ABSTRACT

To investigate the expression of multiple therapeutic targets in tissue specimens from patients with orbital inflammatory syndromes, the clinical records of 16 patients treated for orbital inflammation between January 2003 and November 2005 for whom tissue blocks were available were reviewed retrospectively. Immunohistochemical staining was performed on archived specimens using commercially available monoclonal antibodies against CD3, CD20, CD22, CD23, CD25, and CD52 antigens. The histologic diagnoses were confirmed, and the immunohistochemical staining patterns were agreed upon by both collaborating pathologists (JLJ and PC-B). The study included 13 women and 3 men who ranged in age from 4 to 79 years (mean, 46 years). The histologic diagnoses were as follows: orbital pseudotumor in six patients; sarcoidosis, three; eosinophilic granuloma, one; necrobiotic xanthogranuloma, one; nonspecified granulomatous inflammation, one; Graves' ophthalmopathy, one; Wegener's granulomatosis, one; and reactive lymphoid hyperplasia, two. One orbital lymphoma specimen and one foreign body reaction specimen were used as controls. CD20 was strongly expressed in all specimens except three (Wegener's granulomatosis, eosinophilic granuloma, and nonspecified granulomatous inflammation specimens), and CD25 was strongly expressed in all specimens except the Wegener's granulomatosis specimen, in which this antigen was only moderately expressed. CD20 and CD25 were strongly or moderately expressed in most of the tested specimens of orbital inflammation. If our findings are confirmed in a larger study, rituximab, which targets CD20, and denileukin diftitox (ONTAK), which targets CD25, should be considered for future clinical trials for orbital inflammatory syndromes.

ABSTRACT

AIMS: To assess the relation between a country's economic developmental status and its prevalence of blindness. METHODS: Available epidemiological data on worldwide visual loss and its causes compiled by the World Health Organization were reviewed. Findings were compared with economic development data from the involved countries and regions. Analysis was completed in view of the socioeconomic status of each country and region. RESULTS: Analysis of the global distribution of blindness indicates a trend of higher prevalence existing in developing countries with lower per capita income. Preventable causes of blindness (that is, cataract, trachoma) are also more prevalent in these countries. CONCLUSIONS: Because economic development is shown to be a factor in blindness, programmes for blindness prevention should not be the only route to the elimination of unnecessary blindness throughout the world. Concomitant economic development is also necessary to reduce and eventually eradicate much of the preventable and avoidable causes of blindness.
