    Differences between apoplexy and Sheehan. What’s apoplexy? I told you that the-the pathogenesis that it shares with would be more or less with massive haemorrhage into the adrenals. That’s Waterhouse–Friderichsen, completely different. But, this is acute haemorrhage into the pituitary tumour resulting in what? Good. Pituitary insufficiency. There will be sudden headache because now, literally, sella’s filling up with blood so very quickly. It’s going to be a sudden headache and the fact that the optic chiasm is been affected or compromised resulting in bitemporal hemianopsia. It might also have issues with cranial nerves III oculomotor, trochlear 4 and then maybe something like your 6 abducens, meaning to say you’re going to have visual issues. With this sudden rush of blood into your sella, this is not about you going in there and removing a tumour. This is about you relieving that pressure ASAP. Once again, when this is taking place, what’s the most important hormone that you’re always paying attention to? It’s the cortisol, cortisol, cortisol. In addition, understand that the pituitary… Do not, I mean, when there’s talk about insufficiency, do not just restrict yourself to the anterior pituitary. Your patient might not have ADH, may result in symptoms of what? Central diabetes insipidus. Are we clear? Are we clear? Most dangerous of them all would be your secondary adrenal insufficiency due to lack of ACTH. So, what’s your treatment? Please make sure that you treat your patient, manage, manage, manage. Glucocorticoid, glucocorticoid, glucocorticoid. I cannot stress that enough. There will be certain interesting topics that we’ll walk through there. When we start talking about the most common cause of Cushing in the United States is iatrogenic, isn’t it? Exogenous, factitious, all the same thing. And we’ll talk about a very important scenario in which you really want...
