Background Occupational allergic diseases are a major problem in some workplaces like in the baking industry. Diagnostic rules have been used in surveillance but not yet in the occupational respiratory clinic. Objective To develop diagnostic models predicting baker’s asthma and rhinitis among bakery workers at high risk of sensitisation to bakery allergens referred to a specialised clinic. Methods As part of a medical surveillance programme, clinical evaluation was performed on 436 referred Dutc...

Background: A diagnostic model predicting sensitization to wheat flour allergens in bakers has been implemented in a nationwide medical surveillance program using a short self-administered questionnaire. This model allows risk stratification of bakers at risk to select for clinical evaluation. Objective: To explore the added value of a medical history taken by a physician, and to study whether it is possible to predict occupational asthma and allergy. Methods: Data were derived from an ongoing m...

Background: In population studies, automated portable devices are used to measure lung function on location. A build-in automated quality algorithm selects technically correct lung function data for analysis. Aim: To evaluate the performance of intergraded quality control in lung function testing equipment. Methods: Lung function measurements in 6137 children (age 6 -13) were collected from the HITEA, FRESH and the PIAMA study. All measurements were performed with a portable device, which uses a...

Introduction: Inadequate breathing manoeuvres during inspiratory and expiratory High Resolution Computed Tomography (HRCT) may conceal differences in lung density. Although spirometer-controlled HRCT is advocated, this technique is not common practice. The aim of this study was to determine breathing levels during inspiration and expiration HRCT as achieved after standard breathing instructions by the radiology assistant. Methods: during HRCT Inspiratory Capacity (IC insp,CT ) and Expiratory Res...

Silica dust-exposed individuals are at high risk of developing silicosis, a fatal and incurable lung disease. The presence of disseminated micronodules on thoracic CT is the radiological hallmark of silicosis but locating micronodules, to identify subjects at risk, is tedious for human observers. We present a computer-aided detection scheme to automatically find micronodules and quantify micronodule load. The system used lung segmentation, template matching, and a supervised classification schem...

Pre-employment examination is considered to be an important practice and is commonly performed in several countries within the European Union. The benefits of medical surveillance programmes are not generally accepted and their structure is often inconsistent. The aim of this review was to evaluate, on the basis of the available literature, the usefulness of medical screening and surveillance. MEDLINE was searched from its inception up to March 2010. Retrieved literature was evaluated in a peer-...

To determine the prevalence of increased micronodule counts in silica dust–exposed smokers. We evaluated 54 male smokers with severe silica dust exposure and 54 male control smokers. Both groups underwent low-dose chest computed tomography and lung function testing. Computed tomographic scans were visually evaluated for solid micronodules (<3 mm). The 95th percentile of micronodule count was calculated for the control smokers. Prevalence of an increased micronodule count was assessed for the dus...

Work-related asthma, which includes occupational asthma and work-aggravated asthma, has become one of the most prevalent occupational lung diseases. These guidelines aim to upgrade occupational health standards, contribute importantly to transnational legal harmonisation and reduce the high socio-economic burden caused by this disorder. A systematic literature search related to five key questions was performed: diagnostics; risk factors; outcome of management options; medical screening and surve...

Objectives To investigate exposures, respiratory symptoms, lung function and exposure–response relationships among aluminium cast-house workers. Methods A cross-sectional study was conducted among 182 workers. Exposure data were used to model exposure to irritants. Lung function and questionnaire data on respiratory symptoms were compared to a general population sample and an internal reference group. Blood samples were taken from 156 workers to examine total IgE, eosinophils and sensitisation t...
