Chest wall reconstruction becomes necessary when there are wall defects larger than 5 cm in diameter that compromise respiratory dynamics. Its purpose is to restore wall integrity, as well as to maintain waterproofing of the pleura, an aesthetic chest contour, and respiratory dynamics. In addition, the purpose is to protect vital intrathoracic organs, thus preventing lung herniation and paradox...

The normal posterior aortic wall echocardiogram shows anterior motion during left ventricular systole and predominantly posterior motion in three phases during left ventricular diastole. In six patients undergoing simultaneous left atrial angiograms and posterior aortic wall echocardiograms, there was excellent correlation between the posterior aortic wall motion and the change in the left atri...

hip dislocation occurs when the femur does not break and the force is transmitted towards the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. we present the case of a 26 year old patient involved in motor vehicle accident. clinical and imaging (radiography, ct) examination revealed an intertrochanteric fracture associated with ipsi...

frontal sinus fractures are of surgical importance because of the microbial flora covering the frontal air sinus and it's proximity with the duramater and brain. there is an increased risk of meningitis when fracture of the posterior wall of the frontal sinus is associated with a dural tear. in this condition, communication occurs between the contaminated space of the air sinus and the int...

The objective of this study was to evaluate and compare the effects Twin Block Forsus on Posterior Airway Passage (PAP) pharyngeal wall Thickness (PPWT) in treatment Class II division 1 malocclusion. This a 2-arm parallel, randomized controlled trial. A total 24 malocclusion patients indicated for with functional appliances were equally divided among (3M Unitek Corp, Monrovia, Calif) groups. Sk...

background: in intracavitary brachytherapy for gynecological cancers, various techniques are used to locate the anterior rectal wall nearest to the sources but there is no consensus on the best method to do so. this study aimed to compare a technique used routinely in some centers that employs a wire marker to locate the position of the maximum rectal dose point, versus the method recommended b...

The time-motion representation of the echogram was used to evaluate the left ventricular posterior wall motion in myocardial infarction. The left ventricular posterior wall echo was obtained in 10 normal subjects and 26 patients with chest pain admitted to a coronary care unit, including 11 with acute myocardial infarction (group 1), nine with old myocardial infarction (group 2), and six with c...
