BACKGROUND Epidemiological evidence suggests lack of neonatal circumcision as the strongest risk factor for penile cancer, but the role of sexually transmitted diseases in the etiology of penile cancer has remained unclear. PURPOSE To further clarify risk factors for penile cancer, we examined the role of circumcision, personal characteristics and habits(More)
To elucidate the risk factors for anal cancer, we interviewed and obtained blood specimens from 148 persons with anal cancer and from 166 controls with colon cancer in whom these diseases were diagnosed during 1978-1985. We found that in men, a history of receptive anal intercourse (related to homosexual behavior) was strongly associated with the occurrence(More)
A population-based case-control study was conducted in western Washington state to examine the relations between infection with human papilloma viruses (HPV), herpes simplex viruses (HSV), and risk of oral squamous cell cancer in men. Interviews were completed on 131 oral cancer cases diagnosed between January 1985 and December 1989 and 136 controls(More)
The association between cigarette smoking and cervical cancer has been demonstrated in numerous prior studies. As part of population-based case-control studies of cancers of the vulva, vagina, cervix, anus, and penis in relation to infection with human papillomavirus, conducted in western Washington State and the province of British Columbia from the mid(More)
To study the association of human papillomavirus (HPV) infection with anal cancer, we examined tissue specimens from 126 patients with malignant lesions of the anal skin or mucosa. The patients were enrolled in a population-based, case-control study of ano-rectal cancer which is being conducted in the state of Washington and the Province of British(More)
BACKGROUND Most studies report that a single induced abortion does not increase risk for delivering a low birth weight infant in a subsequent pregnancy. However, the effect of multiple abortions has not been adequately evaluated. METHODS This relationship was studied in 6541 White women who delivered their first child between 1984 and 1987. We compared(More)
The relationship of cull rate to age was investigated retrospectively in dairy cows with and without antibodies to bovine leukemia virus (BLV). Banked sera from eight annual herd tests on one 200-cow herd were tested for presence of BLV antibodies by agar-gel immunodiffusion using the Mr 51,000 glycoprotein antigen of BLV. Age-specific cull rates were(More)
Bibliographic metadata standards are a longstanding mechanism for Digital Libraries to manage records and express relationships between them. As digital scholarship, particularly in the humanities, incorporates and manipulates these records in an increasingly direct manner, existing systems are proving insufficient for providing the underlying(More)
