Abstract
PURPOSE The diagnosis of insulinoma can be challenging, requiring documentation of hypoglycaemia associated with non-suppressed insulin and C-peptide, often achieved during a prolonged 72 h fast performed in inpatient setting. Our goal is to predict weather a shorter outpatient fasting test initiated overnight and prolonged up until 24 h could be a sensitive method for diagnosing insulinoma. METHODS We conducted a retrospective monocentric study on subjects admitted to our Unit of Endocrinology from 2019 to 2022 for clinical suspicion of insulinoma and underwent the short fasting test. A comparison between the short test group and the group of subjects who underwent the standard prolonged fasting test (from 2003 to 2018) has also been performed. The short fasting test was initiated by the patient overnight at home and proceeded the following day in outpatient setting (Day Hospital). As in the standard protocol, symptoms and capillary blood glucose (CBG) were strictly monitored. Venous blood was drawn for glycaemia, insulin and C-peptide at admission and at established intervals, in case of symptoms of hypoglycaemia or if CBG ≤ 45 mg/dl, when the fast would be suspended. RESULTS The final sample consisted of 37 patients, with mean age of 44.5 ± 12.6 years (17-74). Short and standard tests were performed in 15 and 22 subjects, respectively. Diagnostic values for insulinoma were observed in 12 patients: in 5/15 who underwent the short fasting test, in 6/22 who underwent the prolonged test and in 1 patient who was initially negative on the short test and subsequently showed diagnostic values during the prolonged test. The diagnosis of insulinoma was achieved in 11/12 cases within 24 h of the beginning of the fast (91.7%). CONCLUSIONS A short fasting test could be a valid, sensitive and reliable first-line workup in diagnosing insulinoma.

Abstract
This study aimed to investigate from the perspective of professional SAMU, the main themes of pre-hospital care (PHC), as subsidies for development of an educational tool focused on the school population. A qualitative study, four meetings in the focus group format, with 19 professional SAMU, in a municipality of Santa Catarina, Brazil. Data were categorized and analyzed with thematic analysis. The results highlighted the main issues or health problems of urgent and emergency tool for modeling and possible application in the context of the School Health Program. It was concluded that the selected topics are critical in the context of the APH, the potential severity and the possibility they involve children, even within the school environment.
