Abstract Osteoarthritis (OA) is the most common form of arthritis, causing pain and progressive disability in millions of people worldwide. The commonly prescribed medications for OA, including non-steroidal anti-inflammatory drugs, have many side effects which has led the scientists to consider safer drugs as an alternative. Therapeutic effects of Curcumin on OA are increasingly declared, and its various aspects in suppressing inflammation and reducing the disease progression are examined more thoroughly. This study aims to discuss curcumin and OA to help scientists working in these fields. In this brief review, we took a look at OA pathogenesis, the role of the immune system, and the biomarkers involved in the onset and progression of the disease. We focused on available data on the anti-inflammatory effect and mechanism of treatment by curcumin on OA.

Abstract Background: Among suggested medications for the treatment of COVID-19, chloroquine derivates and angiotensin-converting–enzyme inhibitors (ACEIs)/angiotensin II type 1 receptor blockers (ARBs) are the two medications with conflicting effects on the development of the disease.
Objectives: The present study aimed to evaluate COVID-19 in patients with rheumatic diseases receiving chloroquine derivate.
Methods: Every patient with proven rheumatologic diseases registered in two referral centers in Tehran and Alborz, Iran was enrolled in the present descriptive cross-sectional study between May and June 2020. At first, the symptoms of COVID-19 were assessed, and if a case had suspicious symptoms, reverse transcription-polymerase chain reaction (RT-PCR) COVID-19 tests were done. Demographic and clinical data are documented for every patient. Then, the patients were grouped once according to their COVID-19 infection status and another time according to their hydroxychloroquine use.
Results: 1159 patients enrolled in the study with a mean age of 49.39 years. Frequency of hypertension was 22.17 %, diabetics (9.49%) and 20 (1.7%) patients were positive for COVID-19 testing. The most common symptoms of the COVID-19 positive cases were cough (5.2%) and fever (4%). There was no significant difference in receiving ACEIs/ARBs or other medications between COVID-19 positive or negative patients. Among the patients receiving hydroxychloroquine, 15 patients (1.7%) had proved COVID-19 versus 5 patients (1.7%) who were not receiving these medications (P>0.999).
Conclusion: The present study demonstrated that receiving ARBs or ACEIs was not different among patients with or without COVID-19. Moreover, receiving chloroquine derivate was not related to the development of COVID-19 in patients with rheumatologic disorders.

Abstract Introduction: Misdiagnosis and the resulting mismanagement are challenging issues in complicated cases which present with obscure complaints. Interpreting radiologic studies, especially conventional plain radiologic images, remains the most frequently prescribed and useful modality for the first step of assessment.
Case Presentation: In this report, we present a case of mismanagement of a strange foreign body in the maxillary sinus of a child not found in a facial x-ray.
Conclusion: Inexperienced non-radiologist physicians may make misdiagnoses when reading conventional x-rays.
