Abstract
This study applies an upper extremity model to analyze motion in 25 children with cerebral palsy using posterior walkers. The study indicates that throughout a gait cycle, the shoulders and wrist are in extension and the elbows are flexed. It also reveals that the elbows are the most asymmetrical joint of the upper extremities during walker-assisted ambulation.

Abstract
Ankle foot orthoses (AFOs) are prescribed for ambulatory children with spastic diplegia to improve biomechanical alignment and functional capability. The purpose of this study was to employ quantitative motion analysis of the lower extremity to investigate two rehabilitative orthotics. The effects of hinged ankle foot orthoses (HAFO) and dynamic ankle foot orthoses (DAFO) for joint ankle management in children with cerebral palsy were compared. Sixteen (16) independently ambulatory children with a diagnosis of spastic diplegic cerebral palsy (7.5 +/- 2.9 yrs.) were included in the study. The biomechanical effects of two AFO designs were compared to barefoot using a 3-D motion analysis system. Significant differences between braced and unbraced conditions were found in peak ankle dorsiflexion, and peak ankle plantarflexion, knee stance peak flexion, knee swing peak flexion, hip stance peak flexion, and peak ankle plantarflexion moment (p < 0.01). Differences between the HAFO and DAFO were not seen in the kinematic and kinetic metrics. Further development of dynamic testing is suggested in order to advance our understanding of orthotic intervention. The value of quantitative description of gait dynamics is clearly indicated for rehabilitative application.

Abstract
We report on two unrelated patients clinically presenting with late-onset progressive limb girdle weakness; cardiomyopathy was seen in one patient. Muscle biopsy revealed a necrotic myopathy with numerous rimmed vacuoles, ultrastructurally typical paired-helical filaments, and reduced immunohistochemical staining for alpha-dystroglycan. Quadriceps sparing hereditary inclusion body myopathy due to mutations in GNE gene, and OPMD due to PABPN1 mutations were excluded, genetically. We detected a homozygous mutation of the FKRP gene (826C>A) in both patients. Mutations of FKRP have been reported in congenital muscular dystrophies, LGMD2I, cardiomyopathy and hyperCKemia, but not in myopathies with vacuoles and paired-helical filaments. Therefore, our findings further extend the morphological variability of muscular dystrophies due to FKRP mutations.

Abstract
Evoked potentials (EP) have a role in making the diagnosis of multiple sclerosis (MS) but their implication for predicting the future disease course in MS is under debate. EP data of 94 MS patients examined at first presentation, and after five and ten years were retrospectively analysed. Patients were divided into two groups in relation to the prior duration of disease at the time point of first examination: group 1 patients (n=44) were first examined within two years after disease onset, and group 2 patients (n=50) at later time points. As primary measures sum scores were calculated for abnormalities of single and combined EP (visual (VEP), somatosensory (SEP), magnetic motor evoked potentials (MEP)). In patients examined early after disease onset (group 1), a significant predictive value for abnormal EP was found with MEP and SEP sum scores at first presentation correlating significantly with Expanded Disability Status Scale (EDSS) values after five years, while the VEP sum score was not. The cumulative number of abnormal MEP, SEP and VEP results also indicated higher degrees of disability (EDSS > or = 3.5) after five years. Combined pathological SEP and MEP findings at first presentation best predicted clinical disability (EDSS > or = 3.5) after five years (odds ratio 11.0). EP data and EDSS at first presentation were not significantly linked suggesting that EP abnormalities at least in part represented clinically silent lesions not mirrored by EDSS. For patients in later disease phases (group 2), no significant associations between EP data at first presentation and EDSS at five and ten years were detected. Together with clinical findings and MR imaging, combined EP data may help to identify patients at high risk of long-term clinical deterioration and guide decisions as to immunomodulatory treatment.

Abstract
Out-of-body experiences are reported in a variety of diseases and physiologic conditions. We report a 44-year-old patient with epigastric auras, psychomotor and grand mal seizures, and paroxysmal experiences during which he believed to have left his body and seen himself from the outside. Electroencephalography showed a right temporal and right parietal seizure pattern on several occasions, and a lesion in the right parietal lobe was detected by cranial magnetic resonance imaging. Histological examination showed a pleomorphic xanthoastrocytoma. Following extirpation of the lesion, the patient has been seizure-free for 5 years.

Abstract
Abstract5F11, a fully human monoclonal antibody directed against CD30, effectively induces killing of CD30-expressing lymphoma cell lines in vitro and in animal models. A recently conducted phase 1/2 study shows that 5F11 is well tolerated in heavily pretreated patients with relapsed and refractory CD30+ lymphoma and has some clinical activity. In the present study, we demonstrate that 5F11 activates nuclear factor κB (NF-κB) and the anti-apoptotic protein cellular FLICE (Fas-associating protein with death domain-like interleukin-1β-converting enzyme) inhibitory protein (c-flip) in Hodgkin lymphoma (HD)-derived cell lines, which might cause apoptosis resistance, thus limiting the clinical use of 5F11. To overcome this resistance, we combined 5F11 with the proteasome inhibitor bortezomib, which has been shown to suppress NF-κB activity. This combination revealed a synergistic cytotoxic effect in vitro and in a human HD xenograft model provided that 5F11 precedes bortezomib treatment. We conclude that initial 5F11-mediated NF-κB signaling sensitizes the tumor cells to bortezomib-induced cell death. These data suggest a therapeutic value of this combination for HD patients.

Abstract
Chronic myelitis from Whipple's disease of the spinal cord is extremely rare. The differential diagnosis includes chronic inflammatory lesions, viral or bacterial infections, and tumours of the spinal cord. Here we present a 50-year-old man with mild sensory deficits because of a large lesion of the cervical spinal cord who markedly showed improvement during probatory antibiotic therapy. PCR and jejunal biopsy were initially negative and only later confirmed the diagnosis of Whipple's disease. Clinical and neuroradiological criteria are suggested which may be of help in the early diagnosis of spinal Whipple's disease before confirmation by molecular biology or histology.

Abstract
Recently, the vagus nerve has gained particular interest in neuropsychiatry, as neurodegenerative diseases like Alzheimer's and Parkinson's disease are supposed to affect the brainstem nuclei of the vagus nerve early in their course. In addition, electric stimulation of the vagus nerve has therapeutic effects in otherwise therapy-refractory epilepsies and depressions. So far, no method is available to assess vagus nerve function in this context. On this background and based on the established techniques of early acoustic evoked potentials we investigated if a transcutaneous electric stimulation of the sensory auricular branch of the vagus nerve innervating parts of the outer ear is feasible in healthy subjects using this hypothesis-generated approach. We were able to record a clear, reproducible Vagus Sensory Evoked Potential (VSEP) measured as far field potential probably originating in vagus nuclei in the brainstem. Further studies are needed to test the interindividual stability and test-retest reliability of this new method before potential diagnostic and therapeutic applications might be evaluated.

Abstract
The authors report three patients with chronic sciatic pain without focal neurologic deficit. Sitting or lying on the affected side provoked pain, and standing and walking relieved it. MRI revealed varicotic gluteal vessels compressing the sciatic nerve. Decompression of the nerve resulted in complete and permanent pain relief. Sciatic or buttock pain in patients with varicosities and pain provocation in the sitting or lying position suggests this neurovascular compression syndrome.

Abstract
The authors studied standard autonomic function tests and measures of heart rate variability in 60 patients with multiple sclerosis (MS) and correlated results with the Fatigue Severity Scale and the Modified Fatigue Impact Scale. The authors found that autonomic responses correlated with fatigue resembling a hypoadrenergic orthostatic response, possibly due to a sympathetic vasomotor lesion with intact vagal heart control. Treatments to control sympathetic dysfunction for MS-associated fatigue deserve further study.
