Unilateral pulmonary collapse in asthmatics. Five asthmatic patients developed collapse of one lung. Three of the patients were children and three of the five had repeated episodes of atelectasis. Episodes of atelectasis were usually associated with localised chest pain, which was not pleuritic in character, and with breathlessness, but without wheezing. They were not related to clinically apparent respiratory infections or to deterioration of the underlying asthma. The cause is obscure, but re-expansion seems to be hastened by oral corticosteroid therapy. Atelectasis is a well-recognised complication of lobe. Prick tests against common allergens includ- asthma.

  • Clarifying the Diagnosis of Post-Inflammatory Pulmonary Fibrosis: a Population-Based Study
    AGORA | RESEARCH LETTER Clarifying the diagnosis of post- inflammatory pulmonary fibrosis: a population-based study To the Editor: Epidemiological studies are important in defining the distribution and burden of diseases in a population. A common method of studying interstitial lung disease (ILD) epidemiology has been the analysis of insurance and billing claims databases, such as the Commercial Claims and Encounters Database and the Medicare Supplemental and Coordination of Benefits Database. These studies rely on the accuracy of International Statistical Classification of Diseases (ICD) codes to identify a patient population of interest. Several studies have described the incidence and prevalence of ILD by methodically searching ICD codes related to ILD or by using code-based algorithms [1–6]. Post-inflammatory pulmonary fibrosis (PPF) (ICD-9-CM 515) has been categorised as a general diagnostic code used by providers for IPF, an ILD characterised by progressive parenchymal fibrosis [1, 7]. Cases of PPF have been variably included in studies of IPF epidemiology. The prevalence of PPF may be comparable or higher to that of IPF. For example, COULTAS et al. [2] reported PPF to represent 16.7% of prevalent cases of ILDs while IPF comprised 22.5% in a population-based registry. RAGHU et al.[8] analysed a large healthcare claims database spanning the period 1996–2000 and found the prevalence of PFF to be nearly 11-fold higher than that of IPF identified by “broad case definition”. To our knowledge, however, cases designated as PPF have never been fully characterised. In particular, it is unknown to what extent PPF (ICD-9-CM 515) overlaps with the diagnosis of IPF.

    Allergic Bronchopulmonary Aspergillosis Karen Patterson1 and Mary E. Strek1 1Department of Medicine, Section of Pulmonary and Critical Care Medicine, The University of Chicago, Chicago, Illinois Allergic bronchopulmonary aspergillosis (ABPA) is a complex clinical type of pulmonary disease that may develop in response to entity that results from an allergic immune response to Aspergillus aspergillus exposure (6) (Table 1). ABPA, one of the many fumigatus, most often occurring in a patient with asthma or cystic forms of aspergillus disease, results from a hyperreactive im- fibrosis. Sensitization to aspergillus in the allergic host leads to mune response to A. fumigatus without tissue invasion. activation of T helper 2 lymphocytes, which play a key role in ABPA occurs almost exclusively in patients with asthma or recruiting eosinophils and other inflammatory mediators. ABPA is CF who have concomitant atopy. The precise incidence of defined by a constellation of clinical, laboratory, and radiographic ABPA in patients with asthma and CF is not known but it is criteria that include active asthma, serum eosinophilia, an elevated not high. Approximately 2% of patients with asthma and 1 to total IgE level, fleeting pulmonary parenchymal opacities, bronchi- 15% of patients with CF develop ABPA (2, 4).

University Claude Bernard Lyon I, University of Lyon, Lyon, France Semin Respir Crit Care Med 2012;33:462–475. Abstract Organizing pneumonia (OP) is a pathological pattern defined by the characteristic presence of buds of granulation tissue within the lumen of distal pulmonary airspaces consisting of fibroblasts and myofibroblasts intermixed with loose connective matrix. This pattern is the hallmark of a clinical pathological entity, namely cryptogenic organizing pneumonia (COP) when no cause or etiologic context is found. The process of intraalveolar organization results from a sequence of alveolar injury, alveolar deposition of fibrin, and colonization of fibrin with proliferating fibroblasts. A tremen- dous challenge for research is represented by the analysis of features that differentiate the reversible process of OP from that of fibroblastic foci driving irreversible fibrosis in usual interstitial pneumonia because they may determine the different outcomes of COP and idiopathic pulmonary fibrosis (IPF), respectively. Three main imaging patterns of COP have been described: (1) multiple patchy alveolar opacities (typical pattern), (2) solitary focal nodule or mass (focal pattern), and (3) diffuse infiltrative opacities, although several other uncommon patterns have been reported, especially the reversed halo sign (atoll sign).

  • Bronchiectasis
    Bronchiectasis By L. D. Eerland and N. G. M. Orie With 58 Figures A. Introduction~ Definition and Historical Survey 1. Introduction One of the most intricate fields of pulmonary pathology is that of the aetiology and pathogenesis of bronchiectasis. Much has remained unexplained, in spite of the extensive literature that has appeared since LAENNEC first described the affection in 1817. There are still many questions unanswered as regards the indications for operative treatment and the results obtained by surgery. At present there is no Ionger any difficulty in the diagnosis of bronchiectasis, espe­ cially owing to the development of bronchography, eventhough it should be remarked that technically perfect bronchograms are required to arrive at a therapeutically justi­ fied plan of campaign. l<'ig. I. Dorsoventral bronchogram of 4-year-old boy, who had a so.called left pneumonia four months previously. There is a considerable displacement of the mediastinum.

This was a case of reversible bronchiectasis, as shown by Fig. 2 It must be admitted that the sulphonamides and modern antibiotics have been of inestimable value during the pre- and after-treatment of patients in whom resection of the diseased parts of the lung has been carried out. It is however doubtful whether parenteral or intratracheal administration of these agents alone yields lasting results. An operation is therefore often necessary, but, unfortunately, complete success is not always obtained with pulmonary resection, the only operation that comes into consideration.
