Relationship of self-concept, health locus of control, and perceived cancer treatment options to the practice of breast self-examination.

Breast cancer remains one of the most prevalent forms of cancer for women in the United States. Recognition of the fact that no more than 40% of women practice breast self-exam (BSE) is of major concern in that BSE has been identified as one method of early detection. The factors that encourage or discourage women to perform BSE need to be identified. The current study investigated the relationships between women's practice of BSE, self-concept, locus of control, and knowledge of treatment options for breast cancer. One mammogram screening center provided the 235 subjects who completed the questionnaires. Subjects who practiced BSE more frequently had a slightly higher self-concept score and were more aware of breast cancer treatment options (r = 0.16, p less than 0.05). Weak correlations were found between chance locus of control and BSE frequency of practice (r = 0.22, p less than 0.05). The majority of subjects reported irregular BSE practice, both as to whether they practiced BSE on a monthly basis and as to the time of the month for BSE.

An overview of serological tests currently available for laboratory diagnosis of parasitic infections.

Current methods and commercial test systems for the diagnosis of parasitic infections in both animals and humans are reviewed. Lists of test kits and their manufacturers are provided along with ordering information: the only commercially available test kits are for the diagnosis of toxoplasmosis in humans or animals and dirofilariasis (heartworm) in dogs. A partial list of diagnostic laboratories and the parasite tests they perform is also provided. Complete lists of diagnostic tests that could be obtained in the private sector are not available but would be useful. Two microfluorometric solid-phase assay systems are reviewed, and adaptations to custom assays for several kinds of parasites are briefly described. User problems in performing tests and interpreting results are stressed with emphasis placed on diagnosis of dirofilariasis in dogs. False-positive serology in dogs without heartworms and negative antibody responses in micro-filariae-positive animals are discussed with respect to proper interpretation of results.

Cytauxzoonosis in domestic cats: report of two cases in Oklahoma, with a review and discussion of the disease.

In 2 cases of cytauxzoonosis in domestic cats in Oklahoma, the clinical features, gross lesions, and microscopic findings were of similar nature and degree to those previously reported by others, both in the naturally occurring and experimentally induced disease. Intraerythrocytic forms of Cytauxzoon felis organisms were demonstrated in stained blood smears from one cat. Blood from the other cat was not examined. The diagnosis was established by the finding of schizonts in endothelial-associated macrophages within vascular channels in tissues from both cats.

Cytauxzoonosis in bobcats.

Blood from 4 wild-trapped bobcats (Lynx rufus rufus) with naturally occurring infection by an intraerythrocytic piroplasm morphologically indistinguishable from the piroplasm form of Cytauxzoon felis was inoculated parenterally into domestic cats. None of the bobcats had signs of disease at the time of capture or subsequently, but all remained parasitemic. Erythroparasitemia developed in all 4 of the domestic cats inoculated with parasitemic bobcat blood. One of the domestic cats later died and had gross and histologic lesions characteristic of those reported in naturally occurring and experimentally induced fatal cytauxzoonosis of domestic cats. The other 3 cats remained parasitemic but otherwise appeared healthy. One of these cats was subsequently inoculated with virulent Cytauxzoon of domestic cat origin and it died within 14 days. Two of the bobcats, including the one whose blood induced fatal cytauxzoonosis in the domestic cat, were similarly inoculated but remained without apparent ill effects. Schizogenous tissue forms of Cytauxzoon organisms were not found in tissues from any of the 4 bobcats or in tissues from the 2 parasitemic domestic cats that were not inoculated with the virulent organism. The results demonstrated that the bobcat is a natural host for the organism that causes fatal cytauxzoonosis in domestic cats and provides presumptive evidence that the naturally occurring bobcat piroplasm may be the intraerythrocytic form of C felis.

Cytauxzoon-like piroplasms in erythrocytes of wild-trapped bobcats in Oklahoma.

Stained blood smears from 26 bobcats wildtrapped in 4 Oklahoma counties were examined for protozoan parasites. A Cytauxzoon-like piroplasm was observed in erythrocytes from 13 of 21 bobcats trapped in 2 counties. Organisms were not observed in the 5 bobcats trapped in 2 other counties. The degree of parasitemia varied from less than 0.5% to 5% infected erythrocytes but commonly ranged from 1% to 3%. Responding anemia was apparent in 1 of the 13 infected bobcats but other ill effects possibly attributable to the parasite were not observed. Whether the organism is Cytauxzoon felis or is a species of Babesia is discussed but remains speculative.
