Case report of a primary cystic sarcoma of the kidney, demonstrating fibrohistiocytic, osteoid, and cartilaginous components (malignant mesenchymoma).

The first case of a primary, cystic sarcoma of the kidney, containing fibrohistiocytic, osteoid, and cartilaginous elements (malignant mesenchymoma) is reported. The neoplasm occurred in a 29-year-old white woman, who had a right upper quadrant mass at least four years prior to presentation. Light and electron microscopy findings are presented. A 14-month follow-up revealed an extensive tumor recurrence in the right perirenal area with no apparent metastastic disease.

Studies of introital colonization in women with recurrent urinary infections. II. A comparison of growth in normal vaginal fluid of common versus uncommon serogroups of Escherichia coli.

Vaginal fluid collected from volunteers who denied a history of urinary infections was bactericidal to Escherichia coli at pH 4.0. When the pH was increased to 6.5 with sodium hydroxide, the same vaginal fluids supported bacterial growth. If vaginal fluid was adjusted at pH increments between 4.0 and 5.0, and inoculated with common and uncommon serogroups of Escherichia coli, the uncommon O-groups that never cause urinary infections were significantly (p less than 0.005) more inhibited by the lower vaginal pH than were the common O-groups of Escherichia coli.
