Neurinosarcoma of Vater's ampulla is rarely observed. A case is presented in which the tumour did not occlude the ampulla and was thus detected intraoperatively. The head of the duodenum and the pancreas were ablated. Histological examination showed a fasciculated neoformation, in which the individual fasciculi ran parallel to or crossed each other. The nuclei displayed distinct atypical pictures. The little cytoplasm there was could only be clearly made out in areas involved in oedematous dissociation.

Neurophysiological examination of end-plate function in patients with lung cancer.

Twenty-eight patients affected by lung cancer were studied with neurophysiological and clinical examinations to show the prevalence of alteration of neuromuscular transmission. During repetitive stimulation at 20 Hz we found in 6 cases (22%) an increment (> 20%) and in 4 cases a decrement ( > 10%) of the size of muscle action potentials. In 15 patients (57%) we found low sensory action potential amplitude (< 11 uv). In 3 (11%) of the 6 cases with incremental response the overall examination suggested a disorder of neuromuscular junction such as Eaton-Lambert syndrome. Our results suggest that the peripheral nervous system involvement in patients affected by lung cancer is higher than usually estimated.

[Suppurative complications in acute pancreatitis].

The authors examining suppurative complications caused by acute necrotizing pancreatitis point out how such complications can arise early at the same time of acute pancreatitis with large spread in peripancreatic tissues and spaces and with worse prognosis or have a late appearance with a trend to localize and circumscribe. Four cases of pancreatic abscess, three of which largely diffused brought to death in spite of surgery, are reported.

[Totally implantable central venous systems in neoplastic patients].

Long-term chemotherapeutic drugs administration in cancer patients requires the use of special devices such as TIS (Totally Implantable Systems) for central venous access without complications such as thrombosis and sepsis. From January 91 to January 95, 42 TIS were implanted in the same number of oncology patients at the Institute of Surgical Pathology of the University of Chieti. The catheters were inserted by surgical incannulation of the cephalic vein in 36 cases, of the external jugular vein in 5 cases and of the internal jugular vein in 1 case. Four complications occurred consisting of 3 cases of haematoma, which were resolved by wound revision and 1 case of port dislocation treated by repositioning without removing the system. It is concluded that TIS are currently the best technological solution in long-term central venous catheterization because of the very low rate of complications and the easier nursing management and significant improvement in the quality of life for these patients.
