Radial endobronchial ultrasound for the diagnosis of peripheral pulmonary lesions: A systematic review and meta-analysis.

Tissue diagnosis of peripheral pulmonary lesions (PPLs) can be challenging. In the past, flexible bronchoscopy was commonly performed for this purpose but its diagnostic yield is suboptimal. This has led to the development of new bronchoscopic modalities such as radial endobronchial ultrasound (R-EBUS), electromagnetic navigation bronchoscopy (ENB) and virtual bronchoscopy (VB).

Bleeding heart: a case of spontaneous hemopericardium and tamponade in a hyperthyroid patient on warfarin.

We describe the case of an 81-year-old female, diagnosed with hyperthyroidism-related atrial fibrillation. Given her CHA2DS2VASc score of 3, she was started on warfarin for stroke prevention. One month later, she was admitted with cardiac tamponade.

Giant cell myocarditis: a life-threatening disorder heralded by orbital myositis.

A 40-year-old man with a history of orbital myositis (OM) presented to the emergency department with ventricular tachycardia requiring electrical cardioversion. Postcardioversion ECG showed right bundle branch block, while an echocardiogram revealed an ejection fraction of 20% and a dilated right ventricle. Cardiac MRI produced suboptimal images because the patient was having frequent arrhythmias.
