Localized perivascular demyelinization of the peripheral processes of cochlear neurons was observed in surface preparations of the osseous spiral lamina in two neonates, one a premature infant with erythroblastosis fetalis, the other a full-term infant with cyanotic congenital heart disease. In both cases the cause of the demyelinization was unknown. Both infants had severe edema as a result of congestive heart failure and anoxia. The serum bilirubin level in the erythroblastotic child appeared too low to have caused injury to the nerve fibers. The demyelinization was most striking in the lower half of the basal turn. It was observed only in the immediate vicinity of meandering stretches of capillaries as they crossed the nerve fibers. In the premature infant there was hair cell loss throughout the cochlea; in the other there was no hair cell loss, but a malformed labyrinth of the Mondini type.

Ameloblastomas are locally invasive benign tumors believed to originate from the developing dental lamina. Maxillary ameloblastomas are rare, comprising only 20% of all ameloblastomas. Of these, 90% arise posterior to the canine tooth. As tumors of the posterior maxilla grow slowly, symptoms are few until the tumor has reached considerable size. At the time of presentation there may be evidence of extension into anatomic areas adjacent to the posterior maxilla. Hemimaxillectomy through wide surgical exposure has the best chance of achieving tumor control. However, once the tumor has extended beyond the confines of the maxilla the prognosis for control of the disease is poor

The longitudinal consistency of personality characteristics over a period of 45 years is examined. The data are drawn from the Kelly Longitudinal Study, a panel involving an original group of 300 men and 300 women. Measures of emotional disturbance (from the Bell and Bernreuter inventories) during the 1930s and the 1950s had significant correlations in the .25-.40 range with measures of psychiatric symptoms (from the Cornell Medical Index) taken in 1979-1981. Revised inventory scales with content related to neuroticism and social introversion-extraversion had moderate longitudinal consistency across several decades of adult life and demonstrated convergent and discriminant validity. This study demonstrates the utility of personality measurements in predicting significant psychological outcomes over the full interval of the normal adult lifespan.

The surgeon, medical and nonmedical staff, and the reception, consultation, treatment, surgical, and recovery areas constitute the basic elements of the office operating room complex. In reality these elements are an inseparable dynamic unit; however, for the purpose of discussion they have been examined separately to study their particular aesthetic and nonaesthetic psychological contributions to outpatient surgery. Knowing why a patient forms certain attitudes about the doctor, the office staff, and the office or suite and having some insight into how a patient perceives these same elements are very important to the young practitioner of facial plastic surgery. It is possible that in the contemporary medical world where there are many surgeons of equal ability, success may depend on understanding these psychological aspects

Chondrosarcoma arising in the nasal septum has been previously described only 11 times. In this report, another case occurring in an 89-year-old man is discussed. The rarity of such a tumor arising in previously normal cartilage is emphasized. Prognostic factors and surgical treatment are discussed

The objective of this study was to explore the hypothesis that developing labyrinthine sensory receptors attract ingrowing neurites by chemotaxis. Cocultured otic explants which shared a single statoacoustic nerve (VIIIn) ganglion were explanted from 11-, 12.5-, and 14-day-old mouse embryos. Heterotypic ganglion explants consisted of 12-day-old otic explants which had their VIIIn replaced by a 10.5-day-old trigeminal nerve (Vn) ganglion. All cultures were grown to the equivalent of 20 days of gestation. Neurites of the (+) VIIIn explants grew into the sensory areas of both the (+) and (-) VIIIn cocultured explants. Neurites of the 14-day-old cocultured otic explants were only found in association with sensory areas within the (+) VIIIn explant. Neurites of nerve V of the heterotypic ganglion explants were found in association with the sensory areas of these otic explants. These results support the hypothesis that a limited period of chemotaxis (nonspecific in nature) is a possible mechanism for the establishment of the pattern of neurite ingrowth to the areas of the inner ear sensory receptors.

A Norton metal endotracheal tube with a Merav parachute cuff cemented to the distal end has solved many of the problems involved in administration of anesthesia for laser surgery of the upper aerodigestive tract. The tube is fireproof and provides an air-tight seal for positive pressure ventilation without the impediment of a cuff channel. It is ideal for laser surgery of the oral cavity and pharynx and may be used effectively for glottic lesions in many instances
