Troponin elevation to 1.00 ng/mL ( less then 0.01 ng/mL) warranted a cardiac angiography which revealed new-onset systolic heart failure with reduced ejection fraction with normal coronary vessels. A relatively rapid improvement in her clinical course suggested that a functioning tumor could be the underlying etiology. Diagnostic work-up for pheochromocytoma showed elevated metanephrine and normetanephrine. Subsequent surgical biopsy of the adrenal mass was consistent with pheochromocytoma. It was a rare case presentation of pheochromocytoma with catecholamine-induced cardiomyopathy and multiple organ failure.Infective endocarditis (IE) involving multiple cardiac valves is uncommon and has more risk of complications. We present an interesting case of infective endocarditis involving both aortic and tricuspid valves, suspected based on clinical presentation. He is a 54-year-old male with history of intravenous drug abuse (IVDA) who presented with exertional dyspnea, fevers/chills, fatigue, and temporarily vision loss. On exam, he had a low-grade fever, systolic murmur, bilateral crackles in lungs, and left hemineglect. He had leukocytosis and elevated BNP. First EKG showed first-degree AV block. CT head showed a subacute stroke in the right posterior cerebral artery (PCA) distribution. Transthoracic echocardiogram revealed a large tricuspid valve vegetation. He developed a second-degree heart block and a transcutaneous pacemaker was placed. Due to high concern for aortic valve involvement, a transesophageal echocardiogram was done revealing a large mobile tricuspid valve vegetation and an aortic valve ring abscess. He underwent abscess debridement and replacement of the aortic and tricuspid valve. He was found to have a ventricular septal defect which was also repaired. He recently had antibiotics for presumed pneumonia that is likely the reason for negative cultures. He received an 8-week course of Ceftriaxone for culture negative infective endocarditis and subsequently recovered well. This case report highlights that, although rare, the presence of right and left sided IE is possible and suspicion of aortic valve involvement is crucial in the setting of AV nodal blocks and peripheral embolic events. In patients with progressive heart blocks, transvenous pacemaker placement and valve replacement should be considered immediately to prevent further morbidity and mortality.Macrophage Activation Syndrome (MAS) is a potentially fatal inflammatory condition that can rapidly lead to multi-organ failure if inadequately treated. Also, known as secondary Hemophagocytic Lymphohistiocytosis (sHLH), MAS is commonly seen as a complication of systemic inflammatory disorders, like systemic juvenile idiopathic arthritis (sJIA) and systemic lupus erythematosus (SLE). However, MAS can also present as a complication of malignancies and infections, particularly viral infections like Epstein-Barr virus (EBV), cytomegalovirus (CMV) and HIV. Here we describe a patient with an underlying history of SLE and Sjogren's disease who was found have both EBV and CMV infections, presented to our facility with fever, lymphadenopathy, pneumonia and pancytopenia. Patient was treated in line with sepsis in the intensive care unit but rapidly developed multigrain failure despite early aggressive treatment. As will be discussed below, patient had characteristic signs and symptoms of MAS with biochemical parameters pointing towards the same.We present a rare case of recurrent nonbacterial thrombotic endocarditis (NBTE) and stroke despite anticoagulation. A 48-year-old man with history of antiphospholipid syndrome, prior nonbacterial aortic valve endocarditis status post valve replacement and prior stroke was found to have acute ischemic stroke while on apixaban and nonbacterial thrombotic endocarditis of mitral valve. This was initially managed conservatively with therapeutic dose of enoxaparin, but the patient later underwent mitral valve replacement. Unfortunately, the patient later passed away with hemorrhagic stroke while on enoxaparin.The idiopathic inflammatory myopathies (IIM) are rare sporadic disorders with an overall annual incidence of approximately 1 in 100,000 and with a higher incidence in women. IIM is an autoimmune process leading to muscle inflammation due to a 'dysfunctional adaptive immune response evidenced by cell-mediated myocytoxicity, a high prevalence of autoantibodies and overexpression of Major Histocompatibility (MHC) I and II molecules on the muscle sarcolemma'. These autoimmune processes can be appreciated as inflammatory infiltrates in muscle biopsies. Common clinical findings in patients diagnosed with IIM include proximal muscle weakness, elevated creatinine kinase levels, circulating autoantibodies, radiological findings of muscular inflammation, and sometimes edema; in some patients, systemic symptoms such as dysphagia can also be present. Currently, there is no specific IIM classification scheme that incorporates all IIM subtypes; however, the four major IIM subtypes include dermatomyositis, polymyositis, inclusion body myositis, and immune-mediated necrotizing myopathy (IMNM). learn more Two clinical cases are presented in this case report to illustrate a smoldering IIM, antisynthetase syndrome, and a more progressive IIM, anti-signal recognition particle IMNM; highlight the utility of the myositis-specific autoantibody panel for early diagnosis, targeted therapy, and prognosis; and offer primary care providers clues to IIM diagnosis.We present a case of severe symptomatic hyponatremia (94 mEq/L) in a male patient who presented with nausea, vomiting, and multiple falls. The patient was found with symptomatic hypo-osmolar hypovolemic hyponatremia secondary to volume loss from vomiting, diuretic use, and consumption of solute-free water. To manage such a severely hyponatremic patient, concomitant 3% hypertonic saline and DDAVP were initiated with successful slow and sustained correction of sodium without complications of osmotic demyelination syndrome.Sarcoidosis is a multisystem disease involving the lungs in up to 90% of cases; however, 30% of patients will have systemic sarcoidosis, including involvement of the heart. Cardiac sarcoidosis can affect any part of the heart and manifest in various ways, with the most common presentations being AV block, arrhythmias, heart failure and sudden cardiac death. Due to the overlap of symptoms and other cardiac diseases, including silent disease, cardiac sarcoidosis is difficult to diagnose. Many cases are underreported. However, due to the nature of the disease, cardiac sarcoidosis can have serious consequences that can be prevented with early intervention. This paper will focus on the challenges in diagnosing cardiac sarcoidosis, how to differentiate cardiac sarcoidosis from other common conditions by detecting subtle clinical differences, and how various investigations and imaging modalities should be used in aiding diagnosis and determining prognostic severity, such that early intervention can be initiated.
