Motion-sensitive phase contrast magnetic resonance imaging and magnetic resonance elastography are applied for the measurement of volumetric strain and tissue compressibility in human brain. Volumetric strain calculated by the divergence operator using a biphasic effective-medium model is related to dilatation and compression of fluid spaces during harmonic stimulation of the head or during int...

Congenital band compression syndrome should be considered in cases diagnosed prenatally or postnatally as intestinal obstruction. Presently described is a report of newborn admitted to hospital with abdominal distension and bilious vomiting. A suspected intestinal obstruction had been diagnosed in prenatal examination. Surgery revealed congenital band compressing ileal segments and preventing t...

Meralgia paresthetica is a mononeuropathy of the femoral cutaneous nerve with characteristic findings, usually secondary to injury or compression, being most common in the inguinal area. Exceptional cases associated with compressions caused by abdominal or pelvic tumors have been published, so it is always advisable to extend the study with imaging tests. We present a case associated with a ren...

BACKGROUND Many factors have been found to affect the difficulty of colonoscope insertion, such as age, gender, body mass index (BMI), history of abdominal surgery and operator etc. However, a scoring system may be more useful to predict the difficulty during colonoscopy. METHODS The individual and procedure-related data of 616 patients undergoing colonoscopy were prospectively collected from...

CONTEXT Superior mesenteric artery syndrome is a life- threatening upper gastrointestinal disorder due to compression of duodenum as it poses a difficult diagnostic dilemma. Third part of duodenum is in fixed compartment bounded anteriorly by the root of mesentery and superior mesentery artery and posteriorly by the aorta and lumbar spine. On barium contrast study and abdominal computerized tom...

A 71-year-old man presented with a history of progressive abdominal distention during the previous two years, accompanied by increasing difficulty in moving his lower extremities and a recurrent right scrotal mass on standing in the past two months. Physical examination revealed that the patient had prominent abdominal distention and a soft mass in the right scrotum (Figure 1). Computed tomogra...

Obstructive jaundice secondary to abdominal tuberculosis is extremely rare. We present a patient with jaundice secondary to compression of the common bile duct by TB lymphadenitis. A 49-year-old woman was admitted to our department for nausea,epigastric pain and jaundice. Abdominal ultrasonography and computer tomography scan were suggestive of stenosis of the distal common bile duct caused by ...

Recent studies have demonstrated that for the same chest compression force during mechanical cardiopulmonary resuscitation (CPR), the carotid artery-to-jugular vein pressure gradient and carotid blood flow are increased when the phasic rise of intrathoracic pressure is enhanced by abdominal binding and simultaneous ventilation at high airway pressure with each chest compression (SCV). The objec...

percutaneous vertebroplasty is a promising therapeutic technique for pain control in patients with pathologic fractures of vertebral bodies. percutaneous vertebroplasty is an appropriate treatment for vertebral pathologic fractures, which is resistant to other usual treatment. it is a useful and only choice in special cases, because of less tissue damage and there is no risk of open surgery and...

BACKGROUND The roles of antagonistic activation of abdominal muscles and of intra-abdominal pressurization remain enigmatic, but are thought to be associated with both spinal unloading and spinal stabilization in activities such as lifting. Biomechanical analyses are needed to understand the function of intra-abdominal pressurization because of the anatomical and physiological complexity, but p...
