Learn more about psoriasis, its warning signs and how to treat it.

Psoriasis is a chronic inflammatory skin disease that can impact a person’s appearance, health and quality of life. You should turn to a dermatologist if you suspect that you might be dealing with psoriasis. While there is no cure for this disease, there are ways for a dermatologist to help you better manage your symptoms and provide you with relief.

What is psoriasis?

According to the National Psoriasis Foundation, more than 7.5 million adults in the US are living with psoriasis. This immune disorder causes widespread inflammation, particularly of the skin, which results in the development of raised, scaly red plaques on the skin. These plaques may also sting or burn and typically appear on the knees, elbows and scalp.

In some cases, some people with psoriasis may also develop joint stiffness, swelling and pain. This condition is known as psoriatic arthritis, and it’s essential that you turn to a doctor right away if you notice symptoms of arthritis and psoriasis.

What can cause psoriasis to flare up?

Psoriasis comes and goes, so it’s essential to recognize what triggers your flare-ups to avoid them as much as possible. Common triggers include,

  • Stress
  • Other infections, including skin infections
  • Cold, dry weather
  • Sunburn
  • Injuries to the skin such as a bug bite
  • Alcohol consumption
  • Steroid use
  • Certain drugs, such as high blood pressure medication
  • Smoking or being around smoke

When should I see a dermatologist?

If you notice red, cracked or dry patches of skin on your body, it’s a good idea to have your dermatologist look to determine whether or not you could have psoriasis. Suppose you have already been diagnosed with psoriasis. You may wish to turn to a dermatologist regularly if your current treatment plan isn’t working or noticing new or worsening flare-ups.

How is psoriasis treated?

The fast turnover of skin cells leads to the formation of these plaques. To prevent this rapid turnover, there are a variety of lifestyle, topical treatments and therapies that a dermatologist can provide you. Common treatment options for psoriasis include,

  • Topical steroids
  • Retinoids
  • Salicylic acid
  • Phototherapy
  • Biologics (for severe and treatment-resistant forms of psoriasis)

Suppose you live with psoriasis or think you might be dealing with psoriasis. In that case, it’s important that you turn to a dermatologist who can provide you with a proper diagnosis and customized treatment plan.

Wondering when a rash is a cause for concern?

We’re all going to deal with a rash at some point, and while the good news is that many of them can be treated from the comfort of your own home, sometimes you will need to turn to a dermatologist for medication. Here are the causes of a rash,

Fungal Infection

One of the most common fungal infections that result in a rash is ringworm. Fungal infections can also affect the nails and hair. Yeast infections caused by the candida fungus can also result in rashes of the mouth, groin, or vagina. Less common fungal infections may result in those with compromised immune systems (e.g., patients who have HIV).

Minor fungal infections may be treated with over-the-counter anti-fungal creams or ointments. A dermatologist should treat more severe or persistent fungal infections.

Viral Infection

The most common virus to produce a rash is the herpes simplex virus, both type 1 and type 2. Type 1 usually causes cold sores of the lips and nose, while type 2 leads to sores on the genitals. Those with an HSV flare-up may develop a tender rash on the palms. Chickenpox and shingles (caused by the herpes zoster virus) also result in itching, burning, and painful rashes.

Epstein-Barr virus, best known as mononucleosis or “mono,” can also lead to a mild rash that appears within a few days of being infected. If you develop a rash, a sore throat, swollen lymph nodes, and a fever, you should see a doctor.

Bacterial Infection

Staphylococcus (e.g., folliculitis; cellulitis; impetigo) and streptococcus (e.g., strep throat; scarlet fever) are two common bacterial infections that lead to a rash. Sometimes Lyme disease is characterized by a bull’s eye-like rash surrounding the tick bite.

Parasitic Infections

Parasites that cause a rash include lice and scabies, which can be passed from person to person. Lice most commonly affect the scalp, while scabies can cause an itchy, pimple-like rash that usually appears on the armpits, wrists, elbows, beltline, and buttocks.

Other Causes

Noninfectious rashes are also caused by drugs, eczema (e.g., atopic dermatitis), allergic dermatitis, autoimmune disorders (e.g., lupus), and food allergies.

It isn’t easy to tell what’s causing your rash, but if you are dealing with new, worsening, or severe symptoms or the rash is spreading, it’s always good to turn to your dermatologist for treatment.

Tags: Mole   Irregular Mole  
Irregular MoleEducating the public on skin cancer is incredibly important. After all, you’re the one that looks at your skin every day, so you should know how to spot early warning signs of skin cancer. While there are certain risk factors that can increase your risk for melanoma and non-melanoma skin cancers, it’s important for everyone to visit a dermatologist once a year for a comprehensive skin cancer screening. In the meantime, here’s what to look out for.

What is an irregular or atypical mole?

Medically referred to as dysplastic nevi, these irregular moles are benign but having them could put you at an increased risk for developing melanoma over your lifetime. These moles can develop anywhere on the body but are most often found on sun-exposed areas of the skin. Since these moles vary greatly in appearance it’s important to monitor your moles regularly so you can recognize when unusual changes are occurring and call your dermatologist.

What does an irregular mole look like?

The American Academy of Dermatology (AAD) offers a simple ABCDE guideline to follow to be able to spot unusual or suspicious changes in a mole. Here’s what the ABCDEs stand for:

Asymmetry: when the halves of the moles don’t match each other in shape or appearance this could be a sign of a cancerous mole
Border: a jagged, irregular, or scalloped border can be a sign of melanoma
Color: if a mole has multiple colors or changes color this is also a warning sign not to ignore
Diameter: melanoma is often larger than 6mm (the size of a pencil eraser), even though they can be smaller
Evolving: healthy moles stay relatively the same over the years so if your mole bleeds, crusts over, itches, or changes appearance you should schedule an appointment with your dermatologist

When should I see a dermatologist?

If you have any concerns about a mole don’t hesitate to call your dermatologist to have it checked out. The sooner melanoma and non-melanoma skin cancers are detected and removed the better. Of course, everyone can benefit from visiting a dermatologist at least once a year for a comprehensive skin cancer screening. You should also be performing self-exams once a month to keep track of your moles.

If you have an irregular mole or a mole that’s changing in appearance, it’s best to play it safe and schedule an evaluation with a dermatologist who can examine the mole to make sure it hasn’t turned cancerous.

Tags: Dry Skin  
Dry SkinFor most of the US, winter is here! Temperatures are dropping and snow is already falling. If you live in a wintry region of the country you may be finding that your skin is a little drier these days. If so, you aren’t alone. Dry skin is a common problem, particularly during the winter months. Here are some ways to improve dry skin on your own,

Pick the right moisturizer: Not all moisturizers are created equal but it’s important to quench your skin, particularly if it’s dry. Therefore, when you purchase a moisturizer look for one that contains lanolin or petroleum. These agents help to lock in moisture.

Other helpful ingredients to be on the lookout for include urea or lactic acid, which helps the skin hold water. However, those with eczema or sensitive skin may experience some stinging when applying products that contain lactic acid or urea.

Skip hot, steaming shower: While a hot shower after a long day might sound like heaven, it definitely won’t be for your skin. Hot water strips your skin of that much-needed moisture. The same goes for when you wash for face. Use warm water instead of hot and don’t linger in the shower.

Shave less frequently: Shaving can certainly be rough on skin, particularly if it is already dry. Therefore, it might be best to shave less frequently, if you can get away with it. On the days you do need to shave be sure to be generous with your shaving cream and to stick with warm, and not hot, water.

Use a humidifier: If you notice that your skin experiences more intense dryness during the winter months, then it might be time to invest in a humidifier. This household product can help add moisture back into the air, so your environment doesn’t suck all the healthy moisture from your skin.

Consider prescription medications: If you are suffering from extremely dry skin, then commercial moisturizers and other local drugstore skincare products just won’t cut it. You need to see your dermatologist for a topical prescription. We can prescribe corticosteroids and other medications that can help relieve the annoying itching and redness you experience with seriously dry skin. If over-the-counter products aren’t helping, talk to your dermatologist.

When to See a Dermatologist

It might seem strange to see a dermatologist for dry skin, but if your dry skin is severe, making you feel miserable and uncomfortable, or not responding to at-home treatments then it may be worth turning to a dermatologist for more effective treatment options.

Don’t let dry skin get you down this season when there are so many ways to get it under control. Remember that if dry skin and other issues are impacting your health, appearance, and confidence, a dermatologist can be the ideal doctor to help you feel better fast.

Tags: Carbuncle  
CarbuncleA boil is an infection of the hair follicle that develops under the skin. When multiple boils develop this is known as a carbuncle. In a carbuncle, this cluster of boils is interconnected under the skin and can lead to pain, inflammation, and redness. This infection most often develops on areas of the body that contain hair such as the neck, back, or armpits, but can also develop on the thighs and groin. Here’s what you should know about this condition, as well as how a dermatologist might treat this infection.

What causes a carbuncle?

Most of the time, bacteria known as staphylococcus aureus are to blame for carbuncles. This bacteria is already present on the skin, but can easily get into a hair follicle through a cut or opening. Since a carbuncle is the result of a bacterial infection, the infection can be spread to others by sharing items such as towels or through skin-to-skin contact. It’s important to cover the area and keep it clean so that it heals properly.

Who is at risk for carbuncles?

There are many risk factors that can cause someone to be prone to carbuncles. These risk factors include:
  • Chronic skin problems
  • Older age
  • Obesity
  • Poor hygiene
  • Liver disease
  • Diabetes
  • A weakened immune system
Of course, people don’t have to have these risk factors to develop this skin infection. Many health individuals deal with this issue too. For example, those in community settings such as a dorm room may be more at risk for spreading this infection.

How should I treat a carbuncle?

It is important that you do not pick at or squeeze the bump, as this can spread the infection even further or lead to scarring. Apply warm compresses to the area several times a day. Make sure to keep the area clean (wash with soap and water) and cover the area. Since heat can help to facilitate natural drainage, you may want to use a heating pad on the area for up 20 minutes at a time.

Should I see a dermatologist?

Since there are many infections and conditions that can lead to painful bumps and growths, it’s important that you see a dermatologist if you’ve never been diagnosed with a carbuncle before. If the carbuncle doesn’t drain after a few days or if it’s very painful or in a sensitive area such as the nose or eyes, it’s important that you see your dermatologist right away so they can drain it and properly treat it.

If you are dealing with any new or worsening bumps or growths on the skin that have you concerned, know that a dermatologist is going to be the best specialist to turn to for diagnosis and treatment. When in doubt, call your dermatologist to schedule an evaluation.
