RESUMO
Cytogenetic analysis was performed in five cases of intestinal type gastric carcinoma. Three cases were near-diploid and two others were near-triploid. The chromosomes involved were: #9 (four cases), #8 (three cases), #1, and #7 (two cases each). The nonrandom chromosomal abnormalities included aberrations of chromosome #9 as trisomy or i(9q) or 9p+ marker chromosome and excess of 8q material (i.e., trisomy or i(8q) chromosome). Our results indicate that abnormalities of chromosome #9 are a common feature in a subgroup of intestinal type gastric cancers and that there are common cytogenetic abnormalities in gastric and large bowel cancer.

The present investigation shows that the capacity of thyrolymphography for demonstrating the morphologic features of various thyroid lesions is not inferior to that of isotope scanning. On the contrary, lymphography is an effective procedure for detecting small nodules that remain undetected by other methods. Contrast medium is more rapidly distributed to lymph nodes in patients with diffuse goiter and also in patients pretreated with Lugol's solution. Finally, it is shown that the contrast medium employed (Lipiodol Ultra Fluid) remains in the lymph nodes for a period of several months.

In this paper we present some elements of the history of 'scientific' psychiatric hydrotherapy and, moreover, of a particular form of the water-purifying ritual--that is, foot washing--among the populations living in Greece and in Orthodox communities in the Balkans. We speculate on the reasons that caused the virtual disappearance of the former, while the latter still flourishes.

Lymphoproliferative syndrome with well differentiated lymphocytes and moderate lymphocytosis in the peripheral blood includes a heterogeneous group of disorders, that present often difficulties in classification. We have studied the lymphocyte markers (ER, EMR, sIg and T3, T4, T8 antigens) in 36 cases who had lymphocytic infiltration in the bone marrow and peripheral lymphocyte counts less than 15 X 10(9) l-1. Four cases (11.1%) had the characteristics of T8 lymphocytosis and 31 had a B cell monoclonal proliferation in the peripheral blood. Of these, four were sIg-, EMR+, 19 were sIg+, EMR+ and 8 were sIg+, EMR-. Most patients (17/32) had the clinical picture of stage 0 and I B-CLL. Six cases presented as pure splenomegalic form of CLL, three had the features of immunocytic lymphoma and five had the features of lymphocytic lymphoma. It is concluded that the majority of lymphoproliferative disorders presenting with moderate lymphocytosis represent early forms of B-CLL. Occasionally cases of lymphocytic or immunocytic lymphoma may present problems of differential diagnosis since there may be a dissociation of phenotypic characteristics of lymphocytes between tissues and peripheral blood.
