Skin Color Inheritance

Dear Dr. Warren: My husband and I are planning to have another baby. It would be baby #3. I am white and my husband is hispanic. He doesn't really have such a dark complextion. He can pass for an Italian. My first child has a very light complextion. My second child is a shade darker than my husband. What are the possiblilites that my third child will have a fair complextion? My husbands immediate family basically all have a fair complextion. His mom has a little bit of a darker complextion like himself. But again my son seems to have a darker complextion than my husband. I don't know, I guess it might be in my husbands genes to produce darker children. But when my son was born we were kind of surprised on how dark he was in comparison to my husband. Another question would be is can my third child be even darker than my son. It really is not such a big issue. But it is a little bit of a concern to me. If you can e-mail me back with an answer as soon as possible, it would be appreciated.

-C

Dear C: Skin color is inherited in a complex manner; however dark skin is generally the dominant trait so that if one parent has dark skin, most of the children will have darker skin than the light skinned parent and lighter skin than the dark skinned parent. Assuming, for the sake of simplicity, that skin color is controlled by just one gene, since your husband has some light skinned relatives and you have had one light skinned child, there is approximately a 25% chance that the child will be darker than his father and a 25% chance the child will be light skinned, with the remaining 50% falling somewhere between. I cannot tell you if the next child could possibly be darker than your darkest child, however, I can tell you that if the child is healthy, that is the most important thing. If your child is sick you will quickly see how totally unimportant color is.

Sincerely,
Dr. Warren

Jobs in Geriatrics

Good morning Dr. Warren: My name is Manuel **** and I'm a student at **** High School, and I'm currently invovled in a summer program that shows us all about the Geriatric population. The question that I wanted to ask you was what are some major jobs that are in the field of Geriatrics, and I also wanted to know what are some requirements and degrees that some of these people had to get.

-Manuel

Dear Manuel: Almost all branches of medicine deal with Geriatrics because as people age their medical needs increase. The specialties an old person is most likely to encounter are General Medicine or Geriatrics for routine care, Rehabilitation medicine to deal with the aftermath of strokes, and injuries, Oncologists to treat cancer which becomes more prevalent with age, Cardiologists to treat cardiovascular disease including heart attacks, Psychiatrists to deal with Alzheimer's disease and depression, Surgeons, Orthopedists, etc. Each specialty will require college and medical school followed by a residency of 3-5 years plus subspecialty fellowship.

Aside from the physicians who deal with the needs of old people there are careers in nursing, physical therapy, and occupational therapy. Each requires college and specialty training.

Finally, health aides often take care of the elderly's daily needs providing in home care or care in a hospital or nursing home.

Sincerely,
Dr. Warren

Speech Problem

Doctor: My wife (age 66) has a problem that at this time seems unresolvable. She has a speech impairment. Our PCP as well as a neurologist, and ent specialist can find nothing wrong with her health. She has also had an MRI which turned out negative. She has restricted movement of her tongue, thus making her speech difficult to understand. Could you perhaps have any information concerning this problem? Would you have any suggestions as to what our next step should be? It has been 5 months since the onset, and despite our attempts to solve the problem, nothing has changed. Actually the condition has worsened.

Thank You very much for your time,

-PV

Dear PV: I cannot think of something that would restrict the movement of your wife's tongue interfering with her speech, the cause of which could not be found by an ENT or neurologist, with the help of an MRI; however, since speech is the only problem, instead of consulting more doctors, consult the specialist who deals with speech. See a speech pathologist for a complete evaluation and set up a program of speech therapy to help your wife deal with the problem. If there is anything unusual causing the problem, the speech pathologist might point the physicians in the right direction.

Sincerely,
Dr. Warren

Infant Rolls on his Tummy - What to Do?

Dear Dr. Warren: I have a 13 wk old son who recently started rolling over on his tummy. We put him into his crib at night on his back and he immediately rolls over to fall asleep (he falls asleep on his own). He is able to hold his head up and slightly raise his upper body but he cannot roll back onto his back. My concern is SIDS. I know sleeping on their back does not prevent SIDS but helps limit the chance of it occurring. Before we go to bed ourselves my husband or I roll him back onto his back but in the morning he is on his tummy...I am lost as to what we should do.

Given that he is can raise his head is it safe to leave him on his tummy or should we look into some way to making him stay on his back??

Please advise

-FM

Dear FM: Once an infant has learned to turn over there is nothing you can or should do to keep him sleeping on his back. Yes, there is an increased incidence of SIDS associated with prone sleeping, but sleeping on the belly does not mean SIDS will happen. If you can turn your son back onto his back without disturbing his sleep before you go to bed yourself, then you should do it. It does not make sense to try to restrict the babies movement to keep him on his back. Somehow, I suspect that would end up causing a problem.

Sincerely,
Dr. Warren

Diarrhea

Dr. Warren: My son is 4 months old and has had diarrhea for 12 days. He is having between 10 and 12 stools a day. They are not massive to the point that they run out of his diaper, but they are not small either. He has not had a fever and has plenty of wet diapers. He is breast-fed, but gets most of it from a bottle due to my work schedule. Up until about a week before his diarrhea started, I had to give him one bottle of Isamil a day because I could not pump enough for his appetite. Now he is just on breast milk. Five days before this started, I took him to the doctor because he had run a small fever the day before. The doctor gave him amoxicillin because he had a little bit of pink in his throat and one ear. The day that he finished the amoxicillin is the day his diarrhea started. I took him in to the doctor two days ago and they said he looked fine. They said if it continued, I would need to bring him for a stool culture. Today he awoke from a nap screaming in pain and would not stop crying until he had a bowel movement. I called the doctor again and they don't seem concerned. He also shows some symptoms of teething. Also, the night that the diarrhea started, I left him with a baby sitter that fed him ice cream when he was a month old that I told not to do it again. I am very worried about him!!! Can you please help me??

Before this started, he had a bowel movement about every three or four days.

-Mr. L

Dear Mr. L: If the baby is having mostly small stools, there is little risk of dehydration as long as the baby is not vomiting and has reasonable fluid intake. Make sure the baby is not drinking any juice. For general principles of diarrhea management please read my article Management of Gastroenteritis.

12 days is a long time for an infant to have diarrhea, even if he is well hydrated. At this point, a stool culture should be done. In addition, since the baby was treated with antibiotics, a stool specimen should be tested for C. difficile toxin to rule out pseudomembranous colitis, a rare complication of antibiotic treatment. A urine culture to check for a urine infection should also be done since a UTI may sometimes cause persistent diarrhea in an infant.

I almost never recommend discontinuation of nursing since it is the best milk for babies and is well tolerated as long as the baby is not vomiting; however, human milk has lactose just like cow's milk, and sometimes after prolonged diarrhea an infant may have relative lactose intolerance. In that case, a trial of a hypoallergenic formula like Alimentum or Nutramigen may help. If you stop nursing even briefly, it is important to pump to maintain your milk supply for your return to nursing.

If all else fails, you should consult a pediatric gastroenterologist for further evaluation and management.

Sincerely,
Dr. Warren

Rash and Weakness

Dr. Warren: First of all, thank you for taking my question. My nephew is sick. He developed spots (like chicken pox) recently and has since had weakness in his legs. My sister took him to a pediatrician and the advice was to wait for further developments. My sister is very worried because he has been a very healthy baby and has been developing rapidly (he just figured out how to crawl!). Any idea if what is going on? More information gladly furnished upon request.

-DL

Dear DL: What was the rash? Was it chicken pox? Chicken pox can have neurological complications. Sometimes a child may appear weak after chicken pox when in reality he has lost his balance. This is a temporary complication.

You say the child just figured out how to crawl. What is the evidence that your nephew has weakness in his legs? Did he lose the ability to do something he could previously do? Based on your scant description of the events and your concerns I'd suggest seeing a pediatric neurologist for evaluation.

Sincerely,
Dr. Warren

Scoliosis Surgery

Hello Dr. Warren: I am the mother of an eight year old girl who has been diagnosed with scoliosis. Her back has a 40 degree curve already and appears to be getting worse. She is currently under the care of a physician who takes periodic x-rays to check on the progression of her scoliosis.

My question is where and how can I find an pediatric orthopaedic surgeon if (as has been suggested) Holly has to have surgery to stop the progression of her scoliosis? I live in ****, Missouri and there are no pediatric orthopaedic surgeons in my city that can do that sort of surgery. We are close (within 3 hours) to three major cities - Tulsa, Oklahoma, Kansas City, Missouri and St. Louis, Missouri.

I have been trying to find a place on the internet that will recommend a physician - but all the sites don't say much about the physicians record (i.e. how often they have performed certain surgeries, how qualified they are to perform a certain sort of surgery). Frankly, I am afraid of such a big problem as back surgery, with such long term potential effects for my child, being handled by anyone at all. But I would feel so much better if I could just figure out where to find the very best doctor in my area that specializes in pedicatric orthopaedics.

I know this question is a very difficult one.

Is there any way to find out things about doctors that would help me to determine which one would be the best in his/her field of study? I would like to know what kind of training (how specialized) the doctor has had and also if and how often they have been sued for malpractice and if they have ever had any license or certificate revoked for any reason - things like that.

Thank you for your time and attention. I, for one, truly appreciate your willingness to help people you don't even know. I read one time that a person could never get in to heaven on their own - that all of us will be carried there on the arms of those we have helped. Looks like you are going to have a pretty nice trip.

Thanks again.

-H's Mom

Dear H's Mom: Unfortunately I have been little help to people seeking experts in their area since, with few exceptions, I only know physicians on Long Island. To the best of my knowledge, there are no internet resources which rate physicians. Since no rating system is fool proof, I can imagine the legal issues involved in posting such information. There is a web site, DoctorDirectory.com, at http://www.doctordirectory.com which claims to provide a referral service to the best doctors for a fee. You can check their site to see if their methods for finding the best doctors suit your needs. As to whether or not they truly have the best doctors, I have not used their services so I cannot endorse them. You will have to decide for yourself. As far as I know, I'm not listed, but then, I never claimed to be the best.

You can do a web search using a search engine like Google searching for Orthopedic Surgeon and you will probably get a number of personal web sites in which the physicians will have posted their credentials. I can assure you that they won't post their malpractice history. In addition, I would urge you to be cautious about evaluating malpractice history if you can get the information. Just because an outcome is bad doesn't mean the surgeon isn't good. Just because the surgeon is sued doesn't mean he was negligent. Those surgeons who handle the most complicated cases are most likely to have the most surgical complications.

You can contact your state medical society or the closest medical school or children's hospital to see if they can help you find a pediatric orthopedist in your area. There are surgeons who specialize in scoliosis surgery.

Finally, you should ask the doctor who is treating her for a referral. If you are not seeing an orthopedist now, your physician should contact an orthopedist he knows for a recommendation of who to refer you to. Just as every physician has specialists he refers his patients to, every specialist has an expert to whom he refers his most complicated cases. If you just follow the path your specialist sends you down, it should eventually lead you to the expert you need.

Sincerely,
Dr. Warren

Prenatal Ultrasound Shows Brain Cysts

Dr. Warren: I just found out that my baby has cysts on the brain being 5 months old in the fetus. What does that mean exactly, and how serious of a problem this may be. I would appreciate it if you can respond back as soon as possible.

Sincerely,
-A Concerned Parent

Dear Concerned Parent: Sometimes conditions may be evident in prenatal ultrasound studies which are no longer evident after birth, so unless your doctor believes that this is a serious condition, it's too early to be alarmed. Even though the incidence of artifact on prenatal ultrasounds is low, it is possible that what looks like a brain cyst on the ultrasound really isn't one. Was your doctor able to tell you how much of the brain was effected by the cysts? i.e., how much normal brain there was? Could the doctor tell if the rest of the brain was normal? Did the doctor have a diagnosis based on his findings? These are crucial questions in order to know the answer to your question.

Sincerely,
Dr. Warren
