Pernicious anemia
Article Abstract:
The most prevalent cause of vitamin B12 deficiency is pernicious anemia. Pernicious anemia develops after many years from a chronic stomach condition, type A atrophic (autoimmune) gastritis. Parietal cells in the stomach are destroyed by an autoimmune disorder. These cells produce intrinsic factor necessary for the body to utilize the vitamin. This vitamin B12 deficiency can result in neurological complications including memory loss and psychotic illness as well as the typical macrocytic, or large red cell, anemia. Immediate treatment with injections of vitamin B12 may correct the anemia and neurological complications.

Natural history of cervicovaginal papillomavirus infection in young women
Article Abstract:
Cervical infection with the human papillomavirus (HPV) appears to be common in sexually active young women but many cases may resolve without treatment. Researchers followed 608 college women for three years, taking cervical samples and lifestyle surveys every six months. At some time during the study, 60% of the women had a cervical HPV infection. Many of the infections resolved spontaneously, but those caused by HPV linked to cervical cancer often lingered. Young black and Hispanic women who had many sex partners had a high risk of HPV infection.

Pernicious papillomavirus infection
Article Abstract:
Research has clearly shown a link between sexual activity and cervical cancer. The most likely transmissable agent is human papillomavirus (HPV). HPV has been as strongly linked to cervical cancer as smoking has been to lung cancer. In addition, HPV has been detected in over 90% of tumor samples from women with cervical cancer. A 1999 study found HPV in cervical biopsies of 77% of the women with cervical cancer but only 4% of the women who did not have cervical cancer. However, it may not be feasible to screen all sexually active women.
