PURPOSE The aim of this study was to establish reference values for segmental myocardial strain measured by magnetic resonance (MR) cardiac tagging in order to characterize the regional function of the heart. MATERIAL AND METHODS We characterized the left ventricular (LV) systolic deformation in 39 subjects (26 women and 13 men, age 58.8 ± 11.6 years) whose cardiological study had not reveale...

BACKGROUND Fractured neck of femur generally requires operative fixation and is a common cause of admission to hospital. The combination of femoral nerve block and spinal anesthesia is a common anesthetic technique used to facilitate the surgical procedure. The optimal disposition of local anesthetic (LA) relative the femoral nerve (FN) has not been defined. Our hypothesis was: that the deposit...

abstract one of the most frequently encountered cases of rapid varied flow is the hydraulic jump. it occurs when a supercritical open channel flow changes into sub critical flow. in the present research, the experimental study of the hydraulic jump on seven sinusoidal corrugated beds with different wave steepness. the wave steepness of sinusoidal corrugated beds is in the range of 0.1667 to 0.7...

Two cases of recurrent perianal suppuration are described in which the underlying pathology is believed to be pilonidal sinus disease affecting the perianal skin directly. This has given rise to intersphincteric fibrosis and, in one case, a subcutaneous track almost completely encircling the anus. The pathogenesis of the condition and its possible relationship to previous surgery are discussed.

A 65-year-old man underwent computed tomography scan for surveillance of colon cancer and discovered an incidental 2 cm × 2.3 cm × 2.2 cm esophageal mass. The patient was completely asymptomatic, without dysphagia or weight loss. An upper gastrointestinal endoscopy was unremarkable while an endoscopic ultrasound (EUS) revealed an homogenous hypoechoic well-circumscribed subepithelial mass with ...

AIMS To investigate the right ventricular (RV) strain in pectus excavatum (PE) patients using cardiac magnetic resonance tissue tracking (CMR TT). MATERIALS AND METHODS Fifty consecutive pectus excavatum patients, 10 to 32 years of age (mean age 15 ± 4 years), underwent routine cardiac magnetic resonance imaging (CMR) including standard measures of chest geometry and cardiac size and function...

Based on the computation and analysis of three-dimensional unsteady flow induced by rotor/stator interactions, characteristics excitation towards bladed disks were studied, including frequency components circumferential wave components. By combining resonant condition disks, a design principle was derived for determining stator structural period from view averting resonance. The influences diff...

A 40-year-old Omani male, nonsmoker, presented with right-sided chest pain and weight loss of four months duration. He gave a history of pleural effusion five years ago, which was investigated thoroughly including Mantoux and multiple pleural biopsies. Though no definite diagnosis was made at that time, the effusion resolved spontaneously. His current chest radiograph (Figure 1) and a represent...
