ABSTRACT
A case report of a benign pancreatic tumor and its differential diagnosis is presented. The patient was a 31-year-old woman with a benign solid and papillary epithelial pancreatic tumor. Differentiation from a malignant tumor and from a hormonal active tumor was possible by the smooth boundaries and absence of contrast medium enhancement on CT. Exact diagnosis was found by laparatomy and histology.

Intracranial pressure and cerebral blood flow velocity were recorded in term healthy neonates during the first 3 days of life using non-invasive methods (LADD-fontanometry and cw-Doppler sonography). Intracranial pressure increased from 4.0 +/- 2.7 cm H2O to 5.8 +/- 2.7 cm H2O and maximal cerebral blood flow velocity in the anterior cerebral artery (ACA) increased from 33 cm/s to 58 cm/s as calculated from a Doppler shift of 0.63 to 1.10 kHz and vascular resistance decreased between the 1st and 3rd day of life. These alterations could not be demonstrated in the femoral artery. This is in accordance with other registrations obtained by different methods and under various conditions. They allow an explanation of some well known physiological phenomena like alterations of cranial volume and the structure of the bony skull in the first days of life. Furthermore, these physiological variations may have implications for the origin of cerebral damage during the perinatal period, especially of hypoxic-ischaemic encephalopathies.

The serum iron and serum copper level was determined in fifteen patients with lymphogranulomatosis before and during the course of the therapy. While the serum copper was increased in all stages, for the serum iron only in the stages III and IV a tendency to diminution was found. With obtaining the remission a significant increase of the serum iron and a significant decrease of the serum copper developed. The normalization of serum iron and serum copper suggests a remission, the dissociation of the two parameters an activity of the lymphogranulomatosis.
