To apply the updated epithelial salivary gland classification scheme to a large cohort of lacrimal gland tumors so as to provide an updated lacrimal gland tumor classification scheme. Methods: A retrospective multicenter cohort study of 118 cases of epithelial neoplasia was undertaken. Main outcome measures included pathologic analysis, subtyping, and survival. Results: Of 118 cases, 17 (14%) were reclassified using the proposed expanded classification scheme based on the current World Health Organization classification of salivary gland tumors. The most frequent neoplasms were pleomorphic adenoma and adenoid cystic carcinoma, of which we highlight more unusual histologic features. Three tumors were found to be unclassifiable with the updated scheme, with 2 having histologically malignant features. Deficiencies and variations in pathologic assessment were noted. Variation in the histologic findings of pleomorphic adenoma and assessment of the extent of invasion of carcinoma ex pleomorphic adenoma were highlighted. Conclusions: The use of the more histologically diverse classification of salivary gland tumors can be successfully applied to the epithelial lacrimal gland neoplasms. This expanded classification system led to reclassifying 14% of cases. Currently, there are no consistent pathologic standards for processing and evaluating these lesions.
Spheno-orbital meningiomas may be classified according to the location and extent of the intraorbital tumor invasion. The different localizations may require different surgical approaches, with different chances of complete removal. The location and extent of the intraorbital tumor results in different recurrence rates, lower for superolateral and inferomedial forms than for orbital apex and diffuse forms.
Purpose: To compare the number of eye surgical procedures performed in Italy during the first month of lockdown with those performed in the same period in 2019. Methods: Review of the surgical procedures performed from 10 March to 9 April 2019 and from 10 March to 9 April 2020 (the first month of lockdown because of the COVID-19 outbreak) at six academic institutional centers of Italy. A distinction was made between urgent procedures: any trauma repairment, trabeculectomy/drainage implant for glaucoma, any operation for rhegmatogenous retinal detachment (RRD) repair, pars plana vitrectomy (PPV) for vitreous hemorrhage (VH), macular hole, or retained lens fragments; elective procedures: corneal transplant, phacoemulsification for cataract extraction, silicone oil removal, and PPV for epiretinal membrane; and intravitreal injections (either anti-vascular endothelial growth factor [VEGF] or dexamethasone) to treat exudative maculopathies. The main outcome measure was the rate of reduction in urgent and elective surgeries performed. Results: Overall, 3624 and 844 surgical procedures were performed from 10 March to 9 April 2019 and from 10 March to 10 April 2020, respectively (−76.7% in 2020 compared to 2019, p < 0.0001). Urgent and elective surgical procedures and intravitreal injections of anti-VEGF drugs or dexamethasone reduced significantly in 2020 in comparison to 2019 ( p < 0.0001 for urgent and elective surgeries and 0.01 for intravitreal injections). Conclusion: A significant reduction in the rate of urgent and elective surgeries and intravitreal injections was recorded during the first month of lockdown compared to the same period in 2019. With this analysis, the authors hope to provide some preliminary insights about the consequences of lockdown for the eyecare system in Italy.
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.
