Is human myiasis in rural South Africa under-reported?
Myiasis is a more common medical condition than expected in the Mthatha region. The study shows that human myiasis is still frequently encountered in SA, and there is a need to understand its epidemiology better.
In this study, the decrease in blood reperfusion at 1h measured by B-flow USG was apparently higher than that measured by Doppler USG. However, by the end of 2h, the measurements were equal (see Fig. 3 and 4). In conclusion, B-flow USG reveals the decrease in the blood flow more distinctly in the early phase. Moreover, B-flow Doppler USG is more reliable and advantageous than color Doppler USG because it provides a more accurate preoperative evaluation of the unilateral and contralateral preoperative adnexial structures, and allows for a better assessment of blood flow in the ovarian torsion.
