Neonatal Seizure Pattern, Outcome, and its Predictors Among Neonates Admitted to NICU of Ayder Comprehensive Specialized Hospital, Mekelle, Tigray, Ethiopia. Int J Gen Med 2023; 16:4343-4355. [PMID: 37781273 PMCID: PMC10540696 DOI: 10.2147/ijgm.s414420] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 09/16/2023] [Indexed: 10/03/2023] Open
Abstract
Background Seizure is the most frequently observed symptom of neurological disorders and an important determinant of outcome during neonatal period. In clinical practice, it is prevalent and observed in neonates admitted to hospital in low-resources countries, but due to the paucity of studies in these regions, little is known about its pattern, clinical outcomes of hospitalization, and its predictors. Therefore, aims to evaluate seizure patterns, clinical outcomes, and its predictors among neonates admitted to the NICU of ACSH, Mekelle, and Tigray. Methods A hospital-based cross-sectional study design was conducted among neonates with neonatal seizures admitted to NICU of Ayder Comprehensive Specialized Hospital. Data collection was done from record reviews. SPSS Version 25 was used. Descriptive statistics and bivariate logistic regressions where a p-value of <0.05 is considered statistically significant. Results Out of 1622 NICU admissions, 155 (9.6%) were cases of neonatal seizure. The most frequently observed types of seizure in this study were subtle 70 (45.1%) and tonic 49 (31.6%) respectively. At the end of hospitalization 70.3% of neonates were discharged improved, 21.3% of neonates died and 8.4% of neonates had severe neurologic deficits. Poorly controlled seizures (AOR 4.8, 95% CI 2.6-9.2), prolonged duration of labor (AOR 4.3, 95% CI 2.2-8.8) and seizure onset <72 hours (AOR 3.7, 95% CI 1.6-8.5), respectively, were found to be independent predictors of poor neonatal outcome. Conclusion Of all neonatal admissions, neonatal seizure was observed in close to 9.6%. The most frequently observed type of seizure was subtle. Of those admitted neonates, 30% had poor outcomes following the end of their hospitalization or when they leave against medical advice for lack of improvement). Poorly controlled seizures, prolonged duration of labor, and seizure onset <72 hours were independent predictors of poor neonatal outcomes.

Abstract
BACKGROUND Perinatal asphyxia is a prominent cause of neonatal mortality in the developing world. Growth in head circumference is associated with improved neurodevelopment. Previous studies found a positive correlation between additional dietary supplementation and growth in head circumference among newborns with perinatal brain injury. This study aims to evaluate the association between anthropometric parameters and developmental outcomes in newborns with hypoxic ischemic encephalopathy (HIE). METHODS Newborns at ≥36 weeks gestation with moderate to severe HIE were included in the study and growth parameters were monitored. Newborns with life-threatening anomalies were excluded. None of the study participants received therapeutic hypothermia (TH). Developmental Assessment Scale for Indian Infants (DASII) was used to evaluate neurodevelopmental outcomes at 1 year of age. RESULTS Of 76 study participants, 46 were followed for 12 months, 28 died, and 2 were lost to follow-up. HIE stage III, Apgar score <5 at 5 minutes of age, pH ≤ 7.1 on first blood gas and base deficit > - 16 was associated with death or disability at 1 year of age. All anthropometric parameters were significantly lower in presence of death or disability. pH ≤ 7.1 at birth (odds ratio: 11.835, 95% CI 2.273-61.629, p = 0.003) and weight gain at one year (odds ratio 1.001, 95% CI 1.000-1.002, p = 0.03) were significantly associated with death and disability. CONCLUSION pH > 7.1 at birth, and weight gain were associated with better neurodevelopmental outcomes at 1 year of age. Thus, in addition to TH, nutritional interventions may potentially improve outcomes among newborns with HIE.

Abstract
UNLABELLED Although brain injury after neonatal encephalopathy has been characterised well in high-income countries, little is known about such injury in low- and middle-income countries. Such injury accounts for an estimated 1 million neonatal deaths per year. We used magnetic resonance (MR) biomarkers to characterise perinatal brain injury, and examined early childhood outcomes in South India. METHODS We recruited consecutive term or near term infants with evidence of perinatal asphyxia and a Thompson encephalopathy score ≥6 within 6 h of birth, over 6 months. We performed conventional MR imaging, diffusion tensor MR imaging and thalamic proton MR spectroscopy within 3 weeks of birth. We computed group-wise differences in white matter fractional anisotropy (FA) using tract based spatial statistics. We allocated Sarnat encephalopathy stage aged 3 days, and evaluated neurodevelopmental outcomes aged 3½ years using Bayley III. RESULTS Of the 54 neonates recruited, Sarnat staging was mild in 30 (56%); moderate in 15 (28%) and severe in 6 (11%), with no encephalopathy in 3 (6%). Six infants died. Of the 48 survivors, 44 had images available for analysis. In these infants, imaging indicated perinatal rather than established antenatal origins to injury. Abnormalities were frequently observed in white matter (n = 40, 91%) and cortex (n = 31, 70%) while only 12 (27%) had abnormal basal ganglia/thalami. Reduced white matter FA was associated with Sarnat stage, deep grey nuclear injury, and MR spectroscopy N-acetylaspartate/choline, but not early Thompson scores. Outcome data were obtained in 44 infants (81%) with 38 (79%) survivors examined aged 3½ years; of these, 16 (42%) had adverse neurodevelopmental outcomes. CONCLUSIONS No infants had evidence for established brain lesions, suggesting potentially treatable perinatal origins. White matter injury was more common than deep brain nuclei injury. Our results support the need for rigorous evaluation of the efficacy of rescue hypothermic neuroprotection in low- and middle-income countries.

Abstract
This was a retrospective review to determine predictors of outcome in term infants with hypoxic ischaemic encephalopathy (HIE) at the University Hospital of the West Indies. Ninety-five neonates fulfilled criteria for entry into the study of these 34 (36%) had a poor outcome. The stage of encephalopathy, seizures on admission, the need for more than one antiepileptic for seizure control and an abnormal neurological examination at hospital discharge were found to be associated with poor outcome. Multiple logistic regression analyses showed that an abnormal neurological examination at discharge was the only independent predictor of poor outcome. Babies who had an abnormal neurological examination at hospital discharge were more likely to have a poor outcome (odds ratio 2.6, confidence interval 0.03-0.4). An abnormal neurological examination at discharge had a positive predictive value of 88% and a negative predictive value of 84% for poor outcome, with a sensitivity and specificity of 60 and 96%, respectively. We recommend that if post-HIE, an infant has an abnormal neurological examination at the time of discharge from hospital, that infant should be followed up and monitored in a specialist neurology clinic and parents counselled about the guarded prognosis for normal neurodevelopmental outcome.

Abstract
BACKGROUND/AIMS Post-asphyxia neonatal encephalopathy (NE) is one of the main causes of disabilities in term-born infants. This review attempted to investigate the developmental outcomes of term-born infants with post-asphyxia NE. METHOD An electronic search on various databases identified 13 empirical studies against the selection criteria modified from the consensus statement from the International Cerebral Palsy Task Force. RESULTS The overall quality of methodology of these studies was average. The random effect meta-estimate of the proportion of infants having adverse developmental outcomes such as death, cognitive impairment, sensory-motor impairments was 47% (95% CI 36-57%). Significant heterogeneity (I(2)=87.7%, p<0.00001) between studies indicated variations in number of subjects in studies and their characteristics. For those studies using the Sarnat grading of NE, the proportion of infants with adverse outcomes was nil in stage 1 (mild) NE, 32% in stage 2 (moderate) and almost 100% in stage 3 (severe) NE. CONCLUSIONS At present, researchers are using very loose diagnostic criteria of perinatal asphyxia and post-asphyxia NE, making the study samples heterogeneous. Clinicians and researchers are urged to make use of the recent consensus statement regarding diagnostic criteria for intrapartum asphyxia and to identify these high-risk infants for early intervention.

Abstract
Hypoxic Ischemic Encephalopathy (HIE) score may be used to predict neurodevelopment outcome in infants with birth asphyxia. A total of 140 infants who had a 5 min Apgar score of <7 at birth had detailed motor and neurodevelopment assessment. Outcome measures were grouped as normal or abnormal with morbidity (convulsions, abnormal muscle tone and delayed development) or death. The positive predictive value (PPV) for mortality was 42.3% for moderate HIE and 93.8% for severe HIE. For severe HIE the PPV was 100%. Thirteen infants had delayed development, the score had PPV of 63.6% for moderate HIE and 100% for severe HIE. The best correlation with outcome was the peak score of 15 or higher had a PPV of 100%. Specificity was found to be 100% and sensitivity of 14%. The HIE scoring system is a useful predictor of neurodevelopment outcome at 6 months of age in a resource poor setting.

Abstract
UNLABELLED Neonatal encephalopathy (NE) following perinatal asphyxia (PA) is considered an important cause of later neurodevelopmental impairment in infants born at term. This review discusses long-term consequences for general cognitive functioning, educational achievement, neuropsychological functioning and behavior. In all areas reviewed, the outcome of children with mild NE is consistently positive and the outcome of children with severe NE consistently negative. However, children with moderate NE form a more heterogeneous group with respect to outcome. On average, intelligence scores are below those of children with mild NE and age-matched peers, but within the normal range. With respect to educational achievement, difficulties have been found in the domains reading, spelling and arithmetic/mathematics. So far, studies of neuropsychological functioning have yielded ambiguous results in children with moderate NE. A few studies suggest elevated rates of hyperactivity in children with moderate NE and autism in children with moderate and severe NE. CONCLUSION Behavioral monitoring is required for all children with NE. In addition, systematic, detailed neuropsychological examination is needed especially for children with moderate NE.

Abstract
Pregnancy in women with epilepsy (WWE) is known to be associated with a higher risk of congenital malformations than is associated with pregnancy in non-epileptic women. Several factors have been identified to account for the increased risk, including the direct teratogenic effects of antiepileptic drug (AED) therapy, indirect effects of these drugs by interfering with folate metabolism, genetic abnormalities in drug or folate metabolism, and possibly an arrhythmogenic effect of maternal drug therapy on the embryonic heart, leading to ischaemia in developing tissues. A harmful effect of maternal seizures on the developing embryo has not been proven, although seizures and status epilepticus account for most of the excess maternal mortality in women with epilepsy. Abrupt withdrawal of drug therapy by the mother may be an important contributory factor. Less is known about the psychomotor development of children born to mothers with epilepsy because few studies have been designed to follow their progress throughout childhood. Retrospective studies suggest that impaired cognitive development may be associated with maternal drug therapy, particularly valproate. There is an urgent need to evaluate these risks and, with this in mind, several prospective registers have been set up to collect data from pregnancies in women with epilepsy.

Abstract
BACKGROUND Perinatal asphyxia remains an important condition with significant mortality and long-term morbidity. Multisystem involvement including hypotension and low cardiac output is common in infants with perinatal asphyxia. Dopamine is commonly used for infants with hypotension of any etiology, with the goal of improving cardiac output and preventing its detrimental consequences. OBJECTIVES To determine if dopamine, compared to placebo, no treatment, volume or another inotrope reduces morbidity and mortality in term newborn infants with suspected perinatal asphyxia. SEARCH STRATEGY The standard search strategy of the Neonatal Review Group was used. Searches were conducted of the Oxford Database of Perinatal Trials, Cochrane Controlled Trials Register (The Cochrane Library, Issue 1, 2002), MEDLINE (1966 to March 2002), previous reviews including cross references, abstracts and conference proceedings (Perinatal Society of Australia and New Zealand 1998-2002 and Pediatric Academic Societies meetings 1998-2001). SELECTION CRITERIA Randomised controlled trials comparing dopamine with placebo, no treatment, other inotropic agents, or volume in infants greater than 36 weeks gestation. Perinatal asphyxia could be suspected on the basis of a cord blood pH < 7.0, cord blood base excess < -16 mEq/L or 5 minute Apgar score < 6. DATA COLLECTION AND ANALYSIS Standard methods of the Cochrane Neonatal Review Group with use of relative risk (RR), risk difference (RD) and weighted mean difference (WMD). The fixed effects model using RevMan 4.1 was used for meta-analysis. Data from individual studies were only eligible for inclusion if at least 75% of participants were followed up. MAIN RESULTS Only one study (DiSessa 1981) was eligible. This study compared low dose dopamine at 2.5 mcg/kg/min with placebo (dextrose in water). This study enrolled 14 term infants with a 5 minute Apgar <6 and a systolic BP >=50 mmHg at a mean of 10 hours age. Seven infants only were randomised to treatment with dopamine and seven to receive placebo. No significant differences between these two groups were found for mortality or long term neurodevelopmental outcome. Length of hospitalisation was not significantly different between the two groups. No study was found that examined the effect of dopamine in infants with evidence of cardiovascular compromise, nor were any studies identified in which dopamine was compared to other inotropic agents for term infants with suspected asphyxia. REVIEWER'S CONCLUSIONS There is currently insufficient evidence from randomised controlled trials that the use of dopamine in term infants with suspected perinatal asphyxia improves mortality or long-term neurodevelopmental outcome. The question of whether dopamine improves outcome for term infants with suspected perinatal asphyxia has not been answered. Further research is required to determine whether or not the use of dopamine improves mortality and long-term morbidity for these infants and if so, issues such as which infants, at what dose and with what co-interventions should be addressed.

Abstract
BACKGROUND The primary aim of this study was to find widely available, inexpensive, and non-invasive parameters for early identification or prediction of the infants with hypoxic-ischemic encephalopathy (HIE) who will have a severe adverse outcome (classified as death or a major neurological deficit). METHODS Fifty-seven full-term or near-term newborn infants with a diagnosis of HIE were consecutively admitted to the neonatal intensive care unit and studied. Occurrence of seizures during the first 24 h, cranial ultrasonography (US) findings within the first 5 days of life, and Denver developmental screening test II (DDST II) at 6 months of age, were analyzed in relation to mortality and neurological status at 2 years of age. RESULTS Of the 57 infants, 10 were lost to follow-up. Twenty of the remaining 47 infants had a severe adverse outcome. Among the predictors of severe adverse outcome, occurrence of seizures was found to have a poor predictive accuracy. Cranial US had 100% sensitivity, however with a rather low specificity (55%). However, DDST II at 6 months of age, yielded a very high predictive accuracy (sensitivity=100%, specificity=95%). CONCLUSION We conclude that DDST II at 6 months of age could be used in predicting severe neurological outcome in infants with HIE.
