Prickly Heat Rash

Prickly heat rash or miliaria rubra is the most common type of heat rash. In this form of heat rash, the sweat duct becomes red and inflamed, and may cause a ‘prickling’ or stinging sensation. This type of heat rash may also cause mild itching. There are three types of miliaria, which are classified according to where the sweat ducts are blocked.

§  Miliaria rubra. Occurring deeper in the outer layer of skin, miliaria rubra causes red bumps that are intensely itchy or prickly, giving rise to its common name, prickly heat rash. There is often little or no sweating in the affected areas. Adults can develop miliaria rubra shortly after they’re exposed to hot weather, but the rash more often appears after several months of exposure. Infants usually develop this type of heat rash between the first and third weeks of life.

§  Miliaria crystallina. The mildest form of heat rash, this affects the sweat ducts in the stratum corneum, the topmost layer of skin. Miliaria crystallina is marked by tiny, clear, superficial blisters and bumps (papules) that break easily but aren’t itchy or painful. It usually clears on its own in a few days but can come back if hot, humid weather persists. And though it’s most common in newborns, adults can develop it, too, especially if they’ve recently moved from a temperate climate to the tropics.

§  Miliaria profunda. A less common form of heat rash, miliaria profunda occurs mainly in adults who have had repeat bouts of miliaria rubra. It affects the dermis, a deeper layer of skin, and appears soon after exercise or any activity that causes sweating. The lesions are firm and flesh-colored, much like goose bumps. Though it’s not uncomfortable, miliaria profunda can cause a widespread lack of perspiration, leading to symptoms of heat exhaustion, such as dizziness, nausea and a rapid pulse.

The best treatment for any form of heat rash is to reduce sweating by staying in air-conditioned buildings or, when that’s not possible, using fans to circulate the air, wearing lightweight clothing made of fabrics that breathe and limiting physical activity. Once skin is cool, heat rash tends to clear quickly.

Occasionally, heat rash becomes infected with bacteria, causing inflamed and itchy pustules. This is especially common in children in diapers but shouldn’t be confused with diaper rash, which results from irritation to tender skin, not from blocked pores.  In hot weather, people with miliaria profunda are at risk of heat exhaustion, which can cause low blood pressure, nausea, headache and a rapid pulse. Untreated heat exhaustion can lead to heatstroke, a life-threatening condition.

Rash

A rash indicates an abnormal change in skin color or texture. Rashes are usually caused by skin irritation, which can have many causes. A rash is any bumps or spots on the skin. The rash can be red, skin-colored, or slightly lighter or darker than skin color. Prickly heat causes rash or blotches during hot weather or in a hot environment just like a heat rash.

Hives are red welts that appear to move around on the body. They differ in size and shape and are usually very itchy. The most common cause of hives is a viral infection. There is no treatment for the virus, and the hives may last for a few weeks. You can use antihistamine medication for the itching. Sometimes bacterial infections cause hives. These are treated with antibiotics. Sometimes hives can be a sign of an allergy. This is best determined by your health care provider.

Milia/miliaria are tiny white, clear or red bumps on the skin.  These usually occur on the face and chest. Usually the white or clear ones are seen in newborns. The red ones are also called heat rash or prickly heat.

Baby acne is caused by exposure to the mother’s adult hormones. Little white dots often seen on a newborn’s nose represent an abnormal amount of normal skin oil that is a result of these hormones. Acne usually occurs between 2 and 4 weeks of age, but may appear up to 4 months after birth and can last for 12 – 18 months.

Eczema is a condition of the skin in which areas are dry, red (or darker than normal skin color), and itchy. When it goes on for a long time the areas become thickened. It is often associated with asthma and allergies, although it can often occur without either of these. Eczema often runs in families.

Cradle cap causes greasy, scaling, crusty patches on the scalp that appear in a baby’s first 3 months. It usually goes away by itself, but some cases may require treatment with medication.

Erythema toxicum can cause flat red splotches. These splotches are usually with a white, pimple-like bump in the middle and appear in up to half of all babies. These blotches rarely appear after 5 days of age, are usually gone in 7 – 14 days, and are nothing to worry about.

Most baby rashes cause no harm and go away in time on their own.

Folliculitis

Anyone can develop Folliculitis wherever hair follicles are present on the body. The lesions in Folliculitis most often affect the chest, back, and legs. Other common locations include the face, neck, thighs and buttocks. Although not impossible, it is rare to have it widespread all over the body. It does not affect the eyes, mouth, palms, or soles, where there are no hair follicles. Folliculitis is estimated to affect more 10%-20% of people at some point in their lives.

Folliculitis is a common skin condition that appears as numerous small red or pink little bumps at hair follicles. It can cause a “chicken skin” appearance on the skin. Folliculitis can affect any part of the skin, including the chest, back, arms, legs, buttocks, and cheeks.

Folliculitis usually looks like red pimples with a hair in the center of each one. The pimples may have pus in them, and they often itch or burn.  Folliculitis often appears as very small, slightly smooth bumps are scattered in a body area like the back. Some of the bumps may be slightly red or have an accompanying light-red halo indicating inflammation. Sometimes, scratching off the top reveals a small trapped or coiled hair within.

Razor-burn Folliculitis is very common on women’s legs and is caused by shaving. It may also be seen on the faces and necks of men.  Some people are simply more prone to developing Folliculitis because of their overall health, possible altered immune status, exposure history, and other predisposing skin conditions like eczema or severely dry skin. You are more likely to get Folliculitis if you use a hot tub, whirlpool, or swimming pool that is not properly treated with chlorine. Wearing tight clothes, using antibiotics or steroid cream for long periods and if you use or work with substances that can irritate or block the follicles you are more prone to develop this condition. Also if you have an infected cut, scrape, or surgical incision the bacteria or fungi can spread to nearby hair follicles. Having a disease such as diabetes or HIV that lowers your ability to fight infection could also put you at risk.

Overall, Folliculitis is often not a pretty sight but is medically harmless. Many cases of Folliculitis may resolve on its own without any treatment. Folliculitis frequently affects otherwise healthy people. Treatment may typically include one or a combination of antibacterial washes, antibiotic creams or lotions, and antibiotic pills.

Heat Rash Babies

Most bumps and blotches on a newborn baby are harmless and clear up by themselves. A rash is any skin bumps or blotches. The rash can be red, skin-colored, or slightly lighter or darker than skin color. By far the most common skin problem in infants is diaper rash.

Another common skin problem that occurs with babies is heat rash. With heat rash babies pores of the sweat glands become blocked. This generally happens when the weather is hot or humid. As the infant sweats little red bumps and possibly tiny blisters form because the blocked glands cannot clear the sweat.  When the weather is hot or humid, the infant sweats, but because of the blockage of the sweat glands, this sweat is held within the skin and forms little red bumps, or occasionally small blisters in young infants.

Some helpful suggestions to avoid heat rash are during the hot season dress your baby in light-weight, soft, cotton clothing. Cotton is very absorbent and keeps moisture away from the baby’s skin. If air conditioning is not available a fan may help evaporate moisture and cool the infant. Place the fan far enough away that there is only a gentle breeze drifting over the infant. Avoid the use of powders, creams, and ointments. Baby powders don’t improve or prevent heat rash. Creams and ointments tend to keep the skin warmer and block the pores. Most often, heat rash goes away on its own. Severe forms of heat rash may need medical care, but the best way to relieve symptoms is to cool your skin and prevent sweating.

Heat rash is also known as prickly heat and miliaria and it does not just affect babies. Though it’s most common in infants, heat rash affects up to a third of adults living in tropical climates and can bother anyone during hot, humid weather. Heat rash develops when your sweat ducts become blocked and perspiration is trapped under your skin. Symptoms range from superficial blisters to deep, red lumps. Some forms of heat rash can be intensely itchy or prickly.

Heat rash usually heals on its own and doesn’t require medical care. See your doctor if you or your child has symptoms that last longer than three or four days, the rash seems to be getting worse or there are signs of infection such as increased pain, swelling, redness or warmth around the affected area or pus draining from the sores.  Swollen lymph nodes in the armpit, neck or groin and fever or chills are all warning signs of a more serious condition.

Eczema Pictures

Eczema is a disease in a form of dermatitis or inflammation of the epidermis. The term eczema is broadly applied to a range of persistent skin conditions. Eczema pictures show this to include dryness and recurring skin rashes which are characterized by one or more of these symptoms: redness, skin edema which is swelling, itching and dryness, crusting, flaking, blistering, cracking, oozing, or bleeding. Areas of temporary skin discoloration may appear and are sometimes due to healed lesions, although scarring is rare.

Doctors do not know the exact cause of eczema, but an abnormal function of the immune system is believed to be a factor. Some forms of eczema can be triggered by substances that come in contact with the skin, such as soaps, cosmetics, clothing, detergents, jewelry, or sweat. Environmental stimulants like substances that cause allergic reactions may also cause outbreaks of eczema. Changes in temperature or humidity, or even psychological stress, for some people lead to outbreaks of eczema.

Eczema can be intensified by dryness of the skin. Moisturizing is one of the most important self-care treatments for sufferers of eczema. Keeping the affected area moistened can be beneficial to skin healing and relief of symptoms. There is no known cure for eczema, so the treatments aim to control the symptoms like reduce inflammation and relieve itching.  Corticosteroid creams are sometimes prescribed to decrease the inflammatory skin reaction in eczema sufferes.

While any area of the body may be affected by eczema, in children and adults, eczema typically occurs on the face, neck, and the insides of the elbows, knees, and ankles. In infants, eczema is commonly seen on the forehead, cheeks, forearms, legs, scalp, and neck.

Eczema can sometimes occur as a brief reaction that only leads to symptoms for a few hours or days. In other more severe cases, the symptoms persist over a longer time and are referred to as chronic dermatitis.

Soaps and harsh detergents should not be used on affected skin because they can strip natural skin oils and lead to excessive dryness. Instead, the use of moisturizing body wash, or an emollient like creams or lotions, will maintain natural skin oils and may reduce some of the need to moisturize the skin. Another option is to try bathing using colloidal oatmeal bath treatments. In addition to avoiding soap, other products that may dry the skin such as powders or perfume should also be avoided.
