[Interprovincial migration and regional imbalance. The Argentine case (1960-1991)]. / Las migraciones interprovinciales y el proceso de diferenciacion regional. El caso argentino (1960-1991).

PIP: "This article focuses on the role of geographic mobility in the process of uneven regional development in Argentina. From the analysis of gross geographic product and provincial migratory growth rate between censuses for 1960-70, 1970-80 and 1980-91, the authors conclude that provinces of destination tend to improve their position relative to the rest, while there is no general pattern for provinces [of origin].... There is a circular relation between migration patterns and the relative position of provinces, and emigration does not seem to help reduce the imbalance." (EXCERPT)^ieng

Clinical and histological kidney involvement in human kala-azar.

A 19-year-old women developed prolonged fever, weight loss, hepatosplenomegaly, anemia, leukopenia, and hyperglobulinemia. Appropriate tests indicated that she had visceral leishmaniasis (kala-azar). Urinalysis demonstrated significant proteinuria and microhematuria with the presence of red cell casts. A kidney biopsy was performed. Light microscopy showed a slight mesangial thickening and segmental mesangial proliferation. Immunofluorescence demonstrated deposits of immunoglobulins A and M, complement, and fibrinogen. Electron microscopy showed subendothelial and intramembranous deposits. After treatment with N-methylglucamine antimonate the proteinuria and microhematuria disappeared and the patient recovered uneventfully.
