A 10-Year-Old Presents With ‘Itchy Bumps' on His Extremities
A 10-year-old boy presented to the dermatology clinic for evaluation of 'itchy bumps' on the arms and legs over several months. The child is medically well with a history of mild asthma. The exam shows erythematous papules and vesicles on the upper and lower extremities, along with scattered crusted lesions and hypopigmented ring lesions (Figures 1 and 2). Figure 1. Figure 2. The correct diagnosis is bug bite hypersensitivity. Discussion The clinical evaluation showed several scattered erythematous papules that appeared in a linear morphology, along with scattered vesicles. The vesicles had clear fluid, without purulence (Figure 2). These clinical findings suggest a clinical diagnosis of hypersensitivity to bug bites, also known as papular urticaria. The pattern on the arms is consistent with the 'breakfast, lunch, and dinner' sign of bug bite reactions (Figure 1). Both flea bites and mosquito bites can elicit a skin reaction that typically consists of edematous papules with associated pruritus. There are two phases to the reaction: immediate and delayed. The immediate reaction results in an edematous, erythematous papule within 20-30 minutes of the mosquito bite. The delayed reaction results in pruritic papules for up to 1-3 days. These itchy papules can cause sequela such as possible scarring, hyperpigmentation, and infection from secondary excoriations. Typically, they do not cause systemic reactions, but this can occur in rare occurrences. Hypersensitivity reactions may result in vesicles that can range from 1-2 mm up to several centimeters in size. Other arthropods, such as bedbugs, may cause similar lesions. It is thought that the mechanism of action is an immunologic response elicited from an anticoagulant in mosquito saliva. The exposure activates mast cells via immunoglobulin (Ig)E antibodies; however, some findings also demonstrate recruitment of non-IgE mediated immune responses. In a small subset of individuals, an amplified immune response can occur, causing a large local reaction, defined as an erythematous wheal larger than 5 mm. These individuals are thought to have mosquito allergy. One study found that children with atopy were more likely to have amplified reactions to mosquito bites: 35% of those with mosquito allergy had atopy compared with only 12% of control subjects ( P <.001). Additionally, 32% of children with intense bite reactions were found to have other atopic diseases such as asthma, allergic rhinitis, or eczema. Skeeter syndrome is a large, local inflammatory response to mosquito bites that is usually accompanied by fever and lymphadenopathy Additionally, studies have shown that there is evidence of varying human susceptibility to mosquito bites and associated itch. Monozygotic and dizygotic twin studies have demonstrated that there is a stronger genetic association to mosquito bite susceptibility in identical twins. This suggests that the relationship between genetics, skin microbiome, and body odor can alter mosquito attractivity to individuals. An important consideration when approaching management of hypersensitivity to bug bites is avoidance. Mosquitoes are found near areas with standing water because of their life cycle. Therefore, avoiding these areas and increasing physical barriers with protective clothing and mosquito nets is useful in decreasing mosquito bites. Insect repellants, including DEET, can be highly effective but in rare cases can cause adverse reactions. The mainstay treatment for mosquito bites is second-generation antihistamines and topical steroids. It may also be reasonable to treat with topical mupirocin if signs of impetigo are present. Management of fleas often includes treating pets and applying household treatments, which can include vacuuming and washing of bedding and carpets, and pest control services. The differential diagnoses for hypersensitivity to bug bites can share similarities in presentation, but ultimately there are key differences in the morphology and clinical course. Allergic contact dermatitis is a type of skin inflammation mediated by an allergic response after exposure to a substance. It typically presents as an eczematous dermatitis with vesicles, oozing, crusting, and sometimes bullae formation in areas of the skin with direct exposure to the allergen. Given this presentation, the location and morphology are often signs of this reaction, such as a rash on the wrist after wearing nickel-containing items or linear streaks from brushing against poison ivy, poison oak, or poison sumac. Cellulitis is caused by a bacterial infection of the dermis and subcutaneous tissue introduced via a break in the superficial skin. It presents as an area of well-defined erythema associated with pain, swelling, and warmth. Folliculitis is caused by inflammation that affects hair follicles. Because this process targets the hair follicle unit, folliculitis typically presents as small, itchy, erythematous papules in areas with significant hair growth that can progress into erythematous pustules. Varicella is characterized by an acute fever and widespread pruritic erythematous papules that progress into vesicles on an erythematous base ('dewdrop on a rose petal') before finally crusting.

Cuts, scrapes and bug bites are common for kids. A Maryland dermatologist shares tips for treating them.
During the summer, it's common for kids to come home with small cuts and scrapes or pesky bug bites. Maryland dermatologist Dr. Kate Viola recommends that families keep some products handy to treat small injuries. Preventing bug bites Dr. Viola, a board-certified dermatologist with Dermatology Partners in Sparks, Maryland, said prevention is key when it comes to mosquito bites and bee stings. "The American Academy of Pediatrics highly recommends the use of DEET in [children] two months old and above," said Dr. Viola. DEET can be found in bug repellent products like OFF. Dr. Viola said it's safe to use on kids' sensitive skin. Treating bug bites According to Dr. Viola, it's important to immediately identify the bug bite before treating it. There are two simple ways to get relief. Dr. Viola recommends a cold compress to help relieve the itching and pain. Another tip is to use skin care products that are cold. She recommends putting moisturizers and anti-itch lotions like CeraVe in the refrigerator. "It will make a huge difference over time, and it will cool down the area, so that's very important," Dr. Viola said. When to see a doctor If your child is having trouble breathing or swallowing after a bug bite or sting, and it begins to look like an anaphylactic episode, Dr. Viola urges parents to call 911 immediately. "If the bug bite just does not go away, and it's very painful for the child even after giving – you can give a children's acetaminophen, Motrin, ibuprofen – If that does not help, seek the advice of your pediatrician or a dermatologist for sure," Dr. Viola said. Treating cuts and scrapes Dr. Viola suggests choosing Vaseline over Neosporin when treating common cuts and scrapes. "The problem with Neosporin and products like Bacitracin is that for many people – including adults and children – there are ingredients that patients can also be allergic to, children can be allergic to," Dr. Viola said. To treat cuts and scrapes, she recommends products like Vaseline because it acts as a barrier to protect the skin, and it's inexpensive. She also recommends Aquaphor and CeraVe Healing Ointment. "All of these are just great for cuts and scrapes, so just put that on," Dr. Viola said. "That's so much better for the skin, and you won't get an allergic reaction."

We Gave This Bite-Relief Tool A Try — Here's How It Worked
Stay prepared this summer with this suction tool. Let's be honest—no one likes bug bites! But they're almost impossible to avoid, especially if you're one of those people mosquitoes seem to love a little too much. If that sounds like you, or if you always end up being the one who gets stung by a bee, this little tool might just save the day. The Bug Bite Thing is a small, portable device that claims to remove venom, saliva, and other irritants left under the skin by insects. This handy gadget has been all over the internet lately, so we decided to test it out and see if it really works. This text is a translation from Noovo Moi Valérie Sardin How does it work? The process is pretty simple—The Bug Bite Thing uses suction to draw out venom and saliva from just under the skin at the site of a bug bite or sting. According to the instructions on the packaging, the best way to use it is to place the tip of the tool directly over the bite or sting. Then, gently pull up on the handles until you start to feel some suction. Hold it there for 10 to 20 seconds, then slowly release the handles. Valérie Sardin Valérie Sardin You should feel a noticeable suction, but stop before it becomes uncomfortable or painful. Then, press down on the handles to release the suction and repeat the process two to three times. When used properly, you should notice a reduction in pain and irritation within a few minutes. Valérie Sardin What kinds of bites does it work on? Since this tool uses suction to pull out saliva and venom, it works on all kinds of biting insects: mosquitoes, bees, wasps, ants—you name it. You won't actually see the venom being sucked out because the particles are just too tiny. They also say it can be used to remove bee stingers or even splinters under the skin. The suggestion is to first use the regular tip to bring the splinter closer to the skin's surface, then use the opposite side—which acts like a scraper—to pull it out. Oh, and they strongly recommend washing the tool after every use to avoid contaminating any future bites. Amazon Can you use it on kids? I'll be honest—the suction is pretty strong, even though it's said to be painless. I actually worried it might leave a mark for a few days, kind of like a hickey! But the good news is, you can control the suction by covering more or less of the area you're treating. With kids, you should use less suction and keep it on for a shorter time. That said, the tool can be used at any age, even on babies. Plus, since it helps reduce the urge to scratch, it lowers the risk of infection, which is great for little ones who often have dirty nails. Amazon Does it really work? After a few uses, my kids and I definitely noticed a reduction in the bites we treated. That said, you really need to repeat the process two to three times to get results. The only downside is that sometimes the suction can leave a mark on the skin for a few hours or even a day. Maybe it's just about adjusting the suction strength properly? Only using it more over time will tell. Also, some people seem more prone to marks than others. But yes, the tool really does work on bites. Here are some tips from the manufacturer: Use the device as soon as you notice a bite—the sooner, the better it works. Keep several Bug Bite Things handy in different spots (garage, car, purse, etc.). Make the most of it by using the handles as a scraper to remove bee stingers or splinters. 14 Alcohol-Free Beers, Spirits, And Pre-Mixed Mocktails That Taste Just As Good As The Real Deal If You're On The Hunt For Bug Deterrents, Here Are A Few Of The Best You Can Get In Canada Right Now The Absolute Best Spray-On Deodorants You Can Get In Canada Right Now Disclaimer: The prices displayed are accurate at the time of publication.

Bug Bites in a Line: How to Identify and Treat
Different types of insects may leave bite marks that appear to follow a line. This can include fleas, bedbugs, and mites, among others. Treatment typically involves over-the-counter remedies. Bug bites can be an itchy nuisance, especially when you're bitten multiple times in a row by the same type of bug. Some insects, like flying insects, might bite one time and then move to their next victim. Other insects, though, may unleash several bites at once. And if you're on the other end of this attack, you might have a cluster of bites appearing in a line. What types of bugs cause these types of bites, though? Here's a look at different bugs that leave multiple bites in a row and how to treat them. Bug bites that appear in a line Different insects can leave different types of bite marks, including those appearing in a line. If you notice multiple bites in a row, there are a few possible culprits: Bug Bite description Symptoms Fleas Fleas can bite multiple times, leaving clusters of tiny red bumps in a row. Flea bites are often on the lower part of the body, such as on the legs, ankles, and feet. Symptoms include tiny red bumps or welts and extreme itching. Bedbugs Bedbug bites are red, appearing as a line of flat or raised bumps. Symptoms include itching, redness or other color changes, and swelling. Lice Head lice can cause a row of tiny red bumps around the head or neck. Lice can also leave a line of bumps near pubic hair, the hair around the armpits, or the eyebrows. Symptoms include intense itching that worsens at night and the appearance of tiny white eggs in the hair. Symptoms can appear up to 2 to 4 weeks after contact. Fire ants A single fire ant can bite multiple times, causing red bumps or lumps that appear in a line or in clusters. Symptoms include a burning, stinging sensation, itchiness, and swelling. Mites (scabies, chiggers, bird mites) Mites are insect-like organisms that can bite and cause skin irritation in humans. The bites are pimple-like rashes appearing in clusters or as raised lines on the skin. Symptoms include intense itching that worsens at night, redness or other color changes, and tingling and swelling around the bite site. Treating bug bites that appear in a line Bug bites can cause pain, redness, other color changes, and intense itching, so you'll want to take immediate action to relieve discomfort and prevent future bites. Identify and remove the culprit The first step in treating a bug bite is to identify the culprit. If you suspect a bedbug or flea infestation in your home, call a pest control company to find and remove the bugs. You can also prevent an infestation by treating fleas on your pets. Although irritating, most bug bites are minor and treatable with home remedies and over-the-counter (OTC) medications. Prevent swelling and infection For mild bites, wash the area with soap and water to prevent an infection. Apply a cool compress over the bite to reduce pain and swelling. If you have bites on your arms or legs, keeping this part of your body elevated can also reduce swelling. Soothe pain and itching Next, apply hydrocortisone cream or calamine lotion over the bite to calm itching, or take an OTC oral antihistamine. If you have pain, take an OTC pain reliever, such as ibuprofen or acetaminophen. Continue this treatment until symptoms go away. Treat lice and scabies with prescription topicals For lice If you have lice, you'll need an OTC medicated shampoo to kill the lice and their eggs. If these treatments don't work, ask your doctor for a prescription lice treatment. It's important to note that itching from lice doesn't go away immediately after treatment. Also, the initial treatment may not kill lice eggs. You may need to re-treat the area in a week, when the eggs have hatched. For scabies Treatment for scabies is a prescription antiparasitic topical cream. It will kill the mites and their eggs. Even after medication kills the mites, itching may last for a couple of weeks. To prevent reinfection, wash all your clothes, towels, and linen in hot water to kill the mites. About scabies bites The bite from a scabies mite isn't what itches. These pests burrow beneath the skin and leave their poop behind. The poop triggers an allergic reaction, which causes the itching and irritation. Should I see a doctor? A severe allergic reaction to a bug bite is a medical emergency. Seek immediate medical treatment if you develop any of the following symptoms: trouble breathing swollen lips or tongue rapid heartbeat chest pain headache vomiting dizziness Also, see a doctor if you're unable to identify a bug bite or if a bug bite doesn't heal or worsens in appearance. If your bite itches, keep in mind that scratching can break your skin and cause bacteria to penetrate the deeper level of your skin. This can lead to a bacterial skin infection called cellulitis. Signs of infection include: increased redness or other color changes pain blistering fever Don't wait for a fever! If you suspect you may have a bacterial skin infection, see a doctor right away. They can diagnose cellulitis early by looking for red streaks that extend away from the irritated area toward the heart. A thickening of the skin around the bite or wound is another indication of infection. Optum Perks is owned by RVO Health. By clicking on this link, we may receive a commission. Learn more.
