with the introduction of the use of seatbelts in cars, mortality following motor vehicle crashes has decreased significantly. however, two patterns of injuries, the ‘seatbelt sign’ and ‘seatbelt syndrome’ have emerged. injuries may consist of traumatic abdominal wall disruption. we present two cases of severe abdominal wall disruption caused by a seatbelt injury and treated with primary repair....

background: the surgical management of cholesteatoma is a controversial issue, particularly regarding intact-canal-wall mastoidectomy (icwm) versus canal-wall-down mastoidectomy (cwdm). the current experiment compared the quality of  visualization in different middle ear structures using icwm with otoendoscopy with findings of cwdm by microscopy.materials and methods: the patients diagnosed wit...

background: more diagnostic techniques require a better understanding of the forces and stresses developed in the wall of the left ventricle. the aim of this study was to differentiate significant coronary artery disease (cad) patients using a non-invasive quantification of myocardial wall stress in the diastole phase. methods: sixty male subjects with sinus rhythm (30 patients with significant...

background hydatidosis is an infectious disease resulting from the development of the larval form of the parasite echinococcus granulosus in humans. the invasion of the chest wall by echinococcosis is rarely described. methods the current study reported all cases of chest wall hydatidosis treated in the department of cardiothoracic surgery from january 1990 to december 2011. results the mean ag...

In the modern electromagnetic environment, intra-pulse modulations of radar emitter signals have become more complex. Except for single-component signals, dual-component been widely used in current systems. order to make system ability classify and modulation at same period time accurately, this paper, we propose a multi-label learning method based on convolutional neural network transformer. F...

dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...

bronchiolo-alveolar carcinoma with subcutaneous chest wall metastasis is a very rare presentation. a case of 36- year-old male with metastatic subcutaneous chest nodule of bronchiolo-alveolar carcinoma, diagnosed by fine needle aspiration cytology, is reported here. cutaneous metastases are of diagnostic importance because they may be the first manifestation of an undiscovered internal malignan...

endometriosis is defined as the presence of functioning endometrial tissue outside the uterine cavity. endometriosis can sometimes occur in a previous surgical scar. scar endometriosis is rare and difficult to diagnose. it mostly follows obstetrical and gynecological surgeries. this condition is often confused with other surgical conditions. we are reporting one case of scar endometriosis invol...

introduction: based on the invasive studies it has been shown that factors such as age, the progress of eye disorders, lens fibers compression and the biochemical changes of ocular matrix alter the physical characteristics and elastic properties of eye. in this study, a noninvasive method of estimating human eye elasticityis proposed and its relation with age and gender is evaluated using ultra...
