Calcium pyrophosphate dihydrate deposition disease and familial hypomagnesemia.

A 40-year-old woman presented with calcium pyrophosphate synovitis and chondrocalcinosis. She was subsequently found to have hypomagnesemia, as did her 22-year-old son. Metabolic studies demonstrated normal gastrointestinal absorption of magnesium, and impaired renal conservation of magnesium without other evidence of renal tubular dysfunction. It seems likely that a genetically determined abnormality of magnesium metabolism was responsible for the occurrence of chondrocalcinosis in this patient.

Longterm follow-up of posterior cervical fusion for atlanto-axial subluxation in rheumatoid arthritis.

Surgical fusion of the upper cervical spine was used to treat atlanto-axial subluxation in 7 patients with rheumatoid arthritis. Postsurgical follow-up was 3 to 16 yr. Despite progressive and often severe radiological changes in the cervical spine, no patient has had a clinical recurrence of neck symptoms requiring further surgery. These results suggest that surgical fusion is successful in the longterm, despite the often dramatic radiological changes which occur in the cervical spine with the passage of time.
