RESUMO
Fetomaternal hemorrhage induced by intraplacental choriocarcinoma is considered to be extremely rare. We herein describe a neonate with severe anemia caused by intraplacental choriocarcinoma that was histopathologically identified after birth. Furthermore, we reviewed three other such cases in Japan. As a result, the incidence of intraplacental choriocarcinoma may be higher than previously estimated. Therefore, we suggest that the placenta should be examined in any suspected cases of fetomaternal hemorrhage.

It is well known that sports and physical exercise affect the hemoglobin (Hb) concentrations; however, the factors affecting the hematological changes after intense exercise are still not fully elucidated. In the present study, we examined the hematological and biochemical parameters of nine young male soldiers participating in a 12-week ranger training program. The platelet counts before the training showed a strong in-verse correlation with the Hb concentrations after the training (r = -0.829, p < 0.01). Furthermore, the Hb concentrations of the subjects whose platelet counts were more than 25.0 x 10(4)/microL decreased significantly after the training (p < 0.05). Our findings suggest that an association exists between high platelet counts even within the normal range before strenuous physical training and the risk of a subsequent decrease in the Hb concentrations.
