In both rats and mice, 2-year inhalation exposure to talc was associated with chronic active inflammation and accumulation of macrophages in the lung (19). doi: 10.1080/08958370050029725. 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. 45. t In mice, intra-alveolar macrophages were focally aggregated. (2017) 59:65964. The original standardised version included norms of over 2,000 children and was published in 1983 with slight modifications made in 1989. 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. 0000002271 00000 n

The body of epidemiological evidence does not demonstrate a clear or consistent increase in mortality from lung cancer among talc miners and millers. 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. Additional details of our methodology are provided in the Protocol in the Supplementary material, allowing verification and replication of our review. 0000006564 00000 n
Berlin: Springer-Verlag (1990). Between 6% and 8% of the inhaled dose was deposited in alveoli. One strength of our review is that we drew from the strongest aspects of established methodologies of several organizations' systematic review guidance in an attempt to provide a full and transparent evaluation. Updated Italian cohort data continues to confirm lack of mesothelioma risk in pooled cohort of international cosmetic talc miners and millers.

Stille and Tabershaw (47) updated the earlier cohort study and reported that all workers combined showed a moderate excess of lung cancer deaths (SMR = 1.57; no CI reported) (47).

They said she did well on 1, 2 and 4 of the TALC picture assessment but on level 3 not so well, she got 12 out of a possible 17 and the pass mark was 14. I read on another thread, that children that struggle with level 3 may have ASD. trailer

Env Res. A flow chart for the overall tiering approach used for cohort studies is provided as an example in Figure 1. A systematic approach for evaluating the quality of experimental toxicological and ecotoxicological data. : 80-115. the objective of this paper was to apply systematic review methods to critically evaluate and synthesize the scientific evidence addressing the possible relationship (s) between exposure to talc occupationally and from exposure to talc-containing products (primarily talcum powders and cosmetics) and pulmonary cancers, specifically lung Frequency and concentration of use complete table in FDA format and summary information by exposure type, By clicking accept or continuing to use the site, you agree to the terms outlined in our, Safety Assessment of Talc as Used in Cosmetics. (25) reported that talc did not cause significantly increased frequency of sister-chromatid exchange or increased DNA repair synthesis in rat pleural mesothelial cells, relative to positive or negative controls (16). 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. This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist, using a hybrid systematic review framework that incorporates aspects from several recognized systems.

Note that this route of administration (intratracheal instillation) produces different lung distribution patterns compared to inhalation, which limits its relevance to inhalation exposures to talc in humans. (1990) 17:50513. 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 information gained from the assessment can be used to create an individualised therapy programme as well as be used to tailor specific personalised advice for parents and teachers on how best to communicate with your child.

(27) exposed F344/Crl rats and B6C3F1 mice to unspecified talc via whole-body inhalation and compared tumor development in these animals relative to non-exposed rats and mice as controls. 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). The content and the conclusions of the manuscript are exclusively those of the authors. An additional 10 epidemiological studies were identified through supplemental searches using narrower terms (e.g., lung cancer, mesothelioma, millers, miners) and considering the tertiary literature (reviews, gray literature).

Some of the mines in upstate New York were reported to produce talcs with asbestiform or non-asbestiform amphibole minerals including tremolite and anthophyllite (42, 43, 57).

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. 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). Therefore, the large amount of available animal and clinical data the Panel relied on in assessing the safety of talc only. p. 647-654. European Food Safety Authority.

Further, some aspects of the physiology and function of the respiratory system of rodents (e.g., a delicate balance of pulmonary surfactants, as well as smaller and fewer macrophages relative to humans) make them highly susceptible to high doses of solid particles relative to humans (29).

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). After excluding studies based on exposure route, non-pulmonary outcome, and administration of talc as part of a mixture, three studies remained for study quality evaluation (1719). Int J Toxicol.
