Platinum-salt sensation and occupational asthma in a non-platinum refinery worker

Authors: E Ratshikhopha, M Muvhali, T Singh, D Rees Source: Current Allergy & Clinical Immunology. March 2019 Vol 32, No 1 Summary: Introduction: Cases of sensitisation to platinum salts within platinum-processing sectors (particularly platinum refineries and motor-vehicle, catalytic-convertor production) have been extensively described. However, the occurrence of platinum salt sensitisation outside of these sectors is less well known. We present a case of platinum-salt sensitisation in a chemical plant worker cleaning reactors from platinum refineries. Methodology: A 32-year-old man working […]

Risk assessment of BTEX concentration from combustion of coal in a controlled laboratory environment

Authors: D Masekameni, R Moolla, M Gulumian and D Brouwer Source: International Journal of Environmental Research and Public Health 2018, 16, 95; doi:10.3390/ijerph16010095 Summary: Abstract: A D-grade type coal was burned under simulated domestic practices in a controlled laboratory set-up, in order to characterize emissions of volatile organic compounds (VOCs); viz. benzene, toluene, ethylbenzene and xylenes (BTEX). Near-field concentrations were collected in a shack-like structure constructed using corrugated iron, simulating a traditional house found in informal settlements in South Africa. […]

Subradiological silicosis

Authors: R Ehrlich, J Murray and D Rees Source: American Journal of Industrial Medicine 2018; 1-9 Summary: Abstract: The purpose of this commentary is to bring the neglected phenomenon of subradiological silicosis and its implications to the attention of readers. We define subradiological silicosis as silicosis detectable on pathological examination of lung tissue but not visible radiologically. For extent of the phenomenon, we draw on a study using a large South African autopsy database of deceased miners and chest radiographs […]

The significance of non-occupational asbestos exposure in women with mesothelioma

Authors: N Tlotleng, KS Wilson, N Naicker, CFN Koegelenberg, et al. Source: Respirology Case Reports 2019 Vol.7 Iss.1 e00386 Summary: Abstract: Malignant mesothelioma is a rare and aggressive pleural or peritoneal tumour almost always caused by exposure to asbestos fibres. Exposure to asbestos can cause malignant mesothelioma 30–40 years after exposure. A description of sources of exposure is important for prevention and possible financial compensation. Three women with cases of histologically confirmed malignant mesothelioma diagnosed from non-occupational asbestos exposure are […]
