Abstract
OBJECTIVES:People with cerebellar ataxia have few options to improve the standing stability they need for function. Strategic placement of light weights on the torso using the balance-based torso-weighting (BBTW) method has improved stability and reduced falls in people with multiple sclerosis, but has not been tested in cerebellar ataxia. We examined whether torso-weighting increased standing stability and/or functional movement in people with cerebellar ataxia. METHODS:Ten people with cerebellar ataxia and 10 matched controls participated in this single-session quasi-experimental pilot study. People with ataxia performed the Scale for the Assessment and Rating of Ataxia (SARA) prior to clinical testing. All participants donned inertial sensors that recorded postural sway; stopwatches recorded duration for standing and mobility tasks. All participants stood for up to 30 s on firm and foam surfaces with eyes open then eyes closed, and performed the Timed Up and Go (TUG) test. Light weights (0.57-1.25 kg) were strategically applied to a vest-like garment. Paired t tests compared within-group differences with and without BBTW weights. Independent t tests assessed differences from controls. All t tests were one-tailed with alpha set at .05. RESULTS:Duration of standing for people with ataxia was significantly longer with weighting (p = .004); all controls stood for the maximum time of 120 s with and without weights. More severe ataxia according to SARA was moderately correlated with greater improvement in standing duration with BBTW (Pearson r = .54). Tasks with more sensory challenges (eyes closed, standing on firm surface) showed less body sway with weighting. Duration for the TUG was unchanged by torso-weighting in people with ataxia. CONCLUSION:Strategic weighting improved standing stability but not movement speed in people with ataxia. BBTW has potential for improving stability and response to challenging sensory conditions in this population. Future studies should further examine gait stability measures along with movement speed.
摘要
目的: 小脑共济失调患者几乎没有改善其功能所需的站立稳定性的选择。使用基于平衡的躯干加权 (BBTW) 方法在躯干上战略性地放置轻质重量,提高了多发性硬化症患者的稳定性,减少了跌倒,但尚未在小脑共济失调中进行测试。我们检测了躯干加权是否增加小脑性共济失调患者的站立稳定性和/或功能运动。 方法: 10 名小脑性共济失调患者和 10 名匹配的对照者参与了这项单环节准实验初步研究。共济失调患者在临床检测前进行了共济失调评估和评级量表 (SARA)。所有参与者都戴上记录姿势摇摆的惯性传感器; 秒表记录站立和移动任务的持续时间。所有参与者在紧实和泡沫表面睁眼然后闭眼站立长达 30 s,并进行计时上升走 (TUG) 测试。轻质 (0.57-1.25千克) 战略性地应用于背心状服装。配对t检验比较了伴和不伴BBTW重量的组内差异。独立t检验评估与对照组的差异。所有t检验均为单尾检验,α 设为.05。 结果: 加权后,共济失调患者的站立持续时间显著延长 (p = .004); 所有对照者的最大站立时间为 120 s,有体重和无体重。根据SARA,更严重的共济失调与BBTW的站立持续时间改善程度中度相关 (Pearson r = .54)。感觉挑战较多的任务 (闭眼,站在坚固的表面上) 显示出较少的体重身体摇摆。通过对共济失调患者的躯干加权,TUG的持续时间不变。 结论: 策略性加权改善了共济失调患者的站立稳定性,但改善了运动速度。BBTW具有改善该人群稳定性和对挑战性感觉条件反应的潜力。未来的研究应进一步检查步态稳定性指标以及运动速度。

METHODS::Purpose: To report on ocular Vogt-Koyanagi-Harada (VKH)-like syndrome under vemurafenib treatment for metastatic melanoma.Design: A case report.Method: Description of clinical and imaging manifestations including fundus photography, fluorescein, and indocyanine green angiography.Results: A 46-year-old Thai female was diagnosed with metastatic melanoma of the skin and had been treated with multiple surgical excisions, radiotherapy, and vemurafenib (initial dose 480 mg orally twice daily, subsequently increased to maximum dose of 960 mg twice daily). After 6 months of vemurafenib use, she complained of bilateral redness and photophobia and was diagnosed with bilateral anterior uveitis, which was topically treated. Two weeks later, her visual acuity (VA) sharply deteriorated to 20/80 and counting fingers. Ocular examination at that stage stronly resembled acute VKH disease. She exhibited intraocular inflammation, and her fundus examination revealed bilateral optic disc swelling and serous retinal detachment. Fluorescein angiogram showed disc leakage and multiple pinpoint hyperfluorescence leakage spots and indocyanine green demonstrated multiple hypofluorescent spots. Oral prednisolone 30 mg/day was commenced while vemurafenib medication was ceased. Three weeks later, her vision improved, and serous retinal detachment subsided. However, her cutaneous melanoma recurred.Conclusions: Vemurafenib, a potential adjunct treatment for metastatic melanoma, was complicated by the development of panuveitis, papillitis, and multiple serous detachments. These ocular symptoms were similar to the presentation of acute VKH syndrome.
METHODS::Comprehensive reviews of the clinical characteristics and pathogenesis of Aicardi-Goutières syndrome (AGS), particularly its contextualization within a putative type I interferonopathy framework, already exist. However, recent reports of attempts at treatment suggest that an assessment of the field from a therapeutic perspective is warranted at this time. Here, we briefly summarize the neurological phenotypes associated with mutations in the seven genes so far associated with AGS, rehearse current knowledge of the pathology as it relates to possible treatment approaches, critically appraise the potential utility of therapies, and discuss the challenges in assessing clinical efficacy. WHAT THIS PAPER ADDS: Progress in understanding AGS disease pathogenesis has led to the first attempts at targeted treatment. Further rational therapies are expected to become available in the short- to medium-term.
METHODS::Purpose: To report the efficacy of adalimumab in a case of chronic Vogt-Koyanagi-Harada (VKH) disease refractory to conventional corticosteroids and immunosuppressive therapy and complicated by central serous chorioretinopathy (CSC).Case report: A 66-year-old woman diagnosed with VKH was treated with intravenous corticosteroids followed by oral corticosteroids and cyclosporine. However, systemic corticosteroids could not be tapered because of recurrent ocular inflammation and systemic complications (diabetes mellitus, moon face, bone weakness), while CSC appeared in both eyes. A diagnosis of chronic VKH resistant to medications complicated by corticosteroid-induced CSC was made. Systemic corticosteroids and cyclosporine were tapered and adalimumab initiated. Bilateral ocular inflammation and CSC were gradually reduced and visual acuity improved without any adverse effect. Twelve months after starting adalimumab monotherapy, no signs of active VKH and CSC were present.Conclusions: Adalimumab is one of the effective therapeutic options for refractory VKH disease complicated with corticosteroid-induced adverse effects.
