Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Epileptic children with the age ranged 5 up to 15 years who were started and kept up on valproate monotherapy. In this study, a child determined to have nocturnal enuresis based on the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, fourth edition: "an involuntary voiding of urine during sleep, with a severity of at least twice a week, in children aged 5 years or older, in the absence of congenital or acquired defects of the nervous system."

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
NE is one of the side effects of VPA treatment, and it is generally underdiagnosed or overlooked by clinicians. A comprehensive review study, about the effects of valproic acid, did not mention that nocturnal enuresis as an adverse event of the valproate however; more recent study reported variable incidence of VPA-induced NE is 2.2-24%.
The investigator's study, retrospectively evaluate the characteristics of and the risk factors for the occurrence of nocturnal enuresis in epileptic children kept on valproate monotherapy.
Method Participants The study was conducted on 260 children with epilepsy receiving valproate monotherapy aged 5-15 years who attended the outpatient clinic of neurology departments, Mansoura University Hospital, Egypt during the period Sep 2019 to Aug 2019.
Clinical, EEG and laboratory assessment at presentation
* The patients' history, clinical, demographic, and laboratory data were acquired.
* The following tests and imaging studies are routinely done for epilepsy patients receiving valproate treatment and developed nocturnal enuresis, blood urea nitrogen (BUN), serum creatinine (Cr), urinary pH (before and after valproate therapy beginning and at enuresis onset), serum levels and therapeutic doses of valproate.
* Urinary tract ultrasonography (with full and void bladder).
* CT brain and EEG.
* Patients were therefore assessed month to month for a follow up over a time of 6 sequential months, with extra visits as required dependent on seizure recurrence or side effects.
Follow-up at least monthly interval for 6 month for the children kept on valproate monotherapy. Evaluation of seizure control and the reported side effects associated with valproate by the parents were determined. In this way special consideration and directly asking parents about the incidence of NE and its recurrence (daily and monthly) is mandatory.
The time from the initiation of valproate monotherapy to the beginning of NE, the daily dose and the duration of treatment of valproic acid (mg/kg) at the onset of enuresis and the serum level of valproate were reported. Also, the time of cessation of NE either spontaneous or following discontinuation of valproate was determined.
Statistical analysis
A multivariate logistic regression analysis was carried out for the following independent variables: age, weight, body weight, duration of treatment and daily dose of valproate, and serum level valproate. P-value \<0.05 were considered of statistically significant results.
