Abstract

BACKGROUND:Several studies have identified changes in the spinal cord DTI measurements in patients with multiple sclerosis (MS). However, correlations between changes in DTI parameters in normal appearing cervical spine and neurological findings have not been clearly established. OBJECTIVES:To determine whether diffusion tensor imaging (DTI) measurements such as fractional anisotropy (FA) and apparent diffusion coefficient (ADC) are sufficiently sensitive in detecting microstructure alterations in normal-appearing spinal cords in patients with MS and whether they reflect these patients' clinical disability. MATERIAL AND METHODS:Fifteen patients diagnosed with relapsing-remitting MS (RRMS) with normal-appearing cervical spinal cords on plain MRI and 11 asymptomatic volunteers were enrolled in the study. Overall, 75 cervical spinal segments were analyzed. The regions of interest were drawn from the entire spinal cord cross-section and in the normal-appearing white matter tracts: the superior and inferior cerebellar peduncles and the posterior limbs of the internal capsules. Neurological deficit and the level of disability were evaluated using the Expanded Disability Status Scale (EDSS), the timed 25-foot walk test (T25FW) and the 9-hole peg test (9HPT) for manual dexterity. RESULTS:A significant difference (p < 0.05) in FA values between patients with MS and the control group was found at levels C2 (p = 0.047) and C3 (p = 0.023). No significant changes in ADC values were found. There was correlation between FA and ADC values in selected white matter tracts and at particular spinal cord levels. We also observed significant correlations between diffusion tensor imaging parameters and manual dexterity. CONCLUSIONS:Our preliminary results may suggest that the spinal cord's structural loss is the dominant factor in the inflammatory/demyelinating component in patients with MS. Diffusion tensor imaging changes in the spinal cord correlate with brain DTI changes. Manual functioning seems to be more affected than walking.

摘要

背景: 一些研究已经确定了多发性硬化 (MS) 患者脊髓DTI测量的变化。然而,正常出现颈椎的DTI参数变化与神经系统检查结果之间的相关性尚未明确。 目的: 确定弥散张量成像 (DTI) 测量值,如各向异性分数 (FA) 和表观弥散系数 (ADC)。在检测MS患者正常脊髓的微结构改变以及它们是否反映这些患者的临床残疾方面足够敏感。 材料和方法: 15 例诊断为复发-缓解型MS (RRMS) 且颈椎MRI表现正常的患者和 11 例无症状志愿者入选研究。总体而言,分析了 75 个颈椎节段。感兴趣的区域来自整个脊髓横截面和正常外观的白质束: 小脑脚上部和下部以及内囊的后肢。神经功能缺损及伤残等级进行比较,该扩展残疾状态量表 (EDSS),定时 25 英尺步行test (T25FW) 和 9 洞peg test (9HPT) 对于手动灵巧。 结果: MS患者和对照组之间的FA值在C2 (p = 0.05) 和C3 (p = 0.047) 水平存在显著差异 (p <0.023)。未发现ADC值有明显变化。所选白质束和特定脊髓水平的FA和ADC值之间存在相关性。我们还观察到弥散张量成像参数与手法灵巧之间存在显著相关性。 结论: 我们的初步结果可能表明,脊髓的结构缺失是MS患者炎症/脱髓鞘成分的主导因素。脊髓弥散张量成像变化与脑DTI变化相关。手动功能似乎比步行更受影响。

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.
