The etiology and risk factors of convulsive status epilepticus in pediatric patients of tertiary center in Saudi Arabia.

OBJECTIVES: To assess the etiology of status epilepticus (SE) among the pediatric patients of a tertiary center in Jeddah, Kingdom of Saudi Arabia (KSA). METHODS: Data from 88 cases was obtained retrospectively from 2006 to 2017 from King Abdulaziz University Hospital (KAUH). Patients aged between 28 days and 14 years with the symptoms of SE were selected for this study. RESULTS: The data show that the proportions of SE etiologies were 30.5% for febrile seizure, 11.9% for electrolytes imbalance, 8.5% for hydrocephalus, 6.8% for CNS infections, and 6.8% for neoplasm. The other etiologies of SE were trauma, fever, intractable epilepsy, cerebrovascular accident, hemorrhagic stroke, etc. There were no clear etiologies in 8 cases. Most of the patients were not of Saudi origin (64.3%), boys (67.8%), and had generalized epilepsy types (91.8%), and 58.6% of the patients complied with epilepsy medications. CONCLUSION: The most prevalent etiology of convulsive status epilepticus was a febrile seizure, followed by electrolyte imbalance and hydrocephalus. However, a nationwide study in KSA must be conducted to determine the major etiologies of SE for its effective management and prevention. Educating families and patients regarding antiepileptic drugs is necessary.

Electrocardiographic changes following intracranial haemorrhage: a retrospective cohort study.

OBJECTIVE: To improve the understanding of the association between electrocardiographic (ECG) abnormalities and clinical outcomes of patients with all types of intracranial hemorrhage (ICH). METHODS: A retrospective cohort study was conducted in a tertiary healthcare hospital on patients with ICH without cardiac disease or renal disease requiring dialysis. Demographic and clinical data were collected from hospital records. ECG record were obtained within 24 hours of presentation and prior to treatment. Records were interpreted for this study by a cardiologist blinded to other data. RESULTS: Assessment of 291 patients (228 adults and 63 children) showed that subdural hemorrhage was the most common type of ICH (31.6%) followed by intraparenchymal hemorrhage (23.0%). ECG records were available for 98 patients. ECG abnormalities were most commonly nonspecific ST-segment changes (32.6%). In adults, history of neurological disease was associated with atrioventricular block (p=.004) and QTc prolongation (p=.041). Pediatric patients exhibited associations between ST-segment changes (p=.045) and sinus tachycardia (p=.027) and type of ICH. However, ECG changes were not statistically associated with clinical outcomes in adults or children. CONCLUSION: Significant ECG changes frequently occurred in patients with all types of ICH but did not consistently predict the outcome in this study. Close observation of patients is still recommended to detect ECG changes that could affect the treatment.
