An Unusual Sneeze
Many years
ago I, in conjunction with my family, started to grade sneezes on a scale of one
to ten according to the noise generated. This quickly developed into a
competition to see who could sneeze the loudest. A rating of five or six would
be what most people would consider normal with lower numbers reserved for the
more discreet. On the other hand, between eight and ten would be considered
sufficiently loud to make other people’s ears bleed or to knock over small
children.
The sneeze in this story, however, was unusual
not because of its volume, but because of the product - I am not talking about
snot or blood here, or even a bead previously inserted into a nostril by a
small child and subsequently sneezed out. A lady came to one of our rural
clinics asking for some worm medicine – we routinely prescribed this to young
children as hookworm infestation is common in Cambodia as a result of them
walking barefoot on contaminated soil. The larvae penetrate the skin of the foot and then
enter the lungs via the bloodstream. From here they are coughed up into the
throat, swallowed, and enter the intestine.
It is not uncommon for affected people to see the worms in their stools, but in
many cases there are no specific symptoms. Nevertheless, anaemia is a common
result because the worms in the intestine feed on blood. However, when we asked
this patient how she knew she was infected, she explained that she had recently
sneezed a worm out of her nose! On another occasion I saw a patient who woke up
one morning to see a worm lying on the pillow next to her head which had,
presumably, been coughed up while she was asleep.
Fortunately,
the infestation is simply treated with an antihelminthic such as albendazole
which can be swallowed or chewed. Health education to help break the lifecycle of the parasite is also important, especially the wearing of footwear outdoors particularly when there are a large number of dogs and cats around as these are the definitive hosts.
