Medicine is an ever-changing area. This is not because we have so much knowledge, contrary, we
know very little. In Pubmed, there are more than 28 million citations. But for a randomized controlled
trial with a head-to-head comparison between tramadol and naproxen for pain relief in those with
osteoarthritis, we know none. Or even for the route of magnesium sulfate in those with preeclampsia,
preferred administration route to achieve the therapeutic level is unknown. You can find
the answers to the two questions above in this issue. Moreover, you will also find the new invention
for diagnosis of cholangiocarcinoma using antigen of its own tumor and case series of infants with
gastroschisis. Hope you enjoy reading our journal.
