Diagnostics and acknowledgement of occupational diseases - topics and challenges in the Czech Republic.

Cas Lek Cesk 2019 ;157(8):396-399

The causes of occupational diseases are changing, thats why a regular update of Czech List of Occupational Diseases is needed. New compensable occupational diseases, such as cancer of the larynx and ovarian cancer due to asbestos, and chronic obstructive pulmonary diseases due to black coal dust were included in the last two updates of the Czech List. The need of an early examination at the Centers of Occupational Diseases is stressed in this article, especially before a surgery or other treatment of epicondylitis and carpal tunnel syndrome.

Cross sectional imaging of pulmonary fibrosis translating pathology into radiology.

Clin Imaging 2018 Sep - Oct;51:332-336. Epub 2018 Jun 27.

Department of Laboratory Medicine and Pathology, Mayo Clinic, Scottsdale, AZ, United States of America.

There are three major pathologic patterns of pulmonary fibrosis; usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP) and airway-centered fibrosis (ACF). These pathologic patterns correspond with radiographic patterns of UIP, NSIP, and chronic hypersensitivity pneumonitis (CHP). Previous studies have demonstrated that the radiologic diagnosis is correct approximately 50% of the time for these fibrotic lung diseases. Read More

Functional associations of pleuroparenchymal fibroelastosis and emphysema with hypersensitivity pneumonitis.

Respir Med 2018 05 30;138:95-101. Epub 2018 Mar 30.

Interstitial Lung Disease Unit, Royal Brompton Hospital, Royal Brompton and Harefield NHS Foundation Trust, London, UK.

Background: Pleuroparenchymal fibroelastosis (PPFE) has been described in hypersensitivity pneumonitis (HP) yet its functional implications are unclear. Combined pulmonary fibrosis and emphysema (CPFE) has occasionally been described in never-smokers with HP, but epidemiological data regarding its prevalence is sparse. CTs in a large HP cohort were therefore examined to identify the prevalence and effects of PPFE and emphysema. Read More

Detection of some new Trichosporon species from the dystrophied nails of three female members of a family from North Indian State of Jammu and Kashmir.

Mycoses 2018 Aug 6;61(8):534-542. Epub 2018 Apr 6.

School of Biotechnology, University of Jammu, Jammu, India.

Dermatophytes are considered as the main pathogens responsible for onychomycosis, but recently successive isolations of yeast-like fungi from the infected nails has led to consider these also as primary agents of nail infections. Trichosporon species which are non-candidal, basidiomycetous, yeast-like, anamorphic fungi are commonly isolated from soil but they are also emerging as important etiological agents of onychomycosis. Three species of Trichosporon viz. Read More

Evaluation of Nickel Release from Endobronchial Valves as a Possible Cause of Hypersensitivity Pneumonitis in a Patient Treated with Bronchoscopic Lung Volume Reduction.

Int Arch Allergy Immunol 2017 15;174(3-4):144-150. Epub 2017 Nov 15.

Department of Pulmonology, University Hospital Zurich, Zurich, Switzerland.

Background: Endobronchial valve (EBV) placement is an established lung volume reduction procedure aiming to improve lung function and exercise capacity in patients with severe emphysema. As EBVs consist of silicone and nitinol (a metal alloy of nickel and titanium), there are concerns that nickel ions might be released and could have a clinical impact in patients with a contact allergy to nickel. Based on a case with hypersensitivity pneumonitis (HP) after treatment with EBVs, we aimed to evaluate the in vitro nickel release from EBVs using inductively coupled plasma mass spectrometry (ICP-MS) and scanning electron microscopy (SEM).

a Pulmonary Division, Instituto do Coracao (InCor), Hospital das Clinicas HCFMUSP, Faculdade de Medicina , Universidade de Sao Paulo , Sao Paulo , Brazil.

Introduction: Hypersensitivity pneumonitis (HP) is a disease with variable clinical presentation in which inflammation in the lung parenchyma is caused by the inhalation of specific organic antigens or low molecular weight substances in genetically susceptible individuals. Alterations of the acute, subacute and chronic forms may eventually overlap, and the diagnosis based on temporality and presence of fibrosis (acute/inflammatory HP vs. chronic HP) seems to be more feasible and useful in clinical practice.

Usefulness of à la carte antigens for bird fancier's lung serodiagnosis: total dropping extract and/or dropping's microflora antigens.

J Med Microbiol 2017 Oct 13;66(10):1467-1470. Epub 2017 Sep 13.

1​UMR 6249 Chrono-Environment, University of Bourgogne-Franche-Comté, Besançon, France.

Bird fancier's lung (BFL) is a pulmonary disease caused by inhalation of avian proteins. The involvement of the microorganisms of droppings has been assumed in the past and this idea still persists today. Our study aimed to compare by immunoprecipitation assay the detection of antibodies against both droppings and microorganisms in the sera of patients (n=15) and asymptomatic exposed controls (n=18).

Exploring efficacy and safety of oral Pirfenidone for progressive, non-IPF lung fibrosis (RELIEF) - a randomized, double-blind, placebo-controlled, parallel group, multi-center, phase II trial.

BMC Pulm Med 2017 Sep 6;17(1):122. Epub 2017 Sep 6.

Department of Internal Medicine II, University of Giessen-Marburg Lung Center, Justus-Liebig University Giessen, Giessen, Germany.

Background: Pirfenidone is currently approved in the EU for the treatment of mild to moderate idiopathic pulmonary fibrosis (IPF) and offers a beneficial risk-benefit profile. However, there are several other, progressive fibrotic lung diseases, in which conventional anti-inflammatory therapy is not sufficiently effective and antifibrotic therapies may offer a novel treatment option.

Methods/design: We designed a study protocol for inclusion of patients with progressive fibrotic lung disease despite conventional anti-inflammatory therapy (EudraCT 2014-000861-32). Read More

Metal worker's lung: spatial association with .

Thorax 2018 02 29;73(2):151-156. Epub 2017 Aug 29.

Royal Brompton and Harefield NHS Foundation Trust, London, UK.

Background: Outbreaks of hypersensitivity pneumonitis (HP) are not uncommon in workplaces where metal working fluid (MWF) is used to facilitate metal turning. Inhalation of microbe-contaminated MWF has been assumed to be the cause, but previous investigations have failed to establish a spatial relationship between a contaminated source and an outbreak.

Objectives: After an outbreak of five cases of HP in a UK factory, we carried out blinded, molecular-based microbiological investigation of MWF samples in order to identify potential links between specific microbial taxa and machines in the outbreak zone. Read More

This article is an abridged version of the AWMF mould guideline "Medical clinical diagnostics of indoor mould exposure" presented in April 2016 by the German Society of Hygiene, Environmental Medicine and Preventive Medicine (), in collaboration with the above-mentioned scientific medical societies, German and Austrian societies, medical associations and experts. Indoor mould growth is a potential health risk, even if a quantitative and/or causal relationship between the occurrence of individual mould species and health problems has yet to be established. Apart from allergic bronchopulmonary aspergillosis (ABPA) and mould-caused mycoses, only sufficient evidence for an association between moisture/mould damage and the following health effects has been established: allergic respiratory disease, asthma (manifestation, progression and exacerbation), allergic rhinitis, hypersensitivity pneumonitis (extrinsic allergic alveolitis), and increased likelihood of respiratory infections/bronchitis.

An immunoproteomic approach revealed antigenic proteins enhancing serodiagnosis performance of bird fancier's lung.

J Immunol Methods 2017 11 29;450:58-65. Epub 2017 Jul 29.

UMR/CNRS 6249 Chrono-Environnement, University of Bourgogne Franche-Comté, UFR Sciences médicales et pharmaceutiques, 19 rue Ambroise Paré, 25030 Besançon, France; Biomedical Department, University Hospital, 2Bd Fleming, 25030 Besançon, France.

Background: Bird fancier's lung (BFL) caused by repeated inhalation of avian proteins is the most common form of hypersensitivity pneumonitis. However, the exact identification of proteins involved is unknown, and serological test use for diagnosis need to be standardized. The objectives of this study were (i) to identify antigenic proteins from pigeon droppings (ii) to provide information about their location in avian matrices and (iii) to produce them in recombinant proteins to evaluate their diagnostic performances.

Small airway dysfunction in chronic hypersensitivity pneumonitis.

Respirology 2017 11 26;22(8):1637-1642. Epub 2017 Jul 26.

Department of Respiratory Physiology, National Institute of Respiratory Diseases, Mexico City, Mexico.

Background And Objective: Lung biopsies from patients with hypersensitivity pneumonitis (HP) have demonstrated small airway (SA) involvement, but there is no information concerning SA function in HP, and it is unknown whether pharmacological treatment could modify its function. SA function in patients with chronic HP using ultrasonic pneumography (UPG) and impulse oscillometry (IOS) was explored. We also compared initial results with those obtained after 4 weeks of standardized treatment with azathioprine and prednisone. Read More

Diagnostic implications of positive avian serology in suspected hypersensitivity pneumonitis.

Respir Med 2017 08 27;129:173-178. Epub 2017 Jun 27.

Division of Pulmonary and Critical Care Medicine, Mayo Clinic, Rochester, United States. Electronic address:

Background: The diagnostic evaluation of patients with interstitial lung disease (ILD) often involves serologic assessment for identifiable causes such as hypersensitivity pneumonitis (HP). While not on its own defining of HP, precipitin serologies are often obtained to support clinical suspicion if other findings are inconclusive. We studied the clinical relevance of positive avian serology in patients undergoing ILD evaluation. Read More

Rom J Morphol Embryol 2017 ;58(2):627-634

Department of Mother and Child, Faculty of Medicine, "Iuliu Hatieganu" University of Medicine and Pharmacy, Cluj-Napoca, Romania;

Hypersensitivity pneumonitis (HP; extrinsic allergic alveolitis) is a rare non-immunoglobulin E (IgE)-mediated inflammatory lung disease caused by inhalation exposure (occupational, recreational or ordinary home exposure). A 36-year-old female patient, without significant medical history, is referred to an outpatient pulmonology clinic for dry cough, shortness of breath, fever, fatigue and weight loss. Chest high-resolution computed tomography (HRCT) was performed, and significant lung fibrosis (especially centrilobular and interlobular in bilateral "thick lines"), traction bronchiectasis and alveolitis in both superior lobes are described.
