[Ocular toxoplasmosis in human immunodeficiency virus infected patients without concurrent central nervous system infection. Report of two cases].

Ocular toxoplasmosis is an uncommon complication of acquired immunodeficiency syndrome (AIDS), and it is generally described associated with central nervous system (CNS) lesions. We describe two cases of ocular toxoplasmosis in human immunodeficiency virus (HIV) infected patients, without concurrent CNS infection. Both developed bilateral or unilateral choriorretinitis with favorable response to antitoxoplasma therapy. None of them presented toxoplasmosis of the CNS coexisting with ocular lesions. Ocular toxoplasmosis should be considered in HIV infected patients although no involvement of the CNS is found.

Health indicators and the organization of health care systems in western Europe.

OBJECTIVES: This study investigated the association between health care systems and health indicators in developed countries. METHODS: Cross-national comparisons were conducted with regression analysis between 17 Western European countries with two types of health care systems: national health services and social security systems. RESULTS: Health care expenditures were inversely correlated to potential years of life lost to females and to infant mortality rates; they were positively correlated to life expectancy for females. Regression models predicted that countries with national health services systems would have lower infant mortality rates at similar levels of gross domestic product (GDP) and health care expenditures. Finally, increases in health care expenditures would decrease the ratio of observed to predicted infant mortality rates according to GDP; this decrease would be greater in countries with national health services than in those with social security systems. The model predicted this difference to be about 13% at average levels of health expenditures. CONCLUSIONS: National health services seem to be more efficient at producing lower infant mortality rates than social security systems in Western European countries.

The politics of health care reform in the United States, 1992-1994: a historical review.

In an analysis of the sociopolitical context of the debate on health care reform in the United States, the author focuses on the political events that led to the election of a Democratic administration in 1992; the evolution of the White House task force on health care reform and the interests and positions it represented; the connection between economic and political power in the United States; and the reasons for the defeat of the health care reform proposal. This historical analysis questions some of the dominant interpretations of the failure to reform health care, which assume that the U.S. population was not yet ready for these reforms.

[Syndrome of allopurinol hypersensitivity. Report of a new case and review of the Spanish literature].

Allopurinol is a drug of wide clinical use and good tolerance. Some patients develop severe hypersensitivity due to immunologic reaction to the drug. A new case which fulfills all the diagnostic criteria of the syndrome of allopurinol hypersensitivity with associated clinical manifestations of multiple mononeuritis and evidence of granulomas and vasculitis in liver biopsy as the most significant data is reported. The syndrome was favorably resolved following withdrawal of the drug without need for corticoid therapy. The characteristics of the cases described in the Spanish literature over the last few years are globally reviewed. The absence of mortality is of note. The inconvenience of prescribing allopurinol to patients with asymptomatic hyperuricemia is emphasized.

Cytotoxic and antimicrobial screening of selected terpenoids from Asteraceae species.

Twelve pure compounds originally obtained through a systematic chemotaxonomical study with Mexican plants of the Asteraceae, were subjected to a cytotoxic and in vitro antimicrobial screening. Three different cell lines in culture (KB, KB-VI and P388) were used in the cytotoxicity assay, while antimicrobial activity was tested against Gram-positive and Gram-negative bacteria, as well as Candida albicans. Of the twelve terpenoids tested, only taraxasterol showed antimicrobial activity against Staphylococcus aureus. The significant cytotoxic activity exhibited by five sesquiterpene lactones, and the moderate cytotoxicity of an eudesmane, is discussed.
