Tracking psychosocial health in adults with epilepsy--estimates from the 2010 National Health Interview Survey.

OBJECTIVE: This study provides population-based estimates of psychosocial health among U.S. adults with epilepsy from the 2010 National Health Interview Survey. METHODS: Multinomial logistic regression was used to estimate the prevalence of the following measures of psychosocial health among adults with epilepsy and those without epilepsy: 1) the Kessler-6 scale of serious psychological distress; 2) cognitive limitation, the extent of impairments associated with psychological problems, and work limitation; 3) social participation; and 4) the Patient-Reported Outcome Measurement Information System Global Health Scale. RESULTS: Compared with adults without epilepsy, adults with epilepsy, especially those with active epilepsy, reported significantly worse psychological health, more cognitive impairment, difficulty in participating in some social activities, and reduced health-related quality of life (HRQOL). CONCLUSIONS: These disparities in psychosocial health in U.S. adults with epilepsy serve as baseline national estimates of their HRQOL, consistent with Healthy People 2020 national objectives on HRQOL.

Vecuronium-associated axonal motor neuropathy: a variant of critical illness polyneuropathy?

Neuromuscular blocking agents are routinely used as an adjunct therapy for critically ill patients. Unlike many neuromuscular blocking agents, vecuronium does not cause significant histamine release, which may lead to bronchoconstriction. Due to a short duration of action and limited accumulation, vecuronium has been widely used. Prolonged ventilatory dependence due to persistent neuromuscular blockade has been reported in patients treated with vecuronium. We report a case of an 8-year-old girl who had a primarily motor axonopathy presenting with weakness after extended vecuronium administration with prolonged course of recovery. This primarily motor neuropathy with axonal features may be a variant of critical illness polyneuropathy, a rarely reported condition in pediatric patients.

Light-induced amaurosis fugax.

PURPOSE: To describe an important symptom of bilateral amaurosis precipitated by exposure to bright light. METHODS: Case report. Clinical analysis of transient, painless, asymmetrical visual loss occurring in bright light in a 54-year-old man. RESULTS: Carotid ultrasound showed bilateral carotid disease. Carotid angiography demonstrated occlusion of the left internal carotid artery and severe stenosis of the right internal carotid artery and both external carotid arteries. Visual symptoms and an abnormal photostress test completely remitted after a right carotid endarterectomy. CONCLUSION: Light-induced amaurosis is an unfamiliar manifestation of ocular ischemic syndrome occurring with severe, often bilateral, carotid artery disease. Its recognition is important because the complaint is associated with severe carotid occlusive disease and recognition is necessary for timely surgical intervention because of the major risk for stroke.

Congenital cervical spinal atrophy: an intrauterine hypoxic insult.

We present two patients with congenital cervical spinal atrophy who were born at 37 and 33 weeks of gestation. Both patients were unrelated and had no family history of neuromuscular diseases. They presented at birth with arthrogryposis multiplex and symmetrical severe muscle weakness and wasting confined to the upper extremities. There was no sensory or bulbar symptom. Electromyography showed polyphasic and fast-firing units in the proximal muscles of the upper extremities. With the evidence of chronic denervation and re-innervation, we speculate that this static condition is most likely due to circulatory insufficiency causing anterior horn cell ischemia during the latter part of the first trimester.

Magnetic resonance and positron emission tomography changes during the clinical progression of Rasmussen encephalitis.

The authors describe serial positron emission tomography (PET) and magnetic resonance imaging (MRI) studies in a patient with pathologically confirmed Rasmussen Encephalitis (RE). Results of initial PET and MRI studies were normal. Subsequent studies showed involvement of the percentral and postcentral gyri and the putamen on PET, and the precentral and postcentral gyri on MRI. Coregistration of PET and MR images showed good correlation between the precentral and postcentral gyri involvement. However, subcortical involvement occurred earlier on PET than on MRI. The authors demonstrate the evolution of changes on PET and MR images in a patient with RE. Despite early pathologic confirmation of RE, there were no definite structural or functional imaging changes on PET or MRI until 3 years after symptom onset. These findings demonstrate the variability of imaging changes in RE, and the need to carefully correlate electro-physiologic and clinical findings to confirm the diagnosis of RE.
