Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. Racial disparities in CRC incidence and mortality have been well documented. In addition, lower rates of CRC screening among ethnic minorities have been reported. Therefore, we tested the effectiveness of a patient navigator (PN) in increasing compliance with(More)
Skin biopsies from 221 parasitologically confirmed cases of tegumentary leishmaniasis caused by Leishmania braziliensis spp. were evaluated with respect to histopathology, the qualitative and quantitative nature of the cellular infiltrate, and the presence of Leishmania amastigotes. These variables were cross correlated with the Leishmania-specific immune(More)
P64k is a meningococcal protein from Neisseria meningitidis that has been obtained by recombinant DNA technology. Recombinant P64k has been extensively characterized by physicochemical and immunological methods. Lately this protein has been found to act as a versatile immunological carrier for weak antigens in mice. In the present work, a Phase I clinical(More)
Six patients suffering from an unusual form of colitis produced by Strongyloides stercoralis hyperinfection are described. In contrast to the usual Strongyloides hyperinfection syndrome, in which small intestinal and pulmonary manifestations are seen in patients with some forms of immunodeficiency, the patients described here presented with only a(More)
Vitamin A deficiency in its subclinical form is a world health problem in young children. The problem is probably under recognized in the United States and other developed countries who do not normally consider their citizens to be malnourished. Lack of a simple screening test to measure subclinical deficiency adds to this problem. Consequently, focused(More)
A case of ectopic human Fasciola spp. infection in the cecal wall is reported. The patient, a 27-year-old Korean woman, resident in Seoul, Korea, presented with nausea, vomiting, and epigastric tenderness. One week later a palpable mass was discovered in the right iliac fossa. A clinical diagnosis of a carcinoma of the colon was made and the patient(More)
A nematode larva undistinguishable from Dioctophyme renale was found in the subcutaneous tissues of the abdomen of a 23-year-old woman from Ohio. This is the third case of Dioctophyme larva reported in humans. Although it is not known how the infection was acquired, we suggest that ingestion of raw fish was the probable source. We further hypothesize that(More)
An immunocompetent man developed malaise, fever, progressive weight loss, eosinophilia, and transient pulmonary infiltrates that responded to steroid treatment but recurred after its discontinuation. Examinations of feces, bronchoalveolar lavage fluid, and pulmonary tissue obtained during a 50-day period of hospitalization yielded negative results. When a(More)
