Clin Exp Pediatr. 2011;54(10):422-424.   Published online October 31, 2011

Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disease of the central nervous system that typically follows an infection or vaccination and has a favorable long-term prognosis. We describe the first reported case of ADEM after vaccination against novel influenza A (H1N1). A previously healthy 34-month-old boy who developed ADEM presented with a seizure and left-sided weakness 5 days after...

Spinal muscular atrophy (SMA) is an autosomal recessive disease characterized by diffuse proximal and distal weakness due to deletion of the survival motor neuron (SMN) gene localized on chromosome 5 (5q11.2-13.3). SMA has been considered as a pure lower motor neuron disorder, and a definitive diagnosis can be established by molecular genetic testing. Here, we describe two patients with severe...

Clin Exp Pediatr. 2004;47(5):567-573.   Published online May 15, 2004
Purpose : Kawasaki disease(KD) is an important acute febrile systemic vasculitis disease. Various cytokines have been studied to evaluate the pathogenesis of vascular injury. Some cytokines have been implicated for vascular injury, but there has been no direct evidence. We compared cytokine profiles of KD with Henoch-Sch nlein purpura(HSP), and febrile infections. Methods : We investigated the serum concentrations of...

Preterm infants(birth weight 500 to 1,350...
Availability of Capillary Blood Gas Analysis in Neonate
Jong Tae Jeong, Su Young Yun, Ran Lee, Jae Ho Hyun, Gyu Young Jung
Clin Exp Pediatr. 2002;45(4):449-453.   Published online April 15, 2002
Purpose : Arterial blood gas analysis is frequently performed in neonatal intensive care unit (NICU) to evaluate ventilation and the metabolic state of critically ill infants. In occasions when umbilical arterial catheterization is not available, frequent arterial puncture is mandatory. This requires some technical skill and may occasionally have side effects. So we studied the validity of capillary blood gas...

Clin Exp Pediatr. 2000;43(2):267-273.   Published online February 15, 2000
Purpose : Seizures during the neonatal period may be an important indicator of serious neurologic abnormalities and can cause permanent neurologic sequelae. We attempted to find and analyze the factors related to the outcome of neonatal seizures. Methods : Seventy-six newborns with seizure were reviewed. The outcomes were analyzed according to etiologic diseases, gestational ages, characteristics of seizure, and neuroimaging and...

Ran Lee, Jeong Kee Seo, Kwi won Park, Jong Je Kim
Clin Exp Pediatr. 1997;40(2):254-259.   Published online February 15, 1997
Ischemic enteritis is caused by embolism or thrombosis of superior mesenteric artery and nonocclusive ischemia. Mesenteric venous thrombosis, drugs, and vasculitis are less frequent etiologic factors. In children, occlusion of microcirculation by fibrin thrombi initiated by endotoxemia may be an etiology. Severe abdominal pain, vomiting, and diarrhea with evidence of gross or microscopic bleeding are common presenting symptoms. Angiography may be...
