[Multivariate statistical analysis in predicting bronchopulmonary complications after surgical interventions in cancer of the lung]. / L'analisi statistica multivariata nella previsione delle complicanze broncopolmonari dopo intervento chirurgico per cancro del polmone.

A multivaried statistic process, the linear discriminant analysis, applied to VEMS, CV, I.T., FEF 25-75, pH, PaO2, PaCO2, was used by the authors to foresee, in 42 patients suffering from bronchogenous carcinoma, the arising or absence of respiratory complications after operation. With such method, the falsely positive or negative previsions, resulted to be 13 with a total percentage of error as high as 30%. These results suggest that, even when elaborated through the multivaried analysis, the parameters studied do not allow to adequately discriminate the patients who would develop, after operation, bronchopulmonary complications from those who would be exent from them.

[Delayed recognition of traumatic rupture of the diaphragm. Diagnostic and therapeutic problems]. / Rotture traumatiche del diaframma a riconoscimento tardivo. Problemi diagnostici e terapeutici.

The Authors face the diagnostic and therapeutical problems involved in the tardy recognition of diaphragmatic breakages. On the basis of two clinical cases observed, they emphasize the relative frequency of this lesion, the variability of the clinical pictures, the limits of the clinical and radiological diagnostics, the utmost seriousness of the complications. They face the problem of the choice of the surgical way of approach and the techniques for repairing the diaphragmatic lacerations.

[Familial polyposis of the colon]. / La poliposi familiare del colon.

The Authors face the problems involved in the colonic familial polyposis, with particular attention to the surgical treatment of subjects bearing neoplastic degeneration. They, moreover, report their clinical experience, and compare it with the experience of other centres.

[Carcinoid tumor of the rectum]. / Il carcinoide del retto.

The Authors show a case of rectal ampulla carcinoid, and review the literature thereabout. They suggest the removal through sphincter according to Mason, which technique, in their opinion, can ensure a satisfying radicalness when the diameter of carcinoid is shorter than 2 cm.

[Traumatic rupture of the diaphragm. Diagnostic problems and surgical therapy]. / La rottura traumatica del diaframma. Problemi diagnostici e di terapia chirurgica.

The Authors show 10 cases of traumatic disruption of diaphragm, subsequent to close or open trauma, all subjected to urgency operation. They discuss the problems concerning diagnosis and surgical tactics, and point out the frequency of visceral and osseous associated lesions and their importance in conditioning prognosis.

[Perforations in neoplasms of the colon]. / La perforazione in corso di malattia neoplastica del colon.

The authors show their experience about the surgical treatment of colonic perforations in course of neoplastic disease. Their casuistry is compared with those of other centres.

[Surgical treatment of cancer of the splenic flexure]. / Il trattamento chirurgico del cancro della flessura splenica.

The authors report their experience in the surgical treatment of the cancer of splenic flexure. The neoplasiae arising in such place are usually diagnosed in a more advanced phase than in the other colon segments. This results in a survival at a shorter interval.
