Air reduction is a safe, effective, and fast initial treatment for pediatric intussusception. There is low dose radiation exposure. Factors affecting outcomes of air reduction were analyzed by reviewing the clinical features and results of treatment. A total of 399 out of 485 patients with pediatric intussusceptions were treated at the Seoul National University Children's Hospital from 1996 to 2009. All of the patients received air reduction as the first line of treatment. Clinical features such as gender, age, seasonal variation, symptoms, signs, types, pathologic leading point, and treatment results including success rate, complication, recurrence, NPO time, and duration of hospitalization were reviewed. The Pearson chi-square, student T-, and logistic regression tests were used for statistical analysis. P-value less than 0.05 was considered to be statistically significant. The prevalent clinical features were: male (65.4%), under one-year of age (40.3%), ileocolic type (71.9%), abdominal pain (85.4%), and accompanying mesentery lymph node enlargement (2.2%). The overall success rate for air reduction was 78.4% (313 of 399 patients), and the perforation rate during reduction was 1.5%. There were 23 recurrent cases over 21.6 months. All were successfully treated with re-do air reduction. Reduction failures had longer overall NPO times (27.067hrs vs. 43.0588hrs; p=0.000) and hospitalization durations (1.738d vs. 6.975d; p=0.000) compared to the successful cases. The factors affecting success rates were fever (p=0.002), abdominal distension (p=0.000), lethargy (p=0.000) and symptom duration (p=0.000) on univariate analysis. Failure rates were higher in patients with symptom durations greater than 24 hours (p=0.023), and lethargy (p=0.003) on multivariate analysis. Air reduction showed high success rates and excellent treatment outcomes as the initial treatment for pediatric intussusception in this study. Symptom duration and lethargy were significantly associated with reduced success rates.

BACKGROUND AND OBJECTIVES: Respiratory symptoms are often observed in children with Kawasaki disease (KD) during the acute phase. The association of respiratory viruses in children with KD was investigated using multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) and tissue Doppler echocardiography. SUBJECTS AND METHODS: 138 KD patients were included from January 2010 to June 2013. We compared 3 groups (group 1: n=94, KD without respiratory symptoms; group 2: n=44, KD with respiratory symptoms; and group 3: n=50, febrile patients with respiratory symptoms). Laboratory data were obtained from each patient including N-terminal pro-brain natriuretic peptide (NT-proBNP). Echocardiographic measurements were compared between group 1 and group 2. RT-PCR was performed using nasopharyngeal secretion to screen for the presence of 14 viruses in groups 2 and 3. RESULTS: The incidence of KD with respiratory symptoms was 31.8%. The duration of fever was significantly longer, and coronary artery diameter was larger in group 2 than in group 1. Tei index was significantly higher and coronary artery diameter larger in group 2 than group 1. Coronary artery diameter, C-reactive protein levels, platelet count, alanine aminotransferase levels, and NT-pro BNP levels were significantly higher and albumin levels lower in group 2 compared with group 3. CONCLUSION: NT-pro BNP was a valuable diagnostic tool in differentiating KD from other febrile viral respiratory infections. Some viruses were more frequently observed in KD patients than in febrile controls. Tei index using tissue Doppler imaging was increased in KD patients with respiratory symptoms.
