Description

Hives are a sudden eruption of red and white bumps on the skin. While hives are usually itchy, and therefore bothersome, they are generally not dangerous-except in cases of bee or insect stings, when hives indicate a true medical emergency. A case of hives may last for less than 30 minutes or as long as a week.

When the body comes into contact with a substance it considers dangerous, it floods the skin with histamine to combat the problematic substance. Hives result when there is excess buildup of histamine on a particular area of skin. Substances that cause this histamine release differ from person to person, though common irritants include animal dander, pollen, aspirin, penicillin, insect bites, and foods to which the person is allergic.

Signs and Symptoms

A batch of raised, red or white bumps on a localized area of skin

Bumps may appear and disappear suddenly

The affected area may be mildly or severely itchy

Certain people can develop recurrent hives from sunlight, cold, pressure, vibration or exercise. These are called the physical urticarias. If hives develop from scratching or firmly rubbing the skin it is called dermatographism. It is the most common of the physical urticarias and it affects about 5 percent of the population. It doesn’t always itch. This condition sometimes also occurs along with other forms of hives.

Conventional Medical Treatment

Hives often do not usually require medical treatment, but if the hives remain for an extended period of time, see your doctor. After taking your medical history, your physician may ask about your exposure within the last two weeks to any possible irritants. Unfortunately, hives can be caused by such a wide range of irritants that your physician may not be able to identify the exact cause. If the cause is identified, you will be urged to avoid the substance that caused the outbreak. In severe cases, your doctor may prescribe a medication, usually an antihistamine, to treat the condition.

If the hives are accompanied by shortness of breath, fever, nausea, or abdominal cramps, immediately seek medical help. You could be suffering from anaphylactic shock. Many antihistamines are available without prescription, such as diphenhydramine (Benadryl), taken in doses of 25 milligrams and chlorpheniramine (Chlor-Trimeton), taken in a dose of 4 milligrams. These can be taken up to three times a day, but because these medications can cause drowsiness, they are often taken at bedtime.

Aromatherapy

German chamomile oil can help bring relief from itching. Simply place a drop directly on the itchy skin and massage in.

Ayurvedic Medicine

Hives come from excessive heat in the body, say Ayurvedic practitioners. To cool the heat and soothe the maddening itch, they favor eating watermelon as well as drinking coriander milk or cilantro.

Basic Description

A first-degree burn is the most minor type of burn. It only affects the outer layer of skin-the burn is at the surface only. First-degree burns can be caused by the sun (sunburns), chemicals, or heated objects or fluids.

With a second-degree burn, the top layer of skin has been burned through and the second layer of skin has also been burned (though not burned through). Second-degree burns also can be caused by the sun (sunburns), fire, chemicals, or heated objects or fluids.

A third-degree burn is an extremely severe burn that damages the top and bottom layers of skin and the underlying layers of fat, nerves, muscles, and even bones. The area will be charred black or white and will be dry and Powdery. Third-degree burns are usually caused by fire, though they can also be caused by chemicals or electrical wires.

Signs and Symptoms

First-Degree

Pink or red areas that mayor may not be accompanied by swelling and blisters

Tenderness or pain at the site

Second-Degree

Mottled, intensely red areas

Blistering at the site, sometimes accompanied by oozing fluid

Intense pain

Swelling

Third-Degree

Charred black and/or white areas

Visible bone, fat, nerves and/or muscles

Victim may be in shock or unconscious

First and second-degree burns often accompany third-degree burns

Severe pain, or if the nerves have been burned, lack of feeling

Conventional Medical Treatment

Unless the first-degree burn is accompanied by more serious burns, or covers large areas of the hands, feet, face, groin, buttocks, or major joint, you can treat it at home. If the second-degree burn is limited to an area 3 inches in diameter or smaller, it can also be treated at home. If the skin is unbroken, run cool water over the area or soak it in a cool bath. Either way, keep the area submerged for 2 to 4 minutes. Then cover the burn with a sterile bandage or clean cloth. Minor burns usually heal without further attention. If an infection sets in, see your physician.

If the second-degree burn is larger than 3 inches in diameter, or has occurred on the feet, face, groin, buttocks, hands, or major joint, immediately go to your physician or hospital emergency room.

If any part of the body contains third-degree burns, immediately call an ambulance. If you are a bystander, check to see if the burn victim is breathing. If not, perform cardiopulumonary resuscitation (CPR). (If you are not trained in CPR, find someone who is.) If the person is breathing, cover the burned areas with a cool, moist, sterile bandage or a clean sheet (make sure it is a flatweave sheet rather than a fuzzy one). Do not apply any oils, ointments, or lotions, and do not move the victim.

Description

Unlike osteoarthritis, rheumatoid arthritis is an inflammatory, not degenerative, disease. It first appears as an inflammation in a joint’s synovium, the membrane that lines and lubricates the joint. Once inflamed, the membrane thickens and become sore and swollen-which in turn may limit the affected joint’s movement. In time, this inflammation spreads to other parts of the affected joint, causing even more stiffness and pain. Eventually, the inflammation can spread to organs, such as the heart, lungs, and eyes. Its ability to spread throughout the body makes rheumatoid arthritis a systemic disease-a disease that affects the entire body.

Inflammation is not a harmful state, per se. It’s actually your body’s normal response to infections and injuries, caused when your white cells battle an invading organism. Typically, the inflammation subsides after the infection is wiped out. However, with rheumatoid arthritis, the autoimmune system seems to fight the body instead of protecting it.

While the disease can strike at any time, it usually occurs between the ages 20 and 50. It affects approximately three times as many women as men.

Unlike illnesses that have a set progression of symptoms, rheumatoid arthritis is unpredictable. What symptoms appear, how often they appear, and what joints and organs are affected vary widely, depending on the individual. In some sufferers, rheumatoid arthritis will flare up occasionally, only to be followed by periods of normal health. Others experience recurring attacks without returning to a state of full wellness in between. Many experience a slow and steady increase in the severity of their symptoms over time.

Some people with rheumatoid arthritis develop small lumps under the skin near the elbow, ears, or nose, or on the back of the scalp, over the knee, or under the toes. Called rheumatoid nodules, these painless and non-problematic bumps range from the size of a pea to the size of a Ping-Pong ball.

While medical experts have not identified a single cause for rheumatoid arthritis, possibilities include heredity, viral or bacterial infection, and emotional stress.

Signs and Symptoms

Pain, swelling, redness, and warmth in the affected joint-most commonly affects the smaller joints of your hands and feet, but elbows, knees, and ankles can be affected

Usually affects joints symmetrically (both hands, for example)

Overall stiffness and achiness, especially after periods of stillness, such as sleeping or long plane rides

Symptoms are worse in the early morning and lessen as the day progresses. General malaise/weakness

Anemia

Pain usually occurs during rest and movement

Conventional Medical Treatment

A series of blood tests, along with a thorough physical exam and medical history, can confirm whether you have rheumatoid arthritis. X-rays may also be helpful. Strategies for treating rheumatoid arthritis differ, depending on whether it is active or in remission. During a flare-up, a combination of rest, heat, and medication is prescribed. Anti-inflammatory drugsaspirin, in particular are the first line of treatment and may ease symptoms. There are several other medications used to treat rheumatoid arthritis. Your doctor may prescribe gold salts, penicellamine, methotrexate, azathioprine, or anti-malarials, depending on how your symptoms progress. Corticosteroids can temporarily relieve pain and inflammation, but they are usually reserved for those with more serious disease.

Physical therapy plays a major role in the treatment of rheumatoid arthritis. It is most effective when swelling and inflammation of the joint are suppressed with medications. Physical therapy can reduce deformity and restore function.

In severe cases, surgical removal of affected joint lining can prevent damage to other joint structures and cartilage. Another surgical procedure fuses the painful, uncushioned bones together but is only performed on the wrist, feet, ankles, and thumbs because it restricts motion. Tendon transfer is another surgical option for repairing damaged tendons and ligaments it is performed most frequently on the hands. Another option is arthroplasty, or joint replacement, which is usually performed on knees, hips, and shoulders.
