    Association Between the Elasticity of Hip Muscles and the Hip Migration Index in Cerebral Palsy
    (2019) Analan, Pinar Doruk; Aslan, Hulya; https://orcid.org/0000-0002-3528-3712; https://orcid.org/0000-0002-7138-246X; 30779197; AAA-8043-2021; AAK-9104-2021
    Objectives-Cerebral palsy (CP) increases the risk of hip displacement during childhood. Abnormal hip muscle forces have been proposed as the predisposing factors. In CP, the amount of hip displacement is commonly evaluated by the Reimers hip migration index (MI) on an anteroposterior pelvic radiograph. To the best of our knowledge, the association between the elasticity of hip muscles measured by shear wave elastography and the MI has not been studied yet. Herein, we aimed to analyze the correlation between the elasticity of hip muscles and the MI. Methods-Bilateral hips of 25 children with spastic CP were included prospectively in this study. Anteroposterior pelvic radiographs were used to measure the MI. Shear wave elastography was performed to evaluate the elasticity of muscles. The correlation between the MI and the elasticity of hip flexor and adductor muscle groups was assessed. Also, the association between the elasticity of agonist/antagonist muscles was analyzed. Results-The MI showed fair to good correlations with hip flexors and adductors for both readers (0.71 >= r >= 0.52). The mean MIs of the patients +/- SDs were 22.64% +/- 7.79% for reader 1 and 21.55% +/- 8.83% for reader 2. The elasticity of agonist/antagonist muscle groups showed little/no to a weak correlation for both readers (0.32 >= r >= -0.07). Conclusions-Although, hip flexor and adductor muscle elasticity showed a correlation with MI, it seems very hard to say that increased elasticity of hip flexor and adductor muscles causes hip dislocation.

    Role of acoustic radiation force-based elasticity imaging in endometrium pathologies
    (2020) Cenkeri, H. C.; Bidaci, T. B.; Yilmaz, B.; Desteli, G.; 33047689
    Backround: Ultrasonography is difficult to distinguish between endometrial pathologies and often requires curettage. ARFI (Acoustic Radiation Force-Based Elasticity Imaging) is a new ultrasonography elastography method. Using ARFI, it is possible to obtain information about the likelihood of the tissue benign or malignant. Aim: The aim of this study is to evaluate the contribution of ARFI to differentiate endometrial pathologies in hysterectomy specimens. Subjects and Methods: Our study was prospectively, January-May 2017, performed in randomly 45 cases of 41-91 years of age (mean 58.3 years) who have decided to have hysterectomy. Hysterectomy was performed for uterine prolapse and endometrial hyperplasia in elderly patients and menorrhagia in young patients. Pathology results were compared with ARFI values and endometrial thickness. ANNOVA test was used for the comparison of ARFI values. Results: Pathology revealed 14 cases of endometrial atrophy, 11 cases of proliferative phase, 10 cases of polyp, 6 cases of endometrial hyperplasia, and 4 cases of endometrium cancer. There is a statistically significant difference between mean ARFI values of endometrium, subendometrium, and myometrium of the groups (P < 0.05). There was a statistically significant difference between the mean endometrial thickness of the groups (P < 0.05). Conclusion: Endometrium ARFI contributes to the differential diagnosis of endometrial pathologies. Subendometrial and myometrial ARFI values decrease in polyps and increase in hyperplasia. Our study shows that the addition of subendometrium ARFI to gray-scale sonography before deciding on invasive procedures in endometrial pathologies may improve diagnostic accuracy. We concluded that further in vivo studies will establish the usefulness of this technique for preoperative diagnostic measures.
