ObjectiveTo define nomograms for blood pressure in Egyptian children and adolescents.Methods and study designA total of 60 025 Egyptian children from birth to 19 years were enrolled in this cross-sectional randomised study from December 2015 to March 2017. They were selected from diverse geographical districts in Egypt. Healthy children who fulfilled the inclusion criteria, which included good nutritional history, absence of fever or documented underlying disease at the time of examination, no evidence of haemodynamically significant illness, and no antihypertensive drugs or other chronic drug administration, were included in the study. Body weight, recumbent length (for less than 24 months) and height (from 2 years to 19 years), and blood pressure were measured using standard mercury sphygmomanometers.ResultsBlood pressure increases with age in both boys and girls. The 90th percentile of systolic and diastolic blood pressure among Egyptian children was different from other ethnic populations (American and Turkish children) in both sexes. Systolic and diastolic blood pressure showed a positive correlation with weight and height in both sexes (p<0.001).ConclusionWe assumed that normal blood pressure curves should be used cautiously during childhood, and it is recommended that every population have its own normal standard curve to define measured blood pressure levels in children. These centiles increased our knowledge and awareness of normal blood pressure among Egyptian children and adolescents. The percentiles will distinguish children and young adolescents with increased blood pressure and will be of value to both medical practice and scientific research.
Critically ill children frequently develop CIP/CIM, mostly of axonal polyneuropathy pattern, which compromises rehabilitation and recovery and is associated with a number of comorbidities.
Background Epilepsy is a neurological disease that requires long-term antiepileptic drugs (AEDs). The old generation of AEDs may affect serum homocysteine and asymmetric dimethylarginine (ADMA) and disturb lipid levels. The aim of the study was to evaluate serum ADMA, homocysteine, lipid profile, and carotid intima-media thickness (CIMT) in epileptic children. Methods This study was implemented on 159 epileptic children who were subdivided into 3 subgroups, with 53 receiving sodium valproate, 53 receiving levetiracetam, and 53 receiving polytherapy, for over 6 months and 53 healthy children. Results Low-density lipoprotein, triglycerides, and cholesterol levels were increased in epileptic children (p < 0.001), which were higher in those receiving multidrug followed by a valproate receiver. While high-density lipoprotein was lower in those receiving multidrug more than those receiving valproate. ADMA and homocysteine levels increased in epileptic patients than in controls (p < 0.001). Higher ADMA was also observed in the multidrug receiver (5.78 ± 0.62), followed by the levetiracetam group (5.56 ± 0.61). Homocysteine levels were significantly higher in multidrug and valproate-treated children than those treated with levetiracetam. CIMT was significantly higher in multidrug and valproate-treated patients (p < 0.001). Conclusions Long-term use of AEDs, especially old-generation polytherapy, can elevate lipid profiles, homocysteine, ADMA levels, and carotid intima-media thickness compared to the minimal effect of new AEDs. Impact The long-term use of antiepileptic drugs, especially old-generation polytherapy, can increase lipid profiles, homocysteine levels, ADMA, and carotid intima thickness compared to the minimal effect of new antiepileptic generation. A routine follow-up of these markers and a lifestyle modification are recommended to avoid cerebrovascular events as much as possible.
<P>Background: Autism Spectrum Disorders (ASD) as a considerable health obstacle in kids is characterized by compromised social collaboration and stereotyped behavior. Autism is triggered by an interactive impact of environmental and genetic influences. Presumably, some inborn errors of metabolism are implicated in a sector of developmental disabilities. Also, several trace elements may have an important role in human behavior and neurological development. This study was designed to verify the frequency of inherited metabolic disorders and/or trace element abnormalities in children with ASD. </P><P> Methods: In a retrospective analytical study, 320 children diagnosed with ASD according to the DSM-V criteria and Childhood Autism Rating Scale criteria were enrolled in this study. Serum ammonia, blood lactate, and arterial blood gases, plasma amino acid profile by tandem mass spectrophotometry, and a urinary organic acid assay were performed in all the patients. Likewise, the estimation of a number of trace elements in the form of serum lead, mercury, copper, and plasma zinc was done in all the patients. </P><P> Results: A total of 320 children with ASD, inherited metabolic disorders were identified in eight (2.5%) patients as follows: seven (2.19%) patients with phenylketonuria, and one (0.31%) patient with glutaric aciduria type 1. Regarding the trace element deficiency, sixteen (5%) patients presented low plasma zinc level, five (1.56%) children presented a high serum copper level, two (0.62%) children presented a high serum lead level and only one (0.31%) autistic child presented high serum mercury level. Electroencephalogram (EEG) abnormalities were reported in 13.12% and Magnetic Resonant Imaging (MRI) abnormalities in 8.43% of cases. </P><P> Conclusion: Screening for metabolic diseases and trace elements is required in all children diagnosed with ASD irrespective of any apparent clinical attributes of metabolic complaints and trace elements discrepancies.</P>
Background The risk of neurological complications is increased in children with sickle cell disease (SCD), such as silent cerebral infarction (SCI) and stroke. Brain-Derived Neurotrophic Factor (BDNF) is a nerve growth factor associated with elevated transcranial Doppler (TCD) velocities and increased risk of stroke in SCD patients. So, we assessed the BDNF level in children with SCD and its relation to neurological complication as silent stroke. Methods A comparative cross-sectional study was conducted on 40 patients with SCD, recruited from the Hematology Unit, Pediatric Department, Menoufia University Hospital, and 40 healthy children as controls. Laboratory investigations including BDNF were done. TCD was done for all patients and Magnetic Resonance Imaging (MRI) was done on high-risk patients. Results BDNF levels were significantly higher in children with SCD than in controls with a significant relation to TCD findings. There was a statistically significant diagnostic ability of BDNF in the prediction of SCD complications as its sensitivity was 89.5%, specificity (95% CI) was 80% with a cut-off point >0.69, AUC = 0.702, and p = 0.004). Conclusion Serum BDNF levels were higher in sickle disease patients who had abnormal transcranial Doppler. BDNF had a significant diagnostic ability in the detection of SCD complications. Impact Silent stroke is a very serious complication in children with sickle cell disease, so regular follow up should be every six months. BDNF is considered a potential biomarker for stroke risk prediction in patients unable to receive TCD.
