Cancer risk in relatives of patients with common colorectal cancer
Article Abstract:
First-degree relatives of patients with common colorectal cancer may have a higher risk of developing this type of cancer than other individuals. A study compared the incidence of colorectal cancer among 7,493 first-degree relatives and 1,015 spouses of 523 colorectal cancer patients and 523 healthy individuals. The risk of developing colorectal cancer was twice as high for parents and siblings of colorectal cancer patients than for those of healthy individuals. This risk was higher for individuals with two first-degree relatives with colorectal cancer than for those with only one. The cumulative risk was higher among first-degree relatives of patients who were under 45 years old at the time of diagnosis. First-degree relatives of colorectal cancer patients should consider having routine screening for colorectal cancer beginning at the age of 40 years old.

Lessons learned from attempts to establish the blind in placebo-controlled trials of zinc for the common cold
Article Abstract:
All researchers who conduct placebo-controlled trials should ask the patients in the trial to guess whether they are receiving the drug or the placebo. A placebo is an inactive substance that supposedly looks and tastes exactly like the drug. Asking patients to guess which one they're receiving would detect any differences.

Zinc acetate lozenges to treat the common cold
Article Abstract:
Zinc lozenges may substantially shorten the duration of a cold, according to a study of 50 people. Those who took zinc lozenges within 24 hours of symptoms got over the cold in about 4 days, compared to 8 days in the group that took a placebo, or inactive substance.
