Proportion and Reasons for Ineligibility to Re-register for Extended Health Insurance in Neovascular Age-related Macular Degeneration

Purpose@#To evaluate the proportion and reasons for ineligibility to re-register for extended health insurance at 5 years in patients diagnosed with neovascular age-related macular degeneration (AMD) and registered for extended health insurance. @*Methods@#This retrospective study was performed in patients diagnosed with neovascular AMD and registered for extended health insurance with follow-up for at least 5 years. The criteria for re-registration for extended health insurance were determined along with the ineligibility for re-registration. @*Results@#In total, 263 patients were included in the analysis. Of these, 148 (56.3%) did not satisfy the criteria for re-registration. No active treatment was performed in 98 patients during the last 6 months of the study period (no recurrence, 51 patients; additional treatment was not considered beneficial due to retinal damage even without disciform scar formation, 44 patients). Macular disciform scar formation was noted in 50 patients (33.8%). Older age (p = 0.013), poor visual acuity (p = 0.004), and retinal angiomatous proliferation (p < 0.001) were associated with ineligibility for re-registration due to severe retinal damage. @*Conclusions@#Among the patients who were initially registered for extended health insurance, 56.3% failed to satisfy the re-registration criteria. The primary reason was advanced retinal damage. The results of this study provide useful information for patient education and to establish long-term treatment strategies.

Proportion of and Reason for Bevacizumab Usage in the Treatment of Wet Age-related Macular Degeneration

Purpose@#To evaluate the proportion of bevacizumab and the reason for its usage in wet age-related macular degeneration (AMD). @*Methods@#Retrospective analysis of medical records was performed for 1,541 patients who received ranibizumab, aflibercept, or bevacizumab injection to treat wet AMD. The proportion of bevacizumab among the entire set of injections was identified. The reason for selecting bevacizumab was additionally identified. @*Results@#During the study period, a total of 2,929 anti-vascular endothelial growth factor (anti-VEGF) injections were performed; 2,236 (76.3%) were ranibizumab or aflibercept injections and 693 (23.7%) were bevacizumab injections. The most common reason for bevacizumab usage was ‘having a 0.1 or worse best-corrected visual acuity or being unable to assure reimbursement due to the development of extensive scarring or geographic atrophy’ (297 bevacizumab injections, 42.9%). The second most common reason was ‘the inability to assure reimbursement such as extrafoveal choroidal neovascularization (CNV) or early CNV without definite fluid in the foveal region’ (201 bevacizumab injections, 29.0%). @*Conclusions@#Bevacizumab was used in 23.7% of the anti-VEGF injections to treat wet AMD. When analyzing patients’ treatment burden and financial impact, the results of the present study may provide useful information. Further multi-center studies are required to evaluate more precisely the usage of anti-VEGF drugs.

Validation of the Korean Version of the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease Rating Scale

Background@#and PurposeImpulse-control disorder is an important nonmotor symptom of Parkinson's disease (PD) that can lead to financial and social problems, and be related to a poor quality of life. A nationwide multicenter prospective study was performed with the aim of validating the Korean Version of the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease Rating Scale (K-QUIP-RS). @*Methods@#The K-QUIP-RS was constructed using forward and backward translation, and pretesting of the prefinal version. PD patients on stable medical condition were recruited from 27 movement-disorder clinics. Participants were assessed using the K-QUIP-RS and evaluated for parkinsonian motor and nonmotor statuses and for PD-related quality of life using a predefined evaluation battery. The test–retest reliability of the K-QUIP-RS was assessed over an interval of 10–14 days, and correlations between the KQUIP-RS and other clinical scales were analyzed. @*Results@#This study enrolled 136 patients. The internal consistency of the K-QUIP-RS was indicated by a Cronbach's α coefficient of 0.846, as was the test–retest reliability by a Guttman split-half coefficient of 0.808. The total K-QUIP-RS score was positively correlated with the scores for depression and motivation items on the Unified PD Rating Scale (UPDRS), Montgomery-Asberg Depression Scale, and Rapid-Eye-Movement Sleep-Behavior-Disorders Questionnaire. The total K-QUIP-RS score was also correlated with the scores on part II of the UPDRS and the PD Quality of Life-39 questionnaire, and the dopaminergic medication dose. @*Conclusions@#The K-QUIP-RS appears to be a reliable assessment tool for impulse-control and related behavioral disturbances in the Korean PD population.

Subtypes of Sleep Disturbance in Parkinson's Disease Based on the Cross-Culturally Validated Korean Version of Parkinson's Disease Sleep Scale-2

Anti-N-methyl-D-aspartate Receptor Encephalitis after Herpes Simplex Virus Infection

Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis has clinical features of psychiatric symptoms, loss of memory, seizure, dyskinesia and autonomic dysfunction. While Anti-NMDA receptor encephalitis was initially reported in young women with ovarian teratoma, viral infections can trigger anti-NMDA receptor encephalitis as well. Among them, herpes virus is the most common. We report a patient who developed the anti-NMDA receptor encephalitis 47 days after herpes virus encephalitis, which is, to our knowledge, the first case in Korea.

Validation of the Korean Version of the Scales for Outcomes in Parkinson's Disease-Sleep

BACKGROUND: Sleep problems commonly occur in patients with Parkinson's disease (PD), and are associated with a lower quality of life. The aim of the current study was to translate the English version of the Scales for Outcomes in Parkinson's Disease-Sleep (SCOPA-S) into the Korean version of SCOPA-S (K-SCOPA-S), and to evaluate its reliability and validity for use by Korean-speaking patients with PD. METHODS: In total, 136 patients with PD from 27 movement disorder centres of university-affiliated hospitals in Korea were enrolled in this study. They were assessed using SCOPA, Hoehn and Yahr Scale (HYS), Unified Parkinson's Disease Rating Scale (UPDRS), Parkinson's Disease Sleep Scale 2nd version (PDSS-2), Non-motor Symptoms Scale (NMSS), Montgomery Asberg Depression Scale (MADS), 39-item Parkinson's Disease Questionnaire (PDQ39), Neurogenic Orthostatic Hypotension Questionnaire (NOHQ), and Rapid Eye Movement Sleep Behaviour Disorder Questionnaire (RBDQ). The test-retest reliability was assessed over a time interval of 10–14 days. RESULTS: The internal consistency (Cronbach's α-coefficients) of K-SCOPA-S was 0.88 for nighttime sleep (NS) and 0.75 for daytime sleepiness (DS). Test-retest reliability was 0.88 and 0.85 for the NS and DS, respectively. There was a moderate correlation between the NS sub-score and PDSS-2 total score. The NS and DS sub-scores of K-SCOPA-S were correlated with motor scale such as HYS, and non-motor scales such as UPDRS I, UPDRS II, MADS, NMSS, PDQ39, and NOHQ while the DS sub-score was with RBDQ. CONCLUSION: The K-SCOPA-S exhibited good reliability and validity for the assessment of sleep problems in the Korean patients with PD.

Spontaneous Thrombosis of Posterior Inferior Cerebellar Artery Aneurysm Presenting as Cerebellar Infarction

Ischemic stroke caused by spontaneous thrombosis of posterior inferior cerebellar artery (PICA) aneurysm has been rarely reported. A 52-year-old man presented with sudden headache, dizziness, and gait disturbance. Diffusion-weighted MRI showed acute infarction in left PICA territory. A saccular aneurysm with internal thrombus at the distal PICA was detected by CT angiography and conventional angiography. The thrombus resolved spontaneously at 2 months after stroke onset with aspirin medication. At that time, endovascular coiling was underwent successfully to prevent aneurysmal rupture.

Validation of the Korean Version of the Scale for Outcomes in Parkinson's Disease-Autonomic

OBJECTIVE: Autonomic symptoms are commonly observed in patients with Parkinson's disease (PD) and often limit the activities of daily living. The Scale for Outcomes in Parkinson's disease-Autonomic (SCOPA-AUT) was developed to evaluate and quantify autonomic symptoms in PD. The goal of this study was to translate the original SCOPA-AUT, which was written in English, into Korean and to evaluate its reliability and validity for Korean PD patients. METHODS: For the translation, the following processes were performed: forward translation, backward translation, expert review, pretest of the pre-final version and development of the final Korean version of SCOPA-AUT (K-SCOPA-AUT). In total, 127 patients with PD from 31 movement disorder clinics of university-affiliated hospitals in Korea were enrolled in this study. All patients were assessed using the K-SCOPA-AUT and other motor, non-motor, and quality of life scores. Test-retest reliability for the K-SCOPA-AUT was assessed over a time interval of 10−14 days. RESULTS: The internal consistency and reliability of the K-SCOPA-AUT was 0.727 as measured by the mean Cronbach's α-coefficient. The test-retest correlation reliability was 0.859 by the Guttman split-half coefficient. The total K-SCOPA-AUT score showed a positive correlation with other non-motor symptoms [the Korean version of non-motor symptom scale (K-NMSS)], activities of daily living (Unified Parkinson's Disease Rating Scale part II) and quality of life [the Korean version of Parkinson's Disease Quality of Life 39 (K-PDQ39)]. CONCLUSION: The K-SCOPA-AUT had good reliability and validity for the assessment of autonomic dysfunction in Korean PD patients. Autonomic symptom severities were associated with many other motor and non-motor impairments and influenced quality of life.

Severe Right Internal Carotid Artery Stenosis Mimicking Behavioral Variant Frontotemporal Dementia

Many kinds of degenerative, psychiatric, and cerebrovascular diseases can mimic behavioral variant frontotemporal dementia. We present a 73-year-old woman who presented with apathy, inappropriate social behavior, and persecutory delusion. A neuropsychological examination revealed frontal/executive dysfunction with relative sparing of episodic memory. Magnetic resonance imaging and F-18 fluorodeoxyglucose positron-emission tomography produced normal findings. However, magnetic resonance angiography revealed severe right internal carotid stenosis. After carotid stenting, her behavioral symptoms disappeared and did not recur during an 18-month follow-up.

Multiple Cerebral Infarctions with Neurological Symptoms and Ophthalmic Artery Occlusion after Filler Injection

PURPOSE: To report a case of visual loss, side weakness and facial palsy due to ophthalmic artery occlusion with diffuse multiple cerebral infarctions after injection of hyaluronic acid. CASE SUMMARY: A 50-year-old female visited our clinic for visual loss in the left eye after filler injection in the glabella. Her best corrected visual acuity was 1.0 in the right eye and hand motion in the left eye. The intraocular pressure was 8 mm Hg in the right eye and 14 mm Hg in the left eye. In the left eye, there was abnormal pupillary light reflex and complete extra-ocular muscles palsy with blepharoptosis. A pale retina with a cherry-red-spot also appeared in the left fundus. A central retinal artery occlusion was observed on fluorescein angiography and brain magnetic resonance imaging showed multiple cerebral infarctions at the frontal, temporal, parietal and occipital lobes. Four days later, the motor weakness was aggravated and dysarthria and aphasia became worse. According to symptoms, a hemorrhagic transformation in subacute infarctions developed based on brain computed tomography. After 3 months of follow up, the visual acuity in the left eye was no light perception. However, the general conditions including ophthalmoplegia and motor weakness were improved.

The Usefulness of Proximal Radial Motor Conduction in Acute Compressive Radial Neuropathy

BACKGROUND AND PURPOSE: The objective of this study was to determine diagnostic and prognostic values of proximal radial motor conduction in acute compressive radial neuropathy. METHODS: Thirty-nine consecutive cases of acute compressive radial neuropathy with radial conduction studies-including stimulation at Erb's point-performed within 14 days from clinical onset were reviewed. The radial conduction data of 39 control subjects were used as reference data. RESULTS: Thirty-one men and eight women (age, 45.2+/-12.7 years, mean+/-SD) were enrolled. All 33 patients in whom clinical follow-up data were available experienced complete recovery, with a recovery time of 46.8+/-34.3 days. Partial conduction block was found frequently (17 patients) on radial conduction studies. The decrease in the compound muscle action potential area between the arm and Erb's point was an independent predictor for recovery time. CONCLUSIONS: Proximal radial motor conduction appears to be a useful method for the early detection and prediction of prognosis of acute compressive radial neuropathy.

Use of Fundus Autofluorescence Images to Evaluate the Progression of Geographic Atrophy: Two-Year Follow-Up Study

PURPOSE: We evaluated the progression of geographic atrophy (GA) based on fundus autofluorescence (FAF) pattern and atrophy size using the fundus camera in non-exudative age-related macular degeneration (ARMD). METHODS: We acquired FAF images in non-exudative ARMD patients over a 2-year period. According to The Fundus Autofluorescence in Age-related Macular Degeneration (FAM) study, FAF patterns of geographic atrophy were classified into 5 categories. Examiners quantified the areas of GA in FAF images and analyzed the progression of atrophy based on FAF pattern and atrophy size. RESULTS: In 86 non-exudative ARMD eyes, elderly patients had faster progression rate of GA. The growth rates of GA were 1.51 mm2/year in 'Diffuse', 1.49 mm2/year in 'Banded', 1.05 mm2/year in 'Patchy', 0.59 mm2/year in 'Focal' and 0.16 mm2/year in 'None' pattern groups. In addition, the growth rate was 0.38 mm2/year in which initial the GA area was smaller than 1 disc area. This was the slowest progression rate among all categories according to initial GA area. CONCLUSIONS: As a result of evaluating the progression of geographic atrophy using FAF over a 2-year period, the growth rate of GA was the fastest in the 'Diffuse' pattern group. Additionally, as the initial GA area became smaller, the progression of GA atrophy was slower (p < 0.002). Although limitations such as short follow-up period and measurement error of GA atrophy area using fundus photography were compensated, the results in the present study were similar to the outcomes of studies on progression of GA based on FAF pattern using the scanning laser ophthalmoscope over several years and the fundus camera for 1 year. In conclusion, the fundus camera is a useful tool for the prediction of long-term progression of GA in patients with non-exudative ARMD.

A Case of Serous Macular Detachment Preceding Macular Retinoschisis in an Optic Pit

PURPOSE: To report a case of serous macular detachment preceding macular retinoschisis in an optic pit patient successfully treated by vitrectomy with internal limiting membrane peeling. CASE SUMMARY: A 76 year old female visited our clinic for visual disturbance in her right eye. Fundus photograph revealed optic pit and OCT showed macular retinoschisis in her right eye. She was followed up in our clinic. The patient revisited our clinic because of sudden decrease of visual acuity in her right eye 3 days before. At that time, the patient's best-corrected visual acuity was 0.05. Macular retinoschisis, subretinal fluid and serous retinal detachment were observed in her right eye on OCT. She was diagnosed with serous retinal detachment associated with optic pit and pars plana vitrectomy was performed. During vitrectomy, we found adhesion and defect of posterior hyaloid membrane which covered the optic pit. Therefore, subretinal fluid was drained via membrane defect and posterior vitreous detachment and fluid-gas exchange were induced. Sixteen days after surgery, we found a macular hole in her right eye on OCT. Pars plana vitrectomy was performed with internal limiting membrane peeling. One month after surgery, macular detachment was not observed. Six months after surgery, the patient's best corrected visual acuity was 0.63 and the macula was reattached completely. CONCLUSIONS: Optic pit maculopathy can be progressed rapidly in aged patients and macular hole would be ocurred as a complication. Additional study will be needed to figure out the role of internal limiting membrane and tractional force of posterior vitreous in these patients.

Clinical Analysis of Blepharospasm and Apraxia of Eyelid Opening in Patients with Parkinsonism

BACKGROUND AND PURPOSE: Blepharospasm (BSP) and apraxia of eyelid opening (AEO) have been reported as dystonia related with parkinsonism. However, systematic analysis of clinical characteristics of BSP and AEO in parkinsonism has been seldom reported. To investigate the clinical characteristics of BSP and AEO in parkinsonism and to find out the clinical significance to differentiate parkinsonism. METHODS: We enrolled 35 patients who had BSP with or without AEO out of 1113 patients with parkinsonism (913 IPD, idiopathic Parkinson's disease; 190 MSA, multiple system atrophy, 134 MSA-p, 56 MSA-c and 10 PSP, progressive supranuclear palsy). We subdivided MSA into MSA-p (predominantly parkinsonism) and MSA-c (predominantly cerebellar) according to the diagnostic criteria proposed by Quinn. We analyzed the clinical features of BSP and parkinsonism including onset age, onset interval to BSP, characteristics of BSP, presence of AEO, coexisted dystonias on the other body parts, severity of parkinsonism and relationship with levodopa treatment. RESULTS: BSP with or without AEO were more frequently observed in atypical parkinsonism (PSP, 70%; MSA-p, 11.2%; MSA-c, 8.9%) than in IPD (0.9%). Reflex BSP was observed only in atypical parkinsonism (4 MSA-p, 1 MSA-c and 2 PSP). BSP preceding parkinsonism (Pre-BSP) was observed mainly in atypical parkinsonism (2 MSA-p, 1 MSA-c, 1 PSP and 1 IPD). The presence of AEO was more frequent in atypical parkinsonism than in IPD, but isolated AEO was not detected. BSP related to levodopa ('off' symptom or 'peak-dose' effect) were observed only in IPD. CONCLUSIONS: Reflex BSP, Pre-BSP and the presence of AEO may be a unique feature of atypical parkinsonism. BSP related to levodopa might be representative of IPD. No differences were found in the clinical features of BSP between MSA-p and MSA-c.

Acute Painful Sensory Neuropathy Diagnosed as Nonsystemic Vasculitic Neuropathy

Nonsystemic vasculitic neuropathy (NSVN) is a localized vasculitis confined to the peripheral nerves. Absence of systemic manifestations frequently leads to mis- or under diagnosis without the aid of pathologic study. NSVN may present typically with multiple mononeuropathies or less commonly with a sensorimotor polyneuropathy. We report two cases of NSVN presenting with acute severe painful neuropathy. Sural nerve pathology showed unequivocal vasculitis. High dose corticosteroid therapy was effective in controlling the pain. NSVN should be considered as a treatable cause of acute painful neuropathy.
