BACKGROUND AND DESIGN Patients with lupus erythematosus, rheumatoid arthritis, and other diseases in which circulating immune complexes occur can develop a papular eruption on the extremities. Terms including Churg-Strauss granuloma, cutaneous extravascular necrotizing granuloma, rheumatoid papules, superficial ulcerating rheumatoid necrobiosis, and(More)
Expanded perlite has been assumed as simple nuisance, however during an accidental spill out in Taiwan, among 24 exposed workers followed for more than 6 months, three developed persisted respiratory symptoms and positive provocation tests were compatible with reactive airway dysfunction syndrome. During simulation experiment expanded perlite is shown to be(More)
Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) is a systemic proliferation of cells that resemble the sinus histiocytes of lymph nodes. Whereas initial reports highlighted the often striking cervical adenopathy, more than 40% of patients have extranodal involvement. Cutaneous lesions are the most common form of extranodal disease,(More)
BACKGROUND AND DESIGN Forty-eight human immunodeficiency virus-infected patients with nonmelanoma skin cancers seen during a four-year period were evaluated in a retrospective, case-control study. Patients were followed up after therapy and recurrence rates were determined. RESULTS One hundred and sixteen nonmelanoma skin cancers were identified, 101 of(More)
OBJECTIVES To characterize human immunodeficiency virus (HIV)-associated granuloma annulare (GA) by clinical, microscopic, and molecular methods and to investigate the role of Epstein-Barr virus infection in the pathogenesis of GA. DESIGN Patients were evaluated clinically, and biopsy specimens of lesional skin were examined by light microscopy.(More)
A 59-year-old man developed grouped erythematous papules on the skin of the right axilla and arm shortly after orthotopic liver transplantation. Histologic changes closely resembled those of acquired tufted angioma, with capillary lobules studding the dermis. The lesions spontaneously involuted over several months. Histopathologic and immunohistochemical(More)
Infundibulocystic basal cell carcinoma (IBCC) is a relatively recently described variant of basal cell carcinoma that is controversial and not universally accepted. Excluding cases of nevoid basal cell carcinoma syndrome, IBCC usually presents as a small, solitary, superficial lesion on the face of older persons. There have been previous reports of(More)
The Coulter VCS is an automated differential counter, which derives a five-part differential count on the basis of differences in cell volume, high frequency conductivity and light scatter. A printed scatterplot relating volume and scatter is readily obtained. Other instruments which use automated cytochemistry can distinguish between AML and ALL, and(More)
The mechanism of the increased haemoglobin (Hb) and erythrocyte survival in continuous ambulatory peritoneal dialysis (CAPD) compared to haemodialysis (HD) was investigated by measuring hexose monophosphate shunt (HMP) activity and reduced glutathione concentration (GSH) in 12 patients--six patients who were stable on CAPD, and six patients who were stable(More)
