Ipsilateral facial weakness in upper medullary infarction-supranuclear or infranuclear origin?
1999
We describe two patients with upper medullary infarctions showing ipsilateral facial weakness and relative sparing of the upper facial muscles. Electrophysiological follow-up using transcranial magnetic stimulation of the motor cortex in combination with stimulation of the peripheral facial nerve disclosed a supranuclear (corticofacial) tract lesion in one patient and a partial nuclear/infranuclear intra-axial facial nerve lesion in another.
Anosognosia for hemiparesis after left-sided stroke
2014
In patients with left-sided lesions, anosognosia for hemiparesis (AHP) seems to be a rare phenomenon. It has been discussed whether this rareness might be due to an inevitable bias due to language dysfunction and whether the left hemisphere's role for our self-awareness of motor actions thus is underestimated. By applying functional magnetic resonance imaging (fMRI) we examined whether patients with AHP following a left hemisphere stroke show a regular, left-sided or a reversed, right-sided lateralization of language functions. Only the former observation would argue for an original role of the left hemisphere in self-awareness about limb function. In a consecutive series of 44 acute left-s…
Positional brain ischemia with MCA occlusion successfully treated with extra-intracranial bypass.
2010
408 Positional cerebral ischemia (PCI) is an extremely rare condition in which dramatic central nervous system deficits are triggered by standing in patients with severe stenosis or occlusion of the major brain-supplying blood vessels [1] . Because PCI is generally associated with orthostatic hypotension [2, 3] , a hemodynamic mechanism has been proposed [4] . However, PCI has been reported even in patients without orthostatic hypotension [1] . The treatment is medical, but surgery can be considered in refractory cases (endarterectomy for carotid artery stenosis or either highor low-flow extra-intracranial bypass – for carotid occlusion) [3] . We report a case of PCI associated with middle …
MOTOR DYSFUNCTION OF THE "NON AFFECTED" LOWER LIMB: A KINEMATIC COMPARATIVE STUDY BETWEEN HEMIPARETIC STROKE AND TOTAL KNEE PROSTHESIZED PATIENTS
2009
In patients with hemispheric stroke, abnormal motor performances are described also in the ipsilateral limbs. They may be due to a cortical reorganization in the unaffected hemisphere; moreover, also peripheral mechanisms may play a role. To explore this hypothesis, we studied motor performances in 15 patients with hemispheric stroke and in 14 patients with total knee arthroplasty, which have a reduced motility in the prosthesized leg. Using the unaffected leg, they performed five superimposed circular trajectories in a prefixed pathway on a computerized footboard, while looking at a marker on the computer screen. The average trace error was significantly different between the groups of pat…
Acute painful paraplegia in a 49-year-old man with allergic asthma.
2014
We present a case of a 49-year-old man, with a 10-year history of bronchial asthma and nasal polyposis, who developed acutely painful paraplegia and paresthesias. Laboratory data showed elevated blood creatine kinase levels and myoglobinuria, which were diagnostic for rhabdomyolysis but only partially explained the neurological deficit. Electrophysiological studies revealed a sensorimotor neuropathy of multiple mononeuritis type. The patient also had leucocytosis with marked eosinophilia and antineutrophil cytoplasmic autoantibodies. Bronchial biopsies showed inflammatory infiltrates with a prevalence of eosinophils. All these findings led us to diagnose eosinophilic granulomatosis with pol…
Thigh muscle function in stroke patients revealed by velocity-encoded cine phase-contrast magnetic resonance imaging.
2008
Current methods of clinical assessment of muscle coordination and function after stroke do not provide information on deep muscles. The objective of this study was to examine how stroke affects both superficial and deep muscles' coordination and whether muscle function improves after rehabilitation. Muscle function, coordination, and activity of quadriceps femoris (QF) and hamstrings were evaluated in 10 stroke patients with mild hemiparesis and in 6 controls using velocity-encoded cine phase-contrast magnetic resonance imaging (VE-PC MRI), surface electromyography (sEMG), and maximal voluntary isometric contraction torque (MVC). At baseline, the peak muscle velocity of the rectus femoris (…
Electromyographic comparison of elastic resistance and machine exercises for high-intensity strength training in patients with chronic stroke
2016
To investigate whether elastic resistance training can induce comparable levels of muscle activity as conventional machine training in patients with chronic stroke.Comparative study.Outpatient rehabilitation facility.Stroke patients (N=18) with hemiparesis (mean age, 57 ± 8y).Patients performed 3 consecutive repetitions at 10 repetition maximum of unilateral knee extension and flexion using elastic resistance and conventional machine training.Surface electromyography was measured in vastus lateralis, vastus medialis, biceps femoris, and semitendinosus and was normalized to maximal electromyography (% of max) of the nonparetic leg.In the paretic leg, agonist muscle activity ranged from 18% t…
Tight Link Between Our Sense of Limb Ownership and Self-Awareness of Actions
2007
Background and Purpose— Hemiparetic stroke patients with disturbed awareness for their motor weakness (anosognosia for hemiparesis/-plegia [AHP]) may exhibit further abnormal attitudes toward or perceptions of the affected limb(s). The present study investigated the clinical relationship and the anatomy of such abnormal attitudes and AHP. Methods— In a new series of 79 consecutively admitted acute stroke patients with right brain damage and hemiparesis/ -plegia, different types of abnormal attitudes toward the hemiparetic/plegic limb (asomatognosia, somatoparaphrenia, anosodiaphoria, misoplegia, personification, kinaesthetic hallucinations, supernumerary phantom limb) were investigated. Re…
Safety of a 3-weekly schedule of carboplatin plus pegylated liposomal doxorubicin as first line chemotherapy in patients with ovarian cancer: prelimi…
2006
Abstract Background The MITO-2 (Multicentre Italian Trials in Ovarian cancer) study is a randomized phase III trial comparing carboplatin plus paclitaxel to carboplatin plus pegylated liposomal doxorubicin in first-line chemotherapy of patients with ovarian cancer. Due to the paucity of published phase I data on the 3-weekly experimental schedule used, an early safety analysis was planned. Methods Patients with ovarian cancer (stage Ic-IV), aged 2, every 3 weeks or to carboplatin AUC 5 plus pegylated liposomal doxorubicin 30 mg/m2, every 3 weeks. Treatment was planned for 6 cycles. Toxicity was coded according to the NCI-CTC version 2.0. Results The pre-planned safety analysis was performed…
Percepción del alumnado sobre evaluación formativa y compartida: conectando dos universidades a través de la Blogosfera
2017
The aim of this study was to evaluate differences in physical education students’ perception on an educational innovation based on formative and peer assessment through the blogosphere. The sample was made up of 253 students from two Spanish universities. Data was collected using a self-reported questionnaire and t tests were employed in order to find differences among students’ groups. Results show significant differences in almost all of the items on which the students were questioned. Basque students were more satisfied with the assessment tool used than the Valencian students. Students found the blogosphere more active, meaningful, functional and motivating and that it made for collabor…
