Abstract: Cell-mediated and humoral immune responses were assessed in 50 patients with oral submucous fibrosis (OSMF) and the results were compared with those of 50 patients with oral-leukoplakia, 50 oral cancer patients, and 50 normal healthy adult controls. The number of high-affinity rosette-forming cells (HARFC) was found to be significantly decreased in OSMF and oral cancer, whereas the number of total rosette-forming cells (TRFC) remained unaltered. Levels of serum IgA, IgD, and IgE were found to be elevated both in OSMF and oral cancer. Immunologic derangements were found to be more pronounced in oral cancer than in OSMF. The enumeration of HARFC along with the estimation of serum levels of IgA, IgD, and IgE indicates that OSMF can be an intermediary stage in the malignant transformation of a normal cell, and that these parameters may serve as markers for the early detection of oral cancer.

Abstract: A newborn with paraplegia and evidence of a subarachnoid hemorrhage was found to have a spinal arteriovenous malformation. The arteriovenous malformation was managed by direct surgical obliteration. This patient is the youngest ever reported to have this disorder and the youngest so treated.

Abstract: The reported incidence of peptic ulcer disease (PUD) in patients with rheumatoid arthritis (RA) is higher than that of the general population. Unusual susceptibility to PUD in RA, independent of therapy, has been suggested. To compare RA patients with others who had similar drug exposure but no known predisposition to PUD, 120 patients hospitalized for treatment of severe arthritis (65 with RA, 55 with osteoarthritis) were assessed by questionnaire for PUD history, drug history and other relevant variables. The relationship of PUD to sex distribution, smoking, alcohol consumption and anti-inflammatory therapy followed expected patterns. We found high but similar PUD rates in RA and osteoarthritis (OA) patients (RA 15%, OA 18%). This suggests that a common factor (probably drugs) is responsible. We feel that the documented high incidence of PUD in RA is most probably related to drug therapy. Available methods cannot determine if PUD ever occurs as a primary manifestation of RA.
