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
