Oculoauriculovertebral anomaly: segregation analysis.

Seventy-four families of probands with oculoauriculovertebral anomaly were evaluated, including 116 parents and 195 offspring. Relatives were examined to identify ear malformations, mandibular anomalies, and other craniofacial abnormalities. For segregation analysis using POINTER, selection of the sample was consistent with single ascertainment. Different population liabilities were used for probands and relatives, because affection was narrowly defined for probands and broadly defined for relatives. The hypothesis of no genetic transmission was rejected. The evidence favored autosomal dominant inheritance; recessive and polygenic models were not distinguishable.

Sister chromatid exchange analysis of human cells exposed to diagnostic levels of ultrasound.

Lymphocyte and lymphoblastoid cells were exposed in vitro to diagnostic levels of ultrasonic beams delivered by a Hewlett-Packard CE 30001 and a GE system with a 5 MHz linear transducer for 20 sec, 1 min, 5 min, and 20 min. Temperature and cavitation effects were controlled and there were matched sham exposures. The synergistic effects of theophylline with ultrasonography also were investigated. Small increases in sister chromatid exchange levels were observed after ultrasonic exposure, but increases were so small as to be unlikely to have clinical relevance. Theophylline was found to have no effect and ultrasonography had no effect on cell viability.
