Purpose:The aim was to compare the power of spectacles donated to a recycled spectacle program to the custom-made spectacle refractive prescriptions dispensed in a developing country. Methods: Two hundred consecutive prescriptions were audited in an optical dispensary in Timor-Leste, a developing nation. These refractions were compared against measurements of 2,075 wearable donated spectacles. We determined how many of the 200 prescriptions could be matched to a donated spectacle measurement, how many donated spectacles could be tried for each prescription and how long it would take to find the matched spectacles. Results: There were 1,854 donated spectacles identified as being suitable for comparison with the 200 refractive prescriptions. Twenty-nine out of 200 prescriptions (14.5 per cent) were matched to at least one pair of donated spectacles. Conclusion: Recycling all spectacles is not cost-effective in a developing country that has the ability to make custom-made spectacles and dispense ready-made spectacles.
Background: Angiofibroma of soft tissue (AFST) is a recently described benign soft tissue neoplasm of adults and children characterised by low-grade spindle cells with a myxoid or collagenous stroma bearing very prominent small vasculature. 1 There is a characteristic but non-diagnostic immunohistochemical pattern. 2 A characteristic AHRR-NCOA2 fusion gene secondary to t(5;8)(p15;q13) is present in approximately two thirds of cases. 3 Aims: We present three cases of AFST encountered at RPAH Tissue Pathology in order to outline and explore the clinical, macroscopic, histopathologic, immunohistochemical, and cytogenetic features of this tumour. Methods: Three cases underwent histopathological and immunohistochemical analysis, as well as presentation at a multidisciplinary soft tissue meeting. One case underwent karyotyping. Results and conclusions: All three tumours were well-circumscribed encapsulated soft tissue spindle cell tumours of the lower limbs with prominent vasculature and myxoid areas. All cases were negative for vascular markers and SMA (blood vessels highlighted only), as well as negative for S100, pancytokeratin, and MUC4. One case had scattered atypical cells interpreted as degenerative atypia; focal atypia has been reported as an infrequent feature of AFST. 1,2 One case underwent cytogenetic analysis, revealing a t(5;8)(p14;q13) translocation. The cases are discussed, making comparisons to the available literature. Histologic mimics and the utility of cytogenetics and fluorescence in situ hybridisation are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
