Authors have experienced a case of retinal occlusion in patient with mitral valve prolapse. The patient was 10-year-old male who had visited our hospital due to the sudden onset of painless diminished vision and visual field defect of right eye since 2 days ago. The funduscopic finding of right eye showed typical appearance of retinal arterial occlusion with ischemic retinal whitening which app3ared as opacification. And, we also found mitral valve prolapse in this patient. One of the recently reported complications of mitral valve prolapse is thromboemboli resulting in cerebral ischemic events and visual complications. Such emboli can explain some cases of branch and central retinal arterial occlusion.

BACKGROUND: The decreased estimated glomerular filtration rate (eGFR) levels at admission in patients with stroke have been associated with more severe clinical deficits and with worse outcomes; however, the relationship between eGFR levels and volumetric measurement of cerebral infarct size on neuroimaging has not been studied, to our knowledge. METHODS: Consecutive patients who presented within 48h of ischemic stroke and underwent brain diffusion-weighted imaging (DWI) over a 55-month period were studied. Patients with ischemic stroke of large artery atherosclerosis (LAA), small vessel occlusion (SVO), or cardioembolism (CE) etiologies were included. Those who were treated with thrombolysis and disabled before index stroke were excluded. Infarction volumes were log transformed to approximate normality. Chronic kidney disease (CKD) was defined as an eGFR < 60 mL/min per 1.73 m2. Subjects were categorized into two groups: CKD or no CKD. The relationship between CKD and DWI infarct volumes was examined using an analysis of covariance. RESULTS: Of the included 405 patients (mean age, 68 years; female, 60.2%; LAA, 60.0%; SVO, 16.5%; CE, 23.5%), 108 patients had CKD. Infarct volumes (mL, median [interquartile range]) were not significantly different between stroke patients with CKD and those without CKD in any stroke subtype (LAA, 0.77 [0.01-2.97] vs. 0.96 [0.01-5.22]; SVO, 0.18 [0.02-0.21] vs. 0.27 [0.01-0.52]; CE, 8.91 [0.04-28.54] vs. 5.22 [0.05-42.39]). Adjustment for possible confounders did not change the associations. CONCLUSIONS: Renal impairment is not associated with cerebral infarct volume among acute ischemic stroke patients.

PURPOSE: Psychometric properties of the overactive bladder questionnaire (OAB-q) were recently examined. However, since the cross-cultural adaptation of a non-English version of the OAB-q has never been demonstrated, we evaluated the psychometric properties of a Korean version of the OAB-q in a Korean population with OAB. METHODS: A prospective cohort study involving 116 women with 58 OAB and 58 control subjects was performed and convergent validity was assessed. Total and subscale OAB-q scores of the control and OAB groups were compared to their sensitivity to score changes before and after administering anti-cholinergic medication for 12 weeks. Short form 36 and King's health questionnaire (KHQ) were also used for comparison or correlation. RESULTS: Assessment of face validity showed that the Korean version of the OAB-q was reasonable with OAB-q subscale scores being significantly different between the control and patient groups. Significant correlation (range, -0.29 to -0.81) was found between the OAB-q scores and KHQ results for the OAB patients. Cronbach's alpha coefficients (range, 0.77 to 0.95) indicated excellent internal consistency and test-retest analysis involving 35 OAB patients showed that each questions as well as subscale scores were reproducible. Each score of OAB-q also showed statistically significant sensitivity to changes following anti-muscarinic treatment for OAB (n=27, P<0.001 except for social, P=0.059). CONCLUSIONS: The Korean version of the OAB-q is a valid and reliable instrument to measure outcomes in Korean patients with OAB.
