The aims of this study were to investigate the frequency of dysphagia among patients with acute stroke and compare non-dysphagic and dysphagic stroke patients regarding demographic aspects, performance in activities of daily living and type of neurological deficiency and to test a bedside screening tool to identify patients with dysphagia. The frequency of dysphagia was found to be 27%, or 40% if those patients who were unconscious, terminally ill or had a previous history of dysphagia were included. Overall stroke severity seemed to be an indicator for dysphagia, i.e. being significantly more drowsy, more dependent in activities of daily living, suffering more often from dysarthria, expressive dysphasia, taking antidepressive medication, staying significantly longer in hospital and being discharged to a higher level of formal care than non-dysphagic patients. The screening method proved to be useful, in that it detected 77% of those with dysphagia using a review of medical charts and continuous observations as a method to check the reliability of the bedside method. It is concluded that most patients with dysphagia can be identified through systematic interviews, observations and test swallows. These have to be repeated and included in nursing care assessment. Overall stroke severity is an indicator of dysphagia.

The development of central pontine myelinolysis (CPM) has rarely been reported in association with hemophagocytic syndromes (HPS). Here we report a unique case of Epstein-Barr Virus (EBV)-related HPS which was accompanied with CPM. A 72-year-old man who had no significant medical history was admitted to our hospital due to high fever and progressing dysphasia and dysarthria. Physical examination revealed anisocoria of the right pupil, fixed reaction to light, and paralysis of the left vagus nerves. Magnetic resonance imaging revealed low signal intensity on T1-weighted images and high signal intensity T2-weighted images in the patient's central midpontine lesion. Initial work-up showed anemia and thrombocytopenia with elevated levels of serum ferritin, lactate dehydrogenase, and soluble IL-2 receptor. Bone marrow aspiration revealed hemophagocytosis. The EBV genome was detected in the peripheral blood using the polymerase chain reaction method. He was diagnosed as having EBV-related HPS and CPM. Despite intensive treatment with methylpredonisolone, immunoglobulin, and etoposide, he died due to progressive disease and fungal septicemia. The etiology and relation between CPM and HPS are discussed.

Surgical destruction of a portion of the ventrolateral nucleus of the thalamus is currently the procedure of choice for the treatment of incapacitating tremor and rigidity of parkinsonism. Seventy-three patients were treated by 105 thalamotomies at the University of Alberta Hospital and assessed one to four years later for improvement of function in everyday activities. Fifty-six patients were improved, 12 were unchanged, and five had died. Only two of the deaths were related to the operation. Paresis was permanent in only one patient. Twenty-five patients had bilateral operations and 22 of these showed improvement of function. Contraindications to operation include serious cardiovascular disease, mental deterioration, and those parkinsonian patients whose disability is chiefly due to akinesia, oculogyric crisis, dysphasia or dysarthria.

Three patients, two women aged 72 and 45 years, and a man aged 80 years, presented with transient neurological deficits due to a brain tumour, a glioblastoma multiforme and two meningiomas respectively. A fourth patient, an 84-year-old man, had a transient ischaemic attack (TIA) with a meningioma as an incidental finding. The first woman had normal CT findings, but MRI revealed the neoplasm. Symptoms included motor loss, sensory disturbances, dysphasia and dysarthria, lasting from 30 seconds up to 10 minutes. The first two patients had surgery; the first one later died when the tumour recurred. The other two patients still exhibit a spontaneous recovery. Of all patients with a clinical presentation of a TIA, 0.4-1% harbour a brain tumour. Clinical symptoms do not distinguish 'transient tumour attacks' from TIAs with a primarily vascular origin. Transient tumour attacks are mainly seen with meningiomas, and to a lesser extent with high-grade gliomas. Changes in intracranial pressure leading to focal ischaemia may explain the occurrence of this phenomenon. A part from intracerebral tumours, non-vascular entities mimicking TIAs can also be seen with demyelinating processes, metabolic disturbances, epilepsy or migraine. Brain imaging is always required in patients with transient neurological deficits. A CT scan may provide false-negative results and in case of doubt, MRI is the preferred diagnostic tool.

Mitochondrial (mt)DNA alterations cause cellular energy failure and respiratory chain dysfunction. Single large-scale rearrangements represent the most common mtDNA mutations and are responsible for very variable clinical manifestations. Here, we show an increased frequency of the A12308G substitution, a common polymorphism used to define the European mtDNA haplogroup U, in mitochondrial patients carrying mtDNA single macrodeletion. In this group of patients, A12308G substitution is associated with a higher relative risk of developing pigmentary retinal degeneration, short stature, dysphasia-dysarthria and cardiac conduction defects. MtDNA haplotype might modulate the clinical expression of mitochondrial encephalomyopathies due to mtDNA macrodeletions.

There are few reports of central pontine myelinolysis after living donor liver transplantation. A 59-year-old male received a right liver graft from his daughter for hepatitis B-related liver cirrhosis. Methylprednisolone and tracrolimus were used for immunosuppression. Dysarthria and dysphasia were noted on the second postoperative day. Brain magnetic resonance image taken on the 9th postoperative day revealed a hyperintense area at the center of his pons in T2-weighted images. The symptoms improved spontaneously 1 month after the operation. Central pontine myelinolysis should be included in the differential diagnosis when neurologic manifestations are observed after living donor liver transplantation.

We report a 55-year-old right-handed Japanese man with motor neuron disease and dysgraphia of kana letters. He was admitted to our hospital because of dysarthria and dysphasia. On admission, the results of general physical examination were within normal limits. Neurological examination revealed severe dysarthria, dysphasia, impaired movement of the tongue without fasciculation and slight distal muscle weakness in the bilateral upper limbs. There were no fasciculation of the muscle. Deep tendon reflexes were hyperactive without Babinski's signs. Sensation, coordination, and gait were normal. Neurophysiological studies demonstrated normal motor nerve conduction velocities and sensory action potential. The results of needle electromyography of the upper limbs were compatible with motor neuron disease (MND). Magnetic resonance imaging (MRI) showed atrophy of the bilateral temporal region of the brain. 99mTc-HMPAO SPECT (Single Photon Emission Computed Tomography) showed reduced uptake of tracer in the bilateral temporal region. On neuropsychological examination, his behavior was normal, and orientation and intelligence were also preserved, but his speech was severely impaired. Reading comprehension was slightly impaired. In regard to writing comprehension, he had no difficulty in copying of words though dictation was found to be impaired. He omitted one kana letter in a word. Agraphia is accompanied by various factors such as aphasia, dementia, agnosia, alexia. But in this case at least for early stage, agraphia existed without other higher cortical dysfunction. He did not show severe dementia in his early stage of his disease, but developed it later in the disease's progression. In this case, agraphia might be due to the atrophic changes in the temporal lobe.

A 23 year-old woman presented with dysarthria, hoarseness, dysphasia, ataxia and dyspnoea. MRI showed a mass of heterogeneous intensity at the dorsal medulla oblongata. Laboratory studies revealed high serum alpha-fetoprotein (AFP) and beta-subunit human chorionic gonadotropin (beta-HCG) levels. No other tumours were found on systemic investigation. An intracranial non-germinomatous germ cell tumour (NGGCT) was strongly suspected. The patient received combination chemotherapy using ifosfamide, cisplatin, and etoposide and local irradiation to a total of 52 Gy. Serum AFP and beta-HCG levels normalized after four cycles of chemotherapy and she became asymptomatic apart from mild postural hypotension. A follow-up MRI showed only a tiny residual lesion in the medulla oblongata, which has been stable for more than three years. Surgical resection should be carefully considered in patients with brainstem tumours with elevation of serum tumour markers as chemo- and radiotherapy may be effective for brainstem NGGCT.

Leigh syndrome is a mitochondrial disease of infancy and early childhood and is rare in adults. We report an autopsy case of adult Leigh syndrome of 15 years duration in a 32-year-old man with a familial history of the disease. His initial symptom was clumsiness followed by dullness, and dysphasia and dysarthria appeared in the last 3 months. His brother had similar symptoms and died at the age of 27 years. His sister is also demented. Cranial MRI revealed abnormal signals in the bilateral putamen and tegmentum of the brainstem. Neuropathologically, there were symmetrical, well-demarcated necrotizing lesions with proliferation of capillaries in the putamen, caudate nucleus and thalamus, as well as in the periaqueductal gray matter of the midbrain and tegmentum of the pons. It seems that the lesions in the putamen were more severe and older than those of the brainstem, the latter having numerous macrophage infiltrations. Neuronal loss and gliosis were also observed in the substantia nigra and cerebellar cortex. This is the first autopsy-confirmed familial adult Leigh syndrome in China. The clinicopathological features are presented together with a literature review.

We have studied the configuration of the cortico-subcortical language networks within the right hemisphere (RH) in nine left-handers, being operated on while awake for a cerebral glioma. Intraoperatively, language was mapped using cortico-subcortical electrostimulation, to avoid permanent deficit. In frontal regions, cortical stimulation elicited articulatory disorders (ventral premotor cortex), anomia (dorsal premotor cortex), speech arrest (pars opercularis), and semantic paraphasia (dorsolateral prefrontal cortex). Insular stimulation generated dysarthria, parietal stimulation phonemic paraphasias, and temporal stimulation semantic paraphasias. Subcortically, the superior longitudinal fasciculus (inducing phonological disturbances when stimulated), inferior occipito-frontal fasciculus (eliciting semantic disturbances during stimulation), subcallosal fasciculus (generating control disturbances when stimulated), and common final pathway (inducing articulatory disorders during stimulation) were identified. These cortical and subcortical structures were preserved, avoiding permanent aphasia, despite a transient immediate postoperative language worsening. Both intraoperative results and postsurgical transitory dysphasia support the major role of the RH in language in left-handers, and provide new insights into the anatomo-functional cortico-subcortical organization of the language networks in the RH-suggesting a "mirror" configuration in comparison to the left hemisphere.
