Discrete-event simulation modeling for housing of homeless populations.

The San Francisco Bay Area has experienced a rapid rise in homelessness over the past decade. There is a critical need for quantitative analysis to help determine how to increase the amount of housing to meet the needs of people experiencing homelessness. Noting that the shortage of housing available through the homelessness response system can be modeled as a queue, we propose a discrete-event simulation to model the long-term flow of people through the homelessness response system.

Schönlein-Henoch purpura associated with gastric Helicobacter pylori infection.

Schönlein-Henoch purpura is characterized by palpable purpura, colicky abdominal pain, gastrointestinal hemorrhage, arthralgias, and renal involvement. Bacterial and viral infections, as well as drugs and diseases associated with immune complexes, are thought to be responsible. We describe the case of a 21-year-old woman with Schönlein-Henoch purpura and chronic active gastritis with erosions.

[Abdominal variant of benign symmetrical Launois-Bensaude lipomatosis].

We report on a patient with an abdominal type of benign symmetrical Launois-Bensaude lipomatosis. New aspects of the pathogenesis of abnormal distribution of the fatty tissue are also discussed.
