mubarak has denied all of those charges. one week from today sunday, there we go, the diamond jubilee. royal watchers with an historic occasion as queen elizabeth marks 60 years on the throne. her diamond jubilee celebration kicks off with a special flotilla and cnn will bring you the whole event live. we'll have much more at the top of the hour when cnn sunday morning continues, but, first, sanjay gupta m.d. begins right now. a lot of people are asking questions, and today i'm going try to answer some of the bigger ones. what you need to know, first of all, about that flesh eating bacteria. also, why one in three schools have become so bad they make children sick, and one of the filthiest spots with the most germs in your workplace. we're looking at this

controversial new position. the task force which says men should not be screened routinely for the psa test. as you probably know by now, it it's a simple blood test, and it's the only screen test for prostate cancer, which is the second leading cause of cancer deaths in men. the american cancer society supports these new guidelines and other groups do not. i'm here today with dr. otis sprawly from the american cancer society and also dr. scott miller, who says not screening could cost lives. we'll get to that denit bait, but, first, i want to explain some of the reasoning behind the new recommendations. basically they say that more people could end up harmed by unneeded treatment after a worrisome psa result than are saved by early detection. now, we talk about these numbers a lot, but it's not an abstract number. i want to bring in dr. jeffrey stark, a pediatrician in houston who last year became a prostate cancer patient himself. welcome back. hanks for joining us. as i said, there's real stories behind a lot of these numbers.

you were concerned, as many men are, about prostate cancer. you have a family history. what happened after that? >> well, several years ago i had a slight rise in my psa screening, and i had a biopsy done that showed everything was okay. i had more testing done after that and had a very slight rise many my psa, and theureologist wanted to do another buy opsy that i had done a year ago february, and i got extremely sick. even though i had antibiotics, i got septic, severe bacterial infection, high fever, shaky, chills. my blood blood pressure went dangerously low. my circulation shut down, and i was hospitalized for four days. >> you're okay now, obviously. was that all resolved? >> i'm fine. actually, i had a little heart rhythm problem afterwards as well, but now everything is fine. i don't have prostate cancer. >> back to the second doctor, dr. miller, you hear a story like this, and this is one case. there are lots of multiple cases.

what do you think as a urologist? he got harmed potentially by this by getting the buy opsy and his heart problem. department have prostate cancer. how big a concern is that? >> it's a big concern. i'm very concerned, and i sympathize with dr. stark's position, his perspective on it, and i'm happy that he is fully recovered and he doesn't have prostate cancer, but that is a complication. that would be a result with complications over the psa blood test. it's clearly -- >> what do you tell your patients in temz of the beginning of the whole process? how many times do you say we're getting a psa test. how can you talk them through? >> first, i tell them what the psa test is for. it's to screen for cancer. something diagnosed for prostate cancer. we need other testing done, and that's the concern. the psa blood test can vary depending on a patient's situation.

depending on whether they're old, young, what their risk factors are for prostate cancer. it will be one factor many terms of buy opsies. >> doctor in your position, you have written about it and daukd about it quite a bit in american cancer society supports these new guidelines, what do you think the role of psa test is? it sounds like people want to abolish it. >> we need new screening into the physician-patient relationship where physicians look at a particular patient and say these are the known harms, these are the possible benefits. there are a lot of things that there may be some benefit. do you want to get screened and let the patient decide. >> look, as a patient, how will they make that decision? >> i think the most important thing is there has been so much you should get a prostate screening without actually explaining to people that there are harms out there. >> let's say i'm getting a test

many your office. let's just say i am. what do you tell them? >> i do practice general internal medicine. i do think that there is a point in time where the patient says, doc, i can't make a decision. can you help me or make the decision for me? i think the doc should weigh the patient's concerns and patient's risk factors and inform the patient that we don't really have good studies to show that this save lives. >> i disagree. i think there are several studies. i'm not iffing to quote statistics, but there has been a reduction in prostate cancer since psa. >> i have heard you say that, yes, symptoms should be tested. what are symptoms? >> any man who has urinary problems. i think it's reasonable to be tested. >> most people develop them. >> and maybe reasonable to test. >> let's say symptoms are urinary tract, and most people

aren't just getting tested now late. >> i'm not necessarily -- indeed there are studies to suggest that that is not the case. they can have relative connection. >> again, these are conversations men have. they said, look, i'm going to develop the symptoms which would lead to psa testing, so you're just saying wait until i get -- wait until i'm more advanced in age to get the testing, and that potentially could be also letting cancer run amok. let me let dr. miller weigh in. what are you going to do now? about your practice. >> may i respond to the question? i do think they should still have symptoms that need to be evaluated and probably including the psa test. prostate cancer often is not curable once you have symptoms from the prostate cancer. >> keep in mind i think you'll agree with this that men who are over the age of 50, especially, should know the mn harms associated with psa screening

and it's really not the -- it's the treatment associated with the screening that causes the harms. along with potential benefits. >> dr. stark, you've been listening into this conversation. look, would you do it again given all that you know how and all that you just heard? >> i teach students and reinforce the principle that i teach them, and that is when a person without significant risk factors is it screened for any kind of test, a positive result and potentially much more likely to be a false positive and if that false positive leads to an invasive treatment or procedure being done, it can lead to consequences, and, unfortunately, in my case those consequences occurred. >> well, i'm glad you are doing well. i hope we tried to make this a little clearer. it is confuse, but it's fun to dive into these issues every now and then. >> we'll keep talking about it, i think. >> coming up, what to do when a child's school is making him or her sick.

we cover stories about

health danksz. just recently i was amazed to learn that schools can potentially be a danger spot. in fact, get this. one school in three has air quality that is so bad by e.p.a. standards that can literally make children sick. some set of parents dent wait for summer vacation. they said their kids are staying home until things get better. >> in picturesque winston, connecticut, a 250-year-old new england town. a typical school day at hinsdale elementary, but one-fourth grader matthew won't be there this morning. or any morning. >> now, if you look at him, do you think he is going to be -- >> matthew's mother, an elementary schoolteacher, is homeschooling their son this year. >> when he was out of school, he was well, and when he was in school, he became ill. last year was by far his worst

year. he missed more than 50 days of school. >> mold at hinsdale, she says, was making her son sick. >> this bag represents most of the medications that matthew was on last year. this is zopinax and zyrithromayacin. when he left school, he left all of this behind him. this is garbage. >> this is actually a zero. >> alexandria's parents pulled her from school this fall after a persistent cough wouldn't go away. her father, paul, is on the school board at the time. >> she was put on nebraska lieser, steroids, and other medication. since she's been at parochial school, she hasn't been on any of those. >> reporter: the school district spends $16,000 this fall to get rid of the mold at hinsdale, and the board is now trying to decide whether to close the school temporarily to replace a leaky roof and make other

repairs. only about 20% to 30% of the population is susceptible to indoor air problems like mold or dust, but for those who are, the symptoms get increasingly severe. in fairfield, connecticut, so many students and teachers were getting sick with respiratory problems that officials decided to tear down mckinley elementary ask start from scratch. the school was riddled with mold. >> i started to get sick the second when they put me in the basement classroom. >> reporter: mckinley special ed teacher at all for 23 years before she became permanently disabled with a serious lung condition called chronic obstructive pulmonary disease. >> there are three levels. mild, moderate, severe. because i've lost 50% of my lung capacity, i'm considered a moderate cobd person. i've also never had a pain-free day since then because i have chronic pain.

i have muscle spasms. >> you can see another source of spain for joe ellen. if you ask her if she misses teaching. >> i'm sorry. that's a really loaded question for someone who has been forced to leave the profession when they didn't want to. i'm sorry. >> if you think connecticut is somehow unique, consider this. a 2010 survey of school nurses nationally found 40% sxirn and staff sickened by their school environment. not all school districts have the money to fix the problem. here at southern middle school in redding, pennsylvania, concerns about air quality los the basement gym. and mold is visible in the computer lab. >> we see some colonies. probably two, three different kinds of mold here. >> and take a look upstairs.

>> when it rains heavily, the water actually rains into the room. what we do is we use buckets, these trash cans, and we collect the water. >> it's raining outside and inside. >> a teacher shot this video. >> what about mold? >> one of the residual effects to the water would be mold. >> drew miles is acting superintendent of redding schools. he has seen the video, and he says there's no money to replace that roof. >> the buildings continue to deteriorate, and we only have a small amount of dollars to spread to do just some minimal things like new roofing. >> there are some people who would say this would never happen in my school. >> lily of the national education association, which is the largest teachers union agreed to meet me in redding, pennsylvania. >> how big a problem would you say indoor air quality is to a student's health?

>> right now the last estimates said about one-third of our schools. about one-third of our schools have some kind of problem that causes respiratory problems many children. >> that's remarkable. >> it's horrific. it is horrific. >> would you send your kid to this school? >> to this school? would i send my child to this school? for the quality of education that i believe that these teachers can provide and the principal will demand, yes. from a facilities standpoint, if i had mother option i would exercise it. >> you're the superintendent. people are going to be surprised because you're the guy who they're going to say, look, make it the school you want to send your own kid to. you can't do that. >> i can't with the financial means that i have now. >> i'll tell you, the acting superintendent you just saw, he

was fired this spring after that story first aired on cnn, and just this month the school board said they're laying off more than 10% of the teachers in redding. no mention of repairs to the school. now, if you as a parent want to look for signs of trouble in your child's own school, poor air quality in particular, one red flag is going to be mold. you just saw it there. you might see it specifically on the ceiling and look for thick dust on top of lockers or on the floor. one that you might not think of, cars and buses idling outside. the exhaust fumes can get inside the school through vents and doors. if you see these types of things, sound the alarm. also, stay right there. after a break, we'll take on flesh-eating bacteria. stay with us.

this actually measures the amount of acp on the surface. >> what they're doing is looking for the spot in our office that's most contaminated with unwanted bacteria. you will see what they found in a few minutes. first, something more serious. something that has this horror sounding name, flesh eating bacteria. i want to tell you what you need to know. first of all, there's no evidence there are more cases than unusual this year, but there's a lot more attention. also, there are different types. some rare, like the one that attacked aimee copeland in georgia. other flesh eating infections are caused by common bacteria that get into a more susceptible person, and then they really do eat through fat and muscle tissue. you get extreme inflammation, swelling, pain, often fever. don't be paranoid, but i suggest if you have a cut and the pain seems greater than it should for the size of the cut or if the pain is growing rapidly or looks worse, don't ignore it. any infection should be treated

and some, as we've seen now, are devastating. anyone who has had an infection like that faces a long road back. you might find some inspiration here. a young man, a newly minted nba in some ways, no different from most new graduates, he's worried about finding a job. but if you think that's tough for him, consider this journey. >> reporter: in 2004 his family couldn't have been more proud because he was coming to america to purdue university to complete his degree in computer engineering. just a month from graduation, however, his life changed forever. his neighbor two floors below intentionally set a fire with his wife and child still inside. >> by the time my roommate and i woke up, the whole apartment was on fire. >> he and his roommate tried to escape, but they couldn't. >> my roommate collapsed in front of me, and i started running down the stairs. >> he only made it down a few

steps before he collapsed. a fireman found him still alive but on the way to the hospital he could hear paramedics talking about how badly he had been burned. >> at that moment he was think being my family, what i had come here for, to get a good education, and now this guy is saying i don't have a chance to survive and i passed out and then i woke up in university of chicago burn unit after four months of induced coma. >> rana had burns over 95% of his body. so far he's had 54 operations. but he didn't give up. and he credits three people for his survival. >> my father, my mother, and my occupational therapist, shannon hendrix. >> reporter: he says his father saved every hard-earned penny so he could get an education. >> my mother always kept on telling me have some faith and keep your eyes on the goal. >> reporter: and then there's shannon, whom he calls his guardian angel. he says she's gone way beyond

the duties as an occupational therapist making it her mission to help in any way she could. >> on top of my therapy, she would take me to church every sunday. i think that was the only thing that kept me from going crazy because as a 22-year-old, i was living in a nursing home and it was really, really depressing. >> reporter: his biggest accomplishment so far, getting his mba. i recently graduated with the highest honors. >> i'm still happy that, you know, i can live an independent life and now, you know, i have gotten my mba and hopefully i will get a job soon and, you know, have a good life. >> a lot of people are throughout rooting for him as well. news headlines are minutes away, but next we're looking for the most germ-ridden spot in anybody's office. we'll show you. ♪ if loving you is wrong ♪ i don't wanna be right
