On the other hand, Honda et al. It also is worth noting that despite claims that some talcs and therefore some talcum powders contain trace amounts of asbestiform minerals, high occupational exposures leading to large excesses of pneumoconiosis deaths were not associated with increased mortality from lung cancer, and these studies consistently report no excess (in fact, no cases) of malignant pleural mesothelioma. A cohort mortality and nested case-control study of French and Austrian talc workers. (56) reported that the death certificate for the single mesothelioma death in the cohort explicitly mentioned exposure to asbestos; yet no additional information was available regarding this potential exposure (56).

According to information reported under section 71 (2009) 48:646790. In the Vermont cohort, a single mesothelioma death was reported in the latest update; however, this case was identified through a detailed review of death certificates for the cohort (which was not performed for the reference group) in a field on the death certificate different from the conventional field for underlying cause of death (56). 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.

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is no mechanistic rationale for a group ADI for silicates and silicon dioxide and the groupADI established by the SCF is obsolete. 0000015861 00000 n Acta Oncol. 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). 389-92. 0000051461 00000 n Specifically, individual study quality ratings were high overall and the studies rated as high quality for the exposure characterization domain failed to demonstrate exposure-response patterns between occupational talc exposure and lung cancer mortality (30, 49).

Some of the available language therapy treatments are listed below: We offer a wide range of treatments, if you feel that your child could benefit from a certain therapy programme contact our speech and language therapist for more details. 10. In both the talc and chrysotile exposure groups, fibrosis was observed to a similar extent, with minimal to no fibrosis observed in the air-exposed control group. 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). 0000004239 00000 n (1989) 49:23345.

(1967) 14:6637. The body of epidemiological literature evaluating talc exposure and risk of malignant mesothelioma, which consists of highly exposed workers with long follow up periods, fails to demonstrate any increased risk of malignant mesothelioma. 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. Honda et al. 12. No. Based on 130,154 total person-years of follow-up across five cohorts, the authors estimated that the pooled cohorts (30, 51, 53, 56) had 59% and 78% power to detect a 2.5-fold or greater and a 3.0-fold or greater increased risk of mesothelioma, respectively. J Occup Env Med. Consequently, half of the talc workers in the mortality study conducted by Dement et al. Application of Systematic Review in TSCA Risk Evaluations. (2002) 46:57585. WebThe largest portion of ground talc is used in ceramics (37%), followed by paint (19%), paper (10%), roofing (9%), other (9%), plastics (7%), cosmetics (5%), rubber (3%), and Lung cancer risk did not increase with increasing cumulative exposure categories after adjustment for age and years since hire (43).

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. The authors attributed the excess lung cancer to previous employment and smoking (46). Specifically, our findings for pulmonary cancers are consistent with IARC's classification of inhaled talc not containing asbestos or asbestiform fibers as not classifiable as to its carcinogenicity, in that neither identified any clear increase in cancer risk in animals and humans, and no clear MOA for carcinogenesis was identified (4).

Markers of oxidative stress (superoxide dismutase 2) were increased at 100 mg/m3. Because the one malignant mesothelioma in the Vermont cohort was identified following a focused search of death certificates for the cohort but not the referent group, its inclusion results in a conservative bias.

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. 7. Children are asked questions about pictures or sequences they are shown. 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). The 17 occupational cohort study reports evaluated for study quality encompassed talc miners and millers in New York State (4147), Italy (1, 4851), Norway (52, 53), France and Austria (30) and Vermont (5456). (2000) 12:117. 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: 10.1002/ajim.4700170408, 53.

Talc was administered to both species for 6 h per day, 5 days per week, for a total of 20 exposure days at talc concentrations of 0, 2, 6, or 18 mg/m3. The TROG-2 is suitable for use by Speech and Language Therapists, Psychologists and Teachers of the Deaf. Because the case-control studies were nested within cohorts, we did not expect substantive differences in quality. Training, advice, support and strategies for parents, teachers and other professionals. 0000070520 00000 n 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. Similarly, Vermont talc miners and millers encountered talcs free of both asbestiform mineral and significant quantities of free silica (54, 56). 7.2.1 Environmental media, food and drinking Pauluhn J.

Thank you. 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). doi: 10.1016/S0015-6264(77)80317-9. Poorly Soluble Particles/Lung Overload: Technical Report No. Therefore, the large amount of available animal and clinical data the Panel relied on in assessing the safety of talc only. What is paediatric speech and language therapy? We recognize, however, that there still may be areas where further refinement in the approach is possible. Beck BD, Feldman HA, Brain JD, Smith TJ, Hallock M, Gerson B, et al. When considered together, the moderate confidence in study findings, large study populations, long duration of follow up, and consistency of null findings indicate that talc exposure is not associated with mesothelioma. In an OECD Guideline 473 in vitro mammalian chromosome aberration test (rated as a Klimisch score of two), Endo-Capron et al. (2017) 60:82130. (2022). However, macrophage numbers decreased in days 414, and remained decreased, indicative of a chronic effect.

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. doi: 10.1093/oxfordjournals.aje.a114913. Make basic level predications e.g. (1979) 2:27384. Ierardi AM, Best EA, Marsh GM. Generally, aerosolized talc has an alveolar biological half-life of about 710 days in animals. The authors reported a reduced exposure odds ratio (OR = 0.73; CI not reported) for cohort members in the highest cumulative talc exposure group (800 mg/m3-years). 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. EPA.
