The Authors point out the doppler usefulness for the study of obstructive cerebrovascular pathology specially of the carotids with personal short casuistry.
The Authors describe two cases of "double pylorus" came to their observation. Such name mean the presence of a peri-pyloric gastro-duodenal fistula carrying out a second duct which lead in communication the gastric antrum with the upper part of duodenal bulb. Because of rarity of this pathology (58 cases are described in the literature) its frequency are usually undervalved, as well since the clinic no presents a special features in comparison with other diseases of the upper gastrointestinal tract.
The Authors present a case who occurred to their observation concerning a patient undergoing subtotal gastrectomy for cancer four years ago which have developed a phytobezoar in the gastric stump, treated with enzymatic dissolution with acetylcysteine associated with metoclopramide . According to the Literature, the Authors point out the etiology, pathogenesis and therapy of this non rate consequence of the gastric surgery.
After a short mention on the many last methods for venous pressure measurement, the Authors presents a relatively new method of this measurement with the Doppler ultrasonography. They point out its utility with regard to safenectomy by a study on 42 patients whose, at the present, only 10 preliminary results are available. This results allow to verify the opportunity of to value preoperatory and precisely the pressure drop obtainable with the safenectomy.
Difficulties still encountered in the coordinated interdisciplinary management of solid tumours in hospitals are discussed. Preliminary results obtained with a polychemical and immunostimulating protocol based on Corynebacterium parvum (introduced in 1973) in breast tumours immediately after surgery and in the advanced stage are presented. Two out of eight subjects with advanced forms died. Partial regression or a steady state were noted in the remainder. No locoregional recurrences or metastases were observed from 1 to 2 yr after the commencement of treatment in 22 patients treated in the immediate post-operative phase. These results are considered satisfactory, though a final evaluation would be premature. Stress is laid on the importance of immunostimulating management in the avoiding the immunodepression caused by the administration of drugs.

From January 1995 to December 1997, 170 patients with perforation of benign peptic ulcer (89 of them with perforation of iuxtapiloric ulcer, 54 duodenal and 27 gastric) were operated at A. Cardarelli's Emergence Department in Naples. Totally 153 repairs, 11 gastric or gastroduodenal resections, 4 ulcer excisions, 1 fundoplicatio and 1 transduodenal drainage were made. The last one was the only case of mortality. In 3 patients only dehiscence of the repair was registered (1.9% of complications). To reduce the risk of underevaluation of gastric neoplastic lesion or refractory ulcer to medical treatment, it's necessary to associate the repair with endoscopic follow-up and postoperative accurate medical therapy. So it's possible to obtain good results.
They have reported a case of multiple hepatic and cerebral metastasis of hypernephroma. The cerebral metastasis, probably after the hepatic one, are present respectively at a cerebellar and parietal-occipital level; the latter is the cause of a cerebral haemorrhage in a quite precocious phase of development.

Fifty-one migraine patients and 19 control subjects were examined by steady state visual evoked potentials (SSVEPs) procedure. The aim of this study was to develop a discriminant analysis and an artificial neural network (NN) classifier in order to discriminate between migraneurs during attack-free periods and normal subjects. Discriminant analysis correctly classified 72.5% of migraine patients with a false positive rate of 36.8%. The NN method had a sensitivity of 100% with a false positive rate of 15%. The results of this study confirm SSVEP pattern as a marker of migraine and demonstrate that NNs could be a useful method in the statistical analysis of topographic EEG data.
