Janeway

Janeway is a term that can refer to several different entities, most notably a character from the television series Star Trek: Voyager and a medical textbook. This article will focus on the latter, specifically the Janeway Lesion, a symptom of Infective endocarditis.

Janeway Lesion

A Janeway Lesion is a symptom of Infective endocarditis, a serious infection of the inner layer of the heart. These lesions are non-tender, small, erythematous or haemorrhagic macular or nodular lesions on the palms or soles. They are caused by septic emboli which have lodged in the dermal capillaries causing microabscesses.

Clinical Presentation

Janeway lesions are often associated with other symptoms of infective endocarditis, such as Osler's nodes, Roth's spots, and splinter hemorrhages. They are typically painless, in contrast to Osler's nodes, which are painful.

Diagnosis

Diagnosis of Janeway lesions, and by extension infective endocarditis, is typically made through a combination of clinical presentation, blood cultures, and echocardiography. The presence of Janeway lesions can help to confirm a suspected diagnosis of infective endocarditis.

Treatment

Treatment for Janeway lesions involves addressing the underlying infective endocarditis. This typically involves long-term antibiotic therapy, and in some cases, surgery may be required to repair or replace damaged heart valves.
