“…In 1965, Lejeune et al 1965 suggested a tandem inverse duplication in these patients. Subsequently, a few cases have been published [Turleau et al, 1980; Pfeiffer and Loidl, 1982; Stoll et al, 1982; Pangalos et al, 1992b; Gutierrez‐Angulo et al, 1999; Barbi et al, 2000; Cortes‐Gutierrez et al, 2002; Wandall et al, 2002; Sheth et al, 2007; Egashira et al, 2008]. In this study, we report on a DS child with karyotype 46,XX,idic(21)(q22.3).…”

Objective. To investigate whether structural changes are present in the cortical and subcortical gray matter of the brains of patients with rheumatoid arthritis (RA).Methods. We used two surface-based style morphometry analysis programs and a voxel-based style analysis program to compare high-resolution structural magnetic resonance imaging data obtained for 31 RA patients and 25 age-and sex-matched healthy control subjects.Results. We observed an increase in gray matter content in the basal ganglia of RA patients, mainly in the nucleus accumbens and caudate nucleus. There were no differences in the cortical gray matter. Moreover, patients had a smaller intracranial volume.Conclusion. Our results suggest that RA is associated with changes in the subcortical gray matter rather than with cortical gray matter atrophy. Since the basal ganglia play an important role in motor control as well as in pain processing and in modulating behavior in response to aversive stimuli, we suggest that these changes may result from altered motor control or prolonged pain processing. The differences in brain volume may reflect either generalized atrophy or differences in brain development.
