Burton Line
Burton's line, also known as the Burton line or Burtonian line, is a medical sign, clinical sign found in patients with chronic lead poisoning. It is a very thin, black-blue line visible along the margin of the gingiva, gums, at the base of the teeth. The sign was described in 1840 by Henry Burton (physician), Henry Burton: A similar line, the "Bismuthia, bismuth line", occurs in people who have ingested bismuth compounds; bismuth, however, is of very low toxicity.

Medical Sign
Signs and symptoms are the observed or detectable signs, and experienced symptoms of an illness, injury, or condition. A sign for example may be a higher or lower temperature than normal, raised or lowered blood pressure or an abnormality showing on a medical scan. A symptom is something out of the ordinary that is experienced by an individual such as feeling feverish, a headache or other pain or pains in the body. Signs and symptoms Signs A medical sign is an objective observable indication of a disease, injury, or abnormal physiological state that may be detected during a physical examination, examining the patient history, or diagnostic procedure. These signs are visible or otherwise detectable such as a rash or bruise. Medical signs, along with symptoms, assist in formulating diagnostic hypothesis. Examples of signs include elevated blood pressure, nail clubbing of the fingernails or toenails, staggering gait, and arcus senilis and arcus juvenilis of the eyes. Indicati ...

Lead Poisoning
Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. The brain is the most sensitive. Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, and tingling in the hands and feet. It causes almost 10% of intellectual disability of otherwise unknown cause and can result in behavioral problems. Some of the effects are permanent. In severe cases, anemia, seizures, coma, or death may occur. Exposure to lead can occur by contaminated air, water, dust, food, or consumer products. Lead poisoning poses a significantly increased risk to children as they are far more likely to ingest lead indirectly by chewing on toys or other objects that are coated in lead paint. The amount of lead that can be absorbed by children is also higher than that of adults. Exposure at work is a common cause of lead poisoning in adults with certain occupations at particular risk. Diagnosis is typically by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gingiva
The gums or gingiva (plural: ''gingivae'') consist of the mucosal tissue that lies over the mandible and maxilla inside the mouth. Gum health and disease can have an effect on general health. Structure The gums are part of the soft tissue lining of the mouth. They surround the teeth and provide a seal around them. Unlike the soft tissue linings of the lips and cheeks, most of the gums are tightly bound to the underlying bone which helps resist the friction of food passing over them. Thus when healthy, it presents an effective barrier to the barrage of periodontal insults to deeper tissue. Healthy gums are usually coral pink in light skinned people, and may be naturally darker with melanin pigmentation. Changes in color, particularly increased redness, together with swelling and an increased tendency to bleed, suggest an inflammation that is possibly due to the accumulation of bacterial plaque. Overall, the clinical appearance of the tissue reflects the underlying histology, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Burton (physician)
Dr Henry Burton (27 February 1799 – 10 August 1849) was a British physician and chemist, who is famous for his identification of blue discolouration of the gums, the eponymous Burton line, as a symptom of lead poisoning. Family Henry Burton was a son of the London property developer James Burton and his wife Elizabeth Westley (1761 – 1837). Henry was a brother of the gunpowder manufacturer William Ford Burton, the architect Decimus Burton, and the Egyptologist, James Burton. As the ''Cambridge Alumni Database identifies'', some sources, including the entry for ''Henry Burton'' in the Royal College of Physicians’s ''Lives of the Fellows'', incorrectly state that Henry Burton was the son of one ‘John Burton’. This is incorrect: he was the son of the aforementioned James Burton. On his father's side, his great-great grandparents were Rev. James Haliburton (1681–1756) and Margaret Eliott, daughter of Sir William Eliott, 2nd Baronet and aunt of George Augustus Eli ...

Bismuthia
{{Short description, Medical condition Bismuthia is a rare dermatological condition that results from the prolonged use of bismuth. Much more rarely than with silver, bismuth may produce a generalized persistent skin discoloration resembling argyria. The conjunctivae and oral mucosa, as well as skin, are commonly afflicted by the condition. Pigment granules are evenly scattered through the dermis, producing a blue, or bluish gray skin color by the scattering phenomenon. It is extremely rare, and as a consequence is poorly understood by modern medicine. Special stains and spectroscopic methods must be utilized for identification of skin pigments affected by bismuth. Usually, bismuth produces a black line, due to bismuth sulfide, along the gums, near the teeth, similar to the Burton's line which can be found in lead poisoning. This is not likely to occur if the gum is edentulous or the gum and the teeth normal. It is more common when gingivitis and carious teeth are present. Bismuth e ...

Bismuth
Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic and antimony. Elemental bismuth occurs naturally, and its sulfide and oxide forms are important commercial ores. The free element is 86% as dense as lead. It is a brittle metal with a silvery-white color when freshly produced. Surface oxidation generally gives samples of the metal a somewhat rosy cast. Further oxidation under heat can give bismuth a vividly iridescent appearance due to thin-film interference. Bismuth is both the most diamagnetic element and one of the least thermally conductive metals known. Bismuth was long considered the element with the highest atomic mass whose nuclei do not spontaneously decay. However, in 2003 it was discovered to be extremely weakly radioactive. The metal's only primordial isotope, bismuth-209, experiences alpha decay at such a mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
