Prenatal detection of de novo paracentric inversion 46, XX inv (14) (q22q32.1) in a normal child: report and review of the literature.

We present prenatal diagnosis and follow-up examination of an individual with a de novo paracentric inversion of the long are of chromosome 14. A literature search documented 19 other cases of paracentric inversion of 14q. The outcome of each of these cases is specified together with that of this current case. Four of the 20 cases, all XY, manifested significant abnormalities with mental retardation and microcephaly present in 3 of the 4 cases; 15% (2/13) of familial cases had abnormalities and 40% (2/5) of de novo cases had abnormalities.

Numerical simulation of steady flow in a model of the aortic bifurcation.

The governing equations of steady flow of an incompressible viscous fluid through a 3-D model of the aortic bifurcation are solved with the finite element method. The effect of Reynolds number on the flow was studied for a range including the physiological values (200 < or = Re < or = 1600). The symmetrical bifurcation, with a branch angle of 70 degrees and an area ratio of 0.8, includes a tapered transition zone. Secondary flows induced by the tube curvature are observed in the daughter tubes. Transverse currents in the transition zone are generated by the combined effect of diverging and converging walls. Flow separation depends on both the Reynolds number and the inlet wall shear.

Creativity in medical genetics and dysmorphology.

One gauge of creativity in medical genetics and dysmorphology is the eponym. Conditions named for people reflect their powers of observation and analysis. We examined the fields and ages of 210 eponymous physicians and scientists whose biographies were published by Peter and Greta Beighton [1986] in The Man Behind the Syndrome. Twenty fields were represented with the dominant fields being, in order, pediatrics, neurology, general and internal medicine, pathology, radiology, and orthopedics. The ages of the eponymous workers averaged 43 years at the time of their relevant publications. Fully a fifth of the contributions were made by persons aged 30 years or less, or 60 years or more, suggesting that eponymous fame may come to workers of talent independent of age.
