Background: Neonatal seizures contribute significantly to newborn morbidity and mortality particularly in developing countries including Nigeria. Unfortunately the countries with high incidence of neonatal seizures often lack the facilities to adequately diagnose, monitor and prognosticate the condition. Objective: We set out to determine the factors at presentation that predict death among babies admitted with clinically identifiable seizures. Methods: We prospectively observed consecutive neonatal admissions over a nine month period at the Wesley Guild Hospital, Ilesa, Nigeria. Babies with seizures were identified based on clinical observation. Perinatal history, examination and laboratory findings were compared between babies with seizures who survived and those that died. Multivariate regression analysis was used to determine the predictors of mortality. Results: Over a nine month study period, a total of 340 babies were recruited out of which 55 (16.7 percent) had clinically identifiable seizures. Fifteen (27.3 percent) of the 55 babies with clinically identifiable seizures died; while 20 (7.0 percent) of the 285 babies without seizures died. Clinically identifiable neonatal seizures contributed to 42.9 percent of the overall mortality in the neonatal unit during the study period. The risk factors for mortality among the babies with seizures were clinical seizures in the first 24 hours of life, birth asphyxia co-existing with hyponatraemia and presence of cerebral oedema (P < 0.05). The independent determinant of mortality among babies with clinical seizures was cerebral oedema (OR = 4.025; 95% CI 1.342-26.956; P = 0.019). Conclusion: We conclude that clinically identifiable neonatal seizures contribute significantly to neonatal mortality and presentation within 24 hours of delivery, birth asphyxia and cerebral oedema increased the risk of death in babies with seizures.

Objectives: The prevalence of obesity is rapidly increasing among Indian children, who, in general, are more prone to develop metabolic complications at an early age. Valproate and phenytoin are commonly used antiepileptic drugs in children. This study aimed to assess the parameters of the metabolic syndrome in Indian children with epilepsy on valproate or phenytoin monotherapy. Methods: This cross-sectional study recruited children from the Pediatric Epilepsy Clinic, Department of Pediatrics, Kalawati Saran Children Hospital, New Delhi from March 2012 to September 2012. All consecutive children diagnosed with epilepsy as per International League Against Epilepsy definition aged 3-18 years on valproate or phenytoin monotherapy for at least 6 months were enrolled at a tertiary care children's hospital in Northern India. After clinical and anthropometric evaluation (including body mass index [BMI] and waist circumference), the blood samples were analyzed for fasting serum glucose, total cholesterol, high-density lipoprotein-cholesterol, and serum triglyceride. Results: Children with BMI >95 th centile and waist circumference >90 th centile were not significantly different among children on valproate and phenytoin monotherapy. Children on valproate had significantly higher mean serum triglyceride (96.9 mg/dL vs. 77.6 mg/dL; P < 0.001) and total cholesterol (148.3 mg/dL vs. 132.8 mg/dL; P = 0.002) levels as compared to children on phenytoin monotherapy. Conclusions: The lipid abnormalities may be observed in children on valproate or phenytoin therapy and may warrant periodic screening.

Background: The purpose of this study was to use the National Cancer Institutes' Surveillance, Epidemiology, and End Results (SEER) database to perform a large-scale analysis of brainstem anaplastic astrocytoma (AA) and glioblastoma multiforme (GBM). Use of the SEER database gave us a larger sample size of this rare tumor type, allowing for the analysis of the relationship between prognostic factors and survival. Materials and Methods: We selected pediatric patients (<18 years old) from the SEER database with histologically confirmed diagnoses of primary high-grade gliomas (World Health Organization Grade III/IV) of the brainstem. In univariate and multivariate analysis, we analyzed the relationship between demographic (age, gender, race, diagnosis date), histologic (AA, GBM), and treatment (surgery, radiation) factors on survival. Results: In our cohort of 124 patients, those with AA had a median survival of 13 months and those with GBM 9 months. Higher-grade tumors were associated with statistically significantly increased mortality (hazard ratio [HR]: 1.74, confidence intervals [CIs]: 1.17-2.60). Surgical intervention was associated with a significantly lower mortality, either alone (HR: 0.14, CI: 0.04-0.5) or in combination with radiation (HR: 0.35, CI: 0.15-0.82). Radiation therapy alone was significantly associated with decreased mortality within the first 9 months after diagnosis but not with overall mortality. No demographic characteristics were significantly associated with mortality. Conclusions: Outcome remains poor in the pediatric high-grade brainstem glioma population. Survival is correlated with lower-grade tumor histology, radiation therapy only in the first 9 months after diagnosis, and surgical resection.

Huntington's disease (HD) is a rare dominantly inherited neurodegenerative disorder characterized clinically by a combination of abnormal involuntary (choreic) movements, neuropsychiatric manifestations, and dementia. It is caused by an unstable CAG repeat expansion in the gene IT15 which encodes a Huntingtin protein. We present a case of a 9 year old boy who had developmental regression starting from the age of 8 years of age along with resistant seizures and signs of cerebellar involvement with absence of chorea and is on anticonvulsants, baclofen, and tetrabenzine. As is expected in a case of childhood-onset HD, our patient is rapidly deteriorating and is currently in the terminal phase of his illness along with resistant convulsions.

Background: Pediatric intramedullary spinal cord lesions are not only rare but also different from adults in a number of aspects. We aimed to study the incidence and the frequencies of various pediatric intramedullary mass lesions, their outcome to treatment and the factors determining their outcome of treatment. Materials and Methods: Thirty-one consecutive children (aged 1-18 years, mean 11.1 years, male: female = 1.8:1) with pathologically proven intramedullary spinal cord lesions treated at our center were studied. Clinico-radiological, histopathological, operative, and outcome data were reviewed retrospectively. The functional status was assessed using the modified McCormick grading system. Results: Gross total tumor excision was performed in 19 patients (61.3%), subtotal in 9 patients (29%), partial excision was performed in 2 (6.5%) patient, and only biopsy was performed in 1 patient (6.5%). There was one peroperative death, 2 patients died at follow-up. Complications included wound related complications (n = 4), transient deterioration in the motor power, and respiratory complication requiring a tracheostomy. Six patients showed recurrence at a mean follow-up of 16.4 months. Developmental tumors, high-grade ependymomas, and incompletely excised grade 2 ependymomas showed a tendency to recur. Conclusions: Children constituted nearly 1/5 th (17.4%) of intramedullary spinal cord tumors. Astrocytomas and ependymomas taken together constituted the most common intramedullary spinal lesions in children; however, developmental tumors predominated in the first decade. Children usually presented in good functional grades preoperatively and maintained good grades after surgery. Functional outcome was dependent on the preoperative neurological status and histopathology of the lesions.

Background: Craniosynostosis (CS) syndrome is an autosomal dominant condition classically combining craniosynostosis and non-syndromic craniosynostosis with digital anomalies of the hands and feet. The majority of cases are caused by heterozygous mutations in the third immunoglobulin-like domain (IgIII) of FGFR2, whilst a larger number of cases can be attributed to mutations outside this region of the protein. Aims: To find out the FGFR1, FGFR2, FGFR3 and FGFR4 gene in craniosynostosis syndrome. Settings and Design: A hospital based prospective study. Materials and Methods: Prospective analysis of clinical records of patients registered in CS clinic from December 2007 to January 2015 was done in patients between 4 months to 13 years of age. We have performed genetic findings in a three generation Indian family with Craniosynostosis syndrome. Results: We report for the first time the clinical and genetic findings in a three generation Indian family with Craniosynostosis syndrome caused by a heterozygous missense mutation, Thr 392 Thr and ser 311 try, located in the IgII domain of FGFR2. FGFR 3 and 4 gene basis syndrome was eponymously named. Genetic analysis demonstrated that 51/56 families to be unrelated. In FGFR3 gene 10/TM location of 1172 the nucleotide changes C>A, Ala 391 Glu 19/56 and Exon-19, 5q35.2 at conserved linker region the changes occurred pro 246 Arg in 25/56 families. Conclusions: Independent genetic origins, but phenotypic similarities in the 51 families add to the evidence supporting the theory of selfish spermatogonial selective advantage for this rare gain-of-function FGFR2 mutation.

Children with medulloblastomas most commonly present with signs and symptoms of elevated intracranial pressure due to obstructive hydrocephalus, especially headaches and vomiting. However, some pediatric patients present with sudden neurological deterioration due to intracerebellar hemorrhage associated with medulloblastoma, although very few reports exist that document this phenomenon. An 8-year-old girl was admitted to our emergency department who presented with sudden loss of consciousness, vomiting, and bradycardia. The neuroradiological evaluation revealed a hemorrhagic mass lesion in the posterior fossa. Urgent evacuation of the hematoma was performed. The postoperative course was uneventful, and the postoperative histopathological examination revealed the lesion to be a medulloblastoma. This report presents an unusual case of a medulloblastoma presenting with fatal intracranial hemorrhage in a child. The clinical features and intraoperative and pathologic findings of the case are discussed.
