13. Paragonimiasis: first case reported in Brazil
The authors present a case from a 59 years old white female Brazilian patient, based in Salvador-Bahia, Brazil's northeastern side area, who experienced irritative cough and progressive dyspnea, and, after 18 months, was admitted to a hospital with respiratory insufficiency. The physical exam showed diffuse rales in both hemithoraces. Initial leukogram showe

14. Tomographic evaluation of the small airways in the interstitial lung diseases / Avaliação tomográfica do acometimento das pequenas vias aéreas nas doenças intersticiais do pulmão
The pathogenesis of idiophatic pulmonary fibrosis (IPF), the most common form of idiopathic interstitial pneumonias, is not completely understood. It is related to a type I pneumocyte injury with loss of basement membrane integrity and failure of normal re-epithelialization and re-endothelialization leading to fibroblast proliferation and extra cellular matr

15. Perfil celular do lavado broncoalveolar em crianças e adolescentes com asma de difícil controle / Bronchoalveolar lavage cell profile in children and adolescents with severe asthma
Therapy resistant asthma is a major clinical problem in childhood. We investigated the inflammatory cell profile in the airways of children with severe asthma despite systemic steroid treatment and the relationship with clinical and functional severity. Bronchoalveolar lavage (BAL) was performed in 24 children with severe asthma (13M/11F; mean age 12.5 yrs,

16. Função pulmonar de crianças e adolescentes infectados pelo virus da imunodeficiencia humana com pneumonia intersticial
BACKGROUND: Pulmonary compromise is observed in as much as 80% of human immunodeficiency virus (HIV)-infected children. Such compromise may be due to recurrent lung infections or specifically related to HIV, composing the pulmonary lymphoid hyperplasia / lymphoid interstitial pneumonitis (PLH/LIP) complex. This study aimed to evaluate physiological, clinical

17. PadrÃo regional de ventilaÃÃo pulmonar durante as tÃcnicas do Breathstacking e InspirÃmetro de Incentivo pela inalaÃÃo de radioaerossol
The sustained maximal inspiration (SMI) maneuver was utilyzed in oreder to improve ventilation through the incentive spirometries (IS). The breath-stacking (BS) technique which is an alternative to the IS and it does not require the patients acquaintance. The aim of this study was to analyze the regional pattern of the lung deposition, using the BS and IS te

18. Estudo da função das glandulas supra-renais em pacientes asmaticos em uso de beclometasona e fluticasona
Bronchial asthma is widely known as a chronic inflammatory disease of the airways and corticosteroids are the most effective drugs for asthma treatment since they block many of the inflammatory mechanisms of the disease and they have prophylactic action. In the last decades, with the introduction of inhaled corticotherapy, there was a reduction in the period

19. Small Airways in Idiopathic Pulmonary Fibrosis: COMPARISON OF MORPHOLOGIC AND PHYSIOLOGIC OBSERVATIONS
18 patients with idiopathic pulmonary fibrosis were studied to determine if they had morphologic evidence of small airways disease and if physiologic testing could predict morphologic findings. In the presence of normal airway function by standard physiologic studies (forced expiratory volume in 1 s/forced vital capacity and airway resistance by plethysmogra

20. Upper airway irritation and small airways hyperreactivity due to exposure to potassium aluminium tetrafluoride flux: an extended case report.
OBJECTIVES--22 workers, exposed to potassium aluminium tetrafluoride used as flux for soldering aluminium, were studied as clinical outpatients for symptoms of irritation of the nose, eye, skin, and airways. METHODS--16 volunteered for spirometry with methacholine provocation test including a test for small airways function by volume of trapped gas (VTG). RE

21. Small airway inflammation in asthma
Asthma was originally described as an inflammatory disease that predominantly involves the central airways. Pathological and physiological evidence reported during the past few years suggests that the inflammatory process extends beyond the central airways to the peripheral airways and the lung parenchyma. The small airways are capable of producing T-helper-

22. Severe diffuse small airways abnormalities in long term chrysotile asbestos miners.
To determine the nature and extent of pathological changes in the small airways induced by asbestos, the pathological lesions of fibrosis and pigmentation of the membranous and respiratory bronchioles and alveolar ducts in lungs obtained from necropy from a group of 36 non-asbestotic long term chrysotile miners and 36 age, sex, and smoking matched controls w

23. Airway disease in upper and lower lobes in lungs of patients with and without emphysema.
To determine whether pathological changes in the small airways are evenly distributed throughout the lung and whether there is an association of small airway disease with emphysema, pathological abnormalities of the small airways were graded in the upper and lower lobes of 13 surgical lung specimens. Except for slightly increased degrees of respiratory bronc

24. Beta-blockers in bronchial asthma: effect of propranolol and pindolol on large and small airways.
In 11 asthmatic subjects the relative magnitude and the site of airway bronchoconstriction were compared after the oral administration of 40 mg of propranolol and 2.5 mg of pindolol and the magnitude and site of bronchodilation produced by 0.5 mg subcutaneous terbutaline were tested after pretreatment with propranolol and pindolol.
