ABSTRACT
OBJECTIVE: To evaluate the rheumatic complications in patients with myelodysplastic and myeloproliferative diseases. METHODS: A retrospective chart review of patients with a rheumatic disease and either a myelodysplastic or myeloproliferative disorder diagnosed on bone marrow examination. RESULTS: Nine patients were identified, 5 with myelodysplastic and 4 with myeloproliferative disorders. Polyarthritis was the most common rheumatic presentation, occurring in 6 patients with a positive rheumatoid factor in 4. Necrotizing vasculitis complicated the course in 3 patients. Autoantibodies and hypergammaglobulinemia were present in the majority of patients. CONCLUSION: There is an association between hematologic disorders caused by proliferation of bone marrow derived pluripotent stem cells and rheumatic disorders.

Only 4% of upper gastrointestinal bleeding in the elderly is due to ulcerative esophagitis, and only rarely has nonsteroidal antiinflammatory drug (NSAID) related esophageal bleeding been reported. We describe a case of NSAID induced ulcerative esophagitis in an 87-year-old woman with documented esophageal dysmotility.

The use of pantographic tracings of mandibular movements is an important aspect of clinical diagnosis and treatment planning in prosthodontics. This study compared an average value system using a Quick Analyzer and computer-generated analogs to an Analog Selector, a device developed as an alternative method for determining the amount of laterotrusive movement and condylar inclination using a lateral interocclusal check record technique. The Quick Analyzer system produced more accurate and more consistent recordings than the Analog Selector. Both methods can be considered as excellent tools for teaching, diagnosis, and treatment planning.

Two different porcelain systems were compared over the B1 to B2 shade ranges visually and spectrophotometrically. Six samples of each porcelain were made by blending weighed increments of opaque and body porcelain and firing the blended compositions onto Option metal disks according to manufacturer's instructions. Compositional blends varied incrementally by 20% in steps. Selective blending of porcelain shades was shown to have an effect in improving the range of choices within the shade guide system. The human eye was capable of detecting small-step changes between two steps of the Vita shade guide. Systematic color changes occurred with compositional changes between B1 and B2. It appears from the overall results observed that a desired blending of porcelains at smaller intervals than full shade guide steps could be done more easily with Jelenko than with Vita porcelain. The visual rankings agreed more closely with the manufacturer's expectations than did the instrumental measurements.
