This study was designed to assess brain-derived neurotrophic factor (BDNF) as a possible candidate for enhanced cognition in breastfed infants. The study was conducted on 42 infants, 4-6 months old, who were classified according to their feeding pattern into breastfed group, formula-fed group and mixed-feeding group. Each infant was subjected to history taking, clinical examination, estimation of the level of BDNF by Enzyme-Linked Immunosorbent Assay (ELISA) technique and assessment by Bayley scale of infant development-second edition (BSID-II). The current study revealed that breastfed group had higher BSID-II scores followed by mixed-fed group then formula-fed one, yet these results reached statistical significance only in total behaviour rating scale (TBRS) and Motor Quality Percentile rank values. Additionally, breastfed infants had significantly higher values of BDNF when compared to those receiving formula milk. Negative correlations between BDNF and both weight for age and weight for length scores were detected. Furthermore, significant positive correlation was detected between BDNF and TBRS. Regression analysis studies revealed that breastfeeding is the most determinant factor for BDNF, TBRS and Motor Quality Percentile rank values. Serum BDNF levels are significantly higher in breastfed infants and shows positive correlations with the results of BSID-II. Given that simultaneous increase in brain BDNF occurs due to onsite production, transport from the periphery or both, it is prudent to hypothesize that BDNF could be one of the factors responsible for the enhanced cognition detected in breastfed infants.

The study was conducted on 33 children aged 3-6 years who suffered from protein energy malnutrition (PEM) during infancy in comparison to 30 matching children to assess the long-term deficits in cognition and language skills. The patients' files were revised to record their admission and follow-up data and history, clinical examination, intelligence quotient and language assessment were done. The study revealed that 2-5 years from the acute attack the PEM patients were still shorter than the controls and their cognitive abilities were poorer. Their mental ages and language skills were mostly determined by their height and the duration of follow-up during their acute illness. Additionally their diet after the 3-5 years is still defective and does not meet their recommended daily allowance. These observations urge us to continue following these patients for longer durations to make sure no permanent damage occurs due to the PEM insult to the growing brain.

Objective To assess the clinical and neuroimaging findings of pediatric patients with drug-resistant focal epilepsy, comparing conventional MR technique to the "essential 6” protocol. Methods An observational study of 18 children with drug resistant focal seizures identified both clinically and/or by EEG findings. Available clinical data as well as EEG and MRI data in patients’ files at the pediatric neurology clinic at Ain Shams University was retrospectively evaluated and documented. All patients then underwent a new MRI study using a novel MR technique - the essential six sequence protocol to determine whether the latter technique was superior to standard at picking subtle anatomical abnormalities in children with drug resistant focal epilepsy. Results 18 children (10 males and 8 females) with a mean age of 8.49 ±3.20 years were enrolled. The mean age at onset of epilepsy was 3.24 ±2.79 years. 15 out of 18 patients (83%) had an abnormal EEG. The mean Chalfont Seizure Severity Scale Score was 63.71 ±34.35. There was no statistically significant difference in Chalfont seizure severity scores between patients with normal vs abnormal EEG, and with normal vs abnormal MRI. The novel MRI technique could pick on an abnormality in 12 out of the 18 cases (66%), which is six times more than what could be identified using the baseline/conventional MRI technique. Conclusions The essential 6 MRI protocol is superior to conventional MRI protocols at picking structural abnormalities in patients with drug resistant focal epilepsy.

Background: Although the antioxidant property of vitamin C as well as its endothelial function promotion are well documented, its role in fetal growth during pregnancy is still not conclusive in previous studies. Objectives: This study aimed to estimate maternal and cord blood vitamin C level and to detect its influence on neonatal growth as well as placental weight and placental apoptosis. Methods: The study was conducted on 60 healthy singleton pregnant women and their full term neonates at Ain Shams University Hospital in Egypt. Maternal and cord blood vitamin C plasma level estimation as well as quantitative analysis of placental apoptotic index were done in addition to full anthropometric assessment for delivered neonates. Results: There was a positive significant correlation between maternal and neonatal vitamin C levels (r = 0.838, P < 0.001). Positive significant correlations between maternal vitamin C levels and neonatal weight (r = 0.448 , P < 0.001), length (r = 0.67, P < 0.001), BMI (r = 0.52, P = 0.003), OFC (r = 0.60, P < 0.001) and placental weight (r = 0.373, P < 0.001) while a significant negative correlation with placental apoptotic index (r = À0.817, P < 0.001) were detected. Multiple regression analysis showed that placental weight was the most sensitive predictor of neonatal weight (t = 4.132, P < 0.001) followed by maternal vitamin C (t = 3.034, P = 0.006). Conclusion: Maternal vitamin C level has a significant positive impact on neonatal anthropometry and placental weight while negatively correlating with placental apoptosis. This denotes an important role of vitamin C in fetal and placental growth during pregnancy.

Objective To select patients with drug resistant epilepsy following up in Pediatrics Neurology Outpatient Clinic of Children's Hospital, Ain Shams University who are candidates for epilepsy surgery and to detect outcome of epilepsy surgery in such children as regards seizures control. Methods This prospective study was conducted over a period of 36 months and comprises of 3 stages. Stage 1 includes selection of candidates for epilepsy surgery and preoperative evaluation. Evaluation included clinical assessment, video EEG, MRI epilepsy protocol. Stage 2 include surgery phase where decision of surgery was made by a multidisciplinary team. Stage 3 includes post-operative evaluation as regards Seizures frequency, Seizures Severity using Chalfont score, Engel Epilepsy Surgery Outcome Scale and the International League Against Epilepsy (ILAE) outcome classification. Data was tabulated and analyzed with SSPS package for windows. Results 17 patients underwent epilepsy surgery. Results revealed significant decrease in seizures frequency and severity at 6 and 12 months after surgery. As regards Engel Epilepsy Surgery Outcome Scale 11 (64.7%) patients were class I at 12 months. As regards the ILAE outcome classification 10 (58.8%) patients are class 1 at 12 months. Conclusions epilepsy surgery can be a hope for patients with drug resistant epilepsy who are well selected and evaluated preoperatively. New studies on larger number and for longer duration are recommended.
