Macromastia in adolescence.

Macromastia is a deforming, disabling, and painful condition, especially in the adolescent. Multiple procedures have been advocated and are successful for the reduction of breast tissue. In addition, adjunctive therapy with hormones may prevent relapse. The hormonal influences on breast development and the etiology of macromastia remain complex and not well understood. It is safe to surmise that the pathologic condition is multifactorial, with both inherited and acquired aspects. In the various techniques for reduction, it is important to have a clear understanding of vascular and neural innervation of the breast in order to maintain maximum security in reduction without loss of excessive vital tissue. Although both sensory ability and lactation function are diminished with most procedures and eliminated with some, careful planning and patient counseling in all cases should lead to maximal benefit and optimal results.

Use of low intensity roentgen ray imaging for determination of tube and catheter placement in the young primate: implication for use of the Lixiscope in the surgical neonate.

The new technology of low intensity roentgen ray imaging offers promise in rapid bedside location of tube and catheter placement in the surgical neonate. Using the Lixiscope we have been able to accurately detect in an animal model the exact location of various tubes and catheters used routinely in pre and postoperative neonatal care. Minimal training is required to be able to use the device. We think the Lixiscope offers detection of the positions of standard tubes and catheters with increased speed, as well as a reduction in the radiation exposure for patients and staff in the neonatal unit.
