Question: What are the risk factors for prolonged diarrhea in children under 2 years old? Finding: History of antibiotic use, zinc deficiency, and elevated fecal alpha-1 antitrypsin levels were the main risk factors of prolonged diarrhea in children under 2 years old with acute diarrhea. Meaning: Rational antibiotic usage is necessary as well as thorough testing of serum zinc level and fecal alpha-1 antitrypsin levels. |
Question: What is prevalence of bacterial pathogens causing sepsis and their antimicrobial susceptibility over 20 years? Finding: Coagulase-negative remains most common causative organism. The most common gram-negative organism was Klebsiella pneumonia. The susceptibility of staphylococcus aureus and K. pneumonia showed increased susceptability to oxacillin, cefotaxime and amikacin, gentamicin, respectively. Meaning: Answers to the question asked is important in choosing antimicrobials and to monitor emergence of multidrug-resistant organisms. |
Question: How has the antibiotic susceptibility of urinary pathogens changed and what does it imply? Finding: A yearly increase in multidrug-resistant and extended-spectrum β-lactamase (ESBL)–producing pathogens was observed. A higher recurrence rate was observed in cases of febrile urinary tract infection caused by ESBL producers in patients with underlying vesicoureteral reflux (VUR). Meaning: The initial empirical antibiotic should reflect the changing susceptibility patterns and underlying VUR status. |
Inappropriate antibiotic use is the most important factor causing increased bacterial resistance to antibiotics, thus affecting patient outcomes. Multidrug-resistant bacteria have become a serious public health threat, causing significant morbidity and mortality worldwide. In Korea, the burden of antibioticresistant bacteria has become an important public health issue. There is increasing evidence of overuse and misuse of antibiotics in Korea, as... |

Pyogenic liver abscess (PLA) is rare in healthy children. We report a case of PLA in an immunocompetent 12-year-old boy. Percutaneous catheter drainage was performed for the abscess. In addition, parenteral antibiotics were administered for 3 weeks. |
Pyogenic liver abscesses are rare in children. In pediatric patients, altered host defences seem to play an important role. However, pyogenic liver abscess also occurs in healthy children. We experienced a case of pyogenic liver abscess in a healthy immunocompetent 10-year-old-girl. The patient presented two distinct abscesses: one subphrenic and the other intrahepatic. The intrahepatic abscess resolved with percutaneous drainage... |

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... |

Purpose : Urinary tract infection(UTI) is one of the most frequent infections in children. E. coli is the most frequent etiological micropathogen in pediatric community UTI, and E. coli has developed resistance to many antibiotics, highlighting the need for regular surveys of this organism resistant patterns in the community. The aim of this study was to determine the oral antibiotic... |
Purpose : The mortality rate of neonatal sepsis has been decreased, however, the incidence has not significantly decreased because of increased invasive procedures. This study was designed to make guidelines for choosing antibiotics by analyzing the causative microorganisms and their antibiotics sensitivity test according to the onset of neonatal sepsis. Methods : One hundred seven cases of culture proven sepsis... |

Methods : We retrospectively analyzed the major causative organisms and their antibiotic sensitivities in 69 patients diagnosed with UTI in the Department of Pediatrics, Samsung Cheil Hospital... |
Purpose : Bacteremia in immunocompromised pediatric cancer patients can lead to high morbidity and mortality, if not treated early and properly. The incidence and antibiotic sensitivities to common pathogens of bacteremia in pediatric cancer patients are liable to change, according to region and time. We investigated the causative organisms and antibiotic sensitivities of bacteremia in pediatric cancer patients to assess... |
Acute diarrhea is one of the most common diseases that are seen in pediatric patients. In the management of acute diarrhea, several differential diagnostic criteria should be considered based on clinical and/or laboratory findings. These criteria include : ① normal variant stool versus diarrhea ② infectious versus non-infectious condition and ③ bacterial versus non-bacterial etiology. The use of antibiotics should... |
Purpose : S. pneumoniae is one of major pathogens of community-acquired respiratory infections. The rate of antibiotic resistance to this organism has increased, and resistance to multiple antimicrobial agents in a single strain of S. pneumoniae may compromise the efficacy of empiric antimicrobial treatment commonly used for respiratory infections. We did this study to find out the penicillin resistant distributions... |
Purpose : Advances in the treatment of congenital heart disease and a decline in the incidence of rheumatic fever has led to changes in the causative organisms and the clinical outcome of infective endocarditis(IE). We sought to analyze the clinical outcome, prognostic factors, causative organisms and corresponding antibiotic sensitivity in IE.
