The dramatic increase of diagnostic imaging capabilities over the past decade has contributed to increased radiation exposure to patient populations. Several factors have contributed to the increase in imaging procedures: wider availability of imaging modalities, increase in technical capabilities, rise in demand by patients and clinicians, favorable reimbursement, and lack of ...

Adhesions occur with a high incidence after intra-abdominal surgery but can also develop due to infections, radiation or for idiopathic reasons. The formation of adhesions is initiated by tissue damage and is the result of peritoneal tissue repair involving the activation of the inflammatory system and the coagulation cascade. Acute ...

Paratesticular rhabdomyosarcoma is a rare but aggressive malignancy in children and adolescents. Prognosis is related to initial tumor resectability as well as staging of the disease based on tumor invasiveness, tumor bulk, nodal disease and metastases. We report the unusual presentation of paratesticular rhabdomyosarcoma with metastatic extension through the inguinal canal ...

The effects of irradiation on the intestinal tract of rats were studied. Enzyme studies with particular reference to esterase and alkaline phosphatase correlated with histologic studies of the injury process revealed a segmental radiosensitivity of the gut most marked in proximal segments and diminishing caudally. Variation in dose affects the rate of recovery rather than ...

Within the abdomen there are multiple organs that can cause acute pain. It is often difficult to determine the cause of acute abdomen clinically but it is usually the result of a non-traumatic pathology; in these instances plain film radiology is usually the initial investigation to determine serious pathology that may require surgical intervention. The second-line ...

Extra-abdominal desmoid tumours are slow-growing, histologically benign tumours of fibroblastic origin with variable biologic behaviour. They are locally aggressive and invasive to surrounding anatomic structures. Magnetic resonance imaging is the modality of choice for the diagnosis and the evaluation of the tumours. Current management of desmoids involves a multidisciplinary ...
