Sjögren-type syndrome after allogeneic bone-marrow transplantation.

Four patients, treated for hematologic disorders with bone-marrow transplants from HLA-identical siblings, spontaneously complained of dry eyes 8 to 12 months after transplantation. Four allograft recipients and two recipients of autologous bone-marrow transplants were evaluated for xerophthalmia and xerostomia. Three allogeneic marrow recipients had evidence of keratoconjunctivitis sicca, and two had decreased parotid gland function. All four allograft recipients had minor salivary gland histopathology identical to that of Sjögren's syndrome. The severity of symptoms and histologic lesions corresponded with the severity of chronic graft-versus-host disease. In addition, one patient developed sclerodermatous skin changes, another had discoid lupus erythematosus, and two patients had laboratory evidence of cholestasis. None of the patients had autoantibodies but all had hypergammaglobulinemia. In contrast, none of the recipients of autologous bone marrow had clinical, laboratory, or histologic findings resembling Sjögren's syndrome.

Effects of lavage techniques with third molar surgery.

A comparison study of 206 mandibular third-molar surgical sites, half of which were irrigated with high volumes of isotonic normal saline solution with a conventional hand syringe and half of which were irrigated with high volumes of isotonic normal saline solution by means of a mechanical pulsating lavage instrument, revealed the following: 1. No cases of localized osteitis occurred with the use of mechanical irrigation in 103 surgical sites (0%). 2. One case of localized osteitis occurred with regular irrigation in 103 surgical sites (0.97%). 3. The over-all incidence of localized osteitis was one case in 206 surgical sites (0.49%). 4. One case of infection occurred with mechanical lavage (0.97%). 5. Two cases of infection occurred with conventional lavage (1.96%). 6. The over-all incidence of infection was three cases in 206 surgical sites (1.45%). 7. No significant differences occurred at the 0.95 level of confidence when the two groups' 3- and 5-day healing were compared. 8. A fairly even distribution of postoperative infections and/or localized osteitis was noted among the cases handled by the three surgeons directly involved in the performance of the operations. 9. Three hundred fifty milliliters of isotonic normal saline solution under pressure (whether electrical or conventional) appreciably reduced the reported incidence of localized osteitis without the use of antibiotics. 10. The mechanical irrigator was less cumbersome and faster (30 seconds for 350 ml.) than the conventional hand syringe (4 to 5 minutes for 350 ml.). 11. The sterilization procedure was more complicated for the mechanical irrigator (gas autoclave) than for the conventional hand syringe (presterilized disposable type). 12. Loose (unattached) soft tissue and bony spicules were thoroughly removed by 350 ml. of irrigation.
