Mozambique Man Bit By Human Treated with VisualDx Help


Katherine Vaillancourt, a 2nd year med student at Quinnipiac University, shares how she used VisualDx to treat a patient in Malawi:

An 80 year old Mozambican man presented to a rural Malawian health care center for treatment of a wound on his left arm. He reported being bitten by a human on the volar aspect of his left wrist 3 weeks prior to coming to the hospital. He did not seek treatment as he believed that he was bewitched and this caused him to be bitten. He did use local herbal remedies on the wound which he did not know the names of. Upon presentation to the health center, the man's vitals were stable, though he was febrile, but he appeared to be in acute pain. The bite wound was not distinguishable because the entire left medial arm from the wrist to the mid-bicep was necrotic and oozing pus and blood. The arm was contracted in a flexed position at the elbow and could not be extended actively or passively. (*Necrotized cellulitis on patient's ankle depicted in picture is not the patient in this story.)

Necrotized cellulitis was the primary differential diagnosis, along with other diagnoses including burn, trauma, and gangrene. However, the bite wound could not be appreciated. VisualDx helped to clarify that necrotized cellulitis was our most likely diagnosis and so we treated with broad spectrum antibiotics IV, then orally and topical silver sulfadiazine.
