Mixed sclerosing dysplasia of the bone associated with ovarian and skin problems.

The clinical, radiologic, histopathologic, and genetic features of a sclerosing bone dysplasia found in three members of a family are described. The bone disorder affected all metaphyseal-diaphyseal regions of all long bones, the skull, and three metacarpals. All affected members also had ichthyosis vulgaris and premature ovarian failure. These features have not been reported before, indicating a new syndrome.

Patellectomy with vastus medialis obliquus advancement for comminuted patellar fractures: a prospective randomised trial.

We have compared the results of simple patellectomy (group A, n = 16) and patellectomy with advancement of the vastus medialis obliquus (group B, n = 12) in a prospective, randomised trial, with a minimum follow-up of three years. The results in group B were significantly better (p < 0.001) than those in group A. Although the patella should be preserved if possible, we advocate advancement of the vastus medialis obliquus when patellectomy is necessary.

SEP spectral analysis of cholesterol rich rats.

In this study, twenty four albino rats, weighing between 180 and 200 g were tested. One half was fed with a diet containing 1% cholesterol for 12 weeks and the other half was fed with a normal lab diet for the same period. After the experimental period, the plasma cholesterol level in the diet group was 134.04 +/- 21.11 mg/dl compared with the control group 72.72 +/- 10.5 mg/dl. In the two groups, SEPs were recorded from central (Cz) referenced to frontal (Fz) following left posterior tibial nerve (PTN) stimulation. Amplitude spectra of SEPs were computed by Fast Fourier Transform (FFT) algorithm. Their amplitude maxima were found to occupy the frequency bands of 1-3.5, 4-5, 6-7, 8-10, 11-12, 13-20, 20.5-36 and 36 Hz and above. The decibel (dB) values of the maxima were statistically lower for hypercholesterolemia than for the normals in the all the frequency bands.
