RESUMEN
Seven patients with craniosynostosis (mean age 8 years, Apert syndrome, n = 4, Crouzon's disease, n = 3) underwent lengthening of the skull by gradual bone distraction. Three patients (group A) were treated by coronal craniectomy reaching the orbital fissure and gradual bone distraction. The other four (group B) underwent monobloc craniofacial disjunction and gradual bone distraction. The patients' progress was monitored clinically as well as by radiographs and photographs. The results showed that craniofacial disjunction followed by gradual bone distraction produced complete correction of exophthalmus and an improvement in the functional and aesthetic aspects of the middle third of the face without the need for bone grafts.

PIP: 9 M sulfuric acid spray reagent was found to be particularly suitable for differentiating natural estrogens from diethylstilbestrol in both a mixture of natural steroids and in biologic preparations under daylight as well as ultraviolet light. The method described is useful in analyzing animal feed and meat for human consumption and solves the problem of isolating estrone from diethylstilbestrol by giving different colors to the 2 compounds: under natural light, estrone shows an orange yellow color, while diethylstilbestrol appears dark gray; under ultraviolet light, the colors are lemon yellow and violet, respectively.^ieng
