It has been reported recently that oral human papillomavirus (HPV) infection is associated with oropharyngeal squamous cell carcinomas. The aim of this study was to determine the prevalence of HPV infection and HPV types in the oral cavity and cervix of female sex workers in Japan. Oral and cervical swabs were taken from 196 female sex workers who visited a clinic for regular medical checkups i...

BACKGROUND MicroRNAs play important roles in the development of human cancers. This case-control study is to evaluate the roles of the polymorphisms in pre-miRNAs on risk of oral cancer in a Chinese population. METHODS The genotypes of three polymorphisms were determined in 340 patients with oral squamous cell cancer and 340 healthy controls who were frequency matched for age and sex. Odds ra...

METHODS Hospital-based case-control study in the metropolitan area of São Paulo, southeastern Brazil, from 1998 to 2002. A total 309 patients with squamous cell carcinoma of the mouth and the pharynx and 468 controls matched by sex and age were included in the study. Cases were recruited in seven re...

Oral squamous cell carcinoma is an important malignancy of epithelial origin with high rate of morbidity and mortality. While tobacco and alcohol are the primary risk factors; other factors such as microorganisms, chronic irritation and sex hormones along with underlying genetic factors may also contribute to its pathogenesis. The role of sex hormones like estrogen, progesterone and testosteron...

Oral health disparities have exacerbated since the popularity of chewable tobacco among the general population in Pakistan. Karachi South ranks second in the incidence of oral cancer and this frequency is steadily rising. Several molecular studies have shown a link between the use of chewable tobacco products and oral submucosal fibrosis. Oropharyngeal cancer, is being driven by HPV is now well...

The urinary amino acid profiles of 79 young women and 72 young men were studied with an automated highpressure amino acid analyzer. A nonparametric statistical analysis was applied for detecting profile differences related to sex and other variables. A strong sex-related pattern was confirmed and its power for sex determination was evaluated. For the women, profile differences related to the us...

Variations of baseline plasma concentrations of creatine kinase (CK), heat shock protein 70 (HSP70), and interleukin 6 (IL-6) have been reported. We report categorical associations which may influence these protein levels. Methods. Blood was harvested for DNA and plasma protein analysis from 567 adults. Mean protein levels of CK, HSP70, and IL-6 were compared by sex, ethnicity, genetic variants...

In 2008 there were 11682 cases of oral cancer in the United Kingdom; this is 16.41/100000 population, and 3.7% of all cancers. Ethnic coding of these data is poor, and so databases were combined to report rates for the incidence of oral cancer in South Asians compared with those among other ethnic groups in West Yorkshire, 2001-2006. A total of 2157 patients with oral cancer were identified in ...

BACKGROUND This study was conducted to ascertain the feasibility of using rapid oral fluid testing as an alternative HIV testing method in China. METHOD This is a mixed-method study among men who have sex with men (MSM), female sex workers (FSW) and VCT clients, conducted in 4 cities in Shandong Province.
