Surgical Resection for Epilepsy Following Cerebral Gunshot Wounds.

OBJECTIVE: The surgical management of epilepsy after penetrating gunshot wounds (GSWs) to the head has not been described in the modern era. Given the extensive damage to the cranium and cortex from such injuries, the safety and efficacy of surgical intervention are unclear. We report surgical strategy and outcomes after resection for medically refractory epilepsy following GSWs in 4 patients. METHODS: A prospectively compiled database of 325 patients with epilepsy was used to identify patients undergoing surgery for medically refractory epilepsy after a GSW to the brain. Seizure frequency, scalp and intracranial electroencephalography evaluation, type of resection, and seizure outcomes were compiled. RESULTS: All 4 patients underwent direct electrocorticography recordings either with implanted electrodes or intraoperatively that were used to drive surgical decision making. All patients had intracranial shrapnel fragments and large areas of encephalomalacia on imaging. Intracranial electrodes were placed in 2 patients to localize seizure onsets. Two patients underwent frontal lobe resections, and the other 2 patients underwent multilobar resections. Latency between injury and epilepsy surgery was 12 years, and mean age at surgery was 28 years. In all cases, epilepsy surgery led to a significant improvement in seizure control (Engel class I, 2 patients; II, 1 patient; and III, 1 patient). CONCLUSIONS: Epilepsy is common after penetrating head injury, and the incidence is likely to increase given the growing numbers of armed conflicts in urban centers worldwide. In selected cases, intracranial monitoring and surgical resections may be safely performed and can lead to favorable seizure outcomes.

POEMS Syndrome in a Juvenile Initially Diagnosed as Treatment Resistant Chronic Inflammatory Demyelinating Polyneuropathy.

POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) is a disorder that mainly affects adults. We report a pediatric patient, initially considered to have Guillain-Barré syndrome, who continued to have progression of neuropathic disease leading to the diagnosis of chronic inflammatory demyelinating polyneuropathy. Diagnosis of POEMS was established by an abnormal bone marrow biopsy, prompted by laboratory and imaging findings, which became abnormal later in the course of the disease. POEMS syndrome is extremely rare in children, and neuropathic features in this age group have not been previously described. This case illustrates that "Guillain-Barré syndrome-like" initial presentation for POEMS, which has not been previously reported. It also emphasizes that in children with progressive acquired neuropathies that are treatment unresponsive, POEMS syndrome should be considered.
