Radiology of invasive amebiasis of the colon.

Entamoeba histolytica is a protozoan that is endemic in various parts of the world, including some areas of the United States. It may live in the large bowel in its cyst form without harming the host (commensalism) or, for as yet poorly understood reasons, invade the tissues as a trophozoite producing invasive amebiasis of the colon. In a review of over 3,000 cases of invasive amebiasis, the clinico-pathologic forms of the disease were: ulcerative rectocolitis (95%), typhloappendicitis (3%), ameboma (1.5%), and fulminating colitis and toxic megacolon (0.5%). Different radiographic patterns are seen in each clinical form with varying degrees of specificity. It is vitally important that this disease be included in the differential diagnosis of large bowel pathology even in nonendemic areas. Several referral patients who have received inappropriate therapy for inflammatory bowel disease with near disastrous results are seen at one of our institutions (Loyola) each year.

[Value of fetal hemoglobin in the diagnosis of neoplastic diseases].

In base of the actual interest on certain substances which measured in blood indicate the possible existence of neoplasic processes and because the elevation of fetal hemoglobin in patients with neoplasms or "pre-malignant" diseases, the authors of this paper decided investigate the levels of fetal hemoglobin in patients with neoplasic diseases, with and without treatment, comparing it with that obtained from a control group of healthy individuals or with infectious diseases, colagenopathies or bening tumours.

[Retrospective analysis of 44 cases of amyloidosis].

To know the natural history and the several clinical manifestations of amyloidosis, were reviewed retrospectively 44 cases at the Hospital General, Centro Médico Nacional, I.M.S.S. We found the secondary type in 79 per cent, primary shape in 9 per cent and 2 per cent associated with multiple myeloma. The frequency was similar in both sexes and was greater between the fifth and sixth decade of life; 34 per cent of the patients were diabetic; the symptomatology corresponded in 90 per cent of the cases to the main pathology, and only 9.9 per cent of the cases it was secondary to the amyloidosis itself; the alterations of laboratory test were not specific. The organs involved in the cases of primary amyloidosis were: spleen (100 per cent), kidney (80 per cent), heart (80 per cent), digestive tract (60 per cent), and lung (60 per cent). In the secondary shape: spleen (56 per cent), liver (41 per cent), adrenals (23 per cent) and kidney (11 per cent). Death could generally be adscribed to intercurrent pathology.

[Treatment of amebic hepatic abscess with tinidazole].

The patients reviewed in this study are thirty individuals with acute amoebic hepatic abscess. They were given tinidazol, two grams a day in one dose, for three days, with the object of ascertaining if this would be adequate treatment and without important side effects. The clinical diagnosis was confirmed by X-rays of the thoraz and abdomen, laboratory studies and liver scans. This latter as well as the laboratory tests were repeated at 10 and 20 days. Several of the patients were considered to be gravely ill. In 43% of the patients there was hepatomegaly grade II or II, in 30% there was jaundice, in 64% the abscess was very large and in 30% there were several abscesses. In keeping with the guide lines previously agreed on, 28 patients were cured, or that is 93%. There were no important side effects.
