Mosquito biteT14.0
DefinitionThis section has been translated automatically.
Sting through mosquitoes.
Clinical featuresThis section has been translated automatically.
At the puncture site (uncovered skin areas) a differently sized, very itchy wheal develops with a punctiform, often haemorrhagic puncture site: transformation into a still itchy, strongly reddened papule, possibly blistering. Allergic system reactions ( urticaria) are only to be expected in the case of a high degree of sensitization. In rare cases, excessive reactions with disturbances of the general findings (possibly fever) as well as severe erythema exsudativum multiforme-like or erythema nodosum-like local reactions may occur. In these cases an EBV infection with NK-cell lymphocytosis must be clarified.
DiagnosisThis section has been translated automatically.
Clinic, in particular sensitization RAST and prick test for mosquitoes.
Complication(s)This section has been translated automatically.
Secondary infections.
External therapyThis section has been translated automatically.
- In the case of minor symptoms, application of a topical antihistamine (e.g., Fenistil gel, Soventol gel) or a 1% menthol solution or a 1% hydrocortisone lotion (e.g., Hydrogalen lotion/Lsg.).
- In case of pronounced symptoms, short-term application of a potent glucocorticoid, e.g. mometasone f uroate (Ecural), and cooling moist compresses (e.g. Tannolact).
- local heat application, in the sense of local hyperthermia at 50 ° C. Devices such as bite away® are available on the market.
- Currently grid tapes or cross tapes (e.g. Moskinto mosquito patches) are used: stick on the not yet scratched skin. Currently not yet scientifically recognized. Mesh tapes are known from acupuncture, where they are stuck on the acupuncture points instead of needles. Regarding the mechanism of action, one thinks on the one hand of minimal skin irritations by the rigid grid plaster during movements, on the other hand of electrostatic stimuli.
Internal therapyThis section has been translated automatically.
In the case of a large number of stitches, internal antihistamines such as desloratadine (e.g. Aerius) 1 tbl/day or levocetirizine (e.g. Xusal) 1 tbl/day.
ProphylaxisThis section has been translated automatically.
Rubbing with repellents (e.g. Autan).
