Hot tub folliculitis is an itchy skin rash that develops due to an infection of hair follicles caused by the bacteria, Pseudomonas aeruginosa. This organism thrives in warm moist environments, hence, its occurrence in hot tubs (usually wood). It may also infect diving suits and natural or synthetic sponges. The bacteria can be controlled by proper chlorination and ph control of the water.The rash typically develops within hours to 2 days after exposure and often looks like acne with red bumps and pus pimples present on the trunk. Fortunately, it is self limited and generally clears spontaneously without scarring in 7-10 days. Treatment is directed toward symptomatic relief with topical cortisone creams and oral antihistamines. Occasionally, oral antibiotic treatment may be required.

This time of year we see an increased incidence of various insect bite and sting reactions. Fortunately, most are a mild nuisance but occasionally severe reactions occur. Localized reactions typically include redness, swelling, itching, and pain of the affected site(s). Simple home treatments include removal of the stinger (if applicable), application of a cold compress or ice, application of 1% hydrocortisone cream, ingestion of an OTC antihistamine, e.g., diphendydramine (Benadryl), Cetirizine (Zyrtec), etc. Ibuprofen (e.g. Advil, Motrin) or acetaminophen (e.g. Tylenol) can help relieve pain. Serious symptoms requiring immediate medical attention at the nearest hospital's emergency department include:

• Wheezing
• Shortness of breath
• Chest tightness or pain
• Sensation of the throat closing or difficulty speaking or swallowing
• Faintness or weakness
• Infection (If the wound appears infected and you are not able to reach your doctor, seek care at a hospital.)

Summer is a great time for hiking (provided you incorporate appropriate sun protection measures!) In addition to getting exercise and being in the midst of beautiful scenery, exposure to poison oak is common. Most adults will develop an allergic rash upon exposure to urushiol oil, a resin present in poison oak, ivy, and sumac. The intensity of the rash varies and tends to be more severe with subsequent exposures. The eruption usually develops within days of exposure and commonly spreads beyond the sites of contact due to the body's immune response to the resin. The rash usually appears as red, swollen, linear streaks that have a "painted on" appearance. Fluid filled blisters are common but the contents are not contagious.Avoiding exposure to the plant is achieved by wearing long pants, long sleeved shirts, and following the advise, "leaves of three, let them be!" If you think you've been exposed, removing the resin by washing with soap and water might prevent the rash from developing. Laundering clothing separately in warm water is also a good idea.Finally, if you develop the rash, OTC hydrocortisone cream and oral antihistamines such as diphenhydramine (Benedryl) or cetirizine (Zyrtec) can help mild reactions. For moderate to severe reactions, prescription topical steroids or oral steroids (eg prednisone) are often required.

Peak sun hours, when UV light is strongest, are between 10 a.m. and 4 p.m. When possible, plan outdoor activities for early morning or late afternoon when the sun's rays are less intense.Wear protective clothing including a broad brimmed hat and UV blocking sunglasses. Apply a broad spectrum, UVA/UVB sunscreen with an SPF 30 or higher a half hour before sun exposure. Adults should use approximately 2 tablespoons of product (a shot glass) to cover their body. Re-application every 2 hours and after water exposure or heavy sweating is advisable. Newborns should be kept out of the sun, and apply sunscreen to babies over 6 months of age.If you do, however, end up getting too much sun, as long as you are not allergic, acetaminophen is a great way to find a bit of relief from a mild sunburn. Additionally, avoid heat and apply a cool water compress to affected areas. You can also treat a mild sunburn by gently applying a light unscented over the counter moisturizer. For more severe sunburns, seek medical attention asap.

While people with fair complexions are most susceptible, anyone can develop melanoma. One in five Americans will be diagnosed with skin cancer during their lifetime and melanoma is the most common cancer for women between the ages of 15 and 29. When discovered early and treated, the cure rate is nearly 100%. Allowed to grow, melanoma can spread to other parts of the body and can be deadly.Here's the good news: Mortality from melanoma can be greatly reduced if people are aware of the warning signs of melanoma and learn how to examine their skin for signs of skin cancer.The physicians of Dermatology Associates Medical Group have expertise and years of experience in detecting and treating skin cancer.

Rosacea is a common, chronic, facial skin condition that affects approximately 1 in 20 people. Women are affected more frequently than men, but men tend to have more severe symptoms. Typical signs and symptoms include:

• Spider-like blood vessels of the face
• Generalized or central location redness of the face
• Acne-like eruptions
• A stinging sensation of the face
• In some extreme cases a red and bulbous nose

A common misconception is that acne is a condition unique to teens and people in their 20s. Adult onset acne, however, can develop in the 30s, 40s, and even 50s. Seen mostly in adult women, it's sometimes triggered by hormonal changes (menses, pregnancy, menopause), medications, (e.g. anticonvulsants, corticosteroids, certain birth control pills), oil containing skin and hair care products, underlying medical conditions, and stress. Often, a clear cause isn't evident. Fortunately, many treatments options are available.At Dermatology Associates Medical Group we have expertise in treating all forms of acne.

Bumps that come from shaving, aka Pseudofolliculitis barbae (PFB), occur when the hair grows into the skin causing unsightly, and sometimes painful, pimples. It primarily affects curly-haired men, but is also seen in women. Pseudofolliculitis pubis is a similar condition occurring after pubic hair is shaved.This annoying condition can be managed by the following: washing with a gentle soap and warm water before shaving; reducing the frequency of shaving; using a triple blade safety razor with a shaving gel or using an electric razor; and applying an alum mineral block to the skin after shaving. Hydrocortisone 1% cream can also be applied periodically after shaving to reduce irritation.If these measures are inadequate, prescription medications are available from your dermatologist. Finally, laser hair removal can be a very effective treatment for this condition.
