RESUMEN
Permanent junctional reciprocating tachycardia (PJRT) is a rare form of congenital arrhythmia occurring predominantly in infants and children. Prenatal presentation is frequently characterized by incessant tachycardia leading to dilated cardiomyopathy (DCM). Some patients can have a normal heart rate which leads to a delayed diagnosis. We report a case of a neonate who was presented prenatally with DCM, fetal hydrops, and no signs of fetal arrhythmia. Diagnosis of PJRT was established after delivery with characteristic electrocardiographic patterns. Successful conversion to sinus rhythm with digoxin and amiodarone was achieved three months later. At 16 months of age, both echocardiography and electrocardiography were normal.

Fetal/neonatal alloimmune thrombocytopenia (FNAIT) is a rare life-threatening disorder, leading to severe thrombocytopenia and potentially bleeding, with intracranial haemorrhage (ICH) being the most serious complication. We report on a FNAIT case with fourth-degree ICH that arose due to antibodies against human platelet antigen (HPA)-1b. The male infant, born to an otherwise healthy mother, presented with severe signs of ICH soon after delivery. Since only moderate thrombocytopenia was noted and there were no active signs of bleeding, the infant did not receive intravenous immunoglobulins (IVIg) or platelet transfusion. Spontaneous recovery of platelets was noted on the eighth day of life, but permanent neurological impairment remained as a consequence of ICH. We report the results of HPA and human leukocyte antigen (HLA) antibodies in the mother's and the infant's sera, the family's HPA genotype and the mother's HLA genotype, and summarise previously described cases of FNAIT due to anti-HPA-1b antibodies in the literature. FNAIT with severe ICH due to anti-HPA-1b antibodies is rarely diagnosed. An association between HLA genes and sensitization to HPA-1b antibodies was not demonstrated. The severity of FNAIT and the occurrence of ICH is often difficult to predict. In this case, the infant presented with moderate thrombocytopenia and ICH, with subsequent permanent consequences.

AIM: To evaluate the relationship between the neurological outcome, neonatal epileptic seizures, and signal-intensity visibility of the frontal and parietal periventricular crossroads of pathways on brain magnetic resonance imaging (MRI) in preterm infants at term-equivalent age. METHODS: The study enrolled 48 preterm infants born between 2012 and 2016. The signal-intensity characteristics of the frontal and parietal periventricular crossroads were evaluated and classified into four grades. A non-favorable outcome was defined as a motor and functional disorder with developmental delay and/or cerebral palsy. RESULTS: Neonatal seizures, epilepsy, pathological EEG and brain ultrasound finding, and brain MRI abnormalities were mostly found in neonates with non-favorable outcomes. Visible frontal and parietal periventricular crossroads were associated with a normal neurologic outcome (P=0.0004; P=0.0009, respectively). Not-visible or slightly visible periventricular crossroads were associated with non-favorable outcomes in the case of frontal crossroads (P=0.036) and not-visible periventricular crossroads in the case of both frontal and parietal crossroads (P=0.001, P=0.015, respectively). The visibility of the frontal and parietal periventricular crossroads was associated with a lack of neonatal epileptic seizures (P=0.03; P=0.02, respectively). The frontal crossroads were more frequently slightly visible, while the parietal periventricular crossroads were more frequently visible. CONCLUSION: Poor visibility of the frontal and parietal crossroads of pathways on MRI is associated with neonatal epileptic seizures and poor neurological outcomes in preterm infants at term-equivalent age.

BACKGROUND: Hyperammonemic encephalopathy in newborns with urea cycle disorders and certain organic acidurias can cause severe brain injury, coma and death. Standard therapy includes protein restriction, nitrogen-scavenging drugs, prevention of catabolism and hemodialysis. Neuroprotective hypothermia as part of the treatment has been reported only 3 times. It has been suggested that mild systemic hypothermia can contribute to better neurological outcomes in hyperammonemic encephalopathy. However, the limited experience precludes accurate conclusions on safety and efficacy. METHODS: Whole body therapeutic hypothermia was included in the standard treatment of hyperammonemic encephalopathy in 4 neonates with urea cycle disorder or organic aciduria. RESULTS: Two patients survived the initial crisis. One patient has a developmental quotient of 0.8, while the other shows severe developmental delay. The cooling protocol had to be discontinued in 3 patients due to the otherwise untreatable complications (hypotension and hemorrhage). CONCLUSION: The efficacy and safety of therapeutic hypothermia in the treatment of neonatal hyperammonemic encephalopathy depend on various factors, requiring further evaluation.

Conjoined twining is a rare medical phenomenon, with an overall prevalence of 1.47 per 100 000 births. This report describes a successful separation of xypho-omphalopagus conjoined twins complicated by unbalanced blood shunting through the porto-systemic anastomoses within the shared liver parenchyma. Significant extrauterine twin-twin transfusion syndrome caused by unbalanced shunting is an extremely rare, and probably under-recognized, hemodynamic complication in conjoined twins necessitating urgent separation. Progressive deterioration with a poor outcome can be prevented if the condition is recognized in a timely manner.

BACKGROUND: Patients with congenital diaphragmatic hernia (CDH) have a high residual morbidity rate. We compared self-reported health-related quality of life (HRQoL) between patients with CDH and healthy children. METHODS: Forty-five patients with CDH who were born from January 1, 1990, through February 15, 2015, were matched to healthy, age-matched control participants at a 1:2 ratio. The health records of the study participants were reviewed to determine comorbid conditions, and HRQoL was assessed by both the participants and their parents with the Pediatric Quality of Life Inventory (PedsQL). The HRQoL scores of the patients with CDH and the control participants were compared by using analysis of variance to adjust for age group and sex. Among patients with CDH, analysis of variance was used to compare HRQoL scores across groups defined according to their characteristics at initial hospitalization, postdischarge events, and comorbid conditions. RESULTS: Compared with control participants, patients with CDH had lower mean PedsQL scores, as reported by the parent and child, for the physical and psychosocial domains (P < 0.001). Risk factors associated with lower parent-reported HRQoL included bronchopulmonary dysplasia, longer initial hospitalization, severe cognitive impairment, and orthopedic symptoms; among patients with CDH, low HRQoL was associated with chronic respiratory issues. CONCLUSION: Patients with CDH had lower HRQoL compared with healthy participants. Parent-reported HRQoL tended to be higher than child-reported HRQoL. Results were also inconsistent for the risk factors associated with HRQoL obtained by using child- and parent-reported scores. Therefore, when interpreting HRQoL in CDH survivors, a proxy report should not be considered a substitute for a child's self-report.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a rare anomaly with high mortality and long-term comorbid conditions. AIMS: Our aim was to describe the presenting characteristics, treatment, and outcomes of consecutive patients with CDH treated at our institution. METHODS: We performed a retrospective cohort study and identified consecutive neonates treated for CDH from 2001 to 2015 at our institution. For all patients identified, we reviewed hospital and postdischarge data for neonatal, disease, and treatment characteristics. We determined hospital survival overall and also according to the presence of prenatal diagnosis, liver herniation into the chest (liver up), and the use of extracorporeal membrane oxygenation (ECMO) in addition to surgery. We evaluated postdischarge chronic conditions in patients with at least one year of follow-up. RESULTS: Thirty-eight neonates were admitted for treatment during the study period. In three who were in extremis, life support was withdrawn. The other 35 underwent surgical repair, of whom eight received ECMO. The overall survival was 79% (30/38). Survival for those who had surgical correction of CDH but did not need ECMO was 89% (24/27); it was 75% (6/8) for those who received ECMO and had surgery. Hospital survival was lower for liver-up vs liver-down CDH (61% [11/18] vs 95% [19/20]; odds ratio, 0.08; 95% CI, 0.01-0.77; P = 0.01). Among survivors, the median duration of hospitalization was 31 (interquartile range, 20-73) days. Major chronic pulmonary and gastrointestinal disorders, failure to thrive, and neurodevelopmental delays were the most noted comorbid conditions after discharge, and all were more prevalent in those who required ECMO. CONCLUSION: The overall survival of neonates with CDH was 79%. Intrathoracic liver herniation was associated with more frequent use of ECMO and greater mortality. A substantial number of survivors, especially those who required ECMO, experienced chronic conditions after discharge.

Background Congenital diaphragmatic hernia (CDH) has different clinical presentations depending on whether it is right sided (R-CDH) or left sided (L-CDH). Some have suggested that L-CDH and R-CDH may represent different syndromic phenotypes. This theory would be indirectly supported if different nondiaphragmatic anomalies were associated with laterality. We assessed whether CDH laterality is associated with specific types of nondiaphragmatic anomalies. Methods Cases of CDH were retrospectively identified from five centers, and associated congenital anomalies, prenatal diagnosis, demographics, birth characteristics, and side of the CDH were analyzed. CDH characteristics were summarized according to the absence (isolated) or presence (complex) of nondiaphragmatic malformations. Results Among 228 neonates with CDH, 140 (61%) had isolated CDH and 88 (39%) had complex CDH. Complex CDH was significantly associated with being small for gestational age (odds ratio [95% confidence interval, CI]: 8.3 [1.9-35.7]; p = 0.005) and having L-CDH (odds ratio [95% CI]: 3.6 [1.5-8.9]; p = 0.005). The overall proportion with anomalies differed by side (42% for L-CDH, 23% for R-CDH; p = 0.02), but the rates of anomalies in specific organ systems did not differ. Conclusion The rate of associated nondiaphragmatic anomalies by specific organ system did not differ between L-CDH and R-CDH, which suggests that they represent the same phenotypic entity.

Objective The objective of this study was to investigate the prognostic value of a hernia sac in isolated congenital diaphragmatic hernia (CDH) with intrathoracic liver herniation ("liver-up"). Study Design A retrospective study from the single tertiary center. Isolated "liver-up" CDH neonates referred to our institution between 2000 and 2015 were reviewed for the presence or absence of a hernia sac. Association between the presence of a hernia sac and survival was assessed. Results Over the study period, there were 29 isolated CDH patients with "liver-up" who were treated, 7 (24%) had a sac, and 22 (76%) did not. Demographics were similar between groups. However, disease acuity, assessed from lower Apgar scores (p = 0.044), lower probability of survival (p = 0.037), and lower admission oxygenation (p = 0.027), was higher in neonates without a sac. Hospital survival was significantly higher for those with sac compared with those without (7/7, 100 vs. 7/22, 32%, p = 0.002). Conclusion The presence of a hernia sac may be associated with better survival for isolated "liver-up" CDH. As the presence of sac can be prenatally detected, it may be a useful marker to aid perinatal decision making.

BACKGROUND: Outcomes of neonates with congenital diaphragmatic hernia (CDH) are variable; reports are frequently limited to the experience of single tertiary care centres-a possible source of bias. Population-based studies decrease survivor bias and provide additional insight into this high-mortality condition. The objective of this study was to examine the incidence and outcomes of CDH in Croatia. METHODS: All cases of CDH in Croatia from 2001 through 2013 were ascertained from public health records. Overall and sex- and region-specific incidence rates were calculated, and characteristics associated with 1-year survival were assessed. RESULTS: We identified 145 cases of CDH during the study period, for an incidence of 2.67 per 10 000 total births. The incidence did not differ by calendar year (P = 0.38) or geographic region (P = 0.67). There was a slightly higher incidence among males (rate ratio, 1.37, 95% CI 0.99, 1.91). The 1-year survival rate was 33.1% for the entire cohort and 47.9% for liveborns who received any treatment at an intensive care unit. From multivariable analysis, survival was decreased in neonates with left CDH, liver up (odds ratio 0.1, 95% CI, 0.03, 0.4) and increased when treated in a centre with higher case volume (odds ratio 12.8, 95% CI, 2.2, 72.1). CONCLUSIONS: The incidence of CDH in Croatia is within the range of previous reports. Survival was substantially higher in neonates treated in a centre with higher case volume, which suggests that centralisation of medical care for CDH may be warranted in Croatia.

BACKGROUND: The extent of lung hypoplasia in neonates with congenital diaphragmatic hernia (CDH) can be assessed from gas exchange. We examined the role of preductal capillary blood gases in prognosticating outcome in patients with CDH. METHODS: We retrospectively reviewed demographic data, disease characteristics, and preductal capillary blood gases on admission and within 24 h following admission for 44 high-risk outborn neonates. All neonates were intubated after delivery due to acute respiratory distress, and were emergently transferred via ground ambulance to our unit between 1/2000 and 12/2014. The main outcome measure was survival to hospital discharge and explanatory variables of interest were preductal capillary blood gases obtained on admission and during the first 24 h following admission. RESULTS: Higher ratio of preductal partial pressure of oxygen to fraction of inspired oxygen (PcO2/FIO2) on admission predicted survival (AUC = 0.69, P = 0.04). However, some neonates substantially improve PcO2/FIO2 following initiation of treatment. Among neonates who survived at least 24 h, the highest preductal PcO2/FIO2 achieved in the initial 24 h was the strongest predictor of survival (AUC = 0.87, P = 0.002). Nonsurvivors had a mean admission preductal PcCO2 higher than survivors (91 ± 31 vs. 70 ± 25 mmHg, P = 0.02), and their PcCO2 remained high during the first 24 h of treatment. CONCLUSION: The inability to achieve adequate gas exchange within 24 h of initiation of intensive care treatment is an ominous sign in high-risk outborn neonates with CDH. We suggest that improvement of oxygenation during the first 24 h, along with other relevant clinical signs, should be used when making decisions regarding treatment options in these critically ill neonates.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a congenital malformation associated with life-threatening pulmonary dysfunction and high neonatal mortality. Outcomes are improved with protective ventilation, less severe pulmonary pathology, and the proximity of the treating center to the site of delivery. The major CDH treatment center in Croatia lacks a maternity ward, thus all CDH patients are transferred from local Zagreb hospitals or remote areas (outborns). In 2000 this center adopted protective ventilation for CDH management. In the present study we assess the roles of protective ventilation, transport distance, and severity of pulmonary pathology on survival of neonates with CDH. METHODS: The study was divided into Epoch I, (1990-1999, traditional ventilation to achieve normocapnia), and Epoch II, (2000-2014, protective ventilation with permissive hypercapnia). Patients were categorized by transfer distance (local hospital or remote locations) and by acuity of respiratory distress after delivery (early presentation-occurring at birth, or late presentation, ≥ 6 h after delivery). Survival between epochs, types of transfers, and acuity of presentation were assessed. An additional analysis was assessed for the potential association between survival and end-capillary blood CO2 (PcCO2), an indirect measure of pulmonary pathology. RESULTS: There were 83 neonates, 26 in Epoch I, and 57 in Epoch II. In Epoch I 11 patients (42%) survived, and in Epoch II 38 (67%) (P = 0.039). Survival with early presentation (N = 63) was 48 % and with late presentation 95% (P <0.001). Among early presentation, survival was higher in Epoch II vs. Epoch I (57% vs. 26%, P = 0.031). From multiple logistic regression analysis restricted to neonates with early presentation and adjusting for severity of disease, survival was improved in Epoch II (OR 4.8, 95%CI 1.3-18.0, P = 0.019). Survival was unrelated to distance of transfer but improved with lower partial pressure of PcCO2 on admission (OR 1.16, 95%CI 1.01-1.33 per 5 mmHg decrease, P = 0.031). CONCLUSIONS: The introduction of protective ventilation was associated with improved survival in neonates with early presentation. Survival did not differ between local and remote transfers, but primarily depended on severity of pulmonary pathology as inferred from admission capillary PcCO2.

OBJECTIVE: Proper position of umbilical venous catheter (UVC) is of importance to avoid severe complications. We review clinical presentations of neonates with UVC who developed catheter-associated liver injury. STUDY DESIGN: We reviewed institutional intensive care database (2008-2013) and identified neonates with UVCs who developed severe hepatic injury. We recorded admission diagnosis, gestational age, birth weight, number of days the umbilical catheter was in place, its radiological position at insertion and at the time of injury, presenting clinical signs, and outcomes. RESULTS: Of 1,081 neonates, 9 (0.8% [95% exact binomial confidence interval, 0.4-1.6%]) with UVC developed severe hepatic injury. All had the UVC malpositioned within the liver circulation. All presentations were life threatening, with acute abdominal distension (hepatomegaly) being the most consistent sign. Two neonates died from complications which were unrelated to catheter-associated liver injury. CONCLUSIONS: In all neonates with liver injury, UVC was malpositioned within the portal circulation. Despite the fact that our report provides only circumstantial evidence for the mechanism of injury, it supports reports which suggest that "low" UVC position increases potential for this type of complication. Acute onset of abdominal distension in a neonate with UVC should prompt ultrasonographic evaluation of position of the catheter tip.

Objective: To examine whether variation of regional cerebral oxygen saturation (rScO2) within three days after delivery predicts development of brain injury (intraventricular/cerebellar hemorrhage or white matter injury) in preterm infants. Study design: A prospective study of neonates <32 weeks gestational age with normal cranial ultrasound admitted between 2018 and 2022. All received rScO2 monitoring with near-infrared spectroscopy at admission up to 72â h of life. To assess brain injury a magnetic resonance imaging was performed at term-equivalent age. We assessed the association between rScO2 variability (short-term average real variability, rScO2ARV, and standard deviation, rScO2SD), mean rScO2 (rScO2MEAN), and percentage of time rScO2 spent below 60% (rScO2TIME<60%) during the first 72â h of life and brain injury. Results: The median [IQR] time from birth to brain imaging was 68 [59-79] days. Of 81 neonates, 49 had some form of brain injury. Compared to neonates without injury, in those with injury rScO2ARV was higher during the first 24â h (P = 0.026); rScO2SD was higher at 24 and 72â h (P = 0.029 and P = 0.030, respectively), rScO2MEAN was lower at 48â h (P = 0.042), and rScO2TIME<60% was longer at 24, 48, and 72â h (P = 0.050, P = 0.041, and P = 0.009, respectively). Similar results were observed in multivariable logistic regression. Although not all results were statistically significant, increased rScO2 variability (rScO2ARV and rScO2SD) and lower mean values of rScO2 were associated with increased likelihood of brain injury. Conclusions: In preterm infants increased aberration of rScO2 in early postdelivery period was associated with an increased likelihood of brain injury diagnosis at term-equivalent age.
RESUMEN
UNLABELLED: The presence of ductal plate malformation (DPM+) on liver histology in children with biliary atresia (BA) is a marker of early intrauterine disease onset and an indication of an unfavorable prognosis. We studied the prognostic value of DPM in infants with BA after hepatoportoenterostomy (HPE). We reviewed 28 BA patients who underwent HPE in a single medical center. We examined the time of jaundice onset after delivery (conjugated hyperbilirubinemia): early onset (fetal phenotype with no jaundice-free interval) vs. late onset (perinatal phenotype with jaundice-free interval) and the presence or absence of DPM (DPM+ or DPM-) histopathology. Primary outcome was jaundice clearance at 3 months after HPE and survival with native liver (SNL). Eight children had fetal and 20 had perinatal BA (8 DPM+, 12 DPM-). At 3 months after HPE, no patients with fetal BA had achieved jaundice clearance, while jaundice clearance was achieved in five patients with DPM+ perinatal disease and four patients with DPM- perinatal BA (P = 0.03, comparing all three groups; P = 0.36, comparing DPM+ vs. DPM- perinatal patients). Median SNL was 8.6 months for fetal BA patients, 148.2 months for DPM+ perinatal BA patients, and 93.2 months for DPM- perinatal BA patients (log-rank test, P < 0.001, comparing all three groups; P = 0.59, comparing DPM+ vs. DPM- perinatal patients). After adjusting for BA type, age older than 2 months at HPE was associated with worse SNL [P = 0.03; hazard ratio = 4.0 (95 % CI, 1.1-14.2)]. CONCLUSIONS: Early onset of jaundice, regardless of DPM histology, was the most ominous sign of poor outcome in infants with BA after HPE.

AIM: To explore the relationships between transient structural brain patterns on MRI at preterm and at term-equivalent age (TEA) as a predictor of general movements (GMs) and motor development at 1-year corrected age (CA) in very preterm infants. METHODS: In this prospective study, 30 very preterm infants (median = 28wks; 16 males) had structural magnetic resonance imaging (MRI) at preterm (median = 31wks + 6d) and at TEA (median = 40wks) and neuromotor assessments. The quality of GMs was assessed by Prechtl's general movements assessment and a detailed analysis of the motor repertoire was performed by calculating a motor optimality score (MOS), both at term age and at 3 months post-term. Motor development at 1-year CA was evaluated with the Infant Motor Profile (IMP). Associations between qualitative MRI findings and neuromotor scores were investigated. RESULTS: Abnormal GMs and low motor performance at 1-year CA were associated with the poor visibility of transient structural pattern, that is with sagittal strata. INTERPRETATION: Transient structural MRI pattern, sagittal strata, at preterm age is related to the quality of GMs and later motor development in preterm infants. This transient fetal brain compartment may be considered as a component of neurobiological basis for early neuromotor behavior, as expressed by GMs.

The objective of this study was to determine the outcomes of Croatian children with biliary atresia. Health records of infants born in Croatia between January 1, 1992 and December 31, 2006 who were diagnosed with biliary atresia and treated at a single university center were reviewed. Survival rates were calculated with the Kaplan-Meier method. Twenty-nine patients with biliary atresia were identified. Incidence was one in 23,600 live births (95% confidence interval 1/17,400-1/27,200). The median age at Kasai operation was 66 days (range 22-192). Median follow-up was 2.65 years (range 0.2-14.3). Overall survival rates for the patients who underwent Kasai portoenterostomy, including those six (20%) who subsequently underwent liver transplantation, were 75.6%. Five and 10-year native liver survival rates were 51.7% and 38.8%, respectively (median survival time was 7.88 years). Survival rate curves in two groups of patients according to the biliary atresia phenotype (fetal or perinatal form) were divergent. Survival was 87.7% in perinatal form and 43.8% in fetal form (Breslow chi-square 8.082, p < 0.01). Overall survival rates of patients with biliary atresia in Croatia compared unfavorably with current international standards; this could be improved with earlier referral for liver transplantation. Results of Kasai operation (native liver survival rates) compared favorably with results reported elsewhere.

OBJECTIVE: The rate of congenital diaphragmatic hernia (CDH) varies, but most reports estimate the incidence to be less than three per 10,000 births. Our objective was to document the incidence of CDH in a geographically well-defined population using available resources for highly accurate incident case ascertainment. METHODS: We ascertained CDH cases in Olmsted County, Minnesota, United States of America, from 1981 through 2014 using resources of the Rochester Epidemiology Project. Overall and sex-specific incidence rates were calculated, and hospital survival was assessed. RESULTS: A total of 26 incident CDH cases were identified; the overall incidence of 3.6 (95% CI, 2.2-5.0) per 10,000 did not differ significantly over the 34-year study period (p = .28). The estimated incidence was 4.3 (95% CI, 2.2-6.5) for male infants and 2.9 (95% CI, 1.1-4.6) for female infants. The percentage of cases diagnosed prenatally was 33% from 1981 through 2000 and 50% from 2001 through 2014. The rate of survival to discharge in the two periods was 50% and 88%. CONCLUSION: The incidence of CDH in Olmsted County exceeds the majority of published rates, which most likely can be attributed to our comprehensive case ascertainment.
