Over at the NCBI ROFL blog, we've learned about a crucial medical research paper recently published in a scientific journal: A study of seven leeches removed from six people's nostrils. Do the math. Yuck. One leech was 12 cm long!
From the European Archives of Oto-Rhino-Laryngology:
Nasal leech infestation rarely occurs in society today and it is usually reported as an anecdote. In this study, we present seven nasal leeches in six patients from 1984 to 2008… Four patients were less than 8 years old and two patients were older than 60 years old. All patients had spent time in rural streams 2 weeks to 2 months before the symptoms occurred. All of the seven leeches were removed smoothly and one leech migrated to the oropharynx during the operation. The length of the leeches ranged from 2 to 12 cm with an average length of 4.6 cm. Attention should be given to nasal leech infestation, especially in children and senior citizens who have visited rural streams and have been exposed to freshwater. One of our patients had two leeches lodged in his nasal cavities. Therefore, it is also important to re-examine both nasal cavities after the removal of one leech.
Well that's just prudent.
