Three myths in paediatrics
Have you ever heard these phrases or said them yourself? "The child has such yellow snot, it's probably something bacterial!" "The urine smells so bad, it's probably a urinary tract infection!" "The child is coughing so badly, it must be pneumonia!" You hear all these sentences over and over again and they are all, you guessed it, rubbish.
Firstly, the colour of snot or other secretions that run out of the child's nose or eyes does not indicate whether viruses or bacteria are the cause. Snot can be watery, yellowish or greenish in colour - the decisive factor is the overall condition of the child. These secretions usually contain various viruses and bacteria, but this plays no role in whether or not antibiotic treatment is given.
Secondly, urine can smell for countless reasons. Very often it smells because it is a little too concentrated, i.e. it has not been drunk enough. The odour alone is absolutely not an indication of a urinary tract infection. There are certain physical symptoms and a urinary tract infection requiring treatment also requires a certain poor general condition.
Thirdly, there are perhaps a few real medical freaks who have a mega-well-trained ear and who can make a suspected diagnosis of pneumonia based on the sound of the cough. In general, however, the sound of the cough is completely meaningless when it comes to diagnosing pneumonia (unlike asthma or croup, for example). A child can be almost completely healthy and have a loose, mucousy cough that sounds terrible. However, a child can also have very severe pneumonia and barely have a cough or a completely unremarkable coughing sound.
The bottom line is that all three sentences belong in the realm of myths. They have no validity and are not helpful in assessing your child's state of health.
Further interesting tips
School readiness
When should my child start school? This question is on the minds of many parents every year. Especially if their child's birthday is after the deadline for school enrolment. The solution is complex, but there are pointers that make the decision easier.
Crawling
This will not be an excursion into the realm of insects, crawling is at least as big an issue for parents of small children. Two questions always take centre stage: When should a child crawl? And does a child have to crawl at all?
Blood in the stool
We are starting the new year with a not so appetising topic: blood in the stool. It happens once a week in our day-to-day practice that we receive a very excited phone call or a somewhat panicked email saying: "Oh God, my child has blood in their stool." In most cases, the excitement is unnecessary.
