talc 2 assessment

WebSafety Assessment of Talc as Used in Cosmetics . No epidemiological studies were identified that assessed consumer use of talc and talcum powder products. The TROG-2 is suitable for use by Speech and Language Therapists, Psychologists and Teachers of the Deaf. In mice, intra-alveolar macrophages were focally aggregated. Ierardi and Marsh (58) conducted a power analysis to determine whether the pooled cohorts could detect a true association between talc exposure and mesothelioma risk among talc miners and millers, if there were one. Using detailed employment histories and a job exposure matrix, cumulative talc exposures were estimated, and each cohort member was assigned a concentration of low (2.5 mg/m3), medium (10 mg/m3), or high (40 mg/m3). Histologic evaluation of lung tissue revealed no exposure-related lesions except for a modest, diffuse increase in free macrophages within alveolar spaces of both rats and mice exposed to the highest concentration of talc. The increased risk among those hired before 1955 was strongest among miners (SMR = 3.94; 95% CI: 2.336.22, based on 18 cases) and not elevated among millers (SMR = 1.28; 95% CI: 0.512.63, based on 7 cases). 45. how do you think he feels? Children can have a literal understanding and a specific view point. Webbreathing in loose talc powder may cause lung effects, such as coughing, trouble breathing, decreased lung function and fibrosis; and. Particle overload is common when high doses of poorly insoluble particles are administered particle clearance mechanisms of the lung are overwhelmed and carcinogenic processes are initiated (23, 24): see Mechanistic evidence and Mode of Action. There was no evidence of carcinogenicity in mice exposed to talc. If you would like any more information on any of the services we offer or would like to book an appointment, do not hesitate to contact us and one of our team will be happy to help. The relevance of the rat lung response to particle overload for human risk assessment: a workshop consensus report. The mortality experience of upstate New York talc workers. For animal toxicology and selected mechanistic studies, we followed the TSCA study quality evaluation framework (12, 13) and assigned relative numerical ranks to each of the outcomes (1, 2, and 3 corresponding to high, medium, and low) for each metric, then averaged the metric scores to arrive at an overall relative rating of high, medium, or low quality. what should we do now? International Journal of Pharmaceutical Sciences Review and Research, Cosmetics are the products that are used to apply to our skin, face and hair every day and its uses are increasing around the world. In an in vivo OECD Guideline 478 Dominant lethal test, male Sprague-Dawley rats were exposed via gavage to a single dose or one dose/day for 5 days of 300, 3,000, or 5,000 mg/kg talc.

Stille WT, Tabershaw IR.

Methods for collecting and analysing respirable talc generated during the use of loose face powder and adult and baby dusting powders were established. Ierardi AM, Marsh GM. 0000002271 00000 n The sample was stratified by age, gender, geographical distribution and SES using the 2001 census statistics. (2002) 59:98105. Generally, lung talc burdens of mice exposed to 18 mg/m3 were disproportionately greater than those of mice exposed to 6 mg/m3, suggesting clearance of talc from the lung was impaired in mice exposed to 18 mg/m3. The normalized lung talc burdens for both mice and rats were lower at the lowest exposure level than at the two higher exposure levels; however, the difference was statistically significant only for the rats. office@sltforkids.co.uk Inhal Tox.

We provide specialist speech and language therapy services for children with voice difficulties. In: Health Health Related Effects of Phyllosilicates Bignon J, , editors. Shim I, Kim HM, Yang S, Choi M, Seo GB, Lee BW, et al. Although the paucity of mechanistic information remains a limitation, the balance of evidence, especially the volume of epidemiological evidence demonstrating no increased cancer risks associated with even the highest real world human-relevant exposures, strengthens the current analysis. None of the 17 cohort studies identified an increased risk of malignant pleural or peritoneal mesothelioma among talc miners and millers. As a powder, it absorbs moisture well and helps cut down on friction, making it useful for keeping skin dry and helping prevent rashes. 0000070271 00000 n J Occup Env Med. The Cosmetic Ingredient Review Expert Panel (Panel) assessed the safety of talc for use in cosmetics. Integrating the evidence demonstrating a lack of statistically significant increases in mesothelioma in inhalation rodent bioassays, the null findings in the higher-quality epidemiological literature, and the lack of evidence of a plausible MOA, we conclude that there is suggestive evidence of no association between inhaled talc and mesothelioma at human-relevant exposure levels. Eur Resp J. 0000018595 00000 n A brief overview of the quality evaluation results is presented below, followed by a summary of study findings. For pulmonary cancers, it is therefore plausible that talc could cause irritation and a cascade of inflammatory mechanisms. Categorizations for evaluating strength of evidencea (8).

While this does not affect the quality of the study, as discussed below, micronized talc is not used in cosmetic talcum powder products and may limit the study's generalizability for assessing risk associated with the use of cosmetic talcum powder.

Among 705 white men employed between 1957 and 1977, lung cancer mortality was statistically significantly elevated among workers employed < 1 year (SMR = 3.17, based on six lung cancer deaths). 0000070520 00000 n Feb., 1980.

Overall conclusions were derived for each cancer: sufficient evidence of a causal relationship; sufficient evidence, suggestive evidence, or inadequate/insufficient evidence of an association; or suggestive evidence of no association. Talc is a naturally occurring mineral. A nested case control study of lung cancer among New York talc workers. The pulmonary toxicity of talc and granite dust as estimated from an in vivo hamster bioassay. It has been reported that some cosmetic talcs and finished talcum powders may contain trace levels of asbestiform minerals despite the lack of evidence of reliably detectable asbestos at the major sources (1). The Test of Abstract Language Comprehension can be used by speech and language therapists to assess your childs understanding of concrete and abstract language through different style questions. A few studies reported excess lung cancer mortality, but lung cancer mortality risk did not increase with increasing talc exposure and the association potentially was confounded by smoking. The tiering system allows for preferentially weighting specific quality domains (e.g., exposure characterization) first, followed by more secondary determinants of study quality. Overall, the mechanistic evidence is insufficient to support an MOA whereby talc induces pulmonary carcinogenesis. 122. Briefly, the cohorts ranged in size from about 400 (53) to over 1,700 (1) miners and millers that were followed for mortality for up to seven decades. The original standardised version included norms of over 2,000 children and was published in 1983 with slight modifications made in 1989. As with other particles, one postulated carcinogenic MOA for talc is chronic inflammation resulting from the overwhelming of particle clearance mechanisms (i.e., phagocytosis), long-term tissue irritation and release of inflammatory chemokines and cytokines, and reactive oxygen species (ROS) formation. The estimated average SMR for lung cancer was 1.45 (95% CI: 1.221.72, ) among the workers exposed to talc.Figure 2 shows the forest plot corresponding to the summary lung cancer SMR calculated in the meta-analysis.

Although one meta-analysis (5) reported a statistically significant meta-SMR of 1.45 (95% CI: 1.221.72) for non-asbestiform talc and lung cancer, this review included several occupational cohorts with mixed exposures to possible lung carcinogens such as silica, asbestos, and radon (miners) resulting in high heterogeneity across reported study results.
