 How many of you have complained that you feel your lips or mouth tingling after eating some fruits or vegetables?
If you also suffer from Hayfever, we are talking about Oral Allergy Syndrome, also known as Pollen Food Syndrome. 𝗪𝐡𝐚𝐭 𝐢𝐬 𝐢𝐭 𝐭𝐡𝐞𝐧? This is an allergic reaction, with swelling and itchiness, affecting the mouth, lips, tongue, and throat only. Usually, the symptoms are seen within a few minutes of eating certain fruits and vegetables, mainly when they are raw. It is not common to cause swelling of the throat. Even less common to cause anaphylaxis. 𝗪𝐡𝐲 𝐝𝐨𝐞𝐬 𝐭𝐡𝐢𝐬 𝐡𝐚𝐩𝐩𝐞𝐧? Some proteins in foods are similar to some of the proteins found in certain pollens, so a cross-reaction might occur. That is also why it is called Pollen Food Syndrome. 𝗪𝐡𝐞𝐧 𝐜𝐚𝐧 𝐬𝐲𝐦𝐩𝐭𝐨𝐦𝐬 𝐬𝐭𝐚𝐫𝐭? For a child to suffer from hayfever, they usually need to be exposed to 2 pollen seasons. For Oral Allergy Syndrome to develop, they need to be exposed to the food causing the reaction, many times. This means it is not common to find it in toddlers. 𝐒𝐨 𝐢𝐭 𝐦𝐚𝐢𝐧𝐥𝐲 𝐚𝐟𝐟𝐞𝐜𝐭𝐬:
This type of symptoms are not associated only with the pollen season, this as we can find those foods available throughout the year. Saying this, symptoms usually are higher when the pollen count is also higher. 𝗪𝐡𝐚𝐭 𝐚𝐫𝐞 𝐭𝐡𝐞 𝐦𝐨𝐬𝐭 𝐜𝐨𝐦𝐦𝐨𝐧 𝐩𝐨𝐥𝐥𝐞𝐧𝐬 𝐰𝐞 𝐧𝐞𝐞𝐝 𝐭𝐨 𝐥𝐨𝐨𝐤 𝐟𝐨𝐫, 𝐭𝐨 𝐬𝐚𝐲 𝐭𝐡𝐞𝐫𝐞 𝐢𝐬 𝐚 𝐜𝐨𝐧𝐧𝐞𝐜𝐭𝐢𝐨𝐧? 𝘛𝘳𝘦𝘦𝘴

Caution as in the case of roasted hazelnuts and cooked celeriac, in some cases, minute amounts of the protein might still cause symptoms in highly sensitized patients. There is also the possibility that immunotherapy directed at the pollen involved in the cross-reaction, might lead to a decrease of symptoms. After having a diagnosis made (and this is one of the reasons component diagnostics are needed), a dietitian's cooperation is required, so appropriate follow-up and plan to introduce other foods that are closely related to the one initially the patient reacted to. If your child has a reaction, the best course of action is:

 The incidence of peanut allergy has been increasing significantly in developed countries.
Many reasons have been found for such growth, but so far no proper treatment has been found to deal with it. Often, antihistamines are the first choice when there is an allergic reaction, with the occasional need to use adrenaline as well. Most of the symptoms start in childhood and persists throughout life. Due to this, the search for ways to deal with this specific allergy is ongoing, though not matching current needs. As such, today, I will focus on a promising medication that might lead to a significant change in the way we deal with peanut, and possibly, tree nut allergy. On a Phase 2a randomized placebo control trial, running for six weeks, a single injection of Etokimab showed that it could desensitize peanut allergic adults.
They concluded that it could potentially desensitize peanut-allergic participants and possibly reduce atopy-related adverse events. I understand the first part, but what is the connection to atopy? Let me explain.
Can you see me coming again to the top priority of maintaining the skin barrier to prevent allergy? My opinion about it:
How does it compare to the current two available oral peanut immunotherapy? CA002 (Cambridge) and AR101 (London)

The name Allergic Rhinitis wasn't used until the 20th Century.
The name "Allergic Rhinitis" is the true name of this pathology. Allergic due to the reaction being made by allergens. Rhinitis is due to the combination of two Greek words:
The main cause, aroud Spring and Summer, is Pollen. Being it from Trees or from Grasses. But Allergic Rhinits can also be due to other airborne allergens. Such as:
On its own, it is not life threatening. The main problem is when associated with poorly or uncontrolled asthma. Can also be troublesome for sufferers of Pollen Food Syndrome/Oral Allergy Syndrome. The most common symptoms are:
Skin prick tests are the main source for diagnosis. Blood tests can eventually be done, mainly in primary care. What to do:
