abstract hydatid disease is caused by echinococcus spp. especially echinococcus granulosus that is the most common cause of hydatid disease in humans. this disease occurs either through direct contact with infected dogs or indirectly from the ingestion of contaminated water or food with eggs of worms. the most common site in human is the liver (59-75%), followed in frequency by lung (27%), kidn...

Background: Nowadays, advanced radiotherapy equipment includes algorithms to calculate dose. The verification of the calculated doses is important to achieve accurate results. Mostly homogeneous dosimetric phantoms are available commercially which do not mimic the actual patient anatomy; therefore, an indigenous heterogeneous pelvic phantom mimicking actual human pelvic region has been used to ...

This paper focuses on the analysis and control of some mathematical models representing the dynamics of a quadrotor. By using a normal form approach, the highly coupled parts in the quadrotor system are eliminated, while all possible properties of the original system are not changed. The bifurcations of the system are then analyzed. A two dimensional system is deduced at the origin which can de...

HYPOTHESIS Measurement of pelvic hemorrhage on computed tomographic (CT) scans can estimate the pelvic fracture component of total patient blood loss and predict the need for angiography. DESIGN Retrospective cohort study. SETTING Large level 1 trauma center. PATIENTS We examined data from 759 consecutive, nonreferral blunt trauma patients who sustained pelvic fracture. MAIN OUTCOME MEA...

OBJECTIVE To estimate whether botulinum toxin type A is more effective than placebo at reducing pain and pelvic floor pressure in women with chronic pelvic pain and pelvic floor muscle spasm. METHODS This study was a double-blinded, randomized, placebo-controlled trial. All participants presented with chronic pelvic pain of more than 2 years duration and evidence of pelvic floor muscle spasm....

background: gonad shielding has been recommended during pelvic x-rays since the 1950s. the popular method of gonad shielding is placement a lead shield in the midline of the pelvis. the aim of this study was to evaluate the prevalence and utility of gonad shielding in pediatrics undergoing pelvic x-rays.materials and methodsfollowing study approval, we retrospectively retrieved data from the di...

The goal of this study was to evaluate the role of portable primary trauma survey radiographs in the evaluation and management of anteroposterior (AP) compression pelvic injuries. A retrospective analysis was conducted at a level I academic trauma center. Twenty-seven adults with AP compressive class pelvic ring injuries who received both portable pelvic radiographs and pelvic computed tomograp...

The Shape Memory Alloy is a lightweight, compact and biocompatible actuation mechanism which is considered here to replace the current actuation technologies in assistive locomotion devices. This paper is aimed toward the development of an adaptive robust controller to deal with control problems in the actuation of shape memory alloys (SMA). In this research the ankle joint is considered to be ...

OBJECTIVE The purpose of this article is to review the relevant anatomy and sonographic, fluoroscopic, and MRI options for evaluating patients with pelvic floor disorders. CONCLUSION Disorders of the pelvic floor are a heterogeneous and complex group of problems. Imaging can help elucidate the presence and extent of pelvic floor abnormalities. MRI is particularly well suited for global pelvic...
