Septic arthritis mimicking cellulitis: distinction using radionuclide bone imaging.

Two patients originally diagnosed as having cellulitis involving the dorsum of the foot actually had bacterial arthritis of an underlying joint. In both patients, even after pyarthrosis was suspected, the wrong joint was aspirated. The arthropathies were located by subsequent 99mTc-phosphate bone imaging at a time when roentgenograms were normal. Early diagnosis and aggressive therapy of septic arthritis are essential to prevent joint destruction and osteomyelitis. Radionuclide bone imaging can identify inflammatory joint disease but it cannot specify etiology. In our patients, however, the differential diagnosis was between skin and joint infection. Radionuclide imaging was of great help in making this distinction.

Subacute meningitis heralding a diffuse granulomatous angiitis: (Wegener's granulomatosis?).

Subacute meningitis was the first manifestation of illness in a young man with multisystem disease involving lung, kidney, eye, and central nervous system. Necrotizing granulomatous angiitis was found in tissue obtained at thoracotomy and the diagnosis of Wegener's granulomatosis was suggested. This patient had an excellent functional recovery with cyclophosphamide and prednisone.

Ill-effects of cardiac resuscitation: report of two unusual cases.

Two mishaps associated with closed-chest cardiac resuscitation are presented. One-pneumoperitoneum-became evident during life, created considerable diagnostic difficulty, and evoked treatment that possibly hastened the patient's death. The other-cardiac puncture-appeared at autopsy and its mechanism may be unique.

Acute hematogenous osteomyelitis progressing to septic synovitis and eventual pyarthrosis. The vascular pathway.

A case suggesting sequential infection of bone, synovial membranes, and finally synovial fluid is presented. Hematogenous osteomyelitis manifests itself differently in children than in adults. In children, the avascular epiphyseal cartilage in the growing long bone is an effective barrier to the spread of bone infection to the joint. After obliteration of the growth plate, vascular anastomoses form between metaphysis and epiphysis, and at maturity the entire bone shares a common blood supply with the capsule and synovium of the adjacent joint. In the adult with acute osteomyelitis, contiguous joint infection should be anticipated. In septic arthritis, unless caused by penetrating trauma, the synovium must be infected before the joint fluid. Even when bacterial joint infection is present, repeated arthrocenteses may be required over several days to confirm the diagnosis.
