A case of mesoblastic nephroma in a 14-month-old girl who developed consecutive metastases in the lung and the heart is presented. This tumor is considered to be benign and cured by surgery only. Recurrent cases are extremely rare and usually related to unclear surgical margins. Metastatic mesoblastic nephroma has been previously described in only two cases. The present case highlights a new, previously undescribed feature--the ability to metastasize to sites other than lung.
The first Hb S (Hb S trait) inIndonesia, was found by Lie-InjoLuan Eng (1956) in Jakarta. Asfar as we know the case presentedin this paper, is the first patient withthalassemia-Hb S disease ever foundin the Indonesian literature.
The prevalences of hepatitis B surface antigen (HBsAg) and antibody to HBsAg (anti-HBs) were determined in blood donors and transfusion recipients in Jakarta, Indonesia. In blood donors the prevalence of HBsAg was 10% while anti-HBs was 43%. In transfusion recipients the prevalence of HBsAg and anti-HBs was 67%. The prevalence of susceptible recipients or those without detectable HBsAg or anti-HBs was 33%. Thus, the probability that a susceptible recipient would receive HBsAg from a blood donor was calculated at 3.3%. Published data from other studies were used to estimate the risk of clinical post transfusion hepatitis in Jakarta at between 0% and 2%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
