. In the behavioral diagnosis, it was analyzed that, as to source of knowledge acquisition, guide of dentists and senior dental hygienists was the highest and, as to education media, visual education and demonstration education were mainly used. 3. In educational diagnosis, as to the degree of knowledge about oral health education and the degree of practice, it showed that the degree of knowledge was lower than the degree of practice in peridontal disease process and oral prophylaxis as well as scaling part. 4. In both the cases of independent practice and group practice, it showed that the most frequent obstacle was insufficient educational materials and tools and it was analyzed that acquisition of new knowledge and technology is required as a matter to be improved. Conclusions : It seems to be required for the dental hygienists to develop detailed knowledge and professional technology in order to induce actions and motive of patients during oral health education of peridontal patients and to develop and produce data for efficient education of peridontal patients.

  • This study was performed to assess the nutritional status, frequency of visiting and necessity of nutrition programs for 157 elderly(male:49, female:108) visiting public health centers in Puchon. The purpose of the study was to provide the basic data for developing a nutrition service model. The subject were investigated by interviews with a questionnaire to obtain dietary data and other information related to public health center. Blood tests for analyzing biochemical status were also carried out. The elderly showed low income status. Ninety two percent of them showed their monthly income was less than 400,000 won and 72.6% was observed as having 30,000 won/month as their pocket money. The most frequent disease reported as having or being treated were hypertension(32.6%), rheumatic arthritis(28.5%), diabetes(10.2%), and stomach disease(8.2%) for males and hypertension(33.1%), diabetes(19.4%), rheumatic arthritis(16.7%), anemia(11.1%) for females. The nutrients whose daily intakes were less than 2/3 of RDA were calcium(37.5% RDA),vitamin A(49.9% RDA), iron(60.0% of RDA) and protein(62.0% RDA) for males and vitamin A(27.7% RDA), vitamin B$_2$(33.3% RDA), calcium(44.1% RDA), iron(53.3% RDA), and niacin(60.0% RDA) for females, respectively. Prevalence of anemia, assessed by hemogloben using WHO definition, were 4.1% for males and 18.5% for females. The percentage of males with hypercholesterolemia( 220 mg/dl) was 2.1% and 19.4% fir females, Two percent of males and 12.0% of females were observed as having a LDL-C higher than 165 mg/dl. The mean fasting blood glucose(FBG) level of males and female was 84.2 mg/dl and 101.7 mg/dl respectively. Two percent of males and 8.3% of females were found with a FBG higher than 140 mg/dl. Seventy one percent of elderly reported they were visiting public health centers at least once per week or more frequently. They were satisfied most with the low medical bills but showed the lowest satisfaction for the facilities of the public health centers. What the nutrition service programs wanted most was nutrition counseling and guidance.

  • Purpose: The aim of this study was to investigate the impact of preoperative low body mass index (BMI) on both the short- and long-term outcomes in patients with gastric cancer. Materials and Methods: A total of 510 patients with gastric cancer were divided into the following 3 groups: low BMI group (${\leq}18.5kg/m^2$, n=51), normal BMI group ($18.6-24.9kg/m^2$, n=308), and high BMI group (${\geq}25.0kg/m^2$, n=151). Results: There were significantly more stage III/IV patients in the low BMI group than in the other groups (P=0.001). Severe postoperative complications were more frequent (P=0.010) and the survival was worse (P<0.001) in the low BMI group. The subgroup analysis indicated that survival was worse in the low BMI group of the stage I/II subgroup (P=0.008). The severe postoperative complication rate was higher in the low BMI group of the stage III/IV subgroup (P=0.001), although the recurrence rate and survival did not differ in the stage III/IV subgroup among all the BMI groups. Low BMI was an independent poor prognostic factor in the stage I/II subgroup (disease-free survival: hazard ratio [HR], 13.521; 95% confidence interval [CI], 1.186-154.197; P=0.036 and overall survival: HR, 5.130; 95% CI, 1.644-16.010; P=0.005), whereas low BMI was an independent risk factor for severe postoperative complications in the stage III/IV subgroup (HR, 17.158; 95% CI, 1.383-212.940; P=0.027). Conclusions: Preoperative low BMI in patients with gastric cancer adversely affects survival among those with stage I/II disease and increases the severe postoperative complication rate among those with stage III/IV disease.

  • Purpose: This study was performed to investigate demographic and disease-related characteristics that influence lower urinary tract symptoms in middle-aged women. Methods: The participants in this study were 301 middle-aged women and they completed structured questionnaire between May to June, 2008. Lower urinary tract symptoms (LUTS) were measured with Bristol Female Lower Urinary Tract Symptoms-short form (BFLUTS-SF) and categorized as voiding, filling and incontinence symptoms. The data were analyzed by using descriptive statistics, t-test, ANOVA, Pearson Correlation Coefficient, and multiple regression with SPSS PC 15.0 version. Results: The participants who have higher economic status and drink alcohol were more likely to have LUTS score than other woman who have lower economic status and don't drink alcohol at all. Also, frequent childbirth experiences and chronic diseases conditions such as diabetes and heart disease are positively associated with LUTS score. The symptoms of filling and incontinence were affected by number of childbirth, alcohol drinking habit and chronic disease conditions while voiding symptom was influenced only by alcohol drinking habit. In multiple regression analysis, LUTS were significantly predicted by parity, drinking carbonated beverage and alcohol. Conclusion: For proper nursing care related to lower urinary tract symptoms, nursing intervention should focus on improving alcohol drinking habit and carbonated beverage comsumption.

  • Oral Lichen Planus(OLP) is a idiopathic chronic inflammatory disease with more difficult to clear and higher recurrent rate than cutaneous lesions. But, there has been no estabilished theories about the proper treatment for OLP. The purpose of this study is to examine the clinical feature, relationship with systemic disease and dental treatment of OLP patients of Korea and to gain helpful information about clinical characteristics and treatment of OLP. The subjects chosen for the study were 54 patients who had visited Department of Oral Diagnosis & Oral Medicine at Yonsei University Dental Hospital Dental Hospital and diagnosed as OLP. Previous clinical records has been reviewed and questionnaires, oral examination, laboratory examination were done and recorded. The following results were obtained : 1. Of the 54 patients, 21 were men and 33 were women with an average age of 47.8 years. 2. The most common intraoral site was bilateral buccal mucosa, followed by unilateral buccal mucosa, gingiva, vesibule, lip mucosa, glossal mucosa, palatal mucosa and mouth floor. 3. The mixed, erosive and reticular form of OLP was most frequent(83.3%) clinical form. 4. OLP patients with liver disease were 5, and drug medication patients were 7. But, we could not find its evidence of association with OLP. 5. Associated events on onset of symptom were stress, denture wearing, dental treatemtn, and common cold. 6. Associated symptoms were dry mouth, tingling, sore throat, and altered taste perception. 30.8% of patients had no specific associated symptoms. 7. Aggravating factors of symptom were peppery food, hot food, fatigue, toothpaste, salty food, sour food, tension, and conversation. Reducing factors were cold food, sleeping. 69.2% of patients had no specific reducing factors. 8. There were no significant differences between normal papulation and OLP patients in CBC, SGOT< SGPT, Serum iron, Total iron binding capacity. 66.7% of subjects were positive response to fungus study for Candida Albicans. The incidence of stress and dental treatment on onset of symptom appeared high in OLP patients. Especially, high incidence of positive response to fungus study for Candida albicans, prescription of anti-fungal agents and dental treatment considerations may be helpful to treatment of OLP.
