A case of rapidly progressive disease and pulmonary hypertension due to chronic cosmetic talc inhalation is presented. Although an uncommon cause of pulmonary hypertension, talc, especially through intravenous administration, should be included in the etiology of parenchymal pulmonary hypertension. In our case talc inhalation was inadvertent, causing fulminant disease leading to the patient's death. To our knowledge, this is the first case of inadvertent talc inhalation causing death in adult patient.

A review of the mesotheliogenic potency of cleavage fragments found in talc.
Toxicol Ind Health

Benchmark Risk Group, Chicago, IL, USA.
It has long been recognized that amphibole minerals, such as cleavage fragments of tremolite and anthophyllite, may exist in some talc deposits. We reviewed the current state of the science regarding the factors influencing mesotheliogenic potency of cleavage fragments, with emphasis on those that may co-occur in talc deposits, including dimensional and structural characteristics, animal toxicology, and the most well-studied cohort exposed to talc-associated cleavage fragments. Based on our review, multiple lines of scientific evidence demonstrate that inhaled cleavage fragments associated with talc do not pose a mesothelioma hazard.

Introduction: Tissue from a 77-year-old man diagnosed with mesothelioma was referred with a request for identification of the presence of fibrous structures in tissue samples. The individual's work history including working as a "mucker" at a specific "industrial" talc mine.
Methods: Ferruginous bodies in the tissue digests as well as asbestos fibers were found.
Occupational exposure to cosmetic talc and mesothelioma in barbers, hairdressers, and cosmetologists: A systematic review of the epidemiology.

Benchmark Risk Group, Chicago, IL, USA.
Inhalation exposure to cosmetic talc has generated much scientific debate regarding its potential as a risk factor for mesothelioma, a rare, but fatal cancer. Barbers, hairdressers, and cosmetologists have regularly used cosmetic talc-containing products, but the collective epidemiological evidence for mesothelioma in these occupations has yet to be described. As such, we conducted a systematic review of PubMed and the National Institute for Occupational Safety and Health's (NIOSH) Numbered Publications list to identify original epidemiological literature reporting measures of association between these occupations and incidence of or death from mesothelioma.

The purpose of this review is to elucidate how dimensional and durability characteristics of high aspect ratio nanomaterials (HARN), including carbon nanotubes (CNT) and metal nanowires (MeNW), contribute to understanding the fiber pathogenicity paradigm (FPP), including by explaining the structure-activity relationships (SAR) of a diverse range of natural and synthetic elongate materials that may or may not contribute to mesothelioma development in the lung. While the FPP was originally developed to explain the critical importance of asbestos and synthetic vitreous fiber length, width, aspect ratio and biopersistence in mesothelioma development, there are a vast number of additional inhalable materials that need to be considered in terms of pathogenic features that may contribute to mesothelioma or lack thereof. Not only does the ability to exert more exact control over the length and biopersistence of HARNs confirm the tenets of the FPP, but could be studied by implementating more appropriate toxicological tools for SAR analysis.

There are approximately 400 inorganic minerals in the Earth's crust, some of which can be encountered as elongate mineral particles [EMPs] with dimensional characteristics similar to the six minerals known as asbestos and other asbestiform amphiboles with established human pathogenicity. In addition, the rapidly developing field of nanotechnology is producing an ever-increasing array of high aspect ratio engineered nanomaterials [HARNs] with physical dimensions and biodurability similar to the asbestos fiber types with recognized pathogenic potential. Many of these non-asbestos/non-asbestiform EMPs and HARNs with the potential for aerosolization into the breathing zones of workers and in individuals in non-occupational environments have not yet been thoroughly studied with respect to their potential human pathogenicity, a fact which obviously poses concerns for both occupational health and public health professionals.
