RESUMEN

Background: Cholestatic disorders are a significant cause of morbidity and mortality in infants. Characterization of these disorders and differentiating biliary atresia (BA) from other causes of intrahepatic cholestasis is an age-old problem. Objectives: To study the spectrum of different infantile cholestatic disorders in our population, to differentiate BA from other causes of neonatal cholestasis (NC) on a liver biopsy, and validation of the available scoring system for the characterization of these disorders. Materials and Methods: This is an observational cross-sectional study performed over a period of 3 years between 2018 and 2021, done on neonates and infants presenting with cholestatic jaundice. The changes on liver biopsy were evaluated by different histological parameters and available scoring systems to differentiate BA from non-BA causes. Correlation with clinical, biochemical, and imaging findings was done in all cases. Results: This study included 87 cases of NC, of which BA comprised 28 cases (32%), whereas idiopathic neonatal hepatitis (INH) comprised only 12 cases (14%). Portal neutrophilic inflammation (P = 0.000053), ductal cholestasis (P < 0.001), neoductular bile plugs (P < 0.001) and bile ductular proliferation (P < 0.0001) were significantly more in BA, whereas lobular lymphocytic inflammation (P = 0.001) and giant cell transformation of hepatocytes (P = 0.0024) were more frequent in the non-BA group. Using the Lee and Looi scoring system, a histologic score ≥7 was helpful in identifying BA with 85.7% sensitivity, 92.6% specificity, and 90.6% accuracy. Conclusion: BA is the commonest cause of NC in neonates, whereas the frequency of INH is declining. Detailed histomorphologic analysis of liver biopsy, aided with IHC, is the cornerstone for the diagnosis of these disorders.

RESUMEN

Exchange of antimicrobial resistance genes via mobile genetic elements occur in the gut which can be transferred from mother to neonate during birth. This study is the first to analyse transmissible colistin resistance gene, mcr, in pregnant mothers and neonates. Samples were collected from pregnant mothers (rectal) and septicaemic neonates (rectal and blood) and analysed for the presence of mcr, its transmissibility, genome diversity, and exchange of mcr between isolates within an individual and across different individuals (not necessarily mother-baby pairs). mcr-1.1 was detected in rectal samples of pregnant mothers (n = 10, 0.9%), but not in neonates. All mcr-positive mothers gave birth to healthy neonates from whom rectal specimen were not collected. Hence, the transmission of mcr between these mother-neonate pairs could not be studied. mcr-1.1 was noted only in Escherichia coli (phylogroup A & B1), and carried few resistance and virulence genes. Isolates belonged to diverse sequence types (n = 11) with two novel STs (ST12452, ST12455). mcr-1.1 was borne on conjugative IncHI2 bracketed between ISApl1 on Tn6630, and the plasmids exhibited similarities in sequences across the study isolates. Phylogenetic comparison showed that study isolates were related to mcr-positive isolates of animal origin from Southeast Asian countries. Spread of mcr-1.1 within this study occurred either via similar mcr-positive clones or similar mcr-bearing plasmids in mothers. Though this study could not build evidence for mother-baby transmission but the presence of such genes in the maternal specimen may enhance the chances of transmission to neonates.

RESUMEN

INTRODUCTION: Continuous positive airway pressure (CPAP) is a standard respiratory care for neonates for last few decades but it too has a high failure rate. Nasal intermittent positive pressure ventilation (NIPPV) is proven to be superior to CPAP in maintaining higher mean airway pressure in neonates with Respiratory Distress Syndrome. The main objective of this study was to compare failure within 72 h of initiation of primary respiratory support between nonsynchronized NIPPV and CPAP in all causes of respiratory distress in newborn infants. Secondarily feed intolerance, Necrotizing enterocolitis (NEC > stage II), hemodynamically significant patent ductus arteriosus, intraventricular hemorrhage (IVH > gradeIII), retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), duration of support and mortality were also compared. METHODS: This was a single center randomized controlled trial. Stratified randomization was done for 216 neonates, based on the gestational age in two subgroups 26-33 weeks and 34-40 weeks whopresented with respiratory distress within 5 days of birth, to receive either NIPPV or CPAP. Primary and secondary outcomes were documented. RESULTS: Statisticalsignificant difference was noted for primary outcome (RR 0.48 [confidence interval = 0.301-0.786], p = 0.003) but not for other secondary outcomes. NIPPV appeared superior in respect to noninvasiveventilation days, BPD occurrence and hospitalization duration. CONCLUSION: As a primary mode, nonsynchronized NIPPV was more efficacious than CPAP in preventing intubation within 72 h of initiation of respiratory support. Further multicenter studies are warranted to explore the benefits of this respiratory support.

RESUMEN

Fetal or neonatal cardiac tumors are rarely encountered in neonatal practice. Moreover, these can be the earliest manifestation of underlying systemic conditions, such as tuberous sclerosis. Cardiac tumors are primarily diagnosed by characteristic findings in transthoracic echocardiography. However, these findings are not absolute, and histopathology remains the gold standard in diagnosing cardiac tumors. Sometimes, doubtful imaging findings can delay the diagnosis and initiation of definitive management. We describe a case of fetal and neonatal cardiac tumor where histopathology served as a benchmark in making a diagnosis and helped in identifying the underlying systemic disease.

RESUMEN

Routine practice of delayed cord clamping (DCC) is the standard of care in vigorous neonates. However there is no consensus on the recommended approach to placental transfusion in non-vigorous neonates. In this trial, we tried to examine the effect of cut umbilical cord milking (C-UCM) as compared to early cord clamping (ECC) on hematological and clinical hemodynamic parameters in non-vigorous preterm neonates of 30-35 weeks gestation. The primary outcome assessed was venous hematocrit (Hct) at 48 (± 4) hours of postnatal age. The important secondary outcomes assessed were serum ferritin at 6 weeks of age, mean blood pressure in the initial transitional phase along with important neonatal morbidities and potential complications. In this single centre randomized controlled trial, 134 non vigorous neonates of 30-35 weeks gestation were allocated in a 1:1 ratio to either C-UCM (n = 67) or ECC (n = 67). For statistical analysis, unpaired Student t and Chi square or Fisher's exact test were used. The mean Hct at 48 h was higher in the C-UCM group as compared to the control group, 50.24(4.200) vs 46.16(2.957), p < .0001. Also significantly higher was the mean Hct at 12 h, 6 weeks and mean serum ferritin at 6 weeks of age in the milked group (p < .0001). Mean blood pressure at 1 h and 6 h was also significantly higher in the milked arm. Need for transfusion and inotropes was less in the milked group but not statistically significant. No significant difference in potential complications was observed between the groups.    Conclusion: C-UCM stabilizes initial blood pressure and results in higher hematocrit and improved iron stores. It can be an alternative to DCC in non-vigorous preterm neonates of 30-35 weeks' gestation. Further large multicentric studies are needed to fully establish its efficacy and safety.   Trial registration: CTRI/2021/12/038606; registration date December 14, 2021. What is Known: • DCC is the routinely recommended method of placental transfusion for vigorous neonates but no consensus exist for neonates requiring resuscitation at birth. • C-UCM is easier to perform in non-vigorous neonates but there is paucity of studies in the preterm population. What is New: • C-UCM is effective as well as safe in non-vigorous preterm neonates of 30-35 weeks gestational age. • C-UCM holds promise as an alternative to DCC, especially in resource limited settings and in situations where the later is not feasible.

RESUMEN

The late preterm infants (34 0/7 to 36 6/7 weeks of gestation) account for at least 70% of all preterm birth. Our aim was to detect growth and neurodevelopment outcome, incidence of neurodevelopmental disability, and its association with maternal and neonatal risk factors among sick late preterm population. Two hundred and ninety-nine late preterm infants were followed up till corrected 2 years of age in this retrospective cohort study. Assessment was done by anthropometry and Developmental Assessment Scale for Indian Infants (DASII) scale at corrected 2 years of age. Presence of visual and hearing impairment, cerebral palsy, and overall neurodevelopmental impairment were also recorded. At 2 years of corrected age, average motor development quotient (DMoQ) was 93.55 (95% CI 90.9 to 96.20) and average mental development quotient (DMeQ) was 89.59 (95% CI 87.13 to 92.04). The incidence of bilateral severe to profound hearing loss and visual loss were found in 6 (2%) and 4 (1.33%) infants, respectively. Severe neurodevelopmental impairment was found in 19 (6.35%) infants. Central nervous system disease and sepsis were found as independent predictors of moderate to severe neurodevelopmental disability.   Conclusion: Late preterm infants admitted in neonatal units were at risk of growth and neurodevelopmental impairment requiring close neurodevelopmental follow-up. In a resource limited setting, this may best be achieved by using DASII in follow-up clinic. What is Known: • Late preterm infants are at a high risk of prematurity-related morbidities. • There is increased risk of cognitive defect, learning difficulties, and behavior problems found at school age for sick late preterm infants. What is New: • Central nervous system disease and sepsis were found as independent predictors of early moderate to severe neurodevelopmental impairment for sick late preterm infants in developing countries like India.

RESUMEN

The purpose of this study is to validate lung ultrasound score (LUS) for prediction of surfactant replacement therapy (SRT) in Indian infants of 27-336/7 weeks gestational age (GA). This prospective diagnostic accuracy study was conducted in a level 3 neonatal care unit in India. Consecutively born preterm infants with respiratory distress syndrome (RDS) were enrolled. Surfactant was administered if oxygen requirement exceeded > 30%. Baseline characteristics, respiratory parameters, and lung ultrasound images were recorded soon after admission and compared between surfactant and non-surfactant groups. Adjusted odds ratio (OR) and diagnostic accuracy of LUS were calculated for SRT. Among 78 infants with RDS included in the final analysis, 62 received surfactant (79.48%). Median time of performing lung ultrasound was 50 min of life in both groups. Median LUS in the anterior and posterior chest areas of either side as well as total LUS was significantly higher in the surfactant group. After adjusting for other confounders, LUS was found to be a significant predictor of SRT (adjusted OR (95%CI): 1.55 (1.15-2.087)). Diagnostic accuracy of LUS was determined by receiver operating characteristic (ROC) curve analysis (AUC (95% CI): 0.751 (0.64-0.842), p < 0.001). A cutoff score of ≥ 9 for LUS was considered optimal for SRT (sensitivity (95%CI): 70.97% (57.87-81.45), specificity (95%CI): 68.75% (41.48-87.87)). CONCLUSION: Lung ultrasound is a valid diagnostic tool for SRT in Indian setting with a cutoff score ≥ 9. TRIAL REGISTRATION: CTRI/2021/11/038269. WHAT IS KNOWN: • Surfactant requirement in preterm infants with RDS has been traditionally based on FiO2 criteria. • Lung ultrasound score can predict the need for surfactant although majority of the studies originated in developed countries. WHAT IS NEW: • Lung ultrasound is a valid tool for surfactant replacement therapy even in developing countries like India.

RESUMEN

ABSTRACT: Biliary atresia (BA) is the most common cause of the obstructive type of neonatal cholestasis that requires prompt surgical intervention. About 10% of neonates with BA have other congenital anomalies, of which splenic malformation (BASM) is a well-known distinct sub-group. There is sparse literature on the association of duodenal atresia and ductal plate malformation (DPM) in patients of BASM. We describe a BASM associated with DPM and duodenal atresia in a 35-day-old infant, who succumbed at 40 days, before portoenterostomy could be performed. Duodenal atresia can be one of the associated malformations associated with BASM and ductal plate abnormalities. In our case, the child did not survive.

RESUMEN

Background: As India reduced maternal mortality by 50% in the last decade, the mental health of mothers has slowly started catching our attention. Increased participation of women in the economic sector and awareness of women's rights has added to this process. Perinatal depression has been associated with negative birth outcomes and poor child development. The paucity of research from eastern India poses challenges for physicians and hinders effective medical interventions. Aim: To investigate the effect of antenatal and postnatal depression on child development at 12 months of age. Method: In total, 174 mothers were administered Bengali Edinburgh Postnatal Depression Scale (EPDS-B) for assessment of antenatal and postnatal depression. Developmental Assessment Scale in Indian Infants (DASII) was administered to assess the motor and cognitive development of their children (n = 153) at 12 months. Result: The prevalence of antenatal and postnatal depression was 28.7% and 16.7%, respectively. Antenatal depression predicted postnatal depression (b = 0.631). Mothers with AD scored significantly low on family support measures (P = 0.012). Children of mothers with AD had low motor and cognitive attainment at the age of 12 months (P = 0.022). Conclusion: Screening and treatment of mental health need to be included in the antenatal care routine to facilitate appropriate child development.

RESUMEN

Fetal and perinatal autopsies are useful to identify the accurate cause of death and in the process recognize disorders which may require counselling for future pregnancies. Abnormalities of the CNS are an important cause of fetal loss and perinatal deaths. Most of these are structural abnormalities of the CNS, however a smaller portion show changes pertaining to prematurity, infections and even congenital tumors. In this review we evaluate CNS abnormalities of the fetus and the newborn as detected in autopsy series. We also describe our experience in a tertiary care hospital with a specialized neonatology unit over the last 8 years and discuss some of the newer methods like virtual autopsy.

RESUMEN

BACKGROUND: Increased use of colistin in healthcare necessitates studies on the trend of colistin resistance and the underlying mechanisms. OBJECTIVES: To understand the susceptibility trend and molecular mechanisms of colistin resistance in neonatal isolates over a 12 year period. METHODS: Colistin susceptibility, mRNA expression, whole genome sequence and mutational analysis was performed. Phylogenomic comparison with a global collection of colistin-resistant Klebsiella pneumoniae strains (n = 70) was done. RESULTS: Of 319 Enterobacterales (K. pneumoniae and Escherichia coli) studied, colistin resistance was found in 9 K. pneumoniae (2.8%). The transmissible colistin resistance gene, mcr, was absent. Colistin-resistant K. pneumoniae belonged to diverse sequence types (ST14/37/101/147/716) and exhibited multiple mechanisms of colistin resistance including overexpression of the two-component systems (TCS) (phoP/Q, pmrA/B), and AcrAB-TolC pump and its regulators. Mutations in TCS, mgrB, pumps, repressors, and lipopolysaccharide-modifying genes were detected. Phylogenomic comparison revealed that this global collection of colistin-resistant K. pneumoniae was diverse, with the presence of epidemic and international clones. Mutations in mgrB and TCS noted in global strains were comparable to the study strains. Co-occurrence of carbapenem resistance (n = 61, 87%) was observed in global strains. Co-existence of dual carbapenemases (blaNDM-5 with blaOXA-48/181) in multiple lineages within different replicons was found in neonatal colistin-resistant study isolates only. CONCLUSIONS: Colistin resistance both in study and global strains is multifaceted and attributed to mutations in chromosomal genes leading to lipopolysaccharide modification or efflux of colistin through pumps. With no transmissible mcr, prevalence of colistin-resistant strains was low in this unit. Colistin-resistant strains with dual carbapenemases causing sepsis are alarming as they are practically untreatable.

RESUMEN

INTRODUCTION: Currently, there is no consensus regarding analgesic premedication before the surfactant administration by less invasive surfactant application (LISA) procedure. In this randomized controlled trial, we compared the level of comfort of preterm infants receiving fentanyl as analgesic and sedative versus no fentanyl during LISA procedure. METHODS: We randomized 34 preterm infants of 28+0-33+6 weeks of gestation with respiratory distress syndrome (RDS) within 6 h of birth to receive either fentanyl (1 µg/kg intravenous) or no premedication during surfactant administration by LISA procedure. Primary objective was to assess the proportion of preterm infants to be comfortable during the procedure [revised premature infant pain profile (R-PIPP) score ≤12] and secondarily complications occurring during the procedure, hemodynamically significant patent ductus arteriosus (hsPDA), intraventricular hemorrhage (IVH) (≥ grade 3), bronchopulmonary dysplasia (BPD) and composite outcome of BPD/mortality. RESULTS: Proportion of preterm infants with a R-PIPP score ≤12 during LISA was significantly higher in the fentanyl group [15/17 (88.23%) vs. 8/17 (47.05%); p value 0.025]. There were no differences in secondary outcome parameters. CONCLUSION: Low-dose fentanyl during LISA procedure resulted in more comfort in preterm infants and without increased complication of both the LISA procedure and fentanyl administration. Further studies are needed to determine the safest and most effective pharmacologic measures to prevent pain and discomfort during LISA.


Respiratory distress syndrome (RDS) in neonates is associated with prematurity, and surfactant administration is essential for its management. Surfactant instillation through a thin intratracheal catheter in spontaneously breathing infants with nasal continuous positive airway pressure (nCPAP) is known as less invasive surfactant application (LISA). Till date, there is no consensus regarding analgesic premedication before the surfactant administration by LISA procedure. In this randomized controlled trial, we compared the level of comfort of preterm infants receiving fentanyl as analgesic and sedative versus no fentanyl during LISA procedure. We reported that proportion of preterm infants with severe pain during LISA was significantly lower in the fentanyl group. There were no differences in clinical outcome parameters. So, we concluded that low-dose fentanyl during LISA procedure resulted in more comfort in preterm infants and without increased complication of both the LISA procedure and fentanyl administration.

RESUMEN

Infantile myofibromas (IMs) are benign soft-tissue tumors of children. They are of fibroblastic-myofibroblastic origin and show considerable morphological overlap with other spindle cell neoplasms. Here, we present two cases of solitary myofibromas, one in a neonate and one in a 2-year-old girl. A 2-day-old girl presented with severe respiratory distress and died during intubation. At autopsy, a myofibroma involving the oropharynx with extension up to the larynx was noted. Second case was a 2-year-girl with a myofibroma in the hard palate. IM must be differentiated from other benign and malignant spindle cell tumors of infancy and childhood. Oropharyngeal myofibroma should be considered in the differentials of neonatal respiratory distress.

RESUMEN

Investment in Early Childhood Development (ECD) is essential for the progress of a nation. In 2013, the Rashtriya Bal Suraksha Karyakram (RBSK) was launched for community level screening, early identification and management of chronic diseases (birth defects, diseases, deficiencies, developmental delays and disabilities) from birth to 18 years. Health care is provided in District hospitals with Special Newborn Care Units, and District Early Intervention Centers (DEIC). Infants are screened at delivery points, or at home under the Home-Based New-born Care package. Pre-schoolers and school aged children are evaluated by mobile health teams using standardized tools in anganwadi centers and schools, respectively. Referrals are managed at higher centers. The DEIC uses an evidence based, trans-disciplinary, collaborative approach for delay/disability at zero expense. Other initiatives disseminating awareness about healthy family practices promoting ECD during pregnancy and the first two years of life include: a booklet 'Journey of First 1000 days'; an android App 'Ayushman Bhava'; ECD call centers that provide individualized counselling related to queries; the LaQshya program that promotes mother-friendly labour; and a more illustrative 'Mother and Child Protection Card' that assists in developmental monitoring. Till date, RBSK has developed two Nodal Collaborating Centers (the Kolkata centre has trained 852 personnel), 234 DEIC's, and 11,000 mobile health teams. Over 6 years (2014 -2020), cumulatively 45,64,31,984 children < 6 years have been screened, 13,95,618 delays /disabilities identified, and 3,04,300 children managed appropriately. The future holds further expansion, development of state-of-the-art specialized centers, collaborative research, and self-sustaining capacity building of multi-disciplinary personnel.

RESUMEN

Thanatophoric dysplasia type 1 (TD1) is a lethal form of osteochondral dysplasia due to mutation of FGFR3 gene. In addition to severe shortening of the limbs there is temporo-occipital lobe dysplasia along with a range of other CNS anomalies. In this report we describe the radiological and anatomical features at autopsy in neonate with TD1 along with the CNS anomalies. We have also summarized the key distinguishing features of TD1 from other common types of osteochondral dysplasia. An accurate diagnosis is important for genetic counseling and impact on future pregnancies.

RESUMEN

Early and successful extubation prevents several morbidities in preterm newborns. Several secondary non-invasive respiratory modalities exist but with their merits and demerits. Given the benefits of nasal high-frequency oscillatory ventilation (nHFOV), we tried to examine whether nHFOV could reduce reintubation rates compared to nasal intermittent positive pressure ventilation (NIPPV) during the post-extubation phase in preterm infants. Stratified randomisation based on gestational age was done for 86 mechanically ventilated preterm infants between 26 and 36+6 weeks of gestation within 2 weeks of age to receive either nHFOV or NIPPV post-extubation. The main objective was to compare extubation failure within 72 h following extubation and secondarily feed intolerance, intraventricular haemorrhage (IVH) (> grade 3), composite bronchopulmonary dysplasia (BPD)/mortality, composite duration of oxygen supplementation/ventilation support and SpO2/FiO2 ratio. No statistical difference was noted for primary outcome (RR 0.8, 95% CI: 0.23 to 2.78; p = 1.00) and secondary outcomes. However, nHFOV appeared possibly better in respect to feed tolerance rates and pCO2 washout.Conclusion: Extubation failure within 72 h in infants less than 37 weeks of gestation did not differ between the two groups. However, nHFOV seems promising in reducing enteral feeding issues and pCO2 elimination. Larger multicentre studies are required for exploring benefits of nHFOV.Trial registration: www.ctri.nic.in id CTRI/2019/07/020055, registration date July 5, 2019 What is Known: • NIPPV is superior to nCPAP as a secondary mode of respiratory support. • Synchronisation is preferred for optimum ventilation. What is New: • nHFOV, a novel non-invasive respiratory modality without need for synchronisation, appears promising as a secondary mode subject to further trials. • It seems promising in reducing enteral feeding issues and pCO2 elimination.

RESUMEN

Antimicrobial resistance in neonatal sepsis is rising, yet mechanisms of resistance that often spread between species via mobile genetic elements, ultimately limiting treatments in low- and middle-income countries (LMICs), are poorly characterized. The Burden of Antibiotic Resistance in Neonates from Developing Societies (BARNARDS) network was initiated to characterize the cause and burden of antimicrobial resistance in neonatal sepsis for seven LMICs in Africa and South Asia. A total of 36,285 neonates were enrolled in the BARNARDS study between November 2015 and December 2017, of whom 2,483 were diagnosed with culture-confirmed sepsis. Klebsiella pneumoniae (n = 258) was the main cause of neonatal sepsis, with Serratia marcescens (n = 151), Klebsiella michiganensis (n = 117), Escherichia coli (n = 75) and Enterobacter cloacae complex (n = 57) also detected. We present whole-genome sequencing, antimicrobial susceptibility and clinical data for 916 out of 1,038 neonatal sepsis isolates (97 isolates were not recovered from initial isolation at local sites). Enterobacterales (K. pneumoniae, E. coli and E. cloacae) harboured multiple cephalosporin and carbapenem resistance genes. All isolated pathogens were resistant to multiple antibiotic classes, including those used to treat neonatal sepsis. Intraspecies diversity of K. pneumoniae and E. coli indicated that multiple antibiotic-resistant lineages cause neonatal sepsis. Our results will underpin research towards better treatments for neonatal sepsis in LMICs.

RESUMEN

Retinopathy of prematurity (ROP), particularly severe ROP is a health concern. The study is aimed to ascertain the magnitude, profile, and outcome of ROP over 5 years at a level II neonatal unit in a district of West Bengal. From 2012 to 2016, a total of 691 newborns with birth weight (BW) <2000 g and/or gestational age < 35 weeks of a district level II neonatal care unit were screened for ROP. Retrospective analysis of these screened babies was performed using the principles of descriptive and inferential statistics. Overall, 38.5% of newborns had any stage ROP and13.2% severe ROP. Two-thirds of babies with severe ROP were <1250 g of BW. About 16.2% of the ROP cases suffered from aggressive posterior ROP (APROP). Oxygen and prematurity were found as significant risk factors. Substantially high occurrence of severe ROP and APROP warrants appropriate measures. Timely screening and intervention with referral to the neonatal ROP unit can improve the scenario.

RESUMEN

The coronavirus disease (COVID-19) pandemic has ramifications for the delivery of newborn nutrition and care services. World Health Organization recommends continuation of breastfeeding in these difficult times, with due precautions. If direct breastfeeding is not possible, milk expression should be explored. Pasteurized donor human milk from milk banks may be fed if mother's own milk is not available. To universalize access to human milk, the Indian government has proposed the establishment of comprehensive lactation management centers/milk banks, lactation management units, and lactation support units at all levels of the public health system. Due to COVID-19, these centers are encountering additional challenges cutting across interventions of rooming in, breastfeeding, milk expression, and provision of donor milk and kangaroo mother care. We discuss issues faced and alleviation measures taken by these centres in relation to provision of an exclusive human milk diet for infants during the pandemic.
