RESUMEN

Introduction: Purpura fulminans in the neonatal population is a rare but potentially life-threatening condition complicated by thrombosis, resultant vital organ necrosis, and gangrene of the extremities. Considering the rapid evolution of the pathogenetic mechanism, an index of suspicion, early identification, and prompt intervention are imperative for improved outcomes. The majority of purpura fulminans cases have an infectious etiology, but it is essential to consider other congenital and acquired causes. Case description: We present a clinical case of a female neonate to emphasize the correlation between purpura fulminans, congenital chylothorax, involvement of the PAK2 gene, and the occurrence of retinal detachment in both eyes. After draining the congenital chylothorax, the neonate developed purpura fulminans due to a loss of protein C, S, and antithrombin factors, previously not reported in the literature. The purpuric lesions resolved after the administration of fresh frozen plasma. Subsequently, no recurring purpura fulminans lesions were noted following the normalization of the antithrombotic factor levels in the serum. Subsequently, the child also developed retinal detachment in both eyes.

RESUMEN

Introduction: Extremely premature infants are susceptible to fluctuations in cerebral blood flow due to immaturity of cerebral autoregulation. Inotropes may cause rapid changes to systemic blood pressure and consequently cerebral blood flow, especially within the first 72 hours of life. This period is recognized to carry the greatest risk for cerebral hemorrhage. This study evaluates the incidence of death and/or severe brain injury in extremely preterm infants treated with inotropes in the first 72 hours of life.Methods: Prospective cohort study of infants born ≤29+0 weeks gestational age (GA) between January 2013 and December 2016. Severe brain injury was defined based on head ultrasound as presence of: grade III or IV intraventricular hemorrhage (IVH), moderate to severe post-hemorrhagic ventricular dilatation (PHVD), or cystic periventricular leukomalacia (cPVL). The association between inotrope use and death and/or brain injury was explored via logistic regression controlling for predefined confounding risk factors.Results: Of 497 eligible infants, 97 (19.5%) received inotropes during the first 72 hours. GA at birth, birth weight (BW), and 5-minute Apgar scores were lower among infants who received early inotropes compared to those not treated with inotropes. A stepwise logistic regression of the predefined confounding factors showed GA, exposure for antenatal steroids, and admission hypothermia to be significant confounding factors. Adjusting for those factors, early use of inotropes was associated with increased risk of death and/or severe brain injury (AOR 4.5; 95%CI: 2.4-8.5), severe brain injury (AOR 4.2; 95% CI: 1.9-8.9), and IVH of any grade (AOR 2.9; 95%CI: 1.7-4.9).Conclusion: Early inotropes use was associated with higher risk of death and/or severe brain injury. Strict indications and strategies for minimizing inotrope use while preventing hypotension should be implemented in the early postnatal care of infants at risk for severe brain injury.

RESUMEN

OBJECTIVE: To determine if umbilical venous catheter (UVC) insertion depth estimated by surface measurement (SM) results in optimal catheter tip position on ultrasound as compared with formula using birth weight (BW). METHODS: In this randomized controlled trial, eligible infants were randomized to UVC insertion depth estimated by SM or BW method. We compared proportion of optimum UVC position on ultrasound read by neonatologist masked with group assignment. RESULTS: UVC was inserted to estimated depth in 164 of 200 enroled infants. There was no difference in the proportion of correctly positioned UVCs between the groups (SM 33/82 (40.2%) vs BW 27/82 (32.9%), p = 0.33). Among BW < 1000 g, SM method had higher correctly positioned UVC (43.7% vs 22.5%, p = 0.07). CONCLUSION: There was no difference in the rate of optimally positioned UVC tip between the two methods for estimating UVC insertion depth. However, SM method results in more optimal positioning of UVC tip among BW < 1000 g infants.

RESUMEN

OBJECTIVES: Brain injury in preterm neonates may cause clinical deterioration and requires timeous bedside diagnosis. Teaching cranial ultrasound (US) skills using fragile preterm neonates is challenging. The purpose of this study was to test the effectiveness and feasibility of using task-trainer computer-based simulators and US-suitable cranial phantoms in combination with teaching sessions in teaching novices to perform focused cranial US evaluations for identifying substantial intraventricular hemorrhage. METHODS: This was a prospective interventional educational study targeting participants with no prior skills in neonatal cranial US. Participants attended a 2-day training workshop, with didactic and hands-on interactive sessions using computer-based and 3-dimensional printed phantom simulators. Participants then performed a cranial US scan on a healthy neonate to assess the diagnostic quality of the images acquired. Individual precourse and postcourse knowledge tests were compared. To test recall, participants also submitted US images acquired on neonates within 3 and 6 months of attending the course. RESULTS: Forty-five participants completed the training modules. Mean knowledge scores increased significantly (in brain anatomy, brain physiology, intracranial disorders, and US physics domains). Thirty-eight cranial US scans were acquired during the course, 22 within 3 months after completion, and 34 within 6 months after completion. Thirty-two (84%) of the initial 38 case images, 17 (77%) of 22 images submitted within 3 months, and 32 (94%) of 34 images submitted within 6 months after course completion were of diagnostic quality. CONCLUSIONS: A structured training module with didactic and hand-on training sessions using simulators and phantoms is feasible and supports training of clinicians to perform focused cranial US examinations.

RESUMEN

Objectives: To assess maternal and neonatal risk factors for intraventricular hemorrhage (IVH). To examine the association of patent ductus arteriosus (PDA) and its treatment, with IVH and its severity. Study design: In this retrospective cohort study, we included preterm neonates born at <29 weeks, admitted to a tertiary level III Neonatal Intensive Care Unit in Calgary, Canada, between 2013 and 2016, who had a head ultrasound in the first 7 days of life. A subset analysis included neonates who also had cardiac ultrasound in the first 3 days of life. Results: Of the 495 neonates, 121 (24.4%) had IVH of any grade and 48 (9.7%) had severe IVH. Identified risk factors were small birth gestation and weight, lack of antenatal corticosteroids, maternal chorioamnionitis, Apgar score <5 at 5 min, umbilical cord pH < 7, respiratory distress syndrome, early onset sepsis, hypercapnia, pCO2 fluctuations, prolonged intubation, inhaled nitric oxide, inotropes or normal saline boluses, metabolic derangements, opioids infusions, and bicarbonate/THAM therapy. In a primary analysis of the total cohort, when the decision to treat a PDA was used as a surrogate marker of its clinical significance, a PDA requiring treatment was associated with a higher risk of IVH. There was no significant difference in the incidence of IVH between neonates with early treatment of a clinically significant PDA compared to late, however early indomethacin treatment was associated with reduced severity of IVH. In the subset analysis, the presence of a hemodynamically significant PDA (hs-PDA) was not associated with a higher probability of IVH. Of those with severe IVH, 18 (55%) had a hs-PDA; this is clinically but not statistically significant. Conclusions: Identified risk factors should be the target of IVH reduction bundles. Early indomethacin treatment for a clinically significant PDA may reduce IVH severity.

RESUMEN

BACKGROUND: Limited point-of-care ultrasound skills for ultrasound-naïve neonatal transport clinicians could enhance clinical evaluation and decision making. Teaching Respiratory Therapists and Nurses to assess cardiac filling and contractility may be feasible. METHODS: Prospective educational study using educational materials, didactic theoretical, and hands-on practical sessions, followed by assessment of practical and theoretical skills. RESULTS: A total of 18 participants completed the study meeting the predefined standard, proving feasibility. Nine (50%) participants had ≤ 10 years of NICU experience. The mean time required for complete training was 8.6 ±â€¯2.1 hours. Time was spent on average on 269 ±â€¯104 minutes for hands-on practice, 171 ±â€¯96 minutes on didactic training, and 76 ±â€¯16 minutes on testing sessions. The median number of hands-on sessions per participant was 5 [Interquartile range (IQR) 5, 7]. The median number of infants required to complete training was 9 infants (IQR 7, 11). RRTs required less time than RNs. Evaluations and feedback from participants on the training program was positive. CONCLUSION: Neonatal RNs and RTs can be trained to perform focused cardiac ultrasound examinations with average time of 8.6 hours. This skill could enhance clinical care on neonatal transport with appropriate interventions to manage suspected hypotension or shock.

RESUMEN

OBJECTIVE: To evaluate the prevalence, risk factors, and optimal timing of echocardiogram for pulmonary hypertension (PH) in infants with bronchopulmonary dysplasia (BPD). DESIGN: In this prospective study, infants with gestational age (GA) <30 weeks admitted to a tertiary NICU between July 2015 and June 2017 who required positive pressure ventilation or oxygen therapy at ≥28 days of life were evaluated with serial echocardiograms at study enrollment (4-6 weeks of age), 32 weeks (only for ≤25 weeks), 36, and 40 weeks post-menstrual age (PMA) for PH. RESULTS: Of 126 infants (mean birth weight 858 ± 221 g; mean GA 26.1 ± 1.6 wks), 48 (38%) developed PH at any time during their hospital stay. The first study echocardiogram was performed at a median age of 31 weeks PMA. The prevalence of PH was 36/126 (28.5%) at enrollment, at 6/30 (20%) at 32 weeks, 24/111 (21.6%) at 36 weeks, and 10/59 (17%) at 40 weeks. No new cases of PH were identified at 40 weeks. At 36 weeks, none of the infants with mild BPD had PH, whereas 20% of moderate and 32% of severe BPD infants had PH. After controlling for confounding variables severe BPD (OR 3.31, 95%CI 1.12, 9.74), and ventilator associated pneumonia (VAP) (OR 17.9, 95%CI 3.9, 82.11) remained independent risk factors for BPD-associated PH. CONCLUSION: Echocardiographic screening for PH can be safely restricted to infants with moderate or severe BPD at 36 weeks PMA. We identified VAP as an independent risk factor for PH.

RESUMEN

In utero sensory stimuli and interaction with the environment strongly influence early phases of fetal and infant development. Extremely premature infants are subjected to noxious procedures and routine monitoring, in addition to exposure to excessive light and noise, which disturb the natural sleep cycle and induce stress. Non-invasive ventilation, measures to prevent sepsis, and human milk feeding improve short-term and long-term neurodevelopmental outcomes in premature infants. To preserve brain function, and to improve quality of life and long-term neurodevelopmental outcomes, the focus now is on the neonatal intensive care unit (NICU) environment and its impact on the infant during hospital stay. The objectives of this write-up are to understand the effects of environmental factors, including lighting and noise in the NICU, on sensory development of the infant, the need to decrease parental and caregiver stress, and to review existing literature, local policies and recommendations.

RESUMEN

OBJECTIVE: To compare long-term neurodevelopmental and growth (NDG) outcomes at 3 y corrected gestational age (GA) in premature infants with grade ≥ III intraventricular hemorrhage (IVH) and post-hemorrhagic hydrocephalus who were treated with ventriculo-peritoneal shunt with those who were not treated with shunt. METHODS: In a retrospective cohort study, NDG outcomes were compared between preterm infants of <29 wk GA with IVH treated with shunt (IVHS) and IVH with no shunt (IVHNS). This was a single centre study. The primary outcome was moderate to severe cerebral palsy (CP). RESULTS: Of 1762 preterm infants who survived to discharge, 90 had grade ≥ III IVH. Infants in IVHS group had more grade IV IVH than IVHNS (p < 0.05). Seventy percent of the patients in IVHNS groups had no hydrocephalus. IVHS group had increased CP (76% vs. 30%; p 0.003), and higher odds of CP after controlling for GA and IVH grade [odds ratio (OR); 4.23 (1.38 to 13.00)]. Growth delay was not different between groups. CONCLUSIONS: Infants with IVHS are at increased risk of CP but not growth delay.

RESUMEN

Despite the near universal adaptation of gentle mechanical ventilation, surfactant use and non-invasive respiratory support, bronchopulmonary dysplasia (BPD) remains one of the most common respiratory morbidities in very low birth weight (VLBW) infants. Thus, the objective of this review was to evaluate the efficacy of intra-tracheal administration of budesonide-surfactant mixture in preventing bronchopulmonary dysplasia (BPD) in very low birth weight (VLBW) infants. MEDLINE, EMBASE, and PubMed were searched for randomized clinical trials in which intra-tracheal administration of budesonide-surfactant was used to prevent BPD in infants. The primary outcomes were BPD and composite outcome of death or BPD. Meta-analysis of the two clinical trials revealed that infants who received intra-tracheal instillation of budesonide-surfactant mixture demonstrated 43% reduction in the risk of BPD (RR: 0.57; 95%CI: 0.43-0.76, NNT = 5). Although mortality was not different between the groups (OR: 0.61; 95%CI: 0.34-1.04), a 40% reduction was observed in the composite outcome of death or BPD in the budesonide-surfactant group (RR: 0.60; 95%CI: 0.49-0.74, NNT = 3). Thus, this review concludes that intra-tracheal administration of budesonide-surfactant combination was associated with decreased incidence of BPD alone or composite outcome of death or BPD in VLBW infants though there is a need for larger trials before it can be recommended as a standard of care.

RESUMEN

Objective To compare the new intraventricular hemorrhage (IVH) Abdi score to the Papile grading system of IVH for prediction of composite outcome of death or neurodevelopmental impairment (NDI). Methods In a cohort study, all preterm infants with IVH who were born ≤1,250 g and/or ≤ 28 weeks of gestation at birth were prospectively followed up in our neonatal follow-up clinic. All cranial ultrasounds of the included infants were reviewed by neuroradiologists who were blinded to the clinical data and neurodevelopmental outcomes. Cranial ultrasounds were graded according to the Papile scoring system and by calculation of the Abdi score. Results A total of 183 preterm infants met inclusion and exclusion criteria. Of these, 80 (44%) had the composite primary outcome of death or NDI (51 died, 29 survived with NDI). The area under receiver operating characteristic curve for predicting death or NDI was 0.87 (95% confidence interval [CI]: 0.81-0.93) for Abdi score and 0.85 (95% CI: 0.79-0.91) for Papile grading (p = 0.04). Abdi scores had higher specificity than Papile grade II at Abdi score 5 (63.9 vs. 39.2%; p < 0.001) and Abdi score 6 (73.2 vs. 39.2%; p < 0.001). Conclusion Abdi scores seem to be more specific than Papile grading system in predicting death or NDI by 3 years' corrected age.

RESUMEN

Background Cytomegalovirus (CMV) is one of the most common causes of serious viral intrauterine infections. It is universally distributed among the human population with an average incidence of 0.15 to 2%. Indeed, at least half of the women in the reproductive age have evidence of prior CMV infection. Epidemiology and Pathogenicity However, it is not a usual practice to screen asymptomatic pregnant woman or neonates for CMV. Even if a mother developed a primary CMV infection during pregnancy, up to 90% of the newborns with congenital CMV will be asymptomatic at the time of birth. Only 5 to 7% of the infected babies will be acutely symptomatic, and the typical clinical presentation includes intrauterine growth restriction, microcephaly, various cutaneous manifestations (including petechiae and purpura), hematological abnormalities (particularly resistant thrombocytopenia), hepatosplenomegaly, chorioretinitis, hepatitis, etc. In contrast, acquired CMV infection is extremely unlikely to cause any serious sequelae for the infant. Cases We present a case of congenital and acquired CMV infection in twins with a focus of dissimilarity in presentation, clinical course, and outcome.

RESUMEN

BACKGROUND: Little evidence exists regarding the optimal concentration of oxygen to use in the treatment of term neonates with spontaneous pneumothorax (SP). The practice of using high oxygen concentrations to promote "nitrogen washout" still exists at many centers. The aim of this study was to identify the time to clinical resolution of SP in term neonates treated with high oxygen concentrations (HO: FiO2 ≥ 60%), moderate oxygen concentrations (MO: FiO2 < 60%) or room air (RA: FiO2 = 21%). METHODS: A population based cohort study that included all term neonates with radiologically confirmed spontaneous pneumothorax admitted to all neonatal intensive care units in Calgary, Alberta, Canada, within 72 hours of birth between 2006 and 2010. Newborns with congenital and chromosomal anomalies, meconium aspiration, respiratory distress syndrome, and transient tachypnea of newborn, pneumonia, tension pneumothorax requiring thoracocentesis or chest tube drainage or mechanical ventilation before the diagnosis of pneumothorax were excluded. The primary outcome was time to clinical resolution (hours) of SP. A Cox proportional hazards model was developed to assess differences in time to resolution of SP between treatment groups. RESULTS: Neonates were classified into three groups based on the treatment received: HO (n = 27), MO (n = 35) and RA (n = 30). There was no significant difference in time to resolution of SP between the three groups, median (range 25th-75th percentile) for HO = 12 hr (8-27), MO = 12 hr (5-24) and RA = 11 hr (4-24) (p = 0.50). A significant difference in time to resolution of SP was also not observed after adjusting for inhaled oxygen concentration [MO (a HR = 1.13, 95% CI 0.54-2.37); RA (a HR = 1.19, 95% CI 0.69-2.05)], gender (a HR = 0.87, 95% CI 0.53-1.43) and ACoRN respiratory score (a HR = 0.7, 95% CI 0.41-1.34). CONCLUSIONS: Supplemental oxygen use or nitrogen washout was not associated with faster resolution of SP. Infants treated with room air remained stable and did not require supplemental oxygen at any point of their admission.

RESUMEN

BACKGROUND: Measures employed in preventing ventilator-associated pneumonia (VAP) in developing countries are rarely reported. This study evaluates the efficacy of an infection control program in reducing VAP in a neonatal intensive care unit (NICU) in China. METHODS: All neonates who received mechanical ventilation for at least 48 hours and were hospitalized in the NICU for ≥5 days during 3 epochs were included. The hospital relocated to a new site during phase 2 and a bundle of comprehensive preventive measures against VAP were gradually implemented using the evidence-based practice for improving quality method. Research physicians recorded associated information of patients diagnosed with VAP. RESULTS: Of 491 patients receiving mechanical ventilation, 92 (18.7%) developed VAP corresponding to 27.33 per 1,000 ventilator-days. The rate decreased from 48.84 per 1,000 ventilator-days in phase 1 to 25.73 per 1,000 ventilator-days in phase 2 and further diminished to 18.50 per 1,000 ventilator-days in phase 3 (P < .001). Overall mortality rate of admitted neonates significantly decreased from 14.0% in phase 1 to 2.9% in phase 2 and 2.7% in phase 3 (P = .000). Gram-negative bacteria (95.5%) were the predominant organisms in VAP and Acinetobacter baumannii (65.2%) was the most frequently isolated microorganism. CONCLUSIONS: Implementing a multifaceted infection control program resulted in a significant reduction in VAP rate with long-term effects. Such interventions could be extended to other low-income countries.

RESUMEN

BACKGROUND: Idiopathic infantile arterial calcification (IIAC) is a rare autosomal recessive disorder, characterized by wide spread calcifications in arterial walls, leading to vaso-occlusive ischaemia of multiple organs. Mortality is high, and there is no definitive treatment. CASE PRESENTATION: A male neonate, 36+5 weeks gestation, 2.81 kg, was admitted to NICU for respiratory distress. At one hour of age, he was noted to be pale, hypoperfused, with weak pulses, a hyperdynamic precordium and a grade IV/VI pansystolic murmur. The rest of his examination was normal. A chest X-ray showed massive cardiomegaly and pulmonary oedema. An echocardiogram (ECHO) indicated moderate persistent pulmonary hypertension (PPHN) of unclear etiology. A diagnosis of Idiopathic infantile arterial calcification was made and a trial of Editronate therapy was given without success. CONCLUSION: IIAC is a rare disorder, it should be considered whenever a neonate presents with unexplainable cardiac failure, PPHN, echogenic vessels on X-ray/ultrasound and, or concentric hypertrophic ventricles on ECHO. Serial antenatal ultrasound findings of echogenic cardiac foci should raise the suspicion of IIAC. Further studies to determine the long term effects of Editronate on vascular calcifications, disease outcome, and other treatment options are needed.

RESUMEN

OBJECTIVE: To compare the incidence of medical closure of patent ductus arteriosus (PDA) and adverse events (acute renal dysfunction, necrotizing enterocolitis, spontaneous intestinal perforation, and gastrointestinal bleeding) between preterm infants who received indomethacin and ibuprofen for the treatment of PDA. STUDY DESIGN: A retrospective comparative effectiveness evaluation study was conducted on preterm infants (≤32 weeks) who received indomethacin or ibuprofen for treatment of symptomatic PDA. RESULTS: Of the 124 eligible infants, 54 received indomethacin and 70 received ibuprofen. The overall incidence of medical PDA closure with indomethacin was 37/54 (68.5%) as compared with 42/70 (60%) in the ibuprofen group (p = 0.32). The proportion of infants with surgical PDA ligation was similar between the two groups (18.5% in both the groups). There was no difference in the incidences of acute renal dysfunction, necrotizing enterocolitis stage ≥ 2, spontaneous intestinal perforation, and gastrointestinal bleeding between indomethacin and ibuprofen groups. CONCLUSION: Ibuprofen is as effective as indomethacin in the treatment of symptomatic PDA in preterm infants. This study also shows that both agents have similar adverse effects and the choice of one agent over the other should be based on local availability and dosing preference.

RESUMEN

OBJECTIVE: Pre-eclampsia (PE) and intrauterine growth restriction (IUGR) are associated with abnormal placentation. Heme oxygenase (HO) and carbon monoxide (CO) are involved in normal placental development and function and vasomotor control in the placenta. The objective of our study was to measure CO levels, as assessed by carboxyhemoglobin (COHb) levels in the umbilical cord arterial blood of women with PE, normotensive IUGR (<10th percentile for birth weight), and normotensive pregnancies with appropriate-for-gestational age (AGA) infants. DESIGN AND METHODS: We prospectively analyzed COHb levels in the umbilical arterial blood of women with PE, normotensive IUGR, and normotensive AGA pregnancies. Exclusion criteria included cigarette smoke exposure, hemolytic disorders, a positive direct anti-globulin test, chronic hypertension, fever, and any significant medical illness. COHb levels were measured using the ABL 725 blood gas analyzer. RESULTS: There were 41 women in the normotensive AGA group, 42 in the PE group, and 36 in the normotensive IUGR group. Maternal age, mode of delivery, gravidity, parity, and gender of the infants were similar in the three groups. Gestational age and birth weight were significantly higher in the normotensive AGA group compared with the other two groups. COHb levels were significantly lower in the PE group compared with the normotensive AGA group (0.38±0.06% vs. 0.77±0.11%, P<0.05). COHb levels, although lower in the normotensive IUGR group compared with the normotensive AGA group, did not reach statistical significance. CONCLUSION: Our data suggests the HO-CO system may have a role in the pathogenesis of PE. We also, for the first time, provide information on umbilical arterial COHb levels in normotensive IUGR pregnancies.

RESUMEN

Subcutaneous fat necrosis of the newborn (SCFN) is a benign self-limited disorder commonly associated with hypothermia and perinatal asphyxia. SCFN secondary to therapeutic whole body hypothermia has rarely been reported. With increasing use of cooling for moderate to severe hypoxic ischemic encephalopathy (HIE), clinicians should recognize this potential complication.

RESUMEN

Calcium is essential for normal fetal growth and development. During intrauterine life, the fetus is entirely dependent on the mother and a normally functioning placenta for calcium accretion. Preeclampsia is associated with abnormal calcium metabolism and placental dysfunction. The objective of our study was to investigate ionized calcium levels in the umbilical cord arterial blood of women with preeclampsia and normotensive pregnancies. There were 24 women in the preeclampsia group and 25 in the normotensive group. There was no difference in the cord pH and fetal growth restriction between the two groups. Ionized calcium levels were significantly lower in the preeclampsia group (p < 0.001). Our results emphasize the need for further studies on the calcium status of infants born to mothers with preeclampsia.
