Hepatic Injury in Neonates with Perinatal Asphyxia

Background: Perinatal asphyxia (PA) is a major cause of morbidity and mortality in which dramatic transient impairment in liver functions occurs in some patients. Objectives: We aimed to evaluate the state of the liver in cases of Perinatal asphyxia and to assess the severity of hepatic impairment in relation to different grades of HIE. Patients and Methods: This case-control study was conducted on 100 full-term newborns with perinatal asphyxia (Group I) and 50 healthy neonates served as controls (Group II). All biochemical parameters of liver function were measured on the 1st, 3rd, and 10th day after birth. These parameters include serum alanine transferase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), total protein, serum albumin, serum bilirubin (total and direct), and international normalized ratio (INR), in both cases and controls. Results: Among babies with PA, 25 (25%) had an Apgar score of 0 to 3 (severe PA), 43 (43%) had an Apgar score of 4 to 5 (moderate PA) and 32 (32%) had an Apgar score of 6 to 7 (mild PA) at 5 minutes of life. HIE was found in 39% among cases of PA and the remaining 61% were normal. Among babies with PA and HIE; 25.7% had stage I, 41% had stage II and 33.3% had stage III. Impaired liver function was reported in 48% of asphyxiated babies. On the first day of life, ALT, AST, ALP, LDH, PT, and INR were significantly higher in Group I compared to Group II. However, total protein and serum albumin were significantly lower in Group I compared to Group II. ALT and AST showed a positive correlation with the severity of HIE. On the third day of life, LDH rises as the stage of HIE progressed from stage 0 to stage 3. The difference in LDH among most stages of HIE was statistically significant. Conclusion: Liver enzymes can be used as an easy early diagnostic marker to differentiate between babies with asphyxia and those without asphyxia. Also, liver enzymes can be used for the detection of the severity of PA.

Risk Factors of Intractable Epilepsy in Children with Cerebral Palsy

OBJECTIVES

We aimed to investigate the risk factors predicting the development of intractable epilepsy in children with cerebral palsy (CP), with an emphasis on perinatal characteristics, seizure semiology, imaging, and EEG findings.

MATERIALS & METHODS

Following a descriptive, retrospective, case-control design, 106 children with CP and epilepsy from 2015 to 2020 were studied (46 children with CP and intractable epilepsy and 60 with CP and controlled epilepsy). Data were retrieved from medical records of participants (i.e., demographics, clinical characteristics, perinatal history, etiology of seizure and CP, seizure semiology, intellectual functions, therapeutic options, brain imaging, and EEG findings).

RESULTS

We established a model of the most important risk factors that can predict intractable epilepsy in children with CP. The model included the additive effect of a poor Apgar score at 5 minutes, the presence of neonatal seizures, focal epilepsy, and focal slowing on the EEG background (Area under the receiver operating characteristic of 0.810).

CONCLUSION

The findings can be used to identify intractable epilepsy in children who suffer from CP with further support by offering early therapeutic interventions intended to reduce the burden of refractory seizures.

Serum Neuron-specific Enolase and S100 Calcium-binding Protein B in Pediatric Diabetic Ketoacidosis

Objective

Neuron-specific enolase (NSE) and S100 calcium-binding protein B (S100B) are markers of different neurological disorders. The aim was to investigate the relationship between NSE and S100B serum concentrations and the severity of diabetic ketoacidosis (DKA) in diabetic children.

Methods

Eighty children with DKA, 40 with type 1 diabetes mellitus (T1DM) without DKA and 40 healthy controls were enrolled. Severity of DKA was assessed according to blood pH and bicarbonate concentration. Serum NSE and S100B were measured in all participants. In the DKA group serum NSE and S100B were measured at three time points, at admission and at 12 hours and 24 hours after starting treatment.

Results

Children with DKA showed significantly higher serum levels of NSE at all time points compared to children with T1DM without DKA and controls (p<0.01), while serum S100B concentrations did not differ between the three cohorts. Children with T1DM but without DKA also had significantly higher serum levels of NSE (p<0.01) compared to healthy controls. Patients with low Glasgow Coma Scale score (GCSS) and those with moderate and severe DKA had significantly higher levels of NSE at all time points (p<0.01 for each) compared to patients with normal GCSS and those with mild DKA. No significant differences were found in serum S100B levels according to the severity of DKA and GCS (p>0.05). Younger age, lower GCSS, higher glucose and HbA1c, lower pH and lower serum bicarbonate were the risk factors associated with elevated NSE.

Conclusion

Serum NSE is elevated in all patients with type 1 DM and, in patients with DKA, correlates with severity of DKA. However, serum S100B concentration did not differ between T1DM with or without DKA and healthy controls.

Impact of Vitamin D Supplementation on Attention-Deficit Hyperactivity Disorder in Children

BACKGROUND

The role of nutrients and dietary factors in attention-deficit hyperactivity disorder (ADHD) remains unclear.

OBJECTIVES

The primary objective was to evaluate the serum vitamin D level in children with a diagnosis of ADHD. The secondary objective was to detect the effect of vitamin D supplementation on cognitive function in those with vitamin D deficiency.

METHODS

A total of 50 children with ADHD and 40 healthy controls were included in the study. We measured the serum level of vitamin D. Patients with vitamin D deficiency were subdivided into 2 groups: one with vitamin D supplementation and the other without vitamin D supplementation. Further assessment and follow-up of children with ADHD was done. The Wisconsin Card Sorting Test, Conners' Parent Rating Scale, and Wechsler Intelligence Scale for Children were performed at baseline and follow-up in all cohorts with an ADHD diagnosis.

RESULTS

The diagnosis of vitamin D deficiency was significantly greater in children with ADHD compared with the control group ( P < 0.05). Children with ADHD had significantly ( P = 0.0009) lower values of serum vitamin D (17.23 ± 8.98) than the control group(31.47 ± 14.42). The group receiving vitamin D supplementation demonstrated improvement in cognitive function in the conceptual level, inattention, opposition, hyperactivity, and impulsivity domains.

CONCLUSION

Vitamin D supplementation in children with ADHD may improve cognitive function.
