[Colonic radiography by double-contrast enema in the elderly patient with the use of trimebutine maleate]. / Radiografia del colon per clisma a doppio contrasto nel paziente anziano con l'impiego del maleato di trimebutina.

About 15% of hospitalizations of patients over 65 are due to disorders of the colon which means that accurate analysis of history and clinical and instrumental investigation are mandatory. Our attention has been focused on x-ray examination using a double-contrast enema which, together with endoscopy, permits to diagnose colonic disorders with significant reliability. Our aim was to adapt the method to the special needs of the patient over 65 by employing the active substance trimebutine maleate (M.T.) as a "contact" pressure-lowering agent. Thirty-five subjects aged 65-75 with pathologies implying a risk for the use of parasympatholytic agents were examined. None of these patients showed side effects. It can therefore be said that the use of M.T. as a hypotonic agent in double-contrast enemas is an indisputable diagnostic aid.

[Opacity of the pterygo-palatine fossa]. / Le signe de l'opacité de la fosse ptérygo-palatine.

The pterygo-palatine fossa can be opacified because the invasion by pathologic tissue. This opacification, due to the loss of normal fatty content, has been found in 19 patients on 40 subjects affected by different maxillofacial pathology. The opacification of the pterygo-palatine fossa is a non specific sign and is generally associated with signs of bony involvement. This sign appears particularly usefull when the bony involvement is very slight and of in certain evaluation.

[Tomodensitometric evaluation of parosteal sarcoma. Concerning a case]. / Evaluation tomodensitométrique du sarcome parostal. Au sujet d'un cas.

The authors report a case of metaphyso-diaphyseal parosteal sarcoma of the thigh-bone. They analyse the CT signs and describe the possibilities of this method to acquire others tumour's signs, and to program a relatively conservative surgical act.

CT evaluation of a tympanic-jugular chemodectoma: a case report.

The authors describe a case of a chemodectoma involving the tympanic-jugular region, studied by means of Computed Tomography. They underline the utility of this method in spatial evaluation of such tumors.

[Metastases of the sub-arachnoidal space from medulloblastoma. Computed tomography study]. / Métastases dans l'espace sous-arachnoïdien dues à un médulloblastome. Etude tomodensitométrique.

A detailed analysis of C.T. finding with infiltration of the diffuse sub-arachnoidal space by medulloblastoma in a infant is reported. The C.T. sign who's same a cisternography with hydrosoluble contrast was in this case more helpful in obtaining the specific diagnosis.
