Recent update on reading disability (dyslexia) focused on neurobiology
Sung Koo Kim
Clin Exp Pediatr. 2021;64(10):497-503.   Published online March 2, 2021
·Neurobiological studies using functional brain imaging have uncovered the reading pathways, brain regions involved in reading, and neurobiological abnormalities of dyslexia.
·An accurate diagnosis and timely specialized intervention are important in children with dyslexia. When national infant development screening tests have been conducted as in Korea, if a language developmental delay and early predictors of dyslexia are detected, the progression to dyslexia should be carefully observed and early intervention provided.

Question: Can the Korean Developmental Screening Test for Infants and Children (K-DST) be a useful screening tool for infants and children in Korea?
Finding: The K-DST has high reliability (internal consistency of 0.73–0.93, test-retest reliability of 0.77–0.88) and a high discriminatory ability with a sensitivity of 0.833 and specificity of 0.979.
Meaning: The K-DST is an effective and reliable screening tool for infants and children with neurodevelopmental disorders in Korea.

Recent update of autism spectrum disorders
Sung Koo Kim
Clin Exp Pediatr. 2015;58(1):8-14.   Published online January 31, 2015

In patients with a language developmental delay, it is necessary to make a differential diagnosis for autism spectrum disorders (ASDs), specific language impairment, and mental retardation. It is important that pediatricians recognize the signs and symptoms of ASDs, as many patients with language developmental delays are ultimately diagnosed with ASDs. Pediatricians play an important role in the early recognition of...

Case Report
A case of idiopathic isolated hypoglossal nerve palsy in a Korean child
Ji Hoi Yoon, Kyung Lae Cho, Hae Jung Lee, Seo Hui Choi, Kyung Yul Lee, Sung Koo Kim, Jun Hwa Lee
Clin Exp Pediatr. 2011;54(12):515-517.   Published online December 31, 2011

Hypoglossal nerve palsy (HNP) is an uncommon neurological abnormality that can provoke characteristic clinical signs, including unilateral atrophy of the tongue musculature. We present the case of a healthy 11-year-old Korean male who was admitted to the outpatient department of our institution with acute onset dysarthria, tongue fasciculations, and right-sided tongue weakness upon awakening. His evaluation included a virology work-up,...

Clin Exp Pediatr. 2007;50(8):789-793.   Published online August 15, 2007
Basal cell nevus syndrome (BCNS), also known as Gorlin syndrome, is a rare autosomal dominant disorder characterized by variable manifestations, including multiple basal cell carcinomas, odontogenic keratocysts of the jaw, skeletal anomalies including scoliosis and bifid ribs, palmar and plantar pits, calcification of the falx cerebri, and biparietal frontal bossing. We report a case of a 9-year-old boy with the...

Comparison of neonatal outcomes between the spontaneous and in vitro fertilization twin pregnancies
Hee Moon Kim, Jeong Won Lee, Seon Hee Shin, Sung Koo Kim, Tae Jung Sung
Clin Exp Pediatr. 2007;50(8):740-745.   Published online August 15, 2007
Purpose : There is a dominant opinion that in vitro fertilization (IVF) leads to an increased incidence of twins, low birth weight (LBW) infants, prematurity and mortality. On the other hand, technical development of IVF and improvement of neonatal intensive care have increased the survival rate of neonates. The purpose of this study was to verify the tendency by comparing...

A Case of Rhizomelic Chondrodysplasia Punctata Occurring in Siblings
Soon Hwa Yoon, Nam Young Kim, Seon Hee Shin, Sung Koo Kim, Kon Hee Lee, Hae Sun Yoon, Jung Eun Kim
Clin Exp Pediatr. 2004;47(9):1016-1019.   Published online September 15, 2004
Chondrodysplasia punctata is a group of heterogeneous bone dysplasia characterized by punctate calcifications of the cartilage, frequently associated with a shortening of the limbs, cataracts, icthyosis and alopecia, alterations of the nervous system, and mental and growth deficiencies. Our case presented findings of the rhizomelic chodrodysplasia punctata : a characteristic face, a sucking difficulty and a short neck. Skeletal radiographies...
A Case of Kikuchi-Fujimoto Disease, Subsequently Evolving to Systemic Lupus Eyrthematosus

Clin Exp Pediatr. 2004;47(8):904-907.   Published online August 15, 2004
Kikuchi-Fujimoto disease(KFD), also known as histiocytic necrotizing lymphadenitis, is a self-limited systemic illness and it has the pathognomonic histological appearance of lymph nodes. KFD is rarely associated with systemic lupus erythematosus (SLE). The diagnosis of KFD can precede, postdate or coincide with the diagnosis of SLE. Our case describes a young woman, originally diagnosed as having Kikuchi's disease by lymph...

Clin Exp Pediatr. 2004;47(8):855-860.   Published online August 15, 2004
Purpose : This study was performed to characterize clinical features of benign convulsions with acute gastroenteritis(CwG) in infants. Methods : We reviewed 83 consecutive seizures in 42 patients with CwG between January 1995 and December 2003. CwG was defined as convulsions having the following two characteristics : (a) seizures accompanied with symptoms of gastroenteritis without clinical signs of dehydration or electrolyte...

A Case of Tyrosinemia Type 1 with Cytomegalovirus Infection
Jin Hyung Cho, Kyu Jin Shim, Sung Koo Kim, Seon Hee Shin, Kon Hee Lee, Hae Sun Yun
Clin Exp Pediatr. 2004;47(1):111-114.   Published online January 15, 2004
Tyrosinemia type 1 is an autosomal recessive inborn error of tyrosine metabolism that caused a mutation in the gene coding for the enzyme fumarylacetoacetate hydrolase(FAH). As a result, maleylacetoacetate(MAA) and fumarylacetoacetate(FAA) are formed. The accumulated FAA is converted into succinylacetone(SA) and succinylacetoacetate(SAA) which are excreted in urine. The first report with typical clinical and biochemical findings was presented by Sakai...

Sung Koo Kim, Young Jun Kim, Young Ah Lee, Ha Joo Choi, Woo Kap Chung
Clin Exp Pediatr. 1997;40(7):999-1003.   Published online July 15, 1997
The “band heterotopia” or “double cortex” is a brain anomaly that is presumed to result from a premature arrest of neuronal migration. Generalized disorders of neuronal migration to the cerebral cortex have been recognized since the end of the 19th century. Recently, development of neuroimaging technique, such as MRI, have permitted easy diagnosis of generalized neuronal migration disorder. This syndrome is prevalent in females. Most...
