facebook or twitter. that's all for now. i hope you've enjoyed the show and are learning to be more of a healthy you. althier you. i'm eric shawn. time now for "sunday housecall." >> i'm arthel neville. welcome, everyone. joining us is dr. david samadi, chairman and professor of urology at lenox hill hospital and chief of robotic surgery. >> and dr. mark siegel, professor of medicine. he's the author of "the inner pulse, unlocking the secret code of sickness and health." >> we're going to start here, it's already available for use in the european union, canada and australia. so now a drug meant to help patients dealing with the

effects of multiple sclerosis has been approved for use right here at home. dr. samadi, you know we may even know someone who is dealing with m.s. we don't really know what it is. can you explain to us what m.s. is? >> it's the most common autoimmune disease of central nervous system. brain, spinal cord, and optic nerve. what we really mean is that, you know, in the brain and spinal cord, we have a lot of nerves that connect with each other. neurons that send signal from one cell to another cell. if you decide to walk, if you decide to lift up a pen, a lot of mechanism that goes behind this to pass the signal. just like electrical cord, they have a sheathe around them. a plastic sheathe which we call myelin. in ms, what happens is, our own body, autoimmune disease, the soldiers that are supposed to defend us, they go against us and attack these sheathes. the plastic cover of the electricity wears off.

so what happens? all the message leaks out of our system so movements are not in sync. you have bladder spasm, bladder incontinence. you would have walking problems, visual issues. that's really what m.s. is. this was discovered and described in 1868. i was 2 years old at that time. it was described by someone, a french guy, who was brilliant. he described it as multiple scars. then eventually became multiple sclerosis. so there's a deficiency in the passage of the inflammation from one cell to another one. we have treated this. there's no cure for this. we have treated with a lot of chemotherapeutic medications. something called lemtrada. it is used for treatment of leukemia, but now it's approved for this disease. it's antibodies that slows down the immune system so it doesn't eat up those cells.

a better treatment would be to use stem cells and prevent this from happening. if there are any companies that are working on this, i would love to hear from you. it's mostly used for relapse. unfortunately, it's not the biggest news we can bring to you. >> how do you know if you have it? >> because it's called the great imitator, it's another great imitator like sif lus. it's hard to know if you have it. it can present with a lot of different things. usually the first stomach is a vision change. that's something that could really be multiple sclerosis. fatigue, spasm, tingling in fingertips and loss of sensation, very, very common with ms. it's an autoimmune disease. our own immune system is attacking our nerves. prior to this, we used autoimmune treatments that stopped the immune system from targeting the nerve cells.

what's interesting about lemtrada, it's a very targeted treatment that stops these immune cells from bearing right in on the nerves. it's extremely promising. 70% of the people tested went into full remission after a full year of treatment. very expensive, though. $150,000 for two treatments. >> and side effect. >> headache, nausea, vomiting and rash. >> i think a lot of patient with ms go on for a long time without correct diagnosis, how distinguish between that lupus and something like ms. i think that's always a big problem for doctors. >> and, you know, fibromyalgia is actually hard to diagnose. lupus, you can check a blood

test. with ms, you check an mri of the brain. you look for damage to that sheathe. if they're damaged, you're going to see scars. if you see enough of them, a good neurologist will say this is ms. >> we're talking about this drug already in use, now it's coming here to the u.s. when will it be here and exactly what does it do for the patients? is it the same drug you just referenced that's so expensive? so if it is, will insurance cover it? >> most insurances are going to cover it, i believe. the side effects or the issues why it wasn't approved about a year ago, this drug has come multiple times for approval in this country, but it was rejected because of the side effects. what the company wants you to know is, it's not the first line of treatment. it's really for the people that relapse.

we're using some things, a lot of other medications for ms. if it doesn't work well, this would be a second backup and i think it's going to be available very soon. most of these autoimmune diseases are very hard. when you look at the mri, you e white matter. it's the white matter that has a problem in this case because our system attacks it. it's a long process. usually this is between 15 and 45-year-old. the average is about 30. unless there's early treatment, the outcome is not so good. >> this may be controversial, what do you think about the whole medicinal marijuana treatment? >> it's a good question. very good question. of course i feel that can be overused. for ms and people having a lot of pain in later stages, it can be quite effective. i do want to explain, by the way, what relapsing and remitting is. that's the most common kind of multiple sclerosis, and that's

what we're talking about today. you get an exacerbation. you get something like loss of vision, you get spasm, you get some weakness and then it comes back. so it's episodic. it progresses but then it comes back. you go into remission, but then it starts all over again. >> let me just say one quick thing about medical marijuana. i've always been against it. i think for very specific type of patients, under supervision of doctors, it may have some effect and it would work. the way medical marijuana is being done right now, everybody is basically sharing it with other friends, i think that really needs to be controlled. >> i agree. >> okay. >> all right. very good news today. well, there's eye-opening news about contact lens. do you wear them? you ever sleep with them accidentally in? do you neglect to always clean the solution? if so, you may be harming your health. the biggest dos and don'ts for contact lens wearers up next on

"sunday housecall." for

test. which

and back now with "sunday housecall." do you wear contact lenses? an estimated 38 million americans do. but the centers for disease control says not everybody takes cake of their contact lens the way we all should. that's causing a number in the spike of visits to the emergency room. i tried them once. i don't know -- you have to put them in, take them out, clean them, it goes on and on and on. >> i can't see you with contact lenses. >> you're sticking your finger and and you got the germs. that's one of the problems. >> you need to wash your hands. >> i can't see eric doing that.

>> david samadi is a surgeon. i trust him with them. i was the worst. preparing for this segment, i'm saying thank god i don't wear these things anymore. 38 million contact lens users in the united states, 1 million infections. now, the conjunctiva is the colored part of the eye -- the covering the colored part. that's where the lens goes. it's also probably the most important part to preserving your vision. if you get an infection there, you can get a scar in the cornea. you can even go blind from this. rare, but this is a serious matter. what do you do? you got to wash your hands with soap and water before you put your contact lens in and you got to dry them. if you introduce wetness into your eye, that increases the risk of infection. we have a chart on this. you have to dry your hands well. you have to take them out before bed, before showering, before swimming. i was worried about losing them in the pool.

what actually happens is that you can get an infection in your eye. rub and rinse each time you remove them. i didn't do that either. you got to disinfect them each time. you have to store the lenses upside down with the caps open. you have to replace contact lens case at least once ever three months. i used the same old thing for years. >> people don't think of that. >> carry a spare pair of glasses. if you can't clean it properly, if you're in some toilet at a gas station, you want to put your glasses on and replace your contact lenses too. >> sometimes forgetting to take them out when you go to sleep. what happens when you wake up in the morning and your eyes are scratchy. >> that's actually one of the biggest problem is that people want something easy. they don't want to put them in and take them out. that's when you end up having this kind of inflammation. it's a serious problem. it's inflammation of the cornea. the white area on the outside.

>> is that like conjunctivitis? >> similar to that. it's very painful. if it's not taken care of, sometimes you can get even herpes simplex or fungal. there are many different types, different treatments for them. in this particular case, 1 million visits to the emergency room, $175 million. it's unbelievable. $175 million the cost of this. but if you follow the property comes we just put up, this is a common sense segment. you don't even need doctors to tell you. >> we do need doctors. >> wash your hands and make sure -- >> we're giving you a reminder. >> what about the extended wear contact lenses? >> that's a good one. i think the way to take care of this is every three to six months, you should try to change them. you change your toothbrush every three months. you change the contact lens every six months.

extended every three to six months. >> what about if you get a cold? i change is my -- i change my toothbrush if i get a cold. what about that? >> that's a great point. there again you're introducing some virus into your eye. every time you touch that contact lens. again, it's the area of the eye just over the colored part. it gets infected. it's a very thin area actually. if it gets infected, it can get scarred. then you have to use antibiotic drops. we can get rid of it in most cases. >> i think if you rinse it in a multipurpose solution. this is also not to scare a lot of people. you just have to be careful. if you use a multipurpose solution, your hands are clean -- >> do it every day. >> i think it's good to change this disposable ones every once in a while so you don't carry the germs. >> now i got to change my

toothbrush. >> about time. >> hey, got milk? well, it's supposed to be a healthier alternative to regular milk, but is soy milk really all it's made out to be? we're going to separate medical fact from fiction on that one. stick around. we're going to separate medical fact from fiction on that one. fact from fiction on that one. stick around. i take prilosec otc each morning for my frequent heartburn. because it gives me... zero heartburn! prilosec otc. the number 1 doctor-recommended frequent heartburn medicine for 9 straight years. one pill each morning. 24 hours. zero heartburn.

>> back to sunday house call in the weekly segment county should i worry, we talk about everything that worries us, and you tell me the youth about soy products. soy milk helps with the hot flashes but does it increase the

chance of breast cancer? >> it is a very good question. we are surrounding by a lot of soy products. whether it is tofu, et cetera, soy milk, in 90 percent of the soy in this country is engineered, not the kind of soy products in asia where it is fermented and they have reduced the amount of estrogen and they take a small amount not the amount we take. a lot of the soybean proteins are in processed food which is not so good because it has omeg omega6 saturated fat. in general, i am not a big fan of soy and soy products. in has been a lot of studies that are controversial, reducing prostate cancer. we are not sure. reduced heart disease. we are not sure with confidence. in the past, there have been issues on soy and fertility in men and many other things we

have seen including increasing breast cancer which has to do with estrogen which takes care of hot flashes but it could cause breast cancer. >> are there studies? have they proven there is any link? >> in human clinical trials, the group that took soy had increasing number of cells in their breasts and maybe, this is a huge stretch, the possibility of breast cancer. no one has proved this. if you take soy, take federal mentioned soy and small amount. i don't want pregnant women to take this because it can be i echo a few points, the omega acids are shown for be a negative for soy. a positive for soy, there was a study in the journal of menopause this past year that showed women that took soy had a

decrease in the symptoms the viewers talking about, hot flashes. i would argue if you have hot flashes and nothing else is working and this,s would for a year or two or three, maybe it is okay but the breast cancer stuff david is talking about, i was compressed with that information. it does look like there is an increase amount of estrogen receptors that can increase the risk of what comes before breast cancer. on the one side you have the risk possibly of more breast cancer and on the other side if nothing else works this may work. >> don't take too much. >> maybe eat edamame. >> a small amount is good because there is a lot of vitamin b1 and b-2 and potassium and magazine need medium but the key is "small amounts." >> a surgeon in colorado now among the first in the country

to offer knee imlaboratories made from a -- implanted made from a 3-d printer and why it promises to improve the lives of so many patients. stick around for that. huh, fifteen minutes could save you fifteen percent or more on car insurance. everybody knows that. well, did you know words really can hurt you?

what...? jesse don't go! jesse...no! i'm sorry daisy, but i'm a loner. and a loner gotta be alone. heee yawww! geico. fifteen minutes could save you fifteen percent or more. jesse? get to the terminal across town. are all the green lights you?l. the 4:51 is leaving at 4:51. ♪ they cut the power. it'll fix itself. power's back on. quick thinking traffic lights and self correcting power grids make the world predictable. thrillingly predictable.

>> it is called a revolutionary option for patients requiring total knee replacement created with the help of 3-d printing, a new take on a common procedure which promised less time in the operating room and less time in recovery. it sounds great if you can explain how it works. >> the quicker recovery is what we all want. let me tell you how it works, a company confirs has f.d.a. approval and 600,000 total knee replacements, the number one point to be replaced. surfs will have to choose from several different types of knee but they will not always be able to fit you perfectly with a quarter to a third of the time they find out after the fact it is not a perfect fit. this is how it works: they take a cat scan image and make a wax

model with a digital image that is to the keeping of your knee. with the wax model they build the knee replacement to fit that model. what they put in the body is an identical dimension of what they are taking out. they are removing part of the bone and it looks like a wood shop. >> they don't take them off the shelf? >> they take them off the shelf and make a few different versions. >> if it fits they say okay. >> exactly. >> now all orthopedic surgeons in the country...this is how the accidentists put the implants if areas. custom tailored surgery, patient-specific type. this is what is exciting about surgery of the future, not everyone is going to have the same kind of implants. you take it off the shelf, the surgeon has to taylor it and there is a lot of shopping and cutting and designing to fit the knee and now with 3-d printing

they take the cat scan, they can find the map of that particular knee, your knee structure is different than my. certainly different from dr. siegel. they basically take that model and give it to this 3-d printing and that is the new knee joint. >> are this other things? >> we are taking the stem cells and creating new valves, new heart valves, new bones, et cetera. i am excited about this. it will open a patient-tailored type of surgery. >> body organs, i believe, as well, in the next few years. >> you have seen some of my prostate surgeries, they can do the same. >> they can make a whole new you. >> he is perfect as he is. >> can you imagine another dr. siegel out there.

it can replace surgery. >> fantastic. >> the mediterranean diet. >> thanks so much. >> on the buzz beater, the architect of obamacare saying the law was designed to pass because of the american's public stupidity and ignored by the "new york times" and the mainstream media. what gives? >> you don't get the news. if it goes against the liberal orthodox. this is proof, absolute proof. >> if it were a republican... the anchor who says cnbc challenged her when she challenged the selling of obamacare. >> i was called to management and told i was
