A 49-year-old man who had been working in the sanding and deburring department of a factory producing underground water pipes for 15 years, presented with complaints of effort dyspnea, cough and loss of strength in his left hand. Computed tomography of the lung revealed diffuse micronodular appearance in all zones in both lungs, subpleural nodule and bronchial dilatation...

Hospital noise has remained a low priority problem in India. An area of not less than 100 meters around a hospital is considered a silence zone, with guidelines restricting noise levels at 50dBA during daytime and 40dBA during the night. World Health Organization (WHO) guidelines also stipulate an average of 30dBA and a maximum of 40dbA. Annoyance is a known effect of noise exposure. However, very few studies have attempted to explore the hospital soundscape and the annoyance among staff related to it. Noise data was collected from 30 sites, using a Digital Integrating Sound Level Meter, LutronSL-4035SD (ISO-9001,CE,IEC1010) meeting IEC61672 standards...

This study aims to explore the barriers that prevent the implementation of occupational health and safety regulations in Lebanon. A qualitative approach was adopted including a document analysis of the available legal documents pertaining to occupational health and safety at the national level and ten in-depth interviews with professionals in the field of occupational health and safety in Lebanon. Our findings show that the implementation of the occupational health and safety regulations in Lebanon is hindered by several barriers including the lack of a holistic legal framework, lack of promotion of a health and safety culture at work, insufficient number of labor inspectors, insufficient training for labor inspectors, lack of necessary tools and equipment, lack of an adequate documentation system, hierarchy within the Ministry of Labor, weak compliance, and the influence of the informal sector...

Rising temperatures and heat events may affect workers, especially women, by increasing the risk of Heat Related Illnesses (HRIs). We conducted a cross-sectional study among 903 women in outdoor and indoor sectors. We measured Wet Bulb Globe Temperature (WBGT) and physiological Heat Strain Indicators (HSI), as well as self-reported symptoms of HRIs using a HOTHAPS questionnaire. Multivariate Logistic Regression models were used to compare the heat risks. WBGT exposures were high in both the outdoor (Avg. WBGT = 28...

Hypersensitivity pneumonitis (HP), also known as extrinsic allergic alveolitis, is the most common interstitial lung disease in children, but remains rarely recognized in the pediatric population. Early recognition of triggering factors and a high index of suspicion of HP could lead to timely diagnosis and individualized treatment. This study aimed to present four clinical cases of HP reported between 2012 and 2022 in Lithuania to improve the suspicion of the disease in children.

This study assessed perceptions of German physicians' regarding the impact of the COVID-19 pandemic on work-related issues as well as mental and physical health.
