ABSTRACT

Diagnosis: S. stercoralis

History: A 25 year-old Bolivian woman was brought to the ship by a smaller boat, on the River Mamore. She had diarrhea for one year with green stool increasing to 3-5 dark liquid stools per day over the past month. This was accompanied by malaise, dizziness, weakness and some nausea, with vomiting and anorexia.

Findings: Both microscopic evaluation and digital still images clearly revealed prominent genital primordium and a short buccal capsule characteristic of rhabditoid larvae of S. stercoralis

Ddx: Strongyloides stercoralis In comparison, the most common conflicting diagnosis of hookworm rhabditoid larvae has long buccal capsules and inconspicuous genital primordium.

Dxhow: Wet prep of the stool revealed multiple Strongyloides stercoralis larvae

Exam: On physical examination she was in acute distress, with extreme dehydration and a subdued affect. Her vital signs revealed a temperature of 38 ?C, a pulse of 120 per minute, respirations of 20 per minute, and a palpable blood pressure of 120 mmHG. Signs of severe dehydration included orthostasis, dry mucous membranes, sunken eyes and tenting of the skin. She had a few bilateral course rales, normal cardiac exam, mild diffuse abdominal tenderness, and no hepatosplenomegaly. The remainder of her physical examination was normal. Her rectal exam revealed guaiac positive stool. Urinalysis showed white blood cells but negative nitrite; her hemoglobin was 10.5. Wet prep of the stool revealed white blood cells with multiple Strongyloides stercoralis larvae; no parasite eggs were seen. Her blood smears were negative for malaria.
