Fahr syndrome is a rare anatomo-clinical entity in pediatrics. Associating calcifications of the basal ganglia with phospho-calcium metabolism disorders, most often resulting neuropsychiatric symptoms. In our study, discovery this two patients was fortuitous thanks to typical radiological appearance, associated clinical picture they initially presented, hence interest brain imaging diagnosis sy...

Thirty-eight cases of basal ganglia calcification imaged on computed axial tomography were reviewed. Most cases were felt to represent senescent calcification. The possibility of a vascular aetiology in this group is discussed. A less common group of patients was identified with calcification secondary to abnormalities in calcium metabolism or radiation therapy. Three cases of basal ganglia cal...

Yet cold does not bring about a large increase in activity of the thyroid since a sojourn of three weeks in a refrigerator at 2 to 4 degrees centigrade increases the b...
