Update on benign convulsions with mild gastroenteritis
Yeong Seok Lee, Ga Hee Lee, Young Se Kwon
Clin Exp Pediatr. 2022;65(10):469-475.   Published online December 27, 2021
∙ The main pathogen for benign convulsions with mild gastroenteritis (CwG) was previously rotavirus; however, cases associated with norovirus are increasing.
∙ CwG is characterized by clustered generalized seizures. Electroencephalography and magnetic resonance imaging show transiently abnormal findings in the acute phase that eventually normalize with progression. Its prognosis is good, and long-term treatment is unnecessary.
∙ There are many reports on the pathophysiological mechanism of CwG, which remains unclear.

Soon Jeong Moon, Young Min An, Soon Ki Kim, Young Se Kwon, Ji Eun Lee
Clin Exp Pediatr. 2017;60(12):403-407.   Published online December 22, 2017
Purpose

Quadriplegic children with cerebral palsy are more susceptible to osteoporosis because of various risk factors that interfere with bone metabolism. Pamidronate is effective for pediatric osteoporosis, but there are no guidelines for optimal dosage or duration of treatment in quadriplegic children with osteoporosis. We aimed to evaluate the efficacy of low-dose pamidronate treatment in these patients.

Methods

Ten quadriplegic patients on antiepileptic...

Development of multifocal nodular lesions of a liver mimicking hepatic metastasis, following resection of an insulinoma in a child
Sook Young Jung, Ben Kang, Yoon Mee Choi, Jun Mee Kim, Soon Ki Kim, Young Se Kwon, Ji Eun Lee
Clin Exp Pediatr. 2015;58(2):69-72.   Published online February 28, 2015

Insulinoma, which arises from insulin-producing pancreatic beta cells, is a rare tumor in children. Only 5%-10% of insulinomas are malignant and undergo metastasis. We report a case of an 11-year-old girl who experienced hypoglycemia-related seizures induced by an insulinoma; after resection of the primary tumor, she developed hepatic focal nodular hyperplasia (FNH). Laboratory test results indicated marked hypoglycemia with hyperinsulinemia....

Benign convulsion with mild gastroenteritis
Ben Kang, Young Se Kwon
Clin Exp Pediatr. 2014;57(7):304-309.   Published online July 23, 2014

Benign convulsion with mild gastroenteritis (CwG) is a type of afebrile seizure that occurs in children. CwG is defined as a convulsion in a previously healthy child with no known central nervous system infection or encephalopathy, accompanying mild diarrhea without fever, electrolyte imbalance, or moderate to severe dehydration. Convulsions in CwG are characterized by multiple brief episodes of generalized or...

Clin Exp Pediatr. 2005;48(2):228-231.   Published online February 15, 2005
Atypical teratoid/rhabdoid tumor may arise at any central nervous system location, but it is most commonly located in the cerebellum(60 percent). The incidence of this tumor remains unclear but it occurs most commonly in children less than 2 years of age. This highly malignant tumor shows a rapid progression and nonspecific radiologic findings. We report a case of primary intracranial...

A Case of Krabbe Disease with Infantile Spasm
Ja Kyoung Kim, Dal Hyun Kim, Bo Young Kang, Young Se Kwon, Young Jin Hong, Byong Kwan Son, Hye Ran Yoon
Clin Exp Pediatr. 2003;46(1):95-99.   Published online January 15, 2003
Krabbe disease is a rare autosomal recessive disorder clinically characterized by retardation in motor development, prominent spasticity, seizures, and optic atrophy. Pathologically, there are many globoid cells in the white matter, in addition to the lack of myelin and the presence of severe gliosis. Hence Krabbe disease is known as globoid cell leukodystrophy. Biochemically, the primary enzymatic deficiency in Krabbe...
A Case of Rhizomelic Chondrodysplasia Punctata Type I
