Some zoophiles and researchers draw a distinction between zoophilia and bestiality, using the former to describe the desire to form sexual relationships with animals, and the latter to describe the sex acts alone. Confusing the matter yet further, writing in 1962, Masters used the term bestialist specifically in his discussion of zoosadism.Stephanie LaFarge, an assistant professor of psychiatry at the New Jersey Medical School, and Director of Counseling at the ASPCA, writes that two groups can be distinguished: bestialists, who rape or abuse animals, and zoophiles, who form an emotional and sexual attachment to animals. Colin J. Williams and Martin Weinberg studied self-defined zoophiles via the internet and reported them as understanding the term zoophilia to involve concern for the animals welfare, pleasure, and consent, as distinct from the self-labelled zoophiles concept of "bestialists", whom the zoophiles in their study defined as focused on their own gratification. Williams and Weinberg also quoted a British newspaper saying that zoophilia is a term used by "apologists" for bestiality. Extent of occurrence
The Kinsey reports rated the percentage of people in the general population who had at least one sexual interaction with animals as 8% for males and 5.1% for females (1.5% for pre-adolescents and 3.6% for post-adolescents females), and claimed it was 40–50% for the rural population and even higher among individuals with lower educational status, but some later writers dispute the figures, because the study lacked a random sample in that it included a disproportionate number of prisoners, causing sampling bias.
These immature granulocytes are seen in peripheral blood smears. Diagnosis is confirmed when a bone marrow biopsy demonstrates significant replacement of the normal bone marrow compartment by fibrosis, malignancy or other infiltrative process. The presence of immature blood cell precursors helps distinguish another cause of pancytopenia, aplastic anemia, from myelophthisic anemia because in aplastic anemia the hematopoietic cells are damaged and immature blood cells are not seen in the peripheral blood. There may be evidence of extramedullary hematopoiesis (marrow elements can be found in the spleen, liver). Treatment
Treatment of this disorder involves treatment of the underlying cancer. See also
