Electrogastrography.

Electrogastrography (EGG) is the recording and the interpretation of gastric electrical activity. Recordings can be made from the gastrointestinal mucosa, serosa, or skin surface. Because of its ease of use, cutaneous EGG has gained wide acceptance.

Campylobacter jejuni enterocolitis presenting as inflammatory bowel disease.

We report a case of Campylobacter jejuni enterocolitis presenting as inflammatory bowel disease in a 19-year old woman. After a useless course of corticosteroids, ceftazidime and metronidazole, she was successfully treated with erythromicin. Campylobacter species represent an important cause of gastroenteritis in children and adults.

Evaluation of the vascular pattern of hepatocellular carcinoma with dynamic computed tomography and its use in identifying optimal temporal windows for helical computed tomography.

The aim of this work was to study the vascularization of hepatocellular carcinoma (HCC) by means of dynamic CT and to demonstrate the existence of optimal temporal windows for visualization of HCC in order to develop new protocols for helical CT of the liver. We studied, by means of dynamic CT, 42 histologically proved HCCs in 30 patients after injecting contrast medium (100 ml, 3 ml/s). We performed a time-density analysis of the aorta, liver, portal vein, spleen and lesion.
