Human saliva offers a unique noninvasive approach for populational study. Purposes of this study were to investigate the feasibility of using saliva manganese (Mn) concentration as a biomarker of Mn exposure among career welders and to study the variations of Mn, copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) in saliva as affected by the welding profession. Forty-nine male welders, of whom...

The study related serum lead level to cardiopulmonary function, quality of life and musculoskeletal pain welders in Enugu, Nigeria. Snowball sampling technique was adopted reach over 100 Enugu resident welders. first who met the inclusion criteria gave their consent participate were sampled. welders’ 0.522µg/dl (0.06-1.26 µg/dl). had prevalent low back a very high for domain physical health wit...

OBJECTIVES The aim of this study was to evaluate the coexisting factors and usefulness of diagnostic methods in metal-induced asthma in Polish welders. MATERIALS AND METHODS Examination of 50 welders occupationally exposed to metals and with suspicion of metal-induced asthma (group A), 100 welders occupationally exposed to metals but without suspicion of metal-induced asthma (group B), and tw...

A new method for detecting DNA-protein cross-links involving selective precipitation of DNA containing cross-linked proteins by K(+)-sodium dodecyl sulfate was utilized in the peripheral WBC of 21 male metal arc welders and in 26 male controls of similar age and racial characteristics who were not exposed to welding fumes. DNA was quantitated by Hoechst fluorescence. Although the concentration ...

OBJECTIVES The welding process produces metal fumes and gases which may affect respiratory health. Technetium-99m diethylenetriaminepentaacetic acid (Tc-99m DTPA) dynamic lung scanning is an easy, noninvasive method to assess disorders of alveolar-capillary barrier permeability secondary to epithelial damage. We aimed to investigate the alveolar clearance by Tc-99m DTPA radioaerosol inhalation ...

BACKGROUND Metal Inert Gas (MIG) welding and Tungsten Inert Gas (TIG) welding are widely used for mild steel segments in basic metal industries. Pulmonary problems such as asthma, pulmonary inflammation, hyper-responsiveness of airways and higher susceptibility to infections are reported as the result of occupational exposure of welders to ozone and nitrogen oxides. Potent oxidizing agents like...

OBJECTIVE To describe the thin-section CT findings of arc-welders' pneumoconiosis. MATERIALS AND METHODS Eighty-five arc-welders with a three to 30 (mean, 15)- year history of exposure underwent thin-section CT scanning. The extent of abnormalities detected was correlated with the severity of dyspnea and pulmonary function tests. For comparison, images of 43 smoking males (mean 25 pack-year) ...

A new method for detecting DNA-protein cross-links involving selective precipitation of DNA containing cross-linked proteins by k -sodium dodecyl sulfate was utilized in the peripheral WBC of 21 male metal arc welders and in 26 male controls of similar age and racial characteristics who were not exposed to welding fumes. DNA was quantitated by Hoechst fluorescence. Although the concentration of...

BACKGROUND In 2011, the Department of Health in England recommended that welders should each receive a single dose of the 23-valent pneumococcal polysaccharide vaccine (PPV23). AIMS To assess the evidence behind the advice and its practical implications. METHODS The review was informed by a systematic search in Medline, which related pneumonia to welding and/or exposure to metal fume, and w...
