The relationship between the rate of brain volume loss during first 24 months and disability progression over 24 and 48 months in relapsing MS

Clinical evidence in patients with relapsing-remitting multiple sclerosis suggests an association between MRI outcome measures and disability progression (DP). Post hoc analysis to investigate the association and potential predictive value of brain volume loss (BVL) with long-term DP in FREEDOMS. Patients were categorized into quartiles by SIENA-calculated percent brain volume change from baseline to month (M) 24. Patient characteristics at baseline were determined for each quartile, as were the proportions of patients at M24 and M48 reaching Expanded Disability Status Scale (EDSS) scores of ≥4.0 or ≥6.0 or DP confirmed at 3 months (CDP3) or 6 months (CDP6), and change in EDSS and Multiple Sclerosis Functional Composite. MS disease activity and severity as well as brain volume at baseline were predictive of subsequent BVL over 24 months. The quartiles of patients with greater BVL at 24 months were at highest risk (odds ratio, p value) for reaching EDSS ≥4 (2.8, p = 0.001) or ≥6 (5.73, p = 0.0005) and experienced more DP at M24 (CDP3 2.13, p = 0.002; CDP6 2.17, p = 0.003) and M48 (CDP3 1.98, p = 0.006; CDP6 1.87, p = 0.018) compared to the quartile of patients with the least amount of BVL. These findings confirm the clinical relevance of early brain volume changes for long-term DP.

Effectiveness and Limitations of Unsupervised Home-Based Balance Rehabilitation with Nintendo Wii in People with Multiple Sclerosis

Balance training represents a critical part of the rehabilitation process of individuals living with multiple sclerosis (MS) since impaired postural control is a distinctive symptom of the disease. In recent years, the use of the Nintendo Wii system has become widespread among rehabilitation specialists for this purpose, but few studies have verified the effectiveness of such an approach using quantitative measures of balance. In this study, we analyzed the postural sway features of a cohort of twenty-seven individuals with MS before and after 5 weeks of unsupervised home-based balance training with the Wii system. Center of pressure (COP) time-series were recorded using a pressure platform and processed to calculate sway area, COP path length, displacements, and velocities in mediolateral (ML) and anteroposterior (AP) directions. Although the results show a significant reduction in sway area, COP displacements, and velocity, such improvements are essentially restricted to the ML direction, as the Wii platform appears to properly stimulate the postural control system in the frontal plane but not in the sagittal one. Available Wii games, although somewhat beneficial, appear not fully suitable for rehabilitation in MS owing to scarce flexibility and adaptability to MS needs and thus specific software should be developed.

Fulminant demyelinating encephalomyelitis

Objectives:

Antibodies to myelin oligodendrocyte glycoprotein (MOG) are detectable in inflammatory demyelinating CNS diseases, and MOG antibody–associated diseases seem to have a better prognosis despite occasionally severe presentations.

Methods:

We report the case of a 71-year-old patient with acute visual and gait disturbance that dramatically worsened to bilateral amaurosis, tetraplegia, and respiratory insufficiency within a few days.

Results:

MRI showed multiple progressive cerebral and spinal lesions with diffusion restriction (including both optic nerves) and marginal contrast enhancement. Routine blood and CSF measures including oligoclonal bands were normal. At disease onset, MOG immunoglobulin G was detected (serum titer 1:1,280, corresponding CSF titer was 1:20) and remained positive in patient serum. Aquaporin-4 antibodies were absent at disease onset but seroconverted to positive at week 9. In addition, CSF glial fibrillary acid protein and myelin basic protein levels were very high at onset but decreased during disease course. After 4 months, the patient died despite immunomodulatory treatment. Postmortem neuropathologic examination revealed an acute multiple sclerosis (MS) defined by multiple demyelinating lesions with a pronounced destructive component and loss of astrocytes. Lesion pattern of optic chiasm met MS pattern II characterized by antibody and complement-mediated demyelination.

Conclusion:

The case with the clinical presentation of an acute demyelinating encephalomyelitis with predominant optic and spinal involvement, absent oligoclonal bands, a histopathology of acute MS pattern II and development of aquaporin-4 antibodies extends the spectrum of MOG antibody–associated encephalomyelitis. Although, MOG antibodies are suspected to indicate a favorable prognosis, fulminant disease courses are possible and warrant an aggressive immunotherapy.

Emergency medicine and internal medicine trainees’ smartphone use in clinical settings in the United States

Purpose:
Smartphone technology offers a multitude of applications (apps) that provide a wide range of functions for healthcare professionals. Medical trainees are early adopters of this technology, but how they use smartphones in clinical care remains unclear. Our objective was to further characterize smartphone use by medical trainees at two US academic institutions, as well as their prior training in the clinical use of smartphones.
Methods:
In 2014, we surveyed 347 internal medicine and emergency medicine resident physicians at the University of Utah and Brigham and Women’s Hospital about their smartphone use and prior training experiences. Scores (0%–100%) were calculated to assess the frequency of their use of general features (email, text) and patient-specific apps, and the results were compared according to resident level and program using the Mann-Whitney U test.
Results:
A total of 184 residents responded (response rate, 53.0%). The average score for using general features, 14.4/20 (72.2%) was significantly higher than the average score for using patient-specific features and apps, 14.1/44(33.0%; P < 0.001). The average scores for the use of general features, were significantly higher for year 3–4 residents, 15.0/20 (75.1%) than year 1–2 residents, 14.1/20 (70.5%; P=0.035), and for internal medicine residents, 14.9/20 (74.6%) in comparison to emergency medicine residents, 12.9/20 (64.3%; P = 0.001). The average score reflecting the use of patient-specific apps was significantly higher for year 3–4 residents, 16.1/44 (36.5%) than for year 1–2 residents, 13.7/44 (31.1%; P = 0.044). Only 21.7% of respondents had received prior training in clinical smartphone use.
Conclusions:
Residents used smartphones for general features more frequently than for patient-specific features, but patient-specific use increased with training. Few residents have received prior training in the clinical use of smartphones.

7T MRI in natalizumab-associated PML and ongoing MS disease activity

Objective:

To assess the ability of ultra-high-field MRI to distinguish early progressive multifocal leukoencephalopathy (PML) from multiple sclerosis (MS) lesions in a rare case of simultaneous presentation of natalizumab–associated PML and ongoing MS activity.

Methods:

Advanced neuroimaging including 1.5T, 3T, and 7T MRI with a spatial resolution of up to 0.08 mm3 was performed.

Results:

7T MRI differentiated between PML-related and MS-related brain damage in vivo. Ring-enhancing MS plaques displayed a central vein, whereas confluent PML lesions were preceded by punctate or milky way–like T2 lesions.

Conclusions:

Given the importance of early diagnosis of treatment-associated PML, future systematic studies are warranted to assess the value of highly resolving MRI in differentiating between early PML- and MS-induced brain parenchymal lesions.
