We have described a patient with fixed bullous eruption, usually associated with severe fever, occurring on five occasions after a series of seven intravenous urograms between 1974 and 1979. Diagnosis was initially obscured because the onset of fever and dermatitis was delayed as long as 72 hours. This is only the second report of true ioderma ascribed to urographic contrast media.
Six weeks after presumptive acute synovial rupture at the knee, a patient was admitted with cutaneous induration over the medial calf. Roentgenograms showed gas shadows within the involved area. A fluctuant area at the center of the indurated mass yielded a Corynebacterium species.

The radiologic manifestations of Reiter disease in 56 patients are described. Although the findings are often nonspecific, certain features are distinctive, particularly when present in combination. These include subtle periosteal bone apposition at bony prominences, the infrequency of regional panarthritis and hip and shoulder involvement, the tendency for destructive arthritis to be confined to small joints, particularly in the feet, and a typically "discontinuous" spondylitis characterized by eccentric, laterally positioned vertebral hyperostoses which tend to bridge around the contigous disk. Attention is drawn to similar hyperostoses which occur above the true sacroiliac joints. The significance of these features, particularly in terms of differential diagnosis, is discussed.
Reiter's disease (RD) is a reactive arthritis syndrome in which arthritis, conjunctivitis, dermatitis, and urethritis are the main features. It may be an acute and self-limited disease or it may cause severe debilitation. It generally follows an infectious episode, such as Shigella dysentery or nonspecific urethritis. Recent evidence has shown that patients in whom RD develops have a genetic disposition since the presence of HLA-B27 correlates highly with RD. Therapy of RD involves supportive care.
Pneumococcal pyarthrosis was documented in seven and ten joints, respectively, in two patients with rheumatoid arthritis. The recognition of multiple pyarthrosis superimposed upon rheumatoid arthritis can be difficult. The present cases are compared with eight previously reported cases of pneumococcal arthritis in patients with rheumatoid arthritis.
A patient with classical rheumatoid arthritis presented with a primary intracranial histiocytic lymphoma. He had not received cytotoxic drugs and had no evidence for Sjögren's syndrome or immunodeficiency. Previous radiation therapy to the shoulders is regarded as a possible, though unlikely, risk factor.
Two patients were initially seen with culture-positive streptococcal arthritis as an early manifestation of bacterial endocarditis. The organisms were an alpha-hemolytic, nongroup D streptococcus and a beta-hemolytic, group b streptococcus. One patient had a persistent septic monarthritis; the other had migratory arthritis in which a positive synovial culture was followed by a negative culture from the same joint before antimicrobial treatment was started. This experience suggests that some sterile synovial aspirates encountered in patients with bacterial endocarditis may be explained by delay of arthrocentesis.
Two patients with pseudogout developed large meniscal cysts at the knee. In the first case the diagnosis of meniscal cyst was confirmed surically. In the second case, the cyst resolved following thorough aspiration. Polarized microscopy of repeated aspirated from cyst in this case as well as of fluids from the knees of both patients consistently showed positively birefringent rhomboid crystals. X-ray diffraction of fluids from the knee of the second patient identified the crystals as calcium pyrophosphate dihydrate.
A 44 year old man with neglected tophaceous gout developed progressive bony and fibrous ankylosis of the lower leg articulations extending from a toe through the ankle, in spite of three years of otherwise successful therapy.
Four patients with hemarthrosis of the knee, synovial rupture, and ecchymoses are reported. The patients presented with calf pain and swelling and large ecchymoses, which eventually extended to the ankle as a crescent about one or both malleoli. Appreciation of this physical sign, which appears to be characteristic for the hemorrhagic subset of synovial rupture, should alert the physician to the correct diagnosis and steer him away from contraindicated anticoagulant therapy.
The effects of flurbiprofen (150-200 mg daily) and indomethacin (75-100 mg daily) were compared in the management of 26 patients with active ankylosing spondylitis in a parallel, double-blind, and randomized trial of six weeks' duration. No patient in either group withdrew from the study because of lack of efficacy of the drugs. Both drugs were equally effectivein relieving the pain and tenderness of the affected joints. Overall subjective improvement, assessed by the patient and the investigator at the end of the trial, was present in 90% of the patients in the flurbiprofen group and in 75% of the indomethacin group. The mean values of all the spinal motion tests improved in the flurbiprofen group but not in the indomethacin group. Statistically significant improvement of the Schober test was achieved in the flurbiprofen group and of the chest expansion measurement in the indomethacin group. Untoward effects related to the central nervous system and gastrointestinal tract were present in a few patients in both groups.
A patient with ankylosing spondylitis was found to have selective IgA deficiency and a non-heparin, immediate-acting antithrombin (antithrombin V). T cells were decreased, and serum IgG was increased. In vitro synthesis of IgG by peripheral blood lymphocytes was very high. This association of ankylosing spondylitis with the T cell and protein abnormalities is probably fortuitous but does demonstrate that severe spondylitis may evolve in the absence of IgA.
