The immunity of upper airways.

A specialized immune system, called the nasopharynx-associated lymphoid tissue (NALT), is located on the mucosal surface of upper airways and is composed of both innate and specific immunity elements, closely related to each other and to the systemic defence, and spread over the nasopharynx, the nose and the middle ear. The NALT has a major role as regards to the infectious diseases of this area, which are the most common in children. It is also an interesting field of experimentation for new vaccine strategies in the future.

Urticaria and urticaria related skin condition/disease in children.

Urticaria is a rash, that typically involves skin and mucosa, and is characterized by lesions known as hives or wheals. In some cases there is an involvement of deep dermis and subcutaneous tissue that causes a skin/mucosa manifestation called angioedema. Urticaria and angioedema are very often associated: urticaria-angioedema syndrome.

Allergen specific nasal challenge to latex in children with latex allergy: clinical and immunological evaluation.

There are no data concerning the significance of allergen specific nasal challenge to latex (ASNCL) in the pediatric population and the effect of mometasone furoate nasal spray (MFNS), topic corticosteroid exerting a potent anti-inflammatory activity in children with latex allergic rhinitis. The aims of this study are: to investigate the clinical and immune pathological effects of ASNCL in children with latex allergy; to study the effects of MFNS pre-medication on the clinical and immune pathological effects of ASNCL in children with latex allergy. Thirteen children: 6 male and 7 female, mean (SD) age 9.

Systemic treatment of rhinosinusitis in children.

Systemic acute rhinosinusitis therapy consists mostly of antibiotic treatment because pathogens play a major role. Amoxicillin is the drug of choice for treatment of acute rhinosinusitis, with second- and third- generation cephalosporins, azythromycin, clarithromycin, and telithromycin as possible options, especially in the case of allergy to amoxicillin. If the clinical course suggests that an anaerobic pathogen is more likely, clindamycin or metronidazole can be considered in combination with a broad-spectrum drug.
