파필로마바이러스(Human papilloma virus; HPV)는 자궁경부암의 주요한 원인균으로 30종 이상의 여성성기감염과 관련된 유전자형이 보고되었으며 자궁경부암과 관련성이 높은 고위험군과 관련성이 낮은 저위험군으로 나뉘어 진다. 최근 HPV 유전자형의 임상적 활용이 높아짐에 따라 신속하고 정확하게 HPV 유전자형을 선별할 수 있는 방법이 요구되고 있다. 본 연구의 목적은 여러 가지 분자생물학적 방법 중에서 정확도가 높은 DNA 염기서열분석을 이용하여 한국인 여성에서 HPV의 유전자형분포와 빈도를 구하고자 하였다. 전국 각 지역의 3,978명으로부터 채취한 자궁경부 검체에서 DNA를 추출하고, HPV L1 유전자 영역에서 PCR을 실시하였다. PCR 양성이 나온 경우 DNA 염기서열분석을 실시하였으며 GenBank BLAST program을 이용하여 HPV 유전자형을 분석하였다. 검사대상의 평균 년령은 37.6세였으며 년령 범위는 20-73세였고, 30대 여성이 검사를 가장 많이 실시하였다(42.2%). 총 3.978명 중에서 1,174명(1,174/3,978, 29.5%)이 HPV 양성을 보였으며 136명(11.6%)이 중복감염을 보여, 총 1,310개의 HPV 유전자를 분석하였다. 본 연구에서는 21종의 고위험군, 16종의 저위험군을 포함하여 총 37종의 HPV 유전자형이 검출되었으며, HPV 고위험군의 빈도는 69.8%(914/1,310), 저위험군은 26.0% (340/1,310)로 나타났다. 년령은 20대에서 HPV 양성률이 가장 낮았으며(69.5%), 60대 이상의 검체에서 발견된 HPV는 대부분이 고위험군이었다. 고위험군에서는 HPV 16형이 13.21%로 가장 높게 나타났으며, HPV 53형이 9.62%, 58형이 9.24%로 높게 나타났다. 다음으로 HPV 70(5.50%), 33(4.73%), 66(4.20%), 18(4.05%), 52 (4.05%), 31(3.97%), 56(3.51%)의 순으로 나타났다. 저위험군에서는 HPV 62(4.20%), 61(3.89%), 6(3.59%), 81(3.59%), 84(3.51%), 11(2.6%)의 순으로 검출되었다. DNA 염기서열분석을 이용한 한국인 여성의 HPV 유전자형빈도 분석 결과는 HPV의 역학적 연구와 백신개발을 위한 자료로 유용할 것이며, 자궁경부암의 치료와 관련한 특이적 HPV 유전자형 관련 연구에 도움을 줄 것으로 사료된다.

Purpose: The primary prevention for cervical cancer, the human papilloma virus (HPV) vaccination, has been available in South Korea and its importance has been emphasized publicly. The purpose of this study was to investigate the knowledge regarding HPV vaccination and identify the factors associated with HPV vaccination in female university students. Methods: A sample of 200 women among university students in Seoul was asked to answer a questionnaire on HPV-related knowledge and attitude, and influencing factors on HPV vaccination. Results: Among the respondents, 12.0% were HPV vaccinated. Overall HPV-related knowledge was low, and knowledge was not different between the vaccinated and unvaccinated groups. The vaccinated group demonstrated a higher score on the knowledge about the place where people could receive HPV vaccination and the cost of the vaccination than that of the unvaccinated group. The major influencing factor on vaccination was the parent's recommendation and the major barrier for vaccination was the cost of the vaccination. Conclusion: A broadened public campaign is recommended to increase the knowledge and positive attitude towards HPV vaccination for university female students as well as their parents.

Background: To identify the optimal cost effective strategy for the management of women having ASC-US who attended at King Chulalongkorn Memorial Hospital (KMCH). Design: An Economical Analysis based on a retrospective study. Subject: The women who were referred to the gynecological department due to screening result of ASC-US at King Chulalongkorn Memorial Hospital, a general and tertiary referral center in Bangkok Thailand, from Jan 2008 - Dec 2012. Materials and Methods: A decision tree-based was constructed to evaluate the cost effectiveness of three follow up strategies in the management of ASC-US results: repeat cytology, triage with HPV testing and immediate colposcopy. Each ASC-US woman made the decision of each strategy after receiving all details about this algorithm, advantages and disadvantages of each strategy from a doctor. The model compared the incremental costs per case of high-grade cervical intraepithelial neoplasia (CIN2+) detected as measured by incremental cost-effectiveness ratio (ICER). Results: From the provider's perspective, immediate colposcopy is the least costly strategy and also the most effective option among the three follow up strategies. Compared with HPV triage, repeat cytology triage is less costly than HPV triage, whereas the latter provides a more effective option at an incremental cost-effectiveness ratio (ICER) of 56,048 Baht per additional case of CIN 2+ detected. From the patient's perspective, the least costly and least effective is repeat cytology triage. Repeat colposcopy has an incremental cost-effectiveness (ICER) of 2,500 Baht per additional case of CIN2+ detected when compared to colposcopy. From the sensitivity analysis, immediate colposcopy triage is no longer cost effective when the cost exceeds 2,250 Baht or the cost of cytology is less than 50 Baht (1USD = 31.58 THB). Conclusions: In women with ASC-US cytology, colposcopy is more cost-effective than repeat cytology or triage with HPV testing for both provider and patient perspectives.

식도암은 예후가 좋지 않은 질환으로, 최근 식도암의 치료 성적을 향상시키기 위한 많은 노력이 행해지고 있으나 아직 그 결과는 만족스럽지 못하다. 이 연구에서는 지난 8년 간 동아대학교병원 흉부외과에서 치험한 식도암 환자를 대상으로 하여 조기 및 장기 성적을 분석함과 동시에 선택적으로 시행한 경부 임파절 절제술의 성적을 알아보고자 하였다. 대상 및 방법: 1995년 1월부터 2003년 8월까지 동아대학교병원 흉부외과에서 식도암으로 식도절제술을 받은 70명의 환자 중 근치적 절제가 가능하였고, 중복암이 동반되어 있지 않으며, 술 전 보조요법을 받지 않은 식도암 환자 51명을 대상으로 하여 임상적 자료를 후향적인 방법으로 조사하였다 식도 절제는 대부분 우측 개흉술을 이용하였고 대부분의 문합은 경부에서 시행하였다. 1997년 후반부터 선택적인 환자에서 경부 임파절 절제술(3-field ltmph node dissection)을 시행하였다. 결과: 남녀 비는 46 : 5였고, 중앙 연령 값은 60세였다. 식도암의 위치는 상흉부 10명(19%), 중흉부 21명(41%), 하흉부 20명(40%)이었고, 조직학적으로는 편평상피세포암이 46명(90%)으로 가장 많았고 소세포암이 2명, 선암, 선암-편평상피세포암과 미분화세포암이 각각 1명씩이었다. 술식은 경부문합이 41명, 흉부문합이 10명이었으며, 2-field lymph node dissection을 40명에서 3-field lymph node dissection을 11명에서 시행하였다. 술 후 병기는 I기 9명(17.6%), IIA기 20명(39.2%), IIB기 7명(13.7%), III기 11명(21.6%), IVA기 2명(3.9%), IVB기 2명(3.9%)이었다. 술 후 원내 사망률은 3.9%(2명)이었고, 술 후 합병증은 24명(47%)에서 발생하였다. 수술 사망 예를 포함한 전체 환자의 1, 3, 5년 생존율은 각각 74.4%, 48.4%, 48.4%이었다. 경부 임파절 절제를 한 군은 4년 생존율이 50.5%로 2-field lymph node dissection을 한 군(48.9%)보다 높았으나 통계적 유의성은 없었으며, 호흡기 합병증의 빈도가 높았고 수술시간이 유의하게 길었다. 결론: 이상의 결과로부터 식도암에 대한 외과적 절제술은 비교적 낮은 수술 사망률로 시행할 수 있으며, 병기가 진행된 경우라도 적극적인 수술적 치료를 하는 것이 환자의 생존율을 향상시키는 데 도움이 된다고 생각한다. 또한 경부 임파절 절제의 필요성에 대해서는 좀 더 연구가 진행되어야 하리라 본다.

목적: 골반부 방사선 치료를 받은 자궁경부암 환자에서 골밀도 검사 부위인 요추부위와 대퇴골 경부에서 방사선 치료 범위에 인접한 부위와 원격 부위의 골밀도 양상 및 골밀도 관련 인자와의 관련성을 알아보고자 하였다. 대상 및 방법: 고신대학교 복음병원 방사선 종양학과에서 골반부 방사선 치료를 받고 외래에서 추적 관찰하면서 2002년 11월부터 2006년 12월까지 골밀도 검사를 받은 자궁경부암 환자중 96명을 대상으로 제 1 요추부위, 제 4 요추부위와 대퇴골 경부 전체 부위에서 T-score와 Z-score를 조사하여 각 평균치가 각 부위별로 유의하게 차이가 있는지 분석하였다. 환자군의 특성과 관련하여 연령, 체중, 체질량 지수(BMI), 방사선 치료 종료 후 골밀도 검사일까지의 경과 기간, 자궁강내 근접치료(ICR) 추가 유무, 여성 호르몬 치료(HRT) 여부에 따른 T-score와의 관계를 각 부위별로 분석하였다. 결과: 전체 연령대의 각 부위별 T-score의 평균치는 제 1 요추부위가 -1.94, 제 4 요추부위가 -0.42, 대퇴골 경부 전체가 -0.53이었고 각 부위별 Z-score의 평균치는 제 1 요추부위가 -1.11, 제 4 요추부위가 -0.40, 대퇴골 경부 전체가 -0.48이었다. 제 4 요추부위 및 대퇴골 경부의 T-score와 Z-score는 제 1 요추부위와 유의한 차이를 보였으나(p<0.05), 제4요추부위와 대퇴골 경부사이에는 유의한 차이를 보이지 않았다. 60세 미만의 연령군에서도 같은 결과를 보였다. 각 부위별 T-score 모두에서 연령, ICR 여부 변수에 대해서 유의한 음의 상관 관계를 보였고(p<0.05), 체중, HRT 여부 변수에 대해서는 유의한 양의 상관 관계를 보였다(p<0.05). 체질량 지수에 대해서는 제 4 요추부위와 대퇴골 경부의 T-score와 유의한 양의 상관 관계를 보였다(p<0.05). 각 변수들이 각 부위별 T-score에 미치는 고유한 영향력을 알아보기 위한 다중 회귀 분석에서 연령은 제 1 요추부위와 대퇴골 경부의 T-score와 유의한 음의 연관을 보였으나(p<0.05) 제 4 요추부위와는 유의한 연관이 없었다. 체중은 각 부위 모두에서 T-score와 유의한 양의 연관을 보였다(p<0.05). ICR 여부 변수는 제 1 요추부위의 T-score와만 유의한 음의 연관을 보였다(p<0.05). HRT 여부 변수는 제 4 요추부위와 대퇴골 경부의 T-score와 유의한 양의 연관을 보였다(p<0.05). 결론: 본 연구에서는 제 4 요추부위와 대퇴골 경부의 T-score와 Z-score가 제 1 요추부위의 값보다 유의하게 높은 결과를 보였는데 일반인을 대상으로 한 일부 연구와는 다른 결과였다. 각 부위 간의 의미있는 차이에 대해서 노화나 다른 요인의 영향을 고려해 볼 수 있으며 방사선 치료 범위에 인접하거나 포함된 부위에서 더 높은 T-score와 Z-score를 보인 점에서 그 중 방사선의 영향도 부분적으로 작용하였을 것으로 생각된다. 방사선 치료 환자군의 골밀도 특성의 임상적인 의미에 대한 장기간의 추가적인 연구가 필요하며 이에 따라서 방사선 치료 환자에서 골밀도 검사에 의한 골다공증의 진단에 영향을 줄 수 있을 것으로 생각된다.

The purpose of this study was to analyze womens' health problems using Green & Kreuter's 1991 PRECEDE model and to develop a model for a womens' health care center located in the community. The subjects were recruited from Wonju City. 1. The results showed that 23% of the sample population felt there was a need for a womens' health care center. The mean number of health problems was 3.1. The prevalence rate, was 44.4%, and the rate for an artificial abortion, was 36.4%. Also 30.5% did not have a health examination in the past year. Women using the hospital for medical care accounted for 45% of the sample, while 40% used the drugstore. The average score on the HPLP was 2.41, and this was influenced by self-efficacy, family support, sexual role, and health locus of control. There are a few educational programs in the city provided by the Wonju Health Center and by community health nurse practitioners. 2. The nursing center, as defined in North America, is a nurse-anchored system of primary health care delivery or neighborhood health center. Centers offer various services ranging from primary care to the more traditional such as education, health promotion, wellness screening, and coordination of services by advanced practice nurses. For examples in Sweden MCH centers provide total services for childbearing women and their families, sexual counseling and education for adolescents, and screening by midwives for cervical cancer. 3. The developed model combines purpose, target population, organization, and services, and is related to health resources. The purpose is primary health care and promotion of the quality of life. The target population can be grouped according to the life cycle, (premarriaged age group, the childbearing/child rearing age group, and middle aged and elderly women) and focuses on self-help. The organization of the center includes an advisory committee to plan and evaluate, and a health services team that will be multidisciplinary to provide health care, counseling education, and research. The model development suggested that a variety of women's health care centers are needed to insure adequate management of women's health. Follow-up research using PROCEED is needed to analyze health outcomes. Also a health nursing specialist system is required to develop health promotion, and improve the quality of life of women.

In vitro cytotoxicity of 23 alkyl phenols (APs) on human cervical cancer cell lines (HeLa) was determined using the lactate dehydrogenase (LDH) cytotoxicity assay. Two different sets of descriptors were used to construct the calibration model based on Genetic Algorithm-Multiple Linear Regression (GA-MLR) based on the experimental data. A statistically robust Structure-Activity Relationships (QSAR) model was achieved ($R^2$=95.05%, $Q^2_{LOO}$=91.23%, F=72.02 and SE= 0.046) using three Dragon descriptors based on Me (0D-Constitutional descriptor), BELp8 (2D-Burden eigenvalue descriptor) and HATS8p (3D-GETAWAY descriptor). However, external validation could not fully prove its validity of the selected QSAR in characterization of the cytotoxicity of APs towards HeLa cells. Nevertheless, the cytotoxicity profiles showed a finding that 4-n-octylphenol (4-NOP), 4-tert-octyl-phenol (4-TOP), 4-n-nonylphenol (4-NNP) had a more potent cytotoxic effect than other APs tested, inferring that increased length and molecular bulkiness of the substituent had important influence on the LDH cytotoxicity.

Anaplastic carcinoma of thyroid gland account for no more than 10% of thyroid cancer, but it shows extremely poor prognosis. The purpose of this study is to review the outcome of patients with anaplastic carcinoma over the span of 5 years and to determine the patterns of clinical presentation, age, sex and other possible prognostic variables. We analyzed 30 cases of anaplastic carcinoma retrospectively from 1991 to 1995. There were 14 men and 16 women. There age ranged 33 to 75 years with a mean of 61.0 years. Sixteen patients presented with transformationqr of well differentiated carcinoma to anaplastic carcinoma, 1 with rapid in-crease in the size of long standing goiter, 8 with rapidly growing neck mass and 4 with meta static disease. Twenty-eight patients(93.3%) showed cervical lymphnode metastasis at presentation and twenty three patients(76.6%) showed laryngotracheal invasion. Nine patients (30.3%) showed distant metastasis. Treatment modalities included surgical resection, external irradiation, radioactive iodine and systemic chemotherapy. At decision making of treatment plan, we considered completeness of initial surgery, uptake rate of whole body radioactive io-dine scan, locoregional progression and distant metastasis. The median survival was 6.8 months and three cases survived beyond 12 months.

Background: Virtually all cases of cervical cancer are caused by persistent infections with a restricted set of human papillomaviruses (HPV). Cancer of the cervix is the third or even the second most common cancer in women worldwide, more than 85% of the cases occurring in developing countries, such as China and India, including the Republic of Kazakhstan. The purpose was to determine the HPV type distribution to evaluate efficacy of vaccination and adjust cancer prevention strategy in Western Kazakhstan in the future. Materials and Methods: A retrospective analysis was conducted of data obtained from PCR laboratories in 4 regional centers for the time period covering 12 months, 2013-2014, using AmpliSens$^{(R)}$ Real-Time PCR kits for HPV testing of 12 genotypes (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 59). Results: A total of 1,661 persons were HPV tested within 2013-14, but a proprotion examined for 16 and 18 genotypes only (563) was not been included for statistic analysis of distribution and ratio of the most common genotypes. Males accounted for only a small number (N=90 in total). Conclusions: Total number of the HPV-positive appeared to be 26.0%, or 286 of N=1098. Types distribution was as follows: type 16 (10.7%), 39 (5.83%), 51 (5.27%), 31 (4.85%), 56 (4.58%), 18 (3.61%), 59 (2.64%), 58 (2.22%), 35 (1.94%), 33 (1.25%). Overall the HPV infection was highest in 16-29 years old (62.4%) and decreased with age. Total prevalence of the HR-HPVs amongst male population was 21.4% with top five types 16, 18, 39, 51, 31. Trends forcorrelations between Aktau site and type 33 (Cramer's V 0.2029), between Caucasian ethnicity and type 33 (Cramer's V .1716), and between European ethnicities in Uralsk and type 45 (Cramer's V .1752) were found. Of N 563 tested separately for 16 or 18 types, 13.6% were positive. As a whole, the distribution of 16/18 types had a ratio of 3.53:1. Given the vaccine-targeted type 16 is widely spread amongst this regional population, HPV immunization program of adolescent girls 10-13 years should be implemented appropriately.

Purpose: To investigate the clinical features and prognosis of papillary thyroid carcinoma (PTC) with a background of benign disease. Method: A total of 709 patients with papillary thyroid carcinoma undergoing surgical resection were analyzed retrospectively. In 147 patients who underwent surgery for benign thyroid disease, incidental PTC (IPC group) were identified by intraoperative or postoperative pathological examination of surgical specimens but were not detected by preoperative imaging studies. In the other group, according to the pathological examination with or without co-existing benign thyroid disease, 253 cases were clarified as concomitant PTC and 309 cases were clarified as dominant PTC. Results: Incidental PTC was more common in women, about 85.7%, the mean age was $47.6{\pm}11.3$ years old. Average tumor diameter was $4.4{\pm}2.2$ mm, multiple lesions accounted for 12.9% (19/147), and the cervical lymph node metastasis rate was 6.1% (9/147). After radical resection 8 cases recurred, the median time of recurrence was about 12 months (0.5 to 162), there was no tumor-related death. The tumor-free survival rates were 97.3%, 95.9%, 91.5%, and 79.3% in 1, 5, 10 and 14 year respectively. Conclusion: Incidental PTC with a background of benign lesions is common, and the generally good prognosis can be attributed to tumor early detection and early treatment. On the intraoperative finding of incidental PTC, lobectomy (unilateral) or total thyroidectomy (bilateral) should be the first choice, but with a postoperative pathologic finding of incidental PTC, further treatment, such as completion thyroidectomy or immediate lymph dissection is not necessary. Central lymph node dissection is also not needed unless lymphadenectasis is present.
