Summary and Conclusions
1. Results of surveys made in Oklahoma Panhandle on Chronic Fluorine Intoxication was stated, the endemic areas located, the mottled enamel index derived, the fluorine content of the water supply of the different areas given along with the depth of the wells, along with the findings on physical examinations of those afflicted with this condition.
2. That there is evidence which indicates that there is a definite relation between chronic fluorine poisoning as detected by
Diagnosis
The differential diagnosis based on the imaging findings included ossification of subperiosteal hematomas, ectopic calcification in the setting of a connective tissue disorder, and periostitis deformans secondary to fluoride intoxication. Laboratory assays were requested by the patient’s rheumatologist, which were notable for a mildly elevated alkaline phosphatase level (216 U/L, reference range=40–115 U/L) and a markedly elevated serum fluoride level (3.9 mg/L, normal range <
Tea drinking remains popular in the United States and increasingly is suggested to promote health. We caution that skeletal fluorosis can result from consumption of excessive amounts of instant tea because of substantial fluoride levels in some commercial preparations.
Case report
A 52-year-old white woman consulted in 1998 for dense lumbar vertebras discovered after twisting her back. Spinal discomfort and stiffness for 5 years reflected “disc disease.” She had never had a fracture. Chest
All cases of chronic fluoride intoxication with radiculomyelopathy have been previously reported from India (1, 2). This paper describes a patient with clinical, necropsy, and toxicologic findings of this disorder, whose problem is of special interest because he lived in an area where cases of advanced fluorosis would not be expected.
CASE REPORT
A 64-year-old white male was admitted to the Veterans Administration Hospital, McKinney, Tex., on May 11, 1962, because of severe respiratory d
