Is It Antiphospholipid Syndrome?
The diagnosis of bacterial endocarditis remains a challenge, as nearly half of cases develop in the absence of preexistent heart disease and known risk factors. Not infrequently, a blunted clinical course at onset can lead to erroneous diagnoses. We present the case of a 47-year-old previously healthy man in which a presumptive diagnosis of antiphospholipid syndrome was made based on the absence of echocardiographically detected heart involvement, a negative blood culture, normal C-reactive protein (CRP) levels, a positive lupus anticoagulant (LAC) test, and evidence of splenic infarcts. The patient eventually developed massive aortic endocarditic involvement, with blood cultures positive for Streptococcus bovis, and was referred for valvular replacement. This case not only reminds us of the diagnostic challenges of bacterial endocarditis, but also underlines the need for a critical application of antiphospholipid syndrome diagnostic criteria
Hiccups and Inappropriate ADH Secretion Syndrome as Presentations of Tick-Borne Disease
Tick-borne diseases (Lyme disease and tick-borne encephalitis) are becoming a major public health concern. Rapid and correct diagnosis is crucial for complicated cases but is often delayed because of low suspicion or unusual clinical presentation. In this paper the authors describe two atypical presentations of Lyme disease and tick-borne encephalitis in order to help clinicians resolve diagnostic challenges
