Gout is a kind of arthritis. It can cause an attack of sudden burning pain, stiffness, and swelling in a joint, usually a big toe. These attacks can happen over and over unless gout is treated. Over time, they can harm your joints, tendons, and other tissues. Gout is most common in men.
An attack of gout can occur suddenly, often waking you up in the middle of the night with the sensation that your big toe is on fire. The affected joint is hot, swollen and so tender that even the weight of the sheet on it may seem intolerable.
Gout is caused by too much uric acid in the blood (hyperuricemia). The exact cause of hyperuricemia sometimes isn’t known, although inherited factors (genes) seem to play a role.
Uric acid may form crystals that build up in the joints. This causes the pain and other symptoms.
Fortunately, gout is treatable, and there are ways to reduce the risk that gout will recur.

The Food and Drug Administration (FDA) has launched its first public health education campaign—”The Real Cost”—to prevent and reduce tobacco use among at-risk young people ages 12-17. Mitch Zeller, J.D., director of FDA’s Center for Tobacco Products (CTP), explains why the agency is undertaking this effort and how it will work.
Q: Why has FDA launched a youth tobacco prevention campaign?
A: Tobacco use is the leading preventable cause of disease, disability, and death in the United States, responsible for more than 480,000 deaths each year. But the consequences of tobacco use are not limited to adults. Tobacco use is almost always initiated and established during adolescence. More than 3,200 young people under age 18 smoke their first cigarette every day in the United States—and another 700 become daily smokers. FDA sees a critical need for targeted efforts to keep young people from starting on this path. Reducing the number of teens who start smoking will diminish the harmful consequences that tobacco use has on the future health of our country. “The Real Cost” campaign ads will run nationwide beginning on February 11.
Q: Tell us more about the campaign and its target audience.
A: As FDA’s first campaign to prevent youth tobacco use, “The Real Cost” targets the 10 million young people ages 12-17 who are open to trying smoking or who have already smoked between one puff and 99 cigarettes in their lifetime. These youths share important characteristics that put them at risk for tobacco use. They are more likely to live chaotic, stressful lives due to factors such as socioeconomic conditions; be exposed to smoking by friends and family; and use tobacco as a coping mechanism or a way to exert control or independence. Additionally, many at-risk youths who experiment with cigarettes do not consider themselves smokers, do not believe they will become addicted, and are not particularly interested in the topic of tobacco use. We want to make these teens hyperconscious of the risk from every cigarette by highlighting consequences that young people are concerned about, such as loss of control due to addiction and health effects like tooth loss and skin damage.
Q: How is FDA going to implement the campaign?
A: We’ll use paid advertising to surround teens with the “The Real Cost” message. This includes advertising on TV, radio and the Internet, as well as in print publications, movie theaters and outdoor locations like bus shelters. We plan to reach more than 9 million youths with our messages as many as 60 times a year.
Q: How will FDA know if the campaign is working?
A: FDA is going to evaluate the campaign over time to see if it’s effective. We’re going to conduct a longitudinal study, meaning that we are going to try to follow the same 8,000 youths over a two-year period. We will assess key changes in their tobacco-related knowledge, attitudes, beliefs and behaviors over several years to measure the impact and effectiveness of the campaign. In-person, baseline data collection started in November 2013 in 75 media markets across the country. Ultimately, we want to see if exposure to the campaign is associated with a decrease in smoking among youth.
Q: Is this campaign funded by U.S. tax dollars?
A: No. User fees collected from the tobacco industry fund all FDA’s tobacco-related activities, including educating the public about the harms of tobacco use.
Q. Is this FDA’s only youth tobacco prevention campaign?
A: This initial FDA effort is the first of several distinct youth-focused campaigns being launched in the next two to three years. Other youth tobacco prevention campaigns will target additional audiences such as African American, Hispanic, Asian/Pacific Islander and American Indian/Alaskan Native youths, rural youths, and lesbian, gay, bisexual and transgender youths.
Q: How can I get involved?
A: FDA’s goal is to keep “The Real Cost” campaign authentic through a peer-to-peer approach. The campaign website and social channels are intended for teens. We recommend that adults use and share the materials on FDA’s resource page, including campaign information and customizable resources such as posters, postcards and campaign flyers. All materials are available for free download and many will soon be available for ordering through the campaign’s clearinghouse. Stakeholders who work with youth audiences can help extend the campaign by encouraging teens to share campaign messages with their peers, or by sharing our resources with other youth-focused organizations.

Regardless of the cause, neuropathy is associated with characteristic symptoms. Although some people with neuropathy may not have symptoms, certain symptoms are common. The degree to which an individual is affected by a particular neuropathy varies.
Damage to the sensory nerves is common in peripheral neuropathy. Symptoms often begin in the feet with a gradual onset of loss of feeling, numbness, tingling, or pain and progress toward the center of the body with time. The arms or legs may be involved. The inability to determine joint position may also occur, which can result in clumsiness or falls. Extreme sensitivity to touch can be another symptom of peripheral neuropathy. The sensation of numbness and tingling of the skin is medically known as paresthesia.
The loss of sensory input from the foot means that blisters and sores on the feet may develop rapidly and not be noticed. Because there is a reduced sensation of pain, these sores may become infected and the infection may spread to deeper tissues, including bone. In severe cases, amputation may be necessary.
Certain prescription medications have been shown to bring relief for those with neuropathy. In severe cases, a combination of medications may be necessary. These drugs may be effective for lessening pain or joint damage and deformities associated with neuropathy, but they should be used with caution because there is some concern that these drugs may worsen nerve injury.
Neuropathy remedies are among those being considered by patients who have had no success with, or do not want the side effects of, pharmaceutical drugs. Natural neuropathy remedies can be safe and effective and can work to promote overall health. Remedies range from herbal and homeopathic to nutritional.

Making healthy food choices is one important thing you can do to reduce your risk of heart disease — the leading cause of death of men and women in the United States.
According to the American Heart Association, about 80 million adults in the U.S. have at least one form of heart disease—disorders that prevent the heart from functioning normally—including coronary artery disease, heart rhythm problems, heart defects, infections, and cardiomyopathy (thickening or enlargement of the heart muscle).
Experts say you can reduce the risk of developing these problems with lifestyle changes that include eating a healthy diet. But with racks full of books and magazines about food and recipes, what is the best diet for a healthy heart?
Food and Drug Administration nutrition expert (FDA’s) Barbara Schneeman says to follow these simple guidelines when preparing meals:
- Balance calories to manage body weight
- Eat at least 4.5 cups of fruits and vegetables a day, including a variety of dark-green, red, and orange vegetables, beans, and peas.
- Eat seafood (including oily fish) in place of some meat and poultry
- Eat whole grains—the equivalent of at least three 1-ounce servings a day
- Use oils to replace solid fats.
- Use fat-free or low-fat versions of dairy products.
The government’s newly released “Dietary Guidelines for Americans 2010” also says Americans should reduce their sodium intake. The general recommendation is to eat less than 2,300 mg. of sodium a day. But Americans 51 or older, African-Americans of any age, and people with high blood pressure, diabetes, or chronic kidney disease should restrict their intake to 1,500 mg. The government estimates that about half the U.S. population is in one of those three categories.
Packaged and Restaurant Food
Schneeman, who heads FDA’s Office of Nutrition, Labeling, and Dietary Supplements, says one way to make sure you’re adhering to healthy guidelines is by using the nutrition labels on the packaged foods you buy.
“Product labels give consumers the power to compare foods quickly and easily so they can judge which products best fit into a heart healthy diet or meet other dietary needs,” Schneeman says. “Remember, when you see a percent DV (daily value of key nutrients) on the label, 5 percent or less is low and 20 percent or more is high.”
Follow these guidelines when using processed foods or eating in restaurants:
- Choose lean meats and poultry. Bake it, broil it, or grill it.
- In a restaurant, opt for steamed, grilled, or broiled dishes instead of those that are fried or sautéed.
- Look on product labels for foods low in saturated fats, trans fats, and cholesterol. Most of the fats you eat should come from polyunsaturated and monounsaturated fats, such as those found in some types of fish, nuts, and vegetable oils.
- Check product labels for foods high in potassium (unless you’ve been advised to restrict the amount of potassium you eat). Potassium counteracts some of the effects of salt on blood pressure.
- Choose foods and beverages low in added sugars. Read the ingredient list to make sure that added sugars are not among the first ingredients. Ingredients in the largest amounts are listed first. Some names for added sugars include sucrose, glucose, high fructose corn syrup, corn syrup, maple syrup, and fructose. The nutrition facts on the product label give the total sugar content.
- Pick foods that provide dietary fiber, like fruits, beans, vegetables, and whole grains.
