Objective: To estimate the prevalence of beryllium sensitization among former and current Department of Defense workers from a conventional munitions facility.
Methods: Participants were screened by using Beryllium Lymphocyte Proliferation Test. Those sensitized were offered clinical evaluation for chronic beryllium disease.
Results: Eight (1.5%) of 524 screened workers were found sensitized to beryllium. Although the confidence interval was wide, the results suggested a possibly higher risk of sensitization among workers exposed to beryllium by occasional resurfacing of copper-2% beryllium alloy tools compared with workers with the lowest potential exposure (odds ratio = 2.6; 95% confidence interval, 0.23-29.9).
Conclusions: The findings from this study suggest that Department of Defense workers with low overall exposure to beryllium had a low prevalence of beryllium sensitization. Sensitization rates might be higher where higher beryllium exposures presumably occurred, although this study lacked sufficient power to confirm this.

Sarcoidosis in Beryllium Exposed Workers: A Case-Case Study.

Background: Despite the utility of the beryllium lymphocyte proliferation test (BeLPT), distinguishing sarcoidosis, a disease of unknown etiology, from chronic beryllium disease (CBD), has long posed a diagnostic challenge. It is unclear if beryllium-exposed sarcoidosis cases (Be-exp-Sarc) are clinically distinct from CBD, or are misdiagnosed cases of CBD.
Methods: We performed a case-case study of 40 beryllium-exposed individuals diagnosed with Be-exp-Sarc compared to 40 frequency-matched CBD cases.

Beryllium silicate, recognized as the mineral phenakite (BeSiO), is a prevalent constituent in Earth's upper mantle. This study employs density-functional theory (DFT) calculations to explore the structural, mechanical, dynamical, thermodynamic, and electronic characteristics of this compound under both ambient and high-pressure conditions. Under ideal conditions, the DFT calculations align closely with experimental findings, confirming the mechanical and dynamical stability of the crystalline structure.
