Implantable Cardiac Defibrillator Lead Infective Endocarditis Due to Specie: A Rare Case in An Immunocompetent Man.

Background: species are known to cause dental caries and periodontal disease, and infrequently cause native or prosthetic valve endocarditis mostly in immunocompromised persons. With an increasing use of implantable cardiac devices, early clinical suspicion and a rapid diagnosis of endocarditis is essential for optimal treatment to reduce complications and mortality. Bacteremic infection with in immunocompetent persons is uncommon.

ATTR Epidemiology, Genetics, and Prognostic Factors.

Transthyretin amyloid cardiomyopathy (ATTR-CM) is an underdiagnosed disease and an underestimated cause of both heart failure and conduction abnormalities. It is characterized by pathologic accumulation of extracellular protein arising from unstable transthyretin (TTR) tetramers, which dissociate into monomers that misfold, aggregate, and form insoluble fibrils that are resistant to proteolysis. Cardiac amyloidosis appears in two distinct forms: hereditary and wild-type.

Anti--methyl-d-aspartate receptor encephalitis triggered by emotional stress.

A 22-year-old woman presented with disorganized behaviors, restlessness, and subacute decline in mental status in the setting of stress. Extensive workup for autoimmune diseases disclosed positive anti--methyl-d-aspartate (NMDA) receptor antibodies. We recommend that fertility preservation should be discussed and stress management should be considered in patients with a history of anti-NMDA autoimmune encephalitis because this can help in preventing relapse.
