Background: We aimed to identify the potential risk factors associated with seizure clusters in patients with temporal lobe epilepsy (TLE).Methods: This retrospective cross-sectional study was performed on all the consecutive patients with TLE, who were admitted to the Epilepsy Monitoring Unit (EMU), Loghman-Hakim Hospital, Tehran, Iran. Seizure cluster was defined as three or more habitual seizures occurring within 24 hours, in over 50% of ictal events, with inter-seizure interval of less than 8 hours. The patients’ demographic data, epilepsy duration, seizure frequency, frequency of interictal epileptiform discharges (IEDs), and brain magnetic resonance imaging (MRI) findings were collectedResults: Among a total number of 124 patients with TLE, 62 (50.0%) patients reported seizure clusters. In addition, 44 (37.9%), 42 (36.2%), and 30 (25.9%) patients had normal-appearing brain MRI, mesial temporal sclerosis (MTS), and other brain pathologies, respectively. In terms of IEDs frequency, 35 (29.4%), 43 (36.1%), 17 (14.3%), and 24 (20.2%) patients had respectively frequent, occasional, rare, and no spikes in one-hour of interictal scalp electroencephalography (EEG) recording. In our study, seizure clusters were not associated with the epilepsy duration (P = 0.100), the amount of IEDs (P = 0.764), or MRI findings (P = 0.112).Conclusion: In patients with TLE, seizure clustering had no correlation with the epilepsy duration, the amount of IEDs, or brain MRI findings.

Background: Clinical studies have reported improved neurological outcomes in patients who were taking vitamin D supplements. This study investigates the effect of intramuscular (IM) vitamin D supplementation in patients with acute ischemic stroke (AIS) on neurological outcomes and inflammatory marker levels. Methods: This study included patients diagnosed with AIS (n = 60) from the Neurology Unit of Loghman Hakim Hospital, Tehran, Iran, during the year 2019. Patients with AIS were allocated randomly into two groups who received a single dose of 300000 IU IM vitamin D and a control group that did not receive vitamin D supplementation. Serum vitamin D concentration, interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-α) levels, as primary outcomes, and the Modified Rankin Scale (MRS), the National Institute of Health Stroke Scale (NIHSS), and the Mini-Mental State Examination (MMSE), as secondary outcomes, were measured at the baseline and the end of the study (6 weeks). Results: Eventually, 59 patients with AIS completed the intervention study. A single dose of 300000 IU increased vitamin D level; moreover, vitamin D supplementation improved MRS and IL-6 levels significantly (P = 0.01, P = 0.02, respectively). There were reverse correlations between serum vitamin D and NIHSS and TNF-α after vitamin D administration. However, no statistically significant effect of vitamin D on the TNF-α or NIHSS and MMSE was seen compared to the control group. Conclusion: Vitamin D probably due to a single dose and short duration of administration, as well as a short follow-up period, had no favorable effects on TNF-α level and NIHSS score.
