Diffuse Cutaneous Systemic Sclerosis With Normotensive Scleroderma Renal Crisis and Myopericarditis: A Case Report.

Systemic sclerosis (SSc) is a rare autoimmune disease characterized by fibrosis and multi-organ dysfunction, primarily affecting the heart, lungs, and kidneys. Scleroderma renal crisis (SRC) can present as hypertensive or normotensive, with the latter being more challenging to diagnose due to the absence of hypertension at onset. Normotensive SRC carries a worse prognosis, with an increased risk of renal failure and a poor response to treatment.

Bradycardia, Renal Dysfunction, Atrioventricular Nodal Blockade, Shock, and Hyperkalemia (BRASH) Syndrome: A Case Report Highlighting the Importance of Early Recognition and Management.

BRASH syndrome, characterized by bradycardia, renal dysfunction, atrioventricular nodal blockade, shock, and hyperkalemia, is a newly defined condition that can lead to significant morbidity and mortality if not promptly recognized and treated. The triggers for this syndrome often include medication interactions, dehydration, and nephrotoxic insults, particularly in older patients with limited renal reserve and cardiovascular disease. In this report, we present the case of an 88-year-old female with multiple comorbidities who exhibited symptoms of prostration, bradycardia, hypotension, and altered mental status, along with laboratory findings (hyperkalemia and renal dysfunction) consistent with BRASH syndrome, triggered by hypovolemia associated with a urinary tract infection.

Giant Right Atrium: An Extreme Structural Damage Case Due to Rheumatic Heart Disease.

Giant right atrium (RA) is a rare finding in adults. We report a case of a 53-year-old female with rheumatic heart disease (RHD) previously submitted to two mitral valve replacements. She presented at the emergency room with signs of heart failure.

COVID-19-Induced Myocarditis and mRNA Vaccine-Related Pericarditis: A Case Report.

Acute inflammatory cardiac disease is an increasing cause of COVID-19 vaccine-induced complications. We report a case of acute pericarditis following the second dose of the COVID-19 vaccine (BNT162b2) in a 49-year-old woman with previous COVID-19-induced myocarditis and heart failure. A clinical presentation compatible with acute decompensated heart failure elevated troponin levels and a cardiac-MRI showing myocardial fibrosis and inflammatory pericardial effusion led to the diagnosis of perimyocarditis.

Could Fahr's Syndrome Have More Than One Simultaneous Etiology?

Fahr's syndrome is a rare, genetically dominant, inherited, neurological disorder characterized by abnormal deposits of calcium in the basal ganglia and the cerebral cortex. Symptoms include motor dysfunction, dementia, headache, spastic paralysis, abnormal ocular findings and seizures. Hypoparathyroidism is the most common endocrine disorder related to this syndrome, however, there are other metabolic, infectious and genetic causes.
