Skin allergies and contact dermatitis Archive

Cellulitis, a skin infection that often occurs on the lower leg, develops when bacteria enter the body through a cut, bite, or other wound. A new study shows key aspects of healing typically occur within 10 days of treatment, but symptoms can linger for some time after that.

White spots on fingernails are common and have many possible causes. These include minor trauma to the fingers, wearing nail polish for prolonged periods, fungal infections, low iron levels, kidney disease, or liver cirrhosis.

People should do a full-body skin check-up every three to six months to identify abnormalities that may be early signs of skin cancer or other skin problems. Write down the date of the self-exams, record any issues like new or questionable moles, sores, painful or itchy spots, raised or firm bumps, dark flaky patches, and unusual freckles. Include the exact locations of these skin issues and take photos for reference. After six to eight weeks, see a dermatologist if they have not improved, have changed color or size, have become painful, or easily bleed.

A common form of eczema called atopic dermatitis can interfere with daily activities. There are a number of prescription creams available to ease this chronic skin condition, but some are more effective than others, and a recent study compared them.

There are a number of skin conditions that can affect the vulva. Sometimes the products a woman uses every day can irritate the skin or provoke an allergic reaction.

Skin lumps or bumps occur on or just under the skin. Most are harmless. Aside from basal and squamous cell skin cancers, most other skin lumps are epidermal cysts or lipomas. Other growths include cherry angiomas, dermatofibromas, keloids, and very rarely cancerous tumors called sarcomas. People should seek medical attention for any lump appearing near lymph nodes, which sometimes signals cancer. A doctor should also evaluate growths that grow quickly, bleed, look infected, or feel painful. Most skin lumps or bumps don't need treatment.

Dry skin and athlete's foot affect many men. There are several treatment options for both conditions, and steps you can take to prevent them from occurring or returning.

News coverage of a case of leprosy in central Florida may have made it seem like there is an increased threat the disease would spread. Misconceptions about this disease have persisted for a long time, but the facts are reassuring.

An array of "menopause skin care" products joined the beauty market in recent years. Some contain virtually the same active ingredients as "anti-aging" skin products. Falling estrogen levels during the menopause transition can lead to dryness and sagging. Broad-spectrum sunscreen, moisturizers, and other products can help offset these skin changes, but not prevent or cure them. Women should examine a product's ingredients to determine if a "menopause" version is truly different from a standard "anti-aging" version.

There's no time to lose when someone suffers a burn. For a minor burn on a small area of skin, run cool water over it for 20 minutes to help limit damage, and then apply petroleum jelly or antibiotic cream and cover the burn with a bandage. If a blister develops, dab antibacterial cream on it, cover it with a bandage, and get to a doctor as soon as possible. Second-degree burns that are large or involve the face, hands, feet, or genitals, and all third-degree burns, warrant a call to 911.
