[Systemic mastocytosis with skin manifestation versus indolent mastocytosis]. / Mastocitosis sistémica con afectación de piel versus mastocitosis indolente.

We have analyzed the clinical, analytical, radiologic, therapeutic an evolutive of cases of systemic mastocytosis (SM) skin lesions. The diagnostic of MS is difficult in the absence of skin lesions.

Mastocitosis sistémica con afectación de piel versus mastocitosis indolente / Systemic mastocytosis with epidermis manifestation opposite to indolent mastocytosis

El objetivo de trabajo es la presentación de los datos clínicos, analíticos, radiológicos, terapéuticos y de evolución de un caso de matocitosis sistémica (MS) con afectación de piel. Revisando la literatura ya que la mastocitosis sigue siendo una enfermedad de difídicl diagnóstico, sobre todo en los casos que no existen alteraciones cutáneas (AU)

International Study of Asthma and Allergies in Childhood. Results on rhinitis of first phase in Pamplona, Spain.

BACKGROUND: The ISAAC (International Study of Asthma and Allergies in Childhood) was thought in order to maximize the value of epidemiological research into asthma and allergic diseases in childhood, establishing a standardized methodology and facilitating collaboration and comparison between several countries. METHODS AND RESULTS: The written questionnaires in the group of children aged 6-7 years was answered by the parents and the group of children aged 13-14 years self-completed the written questionnaires. RESULTS: 3,040 children aged 13-14 years answered the questionnaire and 3,002 in the group aged 6-7 years. In the group of children aged 13-14, 49.7% referred rhinitis symptoms some time, and 15.6% in the 6-7 year old group. The prevalence of nasal symptoms in the last year was 35.5% in the 13-14 year group and 10.6% in the 6-7 year group. The presence of nasal symptoms was more frequent in winter. The prevalence of seasonal allergic rhinitis (hay fever) was 6.1% in the 13-14 year group and 4.8% in the group of children aged 6-7 years. CONCLUSIONS: These results can contribute to a better control of some factors and to future studies where the etiology and incidence of the disease could be investigated.

Introducción: la rinitis alérgica es una patología frecuente en la infancia y en las tres últimas décadas ha ido aumentando de manera significativa. Por otra parte, es una manifestación temprana de predisposición atópica que puede ser exacerbada por exposición a alergenos y puede preceder al asma bronquial. Los estudios epidemiológicos ponen de manifiesto el incremento en la prevalencia de las enfermedades alérgicas. El proyecto ISAAC ha sido ideado para maximizar el valor de los estudios epidemiológicos en el asma y enfermedades alérgicas en la infancia, estableciendo un método de cuestionario capaz de facilitar la colaboración entre países.Métodos y Resultados: fueron encuestados un total de 3.040 niños de entre 13-14 años y 3.002 niños de 6-7 años. En los niños de 6-7 años, los cuestionarios fueron contestados por los padres y en los de 13-14 años, por los propios niños.Síntomas de rinitis alguna vez, refirieron el 49,7 por ciento de los niños de 13-14 años frente al 15,6 por ciento de los niños de 6-7 años. La prevalencia de síntomas nasales en el último año es de 35,5 por ciento en los de 13-14 años y 10,6 por ciento en 6-7 años. Es más frecuente la presencia de síntomas nasales en invierno, y la prevalencia de rinitis estacional fue de 6,1 por ciento en los niños de 13-14 años frente a un 4,8 por ciento en los de 6-7 años.Conclusiones: el conocer la prevalencia de rinitis en nuestro medio contribuye a un mejor control de determinados factores, y a la realización de futuros estudios en los que podamos investigar etiología e incidencia que nos aclaren el curso natural de la enfermedad.

[Dermatomyositis. Clinico-histologic study of its skin manifestations]. / Dermatomiositis. Estudio clínico-histológico de sus manifestaciones cutáneas.

The clinical and pathological findings in five patients with dermatomyositis are described. The diagnostic value of the cutaneous lesions in the disease, indicating the histological patterns of each cutaneous sign is stressed. Based in our experience and in the reviewed literature, we consider that Gottron's papules and poikilodermatomyositis present histological aspects that allow us to confirm the diagnosis suspected by clinical findings. Likewise we review some special difficult aspects of the disease such as infantile forms, association with neoplasias and overlap syndromes.
