ABSTRACT

Purpose@#We aimed to survey current status of preparedness for neonatal resuscitation in delivery rooms in Korea. @*Methods@#We analyzed data regarding preparedness for the resuscitation in terms of personnel, equipment, and education using a questionnaire, which was developed by the Korean Association of Cardiopulmonary Resuscitation. From August 2020 through January 2021, the questionnaires were sent to hospitals affiliated with the Korean Association of Maternity Hospitals or the Korean Neonatal Network (KNN) operated by the Korean Society of Neonatology. As per the affiliated society, the hospitals were grouped as the maternity hospitals or the KNN hospitals. The questionnaires were delivered in 3 steps: mailout, electronic mail, and phone calls. @*Results@#Response rate was 21.3% (115 of 541) and 65.3% (49 of 75) in the maternity and KNN hospitals, respectively. The maternity hospitals showed a higher mean number of delivery and fewer pediatricians. In the KNN hospitals, pediatricians played a leading role during the resuscitation, but in the maternity hospitals, their role as a leader was less conspicuous. The KNN hospitals were better equipped with masks of variable sizes, oxygen blender, T-piece resuscitator, and electrocardiographic monitor (all Ps < 0.001). In the maternity hospitals, the preparedness of oxygen blender or T-piece resuscitator was positively associated with the number of pediatricians (P = 0.005). Although bag-mask ventilation was mostly feasible in both groups, endotracheal intubation was less feasible in the maternity hospitals (P = 0.007). The annual participation in resuscitation training for providers was higher in the KNN hospitals (P < 0.001). In the maternity hospitals, the annual participation was positively associated with the numbers of deliveries, obstetricians, and pediatricians. @*Conclusion@#This preliminary survey indicates the need for further improvement in preparing in personnel, equipment, and education, particularly in maternity hospitals.

ABSTRACT

PURPOSE: To investigate the hemodynamic risk factors for necrotizing enterocolitis (NEC), we analyzed the characteristics of descending aorta (DA) blood flow in preterm neonates, who later developed NEC. METHODS: This was an observational case-control study on 53 preterm neonates at a tertiary referral center. Clinical and echocardiographic data were collected from 23 preterm neonates with NEC (NEC group), and compared with those of 30 preterm neonates without NEC (control group). Echocardiography was done at a median (interquartile range) of 5 (3–9) days after birth and 2 (1–2.5) days before the diagnosis of NEC. RESULTS: Basic clinical characteristics including gestational age, birth weight, Apgar score, breast feeding status, use of umbilical catheters, and mode of invasive ventilator care were similar between the groups. Compared with the control group, the lowest diastolic velocity of DA was significantly decreased, whereas the diastolic reverse flow and the ratio of diastolic reverse to systolic forward flows were significantly increased in the NEC group. In addition, the resistive index (RI) of DA was significantly increased in the NEC group and showed a positive association with the development of NEC. Multivariate logistic regression analysis showed that increasing RI of DA was an independent risk factor for the development of NEC (P=0.008). CONCLUSION: Significant changes in DA flow characteristics including decreased diastolic velocity and increased diastolic reverse flow along with increased peripheral vascular resistance were observed before the development of NEC in preterm neonates. These findings may help clinicians stratify in advance neonates at a risk of developing NEC and may help improve outcomes in these neonates.

ABSTRACT

PURPOSE: The purpose of this study was to examine the usefulness of abdominal sonography in the diagnosis of necrotizing enterocolitis (NEC). METHODS: We reviewed the medical records of 51 neonates who were diagnosed with NEC in the neonatal intensive care unit at Yeouido St. Mary's Hospital of the Catholic University in Korea between January 2008 and December 2012. The neonates underwent abdominal ultrasonography on the day of their diagnosis and on the third day after diagnosis. Simple abdominal radiography was performed on the same day as the sonography. The neonates were diagnosed with NEC in accordance with the abdominal sonographic findings. Abdominal radiography and sonography were used to assess the NEC stages in the neonates. RESULTS: On the day of NEC diagnosis by abdominal sonography, 50 neonates were diagnosed with stage II NEC and 1 was diagnosed with stage III NEC. However, simple radiography diagnosed 49 neonates with stage I NEC, 1 with stage II NEC, and 1 with stage III NEC. On the third day after NEC diagnosis by abdominal sonography, 48 neonates were diagnosed with stage II NEC and 3 were diagnosed with stage III NEC. On the other hand, simple radiography diagnosed 26 neonates with stage I NEC, 24 with stage II NEC, and 1 with stage III NEC. CONCLUSION: Abdominal sonography can be used as a tool for accurately diagnosing NEC and treating neonates showing ambiguous symptoms during the early stages of NEC.

ABSTRACT

PURPOSE: The purpose of this study is to investigate the perinatal risk factors for severity of intraventricular hemorrhage (IVH) in very low birth weight infants (VLBWIs) and to study the following neurodevelopmental outcomes depending on the degree of IVH severity. METHODS: The retrospective study included 145 VLBWIs who were admitted at Seoul St. Mary's Hospital between May of 2009 and April of 2013. Prenatal, obstetric and postnatal risk factors for IVH were investigated. VLBWIs were divided into the group of IVH grade 1-2 and IVH grade 3-4. During this study period, 26 VLBWIs were died and 11 VLBWIs were lost to followed up, thereby 108 infants were included in the final analysis. They were regularly followed up and assessed for presence of major neurodevelopmental impairments including cognitive impairment, cerebral palsy, visual deficit, hearing deficit, and epilepsy. Among 108 infants, 23 (21.3%) patients had neurodevelopmental impairments. RESULTS: The lower gestational age and birth weight were significant prenatal risk factors for severe IVH. Lower Apgar score at 1 and 5 min, hypotension/shock, higher levels of partial pressure of carbon dioxide, presence of patent ductus arteriosus, pneumothorax, thrombocytopenia, necrotizing enterocolitis, and bronchopulmonary dysplasia were significant postnatal risk factors for severe IVH. After multiple logistic regression analysis, gestational age, birth weight, and hypotension/shock were independent risk factors for severe IVH. The incidence of major neurodevelopmental impairments were also significantly higher in VLBWIs who survived after severe IVH. CONCLUSION: In addition to preterm birth, minimizing hypotension/shock, the risk factor of severe IVH, is important to prevent major neurodevelopmental impairments in VLBWIs.

ABSTRACT

PURPOSE: The use of cyclosporine and mini-dose methotrexate (MTX) is a common strategy for graft-versus-host disease (GVHD) prophylaxis in allogeneic transplants. We investigated whether patients who receive fewer than the planned MTX doses are at increased risk for GVHD. METHODS: The study cohort included 103 patients who received allogeneic transplants at the Department of Pediatrics of The Catholic University of Korea College of Medicine, from January 2010 to December 2011. MTX was administered on days 1, 3, 6, and 11 after transplant at a dose of 5 mg/m2 each. Within the cohort, 76 patients (74%) received all 4 doses of MTX [MTX(4) group], while 27 patients (26%) received 0-3 doses [MTX(0-3) group]. RESULTS: Although there was no difference in neutrophil engraftment between the 2 groups, platelet engraftment was significantly faster in the MTX(4) group (median, 15 days), compared to the MTX(0-3) group (median, 25 days; P=0.034). The incidence of grades II-IV acute GVHD was not different between the MTX(4) and MTX(0-3) groups (P=0.417). In the multivariate study, human leukocyte antigen mismatch was the most significant factor causing grades II-IV acute GVHD (P=0.002), followed by female donor to male recipient transplant (P=0.034). No difference was found between the MTX(4) and MTX (0-3) groups regarding grades III-IV acute GVHD, chronic GVHD, and disease-free survival. CONCLUSION: Our results indicate that deviations from the full dose schedule of MTX for GVHD prophylaxis do not lead to increased incidence of either acute or chronic GVHD.

ABSTRACT

Streptococcus anginosus is a member of Streptococcus milleri group, and is found in the oral mucosa, respiratory tract, and gastrointestinal tract as normal flora. It can develop into a disease in patients with deteriorating clinical condition or with clinical risk factors. A previously healthy 15-year-old boy was admitted due to fever, abdominal discomfort and vomiting which lasted for 7 days. He had a history of dental procedure 1 day before the development of fever. He was diagnosed with acute acalculous cholecystitis based on the clinical, laboratory, and imaging finding, and S. anginosus was isolated from the blood culture. The patient was successfully treated with antibiotic therapy.

ABSTRACT

A recent resurgence of pertussis has raised public health concerns even in developed countries with high vaccination coverage. The aim of this study was to describe the clinical characteristics of infant pertussis, and to determine the relative importance of household transmission in Korea. The multicenter study was prospectively conducted from January 2009 to September 2011. We identified the demographic and clinical data from these patients and performed the diagnostic tests for pertussis in their household contacts. Twenty-one patients with confirmed pertussis were included in the analysis. All infections occurred in infants younger than 6 months of age (mean age, 2.5 months) who had not completed the primary DTaP vaccination except for one patient. Infants without immunization history had a significant higher lymphocytosis and longer duration of hospital stay compared to those with immunization. All were diagnosed with PCR (100%), however, culture tests showed the lowest sensitivity (42.9%). Presumed source of infection in household contacts was documented in 85.7%, mainly parents (52.6%). Pertussis had a major morbidity in young infants who were not fully immunized. Household members were responsible for pertussis transmission of infants in whom a source could be identified. The control of pertussis through booster vaccination with Tdap in family who is taking care of young infants is necessary in Korea.
