A 61-year-old man was evaluated for a 2 month history of cough and dyspnea without relevant exposures other than pyrethrin containing insecticidal sprays he used while grooming dogs almost daily. High Resolution Computed Tomography (HRCT) of the chest demonstrated a Non-Specific Interstitial Pneumonia (NSIP) pattern. Pulmonary function testing revealed an isolated mildly reduced diffusion capacity. Bronchoalveolar lavage (BAL) results confirmed the presence of foamy histiocytes, lymphocytes, and polymorphonuclear cells consistent with ongoing exposure...

Electrical impedance tomography (EIT) has undergone 30 years of development. Functional chest examinations with this technology are considered clinically relevant, especially for monitoring regional lung ventilation in mechanically ventilated patients and for regional pulmonary function testing in patients with chronic lung diseases. As EIT becomes an established medical technology, it requires consensus examination, nomenclature, data analysis and interpretation schemes. Such consensus is needed to compare, understand and reproduce study findings from and among different research groups, to enable large clinical trials and, ultimately, routine clinical use...

[Purpose] This cross-sectional study aimed to compare foundry workers of the metallurgical industry with high and low exposure time and with a control group. [Subject and Methods] The workers were evaluated for pulmonary function and peak expiratory flow (PEF), respiratory symptoms, smoking habits, and physical activity level. Descriptive statistical analysis and ANOVA one-way test were used. [Results] The mean age was 33.9 ± 8.25 years (18-59), pulmonary function: FVC: 95 ± 18% of predicted, FEV1: 95.0 ± 15...

BACKGROUND: An inverse association between socioeconomic status and pulmonary function has emerged in many studies. However, the mediating factors in this relationship are poorly understood, and might be expected to differ between countries. We sought to investigate the relationship between socioeconomic status and lung function in China, a rapidly industrializing nation with unique environmental challenges, and to identify potentially-modifiable environmental mediators. METHODS: We used data from the Shanghai Putuo Study, a cross-sectional study performed in Shanghai, China...

Pseudomonas species are opportunistically pathogenic to humans, yet closely related species are used in biotechnology applications. In order to screen for the pathogenic potential of strains considered for biotechnology applications, several Pseudomonas strains (P.aeruginosa (Pa), P.fluorescens (Pf), P.putida (Pp), P.stutzeri (Ps)) were compared using functional virulence and toxicity assays. Most Pa strains and Ps grew at temperatures between 28°C and 42°C. However, Pf and Pp strains were the most antibiotic resistant, with ciprofloxacin and colistin being the most effective of those tested...

BACKGROUND: Galvanization is the process of coating steel or cast iron pieces with a thin layer of zinc allowing protection against corrosion. One of the important hazards in this industry is exposure to zinc compounds specially zinc oxide fumes and dusts. In this study, we evaluated chronic effects of zinc oxide on the respiratory tract of galvanizers. METHODS: Overall, 188 workers were selected from Arak galvanization plant in 2012, 71 galvanizers as exposed group and 117 workers from other departments of plants as control group...

INTRODUCTION: Congestive heart failure (CHF) is a common disease and its prevalence is increasing in industrialized countries. NT-proBNP measurement is an established diagnostic test for diagnosis of CHF in patients who present to emergency room with acute dyspnea. The primary object of this study was to determine the relationship between levels of brain natriuretic peptide precursor and severity of lung function impairment in patients with chronic CHF. METHODS: This cross-sectional and analytical study that performed in Tuberculosis and Lung Disease Research Center of Tabriz University of Medical Sciences on 95 patients with chronic heart failure, and relation between NT-proBNP levels and pulmonary function parameters were examined...

BACKGROUND: Known respiratory health effects of exposure to cotton dust are mainly altered pulmonary function findings and symptom of chest tightness. A number of studies have been carried out all over the world to enumerate and evaluate the health effects of cotton dust exposed workers in different processes. However, such studies carried out in ginning industry especially in Indian context are scanty. OBJECTIVES: This study was initiated to explore occupational and morbidity details and respiratory functional status of the exposed workers as well as to investigate across the working shift pulmonary function changes...

There is an increase in proportion of workers suffering from occupational diseases. In occupational respiratory diseases, pulmonary function tests are the most important and widely used diagnostic tool. Limited studies have been conducted to evaluate the effect of wool dust on pulmonary function parameters. Hence, the present study was undertaken to evaluate the pulmonary function parameters in workers of woolen industry. This study was done on 150 subjects of either gender who were divided into two groups of 75 each...

Up to now the exposures to hair and skin derivatives of animals have not yet been the subject of systematic studies. The observation of a clinical case has provided the opportunity for a review of the literature. The inpatient was a 49-year-old man, a carder in a textile factory, exposed to angora wool. He noticed the appearance of dyspnea during working hours. There was no eosinophilia in blood, and the results of pulmonary function tests were normal. The nonspecific bronchial provocation test with methacholine demonstrated an abnormal bronchial reactivity...

Emergency responders may be exposed to a variety of fumes, gases, and particulates during the course of their job that can affect pulmonary function (PF) and require the use of respiratory protection. This investigation used occupational health monitoring examination data to characterize PF in a population currently employed as emergency responders. PF tests for workers who required health examinations to ensure fitness for continued respirator use were compared to the National Health and Nutrition Examination Survey (NHANES) III Raw Spirometry database to determine if decreased PF was associated with employment as an emergency responder...

Evidence-based medicine is advocated by WHO and adopted by developed countries for many years. In China, however, the selection of essential medicine and various medical insurance reimbursement schemes medicine is usually based on experts' experience of prescription practice which is under heavy critics resulting from the lack of related comparative efficacy and evidence-based research. The efficacy of Jian'ganle in prevention of drug-induced liver injury (DILI) caused by antituberculotics was evaluated in this study by comparison with Hugan Pian, glucuronolactone and reduced glutathione...
