[Wilson's disease: a clinical case is presented with neuropsychiatric dominant form and probable physiopathology interpretation with magnetic resonance of the brain].

Case Report: A clinical case of Wilson's disease is presented. She was a 26 years old woman who began to show psychological symptoms, and later developed neurological signs such as asymmetrical hand tremor, parkinsonism, dystonia and later dysphagia and mutism. The ophthalmological examination found a Kayser Fleischer ring in the Descemet membrane.

[Wilson'S disease: dominant neuropsychiatric form. Case presentation and its physiopathologic interpretation based upon magnetic resonance of the encephalon].

This is a presentation of a clinical case of Wilson s disease. The patient is a 26 year old woman who began to evidence psychological symptoms, which were later accompanied by neurological manifestations such as asymmetrical hand tremor, parkinsonism, dystonia and later on, dysphagia and mutism. The ophthalmological examination found a Kayser Fleischer ring in Descemet s membrane.

Upper extremity neuropathies in patients with spinal cord injuries.

We present a cross-sectional study designed to screen and evaluate 19 male patients with acute or chronic spinal cord injury for the presence of carpal tunnel syndrome (CTS) and radial neuropathies (RNP) in order to establish the prevalence of CTS and RNP, to compare characteristics of persons with spinal cord injury who do not have these neuropathies, to evaluate the effects of their activities and to define the causation of these neuropathies in order to prevent their occurrence during and after the rehabilitation process. Patients admitted to the Spinal Cord Injury Service with acute and chronic spinal injury (below C3) were included in the study. The level of activity was determined with the Functional Independence Measure (FIM) Score.

Short-term changes in the response characteristics of the human visual evoked potential.

The present study examined how the response characteristics of the visual evoked potential (VEP) varied during the course of trials using a sinusoidal grating stimulus that reversed contrast in a square-wave manner. To accomplish this, amplitude and phase values were derived in short segments during the course of continuous stimulation for three subjects. When stimulus spatial frequencies of 0.

[Advances in gastrointestinal hormones: cholecystokinin].

Cholecystokinin (CCK) and gastrin are members of an important family of gastroenteropancreatic polypeptides. Distribution of CCK both in the digestive system and central and peripheral nervous structures correlates with the variety of its actions; more than a classic hormone, CCK is a peptidergic neurotransmitter. CCK plays a predominant role in multiple digestive functions: contraction and emptying of the gallbladder, stimulation of pancreatic secretion of enzymes, delay of gastric emptying, diminution of gastric acid secretion, regulation of insulin secretion, reduction of food intake, etc.
