>>. >> eric: time for sunday house calls. joining is dr. mark siegle. associate professor of medicine and author of the inner pulse. >> jamie: andled is david samadi. chief of robots at mount sinai malmedical center. great to have you here. er where i go people talk about

this segment. there is new hope for those that are visually impaired. the fda approved a brand-new item? >> right now we are use foorg a condition called retinitis pigmentosa where the lighted cells in their eyes in the retina are not working. it's congenital. you get it when you are born. sites have been -- scientists have been trying to figure a way around it but they are icing camera technology. they are using the camera. department of energy has been involved in this since 2002. it's called argus. they have gone through three prototypes and argus one, two and three and they put a video camera on a pair of glasses. video camera sends impulses to a

computer chip that sends these impulses on to the eye where electrodes are implanted on the retina. this is the hard part. the electrodes converted into signals that the brain understands. that has required all the research. how does the eye do that. how does the eye converts them. this device has been able to do that. third one, second one, argus 2 has been approved. they are studying it and found to help people to differentiate objects maybe preliminary things like letters. it's not perfect but the next one, which is going to use 200 electrodes it will be finer. so people that are blind will be able to perform daily functions again. >> jamie: it sounds like a miracle. do ophthalmologists be able to

do the implantation? >> it will cost about hundred thousand dollars. only 30 have been done and approved in europe and we got the approval by the fda. i wanted people to understand what this is about. when you see something, the images have to be translated through an electric pulse. that is what the retina does. it's a camera and kodak films, that is the film. it takes the image and translates into a pulse and goes through your nerves and brain gets back to the image. that is how we see. this is huge step forward. there is a lot of research from columbia on genetic studies and 50 gene knew teigsz and stem cell going in research and then came the implant. what it really is, it simulates what the eye does, it translates

into computer and shifts it to the nerve. big question comes in, do we have kidney transplant and corneal transplant for the eye. why can't we do an eye transplant? the answer is it's almost impossible because there are so many nerves, millions of nerves are involved so we can't do it. it's a big step. they can see street signs, they can see the door when they open. the part of the problem is they lose their night blindness first and then they lose the periphery and then they lose the center. that is different than macular degeneration. >> jamie: that sounds like lasik surgery but you need glasses at night. >> david mentioned stem cells. in san francisco and harvard, ongoing studies using stem cells

where you regenerate parts. macular degeneration that we sbeok about, that is another possible use for this. you have a hundred thousand people with retinitis bigmentosa and millions but the chip and electrodes keep getting smaller and smaller. it's like robotic surgery. >> jamie: this is very exciting. we will keep our audience when it will be available. >> eric: take vitamin c pills? researches are finding out that men to take vitamin c are higher risk for developing kidney stones. you take vitamin c and now you are going to get kidney stones? >> look a lot of people during the wintertime they take vitamin c. as a prevention for getting cold

and more is better which is a big mistake. in this particular study that was published in jama, they found if you take a thousand milligrams of vitamin c double the risk of getting kidney stones. the majority we see is calcium is oxalate and i will also tell you one of highest risk is dehydration. when you are not drinking enough water that is highest risk. if you have a family history, if you have a not drinking enough, you have to be careful about how much vitamin c you need. all you need is 90 milligrams a day. the other source is tea, it has a lot of oxalates and spinach. >> eric: how about popping vitamin c pills? >> i don't have time for taking all these other invite manipulates. if you have a good balanced diet

fruits and vegetables, one multivitamin is enough. >> eric: we got the vitamin c on the counter? >> i looked this up as part of the study, multivitd minimum users there was no increased use of kidney stone. it's only a little bit. the key here, the swedes tend to take a thousand milligrams. it appears to double your risk of kidney stones if you have never had one. this is especially problematic for people who have had kidney stones. people you want to watch the vitamin c they take have known kidney stones. that group is higher risk. multi vitamins are fine, you are

taking a supplement i'm not wild about it but less than 500 milligrams. what is important, about vitamin c, you need it to prevent heart disease and prevention of anemia, repair of the muscles. we're not saying don't take it but more is not better. >> jamie: moderation. >> drink a lot of fluids. >> jamie: next time you sit down for a meal, surprising new research linking salt, but it could affect your life expectancy. we'll go to that next. >> eric: go to foxnews.com/sundayhouse calls and we're taking questions and answer some of them on the air. . otherworldly things. but there are some things i've never seen before. this ge jet engine can understand

>>. >> jamie: welcome back. i understand french-fries taste better with salt but there is new researcher with intake of salt how long you live. you could save half million american lives over the next decade. >> first of all this study is mathematical model they took a lot of information and put it together to make estimates. if you decrease salt what would happen. most americans average about 3.6 grams of salt per day. all recommendations they want us to have about 2 grams a day. that is lot less. this study estimated a mathematical model, over a decade we decreased our salt intake by 40% it would save

500,000 lives. it's about one teaspoon. here is how this works. the salt shaker is about 25% of the salt we get but most of salt we get -- here is why i'm optimistic we could decrease by 40%. salt has been associated directly with heart disease with high blood pressure w strokes. i believe the research on this. how do we do it? the salt shaker is 25% but most of it is i had hidden in soups and breads and cereals. if we shifted over to more fruits and vegetables and more grains and less cereals and less processed foods we would make up that 40%. >> jamie: it tastes so good. >> it's because of the salt and you can get used to it.

>> eric: you have to look at the amount of sodium in the cans is unbelievable. >> jamie: are these alternatives. they do make low sodium have a rights, is that enough? >> i'm not sure. as mark mentioned we are diagnose double the dose of salt in our diet and healthy people need to watch out. salt, we need salt to survive. that is extremely important but too much is not good for you. it absorbs the water and pressure in vessels is known as high blood pressure and heart disease. but the studies on this, it's very confusing and very conflicting. we don't have the correct answer. what we know is if you are over the age of 51 and kidney disease and heart disease if you are african-american you have to stick to 1500 milligrams of salt which is half a teaspoon. highest number you can go about 2300. if you have a cheeseburger with french-fries that 200, if you

add ketchup that is 1500. most of times you think you would get salt, potato chips and soda but it's really the soup and sauce and everything else. i tell my patients to stay away from sugar, stay away from white flour and finally cocaine. >> jamie: thank goodness. >> eric: don't put salt on your food. you don't need to add salt. >> your restaurants will be loaded with it. >> eric: no salt on the food. coming up, you know about adhd, the numbers have been rising dramatically over the last decade. medication is available. new questions about exactly how effective the treatments are, doctors will weigh in on adhd.

>> jamie: and emotional crowd gathered for the pope's first blessing. what we can expect in the coming weeks. we'll tell you next. look, if you have copd like me, you know it can be hard to breathe, and how that feels. copd includes chronic bronchitis and emphysema. spiriva helps control my copd symptoms by keeping my airways open for 24 hours. plus, it reduces copd flare-ups. spiriva is the only once-daily inhaled copd maintenance treatment that does both. spiriva handihaler tiotropium bromide inhalation powder does not replace fast-acting inhalers for sudden symptoms. tell your doctor if you have kidney problems, glaucoma, trouble urinating, or an enlarged prostate. these may worsen with spiriva. discuss all medicines you take, even eye drops.

stop taking spiriva and seek immediate medical help if your breathing suddenly worsens, your throat or tongue swells, you get hives, vision changes or eye pain, or problems passing urine. other side effects include dry mouth and constipation. nothing can reverse copd spiriva helps me breathe better.

>>. >> eric: back to sunday house calls. big issue, adhd, one of studies and questions about the treatment. doctor, you hear about this all the time. what does the study says? >> they looked at patients and followed them for about six years. what they found out is nine out of ten kids really didn't do well with medication and the medication doesn't work. my take on this after reading all this, this disease, adhd is overdiagnosed and overtreated and lots of these kids are falling into that category. that may or may not to be there. we recognize it better and we are diagnosing more and you can see from the last decade we have 21% increase in the diagnosis of this. the medication, the diagnosis

followed by treatment or medication. this is one disease that we can really spend time -- i know it sounds like a broken record -- but behavioral modification is lot more powerful than writing a prescription and giving it to them. it starts from parenting, it doesn't mean yelling and screaming them and punishing them. there are specific guidelines to how to go about this. go clean your room. if you go back and the kid is not concentrating, give them a positive response, positive reward type of thing. if they do something great, give them a reward. if they are not doing well, there is a time out and consequences. if you follow that and spend time with them and be a role model, plus the classroom you can take care of disease. >> eric: we hear a lot they will write the prescriptions without diagnosing it? >> i agree with the doctor about

this. it tends to be overdiagnosed but the wrong people are picking out a school teacher may not much know about it and may not get to the right experts. they may have a diagnosis that stigmatizes them. but i this i it's a real condition. restlessness and hyperactivity in some chin. some will outgrow it. some won't. i think mark riddle who is the lead author of this who i emailed, he pointed out the limitations of his own study. we can't give one group medication and other no medication and see what does better. how do you know it's right thing to do? one thing i agreed on him is a team approach is probably the good idea but it has to be the right team. who is helping the child?

the problem with medication they may score better on tests, does that mean the medication is the right thing. >> eric: what do you do if you are a parent? >> these kids are really smart. if you have to guide to them in the right direction. if it is done correctly they turn out to be superstars. if it is not guided well, they are drug addictions. you have to be careful. the team approach that mark is talking about having the right doctors or parents and teachers that work well totaling to contain this is the way to go. >> eric: your vision? >> i think the main thing here is not go overboard with this. the main pointed of the study a lot of symptoms are persistent. the point they are trying to make a hopkins, the symptoms may not go away quickly. the kids need the supported they need. >> eric: talk to your doctor, of

course. >> jamie: please come back and tell us step by step how you build the team. we would love to help folks that way. and lots of folks got away from the presidents' day weekend but there are health hazards with all that traveling. what you need to know coming up. i have a cold, and i took nyquil, but i'm still stubbed up.
