This case definition is used by the ABLES program, the Council of State and Territorial Epidemiologists (CSTE), and CDCs National Notifiable Diseases Surveillance System (NNDSS). Previously (i.e. from 2009 until November 2015), the case definition for an elevated BLL was a BLL ≥10 µg/dL. The U.S. national BLL geometric mean among adults was 1.2 μg/dL in 2009–2010.Blood lead concentrations in poisoning victims have ranged from 30 to 80 µg/dL in children exposed to lead paint in older houses, 77–104 µg/dL in persons working with pottery glazes, 90–137 µg/dL in individuals consuming contaminated herbal medicines, 109–139 µg/dL in indoor shooting range instructors and as high as 330 µg/dL in those drinking fruit juices from glazed earthenware containers. Prevention
In most cases, lead poisoning is preventable by avoiding exposure to lead. Prevention strategies can be divided into individual (measures taken by a family), preventive medicine (identifying and intervening with high-risk individuals), and public health (reducing risk on a population level).Recommended steps by individuals to reduce the blood lead levels of children include increasing their frequency of hand washing and their intake of calcium and iron, discouraging them from putting their hands to their mouths, vacuuming frequently, and eliminating the presence of lead-containing objects such as blinds and jewellery in the house. In houses with lead pipes or plumbing solder, these can be replaced. Less permanent but cheaper methods include running water in the morning to flush out the most contaminated water, or adjusting the waters chemistry to prevent corrosion of pipes.
Transient lingual papillitis  are painful, hypertrophic, red and white lingual papillae on the tongue. Cause
Transient lingual papillitis can affect males and females as early as 3 years of age. In many cases, the cause is unknown. Some dental professionals believe the inflammation is due to chronic irritation from teeth, fillings, or dental appliances. Stress, poor nutrition, smoking, and alcohol use may also be initiating factors. == References ==
