An increasing number of cancer patients who receive chemotherapy now do so at home, with the click of a pill bottle each day rather than the drip of an IV medicine that must be delivered in a doctor's office or hospital. http://phys.org/news162740105.html Medicine & Health Thu, 28 May 2009 14:35:40 EST news162740105 Human papillomavirus (HPV) is a group of viruses that includes more than 100 different strains or types and is the most common sexually transmitted virus. The American Social Health Association (ASHA) reports that 75 percent or more of sexually active Americans will contract HPV sometime in their lives. HPV is most commonly attributed to causing cervical cancer and genital warts, but did you know HPV also causes oral cancer? http://phys.org/news154200457.html Medicine & Health Wed, 18 Feb 2009 17:28:37 EST news154200457 Human calmodulin-like protein (CLP) is found in many cell types including breast, thyroid, prostate, kidney, and skin. The protein can regulate many cell activities and has a highly specific expression. Gaining an understanding about the expression of CLP in oral epithelial cells and its possible downregulation (or lack of production) in cancer may be a potentially valuable marker in early detection of oral cancer. A new study in the Journal of Prosthodontics found that CLP is expressed in normal human oral muscosal cells and that downregulation of this protein may be an indicator of malignancy or cancer. http://phys.org/news150557236.html Medicine & Health Wed, 07 Jan 2009 13:27:16 EST news150557236 Worldwide, more than 500,000 new cases of cancer of the mouth are diagnosed each year. The majority of these cancers are found too late, causing many people to die within five years of finding out they have cancer. There exists much information addressing issues related to the patient who has undergone surgery or chemotherapy but little information related to early diagnosis and referral. In a new article in the Journal of Prosthodontics, researchers led by Michael A. Siegel, DDS, MS, FDS, RCSEd, describe the epidemiology of oral cancer and the diagnostic tools currently available to prosthodontists to ensure that their patients are diagnosed at the earliest possible time. http://phys.org/news148134034.html Medicine & Health Wed, 10 Dec 2008 12:20:34 EST news148134034
