Focal facial inflammation of the attached gingiva.

An unusual gingivitis noted as a discrete lesion involving the facial attached gingiva in a focal and confined area has been described in two adolescent females. A unique histopathologic appearance includes a striking intraepithelial edema associated with a focal area of acute and chronic inflammation. Inconclusive immunologic study of one patient indicated an epithelial-connective tissue immune complex deposition suggestive of but not typical of that seen in pemphigoid.

Clinical and laboratory studies on human sclera allografts.

In the first section of this two-part report human peripheral blood leukocytes were tested for reactivity to extracts of sclera. Absence of scleral antigenicity is suggested by the results which showed that the leukocytes reacted similarly in sclera stimulated cultures and in the controls. The second part of the report discusses the clinical aspects of sclera allografts and provides guidelines for their clinical use.
