    Notes: Abstract An unusual case of hepatic hydatidosis complicated by transphrenic migration of the hydatid cyst passing through the right hemidiaphragm, and penetrating the inferior pulmonary lobe causing a bronchial fistula, is presented. The computed tomographic (CT) study permitted the correct preoperative diagnosis.

    Notes: Abstract Fractal trees as a model for drainage systems are described in its generalized non-homogeneous form from the viewpoint of fractal geometry. Box covering techniques are used to show the numerical equivalence between the Hausdorff-Besicovitch dimension and the similarity dimension of the fractally-dominant dust formed by the sources. In this way, the similarity relationD=log (N)/log (1/r) is reinterpreted in terms of bifurcation and length ratio (r B andr L ) asD=log (r B )/log (r L ). We test this relation for non-homogeneous exact fractal trees and two natural drainage systems. The fact thatr B andr L are common parameters in quantitative geomorphology allows a trivial stimation of the fractal dimension of well-known drainage basins.

    Notes: Abstract Our objective was to investigate sexualcommunication and risk-taking behaviors among young menwho have sex with men (MSM). MSM aged 17 to 25 yearswere recruited from four areas throughout California. The construct Safer Sex Communication, assessedthrough principal-components analysis, was defined asperceived efficacy or experience in minimizing the riskof sexual HIV infection through communication with partners. In the 6 months prior to thesurvey, 35.6% of the MSM had participated in unprotectedanal intercourse (UAI). Adjusted logistic regressionanalyses found low Safer Sex Communication to be predictive of UAI. In addition, negativeattitudes toward safe sex, high perceived risk of HIVinfection, 10 or more male sex partners during theprevious 6 months, and use of cocaine in the past 6months were also independently related to UAI. SaferSex Communication skills should be an outcome ofinterventions designed to prevent HIV transmission amongyoung MSM.
