Endodontic stabilizers.

With the recent influx of osseointegrated endosseous implants in dentistry, attention has been drawn away from using endodontic stabilizers as a means of stabilizing and retaining teeth. It is our opinion that endodontic stabilizers should be considered in the treatment planning of seemingly nonretainable teeth. They are biocompatible and have the additional advantage of maintaining the periodontal membrane attachment of the remaining tooth. Extraction and subsequent replacement with osseointegrated implants should only be considered after all other means of retaining the natural tooth have been fully explored. Selective case studies from various areas of the dentition demonstrate the broad applicability of stabilizers. A technique is presented for the use of endodontic stabilizers.

Familial variable immunodeficiency: autosomal dominant pattern of inheritance with variable expression of the defect(s).

In 1963, Rosen and Bougas reported the case of a woman with recurrent infection, marked elevation of 19S, and virtual absence of 7S gamma globulin. Recently, members of her family were found to have similar abnormalities: Ten of the 37 family members tested had elevated levels of serum IgM accompanied by a combined deficiency of IgG and IgA in three, and by a deficiency of either IgG or IgA in two. In five, an increase in IgM was the sole abnormality. Two children had deficiencies of IgG and IgA with normal serum levels of IgM. Ten of the 12 affected individuals had no IgD detectable by radial immunodiffusion and six had a low percentage of IgG-bearing B lymphocytes. A lack of correlation between the immunochemical abnormalities and either the presence or severity of clinical illness was observed. The presence of immunodeficiency in three generations and in both sexes of this family suggests an autosomal dominant mode of inheritance with variable penetrance of the defect.

Hypersensitivity pneumonitis.

Hypersensitivity pneumonitis, a disease caused by repetitive inhalation of nonviable organic dust, is increasingly recognized as a cause of acute and chronic lung disease in both children and adults. Twenty-one of 32 children and adults who went on a hay ride in Arkansas developed this disease. These cases are reported. The clinical manifestations, pathology, differential diagnosis, treatment, and immunologic aspects of the disease are reviewed.
