Puerperal ultrasonic hysterography

Ultrasonic hysterography was performed in 104 patients, between the 2nd and 5th postpartum day. An unexpectedly high number of women (16%) exhibited an abnormal uterine configuration. The ultrasonic diagnoses were compared to the results of previous investigations of the uterine configuration, if available.

Diet and cancer prevention: the fiber first diet

Diet can play a major role in cancer prevention. The international differences in cancer incidence are largely accounted for by lifestyle practices that include nutrition, exercise, and alcohol and tobacco use. About 50% of cancer incidence and 35% of cancer mortality in the U.S., represented by cancers of the breast, prostate, pancreas, ovary, endometrium, and colon, are associated with Western dietary habits. Cancer of the stomach, currently a major disease in the Far East, relates to distinct, specific nutritional elements such as excessive salt intake. For these cancers, information is available on possible initiating genotoxic factors, promoting elements, and prophylactic agents. In general, the typical diet in the United States contains low levels of the potent carcinogenic agents, heterocyclic amines, formed during the cooking of meats. It provides only about half the potent appropriate fiber intake and is high in calories. About twice as many calories as would be desirable come from fat, certain kinds of which enhance the development of cancers. Other foods with functional properties, such as soy products and tea, can be beneficial. To achieve reduction in risk of certain cancers, diet must be optimized, primarily to reduce caloric intake and the fat component. The latter should be 20% or less of total caloric intake and fiber should be increased to 25- 35 g per day for adults. One approach to achieving these goals is the Fiber First Diet, a diet designed around adequate fiber intake from grains, especially cereals, vegetables, legumes, and fruits, which thereby reduces both calorie and fat intake. Such dietary improvements will not only reduce cancer and other chronic disease risks, but will contribute to a healthy life to an advanced age. A corollary benefit is a lower cost of medical care.

Muscle necrosis in the extremities: evaluation with Tc-99m pyrophosphate scanning--a retrospective review

A retrospective review was done of 34 extremities studied between 1981 and 1985 with technetium-99m pyrophosphate scanning; 22 were subsequently amputated. Results of detailed pathologic examination or immediate postoperative examination of the resected extremity were available in 16 cases. In these cases, scanning had allowed correct prediction of the level of amputation and of the specific areas of muscle infarction in 13 cases. In the one case in which amputation was performed for infection rather than muscle necrosis, the lack of necrosis was correctly predicted with the scan. The limited results of this study indicate that the Tc-99m pyrophosphate scan allows the location of necrotic muscle to be predicted accurately and may therefore be a useful adjunct in determining the best level for ultimate amputation. Special caution is required in those cases in which muscle necrosis is due to acute causes (e.g., traumatic thrombosis) rather than chronic vascular disease.     

Expression and immunogenicity of oncofetal antigen-immature laminin receptor in human renal cell carcinoma

PURPOSE: The 32 to 44 kDa. oncofetal antigen-immature laminin receptor (OFA-iLR) is a multifunctional protein expressed by various tumors, including breast, lung, ovary and prostate carcinoma as well as lymphoma. OFA-iLR has been implicated in tumor invasiveness, metastasis and growth. Interferon-gamma producing effector T cells and interleukin (IL)-10 producing suppressor T cells specific for OFA-iLR have been described. MATERIALS AND METHODS: The 43515 IgG2a anti-OFA-iLR monoclonal antibody was used to detect OFA-iLR expression in human renal cell carcinoma tissue by flow cytometry and immunoblotting. Spontaneous or therapy induced immune responses against OFA-iLR were determined in patients with metastatic renal cell carcinoma. Proliferative and cytokine (interferon-gamma and IL-10) responses of peripheral blood mononuclear cells from patients with renal cell carcinoma against recombinant OFA-iLR were assessed. RESULTS: Using flow cytometry OFA-iLR was detected in all 13 tumors tested. Immunoblotting revealed differences in OFA-iLR expression in renal cell carcinoma and normal kidney tissue. OFA-iLR specific proliferative and cytokine responses of mononuclear cells were detected in all 6 patients tested. Importantly evidence was also obtained that treating metastatic renal cell carcinoma with tumor lysate pulsed dendritic cells would enhance OFA-iLR specific immunity. CONCLUSIONS: This study demonstrates that OFA-iLR is an immunogenic tumor associated antigen in human renal cell carcinoma. OFA-iLR specific effector T cells producing interferon-gamma may have a role in the control of tumor growth, whereas suppressor T cells producing IL-10 may promote tumor tolerance and, thus, tumor progression.
