Surgery for infants with catastrophic epilepsy: an analysis of complications and efficacy.

PURPOSE: Infants with epilepsy often have a catastrophic course. There is a reluctance to operate in the very young, due to the perception of an unacceptable risk of morbidity with early operations. The purpose of this investigation was to better characterize the efficacy and safety of epilepsy surgery in infants. METHODS: Epilepsy operations performed on children under 1 year old, between 2002 and 2013, were reviewed for demographic information, epilepsy characteristics, surgical approach, outcomes, and surgical complications. RESULTS: Twenty-five patients, ages 11 days to 11.5 months (mean 4.7) at operation, were identified. All had daily seizures. Twenty-two (88%) had an abnormal magnetic resonance imaging (MRI). Sixteen (64%) patients underwent hemispherotomy at initial operation. Seven (28%) infants had grid placement followed by focal resection. Focal cortical dysplasia was the most common pathology (40%) followed by hemimegalencephaly (32%). Complications occurred in 36% of patients. These included hydrocephalus in five patients (20%). Two patients had significant intra-operative complications which required unplanned staging of their operations. Both recovered without permanent injury. Mean follow-up was 62.4 months. Twenty patients (80%) are seizure-free, and 10 (40%) are off anticonvulsant medication. Two patients are Engel class 2, and the remaining three patients were Engel class 4, one of whom died with status epilepticus from the contralateral hemisphere. CONCLUSION: Infants with localization-related catastrophic epilepsy can have excellent outcomes from early epilepsy surgery. Complications are common in this patient group and proper diagnosis can be challenging. Young age should not exclude infants with catastrophic epilepsy from consideration for early surgical intervention.

Spontaneous intraventricular hemorrhage associated with prolonged diosmin therapy.

BACKGROUND: The prevalent use of anticoagulation in a growing elderly population has led to an increasing incidence of intracerebral hemorrhage. Furthermore, the understanding of the interactions and adverse effects of oral anticoagulants when used with non-FDA approved drugs is limited. Diosmin is one such non-FDA approved drug which is a semisynthetic, phlebotropic supplement with multiple microcirculatory effects. We report a case of a patient on oral anticoagulation and diosmin, who presented with spontaneous intraventricular hemorrhage, and discuss the possible etiology behind this rare event. METHODS: A retrospective chart review and a comprehensive search of the literature using the PubMed database were performed. RESULTS: A 77-year old female with a 6 week history of warfarin therapy and a several year history of diosmin use presented with severe bitemporal headache. Computed tomography scan revealed an acute hemorrhage within the right ventricle without associated intraparenchymal hemorrhage. International normalized ratio measured 1.8 and was corrected using fresh frozen plasma and vitamin K. She was discharged without neurological deficits. CONCLUSIONS: Diosmin inhibits platelet aggregation and prolongs the effect of norepinephrine on venous tone, leading to increased venoconstriction. The combined effect of chronic microcirculatory hypertension and inhibition of platelet aggregation due to diosmin may have predisposed to spontaneous hemorrhage in this anticoagulated patient. Individual cases such as this serve as a reminder that over-the-counter dietary supplements may be associated with serious adverse events. The practicing clinician should be aware of this possible adverse event when evaluating patients on oral anticoagulation and chronic diosmin treatment.

Primary Multifocal Gliosarcoma of the Spinal Cord.

Gliosarcoma (GS) is a rare and exceedingly malignant neoplasm of the central nervous system. It displays clinical features similar to glioblastoma, yet is histologically unique as it harbors both gliomatous and sarcomatous cellular components. Involvement of the neuro-axis is predominantly limited to the cerebral parenchyma and meninges. Primary GS of the spinal cord is rarely encountered. We report a case of a 54 year old male who presented with 2 months of progressive, bilateral lower extremity sensory deficits. Magnetic resonance imaging of the neuro-axis revealed multiple intradural lesions involving the cervical and thoracic spinal cord without evidence of intracranial involvement. Surgical resection of a dural based, extramedullary cervical lesion and two exophytic, intramedullary thoracic lesions revealed gliosarcoma, WHO grade IV. The patient died approximately 11 months after presentation. This report confirms that GS is not limited to supratentorial involvement and can primarily affect the spinal cord.
