CT-Cephalometry—A study in Indian population

Determination of obstructive site in obstructive sleep apnoea (OSA) is of paramount importance is planning the management. Cephalometric evaluation of lateral X-rays when combined with clinical assessment and fibreoptic examination of the airway helps in locating the site of obstruction. The usual technique of cephalometry has been modified so as to give a better delineation of the soft tissues. Holding a 2mm card board in the mouth and using barium paste helped in more accurate calculations. Using our technique, various parameters have been quantified and a number of controls were studied and normal range derived. Further improvement in cephalometry has been done by using C.T. cephlometry topogram technique. A topogram is a scan done on a running table top cranio-caudally. Using the topogram technique 38 OSA patients were evaluated for all the parameters. The technique, its advantages over traditional cephalometry and the values obtained in the study are discussed in this paper.

Cell-mediated immunity in rheumatic diseases

Lymphocyte responses to phytohemagglutinin, concanavalin A, and pokeweed mitogen were tested in normal patients and in patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), scleroderma (PSS), other connective tissue disease, and other illnesses. The relationship of lymphocyte response to diagnosis, therapy, and T- and B-lymphocyte populations was analyzed. Additional studies included the determination of proliferative responses of various combinations of purified T and B lymphocytes cultured with plant mitogens. Lymphocytes from patients with RA and SLE incorporated significantly less thymidine in the presence of plant mitogens as compared to normal and comparably ill subjects. Treatment had no effect on mitogen response. Responses to all three mitogens correlated closely in patients with RA, SLE, or PSS; no correlation was noted between the response to mitogen of lymphocytes in culture and the number of T cell ultured.
