Tantalum implants as markers for evaluating postoperative orthognathic surgical changes.
The stability of sagittal split osteotomy advancements is not always 100% predictable. Assessment of postsurgical changes has historically relied on clinical evaluation of dental changes and superimposition of serial cephalograms, both of which have been shown to have serious drawbacks. A technique that improves the analysis of postsurgical changes is described in this paper; tantalum pin implants are placed in the osteotomized segments of patients undergoing surgical advancements. Implants eliminate many of the problems (orthodontic, growth, and remodeling changes) related to superimposition of presurgical and postsurgical cephalograms. Using this technique, surgical changes can be precisely analyzed, and the contribution of each factor of postsurgical relapse can be determined. This information, concerning the magnitude and direction of postsurgical changes, aids in following an individual's progress and increases the accuracy of large group studies by eliminating sources of variability in radiographic and clinical interpretation.

The prevalence of attentional problems and the effect of methylphenidate in children with myelomenigocele.
The prevalence of attentional problems, and the effect of methylphenidate was evaluated in a clinic population of children with myelomeningocele. Families of 79 children between the ages of 6 and 15 years were screened for the presence of attention problems in their children, using Conners' questionnaires for parents and teachers, and/or the DSM-IV checklist. Thirty-nine per cent of the children exhibited attention problems, primarily without hyperactivity. Fourteen children with attentional problems were enrolled in a double-blind placebo-controlled trial methylphenidate. Response to methylphenidate was assessed with Conners' questionnaires, Conners' Continuous Performance Test, and a battery of selected neuropsychological tests. No statistically significant response was measured for the group while on methylphenidate. Four children were clinical responders to methylphenidate. The prevalence of attentional problems in children with myelomeningocele is high, and effective medication therapy needs to be studied further.

Genital prolapse in a preterm female infant.
Genital prolapse in the female infant during the neonatal period is relatively rare and is usually associated with anomalies of the central nervous system. A case of vaginal prolapse in a small-for-gestational-age preterm female infant, without any associated nervous system anomalies, is presented. The clinical presentation, diagnostic approach, management, and outcome of the case are discussed with reference to a review of the literature.
