This case report examines an unusual presentation of a non-typhoidal Salmonella serovar with limited prevalence in the literature. This is the first case report to associate specifically the Salmonella muenchen serovar with rhabdomyolysis and myocarditis. This case report reviews the diagnostic criteria for myocarditis and explores the diagnostic dilemma of troponin elevation in the setting of rhabdomyolysis. It demonstrates that Salmonella muenchen has the ability to present in a broad range of individuals with complications extending beyond classical gastrointestinal symptoms...

BACKGROUND: Endomyocardial biopsies (EMB) are an important diagnostic tool for myocarditis and other infiltrative cardiac diseases. Routinely, biopsies are obtained under fluoroscopic guidance with a substantial radiation burden. Despite procedural success, there is a large sampling error caused by missing the affected myocardium. Therefore, multiple (>6) biopsies are taken in the clinical setting. In cardiovascular magnetic resonance (CMR), late gadolinium enhancement (LGE) depicts areas of affected myocardium in myocarditis or in other infiltrative cardiomyopathies...

Metformin is a widely used anti-diabetic drug and increasing evidence suggests that metformin have profound cardioprotective effects under both diabetic and non-diabetic situations. The protective benefits of metformin have been proved in diabetic patients with cardiovascular complications and in experimental animals with myocardial infarction and cardiac hypertrophy. In the present study, we found that treatment with metformin inhibited the cardiac expression of pro-inflammatory cytokines including tumor necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1β) and interleukin 6 (IL-6) in endotoxin-challenged mice...

BACKGROUND: Approximately 1.5 million adults in Germany suffer from an inflammatory rheumatological condition. The most common among these are rheumatoid arthritis and spondyloarthritis-above all axial spondyloarthritis, including ankylosing spondylitis (Bekhterev's disease) and psoriatic arthritis. These systemic inflammatory diseases often affect the heart as well. METHODS: This review is based on pertinent articles retrieved by a selective literature search, on current European guidelines, and on the authors' clinical experience...

Viper envenomation is common in North Africa. Cardiac complications are not common features of snakebites, the clinical picture of which is usually dominated by toxin-associated neurological, hematological, and vascular damage. There are rare reports of acute myocardial infarction and/or ischemia caused by snakebites, while myocarditis after envenomation has not yet been reported, to our knowledge. We report the case of a 43-year-old woman admitted to our intensive care unit after viper envenomation complicated by acute heart failure with acute pulmonary edema, in a state of cardiogenic shock, accompanied by multi-organ failure, intravascular disseminated coagulation, and neurological damage...

Although survival of patients with different types of cancer has improved, cardiotoxicity induced by anti-neoplastic drugs remains a critical issue. Cardiac dysfunction after treatment with anthracyclines has historically been a major problem. However, also targeted therapies and biological molecules can induce reversible and irreversible cardiac dysfunction. Cancer immunotherapies over the last years have revolutionized the clinical management of a wide spectrum of solid and hematopoietic malignancies previously endowed with poor prognosis...

Herein we describe the case of a 1-month-old boy with acute viral myocarditis, who presented with two kinds of paroxysmal supraventricular tachycardia, and who was cured after medical treatment. He was brought to the emergency room with poor feeding due to fever. On the third day of hospitalization, a narrow QRS tachycardia (180-200 beats/min) was detected. Echocardiography showed a high echoic area at the atrial septum around the atrioventricular node. The patient was clinically diagnosed with acute myocarditis...

Immune therapies represent a quantum leap in the fight against cancer. Recently approved immune checkpoint inhibitors that target receptors involved in immune escape of cancer cells (including cytotoxic T lymphocyte-associated antigen-4 (CTLA-4), programmed cell death protein-1 (PD-1), and programmed cell death protein ligand-1 (PD-L1) are increasingly being used for therapeutic benefit in a number of cancers. The robust anti-cancer activity of these agents has been accompanied by the recognition of new adverse effects, often due to the over activation of immune system, that may limit their therapeutic benefit and adversely impact outcomes...

Kawasaki disease (KD) is an acute inflammatory vasculitis occurring in young children before 5 years and representing at this age, the main cause of acquired heart disease. A single infusion of 2 g/kg of intravenous immunoglobulins along with aspirin has reduced the frequency of coronary artery aneurysms from 25 to 5%. However, 10-20% of patients do not respond to standard treatment and have an increased risk of cardiac complications and death. The development of more potent therapeutic approaches of KD is an urgent need...

REVIEW
Asher Ornoy, Zivanit Ergaz
Parvovirus B19 infects 1 to 5% of pregnant women, generally with normal pregnancy outcomes. During epidemics, the rate of infection is higher. Major congenital anomalies among offspring of infected mothers are rare, as the virus does not appear to be a significant teratogen. However, parvovirus B19 infection may cause significant fetal damage, and in rare cases, brain anomalies and neurodevelopmental insults, especially if infection occurs in the first 20 weeks of pregnancy. Parvovirus B19 is also an important cause of fetal loss, especially in the second half of pregnancy when spontaneous fetal loss from other causes is relatively rare...

Pheochromocytoma is a rare tumor, usually benign, potentially lethal in case of crisis with acute release of catecholamines. The heart is a target and the clinical presentation can mimic various cardiac conditions, thus rendering diagnosis elusive. Cardiac magnetic resonance is a valuable non-invasive diagnostic tool for the evaluation of cardiomyopathies; it allows the identification of catecholamine-induced myocarditis pattern and, in some cases, it can detect the primary tumor. The definitive treatment of pheochromocytoma is surgical, while the acute crisis may require mechanical support to circulation...

Clozapine is the most effective anti-psychotic medication for treatment refractory schizophrenia. A growing number of case reports have linked infection to high clozapine levels and associated adverse outcomes. We present a systematic review of published cases to clarify the relationship between infection and elevated clozapine levels. The case reports were located through PubMed and Embase. In addition, 8 new cases from two Australian states were included. Demographics, psychiatric diagnoses and medical morbidities, medications, clinical symptoms, clozapine levels, inflammatory markers and final clinical outcome were extracted...

Group B coxsackieviruses (CVBs) are a group of common human pathogens causing various clinical symptoms. Although the virology of CVB is well known, there is limited information on viral pathogenesis and the relationship between clinical symptoms and viral phenotype, particularly for CVB type 2 (CVB2). In this study, two CVB2 strains were isolated: CB2/04/279 from a stool of an acute myocarditis patient with heart failure; and CB2/04/243 from an aseptic meningitis patient in 2004 in Korea. A high degree of homology was observed between the CB2/04/279 and CB2/04/243 full genome sequences...
