New Hope for Motivated Quitters
Thu, July 20, 2006 at 04:27AM Most smokers trying to stop need some help from medication. Apart from the nicotine patch, the mainstay in recent years has been bupropion, which was originally used extensively as an antidepressant (Wellbutin® for depression, Zyban® for help quitting smoking). A recent issue of the Journal of the American Medical Association has published three clinical studies of varenicline, a new drug being developed by Pfizer Inc.
In the first two studies, varenicline was compared with bupropion and placebo for 12 weeks, with 40 to 52 weeks of non-drug follow-up. Varenicline was roughly twice as likely as bupropion to help people quit for at least the last 4 weeks of the 12 weeks’ treatment, and bupropion was twice as likely as placebo to achieve this. During the follow-up periods (weeks 12 through 40) smoking abstinence persisted for 22.5% with varenicline, compared with roughly 15% on bupropion and 10% on placebo. The third study examined the effect of varenicline given for an additional 12 weeks after the original 12, as maintenance therapy. Results were similar to those in the other studies.
About 30% of participants in these studies reported nausea with varenicline, significantly more than with bupropion or placebo. At first sight these results may not seem as wonderful as one might have hoped. But they do show effectiveness in a condition that’s notoriously difficult to influence, and the longer follow-up results are quite good. We are glad that FDA has approved this drug, so that smokers have another weapon in their war with the weed.

The bleeding may possibly be caused by scratching. Skin bumps and itching with pus formation possibly indicate some type of skin infection. Aging reduces the capacity of the skin to moisturize itself, so the skin becomes dry. Dry skin is one of the major causes of itchiness in aging skin: the pattern can vary considerably from person to person. What's more, signs and symptoms of dry skin depend on age, health status, where on the body it occurs, the amount of time spent outdoors, and the cause of the problem. Other causes of itchy skin often require the attention of a dermatologist. Elderly skin is sometimes more sensitive to clothing fabrics (especially wool), soaps and detergents, and other items encountered in everyday living. Identification of the sensitizing agents and limiting exposure to them may reduce the itchiness. Allergies to a host of indoor and outdoor agents may cause itching. Some medications cause itchiness as a side effect. Severe itching as well as itching that does not respond to moisturizing should be evaluated by a dermatologist.
Also, as people age, the skin becomes thinner and fat padding under the skin is lost. Thus, blood vessels are less protected from injury. An injury inflicted by mild trauma - for example, bumping against a table or being hit by a tennis ball - may result in a substantial bruise. In some instances, bruising may be an indication of an underlying condition. Bruises that appear for no apparent reason may indicate a bleeding disorder. Anti-clotting medications may cause bleeding under the skin. To help prevent these knocks, extra protection should be worn on limbs, especially when outside, gardening etc. Good eyesight can also help prevent bumping into objects.
