Rheumatoid pneumoconiosis: a study in colliery populations in the East Midlands coalfield.

Influence of rheumatoid factor in coalminers' pneumoconiosis in the Fujian Shaowu colliery, south China.

Coalminers' pneumoconiosis may be complicated by the development of progressive massive fibrosis (PMF) or by rheumatoid pneumoconiosis (Caplan's syndrome).'2 The arthritis in Caplan's syndrome may precede, coincide with, or follow the development of pulmonary radiological shadows. These conditions are common in miners and may be seen in workmen exposed to dusts other than coal.' The Fujian Shao...

Pneumoconiosis of coal miners in north east England with special reference to the Durham coalfield.

Genetic analysis of CRHRA1 and CRHRA2 microsatellites and their association with rheumatoid arthritis in South Asian and Caucasian populations of the East Midlands, UK

Two microsatellites from corticotropin releasing hormone (CRH) gene locus (CRHRA1 and CRHRA2) were reported to be associated with rheumatoid arthritis (RA) in Caucasians. This study aims to replicate the association in a South Asian (SA) and Caucasian RA sample from the East Midlands, UK. DNA from 281 South Asians (111 patients, 43 siblings, 127 controls) and 287 Caucasians (116 patients, 64 si...

Comparison of the Cumulative Incidence Rates of Coal Workers’ Pneumoconiosis between 1970 and 2013 among Four State-Owned Colliery Groups in China

The purpose of this study was to identify differences in the incidence characteristics of coal workers' pneumoconiosis (CWP) based on data from four large state-owned colliery groups of China, by comparing the cumulative incidence rates of CWP. We investigated 87,904 coal workers from the Datong, Kailuan, Fuxin, and Tiefa Colliery Groups, who were exposed to dust for at least 1 year. The cumula...

A study of the reproducibility of the forced vital capacity of coalworkers at two collieries in Scotland and two collieries in South Wales.

A study of 1,522 coalworkers at two Scottish collieries and two Welsh collieries showed that the forced vital capacity (F.V.C.) was as reproducible a measurement as the forced expiratory volume (F.E.V.) (1 sec.). This applied not only to replicate readings, but also between readings taken before and after a working shift on the same day, and also between readings taken at an interval of one wee...
