Medical Conditions
Psoriasis cannot be cured but it can be treated successfully, sometimes for months or years at a time and occasionally even permanently. Treatment depends on the type, severity and location of psoriasis; the patient’s age, medical history and lifestyle; and the effect the disease has on the patient’s general mental health. The most common treatments are topical medications, phototherapy, photochemotherapy (PUVA), and oral or injectable medication.
Eczema is a term used to describe a group of inflamed skin conditions that result in chronic itchy rashes. About 15 million people in the U.S. suffer from some form of eczema, including 10-20 percent of all infants. Symptoms vary from person to person but often include dry, red, itchy patches on the skin which break out in rashes when scratched. Treatment involves the restriction of scratching, use of moisturizing lotions or creams, cold compresses and nonprescription anti-inflammatory corticosteroid creams and ointments; prescription corticosteroid medication, antibiotics to combat infection, or sedative antihistamines; phototherapy; or, for severe cases, drugs such as cyclosporine A. Acne is the term for the blocked pores, pimples, and deeper lumps that appear typically on the face, neck, chest, back, shoulders and upper arms. Seventeen million Americans currently have acne, making it the most common skin disease in the country. While it affects mostly teenagers, adults of any age can have it. Acne is not life-threatening, but it can cause scarring and emotional distress. The choice of treatment depends on the type and severity of lesions, skin type and the patient’s age and lifestyle. On average results are visible in a few weeks. A rash is a change in the skin’s color or texture. Simple rashes are called dermatitis, which means the skin is inflamed or swollen. Other common rashes include eczema, psoriasis, impetigo, shingles, chicken pox, measles, scarlet fever, insect bites and those caused by medical conditions such as lupus or rheumatoid arthritis. A dermatologist is usually able to identify the rash by looking at it and asking about accompanying symptoms. Mild rashes can often be treated with simple home care practices such as avoiding soaps and bathing in warm water. Others may require moisturizing creams, prescription medications or more extensive treatment. Skin cancer refers to the abnormal, uncontrolled growth of skin cells. The most common skin cancers are basal cell carcinoma (affecting cells in the lowest layer of the epidermis) and squamous cell carcinoma (affecting cells in the middle layer of the epidermis). A rarer but more dangerous skin cancer is melanoma, the leading cause of death from skin disease. Risk factors for developing skin cancer include pale skin, family history of melanoma, being over 40 years old, and regular sun exposure. Skin cancers vary in shape, color, size and texture, so any new, changed or otherwise suspicious growths or rashes should be examined immediately by a physician. Early intervention is essential to preventing the cancer from spreading. Rosacea is a chronic skin disease affecting about 14 million Americans that causes redness and swelling on the face and also occasionally the scalp, neck, ears, chest, back and/or eyes. Although it can affect anyone, rosacea typically appears in light-skinned, light-haired adults aged 30-50. Symptoms range from red pimples, lines and visible blood vessels to dry or burning skin and a tendency to flush easily. Many people find that the emotional effects of rosacea – i.e. low self-confidence and avoidance of social situations – are more difficult to handle than the physical ones. It is not yet known what causes rosacea and the disease is not curable, although it can be treated. Early detection and intervention are essential to achieve the most effective results, or to reduce the severity of symptoms if rosacea has already progressed. There are three major groups of skin diseases caused by allergy: eczema, allergic contact dermatitis and hives. Eczema occurs most commonly in children and involves red, thickened, swollen patches of skin on the cheeks, scalp, neck and trunk that itch and can be painful. Allergic contact dermatitis describes the onset of a rash, swelling, blistering or other effect after the skin touches an irritating substance such as clothing materials and dyes, latex, cosmetics, soaps, perfumes or certain plants like poison ivy. Sometimes the reaction is triggered by exposure to ultraviolet light (called photoallergy), for example putting on sunscreen and stepping outside. Hives, also called urticaria, are itchy rashes with bumps resembling insect bites. They can occur in small patches or all over the body, and last anywhere from a few minutes to several months. Known as nevi (singular “nevus”), moles and other birthmarks are benign pigmented spots or patches of skin that range in color from tan, brown and black (moles) to red, pink or purple (vascular nevi, such as strawberry hemangiomas or port wine stains). Though most birthmarks are harmless, they may develop into cancer. Depending on their depth, location and color, as well as the patient’s skin type, age and other factors, treatment for benign but unattractive birthmarks may take the form of laser or pulsed light therapy, microdermabrasion or surgical excision. A cyst is a fluid-filled lump that forms in the deeper layers of skin when a hair follicle becomes blocked. They can be uncomfortable and unsightly but are harmless (benign). Nevertheless, any suspicious growth on the skin should be examined by a dermatologist to determine whether it is cancerous. If infected, a cyst may require treatment with antibiotics. Patients with large or painful cysts may choose to undergo minor surgery. Cysts can occur anywhere on the body but commonly appear on the face and scalp, trunk and fingernails. They include acne whiteheads and comedones, milia, and dermoid, epidermal, trichilemmal and pilar cysts. |
