An unusual cause of stridor in childhood due to focal epileptic seizures

Respiratory disorders with stridor are a frequent cause of admission for children in an emergency department. Laryngospasm, as an isolated symptom of epilepsy, is a rare phenomenon [1, 3, 5]. Other respiratory symptoms of epilepsy, rarely seen in childhood, might be apnoeic spells [2, 4]. We report on a child with laryngospasm due to focal epileptic seizure

Trunk sway in mildly disabled multiple sclerosis patients with and without balance impairment

Multiple sclerosis (MS) causes a broad range of neurological symptoms. Most common is poor balance control. However, knowledge of deficient balance control in mildly affected MS patients who are complaining of balance impairment but have normal clinical balance tests (CBT) is limited. This knowledge might provide insights into the normal and pathophysiological mechanisms underlying stance and gait. We analysed differences in trunk sway between mildly disabled MS patients with and without subjective balance impairment (SBI), all with normal CBT. The sway was measured for a battery of stance and gait balance tests (static and dynamic posturography) and compared to that of age- and sex-matched healthy subjects. Eight of 21 patients (38%) with an Expanded Disability Status Scale of 1.0-3.0 complained of SBI during daily activities. For standing on both legs with eyes closed on a normal and on a foam surface, patients in the no SBI group showed significant differences in the range of trunk roll (lateral) sway angle and velocity, compared to normal persons. Patients in the SBI group had significantly greater lateral sway than the no SBI group, and sway was also greater than normal in the pitch (anterior-posterior) direction. Sway for one-legged stance on foam was also greater in the SBI group compared to the no SBI and normal groups. We found a specific laterally directed impairment of balance in all patients, consistent with a deficit in proprioceptive processing, which was greater in the SBI group than in the no SBI group. This finding most likely explains the subjective symptoms of imbalance in patients with MS with normal CBT

Tolerance of intravenous methylprednisolone for relapse treatment in demyelinating CNS disease

In Switzerland, the first course of intravenous steroids for treatment of episodes of demyelinating CNS disease is usually administered in an inpatient setting. We prospectively evaluated short term tolerance of treatment with special emphasis on sleep quality

[Cerebral vasculitis]

Cerebral vasculitis is a rare disease with a potentially harmful or even fatal outcome that often affects young adults. Primary autoimmune mediated disease can be distinguished from secondary vasculitis associated to infectious disorders, connective tissue diseases, malignancies or toxic drug effects. Pathomechanisms lead to destruction of the vessel wall and consecutive hemorrhagic or ischemic brain lesions. Beyond these mechanisms direct autoimmune mediated neurotoxicity is postulated. Clinical presentation is highly variable with potentially fluctuating signs and symptoms. Besides multifocal deficits from disseminated CNS involvement, diffuse encephalopathy or psychosis may result from diffuse CNS affection. For systemic vasculitis with CNS involvement, affection of joints, skin and organs may facilitate the diagnostic evaluation. CNS affection in systemic diseases is highly variable and may even precede systemic manifestation. The diagnostic work-up includes clinical evaluation, analysis of autoantibodies, MRI, digital subtraction angiography and biopsy of the affected tissue in doubtful cases. Standard therapy are corticosteroids often combined with immunosuppressants such as azathioprine, methotrexate or mycophenolate mofetil in chronic disease or cyclophosphamid in acute disorder. When therapy can be initiated timely, prognosis of cerebral vasculitis is usually favourable

Infantile spasms: does season influence onset and long-term outcome?

To study whether onset of infantile spasms manifests seasonal variation, as previously reported, and whether any such seasonality is associated with treatment response and long-term outcome, data for 57 patients were retrospectively reviewed. The data were collected from hospital files and through a mail survey of children with infantile spasms born from 1980 to 2002 and monitored at the University Children's Hospital of Berne, Switzerland. The mean age at time of onset of infantile spasms was 7 months (range, 0.75-40), at diagnosis 8 months (range, 1-42) and at follow-up 11.3 years (range, 1-23 years). In 77% of participants, the etiology of infantile spasms was known (symptomatic); in the remaining 23% it was not known (nonsymptomatic). In contrast to previous findings, onset of infantile spasms was not associated with calendar month, photoperiod, or global solar radiation. Long-term prognosis was poor: 4 of the 57 (7%) children died; 49 (86%) had cognitive impairment and 40 (70%) had physical impairment; 31 (54%) had cerebral palsy, 37 had (65%) persistent seizures, and 9 (16%) had Lennox-Gastaut syndrome. Symptomatic infantile spasms were associated with worse cognitive outcome (P < 0.001), but treatment modality and overall duration of infantile spasms were not. There was no association of calendar month or photoperiod at onset with cognitive outcome or treatment response

Disability progression in relapse-free multiple sclerosis patients on fingolimod versus interferon-beta/glatiramer acetate

BACKGROUND: Disability progression independent of relapses (PIRA) has been described as a frequent phenomenon in relapsing-remitting multiple sclerosis (RRMS). OBJECTIVE: To compare the occurrence of disability progression in relapse-free RRMS patients on interferon-beta/glatiramer acetate (IFN/GA) versus fingolimod. METHODS: This study is based on data from the Swiss association for joint tasks of health insurers. Time to relapse and 12-month confirmed disability progression were compared between treatment groups using multivariable Cox regression analysis with confounder adjustment. Inverse-probability weighting was applied to correct for the bias that patients on fingolimod have a higher chance to remain relapse-free than patients on IFN/GA. RESULTS: We included 1640 patients (64% IFN/GA, 36% fingolimod, median total follow-up time = 4-5 years). Disease-modifying treatment (DMT) groups were well balanced with regard to potential confounders. Disability progression was observed in 155 patients (8.8%) on IFN/GA and 51 (7.6%) on fingolimod, of which 44 and 23 were relapse-free during the initial DMT, respectively. Adjusted standard regression analysis on all patients indicated that those on fingolimod experience less frequently disability progression compared with IFN/GA (hazard ratio = 0.53 (95% confidence interval = 0.37-0.76)). After bias correction, this was also true for patients without relapses (hazard ratio=0.56 (95% confidence interval = 0.32-0.98). CONCLUSION: Our analysis indicates that fingolimod is superior to IFN/GA in preventing disability progression in both relapsing and relapse-free, young, newly diagnosed RRMS patients
