Acute Epiploic Appendagitis in a COVID-19-Positive Patient With Antiphospholipid Syndrome.

As the coronavirus disease 2019 (COVID-19) pandemic is still underway, a range of clinical presentations and pathologies continue to present themselves in unexpected ways. One such pathology is that of epiploic appendagitis, an uncommon and underdiagnosed cause of acute abdominal pain. We present the case of a 50-something-year-old male who presented with left lower quadrant abdominal pain in the setting of acute COVID-19 infection, found to have acute epiploic appendagitis.

Congenital coronary artery-to-pulmonary fistula with giant aneurysmal dilatation and thrombus formation: a case report and review of literature.

Background: Coronary artery-to-pulmonary artery fistula is a rare disorder characterized by abnormal vascular communication between the coronary artery and pulmonary artery. While most patients remain asymptomatic, some might exhibit symptoms of myocardial ischemia, congestive heart failure, or even sudden cardiac death if coronary aneurysm, thrombosis, infective carditis, or other congenital cardiac defects coexist. Case presentation We present a 66-year-old male complaining of angina pectoris with a history of hypertension and active smoking.

Interstitial lung abnormalities in patients with early rheumatoid arthritis: A pilot study evaluating prevalence and progression.

Objective: Pulmonary disease is a leading cause of morbidity and mortality in rheumatoid arthritis (RA). In this study, we investigated the prevalence and progression of interstitial lung abnormalities (ILA) in a prospective cohort study of 18 subjects with early RA.

Methods: Eighteen adults diagnosed with anti-citrullinated protein-antibody-positive RA within the prior year underwent baseline high-resolution computed tomography (HRCT), symptom assessment, and pulmonary function and laboratory testing.

Retracted: Tetramethylpyrazine partially relieves hypoxia-caused damage of cardiomyocytes H9c2 by downregulation of miR-449a.

Inadequate oxygen supply is probably one of the most important pathophysiological mechanisms of cardiomyocyte damage in ischemic heart disease. Tetramethylpyrazine (TMP, also known as ligustrazine) is the main active ingredient isolated from the rhizome of Ligusticum chuanxiong Hort. A previous study reported that the TMP could exert cardioprotective activity.

Tracheal epithelial-myoepithelial carcinoma associated with sarcoid-like reaction: A case report.

Epithelial-myoepithelial carcinomas are rare tumors that primarily originate in the salivary glands but have also been found in the tracheobronchial tree. We report the first case of epithelial-myoepithelial carcinoma associated with sarcoidosis. A 61 year old Hispanic man presented with altered mental status and hypercalcemia.
