ARFI imaging demonstrated a difference in muscle stiffness in the medial GCM between the CP and healthy groups. This method is a feasible imaging modality for the noninvasive assessment of contracting muscles in children with CP.
Objectives Platelet-to-lymphocyte ratio is a novel biomarker, recently shown to be correlated with atherosclerotic inflammation. This study investigated the role of platelet-to-lymphocyte ratio in patients with carotid artery stenosis and stroke. Methods Patients, who underwent carotid angiography with Multiple Detector Computed Tomography Angiography at our hospital, were retrospectively screened. Patients enrolled were divided into three groups based on the platelet-to-lymphocyte ratio. Patients with a platelet-to-lymphocyte ratio value between 55.0 and 106.71 were assigned to Group I, patients with a platelet-to-lymphocyte ratio value between 106.79 and 160.61 were assigned to Group II and patients with a platelet-to-lymphocyte ratio value between 162.96 and 619.61 were assigned to Group III. The carotid arterial stenosis calculated was classified as per the criteria of North American Symptomatic Carotid Endarterectomy Trial. Results One hundred fifty patients were included in our trial (mean age 61.9 ± 13.1 with 104 males). The rate of carotid arterial stenosis was detected to be higher in patients with a high platelet-to-lymphocyte ratio value (p = 0.010). Additionally, the platelet-to-lymphocyte ratio was positively correlated with the carotid arterial stenosis percentage (r = 0.250, p = 0.002). In the multi-variate regression analysis, platelet-to-lymphocyte ratio was detected to be an independent variable with respect to stroke (odd's ratio = 1.012, confidence interval = 1.001-1.024, p = 0.031). Conclusions Increased platelet-to-lymphocyte ratio could be a simple and practical marker of the clinical course in patients with carotid arterial stenosis.
Strain elastography is useful in differentiating between benign and malignant cervical LNs, thereby informing decisions to perform a biopsy and/or surgery, and facilitating follow-up.
Objectives
To assess the feasibility of ultrasound and shear wave elastography (SWE) in the diagnosis of breast cancer–related lymphedema.
Methods
Forty‐one patients with a history of unilateral breast surgery and axillary dissection or sentinel lymph node excision were included in this prospective study. The patients were classified as having normal findings, latent lymphedema, and clinical lymphedema on the basis of a physical examination, lymphedema index scores, and limb circumference measurements. The thickness and stiffness of the cutaneous and subcutaneous tissue of the forearm and arm were measured by ultrasound and SWE. The thickness and stiffness of the cutaneous and subcutaneous tissue of the affected limb and contralateral limbs of the normal, latent lymphedema, and clinical lymphedema groups were compared.
Results
The mean age ± SD of the 41 patients was 55.42 ± 10.12 years. There were 15 patients with normal findings, 10 with latent lymphedema, and 16 with clinical lymphedema. In the latent lymphedema group, the thickness measurements of the cutaneous tissue of the affected forearm and the cutaneous and subcutaneous tissue of the affected arm were significantly greater than those of the contralateral forearm and arm (P = .034; P = .022; and P = .002, respectively), and the stiffness measurements of the cutaneous and subcutaneous tissue of the affected forearm were significantly greater than those of the contralateral forearm (P = .011; and P = .002). In the clinical lymphedema group, the thickness and stiffness measurements of the cutaneous and subcutaneous tissue of the affected forearm and arm were significantly greater than those of the contralateral limb (P < .001–P = .032).
Conclusions
Ultrasound and SWE are effective for diagnosing breast cancer–related lymphedema even at a latent stage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
