Genetics of hereditary nephrotic syndrome: a clinical review
Tae-Sun Ha
Clin Exp Pediatr. 2017;60(3):55-63.   Published online March 27, 2017

Advances in podocytology and genetic techniques have expanded our understanding of the pathogenesis of hereditary steroid-resistant nephrotic syndrome (SRNS). In the past 20 years, over 45 genetic mutations have been identified in patients with hereditary SRNS. Genetic mutations on structural and functional molecules in podocytes can lead to serious injury in the podocytes themselves and in adjacent structures, causing sclerotic...

Puromycin aminonucleoside modulates p130Cas of podocytes
Tae-Sun Ha, Ji-Young Choi, Hye-Young Park
Clin Exp Pediatr. 2012;55(10):371-376.   Published online October 29, 2012
Purpose

Puromycin aminonucleoside (PAN) specifically injures podocytes, leading to foot process effacement, actin cytoskeleton disorganization, and abnormal distribution of slit diaphragm proteins. p130Cas is a docking protein connecting F-actin fibers to the glomerular basement membrane (GBM) and adapter proteins in glomerular epithelial cells (GEpCs; podocytes). We investigated the changes in the p130Cas expression level in the PAN-induced pathological changes of podocytes...

Antibiotic susceptibility and imaging findings of the causative microorganisms responsible for acute urinary tract infection in children: a five-year single center study
Ji Eun Yoon, Wun Kon Kim, Jin Seok Lee, Kyeong-Seob Shin, Tae-Sun Ha
Clin Exp Pediatr. 2011;54(2):79-85.   Published online February 28, 2011
Purpose

We studied the differences in the antibiotic susceptibilities of the microorganisms that causeing urinary tract infections (UTI) in children to obtain useful information on appropriate drug selection for childhood UTI.

Methods

We retrospectively analyzed the antibiotic susceptibilities of 429 microorganisms isolated from 900 patients diagnosed with UTI in the Department of Pediatrics, Chungbuk National University Hospital, from 2003 to 2008.

Results

The most common...

Clinical study of urinary tract infection, natural courses, and prenatal ultrasonographic results according to the grades of hydronephrosis
Jee-Hee Lee, Jun-Woo Kim, Ji-Eun Yoon, Tae-Sun Ha
Clin Exp Pediatr. 2009;52(8):917-921.   Published online August 15, 2009

Purpose:Although renal ultrasonography (USG) has improved the detection rate of hydronephrosis (HN), its clinical courses and postnatal management remains controversial. Here, we reviewed the clinical features of patients with HN according to the grades. Methods:We retrospectively studied 207 patients who were regularly followed-up among 367 patients with HN detected by renal USG postnatally between April 1998 and December 2007. These patients were grouped...
Case Report
A Case of Hypocomplementemic Henoch-Schönlein Purpura Presenting Features of Membranoproliferative Glomerulonephritis
Kyong-A Lee, Tae-Sun Ha
Clin Exp Pediatr. 2005;48(1):81-84.   Published online January 15, 2005
Henoch-Schönlein purpura (HSP) is a systemic disorder characterized by leukocytoclastic vasculitis that can affect multiple organs predominantly the skin, joints, gastrointestinal tract and kidney. Although the specific pathogenesis of HSP is not known, there are several hypotheses. Although the importance of the complement activation in glomerular injury in HSP has been suggested, the complement levels and the blood pressure in...

Clinical Analysis of Scrotal Involvement in Childhood Henoch-Schönlein Purpura
Jin-Seok Lee, Tae-Sun Ha
Clin Exp Pediatr. 2004;47(10):1093-1099.   Published online October 15, 2004
Purpose : Henoch-Schönlein purpura(HSP) is a systemic vasculitis affecting predominantly skin, the gastrointestinal tract, the joints and kidneys. Because the scrotal manifestations including swelling and pain (or tenderness) are known to be uncommon in male HSP patients, there has been a little mention of them in the studies of HSP. Therefore, we investigated the clinical and laboratory features of HSP...
A Clinical Study of Childhood Henoch-Sch nlein Purpura
Tae-Sun Ha, Hyun-Hoe Koo
Clin Exp Pediatr. 2003;46(11):1118-1123.   Published online November 15, 2003
Purpose : Henoch-Sch nlein purpura(HSP) is a systemic vasculitis, characterized by cutaneous purpura, abdominal pain, arthralgia and renal involvement. The clinical features of HSP have been reasonably well documented but there are still many gaps in our understanding of HSP. The aim of this study was to present the clinical features of 125 children with HSP and compare them with...
Clinical Study of the Correlation of Tumor Necrosis Factor Alpha and the Proteinuria of Henoch-Schönlein Nephritis and Idiopathic Nephrotic Syndrome
Dong-Ho Jeong, Jeong-Hyun Park, Hye-Cheon Jeong, Hyun-Hoe Koo, Jun-Ho Lee, Tae-Sun Ha
Clin Exp Pediatr. 2002;45(2):240-246.   Published online February 15, 2002
Purpose : It is not clear that the development of glomerular injury and aggravation by tumor necrosis factor alpha(TNF-α) is related to intrarenal or serum concentration of TNF-α. So, we studied the relationship between the concentration of TNF-α and aggravation of glomerular damage in the Henoch-Schönlein nephritis(HSN) and idiopathic nephrotic syndrome(INS). Methods : We collected the sera and urines of...
