The authors reported issues with the consistency of administration of talc aerosol over some weeks in the middle of the study, likely resulting in increased talc exposure. Conclusion Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of talc. The Chemical Abstracts Service Registry Number (CAS RN In mice, intra-alveolar macrophages were focally aggregated. Kleinfeld M, Messite J, Kooyman O, Zaki MH. 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. doi: 10.1016/S0015-6264(77)80317-9.

Methods used to derive cause of death were poorly described, and included a variety of sources including death certificates, employment records, and hospital records, resulting in a low quality rating for that domain, and low overall quality rating (44, 45). 0000000016 00000 n Malignant mesothelioma following repeated exposures to cosmetic talc: a case series of 75 patients. J Occup Env Med. Based on the quality evaluation methods, domains and quality criteria (described above and detailed for all studies in Supplementary Tables 5, 6), most of the studies assessing pulmonary cancer risk among talc miners and millers were rated medium quality.

One peritoneal mesothelioma was reported in both studies (the same individual) and analyses including this case in the category of gastric cancers found no excess risk overall or by specific age categories (44, 45). TROG-2 - Test for reception of grammar can be used with children from age 4 and it measures the understanding of grammatical contrasts TALC - Test of abstract language comprehension assesses the level of abstract language a child understands doi: 10.1080/00039896.1967.10664815. We included epidemiological studies, experimental animal studies in mammalian species, and mechanistic studies in vivo or in mammalian or bacterial cell lines. The information gained from the assessment will be used by our speech and language therapist to create your childs unique therapy programme. 0000051461 00000 n Mortality from lung cancer was slightly lower than expected for the entire cohort. 37. Registration Dossier: Talc (Mg3H2(Si03)4). All new normative data collected in 2009 - 2011. The preliminary search string was as follows: (talc OR talcum powder) AND (cancer OR carcinogen OR mesothelioma). doi: 10.17226/11908, 9. Additionally, the NTP (19) study involved the use of micronized talc, which has a smaller aerodynamic diameter than mined and milled talcs and talc used in talcum powder products. Health Hazard Evaluation Report: R.T. Vanderbilt Company, Gouverneur, NY. 0000012150 00000 n 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). 1371 0 obj <>stream Northern Italy: An updated cohort study. Inhalation of talc baby powder by hamsters. Further, the physicochemical properties of non-fibrous talc (e.g., inertness) and recent evaluations of potential MOAs indicate talc poses little to no concern for carcinogenic effects in humans, especially at less than lung overload exposures. No statistical tests were reported in either publication. Food Cosmet Tox. 646 0 obj <>stream doi: 10.1177/1091581815586797. Eur Resp J. The TROG-2 is suitable for use by Speech and Language Therapists, Psychologists and Teachers of the Deaf. The literature search and selection process identified 23 primary studies that assessed exposure to talc and pulmonary cancer risks in humans (n = 19) and animals (n = 3). Historical air sampling records (i.e., total respirable dust) also were available at some locations. Learn More. These reported results for exposure and NMRD mortality underscore the magnitude of historical exposures and consequent health risks. Acta Oncol. However, the lung tumors occurred only in female rats exposed at a dose also inducing significant chronic lung toxicity and high lung talc burden, such that the maximum tolerable dose may have been exceeded (21). doi: 10.1006/rtph.1995.1036, 22.

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.

Pickrell JA, Snipes MB, Benson JM, Hanson RL, Jones RK, Carpenter RL, et al. 0000070729 00000 n (6), which reported an alternate pooled Standardized Mortality Ratio (SMR) of 0.242 (90% Confidence Interval [CI]: 0.0121.15) with additional follow up time but no new deaths. Rubino GF, Scansetti G, Piolatto G. Mortality and morbidity among talc miners and millers in Italy. This approval level enables you to buy our assessments requiring A or B qualification levels. Talc is a naturally occurring mineral. The pharmacokinetic data on the fate of inhaled talc indicate rapid clearance from the lung and body after single doses and no translocation of talc to other organs after single or repeated exposures. Our speech and language therapist will assess your childs receptive language abilities and identify where their difficulties lie. However, high quality ratings were rare due to inadequate information on prior employment history among the cohort members, which precluded determining the potential for prior occupational exposure to asbestos. Safety assessment of talc as used in cosmetics. 0000018556 00000 n A nested case-control analysis showed no association of lung cancer with increasing cumulative exposure to talc, after adjusting for smoking, exposure to quartz, and underground work (30). s xr%LD%U\C 0000001995 00000 n Wehner et al. 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. The body of epidemiological evidence is reasonably large and robust for lung cancer and mesothelioma and provides the most weight in the evidence integration, complemented by the number of high-quality experimental animal carcinogenicity bioassays, as well as the lack of convincing mechanistic evidence. Smoking histories were not available for many workers, but all lung cancer cases were known to have been cigarette smokers (31). A flow chart for the overall tiering approach used for cohort studies is provided as an example in Figure 1. 11. (1977) 15:1219.
