Kaposi sarcoma (KS) is an angioproliferative neoplasm that affects the skin and lymph nodes. Human herpesvirus-8 (HHV-8) triggers KS by infecting the endothelium and inducing angiogenesis through the production of vascular endothelial growth factors and cytokines. KS is characterized by purplish or hyperpigmented plaques involving the skin and mucous membranes, and visceral involvement is very rare.

Article Synopsis
- Immunoglobulin G4-related disease (IgG4-RD) is a condition affecting multiple organs, characterized by painless swelling and inflammation, with common sites being the pancreas and salivary glands.
- Diagnosis involves various tests (serological, imaging, histopathological) and primary treatment is with glucocorticoids, which often yields good results.
- A case study highlights a geriatric male incorrectly suspected of pancreatic cancer, who was found to have autoimmune pancreatitis, a type of IgG4-RD, and responded well to steroid treatment.
Use of high-stakes exams in a course has been associated with gender, racial, and socioeconomic inequities. We investigated whether offering students the opportunity to retake an exam makes high-stakes exams more equitable.

- * A study at Fundación Cardiovascular de Colombia from 2014 to 2019 analyzed 378 neonates, finding that 30.7% had ECM, with gastrointestinal issues being the most common type.
- * Neonates with ECM faced lower birth weights, longer hospital stays, and more postsurgical complications, though survival rates were similar between those with and without ECM; these insights emphasize the need for ECM screening to aid in clinical decision-making, particularly in resource-limited settings.
