To assess psychological distress and attachment styles 688 university students of which 370 requested a counselling support responded to Symptom Checklist 90 Revised and Attachment Style Questionnaire. Counselling attending students (vs counselling non-attending students) have a higher psychological risk profile, with more psychological distress and insecure attachment. A marked percentage of students not attending counselling presents psychological distress. In both groups associations emerged between psychopathological problems and insecure attachment. The importance of communication strategies aimed to those students who, albeit non requesting psychological help, display psychological distress is discussed. A patient with undiagnosed tracheomalacia undergoing surgery experienced accidental expiratory central airway collapse after tracheal intubation. Here, we aimed to diagnose tracheomalacia from the preoperative data. A 73-year-old man, scheduled for abdominal surgery, had a clinical history of chronic obstructive pulmonary disease. Preoperative chest computed tomography revealed a lateral narrowing of the tracheal shape. After tracheal intubation, we could not manually ventilate the inflated lung. Emergent bronchoscopy findings, including severe expiratory tracheal collapse, indicated a diagnosis of tracheomalacia. We could fully ventilate the patient by moving the endotracheal tube near the tracheal carina and finally changing it to a double-lumen tube. Airway collapse did not occur under spontaneous breathing. Accidental expiratory central airway collapse could occur in patients with undiagnosed tracheomalacia during surgery. A diagnosis of tracheomalacia should be presumed from a deformed trachea on preoperative imaging and history of chronic obstructive pulmonary disease. Accidental expiratory ce
