7/24/2015: Mosquiteos: how to prevent them from biting!
It is mosquito season as I sit on my porch watching these mini-vampires hover over me and my laptop. The problem with mosquito bites is:
Transmission of infections:
So, what are our options for preventing mosquitoes from biting us?
The Scientific data on treatments is scarce and most scientific studies have taken place in the laboratory as “arm in the cage” testing rather than in the field as a real life scenario.
Vitamin B1 (Thiamine): 100 mg (1000x the usual daily dose of Vitamin B1) of this water-soluble vitamin once a day can repel mosquitoes from biting for several hours. According to Stewart Harvey, PhD from Salt Lake City, “the repellent effect is attributed to a foul odor, undetected by humans, unless one smells the bottle. Biting insects, which are attracted by carbon dioxide, are repelled. Mosquitoes, deer flies, horse flies, and chiggers are repelled. It is not known whether arachnids are repelled, although deer ticks seem to be.” Some of the advantages are less expensive, does not rub off on clothes, well tolerated and non-oily. Thiamine might not properly enter the body in people who have liver problems or drink a lot of alcohol. An overdose of over 1000 mg of Vitamin B1 could lead to skin rash, allergic reaction, agitation, insomnia, or heart palpitations. The only study I found that showed Vitamin B1 did not work was published in 1969.
DEET (N,N-diethyl-3-methylbenzamide): This compound was developed by the U.S. Army after jungle warfare in WWII. For the past 60 years, this chemical has been effective and with a strong safety record. In an article from the New England Journal of Medicine in 2002, reports “DEET-based repellents remain the gold standard of protection under circumstances in which it is crucial to be protected against arthropod bites that might transmit disease.” The chemical is commonly found in mosquito repellents and the duration of action is directly correlated with the concentration. The higher the concentration, the longer the duration of action. The American Academy of Pediatrics advises against using repellents with DEET concentrations higher than 30% on any child.
DEET + Permethrin: For our U.S. military troops, the Department of Defense Insect Repellent System includes DEET-containing repellant applied directly to the skin and permethrin applied to the battle uniform. This prevents arthropod (insects and spiders) bites. The permethrin last longer when applied to the battle uniforms than onto the skin.
Picaridin: this synthetic compound repels insects, ticks and chiggers. It was first made available in the 1980s. It was made to resemble the natural compound piperine, which is found in the same group of plants that make black pepper. Picaridin has been widely used as an insect repellent in Europe and Australia, but only since 2005, has it been available in the U.S. Picaridin is available as pump spray, wipes, liquids and aerosols.

At Family Allergy Asthma & Sinus Care, our goal is to help prevent itching, including itching from bug and mosquito bites. I hope this information helps keep the pesky mosquitoes from dining on you!
Nickel. Allergic contact dermatitis from nickel affects 10-15% of the population worldwide. This type of allergy is called a Type IV T-cell mediated delayed-type hypersensitivity reaction. Nickel allergy is 2 to 6 times more common in women than men. It is also more common in younger individuals and those without pollen or food allergy. The skin reaction occurs at sites where the skin contacts nickel contained in many metals including:

Do beans agree with you? If not, read on. Beans are just one type of edible legume. Other well known legumes include alfalfa, clover, peas, lentils, lupins, mesquite, carob, soybeans, peanut, tamarind and the woody climbing vine wisteria.
While there are over 40,000 types of beans in the gene banks, a small number of bean varieties are used for human consumption. The common bean belongs to the genus/species Phaseolus vulgaris which includes pinto bean, kidney bean, black bean and green bean. Other common beans are the fava (broad) bean (Vicia faba), lima bean (Phaseolus lunatus), and chickpea or garbanzo bean (Ciser arietinum). Beans are an important source of protein and proteins are responsible for triggering allergies! Interestingly, as common as beans are in the human diet, allergic reactions are uncommon. Even though peanuts are legumes, in a U.S. study performed years ago, only 5% of children with a peanut allergy had allergic reactions to other beans tested.
In India and the Mediterranean, lentils and chickpeas have been reported to be the most common legume triggering allergic reactions in young children. Thankfully, no anaphylactic reactions were reported. Legume allergy, mainly to lentils and chickpeas, is the 5th most common cause of food allergy in Spanish children. In the U.S., severe bean allergy or anaphylaxis is rare or rarely reported.

Adverse reactions to beans:
Treatment for Bean Allergy:
As with other food allergies, identifying and avoiding the specific bean and those beans that are cross reactive is the primary approach. Being ready in case of an accidental exposure with self-injectable epinephrine is of paramount importance in those individuals at risk for anaphylaxis. Cooked beans can be more allergenic than raw beans and even bean protein inhaled from cooking fumes may trigger an allergic reaction such as asthma.
At Family Allergy Asthma & Sinus Care, we investigate a wide variety of food-induced allergic reactions. If you suspect you have had allergic reactions to beans (non-flatulent) or any other food, contact us, we can help!Do you sneeze when you sip that fine red wine? Wine allergy?
