Lauro Gomes, 2.000, Santo André, São Paulo, 09060-870, Brasil, Tel +55-114993-5400, Email dafnefm13@gmail.comAbstract: Choroidal osteoma is a rare, benign, osseous choristoma presenting as an orange-yellow, well-defined fundus mass. It presents unilaterally in most cases, has a predilection for the female sex, and favor a juxtapapillary location, becoming clinically manifest when it involves the macula. Almost 60% of eyes with osteoma may suffer significant visual loss. Choroidal osteomas can easily be mistaken for other conditions with similar presentations. We herein report two rare cases presentation of choroidal osteoma: a 74-year-old male with 2-year blurred vision in the right eye (RE) initially misdiagnosed with age-related macular degeneration received intravitreal injections and after a multimodal evaluation, following cataract surgery in RE, confirmed to be choroidal osteoma and a 19-year-old female with a history of choroidal hemangioma presented with blurred vision in her left eye (LE), with examination revealed an irregular orange-yellow lesion along the superotemporal arcade with serous macular detachment, later diagnosed as choroidal osteoma.Keywords: choroidal osteoma, osseous choristoma, visual loss, case reports

Background/Objectives: Misophonia, characterized by strong emotional reactions to specific sounds, poses significant challenges, particularly in academic settings. This study aimed to examine the psychometric properties of the Brazilian version of the MisoQuest in a sample of high school and university students. The primary objective was to assess its reliability and structural validity to enhance understanding of misophonia in young adults. Methods: A total of 549 students (Mean age = 23.2 years, SD = 9.3; 285 females, 260 males, 4 individuals who did not disclose their gender) participated. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were employed to evaluate the MisoQuest. Fit indices for unifactorial and trifactorial models were compared. Internal consistency was assessed using Cronbach's alpha. Results: The EFA suggested a dominant single-factor structure with high factor loadings (ranging from 0.60 to 0.79). However, the CFA revealed excellent fit for both unifactorial (CFI and TLI = 1.00, RMSEA close to zero) and trifactorial models (CFI and TLI = 1.00, RMSEA = 0.037). The MisoQuest demonstrated high internal consistency (Cronbach's alpha = 0.93). Additionally, 4.5% of participants were identified as positive for misophonia based on a predefined cutoff score of 61. Conclusions: The Brazilian version of the MisoQuest is a reliable and valid tool for assessing misophonia. These findings suggest that the instrument may capture multiple dimensions of the disorder. Given the observed prevalence of misophonia and its impact on students, early identification and tailored interventions are crucial for providing adequate support. Further research is needed to refine the tool and expand its clinical utility.

Toxoplasma gondii is a coccidian parasite that infects almost all warm-blooded animals, including birds. Abrolhos is an archipelago of five islands, located in the Atlantic Ocean, 56 nautical kilometers from the south coast of the state of Bahia, northeastern Brazil. Part of this archipelago is a National Marine Park, which is a conservation area protected by the Brazilian government. The objective of this study was to determine the occurrence of T. gondii antibodies in sera of seabird's species Sula spp. and Phaeton spp. from breeding colonies located in the Islands of Santa Bárbara and Redonda, Abrolhos's archipelago. Sera were tested by modified agglutination test, first screened at 1:5 dilution (cut-off point) and the positive samples were titrated at a two-fold serial dilution. Serum samples were obtained from 69 birds of four species: Sula dactylatra (23 birds), Sula leucogaster (19 birds), Phaeton aethereus (25 birds) and Phaeton lepturus (2 birds). Antibodies to T. gondii were found in 24 (34.8%) of 69 seabirds with titers that ranged from 5 to 640. Occurrence value in S. dactylatra was 34.8% (8/23), in S. leucogaster was 47.4% (9/19), in P. aethereus was 28% (7/25) and the 2 P. lepturus were negative. This is the first description of T. gondii antibodies in free ranging seabirds of the orders Suliformes and Phaethontiformes., (Copyright © 2016 Elsevier B.V. All rights reserved.)
