why do tetanus shots hurt so much

The tetanus vaccine is a toxoid, meaning that what they inject is not living attenuated bacteria, but rather the toxin that Clostridium tetani produces. This toxin is neurotoxic in that it causes intense muscle spasms (think the classic lock-jaw of tetanus). This is what kills people who get tetanus (tetany is medical-talk for sustained muscle contraction). The toxoid in the vaccine causes these muscle spasms and pain, but since there is no new production of toxin, your body recognizes, fights off, and then builds immunity to the disease. ...

why do my teeth keep breaking off

Some of my patients do seem to break a number of their teeth. There are probably a number of factors in involved. First lets look at back teeth that break or crack. Often the teeth that break have fillings that undermine the existing tooth structure. Even a small filling placed close to a marginal ridge ( the mesial or distal of the tooth) can make a crack more likely to develop. Many of these teeth really should have onlays or crowns placed to protect them. Another factor is the occlusion and frequency of night time clenching and bruxism ( many people do this at times while sleeping). Patients that have worn their teeth flatter so that there posterior tooth surfaces meet quite broadly during excursions often apply more force to their posterior teeth. These are people who have "cow bites"

why do people think animal testing is right

Research involving animals has come a long way since Pavlov made his dogs drool. Animal research today is regulated rigorously and is far more humane and efficient. Still, many people associate animal testing with bunny rabbits wearing more mascara than Tammy Faye Baker, or monkeys chained to rocks and zapped with Tasers to test whether being chained to rocks and zapped with Tasers causes cancer. Such thinking led to the firebombing on Feb. 5 of the home of Edythe London, a well-respected scientist at the University of California, Los Angles, whose research on nicotine addiction involves a variety of animals, including monkeys. It s unclear whether the perpetrators of this violent act ever get sick and seek medical advice, because nearly every medical advance in the last century as well

why is second hand smoke more dangerous

What is secondhand smoke? Secondhand smoke is the combination of smoke from a burning cigarette and smoke exhaled by a smoker. There are two types of secondhand smoke; side stream smoke comes directly from the burning tobacco product, and mainstream smoke is the smoke that the smoker inhales. The smoke that burns off the end of a cigarette or cigar actually contains more harmful substances than the smoke inhaled by the smoker, as there is no filter it must pass through. How does secondhand smoke affect non-smokers? If you are a non-smoker but are exposed to secondhand smoke on a regular basis, your body will still absorb nicotine and other harmful substances.

* Apparently Michele Lingre is not a child psychologist, educator, media analyst or other type of "expert. " Perhaps that is why she displayed such uncommon common sense in identifying what so many seem unable--or unwilling--to acknowledge: Television viewing has profound affects on children. (Let's not forget the same is true for teen-agers and adults, but because their brains are more fully developed, the magnitude of the effect is minuscule by comparison. ) In her Jan. 9 commentary, "Turning Off TV Gives Child a New View of Life," Lingre points to the core issue: Television watching as an activity should be the focus of the discussion. Our societal debate regrettably has been refocused such that we now consider only the effects of content, specifically sex and violence--and of late
