Objective: To investigate the role of postgraduate clinical training at the emergency department of Tenri Hospital in teaching the diagnostic process in the general outpatient department.
Method: Patients seen by 11 first-year residents at the emergency department were consecutively registered with summary sheets. Further information was added, and an analysis was performed of: 1) the distribution of chief complaints in the emergency and general outpatient departments and 2) initial diagnoses and the diagnostic process in the emergency department and the final diagnoses.
Results: The distributions of chief complaints in 89 cases in the emergency department and in 183 cases in the general outpatient department were closely correlated (p=0.0016). Diagnoses in the emergency department were correct in 58% of cases. Treatment was incorrect in 3% of cases.
Conclusion: The distributions of chief complaints in the emergency and general outpatient departments were similar. In our hospital the emergency department plays a major role in postgraduate clinical training by teaching the diagnostic process for the general outpatient department. Clinical management, including decision making for further tests and consultation, in the emergency department by first year residents did lead to any major adverse events.

Objective: Cardiac arrest (CA) has been observed in some patients with Takotsubo syndrome (TTS), most of whom had CA at the initial presentation of TTS. The objective of this report was to discuss the factors underlying the onset of this syndrome.Case presentation: A 72-year-old woman with refractory antineutrophil cytoplasmic autoantibody-associated lung disease was referred to our hospital. Twenty minutes after bronchoscopic examination, cardiopulmonary arrest suddenly occurred. Resuscitation immediately resumed her heartbeat and spontaneous breathing. Subsequent 12-lead electrocardiography, echocardiography, and left ventricular angiography revealed TTS.Conclusion: This case indicates that bronchoscopy can cause severe TTS, especially in patients with systemic inflammation.
