ABSTRACT

Background@#Pain is one of the most common chief complaints in neurological field. Authors try to inform the current situation of pain medicine in neurological practice and present an effective method for pain-related education during neurology residency and for practicing neurologists. @*Methods@#A survey was conducted from November 16 to November 27, 2020 for members of the Korean Neurological Association, and the results were analyzed. @*Results@#About two-thirds of neurologists replied that more than 25% of their patients were suffered from diverse pain including headache, spine pain or neuropathic pain. Despite many patients are visiting to neurologist for pain treatment, most neurologists are aware that they have not received sufficient practical pain education in the past and present. Therefore, they want more educational opportunities in pain medicine including interventional pain management and physical and pharmacologic therapies for more effective treatment. @*Conclusions@#More follow-up studies on pain treatment and education should be conducted. It is also essential that the members of the society continue to interest and participate in the change of the pain education program.

ABSTRACT

3) of the pain in domains of tingling/prickling sensation (p=0.024), mechanical allodynia (p=0.027), sudden pain attacks (p=0.018), and thermal hyperalgesia (p=0.002) were significantly more frequent in NMOSD compared to MS patients. Among the patients experiencing pain with a neuropathic component, total pain-related interference (p=0.045) scores were significantly higher in NMOSD patients than in MS patients. In daily life, pain interfered with normal work (p=0.045) and relationships with other people (p=0.039) more often in NMOSD patients than in MS patients. Although pain medication was prescribed more frequently in NMOSD patients, the percentage of patients experiencing medication-related pain relief was lower in those patients.CONCLUSIONS: The severity of neuropathic pain and the pain-related interference in daily life were greater in NMOSD patients than in MS patients. Individualized analgesic management should be considered based on a comprehensive understanding of neuropathic pain in these patients.

ABSTRACT

Background@#and Purpose: Previous studies suggest that cognitive intervention can mitigate the development of dementia in patients with mild cognitive impairment (MCI). However, the previous cognitive intervention was mostly provided as a group session, in which MCI patients sometimes had difficulty in regularly attending sessions or were reluctant to participate in group-based classes. Additionally, experienced instructors for traditional cognitive intervention may be unavailable in some chronic-care facilities or community centers. Considering these reasons, we have developed 5 programs for home-based cognitive intervention using a personal robot for MCI patients. In this preliminary study, we aimed to demonstrate the effects of our newly developed home-based cognitive intervention with robots on cognitive function in MCI patients. @*Methods@#We conducted a single-blind randomized controlled trial enrolling 46 MCI patients. Participants were randomized into 2 groups: the robot cognitive intervention (robot) (n=24) group and without cognitive intervention (control) (n=22) group. The interventions comprised 60-min sessions per day for 4 weeks. The primary outcome was the change in cognitive function measured using the Cambridge Neuropsychological Test Automated Battery. @*Results@#There were no significant baseline demographic or clinical differences between the robot and control groups. After the 4-week cognitive intervention, the robot group showed greater improvement in working memory than did the control group. @*Conclusions@#Our home-based cognitive intervention with a personal robot improved the working memory in MCI patients. Further studies with larger samples and longer study periods are required to demonstrate the effects of these programs in other cognitive domains in MCI patients.

ABSTRACT

In brain death state, bilateral pupil light reflexes are disappeared, and pupils are fixed with dilated. However, spontaneous movements such as ocular microtremor or bilateral cyclical constriction-dilatation of pupils have been rarely reported in brain death patients. We present a brain death patient whose right pupil displayed spontaneously repetitive constriction and dilatation regardless of external stimuli such as light and pain. Early recognition of this phenomenon may prohibit the delay in the diagnosis of brain death and organ transplantation.

ABSTRACT

Colchicine-induced neuromyopathy is an extremely rare complication, and can develop in the setting of acute overdose or chronic administration in therapeutic doses. A 72-year-old man presented with proximal muscle weakness and myalgia. He had angina pectoris and Behçet’s disease, leading to the treatment of colchicine (1.2 mg daily for about 6 years), cyclosporine, methylprednisolone, simvastatin, and aspirin. A biceps brachii muscle biopsy was performed and electron microscopic examination revealed scattered autophagic vacuoles. He was initially treated with steroid pulse therapy. However, muscle weakness did not improve. After the discontinuation of colchicine, muscle power and myalgia improved steadily. There should be heightened awareness of colchicine-induced neuromyopathy because that clinical suspicion is the most important diagnostic clue, and termination of colchicine is the only treatment.

ABSTRACT

Facioscapulohumeral muscular dystrophy type 1 (FSHD1) is caused by contraction of the D4Z4 repeat array. Recent studies revealed that the FAT1 expression is associated with disease activity of FSHD, and the FAT1 alterations result in myopathy with a FSHD-like phenotype. We describe a 59-year-old woman with both contracted D4Z4 repeat units and a FAT1 mutation. Shoulder girdle muscle weakness developed at the age of 56 years, and was followed by proximal leg weakness. When we examined her at 59 years of age, she displayed asymmetric and predominant weakness of facial and proximal muscles. Muscle biopsy showed increased variation in fiber size and multifocal degenerating fibers with lymphocytic infiltration. Southern blot analysis revealed 8 D4Z4 repeat units, and targeted sequencing of modifier genes demonstrated the c.10331 A>G variant in the FAT1 gene. This FAT1 variant has previously been reported as pathogenic variant in a patient with FSHD-like phenotype. Our study is the first report of a FAT1 mutation in a FSHD1 patient, and suggests that FAT1 alterations might work as a genetic modifier.

ABSTRACT

Orbital metastases are rare and predominantly unilateral occurrences. Bilateral metastases affecting the extraocular muscles are extremely rare. A few case reports of bilateral metastases to extraocular muscles described binocular diplopia with conspicuous bilateral external ophthalmoplegia as an initial symptom. We report a case in which unilateral ptosis was an initial symptom and bilateral incomplete ophthalmoplegia was found on initial neurologic examination in invasive ductal carcinoma of the breast. The patient had hormone receptor-positive breast cancer, and so was treated by hormonal therapies and closely monitored. The presence of a secondary orbital lesion presents many difficulties of differential diagnosis and treatment. A thorough neurologic examination to detect ocular manifestations is most important for localization and broad differential diagnosis including mechanical orbital metastatic lesion.

ABSTRACT

PURPOSE: This study was designed to investigate the characteristics of Korean patients with calpainopathy. MATERIALS AND METHODS: Thirteen patients from ten unrelated families were diagnosed with calpainopathy via direct or targeted sequencing of the CAPN3 gene. Clinical, mutational, and pathological spectra were then analyzed. RESULTS: Nine different mutations, including four novel mutations (NM_000070: c.1524+1G>T, c.1789_1790inA, c.2184+1G>T, and c.2384C>T) were identified. The median age at symptom onset was 22 (interquartile range: 15-28). Common clinical findings were joint contracture in nine patients, winged scapula in four, and lordosis in one. However, we also found highly variable clinical features including early onset joint contractures, asymptomatic hyperCKemia, and heterogeneous clinical severity in three members of the same family. Four of nine muscle specimens revealed lobulated fibers, but three showed normal skeletal muscle histology. CONCLUSION: We identified four novel CAPN3 mutations and demonstrated clinical and pathological heterogeneity in Korean patients with calpainopathy.

ABSTRACT

BACKGROUND AND PURPOSE: Acute myelitis patients exhibiting only sensory deficits upon initial presentation are not commonly encountered in clinical practice, but they definitely exist. Since acute sensory myelitis has not been investigated previously, this study evaluated the etiological spectrum of the condition with the aim of describing the clinical characteristics thereof. METHODS: Patients with acute myelitis who presented at the Ewha Womans University Medical Center (during 1999-2012) and the National Cancer Center (during 2005-2014) with only sensory symptoms as first clinical features were enrolled in this study. Their medical records, electrophysiological and laboratory data, and MRI findings were analyzed retrospectively. RESULTS: Of a total of 341 acute myelitis patients, 52 (15%) were identified as having acute sensory myelitis. The male-to-female ratio of these patients was 35:17, and their age at the onset of the condition was 41.7+/-10.5 years (mean+/-SD; range, 24-72 years). Acute sensory myelitis developed in patients with multiple sclerosis (MS; 14%), neuromyelitis optica spectrum disorder (NMOSD; 17%), and acute myelitis associated with concurrent systemic diseases including Behcet's disease and cancer (6%). Despite detailed evaluation, the etiology of 33 patients with acute myelitis could not be determined. Longitudinally extensive transverse myelitis on spinal MRI and progression of the sensory level were observed most commonly in NMOSD patients (89% and 78%, respectively); however, these patients did not exhibit sensory dissociation. Residual negative sensory symptoms were observed more frequently in NMOSD patients (33%) than in those with acute myelitis of unknown cause (24%) or MS (14%). During the long-term follow-up (4.7+/-2.7 years) of patients who did not undergo maintenance immunotherapy, a monophasic clinical course was common in those with acute myelitis of unknown cause (76%), but not in NMOSD or MS patients. CONCLUSIONS: Accurate identification of the diverse nature of acute sensory myelitis may assist in patient care.

ABSTRACT

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.

ABSTRACT

Vertebral artery dissection (VAD) is one of important causes of posterior circulation strokes in young age patients. Typical presentations of VAD are occipital headache or posterior neck pain, with various signs arising from brainstem or cerebellar infarctions. Muscular weakness or sensory change of an ipsilateral arm owing to cervical nerve root involvement in association with the VAD has been reported very rarely. Herein we describe two unusual manifestations of extracranial VAD, which presented with monoplegia of single upper limb.

ABSTRACT

Wegener's granulomatosis (WG) is a systemic vasculitis affecting small and medium-sized vessels with granulomatous formation. Though it is known for respiratory tract and kidney involvement, neurologic manifestation has been also reported. Herein we report a patient who suffered pansinusitis with multiple lower cranial nerve palsies but reached remission by immunosuppressant after the diagnosis of WG. A 54-yr-old female visited with headache, hearing difficulty, and progressive bulbar symptoms. She experienced endoscopic sinus surgeries due to refractory sinusitis. Neurologic examination revealed multiple lower cranial nerve palsies. Vasculitic markers showed no abnormality. Nasal biopsy revealed granulomatous inflammation and vasculitis involving small vessels. Given cyclophosphamide and prednisolone, her symptoms were prominently improved. WG should be considered in the patient with multiple cranial nerve palsies, especially those with paranasal sinus disease. Because WG can be lethal if delayed in treatment, prompt immunosuppressant is warranted after the diagnostic tissue biopsy.

ABSTRACT

BACKGROUND AND PURPOSE: X-linked bulbospinal muscular atrophy (X-BSMA) is characterized by bulbar and spinal muscular weakness and fasciculations. Although X-BSMA is a motor neuronopathy, there are several reports of myasthenic symptoms or decremental responses to repetitive nerve stimulation (RNS). We report the results of applying the RNS test to 15 patients among 41 with genetically confirmed X-BSMA; these 15 patients complained of fatigue, ease of becoming tired, or early muscular exhaustion. METHODS: The 3-Hz RNS test was performed on the trapezius, nasalis, orbicularis oculi, flexor carpi ulnaris, and abductor digiti quinti muscles. A decrement greater than 10% was considered abnormal. Additionally, a pharmacologic response to neostigmine was identified in three patients. RESULTS: A significant decrement was observed in 67% of patients, and was most common in the trapezius muscle (nine cases). The decrement of the trapezius muscle response ranged from 15.9% to 36.9%. The decrement was inversely correlated with the amplitude of compound muscle action potentials at rest. Neostigmine injection markedly improved the decrement in three patients, who showed noticeable decremental responses to 3-Hz RNS. CONCLUSIONS: This study shows that myasthenic symptoms and abnormal decremental responses to low-rate RNS are common in X-BSMA.
