RESUMO
BACKGROUND: Nephrogenic fibrosing dermopathy (NFD), a rare fibrosing condition of the skin, occurs in patients with renal failure. Worldwide, 215 cases have been reported, but none of them are from Canada. CASE REPORT: A 71-year-old woman with hypertensive vasculopathy and renal failure, hypothyroidism, deep vein thrombosis, and a previous abdominal aneurysm repair presented with the rapid development of indurated skin over her arms and legs. These skin changes developed 5 months after starting hemodialysis. BIOPSY RESULTS: Skin biopsies demonstrated thickened collagen bundles in the dermis with extension into the subcutaneous tissue and minimal increased mucin production. There were increased fibroblastic cells that were immunohistochemically CD34 positive. CONCLUSIONS: This patient has the clinical and pathologic features of NFD. Interestingly, this patient had a history of vein thrombosis and vascular surgery, emphasizing the possible role these features may play as instigators of fibrosis in this disease.

OBJECTIVE: To critically review the body of literature that refutes or supports the role of antimalarials in the exacerbation of psoriasis. METHODS: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were reviewed to identify English-language publications from 1966-2005 examining the role of antimalarials in the exacerbation of psoriasis. A total of 374 articles were identified, of which 32 studies met the inclusion criteria. All available clinical trials or reported cases of the use of antimalarials for patients with psoriasis were included. Data from clinical studies were summarized according to the level of evidence and the outcome of the study. Data were entered into a standardized data extraction form by two independent reviewers. RESULTS AND CONCLUSION: No randomized trial evidence was found. Only one cohort study was available for review. A total of 31 case series and case reports were obtained. There is no strong evidence to refute or support the role of antimalarials in the exacerbation of psoriasis. Controlled trials of antimalarial therapy and its effect on psoriasis are warranted.

Between the summer of 1993 and August 2001, members of the ACS Division of Chemical Education's Committee on Computers in Chemical Education (CCCE) managed the online facilities for 17 online conferences. One more conference will occur during fall 2001, and several additional conferences are planned for the future. This article describes the history and the nature of these online conferences, including the advantages and disadvantages of the online format.
