Background and Aims: Ovarian cancer is one of most common causes of cancer related women's mortalities. Human papilloma virus is a known factor concerning cervical cancer but its role in causing ovarian cancer is not yet verified. A few studies also identified HPV DNA in ovarian carcinoma tissues. However, some studies did not detect HPV DNA in ovarian carcinoma tissues. In this article, we investigated the potential role of high risk HPVs in the ovarian epithelial carcinoma.
Methods: Fifty archived epithelial ovarian cancer paraffin blocks were collected. Then, 30 non-malignant ovarian blocks used as control. These samples were histopathologically were confirmed by a pathologist and the proper blocks for DNA extraction and PCR were sorted. PCR was conducted deploying highly specific primers for high-risk types of HPV (18 and 16) according to the instructions of manufacturer company.
Results: High-risk oncogenic sequences were identified in 4 (5%) of the 80 studied samples. Of the 4 HPV positive cases, there was 1 case with normal tissue, 1 case of mucinous cyst adenocarcinoma, and 2 cases of serous cyst adenocarcinoma
Conclusion: Surprisingly, our findings could not support any association between high-risk oncogenic human papilloma virus (18 and 16) and malignant ovarian epithelial cancer. Therefore, that HPV is highly unlikely to play any causal role in the pathogenesis of epithelial ovarian neoplasia.

Background and Objective: Ischemic heart disease (IHD) following atherosclerosis is the most common cause of cardiac deaths world wide. We aimed to investigate the pathologic features of atherosclerosis in non cardiac death cases to have an estimate of atherosclerosis prevalence in Mashad (North east of Iran). Patients and Methods : This descriptive (cross sectional) study was done, during October 2007 – March 2008, on 80 cadavers from 11 to 50 years old who had died of non cardiac causes and had no history of cardiac disease. After autopsy in forensic medical center, coronary arteries were removed and examined for atherosclerotic plaques. In case of a definite or suspicious lesion, microscopic slides were also prepared. Otherwise, three random slides from each branch of coronary arteries were studied by a pathologist. Results: We found that 73.1% of men and 61.5% of women had at least one fibrofatty or advanced plaque in major coronary arteries. Atherosclerosis in 41.8% of men and 30.8% of women was in advanced form. Frequency of advanced atherosclerotic plaques progressed with age reaching a maximum of 78.5% by the age of 41-50 years. In addition, prevalence of plaques suddenly increased after second decade of life. Atherosclerotic plaques were most commonly found in left anterior descending artery (60%) followed by right coronary (50%) and left circumflex (42.5%) arteries. Conclusion: This study showed an unexpectedly high prevalence of atherosclerosis in this population. It highlights the importance of cardiovascular risk factor screening from early ages of third decade.
