RESUMO
Background@#and Purpose The Individualized Neuromuscular Quality of Life questionnaire (INQoL) is a widely used measure of the quality of life in patients with neuromuscular diseases. The purpose of this study was to translate and validate the Korean version of INQoL in Korean patients with neuromuscular diseases. @*Methods@#We translated the original INQoL version into Korean while applying appropriate language adaptations. The internal consistency, known-group validity, and test-retest reliability were also assessed. Construct validity was measured using the modified Rankin Scale (mRS) score and the manual muscle testing (MMT)-sum score based on the Medical Research Council scale, and concurrent validity was measured using the 36-item Short Form Survey (SF-36) questionnaire. @*Results@#This study enrolled 193 patients. The coefficients for internal consistency (Cronbach’s α=0.805 to 0.987) and test-retest reliability (Spearman’s ρ=0.453 to 0.886) were adequately high for all subscales except in the ‘treatment effects’ dimension. INQoL subscales other than those for locking, droopy eyelids, double vision, and swallowing difficulties were significantly associated with their relevant SF-36 domains (Spearman’s ρ=-0.274 to -0.833). Functional status and muscle strength were most strongly associated with independence (Spearman’s ρ=0.753 and p<0.001 for mRS score, Spearman’s ρ=-0.741 and p<0.001 for MMT-sum score). @*Conclusions@#The Korean INQoL is a reliable and validated measurement tool for Korean patients with neuromuscular diseases.
RESUMO
Extrapontine myelinolysis is a demyelinating disorder usually caused by rapid correction of chronic hyponatremia. We present an 82-year-old female patient with general weakness, and severe hyponatremia (103 mEq/L) which was corrected 14 mEq/L during 21 hours. She was stuporous and presented status epilepticus. Brain T2-weighted image showed high signal intensities of bilateral thalami and electroencephalogram monitoring indicated right hemisphere lateralized periodic discharges, maximal in the right frontal region. This case shows that status epilepticus can occur in a patient of extrapontine myelinolysis involved bilateral thalami without pontine lesions.

Ischemic stroke caused by the cerebral vasculopathy is a rare complication of polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. We present a case of recurrent ischemic strokes caused by cerebral vasculopathy in a patient with POEMS syndrome. A 34-year-old man presented with gait disturbance and dizziness. Brain magnetic resonance imaging demonstrated acute ischemic stroke in the middle cerebral artery-anterior cerebral artery (MCA-ACA) border zones of bilateral hemispheres. Repeated angiographic studies showed progressive worsening of the left distal internal carotid artery, ACA, and MCA stenoses, along with sustained steno-occlusion of right MCA.
