ABSTRACT
La fibroelastosis pleuroparenquimatosa idiopàtica (FEPPI) es un trastorno raro incluido recientemente en las neumonías intersticiales idiopáticas según la actualización de la clasificación de la Sociedad Torácica Estadounidense (American Thoracic Society) y la Sociedad Respiratoria Europea (European Respiratory Society). La FEPPI se caracteriza por fibrosis parenquimatosa pleural y subpleural que produce reducción del volumen, sobre todo en los lóbulos pulmonares superiores. La edad al momento de la aparición varía, aunque la FEPPI ocurre principalmente entre los 30 y los 50 años de edad. En este artículo, presentamos el caso de un paciente de 16 años con antecedentes de disnea de esfuerzo, tos seca y pérdida de peso en los últimos dos años. Durante el examen físico, con la auscultación se detectó disminución de los ruidos respiratorios en los lóbulos superiores. En la radiografía de tórax se observó engrosamiento pleural apical y volumen reducido. En la tomografia computarizada (TC) del tórax se observaron densidades en vidrio esmerilado y bronquiectasia tubular predominantemente en ambos lóbulos superiores, con engrosamiento septal interlobulillar de la pleura y adenopatía mediastínica. Se realizó una biopsia pulmonar por toracoscopia y en el examen histológico se observaron fibrosis subpleural y tinción de las fibras elásticas que demostraba depósito de fibras elásticas en el área subpleural y el parénquima pulmonar adyacente, lo que sugería FEPPI. Hasta donde sabemos, este es el primer caso durante la niñez. Por lo tanto, los pediatras deben estar atentos a esta enfermedad para realizar un diagnóstico y tratamiento adecuados.
Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare disorder recently included in rare idiopathic interstitial pneumonias according to the updated American Thoracic Society/European Respiratory Society classification. IPPFE is characterized by pleural and subpleural parenchymal fibrosis causing volume loss predominantly in the upper lung lobes. Age of onset is variable, IPPFE mainly occurs in third and fourth decades. We present a 16 year old patient with a 2-year history of exertional dyspnea, nonproductive cough and weight loss. On physical examination, auscultation revealed diminished breath sounds on the upper lobes.Chest radiograph showed apical pleural thickening and volume loss. Computerized tomographic scan (CT) of chest revealed ground glass densities and tubular bronchiectasis predominantly in upper lobes bilaterally, with interlobular septal thickening of the pleura and enlarged mediastinal lymph nodes. Thoracoscopic lung biopsy was performed and histological evaluation showed subpleural fibrosis and elastic staining demonstrated fragmented elastic fiber deposition in the subpleural area and adjacent pulmonary parenchyma suggesting IPPFE. To our knowledge this is the first case in childhood. Therefore, pediatricians should be aware of this disease for the diagnosis and appropriate management.

Sarcoidosis is a systemic granulomatous disease of unknown etiology that may affect many systems, mainly lungs. Most of the patients present at stages I and II lung involvement. Pulmonary infltrates without hilar lymphadenopathy (state III) rarely occurs. Extrapulmonary organ involvement is common in pediatric sarcoidosis. The aim of this report is to present an unusual case of childhood sarcoidosis with stage III lung involvement without any extrapulmonary organ involvement. A 7-year-old girl presented with the complaints of malaise, fatigue, weight loss and dyspnea. There was patchy, bilateral ground glass view at high resolution computer tomography. Video assisted thoracoscopic lung biopsy was performed and histopathological examination showed nonnecrotising epitheloid-cell granulomas with giant cells. She did not have any hilar or extrapulmonary organ involvement and pulmonary sarcoidosis at stage III was diagnosed. Sarcoidosis should be considered in the differential diagnosis of children with interstitial lung disease.
La sarcoidosis es una enfermedad granulomatosa sistémica de etiología desconocida que puede afectar varios órganos, principalmente el pulmón. La mayoría de los pacientes presentan estadios I y II de compromiso pulmonar. Los infltrados pulmonares, sin linfadenopatías hiliares (estadio III), son infrecuentes. El compromiso de órganos extrapulmonares es común en la sarcoidosis infantil. El objetivo es presentar un caso infrecuente de sarcoidosis infantil con compromiso pulmonar en estadio III sin afectación de los órganos extrapulmonares. Una niña de 7 años consultó por malestar general, fatiga, pérdida de peso y disnea. En la tomografía computarizada de alta resolución se observó un infltrado bilateral de tipo esmerilado. Se realizó una biopsia pulmonar por videotoracoscopia. La histopatología mostró granulomas no necrosantes de células epitelioides con células gigantes. No había compromiso hiliar ni de otros órganos, por lo que el diagnóstico fue de sarcoidosis en estadio III. La sarcoidosis debe considerarse en el diagnóstico diferencial de los niños con enfermedad intersticial pulmonar.

Certain occupational groups are known to be at particularly high risk of developing allergic diseases. The objective of the present study was to evaluate the prevalence of allergic diseases among working adolescents. The International Study of Asthma and Allergies in Childhood questionnaire was used. Four hundred and thirty six adolescents working in motor, lathe-finish, coiffure and textile and 366 high school students as control group were enrolled to the study. Mean age was 16.8 ± 1.2 years and 82.9% of them were male. There was no significant difference among groups for ever and current wheezing while doctor diagnosed asthma was higher in lathe- finish group (p = 0.036). Family history of allergy, history of allergic rhinitis, and active smoking were found to be risk factors for asthma and related symptoms. Working in coiffure (p = 0.054), and textile (p = 0.003) were significant risk factors for ever allergic rhinitis. Working in lathe finish (p = 0.023), coiffure (p = .002), and textile (p < 0.001) were associated with a higher risk for current allergic rhinitis. Working in coiffure was a risk factor for ever eczema (p = 0.008) and doctor diagnosed eczema (p = 0.014). It was concluded that working in lathe-finish was associated with doctor diagnosed asthma and active smoking was a risk factor for asthma and related symptoms. Working in coiffure, textile and lathe- finish were risk factors for rhinitis, and working in coiffure was a risk factor for eczema. Preventive measures should be taken at the onset of employment in order to prevent or reduce the detrimental effects of exposures in these occupational groups.
