Skeletal fluorosis is more common in the developing world, but is occasionally seen in the United States. We present radiographic, scintigraphic, CT, and clinical images of a 26-year-old woman with rapidly progressive, debilitating, polyostotic periostitis, and diffuse osteosclerosis typical of skeletal fluorosis. Laboratory analyses supported this diagnosis. The source of excess fluoride intake was elusive until a concurrent mental health workup revealed the patient's proclivity for inhaling air-duster cans containing difluoroethane. Difluoroethane inhalant abuse is an increasingly reported cause of skeletal fluorosis that astute clinicians should recognize. Discontinuation and sobriety from this toxic agent are essential for recovery.

Groundwater contamination with fluoride is a considerable public health concern that affects millions of people worldwide. The rapid growth of urbanization has led to increase in groundwater contamination. The health risk assessment focuses on both acute and chronic health consequences as it investigates the extent and effects of fluoride exposure through contaminated groundwater.

Fluorine is a strong oxidizing element and excessive intake can have harmful effects, particularly on the body's calcified tissues. Recent studies have demonstrated a link between miRNA and fluorosis. This study aimed to evaluate the time-dose-effect relationship of miR-200c-3p in plasma, urine and cartilage of rats with drinking water fluorosis, and to explore its potential as a biomarker.

Excessive fluoride intake can lead to skeletal fluorosis. Nutritional differences in the same fluoride-exposed environment result in osteosclerosis, osteoporosis, and osteomalacia. DNA methylation has been found to be involved in skeletal fluorosis and is influenced by environment and nutrition.

Fibrodysplasia ossificans progressiva and progressive osseous heteroplasia are genetic forms of heterotopic ossification (HO). Fibrodysplasia ossificans progressiva is caused by ACVR1 gene mutations, while progressive osseous heteroplasia is caused by GNAS gene mutations. Nongenetic HO typically occurs after trauma or surgery, with an occurrence rate of 20-60%.
