Pictures of polar bears: Using visitor employed photography to identify experience indicators in the Arctic National Wildlife Refuge.

The purpose of this research is to apply visitor employed photography (VEP) to recreation management to develop indicators of the wildlife viewing experience. VEP and semi-structured interviews were used at a popular polar bear viewing destination in the Arctic National Wildlife Refuge (Arctic Refuge). Visitors to the Arctic Refuge who participated in an on-site semi-structured interview were asked to participate in a VEP procedure after their visit.

Tricuspid Valve Replacement in an HIV-Infected Patient with Severe Tricuspid Regurgitation Secondary to Remote Endocarditis.

Surgical intervention for severe tricuspid regurgitation secondary to remote infective endocarditis has been infrequent, especially in patients also infected with the human immunodeficiency virus (HIV). We describe the case of a 62-year-old HIV-positive man, with a 24-year history of endocarditis caused by intravenous heroin use, who presented with severe tricuspid regurgitation. The patient was initially asymptomatic, was taking antiretroviral medications, and had a satisfactory CD4 count and an undetectable viral load, so we decided to manage the regurgitation conservatively.

Risk stratification and prognosis of human immunodeficiency virus-infected patients with known or suspected coronary artery disease referred for stress echocardiography.

Background: Patients with human immunodeficiency virus (HIV) infection are at increased risk of accelerated coronary artery disease (CAD) and cardiovascular events. Stress echocardiography (SE) is routinely used for risk stratification and prognosis of patients with known or suspected CAD. The prognostic value of SE in this high-risk group is unknown.

Lactococcus garvieae endocarditis: report of a case and review of the literature.

Bacterial endocarditis due to Lactococcus garvieae is extremely unusual, and may actually be underreported due to its morphologic and biochemical similarities with enterococci. Only three cases have been reported in the medical literature, and all involved prosthetic valves. We report a case of native valve bacterial endocarditis caused by L.

[Topographic selectivity of Kaposi's sarcoma. General considerations and review of the literature].

Visceral involvement, particularly of the gastrointestinal tract is common in patients with AIDS-related Kaposi's Sarcoma. A patient with AIDS and digestive Kaposi's Sarcoma who had lesions located in the mouth, pharynx and esophagus with a well-defined delimination to the esophago-gastric junction was studied A discussion and a review of the medical literature was made in order to find a physiopathological mechanism to explain this topographical selectivity.
