External resorption presenting as an intracoronal radiolucent lesion in a pre-eruptive tooth.

A large intracoronal radiolucent lesion in an unerupted permanent molar was found during the routine assessment of a young male Caucasian prior to orthodontic treatment. The tooth was extracted. Histological examination indicated the lesion was caused by external resorption. The defect extended widely into the enamel and dentine, and was repaired in part by bone. The pulp chamber was not involved. The aetiology of these lesions is often obscure but in this case it appeared to have originated in the floor of two developmental pits on the occlusal surface of the tooth.

Some bacteraemias encountered in hospital practice.

This is a retrospective study of the results of 4,642 blood cultures taken from 2,190 patients from 1960 to 1967 in one London hospital. The results suggested that an increased incidence of bacteraemias at this particular hospital was mainly due to the increase in the number of patients having blood cultures. Some of the bacteraemias were terminal or transient and probably of doubtful clinical significance.

An epidemiological study of haemagglutination in hepatitis.

An epidemiological study of 36 U.S. Marines living in a barracks and exposed to infectious hepatitis was made, and the ability of their sera to agglutinate day-old chick erythrocytes was found to be abnormally high in 52.8% of the group. The other groups of American Servicemen similarly exposed showed no such deviation from the normally expected incidence of raised titres. An unexplained, abnormally high incidence of raised titres was found in several control groups. The titres appeared to be unaffected to any significant degree by gamma globulin prophylaxis or yellow fever immunization.
