Clin Exp Pediatr. 2010;53(6):722-726.   Published online June 23, 2010

Chronic granulomatous disease (CGD) is an uncommon inherited disorder caused by mutations in any of the genes encoding subunits of the superoxide-generating phagocyte NADPH oxidase system, which is essential for killing catalase producing bacteria and fungi, such as Aspergillus species, Staphylococcus aureus, Serratia marcescens, Nocardia species and Burkholderia cepacia. In case of a history of recurrent or persistent infections, immune...

Two cases of Kawasaki disease following pneumonia
Hyun Jung Kim, Soo Jin Lee
Clin Exp Pediatr. 2009;52(5):615-618.   Published online May 15, 2009
Kawasaki disease (KD) causes multisystemic vasculitis but rarely manifests with pulmonary symptoms. As its etiology is still unknown, there are no specific diagnostic tools available, and KD can be diagnosed only by the symptom pattern. The presence of unusual clinical manifestations often leads to delayed diagnosis. Here, we report two cases of KD with an initial presentation of pneumonia. KD...
A case of fatal pneumococcal 19A meningoencephalitis despite administration of seven-valent pneumococcal conjugate vaccines
Ah Rum Heo, Jun Hwa Lee
Clin Exp Pediatr. 2009;52(4):508-511.   Published online April 15, 2009
Streptococcus pneumoniae is a major cause of serious invasive diseases in children, especially in young infants, but seven- valent pneumococcal conjugate vaccine (PCV7) is believed to prevent invasive pneumococcal pneumonia and meningitis in young children. However, recently, the incidence of non-PCV7 serotype has increased after PCV7 vaccination. A 14-month- old female patient presented at our emergency room with mental change...

Antibiotics for bacterial pneumonia in children
Hye-yung Yum
Clin Exp Pediatr. 2009;52(3):283-288.   Published online March 15, 2009
Pneumonia remains the leading cause of mortality in children. Diagnosis depends on a combination of factors, including clinical assessment, radiological and laboratory findings. Although Streptococcus pneumoniae remains the most important cause of childhood bacterial pneumonia, the great majority of cases of community-acquired pneumonia (CAP) are of viral etiology. A new, rapid, and inexpensive test that differentiates viral from bacterial pneumonia...
Mycoplasma and chlamydia infection in Korea
Kyung Won Kim, Kyu-Earn Kim
Clin Exp Pediatr. 2009;52(3):277-282.   Published online March 15, 2009
Pneumonia, which usually requires hospitalization for children, is caused by various pathogens. According to recent surveys, the prevalence of atypical pneumonia caused by Mycoplasma or Chlamydia has increased, especially in preschool children. Also, the evidence has been accumulated that Mycoplasma or Chlamydia infection is associated with asthma including both inception and exacerbation. Therefore, it is important to consider how the...

Eun Hwa Choi
Clin Exp Pediatr. 2008;51(10):1031-1037.   Published online October 15, 2008
Macrolide antimicrobial agents including erythromycin, roxithromycin, clarithromycin, and azithromycin are commonly used in the treatment of respiratory tract infections in children. Newer macrolides that have structural modifications of older drug erythromycin show improved change in the spectrum of activity, dosing, and administration. However, recent studies reported that increasing use of macrolide antibiotics is the main force driving the development of...

Clin Exp Pediatr. 2007;50(2):151-156.   Published online February 15, 2007
Purpose : Streptococcus pneumoniae is a major etiologic agent for pneumonia, meningitis, otitis media, and sepsis among young children. Multi-drug resistant strains have raised great concern worldwide, thus the importance of prevention with vaccines has been emphasized. However, vaccines may force the appearance of pneumococcal infections by nonvaccine serotypes. Thus, distribution of pneumococcal serotypes should be monitored to estimate vaccine...
