Flicker Stimulus

Abstract Purpose It is well known that repetitive flash stimulation may trigger seizures in susceptible individuals. Nevertheless, reports of such incidents occurring during recording of a flash electroretinogram (ERG) are extremely rare. Here, we describe the case of a photic-induced seizure triggered during an ERG recording in the absence of a history of epilepsy or other paroxysmal events. Methods A 14-year-old male patient presented with reduced visual acuity and impaired mesopic vision. Ophthalmological exams confirmed the patient’s complaints but were inconclusive as to the underlying pathophysiology. An ERG recording was performed, during which the 30-Hz flicker stimulus triggered a seizure. Results The ERG was essentially normal, with the exception of a 7-Hz rhythm superimposed onto the flicker ERG response that was recorded when the seizure developed. Conclusions The present case highlights the possibility that the 30-Hz ERG flash stimulus triggers a seizure in patients with no previous paroxysmal events. Literature evidence suggests that the likelihood of such an incident could be reduced by stimulating monocularly.

: Inflammatory bowel diseases (IBDs) are chronic conditions characterized by unknown etiology and pathogenesis with deregulation of mucosal immunity. Among possible treatments, corticosteroids, already available from the 50’, are still the mainstay of treatment for moderate-severe disease. Nonetheless, the use of steroids is still largely empirical and solid evidence about therapeutic schemes are lacking. Moreover, due to the important side-effects and for the unsatisfactory impact on long-term natural history of disease, the steroid sparing has become an important therapeutic goal in IBD management. Besides conventional steroids, the so called “low bioavailability” steroids, which are steroids with high affinity for peripheral receptors and elevated hepatic first-pass metabolism, have demonstrated efficacy and more favorable safety profile. In the present review of the literature evidence of efficacy and safety of conventional and low bioavailability steroids in IBD patients are evaluated, and practical suggestions for a correct use in clinical practice are presented according to the current clinical guidelines.

History Of Epilepsy

In a previously described population of 314 autistic and 237 dysphasic nonautistic children, after exclusion of 12 autistic girls with Rett syndrome, 14% (42 of 302) of autistic children and 8% (19 of 237) of dysphasic children had epilepsy (P = .03). The major risk factors for epilepsy were severe mental deficiency and the combination of severe mental deficiency with a motor deficit. In autistic children without severe mental deficiency, motor deficit, associated perinatal or medical disorder, or a positive family history of epilepsy, epilepsy occurred in 6% (10 of 160) which was analogous to the 8% (14 of 168) found in similar dysphasic nonautistic children. The language subtype of verbal auditory agnosia is associated with the highest risk of epilepsy in autistic (41%, 7 of 17) and dysphasic (58%, 7 of 12) children. The higher percentage of epilepsy in autistic girls, 24% (18 of 74) compared with boys 11% (25 of 228) (P = .003), is attributed to the increased prevalence of cognitive and motor deficit in girls. Once the risk attributable to associated cognitive and motor disabilities is taken into account, there is no difference in the risk of epilepsy between autistic and nonautistic dysphasic children.

Background: Dalfampridine extended release (DAL) is a broad-spectrum voltage-gated potassium channel blocker that is indicated in multiple sclerosis to improve the nerve conduction of demyelinated axons. Seizures are a known side effect of DAL, which is contraindicated in patients with a history of epilepsy. Objective: Three cases of multiple sclerosis (MS) with de novo convulsive status epilepticus (CSE) probably related to dalfampridine administration are described. Methods: No patients had a history of seizures or renal impairment. Biological tests were normal. A brain magnetic resonance imaging (MRI) showed diffuse cortical and subcortical atrophy without active inflammatory lesions. Results: All three patients presented with CSE that was attributed to DAL and so was discontinued. Conclusion: These case reports illustrate that, aside from seizures, de novo CSE is a potential complication of MS patients treated with DAL.

Underlying Pathophysiology

A 25-year-old Bangladeshi lady presented to neurology with a three-month history of involuntary movements of her right arm, associated with loss of power. There was progression to the right leg, and she subsequently developed episodes of slurred speech and blurred vision. At the time of presentation, she was 12 weeks pregnant and the symptoms were reported to have started at conception. Past medical history was unremarkable apart from one first trimester miscarriage and there was no significant family history suggestive of a hereditary neurological condition. MRI of the head revealed no abnormalities but serology showed positive antinuclear antibodies (ANAs) at a titre of 1/400. Further investigations revealed strongly positive anticardiolipin antibodies (>120) and positive lupus anticoagulant antibodies. The patient had a second miscarriage at 19 weeks gestation strengthening the possibility that the chorea was related to antiphospholipid antibody syndrome and she was started on a reducing dose of Prednisolone 40 mg daily and aspirin 300 mg daily. Six months later, she had complete resolution of neurological symptoms. There are several reports of chorea as a feature of antiphospholipid syndrome, but no clear consensus on underlying pathophysiology.

Ewing sarcoma is a malignant bone tumor that mainly affects children, adolescents and young adults with more than 1.5 cases per million worldwide. Approximately 20-25% of patients present metastatic disease at the diagnosis, that is often resistant to intensive therapy.We present the case of a 19-year-old male with history of epilepsy who started his condition with weight loss, increased volume, pain, swelling after receiving surgical treatment due to a left distal femur fracture, showing tomographic evidence of a 50-cm tumor with multiple lung lesions, so disarticulation was performed with the Boyd technique, obtaining histopathological result of Ewing’s Sarcoma, and was subsequently sent to the medical oncology service for follow-up and adjuvant treatment with significant clinical and radiological improvement in pulmonary metastatic activity.

The Individual

BackgroundPsychosis often develops after the administration of antiepileptic drugs (AEDs) in patients with epilepsy. However, the individual vulnerability and clinical condition of such patients have been rarely scrutinised. We investigated the effect of individually consistent (trait-dependent) and inconsistent (state-dependent) characteristics.MethodsThe individual characteristics, clinical states and psychotic outcome of patients from eight adult epilepsy clinics were retrospectively reviewed over 6-month periods after a new drug (AED or non-AED) administration between 1981 and 2015.ResultsA total of 5018 new drugs (4402 AEDs and 616 non-AEDs) were used in 2015 patients with focal epilepsy. Subsequently, 105 psychotic episodes (81 interictal and 24 postictal) occurred in 89 patients. Twelve patients exhibited multiple episodes after different AED administrations. Trait-dependent characteristics (early onset of epilepsy, known presumed causes of epilepsy, lower intellectual function and a family history of psychosis) were significantly associated with the patients who exhibited psychosis. Absence of family history of epilepsy was also associated with psychosis but not significantly. Subsequent logistic regression analysis with a model incorporating family history of psychosis and epilepsy, and intellectual function was the most appropriate (p=0.000). State-dependent characteristics, including previous psychotic history and epilepsy-related variables (longer duration of epilepsy, AED administration, higher seizure frequency and concomitant use of AEDs) were significantly associated with psychotic episodes. Subsequent analysis found that a model including AED administration and previous psychotic history was the most appropriate (p=0.000).ConclusionPsychosis occurring after new AED administration was related to the individual vulnerability to psychosis and intractability of epilepsy.
