RESUMO
Wilson disease is an inborn error of copper metabolism that has neurological and hepatic manifestations. We report a 13 years old girl and a 12 years old boy with Wilson disease. In both patient, brain computed tomography and magnetic resonance imaging showed marked involvement of basal ganglia and other deep gray nuclei. Considering that this is a treatable disease, it should be included in the differential diagnosis of the so called "striatal necrosis of childhood".

We report a 50 years old woman admitted to the hospital due to progressive dysphagia and disarthria of there weeks duration. On admission a right hemiparesis was noted. CSF examination showed a protein of 9 mg/dl and no cells. A brain CAT scan showed rounded bilateral subcortical frontoparietal hypodense zones peripheral contrast material enhancement. Pseudobulbar palsies and hemiparesis worsened and the patient required nasoenteral feeding. She was discharged after four months, with severe disabilities, with the diagnosis of Balo concentric, a progressive demyelinating disease.

This offcial docuemnt is statement of the President of the Chilean Nuclear Energy Commission, Dr. Eduardo Bobadilla, about the nuclear policy of the Chilean State, thanks to the international policy adopted by president Aylwin (1990-1994) and his succesor Frei Ruiz-Tagle (1994-) a nuclear development plan, protected by the Chilean entrance to the nuclear weapons non proliferation treaty and Thatelolco Denuclearization treaty, has started. Chile will be able to develop without interference, an autonomous nuclear electrical system and other pacific uses of nuclear energy. Chile also supports a new international treaty to ban nuclear weapon tests

Se presentan dos casos de pacientes con una siringomielia provocada por una aracnoiditis, en los que se les realizó una endomielografía intraoperatoria ayudando a confirmar la continuidad de la cavitación intramedular. En estos casos se discutía la comunicación de la siringomielia por los hallazgos de la resonancia magnética en que aparecían tabiques. Aparece como un procedimiento de bajo riesgo y utilizable en la mayor parte de los pabellones que tengan equipos de radioscopía

Vertebral artery dissection seems to be a frequent cause of stroke in young adults. We report a 34 years old female that suffered a cardiac arrest while practicing aerobics, with complete recovery and four months later developed an acute Wallenberg's syndrome. Magnetic resonance imaging showed an infarction in the right posterolateral medulla oblongata and in the right cerebellar hemisphere. Angiography revealed an occlusion of the third segment (V3) of the right vertebral artery which was hypoplastic. The patient was anticoagulated with a favorable clinical outcome. A follow up angiography, performed six months later, showed an incomplete recanalization of the vessel. Vertebral artery dissection should be suspected in every patient with ischemic symptoms or signs related to the vertebrobasilar territory, specially in young or middle aged patients with a history of trauma. Magnetic resonance imaging and ultrasound-doppler examinations are the diagnostic test of choice.
