Four patients with chondrocalcinosis of the knees volunteered for joint lavage. Preliminary experiments indicated that disodium EDTA and magnesium ions were potent solubilizers of CPPD crystals. The procedure was a therapeutic failure in that insignificant amounts of CPPD were removed and all 4 subjects developed postlavage attacks of pseudogout. It is hypothesized that the acute attack of pseudogout is a result of crystal shedding and may be triggered by any factor that enhances CPPD solubility.

Carcinomatous polyarthritis. The presenting symptom of an ovarian tumor and association with a platelet activating factor.

A 59-year-old white female presented with an acute polyarthritis, fever, and mental confusion. Accompanying blood changes included positive tests for rheumatoid factor and antinuclear factor, anemia, leukocytosis, thrombocytosis, and a circulating factor that stimulated serotonin release from normal platelets. Exploratory laporatomy for a mobile pelvic mass revealed an adenocarcinoma of the left ovary which was completely resected. Shortly thereafter the patient's acute symptoms subsided. After 2 years of follow-up the patient has remained free of symptoms and the serologic changes have reverted to normal.

Lactoferrin and lysozyme levels in synovial fluid: differential indices of articular inflammation and degradation.

Lysozyme and lactoferrin levels were measured in 71 synovial fluids (SF) of patients with traumatic effusions, osteoarthritis, rheumatoid arthritis, pseudogout, septic arthritis, and gout, as well as in 91 synovial fluids graded according to their neutrophil count. Elevated lysozyme levels were found in all the inflammatory arthritides and also in osteoarthritis. Lactoferrin levels were not increased in osteoarthritis but displayed a close correlation to the extent of the inflammatory response as judged by SF neutrophilia. The ratio of lysozyme to lactoferrin decreased progressively with increasing SF neutrophilia. In vitro experiments showed that lactoferrin is released from neutrophils isochronously with lysozyme and beta-glucuronidase. Lactoferrin was not found in hyaline cartilage, a tissue known to contain lysozyme. These results are consistent with belief that SF lysozyme has a major derivation from both cartilage and neutrophils, and that lactoferrin arises only from neutrophils. These findings indicate that the simultaneous measurement of lysozyme and lactoferrin provides a potentially useful index of both joint inflammation and cartilage degradation.

The trichorhinophalangeal dysplasia syndrome: report of eight kindreds, with emphasis on hip complications, late presentations, and premature osteoarthrosis.

The trichorhinophalangeal dysplasia syndrome is characterized by peripheral cone-shaped epiphyses and unusual facies and hair. It is generally considered to be an uncommon dysplasia that presents in childhood. Thirteen cases in eight kindreds are reported. In four patients, the diagnosis was not established until after the 40th year, and it is suggested that the dysplasia may present in adult life and be more common than is generally appreciated. The skeletal stigmata of the syndrome are described, with special reference to hip involvement, and a severe and progressive degenerative arthritis is reported.
