Case report: Emergence of autochthonous cutaneous leishmaniasis in northeastern Texas and southeastern Oklahoma.

Autochthonous human cases of leishmaniasis in the United States are uncommon. We report three new cases of cutaneous leishmaniasis and details of a previously reported case, all outside the known endemic range in Texas. Surveys for enzootic rodent reservoirs and sand fly vectors were conducted around the residences of three of the case-patients during the summer of 2006; female Lutzomyia anthophora sand flies were collected at a north Texas and southeast Oklahoma residence of a case-patient, indicating proximity of a suitable vector.

A national outbreak of Salmonella serotype Tennessee infections from contaminated peanut butter: a new food vehicle for salmonellosis in the United States.

Background: Salmonella serotype Tennessee is a rare cause of the estimated 1 million cases of salmonellosis occurring annually in the United States. In January 2007, we began investigating a nationwide increase in Salmonella Tennessee infections.

Methods: We defined a case as Salmonella Tennessee infection in a patient whose isolate demonstrated 1 of 3 closely related pulsed-field gel electrophoresis patterns and whose illness began during the period 1 August 2006 through 31 July 2007.

State-based surveillance to determine trends in meningococcal disease.

Objectives: Meningococcal disease (MD), is a leading cause of meningitis in the U.S. The purpose of this study was to determine the epidemiology of MD in Oklahoma, including trends, high-risk populations, and outcomes.

Multistate outbreak of Burkholderia cenocepacia colonization and infection associated with the use of intrinsically contaminated alcohol-free mouthwash.

Background: No guidelines exist for the type of mouthwash that should be used in patients at increased risk for pneumonia. In 2005, we investigated a multistate outbreak of Burkholderia cenocepacia associated with an intrinsically contaminated alcohol-free mouthwash (AFM).

Methods: We conducted a case-series investigation.

Objective: To describe current cannulation of the internal jugular vein (CIJV) practice in a university anesthesia department.

Design: Prospective, observational, and not randomized.

Setting: Operating rooms of the Hospital of the University of Pennsylvania.
