Nephritis

My mother tells me that I had nephritis as a child of 3. She says that I might need dialysis and a kidney transplant. What is this and what should I do? I feel fine and have not had any trouble since.

Nephritis is a term that means an inflammation of the kidneys. There are many forms of this condition and the outcome varies as to which form it is. As you had yours in childhood and you have had no trouble since it is likely to be “acute post-infectious glomerulonephritis”. In some people with this an infection, commonly Strep. throat or school sores, it triggers a response from the immunological (defence) system to fight the infection. The kidney is not infected but is attacked by the immunological system causing inflammation (the body’s response to any insult).

The good news is that if this is what you had, there is a 90% chance that your kidneys have recovered completely and there should be no problem.

If you want to be certain that you have no problem, your doctor can send some of your urine to see if there are any signs of glomerulonephritis and some blood to see if your kidneys are functioning normally.

Painful foot

My 5-year-old son often complains of a sore left foot. It looks normal and he is generally well with a good appetite. He enjoys school. What could be the cause of the painful foot?

Probably the commonest cause of sore feet is poorly fitting shoes. If this has been checked and excluded, a fracture or a foreign body may be present. So an examination by your doctor and possibly an X-ray would be warranted. He/she can also look for any other causes but these are extremely rare. I can only recall 2 cases where a sore foot (with no other joints involved) was the way a more general disease presented.

Pain around the ankles, especially with feet that roll in could be helped by a podiatrist. However if the pain is in a foot and there is no obvious abnormality would probably represent poorly fitting shoes, a fracture in the foot or foreign body. Plantar warts on the sole of the foot are painful but obvious.

Persistent diarrhoea after gastroenteritis

Our 4-year-old daughter has diarrhoea. It started with vomiting at the time when a lot of her Kindergarten friends had vomiting and diarrhoea with blood in the stools. Everyone else has settled down but our daughter still has diarrhoea and tummy pain. Our doctor has looked for a germ in her bowel but nothing was found. Have you any suggestions?

When diarrhoea is bloody, especially if there is a high fever as well, we think of gastroenteritis germs that are slightly unusual. Blood can occur in any form of “gastro” but it is commoner with the rare germs that cause “gastro”.

Because your doctor has not found a germ I would suspect one called Yersinia. Young children with Yersinia usually settle down in 2 weeks but it can persist and cause on-going diarrhoea and tummy pain. Yersinia does not show up on the standard tests that the laboratory uses to grow the “gastro” germs. To find Yersinia the laboratory needs to be told that your doctor suspects it. They will then test the stool specimen in a different way. I suggest you ask your doctor to send another stool specimen specifically to detect Yersinia.

There are treatments for Yersinia but some doubt whether they clear the germ from the gut faster than nature would anyway. I think if it were my child, I would want to be certain that Yersinia was present before considering treatment.

gastroenteritis

What is gastroenteritis and how should it be treated? One hears so many different opinions.

Gastroenteritis (often called “gastro”) occurs most commonly in the late winter to early summer, although it can occur at any time of the year. It is an infection of the gut but in a previously well child antibiotics will NOT

PRODUCE A QUICKER CURE THAN NATURE.

The major symptoms are diarrhoea and vomiting (D&V). Often the vomiting comes before the diarrhoea by a day or so. There may be some minor tummy discomfort but severe pain makes another cause for the D&V likely. However, by far the commonest cause for D&V is gastroenteritis.

The greatest danger of gastroenteritis is fluid loss leading to dehydration. The child becoming quiet and lethargic suggests that this has happened. This or refusal to drink mean medical attention should be sought urgently.

Parents by administering large amounts of clear fluids can prevent the dehydration in many cases. Food or milky drinks may make the dehydration worse and should not be given. The doctor or pharmacist may recommend and electrolyte mixture that contains easily absorbed sugar and minerals. These will rapidly travel into the body (be absorbed) with the water. This will prevent the onset of dehydration in most cases. The electrolyte mixture is dissolved in a stipulated amount of water and it is most important that these instructions be followed exactly.

Often before dehydration the child may complain that the mixture tastes too salty in which case more water can be added or clear lemonade (&-up etc) can be used instead.

Although al formula and other milky drinks should be avoided, breast-feeding should continue. Breast milk is rapidly absorbed and does not make dehydration worse. It also contains a number of agents for fighting the infection causing the gastro (see a previous answer about breast-feeding), leading to quicker recovery.

If dehydration is significant the child will be admitted to hospital and fluid given by intravenous drip or by naso-gastric tube depending on the severity of the dehydration, age of the child and other factors. A naso-gastric tube is a plastic tube passed through the nose down into the stomach.

Most of the bacteria and viruses that cause gastroenteritis are highly infectious. Hand-washing after contact a gastro sufferer is the best defence against infecting someone else including family members.

Cluster headaches in a 17 year-old

Our 17-year-old son has bursts of headaches. They are severe and come out of nowhere. The pain is around his eye, which runs as does his nose. He can have 4 a day for several weeks and they last for half an hour or longer. He becomes very agitated with them. Is this migraine?

We have an expression in Medicine “Are you a lumper or a splitter?” By this we mean some doctors will lump closely related conditions all in the same box and then say there are variations. Other doctors split conditions into finer and finer categories. The lumpers would say that your son’s condition is a form of migraine. The splitters would say this as a Cluster Headache. Both groups agree that whether migraine or cluster headaches, both are due to changes in the size of blood vessels inside the head.

Cluster headaches are commoner in males than females but occur in both sexes. Although mainly around the eye and temple, they can spread to other parts of the head. The pain is sudden and severe with no warning. It usually lasts half to 2 hours and may be accompanied by watering of 1 eye and nostril. The commonest time for them is at night. The bouts usually last a month or 2 with the patient being well in between for up to 6-12 months.

Preventer medication can be used during the bouts and pain relievers do help the pain when it occurs. There is sometimes an obvious trigger with perhaps the most frequent being alcohol; during the bad month. If such a trigger is identified it should be avoided during the bouts.

High Blood Pressure at 15 years

My 15-years-old daughter has been complaining of headaches and was found to have high blood pressure. Isn’t she too young to have high blood pressure?

High blood pressure is much less common in children and adolescents than in adults but it does occur. In younger people it is important to look for an underlying cause such as kidney disease, narrowing of important arteries and other conditions which are causing “secondary high blood pressure”. I well remember a young nurse who told me that her doctor was treating her with high blood pressure pills. I encouraged her to have someone look for an underlying cause. She was found to have a narrowing of the main artery to one of her kidneys. The narrowing was repaired at operation and she has had no problem with her blood pressure since.

Measuring blood pressure in children and adolescents can be tricky. If one uses an arm cuff that is too small for the patient’s arm, a false high value can be obtained. Also, at any age, if one is nervous then blood pressure goes up moderately.

I think your daughter should have her blood pressure checked again and if it is still high, she should see a specialist to arrange tests looking for an underlying cause.

Flat feet and falls in a toddler

My daughter, who is 2,has very flat feet. She walked at 13 months and is very active but falls over a lot. What should I do?

Toddlers often have flat feet. They are due to lax ligaments (structures that hold our joints together) and the fact that the area where the arch of the foot is located contains a lot of fat, so that little or no arch can be seen in toddlers. Walking at 13 months is normal and of no concern.

It is normal for toddlers to fall a lot- they usually have bruises on the fronts of their legs and their foreheads are often bruised. falls on flat surfaces are not a worry. However, you should protest them from falling downstairs (by a gate at the top) because serious damage can be done. Likewise, the play area outside should not have steep areas or cliffs where a toddler can fall and do themselves harm.

Fever and rash in an 8-month-old

Our 8-month-old son has been very hot for the last 4 days. I have seen his doctor who has not been able to find a cause and just prescribed Tylenol when he is irritable. He has developed a red spotty rash today but seems less feverish. Is this measles?

No, this is not measles. From your description he has had Roseola. It is also known as “erythema subitum”. Erythema means redness and subitum refers to the subsidence of the fever. Thus, as the fever stops the rash appears.

This is a viral infection that is very difficult to diagnose until the rash appears. The rash will disappear in a couple of days and your child will be happy and well.

Febrile Convulsions

My 25-month-old daughter has been in hospital for the second time with a febrile convulsion. I have been told that it is not epilepsy but they look like an epileptic convulsion that I saw on a video once. What is the difference?

The convulsion of febrile convulsion and that of the commonest form of epilepsy (generalised tonic-clonic or Grand Mal) are identical in appearance. The difference is that febrile convulsions only occur in young children (usually under 3 but sometimes up to 6 years). Commonly there is a family history of febrile convulsions. If a father, mother, sister or brother had febrile convulsions there is a 16 times greater chance that a young child will have one compared to a child with no family history. Because you and her father would not recall having had them at such a young age, it is worth checking with your parents or an older relative about the chance that you did.

Because an epileptic convulsion may be triggered by a febrile illness in a child, who has epilepsy and they look identical to febrile convulsions it is usual to wait until a second one occurs. In 60% of children with febrile convulsions there is only 1 episode but in 40% they are repeated. If a second episode of convulsing happens an electroencephalogram (E.E.G.) may be performed. This is a painless procedure in which the brain’s electrical activity is recorded while not fitting. If this is normal it is very unlikely (although not impossible) that the child has epilepsy.

A reassuring fact is that febrile convulsions are much commoner than epilepsy at your child’s age.

Eczema in a 10-week-old

My doctor has diagnosed my 10-week-old son as having eczema. We have been given some cream but could you explain eczema to me?

Eczema means a scaly rash. Most doctors mean “atopic eczema” when they just say “eczema”. There are other scaly rashes that are called eczema. Another eczema that is common in babies is seborrheic dermatitis. As both it and atopic eczema improve on corticosteroid creams telling the difference may not seem important. However, the course of the condition will be very different.

Atopic eczema is part of atopy in which some combination of the following may occur: asthma, hayfever (allergic rhinitis) or a tendency to allergies. Seborrheic dermatitis tends to disappear by 2 years, only to reappear as dandruff in adolescence. Many cases of atopic eczema also disappear by 2 and most have resolved by 6. Some remain life-long.

It is important to emphasize that your child may grow out of his eczema and never develop any of these conditions in later life, no matter which of these 2 common scaling rashes he has.

Eczema does not produce permanent scarring by itself. If it is scratched (and eczemas are very itchy) it may become secondarily infected and antibiotics needed. If this secondary infection is severe, it may cause scarring.

Babies with eczema in the diaper region (usually seborrheic dermatitis) may have repeated and very difficult to control diaper rash. This will require antiseptic baths as well as corticosteroid cream – this require medical attention and advice

Anaemia in a 2-year-old girl

What is anaemia and how do I find out if my daughter has it? My mother tells me that I looked very pale as a child and was diagnosed as having anaemia. My 2-year-old daughter looks pale but she is otherwise well.

Anaemia is a reduced number of red cells in the bloodstream. These red cells contain haemoglobin and use this to carry oxygen from the air in our lungs to all parts of the body. If we become anaemic slowly, the body compensates, for example the heart beats more strongly and more rapidly. So we may not notice that we have a problem but if the anaemia is bad enough the anaemic person looks pale.

Some people, both adults and children, are naturally pale without having anaemia. To find out if your daughter is anaemic she needs to have a blood test. This can be organised by your local doctor.

If anaemia is present it is necessary to find out why. Most of the many causes of it are readily fixed. In a 2-year-old the most likely cause would be an inadequate amount of iron in the child’s diet. The best source of iron is red meat. If a significant iron-deficiency is found, this can be fixed by giving iron medicine by mouth in a single dose per day

Glue ear in a 2 and half year old

Last week you answered a question about infection in the middle ear. My 2 and a half-year-old son has a condition called glue ear and his paediatrician has referred him to an ENT surgeon for possible operation. What is this condition, what causes it and does he really have to have the operation?

“Glue Ear” (or serous otitis media to give it its medical name) is a condition in which there is a collection of fluid in the middle ear on a persistent basis. This is due to poor drainage of the middle ear by the tube, which drains into the nose (even though the common cold is not present).

This may lead to repeated ear infections because the fluid provides a suitable place for bacteria to grow. It can also cause a hearing loss. The ENT surgeon can cut the eardrum under general anaesthesia. He/she can suck out the fluid and place a tiny drainage tube in the eardrum that will drain fluid and prevent the fluid from rea cumulating.

If there is temporary deafness speech development is inhibited but this will pick up once the deafness resolves. Glue ear usually resolves by itself and studies done comparing children who have their glue ear treated by surgery with those in whom no surgery was done have found no difference between the 2 groups after 5 years. Even the speech had picked up so that the 2 groups had similar speech and intelligence at the end of the 5 years. There is no doubt that surgery restores hearing immediately.

I hope this helps you make up your mind as to whether to have the surgery done on your son.

otitis media in an 18 month old

My 18-month-old has had 3 bouts of otitis media. I am confused as some doctors say that antibiotics are needed to clear the infection and others don’t think they are needed. Can you tell me about this condition and how it should be treated?

Otitis media or middle ear infection (sometimes called ‘ear infection” which is wrong) is a frequent problem in early childhood although it can affect any age – I had it at 17 years of age. It is usually a complication of the common cold. The middle ear has a tube which drains mucus made in the middle ear into the nose. Swelling of the lining of the nose, caused by the cold, blocks the drainage of the mucus. Bacteria like to grow in any trapped fluid in our bodies and will grow in the mucus setting up a middle ear infection (otitis media).

It is possible for this infection to develop into an abscess, which in turn may burst through the eardrum causing pain and then discharge of pus out through the outer ear. For this antibiotics are compulsory. Such rupture of the middle ear drum is very rare in well-nourished basically healthy children but is common in poorly nourished third world children where it is a common cause of a permanent hole in the drum which causes significant hearing loss.

In the last 25 years we have come to realise that a well-nourished child will get over otitis media without the need for antibiotics just as fast as those given them. It has been estimated that one has to give antibiotics to 14 children with otitis media to help 1 – the other 13 will resolve their infection just as quickly without any medication. Thus, you are likely to see less and less prescribing of antibiotics for middle ear infections in future.

Chronically constipated 2-year-old

Our 2-year-old daughter has repeated problems with constipation. We have tried a number of medicines, which do help, but as soon as we stop them she becomes constipated again with very hard bowel actions like pebbles and sometimes there is blood on them or the toilet paper. We can see that she holds back on using her bowels because of fear that it will hurt which it often does. What is your advice?

This is a miserable problem for your daughter. The blood suggests that she has a crack in her anus (technically called a fissure-in-ano). When this is torn open by the hard bowel action it hurts so that she is reluctant to do the job.

There are two steps I would suggest:

Firstly use one of the medications that has worked again but for 3 months! Ask her to go and try to use her bowels after the 3 major meals.

If she fails to pass anything for 24 hours then increase the dose – I usually recommend doubling the dose. If that fails then she needs a suppository or enema, which your pharmacist can give you.

Secondly I recommend some anaesthetic ointment put on at least twice a day – after her bath and then about 12 hours later. This is applied to the anus and does not have to be inserted, just put it on the surface. This is to stop the passage of the bowel action from being painful. Once the process is painless you can stop the ointment.

I strongly emphasise the importance of continuing the use of medicine for 3 months even though she may seem cured much earlier. Towards the end of the 3 months you can try reducing the dose say halving it for a week. If there is any failure to use the bowels for 24 hours, double the dose again.

This is a difficult and complex matter and I would be only too happy to answer supplementary questions. Best of luck.

Repeated Cold Sores

I need your advice on cold sores. I get them but only once or twice a year and my wife does not have them at all. My son who is in his final year of High School and is studying very hard, is having multiple attacks. Do you think they may be stress related? Is there any protection we can practice? Given that we never kiss him on the lips, where are they coming from (he does not have a girlfriend)?

Cold sores are an herpes infection. We all have an initial herpes infection in our first few years of life. Then it causes mouth ulcers. After the infection is over the herpes virus remains in the nerves that supply our lips. Most of the time we suffer no harm from this carrier state. Unfortunately, for about 40% of the population, when they are stressed, the virus becomes active and the ulcers appear on and near the lips again.

The most common cause of that stress is the common cold, hence the name cold sores. However, the stress may be emotional and it seems likely that is the case for your son.

There is an anti-viral cream that is effective in herpes but as each attack is self-limiting, it should only be used in the most severe cases for fear of the virus becoming resistant to it. Babies or the very elderly can get the herpes virus in their blood stream when it is frequently fatal without this anti-viral agent. In my opinion, we should reserve this agent for these cases or particularly severe skin herpes.

Anyone with active cold sores should not go near a newborn baby (under 1 month of age). If avoidance is impossible, a mask can be worn. However, the mask must be changed and hands washed every 20 minutes if the contact with the baby is to be prolonged. I must say it is rare in my experience for the mother with cold sores to give the virus to their baby.

I am one of the 60%. Who do not have repeated cold sores, but I feel very sorry for those who do.

Childhood Illness

Why does my 3-year-old daughter have so many coughs and colds?

Coughs and colds are the commonest illnesses that children suffer. As coughs can be due to serious illnesses such as pneumonia or asthma, the parental anxiety a child’s cough can cause is quite understandable. Pre-school children have an average of about 9 upper respiratory infections (colds) per year and more if spending a lot of time with other children (being in child care for example).

The vast majority of colds are viral and do not respond to antibiotics. A very small number of children will develop a secondary bacterial infection such as bacterial tonsillitis which will require antibiotics. This secondary bacterial infection is so infrequent that the use of antibiotics to prevent it is not justified, especially when one considers the side-effects that the antibiotics may cause. 40% of patients given erythromycin develop nausea, abdominal pain vomiting or some combination. Two thirds of children when given amoxicillin under the age of 2 years will develop loose bowel actions.

So what is to be done? Medical Science has not found a way of shortening the common cold. It is important to keep up the fluids, as fever causes the child to lose water through sweating. If the child is uncomfortable they may have paracetamol (acetophenetidin or phenacetin). Regular paracetamol is not necessary; it will lower fever but fever is one of the defence mechanisms that help the body fight infection.

Aspirin is a definite no-no in young children.

If the child will not drink or looks obviously sick (listless, drowsy, struggling to breathe) then see a doctor. The person who discovers a cure for colds will become very rich and probably win the Nobel Prize

Childhood Illness

Should I have my baby boy immunized against chickenpox? I have heard that sometimes it gives them chickenpox.

The short answer is “Yes you should have him immunized for chickenpox”. Of course it means an extra needle and the very low risk of side-effects that all immunizations have.

Chickenpox (varicella) is one of the most infectious of the infectious diseases with about 90% of household contacts, who have not had chickenpox, catching it if one person in the house develops it. While more than half of cases occur in children under 10-years-of-age, 25% happen in people over 15. Ask anyone who contracted chickenpox when 15 or older and they will tell you that it is a miserable disease with intense itching.

Also 1 in 100 people (adults or children) will develop a secondary pneumonia requiring antibiotics and often hospitalization. Some children develop an involvement of the brain called encephalitis. Overall the complication rate of chickenpox is 5 to 10% and one in 400 children being hospitalized.

What are the risks to the chickenpox immunization? About 10% will develop a fever and half it will be quite high (greater than 38.degrees Celsius or 101.3 degrees Fahrenheit). One in5 children will develop slight swelling, pain or tenderness around the injection site. This clears up without any need for treatment. About a fortnight after the immunization approximately 4% will develop some chickenpox lesions around the injection site and about the same number will develop them somewhere else on the body. However, the number of these lesions is 5 or less. Compare this with more than 300 chickenpox lesions in naturally caught chickenpox and each of those 300 itches!

Both my older brother and sister had escaped chickenpox through primary school. I developed it when I was 9 years-old. Of course they both caught it from me during their summer break. My illness was relatively mild but my brother and sister itched horribly and they were not impressed with their kid brother! My last 2 children also caught it in adolescence, the older one did not sleep for 2 successive nights because of itch and this was despite excellent nursing care from his mother and generous medication from his father.

Eczema atopic & seborrheic dermatitis

My doctor says my 10-week-old son has eczema and prescribed some cream. What is eczema and will he have it all his life?

Eczema means a scaly rash. Most doctors mean “atopic eczema” when they say “eczema”. There are other scaly rashes that are called eczema. A similar rash to atopic eczema that affects babies is seborrheic dermatitis. As both these types of eczema (atopic eczema and seborrheic dermatitis) improve on corticosteroid creams, knowing which form of eczema it is may not seem important. However, the course of these 2 conditions will be very different. Atopic eczema is part of atopy and babies who have it may develop asthma, hayfever and an undue tendency to allergies. Seborrheic dermatitis tends to disappear by 2 years, only to reappear in adolescence as dandruff.

It is important to emphasize that your child may grow out of his eczema and never have any of these other conditions in later life, no matter which of these 2 scaling rashes he has.

Eczema does not produce permanent scarring by itself. It is itchy and if scratched, it may become infected and require antibiotics. If this secondary infection is severe it may cause scarring. Babies with eczema in the nappy region (usually due to seborrheic dermatitis) may have recurrent and very difficult to control nappy rash. This will require antiseptic baths as well as the corticosteroid creams- this needs medical attention and advice.

Gastro-oesophageal reflux in babies

Our 2-month-old baby cries a lot and the doctor has diagnosed reflux and given an antacid. The baby vomits a lot and seems unhappy but is growing satisfactorily. Can you explain reflux to me?

The full name for this condition is Gastro-oesophageal-reflux. Other kinds of reflux can occur elsewhere in the body. I don’t blame your doctor for using the shortened name and I will too for this answer. In this condition stomach contents pass back up (reflux) from the stomach into the gullet (oesophagus).

Such reflux is common in babies as they take a large quantity of fluid for their size. If an adult was to take the same amount of fluid per kilogram body weight, he/she would drink 7 + litres per day.

This huge intake of fluid puts a lot of pressure on the valve-like mechanism that normally stops fluid from passing from the stomach and back into the gullet. Forty percent of babies vomit after feeds because of this reflux and in most cases it does not cause a problem. There are 3 complications of reflux that do cause problems:

The acid made in the stomach may cause irritation to the lower part of the gullet. This is painful and makes the baby irritable. It seems this is what your doctor suspects.

The refluxed stomach contents may come up to the point where the gullet and the windpipe branch of the lower throat. This causes a potential for those contents to be inhaled. The first part of the windpipe has a trapdoor (epiglottis) which closes when we are eating, vomiting or refluxing. If this fails then we can inhale the refluxed material causing chest disease. This is quite rare in normal babies – only 1 in 500 refluxing infants have this complication.

The baby may bring back so much of his/her milk, that not enough is consumed. This would make the baby hungry and demanding. After some time growth would be noted to be inadequate. This complication is extremely rare- in 40 years of paediatric practice, I don’t think I have ever seen it.

Reflux disappears spontaneously as the baby drinks less per kilogram and adopts the upright position. The average age of it stopping is 10 months but there is a wide range of ages at which it stops. Most adults have occasional episode of reflux when we are aware of fluid coming back up into our throats – we just swallow it and do not worry.

Our 6-year-old son has lots of bruises on his arms and legs. He is still active but I am terrified that he has leukaemia. What should I do?

I am not surprised that an active 6-year-old boy is collecting many bruises. Because you are terrified, I suggest you see your local doctor who will do a blood test to exclude it and other possible causes for excessive bruising.

Bruising by itself is not a common way for leukaemia to show up. Other signs of leukaemia are anaemia with paleness and being less active, an unusual number of infections or unusual types of infections such as mouth ulcers, bone pain or tenderness and sometimes lumps may be found in the neck – although there are many other causes for these.

If the bruising is excessive and he is otherwise well, he may have Idiopathic Thrombocytopenic Purpura (or ITP for short). This will show up in the blood test and is treatable.

Even in the unlikely case that it is leukaemia nowadays the most common type can be cured in 80-90% of cases but I doubt that your son has leukaemia

When a child should attend Emergency Room

When is a child sick enough to go to the Emergency Room?

A sick child can be an enormous concern to a parent. The normal young child can have up to 12 colds in a year so what are the signs that should prompt you to go through the unpleasantness of attending an emergency room? In my opinion the main ones are:

Drowsiness

Refusing to drink at all

Vomiting everything

Excessive irritability

Marked pallor

Struggling for breath

I could make a list that would go on and on for instance convulsions or coma but these are so obvious that I have not included them or other signs that would prompt any parent to seek urgent attention.

The child who is active &/or drinking well is unlikely to have a serious illness, whereas the combination of drowsiness, severe irritability when disturbed, absolute refusal to drink (not just less drinking) and vomiting is a particularly worrying one.

The experienced parent is able to recognize the pattern of minor illnesses and give Tylenol for discomfort, keep up the fluids and rest for their child. Unfortunately, when we first have children none of us are experienced and will often consult the doctor with minor ailments but it is the doctor’s job to look after such children as much as the sicker ones.

If a doctor is patronizing or otherwise makes you seem silly he/she probably does not

have children or is stressed by their job or some other factor. If you are worried it is better to put up with such an attitude than to be sorry that you did not see the doctor.

Baby with difficulty in breathing (bronchiolitis)

My 4-month-old niece has just been admitted to hospital with bronchiolitis. She looks very distressed and is struggling to breathe. What is bronchiolitis and can my baby catch it – we visited when my niece had a cold 4 days ago?

Bronchiolitis in babies is a viral infection of the smallest airways in the chest (called bronchioles). It causes at least 1% of children under 2 years of age to be admitted to hospital and is one of the major reasons for the children’s wards of hospitals to be very busy over late autumn and winter. It is most commonly due to an infection by the Respiratory Syncitial Virus (RSV). This virus is highly infectious and can survive outside the human body for eight hours. So, if you touch a surface that has been sneezed or coughed upon you will pick up the virus on your hands. If you then rub your eye or nose you will infect yourself. Except in babies or asthmatics this will only mean an adult or older child will develop a cold or “chest cold” but the carrier of the RSV is a walking time bomb for any baby you handle. This is why hand washing is an obsession for nurses, doctors and other staff who handle children. It also means that it is likely that your baby probably has become infected with RSV but remember every child under 2-years becomes infected with RSV. Only 1-2% have to be admitted with bronchiolitis the other 98-99% just develop a bad cold.

The infection of the bronchioles causes swelling of the lining of these small tubes. This makes it difficult to move air in and out and the baby has to breathe harder and their oxygen levels may fall. As drinking from the breast or bottle is the hardest work a young baby has to do, they may become too tired to take in their daily requirement and many hospitalised bronchiolitics become dehydrated. Fortunately the body’s defence mechanisms against infection mean that on about the 4th or 5th day of hospitalisation most babies will start to become better but they may need intense medical/nursing care before this happens.

The hospital management of bronchiolitis is to give oxygen if the oxygen levels in the blood are low and extra fluid by a tube through the nose into the stomach or by a drip into a vein if dehydration is likely or has occurred. One patiently waits for the baby’s defence systems to fight off the infection. Death from bronchiolitis is extremely rare unless a pre-existing heart or lung condition compromises the baby.

Please remember to wash your hands before handling a baby so that you are not responsible for transmitting RSV infection.

Bedwetting in a 6-year-old

How can I stop my son’s bedwetting? He is 6-years-old and wets about 6 nights in 7. His older brother was dry from about 4 years of age but I wet until I was about 10 years and was very embarrassed by it. I want to save my son that embarrassment.

We all wet the bed when we were babies. We first learned to not pass urine (even though our bladders were full) while awake when it was socially inconvenient to do so. Later we learned how to hold on while asleep. The time when a child learns these skills varies from one child to another just as some children will learn to ride a bicycle later than others.

The usual age at which a child is dry both day and night is 4 years but 25% of children are still wetting the bed at 5. Each year about 10% of these children will learn the skill and stop wetting the bed. Late control often runs in families and does not represent disease. There is no association between bed-wetting and general intelligence.

A somewhat more serious situation is the child who has been completely dry for some time then starts to wet again. Such a child should see a doctor to check for illness – the most common being urinary tract infection- or emotional disturbance. The emotional disturbance may appear trivial to an adult e.g. changing school.

As bedwetting is difficulty in acquiring a skill threats, punishments and bribes are doomed to fail. A not-promised reward for a dry night is fine. The parent’s attitude should be matter-of-fact: “Oh, you have wet the bed, just put your sheets in the washing machine.”

When the child is motivated (parental motivation does not count) to stop, the best method is the bedwetting alarm that makes a buzzer sound as soon as the child starts to wet. However, the child must “psyche” up him/herself, so when the buzzer goes they wake up. Hence, the child’s motivation to stop is essential.

There are some drugs that bring temporary control for a sleepover or school camp but these do not cause a permanent cure as the alarm can

Repeated vomiting in a 7-year-old

Our 7-year-old son has repeated episodes of frequent and severe vomiting. He has just been seen by a paediatrician who diagnosed cyclical vomiting. Our boy is often hospitalized, as he needs a drip to treat dehydration. Can you tell us more about cyclical vomiting?

Cyclic or cyclical vomiting is a most unpleasant condition, the cause of which is unknown. To accept this diagnosis, your child should be completely well between episodes. Cases due to psychological upset have been described but are very much in the minority. Rarely the use of preventative anti-migraine therapy has proved beneficial suggesting that the episodes are due to abdominal migraine – again these are very much in the minority.

So what can be done for the majority of cyclic vomiters for whom no underlying cause is found? Dehydration is the life-threat in these patients and if it occurs an intravenous drip is necessary. To try and stop this from happening a very powerful anti-vomiting agent ondansteron is given. It is a very expensive drug but is worth it if it can reduce the vomiting so that a drip &/or hospital admission is avoided. Sometimes corticosteroids are also given. Despite these measures the patient still has to be hospitalized in many instances in my experience.Fortunately most children (but not all) “grow out” of the condition, so that it ceases after some years without any reason for the cessation. This condition is very frustrating for the patient, the parents and the conscientious medical practitioner who spends much time considering other possible causes, trying anti-migraine and other treatments while feeling very sorry for the families

Inhaled corticosteroids for asthma

Our 2and a half-year-old son has repeated asthma attacks that usually respond to nebulizers at home but he has been hospitalized twice this year. His doctor and the hospital want to put him on a steroid preventer twice a day. I am concerned that the steroids will stunt his growth and give him other problems. What do you think?

Your concern is very common. So much so that a term “Steroid Phobia” has been coined for it. The term phobia is a bit harsh because corticosteroids can cause serious and minor side-effects if given in big doses. However, the dose of steroid given by puffers is so small that it will not cause these side-effects. The great beauty of the inhaled steroids is that they are delivered to where they are wanted – into the airways. They do not go to the rest of the body as they would if swallowed or injected. Any inhaled steroid that is absorbed from the lungs or accidentally swallowed, is 90% destroyed by the liver in 1 second. This means it does not get to other parts of the body and cannot cause side-effects.

Thus, if the correct dose is given, an effect on growth or side-effects is very unlikely. Occasional patients (I have only seen 1 in my career) are unduly sensitive and this will first show up as excessive weight gain. In this case some other preventer is tried. The other group of preventers are also inhaled and stop the release of chemicals in the airways that cause asthma. These are very safe but unfortunately only work in 75-90% of patients. You will need a 4-week trial of giving them twice a day before knowing if they will work or not. Yet another class of drugs called leukotriene inhibitors are relatively new and again seem not to work in everyone.

You specifically mentioned concern about stunting of growth. This has been well looked at by a 25-year trial in which 3 groups of children were followed. These were normal children, asthmatic children not given inhaled corticosteroids and a 3rd group with asthma who were given inhaled corticosteroids. The normal group grew best but importantly the asthmatics on steroids grew better than the asthmatics not given inhaled steroids. Also, the children with asthma given steroids were only a little bit shorter (about 1 inch or 2.5 centimetres) than the normal children.

As he has been hospitalized twice this year your son should be on a preventer.

Toddlers Diarrhoea

My 2-year-old boy has loose bowel actions and is filling his diaper very frequently. He seems well and our doctor says he is growing ok. A number of tests have been done and none show a problem. What do you think is causing this?

Your son’s problem is quite common. Sometimes it is due to a persistent infection in the bowel and I imagine your doctor has sent off bowel actions to exclude this. One bowel infection that can be difficult to pick up in this way is due to a bug called Giardia and often treatment for Giardia is given even if it is not detected.
A persistent infection elsewhere in the body can also cause diarrhoea and one that is often hard to find just by looking at the child is a urinary tract infection. If not already done, it would be worth sending a urine sample to the laboratory to exclude infection.
As he is growing well it is unlikely that his gut is having difficulty in absorbing his food which is another cause of large quantities of bowel action. For the same reason and his young age he is unlikely to have inflammatory bowel disease such as Crohn’s Disease.
Sometimes an allergy to cow’s milk can cause diarrhoea. You might like to try him on a milk free diet (that is no milk, ice-cream, cheese, dairy products or manufactured products that contain milk such as bread and biscuits) for 3 weeks. Then put him back on his normal diet. If there is a dramatic improvement in the milk-free period followed by a resumption of diarrhoea when milk is taken then he probably has milk allergy. You should then consult a dietician for advice on a long-term milk free diet with calcium supplements. He will need to be on the diet for months before another milk challenge.
The commonest cause of persistent diarrhoea in an otherwise well toddler is called “Toddler’s Diarrhoea”. We do not know the cause of this condition and there is no treatment but the good thing is that it gets better by itself. Because there is no test for the condition, we like to exclude the known causes of diarrhoea that I have described before diagnosing Toddler’s Diarrhoea. The use of agents to slow down the bowel can be dangerous in that there is only a very narrow gap between the effective dose and the dose that is toxic in children. This makes it very easy to “poison” the child accidentally – a sorry outcome for a nuisance condition rather than a true health threat

Caesarian Sections

Why are Caesarian Sections so frequent these days and do they harm the baby?

Caesarian Sections are done more frequently now compared to 40-50 years ago. This is happening all around the world and the major reason is to protect the baby. Natural (i.e. vaginal) childbirth is heavily promoted these days and in general the mother recovers more quickly than a woman who has had a Caesarian. However, while it is the right of any patient to refuse treatment for themselves, the rights of the baby need to be considered in the decision as to Caesarian Section.

Caesarian Sections can be life saving for the baby and sometimes for the mother. At other times they may be necessary to prevent permanent brain or other damage to the baby (and/or the mother). An example of this is the fact that caesarean Section for babies who would otherwise been born in the breech position (that is bottom first) has markedly reduced the risk of damage to the nerves of the baby’s arm and other problems.

Having a discussion as to the need for a Caesar when you are in labour and the obstetrician is worried for you and/or your baby is definitely not optimal. You should discuss this with your doctor and/or midwife during pregnancy, well before delivery.

Babies born by Caesarian Section are more likely to have a short period of breathing difficulty than are vaginally born babies. This Transient Tachypnoea of the Newborn is only for a few hours and much less serious than the condition being avoided – usually some form of brain damage for the baby.

One of my children was born by Caesarian Section because he stopped kicking. He turned out to have a severe ankle deformity. He has done very well, sailing through his University course and now holding a prestigious position in his profession. Ironically he was the best kick at football of all my children but he did spend the first 18 months of his life in night plasters to correct the deformity

Attention Deficit Hypertactivity Disorder

Our doctor has diagnosed our 6-year-old son as having Attention Deficit Hyperactivity Disorder (ADHD) and has prescribed a stimulant (Ritalin). What is ADHD and what causes it?

Attention Deficit Hyperactivity Disorder (ADHD) is a relatively common disorder which affects more boys than girls although girls certainly can have it. It causes the child to have difficulty in concentrating, be overactive and disruptive.

It is easily confused with behavioural problems due to stress from the child being upset by events at school (such as being bullied) or at home (for example warring parents or parental separation).

It is really known what causes ADHD but there is some evidence that the frontal lobes of the brain (which are behind the forehead) are slow to gain their function. The frontal lobes generate intelligence and help regulate our emotions. In a bid to stimulate the function of the frontal lobes doctors try stimulants – which seems strange in a child who is already overactive. However, the giving of these stimulants can be spectacularly successful.

Whatever the cause of ADHD it should be managed because it will interfere with learning at school and make it difficult for the child to make friends. This in turn will lead to the development of Oppositional-Defiant behaviour in late childhood or early adolescence.

Psychological counselling can also be effective in ADHD but waiting lists to see a Child Psychologist are often long. Thus, a child’s doctor may decide on a trial of stimulant medication.

One of the reasons ADHD appears to be a modern plague is that we feel the need to protect our children so much. I think that if I was a child now, I might wear that label. In my case my behaviour was related to my parents unhappy marriage. I was a child when it was easier for such children with such behaviour. From a young age I was able to leave home after breakfast to visit friends with whom I spent much time playing physical games with considerable enthusiasm but limited talent. I returned home for meals or going to bed only. So my behaviour and that of others like me caused little concern for our parents. Yes it did affect my schooling and to this day I find it difficult to stay on task for more than half an hour and one hour is tops. However, I found ways to cope and ADHD usually improves in adolescence if the Oppositional-Defiant problems have not occurred.

There is also Attention Deficit Disorder (ADD) which is like ADHD but without the hyperactivity. The inability to concentrate interferes with doing schoolwork. This may not become evident until primary school; its management is much the same as that of ADHD.

Both ADHD and ADD overlap with Auditory Processing difficulties. In Auditory Processing difficulties the child can hear normally but has a lot of difficulty to in processing the messages from the ear to the brain – it is similar to listening to a foreign language. If given complex instructions such as “Go outside, rake the leaves and put them in the rubbish bin”, the child will go outside but no be able to remember what to do once there. This condition is tested for by hearing experts using specialised techniques and information given to school teachers and parents about how to help the child.

Breastfeeding

I have noticed a lot of argument about the advantages of breastfeeding what are your views, Dr. Robinson?

Breastfeeding is best for babies until 4 to 6 months of age. This does not mean that a baby who is bottle-fed will suffer disadvantage for the rest of their life. A bottle-fed baby will take more work but a perfectly healthy baby can be obtained by bottle-feeding.

The 4 main advantages of breastfeeding are:

Nutritional

Infection Prevention

Allergy prevention

Emotional.

NUTRITIONAL

Breast milk contains substances that are not in formulas. Gradually these are being measured and many are being put into formulas. It is not enough just to put the same amount of them into formula as is in breast milk. A good example of this is iron, which is needed to avoid anaemia and has other beneficial qualities. It was discovered that the baby’s gut would take up iron from breast milk at a greater rate than it will from any formula. Thus more iron has to be put into formula than is naturally in breast milk.

Poly-unsaturated fatty acids (PUFAs) are another example. PUFAs are essential because humans cannot manufacture them – they have to be eaten. Breast milk contains them in significant quantities while, until recently, formulas did not.As these PUFAs are found in brain as well as other tissues, and the brain grows rapidly in the first year of life, trials of supplementing baby formulas with PUFAs have been undertaken. Once again it is not simply a matter of putting in the same amount as is found in breast milk. The ratio of the PUFAs to other fatty acids that are found in formula is critical.

Science around the world is trying to make formulas as similar as possible to breast milk. This work is slow and clinical trials need to be conducted with each change. The cost of this work is reflected in the cost of baby formulas which makes them a much more expensive option than breastfeeding.

INFECTION PREVENTION

Breastfeeding will make a baby less likely to pick up infections than a bottle-fed baby. The reason for this is that breast milk contains a number of substances that fight germs (bacteria and viruses).

One class of these germ-fighters are live cells from the mother. There are several different types of cells. Perhaps the most important are called macrophages. Macrophages attack any germs that enter the baby’s gut helping to prevent infection such as gastroenteritis (“gastro”). The cells will be particularly effective if mother has recently had an infection that she has passed on to her breastfeeding baby. This is because they instantly recognise that it is the same germ and know how to fight it.

Another class of germ-fighters are called immunoglobulins. If we have an infection such as measles we generally never get it again. One of the reasons for this immunity is that the cells in our body that make immunoglobulins that circulate in our blood and help to destroy the measles virus. We keep the ability to make this immunoglobulin against measles for the rest of our lives. Immunoglobulins are present in mother’s breast milk and help protect the baby from infections to which she has been exposed.

There are other protective agents in breast milk. Do all these substances really help in practice? Yes – it has been shown that baby’s who are breastfed are less likely to develop gastroenteritis than bottle-fed infants. Also if a breast fed infant does catch ‘gastro’, they will recover more quickly if breast-feeding is continued.

ALLERGY PREVENTION

Exclusive breast-feeding might help prevent the development of allergic diseases such as cow’s mill allergy, atopic eczema and asthma. The reason for this potential protection is that until 4 months the baby’s gut allows whole proteins (taken in any form of food) through into the blood stream where they can cause allergic reactions.

Scientific studies on whether there is an actual benefit from exclusive breast-feeding in the first 4 to 6 months are contradictory with some showing that it does help prevent the development of eczema and/or asthma and other studies saying it does not. Part of the reason for this is that exclusive breast-feeding is rare – a recent British study found that only 1% exclusively breastfed for 6 months (The target they set). Breast-feeding alone does not supply sufficient nutrition after 6 months of age. The infant gut has matured enough to block the uptake of whole proteins by 4 months. Hence it is recommended that solids be started between 4 and 6 months.

EMOTIONAL

Another advantage of breast-feeding is the promotion of emotional attachment between mother and child.

All mammals are breastfeeders of their young and all develop a unique bond between mother and baby soon after birth. This bond is called emotional attachment.There are many accounts of how determined mother mammals are to protect their young. Human mothers are the same in most instances.

A number of studies in non-human mammals have shown that breast-feeding promotes the formation of this powerful bonding process. Are there consequences if this unique emotional attachment does not occur? Harlow showed that the answer in monkeys is “Yes”. He took the babies of monkeys away at birth and bottle-fed them. When they were returned the monkey mothers showed few “mothering instincts” and were often violent towards their babies. Of course in the wild, mammalian babies that are not breastfed die from starvation and dehydration.

In humans, where the baby is separated from mother and not breast fed (e.g. due to prematurity) the early studies suggested that emotional attachment was slower and more difficult to achieve.

This led to considerable concern among those in child health and welfare. But we came to realise that the emotional attachment did eventually occur in nearly all cases. Also the separation was part of the problem, not just the absence of breast-feeding. Most neonatal units now allow unlimited parental visiting of premature babies or any other baby that has to be there. It is hoped that this will foster emotional attachment.

Thus the conclusion is the same as it is for nutrition and infection prevention: emotional attachment is easier to achieve if breast-feeding is undertaken but it can be achieved along with adequate nutrition and infection prevention in babies that are bottle fed. It is just quicker and easier in breastfed babies.

Childhood Illnesses

Childhood Illnesses

My 4-year-old gets his colours confused. Could he be colour blind?

It is unlikely that your son’s difficulty in correctly naming colours is because he is colour blind. It is not unusual for a 4-year-old to have this problem.

Sophisticated testing has shown that the ability to distinguish colours develops quite early. The problem for the toddler is being able to attach the right name to the colour. A 4-year-old is 3 times more likely to make this error than a primary school child is.

Development of colour naming shows wide variation between individual children and generally occurs earlier girls than in boys. My wife still corrects me on the names of colours I use!

Colour naming problems are much more likely to be the reason than colour blindness in your son and this will become better with time.

Colour blindness can be tested at this age. Not all doctor’s consulting rooms have the booklet that is needed to do the testing. So, it would be a good idea to check if your doctor has the equipment to test for colour blindness before making an appointment.

Remember that the problem is more likely to be difficulty in naming the colours rather than in seeing them and that the naming process will come with time.

Children learn what they are taught. I used to think that my older children were all very smart because they knew their colours early. Their mother pointed out that when they said a word incorrectly (EG “ird” instead of “bird”) I would reply “Yes there is a brown bird”. I did this so they would hear the word correctly but not in the way that was a put-down. An unintended result of this was that they learnt their colours early.

Infectious Mononucleosis

Could you tell me more about Infectious Mononucleosis (“Mono”)? My 9 year-old daughter contracted Mono last year. She was sick and tired for a good 6 weeks and finally seemed to return to normal about 3 months after diagnosis. Since then she has been sick a lot! She is constantly getting viruses and then secondary infections from them. She also seems to gets rundown more easily than previously. Before the Mono she hardly ever got sick. She is generally a very healthy child with no other medical problems. Some doctors say that once the mono has gone, it is gone. But I have heard that once you have Mono, you always have Mono and relapses are likely, especially when someone does not get enough rest. Could you please tell me your opinion? I am curious if the Mono is playing the part in her getting more sick more often, and staying sick longer.

In the vast majority of cases once the virus that causes Mono has been eliminated, it does not come back. A period of fatigue after Mono is well known and usually is noticed more often in older patients – adolescent and adults. At age 9 some months of fatigue would be less common but not unknown.

It is well recognized that a small sub-group of children and adults have a very prolonged period of fatigue, fevers and predisposition to sore throats. This sounds a bit like your daughter. I don’t think that extra rest is necessary. If she feels fatigued let her rest, if she wants to exercise let her even if she feels very fatigued afterwards. The reason for some boys having this persistent problem is an impaired ability to fight infections but as your 9 year-old is s girl and previously well that is very unlikely. Medical science does not find a cause in most cases with the prolonged illness.

It would be worth having a blood test (Full Blood Examination) done to reassure everyone that the cells that fight infection are there in the right numbers and are healthy. Otherwise I would give her 12 months to recover. If she does not then more extensive evaluation by a paediatrician would be warranted.

Adolescent moods


Adolescent Moods

While adolescence is the time when we are physically most healthy, it is the most difficult emotionally. The adolescent has a number of developmental tasks; becoming used to a markedly changed body, developing their own identity, learning to be able to be intimate, developing a sexual identity and preparing to become economically independent. Recently there has been much interest in a study which showed that a hormone that has a calming effect in young children and adults has the opposite effect in adolescence. This was shown in adolescent mice – it will be some time before it is demonstrated in humans and even longer before anything can be done about it. However, it may explain why adolescents fly off the handle so easily.

Also, sometimes your teenager is in “child: mode" and sometimes in “young adult” mode. It is necessary for adults to work this out and respond appropriately depending on whether it is the “child” or “adult” talking.

Some adolescents have difficulties in completing all the tasks listed above. This may lead to serious consequences (suicide, drug taking, unacceptable risk taking such as driving cars fast) but it is important to realize that most will successfully complete these tasks at their own rate. During this time of uncertainty they may adopt the behaviour of a peer or adult model which can be quite distressing to other family members and friends.

A classic study by Parcel and co-workers in 1977(1) showed that the majority of adolescents wanted their doctors to supply information about drugs, sex, sexually transmitted diseases, birth control and getting along with parents. 1 in5 also wanted help with one (or more) of the following – acne, depression, obesity and sexuality. More recent studies have shown similar results.

If an adolescent is having troubles, a very useful idea is to send them to a service for adolescents only – no parents allowed. These can be found in the telephone book. If you wish to accompany your adolescent, your local doctor is probably the first port of call. Parental presence may stop the adolescent from expressing their true concerns. I might have talked about acne with my parents present, but any of the other topics – NO WAY!

Food allergy

Three years ago our then 5-year-old daughter was hospitalised with respiratory problems. She was put on oxygen and steroids. Asthma was mentioned but I didn’t want to put her on albuterol and steroids for the rest of her life so our family changed our diet. For 3 years, she has not eaten dairy, gluten or many chemicals e.g. nitrites.

Last weekend at a relative’s house, she ate a taco with just a little bit of dairy in the seasonings for the meat. Next day her eyes were watery, red and swollen. In the past 3 years she has had watery eyes at times (if she ingested some food dyes for instance), but has not had any breathing problems or vomited. 2 days after the taco she vomited and did not try to eat until later that afternoon. That evening she had ear pain for the first time since pre-school. 6 days after the taco she had pink eye.

It would seem that your daughter did have a food reaction although from the timing, pink eye may be a coincidence. The question is: to what did she react? The taco shell probably contained preservatives. Milk allergy is rare (but not unknown) in 8 year olds. As her reaction, although unpleasant, was not life threatening, I would be inclined to expose her to milk and note the response.

To do this, put a few drops of milk on her tongue and see what happens. If there is no reaction in 24 hours try an ounce of milk as a drink. If there is still no reaction, in the next 24 hours, give her 2 ounces of milk and gradually build up in that way.

The next thing I would challenge her with is gluten, as this not usually a trigger for asthma. Again start with a small quantity and build up. If she can tolerate both it is likely that food additives are the allergy-producing culprits.

By the way asthma is not for life. 80-90% of children grow out of it. For children who have asthma early in life (as did your daughter) 50% have grown out of it by 6 years of life.

Best of luck and I would be interested to hear what happens.

Vomiting infant

I have an 8 month-old son who projectile vomits at least 3-4 times a day. I have had him to his Doctor many times now and he just says it is teething and this is normal behaviour.
My son is underweight and I worry about this as well as him dehydrating. I have never seen a teething baby projectile vomit and certainly not multiple times a day, spitting up maybe, but not to this extreme.
He has seen other Doctors in the same office and their opinion is that he has a virus. This has been going on now for 6 months.
What do you think?

I can understand your concerns. If it is projectile vomiting, it suggests he has a high but only partial gut obstruction which is at the bottom of the stomach or in his intestine very soon after. Projectile vomiting is where the vomit comes out like water from a fully turned on hose. It clears the baby’s bib and usually mother’s lap. Copious (and even forceful) vomiting that is not truly projectile suggests gastro-oesophageal reflux (a complex term that I will just call reflux from now on).

Reflux is due to a failure of the valve-like mechanism at the bottom end of the gullet where it enters the stomach. We all suffer reflux from time to time when we can feel fluid coming back up our gullets. Adults just swallow it down again, but babies let it flow out.

I agree this problem is not due to teething. All you get with teething is teeth, misery and excess salivation.

As this has been going on for 6 months, your son should be investigated. The first test should be a barium meal which will show any high gut obstruction and reflux if they are present.

Any high part obstruction will require surgery. Reflux will resolve by itself over the next few months. As he is underweight, a high calorie formula while you are waiting might be warranted. A dietician can help you with this.

Tics

My 4-year-old grandson has just developed a tic. He blinks his eyes a lot. His mother, my daughter-in-law, also has this same tic, so I am wondering if this is genetic? I’d like to learn more about tics in general and what if anything can be done about them. While we have noticed this tic, we have not commented on it to him as we don’t want to call attention to it as assume it is not under his control. Is the right approach?

I read recently that this could be caused by a magnesium deficiency and wonder if you agree with this statement?

Transient tics involving the facial muscles and eye blinking occur in one quarter of children. You have done absolutely the right thing in not drawing his attention to them. Stress usually makes them worse and as he cannot control them, commenting on them will only make them worse too. In fact constantly mentioning them can make them permanent – did this happen to his mother? They usually only last for a few months.

No treatment is effective or needed. They are much commoner in boys than girls.

Tics do occur in some illnesses but if he is otherwise well and does not exhibit any other strange behaviours, looking for these is not warranted.

The fact that his mother has tics also does not necessarily mean that the tics are genetic. Often symptoms that do not appear to have a cause run in families e.g. if mum has a headache when stressed often her children will have headaches with stress.

As regards magnesium deficiency, this can cause epileptic fits and other muscle jerks. However, magnesium deficiency is very rare – I have only seen it in 2 children who had very serious underlying diseases

Strep. throats

6 months ago my son had 90% of his tonsils removed along with the adenoids. He also had a nosebleed fixed. When we came home I noticed his nostril was closed off, well it did not get any better. It is like it was welded together. The Dr. said the scar tissue attached itself to the other side of the nostril. But I think it is something the Dr. did on the day of the surgery. Because it was like that on the same day. Also he has had Strep 4 time since then. Is there anything that I can do to prevent him from having strep so often?

When any part of the body is operated on, it swells. Swelling is a part of inflammation which is the body’s response to any insult such as injury or infection. Thus, the initial blockage was due to this swelling. The swelling would be long gone by now. The attachment now could have happened as the surgeon said although I have never seen such a case. One can function quite well on only one open nostril.

As regards the Strep. throats, penicillin or amoxycillin are very good at treating them. However, your son may be a carrier – when the bugs live in the throat area but do not cause disease. But if he has a virus infection in the throat, like a common cold, this changes conditions in the throat in such a way that the Streps can multiply and then they cause disease. I had some success in getting rid of the carrier state by giving an antibiotic called lincomycin (or its close relative Dalacin-C) while the patient is well.

If the Strep. throats continue, consideration would have to be given to removing the last 10% of the tonsils.

By the way has your doctor proven that the sore throats are due to Strep. by swabbing the throat for laboratory investigation? It can be difficult to tell the difference between a viral throat and a Strep. throat.

Crohn's Disease

I have a 15yr.-old diagnosed as Crohn’s disease 5 years ago. Her bowels were impacted and she spent 5 days in hospital to clean her out for scoping. After 3 years of medicine she saw another Dr. who said she didn’t have Crohn’s because she suffers from constipation and not diarrhea. What do you think?

The 3 most common symptoms of Crohn’s disease are diarrhoea, abdominal (tummy) pain and weight loss. However, it is well known that diarrhoea may not occur. One quarter of Crohn’s sufferers have anal fissures(cracks) which make using the bowels painful. As a 10-year-old, your daughter may have been holding on and not using her bowels because of the pain. This would lead to constipation.

I would be most uncomfortable arguing with a diagnosis of Crohn’s disease made on scoping her bowel, especially if a biopsy of the bowel was taken.

Did she improve with her medication for Crohn’s? If so that is strong evidence that the diagnosis was correct. I gather that the medication was stopped 2 years ago. If she remains well since stopping that does not say the diagnosis was incorrect as Crohn’s has times when it is quiet with no symptoms only to flare again later.

I wish your daughter luck with this unpleasant disease. She needs regular medical review as the symptoms and signs of Crohn’s can be elsewhere than in the gut. Poor weight gain or actual loss may be the main sign in children.

Acne

My son has terrible pimples, and no creams seem to cure or prevent them. His confidence is down, as are his school grades and his self-esteem. He thinks he is ugly and that he’ll never attract girls. Can they be cured, and what can I do to help his emotional problems?

I feel sorry for your son – many of us can remember how miserable pimples made us feel. As you’ve found, creams and ointments are next to useless. He should not squeeze his pimples as this leads to more pimples forming.

Because of the psychological problems you describe, further treatment is needed. Ask your doctor to consider prescribing a daily antibiotic for your son. If that is not successful, ask for a referral to a dermatologist because there is a very effective (but expensive) medication that he/she can prescribe.

Usually, effectively treating the acne (as pimples are called) will improve his psychological health. It may help to have an adult who suffered bad acne talk to your son, especially if he has a photo showing his pimples. He will be able to assure your son that he will eventually grow out of the problem.

Appendicitis

A surgeon has told me that my 10 year-old daughter should have her appendix removed because of repeated tummy pain. He said she had a “grumbling appendix”. My local doctor says there is no such thing. What is your take on this?

The party line in medicine is that there is no such thing as repeated appendicitis. Appendicitis is an acute illness with pain starting around the belly button and then moving to right side of the lower abdomen (tummy).

Having said this, I have met many people who swear that having their appendix out cured their repeated pain.

Children tend to have tummy pain with illnesses elsewhere in the body - for example, with sore throats. It is rather like adults developing headache when unwell from something that is not in their head. I would ask your local doctor to give her a thorough going over in the next episode i.e. look carefully at her Ear, Nose and Throat and other body systems as well as the tummy. A urine sample to exclude infection would be useful as 1% of girls her age suffer urinary infection and this can be a cause of abdominal pain.

Just as adults have headaches with stress, children suffer their stress pain in the tummy. The major causes of stress at this age are a problem at school, e.g. bullying, or problems between the parents which cause the child to want to stay at home and keep an eye on things. Migraine can cause abdominal pain rather than headache in children.

Thus, there are many things to be checked before a child should be subjected to an operation for repeated tummy pain.

Tonsillitis

I took my 6 year-old daughter to the doctor because of her sore throat. She said my daughter had tonsillitis, and swabbed her throat for the laboratory. My daughter has been given antibiotics to start immediately but I am to telephone for the laboratory result in 2 days’ time. Can you tell me about tonsillitis and why the throat swab was necessary?

Tonsillitis is a common infection of the tonsils in the throat. In about half of the cases the infection is due to a bacteria called Streptococcus, in the other half it is due to a viral infection. Your doctor can make the diagnosis of tonsillitis by seeing pus on the tonsils but cannot tell whether it is bacterial or viral. The laboratory will do that by culturing the swab.

Because there is a 50% chance that it will be the Streptococcus it is reasonable to start antibiotics. If it is due to the Streptococcus then a longer than usual course of antibiotic will be given.

In cases of tonsillitis it is important to tell the doctor if there is any family history of rheumatic fever because the Streptococcus can trigger this serious disease in those who are genetically predisposed. This aggressive approach demonstrated by your doctor has helped to make rheumatic fever uncommon in first-world countries.

Repeated tonsillitis will prompt your doctor to suggest having the tonsils removed. Otherwise tonsillitis is just an unpleasant infection except in those who are liable to develop rheumatic fever because there is a family history of it.

Introduction

This blog is to provide answers to questions from parents about childhood illnesses.

I’m David Robinson, a recently retired paediatrician, and I ran a successful and popular Q&A press column for some years.

I’ve always believed it’s better to answer the questions asked by parents rather than write articles about what I think they want to know.

I have six children, now adults, and three grandchildren.

To get the ball rolling, I’ll feature some answers to questions I’ve received in the past.

If you want to ask a question, or require a more detailed follow up question or answer is needed, please email me. I look forward to your questions!
