Ictal religious speech in non-dominant temporal lobe epilepsy: three cases.

Ictal religious speech and gestures, rare ictal semiological findings, sign the epileptic focus at the non-dominant temporal lobe in the literature. Therefore, we aim to present non-dominant temporal lobe semiological findings, including ictal praying and religious gestures in three cases.

Headache in idiopathic/genetic epilepsy: Cluster analysis in a large cohort.

OBJECTIVE: The link between headache and epilepsy is more prominent in patients with idiopathic/genetic epilepsy (I/GE). We aimed to investigate the prevalence of headache and to cluster patients with regard to their headache and epilepsy features. METHODS: Patients aged 6-40 years, with a definite diagnosis of I/GE, were consecutively enrolled. The patients were interviewed using standardized epilepsy and headache questionnaires, and their headache characteristics were investigated by experts in headache. Demographic and clinical variables were analyzed, and patients were clustered according to their epilepsy and headache characteristics using an unsupervised K-means algorithm. RESULTS: Among 809 patients, 508 (62.8%) reported having any type of headache; 87.4% had interictal headache, and 41.2% had migraine. Cluster analysis revealed two distinct groups for both adults and children/adolescents. In adults, subjects having a family history of headache, ≥5 headache attacks, duration of headache ≥ 24 months, headaches lasting ≥1 h, and visual analog scale scores > 5 were grouped in one cluster, and subjects with juvenile myoclonic epilepsy (JME), myoclonic seizures, and generalized tonic-clonic seizures (GTCS) were clustered in this group (Cluster 1). Self-limited epilepsy with centrotemporal spikes and epilepsy with GTCS alone were clustered in Cluster 2 with the opposite characteristics. For children/adolescents, the same features as in adult Cluster 1 were clustered in a separate group, except for the presence of JME syndrome and GTCS alone as a seizure type. Focal seizures were clustered in another group with the opposite characteristics. In the entire group, the model revealed an additional cluster, including patients with the syndrome of GTCS alone (50.51%), with ≥5 attacks, headache lasting >4 h, and throbbing headache; 65.66% of patients had a family history of headache in this third cluster (n = 99). SIGNIFICANCE: Patients with I/GE can be clustered into distinct groups according to headache features along with seizures. Our findings may help in management and planning for future studies.

Diabetic polyneuropathy, deep white matter lesions, and carotid atherosclerosis: is there any association?

The morphologic and functional damages of diabetes mellitus (DM) on microcirculation can play a role in the pathogenesis of both polyneuropathy and cerebral white matter lesions. The aim of this study is to investigate the relation between polyneuropathy and cerebral deep white matter lesions (DWMLs) and carotid atherosclerosis in patients with type 2 DM. Sixty-six patients with type 2 DM without any disorder that may cause polyneuropathy, and vascular risk factors except for DM and hyperlipidemia were included in the study. DWMLs and carotid atherosclerosis were investigated in patients with and without polyneuropathy. Forty patients (60.6%) had diabetic sensorimotor polyneuropathy. DWMLs were more frequent in patients with polyneuropathy compared to patients without polyneuropathy (p = 0.003). Logistic regression analysis confirmed association between polyneuropathy and DWMLs after adjusted for age (p = 0.013), duration of DM (p = 0.007), and both age and duration of DM (p = 0.016). No statistically significant difference was found between patients with and without polyneuropathy for carotid atherosclerosis. Among patients with polyneuropathy, those having DWMLs had higher mean age (p = 0.003) and longer symptom duration (p = 0.020) compared to patients without DWMLs. No association was found between DWMLs and carotid atherosclerosis. Polyneuropathy and cerebral DWMLs in type 2 DM patients may share common pathogenesis; presence and duration of polyneuropathy symptoms may predict ischemic white matter damage independent of carotid atherosclerosis.

Is West Nile Virus infection associated with myasthenia gravis?

BACKGROUND: Myasthenia Gravis (MG) is an autoimmune disease which is characterised by disruption of signal transmission at neuromuscular junction. We aimed to search about a newly reported association between MG and West Nile Virus (WNV) infection. METHODS: We searched WNV IgG by ELISA in serum samples of 50 available MG patients and 38 controls. RESULTS: None of the samples gave positive results for past WNV infection. CONCLUSION: No evidence of past WNV infection was found in our study population of MG patients. This may have been because MG has been showed to be related with neuroinvasive WNV, which none of our study subjects seem to have had based on their stories. New multicentre studies focusing on immunological mechanisms and held with larger groups or especially neuroinvasive disease patients can cast light onto the answer of this question.
