Uncommon presentations of angiofibroma in sinonasal tract: a two-case report/ Apresentações incomuns de angiofibromas no trato nasossinusal: relato de dois casos
Juvenile nasopharyngeal angiofibroma (JNA) are rare, histologically benign, but locally aggressive, vascular tumors of the nasopharynx that affects predominantly male adolescents, its origins from other sites is denominated extranasopharyngeal angiofibroma (ENPA), which is an even rarer entity afflicting more females and young adults, representing a diagnostic and therapeutic challenge to rhinologists. In this report we present 2 cases of similar clinical presentation, with unilateral nasal obstruction and previous episodes of nasal bleeding. One patient is a 14-year-old male with a soft-tissue mass occupying nasopharynx, middle meatus, and right nasal cavity. The second patient is a 12-year-old male with a soft-tissue lesion rising from right sphenoid sinus and obliterating right nasal cavity, obstructing ipsilateral maxillary sinus, ethmoidal cells, and frontal sinus. Both patients underwent complete endoscopic excision of the lesions, the first one recurred on sphenoid sinus and the second showed no recurrence after 2 years of post-operative follow-up. The unusual sites and presentations make these rare cases and thus worth of reporting

Validation of the collaborative outcomes study on health and functioning during infection times (COH-FIT) questionnaire for adults
BackgroundThe Collaborative Outcome study on Health and Functioning during Infection Times (COH-FIT; www.coh-fit.com) is an anonymous and global online survey measuring health and functioning during the COVID-19 pandemic. The aim of this study was to test concurrently the validity of COH-FIT items and the internal validity of the co-primary outcome, a composite psychopathology "P-score".MethodsThe COH-FIT survey has been translated into 30 languages (two blind forward-translations, consensus, one independent English back-translation, final harmonization). To measure mental health, 1-4 items ("COH-FIT items") were extracted from validated questionnaires (e.g. Patient Health Questionnaire 9). COH-FIT items measured anxiety, depressive, post-traumatic, obsessive-compulsive, bipolar and psychotic symptoms, as well as stress, sleep and concentration. COH-FIT Items which correlated r ≥ 0.5 with validated companion questionnaires, were initially retained. A P-score factor structure was then identified from these items using exploratory factor analysis (EFA) and confirmatory factor analyses (CFA) on data split into training and validation sets. Consistency of results across languages, gender and age was assessed.ResultsFrom >150,000 adult responses by May 6th, 2022, a subset of 22,456 completed both COH-FIT items and validated questionnaires. Concurrent validity was consistently demonstrated across different languages for COH-FIT items. CFA confirmed EFA results of five first-order factors (anxiety, depression, post-traumatic, psychotic, psychophysiologic symptoms) and revealed a single second-order factor P-score, with high internal reliability (ω = 0.95). Factor structure was consistent across age and sex.ConclusionsCOH-FIT is a valid instrument to globally measure mental health during infection times. The P-score is a valid measure of multidimensional mental health
