1929. The title of the editorial in question is “A Medical Diagnostic Blind spot. ” The subject is often debated in pediatric literature but is seldom to be met with in dental journals because the dentist does not come in contact with the teething infant. The discussion as to whether ordinary dentition causes pathologic symptoms is very old and apparently aggravated greatly by a confusion of terms. Both factions may be right, for, if dentition is normal, there should be no marked symptoms beyond the slight local irritation, and if pathology develops, we can simply state that the ,,dentition is pathologic. The pathology in these cases consists chiefly of various reflexes not ordinarily seen in teething. If during dentition the infant develops some unusual malady, like convulsions, one should certainly take under advisement the possibility that the latter are of reflex origin. In such cases there should be either an unusual degree of nervous reactivity or some unusual local condition due to irregular development. No one doubts that in abnormal dentition in the older subject in connection, especially, with anomalous eruption of the third molars, many severe reflexes may develop including insomnia, reflex epilepsy, etc. The late Henry S. Upson, who wrote a monograph on this subject, left a fund for the study of dental reflex pathology, and up to 191’7 over 2000 cases had been found recorded in literature in which a connection was shown between dental disorders and nervous ailments. The editorial closes with the suggestion that a dentist may at times be called in to inspect teething children with symptoms possibly due to deniition. For one thing the possibility of a local infection should be excluded.

Chang and Feng, as a result of experiments on albino rats at the Peking Union Medical College, Peking, consider the thyroid secretion the most important factor controlling the growth of hair. They observed that by underfeeding these a.nimals they were able to retard the growth of hair. But if these underfed rats were given thyroid in proper doses, their hair m.ay grow at nearly normal rates, while if thyroid i.s given in excess, hair growth will be depressed. It is interesting to note that these investigators found that in normal animals the administration of thyroid may retard or depress the growth of hair.
