Eczema (atopic dermatitis)

Eczema (atopic dermatitis) is a non-contagious chronic skin condition that produces an itchy rash. It is caused by a genetic condition that affects the skin's ability to protect itself from bacteria and allergens. The most susceptible are those with a family history of atopic dermatitis, asthma, or hay fever.

Infants will have a dry, scaly, itchy rash on the scalp, forehead, and cheeks. Older children will have the rash in the creases of elbows, knees, and buttocks.

Without treatment, a child may have trouble sleeping due to the intense itching. Constant scratching may cause skin infections.

Eczema cannot be cured, but it can be controlled through prescribed medications, skin care, stress management, and treatment of food allergies. People with eczema often have allergies to milk, nuts, and shellfish. Keeping the skin clean and moisturized helps prevent flares.

Rarity: Common

Top Symptoms: trouble sleeping, feeling itchy or tingling all over, dry skin, scalp itchiness, flexor surface rash

Symptoms that never occur with eczema (atopic dermatitis): fever

Urgency: Phone call or in-person visit

Mosquito bite

Mosquito bites are bites from flying insects that feed on the blood of animals, including humans. Mosquito bites are more common during the summer or in warmer climates, at dawn or dusk, and near bodies of water.

In most cases, mosquito bites will cause a local skin reaction that gets better on its own over days or weeks. Less commonly, children may develop recurrent itchy bumps called papular urticaria. In rare cases, some people may develop severe allergic reactions to mosquito bites. In addition, mosquitoes may carry viruses that cause encephalitis, Chikungunya Fever, and Zika virus.

The diagnosis is made by history and exam. Treatment options include washing the bite and using ice or cold packs or topical medications to relieve itching. More severe reactions may require oral allergy medications or epinephrine injection.

Rarity: Common

Top Symptoms: mosquito bite

Symptoms that always occur with mosquito bite: mosquito bite

Normal episode of itchy skin

Itchy skin is also called pruritis. There are a number of "normal" causes for itching, meaning the cause is not disease-related and does not result in seriously damaged skin.

The most common causes are:

  • Dry skin, due to bathing in soap or bubble bath that may be too harsh and is stripping the natural oils from the skin.
  • Mild allergies, which may be caused by dust; certain plants and flowers; nickel-containing jewelry; and any sort of soap, detergent, lotion, or perfume.
  • Pregnancy, due to stretching of skin or to a condition called prurigo. Prurigo causes small, itchy bumps which may be due to an autoimmune system dysfunction during pregnancy.

Menopause, due to hormonal changes that may leave the skin overly dry.

Diagnosis is made through physical examination and sometimes allergy tests.

Treatment involves bathing only with mild, hypoallergenic soap; regular moisturizing with unscented lotion; wearing soft, loose, non-synthetic clothing; avoiding any substances that seem to provoke the itching; and sometimes prescription medicated creams.

Rarity: Common

Top Symptoms: feeling itchy or tingling all over

Symptoms that always occur with normal episode of itchy skin: feeling itchy or tingling all over

Urgency: Self-treatment
