Osteoarthritis (OA) is an age-related joint disease that characterized by degeneration of articular cartilage and chronic pain. Oxidative stress considered one the pathophysiological factors in progression OA. We investigated effects grape seed proanthocyanidin extract (GSPE), which antioxidant, on monosodium iodoacetate (MIA)-induced arthritis knee rat, animal model human GSPE (100 mg/kg or 300 mg/kg) saline was given orally three times per week for 4 weeks after MIA injection. Pain...
The purpose of this series was to describe the sonographic features dermatofibrosarcoma protuberans (DP) and correlate them with pathologic findings condition.The echogenicity marginal contour DP in 4 patients were observed on sonography, these then correlated cellular components histologic grading specimens. Additionally, color Doppler sonography conducted evaluate distribution blood flow signals tumors.All lesions located subcutaneous fat layer, abutted against skin, had a wide base. Two...
The aims of this study were to evaluate the associations between maximum standardized uptake value (SUVmax) and prognostic factors in invasive lobular carcinoma (ILC) compare these results with those ductal (IDC).The included pathologically confirmed ILCs (n = 32) IDCs 73). We retrospectively evaluated preoperative (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) measured SUVmax. pathologic reviewed regarding size, histological type, grade,...
Chondromyxoid fibroma is a rare benign primary bone tumor of cartilage. Despite characteristic radiographic appearance, chondromyxoid with atypical findings may mimic more common tumors.To describe the MR fibroma.MR images 19 histopathologically confirmed fibromas were retrospectively analyzed for signal intensity, periosteal reaction, adjacent abnormal marrow and soft tissue signal, patterns contrast enhancement.All cases showed hypointense to intermediate intensity internal hyperintense...
To assess the feasibility and safety of polyvinyl alcohol (PVA) embolization adjuvant to transarterial oily chemoembolization (P-TACE) in advanced hepatocellular carcinoma (HCC) with arterioportal shunts (APS).Nineteen patients who underwent PVA for APS before a routine (TACE) procedure were retrospectively reviewed. 10 these 19 follow-up TACE or P-TACE after (Group A), but nine only initial because progression HCC and/or underlying liver cirrhosis B). Hepatic function tests, grades, portal...
Eosinophic fasciitis (EF) is an uncommon connective tissue disease characterized by scleroderma-like cutaneous changes, peripheral eosinophilia, hypergammaglobulinemia, and elevated erythrocyte sedimentation rate (ESR).Typical histopathologic findings include chronic inflammatory infiltration affecting the deep fascia with lymphocytes, histiocytes, occasionally eosinophils.We report two cases of EF, first which a 36-year-old man tender brownish induration on both forearms, for 2...
There are very few reports assessing middle cerebral artery (MCA) stents using multidetector computed tomography (MDCT).To assess MCA CT angiography (CTA) in vivo evaluation: the differences CTA results according to three different kernels.We retrospectively evaluated 27 from 26 patients who underwent with 16- and 64-slice MDCT after percutaneous transluminal angioplasty stenting (PTAS). By CTA, medium-smooth kernel (B30), medium-sharp (B50), sharp (B60), lumen diameter, artificial luminal...
Autologous periosteal grafting is used as treatment for cartilage defects.To assess the role of MR imaging and ultrasonography in evaluation post-graft repair process with histologic correlation.Periosteal grafts obtained from tibia eight dogs were transplanted to experimental defects femoral condyles (15 knees). The control group was comprised three (five using 4.7T grafted specimens performed at one, two, four, eight, 16 weeks after transplantation. animals sacrificed time previously...
In the present study, signs of airflow obstruction on inspiratory and expiratory CT scans in 45 patients with rheumatoid arthritis were investigated. Radiologic findings evaluated correlated clinical data, which included factors pulmonary function tests results. A lung biopsy was performed five patients. The pattern as follows: infiltrative (n=15), obstructive (n=12), mixed (infiltrative obstructive; n=10), other complicating diseases (n=7), normal (n=1). rheumatologic factor between...
Purpose: The aim of this study is to evaluate the MR imaging features patients with external snapping hip syndrome. Materials and Methods: We retrospectively reviewed 63 images. images were analyzed according thickness contour iliotibial band gluteus maximus, presence bone marrow edema, bursitis, joint effusion other associated findings. Results: 22 hips syndrome depicted causes in twenty cases (90%). included thickening twelve (55%) and/or anterior maximus nineteen (86%), a wavy or ten...
The aim of this study was to analyze the imaging findings and clinical characteristics extratendinous migration calcific tendinitis shoulder with temporal changes.Seventy-six patients diagnosed by ultrasonography (US) or magnetic resonance (MRI) were enrolled in retrospective study. Clinical symptoms (on radiography, US, MRI) during an acute painful attack analyzed. Temporal changes analyzed 28 before 40 after attack. For comparison, 65 intratendinous included.Patients had a significantly...
Malignant mesenchymoma is an interesting but very rare tumor in which malignant differentiation has occurred twice or more. We report a case of retroperitoneal consisting osteosarcoma, leiomyosarcoma, liposarcoma and fibrosarcoma. Abdominal CT showed large mass with two separate distinct parts, namely area prominent calcification one clearly enhancing solid components. The contained histologically tumorous components no histologic admixure at the interfaces. densely calcified nodule...
Objective The objective of this study was to assess the lumen visibility carotid artery stents using multi–detector-row computed tomography (MDCT) angiography; compare medium-smooth, medium-sharp, and sharp kernels; correlate these results those digital subtraction angiography (DSA). Methods We retrospectively evaluated 52 from 51 patients who underwent 16- 64-slice MDCT angiography. Lumen diameters were measured 3 times by 2 neuroradiologists, artificial luminal narrowing calculated. To...
We report a case of insufficiency fracture the sternum in 70-year-old female patient with review literature. She complained sudden onset chest pain and aggravating dyspnea. has been managed corticosteroid due to chronic obstructive pulmonary disease for 15 years. Diagnosis sternal presented thoracic kyphosis was made on basis absence trauma history, radiologic findings lateral radiograph, bone scintigraphy computed tomography. Thoracic osteoporosis secondary menopause, therapy limited...
