A 25-year-old man with insulin-dependent diabetes mellitus (IDDM) visits the neurology clinic complaining of recurrent episodes of collapsing.

He does not believe that he loses consciousness during these episodes and has observed that emotional situations, particularly when he is laughing, can trigger the attacks. He has been feeling anxious and depressed lately, sleeping poorly with frequent nightmares.

His diabetes control has been poor in the past few months, and he has recently altered his insulin regimen to try to achieve better control. He has a sister who has a history of febrile convulsions.

You are consulted for advice on a 55-year-old man who visited his primary care physician 12 weeks after experiencing an inferior myocardial infarction. He has been experiencing persistent low mood that fluctuates throughout the day, tearfulness, and hopelessness. He has lost 6 kg of weight in the past 3 months, and his BMI is currently 19. Although he has fleeting thoughts of suicide, he assures you that he would not act on them as he does not want to cause any harm to his family. The GP informs you that he was diagnosed with depression 20 years ago after an overdose of paracetamol and was prescribed Citalopram.

Aside from the recent MI, the patient also has a diagnosis of Atrial Fibrillation, for which he is taking warfarin. He has been experiencing epigastric pain for the past 2 years, and an OGD 1 year ago revealed that he required treatment for a duodenal ulcer with adrenaline.
