The direct toxicity of cigarette smoke and the body's subsequent response to this lung injury leads to a wide array of pathologic manifestations and disease states that lead to both reversible and irreversible injury to the large airways, small airways, alveolar walls, and alveolar spaces. These include emphysema, bronchitis, bronchiolitis, acute eosinophilic pneumonia, pulmonary Langerhans cell histiocytosis, respiratory bronchiolitis, desquamative interstitial pneumonia, and pulmonary fibrosis. Although these various forms of injury have different pathologic and imaging manifestations, they are all part of the spectrum of smoking-related diffuse parenchymal lung disease...

OBJECTIVES: Recent literature suggests that bedside lung ultrasound may have a role in the evaluation of infants with bronchiolitis. B lines, which are multiple and diffuse vertical artifacts spreading from the lung pleural interface to the edge of the ultrasound screen, have been associated with thickened interlobular septa, extravascular lung water, and diffuse parenchymal disease. The aims of this study were (1) to describe the prevalence of B lines in children younger than 24 months presenting to the emergency department with wheezing, (2) to determine the interrater reliability of lung ultrasound findings in this setting, and (3) to determine the association of B lines with atopy and other clinical findings...

BACKGROUND: Diagnostic evaluation of patients with diffuse parenchymal lung disease (DPLD) is best achieved by a multidisciplinary team correlating clinical, radiologic, and pathologic features. Surgical lung biopsies remain the gold standard for histopathologic diagnosis of idiopathic interstitial pneumonias. Emerging data suggest an increasing role for transbronchial cryobiopsy (TBC) in DPLD evaluation. We describe our experience with TBC in patients with DPLD. METHODS: We retrospectively reviewed medical records of patients with radiographic features of DPLD who underwent TBC at Mayo Clinic, Rochester, Minnesota in June 2013-September 2015...

The incidence of tuberculosis is increasing in the developed world and children in particular represent a high-risk group for developing the disease. The aim of this review is to analyse the spectrum of radiological signs as reported in the recent literature, in light of our series over a 15-year period, to pinpoint the most common radiological patterns in a developed country and to determine the role played by the different chest imaging techniques in diagnosis improvement. Lung TB was present in 217 out of 255 patients (85 %): 146 patients were under 5 years of age (76 under 2 years) and 71 over 5 years (41 over 10 years)...

A 42-year-old housewife, the resident of rural part of West Bengal, presented with gradually progressive exertional dyspnea associated with a dry cough for last 3 years clinical features were suggestive of diffuse parenchymal lung disease (DPLD). Her chest X-ray posteroanterior view and high resolution computed tomography scan of the thorax showed bilateral patchy ground glass opacities and reticulonodular pattern. Search for the etiology revealed classical skin findings of chronic arsenic exposure in the form of generalized darkening and thickening of skin and keratotic lesions over the palms and soles and classical raindrop pigmentation over leg which was present for last 7 years subsequently her bronchoalveolar lavage fluid, hair, nail, and drinking water showed significant amount of arsenic contamination...

OBJECTIVES: Pulmonary hypertension (PH) is commonly observed in patients with diffuse parenchymal lung disease (DPLD). The purpose of this study was to explore the influence of the 6-minute walk test (6MWT) as a simple, non-invasive tool to assess right ventricular (RV) function in patients with DPLD and to identify the need for an echocardiogram (ECHO) to screen for PH. METHODS: We retrospectively reviewed 48 patients with PH secondary to DPLD, who were evaluated in the PH clinic at the Mayo Clinic in Jacksonville, Florida, from January 1999 to December 2014...

RATIONALE, AIMS, AND OBJECTIVES: The 6-minute walk test (6MWT) is widely used as a test of functional exercise capacity. Several studies have reported the minimal clinically important difference (MCID) for the 6MWT; however, the findings of the studies have not been examined in the context of one another. In this review, we aimed to summarize available information on the MCID for the 6MWT performed by patients with pathology. METHODS: Relevant literature was identified by searches of 3 electronic databases (PubMed, Scopus, and Cumulative Index of Nursing and Allied Health), examination of article reference lists, and consultation with an expert...

Cell-derived microparticles are small (0.1-1 μm) vesicles shed by most eukaryotic cells upon activation or during apoptosis. Microparticles carry on their surface, and enclose within their cytoplasm, molecules derived from the parental cell, including proteins, DNA, RNA, microRNA and phospholipids. Microparticles are now considered functional units that represent a disseminated storage pool of bioactive effectors and participate both in the maintenance of homeostasis and in the pathogenesis of diseases. The mechanisms involved in microparticle generation include intracellular calcium mobilisation, cytoskeleton rearrangement, kinase phosphorylation and activation of the nuclear factor-κB...

Restrictive lung diseases are a heterogeneous group of conditions characterized by a restrictive pattern on spirometry and confirmed by a reduction in total lung volume. Patients with more severe symptoms may have a reduced diffusing capacity of the lung for carbon monoxide. Etiologies can be intrinsic with lung parenchymal involvement, as in interstitial lung diseases, or extrinsic to the lung, as in obesity and neuromuscular disorders. Idiopathic pulmonary fibrosis is a chronic progressive interstitial pneumonia with fibrosis for which treatment is primarily supportive with oxygen therapy, pulmonary rehabilitation, and management of comorbid conditions...

Pulmonary hypertension (PH) due to chronic respiratory disease and/or hypoxia is classified as World Health Organization (WHO) Group III pulmonary hypertension. The patients most commonly encountered in clinical practice with group III PH include those with chronic obstructive lung disease (COPD), diffuse parenchymal lung disease, and sleep-disordered breathing. The purpose of this review is to outline the variable clinical significance of pulmonary hypertension in the most common pulmonary disease states and how a clinician may approach the management of these patients...

Pulmonary hypertension (PH) can be triggered by any number of disease processes that result in increased pulmonary vascular resistance. Although historically associated with idiopathic pulmonary arterial hypertension (iPAH), the majority of patients with PH do not have the idiopathic subtype, but rather PH associated with another underlying diagnosis, such as left heart or lung disease. The World Health Organization (WHO) classification of PH helps conceptualize the different categories based on presumed etiology...

BACKGROUND: The purpose of this study was to evaluate the use of high-resolution chest computed tomography (HRCT) to distinguish hypersensitivity pneumonitis (HP) from other diffuse parenchymal lung diseases (DPLDs). METHODS: We examined 130 consecutive patients admitted to our hospital with DPLDs proved by HRCT. Patients underwent clinical and paraclinical examinations. Two readers interpreted 111 HRCT scans using predefined criteria. RESULTS: The findings in patients with HP were compared to those with other DPLDs (non-HP) by univariate and multivariate analyses...

The parenchymal lung diseases caused by metal inhalation include interstitial fibrosis, giant cell interstitial pneumonitis, chemical pneumonitis, and granulomatous disease, among others. We reported two cases of granulomatous lung disease with occupational exposure to metal dusts other than beryllium. They had worked in the battery manufacturing industry for 7 years and in an aluminum-processing factory for 6 years, respectively. Chest high-resolution computed tomography showed diffuse micronodules, and histology of video-assisted lung biopsy specimens revealed granulomatous lesions in the pulmonary interstitium...

PURPOSE: The aim of the study was to determine whether a novel computed tomography (CT) postprocessing software technique (CALIPER) is superior to visual CT scoring as judged by functional correlations in idiopathic pulmonary fibrosis (IPF). MATERIALS AND METHODS: A total of 283 consecutive patients with IPF had CT parenchymal patterns evaluated quantitatively with CALIPER and by visual scoring. These 2 techniques were evaluated against: forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), diffusing capacity for carbon monoxide (DLco), carbon monoxide transfer coefficient (Kco), and a composite physiological index (CPI), with regard to extent of interstitial lung disease (ILD), extent of emphysema, and pulmonary vascular abnormalities...

BACKGROUND AND OBJECTIVE: Transbronchial cryobiopsy (TBCB) is a technique in which frozen samples of lung are obtained using a probe inserted through a bronchoscope. We performed a retrospective study to assess the performance of the TBCB procedure complemented by segmental bronchial blockade using an angioplasty balloon, in terms of diagnostic yield and safety in diffuse parenchymal lung disease (DPLD). METHODS: Data from 100 patients with suspected DPLD (clinical and radiological findings), who underwent TBCB in our institution to establish a definitive diagnosis, were reviewed...

Significant progress has been made in elucidating the genetics of parenchymal lung diseases, particularly idiopathic interstitial pneumonias (IIPs). IIPs are a heterogeneous group of diffuse interstitial lung diseases of uncertain etiology, diagnosed only after known causes of interstitial lung disease have been excluded. Idiopathic pulmonary fibrosis is the most common IIP. Through candidate gene approaches and genome wide association studies, much light has been shed on the genetic origins of IIPs, enhancing our understanding of risk factors and pathogenesis...

UNLABELLED: The aim of this manuscript is to describe radiological findings of extra-pulmonary sarcoidosis. Sarcoidosis is an immune-mediated systemic disease of unknown origin, characterized by non-caseating epitheliod granulomas. Ninety percent of patients show granulomas located in the lungs or in the related lymph nodes. However, lesions can affect any organ. Typical imaging features of liver and spleen sarcoidosis include visceromegaly, with multiple nodules hypodense on CT images and hypointense on T2-weighted MRI acquisitions...

BACKGROUND: Diffuse parenchymal lung disease represents a diverse and challenging group of pulmonary disorders. A consistent diagnostic approach to diffuse parenchymal lung disease is crucial if clinical trial data are to be applied to individual patients. We aimed to evaluate inter-multidisciplinary team agreement for the diagnosis of diffuse parenchymal lung disease. METHODS: We did a multicentre evaluation of clinical data of patients who presented to the interstitial lung disease unit of the Royal Brompton and Harefield NHS Foundation Trust (London, UK; host institution) and required multidisciplinary team meeting (MDTM) characterisation between March 1, 2010, and Aug 31, 2010...
