Double vision is a symptom often experienced by patients with neurologic disease. An organized systematic approach to evaluating patients with diplopia needs a foundational understanding of the neuroanatomy and examination of eye movements and ocular alignment. In this episode, Teshamae Monteith, MD, FAAN, speaks with Devin Mackay, MD, FAAN, author of the article “Approach to Diplopia” in the Continuum® April 2025 Neuro-ophthalmology issue. Dr. Monteith is the associate editor of Continuum® Audio and an associate professor of clinical neurology at the University of Miami Miller School of Medicine in Miami, Florida. Dr. Mackay is an associate professor of neurology, ophthalmology, and clinical neurosurgery at Indiana University School of Medicine in Indianapolis, Indiana.

Dr Monteith: This is Dr Teshamae Monteith. Today I'm interviewing Dr Devin Mackay about his article on approach to diplopia, which appears in the April 2025 Continuum issue on neuro-ophthalmology. Welcome to the podcast. How are you? Dr Mackay: Thank you. It's great to be here. Dr Monteith: Congratulations on your article. Dr Mackay: Thank you. I appreciate that. Dr Monteith: Why don't you start off with introducing yourself to our audience? Dr Mackay: So, yeah, my name is Devin Mackay. I'm a neuro-ophthalmologist at Indiana University. I did my residency at what was used to be known as the Partners Healthcare Program in Boston, and I did a fellowship in neuro-ophthalmology in Atlanta. And I've been in practice now for about ten years. Dr Monteith: Oh, wow. Okay. Tell us a little bit about your goals when you were writing the chapter. Dr Mackay: So, my goal with the approach to double vision was really to demystify double vision. I think double vision is something that as trainees, and even as faculty members and practicing neurologists, we really get intimidated by, I think. And it really helps to have a way to approach it that demystifies it and allows us to localize, just like we do with so many other problems in neurology. Dr Monteith: I love that, demystification. So why don't you tell us what got you interested in neuro-ophthalmology? Dr Mackay: Yeah, so neuro-ophthalmology I stumbled on during a rotation during residency. We rotated in different subspecialties of neurology and I did neuro-ophthalmology, and I was just amazed by the exam and how intricate it was, the value of neuroanatomy and localization, the ability to take a complicated problem and kind of approach it as a diagnostic specialist and really unravel the layers of it to make it better. To, you know, figure out what the problem is and make it better. Dr Monteith: Okay, so you had a calling, clearly. Dr Mackay: I sure did. Dr Monteith: You talked about latest developments in neuro-ophthalmology as it relates to diplopia. Why don't you share that with our listeners? Dr Mackay: Yeah. So, you know, double vision is something that's really been around since the beginning of time, essentially. So that part hasn't really changed a lot, but there are some changes that have happened in how we approach double vision. Probably one of the bigger ones has been, we used to teach that with a, you know, patient over the age of fifty with vascular risk factors who had a cranial nerve palsy of cranial nerves 3, 4, or 6, we used to automatically assume that was a microvascular palsy and we just wouldn't do any more testing and we'd just, you know, wait to see how they did. And it turns out we're missing some patients who have significant pathologies, sometimes, with that approach. And so, we've really shifted our teaching with that to emphasize that it's a lot easier to get an MRI, for example, than it ever has been. And it can be important to make sure we're not missing important pathology in patients, even if they have vascular risk factors over the age of fifty and they just have a cranial nerve 3, 4, or 6 palsy. So that's been one change. Dr Monteith: Interesting. And why don't you tell us a little bit about the essential points that you want to get across in the article? Dr Mackay: Yeah. So, I think one is to have a systematic approach to double vision. And a lot of that really revolves around localization. And it even begins with the history that we take from the patients. There's lots of interesting things we can ask about double vision from the patient. For example, the most important thing you can ever ask someone with double vision is, does it go away when you cover either eye? And that really helps us figure out the first question for us as neurologists, which is, is it neurologic or non-neurologic? If it's still there when covering one eye, then it is not neurologic and that's usually a problem for an ophthalmologist to sort out. So that's really number one. And then if it is binocular double vision, then we get into details about, is it horizontal or vertical misalignment? Is it- what makes it better and worse? Is there an associated ptosis or other symptoms? And based on all of that, we can really localize the abnormality with the double vision and get into details about further testing if needed, and so forth. I also love that that approach really reduces our need to rely on things like neuroimaging sometimes when we may not need it, or on other tests. So, I think it really helps us be more efficient and really take better care of patients. Dr Monteith: So definitely that cover/uncover test, top thing there. Your approach- and you mentioned, are you really getting that history, and are there any other kind of key factors when you're approaching diplopia before getting into some of the details? Dr Mackay: Yeah, that's a good question. I think also having some basics of how to examine the patient, because double vision is such a challenging thing. A lot of us aren't as familiar with the exam toolkit, so to speak, of what you would do with a patient with double vision. And so, I go over in the article a bit about a Maddox rod, which is a handy little tool that I always keep in my pocket of my lab coat. It allows you to assign a red line to one eye and a light to the other eye, and you can see if the eyes line up or not. And you don't need any other special equipment, you just need the light in that Maddox rod. That really helps us understand a lot about the pattern of misalignment, which is really important for evaluating double vision. So, for example, if someone has a right 6th nerve palsy, I'll expect a horizontal misalignment of the eyes that worsens when the patient looks to the right and improves when they look to the left. And especially if it's a partial palsy, it's not always easy to see that just by looking at their eye movements. And having a way to really measure the eye alignment and figure out, is it worse or better in certain directions, is really essential to localization, I think, in a lot of cases. Dr Monteith: You caught me. I skipped over that Maddox rod part, even though you spent a lot of time talking about Maddox rods. Kind of skipped over it. So, you're saying that I need one. Dr Mackay: Everyone needs one. I've converted some of our residents here to carry one with them. And yeah, I realize it's a daunting tool at first, but when you have a patient with double vision and their eye movements look normal, I feel like a lot of neurologists are- kind of, their hands seem like they're tied and they're like, oh, I don't know, I don't know what to do at this point. And if you can get some more details with a simple object like that, it can really change things. Dr Monteith: So, we've got to talk to the AAN store and make sure that they have enough of these, because now there's going to be lots of… Dr Mackay: We're going to sell out on Amazon today now because of this podcast. Dr Monteith: Cyber Monday. So, let's talk about the H pattern. And I didn't know it had the- well, yeah, I guess the official name is “H pattern.” In medical school, I mean, that's what I learned. But as a resident and, you know, certainly as an attendee, I see people doing all sorts of things. You're pro-H pattern, but are there other patterns that you also respect? Dr Mackay: It depends on what you're looking for, I think. The reason I like the H pattern is because you get to look at upgaze and downgaze in two different directions. So, you get to look at upgaze and downgaze when looking to the left, and up- and downgaze when looking to the right. And the reason that matters is because vertical movements of the eyes are actually controlled by different eye muscles depending on whether the eye is adducted toward the nose or abducted away from the nose. And so that's why I love the H pattern, is because it allows you to see that. If you just have them look up and down with just a cross pattern, for example, then you really lose that specificity of looking at both the adduction and abduction aspects. So, it's not wrong to do it another way with, like, the cross, for example, but I just think there are some cases where we'll be missing some information, and sometimes that can actually make a difference. Dr Monteith: Well, there you have it. Let's talk a little bit about eliciting diplopia during the neurologic exam. What other things should we be looking out for? Dr Mackay: So, in terms of eliciting diplopia, it really starts with the exam and again, figuring out, are we covering one eye? And figuring out, is this patient still having double vision? It's tricky because sometimes the patients won't even know the answer to that question or they've never done it, they've never covered one eye. And so, if that's the case, I really make them do it in the office with me and it's like, okay, well, are we having double vision right now? Well, great, okay, we are, then we're going to figure this out right now. And we cover one eye and say, is it still double? And that way we can really figure out, are we monocular or binocular? That's always step one. And then if we've established that it's binocular diplopia, then that's when we get into the other details that I mentioned before. And then as far as other things to look for, we're always in tune to other things that are going on in terms of symptoms, like ptosis, or if there's bulbar weakness, or some sensory change or motor problem that seems to be associated with it. Obviously, those will give us clues in the localization as well. Dr Monteith: And what about ocular malalignment? Dr Mackay: Yeah. So ocular malalignment, really, the cardinal symptom of that is going to be double vision. And so, if a patient has a misalignment of the eyes and they don't have double vision, then usually that means either we're wrong and they don't have double vision, or they do have double vision and they, you know, haven't said it correctly. Or it could be that the vision is poor in one eye. Sometimes that can happen. Or, some patients were actually born with an eye misalignment and their brain has learned in a way to kind of tune out or not allow the proper development of vision in one eye. And so that's also known as amblyopia, also known as the lazy eye, some people call it. But that finding can also make someone not experience double vision. But otherwise, if someone's had normal vision kind of throughout their life, they'll usually be pretty aware of when they first notice double vision. It'll be an obvious event for them in in most cases. Dr Monteith: And then the Cogan lid twitch? Dr Mackay: Oh yes, the Cogan lid twitch. So, the Cogan lid twitch is a feature of myasthenia gravis. The way you elicit it is, you have the patient look down. I'm not sure there's a standardization for how long; you want to have it long enough that you're resting the levator muscle, which is the muscle that pulls the upper lid open. And so, you rest that by having them look down for… I usually do about ten or fifteen seconds. And then I have them look up to looking straight forward. And you want to pay careful attention to their lid position as their eye settles in that straight-forward position. What will happen with a Cogan's lid twitch is, the lid will overshoot, and then it'll come back down and settle into its, kind of, proper position. And what we think is happening there is, it's almost like a little mini “rest test” in a way, where you're resting that muscle just long enough to allow some of the neurotransmission to recover. You get a normal contraction of the muscle, but it fades very quickly and comes back down. And that's experienced as a twitch. Dr Monteith: So, the patient can feel it. And it's something you can see? Dr Mackay: Yeah, the patient may not feel it as much. It's usually it's going to be something that the clinician can see if they're looking for it. And I would say that's one of the physical exam findings that can be a hallmark of myasthenia gravis, but certainly not the only one. Some others that we often look for are fatigable ptosis with sustained upgaze. You have the patient look up for a prolonged time and you'll see the lid droop down. So that can be one. Ice pack test is very popular nowadays, and it has pretty good sensitivity and specificity for myasthenia. So, you keep an ice pack over the closed eyes for two minutes and you compare the lid position before and after the ice pack test. And in the vast majority of myasthenia patients, if they have ptosis, the ptosis will have resolved, or at least significantly improved, in those patients. And yet one more sign is, if you find the patient's eye with ptosis and you lift open the eye manually, you'll often see that the other eyelid and the other eye will lower down. So, I'm not sure there's a name for that, but that can be a helpful sign as well. Dr Monteith: Since you're going through some of these, kind of, key features of different neurologic disease, why don't you tell us about a few others? Dr Mackay: Yeah, so another I mentioned in the in the article is measurement of levator function, which is really a test of eyelid strength. And so, that can be helpful if we have- someone has ptosis, or we're not sure if they have ptosis and we're trying to evaluate that to see if it's linked to the double vision, because that really changes the differential if ptosis is part of the clinical situation. So, the way that's measured is you have a patient look down as far as they can. And you get out a little ruler---I usually use a millimeter ruler---and I set the zero of the ruler at the upper lid margin when they're looking down. So, I hold the ruler there, and then I ask the patient to look up as far as they can without moving their head. Where the lid position stops of the upper lid is the new point on the ruler. And so, you measure that and see how much that is. And so, a normal patient may have a value somewhere between, I don't know, twelve or thirteen millimeters up to seventeen or eighteen millimeters, probably, in most cases. Especially if there is an asymmetric lid position, if you find that the levator function is symmetric, then it tells you that the muscle is working fine and that the ptosis is not from the muscle. So then the ptosis may be from dehiscence of the lid margin from the muscle. And so, that's a really common cause of ptosis, and that's often age-related or trauma-related. And we can dismiss that as being part of the symptom constellation of double vision. So, it can be really helpful to clarify, is this a muscle problem, which you'd expect with myasthenia or a third nerve palsy, or is this a mechanical problem with the lid, which is non-neurologic and really should be dismissed? So that can be a really helpful exam tool. Dr Monteith: So, you're just now getting into a little localization. So why don't we kind of start from the most proximal pistol with localization. Give us a little bit of tips. I know they just got to read your article, but give us a few tips. Dr Mackay: So, in terms of most proximal causes, there are supranuclear causes of ocular misalignment. For example, a skew deviation would qualify as that. Anything that's happening from some deficient input before you get to the cranial nerve nuclei, that we would consider supranuclear. So, we also see that with things like progressive supranuclear policy and certain other conditions. And then there can be lesions of the cranial nerve nuclei themselves. So, cranial nerves 3, 4, and 6 all have nuclei, and if they're lesioned they will cause double vision in specific patterns. And then there's also another subgroup, which is known as intranuclear problems with eye alignment. And so, the most common of that is going to be intranuclear ophthalmoplegia. And so that's very common in patients with demyelinating disorders, or it can also happen with strokes and tumors and other causes. And then there's infranuclear problems, which are from the cranial nerve nuclei out, and so those would be the cranial nerves themselves. So that's where your microvascular palsies, any tumor pressing on the nerve in those locations can cause palsies like that, any inflammatory disorder along that course. Then as we get more distal, we get into the orbit, we have the neuromuscular junction---so, the connection between the nerve and the muscle. And of course, that's our myasthenia gravis. And there are rare causes, things like botulinum and tick borne illnesses and certain other things that are more rare. And then, of course, we get to the muscle itself, and there can be different muscular dystrophies, different things like myositis or inflammatory disorders of the orbit or even physical trauma. So, if a patient, you know, had a trauma in trapping an extraocular muscle, that can be a localization. So really, anywhere along that pathway you can have double vision. So, I love to approach it from that perspective to help narrow down the diagnostic possibilities. Dr Monteith: Okay, just like everything? Dr Mackay: Just like all of the rest of the neurology. See, it's not that scary. Dr Monteith: You know, and so, yeah. And then you do a lot more than, you know, a few cranial nerves, right? Dr Mackay: Right. That's right. There's a lot more to double vision than that. I think as neurologists, we get lost if it's not a cranial nerve palsy, we're like, oh, I don't know what this is. And if it's not myasthenia, not a cranial nerve palsy. But it's worth also considering that there are ophthalmologic causes of someone having double vision that we often don't consider. So maybe someone who was born with strabismus, or maybe they have a little bit of a tendency toward an eye misalignment that their brain compensates, for and then it decompensates someday and that now they have a little bit of double vision intermittently, so that those can be causes to consider as well. Dr Monteith: Yeah, well, we'll just have to, you know, request those records from forty years ago. No problem. Dr Mackay: That's right. Dr Monteith: Why don't you also give us a little bit of tip when we're on the wards and we want to teach either a medical student or a resident, or if it's a resident listening, may want to teach a junior resident and seem like a star when approaching a patient with diplopia. Give us some teaching pearls. Dr Mackay: Yeah. So, I would love people teaching more about this at the bedside. I'd say probably the first thing to do would be to equip yourself by recognizing what some of the pertinent questions are to ask someone with double vision. Those things would include, is the double vision worse when looking in a certain direction? Does the double vision go away or not when you cover one eye? What happens when you tilt your head one direction or the other? Is it intermittent or constant? What makes it better? What makes it worse? Those kinds of things can really help us narrow down the possibilities. And then the other thing would be to equip yourself with some tools for examining. And it doesn't have to be physical tools. These can actually be things like, you mentioned the cross-cover test or cover/uncover test. That's described in the article. And I think knowing how to do that properly, knowing how to examine the eye movements properly and how to check for subtle things like a subtle intranuclear ophthalmoplegia, which is also mentioned in the article, being familiar with those things can be a really useful exercise in allowing you to teach others later on. Dr Monteith: Cool. Why don't you tell us about some of the things you're most excited about in the field? Dr Mackay: One of the things about our subspecialty for so long is we really haven't had big data with, you know, big trials and all these things that all the stroke people have. And that's starting to change slowly. There's been, for example, the idiopathic intracranial hypertension treatment trial that was published back in, I think it was 2014. You know, of course we had the optic neuritis treatment trial, back a few decades ago now. Some of the exciting ones coming up, there's going to be a randomized controlled trial looking at different treatments for idiopathic intracranial hypertension that are surgically based. So, for example, comparing venous sinus stenting with optic nerve sheath fenestration. And so, figuring out, is there a best practice for surgical intervention for patients with IIH? So, we're starting to have more trials like that now than I think we've had in the past. And so, it's exciting to get to have an evidence base for some of the things that we recommend and do. Dr Monteith: And what about some of the treatment for diplopia? Like prisms, and where are we with some of that? Dr Mackay: Yeah, great. So, it's a pretty simple concept, but still kind of difficult in practice. I kind of say there are four different ways to treat double vision: you can ignore it, you can patch or cover one eye, you can treat with prisms, and you can treat with eye muscle surgery. And so, those are the main ways other than, of course, treating the underlying disorder if there's a disorder causing double vision. So those are the main ways to treat. In terms of knowing if someone's going to be a candidate for prism therapy, we also have to remember that prisms are really going to be most helpful for when someone's looking straight forward. So, we need to make sure that their double vision is happening when they look straight forward. So, for example, if they're only having double vision looking to the left or to the right, that patient may not benefit from prisms as much as someone who is having double vision when they look straight forward. So that's one thing I look for. And then strabismus surgery is something to be considered if someone is not tolerating prisms and they're not helping and their eye alignment is stable. So, if you think about it, if someone's eye alignment is changing a lot, you're probably not going to want to do surgery for that patient because it's going to keep changing after surgery. And so, if someone's eye alignment is stable for six months or more and they're not getting the benefit they'd like from prisms, then maybe referral to a strabismus surgeon might be something to consider. Dr Monteith: Great. And then, I guess another question is just popping up in my head selfishly. What are your thoughts about patients that get referrals for exercises? Say they have, like, a convergence efficiency or something causing diplopia, maybe after a concussion. Maybe there's not a lot of evidence, but what is your take on exercising? Dr Mackay: Yeah, excellent question. So, there actually is evidence for exercises for convergence insufficiency. So, we know that those do work. Now where exercises are probably not as helpful, or at least not- there isn't an evidence base for them, is really with just about every other kind of eye misalignment in adults. We hear a lot about eye movement therapies for concussion and barely any other acquired misalignment of the eyes as well. And really, the evidence really hasn't shown us that that's helpful; again, with the exception being convergence insufficiency. So, we know that an office-based vision therapy type program for convergence insufficiency does work, but of course it's kind of inconvenient. It can cost money that may or may not be covered by insurance. And so, there are difficulties even with doing that. And so, I often recommend that patients with convergence insufficiency at least try something called pencil push-ups, where they take a pencil at arm's length and they bring it in and exercise that convergence ability. You know, that's a cheap, easy way to try to treat that initially. So yeah, there can be some limited utility for eye muscle exercises in certain conditions. Dr Monteith: My one example. I was- it was fuzzy, but in a different way. So, what do you do for fun? I mean, it sounds like you like to see a lot of eyeballs? Dr Mackay: I do. I like to see a lot of eyeballs. Dr Monteith: When you're not doing these things, what do you do for fun? Dr Mackay: So, people ask me what my hobbies are, and I laugh because my hobby is actually raising children. Dr Monteith: Oh, okay! Dr Mackay: So, my wife and I have eight kids- Dr Monteith: Oh, wow! Dr Mackay: Ages three to thirteen. So, kind of doesn't allow me to have other things right now. I'm sure I'll have more hobbies later on, but no, I really love my kids. And I- they give me plenty to do. There's no shortage of- in fact, they were really, they were really excited about this podcast today. They're so excited that Dad gets to be on a podcast, and so I'm going to have to show this to them later. They're going to be thrilled about it. Dr Monteith: Excellent. Well, thank you so much for being on the podcast. Dr Mackay: Thank you. It's been my pleasure.

Papilledema describes optic disc swelling (usually bilateral) arising from raised intracranial pressure. Due to its serious nature, there is a fear of underdiagnosis; hence, one major stumbling points is correct identification, which typically requires a thorough ocular examination including visual field testing. In this episode, Kait Nevel, MD speaks with Susan P. Mollan, MBChB, PhD, FRCOphth, author of the article “Papilledema” in the Continuum® April 2025 Neuro-ophthalmology issue.

Dr Nevel: Hello, this is Dr Kait Nevel. Today I'm interviewing Dr Susan Mollan about her article Papilledema Diagnosis and Management, which appears in the April 2025 Continuum issue on neuro-ophthalmology. Susie, welcome to the podcast, and please introduce yourself to our audience. Dr Mollan: Thank you so much, Kait. It's a pleasure to be here today. I'm Susie Mollan, I'm a consultant neuro-ophthalmologist, and I work at University Hospitals Birmingham- and that's in England. Dr Nevel: Wonderful. So glad to be talking to you today about your article. To start us off, can you please share with us what you think is the most important takeaway from your article for the practicing neurologist? Dr Mollan: I think really the most important thing is about examining the fundus and actually trying to visualize the optic nerves. Because as neurologists, you're really acutely trained in examining the cranial nerves, and often people shy away from looking at the eyes. And it can give people such confidence when they're able to really work out straightaway whether there's going to be a problem or there's not going to be a problem with papilledema. And I guess maybe a little bit later on we can talk about the article and tips and tricks for looking at the fundus. But I think that would be my most important thing to take away. Dr Nevel: I'm so glad that you started with that because, you know, that's something that I find with trainees in general, that they often find one of the more daunting or challenging aspects of learning, really, how to do an excellent neurological exam is examining the fundus and feeling confident in diagnosing papilledema. What kind of advice do you give to trainees learning this skill? Dr Mollan: So, it really is practice and always carrying your ophthalmoscope with you. There's lots of different devices that people can choose to buy. But really, if you have a direct ophthalmoscope, get it out in the ward, get it out in clinic. Look at those patients that you'd know have alternative diagnosis, but it gives you that practice. I also invite everybody to come to the eye clinic because we have dilated patients there all the time. We have diabetic retinopathy clinics, and it makes it really easy to start to acquire those skills because I think it's very tricky, because you're getting a highly magnified view of the optic nerve and you've got to sort out in your head what you're actually looking at. I think it's practice. and then use every opportunity to really look at the fundus, and then ask your ophthalmology colleagues whether you can go to clinic. Dr Nevel: Wonderful advice. What do you think is most challenging about the evaluation of papilledema and why? Dr Mollan: I think there are many different aspects that are challenging, and these patients come from lots of different areas. They can come from the family doctor, they can come from an optician or another specialist. A lot of them can have headache. And, as you know, headache is almost ubiquitous in the population. So, trying to pull out the sort of salient symptoms that can go across so many different conditions. There's nothing that's pathognomonic for papilledema other than looking at the optic nerves. So, I think it's difficult because the presentation can be difficult. The actual history can be challenging. There are those rare patients that don't have headache, don't have pulsatile tinnitus, but can still have papilledema. So, I think it- the most challenging thing is actually confirming papilledema. And if you're not able to confirm it, getting that person to somebody who's able to help and confirm or refute papilledema is the most important thing. Dr Nevel: Yeah, right. Because you talk in your article the importance of distinguishing between papilledema and some other diagnoses that can look like papilledema but aren't papilledema. Can you talk about that a little bit? Dr Mollan: Absolutely. I think in the article it's quite nice because we were able to spend a bit of time on a big table going through all the pseudopapilledema diagnoses. So that includes people with shortsightedness, longsightedness, people with optic nerve head drusen. And we've been very fortunate in ophthalmology that we now have 3D imaging of the optic nerve. So, it makes it quite clear to us, when it's pseudopapilledema, it's almost unfair when you're using the direct ophthalmoscope that you don't get a cross sectional image through that optic nerve. So, I'd really sort of recommend people to delve into the article and look at that table because it nicely picks out how you could pick up pseudopapilledema versus papilledema. Dr Nevel: Perfect. In your article, you also talk about what's important to think about in terms of causes of papilledema and what to evaluate for. Can you tell us, you know, when you see someone who you diagnose with papilledema, what do you kind of run through in terms of diagnostic tests and things that you want to make sure you're evaluating for or not missing? Dr Mollan: Yeah. So, I think the first thing is, is once it's confirmed, is making sure it's isolated or whether there's any additional cranial nerve palsies. So that might be particularly important in terms of double vision and a sixth nerve palsy, but also not forgetting things like corneal sensation in the rest of the cranial nerves. I then make sure that we have a blood pressure. And that sounds a bit ridiculous in this day and age because everybody should have a blood pressure coming to clinic or into the emergency room. But sometimes it's overlooked in the panic of thinking, gosh, I need to investigate this person. And if you find that somebody does have malignant hypertension, often what we do is we kind of stop the investigational pathway and go down the route of getting the medics involved to help with lowering the blood pressure to a safe level. I would then always think about my next thing in terms of taking some bloods. I like to rule out anemia because anemia can coexist in a lot of different conditions of raised endocranial pressure. And so, taking some simple blood such as a complete blood count, checking the kidney function, I think is important in that investigational pathway. But you're not really going to stop there. You're going to move on to neuroimaging. It doesn't really matter what you do, whether you do a CT or an MRI, it's just getting that imaging pretty much on the same day as you see the patient. And the key point to that imaging is to do venography. And you want to rule out a venous sinus thrombosis cause that's the one thing that is really going to cause the patient a lot of morbidity. Once your neuroimaging is secure and you're happy, there's no structural lesion or a thrombosis, it's then reviewing that imaging to make sure it's safe to proceed with lumbar puncture. And so, we would recommend the lumbar puncture in the left lateral decubitus position and allowing the patient to be as calm and relaxed as possible to be able to get that accurate opening pressure. Once we get that, we can send the CSF for contents, looking for- making sure they don't have any signs of meningitis or raised protein. And then, really, we're at that point of saying, you know, we should have a secure diagnosis, whether it would be a structural lesion, venous sinus thrombosis, or idiopathic intracranial hypertension. Dr Nevel: Wonderful. Thank you for that really nice overview and, kind of, diagnostic pathway and stepwise thought process in the evaluations that we do. There are several different treatments for papilledema that you go through in your article, ranging from surgical to medication options. When we're taking care of an individual patient, what factors do you use to help guide you in this decision-making process of what treatment is best for the patient and how urgent treatment is? Dr Mollan: I think that's a really important question because there's two things to consider here. One is, what is the underlying diagnosis? Which, hopefully, through the investigational save, you'll have been able to achieve a secure diagnosis. But going along that investigational pathway, which determines the urgency of treatment, is, what's happening with the vision? If we have somebody where we're noting that the vision is affected- and normally it's actually through a formal visual field. And that's really challenging for lots of people to get in the emergency situation because syndromes of raised endocranial pressure often don't cause problems with the visual acuity or the color vision until it's very late. And also, you won't necessarily get a relative afferent papillary defect because often it's bilateral. So I really worry if any of those signs are there in somebody that may have papilledema. And so, a lot rests on that visual field. Now, we're quite good at doing confrontational visual fields, but I would say that most neurologists should be carrying pins to be able to look at the visual fields rather than just pointing fingers and quadrants if you're not able to get a formal visual field early. It's from that I would then determine if the vision is affected, I need to step up what I'm going to do. So, I think the sort of next thing to think about is that sort of vision. So, if we have somebody who, you know, you define as have severe sight loss at the point that you're going through this investigational pathway, you need to get an ophthalmologist or a neuro-ophthalmologist on board to help discuss either the surgery teams as to whether you need to be heading towards an intervention. And there are a number of different types of intervention. And the reason why we discuss it in the article---and we'll also be discussing it in a future issue of Continuum---is there's not high-class evidence to suggest one surgery over another surgery. We may touch on this later. So, we've got our patients with severe visual loss who we need to do something immediately. We may have people where the papilledema is moderate, but the vision isn't particularly affected. They may just have an enlarged blind spot. For those patients, I think we definitely need to be thinking about medical therapy and talking to them about what the underlying cause is. And the commonest medicine to use for raised endocranial pressure in this setting is acetazolamide, a carbonic anhydrous inhibitor. And I think that should be started at the point that you believe somebody has moderate papilledema, with a lot of discussion around the side effects of the medicine that we go into the article and also the fact that a lot of our patients find acetazolamide in an escalating dose challenging. There are some patients with very mild papilledema and no visual change where I might say, hey, I don't think we need to start treatment immediately, but you need to see somebody who understands your disease to talk to you about what's going on. And generally, I would try and get somebody out of the emergency investigational pathway and into a formal clinic as soon as possible. Dr Nevel: Thank you so much for that. One thing that I was wondering that we see clinically is you get a consult for a patient, maybe, who had an isolated episode of vertigo, back to their normal self, completely resolved… but incidentally, somebody ordered an MRI. And that MRI, in the report, it says partially empty sella, slight flattening of the posterior globe, concerns for increased intracranial pressure. What should we be doing with these patients who, you know, normal neurological exam, maybe we can't detect any definite papilledema on our endoscopic exam. What do you think the appropriate pathway is for those patients? Dr Mollan: I think it's really important. The more neuroimaging that we're doing, we're sort of seeing more people with signs that are we don't believe are normal. So, you've mentioned a few, the sort of partially empty sella, empty sella, tortuosity of the optic nerves, flattening of the globes, changes in transverse sinus. And we have quite a nice, again, table in the article that talks about these signs. But they have really low sensitivity for a diagnosis of raised endocranial pressure and isolation. And so, I think it's about understanding the context of which the neuroimaging has been taken, taking a history and going back and visiting that to make sure that they don't have escalating headache. And also, as you said, rechecking the eye nerves to make sure there's no papilledema. I think if you have a good examination with the direct ophthalmoscope and you determine that there's no papilledema, I would be confident to say there's no papilledema. So, I don't think they need to necessarily cry doubt. The ophthalmology offices, we certainly are having quite a few additional referrals, particularly for this, which we kind of called IIH-RAD, where patients are coming to us for this exclusion. And I think, in the intervening time, patients can get very anxious about having a sort of MRI artifact picked up that may necessarily mean a different diagnosis. So, I guess it's a little bit about reassurance, making sure we've taken the appropriate history and performed the examination. And then knowing that actually it's really a number of different signs that you need to be able to confidently diagnose raised ICP, and also the understanding that sometimes when people have these signs, if the ICP reduces, those signs remain. You know, we're learning an awful lot more about MRI imaging and what's normal, what's within normal limits. So, I think reassurance and sensible medical approach. Dr Nevel: Absolutely. In the section in your article on idiopathic intracranial hypertension, you spend a little bit of time talking about how important it is that we sensitively approach the topic of potential weight loss for those patients who are overweight. How do you approach that discussion in your clinic? Because I think it's an important part of the holistic patient care with that condition. Dr Mollan: I think this is one of the things that we've really listened to the patients about over the last number of years where we recognize that in an emergency situation, sometimes we can be quite quick to sort of say, hey, you have idiopathic endocranial hypertension and weight loss is, you know, the best treatment for the condition. And I think in those circumstances, it can be quite distressing to the patient because they feel that there's a lot of stigma attached around weight management. So, we worked with the patient group here at IIH UK to really come up with a way of a signposting to our patients that we have to be honest that there is a link, you know, a strong evidence that weight gain and body shape change can cause someone to fall into a diagnosis of IIH. And we know that weight loss is really effective with this condition. So, I think where I've learned from the patients is trying to use language that's less stigmatizing. I definitely signpost that I'm going to talk about something sensitive. So, I say I'm going to talk about something sensitive and I'm going to say, do you know that this condition is related to body shape change? And I know that if I listen to this podcast in a couple of years, I'm sure my words will have changed. And I think that's part of the process, is learning how to speak to people in an ever-changing language. And they think that sort of signpost that you're going to talk about something sensitive and you're going to talk about body shape change. And then follow up with, are you OK with me talking about this now? Is it something you want to talk about? And the vast majority of people say, yes, let's talk about it. There'll be a few people that don't want to talk about it. And I usually come in quite quickly, say, is it OK if I mention it at the next consultation? Because we have a duty of care to sort of inform our patients, but at the same time we need to take them on that journey to get them back to health, and they need to be really enlisted in that process. Dr Nevel: Yeah, I really appreciate that. These can be really difficult conversations and uncomfortable conversations to have that are really important. And you're right, we have a duty as medical providers to have these conversations or inform our patients, but the way that we approach it can really impact the way patients perceive not only their diagnosis, but the relationship that we have with our patients. And we always want that to be a positive relationship moving forward so that we can best serve our patients. Dr Mollan: I think the other thing as well is making sure that you've got good signposts to the professionals. And that's what I say, because people then say to me, well, you know, kind of what diet should I be on? What should I be doing? And I say, well, actually, I don't have professional experience with that. I'm, I'm very fortunate in my hospital, I'm able to send patients to the endocrine weight management service. I'm also able to send patients to the dietetic service. So, it's finding, really, what suits the patient. Also what's within licensing in your healthcare system to be able to provide. But not being too prescriptive, because when you spend time with weight management professionals, they'll tell you lots of different things about diets that people have championed and actually, in randomized controlled trials, they haven't been effective. I think it's that signpost really. Dr Nevel: Yeah, absolutely. So, could you talk a little bit about what's going on in research in papilledema or in this area, and what do you think is up-and-coming? Dr Mollan: I think there's so much going on. Mainly there's two parts of it. One is image analysis, and we've had some really fantastic work out of the Singapore group Bonsai looking at a machine learning decision support tool. When people take fundal pictures from a normal fundus camera, they're able to say with good certainty, is this papilledema, is this not papilledema? But more importantly, if you talk to the investigators, something that we can't tell when we look in is they're able to, with quite a high level of certainty, say, well, this is base occupying lesion, this is a venous sinus thrombosis, and this is IIH. And you know, I've looked at thousands and thousands of people's eyes and that I can't tell why that is. So, I think the area of research that is most exciting, that will help us all, is this idea about decision support tools. Where, in your emergency pathway, you're putting a fundal camera in that helps you be able to run the image, the retina, and also to try and work out possibly what's going on. I think that's where the future will go. I think we've got many sort of regulatory steps and validation and appropriate location of a learning to go on in that area. So, that's one side of the imaging. I think the other side that I'm really excited about, particularly with some of the work that we've been doing in Birmingham, is about treatment. The surgical treatments, as I talked about earlier… really, there's no high-class evidence. There's a number of different groups that have been trying to do randomized trials, looking at stenting versus shunting. They're so difficult to recruit to in terms of trials. And so, looking at other treatments that can reduce intracranial pressure. We published a small phase two study looking at exenatide, which is a glucagon-like peptide receptor agonist, and it showed in a small group of patients living with IIH that it could reduce the intracranial pressure two and a half hours, twenty-four hours, and also out to three months. And the reason why this is exciting is we would have a really good acute therapy---if it's proven in Phase III trials---for other diseases, so, traumatic brain injury where you have problems controlling ICP. And to be able to do that medically would be a huge breakthrough, I think, for patient care. Dr Nevel: Yeah, really exciting. Looking forward to seeing what comes in the future then. Wonderful.

In this powerful and heartfelt episode of Innovate & Elevate, Sharon Kedar is joined by two remarkable young women, Alice Paul Tapper and Audrey Maged, for an inspiring discussion on the importance of self-advocacy and resilience, particularly in the face of medical misdiagnosis.Alice, a high school senior and author of two picture books, including her upcoming release "Use Your Voice," shares her harrowing experience of surviving untreated appendicitis that led to a life-threatening sepsis diagnosis. She details her journey from feeling dismissed by healthcare professionals to becoming a fierce advocate for herself and others. Her story is a testament to the critical need for patients, especially young girls, to speak up and advocate for their own health, even when it means challenging authority.Audrey Maged, Sharon's daughter and a fourth grade student, was diagnosed with pseudotumor cerebri, more commonly known as idiopathic intracranial hypertension (IIH), a condition that involves increased pressure around the brain, leading to symptoms like severe headaches. Audrey joins the conversation to reflect on the common barriers children face when trying to express their needs in a healthcare setting. Both Alice and Audrey emphasize the importance of teaching young people to use their voices, not just in healthcare but in all areas of life.Sharon, Alice, and Audrey unpack the societal norms that often discourage girls from being assertive and how these norms can have serious consequences when it comes to healthcare. They also discuss the emotional and psychological impacts of feeling unheard and the role parents and communities play in empowering children to advocate for themselves.Episode Outline(01:47) Raise Your Hand: Be Bold, Be Brave (09:42) Alice's Misdiagnosis Journey (18:45) Use Your Voice: You Are Your Best AdvocateConnect with SharonConnect with Sharon on LinkedIn: Sharon KedarFollow Sharon on Instagram: @sharonkedarcfa Learn more about Innovate and Elevate innovateandelevatepodcast.comSubscribe to Innovate and Elevate on YouTubeJoin the newsletter to receive the latest episodes in your inbox: Innovate and Elevate NewsletterAdditional ResourcesUse Your Voice by Alice Paul Tapper Raise Your Hand by Alice Paul Tapper Raise Your Hand Girl Scout PatchChildren's Hospital of Philadelphia This podcast is produced by the women at The Wave Editing

Podcast: This week on the show, we present a pre-recorded conversation with Rawn Clark, author of A Bardon Companion: A Practical Companion for the Student of Franz Bardon's System of Hermetic Initiation. The Franz Bardon series of books on Magical Arts, Initiation into Hermetics (IIH), The Practice of Magical Evocation (PME), and The Key to the True Qabalah (KTQ), are considered by many as the most lucid and actionable written material on Hermetic practice. Initiation into Hermetics consists of a short introduction on theory and ten detailed lessons on practice covering work on the Mental, Astral, and Physical bodies. These lessons progress from very basic mental concentration and thought control practices through to advanced exploration of elemental and planetary realms and the merging with Unity. In A Bardon Companion, Rawn Clark combines two versions of his commentaries for each of the ten steps in IIH, additional commentaries on PME and KTQ, as well as years of correspondence with students of the Bardon system. It is an essential guide for anyone interested in exploring the Bardon system of Hermetics. Rawn Clark is a writer and video producer who dedicates his work to magical practice in general and providing support material for practitioners of the Bardon system. He began pursuing Bardon's system of Hermetic Initiation in the early 1980s at the age of 25. Years later he became involved in online blogging and discussion groups surrounding the Bardon work. He has emerged as one of the leading mentors for this system. His writings are clear, practical, and leavened with a gentle touch and humor. His work dispels many of the misconceptions associated with esoteric practice and makes the Bardon system available to anyone willing to put in the necessary consistent effort.

This week's episode is with Levi Peterson, a fighter of Idiopathic Intracranial Hypertension, Neuro-Behçet's syndrome, and Parksinon's disease. Levi has also experienced 10 major brain surgeries, resulting in her becoming an expert on shunting technology from past complications. In the past, she was an EMT, and currently, she is a patient navigator, which we expand on in the episode.In addition, Levi shares ways she maintained hope and remained strong through her 10 brain surgeries and how she is using her experiences to help other patients currently. We also talk about the numerous complications Levi endured after her invasive surgeries and how artificial intelligence could play a role in the future of shunts. We later discuss the stigma behind IIH and how new research and technology are playing a role in reducing this stigma and increasing awareness of rare neurological disorders. Levi's bravery and strength are incredible, and her humor makes this episode an entertaining listen! Make sure to subscribe to the Neurological Disorder Podcast on Spotify, Apple Podcasts, or wherever you listen to your podcasts! Follow me on Instagram- @neurologicaldisorderpodcast Email me - neurologicaldisorderpodcast@gmail.comLinks Levi Mentioned/helpful resources:https://rarediseases.org/https://my.clevelandclinic.org/health/diseases/21968-idiopathic-intracranial-hypertensionhttps://www.mayoclinic.org/diseases-conditions/behcets-disease/symptoms-causes/syc-20351326

GB2RS News Sunday the 15th of October 2023 The news headlines: • RSGB Construction Competition • New chair of the RSGB's Exams and Syllabus Group • RSGB 2023 Convention The RSGB recognises the importance of construction as a key element of amateur radio, whether that is using traditional construction skills or is a software or systems engineering project. The Society has launched its 2024 Construction Competition and the deadline for entries is the 1st of March 2024. To enable members across the country, and even the world, to enter, entries will be judged over the internet rather than in person. This year a new category called ‘Antennas' has been introduced so there are five categories you can enter: Beginners; Construction Excellence; Innovation; Software and Systems; and Antennas. Special recognition will be given to entries submitted by radio amateurs under the age of 24, and to those who have just gained their Foundation licence. A cash prize will be awarded for the winner of each section, with a bonus for the overall winner, who will also be declared the winner of the Pat Hawker G3VA Award. You can find out more, including how to enter, on the RSGB website at rsgb.org/construction-competition The RSGB is delighted to welcome Andrew Lenton, G8UUG as the new Chair of the Exams and Syllabus Review Group. The Society would also like to thank Donard de Cogan, M0KRK for his hard work and dedication, including chairing the Group for the past three years. You can contact Andrew via esrg.chair@rsgb.org.uk The RSGB 2023 Convention takes place over both days this weekend. There is a fantastic range of presentations on a variety of amateur radio topics. If you haven't already booked, you can buy day tickets on the door or join the Livestream at any time over the weekend. The Livestream contains 12 of the Convention presentations as well as exclusive interviews and additional content. We are asking radio amateurs to register for the Convention Livestream this year. Whether you are there in person, or joining radio amateurs from across the world online, make sure you are part of this major annual event. For more information about the full programme of presentations go to rsgb.org/convention and to register for the Livestream head over to rsgb.org/livestream As we get closer to the ITU World Radio Conference, WRC-23, which starts next month, the future of amateur radio, particularly the 23cm band, is of key importance. The ITU News Magazine has a feature article by IARU President Tim Ellam, VE6SH regarding amateur activity in the 23cm band. This is the topic of a challenging agenda item at the Conference which calls for measures that protect primary radio-navigation services such as Glonass and Galileo from amateur terrestrial and satellite usage. You can read the article by visiting tinyurl.com/TimVE6SH In related news, the IARU also reports that the last formal preparatory meeting ahead of the WRC on this topic was difficult and could not achieve a consensus on measures such as power and bandwidth limits, or frequency restrictions. The IARU supports further efforts and will continue to try to find a solution regarding suitable recommendations, whilst opposing the unwarranted statutory imposition of such. You can read the IARU's post on this subject via tinyurl.com/ITUR23cm  Also, you can hear the latest updates at the RSGB Convention on Sunday, in a talk by IARU expert and RSGB Microwave Manager Barry Lewis, G4SJH.  Jamboree On The Air, or JOTA, is an annual event in which Scouts and Guides all over the world communicate with each other via amateur radio.

Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. German stations also send their DOK reference. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 12th of October 2023 We had a period of low geomagnetic disturbance last week, which allowed the upper HF bands to shine. There were lots of reports of DX being worked on the 10m band as the Kp Index sat mainly in the ones and twos, with a maximum of Kp 3.33 for one three-hour period on the 9th. The Solar Flux Index, or SFI, also remained in the 150s and 160s, hitting a maximum of 166 on the 9th. All in all, these were very good conditions for high-band DXing, especially at this optimum time in the calendar. As promised last week, let's take a look at HF paths from the UK to the W8S Swains Island DXpedition in the South Pacific. The good news is that operations are in full swing and are being spotted daily on the DX Cluster. At a distance of approximately 9,500 miles from the UK on the short-path, and 15,300 miles on the long-path, it's quite a distance for signals to traverse. The short-path beam heading you need to select is a polar path at 350 degrees, and for long-path 169 degrees. The best openings to Swains from the UK start on the 20m band from about 0630UTC. As the morning progresses, move up in frequency until you get to the 10m band around 1000 to 1100UTC. This path should remain open until 1500 or 1600UTC, at which point you can drop down to the 12, 15 or 17m bands. Long-path openings may be a lot weaker, with a short opening on the 15m band from 0600 to 0800UTC. Then move to the 12 or 10m bands from 0700 to 0900UTC. There may also be a long-path evening opening from 1800 to 2000UTC on the 17 and 10m bands. The above predictions are for SSB and CW. You may find FT8 openings extend these times a little. For more details, and to compute your own predictions, see VOACAP.com or Proppy at soundbytes.asia/proppy This weekend, ending today the 15th, may see some geomagnetic disturbances due in part to a coronal hole. But, as long as we don't get any coronal mass ejections, this should settle after the weekend.  The Solar Flux Index is predicted to remain in the 150s with a maximum Kp index of two. If this turns out to be true, we should have a good week of DX hunting to come. And now the VHF and up propagation news The coming period of weather offers many changes, and it looks as though we have said goodbye to the warm air, with low pressure controlling events.   Just a gentle reminder to keep an eye on your antennas as this time of year can produce surprisingly rapid developments of deep low-pressure systems with associated strong winds.  Early next week, a temporary high returns to give you a chance to give those antenna supports and guys a once-over while winds are light, and leave the potential Tropo until the evenings and overnight. Incidentally, this new high is essentially a cold air high, so may not be as productive as the recent Tropo of the week just ending. The new high will probably hang around until midweek when it should migrate north to allow an easterly wind across the south. This will probably bring some showery rain along the east coast. It's possible that we may have some rain scatter from these showers. Meteor scatter is always good in October, with high random meteor rates and a number of small showers. Most notable of these is the Orionids Meteor Shower which peaks on the 22nd of October and is active until the 7th of November with an average zenithal hourly rate of around 20. Of course, aurora is also worth keeping in mind if you get any spare time! For EME operators, Moon declination is negative and falling all week, reaching minimum on Friday the 20th with corresponding shortening Moon windows. As we are now past apogee, path losses will continue to fall.  144MHz sky noise starts very high with the annular eclipse on Saturday the 14th. The following week sees it moderate, increasing to a high of over 2000 Kelvin on Thursday. And that's all from the propagation team this week.

Modelling idiopathic intracranial hypertension in rats: contributions of high fat diet and testosterone to intracranial pressure and cerebrospinal fluid production

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.01.31.526446v1?rss=1 Authors: Wardman, J. H., Jensen, M. N., Andreassen, S. N., Styrishave, B., Wilhjelm, J. E., Sinclair, A. J., MacAulay, N. J. Abstract: Background: Idiopathic intracranial hypertension (IIH) is a condition characterized by increased intracranial pressure (ICP), impaired vision, and headache. Most cases of IIH occur in obese women of childbearing age, though age, BMI, and female sex do not encompass all aspects of IIH pathophysiology. Systemic metabolic dysregulation has been identified in IIH with a profile of androgen excess. However, the mechanistic coupling between obesity/hormonal perturbations and cerebrospinal fluid dynamics remains unresolved. Methods: Female Wistar rats were either fed a high fat diet (HFD) or exposed to adjuvant testosterone treatment to recapitulate IIH causal drivers. Cerebrospinal fluid (CSF) and blood testosterone levels were determined with mass spectrometry, ICP and CSF dynamics with in vivo experimentation, and the choroid plexus function revealed with transcriptomics and ex vivo isotope-based flux assays. Results: HFD-fed rats presented with increased ICP, which was not accompanied by altered CSF dynamics or modified choroid plexus function. Chronic adjuvant testosterone treatment of lean rats caused elevated CSF secretion rate, in association with increased activity of the choroid plexus Na+,K+,2Cl- cotransporter, NKCC1. Conclusions: HFD-induced ICP elevation in experimental rats did not originate from an increased rate of CSF secretion. Such modulation of CSF dynamics only came about with adjuvant testosterone treatment, mimicking the androgen excess observed in female IIH patients. Obesity-induced androgen dysregulation may thus play a crucial role in the disease mechanism of IIH. Copy rights belong to original authors.

Thank you for joining us for our 2nd Cabral HouseCall of the weekend! I'm looking forward to sharing with you some of our community's questions that have come in over the past few weeks… Tennea: Hi Dr Cabral, I'm currently doing your IHP training. I wanted to know if you have any advice on the condition called Chronic Regional Pain Syndrome (CRPS) I had an accident 4 years ago leaving me “permanently disabled” in my left arm, hand, and shoulder after breaking my elbow (terrible triad). And I ended up with this nerve chronic pain CRPS. I also developed a anaphylactic reaction to seafood last year (I LOVE seafood), I believe it's related to the CRPS. I would be eternally great full for your advice or thoughts on this. Warm regards Teena Lara: Hi, dr. Cabral :) I'm hoping you could talk about the “extra” ingredients in supplements.. like different fillers, additives, preservatives..? Which ones should we be careful about, which different names do they use for the same crappy substance, for example, citric acid is in lots of them, also lactic acid, etc. What kind of a capsule (vegan) should it be and so on? Would love to buy extra clean supplements but sometimes it's really difficult to get them, especially with the crazy prices.. Thank you! Happy healing, everyone!   Rachel: Body odour. I sometimes find that I have very very strong body odour in my armpits. It's not the "normal" BO smell. It is pungent but more like a strong gasoline smell. When it happens it's almost as if I can't wash it off. Showering and washing my armpits helps lessen it, but the smell is still there. Any idea what the cause could be or how to rectify it? Thank you! Debra: I have mast cell disease,, hereditary alpha tryptaemia syndrome, and Intracranaian increased hypertension which causes debilitating migraines. I have done your detox and despite the debilitating migraines getting worse I stuck it out. I did the hair migraine erase test and I had to stop all supplements recommended for now. I was reacting to everything. Especially the shakes high in vitamin A. Do you have experience in IIH aka pseudo tumor? Would love to work together further. I'm a huge fan and desperate to heal.thanks, Debra Nick: Hi Dr. Cabral! I have two questions for you — one, i recently had a snowboarding accident where i hit my head and got a CT scan and MRI which showed a Cavernoma in the back upper outer edge of my head. Do you have any natural remedies advice for controlling / improving it? i've had no symptoms and it was found incidentally. (i'm 25 years old) my second question is — they told me i will need to monitor it probably 1-2 times a year with contrast and no contrast MRI. Should i be concerned with the gadolinium metal that's used to contrast the MRI? if so, would you have any alternative suggestions (i.e. recommending no contrast) or any detox solutions you'd recommend if you think it's necessary? thank you!

Thank you for joining us for our 2nd Cabral HouseCall of the weekend! I'm looking forward to sharing with you some of our community's questions that have come in over the past few weeks… Let's get started!    Simon: Hi Dr Cabral, I am looking to improve my immune defenses against a 'certain virus' and am concerned that my white blood cell count is sub-optimal (4,000/ul) despite my otherwise good health. I suspect this may be a hangover from having VERY low WBC levels after contracting dengue fever 5 years ago. Is increasing my WBC something I should be exploring and what can I do to get my count up?   Lorena: Thank you so much for all you do for your community! Not sure if you remember but I asked here a few weeks ago regarding my elevated heart rate at night according to my Oura ring and that I started to experience a lot of neurological symptoms (similar to MCAS) such as anxiety, heart palpitations and pseudoseizures at the same time. You mentioned that I should check my cortisol levels at night (which I did and was slightly elevated in the PM and low in the AM). I'm a Vata level 1 and 2 IHP so I literally ran all of the labs that you can imagine as I was very confused as to what was going on. Hormones, heavy metals, stool, OAT, neurotransmitters + more. Everything was fine except some candida/mould overgrowth as well as elevated toxic metals. I started the CBO again (last one was over a year ago) + heavy metal detox + 21 day detox all at the same time lol. Anyways, I haven't felt any neurological symptoms after just a couple of days of starting these protocols. I can't figure out how this would have happened. Surely 2 days worth of protocols is not enough to stop these symptoms (very happy though). Any idea why?   Lorena: Hi Doc, me again! I forgot to mention that I also ran a precision allergy test by Precision Point Diagnostics because they test IgE, IgG, IgG4 and complement (C3d) from blood serum. It's much more expensive so not very affordable for a lot of people. Anyways, a lot of things came up and I also eliminated the ones in the red section of my IgE and IgG (vanilla, banana & more) at the same time that I started all the protocols. A lot of them showed in the IgE section and these were foods that I was consuming on a daily basis when I was having all of those symptoms. Do you think it might have been the removal of these foods that caused the relief of symptoms so quickly? If so, it's crazy how consuming foods you're sensitive to from an IgE and IgG perspective can do to you! I always thought this wasn't a big deal but it clearly is.    Nina: Hi doctor Cabral, I get very lightheaded every time I bend down to pick up something. Do you know why this is happening? I do have a low blood pressure, so maybe that could have something to do with it, but I really want to know if there's anything else that could be causing it. I also always feel cold, especially in my extremities. Just to give you some background, I'm a 44 year old female, no kids, vegan and pretty active. Thanks so much for your answer, I really appreciate your help! Nina   Farrel: Hello, Dr Cabral. I trust you and your family are in great health. Listening to older episodes and about two years ago on a House call segment you were asked about Tongkat Ali and it's use for athletes and men in their 30's. You went on to say there's a product your team will be launching around September 2020 called Libido Booster. I purchase from the site and I've never seen it. Has the launch been put on hold or it won't be released? Keep up great work.   Andjela: Hello Dr!! Thanks for your information! Love following you on Instagram. I had covid (delta) in October 2021, and now 3 months later experiencing hair loss. So are many of my relatives who all had it at the same time. Any suggestions on remedies?   Danielle: Hello Dr. Cabral,Thank you so much for sharing your knowledge in functional medicine. I've read your book twice and have no doubt I'll read it again. I listen to this podcast daily and am awaiting the arrival of the minerals and metals test. My question is related to IIH. (I understand the medical advice disclaimer) Are there any natural ways to reduce pressure in the head? I do not want a LP. How else can I reduce excess fluid? I do take L-Lysine and well as a long list of other supplements daily. I'm also taking Goduchi and Triphala as herbal support and am on 2 pharmaceuticals as well, which Id love to come off of, safely, of course. Thanks so much for your time.

Venous sinus stenting (VSS) is a safe, effective, and increasingly popular treatment option for selected patients with idiopathic intracranial hypertension (IIH). Serious complications associated with VSS are rarely reported. In this podcast, JNIS Editor-in-Chief, Felipe C. Albuquerque, interviews Dr. Kyle Fargen, from the Department of Neurosurgery, Wake Forest University, Winston-Salem, North Carolina, about a case series in which serious complications after VSS were identified retrospectively from multicenter databases.

Do you find yourself getting angry more frequently? Crying more or sometimes feel like you have a rogue persona inside of you that takes control and sends you into worry tail spins or eating binges? My guest on this episode is Rene Brent, RN and Certified Clinical Hypnotherapist/Instructor. Today Rene shares a quick, and I mean quick, exercise you can do to calm your mind and your nervous system plus she shares her favorite phrase for shifting that rogue persona from control to the backseat. Rene and I discuss how to give yourself permission to change your behavior that no longer serves you and a few questions you can ask yourself to gain awareness of patterns that build worry and increase your use of the but. Rene Brent has been a RN for 30 years and has worked in ICU, Trauma/ER and the Recovery Room. In her experience, she was inspired by the powerful mind/body connection and how self-awareness and reframing negative thoughts helps us heal emotionally and physically. It was a natural transition for Rene Brent to go from being a healer of the body to a healer of the mind. She is passionate about helping her clients use the power of the mind and move forward in their lives and reach personal and professional goals. Rene attended The Institute of Interpersonal Hypnotherapy (IIH in Tampa, Fl.) IIH is the only state licensed school of Hypnotherapy in Florida. Rene has trained over 1000 hours.

Today I will be discussing the mental section of Step Five. I think for the modern reader especially, this is perhaps the most enigmatic section in the whole of IIH. But with just a few essential bits of additional information it begins to reveal its meaning. --- Support this podcast: https://anchor.fm/MysticalThoughts/support

Mystical Thoughts: A dive into Occult thought and practice

I have chosen this title, “Simple Beginnings”, to emphasize that Step One is just the beginning and that it is simple. All too often a new student of initiation will read the Step One exercises and think that they are very complex and that completing them requires already advanced abilities, or that performing the exercises will require so much time each day that they will have no time left over for anything else, such as making a living and entertaining their friends, etc., etc., etc.. None of these assumptions are accurate. According to his own words, Bardon arranged IIH as if it was “meant for the busiest man”, and even though Bardon's way of phrasing things may seem somewhat archaic and oftentimes confusing to a modern reader, the exercises he is describing in Step One are rudimentary and the essence of simplicity, designed with the absolute beginner in mind. Furthermore, according to Bardon's own instructions, they are each to be completed relatively quickly, within one to two weeks in most cases. --- Support this podcast: https://anchor.fm/MysticalThoughts/support

Interview mit Andreas Weinhart zum Thema Fußekel IIIIIiiiiiihhhhhh Füße – auch das hören wir oft, wenn wir barfuß unterwegs sind, oder auch in der Community wenn ihr damit konfrontiert werdet. Total spannend, wie unterschiedlich das sein kann. Mal ist der Fuß ein Objekt der Begierde und dann wird er wiederum als Fremdkörper angesehen. Andreas Weinhardt kennt das selbst auch, er ist berufsbedingt oft in Situationen, wo er fremder Menschen Füße sieht oder auch anfassen muss. Als Pfleger hat er da auch nicht immer die hübschesten Füße vor Augen. Das löste allerdings nicht seinen EKEL vor Füßen aus – wir vermuten zusammen, dass es in der Kindheit oder Jugend Situationen gegeben hat, die das versucht haben. Er ist allerdings kein Fußphobiker, also Menschen die dann sogar Panikattacken und Angstzustände bekommen, sondern bekämpft schon seit langem seinen Ekel. Er pflegt seine eigenen Füße und beschäftigt sich mit dem Barfußgehen, um einen anderen Blickwinkel zu bekommen. Wir entdecken immer wieder, dass der Umgang der Eltern eine große Rolle spielt. Aus „Spaß“ zu sagen „Iih, Stinkefüße“ oder auch das während der Pflege der Füße nicht gut über diese gesprochen wird. Aber löst das tatsächlich den Ekel aus oder sogar eine Phobie?

In this episode of the Epigenetics Podcast, we caught up with Dr. Danny Reinberg from the New York University School of Medicine to talk about his work on transcription and polycomb in inheritance and disease. Dr. Danny Reinberg is a pioneer in the characterization of transcription factors for human RNA polymerase II. In his groundbreaking work in the 1990s, he purified the essential transcription factors and reconstituted the polymerase in vitro on both naked DNA and chromatin.  Dr. Reinberg next started focusing on the polycomb repressive complex 2 (PRC2), which is the only known methyltransferase for lysine 27 on histone H3. He biochemically characterized the PRC2 subunits EZH1 and EZH2. More recently, Dr. Reinberg has been investigating the role of PRC2 in neurons.  This interview discusses the story behind how Dr. Danny Reinberg started his research career by identifying the essential RNA polymerase transcription factors, how he discovered and characterized the polycomb repressive complex 2 (PRC2), and what his research holds for the future.   References H.

Episode 25 - Evaluation and Management of Life-Threatening Headaches in the Emergency Department

EMplify by EB Medicine

Shownotes Jeff: Welcome back to EMplify, the podcast corollary to EB Medicine’s Emergency Medicine Practice. I’m Jeff Nusbaum, and I’m back with my co-host, Nachi Gupta. This month, we’re tackling an incredibly important topic - evaluation and management of life threatening headaches in the Emergency Department. Nachi: Fear not, this will not simply be “who needs a head CT episode”; we’ll cover much more than that. Listen closely as this is an important topic, with huge consequences for mismanagement. Jeff: Absolutely. As some quick background - headaches account for 3% of all ED visits in the US, with 90% being benign primary headaches and less than 10% being secondary to other causes like vascular, infectious, or traumatic etiologies. It’s within these later 10% that we are looking for the red flag signs to identify the potentially life-threatening headaches. Nachi: And to do so, Dr. David Zodda and Dr. Amit Gupta, PD and APD at Hackensack University Medical and Trauma Center, and their colleague Dr. Gabrielle Procopio, a PharmD, have done a fantastic job parsing through the literature, which included over 500 abstracts, 89 full text articles, guidelines from ACEP and the American Academy of Neurology, as well as canadian and european neurology guidelines, to summarize the best evidence based recommendations for you all. Jeff: We would be remiss to not also mention Dr. Mert Erogul of Maimonides Medical Center and Dr. Steven Godwin, Chair of Emergency Medicine at the University of Florida College of Medicine. Nachi: Alright, so let’s get started with some definitions and pathophysiology. The international classification of headache disorders 3, or ICHD-3, classifies headaches into primary, secondary, and cranial neuropathies. Jeff: Primary headache disorders include migraine, tension, and cluster headaches. Secondary headaches include those secondary to vascular disorders, traumatic disorders, and disorders in hemostasis. These are the potentially life threatening headaches that can have a mortality has high as 50%. Nachi: And the final category includes cranial neuropathies, such as trigeminal neuralgia. Jeff: And I think we can safely say that that wraps up our discussion in this episode on cranial neuropathies, moving on…. Nachi: Headaches result from traction to or irritation of the meninges and blood vessels, which are the only innervated central nervous system structures. Activation of specific nerve ganglion complexes by neuropeptides like -- substance P and calcitonin gene-related peptide -- are thought to contribute to head pain. Jeff: It is important to note that all headache pain shares common pain pathways, thus response to pain medications does not exclude potential life threatening secondary causes of headache. This led to the ACEP guideline which states just that.. Nachi: I feel like that deserves ding sound as it's a critically important point. To repeat, just because a pain medication relieves a headache, that does not exclude dangerous secondary causes! Jeff: And what are the life threatening headaches? Life-threatening headaches include subarachnoid hemorrhage, cervical Artery Dissection, which includes both vertebral Artery Dissection and carotid artery dissection, cerebral Venous Thrombosis, idiopathic intracranial hypertension, giant cell arteritis, and posterior reversible encephalopathy syndrome, or PRES. Nachi: Slow down for a second and let’s not skip over your favorite section.. Let’s talk pre hospital care for headache patients. Jeff: Good call! Pre-hospital care is fairly straightforward and includes a primary survey, conducting a focused neurologic exam, and assessing for red flag signs, which include focal neurologic deficits, sudden onset headache, new headache in those over 50, neck pain or stiffness, changes in visual Acuity, fever or immunocompromised State, history of malignancy, pregnancy or postpartum status, syncope, and seizure. That’s quite a list. For a visual reference, see Table 3 in the print issue. Nachi: And patients with neurologic deficits or severe sudden-onset headaches, should be transported immediately to the nearest available stroke center. Tylenol should be offered for pain management. Avoid opioids and nsaids. Jeff: Upon arrival to the emergency department, history and physical should include your standard vitals, testing neurologic function, cranial nerve testing, head and neck exam, as well as a fundoscopic exam. As was the case for your pre-hospital colleagues, you should also assess for red flag signs for life-threatening headaches. Check out tables 2, 3, and 4 for more details here. Nachi: With respect to Vital Signs, in the setting of an acute headache, severe hypertension should prompt a search for signs of end-organ damage such as hypertensive encephalopathy, intracranial Hemorrhage, PRES, and preeclampsia in pregnant women. Additionally, fever, and especially fever and neck stiffness, should raise concern for CNS infection. Jeff: For your neurologic examination, make sure to include assessments of motor strength, coordination, reflexes, sensory function, and gait. Don't forget that lesions involving the anterior circulation, such as dysarthria, cognitive impairment, and Horner syndrome may be indicative of a carotid artery dissection, whereas dizziness, vision changes, and limb weakness may be due to a vertebral Artery Dissection. Nachi: And for cranial nerve testing - pay particular attention to cranial nerves 2, 3 and 6. For cranial nerve 2 - look out for an afferent pupillary defect, or a marcus-gunn pupil, which is seen in optic neuritis, giant cell artertitis, and central retinal artery occlusion. For CN3, oculomotor nerve palsies raise concern for a posterior communicating aneurysm and SAH. And lastly, CN6 palsies, which often presents with diplopia on lateral gaze , are often seen with intracranial idiopathic hypertension and cerebral venous thrombosis, in addition to impaired visual acuity, visual field defects, and tunnel vision. Jeff: For the head and neck exam, remember that a partial horner syndrome, with miosis and ptosis without anhidrosis, may be indicative of a cervical artery dissection. Unfortunately, if the patient presents acutely, their only complaint may be pain, as the neurologic sequelae may take days to develop. Nachi: Additionally, with respect to the head and neck exam, evaluate the patient for tenderness and beading along the temporal artery. Jeff: One review noted that temporal artery beading actually had the highest likelihood ratio for GCA, 4.6, whereas temporal artery tenderness only had a LR of 2.6 Nachi: And the last physical exam maneuver you should ideally perform is a fundoscopic exam for papilledema, which is often seen in IIH, malignant hypertension, and CVT. Jeff: Perfect so that rounds out the physical, next we have diagnostic studies. Most importantly, routine lab testing is typically of low utility in aiding in the diagnosis of headache. Nachi: Even ESR and CRP in the setting of possible giant cell arteritis have poor sensitivity and specificity to diagnose it. So even if the ESR and CRP are negative, if the suspicion for GCA is high enough, it should be treated and you should get a biopsy. Jeff: Do consider adding on a venous or arterial carboxyhemoglobin in the right clinical scenario, as CO poisoning represents an important cause of headache you wouldn’t want to miss. This is especially important at this time of year when heating systems are working overtime here in the states. Nachi: And hopefully you have a co-oximeter, so you can even check this non-invasively. Jeff: Interestingly, there may be a unique role for a d-dimer here as well. Several small studies have used the d-dimer to risk stratify patients with possible CVT. In one study a d-dimer level < 500 mcg/L had a 97% sensitivity and a negative predictive value of 99% - not bad! Nachi: Pretty impressive performance characteristics. I think that about wraps up lab work. Let’s talk radiology. Jeff: Though low yield, CT utilization is estimated at 2.5-10% of non-traumatic headaches. A non-con CT should be reserved for those with suspicion for an intracranial hemorrhage, while a contrast CT would be required in those in whom there is concern for an infectious process or space occupying lesion. Nachi: CT angio or MRI should be used in cases of possible cervical artery dissection. MRI also is the neuroimaging of choice for PRES, which is more sensitive for cerebral edema than CT. Jeff: Similarly, MRV is recommended in those with a concerning story for CVT. Nachi: To help guide your emergent neuroimaging utilization, ACEP suggests imaging in those with headache and an abnormal finding on neuro exam, those with new and sudden-onset severe headache, HIV positive patients with new headache, and those over 50 with a new headache. Jeff: With that in mind, let’s dive a bit deeper into the use of CT for SAH, a topic which doesn’t get a ding sound, but is certainly critically important. Recent literature have found that a CT within 6 hours of symptom onset has a sensitivity and specificity and negative predictive value of 100%. In addition, one 2016 study demonstrated a LR of 0.01 in those with a negative HCT within 6 hours. These are really important results because that means SAH is essentially ruled out with a negative study. Nachi: Unfortunately, the 2008 ACEP guideline and 2012 AHA guidelines still recommend a lumbar puncture in those being worked up for SAH. Luckily the ACEP guideline is currently being revised so your decision to forego the LP with a negative HCT in the first 6 hours will likely also be backed by ACEP in the near future. Jeff: That’s a nice transition into our next test - the LP. Since LP carries a risk of herniation, in those with signs of increased ICP, make sure to get appropriate neuroimaging before attempting the puncture. In those without signs of increased ICP, no imaging is necessary. Nachi: While the position in which the LP is performed doesn’t matter as much when ruling out infection or SAH, in those with suspected IIH, make sure to obtain an opening pressure with the patient lying in the lateral decubitus position. An opening pressure of greater than 25 is often seen in IIH. Jeff: And the LP in the setting of IIH is not only diagnostic but also potentially therapeutic, as the removal of 1 ml of CSF can lower the pressure by 1 cm of H20 and potentially relieve the patient’s symptoms. Nachi: Always rewarding to diagnose and treat simultaneously... Jeff: Absolutely. But back to the LP for SAH for a second or two. When evaluating for a subarachnoid hemorrhage, you’ll often note an opening pressure of greater than 20 with persistent RBC in all tubes. Nachi: While there are no RBC cutoffs, one study found no patients with a SAH with less than 100 RBC in the final tube. In contrast, greater than 10,000 RBC increased the odds by a factor of 6. In addition, one 2015 study found that patients without xanthrochromia and less than 2000 RBC were effectively ruled out of having a SAH with a combined sensitivity of 100% Jeff: Lots of 100% sensitivities and specificities being thrown around today, which is definitely not the norm. No complaints here, I’ll take it. Anyway, the last test to discuss is our good friend the ultrasound, specifically the ocular ultrasound. Nachi: Examining the optic nerve sheath 3 mm posterior to the globe, an optic nerve sheath diameter of 5 mm or greater is predictive of an ICP greater than 20. Jeff: Keep in mind that this may expedite the work up, though a normal diameter does not rule out increased ICP, so a head CT may still be indicated. Nachi: Alright, so we’ve talked a lot about testing, both lab and imaging, and we’ve mentioned a bunch of pathologies, but let’s spend a few minutes going over the specifics of each. Jeff: Let’s start with SAH. SAH account for 1% of all headache visits to the ED. Most nontraumatic SAH are caused by aneurysm rupture. A missed diagnosis of SAH can have a case-fatality rate as high as 50% Nachi: Although 75% of SAH patients report an abrupt onset, objective neck stiffness has the highest likelihood ratio of 6.6. Other important features include LOC, neurologic deficit, subjective neck stiffness, photophobia, and onset during exertion or intercourse. Jeff: Additionally, approximately 20% of patients with a SAH have warning signs of a sentinel bleed including headaches, cranial nerve palsies, neck pain, or nausea and vomiting. Nachi: In order to aid you in diagnosing a SAH, you should consider the ottawa SAH Rule which has a 100% sensitivity and a 15% specificity. To use this rule you must be between 15 and 40 with a GCS of 15 and present with a headache with maximal intensity within 1 hour of onset. If you meet those inclusion criteria, and you have no neurologic deficits, no neck pain or stiffness, no witnessed LOC, no onset during exertion, no limitation of neck flexion, and no thunderclap onset, you can essentially rule out a SAH. Jeff: While the ottawa SAH rule has been prospectively validated, know that this study has been challenged for its interobserver variability, but in any case it still provides helpful red flags to consider. If your patient is found to have a SAH, a CT angiogram and neurosurgical consultation should be considered immediately. Nachi: In addition to monitoring ABCs, early care involves the administration of analgesics and anti-emetics. Also consider elevating the head of the bed to 30 deg, which may also improve venous drainage and decrease ICP. Jeff: In terms of BP management, guidelines from the american stroke association recommend targeting a SBP of 160 with a titratable agent like nicardipine or clevidipine. Nachi: In addition, nimodipine, 60 mg q4h, should be given to those with aneurysmal SAH to improve outcomes. Jeff: and any role for anti-epileptics? Nachi: That’s controversial and the authors state it may be considered in the immediate post-hemorrhagic period and should be limited to a 3-7 day course with longer courses required in special populations. Jeff: The next pathology to discuss is cervical artery dissections, which account for 2% of all strokes and nearly 20% of strokes in those 50 and under. cervical artery dissections are most commonly due to trauma, but can occur spontaneously. Nachi: Risk factors include Ehlers-Danlos syndrome, osteogenesis imperfecta, and Marfan syndrome. Jeff: Regardless of the etiology, the management of cervical artery dissections is primarily medical with IV heparin followed by warfarin or a direct oral anticoagulant in those with extracranial dissections, and antiplatelet therapy like aspirin or clopidogrel in those with intracranial dissections. Nachi: Thanks to the CADISP study, we know there is no difference in mortality or neurologic outcome when choosing between antiplatelet therapy and anticoagulation. Jeff: Next we have cerebral venous thrombosis. This typically presents with a gradual onset headache. Though it can happen to anybody, cerebral venous thrombosis typically results from thrombotic disease. Nachi: Important risk factors include oral contraceptive use, pregnancy and postpartum states, Factor V Leiden deficiency, and lupus. Jeff: Treatment for CVT is controversial due to a high risk of hemorrhage and hemorrhagic transformation. According to the best available evidence, anticoagulation is the standard therapy with full dose anticoagulation of low-molecular weight heparin or heparin as a bridge to warfarin. Nachi: Yeah, it’s really a tough spot to be in as one third end up having some form of hemorrhage too…. Jeff: Perhaps yet another good place for shared decision making? Nachi: Honestly, it’s a good thought, but anticoagulation is the guideline recommendation, so I think that is likely the best route in this case. Jeff: Great point. Next we have idiopathic intracranial hypertension. This is typically associated with obese women of childbearing age. It may also be due to hypervitaminosis A from excessive dietary intake and even drugs like the retinoids used in treating dermatologic conditions and cancers. Nachi: idiopathic intracranial hypertension can be diagnosed by the modified dandy criteria which are found in table 8 on page 11. Let’s just run through the criteria. Jeff: The modified Dandy criteria for idiopathic intracranial hypertension include: signs and symptoms of increased ICP, no other neurologic abnormalities or altered level of consciousness, ICP > 20 on LP with normal CSF composition, neuroimaging without another etiology for intracranial hypertension, and lastly no other identified cause of intracranial hypertension. Nachi: And as we mentioned a few minutes ago, an LP can be both diagnostic and therapeutic, though the relief is likely temporary Jeff: For more permanent treatment, weight loss is the key. Acetazolamide, 250 mg to 500 BID is the first line pharmacotherapy. Combined with weight loss, acetazolamide and a low sodium diet has been shown to improve visual field function. Nachi: And if this fails, topiramate, furosemide, and in the worst case surgical options like CSF shunting, venous sinus stenting, and optic sheath fenestration are all options. Jeff: I imagine taking a diuretic for a headache could be a real hindrance on quality of life, though I suppose it’s better than risking vision loss or having a significant neurosurgery. Nachi: Agreed. Next we have giant cell arteritis. GCA is rare, with a prevalence of

Gene transcription is a fundamental process of the living cell. Eukaryotic transcription of messenger RNA requires the regulated recruitment of the conserved transcribing enzyme RNA polymerase (Pol) II to the gene promoter. The most heavily regulated step is transcription initiation that involves the ordered assembly of Pol II, the general transcription factors (TF) -IIA, -IIB, -IID, -IIF, -IIE, -IIH and the co-activator Mediator complex. Mediator communicates between transcription regulators and Pol II, and is associated with human disease. Mediator from the yeast Saccharomyces cerevisiae (Sc) has a molecular mass of 1.4 megadaltons and contains 25-subunits that constitute a head, middle, tail and kinase module. The core of Mediator contains the head and middle modules that are essential for viability in Sc, and directly contact Pol II. Mediator co-operates with TFIIH, to assist assembly and stabilization of the transcription initiation complex and stimulate TFIIH kinase activity. Because of the large size and complexity of Mediator and the initiation machinery, the underlying mechanism remains poorly understood. In this work we studied the structure and function of Mediator head and middle modules, the structure of the reconstituted Pol II-core Mediator transcription initiation complex, and reveal mechanisms of transcription regulation. We report the crystal structure of the 6-subunit Schizosaccharomyces pombe Mediator head module at 3.4 Å resolution. The structure resembles the head of a crocodile and reveals eight elements that are part of three domains named neck, fixed jaw and movable jaw. The neck contains a spine, shoulder, arm and finger. The arm and essential shoulder elements contact the remainder of Mediator and Pol II. The head module jaws and central joint, important for transcription, also interact with Mediator and Pol II. The Sp head module structure is conserved and revises a 4.3 Å model of the Sc head module, explains known mutations, and provides an atomic model for one half of core Mediator. We further propose a model of the Mediator middle module based on protein crosslinking and mass spectrometry. To determine how Mediator regulates initiation, we prepared recombinant Sc core Mediator by co-expression of its 15 subunits in bacteria. Core Mediator is active in transcription assays and bound an in vitro reconstituted core initially transcribing complex (cITC) that contains Pol II, the general factors TFIIB, TBP, TFIIF, and promoter DNA. We determined the cryo-electron microscopy structure of the initially transcribing core initiation complex at 7.8 Å resolution. The structure reveals the arrangement of DNA, TBP, TFIIB, and TFIIF on the Pol II surface, the path of the complete DNA template strand and three TFIIF elements. The ‘charged helix’ and ‘arm’ of TFIIF subunit Tfg1, reach into the Pol II cleft and may stabilize open DNA. The linker region of TFIIF subunit Tfg2 extends between Pol II protrusion and TFIIB, and may stabilize TFIIB. The structure agrees with its human counterpart, and suggests a conserved architecture of the core initiation complex. Finally, we determined the cryo-electron microscopy architecture of the cITC-core Mediator complex at 9.7 Å resolution. Core Mediator binds Pol II at the Rpb4/Rbp7 stalk close to the carboxy-terminal domain (CTD). The Mediator head module contacts the Pol II dock and TFIIB ribbon and stabilizes the initiation complex. The Mediator middle module ‘plank’ domain touches the Pol II foot and may control polymerase conformation allosterically. The Med14 subunit bridges head and middle modules with a ‘beam’, and connects to the tail module that binds transcription activators located on upstream DNA. The ‘arm’ and ‘hook’ domains of core Mediator form part of a ‘cradle’ that may position CTD and the TFIIH kinase to stimulate Pol II phosphorylation. Taken together, our results provide a structural framework to unravel the role of Mediator in transcription initiation and determine mechanisms of gene regulation.
