Atlantoaxial subluxation and hydrocephalus [corrected] in rheumatoid arthritis.

We report a case of rheumatoid arthritis with anterior and vertical atlantoaxial subluxation. Our patient developed severe spastic quadriparesis and pyramidal tract signs. Cephalic computerized tomogram scan showed evidence of evolutive communicating hydrocephalus and the odontoid peg protruding in the posterior fossa.

A single-blind, placebo-controlled study of glycosaminoglycan-peptide complex ('Rumalon') in patients with osteoarthritis of the hip or knee.

A randomized, single-blind, placebo-controlled trial was carried out in 62 patients (30 with osteoarthritis of the hip, 32 with osteoarthritis of the knee) to examine the efficacy of glycosaminoglycan-peptide complex in the treatment of osteoarthritis. Patients received 8-week courses of trial medication, each consisting of intramuscular injections of 3 x 2 ml ampoules per week, alternating with 8-week periods free of trial medication, in addition to conventional drug therapy and physiotherapy, as required. After 2-years' treatment, glycosaminoglycan-peptide-treated patients showed significant improvements, as compared with placebo, in relation to night pain, pain during the day, joint mobility and walking ability.

Passive transfer of unresponsiveness by lymph node cells. Studies on adjuvant disease.

Pretreatment of rats with subarthritogenic doses of mycobacterial adjuvant suppresses the arthritogenic reaction induced by this adjuvant. This unresponsiveness can betransferred to normal syngeneic recipients by viable lymph node cells from unresponsivedonors. Serum from the same donors did not prevent the arthritis.
