WARNING! THIS POST IS NOT FOR THE FAINT OF HEART (ie – Rory S. and Bret R., do not read, and definitely do not look at the pictures) Clinic here in Danli tends to be very busy on Mondays and Fridays, while the middle of the week can be fairly quiet. Many of the patients travel a full-day (if not more) to reach the clinic, and therefore, attending the clinic in the middle of the week simply isn’t feasible as it would require missing two days of work. This past Friday was particularly busy… and full of some excellent cases. We had a gentleman with chronic prostatitis (first case of the day), a young kid with fungal infections and superimposed cellulitis and impetigo, as well as a nail extraction for an
ingrown toe nail, among many others. However, the case of the day – and possibly the case of the month – was our first case of myiasis – more commonly known as bot fly; or here in Honduras, “el torsalo.” Myiasis is actually an animal or human disease caused by parasitic dipterous fly larvae that feed on the host's necrotic or living tissues. The fly larvae burrown into human flesh, takes up residence, and builds a nice little home. The burrow forms a hard nodule with a soft, fluctuant center through which the larva is able to breath. As such, common mechanisms of removing the larva
include covering the opening with raw bacon or Vaseline and waiting for the larva to emerge from its den in an attempt to breath. However, if this fails, there is always the option of using a subcutaneous anesthetic injection and manually removing the larvae from its home.
We had a mid-40 year old female present to the clinic today with a nodule on her back, which had been bothering her for some months now. The nodule was hard and indurated, but the center
was soft and fluctuant. She thought she had an infected pimple (espinilla), but she was unsure. Whatever the crater on her back was, we needed to incise it and drain it as it wasn’t going to heal without removing the contents. Without further ado, Dan and I began to prep the lady’s back (of course using sterile technique) in preparation for our excavation. We were suspicious that the nodule might contain a bot fly, but we were not sure. Lo and behold, once I broke skin and opened up the soft center of the crater, the little monster’s head popped out. I quickly grabbed it with my forceps (which was a mistake), because as soon as the larva was out, a rocket of pus shot out of the large abscess on her back. Needless to say, we quickly drained the abscess, packed it, and bandaged the patient up. We were able to provide her with antibiotics to cover the underlying bacterial infection that was brewing, as well as pain medications, and she has returned twice for repacking and dressing changes.
It is incredible that this sort of infection is really not a big deal to the folks living here – it is simply part of life. She was calm and collected the whole time, even when she realized that indeed, a fly larva had made its home in her back and was feeding on her. When we finished the procedure, she thanked us and told us she would be back to have the dressing changed. Not once did she question the diagnosis, nor give indication that she was disturbed by her infection. She was truly a trooper. This again serves as an incredible reminder to just how blessed we are. These are the cases that you hear about in medical school, but are told you will never see because they just don’t occur. Life here is different, and all of those things we shouldn’t see, we are seeing. Hopefully as the country continues to develop, health care will continue to improve, and tropical diseases such as these will become much less common. In the meantime, hand me a scalpel and I'll manually extract the critters!
