...tend to worry a lot more about the health hazards of anal sex than oral. Everybody knows, after all, that it's much easier for the virus that causes AIDS to cross the lining of the rectum than to infect someone through the mouth. Or is it? The surprising results of a study on rhesus monkeys published last week in Science not only suggest otherwise but also underscore how little scientists know about how, at the microscopic level, HIV spreads from one person to the next...
...what do these findings have to say about people? Exact correlations are impossible to make. SIV and HIV, although similar in many respects, are different viruses. And the scientists did not try to create the tiny tears in the lining of the rectum like those that are produced during anal sex and that increase the chance of HIV infection in humans. But generally speaking, the results support the idea that the number of HIV particles found in an infected man's semen--though not in the saliva--is sufficient to be passed on through the mouth or throat. One likely...
...first time, the government is urging everyone over age 50 to have regular screenings for colon and rectal tumors. Annual tests for blood in the stool and periodic exams, with a scope, of the rectum and colon are suggested...
...list of alleged crimes (usually against children) is long and literally unbelievable. It comprises everything from bizarre rituals involving "magic rooms" and robots (R2D2 makes an appearance in one) to coprophagy and rape with sharp objects (in one case, a "sword in the rectum"). Fantastic physical traumas (e.g., the sword) yield not a shred of physical evidence. One child said her teacher had turned her into a mouse. For a myriad of such offenses, New Jersey preschool teacher Margaret Kelly Michaels was given 47 years. (Her conviction was overturned in 1993--after she had served five...
...there is a single leading reason why middle-age men dread going to the doctor, it is the prostate examination. Routinely recommended for those 50 and over, the procedure calls for a physician to insert a gloved finger into the rectum to probe the chestnut-size prostate gland, which is near the bladder and produces some of the fluids in semen. But however uncomfortable and embarrassing the exam may be, it could be a lifesaver. The rate of prostate cancer in the U.S. has been steadily rising over the past several years. It strikes 1 in 11 American males...
