Acute urticaria is the presence of urticaria for <6 weeks, and it is the most common type of urticaria in children. Sometimes, it may be associated with anaphylaxis, a life-threatening condition. Urticaria must be differentiated from anaphylaxis because the latter may require emergency treatment. We describe a child with anaphylaxis exposed to grasses on two occasions.
We described a 4-year-old male child with anaphylaxis exposed to grasses. Patient also suffered mild neurologic/respiratory symptoms but it is unlikely that he had anaphylaxis. Skin-prick tests were positive to . Little is known about the importance of pollens as a cause of urticaria in young children.
The case reported here is particularly interesting because, to the best of our knowledge, anaphylaxis due to pollen exposure in children aged <4 years has not been reported before. We strongly encourage all physicians searching for the cause of acute urticaria (allergists, dermatologists, primary-care physicians) to consider the possibility of pollen allergy, and to screen these patients for pollen sensitization.
急性荨麻疹是指荨麻疹病程小于6周，是儿童中最常见的荨麻疹类型。有时，它可能与过敏反应相关，这是一种危及生命的状况。必须将荨麻疹与过敏反应区分开来，因为后者可能需要紧急治疗。我们描述了一名两次接触草类后发生过敏反应的儿童。
我们描述了一名4岁男性儿童，他接触草类后发生过敏反应。患者还出现了轻度神经/呼吸症状，但他不太可能发生过敏反应。皮肤点刺试验对……呈阳性。关于花粉作为幼儿荨麻疹病因的重要性，人们了解甚少。
据我们所知，此前尚未报道过4岁以下儿童因接触花粉而发生过敏反应的情况，因此这里报告的病例特别有趣。我们强烈鼓励所有寻找急性荨麻疹病因的医生（过敏症专科医生、皮肤科医生、初级保健医生）考虑花粉过敏的可能性，并对这些患者进行花粉致敏筛查。
