Background: Birth asphyxia is one of the important causes of neonatal morbidity and mortality, accounting up to 30% of neonatal death in Nepal. It is also an important cause of long term neurological disability and impairment. Thompson encephalopathy score is a clinical score which can be used to assess the newborn with hypoxic ischemic encephalopathy for the prognosis and their neurodevelopmental outcome. The aim of the study was to assess the role of Thompson score in predicting the early outcome of neonates with birth asphyxia. Methods: A prospective study was conducted from May 2019 to April 2020 in Nepal Medical College. All the term babies during the period with Apgar score of less than seven at five minutes were considered to have birth asphyxia and included in the study. Neurological examination was done on first, second and third day using HIE score proposed by Thompson and severity of hypoxic ischemic encephalopathy was classified accordingly. Outcome was measured as normal, morbidity with encephalopathy, seizure, organ dysfunction and death. Results: Out of 391 newborn admitted to neonatal unit, 84 (21.4%) had birth asphyxia. Mild Thompson score on day 1,2,3 were 49(58.3%), 49 (58.3%), 51(60.7%); moderate Thompson score on day 1,2,3 were 21 (25%), 21 (25%), 18(21.4%) and severe Thompson score on day 1, 2, 3 were 14 (16.7%), 14 (16.7%), 15(17.9%) respectively. Out of 14 babies who had severe Thompson score on day 1, 11(91.7%) expired and 3 (16.7%) developed encephalopathy. Conclusions: There was strong correlation of severity of Thompson score with the outcome. Keywords: Birth asphyxia; hypoxic ischemic encephalopathy; thompson score

Background: The aim of the study was to find out the neurodevelopmental outcome of babies with hypoxic ischemic encephalopathy at 6 months of age and to predict early markers of abnormal neurological outcome in those babies.Methods: 50 babies admitted with hypoxic ischemic encephalopathy were enrolled in this prospective study and followed up at 3 and 6 months of age at Mahatma Gandhi Memorial Government Hospital, Trichy. The neurological outcome of the babies was assessed by CDC grading of motor milestones, Trivandrum development screening chart, Amiel Tison angles head circumference and weight measured. USG cranium was done for all the babies and MRI brain was done in babies with abnormal neuro sonogram and abnormal outcome. Vision and hearing were tested clinically.Results: The incidence of abnormal neurological outcome was 14%. The early markers predicting abnormal neurological sequele are identified.Conclusions: Early identification of abnormal neuro behaviour helps in starting early intervention to improve the long term outcome.

AbstractHypoxic-ischemic encephalopathy (HIE) is a manifestation of perinatal asphyxial insult that continues to evolve over days to weeks following the initial injury. Therapeutic hypothermia has demonstrated that a proportion of this secondary brain injury may indeed be preventable. However, therapeutic hypothermia has also altered the prognostic utility of many bedside tools that are commonly used as predictors of long-term neurodevelopmental outcome in HIE. Clinicians are often confronted with uncertainty when assessing the prognosis of infants with HIE. Improved understanding of the implications and limitations of individual investigations may inform clinical decisions and allow for timely intervention. This review summarizes the predictive value of currently available prognostic markers in HIE infants in the therapeutic hypothermia era, including clinical, biochemical, neurophysiological, physiological, and neuroimaging predictors.

Ischemic Encephalopathy

Objective Hypoxic–ischemic encephalopathy (HIE) is the second cause of neonatal deaths and one of the main conditions responsible for long-term neurological disability. Contrary to past belief, children with mild HIE can also experience long-term neurological sequelae. The aim of this systematic review is to determine the predictive value of long-term neurological outcome of (electroencephalogram) EEG/amplitude-integrated electroencephalogram (aEEG) in children who complained mild HIE. Study Design From a first search on PubMed, Google Scholar, and clinicalTrials.gov databases, only five articles were considered suitable for this study review. A statistical meta-analysis with the evaluation of odds ratio was performed on three of these studies. Results No correlation was found between the characteristics of the electrical activity of the brain obtained through EEG/aEEG in infants with mild HIE and subsequent neurological involvement. Conclusion EEG/aEEG monitoring in infants with mild HIE cannot be considered a useful tool in predicting their neurodevelopmental outcome, and its use for this purpose is reported as barely reliable.

Ischemic Encephalopathy

Hypoxic–ischemic encephalopathy (HIE) remains to be a major cause of long-term neurodevelopmental deficits in term neonates. Hypothermia offers partial neuroprotection warranting research for additional therapies. Kynurenic acid (KYNA), an endogenous product of tryptophan metabolism, was previously shown to be beneficial in rat HIE models. We sought to determine if the KYNA analog SZR72 would afford neuroprotection in piglets. After severe asphyxia (pHa = 6.83 ± 0.02, ΔBE = −17.6 ± 1.2 mmol/L, mean ± SEM), anesthetized piglets were assigned to vehicle-treated (VEH), SZR72-treated (SZR72), or hypothermia-treated (HT) groups (n = 6, 6, 6; Tcore = 38.5, 38.5, 33.5 °C, respectively). Compared to VEH, serum KYNA levels were elevated, recovery of EEG was faster, and EEG power spectral density values were higher at 24 h in the SZR72 group. However, instantaneous entropy indicating EEG signal complexity, depression of the visual evoked potential (VEP), and the significant neuronal damage observed in the neocortex, the putamen, and the CA1 hippocampal field were similar in these groups. In the caudate nucleus and the CA3 hippocampal field, neuronal damage was even more severe in the SZR72 group. The HT group showed the best preservation of EEG complexity, VEP, and neuronal integrity in all examined brain regions. In summary, SZR72 appears to enhance neuronal activity after asphyxia but does not ameliorate early neuronal damage in this HIE model.

AbstractThe mammillary bodies (MB) and hippocampi are important for memory function and are often affected following neonatal hypoxic ischemic encephalopathy (HIE). The aim of this study was to assess neurodevelopmental outcome in 10-year-old children with HIE with and without therapeutic hypothermia. Additional aims were to assess the associations between MB atrophy, brain volumes (including the hippocampi), white matter microstructure and neurodevelopmental outcome at school-age. Ten-year-old children with HIE were included, who were treated with therapeutic hypothermia (n = 22) or would have qualified but were born before this became standard of care (n = 28). Children completed a neuropsychological and motor assessment and MRI. Mammillary bodies were scored as normal or atrophic at 10 years. Brain volumes were segmented on childhood MRI and DTI scans were analysed using tract-based spatial statistics. Children with HIE suffered from neurocognitive and memory problems at school-age, irrespective of hypothermia. Hippocampal volumes and MB atrophy were associated with total and performance IQ, processing speed and episodic memory in both groups. Normal MB and larger hippocampi were positively associated with global fractional anisotropy. In conclusion, injury to the MB and hippocampi was associated with neurocognition and memory at school-age in HIE and might be an early biomarker for neurocognitive and memory problems.

Ischemic Encephalopathy

Introduction: HIE is often clinically suspected in the setting of a known perinatal stress event arising from a complicated or difcult delivery. The most sensitive and specic imaging technique for examining infants with suspected hypoxicischemic brain injury is MR imaging. It also gives information about the timing and specic patterns of injury and also suggest diagnoses other than HIE such as metabolic disorders and developmental disorders of the brain. MRI is also a useful tool in the determination of prognosis and also follow-up of HIE. Aim: This study was undertaken to evaluate the various MRI appearances of hypoxic ischemic encephalopathy in term and preterm neonates and to correlate the MRI appearances with clinical outcome. Materials and Methods: All neonates with history of birth asphyxia, referred for MRI examination to the Department of Radio-Diagnosis, K. R. Hospital attached to Mysore Medical College and Research Institute, during January 2018 to January 2019. All MRI scans were performed on GE optima MR360 1.5 Tesla. Sequences used were T1W axial, T1 FLAIR axial, T2W axial, T2 FLAIR axial, T1W sag, T2W coronal, T2W GRE axial, DWI axial and ADC maps. Results: 30 babies with clinically suspicion of HIE and positive ndings on MR imaging were evaluated in our study. Out of 30 babies, 18 were term and 12 babies were preterm. Periventricular luecomalacia is most common MRI pattern in preterm and central pattern in term neonates. 16 babies had abnormal developmental outcome at 6 months follow up study. 16 babies with diffusion restriction in corpus callosum, 12 had abnormal outcome. 7 out of 10 babies with loss of normal signal in internal capsule had abnormal outcome. Babies with diffusion restriction in basal ganglia had gross developmental delay. Conclusion: MRI is the modality of choice for evaluation of HIE because of excellent gray – white matter resolution, well-depiction of myelination pattern and multi-planar imaging capabilities. There is a strong relation between the MRI appearances of birth asphyxia and the clinical outcome. Therefore MRI has a strong role in prognosticating lesions.
