Background: Even though anti-neutrophil cytoplasmic antibodies (ANCA) are frequently linked to ANCA associated vasculitis (AAV), it's important to understand that other illnesses, including lung diseases, can also manifest as ANCA positivity. Finding the incriminated pathology might be difficult.
Aim: To report four ANCA-associated cases with a diagnosis problem.

Background: Searching for Rheumatoid Factors (RF) in patients with coronavirus disease (COVID-19) has rarely been described.
Objectives: To investigate the association between RF isotypes (IgM, IgA, and IgG) and different clinical presentations of COVID-19 in a series of Tunisian patients.
Study Design: Eighty-two COVID-19 patients were enrolled in this study.
Introduction: Denture swallowing is an uncommon incident. However, it should be suspected in edentulous elderly patients who wear removable dentures which are poorly cared for and maintain. The existence of neuro-psychiatric disorders may contribute to the occurrence of this adverse event.

One focal point of this debate is the largest negative inorganic C-isotope excursion recognized in the geologic record, the Shuram excursion, and whether this relic tracks the global-scale oxygenation of Earth's deep oceans. To help inform this debate, we conducted a detailed geochemical investigation of two siliciclastic-dominated successions from Oman deposited through the Shuram Formation.
