Fluoridation and bone disease in renal patients

1979 | Continuing Evaluation of the Use of Fluorides. AAAS Selected Symposium. Westview Press, Boulder, Colorado. (Johansen E, Taves DR, Olsen TO, Eds.) | Johnson W, Jowsey J, Taves DR. | p. 275-293.
About the Authors: William J Johnson, director of the Mayo Artificial Kidney Center and professor of medicine with the Division of Nephrology at the Mayo Clinic, has been involved in the study of calcium and phosphorus metabolism and renal osteodystrophy, potassium metabolism, and uremic neuropathy. He is past chairman of the Minnesota State Medical Association’s Committee on Dialysis and Transplantation and served on the editorial board of Nephron. He has published over 70 papers in his fiel

A case of thick but brittle bones and instant tea

2010 | Clinical Chemistry | Isbell TS, Villareal-Armamento R. | 56(6):1041-42.
CASE DESCRIPTION A 45-year-old white male was found to have radiographic findings of a diffusely dense appendicular skeleton, mild trabecular thickening, and multiple thoracic compression fractures indicating structural weakness. Bone mineral density was above the expected range for his age on the lumbar spine and femoral neck. Social history was significant for well-water consumption and daily instant-tea ingestion of 68 oz (1.89 L) for the past 10–15 years. Pertinent laboratory data are pre

Recovery from skeletal fluorosis

2007 | Journal of Bone and Mineral Research | Cundy T. | 22(9):1475
Kurland et al.(1) reported a fascinating case of skeletal fluorosis in a man who probably ingested significant quantities of fluoride from toothpaste. They report that after withdrawal of fluoride, there was a short initial period of rapid bone loss, followed by a prolonged period of slow BMD loss from the lumbar spine—such that the Z-score was still +9 some 8 yr later. A patient with skeletal fluorosis has attended my clinic for a similar period. At the age of 53 yr, after having sustained

Fluoride studies in a patient with arthritis

October 9, 1971 | The Lancet | Cook HA. | 298(7728):817.
SIR, A high intake of fluoride (F-) is known to cause severe skeletal fluorosis, but the actual fluoride intake required to produce fluorosis is unknown. I have shown that tea-drinking in Britain causes a high intake in both children and adults, maximum intakes in children surveyed reaching nearly 6 mg daily in unfluoridated areas and nearly 7 mg daily in fluoridated areas. (1) It is possible that fluoride intake from tea may be sufficient to cause fluorosis, and I report here a case which gives
