background diffusion-weighted imaging (dwi) is a form of magnetic resonance imaging (mri) based on measuring the random brownian motion of water molecules within the biological tissues and is particularly useful in tumor characterization. objectives the purpose of this study was to evaluate the diagnostic value of dw mri and the apparent diffusion coefficient (adc) for preoperative grading of a...

Introduction: Radiation therapy is one of the main treatments for rectal cancer. In three-dimensional conformal radiotherapy, exposure of healthy tissue around the tumor is unavoidable. The small intestine is the most important organ at risk of rectal cancer radiotherapy. Intestinal complications are a major factor limiting the dose radiotherapy for rectal cancer. The most com...

The evidence of the literature indicates that the adrenal cortex produces a variety of hormones, some of which, like desoxycorticosterone, act predominantly to maintain a normal water and electrolyte balance (1), while others, like corticosterone, are effective chiefly through preventing hypoglycemia, either by facilitating the formation of sugar from protein (gluconeogenesis) (2) or by inhibit...

giant cell glioblastoma is an extremely rare variant of glioblastoma (who grade iv) which is characterized by a predominance of bizarre, multinucleated giant cells. these tumors comprise of 0.8% of brain tumors and up to 5% of glioblastomas. in pediatric age group, these tumors are still uncommon with only around 53 published cases since 1952. here, we report a case of a 12-year old female pati...

background multiple classifications can be used to define the magnitude of aortic injury. the vancouver classification (vc) is a new and simplified computed tomography-based blunt aortic injury (bai) grading system correlating with clinical outcomes. objectives the objectives of this study are: 1) to describe the severity of aortic injury in a center with a predominantly surgical approach to ba...

5. The patient may be killed by an excess of salt, fluid or DCA; the venous pressure does not give warning of this. Autopsy may reveal pleural and pericardial effusions when there was no rise of venous pressure in life. Chronic adrenal insufficiency is usually due to destruction or atrophy of the adrenal glands but it may complicate hypopituitarism and it may accompany adreno-genital virilism. ...
