ReviewTopical nasal lysine aspirin in aspirin-sensitive and aspirin-tolerant chronic rhinosinusitis with nasal polyposis.
Chronic rhinosinusitis patients with nasal polyps can be aspirin sensitive or aspirin tolerant. The majority belong to the latter group. They tolerate intake of aspirin or other non-steroidal anti-inflammatory drugs, whereas aspirin-sensitive patients have an adverse reaction (asthma, rhinitis and/or urticaria). ⋯ Any adjunctive therapy to prevent or prolong recurrence would be welcome. One such possibility is topical nasal lysine-aspirin. This is an area under current debate and this non-systematic review aims to provide evidence of its use, to date, in aspirin sensitive and aspirin tolerant nasal polyp patients.

Egg allergy is the second most frequent food allergy in children of the Western Countries, with an overall prevalence of 1-3%. Today strict avoidance diet is the only treatment, but its feasibility is difficult to obtain in childhood because of the large amount of egg proteins present in different foods. From 1998, a growing number of protocols on immunotherapy for egg allergy have been published, but all of them differ for patients' age, inclusion of high-risk patients, amount of allergen administered, duration of the protocols and presence of a control group. We reviewed the protocols performed in the last 15 years, to underline the most important issues in this kind of food immunotherapy, and the rates of tolerance or desensitization induction.
