The few studies addressing semiology of psychogenic nonepileptic seizures (PNES) in children showed that this group differs from adults, considering the classical signs described. Our study with systematic assessment provides a direct comparison of the classical signs of psychogenic nonepileptic seizures (PNESs) in children and adults in order to establish the usefulness of the most important s...

P eriventricular leucomalacia is an end stage lesion that results from hypoxic-ischaemic injury to the white matter of the developing brain. This condition occurs in 32% of premature infants and is believed to develop between the 24th and 34th weeks of gestation. Periventricular leucomalacia most commonly involves the optic radiations adjacent to the trigone of the lateral ventricle, and the an...

We have analysed retrospectively the clinical features and electroencephalograms in 35 patients with complex partial seizures of temporal lobe origin who were seizure-free after epilepsy surgery. Two groups were differentiated for statistical analysis: 16 patients had hippocampal temporal lobe seizures (HTS) and 19 patients had extrahippocampal temporal lobe seizures (ETS) associated with a sma...

It is often assumed that the information representations used in interactive information systems are grounded firmly and objectively in mathematics. This positivist view is at odds, however, with contemporary mathematics and philosophy of science, which sees subjective, social, and situated symbol systems — semiology — at the base of all human information use. We describe some of the reasons be...

CLINICAL CASE A patient with acute amaurosis due central retinal artery occlusion (CRAO), who had mitral regurgitation and Streptococcus viridans positive blood cultures. Using transesophageal ultrasound, the patient was diagnosed with native valve infective endocarditis without fever, and with loss of vision as the only symptom. DISCUSSION CRAO due to infective endocarditis is rare and there...

Tardive tremor is a 3–5 Hz bilateral resting and action tremor, associated with the use of dopamine receptor blocking drugs, accompanied by other tardive movement disorders and responsive to tetrabenazine or clozapine. We describe a case of a sensory trick associated with tardive tremor which raises important points about semiology and management. First, the presence of a sensory trick with tar...

The review concerning a value of magnesium in an organism in healthy persons and cases with endocrine disorders is presented. The causes of magnesium-deficient conditions in cases with type 1 and type 2 diabetes, thyrotoxic goiter, hypothyroidism and obesity were analyzed. Participation of magnesium in secretion of parathormone and a control of calcium exchange is shown. The clinical semiology ...

Systematic localization of the epileptic zone and procedures for surgical resection are not recent developments in the treatment of epilepsy. based on the work of Hughlings Jackson. Between 1890 and 1910, Horsley reported series of patients who received craniotomy for the treatment of symptomatic epilepsy from a known cause, often traumatic. Wilder Penfield and Herbert Jasper, and many others f...

Frontal lobe epilepsy makes up between 20 and 30% of all partial epilepsies and is the biggest subgroup of the extratemporal lobe epilepsies. Of the patients who undergo surgery for epilepsy up to 18% have a frontal lobe focus. The aetiology of frontal lobe epilepsy is varied, clinical semiology is diverse and seizures are often frequent, disabling and refractory to treatment. Imaging and EEG f...
