School is back in the session which is a blessing for many of us parents who are happy to see some structure back into the day. As the kids run and play at school, it also provide opportunity for those pesky head lice to party.
I recall all too vividly last year when within weeks of school starting, I looked down by daughters head and saw something moving around. I knew right away it was head lice. Of course my wife totally freaked out. We took care of it right away.
While head lice are annoying, they cause no medical harm. They cross all socioeconomic boundaries. Over the summer, the AAP updated its policy on head lice. The policy states “Head lice are not a health hazard or a sign of poor hygiene and, in contrast to body lice, are not responsible for the spread of any disease”. It also goes on to state that “No healthy child should be excluded from or miss school because of head lice, and no-nit policies for return to school should be abandoned. Informed school nurses can help with diagnosis and suggestions about treatment”. I realize that this second statement may be in stark contrast to school policies currently in place.
A quick recap of treatment from a prior blog.
Permethrin 1% is most commonly used and is over the counter. It is quite effective and safe with a low potential for toxic effects. It continues to work for a few weeks after application although often a second treatment is recommended 7-10 days after the first one. Resistance to it has been documented.
Malathion in another drug used. It is an organophosphate pesticide that is highly effective but has some safety concerns and is not recommended in children younger than 2 years of age.
Lindane is the last drug I will discuss. It is an organochloride. It has some toxicity concerns and is considered a neurotoxin and has the potential for central nervous system toxicity. It should be the last option after everything else has failed.
Suffocation: There are no great evidenced based data to say whether suffocation of lice by applying things such as petroleum jelly, olive oil, mayonnaise is an effective treatment. This is not to say that it does not work, but just no good studies regarding this.
There was an article in the journal Pediatrics years ago regarding treatment with a suffocating agent that ultimately ended up being Cetaphil. Here is the link: http://www.nuvoforheadlice.com.
