ABSTRACT
BACKGROUND: Local allergic rhinitis (LAR) is a condition involving a localized nasal allergic response in absence of systemic atopy. Most studies on LAR have been performed in adults. We aimed to describe clinical characteristics of LAR pediatric patients, its clinical evolution over a 7-year follow-up period and to study the role of basophil activation test (BAT), for its diagnosis. METHODS: Forty-four children with non-allergic rhinitis (NAR) were included (24 males, 20 females, aged under 15 years). Nasal allergen provocation test (NAPT) and BAT were performed with Dermatophagoides pteronyssinus and Phleum pratense. RESULTS: Seven patients (16%) were diagnosed of LAR. Six reacted to D pteronyssinus and one to P pratense. All LAR and 86% of NAR patients presented perennial symptoms. Fifty-seven percent of NAR and LAR patients referred persistent symptoms. Around half of NAR and LAR patients reported mild-moderate clinical manifestations. Three LAR patients associated conjunctival symptoms, proportionally more than NAR patients (19%, 7 out of 37). NAR patients presented bronchial asthma (n = 10) more frequently than LAR children (n = 1). More than half of LAR and NAR patients presented family history of atopy. BAT was negative in all LAR patients. On follow-up, 3 LAR patients and 10 of the 25 NAR patients who agreed to be retested, presented systemic sensitization. Dust mites were the most frequent allergen involved. CONCLUSIONS: LAR should be ruled out in children with NAR. Almost half of children with LAR develop systemic sensitization over time. BAT shows low sensitivity for the diagnosis of LAR in children.

Durante los últimos años, la aplicación del vendaje neuromuscular (VN) ha sido empleada en el ámbito deportivo y la rehabilitación. Varios son los beneficios asociados al VN, aunque su influencia y efectos en el patrón de presión plantar es desconocida. En este sentido, mediante el sistema de pedobarografía Biofoot IBV® 6.0 se ha analizado la presión plantar en 5 zonas del pie, así como la cadencia y el tiempo de apoyo. Veintinueve sujetos participaron en el estudio, caminando sobre una cinta rodante a 1 m/s, con/sin VN en peroneos y tríceps sural. Los resultados no mostraron diferencias significativas (p<0,05) en las presiones plantares por el uso del VN en ambos grupos musculares. Tan sólo el efecto de este vendaje aplicado en el tríceps sural durante la marcha mostró un ligero incremento en el tiempo de apoyo (p=0,045) (AU)
Application of the neuromuscular bandage has frequently been used in sports and rehabilitation. There are several benefits associated with this bandage, although its influence and effects on the plantar pressure pattern have not been analyzed. In this sense, our study has analyzed plantar pressure in 5 foot zones with the pedobarographic system Biofoot IBV® 6.0 as well as cadence and contact time. A total of 29 subjects participated in the study, walking on a treadmill at 1 m/s with and without the neuromuscular bandage on the peroneus and triceps surae. The results did not show any significant differences (p<0.05) in plantar pressure using the neuromuscular bandage in both muscle groups. Only the effect of this bandage applied on the triceps surae during walking showed a slight increase in contact time (p=0.045) (AU)
