Scot: Many people take fish oil for a lot of different reasons. Some of the benefits, well, there's a lot of mays in front of these benefits. May support heart health, may help treat certain medical conditions, may aid in weight loss and the list goes on and on. However, we might be able to take the may off of one of those. Dr. Tom Miller is an internal medicine doctor here at University of Utah Health.

What might we possibly be able to remove the may from, as to what fish oil helps with?

Dr. Miller: Well, it's interesting. Let's start with a little bit of history. Some time ago, probably back in the '60s, maybe '50s, we understood that the native population up above the Arctic Circle, Innuits had low rates of heart disease, and it was postulated that perhaps their high diet in fish contributed to this.

Now, Arctic fish have high levels of omega-3. The idea was that if you took omega-3s, you might have less heart disease, lower incidents of stroke. This went on for a number of years, in fact a couple of decades, and it was never really very clear whether omega-3 supplements actually made a difference.

But in the last year there have been a couple of landmark studies that have employed the large number of patients required to sort this out. And it does appear for people who have high triglyceride levels and have some type of event, like heart attacks or they have coronary artery disease or they might have had a stroke, that omega-3s supplemented to their diet will prevent and lower the risk of a second event.

The exact number that they came out with in this trial is 25% reduction if you were to take four grams a day. Now that's a higher dose than most people take. Most people take one to two grams a day as a supplement. I think what needs to be determined going forward is what would be the adequate dose for those who have had an event versus those who've never had that event. Should they just take a one gram, standard daily dose, or should it be more? We don't quite know that yet.

And then, secondly, there seems to be less evidence that's it beneficial in people who have never had an event.

So it does appear for the first time that we have some pretty reliable evidence, especially in people who have had cardiovascular events and high triglycerides, that the addition of omega-3 to the diet can lower the risk of a second event.

Scot: If they take a four gram dose. Dosage is important. That was the question.

Dr. Miller: That was the study that was done on four grams. Is that the optimal dose? I don't think we know just yet, but at least we have signposts that tell us that this is going to be beneficial.

Scot: Is this something you should talk to your physician about, or if you know that you fall into this category, should you just go ahead and start taking a four gram dose?

Dr. Miller: I think it would be wise to talk to your physician, because you also want to have the rest of your metabolic profile tuned up. So you want to make sure your other cholesterol subgroups are taken care of. And that's why people are on statins for preventing secondary events of coronary disease. And then, if you high triglycerides, which statins don't treat, then it might be wise for you to start omega-3.

Interviewer: So, when it comes to opioids and being prescribed opioid painkillers, do most doctors at this point in time all operate from a similar paradigm when it comes to whether they should prescribe them, whether they should not prescribe them to a particular patient? Or do patients still need to kind of have a working knowledge of opioid pain pills? Because they scare me. I hear some of these stories and they sound a little frightening.

Dr. Miller: Well, as you know, the news is out that opioids are very addictive. The statistic is something like 80% of current heroin abusers had started out on prescription opioids. And so we have a track record in this country now over the last 30 years of overprescribing opioid narcotics for the treatment of pain, and that has led unfortunately to an increase in deaths from opioids and heroin use and other bad things.

So, in answer to your question, there is not a policy about prescribing opioids that applies to all physicians. And, more importantly, we're not yet all completely on the same page about how to use and treat people with opioid painkillers.

Interviewer: Yeah. So, to some extent, the consumer, the healthcare consumer should have a working knowledge. And as somebody that might find myself in the healthcare system, how would I know whether or not it's appropriate for me if all doctors aren't operating from the same paradigm as of yet? And why is that? Why aren't they? Is it just because the information hasn't caught up to everybody yet?

Dr. Miller: I think that's part of it. They're individual prescribing practices, and some physicians don't prescribe opioids very commonly while others do. And presumably, the ones that are now prescribing opioid for pain and do quite a bit of that are well versed in how to use that, setting up contracts with their patients on how to take opioids and when to report in and when to get their refills and so forth.

So there is a spectrum of understanding of how to prescribe opioids. It starts back with medical student training and then residency training. We have not had what I would consider to be top-of-the-mark training in opioid use throughout our medical training, and that's changing over time.

Interviewer: Gotcha. Just takes a little time for that to kind of roll out, yeah.

Dr. Miller: It takes time.

Interviewer: So, back to my original question. I asked somebody who might find themselves in the healthcare system and now I'm trying to determine, "Is this really the right course of action for me or not?" how would I make that informed decision?

Dr. Miller: That's a great question. It starts with a question. So asking your physician how your pain can be best controlled is the way to start. What is the best way that you, meaning the physician, think that your pain should be treated? How do we do that?

In general, it depends on the type of procedure you're having or the pain you're experiencing. And the plan is really to start slow and use non-opioid substances or drugs, like non-steroidal anti-inflammatories like aspirin or ibuprofen or Tylenol, or other modalities, like massage or other physical therapy efforts.

Interviewer: Which I've read, and people might find this hard to believe actually can be just as effective if not more effective than opioids for chronic pain, those types of things.

Dr. Miller: That's true. Yeah, I think we were under the misassumption that opioids treated all types of pain pretty easily as a public, and that's not true. There are many other ways to treat pain. Acupuncture is another way that works well for some patients.

But again, you have to assess the severity of the problem, the potential severity of the pain. So if you have an open abdominal procedure where the muscles of the wall of the abdomen are cut, you're very likely going to have some pretty intense pain for a while.

And then you work with the physician to decide how much pain medicine you need and for how long. So, in general, shorter courses are preferred. And you don't want to be taking large amounts of opioids for a long period of time for a problem that is healing itself.

So, again, you start with questions. You start with, "What is the best way to treat the pain you might anticipate that I will have? What is your standard of practice?" or "I have this particular pain. What do you think the best way for me to have it treated is?" And then listen carefully to what they tell you.

If it starts off with a conversation that seems unclear or moves very quickly to opioid narcotics, then you might want to ask more questions about why are we starting with that particular medication rather than something that's potentially less addictive.

Interviewer: If we were to try to draw a visual path, I have the feeling that opioids might be prescribed for chronic pain, which is long, ongoing pain, like severe back pain that you're suffering from, or it could be pain that you might experience during a surgical procedure. Those would be the two different paths possibly?

Dr. Miller: Right. So there's chronic pain, pain that you can expect to have for weeks and months and perhaps years.

Interviewer: Yeah. And those are the types of things that some of these other modalities, as you said, massage, acupuncture, physical therapy, exercise could possibly mitigate and would be a better option.

Dr. Miller: Correct. At least trying that initially or working through that without using opioids initially would be a good point.

Some of the illnesses that we've gotten away from prescribing opioids would be things like migraine headaches, fibromyalgia, types of pain that are chronic, that don't really have a well-understood initiating cause or a cause that we think is going to heal over time, or pain that is episodic. If you treat that with opioids, sometimes that leads to a higher rate of addiction.

Interviewer: Gotcha. And in a surgical procedure, say I'm going to go into a surgical procedure and my physician says, "Yeah, this is going to be pretty intense for a couple of days. I'm going to recommend opioids." They're saying it right away, but they're also saying it's only going to be for a couple of days possibly. Should I be frightened of that?

Dr. Miller: No, you should not. I think most surgeons now are very well aware of the amount of narcotics that they're going to need for the particular duration of healing that you're going to experience.

If you're getting a month's worth of narcotics for a procedure that you might expect to be out of the hospital for in several days, then that is probably too much, and you could just say, "How many days do you think I'll be needing to take these medicines?" And then you might ask to say, "Look, why don't you just give me a week or two weeks or whatever you think is best for this particular healing period?"

Interviewer: Read an interesting article. The surgical department here actually did a study that found out that, as of right now, prescribing of opioid-based painkillers after a procedure is . . . they don't take the individual into consideration. Everybody would get them whereas they felt that they should talk to each patient to try to figure out what would be appropriate for that patient.

Dr. Miller: Correct. So what that study or that . . . it's not a study, but what that approach shows is just what you and I are talking about, that every patient has an individual need for the way their pain is treated and that depends on the procedure. So it depends on the type of the procedure, the length of the incision, the area of the procedure, and then the assumed time of healing.

So laparoscopic procedures, where they make very small incisions, are likely to heal quite a bit faster and would need less pain control and possibly could be managed without narcotics. Larger procedures, possibly longer periods of time, a week to two weeks, where they might need opioids. Again, it's quite individual.

And this is another thing. The science is not well worked out in terms of why one person's pain requires more and different types of analgesics than others. It's not known yet. So everybody is a little bit different.

Interviewer: And I think that brings up an important point too, that another way that people get into trouble is they are prescribed to take a certain amount over a certain time and they're like, "Well, I know my body and I don't normally react, so I'm going to take two instead of one." And with Tylenol, it's probably not a good idea, but with opioids, it's a really bad idea to start changing that dosage.

Dr. Miller: Yes. Again, we're not entirely clear why some people start on a path and then become rapidly addicted to opioids and seek opioids for the pain relief. It's not quite clear. Some people can be on opioids for some time and stop and it's not a problem. We don't really understand that completely.

Interviewer: But maybe not a gamble worth taking if you think you could . . .

Dr. Miller: Well, yeah. What we know now, given the evidence of the '90s and the last decade, is there was too much opioid prescribing, and it did lead to higher rates of addiction. So, obviously, the more opioids that are out there that people are taking for longer periods of time or perhaps in higher doses leads to higher rates of addiction.

Interviewer: So the important takeaway from this, it sounds like, is if you're finding yourself in position where that is a recommended way to deal with your pain from a physician, to start having a conversation. Because not having that conversation and just perhaps taking those pills could lead to a place you don't want to be.

Dr. Miller: That's correct, or it could lead you to have excess opioids at home, whatever type or form you have, and somebody else could maybe use that and that would lead to some problems down the road for them.

Interviewer: What about a resource if somebody wants to read a little bit more? The CDC? Is that a good place to go to learn more? Or National Institutes of Health?

Dr. Miller: CDC has guidelines, and we've actually repurposed the guidelines in our community clinic group as a training tool and an education tool for physicians in our community clinic group to read and learn from. So the CDC would be a good place to start.

Announcer: Need reliable health and wellness information? Don't listen to the guy in the cube next to you. Get it from a trusted source, straight from the doctor's mouth. Here's this week's listener question, on The Scope.

Interviewer: Today's patient question is about sleep. This particular individual's having a hard time falling asleep at night. So they'll go to bed, they lay down, but you know, they can't get to sleep. Dr. Tom Miller, what do you recommend to your patients in that situation?

Dr. Miller: Well, first thing I ask is, what's changed? Is there more stress in their life? Is there something going on at work? Is there a family problem? Is it related to depression, perhaps? I'll look at those issues.

The next thing is, are they following a sleep schedule? Are they getting to bed at the right time, same time? And are they getting up at the same time each day? Because of our busy lifestyle we're sometimes all over the place. Monday through Friday, we may have some variable times in which we go to bed because of when we're going to work and we have morning meetings. And then on the weekends maybe we stay up late and go out and then get up late.

These kinds of disruptions in sleep patterns make it difficult, even more difficult to get a normal night sleep. The first thing I'd say is let's try to get you back into a regimented sleep pattern, so that you go to bed at the same time each night. After that try to mitigate the stress. You know, what are you doing at work or what can you do with work or family that would help you. Sometimes this may result in counseling or maybe even in the most extreme case, a change in job, you know, so that they . . . if it's bad enough, that they can get sleep.

And then ultimately if folks are still having trouble falling asleep, a short course of medication designed to help people fall asleep can be helpful. But I don't like the idea of using those long term because they have some problems associated with them. So there are number of medications on the market as prescription medications that do help people fall asleep, and they're pretty effective in small doses, for, say, up to two weeks. The other thing that I will talk to folks about is alcohol. If they're using alcohol to get to sleep, that's not a good idea.

Interviewer: All right, so you're not a big fan of the medications generally because they can actually cause more problems down the road when you stop taking them. Is that correct?

Dr. Miller: I think the problem with meditation is we jump to that as a solution before we look at sort of lifestyle issues. Whether you're, you know, increasingly stressed at work, whether you have frustrations, whether there might be depression, those are the issues that I like to tackle first before moving on to medications. You can do them simultaneously, but not assessing the lifestyle aspect of insomnia would not be the right way to approach this problem.

Interviewer: So take a look at the lifestyle, try to get that consistent sleep pattern. If you go to your physician at that point, if those other things aren't working, they might put you on a short course of some sleeping medication. If you come off . . .

Dr. Miller: As you're working on your lifestyle changes.

Interviewer: Yeah, yeah.

Dr. Miller: Getting to bed at the same time, tackling those frustrations at work, trying to regiment your lifestyle in a way that allows you to reduce the amount of stress and frustration that you might have in your life.

Interviewer: Yeah, those are underlying causes.

Dr. Miller: Underlying causes.

Interviewer: And if they get to the point where they've tried those things and they feel that they've put in a good effort towards those things, still not working, where do you go from there?

Dr. Miller: We start looking at sleep patterns and thinking about things like obstructive sleep apnea. We think about depression. Has the physician done the right evaluation to sort out whether the person has anxiety state or is depressed? There are different treatments for those problems. So, as we go down, you say an algorithm for insomnia, we will get to those sorts of things where we are digging in a little deeper to try to find a solution and treatments.

Interviewer: So it sounds like the first step for a lot of people is something they can do on their own. It's just take a look at their life and see are there causes of stress and what can I do to perhaps reduce that, maybe finding professional help.

Dr. Miller: Yeah, the majority of folks with insomnia usually have this for a short period of time. It doesn't go on for a long periods of time. So, for instance, in grief response if someone in the family has died and you're not sleeping, you know, treating that short term likely will result in a return to normal sleep patterns, as would be the case with stress at work. These things usually disappear as soon as the stress is resolved.

Announcer: Have a question? Ask it. Send your listener question to hello@thescoperadio.com.

Interviewer: You may have heard there's a new shingles vaccination, and your doctor might have recommended that you get it. Should you? Well, we'll talk about that next on The Scope.

Announcer: Access to our experts with in-depth information about the biggest health issues facing us today. The Specialists, with Dr. Tom Miller is on The Scope.

Interviewer: Let's talk about shingles. First of all, let's just set the stage. What is shingles?

Dr. Miller: Let's talk about that. So shingles is what we call recurrent chicken pox. Now, before the chickenpox vaccine was given routinely to children, most of us, probably greater than 95% of us, have had chicken pox and may not even remember it as kids. Now, once you've had it, it never goes away. The virus goes into your nerves in your spine and hides, and for reasons that are not entirely clear, probably because our immune system sort of forgets that the virus is hidden over time, chicken pox comes out again as shingles or herpes zoster. So it doesn't present as a fulminant, itchy rash like we get when we're kids, but it comes out in specific areas where the nerves innervate parts of the skin.

Interviewer: Meaning it's painful.

Dr. Miller: Well, it's painful, and what's even more concerning and more damaging, probably 10% to 20% developed what we call postherpetic neuralgia, which is a pain that continues after 90 days. And it's very severe and very hard to treat. Some people when they have postherpetic neuralgia can't even wear a shirt because it's painful.

Interviewer: Sounds miserable.

Dr. Miller: Treatments are not very good either. So the best you can do is prevent shingles.

Interviewer: And there is a shingles vaccine. And a lot of people have already gotten it, and now I'm hearing about a new shingles vaccine. So help me kind of reconcile if I should get it or not.

Dr. Miller: Well, that's right. So we say there's about a 30% lifetime chance that you'll develop shingles, and shingles rises in incidence after the age of 50, and by the time you're 80 years old, probably about 20% of people who develop shingles will have postherpetic neuralgia, which is this chronic pain that goes on and on and on.

If you vaccinate, it's basically waking up your immune system to watch out for that virus sneaking out of its hidden cave and coming back and bothering you. So the first vaccine was a live vaccine that was developed in the middle of the last decade. And it was pretty darn effective. But there's a new vaccine that is recommended even if you've had the older vaccine, that is not a live vaccine. And the advantage to that is we can now give this newer vaccine to patients who are immunocompromised. That is to say that their immune system is not quite up to par. It would have been dangerous to give them even a weakened live vaccine because they could develop full chicken pox. So we didn't we didn't give that older vaccine to folks who are immunocompromised.

Interviewer: So if you've been told you couldn't get the shingles vaccine before, now you can?

Dr. Miller: Now you can.

Interviewer: Okay.

Dr. Miller: If you have a history of being immunocompromised.

Interviewer: So that person for sure should get it. Who else should think about getting it?

Dr. Miller: Well, anyone who's over the age of 50 and certainly over the age of 60, the advantage to the newer vaccine is it is a more potent and efficacious vaccine. It works better than the older vaccine. So, in time it will become probably the sole vaccine available.

The issue with the newer vaccine is, one, it has more side effects. And two, it's costly and the older vaccine was costly, but this is a little more costly. So side effects, and what I mean by that is about 10% of the time people after getting the vaccine will develop a flu-like illness that's bad enough that they may not want to go to work.

Interviewer: So symptoms like chills, body aches . . .

Dr. Miller: Chills, aches, malaise, you just don't feel quite right. It lasts for 24 hours to 48 hours and then it's gone. This is not a reason to not get the vaccine. It's self-limited. It doesn't mean that it's going to go on. It was also a sign that this is a very immune genetic vaccine, that it is revving up the immune system and making the immune system remember that it has to go after the zoster or go after the shingles virus if it comes out of the nerves in the spine. And we know that this new vaccine is more effective in the sense that it lasts longer.

Interviewer: So if I got a shingles shot a couple years ago, and I'm 65, if I'm over 50, should I really consider turning around and getting this one?

Dr. Miller: The recommendation is to receive the new vaccination, even if you had Zostavax, the first vaccination, the live vaccination that was out.

Interviewer: At any point?

Dr. Miller: At any point.

Interviewer: Okay.

Dr. Miller: Well, I probably say, if you've had Zostavax, you would wait a year, maybe two or three years before getting the new one.

Interviewer: You can talk to your physician about that if that's the case, yeah.

Dr. Miller: You can talk to your physician. And then I think the second thing is some people assume that this particular vaccine is covered under Medicare. Certain vaccines are covered under visits during for people who have Medicare insurance, such as the flu shot and a couple of other vaccines, pneumococcal vaccine for instance. This one is not. It's covered under Part D. So you really need to find out from your insurance what the cost of this vaccine will be. The other slight disadvantage with the newer vaccine is it's a two-shot vaccine. You take the first shot and then come back in three months for the second shot.

The total course of therapy on average or treatment on average is about $340 if you were just to pay out of pocket, and for many people who don't have insurance, that's a big inhibitor. But since most of us over 65 will have Medicare and some coverage, it'll be cheaper. But again, check with your private insurance or check with Medicare to know what it's going to cost you so you don't get hit with sticker shock.

Interviewer: Yeah, and then take a look at I mean, it sounds like if it develops into the long-term chronic pain, not being able to put on a shirt, I mean, that sounds like it might be worth figuring out how you could come up with a little extra money if you're not able to.

Dr. Miller: Well, that's true. I think one of the problems that we see folks experience, they come in and they hear about it, and then they get the vaccine, but they experience the sticker shock. And either they decide not to get the vaccine or they wait.

And just as long as you know what the cost is, you can make an informed decision. And I certainly recommend it in all of my patients over the age of 50 and certainly over the age of 60.

Interviewer: It's a very common medical complaint that doctors get, dizziness. What does it mean and what can you do about it? We'll talk about that next on The Scope.

Announcer: Access to our experts with in-depth information about the biggest health issues facing you today. "The Specialists" with Dr. Tom Miller is on The Scope.

Interviewer: We're with Dr. Tom Miller, and we're going to talk about when a patient comes to him with a complaint of dizziness. What does that mean, and what can you do about it? So I come to you, I'm saying, you know, I've been feeling dizzy lately. What do you do at that point?

Dr. Miller: That's a really good question. And dizziness is one of the most common complaints that we get in primary care clinics. And basically, you have to break it down, because dizziness is just a non-specific term that means anything from fuzziness in the head to spinning to lightheadedness when you stand up.

Interviewer: All right. I'm assuming since you have to break it down, there'd be different ways that you'd handle the specific symptoms.

Dr. Miller: Right. So as soon as the patient says, "I feel dizzy," then you start to ask questions that are modifiers to how you're going to approach this problem. So, basically, one of the questions I ask, I ask them to describe dizziness. And so they'll say, "I feel lightheaded when I stand up, or I feel lightheaded when I'm getting up out of bed. I get a fuzzy feeling. I start to lose vision, or I feel like I might pass out." That's one type. The other type is, "Do you have the sensation of spinning?" which is vertigo. And that's a very specific type of dizziness, spinning. The room is spinning. You're spinning. You're moving in space. That's very different than a lightheaded feeling or sensation.

Interviewer: So if it's a lightheaded feeling and sensation, what does that mean for the patient?

Dr. Miller: Well, sometimes, it just . . . You know, this can happen in well-trained athletes. So imagine that you go out on a hot day and you run about four miles. You come back, and you're a little bit dehydrated. Your blood vessels are dilated. You sit down on the couch, you begin to watch your favorite sports show on TV, the phone rings and you jump up to get the phone, and whoa, you get wobbly. You start to lose vision. Basically, what happens there is your blood pressure dips, and you're not getting enough blood to the brain, and you start to pass out. That's a type of dizziness that causes lightheadedness.

Interviewer: Okay, that's sounds scary.

Dr. Miller: Basically, that's due to low blood pressure. It's not really scary. I mean, basically, with a couple of . . . First of all, you need to hydrate when you get home, right? Now, sometimes, it can be in people who do have problems like heart disease, or they're on antihypertensives or blood pressure medication that lower their blood pressures to a point that when they stand up and move around, they become they too light. They become to the point where they don't think they're going to stay awake. They're going to fall down. They start to lose vision. Their vision dims. Maybe they're hearing starts to disappear. And it's just this sense that they're going to go down. And so, basically, in that situation, you want to crouch down, and it pushes all that blood back up into your head. So you get down, you crouch down, and then the blood returns, and you're going to be okay.

Interviewer: Like put your head between your legs, crouch down sort of a posture?

Dr. Miller: Yeah, exactly.

Interviewer: What does that look like exactly?

Dr. Miller: Well, actually, probably the best way, if you can handle it, is to squat down. Squatting pushes blood back up into your cardiovascular system and drives blood into your brain, so that . . .

Interviewer: Staying in an upright position when you squat down? Okay.

Dr. Miller: You just squat down. Or if you really feel like you're going to pass out, you lie down.

Interviewer: Okay.

Dr. Miller: All right. And then some people get into a hot tub. They might have a half a glass of wine. They get out of the hot tub, they're relaxed. Boom, they have that sensation. That's pretty common. Basically, as soon as you sense that, and some people for reasons we don't quite understand, are just sensitive to those types of environments where, you know, they're . . . after exercise, or they're coming out of a hot tub, they might get very lightheaded when they stand up. So squatting down immediately is a way to remedy that or lying down will get the blood back to the head and resolve that problem.

Now, in the future, you have to prevent it. And to prevent it, you have to stay well hydrated. You have to be aware of the situations that create this sort of lightheadedness. So that is, again, you know, if you're exercising on a hot day and you relax, you have to realize that you need to hydrate. Also for people who are taking blood pressure medications, they need to be very aware of the situations in which they can become lightheaded, because you don't want to get to the point where you actually pass out or hurt yourself and that happens. That does happen.

Interviewer: Yeah, sure. Because that . . . It's not actually the lightheadedness that's causing the problems, it's what happens after you pass out. Right. Yeah.

Dr. Miller: Yeah, you hit your head and you really have a problem. So, you know, also think about people who are getting up in the middle of the night to go to the bathroom and they get lightheaded. It's dark. They trip, fall, and hurt themselves.

Interviewer: But otherwise, it sounds like the lightheaded type of dizziness is not, in of itself, something scary. You just need to be aware of what's causing it, try to do things to prevent it. If you feel that way, crouch down, try to get that blood back to the brain, and you're good.

Dr. Miller: In a majority of situations. Now, if you're on blood pressure medications, you may be on too high of a dose. You may need to go back to your physician and have your doses adjusted or your reason for taking those medications re-evaluated. Certainly, if you have heart failure, that is a whole 'nother issue. That's sort of beyond the scope of this discussion.

Interviewer: Gotcha. But as a general rule, that lightheaded type of dizziness, in of itself . . .

Dr. Miller: If you're aware of it and you know what you need to do immediately is get down to ground. Squat down or lie down and get your feet up.

Interviewer: Gotcha. What about the spinning kind now?

Dr. Miller: That's vertigo. Vertigo is a sensation of spinning or turning in space. It's that sensation we get when we spin around on a chair, or we turn around and around and around as little kids, you know.

Interviewer: It's been a long time since I've done that because I don't like that feeling.

Dr. Miller: Well, you could be on a fun ride at an arcade somewhere and you have that same sensation. So, basically, that is a sensation that occurs because of changes in the inner ear. So the semicircular canals, which direct sensation and position in space, have this abnormal input. And when that happens, you get the sensation of spinning. You might actually be spinning. And when you stop, you still have the sensation that you're spinning, or it may occur for other reasons.

Now, the most common reason or one of the most common reasons that people get vertigo without actually spinning around in a circle is something called benign paroxysmal positional vertigo. And this occurs as . . . in many people as, not many, in some people as we get older, where you have these little tiny particles break loose and rattle around in the semicircular canals. And what those little particles do is they bang on the hair cells that sense your position in space, and they send this very aberrant signal. And all of a sudden, you have this very strong sensation that you're spinning and turning when you're actually standing still.

Usually, this common cause of vertigo, benign positional vertigo, occurs when you roll over in bed, or you bend over to pick up a shoe, or you look up at a cabinet and try to take a cup out of the cabinet, and all of a sudden, you'll just have this incredible intense spinning sensation that lasts maybe 10 to 15 seconds. And it's reproducible usually by doing that same maneuver. Now, people when they come in and complain of this, they think they're dying, or they're having a stroke. And so it's our job to sort out whether it is temporary as it is in this benign positional vertigo. And if it is, it's likely due to this little particle that's banging around in the inner ear. And there's treatment for that. It's actually physical therapy.

Interviewer: Okay.

Dr. Miller: You could do a maneuver, and usually the maneuver will help put those little particles back where they belong . . .

Interviewer: Really?

Dr. Miller: . . . and then, you're okay. You're on your way. In some cases, if it's worse, we send them to an ear, nose, and throat specialist, and they do their special work, and that takes care of it.

Interviewer: Just want to make sure that I understand. So the lightheaded type of dizziness, unless you're on some sort of medications, sounds like it's not necessarily something you need to mention to your doctor?

Dr. Miller: You can if it's recurrent. I mean, obviously, if you're having situations where it's occurring more frequently and it didn't occur before, that's something you probably should see the physician about.

Interviewer: And the spinning type?

Dr. Miller: The spinning type is something that most people will seek attention for because it's so intense. And you know, if it's bad enough, it'll cause you to throw up. And it's so abnormal and unusual that people seek care for that.

Interviewer: Gotcha.

Dr. Miller: And there is treatment. There's treatment. There are less common causes of vertigo, viral causes where you just all of a sudden have intense spinning sensation and you're sick for three or four days and you're bedridden and sometimes hospitalized because you can't keep any food or fluids down. And that eventually resolves.

Interviewer: Gotcha. So in both of these . . .

Dr. Miller: Sometimes, even more rarely, it would be a stroke.

Interviewer: In both of these instances, perhaps talk to your primary care physician if it's becoming something that happens a lot?

Dr. Miller: Right.

Interviewer: And you know, not only for your quality of life but your peace of mind. But as a general rule, neither one of these two things sounds too threatening?

Dr. Miller: Not too threatening, but can be pretty scary if you haven't had them occur before. And I would think that most people from time to time have experienced the lightheaded kind of dizziness, and they usually will figure out what causes that. It's usually getting up too quickly.

Announcer: Access to our experts with in-depth information about the biggest health issues facing you today, "The Specialists" with Dr. Tom Miller is on The Scope.

Interviewer: Fatty liver disease affects more than 80 million Americans, and many of them don't even know they have it. Dr. Tom Miller, why does fatty liver disease concern you as a doctor?

Dr. Miller: Well, fatty liver disease is becoming the most common chronic liver disease in the industrialized Western world, and especially in the United States. And it used to be, we had viral hepatitis as a cause of liver disease and a major cause of transplantation, which it still is, but very shortly the major reason for liver transplantation due to liver failure is going to be fatty liver.

Interviewer: And not necessarily caused by alcohol. I always thought it was, you know, people that drank a lot tend to get fatty liver disease.

Dr. Miller: Well, they get liver disease. It's not necessarily fatty liver disease as you would think about it, and it was and still continues to be a cause of liver disease, but because of our lifestyle and the fact that 30% of the people living in the United States have obesity, fatty liver disease is now the most common cause of chronic liver disease.

Interviewer: Yeah, 80 million Americans, that's quite a . . . that's almost an epidemic, isn't it? Like, if 80 million Americans had any other sort of disease, we would be freaking out.

Dr. Miller: Right. I think the term might be just a little bit . . . The categorization of it is a little bit misleading because not everyone with fatty liver disease goes on to develop liver failure. In fact, a small percentage of those people end up with liver failure, but given the large number of people with fatty liver disease, a significant number of Americans will end up with end-stage liver disease.

Interviewer: And what exactly is going on? So I think the name implies that there's some fat, maybe excess fat deposits in the liver, but why is that bad?

Dr. Miller: Fat is a cause, a driver of inflammation, and we don't exactly know why, but when people gain weight, some of that weight is stored centrally and also stored between the cells in the liver. So if you look at a person's tissue from the liver, you will see if they have fatty liver, which is called non-alcoholic fatty liver. You'll see fat stores or globules in between the cells. For whatever reason, this causes inflammation, and inflammation predisposes to damage, fibrosis, and destruction of the active cells in the liver which help us cleanse our body of toxins.

Interviewer: And you're talking about scarring.

Dr. Miller: I'm talking about scarring.

Interviewer: That's why I used those words, yeah.

Dr. Miller: Fibrosis leads to scarring.

Interviewer: Yeah.

Dr. Miller: Now, again, most people with fatty liver don't end up with inflammation, and we don't exactly understand why some people have problems with inflammation related to their fatty liver versus those who don't. And not everyone who has inflammation in the liver goes on to develop cirrhosis.

Interviewer: But it's certainly a path you don't want to go down and find those things out.

Dr. Miller: No, definitely not, and it can be treated.

Interviewer: All right. So, when a patient comes into your office, can you look at them and tell if they have the bad kind of fatty liver disease that could lead to transplant or death?

Dr. Miller: I think the way that we think about it now, I believe the way we think about it now is if you're obese, that is you have a body mass index greater than 30, your chances are pretty high of having non-alcoholic fatty liver disease. So, basically, the same thing that we've talked about on these shows in the past, right diet, right weight, right exercise is your best treatment to prevent it. This is a problem with industrialized countries having too much food and the wrong kinds of food available.

Interviewer: Yeah. And once that scarring happens, there's no cure for it. It eventually will lead to liver failure.

Dr. Miller: Once you start down a path of scarring, your chances of ending up with end-stage liver disease and needing a transplant are pretty high. Not only that, you are predisposed, with that scarring, to liver cancer.

Interviewer: And if you start to lose some weight, I understand it doesn't take, necessarily, a lot of weight reduction to reduce the number of fat cells in the liver and kind of start backing that thing up if scarring hasn't occurred.

Dr. Miller: Right. I think one, again, wants to head for a normal BMI, which is between 18.5 and 25.

Interviewer: Okay.

Dr. Miller: And that's not easy. I mean, I tell you that that's the treatment, but attaining that treatment for everybody is difficult because we don't have a medication for weight loss that works, and basically it's a lifestyle adjustment, which is hard for people given the abundance of food.

Interviewer: And there are tests that you can do to determine, for sure, if there are.

Dr. Miller: There are. So we basically start looking at the issue of inflammation in people who we think might have fatty liver disease by looking at the enzymes that the liver produces on a blood test. If these are elevated, there are a number of causes, but eventually, if you can rule out sort of the medical, the drug-associated causes and other causes, that is if they're not drinking, you can think that this is probably related to a non-alcoholic fatty liver disease. And if you really want to know damage to the liver, you're going to have to do a liver biopsy. There's another test now that's non-invasive, but liver biopsy is still the gold standard.

Interviewer: And we haven't really hit on this, but it often doesn't have symptoms.

Dr. Miller: The vast majority of people with non-alcoholic fatty liver disease are not symptomatic.

Interviewer: Yeah.

Dr. Miller: And, in fact, you're only symptomatic towards the end . . .

Interviewer: When it's kind of too late.

Dr. Miller: . . . with this disease when you have fibrosis and scarring or liver cancer. So, again, we want to look at obesity and lifestyle as a response to prevent this.

Interviewer: So get that body mass index back into a reasonable area?

Dr. Miller: Well, it's the same thing we talk about for all of the things that we now kind of associate with the Western world diet, which is high blood pressure, heart disease, metabolic syndrome, type 2 diabetes. They're all in a basket, including this non-alcoholic fatty liver disease. And, again, the treatment is at our hand, but it's not easy to achieve.

Interviewer: Rosacea is a chronic and potentially disruptive disorder that causes itching, redness, and unsightly bumps on the face. It can continue to get worse without treatment, so early detection is important. Dr. Miller, what patients are at risk, and what should they be looking for?

Dr. Miller: Most cases appear between the ages of 30 and 50 years old and may afflict people with fair skin, basically those of northern European ancestry. Women are more likely than men to develop it, and there is usually a family history. So, if a patient is at risk for rosacea, the key is to seek treatment early.

Interviewer: And what are the signs to look out for?

Dr. Miller: Flushing and redness on the cheeks and nose that last unusually long, and one can also have tiny visible blood vessels on the face, and these signs are commonly accompanied by stinging, burning, and itching. If you see any of these signs, you should see your doctor or dermatologist for diagnosis as there is excellent treatment.

Announcer: The Health Minute, produced by University of Utah Health.

Interviewer: All right, here's the scenario. My wife is blaming me for giving her a cold that I had, but her symptoms are completely different. So, Dr. Tom Miller, is it possible for different people to come down with different symptoms from the same bug? Am I really responsible here?

Dr. Miller: People can come up with variations on the theme but caused by the same virus or same bug. Could she have gotten it from you? I would say that if you actually picked it up two weeks ago and you were better in about four or five days, or starting to get better, that she would pick it up a week later, it's possible but probably less likely. And I think the bigger thing is that these viruses tend to circulate in the community. So you could pick it up from somebody at work, you could pick it up in the grocery store. And so what's your best defense? Wash your hands. Wash your hands during the cold and flu season, especially if you're around someone who has a cold. Just make sure you wash your hands frequently.

Announcer: To find out more about this and other health and wellness topics, visit thescoperadio.com.

Interviewer: You have a pretty bad sore throat. Dr. Tom Miller, is that worth a trip to the doctor?

Dr. Miller: It might be. Most sore throats are caused by viruses. But if you have tender, swollen lymph nodes in your neck, if you have a fever of greater than 100 or 100.5, and if you look in the back of your throat with a penlight and you see sort of plaques on your tonsils, there's a good chance that you have strep throat, especially if you live with young kids who also get strep throat more commonly than adults. It might be worth a trip to the doctor.

He'll evaluate those same things. If you have all three of them, he's likely to give you an antibiotic. If you have one or two of them, he'll do what's called a rapid strep test. That will tell him if you have strep throat, and if you do, you'll have an antibiotic. That will reduce the symptom duration by one or two days and you'll feel better and get back to work.

Interviewer: So strep throat pretty much the only sore throat that you're going to get an antibiotic for.

Dr. Miller: There are others but more rarely.

Interviewer: You go to your doctor, they say your cholesterol is too high. Why should you care and what does that mean for your health? And what can you do about it? That's next on The Scope.

Interviewer: All right, Dr. Tom Miller, you know every year you go get you physical. One of the numbers you're going to get back is your cholesterol numbers. There are two or three of those numbers, and my doctor my tells me, "Oh, your cholesterol doesn't look good." What's going on?

Dr. Miller: Well, we've known for many years that high cholesterol can generally imply poor outcomes in the long term. It's related to vascular disease over many, many years, and it's associated with other risk factors for vascular disease, such as high blood pressure.

Interviewer: And which all can lead to heart attack or stroke?

Dr. Miller: Exactly.

Interviewer: Yes. So that's why if you see those high numbers they're predictor score, that this person is more likely to have those outcomes.

Dr. Miller: That's exactly right. So there's several things when people talk about cholesterol. Let me break those down real quick for you. First, is total cholesterol. And generally, if your cholesterol is over 200, that's too high, but you can break it down further from there. You break it down into triglycerides, you break it down into HDL, that's the good cholesterol, and then you break it down into LDL, the bad cholesterol. The way I kind of think about, Scott, is when you have a high HDL, that's the good stuff, it reminds me of a taxi that's ferrying sort of cholesterol and bad stuff away from the arteries and takes that back to the liver where it's chewed up and metabolized, and you don't have to worry about it anymore.

Interviewer: So you want lots of that HDL to help your body dispose off that stuff.

Dr. Miller: Yes, high HDL is better. High HDL is better.

Interviewer: Okay.

Dr. Miller: And you know how you get high HDL? Exercise.

Interviewer: Oatmeal. No, exercise.

Dr. Miller: Well, not so much oatmeal but exercise and weight loss and stopping smoking actually raises HDL as well. So really, what you do when you do those three things is you increase the number of taxis that are delivering bad cholesterol away from the arteries into the liver where it's chewed up. LDL, you think about that as a taxi taking cholesterol down to the arteries and depositing it into the sides of the arteries into the lumen or the walls of the arteries. And so that's where it sits, and over long periods of time, you get these plaque build-ups, and if those plaques rupture, then you can have bad things like a heart attack or a stroke.

Interviewer: So is the total cholesterol a sum of your HDL/LDL in the triglycerides? Is that where that number comes from?

Dr. Miller: Yes, basically, there's a little equation of that, but not to trouble ourselves too much about it. But the higher the HDL, the higher the total cholesterol. The higher LDL, the higher the total cholesterol. So if you actually have a nice high HDL and a low LDL, that's okay if your total cholesterol is just a little elevated.

Interviewer: Okay.

Dr. Miller: So total tells you kind of, is a sign post about you need to look at this more closely.

Interviewer: Okay. So you get that big number. Well, if the number is not big then you're probably fine. But if it's a big number then you need to look at how does that break down; the good versus the bad. If you got more good, fine.

Dr. Miller: Well, sometimes you can look at that ratio too. So you can look at that ratio total cholesterol and HDL. And there are calculators now that are put out by the American Heart Association in conjunction with the American College Cardiology that look at not only the total cholesterol and HDL, but they mix in your blood pressure and your other risk factors, whether you smoke, whether you have diabetes, and if you're on blood pressure medication. And it gives you score, and that score kind of tells you what your 10-year risk is.

Now, no calculator is perfect, Scott, but it's a pretty good indication of, "Wow, I'm doing really well. I'm eating right. I have low blood pressure and I don't have other risk factors," or, "Warning, I've got to do some other things to improve my health." Now, one of these things might be that you need to take a medication to lower your cholesterol while you're waiting for the lifestyle things to catch up.

Interviewer: Let's go back to the original question. Your doctor is concerned about your cholesterol numbers, so odds are at the point what he's going to say is you have high LDL, which is bad.

Dr. Miller: That could be one thing he says . . .

Interviewer: Exercise. I need you to exercise more. I need you to quit smoking.

Dr. Miller: Right, and you would say those things anyway, right?

Interviewer: Okay.

Dr. Miller: I mean, generally, those are great ideas, but we stress them more if your cholesterol and blood pressure are elevated.

Interviewer: What else would you doctor tell you to do to try to get that under control then?

Dr. Miller: So you want to follow a low cholesterol based diet, and there are ways to do that. You can Google a step one cholesterol diet and it will tell you. And basically, it's common sense. Don't eat a lot of animal products because animal foods have cholesterol, plants don't, they don't have cholesterol. So you're not going to get cholesterol from plants, so the more vegetarian based your diet is, the more leafy green vegetables you eat, the chances are you will help lower your LDL cholesterol.

And so you want to stay away from high cholesterol meats, fatty meats. You want to trim fat off of any kind of meat that you are eating chicken or steak, and some common sense things. And most of us have heard these over and over on the news and on the media but we have to pay attention to it on the cholesterol side. But at some point it might be high enough, you actually need to be treated for it.

Interviewer: You could do all the right things and still . . .

Dr. Miller: Yes, there are some folks that have a genetic predisposition to have high LDL cholesterol and they are predisposed to really heart disease. And so we do get after them with drugs and we have good drugs now to treat high cholesterol.

Interviewer: And nothing you can do if you're genetically disposition, if you do all the other stuff right.

Dr. Miller: Yes. First step in this treatment basically, and this is true for high blood pressure as well, is to get after your lifestyle improvements. So getting your body mass index down between 18.5 and 25 and exercising on a daily basis. And I'm not talking about on Schwarzenegger type weight room stuff, I'm just talking about going out and getting to walk for 30 to 60 minutes a day.

Interviewer: Elevating that heart rate.

Dr. Miller: Yes, getting your heart rate up to a moderately elevated level. We're not talking about Olympian athlete type redlining heart rates, we're just talking about getting out and doing a brisk walk or a swim or cycling.

Interviewer: Do you find that patients when you give them this information that they tend to think, "Well, really how much is that going to make a difference?" Are they skeptical?

Dr. Miller: I don't think patients are skeptical. I think we all want to do the right thing. And I think the vast majority of us believe that exercise is healthy. It makes us feel better and losing weight makes us feel better. There's a body image piece there. It's just hard to do. We don't have a pill to help you lose weight effectively.

Interviewer: And for cholesterol. . .

Dr. Miller: And we don't have a pill to make you exercise. So it's a lot of coaching. It's like you can do this, go out and do it. So you build your patient's will power up by suggestion.

Interviewer: And doing that will noticeably decrease cholesterol numbers?

Dr. Miller: Yes, it will definitely help reduce cholesterol in the vast majority of people, but not always to a level that would be necessary.

Interviewer: Got you. But it does make a difference?

Dr. Miller: It does make a difference, and it a makes difference for reasons other than just lowering cholesterol and lowering blood pressure. So there's many different reasons to stay healthy with lifestyle interventions.

Dr. Miller: Thin bones and the risk of fracture and what to do about that. We're going to talk about that next on Scope Radio.

Announcer: Health tips, medical news, research, and more for a happier, healthier life. From University of Utah Health Sciences, this is The Scope.

Dr. Miller: I'm Dr. Tom Miller and I'm here with Dr. Nick Spina, and he's an orthopedic surgeon here at the University of Utah, in the Department of Orthopedics. He's an expert in spine care. Nick, how do you get a fracture when you have thin bones or osteoporosis? What happens? Where do they occur typically in the back? Tell me about that. It's a lot at risk.

Dr. Spina: Yeah. Osteoporotic compression fractures or what we call fragility fractures are probably the most common fracture we see in spine surgery. It tends to be on the more elderly side of the population.

Dr. Miller: At the time when we lose our bone mass.

Dr. Spina: Exactly, at the time when we lose our bone mass. So I'd like to describe them to people to imagine a soda can or a pop can. And each patient's vertebral body is like a pop can. So it has a hard rim on the top and a hard rim on the bottom, and the center part of the can is relatively empty. As we age and we get osteoporosis, the center of the can becomes even more empty. And so, as we stress the top, the can eventually cracks and crushes where our end plates become closer together or the ends of the can become closer together.

Dr. Miller: And so, what happens to precipitate that fracture? My understanding is they could just happen spontaneously if your bone density is so low.

Dr. Spina: Right. Depending on the degree of your osteoporosis or the degree of the strength of your bone, it can happen with just minimal activities such as waking up from sleep, standing, walking. They are commonly precipitated from falls, so patients often come in after a fall from standing or a fall during gardening, or routine activity around the house where they develop an acute onset of back pain.

Dr. Miller: Or one of the favorites from my patients would be shoveling snow.

Dr. Spina: Exactly. It seems no one should shovel snow anymore. That's pretty much a general rule.

Dr. Miller: So what happens? Do they have pain typically after that?

Dr. Spina: So the most common presenting symptom is acute back pain. Some of the worst pain you've had in the center of your back. It tends to be localized to the midline or right in the middle. Our muscles also become very inflamed, so it can radiate out towards our rib cage. It tends to be in the mid portion of the back. For women, right around their bra strap, and for men, kind of in-between the shoulder blades.

Dr. Miller: Now, you would find more osteoporotic fractures in women, I would think, right?

Dr. Spina: It does.

Dr. Miller: Osteoporosis is more common in women.

Dr. Spina: It's more common in women. So we do tend to see more osteoporotic fractures in elderly women versus men.

Dr. Miller: So, aside from analgesics, pain killers, that type of thing, what can you do to alleviate the pain or help with the pain?

Dr. Spina: So we sort of take a two-tier approach. One is a reduction in activities and modification of daily living, to avoid those activities such as heavy lifting, bending over at the waist, stressing the spine by bending forward or twisting. And the second would be we occasionally use a brace to provide an external support, kind of external crutch you can think of to keep the spine upright or support it while a bone tends to heal in that compressed manner.

Dr. Miller: What's this brace look like? Is it corset?

Dr. Spina: Yes. It tends to be a corset. It kind of looks like a turtle shell, hard in the front and hard in the back, and it wraps around your torso.

Dr. Miller: And usually, how long would a person have to wear that for that to work?

Dr. Spina: We tend to use them for about two months. And then, we tend to wean out of it because as we put people in braces, their muscles, obviously, become weaker. And having good muscular strength is one of the ways we compensate for having fractures. And so we don't cut them cold turkey. We often ask people to slowly come out of them and wear them when they're upright or up for long periods of time, and then remove them when they're sleeping or sitting.

Dr. Miller: Now, tell me a little bit about what's call kyphoplasty. I understand there's a little bit of controversy about the use of this technique and has been for a number of years.

Dr. Spina: So kyphoplasty and vertebroplasty were very common about 10 to 15 years ago. They sort of exploded in the world of spine surgery. And the procedure itself is directed at restoring the height of that pop can. So what we do is . . .

Dr. Miller: So this maintains height in the patient. So the concept, I guess, was if you increase the height of the crushed pop can, then the person wouldn't lose height.

Dr. Spina: Exactly. And so we insert a probe from the back of the spine into the front, the vertebral body. And there are two different means. One, we use a balloon to try to restore the height of the body. And the second is we just inject a material to try to restore the height. And the bottom line is that we take the empty space in the vertebral body, that space that's crushed down, and we try to stabilize it and if not, restore it by putting cement in the front of the vertebral body.

Dr. Miller: So what is the controversy surrounding this technique?

Dr. Spina: So there have been a couple large studies that have been done, that have looked at patients who have not had vertebroplasty or kyphoplasty and who have, and they haven't shown much of a difference as far as long term outcomes. So, in my practice, we tend to reserve them for those patients with intractable pain after about six weeks of non-operative care.

Dr. Miller: So they have some role in alleviating pain if it's not treated with the standard sort of non-interventional means that you just spoke about a few minutes ago?

Dr. Spina: Exactly. In those patients out of refractory which are very, very few in my practice, tend to see a little bit of benefit from doing a kyphoplasty. But again, we tend to reserve that to those people that fail all the non-operative means which we start with in the beginning.

Dr. Miller: The other point would be that if a patient has osteoporosis, they should also be treated for that with one of the newer medications. I should say newer. The medications have been around now for 10 years, and there's new medicines coming out all the time.

Dr. Spina: Exactly. One of the biggest risk factors for vertebral body compression fracture or fragility fracture is having a previous fracture. So it's our routine practice when we identify these patients to make sure that they have a pipeline of care through either us as treating providers or their primary care physicians to check their bone quality through a DEXA scan and address the degree of osteoporosis that they have.

Dr. Miller: Screening becomes very important in this age group, especially women over 65 years of age.

Dr. Spina: Exactly. Screening is probably the best form of prevention for these fractures that we have.

Interviewer: If you break bone, do you still get a plaster of Paris cast that your friends can sign? We're going to talk about that next on Scope Radio.

Announcer: Access to our experts with in-depth information about the biggest health issues facing you today. "The Specialists" with Dr. Tom Miller is on The Scope.

Dr. Miller: Hi. I'm Dr. Tom Miller and I'm here with Dr. Bruce Thomas. He's an orthopedic surgeon here at the Department of Orthopedics at the University of Utah and also practices at our Farmington facility in Farmington, Utah.

Bruce, do we still use plaster of Paris? I mean, when I was training, we'd go into the cast room and they had this big, goopy bin full of plaster of Paris. And they wrapped you up and put all the plaster of Paris on there. It dried and then your friends wrote all over the cast. Times change a little bit or not?

Dr. Thomas: For most things, times have changed.

Dr. Miller: I would suspect.

Dr. Thomas: Plaster is . . . It's been good. It's traditional. It's heavy. It's dirty. And for a long time, orthopedic surgeons felt like it held the molds better. There are studies that show that fiberglass will hold the mold that we put on the cast as well as fiberglass. And when we mold the cast, we put pressure on the bones in the right place to hold the fracture in place. The orthopedic axiom is crooked cast, straight bone.

Dr. Miller: So you can mold the fiberglass right around the arm or leg in the same way that you did with the plaster of Paris?

Dr. Thomas: You can. And when they've looked at it scientifically, the results were very similar.

Dr. Miller: So I suspect it's a lot lighter than that big, clubby plaster of Paris cast that people wore around for eight weeks.

Dr. Thomas: Significantly lighter, much cleaner, and your friends can still write on it.

Dr. Miller: That's great. How about the cast itself? These fiberglass casts, can it be removed so that you can shower or put back on? Does that just depend on the type of fracture?

Dr. Thomas: It does. It depends on the fracture and how stable it is. Once the fiberglass is on, it's not easy for the patient to take it off, but we can cut the cast and make it removable, if there is a fracture that is stable and we're not worried about a lot of displacement.

Dr. Miller: So casts are lighter. You can still write on them. And sometimes you can even take them off to take a shower.

Dr. Thomas: True.

Announcer: Need reliable health and wellness information? Don't listen to the guy in the cube next to you. Get it from a trusted source straight from the doctor's mouth. Here's this week's Listener Question on The Scope.

Interviewer: Dr. Tom Miller, we have a question here from Lisa in Sandy, Utah. She apparently had a cold and feels like she's over her cold, but yet this cough kind of is persisting. Is that something to be worried about? What is that? What's going on?

Dr. Miller: Usually, not. There's two points. One, could it be serious? Is this something that you need to worry about? And again, you go back to worrisome signs and symptoms. So if you have fever, if you either have a measurable fever and you're continuing to cough or you feel like you have a fever or you have night sweats, then that's something you need to get checked out. If you're coughing up a lot of sputum, you know, thick, gunky, smelly sputum, that's something you need to get checked out. If you have rib pain, if you're short of breath, that's something you need to get checked out.

Most of the time with a viral infection, an upper respiratory tract infection, you're sick for anywhere from three to seven days, and you get over it. I mean, you cough a little bit and you're hoarse, and then it goes away.

Interviewer: Are we talking about a cold when you say . . .

Dr. Miller: We're talking about a cold, an upper respiratory viral infection. I mean, everybody gets those in the winter and sometimes in the summer and spring, but mostly in the winter.

So what do you do? You have this cough. It's called a post-viral cough. It's not productive. It's annoying. It's probably due to the fact that the virus, which is gone after seven days, has irritated the bronchial lining and the cough receptors in your airways, and they continue to produce this cough reflex and you continue to cough. And it can go on for eight weeks, sometimes ten weeks.

Interviewer: What?

Dr. Miller: A long time. I know patients who have had chronic cough that's not productive after a viral illness, after a cold that goes on a couple of three months, and there really is no good treatment for it. A lot of those antitussives, those cough medicines you can buy at the store, they really don't work. And so it's nagging.

And sometimes though, patients who do have chronic cough might have asthma or might have asthma triggered by the cough, and so it doesn't hurt if you're really struggling with that cough to go see a physician to see if there could be something else causing it. You know that you haven't had any worrisome signs, you're not worried that you've got pneumonia or some other bad thing going on, but the cough is just driving you nuts, go see a physician about it. You might have an asthma variant of the cough, which could respond to treatment, inhaler or something like that. But a lot of times, you're just kind of stuck with it until it goes away, which is really bothersome, but we don't have great treatment for that.

Interviewer: And most of the time, that's what the case is after a cold and I continue to have a cough for two or three weeks afterwards.

Dr. Miller: Correct. Now again, the vast majority of patients that get colds, they get better, and only it's a small percentage with this chronic cough.
