BACKGROUND: A positive association between birth weight (BW) and body mass index (BMI) has been shown among children in many populations. The aim of this study was to investigate BMI trajectory according to BW status and the protective effect of breastfeeding on the prevalence of overweight/obesity in children 6 years of age. METHODS: A retrospective cohort study was conducted between January 1, 2008 and December 31, 2016 utilizing data from the National Health Information Database of Korea. The

Henoch-Schönlein purpura (HSP) is a leukocytoclastic vasculitis classically characterized by palpable purpura, arthritis, abdominal pain and renal disease. In this article, we summarize our current understanding of the pathogenesis of HSP and the implications for improving its diagnosis. Although the pathogenesis of HSP is not fully understood yet, exciting new information has emerged in recent years, leading to a better understanding of its pathogenesis. Here, we discuss genetic predisposition,

OBJECTIVE: Infection and bone resorption are major complications of cranioplasty and have been well recognized. However, there are few clinical series describing the epidural fluid collection (EFC) as complication of cranioplasty. This study was planned to identify the predictive factors and fate of EFC after cranioplasty. METHODS: We reviewed retrospectively the demographic, clinical, and radiographic data in 59 patients who underwent a first cranioplsty following decompressive craniectomy duri

Delta neutrophil index (DNI) is the fraction of circulating immature granulocytes, which reflects severe bacterial infections and septic condition but has not been studied in urinary tract infection (UTI). Here, we evaluated the value of DNI in predicting acute pyelonephritis (APN) or vesicoureteral reflux (VUR) using the data of 288 patients. Conventional inflammatory markers (white blood cell [WBC] count, erythrocyte sedimentation rate [ESR], C-reactive protein [CRP]), and DNI were measured. W

We report a rare case of fibrous dysplasia with the development of a secondary aneurysmal bone cyst presenting as solitary tumor of calvarium. Although fibrous dysplasia with aneurysmal bone cyst is rare, it should be taken into account in differential diagnosis of the osteolytic solitary skull lesion.

목적: 소아 요로감염은 적절한 항생제 치료가 중요하며 항생제의 선택에는 E. coli에 대한 항생제 감수성이 기준이 된다. Extended-spectrum ${\beta}-lactamase(ESBL)$ 은 E. coli 등 그람음성균에서 분비되어 광범위 항생제 내성을 초래하는 효소로서 주로 병원 감염에서 발생하여 치료를 어렵게 하는 요인으로 알려져 ...

목 적 : 소아 요로감염은 적절한 항생제 치료가 중요하며 항생제의 선택에는 E. coli에 대한 항생제 감수성이 기준이 된다. Extended-spectrum β-lactamase(ESBL)은 E. coli 등 그람 음성균에서 분비되어 광범위 항생제 내성을 초래하는 효소로서 주로 병원 감염에서 발생하여 치료를 어렵게 하는 요인으로 알려져 있다. 저자들은 지역사회 획득 소아 요로감염에서도 ESBL(＋) E. coli가 분리되었기에 ESBL(＋) E. coli요로감염의 특성을 후향적으로 조사하고자 하였다. 방 법 : 2001년 3월부터 2003년 2월까지 이대목동병원 소아과에 입원한 지역사회 획득 E. coli 요로감염 소아(288명)를 대상으로 ESBL을 검사하였다. 검사 방법은 미량 액체배지 희석법을 이용한 자동화 기계(Vitek GNS 433 card)에서 ESBL이 의심되는 균주에 한해 National Committee for Clinical Laboratory Standard
