| 1 | Neural Tract Degeneration Correlates with Functional Impairment in Patients with Anoxic Brain Injury:A Tract-based Spatial Statistics Study显示文摘Dear Editor,Anoxic brain injury(ABI)is a devastating event caused by cardiac arrest,chemical exposure,or trauma.Despite recent advances in medical diagnostic techniques and treatments,the survival rate after ABI is still very low.Previous studies have reported that 52.6%-64.0%of people who received cardiopulmonary resuscitation after nontraumatic cardiac arrest die,and 9.0%-18.6%remain in a permanent vegetative state within 28 days of treatment[1,2]. | Ji-Yun Park Sung Ho Park Jeong-Hee Yang Han Do Lee Jiho Lee Ki-Hyun Byeon Seo Young Park Dongseok Yang | 2020 | Neuroscience Bulletin2020，36，8： | 1 |
| 2 | Quantitative autonomic function test in differentiation of multiple system atrophy from idiopathic Parkinson disease显示文摘Background:Differential diagnosis of idiopathic Parkinson disease (IPD) and multiple system atrophy-Parkinson type (MSA-P) is challenging since they share clinical features with parkinsonism and autonomic dysfunction.To distinguish MSA-P from IPD when the symptoms are relatively mild,we investigated the usefulness of the quantitative fractionalized autonomic indexes and evaluated the correlations of autonomic test indexes and functional status.Methods:Thirty-six patients with parkinsonism (22 with IPD and 14 with MSA-P) in Soonchunhyang University Bucheon Hospital from February 2014 to June 2015 were prospectively enrolled in the study.We compared fractionalized autonomic indexes and composite autonomic scoring scale between patients with IPD and MSA-P with Hoehn and Yahr (H&Y) score ≤3.Parasympathetic indexes included expiratory/inspiratory ratio during deep breathing,Valsalva ratio (VR),and regression slope of systolic blood pressure (BP) in early phase Ⅱ (vagal baroreflex sensitivity) during Valsalva maneuver.Sympathetic adrenergic indexes were pressure recovery time (PRT) and adrenergic baroreflex sensitivity (BRSa) (BP decrement associated with phase 3 divided by the PRT),sympathetic index 1,sympathetic index 3,early phase Ⅱ mean BP drop,and pulse pressure reduction rate.Additionally,we compared the unified multiple system atrophy rating scale (UMSARS) and H&Y scores and the autonomic indexes in all patients.Results:PRT was significantly different between the IPD and MSA-P groups (P =0.004) despite the similar BP drop during tilt.Cutoff value of PRT was 5.5 s (sensitivity,71.4%;specificity,72.7%).VR (r =-0.455,P =0.009) and BRSa (r =-0.356,P =0.036) demonstrated a significant correlation with UMSARS and H&Y scores.Conclusions:Among the cardiovascular autonomic indexes,PRT can be a useful parameter in differentiating the early stage of MSA-P from that of IPD.Moreover,VR,and BRSa may be the optimal indexes in determining functional symptom severity. | Ji-Yun Park Dongseok Yang Hei-Jun Yang Hyun Ah Kim Saeromi Kim Deokhyun Heo Jeong-Ho Park Eek-Sung Lee Tae-Kyeong Lee | 2019 | Chinese Medical Journal2019，，16： | 1 |
| 3 | Association between scrub typhus encephalitis and diffusion tensor tractography detection of Papez circuit injury:A case report显示文摘BACKGROUND It is difficult to restore the cognitive functions of patients with impaired cognition caused by brain injury.Diffusion tensor imaging can visualize the integrity of neural tracts in the white matter(WM)three-dimensionally.It is unclear whether encephalitis following scrub typhus damages the WM.For the first time,we aimed to report diffusion tensor tractography(DTT)findings in a chronic patient with cognitive impairment following scrub typhus encephalitis,which revealed injury to the Papez circuit of the WM.CASE SUMMARY A 70-year-old male patient was affected by encephalitis caused by scrub typhus that occurred 23 years ago.He had poor cognition and his clinical examination findings were as follows:Mini-Mental Status Examination score,14;and handgrip strength(right/left,kg),32.3/31.3.DTT revealed serious injuries of the left thalamocingulate tract and right mammillothalamic tract in the Papez circuit,and a partial injury of the anterior part of the fornix.CONCLUSION Using DTT,we found a relationship between cognitive impairment and the integrity of the Papez circuit following scrub typhus. | Hyeok Gyu Kwon Jeong-Hee Yang Jee-Hyun Kwon Dongseok Yang | 2021 | World Journal of Clinical Cases2021，9，13： | 0 |
