Pruritic urticarial papules and plaques of pregnancy (PUPPP) is the most common skin condition of pregnancy. Typically, women affected by PUPPP develop red, itchy bumps on the belly near stretch marks (striae) during their third trimester. PUPPP usually gets better within a few weeks after delivery, does not affect the health of your baby, and has no long-term consequences for you.
Most bites and stings from insects (arthropods) are painful or itchy but harmless. Usually, the person who has suffered the bite or sting develops some pain, redness, or itchiness at the site that goes away within hours to days. People with more sensitive skin will often have a more dramatic reaction (eg, more redness or a bigger bump), but the bite is still usually harmless. Where the bite occurs on the body can help determine what kind of insect was involved; flying insects tend to bite the head and torso, while jumping insects, such as fleas, tend to bite the feet and legs. A very small portion of the population is allergic to the bite or sting of some common insects, such as wasps and bees, and the allergic person will experience a severe reaction, including hives (raised welts) all over their body, itchiness, trouble breathing and swallowing, and unconsciousness. An allergic reaction to a bite or sting may be fatal. Anyone who suspects this sort of allergy should discuss it with their doctor; they may need to carry a special sort of medicine that can be injected in case of emergency to reverse the allergic reaction.
Bites or stings from insects (arthropods) are very common. Most reactions are mild and result due to an allergic reaction to either the insect or the toxins injected with the bite or sting. Some people have severe reactions to the stings of:Bees Wasps Hornets Yellow jackets These stings may require emergency help. The bites of most insects – such as ants, mosquitoes, flies, spiders, ticks, bugs, and mites – do not cause such a severe reaction.Sometimes, it may be hard to tell which type of insect has caused the skin lesions, as many insect reactions are similar. Flying insects tend to bite any exposed skin areas, while bugs such as fleas tend to bite the lower legs and around the waist and often have several bites grouped together. Some individuals are far more sensitive to insects and have more severe reactions, so the fact that no one else in the family has lesions does not rule out an insect bite.First Aid GuideFor stings:Bees may leave a stinger behind – Try to gently scrape off the stinger with a blunt object, such as a credit card. Wash the wound with soap and water. Apply an ice pack or cold water for a few minutes. Take acetaminophen for pain and an antihistamine (diphenhydramine or chlorpheniramine) for itching, as needed.For insect bites:Wash with soap and water. Apply cool compresses. Use antihistamines to relieve itching and take acetaminophen for pain. 1% hydrocortisone cream may help reduce the itching. For ticks (still attached), see the first aid section on Tick Bites.
Bites or stings from insects (arthropods) are very common. Most reactions are mild, and symptoms are caused by an allergic reaction to either the insect or the irritating substances (toxins) the insect makes and injects along with the bite or sting.Some people have severe reactions to the stings of:Bees Wasps Hornets Yellow jacketsGet medical help immediately for severe stings. The bites of most insects (such as ants, mosquitoes, flies, spiders, ticks, bugs, and mites) do not cause such a severe reaction.Sometimes, it may be hard to tell which type of insect has caused the skin reactions, as many insect reactions look the same. Flying insects tend to bite or sting uncovered (exposed) skin areas, while bugs such as fleas tend to bite the lower legs and around the waist, often with several bites grouped together.Some people are far more sensitive to insects and have more severe reactions, so the fact that no one else in your family seems to be affected does not mean that your child has not suffered an insect bite.
Perioral dermatitis is an acne-like problem commonly seen around the mouth in children.Children are otherwise well, but they develop small pink bumps around the mouth and sometimes around the nose and eyes. The rash may be mildly itchy (pruritic) and it may come and go (wax and wane) over time. Using a topical steroid may trigger perioral dermatitis. Fluorinated dental care products and skin products containing petrolatum, paraffin, or isopropyl myristate may also trigger the condition.
Stretch marks (striae) are stripe-like skin marks that develop as a result of rapid weight gain or loss, when the skin is stretched, and as a result of some diseases.
Bedbugs are small wingless insects (Cimex lectularius) that come out at night to feed. They live in dry, dark crevices such as the seams of mattresses, furniture, floorboards, wallpaper, and suitcases. Their only food source is blood, and they can live for up to a year without a meal. Their bite is painless, so you will likely not be awoken. They usually feed in the very early morning hours, which explains why they are mostly found in and around your bed. It can take up to 30 minutes for them to complete their meal. In the absence of the bedbug's preferred human host, it will feed on any warm-blooded mammal.
Chickenpox (varicella) is an infectious disease caused by the varicella-zoster virus that goes away on its own. Infection spreads among humans through fluids from the airways, such as from coughing and sneezing, with non-infected household members at high risk of becoming infected as well. The development (incubation) period is 14–16 days, and the first sign of disease is a rash. People are considered contagious for 2–5 days before the onset of skin lesions and for 6 days after the last series of rashes have appeared.The most common complication is infection of lesions with bacteria. Rare complications include lung infection (pneumonia) or brain infection (encephalitis). Children who have weak immune systems, eczema, or recent sunburns have more severe symptoms. Because the virus remains resting (latent) in the parts of nerves that are near the spinal cord (nerve roots) for life, about 1 in 10 adults will get shingles (zoster) when the virus reappears, usually under conditions of stress to the body.After having chickenpox, a person is usually immune for life, although reinfection is possible.
Dermatologists have many strategies and tools available to treat skin conditions. One treatment that is very common in dermatology clinics is prescribing topical steroids. Steroids are used to treat common skin conditions such as eczema, psoriasis, and contact dermatitis. However, many patients wonder why they are being prescribed a topical steroid and how these medications can improve their skin conditions.
Poison ivy usually has to run its course. In the meantime, symptomatic treatments such as calamine lotion, Aveeno® oatmeal baths, Domeboro® compresses, or topical corticosteroids may help relieve itching.
In this two-part series we continue to cover various prescribed methods for evening out skin tones. Part 1 looked at hydroquinone and mequinol. Part 2 covers azelaic acid, corticosteroids, and more. Azelaic Acid: Treat both acne and pigmentation disorders This medication works wonders for acne, destroying acne-causing bacteria before they have the chance to cause outbreaks. An additional benefit is that it is a very effective treatment for post-inflammatory hyperpigmentation, much of which is caused by acne outbreaks. So it works on two levels – improves acne and some of the pigmentation disorders that appear with it.
In this two-part series we continue to cover various prescribed methods for evening out skin tones. Part 1 looked at hydroquinone and mequinol. Part 2 covers azelaic acid, corticosteroids, and more. In my practice, one of the most common concerns among people of color is uneven skin tone due to hyperpigmentation, or irregular darkening of the skin. Over the past few months, I’ve written a number of posts about hyperpigmentation concerns – including irregular patches, spots and scars – and which conditions warrant a consultation with a dermatologist.
Pseudofolliculitis is the medical term for those pesky lesions more commonly known as “razor bumps,” “shaving bumps,” and “ingrown hairs.” It is a common, chronic condition that can be quite bothersome for those affected.
Fleas are bloodsucking parasitic insects that live on pets, livestock, and humans. Human fleas (Pulex irritans) are relatively uncommon, and the species most likely to bite humans is the cat flea (Ctenocephalides felis) or the rat flea (Xenopsylla cheopis).
