In shape in school preventing back pain with exercise in the classroom a shunt in the skull the operation that can cure one form of dementia. And a sting on the skin what attracts mosquitos, and how to keep them at bay. One in three cases of cancer is skin cancer. Thats a lot. But theres some good news. Since doctors dont need xrays or fancy lab tests to examine your skin, tumors can be detected at an early stage and treated. When it comes to skin cancer, most people think of malignant melanoma. But there are other types of carcinoma to watch out for. Of course, prevention is always better than needing a cure. Protecting yourself means shielding your skin from too much sun. And regular visits to the doctor for screening. 43yearold Susanne Hoffmann regularly visits her dermatologist to have her moles looked at. Over the years, shes had a few removed. Seven years ago, she had her first cancer scare. I found something that looked suspicious. It didnt look like a normal liver spot. So i went to my dermatologist and had him examine it. It turned out to be nonmelanoma skin cancer. Nonmelanoma skin cancer is usally caused by too much exposure to the sun. It tends to form on the surface of the skin, around the nose, the lips or the forehead. I do love the sun and i always did. In the past we werent aware of the risks of sunbathing. When we were younger wed go to the outdoor Swimming Pool and wed never apply sunscreen. Dermatologist Christiane Bayerl sees a lot of patients with various types of nonmelanoma skin cancer. Basal cell carcinoma appears as a red patch with dilated blood vessels and often a raised bump. It might bleed. Squamous cell carcinoma appears as an ulcerated lesion. The tumour that Susanne Hoffmann discovered was a basal cell carcinoma. It was surgically removed the standard treatment for nonmelanoma skin cancer. Two months ago, she had another removed. But her regular checkups also revealed a malignant melanoma. It was quite a shock. I was used to treating the nonmelanoma skin cancer. But being diagnosed with a malignant melanoma is something else. Becoming a cancer patient takes its toll. Susanne hoffmanns malignant melanoma was surgically removed before it spread. Basal cell carcinoma never spreads and squamous cell carcinoma is only likely to spread after decades. Then it might spread to the lymph nodes. Susanne hoffmann is now ultrastrict about applying sunscreen. She also uses a moisturizer and face powder with factor iv protection. She still enjoys the sunshine but makes sure she stays in the shade. She misses sunbathing but now that shes experienced the consequences firsthand, shes not taking any risks. Joining me in the studio is dr. Claas ulrich, a skin cancer specialist from the charite clinic here in berlin. Thanks for joining us. We just saw that relatively young people can also contract skin cancer. Which groups are most in danger . Well, of course, it is mostly the fair skinned population, but of course, those who have already had a lot of uv exposure in their life or those who live in sunny environments like australia, new zealand, south africa, or even the central area of the mediterranean. And, of course, everybody who is, so to say, defenseless. What about people with workers skin tones. Are they prone to skin cancer . Can they even get skin cancer . They can, but that is very, very rare. In black people from the Central Africa area, for example, ella noma is only very rarely found on the palms and soles melanoma is only very rarely found on the palms and soles, which are not pigmented. The nonmelanoma is a sandpaper type feeling. In the black skin cancer, the melanoma, you should recognize any change of the pigment from brownish to blackish, whitish to reddish. Then ask a sn cancer specialist for advice. He signs i theres ay interesting role called the Ugly Duckling role from the fairy. The black duck was the one that was not liked. That translates to if you have a lot of lack moles, the softer colored ones are the most dangerous ones and vice versa. Its more like the exception to the rule. Absolutely. We have a viewer question. Margot bachholz from chile writes that she spent a lot of time tanning when she was young, though she didnt usually get a sunburn. Shes now 64, and is beginning to get red spots on her face, and also has many dry areas there, though they dont itch and she doesnt have other symptoms. She wants to know whether she did permanent damage back then that is only showing up now . Sooner or later, that can become dangerous for her, and she should seek advice from a dermatologist for therapy. Ok, good. Zakir khan from pakistan my question is, is sun all the time in the day dangerous for skin or it might be useful for it as well, i mean early in the morning, when its intensity is low, does it have any good effect on the skin . The worst is the midday sun because that is extremely rich in ultraviolet radiation of the b type. Ok, we will see each other again in just a moment. A dark tan has long been considered a mark of health and beauty, at least here in germany. That is strange since tanning is actually the skins attempt to limit the cell damage caused by uv rays. When the skin is exposed to ultraviolet rays, the cells on the surface of the skin start to produce a dark pigment called melanin. This makes the skin appear darker and acts as a kind of natural sunscreen to protect the bodys dna against harmful uv rays. But the protective role played by melanin is limited. So anyone whose skin is exposed to the sun for any length of time should always use sunscreen. Dr ulrich what about the skins natural Protection System . When should i use sunblock . Whenever the challenges for the skin would be too big for its natural defense. If you go to a more sunny environment or go out mountaineering on the weekend or or a water sport, you should consider additional sunblock for your skin. One guest wants to know about the spf protection factor and what they mean. The ef spf are grades of Sun Protection and basically tell you in which timeframe the sunburn individually is delayed, compared to milder or softer version. Can you even use those to get your skin a little bit lighter . Nilutpal karmakar from india what are the measures we can take so that our skin doesnt turn dark under the sun . Photo blocking or a sun blocking is a popular thing to get your skin lighter and is used in asia. You should also consider to mind the midday sun completely. If i take a sunblock, how long can i stay in the sun with maximum protection . Basically, it depends a little bit on what part of the world you are. Even 100 block lets do a couple of uv rays, so that is a very individual thing, but never abuse photo protection in order to spend all day in the sun. Does it help if i repetitively cream myself with the bloc . That puts on additional protection, but you will never have a 100 shield. What about zinc in sunblock . A guest from uruguay wants to know if the zinc oxide in sunblock is helpful . It is a relatively safe and oldfashioned protection. It is safe, but cosmetically not so nice for most people because they are afraid of the whitening effect of oldfashioned sunscreen. Because i look pale. Yes. In europe, we like to have transparent photo protection. Other alternatives to those sunblock techniques like textile techniques . I think textiles should come before Additional Photo protection is creamed on. A hat, a longsleeved shirt or long trouser, those are basically the pillars of photo protection. And behavior mind the lunchtime sun. Is the color of the textile protection important . Black partly is better than white, but most important is the advert of the textile. If you are the thicker one or a special photo protected textile, and theres brandnew labels developed all over the world at the moment, that gives you additional security. Ok, and our viewer from our viewer kadri haapoja from estonia asks are there foods that can help protect you beta carotins . Antioxidantrichfood, meaning fruits, and what we call the mediterranean diet, meaning tomatoes, paprika. Sums like that as an addon but does not save you completely. Dr claas ulrich, thanks for joining us on in good shape. Do you know what i like most about talking with experts here on in good shape . Your input so please keep those questions coming in. Especially if you have one about this topic, which will be covered in an upcoming show well be talking about loss of eyesight in an upcoming show. It can happen suddenly or it can happen gradually. Which conditions cause it . And what can be done to prevent it from happening . If you have any questions, email us at ingoodshape dw. De. The keyword is eyes and the closing date is july 15th. Youll find our Mailing Address on our website. Have you ever missed a couple of days at work because of lower back pain . Here in germany, backache has a major financial impact. A big German Insurance Company did the math about 40 million working days are lost in in the country every year due to this condition alone. And back pain doesnt just affect construction workers or people who perform heavy manual labor. Long hours of sitting at a desk can also pose a threat to your health. And thats not true only for adults even schoolchildren can adults develop back problems. Barbel ehrig teaches fifth graders. Unlike many of her colleagues, she doesnt insist that her students sit still. Movement is good for their backs. Its important for everyone to learn to listen to their bodies to know whats good for the body and whats bad for it. These exercises arent designed just to strengthen the back. According to barbel ehrig, they improve the Students Learning abilities. Its worth interrupting class for a few minutes of activity. It definitely helps. It wakes you up and improves your concentration so you can work longer. Sitting at a desk for long stretches isnt healthy. Barbel ehrig believes that parents also have to do their bit to get their kids moving. I dont neccessarily mean sports. Children should be outside playing catch or hide and seek or on their scooters. Barbel ehrig is in charge of the health and fitness issues at her school. She also makes sure the students schoolbags arent too heavy. Thats another cause of back problems. Experts say the weight of a schoolbag shouldnt exceed 10 to 15 percent of the students body weight. In sports, these eleventh graders are learning how important it is to look after their bodies and not put their backs under undue stress. Now sit down gradually as though there were a bar stool behind you but its incredibly hot, so you stand up again. The girls enjoy the class a lot. It feels good its a different way of moving. Its good to do something thats useful. Normally you dont really think about how you sit. Or how you lift. Barbel ehrig tells her students how to make sure theyre not overtaxing their backs with wrong movements. You can teach basketball or football or the high jump, but thats not the sort of thing that changes the way people move every day. I have to change the way they think so that they incorporate activity into their day to day lives. And thats exactly whats barbel ehrig does with her students. More and more frequently, i see patients in my office with memory problems. Thats of course partly due to the fact that people are living longer, and the average patient is older. But that doesnt comfort people who are beginning to lose their memory. Thats always scary. Many of my patients and their loved ones worry about dementia. However, impaired brain function in the elderly is not always necessarily due to alzheimers. Sometimes a disease called normal pressure hydrocephalus can cause it. And this can be treated with amazing results. Dieter schroder is in his early 70s. He suffers from a range of problems related to old age. He has difficulty walking, for example. But today hes having tests done to see if the cause is an underlying condition that could be treated. His wife christine was getting fed up. Once when the weather was nice we wanted to go out for a walk. We thought wed just go around the block, very slowly. But wed only gone half way when it got so bad that the last few meters were agony. Forgetfulness is another problem. Sometimes when were chatting and my wife says something, i completely forget what shes said. She always says, but i just told you but i simply cant remember. And i remember less every day. Its a terrible problem and it worries me a lot. His neurologist suspects that Dieter Schroder is suffering from normal pressure hydrocephalus nph . This is a type of brain malfunction caused by excessive production of cerebrospinal fluid. It can cause lasting damage. Dieter schroder is having tests done in the hospital. Neurosurgeon Alexander Konig asks him if he has the main symptoms of the condition these are gait disturbance; forgetfulness, inattention, and incontinence. Dieter schroder confirms that he suffers from all these problems. With patients suffering from normal pressure hydrocephalus, the pressure of the cerebrospinal fluid doesnt remain constant for 24 hours a day. If the condition is untreated for months or years it can cause secondary damage to the brain. An mri can help rule out other conditions. The dark patches show that neural water has collected in the brains chambers, the ventricles. This can cause forgetfulness, which is the next thing the dotor tests with his patient. The doctor also checks Dieter Schroders gait. He is taking steps that are about half as long as his foot. This is fairly typical and a lumbar puncture provides the most conclusive evidence of nph. This involves taking a sample of neural fluid from the canal of the spinal cord. A lumbar puncture entails collecting cerebrospinal fluid over a period of three days. This has to happen in a hospital. It allows doctors to reach a conclusive diagnosis. If the symptoms start to improve, a valve can be inserted into the skullcap which regulates pressure to the brain. This is whats called a cerebral shunt. The basic principle is that surplus neural fluid from the brain chambers is directed to the adbominal cavities. The technical term we use is ventriculoperitoneal shunt. The treatment can reverse the symptoms and restore normal functioning. This method brings about a noticeable improvement to the patients gait. It becomes less unsteady, they can take bigger steps and there is also an improvement in cognitive deficits such as loss of memory as well as incontinence problems. In a matter of hours, the redirected neural fluid is having a positive effect on Dieter Schroder. Theres a very noticeable improvement in his gait. Hes taking half as many steps and his steps are much longer. This confirms the normal pressure hydrocephalus diagnosis in our opinion. The only therapy is operative. Thats the course of action we recommend in this case. The couple decide that Dieter Schroder will definitely opt for a cerebral shunt. I hope that ill feel better after the surgery and that ill be able to walk again more normally. Thats what were aiming for and we see this as the only option. After surgery, taking a walk around the block should no longer pose a problem to Dieter Schroder. I hate being bitten by mosquitos, even though they dont carry dangerous diseases here in germany. The itching and burning a bite causes is really annoying. But in many regions of the world, the insect can do much worse. Mosquitos can transmit serious pathogens like those that cause malaria or yellow fever. In fact, well over a Million People still die from those two diseases every year. Reason enough to take a closer look at this pest, and how to protect yourself from it. Its a Beautiful Day and everyones outdoors. Theres just one problem. Mosquitos also love the warm weather. And they can really spoil the fun. Like other insects, they feed on plant juices. But they also need human blood to reproduce. It contains proteins that the female of the species requires for egg production. Its a myth that mosquitoes prefer sweet blood. The greatest attractant to mosquitos is carbon dioxide. Ammonia and lactic acid in human sweat lead them to their victims. It remains unclear why some people are more likely to be bitten by mosquitos than others. Dutch research on malaria mosquitos suggests that it migt have something to do with bacteria. The test persons who get bitten the least have a greater variety of bacteria on their skin, including large quantities of whats called pseudomonas bacteria. It seems mosquitos dont like the way the bacteria smells. The discovery could help in the development of n n mosquito repellents. When mosquitos bite humans, they know exactly what theyre doing. They plan their attack carefully. They tend to be especialy active at night and dont bite any old place. When a mosquito lands on your skin it sticks its proboscis into you. Its anticoagulant saliva contains proteins that prevent your blood from clotting. It then sucks your blood into its abdomen. How can you prevent mosquitoes from biting you . Mosquitoes lay their eggs in water so its a good idea to keep fresh or stagnant water in your garden covered up. Many insecticides are effective but contain chemicals that can be harmful, so should be used sparingly. Fragrance lamps, on the other hand, tend not to be very effective at all. While uv lamps kill other, harmless insects. Taking a shower before you go to bed can help given that mosquitos are attracted to sweat. Mosquito repellent creams or sprays can also prove effective. Tests show that the most effective ones are those that contain icaridin or deet. But deet is known to have damaging effects on the nervous system. It should only be used in places where mosquitos carry dengue fever or malaria. The safest way to prevent bug bites is to sleep under a mosquito net. Or kill them before they get to you. Hard to believe, but thats all for today. If youd like to share any special tips on how to deal with mosquitos, please dont forget that you can always friend us on our bilingual facebookpage. That wraps it up. Well be back next week same time, same place. I look forward to it. Until then, always remember to try to stay in good shape. Captioned by the National Captioning Institute www.
