The body of epidemiological evidence does not demonstrate a clear or consistent increase in mortality from lung cancer among talc miners and millers. 0000009706 00000 n To comment on this thread you need to create a Mumsnet account. 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). Part Fibre Tox. Health Hazard Evaluation Report: R.T. Vanderbilt Company, Gouverneur, NY. The primary literature search for talc exposure and all cancers was performed in PubMed (in April; updated September 2021) and yielded a total of 716 publications. doi: 10.1177/1091581815607068, 29. Talc deposition and effects after 20 days of repeated inhalation exposure of rats and mice to talc. In the time-course evaluation, most findings returned to control levels within 14 days. The TROG-2 is suitable for use by Speech and Language Therapists, Psychologists and Teachers of the Deaf. ORD Staff Handbook for Developing IRIS Assessments. Two animal studies examining inflammation in the lungs reported increased early inflammatory markers. (1993) 64:44956. 42. Draft Systematic Review Protocol Supporting TSCA Risk Evaluations for Chemical Substances Version 1.0: A Generic TSCA Systematic Review Protocol with Chemical-Specific Methodologies. In summary, no excess of malignant mesothelioma has been reported in any of the available epidemiological studies of talc miners and millers heavily exposed to talc. IARC Monographs on the Evaluation of Carcinogenic Risks to Humans, Carbon Black, Titanium Dioxide, and Talc, vol. We also identified several meta-analyses/pooled studies, two large cancer registry-based linkage studies examining cancer risks by occupational group but lacking specific information on individual exposures (32, 33), and several talc pleurodesis studies (3437). Hildick-Smith (1976) in a recent review of the biology of talc points out that domestic talc does not contain impurities, and that people working with this pure talc do not develop pulmonary disease. In: Health Health Related Effects of Phyllosilicates Bignon J, , editors. Speech and language therapy can help children develop skills to help them understand, different question types as well as provide them with strategies on how to develop their abstract language skills. 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. Lung cancer mortality was slightly elevated, but did not achieve statistical significance, in the French (SMR = 1.23; 95% CI: 0.761.89) and Vermont (SMR = 1.44; 95% CI: 0.982.03) talc miners and millers but was close to unity for the Austrian (SMR = 1.06; 95% CI: 0.432.19), Italian (SMR = 1.02; 95% CI: 0.821.27) and Norwegian (SIR = 1.17; 95% CI: 0.731.79) talc miners and millers (1, 30, 53, 56). Risk Science Institute ILSI. 0000059774 00000 n Tox Pathol. Exposure characterization was considered the most critical study quality domain in the quality evaluation of lung cancer studies. Visuospatial [Score 0-5] Updated 20/11/2012 . Historical air sampling records were used to estimate cumulative dust exposure for each worker. I have just had a review of his statement and they are concerned about his TALC 2 results he scored level 2 and they have said he should be at level 4, They said he has no imagination and is forgetful, he finds English confusing and he does not understand it but is good at spelling. Talc was also negative in a companion host-mediated mutagenicity assay using male ICR mice injected with Salmonella typhimurium and Saccharomyces cerevisiae, with and without metabolic activation (16). Markers of oxidative stress (superoxide dismutase 2) were increased at 100 mg/m3. talc products.14 The requested labeling was a warning that talcum powder causes cancer in laboratory animals; frequent talc application in the female genital area increases the risk of ovarian cancer. Requires the child use their own knowledge to: Involves the child to have the ability to think about the future and their past to be able to: Children who have concrete thinking often struggle with concepts and words that arent physically present, or have one specific meaning or explanation, or can change. The available data indicate that talc dust exposure in the modern mining of cosmetic grade talc does not appear to be injurious to health and the significantly lower 11. Markers of inflammation also have been observed in the lungs of rats after talc exposure, but one of the only available mechanistic studies utilized a route of exposure (i.e., intratracheal instillation) that is not comparable to inhalation exposures. It is used by the speech and language therapist to identify what types of questions and abstract language your child may be struggling with. doi: 10.1080/08958378.2017.1392656. They also concluded [t]here is limited evidence in experimental animals for the carcinogenicity of talc not containing asbestos or asbestiform fibers. This review is now 12 years old, and several studies and reviews on talc exposure and pulmonary cancer risk have been published since the 2010 IARC Monograph (1, 5, 6). Safety Assessment of Talc as Used in Cosmetics. Try a new one! 7. 41. (1982) 24:4804. @$` g Childrens understanding of abstract language is tested through their use of verbal reasoning. All studies were screened and evaluated by two independent reviewers, and any discrepancies discussed and resolved. 0000055411 00000 n Cause-specific mortality and cancer morbidity in 390 male workers exposed to high purity talc: A six-decade follow-up. EFSA journal. Any product that may be evaluated in this article, or claim that may be made by its manufacturer, is not guaranteed or endorsed by the publisher. Of three experimental animal studies of inhaled talc, only one mesothelioma was reported in a strain of rats prone to spontaneous mesothelioma. 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. Authors KM, WT, MC, and AI have been retained as expert witnesses on behalf of defendants in litigation matters in which it has been alleged that products containing talc caused mesothelioma or other cancers. Kleinfeld M, Messite J, Zaki MH. (2009) 48:646790. 0000070520 00000 n In general, potential confounders such as age were appropriately considered in the statistical analyses, and employment records were used to extract key demographic and work history information. There was one lung carcinoma found in the group exposed to talc for 3 min/day for 30 days, and one lung carcinoma found in the 300-day control group. 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 After eliminating duplicates or studies that were subsequently updated, and applying the inclusion and exclusion criteria determined a priori, 43 epidemiological and six animal studies remained for detailed review. Narrower age bands at younger age groups were used to reflect rapid changes in grammatical understanding and reliability and validity studies were conducted. When stratified by duration of exposure, no exposure-response pattern was found (1, 48, 51). 620 0 obj <> endobj 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). Lung cancer risk did not increase with increasing cumulative exposure categories after adjustment for age and years since hire (43). In order to increase cohort size, the New York cohorts did not limit eligibility based on minimum employment (e.g., 1 year) as is common in cohort mortality studies (42). Overall, the animal studies all employed designs that properly incorporated a control group for comparison, including randomly allocating test animals into experimental groups to reduce potential bias. Occup Env Med. The proposed risk management objective for talc is to decrease inhalation and p 13. Berlin: Springer-Verlag (1990). A 37-year update on mortality patterns in an expanded cohort of Vermont talc miners and millers. In contrast to the lack of excess lung cancer deaths among talc miners and millers, a strong and consistent association has been observed between occupational talc exposure and non-malignant respiratory disease (NMRD), including pneumoconiosis (30, 43, 49, 56). J Occup Med. Figure 2. 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. Received: 08 July 2022; Accepted: 30 August 2022; Published: 11 October 2022. Other studies have reported increases in macrophages and other inflammatory markers after whole-body exposures, but again only with high talc concentrations. Similarly, Vermont talc miners and millers encountered talcs free of both asbestiform mineral and significant quantities of free silica (54, 56). doi: 10.1006/rtph.1995.1036, 22. The evidence for possible carcinogenic mechanisms of talc is limited; however, a genotoxicity MOA confidently can be ruled out. Generally, aerosolized talc has an alveolar biological half-life of about 710 days in animals. A speech and language therapist (frequently referred to as SALT) could carry out a full assessment using CELF which is a diagnostic tool only qualified therapists can #EPA-D-20-031. doi: 10.1080/02841860902913546, 34. 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. The Test of Abstract Language Comprehension is used by the speech and language therapist to assess childrens understanding of abstract language, to determine the level of difficulty. The EFSA Panel on Food Additives and Nutrient Sources added to Food provides a scientific opinion reevaluating the safety of calcium silicate, magnesium silicate and talc when used as food additives, finding that there is no mechanistic rationale for a group ADI for silicates and silicon dioxide and the groupADI established by the SCF is obsolete. hUOgw^AmekpmU7a1.$me0D02bdntU[L./n13{ $( d%0l!Ty\X0yOO#M?]#f(U6>}2^r\)UV__hsqS!z+a These reported results for exposure and NMRD mortality underscore the magnitude of historical exposures and consequent health risks.

Roggli VL, Carney JM, Sporn TA, Pavlisko EN. Albumin, a marker of pulmonary edema, also was increased. There was a single occurrence of malignant mesothelioma in a high-dose male rat; however, aging F344 rats have been reported to develop spontaneous mesotheliomas (22). p. 35763. Kleinfeld and coworkers published two proportionate mortality studies on miners and millers in upstate New York potentially exposed to talc with asbestiform or non-asbestiform amphibole minerals, largely in response to reports of fibrogenic pneumoconiosis (44, 45). Thank you. %PDF-1.6 % Lung tumors occurred at very high administered doses that appeared to cause particle overload and using micronized talc (not typical of talc mining or milling exposures, or of cosmetic talcum powder products), limiting the ability to extrapolate these findings to relevant exposures in humans. 631 0 obj <>/Filter/FlateDecode/ID[<166AC119B1656D9BFB80A0EC76A47BBB><33215A8A902138498BC011EEBA38DDC5>]/Index[620 27]/Info 619 0 R/Length 78/Prev 882784/Root 621 0 R/Size 647/Type/XRef/W[1 3 1]>>stream Email 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).

Chemically, talc is a hydrous magnesium silicate with a chemical formula of Mg 3 Si 4 O 10 (OH) 2. Talc has many uses in cosmetics and other personal care products. For example, it may be used to absorb moisture, to prevent caking, to make facial makeup opaque, or to improve the feel of a product. Although these studies overall were considered to be of high quality, there were some important deficiencies that limited their utility, which are discussed below.

The Developmental Assessment of Young Children Second Edition (DAYC-2) is a popular test used to identify children with possible delays in five different domains. Bronchioalveolar lavage (BAL) fluid was collected and assessed at 1 day post exposure (all doses) or 1, 4, 7, and 14 days after talc administration (3.75 mg/100 g). In summary, lung cancer mortality was not elevated among most of the cohorts of talc miners and millers exposed to high levels of respirable talcs and accessory minerals.
