Serial MRI including diffusion and perfusion imaging was performed in a patient with hypertensive encephalopathy. At admission, the patient was disorientated and presented with seizures and cortical blindness. Perfusion imaging showed a marked reduction in blood volume and flow, with corresponding vasogenic oedema in the occipital, posterior temporal, and,(More)
A 52-year-old man developed diplopia, a nasal voice, dysphagia, hoarseness and slight bilateral facial palsies. There was no ataxia, areflexia, limb weakness or sensory involvement. Serum anti-GQ1b IgG antibody was present. Treatment with intravenous immunoglobulin started, and the patient responded with a rapid resolution of symptoms. The diagnosis is(More)
A 73-year-old man presented with a thunderclap headache (TCH), suggesting a subarachnoid haemorrhage. Neurological examination, computer tomography of the head, and cerebrospinal fluid examination were normal. Magnetic resonance imaging of the brain revealed a supratentorial cerebral infarct. No cerebral aneurysm could be detected. A TCH can be the(More)
Three intermediates in adenovirus assembly have been defined; nuclear intermediates, young virions, and mature virions. The nuclear intermediates are fragile and heterogenous in size (550S-670S) and withstand separation on ficoll gradients but fall apart upon CsCl gradient centrifugation unless prefixed with glutaraldehyde. They contain both capsid and core(More)
Temperature-sensitive mutants from three different complementation groups, ts5, ts19, and 6s58, have been shown to accumulate assembly intermediates at the restrictive temperature. The polypeptide composition of these intermediates is similar to that of the wild type, including the precursor polypeptides pVI, pVII, and pVIII. ts5 and ts19 also contained(More)
BACKGROUND Cluster headache is a primary headache by definition not caused by any known underlying structural pathology. However, symptomatic cases have been described, e.g. tumours, particularly pituitary adenomas, malformations, and infections/inflammations. The evaluation of cluster headache is an issue unresolved. CASE DESCRIPTION We present a case of(More)
Cluster headache is a primary headache by definition not caused by any known underlying structural pathology. Symptomatic cases have been described, for example tumours, dissections and infections, but a causal relationship between the underlying lesion and the headache is difficult to determine in many cases. The proper diagnostic evaluation of cluster(More)
Cluster headache (CH) is a primary headache, by definition not caused by any underlying structural pathology and belonging to the group of trigeminal-autonomic cephalalgias [1]. CH is the most frequent syndrome in this group. Although uncommon, symptomatic cases of CH have been described, e.g. tumours, particularly pituitary adenomas, malformations, and(More)
