There are very few reports and limited evidence that premedication with steroids decreases early recurrence of ileocolic intussusception after a successful hydrostatic reduction. The purpose of this study was to examine the role of steroids in decreasing early recurrence of idiopathic intussusceptions. A retrospective review of children that underwent successful hydrostatic reduction was conducted. Two groups were identified: group 1 (38 cases) that received intravenous methylprednisolone (1 mg/kg/dose) on diagnosis or immediately after the reduction maneuver, and group 2 (59 cases) were not given. There were 60 boys and 37 girls ranging in age from 6 to 84 months. There were no statistical differences between the groups regarding age, sex, duration of symptoms and laboratory findings on admission. There was no significant difference (p=0.76) in the rate of early recurrent intussusception between the steroid group (15.8%, 6/38) and the non-steroid group (13.6%, 8/59). We found that premedication of children with idiopathic intussusception with methylprednisolone did not decrease early recurrence of idiopathic intussusceptions.

The aim of this study was to determine the effect of acute respiratory viral infection on Kawasaki disease. From July 2016 to June 2018, among the patients who underwent respiratory virus screening at the Kwangju Christian Hospital, those diag-nosed 88 patients with Kawasaki disease were enrolled in this study. The effects of acute respiratory viral infection on Ka-wasaki disease were compared according to whether 2nd intravenous immunoglobulin (IVIG) treatment was administered or not, and whether coronary artery complications occurred. Respiratory virus was detected in 44 out of 88 patients. 2nd IVIG treatment rates were 16% (n=7) and 27% (n=12) in the virus positive group and the virus negative group, respectively (p>0.05). The incidence of coronary artery complications was 11% (n=5) and 25% (n=11) in the virus positive group and the virus negative group, respectively (p>0.05). There was no statistically significant correlation between the 2nd IVIG admin-istration and coronary artery complications following the detection of respiratory virus in patients with Kawasaki disease. We think it is necessary to actively study the effects of acute respiratory viral infection on Kawasaki disease through large-scale studies of multiple centers in the future.

There are reports that inhaling hypertonic saline with bronchodilator is helpful in the treatment of bronchiolitis. However, further studies are needed to determine if it is helpful to inhale hypertonic saline with bronchodilator in children with recurrent wheezing. We aimed to investigate the effect of hypertonic saline inhalation in children with recurrent wheezing. A total of 40 patients under 6 years of age admitted to Kwangju Christian Hospital from December 2014 to May 2016 were enrolled. Patients were randomly assigned to receive salbutamol. In the control group (n=21), salbutamol (2.5-5 mg / 0.5-1 mL) was inhaled four times a day with physiological saline (0.9% normal saline 1-3 mL). In the experimental group (n=19), the same amount of hypertonic saline (5% saline 1-3 mL) was inhaled four times a day instead of physiological saline. We compared the duration of wheezing remission between patients who had recurrent wheezing (n=40). There was no difference in the duration of wheezing remission in patients who had recurrent wheezing. But the hypertonic saline inhalation group had a lower post treatment clinical score on the 2nd-3rd day of admission than the physiological saline inhalation group. In this study, hypertonic saline inhalation therapy was not significantly effective in the treatment of recurrent wheezing. More additional research is needed to determine whether inhaled hypertonic saline is effective in the treatment of recurrent wheezing.
