Electronegative electroretinogram in the modern multimodal imaging era.

Background: The electronegative electroretinogram (ERG) reflecting inner retinal dysfunction can assist as a diagnostic tool to determine the anatomical location in eye disease. The aim of this study is to determine the frequency and aetiology of electronegative ERG in a tertiary ophthalmology centre and to develop a clinical algorithm to assist patient management.

Methods: Retrospective review of ERGs performed at the Save Sight Institute from January 2011 to December 2020.

[Neurophysiological aspects of multiple hippocampal transection in intractable temporal lobe epilepsy].

Objective: To search for correlations between intraoperative electrocorticographic data and seizure control after the multiple hippocampal transections (MHT) in patients with symptomatic pharmacoresistant medial temporal lobe epilepsy.

Material And Methods: Six patients underwent MHT nearby the hippocampus. The left dominant hemisphere was affected in all cases.

Assessing Residual Cone Function in Retinitis Pigmentosa Patients.

Purpose: The purpose of this study was to investigate cone function deterioration in patients with retinitis pigmentosa (RP) using full field electroretinogram (ffERG), pattern electroretinogram (pERG), and optical coherence tomography (OCT) and their correlation with visual acuity (VA).

Methods: Clinical records (2008-2018) of patients with RP undergoing repeat electrophysiology were reviewed. Results of ffERG (30 Hz flicker and fused flicker amplitude [FFAmp]), pERG [p50 and n95], and macular OCT (ellipsoid zone [EZ] and outer segment thickness) were collected.

[Surgical treatment of epilepsy in children with focal cortical dysplasia].

Objective: Surgery is the first-line treatment option in children with FCD and refractory epilepsy, but the rate of success and patient numbers who became free of seizures vary widely from series to series.

Study Aims: To elicit variables affecting the outcome and predicting achievement of the long-term seizure-free status.

Material And Methods: One hundred sixty-nine children with cortical dysplasia and DR-epilepsy underwent surgery Preoperative evaluation included prolonged video-EEG and MRI (in all patients) and neuropsychological testing when possible.

[Surgical treatment of epilepsy in children with gloneuronal brain tumors: morphology, MRI semiology and factors affecting the outcome].

Introduction: Glioneuronal tumors (GNT) are usually found in children (less than 1.5% of all neoplasms of the brain). With rare exceptions, they are benign and usually manifest only by epilepsy, which is quite often resistant to treatment with AE drugs.
