        척수 뒤기둥을 침범한 간성 척수병증

        주병억,김병조,박건우,이대희,김호정 대한신경과학회 2008 대한신경과학회지 Vol.26 No.2

        Hepatic myelopathy is a rare neurological complication of chronic liver disease, and is characterized by a progressing spastic paraparesis without any sensory loss. However, a few recent reports suggest that involvement of the sensory system is also possible in hepatic myelopathy. We present a patient with hepatic myelopathy, who had impaired proprioception and a delayed cortical response of somatosensory evoked potentials. This supports the hypothesis that hepatic myelopathy may involve the sensory system as well as the motor system.

        Advances in Intraoperative Neurophysiology During Microvascular Decompression Surgery for Hemifacial Spasm

        주병억,김준순,Vedran Deletis,박경석 대한신경과학회 2022 Journal of Clinical Neurology Vol.18 No.4

        Microvascular decompression (MVD) is a widely used surgical intervention to relieve the abnormal compression of a facial nerve caused by an artery or vein that results in hemifacial spasm (HFS). Various intraoperative neurophysiologic monitoring (ION) and mapping methodologies have been used since the 1980s, including brainstem auditory evoked potentials, lateral-spread responses, Z-L responses, facial corticobulbar motor evoked potentials, and blink reflexes. These methods have been applied to detect neuronal damage, to optimize the successful decompression of a facial nerve, to predict clinical outcomes, and to identify changes in the excitability of a facial nerve and its nucleus during MVD. This has resulted in multiple studies continuously investigating the clinical application of ION during MVD in patients with HFS. In this study we aimed to review the specific advances in methodologies and clinical research related to ION techniques used in MVD surgery for HFS over the last decade. These advances have enabled clinicians to improve the efficacy and surgical outcomes of MVD, and they provide deeper insight into the pathophysiology of the disease

        반쪽얼굴연축에 대한 미세혈관감압술에서의 수술 중 신경계 감시

        주병억 대한근전도전기진단의학회 2020 대한근전도 전기진단의학회지 Vol.22 No.1

        Hemifacial spasm (HFS) is due to the vascular compression of the facial nerve at its root exit zone (REZ). Microvascular decompression (MVD) of the facial nerve near the REZ is an effective and curative treatment for HFS. In MVD for HFS, intraoperative neurophysiological monitoring (IONM) has two purposes. The first purpose is to prevent injury to neural structures such as the vestibulocochlear nerve and facial nerve during MVD surgery, which is possible through IONM of brainstem auditory evoked potentials and facial nerve electromyography (EMG). The second purpose is the unique feature of MVD for HFS, which is to assess and optimize the effectiveness of the vascular decompression. The purpose is achieved mainly through monitoring of abnormal facial nerve EMG that is called as lateral spread response (LSR) and is also partially possible through Z-L response, facial F-wave, and facial motor evoked potentials. Through IONM mentioned above, MVD can be developed as a more safe and effective treatment for HFS.

        노인장기요양보험서비스의 현황 및 나아갈 방향: 설문조사 및 국민 건강보험서비스 자료

        송은향,문연실,박정현,주병억,한호성,이찬녕,한현정,김재문 대한신경과학회 2024 대한신경과학회지 Vol.42 No.1

        The continuing growth of population aged 65 years and above, the socioeconomic burden of long-term care insurance has consistently increased. This study aimed to review the current system and efficiently develop long-term care insurance services according to changes in socioeconomic situations. First, a 21 items questionnaire survey was conducted from August 16 to August 31, 2022, for all members of the Korean Neurological Association. The survey was divided into seven areas, and individualized results were analyzed. Second, cumulative data on long-term care insurance services were collected and analyzed from July 1, 2008 to December 31, 2021, for the National Health Insurance system, and the results were summarized. In the survey, approximately 21% of the neurologists answered a web-based questionnaire survey on current doctors’ referral slips for long-term insurance services. Most (94%) had doctor referral slips for long-term insurance services. However, the authors estimated that doctors’ referral slips did not sufficiently affect the grading of longterm insurance services. The long-term care insurance services data according to several categories were classified and then, we statistically analyzed the socioeconomic burden of long-term insurance. Those cumulative data showed a gradual increase in the recipient number, diversity of geriatric diseases, and socioeconomic burden. We suggested that it is necessary for the government and academic society to continue to cooperate to develop the long-term care insurance systems for elderly.

        비디오 안진 검사를 이용한 렘수면행동장애의 뇌줄기 기능 저하에 대한 연구

        김영헌,박정호,추승호,조현진,서대원,주병억,주은연 대한신경과학회 2023 대한신경과학회지 Vol.41 No.4

        Background: This study aimed to differentiate video nystagmography (VNG) characteristics, including the video head impulse test (vHIT), in patients with idiopathic rapid eye movement behavior disorder (RBD) from healthy controls, which is considered a precursor to degenerative diseases. Methods: One hundred eighty-five patients underwent overnight polysomnography (PSG) and VNG. Based on overnight PSG, 27 patients with RBD or REM sleep without atonia (RWA) and AHI<15 were categorized into the RBD group, 34 patients with RBD/RWA and AHI≥15 were grouped into the combined group. Sixty patients with AHI≥15 and no RBD/RWA were included in the obstructive sleep apnea (OSA) group, and 64 negative participants were assigned to the control group. In VNG, we measured the gain of vHIT in each canal, with the latency, amplitude, and velocity of horizontal saccades and smooth pursuit. We compared the results between groups using ANOVA, after normalization and adjustment for age and sex. Results: The gain of vHIT in the left horizontal canal was decreased in the RBD group, but it was more pronounced in the OSA group. Elevated gain of the left posterior canal was seen in the RBD group, but technical errors were attributable. The RBD group displayed prolonged latency of saccade on the left side and slowed saccade on the right side, but these were statistically insignificant. Conclusions: The VNG study revealed differences between the sleep disorders, potentially reflecting brainstem function in each disorder. However, these differences lacked statistical significance. We anticipate that significant results could be obtained with more controlled conditions.
