Objective: Endometriosis is a common gynecological disease among reproductive-age women. Numerous hypotheses exist regarding the pathogenesis of endometriosis. In Turkey, the consumption of Allium cepa (commonly known as the “onion cure”) is a popular treatment employed to alleviate a variety of gynecological disorders. Methods: In this study, our objective was to assess the therapeutic mechanisms of the onion bulb A. cepa using an autologous endometriosis model in Sprague-Dawley rats. Previous research has shown that A. cepa possesses anti-inflammatory, antioxidant, and antiapoptotic properties. We evaluated the pathological condition of endometriotic implants by employing hematoxylin-eosin staining and Ki67 immunohistochemistry analysis. Transforming growth factor-beta 1 (TGF-β1) and alpha-smooth muscle actin (α-SMA) have been identified as profibrotic markers that are highly overexpressed in endometriotic tissues relative to eutopic endometrial tissue. Furthermore, TGF-β1 influences the differentiation and progression of endometriosis. To quantify profibrotic activity, we measured TGF-β1 and α-SMA using the immunosorbent assay method.Results: Lower histologic evaluation scores for endometriotic implants were observed in the group receiving high-dose A. cepa relative to the other groups. Ki67 expression was reduced following the high-dose A. cepa regimen, which consisted of 30% A. cepa and 70% normal feed. However, no statistically significant differences in TGF-β1 or α-SMA levels were observed among the groups (<i>p</i>=0.7 and <i>p</i>=0.778, respectively). Conclusion: The findings suggest that A. cepa could serve as a therapeutic agent in endometriosis treatment, as evidenced by the reduction in proliferative potential. Nevertheless, A. cepa was not associated with significantly lower levels of endometriosis-associated TGF-β1 or α-SMA.

Study Design: Retrospective case control. Purpose: The authors of this study assessed whether the prevalence of paraspinal fatty degeneration correlates with the presence of Modic type I and I/II change in patients with low back pain (LBP). Overview of Literature: Modic changes are bone marrow and end plate changes visible on magnetic resonance imaging. Methods: A consecutive series of 141 patients who attended the neurosurgery outpatient clinic between April 2017 and September 2017 for nonspecific LBP were evaluated. Sixty-one patients with single-level Modic type I or I/II change constituted the patient group. Eighty age-, gender-, and body mass index (BMI)-matched patients without any Modic changes were recruited as the control group. A retrospective review was performed in 61 patients with Modic changes and 80 controls without Modic changes. The percentage of fatty muscle degeneration was graded by two reviewers using T2-weighted axial images at the L4–L5 level. The system was graded as follows: grade 0, normal; grade I, minimal focal or linear fat deposition; grade II, up to 25%; grade III, 25%–50%; and grade IV, more than 50%. Results: Sixty-one patients with nonspecific LBP and Modic type I or I/II change and 80 patients without Modic changes were evaluated. There was no difference between these groups in terms of age, gender, and BMI distribution. The mean muscle cross-sectional area in the patient and control groups were 1,507.37±410.63 and 1,681.64±379.69. Regarding fatty degeneration, a chi-square test of homogeneity was run, and the two multinomial probability distributions were not equal within the population analyzed. Conclusions: The novel finding of this investigation is that patients with Modic type I and I/II changes have greater amounts of fatty degeneration in their lumbar paraspinal musculature.
