BACKGROUND The aim of this study was to evaluate the results of ultrasound (US)-guided hydrostatic reduction (UGSED) of intussusceptions in pediatric patients by saline enema. METHODS Five thousand two hundred eighteen pediatric patients with intussusceptions treated by UGSED from October 1985 to October 2002 were reviewed retrospectively. RESULTS The(More)
Castleman disease is a rare benign lymph node hyperplasia usually presenting as an asymptomatic mediastinal mass in children. It can present at any extrathoracic site where there is lymphoid tissue. The sites include retroperitoneum, mesentery, axilla, and pelvis. Mesenteric Castleman disease is very rare in children.
Neuroblastoma (NB) is the most common extracranial solid tumor in children. In this study, we investigated the potential antitumor capability of the engineered Edmonston strain of the carcinoembryonic antigen-expressing measles virus (MV-CEA) against human NB. The infection of a variety of NB cell lines, including SK-N-SH, SMS-KCNR, and primary NB cells,(More)
OBJECTIVES Wilms tumor (WT) is one of the most common solid tumors in children. It also is the most frequent tumor found in the kidneys. In 5% of cases, it affects both kidneys simultaneously. Extrarenal WTs are extremely rare. The diagnosis of extrarenal WT is almost always made after surgical intervention. The tumor can be located in the retroperitoneum,(More)
Thoracoabdominal foregut duplication is a rare congenital abnormality. The authors report a case of thoracoabdominal foregut duplication cyst in a 13-year-old male patient. The pathologic report revealed that a thoracic mass with a pseudostratified, ciliated, columnar epithelial lining (respiratory tract epithelium), an abdominal mass with gastric mucosa(More)

Blood coagulation plays a critical role not only in hemostasis but also in many physiological and pathological conditions. Epidemiological studies have shown that blood coagulation capacity in humans increases with age. Towards understanding the underlying mechanisms, the age regulation of factor IX, a key blood coagulation factor, was extensively studied.(More)
