  • Title: Distribution and extent of schistosomiasis in female pelvic organs, with special reference to the genital tract, as determined at autopsy.
    Author: Gelfand M, Ross MD, Blair DM, Weber MC.
    Journal: Am J Trop Med Hyg; 1971 Nov; 20(6):846-9. PubMed ID: 5131693.
    Abstract:
    Tissue samples were taken in a series of 64 consecutive autopsies of African women aged 16-70 years. These were block-dissected and studied to determine the frequency of schistosome eggs in tissues of the uterus, and its adnexa, and in the vagina, as well as to determine the numbers of eggs in these tissues. In addition, by histological examination, it was hoped that the frequency and degree of inflammation accompanying the eggs' presence could be learned. 37 of 64 autopsy specimens showed evidence of schistosomiasis. In terms of the mean number of eggs per gram of tissue, the heaviest deposition of eggs was in the bladder. The cervix, uteri, fallopian tubes, and ovaries had eggs to much the same degree, leaving the myometrium and parametrium with the fewest eggs resident. Rectal tissue was relatively clean, surprizingly. Tissues of pelvic organs were positive for schistosome eggs in a total of 37: 33 by digestion technique, 24 by histology, and 20 by both. Inflammatory changes associated with schistosome eggs were found in 12 of 24 infections discovered histologically. Inflammation in the gential tract was only found in 3 cervixes and 2 vaginal walls; in bladders for example, infectious inflammation was seen in 7. Eggs of S. haematobium were identified in 19 of 24 histologically discovered infections. Eggs of S. haematobium were found in all 33 instances identified by the digestion technique, and in 9 of these instances, eggs of S. mansoni were also found. 7 of 9 infections with S. mansoni were of the rectum and 2 were of the bladder.
