The first two cases of asbestosis in Malaysia are reported. Both had considerable occupational exposure to asbestos dust in the past, with a long latency period exceeding 30 years. One case presented with distinctive clinical and radiological features, while the other case was only confirmed by histological diagnosis. The usefulness of modern investigation techniques such as CT scan in the diagnosis of asbestosis is also illustrated.
Information about asbestos issues at the national level was compiled for ten Asian countries (China, Indonesia, Japan, Korea, Malaysia, Philippines, Singapore, Taiwan, Thailand, and Vietnam) regarding 1) bans and consumption levels; 2) occupational exposure limits (OELs) and medical follow-up schemes; and 3) statistics and compensation status of asbestosis and mesothelioma victims. Only Singapore and recently Japan have adopted a total ban an asbestos. China, a major producer of chrysotile, showed an increasing consumption trend, which was typical of the less industrialized countries. Considerable differences between countries existed in OELs (0.1 to 5.0 fibers/mL) and medical follow-up of exposed workers. National statistics for asbestosis and mesothelioma were available for only the industrialized countries, where reported cases as well as compensated cases were relatively few. There is need to improve the quality and quantity of information, but the available information attests to unfavorable conditions in the less industrialized countries. Hence the experience of industrialized countries regarding asbestos and its use should be utilized to the fullest to improve the situation worldwide.
Occupational cancers, including mesothelioma and lung cancer are linked to the use of asbestos. Annually, at least 100,000 global deaths are attributed to asbestos exposure putting a heavy burden on national budgets. Expenses incurred on treatment of asbestos related diseases (ARDs) reduce households and national resource savings, while ARDs culminate in terminal burdens. The objective of this study is to measure the economic burden of ARDs and to assess the economic impact of asbestos consumption. The health and economic burden of asbestos was estimated in macro-global consumption-production model using production function frontier-based and generalized least squared approach for asbestos products and cost tabulation. Production, in metric tons (Mt) was adopted as a dependent variable among explanatory variables, including consumption. Information on treatment cost of asbestos related diseases (mesothelioma, asbestosis and lung cancer) was obtained from costing information and published literatures. Annual total economic burden of asbestos is at USD 11.92 billion. Out of this cost, USD 4.34 billion per annum is the economic burden of managing three common ARDs. The cost of compensation for patients suffering ARDs is USD 4.28 billion. From the remaining USD 3.3 billion, USD 2.93 billion is the value of asbestos consumed in 2003 and USD372.15 million is the loss of earning due to hospital visits and admissions. For every USD 1 spent on consumption of asbestos, global economy has to absorb almost USD 4 due to health consequences of ARDs. Banning of asbestos production and usage in production of goods has far-reaching impacts on household welfare, health and economic development. The insights revealed are expected to inform decision makers the need to ban all forms of asbestos, especially in developing countries where usage is increasing.
