 Case study for TWiP 106

This week's case comes from an ophthalmologist colleague Florian in Switzerland. Swiss female, early 20s, returns after surfing vacation in northern Africa. Accommodations were rustic, lots of animal and insect exposure, right on the beach. No screens. Had loose stools there, now left eye is bothering her, eyelid swollen, eye red. This happened after return. Thinks she has seen things moving around in her eye. Opthalmologist gave eyedrops, now looking for second opinion. Healthy, no med/surg/allergies, no meds, student lives alone, occasional alcohol. No AIDS. Surfing in Morocco. Lots of insect bites. Little tiny things moving around in eye, on surface when she looks in mirror. All blood work was negative. Florian inspects her eye, surprised to see several tiny mobile objects, headed towards lacrymal ducts. Is able to grab one, about 1 mm long, plucks three off.

 Case study for TWiP 105

This week's case involves a 32 yo male with several concerns. Spent 6 weeks doing religious missionary work in Kenya, performed baptisms in Lake Victoria.Waist deep in water, no shoes. Took malaria drugs, ate lots of interesting foods: cichlids, ugali, corn based food, flavored with greens; stew with some sort of meat, beef and goat. Five weeks after return developed rash with fever, shortness of breath. Three of four friends who were with him in Kenya reported similar symptoms. The fourth who did not get sick did not go in water, nor did he eat very much. No medical/surgical history, no drugs. Had some sexual activity while there. Elevated white count, 70% eosinophils. Chest CT shows nodules in lungs. Doc told him, allergy, you will be fine. The water he went into is near a village, there are rodents nearby, and a runoff.
