We relied most heavily on the U.S. Environmental Protection Agency's (EPA) protocol for systematic reviews conducted under the Toxic Substances Control Act (TSCA) and the Draft Handbook for the Integrated Risk Information System (IRIS) (7). Integrating all streams of evidence according to the IOM framework yielded classifications of suggestive evidence of no association between inhaled talc and lung cancer and pleural mesothelioma at human-relevant exposure levels. Each study was reviewed for relevance, and if the full text met inclusion criteria, study information was extracted into tables and the study was evaluated for reporting and methodological quality.

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). 38. Talc was negative for mutagenicity and other forms of genotoxicity in all available assays, described in brief below. (2014) 42:86376. 43. endstream endobj startxref (2017) 60:82130.

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. To comment on this thread you need to create a Mumsnet account. Two nested case-control studies were conducted in tandem with occupational mortality analyses (30, 31). 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. It is also useful for Neuropsychologists assessing adults with acquired language disorder. All three studies provided explicit descriptions of talc aerosolization with exposure consistently administered across both control and experimental groups (except for some fluctuations in the NTP study). Numerous validity studies, including studies of the tests sensitivity and specificity, are provided. Using a lower-tier assessment approach, a small margin of exposure (MOE) of 1.5 was obtained through the comparison of the NOAEC of 2 mg/m 3 to the average 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. Exposure to talc aerosol produced no statistically significant differences in body weight; survival; or the type, incidence, or degree of histopathological change, relative to unexposed controls. (2018) 92:25167. exposure to the perineal area from the use of certain products containing talc is a possible cause of ovarian cancer. Two adenomas (not considered cancerous) were observed in talc-exposed animals, 13 lung tumors were found in chrysotile-exposed animals, and one adenoma occurred in the air-exposed control group.

Two groups of 50 hamsters also were exposed to laboratory air as a control for 30 or 300 days.
