Silicosis among Cape gemstone workers : tigers' eye pneumoconiosis
Silicosis continues to be an important occupational disease in South Africa, particularly in small, poorly regulated industries. A case series is described of six workers who developed silicosis whilst involved in the processing of semi-precious gem stones. They had been employed as stone sculptors …

Silicosis pulmonary dysfunction and respiratory symptoms in South African gold miners
… of this study is to examine the influence of silicosis and the occupation of gold mining on respiratory symptoms, lung function and tuberculosis in a working population of black, migrant, South African gold miners. No previous study has examined a working population of these men.

Variation in silicosis prevalence in South African gold miners : an industry-wide study
This study investigates the prevalence of silicosis in the South African gold mining industry. Gold mining is an important industry in South Africa, yet has been blighted by silicosis and tuberculosis in miners since its inception in 1887. There have been two previous studies conducted in black …

Experiencias y vivencias de marmolistas diagnosticados de silicosis tras el mecanizado de aglomerados artificiales de cuarzo
Introducción: La silicosis resurge en nuestro país con el mecanizado de los AAC. En Chiclana de la Frontera (Cádiz), se detecta la mayor concentración de marmolistas afectados de silicosis por AAC conocida en España, y probablemente en Europa. Sin embargo, nuevos casos están apareciendo dentro y …

Illuminating a neglected population: epidemiological and clinical features of silicosis and tuberculosis among former gold miners from Lesotho
Background Silicosis, tuberculosis (TB), and human immunodeficiency virus (HIV) infection, singularly and together, are all global health concerns. Southern Africa, with its high HIV and TB prevalence and incidence, is the most affected region by these conditions. The large South African mining …

The best of times, the worst of times: A bio-cultural analysis of the Ferguson District, 1892-1909
… variables investigated. The hypothesis that silicosis ("miner's consumption") was the leading cause of death in the District during this period is tested. Mortality and morbidity rates in the study area are compared with similar data from two other Nevada mining regions; The results of the …

Unearthing the relationship between disease and causation in South African gold mines
… failure to protect mineworkers from exposure to silicosis, silico-tuberculosis and pulmonary tuberculosis. It is argued that the Constitutional Court's interpretation, and their ultimate application of the test for factual causation in Lee v Correctional Services 2013 (2) SA 144 (CC), in the form …
