Problem 3da study published inThe Journal of Dentistry in2006, for example, a team of dentist recruited 73adult volunteers and randomly split them into groupsthat had one of four substances applied to the gumsjust above the maxillary canine teeth: a clove gel,benzocaine, a placebo resembling the clove gel, or aplacebo resembling benzocaine. Then, after fiveminutes, they compared what happened when thesubjects received two needle sticks in those areas.Not surprisingly, the placebos failed to numb thetissue against the pain, but the clove and benzocaineInapplications numbed the tissue equally well.This experiment was single blind. Why was thisprecaution necessary?

Experiments can be performed single-blind or double-blind depending upon the need of the experiment…

In the 1940s, the U.S. government was looking for a solution to a medical problem: the prevalence of sexually transmitted diseases (STDs) among soldiers. Several now-infamous government-funded studies used human subjects to research common STDs and treatments. In one such study, American researchers intentionally exposed more than 1300 human subjects in Guatemala to syphilis, gonorrhea, and chancroid to determine the ability of penicillin and other antibiotics to combat these diseases. Subjects of the study included Guatemalan soldiers, prisoners, prostitutes, and psychiatric patients—none of whom were informed that they were taking part in the study. 1) What type of Epidemiological Study does this fall under; Descriptive, Analytical, Retrospective, Observational, or Prospective. 2) Please explain why this study was ethical or unethical. 3) We discussed a similar tragic but famous study that happened in the U.S. (it took place in Alabama) in one of our lectures.

What do you think about the longitudinal NIH-funded Bogalusa Heart Study, created by cardiologist Gerald Bevenson in 1972? This study is following 16,000 who started in childhood and are now adults (40 years thus far). Researchers have looked at several things, on those living, as well as performing autopsies on 560 of these individuals who died since then (of accidental death or otherwise). 20% of autopsied children had plaques (fat deposits) in their coronary arteries, making this the first study of its kind to establish heart disease can exist in children, and those who were obese as children were likely to remain so in adulthood, as opposed to only 7% becoming obese who were not so in childhood.

[q4 discussion #2] In a study investigating the effects of new anti-itch cream, participants with minor skin rashes were randomly divided into one of three groups. In the first group, participants received a new anti-itch cream that contained 3% hydrocortisone. In the second group, the participants received the standard cream available over-the-counter which contains 1% hydrocortisone. The third and final group members received a cream that contained 0% hydrocortisone. The participants did not know to which group they were assigned. Participants used the cream for three days to relieve itching symptoms caused by rash. After three days, each participant’s rash was examined to determine if itching symptoms subsided. If this was not the case, the participant was provided with the standard treatment, which is known to relieve itching. Is this a single or double blind study?
