Angel-shaped phalanges in brachydactyly C: a case report, and speculation on pathogenesis
No full textWe describe a woman and her daughter affected by brachydactyly type C. The unusual feature in the child included the striking angel-shaped appearance of the proximal phalanges of the index and middle fingers of one hand, whereas more typical triangular epiphyses with elongation of their radial side were present at the same location in the opposite hand. It is suggested that this peculiar phalangeal configuration occurs as a transitory event in early or mid childhood in phalanges that are marked by severe ossification delay, which is most prominent at the level of the primary ossification centre

T1 relaxation maps allow differentiation between pathologic tissue subsets in relapsing-remitting and secondary progressive multiple sclerosis
No full textIn an attempt to clarify whether T1 relaxation time mapping may assist in characterizing the pathological brain tissue substrate of multiple sclerosis (MS), we compared the T1 relaxation times of lesions, areas of normal-appearing white matter (NAWM) located proximal to lesions, and areas of NAWM located distant from lesions in 12 patients with the relapsing-remitting and 12 with the secondary progressive (SP) subtype of disease. Nine healthy volunteers served as controls. Calculated mean T1 values were averaged across all patients within each clinical group, and comparisons were made by means of the Mann-Whitney U-test. Significant differences were found between all investigated brain regions within each clinical subgroup. Significant differences were also detected for each investigated brain region among clinical subgroups. While T1 values of NAWM were significantly higher in patients with SP disease than in normal white matter (NWM) of controls, no differences were detected when corresponding brain areas of patients with RR MS were compared with NWM of controls. T1 maps identify areas of the brain that are damaged to a different extent in patients with MS, and may be of help in monitoring disease progression
Coefficient D(av) is more sensitive than fractional anisotropy in monitoring progression of irreversible tissue damage in focal nonactive multiple sclerosis lesions
No full textPersistently hypointense lesions on T1-weighted MR images have been shown to correlate with the amount of axonal damage and clinical disability in multiple sclerosis (MS) patients. The purpose of this study was to investigate whether diffusion coefficient D(av) and fractional anisotropy (FA) are able to detect quantifiable differences among three groups of focal nonactive multiple sclerosis (MS) lesions that appear qualitatively different on T1-weighted images

No full textWe present a girl with short stature, growth hormone neurosecretory dysfunction, severe hypoplastic/aplastic changes of the bones of the hands and feet with dysharmonic ossification, severely delayed bone age, microcrania, and fibular hypoplasia. Parental consanguinity suggests autosomal recessive inheritance. An additional three cases [Eiken et al., 1984: Eur J Pediatr 141: 231-235] sharing some of the radiographic manifestations of this patient have been reported. However, distinctive findings in the present case seem to outline a separate entity
