Intragastric balloons are associated with (1) early period intolerance, (2) diminished effect within 3-4 months, and (3) bowel obstruction risk mandating removal at 6 months. The introduction of an adjustable balloon could improve comfort and offer greater efficacy. A migration prevention function, safely enabling prolonged implantation, could improve efficacy and weight maintenance post-extrac...

Hallervorden-Spatz disease (HSD) is a rare autosomal-recessive hereditary disorder characterized by the early onset of progressive movement alterations, including dystonia, rigidity, choreoathetosis, and mental deterioration. HSD is also associated with a variety of psychiatric symptoms, primarily depression and mental deterioration. However, psychosis has rarely been reported as a major sympto...

The results of initial clinical nuclear magnetic resonance imaging of the brain in eight normal and 52 children with a wide variety of neurologic diseases were reviewed. The high level of gray-white matter contrast available with inversion-recovery sequences provided a basis for visualizing normal myelination as well as delays or deficits in this process. The appearances seen in cases of parenc...

Denis Diderot pensa o humano como equilíbrio instável recepção impressões sensoriais, do exterior interior, tomada decisão que ação, interior ext...

Neurological abnormalities associated with spiculated, "acanthocytic" red cells in blood have been summarized as neuroacanthocytosis. This is a heterogeneous group of conditions that can now be clearly subdivided on the basis of genetic discoveries. The core neuroacanthocytosis syndromes are autosomal recessive chorea-acanthocytosis (ChAc) and the X-linked McLeod syndrome (MLS). Huntington's di...

Huntington's original description of involuntary movements and dementia affecting certain families referred only to adults, although a juvenile or adolescent form (thought by some to be a separate clinical entity) has for long been associated with his name, despite attempts at reclassificaton. Myriantho-poulos (1966), for example, has suggested 'striato-cortical degeneration of children in fami...
