Sexually transmitted infection as a cause of anal cancer
Article Abstract:
Anal cancer may be caused by the sexually-transmitted human papillomavirus (HPV). HPV causes genital warts and is already strongly associated with cervical cancer. In a telephone survey of 417 patients with anal cancer and 1,088 without the disease in Denmark and Sweden, histories of sexual promiscuity, venereal disease, and anal intercourse were more common in those with anal cancer. Eighty-four percent of the anal-cancer tumors tested contained one of the high-risk types of HPV. This strong association, and previous research, implicate HPV as a probable cause of anal cancer, which means anal cancer may be preventable.

Effects of family history and place and season of birth on the risk of schizophrenia
Article Abstract:
Environmental factors may be a more important risk factor for schizophrenia than a family history. Researchers analyzed the records of 2,669 schizophrenics among 1.75 million people in Denmark. Having a family member with schizophrenia increased the risk about 7 to 9 times depending on the family member. However, only 5.5% of the patients had a family history of schizophrenia. Ten percent had been born in the early spring, the season of highest risk. Thirty-five percent had been born in an urban area. Although genetic factors cannot be completely excluded, environment factors appear to play a bigger role.
