Less commonly (around 10% of Hymenoptera sting reactions), a large local reaction occurs when the area of swelling is greater than 10 centimetres (4 in). Rarely (1-3% of Hymenoptera sting reactions), systemic reactions can affect multiple organs and pose a medical emergency, as in the case of anaphylactic shock. [2] [3]
Insect sting allergy is the term commonly given to the allergic response of an animal in response to the bite or sting of an insect. [1] Typically, insects which generate allergic responses are either stinging insects ( wasps , bees , hornets and ants [ 2 ] ) or biting insects ( mosquitoes , ticks ).
The mechanism of the described attack is still undetermined, but the victim was possibly abnormally susceptible to vespine stings. Currently, the two most effective treatments for reactions are electrical cardioversion or propafenone. The victim in this case study was given an oral dose of propafenone (150 mg) and his atrial fibrillation resolved.
Two years later, another was found in British Columbia and across the Canada-U.S. border in Washington State, but the species “seems to have vanished due to no detections in 2023 and 2024 ...
The concerned toddler wasted no time taking care of her mom's injury.
With insect stings, a large local reaction may occur in the form of an area of skin redness greater than 10 cm in size that can last one to two days. [31] This reaction may also occur after immunotherapy. [32] The way our body responds to foreign invaders on the molecular level is similar to how our allergens are treated even on the skin.
A 2004 study from Johns Hopkins University found that, unless they’d received allergy treatments for bee stings, a significant percentage of those who’d had severe reactions to bee stings as ...
The stings of the Asian giant hornet (V. mandarinia) are among the most venomous known, [10] and are thought to cause 30–50 human deaths annually in Japan. Between July and September 2013, hornet stings caused the death of 42 people in China. [12] Asian giant hornet's venom can cause allergic reactions and multiple organ failure leading to ...
