Background: This study was designed to evaluate and compare the diagnostic value of magnetic resonance imaging (MRI) and indirect magnetic resonance arthrography (I-MRA) imaging with those of arthroscopy and each other. Methods: This descriptive-analytical study was conducted in 2020. All patients who tested positive for labrum lesions during that year were included in the study. The patients underwent conservative treatment for 6 weeks. In the event of no response to conservative treatment, MRI and I-MRA imaging were conducted, and the patients underwent arthroscopy to determine their ultimate diagnosis and treatment plan. Imaging results were assessed at a 1-week interval by an experienced musculoskeletal radiologist. Image interpretation results and arthroscopy were recorded in the data collection form. Results: Overall, 35 patients comprised the study. Based on the kappa coefficient, the results indicate that the results of both imaging methods are in agreement with the arthroscopic findings, but the I-MRA consensus rate is higher than that of MRI (0.612±0.157 and 0.749±0.101 vs. 0.449±0.160 and 0.603±0.113). The sensitivity, specificity, negative predictive value, positive predictive value, and accuracy of MRI in detecting labrum tears were 77.77%, 75.00%, 91.30%, 50.00%, and 77.14%, respectively, and those of I-MRA were 88.88%, 75.00%, 92.30%, 66.66%, and 85.71%. Conclusions Here, I-MRA showed higher diagnostic value than MRI for labral tears. Therefore, it is recommended that I-MRA be used instead of MRI if there is an indication for potential labrum lesions.

Brucellosis is an old, infectious and common zoonosis whose causative agents are Gramnegative bacteria from the Brucella genus. Brucellosis is transmitted through direct contact with infected animals or using unpasteurized dairy products of goats, pigs, camels, sheep, buffalo and cows. Brucellosis is still the most common zoonosis in the world, with most of cases occurring in developing countries. Today, an approach to traditional medicine and medicinal plants, especially with regards to the repeated recommendations of the World Health Organization, is a necessity. One-third of chemical drugs are produced by using plants and there is a high potential to produce more drugs from plants. Medicinal plants are helpful in the management of various conditions, especially bacterial diseases. Although there is not enough scientific evidence regarding the clinical effectiveness of herbal drugs for the treatment of brucellosis, there is strong evidence on the antimicrobial effects of herbal drugs to prevent infection. Therefore, this article seeks to describe the antibacterial effects of some plant-derived essential oils or extracts, so that they can serve as promising choices to develop new anti-Brucella medications, as suitable alternatives to conventional antibiotics for brucellosis, as much as possible, taking into account the benefits of these herbal drugs.
