Sand Fly Bites

Saturday, June 11th, 2016

The Sand Fly

Sand flies are about 1/8 of an inch long, and have hairy, brownish-gray wings, which they hold above their bodies in a “V” shape. In the U.S., they are found primarily in the southern states. They breed in places with a lot of moisture, such as decaying plants, moss, and mud. The larvae look like worms. They are most active between dusk and dawn. Sand flies eat nectar and sap, but females also feed on the blood of animals and humans. They live mainly in tropical and subtropical climates.

Sand Fly Bites

Sand flies are tiny and quiet, so you may not notice them before they bite. The bite can be painful and may cause red bumps and blisters. Sand flies transmit diseases to animals and humans, including a parasitic disease called leishmaniasis.

Fleabites bite

Friday, June 10th, 2016

What do fleabites look like?

Fleabites are pretty distinctive. They remain small, unlike mosquito bites. If a flea bites you, you may see one or more of the following:

  • bites that appear as small, red bumps
  • a red “halo” around the bite center
  • bites in groups of three or four, or in a straight line
  • bites that appear around the ankles or legs

Fleabites are also common around the waist, armpits, breasts, groin, or in the folds of the elbows and knees.

What are the symptoms of a fleabite?

Fleabites exhibit several common symptoms. They are very itchy, and the skin around each bite may become sore or painful. And you may experience hives or develop a rash near the site of a bite.

Additionally, excessive scratching can further damage the skin and a secondary bacterial infection can develop.

Avoid scratching if you can, and monitor your bite areas for signs of an infection, including white-topped blisters or a rash.

Can fleabites cause other problems?

For humans, the risk of contracting another disease from the flea is very, very small. That’s not true for your pets, however.

It’s important to take them to a vet if they have fleas.

How are fleabites treated?

Fleabites will go away without treatment. However, in order to stop being bitten you have to stop the fleas.

Your pet and your home will need to be treated with pesticides to kill the fleas. Professional pest control experts should administer these treatments.

In most cases, you will need to leave your home for several hours after the treatment has been deployed.

Do-it-yourself home treatments are available for fleas, but if they do not work, you may need to seek professional help.

To relieve the symptoms of fleabites, try over-the-counter anti-itch creams and antihistamine medications.

Avoid scratching the area. If you notice signs of an infection at the bite site, such as a white pocket or rash, make an appointment to see your doctor.

Eczema

Tuesday, January 20th, 2015

 

Eczema is a general term that describes several different conditions in which skin is inflamed, red, scaly, and itchy. Eczema is a common skin condition, and atopic dermatitis (also called atopic eczema) is one of the most common forms of eczema.Eczema can occur in adults or children. The condition is not contagious.

What Causes Atopic Eczema?

The cause of atopic eczema is not known, but the condition often affects people with a family history of allergies. Many individuals with eczema also have hay fever and/or asthma or have family members with those conditions.

Some factors can trigger a flare-up of eczema or make eczema worse, but they do not cause the condition. Eczema triggers include stress, skin irritants (including soaps, skin care products, or some fabrics), allergens, and climate/environment.

What Are the Symptoms of Atopic Eczema?

The appearance of eczema can vary from person to person. In adults, eczema occurs most frequently on the hands and elbows, and in “bending” areas such as the inside of the elbows and back of the knees. In young children, eczema is often seen on the elbows, knees, face, neck, and scalp. Signs and symptoms of atopic eczema include:

  • Itchiness
  • Skin redness
  • Dry, scaly, or crusted skin that might become thick and leathery from long-term scratching
  • Formation of small, fluid-filled blisters that might ooze when scratched
  • Infection of the areas where the skin has been broken

How Is Atopic Eczema Diagnosed?

Atopic eczema usually is diagnosed with an analysis of a person’s history of symptoms and with an exam of the skin. A doctor might test an area of scaly or crusted skin to rule out other skin diseases or infections.

How Is Atopic Eczema Treated?

Atopic eczema can be treated with medications, including over-the-counter creams and ointments containing the steroid hydrocortisone (for example, Cortizone-10, Cort-Aid, Dermarest Eczema, Neosporin Eczema). These products may help control the itching, swelling, and redness associated with eczema. Prescription-strength cortisone creams, as well as cortisone pills and shots, are also used for more severe cases of eczema

Can Atopic Eczema Be Prevented?

Currently, there is no effective strategy for preventing atopic eczema, but the symptoms of the condition can improve. To improve the signs of eczema:

  • Reduce stress
  • Avoid scratchy materials (for example, wool) and chemicals such as harsh soaps, detergents, and solvents
  • Moisturize frequently
  • Avoid sudden changes in temperature or humidity
  • Avoid situations that cause sweating and overheating

Types of Skin Rashes

Friday, January 9th, 2015

A skin rash is an area of skin that has become swollen or irritated. Skin rashes can include skin bumps or sores, scaly or red skin, and itchy or burning skin. Skin rashes can be caused by many medical conditions. Some skin rashes occur right away, while others take some time to develop. The location, appearance, and color of a skin rash are all important to help your doctor make the right diagnosis and start the right treatment.

Chickenpox: A Skin Rash Made Up of Blisters

The virus known as varicella zoster, more commonly called chickenpox, creates a skin rash of itchy blisters on the face that spreads down to cover the chest and back. It’s typically accompanied by fever and sore throat. Even though a vaccine is available, chickenpox is still common in children under age 12. Treatment is aimed at controlling symptoms, including fever with acetaminophen (Tylenol) or ibuprofen (Motrin, Advil), and the itch with creams and cold compresses.

Rubella: Red Spots All Over the Skin

Another viral skin rash that affects children and young adults is rubella, or German measles. Rubella causes a rash of red skin spots that spreads like chickenpox from the face down. The skin rash can be itchy. Other symptoms include sore throat, fever, swollen glands, headache, and runny nose. There is a vaccine for rubella, but about 10 percent of young adults are still susceptible. Rubella can be very dangerous for pregnant women because it can cause birth defects. Treatment is similar to that for chickenpox.

Hives: Sudden, Itchy Skin Bumps

Urticaria, also known as hives, is a skin rash that comes on suddenly and causes pale, itchy, or pink swellings on your skin, and burns or stings. This skin condition can occur anywhere on the skin. Up to 20 percent of people may experience hives at least once in their lifetime. Hives may last for a few days or a few weeks and may be caused by an allergic reaction to a food or medication. The most common treatment is to avoid the cause and treat the symptoms with an antihistamine medication.

Skin Rashes Caused by Medication

A drug-induced skin rash can be from an allergic reaction to a drug, a side effect of a drug, or from sensitivity to sunlight caused by a drug. A drug rash can occur right away after taking the drug, or up to several hours later. Types of drug rashes include hive or skin bump eruptions, purple or red skin discoloration, or scaly and thickened areas of skin. This skin condition can occur anywhere on the skin or even inside the mouth. Treatment is to stop taking the drug and manage the symptoms with antihistamines or steroids. In rare cases, drug-induced rashes can be serious or even fatal, so check with your doctor.

Prickly Heat: A Skin Rash That Stings

Prickly heat, or heat rash, causes red skin that stings and itches. Small skin bumps may form as well. Heat rash is caused when sweat gets blocked in your pores. This is a common rash in babies, but can occur at any age. This skin condition tends to form where skin rubs against skin, such as in skin folds of the neck, breasts, groin, and underarms. The best treatment is to cool off, dry off, and reduce friction.

Intertrigo: A Skin Rash in Body Folds

Intertrigo is a skin condition that occurs in skin folds, under the breasts, on the inner thighs, under armpits, or under belly folds. Chaffing causes a rash of red skin or brown skin that gets infected with yeast or bacteria and becomes raw. The skin rash may ooze and itch. This rash is more common in people who are overweight and in people with diabetes. Treatment involves keeping the areas dry, treating infections, and using steroid creams.

Rosacea: A Red Rash on the Face

Rosacea is a common skin condition that occurs on the face of adults. Symptoms ofrosacea include redness of the cheeks, nose, forehead, and chin. Small blood vessels may be seen on the surface of the red skin, along with skin bumps and pimples, though this is not related to acne breakouts. Rosacea only affects the face. The cause is unknown and there is no cure, although treatment with antibiotics can minimize symptoms.

Eczema: Red, Itchy Skin

Another word for eczema is dermatitis, or inflammation of the skin. Eczema causes your skin to be dry and itchy. Scratching makes your skin red and inflamed. Eczema is not contagious, and common causes include detergents, soaps, wool, and synthetic fibers. Eczema is common in babies and children, but can be seen at any age. The best treatment is avoiding substances that your skin is sensitive to.

Contact Dermatitis: A Skin Rash Caused by Irritation or Allergy

Contact dermatitis can be caused by any allergy-causing substance or irritating substance that touches your skin. Irritating substances are more common and include solvents, acid, and detergents. Allergic contact dermatitis is commonly seen with poison ivy, cosmetics, and medications that are applied to the skin. The skin rash of contact dermatitis can appear as red skin, skin bumps, blisters, scales, crusts, or sores. Itching is common. Treatment of contact dermatitis includes washing the skin and using anti-itch lotions and steroids.

Impetigo: A Skin Rash Caused by Bacteria

Impetigo is a rash caused by a skin infection, usually traced to one of two bacteria, group Astreptococcus or Staphylococcus aureus. This skin rash appears as brown, crusty sores or blisters around the nose or mouth area. The rash is very itchy and very contagious. Scratching the rash and then touching other areas of the body, or other people, will cause it to spread. Treatment of impetigo is with antibiotic creams or lotions, and for more severe cases, with oral antibiotics.
