The authors reviewed their experience in the emergency treatment of complications of esophageal cancer. They have treated 5 cases of acute obstruction, bleeding (4 cases), perforations or rupture (5 cases), feeding and neoplastic obstruction of esophageal endoprostheses (30 cases), dislocations and migrations of endoprostheses (15 cases), damage of endoprostheses (1 case) and, finally, acute complications after laser treatment.
The authors describe the clinical case of a patient undergoing a porto-caval shunt for portal hypertension, in which the patency of the anastomosis was checked by ultrasound examination.
The Denver valve peritoneo-jugular shunt has proved to be a valid therapeutic procedure in the treatment of refractory ascites. After briefly outlining the indications and advantages of the Denver valve and explaining how it is applied, the authors report the results obtained in their patient population.
The authors reported 6 cases of pyloric stenosis treated endoscopically by a new technic. Results have been good in all cases.
Caustic ingestions show, nevertheless medical progress, many clinical and therapeutical problems; particularly risk factors of stenotic and neoplastic evolutions as well as of functional outcome are little known. A case of Barrett's esophagus after acid sulphuric ingestion is the starting point of some personal considerations, after revision of literature.

The caustic burns of the oesophagus still play a significant role in the framework of oesophageal conditions, both in terms of therapeutic approach in the acute phase, when high morbidity and mortality rates are recorded, and of long-term consequences. These are as follows: stenoses of varying extent, carcinoma, wall deformation, oesophago-bronchial fistulae and motor disturbances. This paper is concerned with the clinical, diagnostic and therapeutic implications of these late consequences.
Twenty-six patients with stage III and IV esophageal cancer were randomly studied to evaluate the influence of fat emulsions (Intralipid) infusion on blood coagulation during total parenteral nutrition (TPN). The patients were divided into two groups: the first group (13 patients) received 24h. TPN; in the second group (13 patients) 1000 ml of 10% Intralipid were added to TPN via a peripheral vein over a period of 12 h. (1.8-2.1 g/kg/day). Primary hemostasis, platelet adhesiveness, alterations in fibrin formation and risk factors were evaluated before treatment (Time 0), after 7 days (Time 1) and after 14 days (Time 2). Statistical analysis of results was also carried out. On the basis of the obtained results it is observed that Intralipid at the administered doses, did not cause any alterations in blood coagulation and particularly in platelet adhesiveness.

NAG activity was measured in the serum of 40 diabetic subjects and 38 normal subjects. Diabetic subjects were divided into 8 groups on the ground of diabetic pattern, therapy and complications. Results showed significantly higher NAG activity in diabetics in comparison with normals. Inside the 8 groups of diabetic subjects, correlation between serum NAG activity and Hg A1 concentration appeared significant (P less than 0.001). Therefore NAG activity in diabetics appears rather related to the degree of glycometabolic control than to the presence of diabetes complications.

Porotic hyperostosis, characterized by small and localized perforations on the surface of cranial bones, is considered a good indicator for assessing the health and nutritional status of past human populations. The most widely accepted theory at present indicates that anemias, either acquired or of genetic origin, are responsible for the bony lesions described as porotic hyperostosis. In this paper, the prevalence of these lesions in two skeletal samples from Latium (central Italy) was used to evaluate health and life conditions in Italy after the collapse of the Roman Empire. One sample belongs to the Roman Imperial Age (1st-3rd centuries A.D.) rural town of Lucus Feroniae; the other comes from the 7th century A.D. Lombard necropolis of Selvicciola. The prevalence of cribra orbitalia and cribra cranii was quite similar in the two samples but slightly more frequent in the Medieval community. Differential diagnosis suggested iron deficiency anemia in early childhood as the causative agent of the hyperostotic lesions in both samples. These results may be interpreted in light of previous examinations of same samples and according to their respective historical and socio-economical characteristics.
