The beginning of summer kicks off the camping and hiking season, anxiously awaited by those who have endured a long cold winter. This year will likely prove to be one of the busier camping seasons as many Americans bypass more expensive vacations that involve pricey airline tickets or gas guzzling road trips. Emergency department staff will probably see a greater number of people with contact dermatitis caused by exposure to poison ivy, poison oak or poison sumac. Many people have never seen poison ivy , or perhaps wouldn't recognize it if they saw it. Poison ivy, poison oak and poison sumac belong to the plant genus Toxicodendron (previously referred to as Rhus ). Toxicodendron means "poisonous tree." These plants have an oil-based substance in the resin on their leaves and in their stems and branches called urushiol that causes a delayed skin reaction in about 50% of people that contact it. Urushiol may cause severe contact dermatitis in people that have previousl...

Allergic rhinitis is an inflammation of the nasal passages, usually associated with watery nasal discharge and itching of the nose and eyes. Allergic rhinitis affects about 20 percent of the American population and ranks as one of the most common illnesses in the U.S. The symptoms occur in the nose and eyes and usually occur after exposure to dust, danders, or certain seasonal pollens in people that are allergic to these substances. Two-thirds of all patients have symptoms of allergic rhinitis before the age of 30, but onset can occur at any age. Allergic rhinitis has no sexual predilection, although boys up to the age of 10 are twice as likely to have symptoms as girls. There is strong genetic predisposition to allergic rhinitis. One parent with a history of allergic rhinitis has about a 30 percent chance of producing offspring with the disorder; the risk increases to 50 percent if both parents have a history of allergies . Patients can be severely restricted in their daily activities, re...
