A correlated laboratory and clinical study of pelvic infections has now been continuously pursued for many years. With this work as a basis, I present certain problems of surgical interest in the management of patients with inflammatory lesions of the pelvic viscera. SPECIAL FEATURES OF VAGINAL DISCHARGES A study of the bacteriology of chronic leukorrhea, first reported in 1914, revealed that the chief sources of infectious vaginal discharges are Skene's ducts and the uterine cervix.
