Introduction: Febrile convulsion is the most common seizure disorder in the pediatric age group. It occurs in 2-5% of children. A febrile seizure is a seizure accompanied by fever (temperature 100.4°F or 38°C by any method), without central nervous system infection, that occurs in infants and children 6 through 60 months of age. Aim: The study was conducted to see the effect of serum sodium level on the recurrence of febrile seizure during the same febrile illness. Materials and Method: A cross-sectional descriptive study which enrolled 65 children admitted with febrile seizures at 100 bed district hospital, Naogaon. They were divided in to two groups, those with a single seizure and the rest were children with more than one seizures. Serum sodium levels were estimated after stabilization of patients. The probability of recurrent febrile seizures and serum sodium level was analyzed. Results: Hyponatremia (serum sodium <135 mmol/l) was seen in 12(18.5%) of 65 children and the remaining 81.5% children had normal serum sodium level (serum sodium 135-145 mmol/l). Among the hyponatremia group all children developed more than one seizure during the same febrile episode. The mean serum sodium level in patients with single and recurrent seizure was 138.48±2.17mmol/l and 135.27±3.11mmol/(P<0.001). The relationship between the probability of a recurrent seizure and serum sodium level is statistically highly significant. Conclusion: Estimation of the seum sodium in children with febrile seizures help in deciding for admission in hospital as well as to predict seizure recurrence within the same febrile episode.

Perinatal asphyxia is a major cause of morbidity and mortality among the newborns in developing countries like Bangladesh. The CNS lesions following perinatal asphyxia can be detected by ultrasonography before closure of fontanels which is easier, cost-effective, and convenient than other methods like CT scan and MRI. This cross-sectional type of descriptive study was conducted on 99 perinatal asphyxiated babies in the Paediatric department of Rajshahi Medical College Hospital during the period of July 2008 to June 2010 to assess CNS lesions in different grades of HIE in term and preterm babies. A non-random purposive sampling method was adopted to select the sample unit. Ultrasonography of the brain of each patient was done at the Centre for Nuclear Medicine & Ultrasound, Rajshahi only once within first 28 days of life when the baby became clinically stable. Ultrasonographic findings showed that 13.1% term babies had abnormal findings of which cerebral edema occupied the major portions (54.54 %). About 20.0% preterm babies had abnormal ultrasonographic findings of which ventriculomegaly without IVH (66.6%).The study also showed that the prevalence of intracranial abnormality was higher (78.6%) among the perinatal asphyxiated babies with HIE stage-2 in comparison to that of the HIE stage-3 (14.3%) and HIE stage-1(7.1%).So, this study provided evidences in favour of role of ultrasonography of brain in the evaluation of perinatal asphyxiated babies and designing appropriate management.TAJ 2016; 29(2): 21-25
