“…The prevalence of silicosis is increased in developing countries, including Brazil, China, India and Vietnam. In India, the prevalence is increased in, for instance, workers in Kolar Gold Fields, Karnataka, and there is a high risk of silicosis in the slate pencil and agate grinding industry 3. Our patient had a total of 11 years of exposure to silica dust while working in a glass factory and later in a talc powder company.…”

Burst abdomen: an unusual complication of silicosis in pregnancy

We present a case of silicosis in a 37-year-old pregnant woman, a second gravida with previous caesarean section. She was referred to our hospital at 42 weeks of gestation with breathlessness and oligohydramnios. She had worked in a glass and talc powder factory for 11 years and was diagnosed as having silicosis 2 years prior; she was on treatment. Following admission, she was evaluated for dyspnoea and underwent emergency Caesarean section for poor cervical dilation. She developed a burst abdomen on the third postoperative day with loops of gangrenous bowel protruding outside the abdomen. Emergency laparotomy with ileal resection and ileostomy was carried out. She was discharged on day 14 and is on follow-up. To the best of our knowledge, this is the first case of silicosis in pregnancy presenting with an unusual complication.

“…Some farming, construction and demolition activities also contribute to the environmental exposure. Relation between occupational exposure and prevalence of silicosis and silico-tuberculosis has been established beyond doubt in many occupations (Hnizdo and Sluis-Cremer 1993;Saiyed et al 1985;Jiang et al 2001;Sadhu et al 1995). But there have been very few studies, which suggest that there can be non-occupational silicosis also.…”

“…The subsequent operations of collecting, sorting and packing are carried out manually near the cutting machine. Saiyed et al (1985) reported that total and respirable dust levels near cutting machine were 46.47 and 10.41 mg/m 3 respectively. Medical survey revealed that prevalence of silicosis in this industry was 54.6%.…”

Non-occupational exposure to crystalline silica (quartz) in vicinity of slate pencil industry is reported. Ambient silica monitoring was carried out at two locations in the vicinity of slate pencil industry and one control site 5 kilometers away from slate pencil industry using PM-10 high volume samplers. Quartz content was analyzed using Fourier Transform Infrared Spectrophotometer (FTIR) from vertically elutriated dust samples collected simultaneously at all locations. It was found that average quartz concentrations in the vicinity of slate pencil industry and control site were 41.07-57.22 and 3.51 microg/m(3), respectively. Results were compared with derived ambient air quality standard for silica based on findings reported by Environmental Protection Agency (EPA).

India being a developing nation is faced with traditional public health problems like communicable diseases, malnutrition, poor environmental sanitation and inadequate medical care. However, globalization and rapid industrial growth in the last few years has resulted in emergence of occupational health related issues. Agriculture (cultivators i.e. land owners+ agriculture labourers) is the main occupation in India giving employment to about 58% of the people. The major occupational diseases/morbidity of concern in India are silicosis, musculo-skeletal injuries, coal workers' pneumoconiosis, chronic obstructive lung diseases, asbestosis, byssinosis, pesticide poisoning and noise induced hearing loss. There are many agencies like National Institute of Occupational Health, Industrial Toxicology Research Centre, Central Labour Institute, etc. are working on researchable issues like Asbestos and asbestos related diseases, Pesticide poisoning, Silica related diseases other than silicosis and Musculoskeletal disorders. Still much more is to be done for improving the occupational health research. The measures such as creation of advanced research facilities, human resources development, creation of environmental and occupational health cells and development of database and information system should be taken.
