Inorganic arsenic (iAs) is a carcinogen and could increase the risks of bladder, lung, and skin cancer. Mining and smelting of non-ferrous metals are common occupational arsenic exposures. In this study, 125 individuals working in non-ferrous metal smelting plants were separated into two groups according to urinary total arsenic (TAs) levels: group 1, TAs < 100 μg/g Cr; group 2, TAs ≥ 100 μg/g Cr. Demographic characteristics of participants were obtained by questionnaire interview. Levels of E-cadherin soluble ectodomain fragment (sEcad) and epidermal growth factor (EGF) in workers urine were determined by ELISA test...

INTRODUCTION: Appropriate identification of subjects who are candidates for spirometry through case-finding questionnaires may help solve the problem of chronic obstructive pulmonary disease misdiagnosis. The performance of case-finding questionnaires depends at least partially on the characteristics of the population used for their development. The use of an accurate threshold for the forced expiratory volume in 1 second / forced vital capacity ratio to define persistent airway obstruction is also vital in ascertaining chronic obstructive pulmonary disease...

Studies using advanced toxicological methods enabling in vitro conditions that are more realistic are currently needed for understanding the risks of pulmonary exposure to airborne nanoparticles. Owing to the carcinogenicity of certain nickel compounds, the increased production of nickel nanoparticles (Ni-NPs) raises occupational safety concerns. The aim of this study was to investigate the genotoxicity of airborne Ni-NPs using a recently developed air-liquid interface exposure system. The wild-type Chinese hamster lung fibroblast cell line (V79) was used and cytotoxicity, DNA damage and mutagenicity were studied by testing colony forming efficiency, alkaline DNA unwinding and HPRT mutation assays, respectively...

BACKGROUND: During hyperthermic intraperitoneal chemotherapy (HIPEC), caregivers are exposed by different routes to cytotoxic drugs. This review proposes an overview of the safety of HIPEC by assessing existing data on protection procedures, biological and non-biological samples. Based on these data, relevant good practices, eventual irrelevant overprotection procedures and missing data to implement adapted protections are highlighted. MATERIALS AND METHODS: Data were extracted from a systematic review of literature from 1980 till 2016: number and type of surgical procedure, healthcare professionals present, protective equipment, samples, pre-analytical method and analytical method...

OBJECTIVE: The National Institute for Occupation Safety and Health-administered Coal Workers' Health Surveillance Program (CWHSP) provides radiographic pneumoconiosis screening for US coal miners. Radiographs are classified by readers according to International Labour Office criteria. In addition to pneumoconiotic parenchymal and pleural lung abnormalities, readers document radiographic features of importance (other symbols). Other symbols are not meant to imply a diagnosis or interpretation but are relevant as they provide information beyond a pneumoconiosis classification for features related to dust exposure and other aetiologies...

The large and rapidly growing number of engineered nanomaterials (ENMs) presents a challenge to assessing the potential occupational health risks. An initial database of 25 rodent studies including 1929 animals across various experimental designs and material types was constructed to identify materials that are similar with respect to their potency in eliciting neutrophilic pulmonary inflammation, a response relevant to workers. Doses were normalized across rodent species, strain, and sex as the estimated deposited particle mass dose per gram of lung...

An orthopaedic surgeon with no history of lung disease developed cough and dyspnoea. The patient was diagnosed with asthma by spirometry and bronchial provocation test with methacholine. A clear correlation between symptoms and work was established meriting a referral to a centre for occupational health. The patient was diagnosed with work-related disease, which was recognized by the industrial injury board. The cause was methyl methacrylate, a known airway irritant, which is an important component of bone cement...

REVIEW
Matthias Griese
Pulmonary alveolar proteinosis is a broad group of rare diseases that are defined by the occupation of a lung's gas-exchange area by pulmonary surfactants that are not properly removed. The clinical and radiologic phenotypes among them are very similar. The age of manifestation plays a central role in the differential diagnosis of the almost 100 conditions and provides an efficient path to the correct diagnosis. The diagnostic approach is tailored to identify genetic or autoimmune causes, exposure to environmental agents, and associations with numerous other diseases...

BACKGROUND: Pre-employment medical examination (PEME) sought to evaluate the ability of workers to work without risk to their own or others' health and safety. This is important especially in a hospital environment where the patients may be at risk in case of employees harbouring infectious lung conditions or as a result of occupational exposure. Although not all healthcare workers are at risk or pose risk, they are expected to undergo chest X-ray (CXR) as part of PEME. AIMS: The aim of this study is to determine the number of prospective employees with abnormal findings on routine CXR, describe their characteristics and reassess the value of CXR in PEME...
