Cardiac Metastasis Presenting As Right Ventricular Outflow Obstruction.

Right ventricular outflow tract obstruction (RVOTO) is characterized by an increased systolic pressure gradient between the right ventricle (RV) and the pulmonary artery. This rare condition can be diagnosed via echocardiography and may arise from various causes, including cardiac masses, pulmonary atresia with a ventricular septal defect, tricuspid valve thrombus, graft or wire calcification, or a cardiac tumor. We present the case of a 73-year-old male who was hospitalized after a syncope episode.

Prevalence of Symptomatic Gallbladder Disease After Bariatric Surgery: A Literature Review.

Introduction Gallbladder disease (GBD) encompasses several medical conditions, including gallbladder stone formation, biliary colic, and cholecystitis. These conditions may arise following bariatric surgery, including bypass or laparoscopic sleeve gastrectomy (LSG). The development of GBD after surgery may be attributed to various factors, including the formation of stones shortly after the procedure, the exacerbation of existing stones due to the surgery, or inflammation of the gallbladder.

The Effect of COVID-19 on QTc Prolongation.

Background The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses angiotensin-converting enzyme-2 receptors on host cells to enter the cells. These receptors are expressed on heart muscle tissue and the tissues of other major organs, which supports the primary accepted theory for the direct cardiac cell injury of coronavirus disease 2019 (COVID-19) and the associated cardiorespiratory manifestations. The SARS-CoV-2 infection leads to unstable myocardial cell membranes due to hypoxia, myocarditis, myocardial ischemia, and abnormal host immune response.

A Puzzling Diagnosis of Cerebral Vein Thrombosis in a COVID-19-Vaccinated Patient.

Cerebral vein thrombosis (CVT) is a rare condition equivalent to deep vein thrombosis of the intracranial veins. Delayed diagnosis will result in severe and disabling complications. We report a case of a 59-year-old man with CVT with no significant past medical or surgical history.

An Unusual Presentation of Spontaneous Rupture of Dermoid Cyst.

Intracranial dermoid cysts are exceptionally rare tumors. Interestingly, this condition has a low mortality rate but a high morbidity rate due to its numerous complications. We report a case of a 62-year-old man who presented with a headache and was found to have a ruptured dermoid cyst, complicated with the dissemination of lipid droplets within the subarachnoid space.

A Case of Neurosyphilis With Penicillin Failure.

Neurosyphilis is any involvement of the central nervous system (CNS) by . The CNS may be involved at any stage of infection. A 54-year-old previously healthy African American male was hospitalized due to a two-year history of progressive cognitive decline.
