Loiasis is a parasitic illness that is endemic in parts of Central and West Africa. In the United States, infection with Loa loa is seen in natives from that region of Africa and in those who have traveled to the area, often in the distant past. There can be significant differences in clinical manifestations between the two groups. We present a case of loiasis in an African native as well as a discussion of Loa loa infection in natives and non-natives and current treatment strategies.

To assess the effect of a 33% coronary stenosis on myocardial blood flow during normal sinus rhythm and CPR. ⋯ Minimal coronary lesions that do not diminish myocardial perfusion during normal physiologic conditions appear to significantly decrease subendocardial blood flow during cardiac arrest and CPR.

To demonstrate the technique of selective aortic arch perfusion during cardiac arrest and to observe the hemodynamic effects of volume infusion and aortic epinephrine administration. ⋯ Selective aortic arch perfusion is technically feasible, but excessive right atrial pressure increases limit maximal infusion rates and volumes. Selective aortic arch perfusion infusates with epinephrine produce greater midaortic arch pressure and coronary perfusion pressure during infusion than infusate without epinephrine. Controlled studies are needed to determine if selective aortic arch perfusion improves resuscitation outcome.
