OBJECTIVES Upon onset of acute type A aortic dissection, the aortic true lumen generally becomes fixed around the supra-aortic branches in the greater curvature and Botallo's ligament in the lesser curvature of the aortic arch. Therefore, the pathways of the false lumen through the arch can be categorized as anterior, bilateral and posterior. We investigated the relationship between a false lum...

Background: Scoliosis is a health problem that causes a side-to-side curvature in the spine. The curvature may have an “S” or “C” shape. To evaluate scoliosis, the Cobb angle has been commonly used. However, digital image processing allows the Cobb angle to be obtained easily and quickly, several researchers have determined that Cobb angle contains high variations (errors) in the measurements. ...

background & objectives: tumor diathesis (td) is defined as granular proteinaceous precipitates on slide surface of cytologic smears. it is found in the background of smears of invasive carcinoma but not in all cases. the aim of present study was to determine the prevalence of td in cervicovaginal smears from patients with uterine cervix carcinoma. methods: cytological smears and histologi...

STUDY DESIGN  Retrospective cohortObjective: To determine if there are differences in important clinical outcomes between patients treated with a "preservation of the unilateral posterior muscular-ligament complex (PMLC) procedure" and a "hinge side anchoring procedure (HSAP)" for the treatment of cervical spondylotic myelopathy (CSM). METHODS  Nine hundred and forty-six patients underwent th...

BACKGROUND To explore the related influencing factors of adjacent segment degeneration (ASD) after cervical discectomy and fusion (ACDF). MATERIAL AND METHODS A retrospective analysis of 263 patients who underwent ACDF was carried out. Cervical x-ray and magnetic resonance imaging (MRI) were required before operation, after operation, and at the last follow-up. General information and some radi...

BACKGROUND Patients with severe cervical multilevel stenosis and an adequate lordotic curvature often undergo multilevel laminectomies with posterior instrumented fusions. Although the "gold standard" for the fusion mass remains iliac crest autograft, many require additional volume provided by bone graft expanders. Here, we studied the fusion rates for 32 patients undergoing multilevel cervical...

Background: Cervical spondylotic myelopathy (CSM) is a clinical disease which characterized by degeneration of the intervertebral discs and nearby spinal structures. The goal this study to compare laminoplasty (LP) versus laminectomy fusion (LF) for multilevel cervical in terms safety effectiveness. Methods: This meta-analysis from randomized non-randomized control study. database being used we...

Abstract Study design This is a prospective case-controlled study. Background To analyze the postoperative axial pain and cage subsidence of patients presenting with cervical spondylotic myelopathy (CSM) after modified procedure ACDF (mACDF). Methods Ninety CSM were prospectively collected from 2014 to 2018. The divided into spread group non-spread (48:42 ratio) according placement or without r...

we establish some relative volume comparison theorems for extremal volume forms of‎ ‎finsler manifolds under suitable curvature bounds‎. ‎as their applications‎, ‎we obtain some results on curvature and topology of finsler manifolds‎. ‎our results remove the usual assumption on s-curvature that is needed in the literature‎.

BACKGROUND Malignant growth and invasiveness of cancers is a function of both intratumoral and stromal factors. The accessibility to nutrients, oxygen and growth factors, the stromal composition, and the interference with the immune system all shape the tumor invasion front. A recent study has shown a prognostic difference with respect to different invasion patterns analyzed on histological spe...
