Purpose: The purpose of this study was to compare knowledge level of those clinical nurses who received HPV vaccine and those who did not and their perception of the relatedness of HPV vaccine to causes of cervical cancer. Methods: A total of 249 clinical nurses were surveyed from June to July, 2009. The questionnaire originally developed by Kim & Ahn (2007) examined HPV-related knowledge originally and the tool for perception of the causes of cervical cancer was originally developed by Kim (1993). The total number of subjects equaled to: vaccination group of 52 (20.9%) and non-vaccination group of 197 (79.1%). Results: Vaccination group showed significantly higher score of both knowledge of HPV vaccination and the perception of the cause of cervical cancer in comparison to the nonvaccination group at (p<.05). Among 4 subscales of the perception of causes of cervical cancer, destiny and constitution subscale scores were significantly different between the two groups at (p<.05). Conclusion: Clinical nurses need to constantly update with current knowledge of HPV and be prepared with currently changing cancer prevention strategies, especially in cervical cancer.

Objectives: The purpose of this study is to report the improvement of recurrent cervical intraepithelial neoplasia (CIN) and chief complaint including dysmenorrhea, premenstrual syndrome after Korean medicine treatment. Methods: The patient who diagnosed CIN even after undergoing two times of loop electrosurgical excision procedure (LEEP) and complained dysmenorrhea with premenstrual syndrome was treated by acupuncture, moxibustion and herbal medicine as Ojeok-san-gami-bang along with mistletoe extract injection (Abnobaviscum^®). The effect of treatment was evaluated by the results of liquid based cytology and HPV genotyping. Other symptoms were evaluated according to the patient's subjective complaint. Results: Before the treatment, the result of cytology was low grade squamous intraepithelial lesion and a low-risk group for HPV was detected. At the first examination after treatment, cytology showed negative for intraepithelial lesion or malignancy and the HPV genotyping was negative. The result showed negative findings in 3 consecutive follow-up tests. In addition, the chief complaint and general conditions were improved. Conclusion: This study shows that the recurrent cervical intraepithelial neoplasia (CIN) was improved after the Korean traditional treatment and it can be effective medical alternatives or options for patients receiving mistletoe injection during follow-up.

Background: Currently it is believed that human papillomaviruses (HPV) are associated with the development of some oral/oropharyngeal cancers. It has been suggested that these viruses influence carcinogenesis in both smokers and non-smokers. Data on the prevalence of HPV in healthy adults are thus needed to estimate the risk of oral/oropharyngeal cancer. The aim of this study was to assess the prevalence of oral HPV in healthy female adults in Indonesia and Thailand. Materials and Methods: Healthy female students from the Faculties of Dentistry of Universitas Indonesia and Chiang Mai University were asked to participate in this pilot study. DNA was extracted from saliva specimens and screened for HPV16 and HPV18 using PCR. Results: The age, marital status and sexual experience of the subjects between the two countries were not significantly different. Eight (4%) and 4 (2%) samples were positive for HPV16 and HPV18, respectively. Fisher's Exact test found a significant difference between HPV16 positivity in subjects who were married and had sexual intercourse but not for HPV18. Conclusions: This study successfully detected presence of HPV16 and HPV18 DNA in a number of saliva samples from female dental school students. Marital status, experience of sexual intercourse and safe sexual practice are related to the possibility of finding HPV DNA finding in saliva. Dentists, physicians and other health care professionals may gain significant value from the findings of this study, which provide an understanding of the nature of HPV infection and its risk to patient health and disease.

Background: To determine the level of knowledge on human papillomavirus (HPV) infection and vaccination, and the attitude towards HPV vaccination in pediatricians, obstetricians and gynecologists (OBG). Materials and Methods: Participants were administered a 40-question survey, investigating the demographic properties, the knowledge on the HPV infection-vaccination and attitudes towards vaccination. Results: The study enrolled a total of 228 participants (131 pediatricians and 97 OBGs). At a rate of 99.6%, the participants agreed with the fact that the HPV infection was the most common sexually transmitted disease and 33.8% of the participants had the opinion that the HPV vaccination should be administered only in women. The lowest level of HPV vaccine recommendation was among the pediatrics specialists (59.4%, p=0.012). When asked whether they would have their daughters receive HPV vaccination, 79.5% of the participants answered favorably; this rate was 36.7% for the sons. At a rate of 59.5% of the participants thought that the HPV vaccine needed to be included in the national vaccine schedule. Most of the participants (91.6%) had the idea that reduction of the vaccine costs would increase the vaccination frequency. Conclusions: We observed that the consideration of the costs and the prejudices relating to the inefficacy of vaccination as well as the inadequate level of knowledge were involved in the physicians' resistance to HPV vaccination. We believe that the healthcare professionals should be informed adequately to overcome false beliefs, thereby ensuring success of the HPV vaccine upon inclusion in the national vaccine schedule in the future.

Background: Most northeast Thai vegetables may play roles in human health by acting as antioxidant and anticancer agents. Recent study showed that Cratoxylum formosum subsp. pruniflorum (Kurz.) Gogel. (Teawdang) could inhibit growth of liver cancer cell lines. Cervical cancer, which has human papilloma virus as its main cause, is found at high incidence in Thailand. Due to increasing drug resistance, searches for potential anticancer compounds from natural source are required. Therefore, our purpose was to evaluate the cytotoxicity of Teawdang extracts in cervical cancer cell lines. Materials and Methods: Teawdang edible parts, purchased from Khon Kaen market during July-October 2013 was extracted with organic solvent. Phenolic profiles of crude hexane (CHE), ethyl acetate (CEE), methanol (CME) and water (CWE) extracts were performed by high performance liquid chromatographic (HPLC) techniques. Their cytotoxic effects on cervical cancer cells were investigated with HPV-non infected (C-33A) and HPV-infected (HeLa and SiHa) cell lines. Results: HPLC profiles showed that all crude extracts contained caffeine, ferulic acid and resveratrol. CME and CEE had high contents of gallic acid and quercetin. Catechin was found only in CWE. Cytotoxicity test showed that CEE had the lowest IC50 on HeLa ($143.18{\pm}13.35 {\mu}g/mL$) and SiHa cells ($106.45{\pm}15.73{\mu}g/mL$). C-33A cells were inhibited by CWE ($IC50=130.95{\pm}3.83{\mu}g/mL$). Conclusions: There were several phenolic compounds in Teawdang extracts which may have cytotoxic effects on cervical cancer cell lines. Investigation of these bioactive compounds as new sources of anticancer agents is recommended.

Background: Cervical cancer is the third commonest type of cancer among women in Malaysia. Our aim was to determine the distribution of human papilloma virus (HPV) genotypes in cervical cancer in our multi-ethnic population. Materials and Methods: This was a multicentre study with a total of 280 cases of cervical cancer from 4 referral centres in Malaysia, studied using real-time polymerase chain reaction (qPCR) detection of 12 high risk-HPV genotypes. Results: Overall HPV was detected in 92.5% of cases, in 95.9% of squamous cell carcinomas and 84.3%of adenocarcinomas. The five most prevalent high-risk HPV genotypes were HPV 16 (68.2%), 18 (40%), 58 (10.7%), 33 (10.4%) and 52 (10.4%). Multiple HPV infections were more prevalent (55.7%) than single HPV infections (36.8%). The percentage of HPV positive cases in Chinese, Malays and Indians were 95.5%, 91.9% and 80.0%, respectively. HPV 16 and 18 genotypes were the commonest in all ethnic groups. We found that the percentage of HPV 16 infection was significantly higher in Chinese (75.9%) compared to Malays (63.7%) and Indians (52.0%) (p<0.05), while HPV 18 was significantly higher in Malays (52.6%) compared to Chinese (25.0%) and Indians (28%) (p<0.05). Meanwhile, HPV 33 (17.9%) and 52 (15.2%) were also more commonly detected in the Chinese (p<0.05). Conclusions: This study showed that the distribution of HPV genotype in Malaysia is similar to other Asian countries. Importantly, we found that different ethnic groups in Malaysia have different HPV genotype infection rates, which is a point to consider during the implementation of HPV vaccination.

Purpose: A wart is caused by epidermal infection with the human papilloma virus. Although wart naturally disappears in some cases, it require treatment because of pain, aesthetic problem, and the possibility of malignant change. Conventional non-surgical treatment cannot be a fundamental solution for the pain and has such disadvantages as frequent recurrence and difficulties in achieving a satisfactory outcome. A surgical procedure was performed on patients with wart and the procedure had a good outcome. Methods: We investigated the gender, age, lesion site, mean treatment duration, and presence or absence of recurrence in 21 patients with a wart within the period of January 2007 to July 2011. For local lesions, primary closure, including subcuticular suture after the excision, was performed. If the defect size was too big to do primary closure, we performed rotation flap. For wide multiple lesions, a split thickness skin graft was performed. Results: Among the 21 patients, 12 patients were male and 9 patients were female, and their mean age was 42 years (SD=17.38, range: 11~75 years). The lesion site was the foot in 10 patients, the hand in 8 patients, the face in 2 patients, and the scalp in 1 patient. The mean treatment duration was 13.5 days (SD=4.36, range: 6~15 days) for the primary closure or rotation flap, and 18.5 days (SD=2.12, range: 17~20 days) for the skin graft. 20 patients were cured without recurrence. No recurrence was observed in the patients who underwent primary closure or rotation flap. One of the two patients who underwent a skin graft of their wart that had covered their entire palm had local recurrence in part of her finger tips. Conclusion: We performed surgical procedure on recalcitrant wart. As a results, we can treat it with short treatment duration, low recurrence rate and less scarring and get high patient satisfaction.

HOX transcription factors are evolutionarily conserved in many different species and are involved in important cellular processes such as morphogenesis, differentiation, and proliferation. They have also recently been implicated in carcinogenesis, but their precise role in cancer, especially in cervical cancer (CC), remains unclear. In this work, using microarray assays followed by the quantitative polymerase chain reaction (qPCR), we found that the expression of 25 HOX genes was downregulated in CC derived cell lines compared with non-tumorigenic keratinocytes. In particular, the expression of HOXA9 was observed as down-modulated in CC-derived cell lines. The expression of HOXA9 has not been previously reported in CC, or in normal keratinocytes of the cervix. We found that normal CC from women without cervical lesions express HOXA9; in contrast, CC cell lines and samples of biopsies from women with CC showed significantly diminished HOXA9 expression. Furthermore, we found that methylation at the first exon of HOXA9 could play an important role in modulating the expression of this gene. Exogenous restoration of HOXA9 expression in CC cell lines decreased cell proliferation and migration, and induced an epithelial-like phenotype. Interestingly, the silencing of human papilloma virus (HPV) E6 and E7 oncogenes induced expression of HOXA9. In conclusion, controlling HOXA9 expression appears to be a necessary step during CC development. Further studies are needed to delineate the role of HOXA9 during malignant progression and to afford more insights into the relationship between downmodulation of HOXA9 and viral HPV oncoprotein expression during cercical cancer development.
