Dental observations in Gaucher's disease: review of the literature and two case reports with 13- and 60-year follow-ups.

Gaucher's disease is a genetically determined inborn error of metabolism in which acid beta-glucosidase or one of its cofactors is absent or diminished in macrophage cells and cause an accumulation of glucosylceramide in these cells. These Gaucher cells accumulate in the organs of the reticuloendothelial system and cause varying degrees of splenomegaly, hepatomegaly, and encroachment of the marrow cavity of bones. Dental radiographs often reveal consistent bony changes that result from this encroachment. In cases where visceral signs are not apparent, dental radiographs can detect the presence of the disease. Because therapy is available, early recognition of this disorder may reduce overall morbidity. A review of the dental radiographic changes over as many as 60 years shows the effects of oral surgery procedures on bone degeneration and regeneration. The effects of mannose lectin acid beta-glucosidase, alglucerase on bone deposition are discussed. Finally, a literature review shows that the changes in the dental radiograph of patients with Gaucher's disease are very specific. Currently, this disorder and its associated molecular genetics are a prototype for research of new treatments such as allogenic bone marrow transplantation and molecularly engineered enzymes.

Dissociated perception of a visual defect.

A case of amaurosis in the right eye with a left homonymous hemianopsia and right superior quadrantanopsia is reviewed. There was marked dissociation in the patient's perception of his visual defects. The concepts of denial as presented in the literature were reviewed. The lack of denial in children was discussed in association with hemispheric specialization. Denial of a neurological deficit may be the result of improper arbitration of information between the two cerebral hemispheres.

Multiple personality, seizure disorder, and the electroencephalogram.

The electroencephalogram (EEG) in a case of multiple personality was described. Despite conflicting reports in the literature we found no changes in the EEG which could not be ascribed to the normal changes seen in transitions from various states of alertness. The problems of differentiating multiple personality as a psychiatric entity in itself from those cases arising as a result of chronic partial or partial-complex epilepsy are discussed. Further research with more sophisticated electrophysiological data acquisition and data reduction equipment is suggested.
