The development of techniques for studying sex chromatin from oral mucosa (Moore and Barr, 1955; Marberger at al., 1955), and chromosomes from peripheral blood (Moorhead et al., 1960), has made it possible to undertake population surveys to identify individuals with abnormal sex chromosomes. The present knowledge of psychiatric effects of the sex chromosome abnormalities has been derived mainly from comparing their frequency in the psychiatric population with that in the general population.

The frequency of sex chromatin-positive nuclei during the first 7 days of life was determined in oral mucosa smears stained with lactic acetic orcein in three groups of newborn female infants: 28 cases of full-term newborns, 17 cases of infants with low birth weight (less than 2,000 gm) and high gestational age (more than 32 weeks), and 11 cases of infants with low birth weight and low gestational age (32 weeks or less). A transient suppression of sex chromatin frequency was observed for the first 3 days of life in the full-term females, as has been reported by previous workers. The infants with low birth weight and high gestational age likewise showed transient suppression. The infants with low birth weight and low gestational age, on the other hand, exhibited no comparable suppression of sex chromatin. The findings suggest that the mechanism responsible for sex chromatin suppression is related to a physiologic process that develops in the last 8 weeks of gestation.

A New Technique

A new technique for determining sex by detection of characteristic chromosomal material in nuclei of human tissues is described. Previous methods have employed skin biopsy and examination of the neutrophils in a blood smear. The present technique employs examination of cells obtained by scrapings from the oral mucosa. The technique has the advantage of the ready availability of the cells to be examined and the easier identification of the sex chromatin in the large mucosal cells by relatively inexperienced observers. Furthermore repeat examinations can be made without the trauma of a skin biopsy. The accuracy of the method compares favorably with those previously described.

Connective Tissue Stroma

The differentiation and maintenance of many specialized epithelial structures are dependent on the underlying connective tissue stroma and on an intact basal lamina. These requirements are especially stringent in the development and maintenance of the skin and oral mucosa. The keratinization patterns of thin or thick cornified layers as well as the appearance of specialized functional derivatives such as hair and teeth can be correlated with the specific source of stroma which supports these differentiated expressions.

A Current

Administrators of programs for children with communicative disorders in 11 midwestern states were surveyed to assess trends in the training and utilization of paraprofessionals. Topics included: (a) current trends in employment, (b) paraprofessional training, (c) use of ASHA and state guidelines, and (d) district policies for supervision. Selection criteria, use of job descriptions, training programs, and supervision practices and policies were examined. Results indicate that paraprofessionals are used but that standards for training and supervision are not consistently applied across all programs. Program administrators report minimal training for supervising professionals.
