Neuroblastoma (NB) is the most frequently diagnosed neoplasm during infancy and its incidence declines within the first 3-5 years of life. It can be rarely diagnosed in adolescents and young adults. Adolescents have advanced stage of disease, higher frequency of uncommon metastatic sites such as lungs, and worse outcomes. Herein, we describe an unusual case of NB in a 17-year-old adolescent presented with lung metastasis at diagnosis. The patient was diagnosed with stage IV NB. Thorax high-resolution computed tomography (HRCT) scan revealed irregular septal thickening with ground glass opacity consistent with pulmonary parenchymal metastases...

RATIONALE: Sputum neutrophil elastase and serum desmosine, a linked marker of endogenous elastin degradation, are possible biomarkers of disease severity and progression in bronchiectasis. This study aimed to determine the association of elastase activity and desmosine with exacerbations and lung function decline in bronchiectasis. METHODS: This was a single-centre prospective cohort study using the TAYBRIDGE registry in Dundee, UK. 433 patients with HRCT-confirmed bronchiectasis provided blood samples for desmosine measurement and 381 provided sputum for baseline elastase activity measurements using an activity based immunosassay and fluorometric substrate assay...

INTRODUCTION: Congenital inner ear malformations occur as a result of the arrest or aberrance of inner ear development due to the heredity, gene mutation or other factors. Ever since the availability of cochlear implants, pre-operative evaluation by imaging of temporal bone has gained much attention. Precise selection of the candidate for cochlear implant dependent on preoperative radiological investigations. Only CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) can provide a better picture of anatomy and pathology...

BACKGROUND: The relationship between the histological pattern and survival in systemic sclerosis-associated interstitial lung disease (SSc-ILD) is unclear. In patients with SSc-ILD, we investigated whether the clinical data obtained by non-invasive examinations could be used for prognostic evaluation, and attempted to clarify whether complicating acute exacerbation (AE) and the selection of pharmacological therapy were associated with survival. METHODS: Thirty-five patients with SSc-ILD, who had not been diagnosed by surgical lung biopsy were analyzed, retrospectively...

BACKGROUND: Current data have shown that lung ultrasound (LUS) may be useful in the detection of interstitial lung disease (ILD) by the evaluation of B-lines, the sonographic marker of pulmonary interstitial syndrome. Nevertheless, no prospective study has compared LUS to chest X-ray (CXR) for ILD assessment, and there is no general agreement on the specific echographic diagnostic criteria for defining ILD. OBJECTIVES: The aims of this study were (1) to compare the accuracy of LUS and CXR in the detection of ILD using high-resolution CT (HRCT) as the gold standard and (2) to compare the accuracy of different echographic diagnostic criteria for ILD diagnosis...

Background and Objectives: Idiopathic pulmonary fibrosis (IPF) is a progressive, irreversible, invariably fatal fibrotic lung disease with no lasting option for therapy. Mesenchymal stem cells (MSCs) could be a promising modality for the treatment of IPF. Aim of the study was to investigate improvement in survivability and anti-fibrotic efficacy of human adipose-derived mesenchymal stem cells (AD-MSCs) in comparison with pirfenidone in the bleomycin-induced pulmonary fibrosis model. Methods: Human AD-MSCs were administered intravenously on day 3, 6 and 9 after an intra-tracheal challenge with bleomycin, whereas, pirfenidone was given orally in drinking water at the rate of 100 mg/kg body weight three times a day daily from day 3 onward...

There is a strong relationship between tobacco smoking and pulmonary Langerhans cell histiocytosis (LCH) in adults. Definitive diagnosis relies on lung histology. In certain cases, the diagnosis can be retained on a typical nodulo-cystic pattern on lung high-resolution computed tomography (HRCT) and appropriate clinical setting. The main differential diagnoses to consider vary according to nodulo-cystic or only cystic pattern on lung HRCT and the clinical context. The natural history of the disease is better known and regular evaluation of respiratory function is essential during the follow-up of the patients...

INTRODUCTION: Patients with non-small cell lung cancer (NSCLC) and interstitial lung disease (ILD) are at high risk of acute exacerbation of ILD (AE-ILD) when treated with systemic chemotherapy. Standard treatment for NSCLC complicated by ILD has not been established. PURPOSE AND METHODS: To examine whether the type of ILD categorized by the official ATS/ERS/JRS/ALAT statement as "idiopathic pulmonary fibrosis (IPF) by high-resolution computed tomography (HRCT)" could predict chemotherapy-induced AE-ILD in NSCLC patients with ILD, we retrospectively reviewed all patients with NSCLC complicated by ILD who had received chemotherapy at our institute from January 2007 until December 2013...
