Injection & Bioresponse


Pediatricians are a “general physician” who manage various diseases from the fetus to the AYA generation. Furthermore, they are also involved in the field of child health, which has become a major social problem such as child abuse. It is an important role for us not only to cure children with mental and physical problems, but also to care and manage the development of healthy children.
Our department consist of 10 clinical groups and 5 research ones. To aim new strategies for treatment and improvement of QOL with affected children, we always continue to make efforts in the field, from genetic analysis to field work. There is a special education course for medical students. Also, we have some training courses for postgraduate doctors. We all guide younger doctors to get evidence based-medicine and communication skills.

Clinical Activities

As a tertiary referral center, our Department of Pediatrics provides the highest level of pediatric care. The Department also manages critically ill newborns suffering from a wide variety of diseases in the Neonatal Intensive Care Unit. Thus, our range of services includes treating premature infants, full-term newborns, toddlers, youth, adolescents, and all ages and life stages in between. There are several subspecialty services within the Department; allergy, pulmonology, endocrinology, gastroenterology, genetics and metabolism, hematology, oncology, immunology, nephrology, neurology, child psychiatry, and cardiology. This allows us to have skilled multi-disciplinary teams that work well together to deal with almost any disease or disorder a child may have.
