Osteomyelitis of the maxilla in the newborn

A case of osteomyelitis of the maxilla in a healthy infant is presented, the etiology of which seems to have been an upper respiratory tract infection. There was no evidence of lowered resistance and immunologic studies did not reveal any abnormality. Lincomycin seems to be the antibiotic drug of choice. In the present case, it was used, effectively, in conjunction with other antibiotics and surgical drainage.

Localized hyperplastic lesions of the gingiva: a clinicopathological study of 302 lesions

A study was made of a series of 302 consecutive cases of localized hyperplastic lesions of the gingiva (epulides). The lesions were classified into five groups: pyogenic granuloma, calcifying fibroblastic granuloma, fibrous hyperplasia, peripheral giant cell granuloma and denture hyperplasia. The study indicates that there are some differences in age and sex distribution as well as in location between the different histological groups. Pyogenic granuloma was found to be the most common lesion on the gingiva. Pyogenic granuloma and calcifying fibroblastic granuloma occur in younger patients more often than fibrous hyperplasia, and thus may represent a stage in the development of fibrous hyperplasia. Denture hyperplasia occurs predominantly in females and it is suggested that its formation may be affected by hormonal alterations in the menopause.

The maxillary sinus: a surgical approach via a gingivomucoperiosteal flap

The classic surgical approach to the maxillary sinus described originally by Caldwell and Luc, which is still very much in use, calls for an incision in the upper part of the buccal vestibulum. This incision has many disadvantages. A surgical technique that uses the full-thickness gingivomucoperiosteal flap avoids these disadvantages. This method was used in 74 cases during the last three years,and the results have been most satisfactory.

Ultrastructural study of focal epithelial hyperplasia

Biopsy material from two young Israeli patients with focal epithelial hyperplasia revealed acanthosis, papillomatosis, and the presence of many epithelial cells with a clear cytoplasm in the basale and stratum spinosum. Many of the inclusions seen with the electron microscope had the morphologic appearance of lysosomes, but definite identification must await cytochemical evidence.
