The Role of Coronary Computed Tomography Angiography in Evaluation of High Troponin Patients with Narrow-Complex Supraventricular Tachycardia.

Aim: The aim of this study was to investigate the relation of high-sensitive cardiac troponin T (hs-cTnT) elevation with characteristics of supraventricular tachycardia (SVT) episode (duration and maximum heart rate) and coronary computed tomography angiography (CCTA) findings in patients with SVT who presented to the emergency room with palpitation.

Methods: This retrospective, single-center, noninvasive study included all patients aged between 18 years and 65 years who presented to the emergency department due to narrow-complex SVT and underwent CCTA to rule out coronary artery disease (CAD) due to elevation of hs-cTnT and reverted back to sinus rhythm after intravenous adenosine. The first, second, and the maximum hs-cTnT levels were obtained from the database.

Cryptococcal osteomyelitis of the skull in a patient with transient lymphopenia.

Cryptococcus neoformans is a rarely reported cause for osteomyelitis. We report an extremely unusual case of calvarial cryptococcal osteomyelitis in a 42-year-old sub-optimally immunocompetent male. This case discusses the atypical presentations of cryptococcosis in HIV-negative patients and its importance of early diagnosis.
